Description

Technical Field

[0001] This utility model relates to the field of building exterior wall technology, specifically a working platform for building exterior walls. Background Technology

[0002] Building exterior wall work platforms can replace traditional scaffolding and other equipment, significantly improving the safety of high-altitude operations, reducing accident risks, while also increasing work efficiency, shortening the construction period and reducing labor costs. In exterior wall construction, high-altitude work platforms can provide a stable working platform, enabling workers to safely carry out various construction operations at heights, such as paint spraying and tile pasting.

[0003] For example, the authorization announcement number "CN212478457U" is named a building construction exterior wall painting operation platform. The support rod can be moved out from the inside of the storage slot and slide down along the first support frame and the second support frame to contact the ground. Under the support of the two sets of limit sleeves and support rods, the stability of the first support frame and the second support frame is increased, avoiding the need for additional additions after the existing stable support structure is assembled. However, the building construction exterior wall painting operation platform is relatively high in overall height, and the various components form a relatively complete whole. After being used on one construction site, it usually needs to be transported to another construction site. The large size and components will cause more inconvenience during disassembly and transportation.

[0004] Meanwhile, existing exterior wall painting work platforms for building construction have low safety because the bottom of the work platform is supported by wheels and the overall work platform is relatively long and thin. Workers need to perform painting work at high altitudes, and the long and thin exterior wall work platform supported by wheels is not stable enough. Workers and construction materials are prone to falling, resulting in low safety of exterior wall painting work platforms for building construction. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of existing exterior wall painting work platforms for building construction. After use at one construction site, most of them need to be transported to another construction site. The excessive size and components cause more inconvenience during disassembly and transportation. In addition, the slender exterior wall work platform supported by wheels is not stable enough, and workers and construction materials are prone to falling, which is unsafe to use. Therefore, a work platform for exterior wall painting in building construction is proposed.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Design a working platform for building exterior walls, including a base plate, anti-blocking blocks and a top plate. Multiple anti-blocking blocks are fixedly installed at the bottom of the base plate. A working platform splicing and assembly structure is provided above the base plate. A fall prevention structure for high-altitude operations on exterior walls is provided above the top plate.

[0008] Preferably, the work platform assembly structure includes insert strips and vertical plates. Two insert strips are movably inserted into the inner side of the base plate, and vertical plates are fixedly connected to the top ends of the two insert strips. Tenon blocks are fixedly connected to the side walls of the insert strips, and positioning rods are movably inserted into the top ends of the two vertical plates.

[0009] This setup utilizes an insert strip to drive the upper vertical plate vertically into the groove reserved on the side of the bottom plate. The insert strip can also be engaged with the tenon and mortise structure carved on the inner side of the bottom plate through a tenon and mortise block that protrudes and is fixed on one side. The vertical plate, bottom plate and top plate form a vertical frame structure, allowing workers to go up to the top plate to carry out exterior wall painting or tiling work.

[0010] Preferably, the two tenon blocks are engaged inside the base plate, the top of the vertical plate is movably connected to a top plate, and the inner side of the top plate is slidably connected to multiple positioning rods.

[0011] This setup allows the positioning rod to be pulled out upwards after the work is completed, separating the top plate and the vertical plate. Then, the insert strip can be slowly hammered out horizontally to separate the tenon block from the bottom plate. In this way, the entire building exterior wall working platform is divided into several different structural components.

[0012] Preferably, the side wall of the vertical plate is provided with an auxiliary support structure for the working platform. The auxiliary support structure for the working platform includes a main beam and overlapping blocks. Multiple overlapping blocks are connected to the side wall of the vertical plate by bolts and threads. The main beam is fixedly connected to the middle position of the overlapping blocks. Multiple secondary beams are fixedly connected to both sides of the main beam. The other end of the multiple secondary beams is fixedly connected to the overlapping blocks.

[0013] This system features multiple overlapping blocks connected to the side wall of the vertical plate via bolts. The overlapping blocks connect the horizontally welded main beams to the vertically installed vertical plate using bolt tightening. The parallel main beams on both sides are made of high-strength stainless steel plates. The main beams extend diagonally to the upper and lower sides as secondary beams to share the pressure and tension. The secondary beams are also fixed to the side wall of the vertical plate using overlapping blocks. The main beams and secondary beams provide stable support and reinforcement for the external wall working platform.

[0014] Preferably, the fall protection structure for working at height on the exterior wall includes a work platform and railings. The work platform is fixedly connected to the top of the ceiling, and multiple railings are fixedly connected to both sides of the top of the work platform. The top sidewalls of the multiple railings are fixedly connected to blocking bars.

[0015] This setup features a work surface made of non-slip, high-load-bearing metal steel plate. The work surface supports workers operating on the exterior wall and can also bear the weight of building materials and tools. Vertical railings protrude and are fixed on both sides of the work surface, with welded and fixed stop bars. The stop bars, together with the railings, provide workers with a safety barrier, reducing the risk of people and materials falling.

[0016] Preferably, a ladder frame is movably connected to the upper two sides of the base plate, and multiple ladder steps are fixedly connected to the inner side of the ladder frame. The tops of the two ladder frames are movably abutted against the lower inner side of the top plate.

[0017] This feature includes multiple horizontal ladder steps installed in the middle of the ladder frame to facilitate workers' access. With these ladder steps, accessing the ceiling at higher elevations becomes more stable and safer.

[0018] The utility model proposes a construction platform for exterior walls, which has the following advantages: the insert bar can drive the upper vertical plate to be vertically inserted into the groove reserved on the side of the bottom plate, and the insert bar can be engaged with the tenon and mortise structure carved on the inner side of the bottom plate through the tenon and mortise block fixed on one side. The vertical plate, bottom plate and top plate form a vertical frame structure. Workers can go up to the top plate to do exterior wall painting or tiling work. After the work is completed, the positioning rod can be pulled out upwards to separate the top plate and the vertical plate. Then, the insert bar can be slowly hammered out horizontally outwards to separate the tenon and mortise block from the bottom plate. In this way, the entire construction platform for exterior walls is divided into several different structural components, which makes it more convenient for manual and vehicle transportation.

[0019] The work surface is made of non-slip, high-load-bearing metal steel plate. The work surface supports workers' operations on the exterior wall and can also bear the weight of building materials and tools. The railings protrude vertically on both sides of the work surface and are fixed with welded guardrails. The guardrails, together with the railings, provide workers with a safety protection and reduce the risk of people and materials falling. Multiple ladder steps are installed horizontally in the middle of the ladder frame to facilitate workers' access. With the ladder steps, it is more stable and safe for workers to go up and down the ceiling at high places. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] Example 1:

[0029] Please see Figure 1-6 In this embodiment, a working platform for building exterior walls includes a base plate 1, anti-blocking blocks 2, and a top plate 3. Multiple anti-blocking blocks 2 are fixedly installed at the bottom of the base plate 1. The anti-blocking blocks 2 are made of multiple metal steel strips vertically welded to the lower end of the base plate 1. The anti-blocking blocks 2 can be inserted into the ground soil to increase the support force at the lower end of the base plate 1. A working platform splicing and assembly structure 4 is provided above the base plate 1, and a fall prevention structure 6 for high-altitude operations on exterior walls is provided above the top plate 3.

[0030] The work platform assembly structure 4 includes insert strips 41 and vertical plates 43. The two insert strips 41 are movably inserted into the inner side of the base plate 1. The insert strips 41 can drive the upper vertical plate 43 to be vertically inserted into the pre-reserved groove on the side of the base plate 1. Furthermore, the insert strips 41 can be engaged with the mortise and tenon structure carved on the inner side of the base plate 1 through a protruding tenon block 42 on one side. After installation, the vertical plates 43 stand vertically on both sides above the base plate 1. A prefabricated top plate 3 can be placed on top of the vertical plates 43. The worker then inserts a relatively long vertical metal positioning rod 44 between the vertical plates 43 and the top plate 3. The positioning rod 44 can lock the relative position between the top plate 3 and the vertical plate 43. Then, the vertical plate 43, the bottom plate 1 and the top plate 3 form a vertical frame structure. Workers can go up to the top plate 3 to carry out exterior wall painting or tiling work. The top of the two insert strips 41 are fixedly connected to the vertical plate 43, and the side wall of the insert strips 41 is fixedly connected to the tenon block 42. The top of the two vertical plates 43 are movably inserted with the positioning rod 44. The two tenon blocks 42 are snapped into the inside of the bottom plate 1. The top of the vertical plate 43 is movably connected to the top plate 3. The inner side of the top plate 3 is slidably connected to multiple positioning rods 44.

[0031] The side wall of the vertical plate 43 is provided with an auxiliary support structure 5 for the working platform. The auxiliary support structure 5 includes a main beam 51 and overlapping blocks 53. Multiple overlapping blocks 53 are connected to the side wall of the vertical plate 43 by bolts. The overlapping blocks 53 can connect the horizontally welded main beam 51 to the vertically installed vertical plate 43 by tightening the bolts. The parallel main beams 51 on both sides are made of high-strength stainless steel metal plates. The main beams 51 extend obliquely on the upper and lower sides to distribute the pressure and tension of the secondary beams 52. The secondary beams 52 are also fixed to the side wall of the vertical plate 43 by overlapping blocks 53. The main beams 51 and secondary beams 52 can provide stable support and reinforcement for the external wall working platform. The main beam 51 is fixedly connected to the middle position of the overlapping block 53. Multiple secondary beams 52 are fixedly connected to both sides of the main beam 51. The other end of the multiple secondary beams 52 is fixedly connected to the overlapping block 53.

[0032] The fall protection structure 6 for high-altitude operations on the exterior wall includes a work platform 61 and railings 62. The work platform 61 is fixedly connected to the top plate 3. The work platform 61 is made of anti-slip, high-load-bearing metal steel plate. The work platform 61 is used to support the workers' operations on the exterior wall and can also bear the weight of building materials and tools. Multiple railings 62 are fixedly connected to the top two sides of the work platform 61. The railings 62 protrude vertically from both sides of the work platform 61 and are fixedly connected to the guardrails 62. The guardrails 62 are connected to and welded to the blocking rods 63. The blocking rods 63, together with the railings 62, can provide a safety protection for the workers and reduce the risk of personnel and materials falling. The top side walls of the multiple railings 62 are fixedly connected to the blocking rods 63.

[0033] The upper sides of the base plate 1 are movably connected with ladder frames 71. Multiple ladder steps 72 are horizontally installed in the middle of the ladder frames 71 to facilitate the movement of workers up and down. With the ladder steps 72, the movement of workers up and down the top plate 3 at higher levels is more stable and safer. Multiple ladder steps 72 are fixedly connected to the inner side of the ladder frames 71. The tops of the two ladder frames 71 are movably abutted against the inner side of the bottom of the top plate 3.

[0034] Working principle:

[0035] Building exterior wall work platforms can be installed at the lower end of the exterior walls in the building construction field, and can effectively help with painting, aluminum panel installation or exterior wall tiling of some low-rise buildings.

[0036] Insertion strip 41 can drive the upper vertical plate 43 to be vertically inserted into the groove reserved on the side of the bottom plate 1. Insertion strip 41 can be engaged with the tenon structure carved on the inner side of the bottom plate 1 through the tenon block 42 protruding and fixed on one side. After installation, the vertical plate 43 stands vertically on both sides above the bottom plate 1. The prefabricated top plate 3 can be placed on the top plate 43. The workers then insert the relatively long metal steel structure positioning rod 44 between the vertical plate 43 and the top plate 3. The positioning rod 44 can lock the relative position between the top plate 3 and the vertical plate 43. Then the vertical plate 43, the bottom plate 1 and the top plate 3 form a vertical frame structure. Workers can go up to the top plate 3 to carry out building exterior wall painting or tiling work.

[0037] After the work is completed, the positioning rod 44 can be pulled out upwards to separate the top plate 3 and the vertical plate 43. Then, the insert strip 41 can be slowly hammered out horizontally outwards to separate the tenon block 41 from the bottom plate 1. In this way, the entire building exterior wall working platform is divided into several different structural components, which makes it more convenient for manual and vehicle transportation.

[0038] Multiple overlapping blocks 53 are connected to the side wall of the vertical plate 43 by bolt threads. The overlapping blocks 53 can connect the horizontally welded main beam 51 to the vertically installed vertical plate 43 by tightening the bolts. The parallel main beams 51 on both sides are made of high-strength stainless steel metal plates. The main beams 51 extend obliquely on the upper and lower sides to distribute the pressure and tension of the secondary beams 52. The secondary beams 52 are also fixed to the side wall of the vertical plate 43 by overlapping blocks 53. The main beams 51 and secondary beams 52 can provide stable support and reinforcement for the external wall working platform.

[0039] The work surface 61 is made of non-slip, high-load-bearing metal steel plate. The work surface 61 is used to support the workers' external wall operation and can also bear the weight of building materials and tools. The railing 62 protrudes vertically and is fixed on both sides of the work surface 61. The railing 62 is welded and fixed with the blocking bar 63. The blocking bar 63, together with the railing 62, can provide workers with a safety protection and reduce the risk of personnel and materials falling. The ladder frame 71 has multiple ladder steps 72 installed horizontally in the middle to facilitate workers to go up and down. With the ladder steps 72, it is more stable and safer for personnel to go up and down the top plate 3 at a high place.

[0040] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
