As shown in fig. 1 to 3, in a preferred embodiment of the present invention, a combined reusable laminated plate mold is provided, and its main components include a bottom mold 3, a plurality of mold segments and a sealing strip 6.

As shown in fig. 2, each mold assembly section includes a first strip-shaped side mold 1, a second strip-shaped side mold 2, and a magnetic attraction device. The second side forms 2 are assembled on the first side forms 1 to form the die section main body, and the second side forms 2 are arranged above the first side forms 1 in a superposed mode and are detachably connected and fixed through the connecting component. But first side forms 1 and second side forms 2 when the equipment, the demand sets up one between the two and seals in order to avoid appearing leaking the thick liquid phenomenon when concreting. In the present embodiment, the side surfaces of each side of the first side form 1 and the second side form 2 are spliced relatively close to each other, and the sealing between the first side form 1 and the second side form 2 can be realized by embedding a sealing strip 6 between the two opposite splicing surfaces. Because first side forms 1 and second side forms 2 are connected fixedly from top to bottom through coupling assembling itself, consequently only need in advance during the installation to imbed between first side forms 1 and the second side forms 2 sealing strip 6, then fasten through coupling assembling, can make sealing strip 6 compressed tightly between first side forms 1 and second side forms 2.

In the mold combination section, the specific materials and forms of the first side mold 1 and the second side mold 2 can be adjusted according to actual needs. In this embodiment, the first side form 1 may be a channel steel, and the second side form 2 may be an angle steel. In order to ensure the strength of the angle steel, spaced stiffening ribs 202 can be arranged on the angle steel. The channel steel and the angle steel in the die combined section can be assembled in a back-to-back mode, namely, the waist plane of the channel steel is spliced with one side face of the angle steel oppositely. And in order to guarantee that the detachable installation between them can be realized, can set up first bolt hole 101 on the waist plane of channel-section steel, also set up second bolt hole 201 on a side of angle steel, first bolt hole 101 and second bolt hole 201 can just be link up, and coupling assembling can be connected channel-section steel and angle steel through just right first bolt hole 101 and second bolt hole 201 from this.

In addition, the concrete form of the connecting component in the die assembly section can be adjusted according to the actual condition, and the threaded connecting component, the buckle type connecting component and the like can be realized. In the present embodiment, as shown in fig. 4, the connection assembly includes a square-headed screw 4 and a claw nut 5. The assembly mode is as shown in fig. 1, wherein the square head end of the square head screw rod 4 is arranged in the groove cavity of the channel steel, the screw rod end sequentially passes through the first bolt hole 101 and the second bolt hole 201, and the screw rod end is screwed and fixed on the inner side surface of the angle steel by the claw nut 5. Therefore, the distance between the first side form 1 and the second side form 2 can be controlled and adjusted by screwing the claw nut 5. In order to avoid the looseness of the square-head screw rod 4, the square-head size of the square-head screw rod 4 is preferably controlled to be slightly smaller than the inner width of the channel steel.

Additionally, the utility model discloses in, the mould segmental combination has the multistage, and each section mould segmental combination all regards as a modularization to assemble the subassembly. The mold assembly section is fixed on the bottom mold 3 through the magnetic attraction device, so that the magnetic attraction device needs to be fixed on the mold section main body, and the fixing point of the magnetic attraction device can be located on the first side mold 1 or the second side mold 2 in principle, so that limitation to the fixing point can be avoided. However, in view of the convenience of installation, the magnetic attraction means is preferably installed on the first sideform 1 located below. In order to facilitate the installation of the magnetic attraction device, in this embodiment, flange plates may be provided at the ends of the legs of the channel steel as the first side forms 1. When the mold combination section is fixed on the bottom mold 3, the flange plate is flatly attached to the surface of the bottom mold 3, and the magnetic attraction device can adopt a magnetic box 7 provided with a powerful magnet. As shown in fig. 1, the magnetic box 7 is mounted on the flange plate for magnetically fixing the mold assembly section on the bottom mold 3, and the flange plate is pressed on the bottom mold 3 to further improve the sealing property between the mold assembly section and the bottom mold 3, thereby preventing slurry leakage.

In addition, in order to cooperate with the magnetic attraction device, the bottom mold 3 needs to be made of ferromagnetic material, and a steel platform with a flat surface can be generally used. When in actual use, the moulds which are suitable for the specifications of laminated plates with any sizes can be spliced by adopting different numbers of mould combination sections according to the required sizes. Specifically, as shown in fig. 3, the multi-section mold combination sections can be continuously spliced on the bottom mold 3 in a surrounding manner to form a laminated slab pouring cavity. And each section of the mold assembly section is fixed on the bottom mold 3 through the magnetic attraction device. Moreover, because the sealing performance of each section of the mold combination section is maintained by the sealing strip 6, the sealing strip 6 can be as close as possible to the inner side of the first side form 1 and the second side form 2 facing the pouring cavity of the composite slab, and the first side form 1, the sealing strip 6 and the second side form 2 integrally form a sealing surface for preventing the concrete 802 from overflowing. However, since the built-in reinforcing bars 801 are required in the laminated slab, and the ends of the reinforcing bars 801 extend out of the side surfaces of the laminated slab, if all the sealing strips 6 around the pouring cavity of the laminated slab are regarded as forming a sealing system, a plurality of mounting holes for inserting the built-in reinforcing bars 801 in the laminated slab need to be formed in the sealing system. All positions of the whole laminated slab pouring cavity except the top and the mounting holes on the periphery are kept sealed. As shown in fig. 1, before concrete 802 is poured, steel bars 801 embedded in a laminated slab need to be bound in a laminated slab pouring cavity according to a required modulus, the end part of the sealing strip 6, which needs to be adjusted in a corresponding position, extends out, and a mounting hole for penetrating the steel bars 801 embedded in the laminated slab is formed in the position by using two sections of the sealing strips 6.

In addition, since the reinforcing bars 801 built in the laminated slab need to pass through the installation holes, the height of the first sideform 1 is preferably set to be the same as the height of the reinforcing bar protection layer of the laminated slab to be cast. For example, according to the specification requirement, the floor slab reinforcement protection layer is not less than 20mm, and if the floor slab reinforcement protection layer is set to 20mm, the height of the first side form 1 may also be set to 20 mm.

As a further preferred mode, the first bolt hole 101 and the second bolt hole 201 in the channel steel and the angle steel may be both provided as elongated holes, and the length direction of the elongated holes is along the length direction of the mold assembly. Therefore, a certain avoidance space can be reserved for mounting the built-in steel bar 801 of the laminated slab, and the square-head screw 4 and the steel bar 801 are prevented from interfering in position.

As a further preferable mode, a double-sided tape may be further provided on a contact surface of the sealing tape 6 and the second side form 2, so that the sealing tape 6 is bonded to the second side form 2 to prevent the sealing tape from falling off. The sealing strip 6 is generally in a pressing state with the first side form 1 under the action of gravity and pressure, so that a double-sided adhesive tape does not need to be arranged between the sealing strip and the first side form.

As a further preferred mode, a scale can be engraved on the first side form 1 so as to accurately adjust the assembly position of each component according to the scale reading.

In addition, the size of the first side form 1 and the second side form 2 can be adjusted according to actual needs, and for convenience of application in different scenes, the length of each single section is preferably 1 meter. Correspondingly, the sealing strips 6 are made of rubber foaming materials, the sections of the sealing strips are 20mm multiplied by 10mm, and the length of each sealing strip is 1 meter.

In addition, when concrete pouring is performed, a release agent may be coated on the surfaces of the bottom mold 3, the first and

second side molds

1 and 2, and the weather strip 6 in advance to facilitate the release.

In addition, the first side die 1 and the second side die 2 can be made of steel, aluminum or PVC, and the strength requirement can be met without limitation.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
