The hole is connected to the steel backing plate flexibly. The steel support includes the vertical reinforcement of the formwork, the upper chord reinforcement, a set of two lower chord reinforcements, the formwork horizontal reinforcement and the abdominal reinforcement. The lower chord reinforcement is connected by the formwork horizontal reinforcement, and the lower chord reinforcement is parallel to the upper chord reinforcement. The two ends of the upper chord reinforcement are respectively connected to the top of the vertical reinforcement of the formwork, the upper steel plate is located between the upper chord reinforcement, the lower chord reinforcement and the horizontal reinforcement of the formwork, and the steel backing plate and the upper steel plate pass through the bolt holes and tighten The bolts clamp and fix the reinforcement bracket up and down, and several steel backing plates are connected through the reinforcement bracket.

Preferably, the bottom mold is made of galvanized steel sheet.

Preferably, the bottom mold has a width of 600 mm or 576 mm and a thickness of 0.5 mm.

Preferably, the embossing is strip-shaped, and the embossing length is 100mm, the width is 10mm, and the distance between adjacent embossings in each group is 50mm.

The beneficial effects of the utility model are manifested in:

The utility model provides bolt through holes on the bottom mold, the steel backing plate and the upper steel plate, the bottom mold and the steel backing plate are movably connected through the bolt through holes and the bolts, and the steel backing plate and the upper steel plate are moved through the bolt through holes and the bolts. Connect and clamp and fix the steel bar bracket between the two, form a whole through multi-point connection and fixation, then pour concrete, after it is formed and solidified, just remove the bottom mold. The utility model has simple structure, is easy to manufacture, and has low cost , strong practicability, safe and reliable, easy to disassemble by hand, materials can be reused, can be assembled and lengthened, and are suitable for lifting prefabricated panels of various sizes.

detailed description

In order to further describe the utility model, it will be further described below in conjunction with the accompanying drawings.

As shown in Fig. 1-3, a detachable special device for lifting trusses without steel bars, including a base form 1 and a number of elongated steel backing plates 2 arranged above the base form 1, a number of steel bar supports 3 and a number of The upper steel plate 4, the bottom surface of the bottom mold 1 away from the steel backing plate 2 are provided with several groups of vertically arranged embossings 11, the bottom mold 1, the steel backing plate 2 and the upper steel plate 4 are provided with bolt through holes, and the bottom mold 1 passes through Bolts and bolt through holes are movably connected with the steel backing plate 2, and the reinforcement support 3 includes the vertical reinforcement 31 of the formwork, the upper chord reinforcement 32, a group of two lower chord reinforcements 33, the formwork horizontal reinforcement 34 and the abdominal reinforcement 35, and the lower chord reinforcement 33 passes through The formwork horizontal reinforcement 34 is connected, the lower chord reinforcement 33 is arranged in parallel with the upper chord reinforcement 32, and is connected through the abdominal reinforcement 35, the two ends of the upper chord reinforcement 32 are respectively connected with the top of the support formwork vertical reinforcement 31, and the upper steel plate 4 is located between the upper chord reinforcement 32 and the lower chord reinforcement 32 And between the horizontal ribs 34 of the formwork, and the steel backing plate 2 and the upper steel plate 4 clamp and fix the steel bar support 3 up and down through the bolt through holes and the tightened bolts, and several steel backing plates 2 are connected by the steel bar support 3 .

In order to further optimize the technical solution, the bottom mold 1 is made of galvanized steel sheet. The bottom mold 1 has a width of 600mm or 576mm and a thickness of 0.5mm. The embossings 11 are strip-shaped, and the length of the embossings 11 is 100 mm, the width is 10 mm, and the distance between adjacent embossings 11 in each group is 50 mm.

The utility model proposes a special lifting device for a detachable non-reinforced truss. With the help of the steel backing plate 2 and the upper steel plate 4, the two parts of the steel support 3 and the bottom mold 1 are firmly connected into a whole through the connecting bolts, ensuring The reinforcement support 3 and the bottom form 1 do not slip during transportation and hoisting, and the concrete is poured later. After it is formed and solidified, the bottom form 1 is removed by unscrewing the bolts.
