Description

Technical Field

[0001] This utility model relates to a composite slab, and more particularly to an improved reinforced concrete composite slab with steel truss. Background Technology

[0002] Reinforced concrete composite slabs are a type of building structure that combines the advantages of precast components and cast-in-place concrete, and are widely used in modern architecture. They consist mainly of two parts: a precast concrete slab at the bottom and a layer of concrete poured on-site at the top. These two parts are connected together by a steel truss (also known as a steel mesh or steel skeleton) to form a unified structure.

[0003] The integrity between composite slabs and between composite slabs and the steel reinforcement cages of beams is very important, as it directly affects the safety, stability, and durability of the building structure. Utility Model Content

[0004] The purpose of this utility model is to provide an improved reinforced concrete composite slab to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an improved reinforced concrete composite slab, comprising a precast layer, a baffle, a placement groove, a reinforced truss, protruding reinforcement, an integral reinforcing structure, a cast-in-place layer, a connecting plate, an interface, and fixing bolts. The baffle is installed around the top perimeter of the precast layer, the placement groove is distributed on the baffle, the reinforced truss is distributed at the top of the precast layer, the protruding reinforcement is distributed at the top of the precast layer through the placement groove, the integral reinforcing structure is placed at the top of the precast layer, the cast-in-place layer is set at the top of the precast layer, the connecting plate has interfaces on its left and right sides, and the fixing bolts are connected to the integral reinforcing structure through the interfaces.

[0006] Based on the above technical solution, the overall reinforcement structure includes a frame, fixing blocks, fixing columns, and threaded holes. The frame is placed inside the baffle through the top of the precast layer. The fixing blocks are distributed at the top of the frame, and the cast-in-place layer covers the frame and fixing blocks. The fixing columns are fixed at the four corners of the top of the frame, and the lower part of the fixing columns passes through the cast-in-place layer. The threaded holes are axially opened at the top of the fixing columns.

[0007] Based on the above technical solution, the fixing bolt connects the connecting plate to the threaded hole through the interface.

[0008] Compared with the prior art, the present invention has the following advantages: The present invention improves the safety, stability and durability of the building structure by installing an integral reinforcing structure inside the composite slab and cooperating with connecting plates to enhance the integrity between the composite slabs and between the composite slabs and the beams.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] like Figures 1 to 4 As shown, an improved reinforced concrete composite slab includes a precast layer 1, a baffle 2, a placement groove 3, a reinforced truss 4, protruding reinforcement 5, an integral reinforcing structure 6, a cast-in-place layer 7, a connecting plate 8, an interface 9, and fixing bolts 10. The baffle 2 is installed around the top perimeter of the precast layer 1. The placement groove 3 is distributed on the baffle 2. The reinforced truss 4 is distributed at the top of the precast layer 1. The protruding reinforcement 5 is distributed at the top of the precast layer 1 through the placement groove 3. The integral reinforcing structure 6 is placed at the top of the precast layer 1. The cast-in-place layer 7 is set at the top of the precast layer 1. The connecting plate 8 has interfaces 9 on its left and right sides. The fixing bolts 10 are connected to the integral reinforcing structure 6 through the interfaces 9.

[0016] The overall reinforcing structure 6 includes a frame 11, fixing blocks 12, fixing columns 13, and threaded holes 14. The frame 11 is placed inside the baffle 2 through the top of the precast layer 1. The fixing blocks 12 are distributed at the top of the frame 11, and the cast-in-place layer 7 covers the frame 11 and the fixing blocks 12. The fixing columns 13 are fixed at the four corners of the top of the frame 11, and the lower part of the fixing columns 13 passes through the cast-in-place layer 7.
