Abstract
Description
Technical Field
[0001] This utility model relates to a gypsum box-assembled hollow floor slab, mainly in the field of hollow floor slabs. 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 gypsum board molded hollow floor slab, which avoids the hollow mold floating upwards after concrete pouring, and enables the hollow mold to be positioned, thereby improving the quality of construction.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows: it includes a column and two hollow mold boxes.
[0006] Two hollow molded boxes are respectively installed in the middle of both sides of the column.
[0007] The two hollow molded boxes are connected to each other by a pull rod, which pulls the two hollow molded boxes into and fixes them to the middle of the column;
[0008] The hollow mold box has several steel reinforcement frames and concrete distributed on its exterior.
[0009] The technical principle and beneficial effects of this utility model are as follows:
[0010] This design uses tie rods to fix two hollow formwork boxes to the middle of the column. This supports the hollow formwork boxes, preventing them from leaning too close together at the bottom and from floating upwards after concrete pouring. It also helps to position the hollow formwork boxes, improving construction quality. Furthermore, using two hollow formwork boxes together reduces the need for a large bottom area for each individual box. The gap between the two hollow formwork boxes serves as an air vent. When pouring concrete, it is poured from both sides, flowing towards the central gap, and then the central gap is filled, preventing voids from forming in the middle of the hollow formwork box.
[0011] Preferably, the column has a boss at its center that limits the lower position of the hollow mold box. This prevents the hollow mold box from sliding downwards on the column.
[0012] Preferably, the hollow mold box has side lugs on its side wall, and both ends of the pull rod are threadedly connected to the side lugs. Using side lugs facilitates fixing the pull rod to the pull rod.
[0013] Preferably, at least two columns are provided between the two hollow mold boxes to improve support strength and stability.
[0014] Preferably, the upper and lower ends of the column are fixed to the reinforcing steel frame. This allows the upper and lower ends of the column to be fixed when the wire mesh is tied, thus locking the position of the hollow formwork on the floor slab and making subsequent pouring more convenient.
[0015] Preferably, the outer wall of the column is made of a non-metallic material. The hollow mold box is made of stainless steel to prevent corrosion from contact with the hollow mold box.
[0016] Preferably, the column is made of precast concrete, which allows it to better integrate with the concrete floor slab to form a unified structure. Attached Figure Description
[0017] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only two of the drawings in this utility model. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

[0019] Figure 2 This is a top view of an embodiment of the present utility model.
[0020] Among them, template 1, hollow mold box 2, column 3, boss 4, and tie rod 5. Detailed Implementation
[0021] The technical solutions of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely preferred embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] Example
[0023] like Figure 1As shown, this utility model embodiment includes a column 3 and two hollow mold boxes 2. Two hollow mold boxes 2 are respectively arranged in the middle of both sides of the column 3. The two hollow mold boxes 2 are connected to each other by a tie rod 5. The tie rod 5 pulls the two hollow mold boxes 2 into and fixes them in the middle of the column 3. Several steel reinforcement frames and concrete are distributed on the outside of the hollow mold boxes 2.
[0024] The technical principle and beneficial effects of this utility model are as follows:
[0025] This solution uses tie rods 5 to fix the two hollow mold boxes 2 in the middle of the column 3 to support the hollow mold boxes 2, prevent the hollow mold boxes 2 from getting too close to the bottom, and prevent the hollow mold boxes 2 from floating upwards after the concrete is poured. This can position the hollow mold boxes 2 and improve the quality of construction.
[0026] The column 3 has a protrusion 4 at its center to limit the lower position of the hollow mold box 2. This prevents the hollow mold box 2 from sliding downwards on the column 3.
[0027] The hollow mold box 2 has side lugs on its side wall, and both ends of the pull rod 5 are threadedly connected to the side lugs. The side lugs facilitate fixing to the pull rod 5.
[0028] At least two columns 3 are provided between the two hollow mold boxes 2 to improve support strength and stability.
[0029] The upper and lower ends of the column 3 are respectively fixed to the steel reinforcement cage. This allows the upper and lower ends of the column 3 to be fixed when the wire mesh is tied, thus locking the position of the hollow formwork 2 on the floor slab, and making subsequent pouring more convenient.
[0030] The outer wall of the column 3 is made of non-metallic material. The hollow mold box 2 is made of stainless steel to prevent corrosion from contact with the hollow mold box 2.
[0031] The column 3 is made of precast concrete, which allows it to better integrate with the concrete floor slab to form a unified structure.
[0032] In addition, by combining two hollow mold boxes 2 together, the bottom area of a single mold box does not need to be set too large. The gap between the two hollow mold boxes 2 serves as an air vent. When pouring concrete, it is poured from both sides, and the concrete flows to the middle gap. Then the middle gap is poured to avoid hollow areas in the middle of the hollow mold box 2.
[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
