Description

Technical Field

[0001] This utility model relates to the field of stairwell construction, and in particular to a construction platform for stairwells. Background Technology

[0002] When building a house, multi-story buildings need to be equipped with stairs. After the stairs are installed, if construction is required in the stairwell, scaffolding must be erected using steel pipes or non-standard materials as a construction platform.

[0003] However, scaffolding needs to be erected on stairs, and the scaffolding is prone to collapse during construction, resulting in poor work safety. In addition, the scaffolding is large and heavy, and each floor needs to be repeatedly erected, which is difficult to operate and affects construction efficiency. The scaffolding erection materials are also very expensive, and the construction process of scaffolding in stairwells is complicated, time-consuming, wasteful of materials, and has poor safety guarantee. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing technologies, such as the difficulty in ensuring the safety of scaffolding erection in stairwells and the low construction efficiency of stairwells, and to provide a construction platform for stairwells.

[0005] This utility model provides a construction platform for stairwells, including...

[0006] A support plate having a first retaining part and a second retaining part, the first retaining part and the second retaining part being located at both ends of the support plate, the first retaining part being used to abut against the staircase and the second retaining part being used to abut against the floor beam;

[0007] The support frame has its bottom end abutting against the staircase and its top end connected to the support plate.

[0008] This utility model discloses a construction platform for stairwells. A first clamping part and a second clamping part are respectively provided at both ends of the supporting plate. The first clamping part is clamped onto the floor beam, and the second clamping part is clamped onto the staircase, ensuring good support for the supporting plate and preventing positional displacement during construction. The bottom end of the support frame abuts against the staircase, and the top end connects to the supporting plate, providing excellent support for the supporting plate, improving its load-bearing capacity, and further ensuring the safety of construction workers. When using the platform, workers can perform construction work in the stairwell by stepping on the supporting plate.

[0009] Preferably, the support frame includes a vertical brace, a first diagonal brace, and a second diagonal brace. The bottom of the vertical brace abuts against the staircase, and the top is connected to the support plate. One end of the first diagonal brace is connected to the vertical brace, and the other end is connected to the support plate. One end of the second diagonal brace is connected to the vertical brace, and the other end is connected to the support plate. The first diagonal brace and the second diagonal brace are located on both sides of the vertical brace.

[0010] The vertical and horizontal braces are connected to form a triangular support, which reduces the area occupied by the bottom of the support frame and makes it more suitable for installation on stairs. The bottom of the vertical brace abuts against the stairs, providing good support for the support plate. Since the stairs are uneven, the triangular support facilitates the installation and fixing of the support frame, thereby improving construction efficiency.

[0011] Preferably, the vertical support includes a first horizontal bar and two parallel vertical bars. The top end of the vertical bars is connected to the support plate, and the bottom end abuts against the stairs. The two ends of the first horizontal bar are respectively connected to the vertical bars.

[0012] The support plate is supported by two vertical bars, making it more stable; the two vertical bars are connected by a first horizontal bar, thus ensuring the structural strength of the vertical support.

[0013] Preferably, the first diagonal brace includes a second horizontal bar and two parallel first diagonal bars, one end of the first diagonal bar is connected to the support plate and the other end is connected to the vertical bar, and the two ends of the second horizontal bar are respectively connected to the first diagonal bars; the second diagonal brace includes a third horizontal bar and two parallel second diagonal bars, one end of the second diagonal bar is connected to the support plate and the other end is connected to the vertical bar, and the two ends of the third horizontal bar are respectively connected to the second diagonal bars.

[0014] The first diagonal brace is composed of two first diagonal rods, which are connected and reinforced by a second crossbar; the second diagonal brace is composed of two second diagonal rods, which are connected and reinforced by a third crossbar; thus ensuring that the supporting plate is more stable.

[0015] Preferably, the first diagonal brace is detachably connected to the vertical brace, the second diagonal brace is detachably connected to the vertical brace, and the first diagonal brace, the second diagonal brace, and the vertical brace are detachably connected to the supporting plate.

[0016] It facilitates the installation of the support frame on the support plate. When moving the construction platform, the platform can be disassembled into multiple parts for transport, reducing the difficulty of transportation and making the support frame more convenient and faster to move, thereby improving construction efficiency.

[0017] Preferably, the supporting plate is a rectangular plate, comprising a first plate, a second plate, and a third plate. The first plate and the third plate are located on opposite sides of the second plate. The first plate and the second plate are slidably connected, and the third plate is slidably connected to the second plate. The first diagonal brace is slidably connected to the first plate, and the second diagonal brace is slidably connected to the second plate. The vertical brace is connected to the second plate. The second plate is provided with a first limiting member and a second limiting member, wherein the first limiting member can limit the first plate, and the second limiting member can limit the second plate.

[0018] The length of the support plate can be adjusted by the relative sliding between the first plate and the second plate, and between the third plate and the second plate. The limiting action of the first and second limiting members allows the support plate to adapt to different stairwell constructions. The first diagonal brace supports the first plate, and the second diagonal brace supports the third plate, providing good support for the support plate and ensuring the safety of construction workers.

[0019] Preferably, the supporting plate includes a steel mesh structure and a frame structure, the steel mesh structure is laid on the frame structure, and the support frame is connected to the frame structure.

[0020] While ensuring the structural strength of the support plate, the weight of the support plate is reduced, making it easier to transport and install.

[0021] Preferably, the supporting plate is provided with a guardrail, and the bottom end of the guardrail is detachably connected to the supporting plate.

[0022] The guardrail is installed on the side of the support plate to prevent workers from falling; in some embodiments, guardrails are installed on both sides of the support plate; the guardrails are detachably connected to the support plate for easy handling.

[0023] Preferably, the top of the support plate is provided with a lifting lug.

[0024] By connecting the lifting equipment to the lifting lugs, the support plate can be lifted more easily, facilitating its installation and disassembly.

[0025] Preferably, the bottom of the support frame is provided with an anti-slip component, which abuts against the staircase.

[0026] Anti-slip components prevent the support frame from slipping, making it more securely fixed on the stairs and further ensuring the safety of workers.
