Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a support platform for elevator shaft protection and construction. Background Technology

[0002] With the rapid development of my country's construction industry, safety requirements during construction are becoming increasingly stringent, especially with the proliferation of elevator shafts in high-rise buildings. These shafts vary in size and specifications, posing significant construction safety risks. Preventing falls from heights has become a key focus of safety management within the industry. The conventional method for elevator shaft construction involves erecting a scaffold for protection and support at the base. This method is time-consuming, labor-intensive, and costly. Therefore, selecting a protective support method suitable for different elevator shaft specifications is crucial for ensuring safety and facilitating the construction of secondary structural walls within the elevator shaft.

[0003] CN219491762U discloses a foldable and reusable shaft unloading platform device, including a base frame, a base plate, and a surrounding panel assembly. The base frame has lifting parts on both sides. The base plate is fixed to the base frame. The surrounding panel assembly includes a first side plate, a second side plate, and a rear plate, which are respectively connected to the top edge of the base plate via hinges. The first side plate, the second side plate, and the rear plate are folded onto the surface of the base plate, and the top edges of the first side plate and the second side plate have mating insertion parts, which confine the rear plate below the first side plate and the second side plate and above the base plate. The first side plate, the second side plate, and the rear plate can be unfolded and are perpendicular to the base plate, forming a enclosure structure with an opening on one side. The mating edges of the first side plate, the second side plate, and the rear plate after unfolding have locking parts. This prior art proposes to connect the surrounding panel assembly to the top edge of the base plate via hinges, and the surrounding panel assembly can be folded onto the surface of the base plate. However, the base plate size is fixed, making it difficult to match different shaft specifications.

[0004] CN205935610U discloses an elevator shaft operating platform, including an operating platform frame, which is supported in the elevator shaft by a support member; the support member is detachably fixed to the wall in the elevator shaft; and a base plate is laid on the top surface of the operating platform frame. This prior art proposes a reusable solution for the detachable support member and steel structure frame, which reduces material waste, but the fixed dimensions of the platform frame are difficult to meet the diverse needs of different elevator shafts.

[0005] In summary, existing technologies still have the problem of fixed-size platforms being unable to flexibly match different wellbore specifications. Utility Model Content

[0006] To address the shortcomings of existing technologies, the technical problem solved by this utility model is to provide a support platform for elevator shaft protection and construction, thereby solving the problem that existing fixed-size platforms are difficult to flexibly match different shaft specifications.

[0007] To solve the above problems, the technical solution adopted by this utility model is: a support platform for elevator shaft protection and construction, including a platform plate and a flap plate; The platform board is composed of multiple standard boards, which are hinged to each other by at least three fixed hinges fixed to the longitudinal edges of the standard boards. The fixed hinges are spaced apart on the top and bottom surfaces of the standard boards, allowing the standard boards to be folded together. The flip board includes two longitudinal boards and multiple transverse boards. The longitudinal boards are hinged to the longitudinal edges of the standard boards by at least three detachable hinges. The transverse boards are hinged to the transverse edges of the standard boards by at least two detachable hinges.

[0008] Compared with existing technologies, the beneficial effects of this solution are: the platform plate can be folded and unfolded through the fixed hinge connection between the standard plates, and the length of the platform plate can be flexibly adjusted to adapt to the width of different shafts. At the same time, the foldable design of the platform plate also facilitates transportation and storage, and reduces space occupation.

[0009] Furthermore, the detachable hinge includes a first page and a second page. The first page is fixedly mounted on a standard plate, and the second page is fixedly mounted on a flip plate. A hinge shaft hole is fixed to the side of the first page, and a hinge shaft is fixed to the side of the second page. The hinge shaft can be inserted into and rotate within the hinge shaft hole. This rotation within the hinge shaft hole allows the flip plate to adjust its tilt angle according to different structures of the elevator shaft wall, enhancing the fit between the support platform and the wall.

[0010] Furthermore, the platform plate and the flap are made of 3mm thick patterned steel plate, and the shortest distance from the edge of the platform plate to the surface of the shaft structure is not less than 300mm. The textured surface of the patterned steel plate increases friction and effectively prevents workers or tools from slipping; the flap can serve as a temporary guardrail or extend the working surface, and the 300mm distance is sufficient for most shafts.

[0011] Furthermore, the platform plate is composed of an even number of standard plates, and lifting rings are also provided on the standard plates on both sides of the platform plate.

[0012] Furthermore, the standard plate has two lifting rings, which are fixed to the standard plate symmetrically about the horizontal axis of the standard plate.

[0013] Furthermore, the lifting ring is made of HPB300 steel bar with a diameter of 16mm, bent into a U-shape or circle, and welded and fixed to a standard plate. The lifting ring is a fixing tool used for lifting, reducing the hassle of binding ropes.

[0014] Furthermore, a channel steel is fixed to the bottom of the standard plate, and the channel steel is welded and fixed to the bottom of the standard plate at the waist height position, and a rubber layer is bonded and fixed to the inner surface of the channel steel.

[0015] Furthermore, the width of the channel steel leg is the same as the thickness of the fixed hinge. This design allows the standard panels to be folded and fitted together without being affected by the protruding width of the channel steel leg.

[0016] Furthermore, the channel steel includes edge channel steel and intermediate channel steel. The centerline of the edge channel steel is no more than 200mm from the surface of the elevator shaft, and the centerline spacing of the intermediate channel steel is no more than 900mm and they are evenly distributed along the elevator shaft. The position design of the edge channel steel controls the cantilever length of the standard plate, reducing the risk of the standard plate tipping over; the design of the intermediate channel steel spacing not exceeding 900mm is versatile and can cover most elevator shaft width requirements, reducing customized adjustments.

[0017] Furthermore, a supporting crossbeam is provided under the platform plate. The supporting crossbeam is a steel keel welded from 50mm*100mm*3mm rectangular tubes, and the steel keel is inserted into the groove of the channel steel. The platform plate is fixed by utilizing the concave structure of the channel steel in conjunction with the deformation and friction of the rubber. Attached Figure Description
