Description

Technical Field

[0001] The utility model relates to a universal mould for a composite plate without slotting. Background Art

[0002] Composite slabs are also called composite floor slabs. Composite floor slabs are assembled integral slabs made of prefabricated slabs and cast-in-place reinforced concrete layers. Composite floor slabs have good integrity, and the upper and lower surfaces of the slabs are flat, which is convenient for the decoration of the finishing layer. They are suitable for high-rise buildings and large-span buildings that require high overall rigidity.

[0003] The existing laminated plate mold structure is shown in Chinese patent CN208529362U, and the existing problems are:

[0004] 1. Traditional laminated plate molds are designed for different steel bar spacings. Laminated plates need to be produced with fixed molds. The mold design and production workload is large, the mold versatility is low, and the cost is high.

[0005] 2. Traditional composite slab molds are grooved in the side molds according to different steel bar insertion conditions. The cutting workload is large and the efficiency of mold cutting is low, which restricts the online speed of the composite slab molds. At the same time, the slots need to be processed during the subsequent production of concrete pouring to prevent leakage during vibration. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide a universal mold for composite plates without slotting. By adjusting the internal dimensions of the side molds, a set of molds can be used to produce composite plates of any size, thereby greatly improving the versatility of the mold. The elasticity of the rubber strips is used to fill the gaps around the steel bars, effectively reducing leakage of concrete during subsequent vibration.

[0007] In order to solve the above technical problems, the utility model provides a universal mold for composite plates without slotting, including a horizontally arranged long strip side mold bottom plate, a plurality of nuts welded on the upper side of the side mold bottom plate and spaced apart along its length direction, a plurality of ribs welded on the upper side of the side mold bottom plate and spaced apart along its length direction, the ribs are vertically arranged, and the normal direction of the ribs is consistent with the length direction of the side mold bottom plate, a horizontally arranged long strip steel bar bottom plate is provided on the upper side of the side mold bottom plate near one edge in the width direction, the steel bar bottom plate is provided with a rubber strip matching the upper side of the steel bar bottom plate, a top plate of the horizontally arranged long strip side mold is provided above the side mold bottom plate, and the side mold bottom plate is provided with a plurality of nuts welded on the upper side of the side mold bottom plate. The length direction of the mold top plate is consistent with the length direction of the side mold bottom plate, the two sides of the side mold top plate in the length direction are flush with the two sides of the side mold bottom plate in the length direction, and a vertical plate extending vertically downward is provided at the edge of one side of the side mold top plate close to the rubber strip in the width direction. The lower side of the vertical plate is abutted against the upper side of the rubber strip, and the upper side of the rib plate is abutted against the lower side of the side mold top plate. A through hole vertically penetrating the side mold top plate is provided at each nut on the side mold top plate, and each through hole is provided with a connecting bolt. The screwing end of each connecting bolt is located on the upper side of the side mold top plate, and the threaded end of each connecting bolt passes through the corresponding through hole from top to bottom and is screwed with the nut at the corresponding position.

[0008] For the purpose of simple explanation, the universal mold for composite plates without slotting described in the utility model is referred to as this mold for short.

[0009] The process flow of this mold:

[0010] 1. Use the laser cutting machine to cut the mold parts, complete the welding of the side mold bottom plate and the side mold top plate, and weld the ribs and nuts to the side mold bottom plate;

[0011] 2. Use glue to stick the rubber strip to the bottom plate of the side mold. After checking and confirming that the four side molds are tight and the size is correct, connect it to the mold base through a pressure rod, magnetic box or bolt to ensure that there will be no displacement or loosening during the production process;

[0012] 3. After the steel bars are tied or the steel mesh is installed, install the side formwork top plate and firmly connect it to the side formwork bottom plate through connecting bolts. The side formwork top plate presses the steel bars into the rubber strip and uses the elasticity of the rubber strip to fill the gaps around the steel bars. After the above processes are completed, check that everything is correct and then pour concrete to enter the composite slab production stage.

[0013] Advantages of this mold:

[0014] 1. The production cycle of this mold is advanced and can be synchronized with the in-depth design. It has a simple structure and is easy to install.

[0015] 2. This mold does not need to groove according to the reinforcement situation, which improves the cutting efficiency and eliminates the subsequent slot hole sealing operation, thereby improving work efficiency.

[0016] 3. Rubber strips are pasted on the bottom plate of the steel bars of this mold (different steel bar diameters correspond to rubber strips of different thicknesses), and the top plate of the side mold presses the steel bars into the rubber strips. The elasticity of the rubber strips is used to fill the gaps around the steel bars, effectively reducing the leakage of subsequent vibrating concrete and reducing the workload of cleaning the mold platform in the next process.

[0017] 4. The position of the steel bar can be adjusted arbitrarily on the rubber strip. By adjusting the internal size of the side mold, the function of producing composite panels of any size with one set of molds can be realized, which greatly improves the versatility of the mold and effectively reduces the mold cost.
