Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an improvement in a method for attaching a floor plate for concrete pouring of a building standpipe unit.

[Prior art] An example of a standpipe unit for construction is explained below. As shown in Figure J3, a unit frame 3 is formed by incorporating horizontal frames 2 at fixed height intervals into vertical frames 1 at the four corners, and the concrete floor of each floor is placed at a fixed height position of this unit frame 3. A floor plate 4 for concrete pouring is attached to the upper, middle, and lower three levels for three floors, and a plurality of standpipes 5, for example, three standpipes 5 are inserted through the floor plate 4 for concrete pouring. , the lower part of each standpipe 5 is fixed to two support bars 7 provided at the lower part of the unit frame 3 with a fixing hardware 6, and the middle and upper part of each standpipe 5 are fixed to the middle and upper part of the unit frame 3. Nuts are tightened to both ends of the U-shaped metal fittings 8, which are held by the U-shaped metal fittings 8 that are penetrated by the support beams of each tree provided in the support beams 7. A pipe sleeve 9 is provided in the two halves of the standpipe 5 that pass through the floor plate 4 for concrete placement, and is filled with a heat insulating material and a non-combustible fireproof material.

[Problems to be Solved by the Invention] By the way, in the construction standpipe unit 10 having the above configuration, in order to attach the floor plate 4 for concrete pouring, it has conventionally been necessary to use a After the through holes 11 were drilled in the floor plate 4 for concrete pouring, the assembly was fixed at a predetermined position on the unit frame 3. Therefore, after that, the long standpipe 5 must be inserted from the end of the unit frame 3 into the pipe sleeve 9 or the through hole 11 to be assembled, which results in poor workability and reduces labor in manufacturing the construction standpipe unit 10.
It was not possible to transform the grass into ridges.

In addition, if a branch pipe is attached to the standpipe 5, it is impossible to insert it into the pipe sleeve 9, so the pipe sleeve 9 is fitted to the straight standpipe 5, and the floor plate for concrete pouring is
After fitting the pipe sleeve 9 to the concrete pouring floor plate 4, attaching the branch pipe to the standpipe 5, and then assembling the stand pipe 5 together with the concrete pouring floor plate 4 into the unit frame 3. It takes a lot of man-hours because it has to be done.
The construction standpipe unit 10 could not be manufactured efficiently, and the workability was extremely poor. Moreover, sometimes I forgot to fit the pipe sleeve 9 into the standpipe 5.

Therefore, the present invention has been devised so that the standpipe does not need to be inserted into a pipe sleeve or a through hole in a concrete floor plate, and even if the standpipe has a branch pipe, it can be easily assembled into the unit frame. The present invention attempts to provide a method for attaching a floor plate for concrete pouring to a frame.

[Means for Solving the Problems] In order to solve the above-mentioned IUA, the method for attaching a floor plate for concrete pouring of a standpipe unit for construction of the present invention involves fixing a plurality of standpipes to a support crosspiece provided on a unit frame. After that, a plurality of concrete pouring floor plates having a through hole passing through the standpipe and divided so as to bisect the through hole are attached to the horizontal frame of the unit frame so as to sandwich the standpipe. It is something.

[Function] As described above, the method for attaching the floor plate for concrete pouring of the architectural standpipe unit of the present invention involves incorporating and fixing a plurality of standpipes into the unit frame, and then dividing the standpipe into a plurality of parts so as to sandwich the standpipe. Since the concrete pouring floor plate is attached to the horizontal frame of the unit frame, there is no need to insert a long standpipe from the end of the unit frame into the pipe sleeve or the through hole of the concrete pouring floor plate as in the conventional case. Even if the pipe has a branch pipe, it can be easily incorporated into the unit frame without any problem.

[Example] An example of the method of attaching a floor plate for concrete pouring of a standpipe unit for construction according to the present invention will be described with reference to the drawings.As shown in FIG. Assembling, the lower part of each standpipe 5 is fixed to two support bars 7 provided at the lower part of the unit frame with fixing hardware 6, and the middle and upper part of each standpipe 5 are fixed to the middle and upper part of the unit frame, respectively. A U-shaped metal fitting 8 that can be penetrated through one support bar 7 provided in the
Hold it in place, and tighten nuts on both ends of the U-shaped metal fitting 8 to fix it. Thereafter, as shown in Fig. 1C, two concrete casting floor plates 4' having three through holes 11 passing through the vertical pipe 5 and divided so as to bisect the through holes 11 were prepared. , standpipe 5
Welded to the lower surface of the horizontal frame 2 of the unit frame 3 so as to sandwich it. Thereafter, a pipe sleeve 9 for filling with a heat insulating material and a non-combustible refractory material is installed in the two halves of the standpipe 5 which need to be insulated, passing through the concrete casting floor plate 4°, as shown by the chain line in FIG.

Another embodiment will be described with reference to the figure 'H2. After incorporating six rows of standpipes 5 into the unit frame 3 and fixing them by the same means as described above, the through holes 11 passing through the standpipes 5 are inserted into the rows. Three floor plates 4'' for concrete pouring, which have six pieces and are divided so as to bisect the through hole 11, are welded to the lower surface of the horizontal frame 2 of the unit frame 3 so as to sandwich the standpipe 5 therebetween.

In this way, the method for attaching the floor plate for concrete pouring of the architectural standpipe unit of each embodiment is to install and fix a plurality of standpipes 5 to the unit frame 3, and then divide the standpipe 5 into a plurality of sections so as to sandwich the standpipe 5 therebetween. Since the floor plate 4 for concrete pouring is welded to the lower surface of the horizontal frame 2 of the unit frame 3, the long standpipe 5 is connected from the end of the unit frame 3 to the pipe sleeve 9 and the floor plate 4 for concrete pouring. Through hole 1
1, and even if the standpipe 5 has a branch pipe 12, the standpipe 5 can be easily assembled into the unit frame 3 without any problem.

In addition, each of the above-mentioned examples is a floor plate 4 for concrete pouring.
°, 4'' is welded to the lower surface of the horizontal frame 2 of the unit frame 3, but it may also be welded to the upper surface.Also, it is not limited to welding, and may be attached to the horizontal frame 2 with screws. It is.

[Effects of the Invention] As explained above, according to the method for attaching the floor plate for concrete pouring of the standpipe unit for construction of the present invention, the standpipe can be easily installed without inserting the standpipe into the through hole of the pipe sleeve or the floor plate for concrete pouring. It can be assembled into the unit frame, and even if the standpipe has a branch pipe, the standpipe can be easily assembled into the unit frame. Therefore, the workability of assembling the standpipe into the unit frame is improved, and it is possible to save labor and improve efficiency in manufacturing the standpipe unit for construction.

Furthermore, after the standpipe is assembled into the unit frame, the divided floor plates for concrete pouring are attached to the horizontal frames of the unit frame so as to sandwich the stand pipe, so that the work of attaching the floor plates for concrete pouring is easy.
