Description

Technical Field

[0001] This utility model relates to the field of precast composite slab technology, and in particular to an integrated mold for a large-span prestressed composite slab. Background Technology

[0002] Prestressed composite slabs, as a new type of building component, have been widely used in modern construction engineering. They combine the advantages of precast components and cast-in-place concrete, offering numerous benefits such as fast construction speed, good structural performance, and savings in formwork. However, demolding often requires significant external force, which can easily damage the surface of the prestressed composite slab, reducing the product's appearance quality and pass rate. It can also damage the mold, increasing maintenance and replacement costs, reducing production efficiency. Furthermore, the molds have low integration, often consisting of multiple spliced ​​parts, which can easily lead to precision errors during assembly, resulting in large dimensional deviations after mold assembly and affecting the forming quality of large-span prestressed composite slabs.

[0003] Therefore, this application provides an integrated mold for large-span prestressed composite slabs to meet the requirements. Utility Model Content

A fixing frame for fixing steel wires is provided on one side of the baffle, and a tensioning mechanism is provided on one side of the other set of side plates. The tensioning mechanism is connected to the fixing frame via steel wires. The baffle has through holes for the steel wires to pass through. A limiting groove adapted to the end of the baffle is provided on the side plate. The locking mechanism also includes a limiting buckle, and one side of the side plate is connected to the limiting buckle for limiting the baffle, facilitating mold assembly.

[0006] Preferably, the baffle further includes a positioning plate and a locking pin. The locking pin is rotatably connected to one side of the baffle via a pin shaft, and a handle is connected to the other side of the baffle via the positioning plate, making it easy to demold the mold.

[0007] Preferably, the position of the locking pin is adapted to that of the limiting buckle, and the locking pin is limited by the limiting buckle.

[0008] Preferably, the fixing frame further includes a placement plate and hooks. The placement plate is fixed to the base plate by a reinforcing member. Multiple sets of hooks are provided. The placement plate has threaded holes that are adapted to the position and size of the hooks. The hooks pass through the placement plate and are connected to nuts, so that the mold can be easily subjected to wire tensioning processing.

[0009] Preferably, the tensioning mechanism further includes a positioning component and a cylinder. The cylinder is fixed to the base plate by bolts. The cylinder has a positioning hole that matches the size of the perforation position. The cylinder is fixed to the base plate by a cylinder bracket, so that the device can limit the position of the steel wire.

[0010] Preferably, multiple sets of positioning elements and cylinders are provided, and the positions of the positioning elements and cylinders correspond to those of the cylinders.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] In this invention, the connection between the side plates, baffles, and bottom plates is tight and stable, reducing the number of splicing parts, improving the integration of the mold, reducing the time and workload of mold assembly and disassembly, improving production efficiency, meeting the needs of large-scale industrial production, ensuring product quality, and, in conjunction with the limiting buckle, locking pin, and other structures of the locking mechanism, ensuring the firmness of mold assembly while providing convenience for demolding.

[0013] In this invention, a tensioning mechanism and a fixing frame are provided. The placement plate of the fixing frame is firmly fixed to the base plate by reinforcing members. Multiple sets of hooks can be flexibly installed to facilitate the fixing of steel wires. The cylinder of the tensioning mechanism is stably installed on the base plate by bolts and cylinder brackets. The positioning member cooperates with the cylinder to make the fixing and tensioning operation of the other end of the steel wire more precise and convenient.

The cylinder 11 is fixed to the base plate 1 by bolts. The cylinder 11 has a positioning hole that matches the size of the through hole 35. The cylinder 11 is fixed to the base plate 1 by a cylinder bracket 10. There are multiple sets of positioning components 9 and cylinders 11. The positions of the positioning components 9 and cylinders 11 correspond to each other, which makes it easier to tension the prestressed steel wire in the composite plate.

[0024] As one embodiment of this invention, in order to make demolding easier and faster after the composite plate is formed, a limiting groove 21 adapted to the end of the baffle 3 is provided on the side plate 2; the locking mechanism also includes a limiting buckle 8, one side of the side plate 2 is connected to the limiting buckle 8 for limiting the baffle 3, the baffle 3 also includes a locking plate 31 and a locking pin 34, the locking pin 34 is rotatably connected to one side of the baffle 3 through a pin 33, in order to make demolding easier after the composite plate is formed, a handle 32 is connected to the other side of the baffle 3 through the locking plate 31, the baffle 3 also includes a locking plate 31 and a locking pin 34, the locking pin 34 is rotatably connected to one side of the baffle 3 through a pin 33, the other side of the baffle 3 is connected to the handle 32 through the locking plate 31, so that the baffle can be pulled out directly and easily from the top or the side, which facilitates the demolding of the composite plate.

[0025] The working principle of this practical application is as follows: When forming a prestressed composite slab, the side plate 2 is first fixed to the base plate 1 using the fastener 7. Then, the placement plate 4 in the fixing frame is fixed to the base plate 1 using the reinforcing member 6.

Then, the locking pin 34 on the baffle 3 is rotated so that the locking pin 34 is turned out from the limiting buckle 8. Then, the baffle 3 can be pulled and shaken up and down by pulling the handle 32 on the baffle 3 to separate it from the composite plate. After the baffle 3 is taken out from the limiting groove 21 of the side plate 2, the side plate 2 is no longer limited. After the side plate 2 is separated from the composite plate, the molding of the composite plate is completed.
