Description

Rebar Fixtures {steel reinforcement fixture}

The present invention relates to a reinforcing bar fixture, and more specifically, consisting of the upper and lower fixing body is configured to be arranged and fixed in the cross shape of the reinforcement, reinforcing steel fasteners that can be firmly fixed without performing a separate fixing operation It is about.

In general, when placing a concrete structure when constructing a building, first install the reinforcing bars according to the form of the building, and then install the concrete using formwork to install reinforcing bars inside the concrete structure. Will be done.

In other words, when placing a concrete building, first, the reinforcing bar is constructed in a bundle method according to the shape of the building, and then the concrete is laid by using formwork, and the reinforcing bar is embedded in the concrete structure.

However, the conventional reinforcing bar structure fixing method is a method of fixing the intersection of the reinforcing bars by using a wire and a separate dedicated tool to fix the difficult and difficult problem according to the fixing work as well as a lot of work time There is a problem such as that required.

Thus, Korean Patent Laid-Open Publication No. 10-2010-0098946, in the reinforcing bar fixing device to form a lower reinforcing bar support on one side of the inverted U-shaped plate, by removing the upper ceiling portion of the lower reinforcing bar support formed on the one side The lower reinforcing bar support part is composed of an open-air lower reinforcing bar support part which is open to the upper side, and a rebar fixing device in which a second lower reinforcing bar support part is formed on the opposite sidewall of the open lower reinforcing bar support part has been posted.

However, after the process of inserting the reinforcing bar downward from the top at a position slightly away from the rebar crossing part, the rebar fixing device is forcibly pushed toward the reinforcing bar so that the outdoor reinforcing bar supporting part supports the lower reinforcing bar. There is a hassle that has to go through a double process to be, accordingly, there is a problem that the construction time for fixing the rebar is long.

In addition, the Republic of Korea Utility Model Registration No. 20-0168575, it is composed of a fixing part for fixing the reinforcing bar, and a support leg for maintaining a constant distance between the reinforcing bar and the slab, the elastic piece on both sides of the fixing part at a certain interval Each end is formed so that the front end is outward, and a support for supporting the elastic piece and the reinforcing bars is formed, and the support leg is formed at the lower side of the fixing part, and connected to the support and formed with the support leg. Rebar fasteners for construction, characterized in that configured to form has been published.

However, the rebar fastener for construction according to the prior art described above does not provide a fixing force for the reinforcing bar when the elastic piece is damaged by the pressure applied when the rebar is fixed, so that the rebar arrangement is randomly changed when the concrete is placed. In addition to the separate work for this work is not only a significant decrease in the efficiency of the work, but also the fixing of the rebar in one direction only, cross-crossing in the cross shape is not possible to cross the arrangement and fixation of the rebar There is a problem that the bundle must be accompanied using a wire (bond line) as in the general method.

Republic of Korea Patent Publication No. 10-2010-0098946 Korea Utility Model Registration No. 20-0168575

In order to solve such a problem, the present invention is devised by the above-described background, and is composed of the upper and lower fixing body is configured to be arranged and fixed in the cross shape of the reinforcement, even if no additional fixing work The purpose of the present invention is to provide a reinforcing bar that can be firmly fixed.

In addition, the present invention can be secured even when the reinforcement of the concrete is made when the reinforcement is fixed so that the concrete can be carried out more quickly to perform the concrete placing process can significantly shorten the work time, placement and fixing the reinforcement The purpose is to provide a reinforcing bar fixture that can reduce the cost required for.

However, the object of the present invention is not limited to this, and even if not explicitly mentioned, the object or effect that can be grasped from the solution means or embodiment of the problem is of course included.

1 to 5 is a view showing a reinforcing bar fixture according to a first embodiment of the present invention, each consisting of a lower fixture 100 and an upper fixture 200 made of unit blocks.

The lower fixture 100 is configured so that the outer surface has a predetermined curvature and arc, the lower reinforcing bar fixing portion 102 and the lower reinforcing bar fixing portion 102 is configured to insert and fix the rebar with a predetermined elastic force It is integrally formed in, and seated on the floor of the building, and consists of a lower support portion 104 for supporting a predetermined distance between the reinforcing bar and the floor of the building.

In addition, the lower fastener 100 is composed of two, the first reinforcing bar 10 is configured to be inserted and fixed, the two lower fasteners 100 may be made of an independent unit block, or may be configured integrally.

Here, the lower reinforcing bar fixing portion 102 is formed to be opened to the upper center of the reinforcing bar insertion hole 140 is formed so that the insertion of the first reinforcing bar 10 is formed, predetermined to both sides of the reinforcing bar insertion hole 140 It comprises a first lower tension portion 110 and the second lower tension portion 130 is configured to be inserted and fixed to the first reinforcement 10 by the elastic force of the.

The first lower tension unit 110 is formed at one side about the reinforcing bar insertion hole 140, and when the first reinforcing bar 10 is inserted through the reinforcing bar insertion hole 140, the first reinforcing bar 10 is provided. Lower elastic support panel 120 that provides a predetermined elastic force toward the side is formed to extend to the central end portion.

In addition, the first lower tension unit 110 may be elastically operated in a direction perpendicular to the direction in which the first reinforcing bar 10 is inserted, depending on whether the lower elastic support panel 120 is inserted into the first reinforcing bar 10. Lower tension holes 112 are formed to penetrate in the front and rear directions.

That is, the first reinforcing bar 10 is inserted from the top to the bottom, and the lower elastic support panel 120 is elastically operated in the left and right directions, which are perpendicular to the outer peripheral surface of the first reinforcing bar 10 It is configured to always keep in close contact with.

At this time, the lower elastic support panel 120 is formed to be inclined toward the second lower tension portion 130 from the end of the first lower tension portion 110, the end portion of the second lower tension portion 130 And coaxial with.

As a result, the first reinforcing bar 10 inserted into the reinforcing rod insertion hole 140 comes into contact with the lower elastic support panel 120. Then, when the first reinforcing bar 10 is pressed from the outside, the lower elastic supporting panel 120 is pressed. The elastic reinforcement of the reinforcing rod insertion hole 140 toward the lower tension hole 112 is made while the diameter of the reinforcing hole 140 becomes wider, and at the same time, the first reinforcing bar 10 The first rebar 10 may be fixed to the rebar fixing hole 150 by moving to the rebar fixing hole 150 formed in the lower tension unit 130.

In addition, since the lower elastic support panel 120 maintains a state of being always in close contact with the outer circumferential surface of the first reinforcing bar 10, the first reinforcing bar 10 inserted and fixed in the reinforcing bar fixing hole 150 is arbitrarily selected. Deviation will not be made will be easier to pour concrete.

The second lower tension portion 130 is formed on the other side of the reinforcing bar insertion hole 140, and is formed at a position opposite to the first lower tension portion 110 to insert the first reinforcing rod 10.
