Abstract
Description
Technical Field
[0001] This invention relates to a prefabricated construction platform, belonging to the field of building construction. Background Technology
[0002] Prefabricated construction refers to the transfer of a large amount of on-site work from traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. Prefabricated buildings mainly include precast concrete structures, steel structures, and modern wood structures. Because they employ standardized design, factory production, assembly-based construction, information management, and intelligent applications, they represent modern industrialized production methods.
[0003] There are two construction methods for prefabricated buildings: semi-prefabricated and fully prefabricated. Semi-prefabricated buildings have a lower degree of prefabrication. Not all building components are prefabricated; some need to be constructed on-site. Major components such as beams, columns, and stair platforms require prefabrication, while less critical components like brick walls need to be built on-site. Semi-prefabricated buildings can save on transportation costs and have lower investment in production facilities, resulting in certain economic benefits. For construction projects located far from prefabrication plants or with inconvenient transportation, while semi-prefabricated construction is less efficient than fully prefabricated construction, it may be less expensive.
[0004] The construction sequence for semi-prefabricated buildings is as follows: construction proceeds from bottom to top, layer by layer. Each floor first constructs its main frame structure using beams and columns, then installs the staircase for that floor, and so on, building upwards layer by layer. When installing the staircase on each floor, the floor below may not yet have been poured or have its floor slab installed, making it inconvenient for construction workers to assemble the prefabricated staircase. Furthermore, since the lower-level staircase has already been installed, there is no suitable flat surface for erecting scaffolding, making climbing difficult for workers. Additionally, the lack of footholds for working at heights poses certain construction risks. Summary of the Invention
[0005] To address the problems existing in the prior art, this invention provides a prefabricated construction platform that is installed according to the staircase installation environment, providing effective support for construction workers to climb and stand during construction.
[0006] The technical solution adopted by this invention is a prefabricated construction platform, comprising two sets of construction platform groups arranged at intervals; one set of construction platform groups includes an upper construction platform and a sloping platform, and the other set of construction platform groups includes an upper construction platform; the upper construction platform is installed on the upper part of the upper crossbeam of the stairwell in the building, and one end of the sloping platform is connected to the upper construction platform and is set at an obtuse angle with the upper construction platform; the upper construction platform is an L-shaped bent plate, and the lower part of the upper construction platform has a sliding plate, which slides within the bent opening of the upper construction platform; there is a connecting bolt between the sliding plate and the upper construction platform, and the connecting bolt passes through the sliding plate and the upper construction platform and is threadedly connected to the upper construction platform; the interior of the bent opening of the upper construction platform, the sliding plate, and the connecting bolt surround the upper crossbeam and are relatively fixed to the upper crossbeam.
[0007] The optimized prefabricated construction platform described above has a rectangular frame and a metal mesh frame. The metal mesh frame is installed inside the rectangular frame and welded and fixed to the rectangular frame. One end of the rectangular frame is pivotally connected to the end of the upper construction platform.
[0008] The optimized prefabricated construction platform described above has a number of parallel, spaced horizontal bars, with both ends of the horizontal bars fixedly welded to the two sides of the rectangular frame.
[0009] The optimized prefabricated construction platform described above has a sloping platform with threaded struts that pass through the sloping platform and are threadedly connected to it.
[0010] In the optimized prefabricated construction platform described above, the sliding plate is an L-shaped bent metal plate; one of the bent surfaces of the upper construction platform is a fixed surface and is attached to the upper surface of the upper crossbeam, while the other bent surface of the upper construction platform is a protective surface; one of the bent surfaces of the sliding plate is a sliding surface and is attached to the fixed surface of the upper construction platform and slidably disposed thererelly, while the other bent surface of the sliding plate is a second sliding surface; the protective surface of the upper construction platform and the second sliding surface of the sliding plate are respectively attached to both sides of the upper crossbeam; the connecting bolt is located below the upper crossbeam, and the connecting bolt passes through the protective surface of the upper construction platform and the second sliding surface of the sliding plate and is threadedly connected to the protective surface of the upper construction platform.
[0011] In the optimized version of the prefabricated construction platform, the lower end of the fixed surface of the upper construction platform extends downward to the outer surface of the beam below the upper beam.
[0012] In the optimized version of the prefabricated construction platform, one side of the upper construction platform has a baffle, which is perpendicular to the upper construction platform and formed by bending one side of the upper construction platform; the baffles of the two sets of construction platform groups are arranged opposite to each other and parallel.
[0013] In the optimized prefabricated construction platform, the upper end of the baffle has a guide plate, which is pivotally connected to the upper end of the baffle; the guide plates of the two sets of construction platform sets form a V-shaped guide groove.
[0014] In the optimized prefabricated construction platform described above, the baffle has several positioning bolts, which pass through the baffle and are threadedly connected to it.
[0015] In the optimized version of the prefabricated construction platform, a central bending platform is constructed in the middle section of the sloping platform. The central bending platform is connected to a central tread, and one end of the central tread is connected to the central bending platform by bolts.
[0016] The beneficial effects of this application are as follows: The technical solution of this application is simple to operate and securely installed according to the installation environment of the stair slab.

Attached Figure Description
[0017] Figure 1 This is a schematic diagram of the structure of this application;
[0018] Figure 2 for Figure 1 AA section view;
[0019] Figure 3 This is a schematic diagram of another embodiment of the present application. Detailed Implementation
[0020] The technical features of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0021] As shown in the figure, the present invention is a prefabricated construction platform, comprising two sets of construction platform groups arranged at intervals. The two sets of construction platform groups are respectively installed on both sides of the location of the stair slab to be installed, so as to facilitate construction personnel to carry out construction operations from both sides.
[0022] One set of construction platform assemblies includes an upper construction platform 1 and a sloping platform 3, while the other set includes an upper construction platform 1. Both sets of upper construction platforms 1 are installed on either side of the upper end of the stair slab to be installed, providing a platform for construction workers to stand on and facilitating adjustment of the stair slab's installation position from both sides. Only one sloping platform 3 is required, used by construction workers for climbing and serving as a passageway to the upper construction platform 1.
[0023] As shown in the figure, the upper construction platform 1 is installed on the upper part of the upper beam 4 in the stairwell of the building. The upper construction platform 1 is an L-shaped bent plate, and the lower part of the upper construction platform 1 has a sliding plate 101, which slides within the bent opening of the upper construction platform 1. A connecting bolt 5 is provided between the sliding plate 101 and the upper construction platform 1, and the connecting bolt 5 passes through the sliding plate 101 and the upper construction platform 1 and is threadedly connected to the upper construction platform 1. The interior of the bent opening of the upper construction platform 1, the sliding plate 101, and the connecting bolt 5 surround the upper beam 4 and are fixed relative to the upper beam 4.
[0024] As shown in the figure, the sliding plate 101 is an L-shaped bent metal plate. One of the bent surfaces of the upper construction platform 1 is a fixed surface and is attached to the upper surface of the upper crossbeam 4. The other bent surface of the upper construction platform 1 is a protective surface. One of the bent surfaces of the sliding plate 101 is a sliding surface and is attached to the fixed surface of the upper construction platform 1 and is slidably set relative to it. The other bent surface of the sliding plate 101 is a second sliding surface.
[0025] Several U-shaped clamps are constructed on the lower part of the fixed surface of the upper construction platform 1. The two ends of the clamps are welded and fixed to the upper construction platform 1. The sliding surface of the sliding plate 101 is inserted into the U-shaped opening of the clamp, and the clamps restrict the range of movement of the sliding surface of the sliding plate 101. In order to prevent the sliding surface of the sliding plate 101 from detaching from the clamp, a limiting bolt can be set on the sliding surface of the sliding plate 101. The limiting bolt passes through the sliding surface of the sliding plate 101 and is threadedly connected to the sliding surface of the sliding plate 101. The clamp is located between the limiting bolt and the sliding surface.
[0026] Multiple threaded holes can be designed at different positions on the sliding surface of the sliding plate 101. As shown in the figure, during installation, the distance between the protective surface of the upper construction platform 1 and the sliding surface of the sliding plate 101 is adjusted according to the width of the upper crossbeam. Then, according to the distance between the protective surface of the upper construction platform 1 and the sliding surface of the sliding plate 101, the limiting bolts are installed in the corresponding threaded holes, so that the limiting bolts are located between the two clamps and fit against one of the clamps, which helps to limit and fix the distance between the protective surface of the upper construction platform 1 and the sliding surface of the sliding plate 101. When the connecting bolts 5 are not installed, it prevents the distance between the protective surface of the upper construction platform 1 and the sliding surface of the sliding plate 101 from changing.
[0027] The protective surface of the upper construction platform 1 and the sliding surface of the sliding plate 101 are respectively attached to both sides of the upper crossbeam 4. The connecting bolt 5 is located below the upper crossbeam 4, and the connecting bolt 5 passes through the protective surface of the upper construction platform 1 and the sliding surface of the sliding plate 101 and is threadedly connected to the protective surface of the upper construction platform 1.
[0028] After the connecting bolt 5 is installed, its bolt head is attached to the sliding surface 2, and its threaded rod is connected to and fixed to the protective surface of the upper construction platform 1. By tightening the protective surface of the upper construction platform 1 and the sliding surface 2 of the sliding plate 101 with the connecting bolt 5, the distance between the two is controlled to prevent the upper construction platform 1 from flipping.
[0029] The lower end of the fixed surface of the upper construction platform 1 extends downward to the outer surface of the beam below the upper beam 4, further preventing the upper construction platform 1 from flipping inward toward the building.
[0030] One side of the upper construction platform 1 has a baffle 102, which is perpendicular to the upper construction platform 1 and formed by bending one side of the upper construction platform 1; the baffles 102 of the two sets of construction platform sets are arranged opposite to each other and parallel. The baffles 102 restrict the two sides of the stair slab to be installed after the stair slab is installed, so as to provide construction personnel with a reference for the installation position of the upper part of the stair slab during the stair installation, and facilitate the installation positioning of the construction personnel.
[0031] The upper end of the baffle 102 has a guide plate 103, which is pivotally connected to the upper end of the baffle 102; the guide plates 103 of the two sets of construction platform sets form a V-shaped guide groove. When the stair slab to be installed is hoisted and lowered from above, the upper tread of the stair slab to be installed first enters the guide groove, and when it deviates, it can fall along the inner wall of the guide groove, and finally fall between the two baffles 102.
[0032] The baffle 102 has several positioning bolts 104, which pass through the baffle 102 and are threadedly connected to it. When the upper tread of the stair slab to be installed needs to be finely adjusted, the positioning bolts 104 on the two baffles 102 can be used to push the two sides of the upper tread of the stair slab to be installed, making the adjustment operation relatively convenient.
[0033] One end of the sloping platform 3 is connected to the upper construction platform 1 and forms an obtuse angle with it. The sloping platform 3 has a rectangular frame 301 and a metal grid 302. The metal grid 302 is installed inside the rectangular frame 301 and welded to it. One end of the rectangular frame 301 is pivotally connected to the end of the upper construction platform 1. The rectangular frame 301 is formed by welding square steel pipes, has good strength, and can bear a large weight.
[0034] The sloping platform 3 has several parallel, spaced horizontal bars 303, the two ends of which are fixedly welded to the two sides of the rectangular frame 301. The horizontal bars 303 are made of materials such as steel pipes and can be used as footholds for climbing, facilitating the movement of construction workers.
[0035] The sloping platform 3 has a threaded support rod 6, which passes through the rectangular frame 301 of the sloping platform 3 and is threadedly connected to the rectangular frame 301.
[0036] The sloping platform 3 is located above the installed stair treads. When the length of the sloping platform 3 is sufficient, the end of the sloping platform 3 away from the upper construction platform 1 can rest on the steps of the installed stair treads below, providing good support. If the length of the sloping platform 3 is insufficient, threaded struts 6 can be used for support. As shown in the figure, when using threaded struts 6, the lower end of the threaded struts 6 is rotated and adjusted so that it rests on the steps of the installed stair treads below, thus providing support to the end of the sloping platform 3 away from the upper construction platform 1.
[0037] In another embodiment, the sloped platform 3 may have a central bending platform 304 constructed in the upper middle section, the central bending platform 304 being connected to a central step 305, and one end of the central step 305 being connected to the central bending platform 304 by bolts.
[0038] The width of the central step 305 should be less than half the width of the sloping platform 3, so as not to obstruct the climbing passage of the sloping platform 3. Furthermore, the central step 305 can be stepped on by personnel to facilitate the installation and positioning of the stair treads by construction workers from the side. The end of the central step 305 furthest from the sloping platform 3 can be designed as a hook to attach to an area of the building that has already been installed, such as a beam, thereby providing a certain degree of fixation and stability to the sloping platform 3.
[0039] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should be protected by the present invention.
