Description

[0001] This application claims priority to Chinese Patent Application No. 202422324944.6, filed on September 24, 2024, entitled "Elevator Shaft Operation Platform for High-Rise Buildings", the entire contents of which are incorporated herein by reference and are hereby declared. Technical Field

[0002] This utility model relates to the field of building construction technology, and in particular to an elevator shaft operation platform for high-rise buildings. Background Technology

[0003] Elevator shafts are widely used in industrial, civil, and public buildings. The main function of an elevator shaft work platform is to facilitate the erection, reinforcement, and dismantling of elevator shaft wall formwork.

[0004] When constructing elevator shafts on-site, there is no standard structure for the working platform. Existing technologies typically use steel pipes or angle steel welded into a triangular support structure for the working platform. Figure 1 As shown in the image. During the installation of this type of work platform inside the elevator shaft, workers need to stand at the elevator entrance and wait for the tower crane to lift the work platform to the corresponding floor. The workers then support the bottom support point of the triangular bracket structure of the work platform on the side of the elevator opening floor slab, forming mutual support with the upper support point of the triangular bracket structure of the work platform. This type of work platform has significant safety hazards, as its load-bearing capacity and sturdiness are insufficient. Utility Model Content

[0005] In view of this, the present invention provides an elevator shaft working platform for high-rise buildings, which ensures the support stability and reliability of the platform body, enhances the load-bearing capacity of the platform body, and improves the safety of workers.

[0013] The lifting ring or hook is welded to the platform panel.

[0014] Optionally, the support leg includes a support column and a baffle connected together. The support column is provided with a positioning hole for installing a positioning pin. The distance between the positioning hole and the baffle is the same as the thickness of the wall. The positioning pin is inserted into the positioning hole.

[0015] Optionally, the axis of the positioning hole is perpendicular to the side of the support column, and the axis of the positioning hole is parallel to the support surface of the support leg.

[0016] Optionally, the length of the support column is the sum of the wall thickness and the set support length, wherein the set support length is not less than 300mm.

[0017] Optionally, the width of the baffle is greater than the width of the support column, and the height of the baffle is greater than or equal to the height of the support column.

[0037] This utility model discloses an elevator shaft working platform for high-rise buildings, which ensures the support stability and reliability of the platform body, enhances the load-bearing capacity of the platform body, and improves the safety of workers.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] See Figures 2 to 13 This utility model discloses an elevator shaft working platform for high-rise buildings, comprising a platform body 2 and support legs 1 for supporting the platform body 2. To improve the stability of the support for the platform body 2, multiple support legs 1 are provided, which are inserted into the walls 5 surrounding the elevator shaft 3. Here, "multiple" refers to at least three. The supporting ends of the support legs 1 extend through the walls 5 into the cavity of the elevator shaft 3.

[0040] In this configuration, the support surfaces of the different support legs 1 are located on the same horizontal plane, thus ensuring the stability of the platform body 2. The platform body 2 is placed on the support surfaces of the support legs 1, as shown below. Figure 2 As shown. The supporting surface of support leg 1 refers to the upper surface of support leg 1 in its installed state. Support leg 1 can be made of I-beams.

[0041] This utility model discloses an elevator shaft work platform for high-rise buildings. The platform body 2 is supported by support legs 1 inserted into the wall 5, ensuring the stability and reliability of the platform body 2, enhancing its load-bearing capacity, improving worker safety, and reducing the risk of falls. During platform body 2 installation, workers do not need to approach the elevator door opening. The support legs 1 are all located within the walls 5 on both sides of the elevator shaft opening. The platform body 2 is hoisted down and placed directly on the support legs 1, eliminating the need for workers to assist in placement on the floor slab 4 next to the elevator shaft opening. This improves installation safety and saves manpower. This utility model of an elevator shaft work platform for high-rise buildings improves the safety of elevator shaft construction and installation, is reusable, and saves costs.

[0042] Specifically, the platform body 2 includes a platform support frame 203 and a platform panel 201, such as... Figure 5 and Figure 6 As shown, the platform panel 201 is welded to the upper surface of the platform support frame 203, which is a frame made of welded profiles. In one embodiment, the platform support frame 203 is a star-shaped frame, such as... Figure 7 As shown. In another embodiment, the platform support frame 203 is a grid-shaped frame, as shown. Figure 8 As shown.

[0043] To facilitate the assembly and disassembly of the platform body 2, multiple lifting structures 202 are fixedly connected to the platform panel 201, and the multiple lifting structures 202 are evenly distributed around the center of the platform panel 201. In one embodiment, such as Figure 5 As shown, four lifting structures 202 are provided. Specifically, the lifting structure 202 is a lifting ring or hook, which facilitates the lifting of the platform body 2. Furthermore, the lifting ring or hook is welded to the platform panel 201. The lifting ring or hook can also be connected to the platform panel 201 by other connection methods commonly used in the art, such as bolt connection, which is not limited here.

[0044] Furthermore, the support leg 1 includes a support column 103 and a baffle 101 connected together, such as Figures 9 to 12 As shown. The baffle 101 is welded to one end of the support column 103, this end being away from the supporting end of the support column 103. To position the support column 103 inserted into the wall 5, the support column 103 is provided with a positioning hole 102 for installing the positioning pin 6. The distance between the positioning hole 102 and the baffle 101 is the same as the thickness of the wall 5, as shown. Figure 13As shown, the positioning pin 6 is inserted into the positioning hole 102, thereby ensuring the reliability of the position of the support leg 1 inserted into the wall 5. It is understood that the wall 5 is provided with a wall hole for inserting the support column 103, and the wall hole corresponds to the cross-section of the support column 103, facilitating the insertion of the support column 103 into the wall hole. A limiting member 7 is inserted into the shaft end of the positioning pin 6. The limiting member 7 can be a cotter pin or other commonly used limiting structure. The size of the baffle 101 is larger than the size of the connecting end of the support column 103 to facilitate the limiting of the support leg 1 when inserted into the wall 5.

[0045] The positioning hole 102 is perpendicular to the side of the support column 103, and the positioning hole 102 is parallel to the support surface of the support leg 1. The support surface of the support leg 1 is the upper surface of the support column 103.

[0046] To improve the reliability of the support, the length of the support column 103 is the sum of the thickness of the wall 5 and the set support length, such as... Figure 13 As shown in the figure, the length of the support column 103 located on the right side of the wall 5 is the set support length, which is not less than 300mm. In one embodiment, the set support length is 350mm.

[0047] In one embodiment, the width of the baffle 101 is greater than the width of the support column 103, such as... Figure 12 As shown, the width of the support column 103 is W2, wherein one side of the baffle 101 extends beyond the edge of the support column 103 by a first dimension W1 along the width direction, and the first dimension W1 is at least 100 mm. The height dimension H of the baffle 101 is greater than or equal to the height dimension of the support column 103. In one embodiment, as... Figure 9 As shown, the height H of the baffle 101 is greater than the height of the support column 103. In another embodiment, as... Figure 10 and Figure 11 As shown, the height dimension H of the baffle 101 is equal to the height dimension of the support column 103.

[0048] To facilitate pulling the support leg 1, a handle 104 is fixedly connected to the surface of the baffle 101 away from the support column 103, and the handle 104 is welded to the baffle 101.

[0049] In one specific embodiment, the support column 103 is a No. 16 I-beam, the platform support frame 203 is welded from No. 8 channel steel, and the baffle 101 is a steel plate with a thickness of 6mm. Four support legs 1 are provided.

[0050] The manufacturing process of platform body 2: First, measure the net width and net length of the inner wall 5 of elevator shaft 3 to determine the dimensions. Platform body 2 is 50mm smaller on each side than the net dimensions of elevator shaft 3 to facilitate installation. After the channel steel is spliced, weld the channel steel to form platform support frame 203. Platform panel 201 is made of checkered steel plate and is welded to the top of platform support frame 203. After welding, weld lifting rings onto platform panel 201; the diameter of the lifting ring holes is 150mm. Platform body 2 is now complete.

[0051] Manufacturing process of support leg 1: I-beams are cut into support columns 103 according to the set dimensions. Steel plates are cut into rectangles with dimensions referring to the set dimensions, and then cut into baffles 101. One end of the cut support column 103 is welded to the baffle 101. After welding, a semi-circular handle 104 is welded onto the baffle 101 for easy installation and turnover.

[0052] This utility model relates to an elevator shaft work platform for high-rise buildings. The work platform can be mass-produced using common building materials, resulting in low cost, easy assembly and disassembly, and multiple reuses, thus improving construction safety.
