Hello, everyone! This is Kikuchi Souken Company Limited website.

Our company office is based at Ikebukuro, Toshima ward, Tokyo, and in all over Kanto district, we are taking charge of《Interior decorative construction work》generally and《Recovery and restoration construction work》for you.

 

This time, we are roughly explaining hat joint construction work.

 

It is the latest version article which we also introduced before.

 

Hat joint construction work

https://kikusou-gr.com/wp/%e3%83%8f%e3%83%83%e3%83%88%e7%9b%ae%e5%9c%b0%e6%96%bd%e5%b7%a5/

 

As many of you probably wonder what on earth is hat joint?
So, we are briefly explaining it in this article at first.

 

If you do not need to read that explanation, and would like to see our construction work situation, then please directly visit and see the subtitle of「Hat joint construction work situation」below.

 

 

In the first place, What is joint?

 

Firstly, besides gypsum board which we are explaining this time, joint is pointed to be a gap arising between construction materials such as tile, stone materials and so on.

 

You may possibly have seen「 cauking 」was done between bricks at that mesh patterned joint between bricks and in the toilet or wet area.

 

 

As we above-mentioned, depending on materials, joint is cauked, is thrusted and filled with putty and so on, or joint materials such as joiner is embedded.

 

The work, Joiner seems to have the nuance of「 tying thing」.

 

 

The reason why we treat joint.

 

The reason why we treat joint varies a lot depending on the places and part materials. The biggest and main reason and role can be probably said「 Cutting the edge, and preventing each material from interfering and wearing. 」

 

 

Depending on the temperature and humidity, there is a possibility of materials occurring shrinking, crooking and so on.

 

Furthermore, because of external factors such as earthquake and so on, materials may also occur to be pushed out or pulled in toward all the direction.

 

Therefore, by taking joint a little widely or so, chances are that it is often executed constructing work to be able to buffered。

As for other purpose, there is an addition of decorativeness.

 

The joiner which we are introducing this time is a kind of joint material(changeoff material) 「which can make joint to finish with a certain interval」.

By inserting and sticking joint, there is a merit of preventing it from interfering materials each other, while making materials appear neatly.

 

There are various kinds of joiners. Comparing with the case of simply embedding calking, it can make a good joint in appearance.

 

Component materials used at different finishing places each other such as joiners, or component materials to be used at constructing different direction parts crossed such as ceiling and wall part are called 「changeoff material」.

 

We may be also going to introduce other changeoff materials later.

 

 

Hat joint construction work situation

 

Our introductory remark may have been long so far, however, we are explaining the situations of hat joint construction work site at a certain office warehouse from here.

 

 

ハットジョイナー施工中の様子

Actually just under executing joiner situation.
In order to execute joiner, the joint is taken out rather largely than vertical direction boards’ joint each other.

 

 

 

Because the picture is taken as slightly going down, it may not be very clear, please pay close attention to the worker’s hand.

 

Rather larger joint than usually was being made in the horizontal direction. We are going to insert 「hat joiner 」in this gap.

 

As the joint cross section looks like silk hat, it is called hat joiner.

 

The purpose of inserting joiner this time is「Upper part by painting, and lower part by so- called decorative cross finishing, cutting the edge is recommended.」.

 

As above-mentioned, in the case of mutual materials, especially in the case that the material and the finishing or so are different, we can say that「cutting the edge」construction work is indispensable.

 

By cutting the edge, we can reduce what to affect painting or sticking so-called decorative cloth for external factors such as humidity, earthquake and so on.

 

In this connection, hat joiner is also used for outside wall part joint, besides interior decoration.

(The joiner for outside wall use is different from that of interior decorative use on size and material very much. )

When embedding joiner, we go on sticking at the back side of joiner with glue.

 

At this time, in order not to leave too much glue, and in order to be able to stick firmly, we carefully go on executing construction work.

 

If leaving too much thickness, when finishing putty treatment, it is getting hard to flatten it, and it will take time for adjusting it.

 

Because it is going to be hard to adjust it by work operation as time goes on, the first step is crucial.

Finish gluing hat joiner situation.
After this, we do patty treatment again. We go on adjusting the bedding to flatten gypsum board surface.

 

 

 

The direct above picture is the situation of already finish gluing hat joiner generally.

 

After this, same as the mutual gypsum boards joint and the screw fixing place, we do putty treatment. After that, when sticking so-called decorative cloth and painting, we adjust not to arise floating or 凹, and we actually transfer the work site to the following painting・sticking so-called decorative cloth construction work process, then our work is finished.

 

 

 

 

Summary

 

We so far roughly explained hat joint construction work about the joint construction work itself, and the actual construction work situation as above.

 

As this time, in the case of different finishing at the upper part and lower part or so, 「cutting the edge 」of joiner and executing construction work of changeoff material happen to be often.

 

Upon your request, it is certainly possible for us to execute the relative construction work.

 

Besides, if you happen to have questions・counselling and so on such as「At the place like this, how should I request construction work?」, please be sure to talk with us light heartedly.

 

It is possible for us to answer for the . whole process, and part of the process construction work too. So, we are waiting for your relative inquiry.

From price quotation up to construction work completion, our company is directly managing and doing construction work by ourselves. Our aim is supplying 「reasonable construction work as much as possible, and high quality, better work service」to our customers.

Hello, everyone! This is Kikuchi Souken Company Limited website.

Our company office is based at Ikebukuro, Toshima ward, Tokyo, and in all over Kanto district, we are taking charge of executing construction work of《Interior decorative construction work》generally《Recovery and restoration construction work》for you.

 

This time, we are thinking of roughly explaining,

 

Inspection hole, and its installation construction work, which comes to be related to interior decorative construction work, and its facility work.

 

What is inspection hole? And on its role.

 

Inspection hole is, by executing construction・installing at the ceiling, wall, floor and so on, you will be able to check and diagnose・examine inside situations.

 

As we will below-mention it, however, according to what to be「watched・checked」inside, it is executed construction・installation at various places.

 

Places where inspection hole is installed.

 

Ceiling

天井点検口参考画像

Situation of general ceiling inspection hole.

 

 

Inspection hole installed at the ceiling, is called「ceiling inspection hole」just as it is.

According to various checking items, there are a lot of plural places existing on the same floor too.

 

According to manufacturers, there are such products named as「ceiling hatch」「high hatch」and so on. Hatch=moving up and down way, entrance hole with lid.

 

Main inspection items are:

 

  • ●Electricity, internet wiring.
  • ●Ventilating fan duct.
  • ●Housing diagnosis.

and so on.

 

However, as for interior decorative construction work, if stain of water leakage at the ceiling due to rain leakage should be found, situations are checked from inspection hole too. Or, inspection hole may be tentatively newly installed, and may be checked inside.

 

As for residence which has attic storage, there is such kind of ladder for moving up and down at attic, a ladder when it opens, it will come to be pushed out as open hole part too.

 

Above these can be also said a kind of inspection hole, as the meaning of attic inspection.

 

In old Japanese style residence, chances are that there is not inspection hole often.  Such residence at upper part of closet storage or a sheet of board at storage space above closet can be pushed and removed. From there, inspection and diagnosis can be carried out.

 

Wall

 

There are not many places which is attached to wall inspection hole.

In many cases, it is installed inside housing apartment, unit bath, or washroom.

 

Its main inspection item is,

 

Piping arrangement (water supply and drainage equipment)

 

Underfloor inspection hole

床下点検口、並びに床下収納の参考画像

An example of underfloor inspection hole, and underfloor storage.

 

 

Underfloor inspection hole can be often noticed at the kitchen, and it is often combined with underfloor storage too.

 

Its main inspection items are,

 

  • ●Underfloor piping arrangement(water supply and drainage)
  • ●Residence diagnosis(Basic situation, grasping termite and ant damage situation, humidity and so on)

 

As this, inspection hole inside is usually not noticed very much.

Naturally, by checking inside, various situations in the building can be grasped.

So, in building maintenance work operation, it is an indispensable equipment.

 

As we explained above, it is equipped in various places, so all of them are necessary open holes.

 

Regarding temporary installed inspection hole, its procedures.

 

As we explained ceiling inspection hole above, if rain leakage should occur at the ceiling, or if electric wiring should be newly done in the existing building or so, there is an occasion of executing construction work and installing temporary installation of inspection hole.

 

We are roughly explaining its procedures.

 

This time, we are explain by taking up an example of「inspection hole installation for water leakage」.

 

① Selecting open hole place, and width.

 

Checking rain leakage at the ceiling with eyes. In the first place, checking if the location of water supply and drainage pipe can be noticed from existing inspection hole.

 

If the situation can be grasped from already installed inspection hole, it is not necessary to newly install inspection hole.

 

Check the situation of water supply and drainage pipe from already installed inspection hole first. If it is judged that its cause or problematic place cannot be confirmed or cannot be confirmed from that location, then, we will prepare to install temporary installation of inspection hole at a suitable place.

 

② Studying temporary installation of inspection hole place(testing, marking)

 

If identification of the cause or grasping the situation could not be done by above ①, then, we go on selecting a place for temporary installation of inspection hole.

 

At closely connected structure building body part, if it should be opened, then, its strength may be going down. While, if the cause identification or grasping situation from opened place cannot be done, then, there is going to be meaningless of opening it.

Therefore, we shall study where to open hole carefully.

 

 

吊り天井、並びに軽鉄下地の様子

As a reference, we have prepared a situation picture inside the ceiling clearly as above. In this picture, as reinforcement of earthquake is done more, bedding material is dense.  By and large, LGS(=light gauge steel) bedding is mounted square-shaped as this. Wiring, piping, and duct are stretched around at the roof space.

 

 

 

As it is off the subject, however, in order to open inspection hole without hurting bedding material, we sometimes use board cutter too.

 

ボードカッターの参考画像(マキタ公式サイトより拝借)

Above is Makita Co. product board cutter reference picture. It can be eventually cut off by letting blade at picture upper part push against board material, slowly going on to move blade just as drawing a line, then cutting it off. Picture quoted from Makita Co. official web page.

It can be eventually cut off by letting blade at picture upper part push against board material, slowly going on to move blade just as drawing a line, then cutting it off.

Picture quoted from Makita Co. official web page.

 

By pushing blade against board material at upper part, slowly going on by moving it, then you will be able to cut it off just as saw.

 

It is possible to adjust blade length, and only cut off board material without hurting bedding material. Transparent area at the right part of the picture is dust box, so it can reduce powder dust.

 

As we may have averted from our explanation a little, when opening hole after all, in order not to hurt bedding material, by using needle for searching bedding or a tool called sensor, then  we cut off board material.

 

③ Cutting off board material, then opening hole. After that, depending on circumstances, strengthening opened inspection hole, and installing inspection hole frame, then it is finish of the installation.

 

Checking the size in advance, and do marking so as to fit the inspection hole, then going on opening hole.

 

As for hollowed out board material, if it does not have hurt, it can be used as the lid as it is. So, we shall store it where it is easy to be located, not to throw it away.

When opening hole, it will definitely come to require to cut off a piece of joist.

So, we shall do work operation of strengthening opened hole in order to recover strength at the cut off part.

 

After finish strengthening opened hole, finally, we attach outer frame to the opened hole place, and attach hollowed out board material to the inner frame. Then, we fix both with metal fitting. If we can confirm smooth opening and closing, the installation work is thus finished.

 

It seems that there may not be enough chance to look at it carefully, however, in our abovementioned explanation, as there is「standard type」, there are various materials・kinds of inspection hole too.

 

There is an inconspicuous type of it too. So, if you would like to install for regular checking, not for temporarily, we would like to suggest you to tell us of that effect.

 

We so far have explained inspection hole installation above with a little bit redundancy.

 

Explaining construction work example including inspection hole installation.

 

As we previously executed construction work of interior decorative bedding at a food court tenant of commercial facility, we are explaining that situation as below.

 

As it is a large scale renovation, we re-sticked each place of LGS (=light gauge steel) bedding and board material too.
