Description

Technical Field

[0001] This utility model relates to the field of building engineering, specifically to a casting template for the production of composite concrete slabs. Background Technology

[0002] Reinforced concrete composite slabs utilize a factory-prefabricated base slab with on-site casting of slab joints and surface layers. The prefabricated base slab requires protruding reinforcing bars at its ends. After the upper layer of concrete is poured, these bars are anchored into the subsequent layers to ensure the continuity and integrity of the slab. This construction method offers good load-bearing performance and is widely used; however, the protruding reinforcing bars at the slab ends require slotting the sides of the production mold. Because the reinforcement details of slabs vary across different projects, the slotting positions on the molds are inconsistent, resulting in poor mold versatility and increased production costs for the prefabricated base slabs.

[0003] Currently, a utility model patent with publication number CN214981842U discloses a slot-type self-locking composite slab mold, specifically relating to a slot-type self-locking composite slab mold. It includes a bottom mold and side molds. The side mold includes horizontal guards arranged parallel to each other front and rear, and side guards arranged parallel to each other longitudinally. Limiting slots are vertically provided at both ends of the horizontal guards, and limiting plugs are provided at the ends of the side guards. This utility model, by changing the structure of the slots and plugs and adopting a corrugated inner surface of the side mold, facilitates demolding while ensuring the irregular side surface of the composite slab, which is beneficial for the bonding of the composite slab with concrete pouring, reducing processes and manufacturing costs.

[0004] As can be seen from the above-disclosed technical content, as prior art, the utility model with announcement number CN214981842U changes the slot and plug structure and adopts a corrugated inner surface of the side mold. This facilitates demolding while ensuring the irregular side surface of the composite plate, which is beneficial to the bonding of the composite plate with the concrete pouring and reduces the number of processes and manufacturing costs. However, the inner corrugation of this patent is mainly used to facilitate demolding and cannot solve the problem that multiple ribs at multiple plate ends require multiple corresponding production molds, thus increasing the production cost of precast base plates. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model provides a casting template for the production of concrete composite slabs, which simplifies the reinforcement surface and eliminates the need for grooving on the sides of the mold, thereby effectively improving the versatility of the mold and reducing production costs.

[0006] To achieve the above objectives, this utility model provides a casting template for the production of composite concrete slabs, comprising a base plate, side molds, corrugated steel plates, magnetic supports, pressure rods, pressure claws, and limiting bolts. The side molds are provided on the upper surface of the base plate, and the corrugated steel plates are placed inside the side molds. The corrugations of the corrugated steel plates are equally spaced trapezoidal corrugations. At least one pressure rod spans the side molds through magnetic supports at both ends, and the pressure claws are installed on the pressure rods and fixed with limiting bolts. The upper surface of the base plate is smooth.

[0007] In addition, the casting template for producing composite concrete slabs according to the above embodiments of this utility model may also have the following additional technical features:

[0008] As a further improvement of this utility model, the corrugations of the corrugated steel plate are equally spaced rectangular corrugations.

[0009] As a further improvement of this utility model, the thickness of the corrugated steel plate is 1.2 to 3 millimeters.

[0010] As a further improvement of this utility model, the pressure rod is fixed to the side mold or the bottom plate by magnetic supports at both ends.

[0011] As a further improvement of this utility model, the end of the pressure claw is arc-shaped.

[0012] As a further improvement of this utility model, the pressure claw is fixed to the pressure rod by a collar or a clamp.

[0013] By means of the above solution, this utility model has at least the following advantages: Compared with conventional templates, by adding corrugated steel plates to the inner side of the side mold, the side mold does not need to open slots for the reinforcing bars to pass through, which simplifies the reinforcing bar surface and eliminates the need for slotting on the side of the mold, thereby improving the processing efficiency and versatility of the template. By setting pressure bars, the reinforcing bars can be prevented from floating due to vibration during the production of precast base plates, which can effectively improve the versatility of the mold and reduce production costs.

[0018] The following description, in conjunction with the accompanying drawings, describes the casting template used in the production of concrete composite slabs according to this utility model.

[0019] In Embodiment 1 of this application, as Figure 1 and Figure 2As shown, the casting template for the production of this concrete composite slab (hereinafter referred to as "the present invention") includes a base plate 1, a side mold 2, a corrugated steel plate 3, a magnetic support 4, a pressure rod 5, a pressure claw 6, and a limiting bolt 7. The side mold 2 is provided on the upper surface of the base plate 1, and the corrugated steel plate 3 is placed inside the side mold 2. The corrugations of the corrugated steel plate 3 are equally spaced trapezoidal corrugations. At least one pressure rod 5 spans the side mold 2 through the magnetic support 4 at both ends. The pressure claw 6 is installed on the pressure rod 5 and fixed with the limiting bolt 7. The upper surface of the base plate 1 is smooth.

[0020] A newborn blue light therapy eye mask (hereinafter referred to as "the patent") with utility model announcement number CN202320557500.X, by changing the slot and plug structure and adopting a corrugated inner surface of the side mold, facilitates demolding while ensuring the irregular side of the composite plate, which is beneficial to the bonding of the composite plate with the concrete pouring, and reduces the process and manufacturing cost. However, the inner corrugation of the patent is mainly used to facilitate demolding and cannot solve the problem that multiple plates with ribs at the ends require multiple corresponding production molds, thus increasing the production cost of precast base plates. The present invention, by adding a corrugated steel plate to the inner side of the side mold 2, eliminates the need to open slots for the ribs to pass through the side mold 2, improves the processing efficiency and versatility of the template, and effectively solves the problem of increased production cost of precast base plates.

[0021] This second embodiment is basically the same in structure as the first embodiment, the difference being that, as Figure 3 As shown, the corrugations of the corrugated steel plate 3 are equally spaced rectangular corrugations.

[0022] To further optimize the working efficiency of this application, the mold can be made of trapezoidal or rectangular corrugated steel plate 3 as needed, and has sufficient supporting force. The thickness of the corrugated steel plate 3 is 1.2 to 3 mm. For ease of use, the pressure rod 5 is fixed to the side mold 2 or the base plate 1 by magnetic supports 4 at both ends. To facilitate the fixing of the pressure claw 6 to the lifting ring or trestle, the end of the pressure claw 6 is arc-shaped. The pressure claw 6 is fixed to the pressure rod 5 by collars or clips, and the fixing position is determined according to the position of the lifting ring or trestle on the precast base plate.

[0023] When using it, install the casting template for producing concrete composite slabs and spray a release agent, and the template can be put into use.

[0024] When this utility model is used, its specific operation is as follows:

[0025] When in use, adjust the position of the pressure claw 6 as needed, then adjust the position of the pressure rod 5, select a trapezoidal or rectangular corrugated steel plate 3 to place in the side mold 2 and fit it against the inner side of the side mold 2, and after laying the reinforcing bars, you can start pouring concrete.

[0026] In summary, the casting template for producing concrete composite slabs according to this utility model embodiment, by adding a corrugated steel plate to the inner side of the side mold 2, eliminates the need for slots in the side mold 2 for the reinforcing bars to pass through, thus simplifying the reinforcing bar surface and eliminating the need for slotting on the side of the mold. This improves the processing efficiency and versatility of the template. By setting the pressure bar 5, it can prevent the reinforcing bars from floating up due to vibration during the production of the precast base slab, effectively improving the versatility of the template and reducing production costs.
