Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a temporary support mainly suitable for use in formwork support and the like.

(Conventional technology) Pipe supports with trestles and jacks are used for formwork shoring that supports slab formwork and beam formwork in buildings, etc., and pipe supports are used in buildings with low floor heights. Although it is often used, in cases where the floor height is high, a pipe support made of a round pipe with a jack built in is not strong enough, so recently temporary supports made of a strong square pipe with a jack built in are being used. It has become like that.

(Problem that the invention aims to solve) However, even with the above-mentioned temporary supports, they are connected to each other in the horizontal direction to form a shoring structure, but in order to do so, traditional pipe supports made of round pipes are used. Similar to shoring, connecting materials are used to connect the structures, and this generally involves fixing steel pipe clamps to the temporary supports via fittings, and then tightening the connecting materials to these clamps. There is. Therefore, when erecting temporary supports, it is necessary to tighten the connecting materials while keeping each temporary support vertical, which not only requires a lot of manpower and is troublesome, but also prevents the temporary support from being vertical. There were many construction and economical problems, such as the need for special equipment to measure the temperature.

The present invention was developed in order to eliminate these shortcomings in temporary supports.It fundamentally improves the structure of temporary supports, allows for easy and reliable connection of temporary supports, and improves support. This is an attempt to provide a basis for the efficient and economical implementation of the engineering hypothesis.

(Means for solving the problems) Regarding the configuration of the present invention, the first
To explain with reference to FIGS. 4 to 4, the present invention has four rods 2, 2 bound to the four corners of rectangular binding plates 3, 3 having wedge holes 5, 5 on all sides. The strut body 1 is formed by integrally binding and fixing to both ends thereof an end plate 7 which communicates with a through hole 8 in the center and is provided with a steady rest tube 9. , a jack 10 with an adjusting nut 13 screwed onto a screw rod 11, and a steady rest tube 9 with the screw rod 11
It is characterized by being inserted and installed in the.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

In Figures 1 to 4, 1 is the support main body, 4
Rods 2, 2 made of book tubes or the like are integrally bound by a plurality of binding plates 3, 3 arranged at intervals. The binding plate 3 is formed in a rectangular shape, and has fitting grooves 4, 4 at its four corners that engage with the rod 2, and wedge holes 5, 5 between each fitting groove 4, 4.
is provided, and a round hole 6 is provided in the center. Then, the four rods 2, 2 are connected to each binding plate 3,
3 are engaged with the fitting grooves 4, 4, and are connected to each other by welding or the like, and are integrally bound, and end plates 7, 7 are fixed to both ends of the bundled rods 2, 2. ing. The end plate 7 has a jack 1, which will be described later, in the center.
A through hole 8 is provided through which the threaded rod 11 of No. 0 is inserted, and communicates with this through hole 8 so that the screw rod 1
A steady rest tube 9 accommodating 1 is fixed, and the other end of the steady rest tube 9 is fitted into a round hole 6 of the binding plate 3 and fixed.

Reference numeral 10 denotes a jack, and an adjustment nut 13 having a handle 14 on a threaded rod 11 having a support plate 12 fixed to one end.
are screwed together. And this joke 10
Two steady rest pipes 9 and 9 are prepared for the above-mentioned support main body 1, respectively, and are provided at both ends thereof.
It is attached by inserting screw rods 11, 11 into 9.

Therefore, with one support plate 7 in contact with the floor and the support body 1 standing upright, by turning the adjustment nut 13 screwed onto the lower screw rod 11, this screw rod 1 can be adjusted.
The support main body 1 moves up and down with respect to the adjustment nut 13 screwed into the upper threaded rod 11.
By turning , the upper screw rod 11 moves up and down with respect to the support main body 1.

FIG. 5 to FIG. 8 show an embodiment in which a plurality of temporary supports of the present invention are connected.

Each upright temporary support is connected using a connecting material 15 as shown in FIG. Tie material 15
is formed by providing anchoring bodies 17 at both ends of a steel pipe 16, which can be freely engaged with and detached from the binding plate 3 of the support main body 1. The anchoring body 17 is formed into a tubular shape that fits around the steel pipe 16, and has grooves 18, 18 facing each other at the tip thereof into which the binding plate 3 can be inserted, and grooves 18 facing each other in the direction orthogonal thereto. Wedge holes 19, 19 are provided through which the wedge 20 is inserted. and,
As shown in FIGS. 5 to 7, the connecting material 15 is assembled by engaging the cutout grooves 18, 18 of the anchoring body 17 with the portion between the two rods 2, 2 of the binding plate 3. The wedges 20 are driven into the wedge holes 19, 19 of the attached body 17 and the wedge hole 5 of the binding plate 3 to bind them together. Further, disassembly can be easily performed by removing the wedge 20.

This connecting material 15 can be attached in an appropriate number of locations at appropriate locations by using any of the binding plates 3 provided on the support main body 11. For example, as shown in FIG.
A temporary structure can be formed by connecting the tie material 15 between the three, resulting in a shoring structure with great strength and rigidity. The height can be adjusted by appropriately rotating the lower or upper adjustment nut 13 depending on the construction situation. The support plate 12 at the upper end normally supports a beam material that supports the slab formwork, a girder material that supports the beam formwork, and the like. When removing the formwork after pouring concrete, it is sufficient to rotate the adjusting nut 13 to lower the height of the temporary support and then remove it.

(Effects of the invention) As explained above, the temporary support of the present invention integrally binds four rods by binding them to the four corners of a rectangular binding plate with wedge holes on all sides. An end plate with a steady rest pipe connected to the through hole in the center is fixed to both ends to form a support body, and a jack with an adjustment nut screwed to a threaded rod is attached to both ends of the support body. Since the screw rod is inserted into the steady rest pipe and installed, the main body of the column has a large section modulus due to the binding of the four rods with the binding plate, and is not only strong against compressive force, but also resistant to bending and bending. It is resistant to buckling, so it is possible to form long objects that are both lightweight and strong.Since the jacks are inserted into the column body for installation, the column body and the jacks can be freely connected and separated. This allows for easy transportation and temporary construction work. In addition, the binding plate of the main post body has wedge holes between each rod, so you can easily connect the tie materials using wedges, and connect the temporary supports together. It has many advantages, such as being able to form a shoring structure with great strength.
