Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a device and construction method for increasing the load-bearing capacity of a scaffolding platform. Background Technology

[0002] With the increasing demands for functionality and aesthetics in buildings, the exterior design of buildings has incorporated many complex cantilevered slabs and lines, often poured simultaneously with the main structure. This poses numerous inconveniences for the construction of external scaffolding and elevator platform wall ties in high-rise buildings. Current technology often involves pre-embedding reinforcing bars or steel pipes within the walls as anchor points for wall ties, which are then cut during scaffold dismantling. When the pre-embedded reinforcing bars or steel pipes are insufficient, horizontal or vertical tie rods are also required at the openings.

[0003] Although pre-embedded steel bars or steel pipes or the addition of horizontal and vertical tie rods can ensure the anti-tilting capacity of the scaffolding, they cannot increase the platform load of the scaffolding. Furthermore, the pre-embedded method will waste pre-embedded materials and will also affect the construction and aesthetics of the building's exterior walls at the cutting points. Summary of the Invention

[0004] The purpose of this invention is to provide a device and construction method for increasing the load-bearing capacity of a scaffolding platform, in order to solve the problems mentioned above.

[0005] One technical solution adopted in this invention is: a device for increasing the load capacity of a scaffolding platform, comprising a horizontal connecting rod and a reinforcing tie rod. A force transmission base and an anchor bolt are movably connected to the horizontal connecting rod. Two adjacent sides of the force transmission base abut against the outer surface of the building. One end of the anchor bolt is connected to the building body, and the other end can move along the length of the horizontal connecting rod and is fixed by a locking device. The two ends of the reinforcing tie rod are respectively connected to the horizontal connecting rod and the scaffolding.

[0006] In some feasible implementations, the force transmission base includes a base body and a sleeve. The base body is in the shape of a right prism, wherein an installation groove is provided through it along the height direction. The sleeve is fixed in the installation groove, and the cross link passes through the sleeve.

[0007] In some feasible implementations, the base body includes adjacent sides that are perpendicular to each other, the adjacent sides respectively abutting against the vertical and horizontal surfaces of the building's outer surface.

[0008] In some feasible implementations, the base body is welded from a steel plate with a thickness of not less than 3 mm.

[0009] In some feasible implementations, one end of the anchor bolt is provided with a second sleeve, which is sleeved on the cross link. The locking member penetrates the wall of the second sleeve and abuts against the cross link.

[0010] In some feasible implementations, on the side near the second sleeve, the anchor bolt is provided with a plurality of reinforcing feet along the circumferential direction, and one end of the reinforcing feet is fixedly connected to the outer wall of the second sleeve.

[0011] In some feasible implementations, the reinforcing foot is plate-shaped, with its surface extending radially along the anchor bolt.

[0012] In some feasible implementations, the locking element is rod-shaped, with threads on its outer wall and a handle at the end extending out of the second sleeve.

[0013] In some feasible implementations, the reinforcing tie rod is connected to the cross link and / or the scaffold body by a cross-hinged connection.

[0014] Another technical solution adopted by the present invention is: a construction method using the device for increasing the load on the scaffolding platform as described above, the steps of which include:

[0015] Inspect the structural strength and integrity of the main building structure and reserved openings;

[0016] Clean the cantilever slabs on the exterior wall of the building, place the force transmission base on the cantilever slabs, and ensure that the adjacent two sides abut against the exterior wall of the building and the cantilever slabs respectively. Place the anchor bolts at the reserved openings and anchor them securely.

[0017] Pass the cross link through sleeve one and sleeve two, adjust the position appropriately, and then use the locking device to fix the cross link and sleeve two.

[0018] Based on the overall layout of the scaffolding, reinforced tie rods are installed on the scaffolding and connected and fixed to the horizontal connecting rods.

[0019] The beneficial effects of this invention are:

[0020] (1) By utilizing the reserved openings on the building, fully removable anchor bolts can be installed. They are easy to install and remove and will not damage the building surface. This improves the level of standardized construction and has good applicability and technical and economic benefits in engineering construction.

[0021] (2) By reinforcing tie rods, cross braces and force transmission bases, the gravity load on the scaffold is transferred to the building body, including its walls and cantilever slabs, which can effectively increase the platform load of the scaffold and ensure construction safety.

In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this invention through specific circumstances.

[0036] Reference Appendix Figure 1-3A device for increasing the load-bearing capacity of a scaffolding platform includes a horizontal connecting rod 10, a reinforcing tie rod 20, a force-transmitting base 30, and anchor bolts 40. The force-transmitting base 30 includes a base body 31 and a first sleeve 32. Two adjacent sides of the base body 31 abut against the outer surface of the building. The base body 31 is a right prism shape, with a mounting groove 31-1 extending along the height line. The first sleeve 32 is fixed in the mounting groove 31-1, and the horizontal connecting rod 10 passes through the first sleeve 32. One end of the anchor bolt 40 is connected to the building body, and the other end is fixed to a second sleeve 50. The horizontal connecting rod 10 passes through the second sleeve 50. The second sleeve 50 is provided with a locking element 60 that can fix the positions of the horizontal connecting rod 10 and the second sleeve 50, allowing the anchor bolt 40 to move along the length of the horizontal connecting rod 10 and be fixed by the locking element 60. The two ends of the reinforcing tie rod 20 are respectively connected to the horizontal connecting rod 10 and the scaffolding 80.

[0037] The aforementioned horizontal connecting rods 10 are continuous, integrally formed rods to ensure the structural stability and force transmission stability of the erected scaffolding 80. The number of reinforcing railings, force transmission bases 30, and anchor bolts 40 can be configured according to actual usage requirements, and no specific limitation is made here.

[0038] When using this device to erect scaffolding 80, first install force transmission bases 30 and anchor bolts 40 on the exterior wall of the building. The specific method is as follows: place the force transmission base 30 on the exterior wall of the building with a protruding cantilever plate, such as an air conditioning panel, with the two adjacent sides of the base body 31 abutting against the exterior wall surface and the top surface of the air conditioning panel, respectively; fix the end of the anchor bolt 40 away from the sleeve 2 through the reserved opening on the building body, and at the same time adjust each sleeve 1 32 and sleeve 2 50 to be in a coaxial state; pass the horizontal connecting rod 10 through the sleeve 1 32 and sleeve 2 50, adjust the position appropriately, and use the locking piece 60 to connect and fix the sleeve 2 50 and the horizontal connecting rod 10; finally, according to the overall layout of the scaffolding 80, install reinforcing tie rods 20 on the scaffolding 80 and connect and fix them to the horizontal connecting rods 10.

[0039] The reinforcing tie rod 20 directly connects the scaffold 80 body and the horizontal connecting rod 10, which can transfer the gravity load borne by the scaffold 80 during construction to the horizontal connecting rod 10, and then transfer it to the building body through the force transmission base 30. This can effectively improve the platform load of the scaffold 80. At the same time, all components in this device can be easily and completely detached from the building body after construction. The operation is simple and will not cause material waste. The construction process is green and environmentally friendly.

[0040] The shape of the base body 31 can be configured according to actual usage requirements, such as being made into a triangular prism, a quadrangular prism, etc., and no specific limitation is made in this invention. However, since the external wall cantilever structure of most civil buildings is regular, such as air conditioning panels, this embodiment provides some implementation methods with larger actual usage requirements: the base body 31 includes adjacent sides that are perpendicular to each other, and these two adjacent sides respectively abut against the vertical and horizontal surfaces of the building's outer surface.

[0041] The aforementioned base body 31 can be formed by welding steel plates with a thickness of not less than 3mm. Its interior can be hollow or solid. The steel plate can be welded inside its outer shell to increase the stability of the overall structure. The mounting groove 31-1 is configured as a U-shaped groove, and the outer wall of the sleeve 32 is welded and fixed to the three inner walls of the U-shaped groove to increase the stability of the overall structure.

[0042] To further increase the stability of the overall structure, in this embodiment, a plurality of reinforcing feet 70 are provided circumferentially on the anchor bolt 40 on the side near the second sleeve 50, and one end of the reinforcing feet 70 is welded and fixed to the outer wall of the second sleeve 50.

[0043] The number and shape of the reinforcing feet 70 can be configured according to actual usage requirements. For example, they can be plate-shaped or other three-dimensional structures that extend along the anchor bolts 40. For example, two, three, four, five or more can be evenly arranged along the circumference of the anchor bolts 40. No specific limitation is made here.

[0044] In this embodiment, the locking member 60 is configured as a rod with threads on its outer wall and a handle at the end extending from the second sleeve 50 for easy operation by the worker. After the end of the locking member 60 away from the handle penetrates the wall of the second sleeve 50, it abuts against the cross link 10. By rotating the locking member 60 in different directions, the second sleeve and the cross link 10 can be loosened or fixed.

[0045] Reference Appendix Figure 1 The reinforcing tie rod 20 is connected to the horizontal connecting rod 10 and the scaffold body 80 by a cross-hinged connection. The reinforcing tie rod 20 may include diagonal tie rods and vertical tie rods, and the number and position of both can be configured according to actual usage requirements, without specific limitations here. Preferably, when the diagonal tie rods, vertical tie rods and the plane of the scaffold 80 form a triangular stable structure, the planar load of the scaffold 80 can be greatly improved.

[0046] The construction method of this device includes the following steps:

[0047] Check whether the main structure of the building meets the strength requirements and whether there are cracks or voids in the reserved openings that may affect the strength;

[0048] Clean the cantilevered slabs on the exterior wall of the building, and install a force transmission base 30 every 400mm to 600mm. Place the anchor bolts 40 at the reserved opening and anchor them stably, while ensuring that sleeve 1 32 and sleeve 2 50 are in a coaxial state.

[0049] Pass the cross link 10 through the first sleeve 32 and the second sleeve 50, adjust its position appropriately, and then use the locking piece 60 to fix the cross link 10 and the second sleeve 50.

[0050] Based on the overall layout of the scaffold 80, reinforcing tie rods 20 are installed on the scaffold 80 and connected and fixed to the horizontal connecting rods 10.

[0051] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0052] (1) By utilizing the reserved openings on the building, fully removable anchor bolts 40 are arranged. They are easy to install and remove and will not damage the building surface. This improves the level of standardized construction and has good applicability and technical and economic benefits in engineering construction.

[0053] (2) By reinforcing the tie rod 20, the horizontal connecting rod 10 and the force transmission base 30, the gravity load on the scaffold 80 is transferred to the building body, including its walls and cantilever slabs, which can effectively increase the platform load of the scaffold 80 and ensure construction safety.

[0054] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
