Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an elevator shaft operating platform. Background Technology

[0002] Elevators are commonly used vertical transportation tools in modern high-rise buildings. The elevator shaft of a high-rise building has an integral hollow structure. During construction, a construction platform needs to be set up inside the elevator shaft to facilitate the placement and dismantling of support formwork by construction personnel. In current construction, the construction platform is usually erected from the bottom of the basement using steel pipes, or by using I-beams to pass through the shaft walls and be fixed to the floor slab, with the operating platform erected on the I-beams using steel pipes.

[0003] For example, patent CN212802458U discloses a reusable derrick construction platform, including: a support base, comprising a base body and a support plate set on the base body, the base body including two parallel and spaced horizontal beams and at least two longitudinal beams welded between the two horizontal beams, the upper surface of the support plate forming an operating surface for workers to stand on, the width of the support plate being equal to the length of the longitudinal beams, and the support plate being welded and fixed to both the horizontal beams and the longitudinal beams; prefabricated scaffolding, including horizontal pipes, vertical pipes and longitudinal pipes, the horizontal pipes, vertical pipes and longitudinal pipes being fixedly connected together by fasteners to form a "well"-shaped frame; steel pipe fixing structures are respectively provided at the four corners of the support plate, the steel pipe fixing structures being used to fix the vertical pipes of the prefabricated scaffolding to fix the prefabricated scaffolding to the support base; the two ends of the horizontal beams are respectively used to be inserted into corresponding reserved holes opened in the concrete wall of the elevator shaft, and the horizontal beams can move back and forth along the axial direction of the reserved holes, and multiple reserved holes are spaced along the depth direction of the elevator shaft concrete wall.

[0004] The aforementioned derrick construction platform uses scaffolding supported by bases to erect the platform for construction. However, when using scaffolding to erect the platform, the erection height is relatively high, resulting in poor stability of the scaffolding, significant safety hazards, a long construction period, and inconvenient dismantling, making construction quite difficult. Summary of the Invention

[0005] The purpose of this invention is to provide an elevator shaft operating platform to solve the problems of existing construction platforms, such as high scaffolding height, poor stability, long construction period, inconvenient dismantling, and high construction difficulty.

[0006] To achieve the above objectives, the present invention provides an elevator shaft operating platform, comprising:

[0007] A wall-mounted device, wherein multiple wall-mounted devices are arranged at intervals on the wall of the elevator shaft, and each wall-mounted device is provided with a support groove on its top;

[0008] A support frame is provided and mounted on the wall-mounted device. The support frame is snapped into the support groove. The wall-mounted device also includes a limiting member that can be detachably assembled and disassembled into the groove of the support groove to press the support frame into the support groove.

[0009] A support plate is laid on the support frame and is used to support construction workers.

[0010] Preferably, the wall-mounting devices are arranged in pairs, and the paired wall-mounting devices are symmetrically arranged on opposite walls of the elevator shaft. The support grooves of the paired wall-mounting devices are collinear. The support frame includes multiple support pipes, and each support pipe is arranged in parallel at intervals. The axial ends of the support pipes are engaged with the support grooves of the paired wall-mounting devices.

[0011] Preferably, the support pipe has an overlapping section that passes through the support groove and overlaps the wall-mounted device, and the length of the overlapping section is greater than the gap between the overlapping section and the wall of the elevator shaft.

[0012] Preferably, the wall-mounted device includes a base and an upright plate. The base is provided with bolt holes for mounting expansion bolts connected to the elevator shaft. The upright plate is arranged on the top of the base, and two upright plates are arranged at intervals. The gap between the two upright plates forms the support groove. The limiting member is mounted on the top of the upright plate.

[0013] Preferably, the upright plate has a through hole, the limiting member is a fastening bolt assembled in the through hole, and the support frame is arranged between the fastening bolt and the base.

[0014] Preferably, the base includes a fixed plate, an assembly plate, and a reinforcing rib plate. The fixed plate and the assembly plate are arranged perpendicular to each other. The bolt holes are formed in the fixed plate. The upright plate is fixedly arranged in the assembly plate. The reinforcing rib plate is connected between the fixed plate and the assembly plate.

[0015] Preferably, there are at least two sets of reinforcing ribs, with each reinforcing rib arranged in parallel at intervals, and the bolt holes are arranged between adjacent reinforcing ribs.

[0016] Preferably, the support plate has a side wall surface that abuts against the upright plate in the horizontal direction.

[0017] Compared with existing technologies, the elevator shaft operating platform of this invention has the following advantages: multiple wall-mounted devices are spaced apart on the elevator shaft wall. These devices can be fixed to the shaft wall with expansion bolts to form the assembly base of the support frame. The support frame is clamped in the support groove of the wall-mounted device, and the support groove and limiting components are used to position the support frame and prevent it from shaking. The support plate is laid on the support frame for operators to carry out construction, thus improving the stability of the operating platform. The wall-mounted devices of this operating platform are directly fixed to the elevator shaft wall. The operating platform only needs to be set up on the floor where construction is required, eliminating the need for high scaffolding or other structures. When construction is carried out on the next floor, the operating platform can be set up on the corresponding floor, saving construction time, facilitating assembly and disassembly, and reducing construction costs.

Detailed Implementation

[0023] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0024] A preferred embodiment of the elevator shaft operating platform of the present invention, such as... Figures 1 to 4 As shown, the elevator shaft operating platform includes a wall-mounted device 1, a support frame 2, and a support plate 3. The wall-mounted device 1 serves as the fixed foundation for the elevator shaft operating platform, the support frame 2 is used to lay the support plate 3, and the support plate 3 is used to provide a support platform for construction personnel.

[0025] Multiple wall-mounted devices 1 are arranged at intervals on the elevator shaft wall 4. Each wall-mounted device 1 is fixedly assembled to the elevator shaft wall 4 using expansion bolts to secure the elevator shaft operating platform inside the elevator shaft. All wall-mounted devices 1 have the same structure, and each wall-mounted device 1 has a support groove 13 at its top for mounting a support frame 2. In this embodiment, based on the dimensions of the elevator shaft, the spacing between adjacent wall-mounted devices 1 on the same elevator shaft wall 4 is 300mm to ensure that the wall-mounted devices 1 provide sufficient support for the support frame 2.

[0026] The support frame 2 is supported on each wall-mounted device 1. The support frame 2 is clamped in the support groove 13. The multiple spaced wall-mounted devices 1 provide multi-point support for the support frame 2 through the support groove 13, ensuring the stability of the support frame 2. The support groove 13 can limit the position of the support frame 2 to prevent it from shaking on the wall-mounted device 1. At the same time, using the support groove 13 to clamp the support frame 2 also facilitates the assembly and disassembly of the support frame 2.

[0027] The wall-mounted device 1 also includes a limiting member 14, which is detachably assembled and disassembled at the opening of the support groove 13. The limiting member 14 is used to press the support frame 2 into the support groove 13. After the support frame 2 is installed in the support groove 13, the support groove 13 can limit the support frame 2 in the horizontal direction, and the limiting member 14 can limit the support frame 2 in the vertical direction, thereby ensuring that the support frame 2 is stably arranged on the wall-mounted device 1 and ensuring construction safety.

[0028] Support plate 3 is laid on top of support frame 2, providing standing space for construction workers. The support plate 3 is laid out, allowing it to be removed and reused after construction, significantly saving costs. Furthermore, installation and disassembly are simple, saving construction time. In this embodiment, support plate 3 is a plywood structure with a thickness of 18mm.

[0029] The wall-mounted device 1 of the elevator shaft operating platform can be fixedly assembled to the elevator shaft wall 4 using expansion bolts to form the assembly base of the support frame 2. The support frame 2 is locked in the support groove 13 of the wall-mounted device 1. The support groove 13 and the limiting member 14 are used to position the support frame 2 and prevent it from shaking. The support plate 3 is laid on the support frame 2 for operators to carry out construction, which improves the stability of the operating platform. In addition, in the later stage, the elevator shaft operating platform can also serve as a hard protection for the shaft, saving a lot of construction costs.

[0030] The wall-mounted device 1 of the operating platform is directly fixed to the elevator shaft wall 4. The operating platform only needs to be installed on the floor where construction is required, eliminating the need for tall scaffolding or other structures. When construction begins on the next floor, the operating platform can be installed on the corresponding floor, saving construction time, facilitating assembly and disassembly, and reducing construction costs.

[0031] Preferably, the wall-mounting devices 1 are arranged in pairs, and the paired wall-mounting devices 1 are symmetrically arranged on the opposite shaft walls 4 of the elevator shaft. The support grooves 13 of the paired wall-mounting devices 1 are arranged collinearly. The support frame 2 includes multiple support pipes 21, each support pipe 21 is arranged in parallel at intervals, and the axial ends of the support pipes 21 are engaged with the support grooves 13 of the paired wall-mounting devices 1.

[0032] The wall-mounted devices 1 are arranged in pairs and symmetrically on the elevator shaft wall 4, so that the support grooves 13 of the wall-mounted devices 1 can be collinear, allowing the axial ends of the support pipes 21 to be engaged in the support grooves 13. The support frame 2 is formed by multiple support pipes 21, with both ends of the support pipes 21 supported in the support grooves 13 of the wall-mounted devices 1, providing sufficient support force. At the same time, the structure of the support frame 2 is simplified, and each support pipe 21 can be disassembled and reassembled individually when installing and disassembling the wall-mounted devices 1, saving construction time.

[0033] In this embodiment, the support pipe 21 is a 48*3 steel pipe. Using a steel pipe as the support pipe 21 can ensure that the support frame 2 has sufficient strength to bear the weight of the construction personnel.

[0034] Preferably, the support pipe 21 has an overlapping section 211, which passes through the support groove 13 and overlaps with the wall attachment device 1. The length of the overlapping section 211 is greater than the gap between the overlapping section 211 and the wall 4 of the elevator shaft.

[0035] The overlapping section 211 of the support pipe 21 passes through the support groove 13. Since the length of the overlapping section 211 is greater than the gap between the overlapping section 211 and the wall 4 of the elevator shaft, the overlapping section 211 will not detach from the support groove 13 when the support pipe 21 expands or contracts axially, thus ensuring that the support pipe 21 will not slide out of the support groove 13 and ensuring construction safety.

[0036] Preferably, the wall-mounted device 1 includes a base 11 and a vertical plate 12. The base 11 is provided with bolt holes 114 for mounting expansion bolts connected to the elevator shaft. The vertical plate 12 is arranged on the top of the base 11. Two vertical plates 12 are arranged at intervals. The gap between the two vertical plates 12 forms a support groove 13. The limiting member 14 is mounted on the top of the vertical plate 12.

[0037] The wall-mounted device 1 is formed by a base 11 and two upright plates 12. A support groove 13 is formed by the gap between the two upright plates 12, which simplifies the structure of the support groove 13. The upright plates 12 can also limit the support rod, and at the same time, the upright plates 12 provide an assembly position for the limiting component 14. In this embodiment, the upright plate 12 is a rectangular plate structure, and the upright plate 12 is welded and fixed to the base 11.

[0038] Preferably, the upright plate 12 has a through hole 121, the limiting member 14 is a fastening bolt assembled in the through hole 121, and the support frame 2 is arranged between the fastening bolt and the base 11.

[0039] The limiting member 14 is formed by fastening bolts. The fastening bolts have high strength and are used to press the support tube 21. They can also be quickly installed and removed from the through hole 121 of the upright plate 12, saving construction time. In other embodiments, the limiting member 14 can also be a snap-on plate, which is fastened to the upright plate 12 to limit the support tube 21.

[0040] Preferably, the base 11 includes a fixing plate 111, an assembly plate 112 and a reinforcing rib plate 113. The fixing plate 111 and the assembly plate 112 are arranged perpendicular to each other. Bolt holes 114 are opened in the fixing plate 111. The upright plate 12 is fixedly arranged on the assembly plate 112. The reinforcing rib plate 113 is connected between the fixing plate 111 and the assembly plate 112.

[0041] The base 11 is formed by a fixed plate 111, an assembly plate 112, and a reinforcing rib 113. A right-angled steel plate structure is formed between the fixed plate 111 and the assembly plate 112. The reinforcing rib 113 connects the fixed plate 111 and the assembly plate 112, thereby increasing the load-bearing capacity of the base 11 and reinforcing it. In this embodiment, the reinforcing rib 113 has a triangular support structure, and the fixed plate 111, the assembly plate 112, and the reinforcing rib 113 are welded together.

[0042] Preferably, there are at least two sets of reinforcing ribs 113, with each reinforcing rib 113 arranged in parallel at intervals, and bolt holes 114 arranged between adjacent reinforcing ribs 113.

[0043] At least two sets of reinforcing ribs 113 are arranged in parallel and spaced apart to further enhance the load-bearing capacity of the base 11. In this embodiment, each wall-mounted device 1 has two reinforcing ribs 113 located at both ends of the base 11, and four bolt holes 114 are arranged in a rectangular interval to ensure the connection strength between the wall-mounted device 1 and the elevator shaft.

[0044] Preferably, the support plate 3 has a side wall surface, which abuts against the upright plate 12 in the horizontal direction.

[0045] The side wall of the support plate 3 abuts against the vertical plate 12, and the vertical plate 12 can be used to horizontally limit the support plate 3, prevent the support plate 3 from sliding on the support frame 2, and ensure construction safety.

[0046] The working process of this invention is as follows: When assembling the elevator shaft operating platform, installation is carried out according to the height of each construction floor. First, expansion bolts are used to install the fixing plate 111 of the wall-mounted device 1 on the shaft wall or the edge beam of the floor slab. The wall-mounted devices are installed symmetrically during installation. Then, the support pipe 21 is placed in the support groove 13 between the upright plates 12 of the wall-mounted device 1, and the fastening bolts pass through the through holes 121 on the upright plates 12 to fix the support pipe 21 to the wall-mounted device 1. According to the shaft size of the elevator shaft, each wall-mounted device 1 and support pipe 21 are installed with a spacing of 300mm, so that multiple support pipes 21 form a support frame 2. After installation, the support plate 3 is laid on the support frame 2 to form an operating platform. When installing the next floor, it is only necessary to stand on the already installed platform and use a high stool to install the next floor. When dismantling, it is dismantled from top to bottom.

[0047] In summary, this invention provides an elevator shaft operating platform with multiple wall-mounted devices spaced apart on the elevator shaft wall. These devices can be fixed to the shaft wall using expansion bolts to form the assembly base of a support frame. The support frame is secured within the support grooves of the wall-mounted devices, and the support grooves and limiting components are used to position the support frame, preventing it from swaying. A support plate is laid on the support frame for operators to work on, improving the stability of the operating platform. Since the wall-mounted devices are directly fixed to the elevator shaft wall, the operating platform only needs to be installed on the floor where construction is required, eliminating the need for high scaffolding or other structures. When construction begins on the next floor, the operating platform can be installed on the corresponding floor, saving construction time, facilitating assembly and disassembly, and reducing construction costs.

[0048] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
