Description

Technical Field

[0001] This utility model relates to a placement structure for steel truss floor decking, belonging to the field of building construction technology. Background Technology

[0002] When steel truss floor decks are installed on pre-formed beams, the spacing between the ends of the steel truss floor decks must be ensured (see Chinese Patent Publication No. CN211421540U) so that the subsequently poured concrete can flow into the spacing between the ends of the steel truss floor decks to form the concrete.

[0003] After the steel truss floor deck is placed on the beam, its position is adjusted. However, due to the large weight of the steel truss floor deck, it is inconvenient to adjust its displacement by friction after it comes into contact with the beam. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a placement structure for steel truss floor decking.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a placement structure for a steel truss floor deck, comprising: Floor decking with mounting holes; The beam is used for hoisting and lowering the floor decking for installation. Alignment screws are pre-embedded and fixed on the beam. The floor decking is provided with mounting holes with a diameter larger than that of the alignment screws.

[0007] The floor deck is a concrete slab; the mounting holes are four holes distributed at the four corners of the floor deck.

[0008] A steel truss is fixed to the top surface of the floor deck.

[0009] The mounting hole is divided into a straight section and a tapered section, and the alignment screw is only located within the straight section.

[0010] It also includes a guide rod that can be screwed into the alignment screw through a threaded pair. The guide rod is smaller than the mounting hole, so that there is a gap between the guide rod and the mounting hole. The guide rod has an external thread, and a downward pressure cone is slidably sleeved on the outside of the guide rod. A nut is fixed on the downward pressure cone. The nut has an internal threaded hole that engages with the external thread of the guide rod through a threaded pair.

[0011] The bottom of the guide rod is provided with an internal threaded hole to achieve a detachable connection with the external thread of the alignment screw through thread engagement.

[0012] The guide rod, the pressure cone, and the nut are used in two sets at an angle.

[0013] The beneficial effects of this utility model are as follows: When the floor decking is hoisted above the beam, the mating hole of the floor decking is inserted into the alignment screw on the beam. At this time, there is a gap between the alignment screw and the mating hole, and there is a small gap between the bottom surface of the floor decking and the top surface of the beam. The guide rod and the external thread of the alignment screw are engaged through the thread pair. At this time, the guide rod also has a gap with the mating hole. The nut is screwed downwards with the guide rod. The nut pushes down the cone to move downwards. During the process of engaging with the cone section, the floor decking is guided to be lowered and installed into contact with the beam. This ensures that the position of the floor decking hoisted and installed on the beam is the designed position, avoiding the problem of inconvenience in frictional movement and displacement adjustment when the steel truss floor decking is placed on the beam as a whole.

Detailed Implementation

[0015] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0016] like Figures 1 to 2 As shown.

[0017] This application discloses a structure for placing a reinforced steel truss floor slab, comprising: The top surface has a steel truss body 11 and a floor deck 1, which is a concrete slab.

[0018] A beam 2 is provided for hoisting and lowering the floor deck 1 for installation. Alignment screws 21 are pre-embedded and fixed on the beam 2. The floor deck 1 is provided with a mounting hole 12 with a diameter larger than that of the alignment screws 21. The mounting hole 12 is divided into a straight section 121 and a tapered section 122. The alignment screws 21 are only located in the straight section 121.

[0019] It also includes a guide rod 3 that can be screwed into the alignment screw 21 via a threaded pair. The bottom of the guide rod 3 is provided with an internal threaded hole to achieve a detachable connection with the external thread of the alignment screw 21 via a threaded pair.

[0020] The guide rod 3 has an external thread, and a downward pressing cone 31 is slidably sleeved on the outside of the guide rod 3. A nut 32 is fixed on the downward pressing cone 31. The nut 32 has an internal threaded hole that engages with the external thread of the guide rod 3 through a threaded pair. When the guide rod 3 is engaged, the nut 32 pushes the downward pressing cone 31 to move downward, so that the downward pressing cone 31 fits into the tapered section 122, allowing the floor deck 1 to be lowered and installed to contact the beam 2.

[0021] The process is as follows: the floor deck 1 is hoisted above the beam 2, and the mating hole 12 of the floor deck 1 is inserted into the alignment screw 21 on the beam 2. At this time, there is a gap between the alignment screw 21 and the mating hole 12, and there is a small gap between the bottom surface of the floor deck 1 and the top surface of the beam 2. The guide rod 3 and the external thread of the alignment screw 21 are screwed together through the thread pair. At this time, the guide rod 3 also has a gap with the mating hole 12. The nut 32 is screwed down with the guide rod 3. The nut 32 pushes down the cone 31 to move downward. During the process of the cone 31 engaging with the conical section 122, the floor deck 1 is guided to be lowered and installed into contact with the beam 2. This ensures that the position of the floor deck 1 hoisted and lowered into the beam 2 is the designed position, avoiding the problem of inconvenience in frictional movement and displacement adjustment when the entire steel truss floor deck is placed on the beam.

[0022] After the floor deck 1 is installed and contacts the beam 2, the nut 32, along with the downward pressing cone 31, screws upward on the guide rod 3. The guide rod 3 and the alignment screw 21 are loosened and disassembled. The steel reinforcement is connected to the steel truss body 11 on the floor deck 1. After the concrete is poured on site and solidified, the mounting hole 12 is sealed.

[0023] The mounting holes 12 are distributed at four corners of the floor deck 1. The guide rod 3, the pressing cone 31, and the nut 32 can be in two sets, which are used diagonally opposite each other.
