Abstract
Description
Technical Field
[0001] This utility model relates to a hollow floor slab that is easy to assemble and disassemble, and mainly relates to the field of floor slab construction. Background Technology
[0002] In the construction of houses, core molds are used to reduce the weight of each floor. The core molds are supported by wire mesh on the concrete base, and concrete is poured between adjacent core molds so that all the arranged core molds can be poured together, making each floor hollow and reducing the transmission of sound between each floor.
[0003] The concrete base layer is constructed by first setting up a wire mesh, then placing the core mold on the wire mesh. Concrete is also poured over the wire mesh below the core mold. The lack of a defined position for the core mold leads to inconsistent thickness of the concrete pour below, affecting the overall quality. Utility Model Content
[0004] To address the shortcomings of the existing technology, this utility model proposes a hollow floor slab that is easy to assemble and disassemble. The bottom plate is part of the floor slab structure and does not need to be disassembled, making construction simpler. The concrete pouring thickness under the mold box is more uniform, significantly improving the overall construction quality.
[0005] To achieve the above objectives, the technical solution of this utility model is: including a base plate and a hollow mold box;
[0006] The base plate is made of concrete, and a positioning column is provided on the upward side of the base plate;
[0007] Hollow mold boxes are provided on both sides of the positioning post, and the side walls of the hollow mold boxes are provided with several side ears. The two ends of the long rod are respectively connected to the side ears of the hollow mold boxes on both sides of the same positioning post.
[0008] The hollow mold box is surrounded by several steel reinforcement frames.
[0009] The technical principle and beneficial effects of this utility model are as follows:
[0010] This solution uses positioning columns and long rods to bind the two hollow formwork boxes at a specific height, preventing them from floating upwards during concrete pouring. The positioning columns create gaps between the hollow formwork boxes, which can be used for venting. Concrete is poured from the outside of the two hollow formwork boxes, flowing towards the center, preventing voids in the middle. This makes the pouring process simpler, more reliable, and results in more consistent quality. The base slab, as part of the floor slab structure, does not need to be dismantled, simplifying construction. The concrete thickness under the formwork boxes is also more uniform, significantly improving the overall construction quality.
[0011] Preferably, the sidewalls of the positioning post are made of non-metallic material to avoid corrosion from contact with the hollow mold box.
[0012] Preferably, the inner sides of the hollow mold boxes on both sides of the same positioning post are provided with grooves corresponding to the positioning post. The grooves provide better locking to the positioning post and prevent wobbling.
[0013] Preferably, an venting gap is provided between the hollow mold boxes on both sides of the same positioning column. This facilitates venting during casting and prevents the formation of voids.
[0014] Preferably, the base plate has a plurality of reinforcing bars extending upwards and connected to the reinforcing steel skeleton. This facilitates better structural integration with the poured concrete.
[0015] Preferably, the hollow mold box is made of stainless steel. This provides higher strength, greater durability, and better corrosion resistance in the anaerobic environment of concrete.
[0016] Preferably, a gap is left between the hollow mold box and the reinforcing steel frame and the reinforcing steel rods to avoid mutual contact and corrosion.
[0017] Preferably, a desiccant is placed inside the hollow mold box to prevent corrosion caused by water inside. Attached Figure Description

[0022] Example
[0023] like Figure 1 As shown, this embodiment of the utility model includes a base plate 1 and a hollow mold box 2;
[0024] The base plate 1 is made of concrete, and a positioning column 3 is provided on the base plate 1.
[0025] Hollow mold boxes 2 are respectively provided on both sides of the positioning post 3. Several side ears 4 are provided on the side wall of the hollow mold box 2. The two ends of the long rod 5 are respectively connected to the side ears 4 of the hollow mold box 2 on both sides of the same positioning post 3.
[0026] The hollow mold box 2 has several steel reinforcement frames distributed around its perimeter.
[0027] The technical principle and beneficial effects of this utility model are as follows:
[0028] This design uses positioning columns 3 and long rods 5 to bind the two hollow mold boxes 2 at a specific height on the positioning columns 3, preventing them from floating upwards during concrete pouring. Furthermore, the positioning columns 3 create gaps between the hollow mold boxes, which can be used for venting. Concrete is poured from the outside of the two hollow mold boxes 2, flowing towards the center, preventing voids from forming in the middle. This makes the pouring process simpler, more reliable, and results in more stable quality. The base slab 1, as part of the floor slab structure, does not need to be dismantled, further simplifying construction.
[0029] The sidewalls of the positioning post 3 are made of non-metallic material to prevent corrosion from contact with the hollow mold box 2.
[0030] The inner sides of the hollow mold boxes 2 on both sides of the same positioning post 3 are provided with grooves corresponding to the positioning post 3. The grooves can better lock the positioning post 3 and prevent shaking.
[0031] A venting gap is provided between the hollow mold boxes 2 on both sides of the same positioning column 3. This facilitates venting during pouring and prevents the formation of voids.
[0032] The base plate 1 has several reinforcing bars extending upwards and connected to the reinforcing steel frame. This facilitates better structural integration with the poured concrete.
[0033] The hollow mold box 2 is made of stainless steel. It has higher strength, is more durable, and is more corrosion-resistant in the anaerobic environment of concrete.
[0034] A gap is left between the hollow mold box 2 and the steel reinforcement frame and the steel bars to prevent mutual contact and corrosion.
[0035] A desiccant is placed inside the hollow mold box 2 to prevent corrosion caused by water inside.
