Description

Technical Field

[0001] This utility model relates to the field of composite plate mold technology, specifically to a detachable composite plate mold sealing tooling. Background Technology

[0002] Composite slab components are widely used in prefabricated buildings. A composite 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 slab base slabs generally involves assembling a steel base mold and side molds fixed to the base mold, followed by pouring concrete.

[0003] Currently, precast reinforced concrete truss composite slabs, as the most basic horizontal component in the field of prefabricated buildings, are characterized by simple structure, wide application, and large production volume. However, traditional composite slab molds suffer from poor versatility; the ribs are positioned in slots pre-reserved in the angle steel, making it difficult to achieve mold universality for components of different sizes. Furthermore, the large number of slots leads to significant grout leakage during concrete vibration, increasing the workload of mold cleaning and formwork maintenance, increasing the labor intensity of production operations, and reducing component production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings and provide a detachable composite plate mold sealing fixture.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A detachable composite plate mold sealing fixture includes a bottom mold, on which a rubber pad is provided, and a square tube is snapped onto the rubber pad. A segmented panel is provided on one side of the square tube. The fixture also includes:

[0007] The lifting assembly, located on one side of the rubber pad, is used to lift the square tube.

[0008] Multiple bosses are provided on the side wall of the segmented panel and are integrally formed with the segmented panel;

[0009] The locking assembly includes a mounting plate fixed to the lifting assembly, and a locking bolt is provided on the mounting plate. The locking bolt passes through the square tube and is connected to the segmented panel.

[0010] Furthermore, the lifting assembly includes a fixed base plate fixed to the bottom mold, a lifting platform slidably disposed on the fixed base plate, a limiting part connected to the fixed base plate at the bottom of the lifting platform, a square tube fixed on the lifting platform, and a mounting plate fixed on the lifting platform.

[0011] Furthermore, vertical grooves are provided on both sides of the fixed base plate, the limiting part includes a slide rod located in the vertical groove, a lifting slider sleeved on the slide rod is provided on the lifting platform, and a positioning part is also provided on the lifting slider.

[0012] Furthermore, a return spring is provided at the bottom of the lifting slider, and the return spring is sleeved on the slide rod.

[0013] Furthermore, the positioning part includes a fixing block fixed to the lifting slider, and a positioning bolt is threaded onto the fixing block, the positioning bolt abutting against the fixing base plate.

[0014] Furthermore, a hanging groove is provided on the side of the square tube near the segment panel, and a hanging plate for inserting into the hanging groove is provided on the segment panel.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model enhances the versatility of the mold by connecting the tooling to the bottom mold of the composite slab. Different specifications of component sizes and reinforcement arrangement do not affect the use of the mold. After the reinforcement is inserted into the mold, it can be tightly sealed with the rubber, reducing the gaps at the reinforcement outlet of the mold and alleviating the problem of grout leakage during concrete vibration.

[0025] Reference Figures 1-4 As shown, a detachable composite slab mold sealing fixture includes a bottom mold 1, on which a rubber pad 2 is provided. Reinforcing bars extend from the rubber pad 2. The rubber pad 2 is divided into an upper rubber layer and a lower rubber layer. A cavity is pre-reserved inside the upper rubber layer and filled with EPDM foamed square strips to tightly seal it against the lower rubber layer. A square tube 4 is snapped onto the upper rubber layer, and a locking block is provided on the upper rubber layer. A square tube slot is opened at the bottom of the square tube 4, and the upper rubber layer is fixed by inserting the locking block into the slot. A segmented panel 5 is provided on one side of the square tube 4. The segmented panel 5 is at least 8mm thick and has pre-reserved bolt connection holes on its surface. The fixture is detachable and reusable by connecting it to the bottom mold 1. The height of the square tube 4 is the same as the height of the segmented panel 5, and its height must not exceed 30mm, thereby achieving tight sealing during the vibration and pouring process of the composite slab. It also includes:

[0026] The lifting component 3 is located on one side of the rubber pad 2 and is used to lift the square tube 4.
