The present invention relates to a formwork spacing mechanism for building construction, and more particularly, to improve the existing spacing mechanism and to produce a plastic injection molded product inexpensive and easy to carry and transport with a low cost of plastic products in the production convenience In addition, the installation and dismantling work is carried out quickly by the rotation operation in use, and the work efficiency and workability and the time required for the work, such as to significantly reduce the efficiency of the product for the formwork gap maintenance mechanism.

In general, in constructing a concrete structure, the concrete structure is placed between the molds to be maintained at regular intervals, if cured, the form is separated and moved to the upper floor after separating the form to be tightened to maintain a constant interval again to repeat the method of placing concrete Perform the construction to construct the building. Such a formwork holds the inner and outer formwork so that the gap between a pair of foams (eurofoam and gangform) is not opened by the concrete load until curing is completed, and thus the concrete is fixed to be cured to a certain thickness. Space keeping mechanism is needed. In recent years, the gap maintenance mechanism has been steadily developed to shorten the construction period along with workability due to the installation and separation of formwork.

1 is a cross-sectional view showing a conventional formwork spacing mechanism.

Conventional formwork spacing mechanism is formed by forming a hole in the front end of the Sepha Tie 1, insert the edge pin (not shown) to be fixed to the formwork (4 '), the connecting rod (2) through the coupling hole (3) at the rear end ) Is mounted. The connecting rod (2) is fastened to the support plate ring (5a) and the wing nut (5) to the bolt portion (2a) formed at the other end through the support plate (not shown in the figure) with one end mounted on the coupler (3) Secure the formwork (4). Therefore, the connecting rods 2 stably maintain the spacing of the dies 4 and 4 'by tightening the wing nuts 5 exposed from the supporting plate.

Accordingly, when the concrete is poured between the molds 4 and 4 ', which are maintained at regular intervals by the Sepha Tie 1 and the connecting rods 2, the molds 4 and 4' are removed. The die 4 'is removed by removing an edge pin on the sepatie 1, and the die 4 separates the wing nut 5 fastened to the bolt portion 2a of the connecting rod 2 to support plate ring. Remove and disconnect 5a) and connecting rod (2).

On the other hand, if the formwork is installed up to six stages to the top, up to five stages using the Seper Tie (1), but instead of the Seper Tie in six stages are buried using the buried, and mounted in the same way. The anchor bolt is bent in close contact with the die (4 ') is embedded on the die (4'), is provided with a male screw on the rear end is screwed to the coupler (3).

However, in the conventional formwork spacing mechanism for the formwork (4) (4 ') during installation and dismantling of the wing nut (5) screwed to the bolt portion (2a) to rotate and loosen and tighten the work is inevitable, Considering the installation of thousands of pieces of work in the formwork (4, 4 '), installation and dismantling work is inferior in assemblability, time consuming, and delays in air, and this simple work is inconvenient for workers. There was a disadvantage in that workability and work efficiency were extremely reduced.

In addition, the fastening parts, such as the connecting rod (2) and the support plate ring (5a) and the wing nut (5), which maintain the spacing of the formwork (4, 4 ') are mostly made of steel, so the manufacturing cost is high and the processing cost is high. In addition, since the parts used in the first floor are separated again and used to be transported to the upper layer, the fastening parts are heavy and have a disadvantage in that transportation and transportation are inconvenient.

In addition, the connecting rod 2 that is not loosened when the formwork 4 is detached is forced to use a dedicated tool (not shown), such as a pipe wrench, and the bolt part 2a is damaged so that an accurate tightening is not performed. It is difficult to recycle and repeat use due to deformation due to bending, and eventually, the city park price is increased because the lost fastening parts must be repurchased.
