Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to the use of bar-shaped reinforcing bars for highways, reinforced concrete used in ordinary buildings, and buildings used for greenhouse horticulture such as greenhouses. The present invention relates to an intersection fixing device for rod-shaped bodies that connects and fixes intersections of tubular bodies, and a construction method using the same.

[Conventional technology] Conventionally, reinforcing bars used in reinforced concrete are:
For example, the tension main reinforcing bars and the distribution reinforcing bars are 35cm, 45cm,
Since they are tied using standardized iron wire such as 55C [O, etc., the tied part inevitably protrudes into the lifting force, and workers may get stuck on it while working, or they may get caught and trip over it, causing injury. This poses safety and fire hazards, and tools are required to tie the wire.
Furthermore, it requires experience.

In view of this, for example, a locking device disclosed in Japanese Utility Model Publication No. 52-54907 has been developed, which can be hung on and fixed at intersections. The aforementioned safety defects have been resolved, and
Is the work easy just by fitting the locking tool? In normal work of this type, the worker must sit on one of the reinforcing bars, or in this case, the worker sometimes has to fit the locking tool at the corner intersection. Even if the joints are joined together using steel wires or steel wires as described above, these joints will stretch due to the weight of the worker or the tools they are carrying, and the joints will not recover, causing the joints to loosen and cause the reinforcing steel structure to deteriorate. It has the following defects.

Furthermore, there is also a structure in which a pair of rod-like bodies intersect is fitted into a U-shaped wall formed of a plate material having a predetermined width, as disclosed in Japanese Utility Model Publication No. 55-11364. Although it is relatively easy to join, it is not actually used because it still has problems such as the concrete not entering inside when reinforced concrete is used, which causes strength problems.

Therefore, there is a need for a fixing device that can efficiently connect rods such as reinforcing bars and tubular bodies, that is safe, and that does not impair the adhesion strength to concrete, and for a construction method that uses this fixing device. There is.

[Problems to be solved by the invention] Conventional devices that connect the intersections of reinforced concrete reinforcing bars and pillars of buildings require experience and time to connect and fix. However, if a binding wire is used for joining, the knot may protrude and be dangerous to the worker.Furthermore, even if a binding wire or a locking device is used, there is a possibility that the worker may get on it during the work. There were various problems such as loosening and lowering the adhesion strength of concrete.

Therefore, the present invention can be easily fitted into the joints of rod-shaped or tubular bodies such as reinforcing bars, work can be done safely, and the cost can be reduced, and the fixed parts are joined with effective force, making it easy for workers to work. To provide an intersection fixing device that does not loosen even when a concrete member is placed on it, and does not reduce the adhesion strength of concrete when used as an auxiliary reinforcement for reinforced concrete, and a construction method using the same.

[Means for Solving the Problems] In order to achieve the above object, the first aspect of the present invention is to form rod-like bodies that face each other so as to form a narrowed part that can be placed in contact with the upper part of one of the intersecting rod-shaped bodies. A circular-arc-shaped support that includes a support part consisting of a pair of dogleg-shaped supports and a fulcrum part formed by connecting one end of these supports, and that allows the other rod-shaped body to be fitted facing the support parts. A pair of rod-shaped bodies are connected to each other by a connecting part so that the tip of the supporting part and one of the rod-shaped bodies can be inserted, and each of these parts is formed by bending a single elastic wire. The second part is a pair of rod-like bodies that face each other so as to form a constriction by abutting the intersecting part of the pair of rod-like bodies so as to be able to be stored in the upper part of one of the intersecting rod-like bodies. A pair of arc-shaped support parts, which are provided with a support part consisting of a dogleg-shaped support body and a fulcrum part formed by connecting one end of these supports, and which are opposed to the support part and into which the other rod-shaped body can be fitted. The distal end of the support part and the one rod-shaped body are connected by a connecting part that can be inserted through, and each of these parts is formed by bending a single elastic wire to fix the intersection part. The tool is inserted into one of the rod-shaped bodies through the supporting portion and the connecting portion thereof, and the pair of supporting portions are fitted onto the outer periphery of the other rod-shaped body, and then the fulcrum portion of the supporting portion is inserted into the one of the rod-shaped bodies. The rod-shaped body is placed in contact with the narrow part, and the rod-shaped body is held between the narrowed part and the rod-shaped body is urged toward the support part by the support part, so that the intersection of the pair of rod-shaped bodies is formed between the support part and the support part. This is a construction method that uses a rod-shaped intersecting fixing device that is clamped and tied together.

``Function'' The present invention, which is constructed by the above-mentioned means, has an intersection fixing device in which the α portion shown in FIG. When the pair of rod-shaped bodies intersect with each other, the support part has a biasing force for an angle smaller than the right angle and is fitted, so that the fulcrum part of the support part is attached to the upper outer periphery of the upper rod-shaped body as shown in Fig. 4. It is biased clockwise and comes into contact with the lower rod-shaped body so as to press it, and is placed in contact with the rod-shaped body arc so as to sandwich it in the narrowed part of the letter, and further The lower outer periphery of the lower rod-like body is held by the arc-shaped support, and the pair of rod-like bodies are firmly fixed by being biased and sandwiched between the support and the support.

Furthermore, when a worker stands on the lower rod-shaped body and puts his or her weight on it during work, the support part is pulled downward,
The narrowing portion is supported by a supporting portion via a connecting portion, or is formed entirely by bending an elastic wire, and the narrowing portion is formed by the supporting portion or a pair of dogleg-shaped supports, and Since the supporting part is provided with a fulcrum part and is biased so that the angle between the supporting part and the connecting part is slightly smaller than the right angle, the supporting part comes into contact with the upper part of one of the rod-shaped bodies at the fulcrum part and the narrow part. The lower rod-shaped body, which has once lowered due to the reaction force, is immediately urged to be pressed against the upper rod-shaped body, and is held securely in a fixed state.

[Example] In order to further clarify the gist of the present invention, an example will be described below using one drawing.

First of all, figure 1 or pJS3L! As shown in J, l is an intersection fixing device (hereinafter simply referred to as a fixing device), which connects the supporting portion 11, the supporting portion 12, and the connecting portion 13 by bending an elastic wire rod. The support portion 11 is formed by a pair of substantially doglegged supports 11a facing each other to form a narrowed portion 111a, and a fulcrum portion 11b formed by connecting one end of the narrowed portion 111a to form an intersecting point. The supporting portion 12 can be placed in contact with the upper side of one of the rod-like bodies, and at least the tip of the support body 11a has the outer diameter and width of the rod-like body, and the support portion 12 is It has a circular arc shape that faces the part 11 and can be fitted onto the other rod-shaped body, and has an arbitrarily curved opposite part 121 at the tip, and the other end and the support body The distal end of 11a is connected to the connecting portion 13.13, and the pair of connecting portions 13.1
The width between the support part 12 and the support part 12 is the same as or wider than the outer circumference of the upper rod-shaped body.
1 and the connecting portion 13 are formed at an angle of approximately 85°, which is slightly smaller than a right angle, so that when the supporting portion 11 is fitted to the pair of rod-shaped bodies, the supporting portion 11 is always biased with the fulcrum portion llb as the fulcrum. .
