According to the third embodiment of the present invention, in addition to the above-described configuration, the support parts 112 and 122 are formed at the upper end of the support parts 112b and 122b; Although not shown in the drawing, a balance sign with the side plate) is formed, and the structure in which the end portions 112a and 122a are rolled so as to form an arc at the end facing downward is the same as described above.

According to the fourth embodiment of the present invention, in addition to the above-described configuration, a portion of the upper end of the rear plate 12 of the main body 1 is pierced so that the upper portion forms the same surface as the rear plate 12 and the lower portion is cut open. A clasp 124 protruding toward the side is formed, or a clip (not shown) formed by bending a wire or formed of resin is installed so that the reinforcing bars 411 and 421 installed on the seating portions 111 and 121 are not separated.

The installation state of the present invention, which is shown in FIG. 5, the installation state of the present invention, FIG. 6, and the partially broken perspective view of the conventional reinforced concrete structure of FIG. To explain.

According to one configuration of the present invention, the spacer of the present invention consists of a main body 1 which is made of one material, and the main body 1 has a side plate 11 and a back plate 12 formed of one material and extends to an angle shape. Since the structure is formed by bending and bending a thin plate, it is suitable for mass production by press working or the like.

In addition, the side plate 11 and the back plate 12 is formed with seating portions 111 and 121 which are recessed at the upper end, respectively, in a position perpendicular to each other such that the side plate 11 and the back plate 12 form an angle, for example, When the reinforcing bars 411 or 421 are placed horizontally on the seating portion 111 of the side plate 11 and the reinforcing bars 411 or 421 are placed vertically on the seating portions 121 of the rear plate 12, the lattice rebar 40 ) Orthogonal to each other between the reinforcing bars (411 or 421) forming a) by simply placing the reinforcing bars (411 or 421) horizontally and vertically on the spacer of the present invention to complete the setting in the correct position to ensure fast / convenience and secure positioning It can be achieved.

In addition, the seating portions 111 and 121 may be horizontally formed with a height difference of the thickness of the reinforcing bars 411 or 421 so that the horizontal and vertical reinforcing bars 411 or 421 constituting the lattice rebars 40 to be placed thereon may be properly placed. And vertical reinforcing bars 411 or 421 are supported by separate seating portions 111 and 121, respectively, so that the distribution of loads can be made appropriately, and bead (reinforcement) in the lower portion of the seating portions 111 and 121 for reinforcement. When the reinforcing portions 115 and 125, such as beads, are installed, even when the thickness of the plate is thin, the reinforcing bars 411 and 421 may be sufficiently supported without being broken or crushed when placed.

In addition, the support portions 112 and 122 are formed integrally with the end portions 112a and 122a protruding from the side plate 11 and the back plate 12 so that the ends directed downward are rolled to form an arc. The 112 and 122 secure the predetermined interval while supporting the main body 1, and can also function as reinforcement portions. In particular, the end portions 112a and 122a are formed by rolling the ends in a semicircle to form a slab ( The area exposed to the surface of S) is minimized. For example, if the material is made of galvanized metal, the exposed part is spherical, so that the rust prevention is made more complete, and the material is bare. Even when zinc is applied to the metal, the exposed part is not an edge but a cotton part, so there is no abnormality in rust prevention. The concern is less.

Moreover, when the blocking plate 13 which is bent and extended slightly in the side plate 11 or the back plate 12 or both of the main bodies 1 on the channel is formed, the angled main bodies 1 become quadrangular and the strength is increased. It is preferable to improve the shape, and it is preferable to form a recess part 113 and 123 by cutting a part of the lower end of the side plate 11, which solidifies the main body 1 by solidifying the poured concrete as one part in this part. Will come to an end.

According to another configuration of the present invention, the same configuration as described above, the main body 1 is attached to the two side plates (11, 11) on both sides of the back plate 12, the only difference that extends over the channel as a whole, which is the channel It is natural that it is convenient to install by standing up than the above configuration, and achieve a robust structure.

 In addition, the support part 112 maintains a predetermined interval while supporting the main body 1, but since the main body 1 is formed of a thin plate, the side plates 11 contacting the opening side are connected to both side plates 11 and 11. The support strength is lower than that of the back plate 12, and if the support portion 112 is formed on the side plate 11 side, it can contribute to the improvement of the support strength. If the interval between 112 is not appropriate, it is preferable to adjust the quantity in an appropriate amount because the rise of the road is not large.

According to still another configuration of the present invention, in addition to the above configuration, the support portions 112 and 122 form bending portions 112b and 122b which are bent and extended outward from the middle. In order to prevent it from falling easily due to being narrow, it is to bend the support parts 112 and 122 outward to widen the area occupied by the support parts 112 and 122. The forming of the 112b and 122b can be performed without any additional cost by forming the support parts 112 and 122 together when the press is processed, thereby bending the support parts 112 and 122 formed in the form of beads. The formation of the portions 112b and 122b is preferable because the bearing force can be increased to increase the structural load.

According to another configuration of the present invention, in addition to the above-described configuration, a portion of the upper end of the rear plate 12 of the main body 1 is pierced so that the upper portion forms the same surface as the rear plate 12 and the lower portion cut off toward the opening side. A protruding clasp 124 may be formed, which is pressed by the rebar 411 or 421 inserted into the concave inlet 123 and then depressed by pressing the rebar 411 or 421. When the clip (not shown) is installed, the reinforcing rods 411 and 421 installed on the seating portions 111 and 121 are wrapped around the outer circumference thereof so as to be supported by the main body 1. This can be adopted in the most common configuration, the ear canal is also for integrating the reinforcing bar (411 or 421) and the spacer body (1) so that the reinforcing bar (411 or 421) is not separated from the seating portion (111, 121).

As described above, the spacer according to the present invention is made of a metal in consideration of price and strength, but both of the above invention is to install the lower end standing on the formwork, when the formwork is removed to remove the formwork, the hem is exposed This invention is useful and effective to solve the problems of deterioration of durability due to corrosion, and to be applied to thin slabs as well as to solve problems such as installation convenience and inexpensiveness which were exposed in my prior application. to be.
