Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a support metal fitting used in a corner of concrete formwork such as construction, civil engineering, foundation work, highway and bridge.

[0002]

[Prior art]

 Conventionally, in the case of formwork construction such as concrete, for the corners when assembling the formwork into an L shape, for example, hollow prismatic steel pipes with a vertical cross section of 60 mm x 60 mm square are used on the outside and inside of the formwork, respectively. The two steel pipes, commonly called horizontal steel pipes, are combined at right angles, and vertical steel pipes are erected vertically at the intersections. To describe this state in more detail in three-dimensional terms, the X-axis direction and the Y-axis direction are described. The crosswise corners of the horizontal steel pipes combined in two-dimensional directions are assembled with a step at the top and bottom, and the corners are assembled inside or outside the assembled crossing pipes in the vertical direction. A vertical steel pipe is erected in the Z-axis direction, tied up with chains, numbered wires, etc., and if there is a fall, it is tightened with a turnbuckle, and the fall is reassembled before assembly.

[Problems to be solved by the device]

 In the conventional method of binding two horizontal steel pipes at a right angle, it is a laborious task that requires very skill to securely bind the intersection of the horizontal steel pipes in the X-axis and Y-axis directions at a right angle. If it is bad, the tip side is installed so as to be tilted, so the tip side becomes extremely narrow, and in addition, if the vertical steel pipe is bound in the Z-axis direction perpendicular to the intersection, these are further integrated. As a result, it is difficult to tie it up accurately in the three-dimensional directions of the X-axis, Y-axis, and Z-axis, and it is necessary to use a separator or turnbuckle more than necessary because it may fall over as a whole. In addition to this, in addition, there are many cases where straightening work is usually done from three sides or straightening work is performed to strike the pile to correct the inclination, and these troublesome works significantly reduce the work efficiency, and it takes time and effort even when dismantling. After work These work in order to again require a great deal of time and effort has been a major disincentive to prevent the reduction of the construction cost.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to integrally assemble them in the three-dimensional directions of the X axis, the Y axis, and the Z axis. The squareness of the three-dimensional direction of the intersection of the corners of the formwork can be guaranteed without fail, and the assembly and disassembly can be done with a simple one-touch operation, which significantly improves work efficiency and reduces construction costs. It is intended to provide a corner support metal fitting for formwork construction, which makes a great contribution.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the corner support metal fittings for formwork in the present invention are provided with a vertical steel pipe-attached column at a substantially central position in the longitudinal direction of the vertical steel pipe-attached column formed by a cross-sectional L-shaped steel column. A horizontal steel pipe backing plate in the X-axis direction, in which widthwise directions are made orthogonal to each other, and plate-shaped inner surfaces are fixed so as to form a T shape in a direction parallel to each outer surface, A horizontal steel pipe support top plate in the Y-axis direction is provided, and a horizontal steel pipe support top plate in the X-axis direction is provided on the outer surface of one end of the vertical steel pipe-attached column in parallel with the horizontal steel pipe support plate in the X-axis direction. The horizontal steel pipe support plate in the X-axis direction and the outer surface are fixed by forming a U-shape, and are attached to the outer surface of the other end of the vertical steel pipe-attached column in parallel with the horizontal steel pipe support top plate in the Y-axis direction. The X-axis is fixed by fixing the horizontal steel pipe backing plate in the axial direction by forming a U-shape between the horizontal steel pipe supporting top plate in the Y-axis direction and the outer surface. The wedge insertion hole bored in a substantially straight line orthogonal to the direction and the Y-axis direction each lateral steel tube supporting the top plate of the lateral steel pipe receiving plate is made of a wedge which is inserted into the wedge insertion holes.

【work】

 When the horizontal steel pipes K are respectively inserted into the U-shaped horizontal pipe fitting portions formed by the horizontal steel pipe support top plate in the X-axis and Y-axis directions, the horizontal steel pipe receiving plate, and the vertical steel pipe attachment columns, the horizontal steel pipes are heavy. When the wedges are inserted into the wedge insertion holes and contact one side of the horizontal steel pipe, the horizontal steel pipe is pressed against the vertical steel pipe impregnated column side by the pressing force due to the slope of the wedge. If a vertical steel pipe is inserted and inserted in the attachment column, the horizontal steel pipe that intersects at a right angle with a step due to the pressing force of the wedge and the vertical steel pipe T that intersects in the vertical direction are strongly and integrally fixed. It is possible to support the inside and outside of the corners of the L-shaped mold. (See Figure 3)
