[Industrial applications]

 The present invention relates to a method of supporting a form such as a beam or a slab during concrete pouring or curing and a support used for the method.

[0002]

[Prior art]

 When building beams and slabs by concrete pouring during construction work, etc., a formwork for concrete pouring must be formed in advance. Previously, the method of assembling the formwork directly to the site where concrete was poured was used, but in recent years the formwork has been preassembled at another place or in the field, and it is labor-saving to set it with a wrecker. The chemical method is adopted. The molds are set by holding the molds in place and passing the thick corners under the molds, and supporting the thick corners with supports.

The above-mentioned support is generally called a pipe support, and as shown in FIG. 3, an upper column pipe b having a flat thick end plate a on one end of the pipe and a flat base on one end of the pipe. It is composed of a lower column tube d provided with a plate c. Insert the pipe end of the upper pillar pipe b into the pipe end of the lower pillar pipe d, and adjust the height of the support while adjusting the insertion amount appropriately, The upper pillar pipe b and the lower pillar pipe d are connected in between so that the thick corner A can be supported from below. Conventionally, when supporting the thick corner A by the upper column tube b of this support, the support plate a is fixed to the lower surface of the sharp corner with nails e so that the support position of the support does not deviate from the thick corner A. I needed to.

[Problems to be solved by the device]

 However, when using a conventional support, it is necessary to nail the backing plate to the bottom surface of the thick corner so that the displacement of the supporting position does not occur as described above, and therefore it is necessary to purposely provide a scaffolding. It was Even when there was no scaffolding, stepladders were often used. Therefore, it is necessary to perform nailing work on a scaffold at a high place or on an unstable stepladder.Furthermore, depending on the place, the worker may bend down in a cramped place, which may improve work efficiency and safety. It was by no means a favorable working environment. In addition, when building a scaffold, it is necessary to carry in and assemble the materials for the scaffold, dismantle the scaffold after the work is completed, and carry out the materials, which requires a lot of work and promotes labor saving on site work. It was one of the problems.

[0005] Therefore, an object of the present invention is to provide a support for supporting an edge corner and an attached fixture that do not require nailing work at a high place using a scaffold or the like.

[0006]

[Means for Solving the Problems]

 In order to achieve the above purpose, a support plate with a thick corner is installed at the mouth edge of one end of the pipe to support the thick corner supporting the beam or slab formwork during concrete pouring or curing. It consists of an upper pillar pipe and a lower pillar pipe with a base plate at one end of the pipe. A support bracket that is detachably attached to a support that is used by interposing the upper column pipe and the lower column pipe between them, and a connecting member that can be detachably attached to the receiving plate of the thick edge, A thick corner support is provided.

Further, the connecting member is an inserting member capable of being removably inserted into the pipe opening portion of the receiving plate of the upper pillar pipe, and the edge thick corner support portion is provided at the upper end of the inserting member, and the edge thick corner is also provided. A plate material having a protrusion capable of penetrating into the surface was used. In addition, the connecting member is an insert member that can be detachably inserted into the pipe opening of the receiving plate of the upper pillar pipe, and the plate member having a nail hole on the surface with the thick corner support portion provided at the upper end of the insert member. It was

[Action]

 Since the support receiving object of the present invention is composed of a connecting member that can be attached to and detached from the receiving plate of the upper pillar pipe of the support, and the thick corner support portion provided on it, only the support receiving object is separated from the support, It can be preliminarily erected at the support support position of the thick corner. Therefore, when the form is set, it is possible to support the thick edge corners only by attaching the support receiving plate to the support receiving member connecting member which is previously provided at the thick edge corners.

Particularly, in the case where the projection is provided on the surface of the edge corner supporting portion and the projection can be inserted into the edge corner to be fixed, the projection is inserted into the edge corner in advance in the ground assembly stage. Since it can be kept in place, it is possible to omit the penetrating work of strongly pressing the entire support toward the thick corner when supporting the support. In addition, since the connecting member is an insertion member that can be removably inserted into the tube opening on the receiving plate surface, it has basically been used in general since the type having the tube opening on the receiving plate surface. The support can be used as it is, and the usability of the support receipt can be secured. Further, by providing a nail hole other than the projection in the thick corner support portion of the support receiving object, the support receiving object can be nailed in advance to the thick edge corner.
