Description

Technical Field

[0001] This utility model relates to the field of exterior wall construction technology, specifically to an exterior wall construction platform for civil engineering. Background Technology

[0002] Civil engineering generally refers to civil engineering projects, which include the planning, construction, and maintenance of all infrastructure related to water, soil, and culture. During civil engineering construction, construction platforms are usually erected at the exterior walls. When constructing on the exterior of low-rise buildings, platforms are typically erected to support people standing on them, which is a relatively stable and safe method. However, when dealing with high-rise buildings, only suspended platforms can be used, with the suspended platform serving as the construction platform for construction from top to bottom.

[0003] A search of the utility model patent with publication number CN221722247U reveals a construction platform for exterior walls in civil engineering. This platform effectively reduces swaying during the lowering of steel cables while ensuring the platform's vertical movement. Furthermore, when the platform sways due to wind, it increases friction with the building's exterior wall, effectively reducing the degree of swaying. However, it has certain shortcomings. High-rise buildings often have flat roofs, sometimes with parapet walls. While the drive unit is easily installed on flat roofs using mounting plates (with mounting holes and bolts), ensuring its load-bearing capacity, it is inconvenient to install the drive unit on roofs with parapet walls (parapet walls are typically used as fences, and drilling holes in the top is difficult, resulting in low load-bearing capacity). Therefore, this application proposes a construction platform for exterior walls in civil engineering. Utility Model Content

[0004] The purpose of this utility model is to address the fact that the existing suspended platform's fixing frame cannot be adjusted and installed according to flat roofs and parapet walls, which reduces its practicality. This utility model provides a civil engineering exterior wall construction platform.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A construction platform for exterior walls in civil engineering, comprising:

[0007] A door-shaped panel has ear plates at each of its four bottom corners. An angle plate connects the ear plates to the door-shaped panel. A first lead screw is threaded through one side of the door-shaped panel. A pressure plate is rotatably connected to the end of the first lead screw. A guide rod with its end sliding through the door-shaped panel is provided on the pressure plate.

[0008] The lifting platform component includes a mounting base set on a gantry plate, a shaft rotatably mounted on the mounting base, two winding drums fixed on the shaft, two pulleys on the mounting base, and steel wire ropes wound on both winding drums. The free ends of the two steel wire ropes are respectively wound around the two pulleys and connected to a suspended platform frame.

[0009] Furthermore, a worm gear is fixedly mounted on the shaft, a motor is mounted on the mounting base, and a worm gear that meshes with the worm gear is fixedly mounted on the output shaft of the motor.

[0010] Furthermore, the suspended platform includes a connecting frame connected to two steel wire ropes, a bearing plate is connected to one side of the connecting frame, and a railing is provided on the top of the bearing plate.

[0011] Furthermore, two mounting slots are provided on the side of the connecting frame away from the support plate, and several rubber wheels are arranged in an array for rotation within the mounting slots.

[0012] Furthermore, the upper and lower sides of the bearing plate are both connected to the connecting frame with support rods.

[0013] Furthermore, a groove is provided on the top of the portal plate, and a slider is provided on the mounting base that is slidably inserted into the groove. A second lead screw is rotatably passed through the portal plate, and the slider is threaded onto the second lead screw.

[0014] Furthermore, each of the top two ends of the connecting frame is equipped with a hanging ring, and each of the free ends of the two wire ropes is equipped with a hook, with the two hooks respectively engaging with the two hanging rings.

[0015] Furthermore, a ladder is installed on one side of the gate-shaped panel.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, the door-shaped panel can be fixed to the roof of a flat building by the ear plates at the four corners, or it can be fastened to the parapet wall. By twisting the first screw, the pressure plate is squeezed against the parapet wall, thereby fixing the door-shaped panel to the parapet wall. When fixing it to the parapet wall, there is no need to drill holes for installation, thus ensuring the overall load-bearing stability. The installation can be switched according to the actual situation, thereby improving practicality.

[0018] 2. In this utility model, by connecting the steel wire rope to the connecting frame, the steel wire rope is not connected to the center of the suspended platform. The connecting frame is located at the center of gravity. When a person stands on the bearing plate, the gravity will exert a lateral force on the connecting frame to press against the wall, making the connecting frame fit against the wall. Utilizing the friction of its fit against the wall, the suspended platform is not easy to sway during the lifting process or when affected by wind, thus making the entire suspended platform fit against the wall, thereby improving stability.

[0019] 3. In this utility model, by setting rubber wheels on the connecting frame, the rubber wheels roll in contact with the wall during the lifting and lowering process of the suspended basket frame, which not only ensures the smoothness of lifting and lowering, but also avoids damage to the wall. At the same time, when the suspended basket frame is not lifting and lowering and is in a fixed position, it can increase the friction between it and the wall, further reducing the swaying of the suspended basket frame, thereby improving its practicality.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] This embodiment provides a construction platform for exterior walls in civil engineering, mainly to solve the problem that the existing suspended platform's fixing frame cannot be adjusted and installed according to flat roofs and parapet walls, reducing its practicality. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-6 Please provide a detailed explanation:

[0029] A construction platform for exterior walls in civil engineering, comprising:

[0030] A portal-shaped panel 1 has ear plates 2 at each of its four bottom corners. Angle plates 3 connect the ear plates 2 to the portal-shaped panel 1. Preferably, mounting holes are drilled through the ear plates 2. The ear plates 2 can be fixed to the building roof using the mounting holes and bolts. When the building has a flat roof, the portal-shaped panel 1 is placed on the roof and fixed thereusing screws and mounting holes. A first threaded rod 4 is threaded through one side of the portal-shaped panel 1. A pressure plate 5 is rotatably connected to the end of the first threaded rod 4. A guide rod 6, the end of which slides through the portal-shaped panel 1, is provided on the pressure plate 5. When the building roof has a parapet wall, [the guide rod 6 is then inserted]. The portal panel 1 is fastened to the parapet wall and can be adjusted according to the thickness of the parapet wall. During adjustment, the first screw 4 is turned and rotated. Under the guidance of the guide rod 6, the pressure plate 5 cooperates with the portal panel 1 to clamp and resist the parapet wall. The frictional force of the contact is used to fix the portal panel 1. The inverted U-shaped structure of the portal panel 1 can be placed on a flat roof for fixation, or when the building roof has a parapet wall, it can be fastened to the parapet wall and clamped and fixed by the pressure plate 5 and the portal panel 1. The two fixing methods can be switched according to the actual situation of the building, thereby improving practicality.

[0031] The lifting platform component 7 includes a mounting base 701 mounted on a portal plate 1. A shaft 702 is rotatably mounted on the mounting base 701. Two winding drums 703 are fixed on the shaft 702. Two pulleys 704 are mounted on the mounting base 701. Steel wire ropes 705 are wound on both winding drums 703. The free ends of the two steel wire ropes 705 are respectively wound around the two pulleys 704 and connected to a suspended frame 706. When constructing the exterior wall, workers stand inside the suspended frame 706. The shaft 702 is driven to rotate by a drive unit, which in turn drives the two winding drums 703 to rotate. When the winding drums 703 release the rope, the suspended frame 706 is lowered. When the winding drums 703 rewind, the suspended frame 706 is raised, making the suspended frame 706 a lifting platform to meet the needs of exterior wall construction.

[0032] In this design, the portal panel 1 can be fixed to the roof of a flat building by the ear plates 2 at the four corners, or it can be fastened to the parapet wall. By twisting the first screw rod 4, the pressure plate 5 is driven to press against the parapet wall, thereby fixing the portal panel 1 to the parapet wall. When fixing it to the parapet wall, there is no need to drill holes for installation, thus ensuring the overall load-bearing stability.

[0033] like Figure 3 As shown, in this embodiment, a worm gear 8 is fixed on the shaft 702, and a motor 9 is installed on the mounting base 701. The output shaft of the motor 9 is fixed with a worm 10 that meshes with the worm gear 8. When the motor 9 does work, its output shaft drives the worm 10 to rotate. By utilizing the meshing of the worm 10 and the worm gear 8, the shaft 702 is driven to rotate. Through the arrangement of the worm gear 8 and the worm 10, the motor 9 is not directly connected to the shaft 702. By utilizing the characteristic that the worm gear 8 cannot drive the worm 10 to rotate, the overload protection of the motor 9 is achieved when the suspended basket 706 is fixed in a certain position.

[0034] like Figure 5 As shown, in this embodiment, the suspended platform 706 includes a connecting frame 7061 connected to two steel wire ropes 705. A bearing plate 7062 is connected to one side of the connecting frame 7061, and a railing 7063 is provided on the top of the bearing plate 7062. Preferably, the connecting frame 7061 is H-shaped. The two steel wire ropes 705 are respectively connected to the top two ends of the connecting frame 7061, and the bearing plate 7062 is connected to the middle section of the connecting frame 7061. Because the steel wire ropes 705 are connected to the connecting frame 7061, the steel wire ropes 705 are not connected to the center of the suspended platform 706. When the suspended platform 706 is in the air, the connecting frame 7061... 061 and the steel wire rope 705 remain vertical, and the connecting frame 7061 is located at the center of gravity. When a person stands on the bearing plate 7062, gravity will exert a lateral force on the connecting frame 7061 to compress the wall (because the bearing plate 7062 is off-center from the center of gravity, a person standing at any position on the bearing plate 7062 will exert a lateral force on the connecting frame 7061), causing the connecting frame 7061 to adhere to the wall. Utilizing the friction of its contact with the wall, the suspended platform 706 is less prone to swaying during lifting or when affected by wind, ensuring that the entire suspended platform 706 adheres to the wall, thus improving stability.

[0035] like Figure 5 As shown, in this embodiment, the connecting frame 7061 has two mounting slots 11 on the side away from the bearing plate 7062. Several rubber wheels 12 are arranged in an array for rotation within the mounting slots 11. By using the mounting slots 11 and the rubber wheels 12 within them, the frictional resistance between the suspended basket frame 706 and the wall is reduced during the lifting process. This not only ensures the smoothness of the lifting of the suspended basket frame 706 but also reduces frictional damage to the wall. The rubber material of the rubber wheels 12 ensures sufficient friction between the suspended basket frame 706 and the wall when the suspended basket frame 706 is not lifting (this friction refers to reducing the degree of swaying when the suspended basket frame 706 is fixed), thus improving stability.

[0036] like Figure 5As shown, in this embodiment, both the upper and lower sides of the bearing plate 7062 are connected to the connecting frame 7061 with support rods 13, as shown. Figure 5 As shown, the two lower support rods 13 support the bearing plate 7062, and the two upper support rods 13 pull the bearing plate 7062, thereby improving the connection strength between the bearing plate 7062 and the connecting frame 7061 and improving stability.

[0037] like Figure 4 As shown, in this embodiment, a groove 14 is provided on the top of the portal plate 1, and a slider 15 is provided on the mounting base 701, which is slidably inserted into the groove 14. A second lead screw 16 is rotatably passed through the portal plate 1, and the slider 15 is threaded onto the second lead screw 16. Since the portal plate 1 can be installed on a flat roof or on a parapet wall, there is a misalignment between the two positions. Through the sliding cooperation of the groove 14 and the slider 15, the second lead screw 16 can be twisted to adjust the horizontal sliding of the mounting base 701. This allows the connecting frame 7061 to effectively fit against the wall after the portal plate 1 is fixed and the wire rope 705 pulls it, further reducing the overall swaying of the suspended frame 706 and improving its stability.

[0038] like Figure 6 As shown, in this embodiment, hanging rings 17 are installed at both ends of the top of the connecting frame 7061, and hooks 18 are installed at the free ends of the two wire ropes 705. The two hooks 18 are hooked and engaged with the two hanging rings 17 respectively. Through the hooking and engaging of the hooks 18 and the hanging rings 17, the suspended basket frame 706 and the door-shaped plate 1 can be disassembled and separated as a whole, which is convenient for transportation and transfer.

[0039] like Figure 1 and Figure 3 As shown in this embodiment, a ladder 19 is installed on one side of the portal plate 1. Since the wire rope 705 is connected to the connecting frame 7061, there is a certain drop between the bearing plate 7062 and the roof of the building. By installing the ladder 19, it is convenient for workers to enter the suspended basket 706 from the roof, or to climb up to the roof from inside the suspended basket 706, making it more convenient for workers to carry out construction.

[0040] The workflow of this utility model is as follows: During exterior wall construction, the portal panel 1 is fixed to the roof. When the roof is a flat structure, the portal panel 1 is placed directly on the roof, and fixed to the roof through the mounting holes on the ear plate 2 using drilling and screws. When the roof has a parapet wall, the portal panel 1 is snapped onto the parapet wall. Twisting the first screw rod 4 causes the pressure plate 5 to press against the parapet wall, thereby fixing the portal panel 1 to the parapet wall. No drilling is required when fixing it to the parapet wall, thus ensuring the overall load-bearing stability. After the portal panel 1 is fixed, the connecting bracket 7061 fits in place. On the wall, the motor 9 drives the shaft 702 to rotate, which in turn drives the winding drum 703 to rotate, causing the wire rope 705 to lift the connecting frame 7061. Since the wire rope 705 is connected to the connecting frame 7061, the bearing plate 7062 is off-center from the center of gravity. When a worker stands on the bearing plate 7062, gravity will exert a lateral force on the connecting frame 7061 to compress the wall. Using this lateral force, the suspended frame 706 will fit snugly against the wall and will not sway due to the different positions of the people or the influence of wind, thus improving its practicality.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
