Detailed Description

Example one

As shown in fig. 1-5, a connecting piece for a bottom die-removal-free steel bar truss floor support plate, the connecting piece 2 comprises a bottom plate, and the top surface of the bottom plate is connected with at least one strip-shaped plate; at least one group of buckle units 27 are arranged on the strip-shaped plate, each buckle unit 27 comprises two L-shaped clamping grooves 23 which are arranged in the same direction, and a clamping hook 26 is formed between each clamping groove 23 and the upper edge of the strip-shaped plate. The snap unit 27 is used for connecting the lower chord of the steel bar truss.

The bottom plate is also provided with a second through hole 28, and the extended edge at any side of the second through hole 28 is bent downwards to form the supporting leg 24. Support legs 24 are vertically connected to the base plate and support legs 24 may be anywhere below the base plate.

The closed end of the clamping groove 23 is arc-shaped, the diameter of the arc is the same as that of the lower chord rib, and the structure is stable after the clamping groove is matched with the lower chord rib.

When the connecting piece is U-shaped, the lower edges of the two strip-shaped plates are respectively connected with the bottom plate; when the connecting piece is L-shaped, the lower edge of one strip-shaped plate is connected with the bottom plate.

The strip-shaped plate is also provided with a plurality of side holes 21, and part of the side holes 21 are embedded in the floor bearing plate. The length of the hook 26 is larger than the diameter of the lower chord of the steel bar truss, so that the hook 26 can fix the lower chord.

In this embodiment, the connecting piece 2 can be in a U shape, and the strip-shaped plate of the connecting piece 2 is provided with a plurality of clamping grooves 23 in an L shape, so that more connecting points can be provided, and the stability is improved. Together with the length of the hooks 26 and the rounded shape of the closed end of the slots 23, this arrangement provides a very good locking of the bars. Together with the first through-hole 22 and the side-hole 21, can be covered by the base of the deck plate, so that the connector has better adhesion with the deck plate. Simultaneously because supporting leg 24's effect makes and has remain certain space between the lower bottom surface of connecting piece 2 and building carrier plate, is adding supporting leg 24 and being connected with the building carrier plate for the structure is more stable, has strengthened the bearing capacity of building carrier plate.

Example two

As shown in fig. 1-5, the bottom plate is further provided with a plurality of first through holes 22, a small number of the first through holes 22 can be connected with the support bolts 1, and the first through holes 22 are embedded in the floor deck along with the bottom plate. The end part of the strip-shaped plate is also provided with a connecting hole 29, and the connecting hole 29 is connected with the connecting hole 29 of another connecting piece through a connecting plate 25 and/or a bolt to complete the splicing of the floor bearing plates.

In this embodiment, the connecting piece 2 is L-shaped, does not have supporting legs 24, and contains a plurality of first through holes 22, and a small amount of first through holes 22 are connected with supporting bolt 1, and supporting bolt 1 bottom is equipped with cushion 4. In the manufacturing process, the bottom plate is embedded in the floor bearing plate which is not solidified, so that the bottom plate and the floor bearing plate form a firm connecting structure, and the stress concentration phenomenon is eliminated. Meanwhile, due to the action of the cushion block 4, a certain space is reserved between the connecting piece 2 and the floor support plate, and meanwhile, the supporting bolt 1 is connected with a solidified substrate, so that the structural stability is enhanced.
