Description

[Detailed explanation of the invention] Concrete structures whose surfaces are designed to express masonry patterns of natural stones, colors and patterns that are in harmony with the natural environment such as bamboo forests, or various concrete surfaces of general buildings in urban areas. When constructing a concrete structure in which various patterns, plastic arts, etc. have been transferred and molded, conventionally, the mat on which the various patterns, plastic arts, etc. are to be molded is attached to the concrete surface of the inner surface of the concrete form using an appropriate adhesive. However, since the concrete formwork breaks in a relatively short period of time, it is difficult to remove the pine from the concrete formwork, and the removed pine may also be damaged during the removal process. In many cases, it is not possible to paste it onto new concrete and use it again, which is extremely uneconomical, and a solution to this problem has been sought. The present invention provides an apparatus for constructing concrete structures that can solve the above-mentioned problems. Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 2 is a side view of the same, and FIG. 3 is a longitudinal sectional view thereof. The inside of the conical body 1 is formed into a hollow portion 2, and the upper end thereof is formed with an insertion hole 3. FIG. 4 is a perspective view of the fixing tool B, where 4 indicates the head and 5 indicates the fixing tool. Figure 5 is a side sectional view of the assembled concrete construction device C, where D is the mat, E is the concrete formwork, 6 is the separator, 7 is the push washer, 8 is the formwork tightening rod, and 9 is the nut. It shows. Figure 6 shows the insertion of the fixing material B into the insertion hole 3 of the crimping tool A.
FIG. 3 is a partial view showing a state in which the concrete formwork E is pressed against a mat D superposed on the concrete formwork E. FIG. 7 is a partial view showing a state in which the head 4 of the fixing tool B is hit with a hammer (not shown) or the like, and the mat D and the concrete form E are fixed together. That is, the crimping tool A is made of a material having plasticity, such as lead material, and is configured into a conical body 1 having a hollow part 2 inside, and a hole 3 through which the fastening tool B is inserted is bored at the top of the conical body 1. The concrete formwork E is inserted through the pine D into this insertion hole 3.
Insert the fastening tool B having the fastening part 5 that pierces the mat D, and hit the head facing the fastening part 5 with a hammer (not shown) or the like so that the crimping tool A becomes flat as shown in FIG. and concrete formwork E are fixed together. In other words, the concrete formwork with the mat attached is rotated several times during normal concrete work, and if the concrete formwork is damaged, a crowbar (not shown) is inserted between the flat crimping tool A and the mat D. Pry in the tip of the crimping tool A, lift the crimping tool A, and remove the fastening tool B from the concrete formwork E and mat D. This extraction work is performed using crimping tool A.
Since the crimping tool A is made of plastic material, it is possible to easily force a crowbar, etc., and in addition, the crimping tool A can be pushed up from the bottom of the head 4 of the crimping tool B, making it extremely easy and quick. This prevents the pine from being damaged or damaged, making it possible to reuse the pine. In addition, since the crimping tool A has a conical shape and a hollow part, it can be handled with a fingertip even though it is relatively small.After the mat D and the concrete formwork E are fixed together, the crimping tool A becomes flat. Since no convex part is formed on the upper surface of the mat D, no concave part is formed on the concrete surface after the concrete formwork E to which the mat D is fixed is peeled off after the concrete hardens, so that the concrete surface is in a state that is suitable for the purpose. It can be built with

As described above, the concrete structure construction device of the present invention is economically extremely useful, and has excellent handling and ease of use.
It is easy to work with, has great practicality, and has a wide range of applications and great effects.
