Therefore, the present invention is always elastically supported in the binding direction by the torsion springs (32) and (32A) on both sides of the support upper plate (2) formed at the upper end of the support bar (1) is maintained in the unlocked state by the locking portion (5) A pair of fasteners 3 and 3A are symmetrically arranged on the hinge shafts 31 and 31A, and the pressure rod 41 is elastically supported by the spring 42 on the upper side of the support rod 1. The yoke supporting operation can be made more quickly and conveniently as well as the yoke supporting operation can be achieved by inserting the upper and lower slidably inserting parts and having a pair of pressing plates 43 and 44 formed on both sides thereof. There is an effect that can further increase the efficiency. In addition, there is an effect that can be firmly fixed and support the yoke so that the support rod is not moved or released even by the load and impact generated during the upper work or concrete pouring.

Description

Automatic yoke fastening device {Auto conclusive device of yoke bar for building}

The present invention relates to a building yoke automatic fastening device for automatically fastening the support bar used for the upper support when installing the floor slab formwork to the yoke bottom side.

In general, when the bottom slab formwork is installed, the support rod 100 as shown in FIG. 3 is used for the upper support, and the support upper plate 110 is formed on the upper side of the support rod 100 to form the yoke 120A Nailed into the nail).

However, this conventional construction yoke fastening method has a problem that often causes a safety accident by moving or detaching the support rod by the load and impact during the upper work or concrete pouring. Alternatively, when the yoke is fastened, the worker puts nails into the nail one by one, so that the work is not only cumbersome and inconvenient, but also takes a lot of work time, resulting in inefficiency of the work.

The present invention is devised to solve the conventional problems as described above, the purpose of the operation is made quickly and easily, the support rod is not moved or released even by the load and impact generated during the upper work or concrete pouring. So that the yoke can be firmly fixed and supported.

In order to achieve the object of the present invention, a pair of fasteners, which are elastically supported in the binding direction at all times by a torsion spring on both sides of the support upper plate formed at the upper end of the support bar, and maintained in the unlocked state by the locking part, are mutually connected to the hinge shaft. It is symmetrically constructed, the upper side of the support rod is a yoke automatic fastening device for the building yoke, characterized in that the pressing rod is elastically supported by the spring is inserted into the upper and lower slidably inserted and a pair of pressing plates formed on both sides thereof. Is provided.

In addition, the locking portion is characterized in that the locking grooves formed on both sides of the upper support plate of both sides of the fastener to lock the pins formed on both sides of the fastener to be fitted or released by rotation.

The pressure inclined surface is formed to be symmetrical with each other at the lower end of the pressing plate of the operating part, and the contact inclined surface and the supporting jaw in sliding contact with the pressure inclined surface are formed at the front end of the binding port.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration of the subject innovation.

1 is a perspective view showing the configuration of the present invention, as shown in the present invention is provided with a support rod 1 in the vertical direction as usual, and the yoke (not shown) on the upper end of the support rod 1 A rectangular support top plate 2 is formed to support the lower portion. In addition, a straight working space portion 20 is formed in the middle portion of the support upper plate 2, and a pair of fasteners 3 and 3A on both sides of the working space portion 20 are hinge shafts 31. ) Is rotatably arranged in (31A). In addition, a torsion spring, that is, a torsion spring 42, on which one end is fixed to the fasteners 3 and 3A on the outside of the hinge shafts 31 and 31A, and the other end is fixed to the support upper plate 2. ) Is elastically installed is configured to elastically support the binding port (3) (3A) in the normal binding direction.

And the locking portion (5) is provided so that the binding port (3) (3A) to maintain the disengagement state, the locking portion (5) is the support plate (2) on both sides of the binding port (3) (3A) Locking grooves 51 are formed at both inner side walls of the locking grooves, and the locking grooves 51 are fitted or fixed to the locking grooves 51 by rotation about the hinge shafts 31 and 31A on both sides of the binding holes 3 and 3A. The locking pin 52 is formed to protrude outward, wherein the locking pin 52 is forcibly held in the locking groove 51 and is fixed by a certain force, that is, a pressing force of the yoke (not shown). It is configured to be separated from the locking groove (51).

At the same time, the operating portion 4 is provided so that the fasteners 3 and 3A can be automatically operated by the pressing force of the yoke. The operating part 4 is formed to be slidably inserted into the upper and lower pressure rods 41 on the upper side of the support rod 1, the lower side thereof is elastically supported by a spring 42 embedded in the support rod (1) It is configured to be. In addition, a pair of pressing plates 43, 44 for pressing the binding ports 3, 3A directly on both sides of the pressure bar 41 is formed, the lower end of the pressure inclined surface 43A (44A) () Are formed symmetrically with each other.

Correspondingly, the contact inclined surfaces 34 and 34A in the same direction and the support projections 33 and 33A supporting the lower side of the yoke are formed to be symmetrical to each other at the distal end of the fasteners 3 and 3A.

Figure 2a and Figure 2b shows the operating state of the subject innovation, the subject innovation first, when pushed to the lower side of the yoke (120A) in a state as shown in Figure 2a, the pressure rod of the upper side of the support rod (1) The 41 is moved downward while overcoming the spring 42 elastic force in the support bar (1). Accordingly, the pressing plates 43 and 44 formed on both sides of the pressure bar 41 are also moved downward to press the binding ports 3 and 3A, and the binding ports 3 and 3A are pressed by the pressing force. Of the locking pin 52 is separated from the locking groove 51 and rotated in the binding direction about the hinge shafts 31 and 31A by the elastic force of the torsion springs 32 and 32A as shown in FIG. 2B. Yoke (120A) will be able to automatically bond with.

As described above, the present invention enables the automatic fastening to be made by the fastener without additional nailing, so that the yoke supporting work can be made more quickly and easily, and thus, the efficiency of the work can be further increased. have. In addition, there is an effect that can be firmly fixed and support the yoke so that the support rod is not moved or released even by the load and impact generated during the upper work or concrete pouring.
