Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, especially an integrated angle brace cantilever scaffold. BACKGROUND

[0002] The cantilever scaffold on the outer wall is a working platform erected to ensure the smooth progress of each construction process, and generally adopts a multi-layer cantilever mode (one cantilever per 5-6 layers). At present, most of the traditional cantilever scaffolds of outer walls are fixed on the outer walls by I-beams, and in the process of erecting the cantilever scaffold, diagonal bracing members and support assemblies are usually used to reinforce the cantilever scaffold to ensure its stability.

[0003] It is common knowledge in the field to set a lower angle brace: set a diagonal brace or use another group of I-beams as reinforcement. For example, the published invention patent "Novel bolted adjustable square steel pipe cantilever scaffold and construction method" (application publication number CN116623926A) mentions that a square steel pipe is used as a cantilever bearing structure, and one end of the square steel pipe is fixedly connected to the outer wall of the building through a first high-strength fixing bolt during use, and the lower side is supported by a connection with a round steel pipe diagonal brace, thereby forming a triangular structure to effectively support the cantilever square steel pipe.

[0004] However, in the current construction process, the height and position of the reserved hole are not accurate, which requires the construction personnel to constantly adjust the length of the diagonal brace during construction, making the operation steps of the cantilever scaffold very cumbersome. The parallel I-beam scheme has unclear force transmission and requires more materials, and cannot solve the safety hazard problem caused by the incorrect cantilever I-beam structure. SUMMARY

[0005] The utility model aims at the deficiency of the prior art, and provides an integrated angle brace cantilever scaffold, which is formed by fixing the cantilever beam, angle steel and back plate on the ground to form a combination, and then quickly connecting the combination with the embedded part embedded in the main body of the building, thereby solving the problems of inconvenient installation of diagonal brace and complicated operation steps of the existing cantilever scaffold, and further solving the problems of the diagonal brace affecting the walking of construction personnel and reinforcing the existing defective cantilever I-beam.

[0006] The utility model is achieved by the following technical solutions:

[0007] An integrated angle support cantilever scaffold is characterized in that: comprising a cantilever beam, an angle support, a back plate and a pre-embedded part, wherein the angle support is arranged below the cantilever beam to form a combined structure, the back plate is arranged on one side of the cantilever beam and the angle support and is further welded to form an integral structure, the pre-embedded part is embedded in the inside of a building body, and the back plate and the pre-embedded part are fixedly connected through a connecting screw rod.

[0008] The pre-embedded part comprises a tension plate and the internally-threaded sleeve, one side of the internally-threaded sleeve is directed towards the back plate, the other side of the internally-threaded sleeve is fixedly connected with the tension plate to form an integral structure, and the internally-threaded sleeve is matched with the connecting screw rod.

[0009] The back plate is provided with long circular holes matched with the connecting screw rod.

[0010] The number of the long circular holes is two, and the two long circular holes are arranged perpendicularly.

[0011] The cantilever beam is provided with a positioning pin matched with the width of an outer scaffold.

[0012] The cantilever beam and the angle support are arranged perpendicularly.

[0013] The advantages of the utility model are: the cantilever beam structure is welded to be an integral whole on the ground, the air operation process and time are reduced, the safety risk and construction difficulty are reduced, the construction is simple, the pre-embedded threaded sleeve scheme is proposed, the customized high-strength screw rod is adopted for connection, there is no through hole on the external structure in the construction process, the leakage risk is effectively reduced, meanwhile, the steel member angle support is arranged vertically at the lower part, the height of the angle support steel member is greater than the distance between the inner vertical rod of the scaffold and the external structure, so that the end deformation of the cantilever I-beam is effectively reduced, the maximum stress is less than the yield strength of the cantilever I-beam through calculation, the cantilever I-beam material performance is more fully utilized and material is saved, meanwhile, the I-beam can be placed vertically, the bending moment and pressure that can be borne by the I-beam top surface and wall surface butt joint are supplemented, so that the defective cantilever I-beam is reinforced.

[0018] The features and other related features of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate the understanding of those skilled in the art:

[0019] like Figures 1-4 As shown in the figure, the markings 1-10 represent: 1. Main building structure, 2. Cantilever beam, 3. I-beam corner brace, 4. Back plate, 5. Positioning pin, 6. Connecting bolt, 7. Weld, 8. Connecting hole, 9. Tension plate, 10. Internal threaded sleeve.

[0020] Example: Figures 1 to 4 As shown, the integrated cantilever scaffolding in this embodiment mainly includes a cantilever beam 2, a corner brace 3, and embedded parts. The embedded parts are pre-installed within the main building 1 and correspond to the exterior facade of the scaffolding. The corner brace 3 is located below the cantilever beam 2, and the two are welded together to form a composite structure. The corner brace 3 is placed perpendicular to the cantilever beam 2, with one end face flush with it. A back plate 4 is installed at this end face, and the back plate 4 is also welded to and fixed to the composite structure formed by the cantilever beam 2 and the angle steel 3 to form an integral structure. The composite structure and the main building 1 are connected together by threaded connecting bolts 6 at both ends and the embedded parts, forming a stable support structure that provides stable support for the external scaffolding.

[0021] Combination Figure 1 and Figure 3 As shown, a back plate 4 is provided at one end of the cantilever beam 2. The back plate 4 has two elongated holes 8, and the length directions of the two elongated holes 8 are perpendicular to each other, so that fine adjustment can be achieved in four directions (up, down, left, and right) when the back plate 4 is installed.

[0022] Two positioning pins 5 are installed on the upper part of the two selected 2s for installation with the scaffold uprights. The positioning pins 5 are made of steel bars with a diameter of 25mm. The inner positioning pin is located within the width range of the corner brace 3. The spacing between the two positioning pins 5 is determined according to the width of the outer scaffold.

[0023] The corner brace 3 is cut from steel components with a flat cut surface. Its specific specifications can be No. 30 I-beams or structural steel. The optimal length is calculated to be 150mm. The cantilever beam 2 and the corner brace 3 are both welded with an 8mm bevel. The weld 7 forming the L-angle area should be chamfered.

[0024] Combination Figure 1 and Figure 3 As shown, the embedded parts in the main building 1 include a tension plate 9 and an internal threaded sleeve 10, which are welded together to form a whole. Before the concrete is poured, the tension plate 9 is simultaneously welded to the transverse and longitudinal steel bars on the inner side of the main building 1. The overall length of the embedded parts is less than the wall thickness, and no through bolt holes are formed, which greatly reduces the risk of leakage on the external structure.

[0025] The embodiment is constructed, and the specific operation steps are as follows:

[0026] Before the concrete pouring of the building body 1, the installation position of the cantilever beam 2 is determined in advance, the embedded part is welded with the inner steel bars of the building body 1, the gusset 3, the cantilever beam 2, the back plate 4, the positioning pin 5 and the like are welded on the ground before construction and installation, after the concrete of the building body 1 reaches the required strength according to the specification, the connecting screw rod 6 is connected with the inner threaded sleeve 10, then the welded combination is hoisted to the corresponding position, the position can be slightly adjusted in the plane through the long round holes 8 on the back plate 4, and the integrated gusset cantilever scaffold is quickly and accurately installed.

[0027] Although the above embodiment has been described in detail with reference to the drawings for the purpose of the concept and embodiment of the utility model, those skilled in the art can realize that various improvements and changes can be made to the utility model without departing from the scope defined by the claims, and therefore, detailed description is not given here.
