Description

Technical Field

[0001] This utility model relates to the field of PC component technology, and in particular to a variable-pitch double-layer tooth mold. Background Technology

[0002] Precast floor slabs generally require molds during production. Existing molds are shown in the instruction manual. Figure 6 The precast floor slabs shown are constructed from overlapping angle steel, and openings need to be made in the angle steel to place reinforcing bars. However, due to the varying sizes and specifications of precast floor slabs, the existing mold can only be used to cast one type of precast floor slab. The existing molds have poor versatility, and each size of precast floor slab requires a matching mold, resulting in high mold costs. Furthermore, the existing molds are generally fixed by screws and pressure plates, making mold installation and disassembly inconvenient. Utility Model Content

[0003] The purpose of this invention is to provide a variable-spacing double-layer toothed mold. By combining a flexible lower toothed mold and a rigid upper toothed mold, reinforcing bars can be placed at any position and molds of any size can be built, thereby improving the versatility of the mold and solving the problem of poor versatility of existing molds.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A variable-spacing double-layer toothed mold includes multiple sets of toothed mold components mounted on a mold platform; one end of one toothed mold component is attached to the inner wall of another toothed mold component located adjacent to it, and the polygonal frame formed by multiple toothed mold components matches the outer contour of the precast floor slab.

[0006] The tooth mold assembly includes a flexible lower tooth mold and a rigid upper tooth mold, with the rigid upper tooth mold pressing against the flexible lower tooth mold;

[0007] The ends of the main reinforcement bars of the precast floor slab are clamped between the flexible lower tooth mold and the rigid upper tooth mold.

[0008] Precast floor slabs are mostly rectangular in shape, and their casting molds are generally composed of four sets of toothed mold components forming a rectangular frame. When assembling the mold, two adjacent flexible lower toothed molds are placed vertically first, and then the corresponding main reinforcement bars are placed on the flexible lower toothed molds. The main reinforcement bars can be placed in any position as needed. A rigid upper toothed mold is placed on each flexible lower toothed mold. The main reinforcement bars can be inserted into the flexible lower toothed mold by their own weight and the pressure of the rigid upper toothed mold, while the lower end face of the rigid upper toothed mold fits against the flexible lower toothed mold to form a seal, thus completing the mold assembly work quickly and conveniently.

[0009] The present invention is further configured such that the flexible lower tooth mold is elongated and its material is rubber.

[0010] The flexible lower tooth mold includes a rectangular base and a hollow elliptical support body disposed on the upper end of the rectangular base. The rectangular base and the hollow elliptical support body are integrally formed.

[0011] The rectangular base makes the flexible lower tooth mold more stable when placed on the mold table, while the hollow elliptical support has a certain degree of deformation capability.

[0012] This invention is further configured such that: a rectangular through hole is formed in the middle of the rectangular base, and a supporting steel plate is sleeved inside the rectangular through hole. By setting the supporting steel plate, the flexible lower tooth mold can be given a certain strength, preventing it from bending arbitrarily, and ensuring that the assembled mold has a certain degree of straightness.

[0013] The present invention is further configured such that the rigid upper tooth mold is a stainless steel square steel;

[0014] The rigid upper tooth mold has several protrusions formed on its inner and outer walls.

[0015] By setting protrusions, corresponding countersunk holes can be formed on the sides of the cast-in-place precast floor slabs, which can increase the bonding strength when connecting floor slabs later.

[0016] The present invention is further configured such that the tooth mold assembly is fastened to the mold platform by multiple magnetic seats;

[0017] The magnetic base includes a magnetic base body, and a pressure plate is fixed to the end of the magnetic base body; the pressure plate presses against the upper end of the rigid upper tooth mold, and the magnetic base body is attracted to the mold table.

[0018] The magnetic base allows for convenient and quick clamping and securing of the tooth mold assembly, and also facilitates the assembly and disassembly of the mold.

[0019] The present invention is further configured such that: the pressure plate includes an integrally formed connecting part and a snap-fit ​​part, the connecting part is fixedly connected to the magnetic base body, the snap-fit ​​part is in the shape of an inverted "L"; and the end of the snap-fit ​​part is formed with a downwardly protruding limiting part.

[0020] The combination of the clamping part and the limiting part can limit the rigid upper toothed mold while pressing it, preventing it from slipping and changing the overall structure of the mold.

[0021] The outstanding effect of this utility model is:

[0022] Compared with existing technologies, the combination of flexible lower tooth mold and rigid upper tooth mold allows for the placement of reinforcing bars at any position and the construction of molds of any size, improving the versatility of molds and solving the problem of poor versatility of existing molds;

[0023] The tooth mold assembly is secured with a magnetic base, which facilitates the installation and disassembly of the mold. Attached Figure Description
