Description

Technical Field

[0001] This utility model relates to the field of prefabricated buildings, and in particular to a double-layer universal prefabricated composite base plate mold. Background Technology

[0002] Composite floor slabs are widely used in prefabricated buildings. A composite floor slab is an integral floor slab formed by stacking a precast base slab and a cast-in-place concrete layer connected by truss reinforcement. The production of precast composite base slabs generally uses a steel base mold and side molds fixed on the base mold. After the mold is assembled, steel bars are placed in the mold, and then concrete is poured.

[0003] The prior art patent with application number CN202410805441.2 discloses a cavity-type double-layer precast composite floor slab mold. In use, the reinforcing bars extend through the middle of the grout-sealing strip, and the spacing between the reinforcing bars is not affected by the mold. Therefore, this mold is suitable for floor slab components with different reinforcing bar spacings. In use, for composite base slabs of different lengths and widths, the length of the side molds can be adjusted by lengthening or splicing. However, for the production of composite base slabs of different thicknesses, only the entire side mold can be replaced. Utility Model Content

[0004] Based on the above problems, the purpose of this utility model is to provide a double-layer universal prefabricated composite base plate mold. The technical solution adopted by this utility model is as follows:

The bottom surface of the upper side mold baffle and the top surface of the lower side mold baffle are each provided with a detachable thickness module. Each thickness module includes a strip-shaped block. An elastic grout-blocking strip is provided along the length of the sealing mating surface of the strip-shaped block. The inner side of the strip-shaped block is engaged with the upper or lower side mold baffle via a snap-fit ​​structure. The outer side of the strip-shaped block has an extension edge with mounting holes. Mounting bolts are installed in the mounting holes and are threadedly connected to the upper or lower side mold baffle.

[0006] Preferably, the snap-fit ​​structure includes an embedded hook and a hook groove, the hook being disposed on the upper baffle or lower baffle of the side mold, and the hook groove being disposed on the inner side surface of the strip-shaped block.

A spacer sleeve is fitted on the stud, and the end of the spacer sleeve abuts against the upper baffle or the lower baffle of the side mold. A fastening nut is threaded onto the stud, and the fastening nut abuts against the upper baffle of the side mold.

[0008] Preferably, a lifting ring is provided on the upper baffle of the side mold.

[0009] Preferably, a groove is provided on the sealing mating surface of the strip-shaped block, and the elastic grout-blocking strip is engaged in the groove.

[0021] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 As shown, this embodiment discloses a double-layer universal prefabricated composite base plate mold, including an upper side mold baffle 1 and a lower side mold baffle 2. The bottom surface of the upper side mold baffle 1 and the top surface of the lower side mold baffle 2 are both provided with detachable thickness modules 3.

[0023] The thickness module 3 includes a strip-shaped block 301. An elastic grout-blocking strip 302 is provided along the length of the sealing mating surface of the strip-shaped block 301. The inner side of the strip-shaped block 301 is limited and fitted with the upper baffle 1 or the lower baffle 2 of the side mold via a snap-fit ​​structure 303. The outer side of the strip-shaped block 301 is provided with an extension edge 304, on which mounting holes 305 are provided. Mounting bolts 306 are installed in the mounting holes 305 and are threadedly connected to the upper baffle 1 or the lower baffle 2 of the side mold. For the production of composite base plates of different thicknesses, only the thickness module 3 needs to be replaced.

[0024] like Figure 2 As shown, the snap-fit ​​structure 303 includes a snap hook 303-1 and a hook groove 303-2 that are embedded and fitted. The snap hook 303-1 is provided on the upper baffle 1 or the lower baffle 2 of the side mold, and the hook groove 303-2 is provided on the inner side of the strip block 301.

[0025] In this embodiment, a groove 301-1 is provided on the sealing mating surface of the strip-shaped block 301, and the elastic grout-blocking strip 302 is engaged in the groove 301-1. The groove 301-1 can be a T-shaped groove. The elastic grout-blocking strip 302 can be a hollow rubber strip.

[0026] In this embodiment, the upper baffle 1 of the side mold is mainly composed of a horizontal part and an inclined part disposed inside the horizontal part; while the lower baffle 2 of the side mold is mainly composed of a horizontal part.

[0027] In this embodiment, a stud 4 is fixed on the lower baffle 2 of the side mold, and the upper baffle 1 of the side mold is provided with an insertion hole 5 that mates with the stud 4. The diameter of the insertion hole 5 is larger than the diameter of the stud 4. A spacer sleeve 6 is fitted on the stud 4, and the end of the spacer sleeve 6 abuts against the upper baffle 1 or the lower baffle 2 of the side mold. A fastening nut 7 is threaded onto the stud 4, and the fastening nut 7 abuts against the upper baffle 1 of the side mold. The spacer sleeve 6 mainly supports the outer side of the upper baffle 1 and the lower baffle 2 of the side mold, improving overall stability. Figure 3As shown, the upper baffle 1 and lower baffle 2 of the side formwork are assembled according to the dimensions of the floor slab. The reinforcing bar 13 is positioned between the upper and lower elastic grout-blocking strips 302. Tightening the fastening nut 7 moves the upper baffle 1 downwards, causing the two elastic grout-blocking strips 302 to clamp the reinforcing bar 13 in the middle, preventing grout leakage. At this time, the end of the spacer sleeve 6 rests against the upper baffle 1 and lower baffle 2 of the side formwork. It should be noted that when the thickness module 3 is replaced, the spacer sleeve 6 also needs to be replaced to ensure that tightening the fastening nut 7 allows the two elastic grout-blocking strips 302 to clamp the reinforcing bar 13 in the middle. The height of the spacer sleeve 6 is slightly larger than the overall size of the two strip-shaped blocks 301 plus the diameter of the reinforcing bar.

[0028] In this embodiment, a lifting ring 8 is provided on the upper baffle 1 of the side mold, which facilitates the handling of the upper baffle 1 of the side mold.

[0029] For overlapping base plates of different lengths and widths, the length of the side molds is adjusted by splicing them together. For example... Figure 4 As shown, both the upper baffle 1 and the lower baffle 2 of the side mold are provided with spaced-apart pin holes 9 at their ends, and the pin holes 9 are engaged with pins 10. Vertically arranged connecting plates 11 are fixed to the ends of both the upper baffle 1 and the lower baffle 2 of the side mold, and the connecting plates 11 are provided with connecting holes 12. When two upper baffles 1 of the side mold are joined together, or two lower baffles 2 of the side mold are joined together, the pins 10 are first inserted into the pin holes 9, and then the two connecting plates 11 are fixed together using bolt assemblies.

[0030] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
