Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a temporary support column used in formwork support and the like.

[0002]

[Prior art]

 In concrete construction of bridges and buildings, generally, formwork supports are used in which a large number of temporary columns are connected to each other by splicing materials and diagonal materials. There are various types of temporary stanchions. For formwork supports that support large loads, stanchions formed by bundling multiple pipe materials and struts made of thick square pipe are used. As the temporary support columns, generally, several types of support columns having different lengths are prepared, and by appropriately connecting them in the height direction, a support column having a predetermined height is configured.

[0003]

[Problems to be solved by the device]

 By the way, the load applied to the formwork support is not always applied in the vertical direction, and the load in the oblique direction and the horizontal direction also acts. In particular, the construction of arch concrete, etc. exerts a large horizontal force, and it becomes even stronger during an earthquake or strong wind. Therefore, in the formwork support work, it is necessary to firmly connect the temporary columns to each other.

Conventionally, the temporary columns are connected to each other by attaching a connecting member such as a clamp to the temporary columns and fixing a joint material or a diagonal member to the temporary columns. In addition to being insufficient, the load is concentrated on a specific part of the temporary support column, which may reduce the yield strength of the temporary support column. As a result, a large number of temporary support columns were used for the formwork support, and the problem was that the proportion of temporary construction costs in construction increased.

The present invention has been made in order to solve the problems of the above-mentioned conventional temporary support pillars, and enables the vertical connection of the temporary support pillars to be performed firmly, and the joint material and diagonal member between the standing temporary support pillars. The purpose of the present invention is to provide a temporary strut that can be firmly joined without being reduced in the yield strength of the temporary strut.

[0006]

[Means for Solving the Problems]

 The structure of the present invention for achieving the above object will be described with reference to the drawings corresponding to the embodiments. In the present invention, a plurality of arranged pipe members 1 and 1 are provided at both ends of the pipe members 1, and bolt holes for coupling are connected. A column member A formed by connecting end plates 2 and 2 provided with 4, 4 and connecting adjacent pipe members 1 and 1 with joint plates 3 and 3, and the end plate 2 described above. The coupling plates 7 and 7 are coupled to each other via the tubular body 6, and a plurality of joint plates 8 having mounting holes 10 are coupled to the tubular body 6 and the coupling plates 7 and 7 on the outside of the tubular body 6. End plates 2 and 2 of the support members 1 and 1 are joined to the connecting plates 7 and 7 of the connecting bracket B, respectively, and separated from each other by bolts and nuts 10 and 10. It is characterized by being freely combined.

【Example】

 A configuration of the present invention for achieving the above object will be described with reference to the drawings corresponding to the embodiments. The present invention provides a plurality of support members A, A and a connecting member for connecting the support members to each other. It consists of metal fittings B.

In the column member A, four pipe members 1 and 1 are arranged in an enclosing shape with a space therebetween, and both ends thereof are fixed to the four sides of the end plates 2 and 2 by welding or the like. At the same time, the pipe materials 1 and 1 are connected to each other by a plurality of splice plates 3 and 3 having a width in the length direction of the pipe material 4 at intervals in the length direction of the pipe material 4. Further, at least four corners of the end plate 2 are provided with bolt holes 4 and 4 through which connecting bolts and the like are inserted, and at the center of the end plate 2, a screw rod of a jack is provided as necessary. There is a hole 5 for inserting the like. The shape of the end plate 2 is not limited to the quadrangle as shown in the drawing, but may be a circle, a polygon, or the like.

The connecting fitting B has concentric connecting plates 7, 7 of substantially the same shape as the end plate 2 at both ends of a short cylindrical body 6 whose plane shape is smaller than that of the end plate 2. And a plurality of joint plates 8 having the same width as the height of the cylinder 6 are welded to the outside of the cylinder 6 so as to extend to the outside of the joint plate 7. Has been projected by. The connecting plates 7 and 7 are provided with bolt holes 9 and 9 corresponding to the bolt holes 4 and 4 of the end plate 2, and the joint plates 8 and 8 are connected to other temporary columns or the like. A mounting hole 10 for connecting a connecting member (not shown) necessary for this purpose is provided.

The temporary strut of the present invention is formed by connecting the strut members A and A described above in the lengthwise direction through a coupling fitting B. That is, the end plates 2 and 2 of the column members A and A to be joined to the joining plates 7 and 7 of the connecting fitting B are joined to each other, and the bolts and nuts are utilized by using the bolt holes 4 and 9. Tighten and join 11 and 11. The present invention is not limited to the combination of the two pillar members A as in the above-described embodiment, but a required number of pillar members A may be formed in the same manner as above depending on the required length of the temporary pillar. It can be connected via a connecting fitting B. In practice, it is advisable to prepare several kinds of strut members A having different lengths, and to use them by combining them at the height required on site. Then, after using it as a temporary support, if you remove the connection with bolts and nuts 11, 11 as needed, it will be convenient for transportation and storage, and will also be used for the support member A and the connecting bracket B respectively. Appropriate diversion can be achieved.

[0011]

[Effect of device]

 As described above, since the temporary support column of the present invention separably connects a plurality of support column members through the connecting metal fittings, if a plurality of support column members having different lengths are prepared, the combination of them is possible. Thus, a temporary support column having a required length can be easily formed, the utilization of each member is high, and the cost of the temporary support material can be reduced.

In addition, the strut member joins a plurality of pipe members with the end plate and the joint plate, and the connecting fitting has the short tubular body, the joining plate, and the joint plate integrally joined. In addition, the strength and rigidity are great, and since the strut members and the connecting fittings are joined by the face-to-face contact between the end plates and the joint plates and bolting, a solid temporary strut can be formed as a whole. Further, since the temporary columns are connected to each other or to other structures or the like by the joint plate portion of the connecting metal fitting, the structure of the support work by the temporary columns can be strengthened.
