Abstract

The present invention is a formwork fixture for earth wall to form a formwork and to fix the formwork to form a concrete wall inside the earth wall generated by the excavation work for civil engineering or building construction, and basement concrete such as apartment, officetel, commercial building, etc. If the structure is plywood, instead of the existing method of fixing and supporting the form tie and tiba in the plywood formwork, the upper and lower parts of the H beam are fixed by fixing the upper and lower parts of the H-beam in order to solve the waterproof problem and shorten the plywood construction period. It is effective in securing working spaces such as reducing material and labor costs and reducing construction risk.

Description

Fixing apparatus of cast using a dirt wall}

The present invention relates to a formwork for earth wall formwork to form the formwork to form a concrete wall in the earth wall inside the earthwork generated by the excavation work for civil engineering or buildings to fix the formwork.

Conventional fixture is fixed by inserting a fastener formed integrally with a fastening ring formed at the end between the laminated horizontal beam and the beam fixed to the end fixed to the formwork to form the thickness of the concrete wall with a wire or elongated bar Will be done. This work has the disadvantage that the work is difficult when fastening the spacing of the formwork and the supporting wire to the hook of the fixture.

As is well known, an earth wall is formed by digging ground when performing civil works (earth wall formed by digging, including construction work). A safety wall has been constructed by constructing a concrete wall to prevent the soil from flowing out of the earth barrier or the foundation of a building that supports such a soil wall, or to prevent a boric system from danger.

In general, in order to build a concrete structure on the ground, it is necessary to construct a basement layer that is the basis of the structure. To construct the basement layer, a retaining wall is first constructed in the basement to form an outer wall of the basement layer.

This retaining wall is a wall structure that resists earth pressure and prevents soil from collapsing. It is an anti-earth pressure structure that maintains stability by using the weight of the wall itself and the frictional force of the bottom surface, and the earth pressure acting on the wall and the load on the soil. It is designed to ensure the stability of the structural members and the stability of the whole wall to collapse or slide, subject to the bearing capacity of the ground.

Therefore, in order to install the retaining wall in the basement, digging the ground and placing the H-beam on the supporting part where the retaining wall is formed, and digging each ground horizontally while digging the ground of the secured area of the basement layer, prevents the collapse of the soil. After the earth wall is formed, the mold is fixed to the mold by maintaining a constant distance from the formwork, and then the concrete is poured between the earth wall and the formwork to form the retaining wall.

That is, digging the ground into the soil wall where the soil wall is formed, and striking the 'H' beams at regular intervals, and layering the timber horizontal beams for preventing soil between the 'H' beams and the beams of the pillars to prevent the outflow of soil. In addition, to constitute the outer wall of the concrete supporting the anti-soil wall. At this time, a locking plate is formed between the stacked horizontal beams and the beams, and fixed by inserting and fixing the fasteners having integrally formed fastening rings at the ends thereof, and fixing the formwork formed to the thickness of the concrete wall with a wire or an elongated spacer bar. do. The concrete wall is formed by filling the reinforcing bars and concrete mortar between the fixed earth wall and the formwork.

The fastener in the above form a fixed plate of a triangular or square body at the end of the ring is formed to enable the fastening plate of the tip between the horizontal beam and the spacing of the formwork and the supporting wire to fasten the hook of the fastener compared to the conventional convenience Although this is increasing, in such a configuration, there is the complexity of the worker cutting and fixing the thick wire (iron wire which is about 5 mm in diameter and the warpage is not good) according to the distance. In addition, there is a drawback of screw tightening when coupling with screws by forming an elongate fastening rod on the fixing plate.

In addition, as a means for fixing the formwork and the earth wall, the wood or the like is sandwiched between the formwork and the earth wall. However, when placing concrete between the formwork and the earth wall fixed by the fixing means as described above, due to the pressure of the concrete to be poured, the lumber loaded between the formwork and the earthen wall is pulled out or the formwork is pushed outward. As the thickness of the retaining wall is not constant and the filling phenomenon occurs, the outer surface of the retaining wall does not maintain a constant surface.

Various devices have been devised to solve the above problems. For example, Republic of Korea Utility Model Publication No. 20-1998-017205 forms a bolt coupler into which a fixing bolt is inserted to easily and firmly fix a tie bolt fixing the formwork to the retaining wall when placing the retaining wall. The formwork fixing tie bolt fastener which consists of a fastening part, the coupling part which formed the female screw, and the connection part which connects the said fixing part and the coupling part is introduced. However, the above design is simple in terms of construction, but when there is a lot of concrete pouring, there is a risk of full stomach. Also, Utility Model Registration No. 20-0157465 has a plurality of fastening holes and is fixed to the earth plate by fixing screws. A body consisting of a fixed surface to be fixed, an intermediate portion bent at right angles from one end of the fixing surface, a body bent at a right angle in the opposite direction to the fixing surface at the distal end of the intermediate portion, and comprising this perforated connection of the through hole, It introduces a formwork fixing earth plate anchor consisting of a nut that is welded in the state formed in the through hole formed and the tip of the anchor bolt is screwed. However, the anchor as described above is difficult to prevent the hungry phenomenon when placing a large amount of concrete, there is a disadvantage that it is difficult to control the thickness of the formwork when placing concrete.

In order to solve the above-mentioned problems, the present invention seeks to provide a formwork that can achieve a reduction in material costs and construction periods as well as a waterproofing problem and a reduction in construction risk by simplifying construction.

In order to achieve the above object, in the fixing device of the earth wall, a flange groove portion is formed so that one side of the flange portion of the horizontal H beam is inserted, and the other side of the first fixture and one side is formed with a plurality of first holes A second hole is formed so that the second hole is formed to be fastened and mounted through the first hole of the first fixture and the joint pin, and the second fixture is formed with a rectangular box into which the vertical H beam is inserted. It is slidably mounted to the H-beam provides a formwork for earth walls, characterized in that to cast concrete.
