As shown in Figures 2 and 3, the joist fastening device 1000 and the yoke fastening device 1000 of the present invention is opposed to the first fixing unit 110 formed to extend upwards so that the joist is placed, the first seating portion formed in a U-shaped ) And the second seating portion 210 which is fastened to the lower portion of the first seating portion 100 and is formed in a U-shape to face the second fixing stand 210 extending downward so that the yoke is fitted into the first seating portion 100. And a fastening member 300 for fastening the second seating part 200 to each other.

At this time, the first seating part 100 and the second seating part 200 are formed of elastic steel to support the load of the concrete and slab plywood, and to support the joists at the top and the joist at the bottom It will be fixed.

In addition, the risk of deformation and breakage of the joist and yoke fastening device 1000 is reduced to increase the recyclability, which has the effect of reducing the construction cost.

At this time, an end portion of the first fixing stand 110 of the first seating part 100 and an end portion of the second fixing stand 210 of the second seating part 200 are formed to be narrowed inwardly.

In other words, the end of the first fixing stand 110 and the end of the second fixing stand 210 formed to be narrowed inward are fixed due to the elastic force of the steel, and the first fixing stand 110 is in close contact with the joist, The second fixing stand 210 supports and fixes the yoke in close contact.

At this time, the joist and yoke fastening device 1000 is the first seating portion 100 is curved outwardly to the end of the first fixing rod 110 in order to conveniently and securely fasten the joist and the yoke The first curved portion 120 is formed to extend, and the second seating portion 200 is extended to the second curved portion 220 which is curved outward at the end of the second fixing stand 210.

In particular, the second curved portion 220 is double-curved inward and outward at the end of the second fixing stand 210 is formed to extend.

That is, the curved portion inwardly of the second curved portion 200 is fixed in close contact with the side of the yoke to support the weight of the yoke, and to prevent the yoke from being separated from the second seating portion 200. .

In other words, the yoke, which supports the load of the slab plywood and the joist and transfers the load to the copper bar, is mainly supported by the load and is fixed to be fitted rather than mounted on the contrary to the joist, The second curved portion 220 which is double curved inward and outward is formed in close contact with the side to support and fix the yoke.

On the other hand, when dismantling the ceiling formwork should be dismantled by cutting the joists from the bottom to the top, due to the difficulty of dismantling the joists and the stability of the worker, the first curved portion 120 is formed only the outer side curved portion. .

In addition, the first seating portion 100 and the second seating portion 200 is formed in a width in accordance with the uniform standard of the joist and yoke of the ceiling formwork for slab casting, the first fixture 110 and the first The two fixing station 210 also has a height that meets the uniform standards of the joist and the yoke.

Further, after the joist and the yoke are installed and fastened in a lattice direction through the joist and yoke fastening device 1000 according to the present invention, the joists and the yoke are horizontally aligned in the horizontal direction. At this time, in the ceiling formwork for slab casting, a height adjustable member such as U-HEAD JACK of the system club can be used.

As shown in FIG. 4, the joist and yoke fastening device 1000 according to the present invention includes a first hollow 130 formed at the center of the first seating part 100, and a center of the second seating part 200. A second hollow 230 is formed, through which the fastening member 300 fastens the first seating part 100 and the second seating part 200.

In particular, the fastening member 300 for fastening the first seating portion 100 and the second seating portion 200 of the joist fastening device 1000 is formed by riveting coupled to the rivet joint do.

In addition, the joist and yoke fastening device 1000 according to the present invention is formed to be freely rotatable of the first seating portion 100 and the second seating portion 200.

As shown in Figure 5, the joist and yoke fastening device 1000 of the present invention is that the fastening member 300 is loosely riveting the first seating portion 100 and the second seating portion 200 to each other In combination, it is possible to freely rotate depending on the position and the situation in which the fastening device is used.

That is, when the first seating part 100 and the second seating part 200 are freely rotated, the first seating part 100 is not used for fastening the joist and yoke of the ceiling formwork or for other purposes. And the second seating portion 200 are rotated in the same horizontal direction from the vertical direction to each other, to reduce the risk of deformation and destruction resulting from the instability in the vertical direction, the loading of the joist fastening device 1000 It has the advantage of improving ease and efficiency.

In other words, the joist and yoke fastening device 1000 according to the present invention can simplify the structure of the fastening device through free rotation, and recycle today in the convenience of loading and moving and reducing the travel time, reducing the risk of deformation and destruction It has the advantage of excellent properties.

The fastening member 300 for fastening the first seating portion 100 and the second seating portion 200 of the joist and yoke fastening device 1000 according to the present invention is another member other than a rivet coupled by rivet joints. It may be formed to include.

As shown in FIG. 6, the fastening member 300 is formed as a pin of a pincer shape, and fixes and fastens the first seating part 100 and the second seating part 200 by elasticity.

That is, the fastening member formed of the pin does not need the rotational capacity as opposed to the fastening member coupled to the rivet joint, there is no need to loosely rivet the rivet, there is an advantage that the fastening device is formed concisely.

In addition, the fastening and disassembly of the first seating part 100 and the second seating part 200 can be facilitated, thereby improving the loadability and mobility of the fastening device, which in turn improves the operator's efficiency and risks deformation and destruction. This has the advantage that the recyclability is further increased.

The present invention is not limited to the above-described embodiment, of course, the scope of application, of course, various modifications are possible without departing from the gist of the present invention claimed in the claims.
