[0002] Prefabricated construction refers to the transfer of a large amount of on-site work from traditional construction methods to factories. It is a new type of building production method characterized by standardized design, factory production, assembly construction, integrated decoration, and information management, based on the model of prefabricated component production in factories and on-site assembly installation. The main types of prefabricated concrete components used in prefabricated buildings include: exterior wall panels, interior wall panels, composite slabs, balconies, air conditioning panels, stairs, prefabricated beams, and prefabricated columns.

[0003] Because the precast staircase components are large and heavy, the installation and dismantling process is quite troublesome. Therefore, there is an urgent need for an improved technology to solve the problems existing in the current technology. Summary of the Invention

[0004] The purpose of this invention is to provide a pulley device for the side formwork of stairs, which is proposed to solve the problem that the existing prefabricated stair components are large and heavy, making the installation and disassembly process cumbersome.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pulley device for a staircase side mold, comprising a front mold and a rear mold, wherein the front mold comprises a front mold, a first connecting frame, a first pulley connector, and a first pulley, the front mold and the first pulley connector being respectively connected to the upper and lower ends of the first connecting frame, and the first pulley being connected to the first pulley connector; the rear mold comprises a rear mold, a second connecting frame, a second pulley connector, and a second pulley, the rear mold and the second pulley connector being respectively connected to the upper and lower ends of the second connecting frame; telescopic support members are respectively provided on the first connecting frame and the second connecting frame; a staircase model cavity is formed between the front mold and the rear mold by a barrier; a plurality of teeth are provided on the inner sidewall of the front mold; a plurality of tooth grooves are provided on the inner sidewall of the rear mold; and the teeth and tooth grooves are mutually matched.

[0006] As a further description of the above technical solution:

[0007] The top of the front mold and the rear mold are provided with casting holes.

[0008] As a further description of the above technical solution:

[0009] Both sides of the front mold and the rear mold are provided with fixing plates, and the fixing plates on the front mold and the rear mold are connected by bolts.

[0010] As a further description of the above technical solution:

[0011] The first pulley and the second pulley are set perpendicularly to each other in their sliding directions.

[0012] As a further description of the above technical solution:

[0013] The first connecting frame is provided with a first limiting groove, the second connecting frame is provided with a second limiting groove, the front mold is provided with a first limiting body, and the rear mold is provided with a second limiting body. The first limiting body matches the first limiting groove, and the second limiting body matches the second limiting groove.

[0014] As a further description of the above technical solution:

[0015] The first limiting body is provided with a protrusion, and the second limiting body is provided with a groove, wherein the protrusion and the groove are matched.

[0016] As a further description of the above technical solution:

[0017] Both the first connecting frame and the second connecting frame are provided with connecting grooves, and the telescopic support is connected to the connecting grooves.

[0018] As a further description of the above technical solution:

[0019] The telescopic support includes a connecting rod, a sleeve, and an abutment body, with the connecting rod and the abutment body respectively screwed to the upper and lower ends of the sleeve.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] 1. In this invention, a first connecting frame is set at the bottom of the front mold, a first pulley connector is set at the bottom of the first connecting frame, and a first pulley is set at the bottom of the first pulley connector. A second connecting frame is set at the bottom of the rear mold, a second pulley connector is set at the bottom of the second connecting frame, and a second pulley is set at the bottom of the second pulley connector. The sliding directions of the first and second pulleys are perpendicular. When prefabricating stair components, it is only necessary to slide the first pulley and the second slide rail, and then use bolts to pass through the fixing plate to close the front and rear molds, and then pour the concrete to form a stair model. When disassembling, it is only necessary to remove the bolts, slide the first pulley and the second pulley, and take out the prefabricated stair component. This structure makes it convenient to manufacture the prefabricated stair component mold when making stairs, without the need for hoisting, and it is also easy to disassemble, which greatly improves the production efficiency of prefabricated stairs.

[0022] 2. In this invention, by setting a number of teeth on the inner wall of the front mold and a number of tooth grooves on the inner wall of the rear mold, the teeth and tooth grooves are matched, which further improves the mold closing accuracy and the quality of the prefabricated staircase.

[0023] 3. In this invention, by setting up a telescopic support, when the mold is being poured, the sleeve needs to be rotated so that the abutment body abuts against the ground, so that the mold will not shake during pouring, thereby improving the production quality of the precast stair components.
