Description

Technical Field

[0001] The present application relates to the technical field of cantilever scaffolds for construction, and in particular to a cantilever scaffold for stone laying construction of building exterior walls. Background Art

[0002] The purpose of stone paving on the exterior walls of buildings is to improve the aesthetics, durability, thermal insulation, safety and convenience of cleaning and maintenance of the building. When paving stone on the exterior walls of buildings, it is generally necessary to build scaffolding first. Among them, cantilever scaffolding plays an important role in high-rise building construction with its advantages of high efficiency and safety, flexibility, cost savings, convenient construction, technological innovation, environmental friendliness and improved construction efficiency. Cantilever scaffolding uses a cantilever structure extending outward from the edge of the building structure to support the external scaffolding, and transfers all or part of the scaffolding load to the building structure.

[0003] However, the existing cantilever scaffolding mainly includes two types. One is a rod body used for support fixed by bolts and nuts, such as the invention patent with application number 2024112302631, and the patent name is a flower basket type cantilever scaffolding structure. Its horizontal bars and vertical bars are fixed by bolts and nuts. When dismantling, the staff needs to first remove the multiple bolts fixing the cantilever scaffolding and then dismantle the erected cantilever scaffolding. The operation is relatively complicated, which makes the labor intensity of the staff higher and is inconvenient to install and dismantle.

[0004] The other is the socket-and-spigot type steel pipe scaffolding, such as the application number 2020228182586, and the patent name is a utility model patent for a socket-and-spigot type steel pipe scaffold. The joint at one end of the horizontal rod is plugged into the connecting plate through a pin to fix the horizontal rod. Because the joints at both ends of the horizontal rod are respectively fixed to the two connecting plates, this requires precise setting of the relationship between the length of the horizontal rod and the spacing value of the two connecting plates, and thus has high requirements for setting the spacing value of the I-beam. It is more troublesome in actual use, and the loosening of the pin can easily affect the stability of the connection structure between the connector and the connecting plate. Summary of the Invention

[0005] The present application proposes a cantilever scaffold for stone laying construction on building exterior walls, which has the advantages of being easy to install and disassemble and having a low requirement for the spacing value of I-beams. It is used to solve the problem that existing cantilever scaffolds are inconvenient to install and disassemble when fixed with bolts and nuts, and to solve the problem that existing socket-type steel pipe scaffolds have precise requirements for the spacing of I-beams, the spacing of two connecting plates, and the length of horizontal rods, as well as the hidden dangers of stability.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a cantilever scaffold for stone laying construction of building exterior walls, comprising a vertical pole fixedly mounted on an I-beam, wherein at least one socket plate is provided on the vertical pole, and at least two rod body fixing assemblies are installed on each of the socket plates, wherein the rod body fixing assembly comprises a U-shaped sleeve, and a positioning block is movably provided at one end of the inner side of the U-shaped sleeve, and a plug plate is plugged into the middle of the connection part of the U-shaped sleeve and the positioning block, and the bottom end of the plug plate passes through the slot and extends to the bottom of the socket plate, and a slot is provided on the plug plate away from one side of the vertical pole, and the inner top of the slot is exactly in the same plane as the bottom of the socket plate, and a limiting ring is provided below the socket plate, and a notch is reserved for the plug plate to pass through. A cross bar is movably socketed on the end of the U-shaped sleeve away from the positioning block.

[0007] Furthermore, the socket plate is fixed to the vertical pole by welding, ensuring that the socket plate and the vertical pole remain in a stable and fixed state, thereby ensuring the stability of the cantilever scaffolding.

[0008] Furthermore, a limiting block is fixedly installed on the side of the positioning block away from the vertical pole, and the side of the limiting block away from the positioning block is adapted to the outer curvature of the cross bar. The cross bar is clamped by the limiting block and the positioning block, thereby ensuring the stability of the rod body used to support the cantilever scaffolding.

[0009] Furthermore, one end of the limiting ring is provided with a protrusion facing outward, and the end of the limiting ring away from the protrusion is designed with a bevel, which makes it convenient for one end of the limiting ring to pass through the slot on the plug plate by rotating, thereby fixing the plug plate, ensuring the stability of the connection structure between the cross bar and the U-shaped sleeve.

[0010] Furthermore, the socket disc is provided with four sockets, which are distributed in a circular array on the socket disc, and the four sockets are staggered with the four slots. The limiting ring is provided with four through holes that are compatible with the sockets, and the four through holes are distributed in a circular array on the limiting ring. A pin is movably inserted in the socket, and the bottom end of the pin extends to the bottom of the through hole. After the plug plate is positioned by the limiting ring, the pin is used to limit the limiting ring to prevent the limiting ring from rotating.

[0011] Furthermore, the central angle of the notch on the limiting ring is 20°-60°, and the inserting plate can be inserted into the notch of the limiting ring, so that after the limiting ring is rotated, the limiting ring is clamped in the slot on the inserting plate.

[0012] Furthermore, the bottom end of the plug board is designed with an inclined surface, which facilitates the plug board to be smoothly inserted into the U-shaped sleeve, the positioning block and the slot to fix the rod body fixing assembly.

[0013] The locking mechanism is configured to lock the locking cam of the locking cam, and the locking cam is configured to lock the locking cam of the locking cam, wherein the locking cam is secured to the locking cam of the locking cam.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present application provides a cantilever scaffold for stone laying construction on building exterior walls. The crossbar is covered with a U-shaped sleeve and a plug plate is inserted into a socket plate for positioning. Compared with the existing scaffolding fixed with bolts and nuts, it is convenient for installation and disassembly.

[0016] 2. The present application provides a cantilever scaffold for stone laying construction on building exterior walls. Compared with the existing socket-and-spigot type steel pipe scaffold, the positioning of the plug plates is carried out by limiting rings, which makes the scaffold more stable. In addition, compared with the existing socket-and-spigot type steel pipe scaffold, each two socket plates can only directly fix one short cross bar. A longer cross bar can be fixed by the rod fixing assembly on multiple socket plates, so that the spacing accuracy requirements of the I-beams installed on the floor slab are lower, and there is no need to ensure that the spacing of the socket plates on the two I-beams is accurately adapted to the length of the cross bar, which is more convenient for actual use and has the advantage of high applicability. In addition, by limiting the plug plates by limiting rings, the mechanical structure of the plug plates is stable and not easy to loosen, which further improves the stability of the cantilever scaffold.

[0017] 3. The present application provides a cantilever scaffold for stone laying construction on building exterior walls. The four support grooves on the positioning sleeve are aligned with four support bars respectively, and the support bars are used to support the positioning sleeve, thereby stably supporting the socket plate and the rod fixing assembly as a whole. Compared with the first embodiment, there is no need to weld the socket plate to the vertical pole, which makes it more convenient to transport the vertical pole and the socket plate separately and saves welding time.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] Example 1, as Figure 1A cantilever scaffold for laying stone on the exterior wall of a building includes several I-beams 100 installed on a floor slab (not shown in the figure), and the several I-beams 100 are arranged equidistantly on the floor slab. A group of vertical poles 200 are fixedly installed on the part of each I-beam 100 extending outside the floor slab. The number of vertical poles 200 in a group is two, one of which is close to the floor slab and the other is away from the floor slab. Each vertical pole 200 is provided with at least one socket plate 300, and each socket plate 300 is installed with at least two rod fixing assemblies 400. The socket plate 300 can be fixed to the vertical pole 200 by welding.

[0029] See also Figure 1-Figure 3 , a slot 301 is provided on the socket disk 300, and the number of the slots 301 is four, and the four slots 301 are distributed in a circular array on the socket disk 300, the rod fixing assembly 400 includes a U-shaped sleeve 401, and a positioning block 402 is movably provided at one end of the inner side of the U-shaped sleeve 401, and a plug-in plate 403 is plugged into the middle of the connection part between the U-shaped sleeve 401 and the positioning block 402, and the bottom end of the plug-in plate 403 passes through the slot 301 and extends to the bottom of the socket disk 300, and a card slot 4031 is provided on the plug-in plate 403 away from the side of the vertical rod 200, and the card slot 403 The inner top of 1 is just located on the same plane as the bottom of the socket disk 300. A limiting ring 500 is provided below the socket disk 300. The limiting ring 500 has a gap reserved for the insertion plate 403 to pass through, and one end of the limiting ring 500 is provided with a protrusion facing outward, so that the limiting ring 500 can be rotated by the protrusion structure. When the insertion plate 403 is inserted into the slot 301, the insertion plate 403 is located at the gap of the limiting ring 500. Then, by rotating the limiting ring 500, the limiting ring 500 passes through the card slot 4031, thereby fixing the insertion plate 403. Figure 5 Status shown.

[0030] The U-shaped sleeve 401 has a crossbar 600 at one end thereof away from the positioning block 402. The crossbar 600 provided on the vertical pole 200 is used as a support pole of the scaffold. Figure 1In the state shown, the U-shaped sleeve 401 is used to cover the cross bar 600, and the plug plate 403 is inserted into the socket plate 300 for positioning. Compared with the existing scaffolding that uses bolts and nuts for fixing, it is convenient for installation and disassembly. Compared with the existing socket-type steel pipe scaffolding, the plug plate 403 is positioned by the limiting ring 500, which makes the scaffolding more stable. Compared with the existing socket-type steel pipe scaffolding, only one short cross bar 600 can be directly fixed for every two socket plates 300. In this application, it is not limited to directly fixing one cross bar 600 on two socket plates 300, that is, the rod fixing assembly 400 on multiple socket plates 300 can fix a longer cross bar 600. The spacing accuracy requirements of the I-beam 100 installed on the floor slab are relatively low, and there is no need to ensure that the spacing of the socket plates 300 on the two I-beams 100 is accurately adapted to the length of the cross bar 600, which is more convenient for actual use and has the advantage of high applicability.

[0031] A limiting block 404 is fixedly installed on the side of the positioning block 402 away from the vertical pole 200, and the side of the limiting block 404 away from the positioning block 402 is adapted to the outer curvature of the cross bar 600. The limiting block 404 cooperates with the inner wall of the U-shaped sleeve 401 to clamp and limit the cross bar 600, ensuring that the cross bar 600 is in a stable state after installation.

[0032] The central angle of the notch on the limiting ring 500 is 20°-60°, ensuring that the plug plate 403 can be inserted into the notch of the limiting ring 500. After the limiting ring 500 is rotated, the limiting ring 500 is clamped in the slot 4031 on the plug plate 403, thereby fixing the plug plate 403, ensuring the stability of the overall structure of the rod fixing assembly 400 and the cross bar 600, and thus ensuring the overall stability of the cantilever scaffolding.

[0033] The socket disc 300 is provided with four sockets 302, which are distributed in a circular array on the socket disc 300, and the four sockets 302 are staggered with the four slots 301. The limiting ring 500 is provided with four through holes 501 that are compatible with the sockets 302, and the four through holes 501 are distributed in a circular array on the limiting ring 500. A pin 700 is movably inserted into the socket 302, and the bottom end of the pin 700 extends to the bottom of the through hole 501. After the insert plate 403 is positioned by the limiting ring 500, the pin 700 is used to limit the limiting ring 500 to prevent the limiting ring 500 from rotating, causing the insert plate 403 to be located at the notch of the limiting ring 500, affecting the stability of the insert plate 403.

[0034] See also Figure 3-Figure 4The end of the limiting ring 500 away from the protrusion is designed with a bevel, which makes it convenient for one end of the limiting ring 500 to pass through the slot 4031 when the limiting ring 500 rotates. The bottom end of the slot 4031 is designed with a bevel, which makes it convenient for the plug-in plate 403 to pass through the U-shaped sleeve 401, the positioning block 402 and the slot 301, thereby facilitating the installation and disassembly of the cantilever scaffolding.
