Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated building construction, in particular to a prefabricated building assembly construction platform. Background Art

[0002] Prefabricated buildings refer to structural buildings that are prefabricated in factories as the main components and are quickly assembled and anchored on site. The advantages of this type of building are fast construction speed, less restrictions on climatic conditions, labor saving, and improved building quality. In the operation of prefabricated building construction, it is often necessary to build a construction platform to facilitate construction workers.

[0003] There are two main types of existing construction platforms. One is to place traction equipment on the top floor of the building and then hoist it to the construction area through steel cables; the other is to build scaffolding from the ground to the construction location. The area of ​​these two types of construction platforms is fixed. When the horizontal length of the construction area is larger than the construction platform, the platform area cannot be adjusted and needs to be readjusted, which affects the work efficiency of the construction workers. Utility Model Content

[0004] The utility model aims to solve the problem that the platform area of ​​the above-mentioned construction platform cannot be adjusted, thereby providing a prefabricated building assembly construction platform.

[0005] The utility model solves the above problems and adopts the following technical solutions:

[0006] An assembled construction platform for a prefabricated building includes a load-bearing bottom plate and protective side plates arranged around the load-bearing bottom plate. Construction workers stand on the load-bearing bottom plate to carry out construction.

[0007] The protective side plate includes three side fixing plates and one side extension plate, the three side fixing plates are respectively vertically fixed to the three side edges of the bearing bottom plate, and the side extension plate is arranged on the remaining side of the bearing bottom plate;

[0008] A fixedly installed electric push rod and a slidably installed built-in pedal are arranged inside the bearing base plate. The telescopic end of the electric push rod and the outer end of the built-in pedal are fixedly connected to the lower side of the side extension plate. The two ends of the side extension plate are connected to the adjacent side fixed plate through a side chain net. The side chain net can be tensioned and stretched when the side extension plate is away from the side fixed plate.

[0009] Compared with the prior art, the utility model adopting the above technical solution has the following beneficial effects:

[0010] 1. By starting the electric push rod to push the side extension plate out of the bearing bottom plate, the built-in pedal is extended to the outside of the bearing bottom plate under the drive of the side extension plate, and the bearing area of ​​the bearing bottom plate is expanded to adapt to the operation requirements of different positions, so as to solve the problem that the bearing area of ​​the existing prefabricated building assembly platform used in construction cannot be changed after the platform is built, resulting in poor applicability of the platform device;

[0011] 2. As the built-in pedal extends outward, the side chain net also unfolds, serving as protection for the sides of the construction platform after the area is expanded, thereby increasing the practicality and safety of the construction platform.

[0012] As a preferred embodiment, a further technical solution of the utility model is:

[0013] At least two parallel semicircular sleeves are arranged inside the bearing bottom plate, and a built-in rod is arranged in the semicircular sleeve, one end of the built-in rod is vertically fixed to the side extension plate, and the side wall of the built-in rod is in contact with the bottom surface of the built-in pedal. Through the above structure, the built-in rod provides horizontal support force for the built-in pedal, thereby increasing the stability of the built-in pedal.

[0014] The bearing bottom plate is also provided with a plurality of ball grooves, in which auxiliary balls are rolled, and the rolling surfaces of the auxiliary balls are in contact with the bottom surface of the built-in pedal. During the movement of the built-in pedal, its bottom surface is not in contact with the bottom surface of the inner wall of the bearing bottom plate under the support of the auxiliary balls, and the auxiliary balls roll on the inner wall of the ball grooves to reduce the friction resistance of the built-in pedal, so that the deployment of the built-in pedal is more labor-saving and fast.

[0015] A reinforcing rod sleeve is fixed on the side fixing plate adjacent to the side extension plate, the reinforcing rod sleeve is arranged parallel to the built-in rod, a telescopic rod is slidably arranged in the reinforcing rod sleeve, and the end of the telescopic rod extending out of the reinforcing rod sleeve is fixed to the inner wall of the side extension plate. The telescopic rod is extended and retracted in the reinforcing rod sleeve under the drive of the side extension plate, so that the upper end of the side extension plate also has a support structure, further improving the stability of the movement of the side extension plate.

[0016] A counterweight box is fixed on the outer wall of the side fixed plate opposite to the side extension plate, and several counterweight blocks are placed in the counterweight box. When the built-in pedal is in the extended state, the construction workers are working on the built-in pedal. The weight on both sides of the construction platform is different, which causes the center of gravity of the construction platform to shift. The counterweight box is set to balance the weight on both sides of the construction platform to further ensure the stability of the construction platform structure.

The telescopic end of the electric push rod and the outer end of the built-in pedal 11 are fixedly connected to the lower side of the side extension plate 4. The two ends of the side extension plate 4 are connected to the adjacent side fixed plate 3 through a side chain net 12. The side chain net 12 can be tensioned and stretched when the side extension plate 4 is away from the side fixed plate 3.

[0026] Preferably, two push rod grooves are provided in the supporting base plate 2, in which the first electric push rod 6 and the second electric push rod 7 are respectively fixed, and the output ends of the first electric push rod 6 and the second electric push rod 7 are vertically fixed to the inner wall of the side extension plate 4, and an electric wire passage is opened on the supporting base plate 2 at the lower end of the first electric push rod 6 and the second electric push rod 7, which is used to lead out the wires of the first electric push rod 6 and the second electric push rod 7, so as to facilitate the construction personnel to control the first electric push rod 6 and the second electric push rod 7.

[0027] In this embodiment, the electric push rod is started to push the side extension plate 4 out of the bearing base plate 2. At this time, the built-in pedal 11 is extended to the outside of the bearing base plate 2 under the drive of the side extension plate, and the bearing area of ​​the bearing base plate 2 is expanded to adapt to the operation requirements at different positions. This solves the problem that the bearing area of ​​the existing prefabricated building assembly platform used for construction cannot be changed after it is built, resulting in poor applicability of the platform device. In the process of the built-in pedal 11 extending outward, the side chain net 12 is also unfolded as a protection for the side of the construction platform after the area is expanded, thereby increasing the practicability and safety of the construction platform.

[0028] In this embodiment, at least two parallel semicircular sleeves are arranged inside the bearing base plate 2. Preferably, a horizontal groove for setting the built-in pedal 11 is opened inside the bearing base plate 2. The horizontal groove extends horizontally from the leftmost side of the bearing base plate 2 to the right, but does not penetrate the bearing base plate 2.
