Generally, molds are used to construct walls, slabs and columns of concrete buildings. Recently, concrete structures are constructed by constructing molds with euro foam and gypsum.

When constructing such a concrete structure, slabs corresponding to the floor and ceiling of the room, and beams to support the slab between pillars and pillars during the construction of pillars and walls are to be constructed.

FIG. 1 is a typical state of the conventional concrete construction for constructing the slab supporting beam.

In Fig. 1, reference numeral 1 denotes a slab formwork, 2 denotes a formwork, 3 denotes a yoke, 4 denotes a shovel, and 5 denotes a shovel.

As shown in FIG. 1, the slab form 1 for constructing the slab is formed in the conventional slab form, and the slab form 1 is formed on the lower side of the slab form 1 with a plywood plate.

A yoke 3 is formed on the lower side of the bracket 2 to receive the bracket 2 and the yoke 3 is supported by the bracket 4 and the both sides of the bracket 2 Are formed by assembling a plurality of triangular-shaped holding zones (5).

However, in order to construct the beam as described above, it is required to support a certain height of the lower part of the formwork, and since the formwork is installed and fixed, the installation work is complicated and there is a risk of safety accident.

In addition, the construction and dismantling work is complicated because it is fixed by nails such as brackets and piles. In order to adjust the spacing of the brackets, it is necessary to align the spacing holes in the slabs with the holes in the formwork, In order to fix the retainer, it is necessary to fix the retainer at the lower side of the slab die with a pin, thereby reducing workability and requiring a large number of workers.

In order to solve such a problem, the present applicant has provided a spacer for utility model registration No. 436231.

The spacing retaining member may include a side tie formed with a fixing piece having a fixing pin hole formed therein and an insertion piece formed with a fixing hole at an upper side of the other side thereof, and a vertical tie inserted into the insertion piece of the side tie, A middle tie having insertion holes formed at both ends thereof to be coupled to the middle tie, and a separation prevention pin inserted into the separation preventing hole formed in the insertion piece of the side tie inserted into the middle tie.

However, the above-mentioned gap maintaining tool for a bracket has a problem that a large amount of material enters by inserting the insertion piece of the side tie into the insertion hole of the middle tie and forming the insertion piece on the side tie and extending the middle tie.

In addition, since all of the release preventing pins are used on both sides, there is a problem that the number of parts increases, the productivity is lowered, and the assemblability is lowered.

In addition, since the central axes of the forces acting on the side tie and the middle tie do not coincide with each other, there is a problem that the tensile strength with which the side tie including the V cutting groove processed for removing the form fixing portion after the concrete curing is lowered.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a middle tie of a gap retaining groove for retaining a gap of a tie plate, It is possible to reduce the material by shortening the length and by combining the pair of left and right side ties with the middle tie symmetrically so that the force (side pressure) generated when the concrete is pushed acts on the middle tie and the side tie. The present invention is to provide a gap maintaining tool having a tensile force maximally increased by matching a working direction with a central axis.

Still another object of the present invention is to fix the side tie and the middle tie in the middle tie by forming a fixing groove in the middle tie and inserting the side tie into the side tie and fixing the side tie and the middle tie.

This is intended to reduce the number of parts required to prevent escape of ties, thereby improving productivity and workability.

According to an aspect of the present invention, there is provided a method of manufacturing a semiconductor device, including a pair of side ties each having a fixed piece formed with an extended fixed pin hole at one end thereof, a fixing hole formed at the other side thereof, A middle tie in which fixing grooves are formed on the upper or both ends of the upper and lower ends of the both ends so as to be inserted and fixed in the fixing holes of the side tie and the locking tongues and the separation preventing holes are formed at one or both ends of the fixing groove To provide a space-retaining aperture for the formwork.

And the outer end surface of the one end of the middle tie and the upper end of the fixing groove, which are staggered at the upper and lower sides of the tongue, are inclined outward by 5 °.

As described above, the present invention can reduce the material by changing the structure of the side tie and the middle tie, and combine the left and right side tie and the middle tie symmetrically to create a force (side pressure) When acting on the middle tie and the side tie, the force acting direction and the central axis coincide with each other, so that the tensile force can be increased as much as possible.

In addition, when a fixing groove is formed in the middle tie so as to be inserted into the side tie, and the side tie and the middle tie are fixed, it is unnecessary or less necessary to reduce the number of parts, thereby improving the productivity and workability.
