Description

[Detailed explanation of the idea] In the construction of concrete buildings, when constructing ceilings or floors above floors, the temporary floor boards on which concrete is poured are lined up with panels, etc. This is done with construction beams via joists or daihiki.

This was done using supports to support construction beams, but supporting construction beams directly with supports requires a large number of supports and requires less space under the construction beams. The construction work was often inconvenient.

Therefore, when constructing the upper floors and beams of a concrete building at the same time, we fix construction beam brackets to the top of the temporary side frames that surround the beams, and use these brackets to It is possible to support both ends of the beam, but supporting the temporary floorboards, joists, construction beams, concrete, etc. that make up the upper floor only with the upper part of the temporary side frame is not recommended. The strength must be extremely high, and if a simple temporary side frame such as a conventional temporary side frame made of plywood was used, the temporary side frame itself could be destroyed.

In view of the above, the present invention is designed to support construction beams in the temporary side frame even when the strength of the temporary side frame is not very high.The following is an example of the present invention explained with reference to the drawings. , engages with the upper part of the temporary side frame 15 for guarding the beam part of a concrete building, or works in conjunction with the coupling part 2 and wedge 3 that is fixed to the upper part of the temporary side frame 15 by nailing etc. A male threaded member 5 is fixed under the beam support main part 1 having a receiving part 4 that supports the beam 22 so that its central axis direction is vertical, and a female threaded member 6 is screwed into the male threaded member 5. A pipe-shaped support rod 7, which is rotatably attached to the top of the pipe, is provided with a plurality of horizontal pin insertion parts 8 with gaps above and below, and is used as a temporary bottom plate 16 or a temporary base plate for constructing a beam part of a concrete building. For concrete construction, a support part 10 for a penetrating pin is provided on a receiver 9 that is fixed to the vicinity of the temporary bottom plate 16, such as a large drawer 17 that supports the bottom plate 16, and a stopper 18 that is integrated with the temporary bottom plate 16. The present invention is implemented by constructing a beam receiving device.

In the figure, 11 is a mounting piece for the receiver 9, 12 is a nail insertion hole for fixing the receiver 9 to the temporary bottom plate 16, the main drawer 17, the crosspiece 18, etc., and 13 is the support rod 7 and the female screw member 6. 14 is an annular groove into which the set screw provided on the female threaded member 6 is fitted; 19 is an end interposed between the temporary bottom plate 16 and the main drawer 17; Thick wood, 20 is support, 21
is a crosspiece fixed to the upper end of the temporary side frame 15 for reinforcing the temporary side frame 15. In the device of the present invention, the above-mentioned crosspiece 21 is horizontally suspended over the upper end of the temporary side frame 15, and the beam support main part 1 When the connecting portion 2 of the temporary side frame 15 is hung across a structural part such as plywood forming the temporary side frame 15 and the above-mentioned crosspiece 21, the gap between the beam receiver main portion 1 and the plywood of the temporary side frame 15 is suspended. Beam receiver main part 1
It is possible to support the construction beam 22 without deforming it.

23 is a temporary floor board supported by construction beams, and 24 is concrete that has been poured.

In addition, when implementing the present invention, if the position of the mounting piece 11 of the receiver 9 is provided to protrude laterally from the insertion part of the support rod 7, the mounting piece 11 can be attached to the temporary side frame 15, for example, as shown in the first figure. It can be installed as close as possible to the temporary side frame 15, and can also be fixed to the opening stopper 18 of the temporary side frame 15. In this case, a thick piece is placed in the middle of the temporary side frame 15 for reinforcement. Even if it is installed, it will not hinder the construction work, and the intermediate thick material can also be held with a support rod.

The present invention is as described above, and the main beam support part 1 is supported at the upper end of the temporary side frame 15, and also supported in the vicinity of the temporary bottom plate 16 for constructing the beam part of a concrete building. There is no need to increase the strength of the frame 15, and construction work can be carried out using the temporary side frame 15 made of ordinary plywood as it is.

In addition, in the device of the present invention, since a plurality of pin insertion holes 8 are provided in the support rod 7, it is easy to greatly change the distance between the lower receiver 9 and the beam receiver main part 1. It is easy to finely adjust the distance between the receiver 9 and the beam receiver main part 1 between the member 5 and the female screw member 6, and the receiver 9 as a whole can be easily adjusted.
The distance between the main beam receiving part 1 and the main beam receiving part 1 can be set extremely quickly and accurately to the required value.

Furthermore, since the device of the present invention can be used repeatedly, it is useful for reducing construction costs by using it for a long period of time.
