Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building construction, in particular to a cantilever scaffold. Background Art
[0002] Traditional scaffolding construction methods are often limited by height, space and safety, and cannot meet the requirements of modern buildings. Therefore, the emergence of cantilever scaffolding fills this gap. Cantilever scaffolding is a cantilever structure. Its basic principle is to support the scaffolding platform through a support frame suspended on the outside of the building. It usually consists of a main beam, a support system, a cantilever arm and a working platform. In addition to the above components, cantilever scaffolding usually uses wall ties, which connect the scaffolding body to the building wall at a certain height distance, which plays a role in enhancing the stability of the scaffolding and preventing the scaffolding from becoming unstable due to excessive height.
[0003] However, the wall connection itself cannot bear the load of the scaffolding and only plays an auxiliary role in maintaining stability. Since the load-bearing capacity and stability of the cantilever scaffolding are lower than those of ordinary ground-based scaffolding, when the cantilever scaffolding collapses, the scaffolding lacks an effective auxiliary support structure. Too few insurance measures cause the scaffolding to collapse too quickly, ultimately preventing the internal personnel from reacting in time to escape. Utility Model Content
[0004] The purpose of the utility model is to provide a cantilever scaffold to solve the problems raised in the above-mentioned prior art.
[0005] A cantilever scaffold is provided, comprising:
[0006] A main structure, a cantilevered steel beam and a frame erected on the cantilevered steel beam, wherein the cantilevered steel beam is fixedly connected to the main structure, the frame has at least two reinforcing trusses in both the height direction and the width direction, the reinforcing trusses are connected to the internal frame of the frame, a tie rod is provided between the reinforcing truss and the main structure at the corresponding floor height, and both ends of the tie rod are respectively hinged to the reinforcing truss and the main structure.
[0007] Furthermore, an anchor rod is anchored inside the main structure, and a hinge support is provided at one end of the anchor rod located outside the main structure, and the hinge support is hinged to the pull rod.
[0008] Furthermore, the frame includes vertical poles, horizontal braces and diagonal braces that are interconnected, and the vertical poles, horizontal braces and diagonal braces at least form a triangular frame structure, and the reinforcing truss is arranged inside the triangular frame structure.
[0009] Furthermore, a plurality of reinforcement nodes are formed at the connection parts between the reinforcement truss and the triangular frame structure, and one end of the pull rod away from the main structure is hinged to at least one reinforcement node.
[0010] Furthermore, the pull rod is hinged to a reinforcement node formed between the reinforcement truss and the diagonal bracing rod.
[0011] Furthermore, the vertical poles and the horizontal bracing poles form a rectangular frame, and the triangular frame structure is formed on the inner corner of the top of the rectangular frame on one side close to the main structure.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The tie rod connects the main structure to the frame through two hinged ends, which not only improves the overall stability of the frame, but also provides additional support when the frame collapses, so that the frame forms a hanging basket structure under the support of at least four tie rods, which can prevent the main structure from falling or delay the falling time, providing sufficient time for personnel to escape. Strengthening the truss can improve the strength of the connection between the tie rod and the frame, and avoid local structural instability at the connection between the tie rod and the frame.

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0019] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-2 As shown, in an embodiment of the utility model, a cantilever scaffolding includes a main structure 1, a cantilever steel beam 2 and a frame body 3 erected on the cantilever steel beam 2, the cantilever steel beam 2 and the main structure 1 are fixedly connected, the frame body 3 has at least two reinforcing trusses 4 in the height direction and the width direction, the reinforcing trusses 4 are connected to the internal frame of the frame body 3, and a pull rod 5 is arranged between the reinforcing truss 4 and the main structure 1 at the corresponding floor height, and the two ends of the pull rod 5 are respectively hinged to the reinforcing truss 4 and the main structure 1.
[0021] The cantilever steel beam 2 is fixed to the main structure 1 by anchors, and the frame 3 is erected on the cantilever steel beam 2 to form a cantilever structure outside the main structure 1. The main structure 1 is divided into a floor, a beam and a column, and one end of the tie rod 5 can be hinged on the floor, the beam or the column. The frame 3 forms a number of rectangular frames in the height direction as a manhole, and diagonal braces 33 are arranged on both sides of the width direction of the frame 3 to reinforce the overall structure. Since the length of each rod forming the frame 3 is relatively long, the force on the middle part of the rod is likely to cause the rod to become unstable. Therefore, the role of the reinforcing truss 4 is to enhance the local structural strength of the rectangular frame, so that when the frame 3 transmits the force to the tie rod 5, the overall structure will not be destroyed due to the instability of the local structure.
[0022] The frame 3 has at least two reinforcing trusses 4 in both the height direction and the width direction. At least two supporting points in the height direction and the width direction prevent the main structure 1 from tipping over as a whole due to unstable center of gravity.
[0023] The main structure 1 includes a floor, a beam and a column. It is preferred to anchor the anchor rod 6 inside the beam or column to avoid setting the anchor rod 6 inside the floor to prevent water seepage caused by insufficient repair of the floor and to prevent the tie rod 5 from interfering with the beam due to the need to be riveted to the floor. The hinge support 7 is fixed to the outside of the main structure 1 through the anchor rod 6 and is used to be hinged with the tie rod 5.
[0024] The rectangular frame structure of the frame body 3 in the lateral direction is formed by vertical poles 31 and horizontal braces 32. Multiple frame structures are arranged and connected in sequence in the width direction to form several manholes in the height direction. The rectangular frames on both sides of the frame body 3 in the width direction are reinforced by diagonal braces 33. If the construction conditions are met, some diagonal braces 33 can also be appropriately set in the middle of the path of the manhole in the length direction for reinforcement. The vertical poles 31, the horizontal braces 32 and the diagonal braces 33 can be connected by fasteners to form a triangular frame structure to improve stability. The reinforcing truss 4 is set inside the triangular frame structure to improve the local stability here, as the force-bearing part that bears the force of the pull rod 5.
[0025] Several reinforcement nodes 8 are formed at the connection parts of the reinforcement truss 4 and the triangular frame structure, and the length of each rod on the triangular frame structure is shortened by the reinforcement nodes 8, thereby reducing the probability of structural instability. The end of the pull rod 5 away from the main structure 1 is hinged to at least one reinforcement node 8, so as to avoid some rods on the reinforcement truss 4 directly bearing the force, and instead, the force is converted into the internal force of each rod of the reinforcement truss 4 through the reinforcement node 8, so that the force is evenly distributed.
[0026] Furthermore, the pull rod 5 is hinged to the reinforcement node 8 formed between the reinforcement truss 4 and the diagonal brace rod 33, so that the force form is more reasonable.
[0027] The vertical poles 31 and the horizontal braces 32 form a rectangular frame, and the triangular frame structure is formed at the inner corner of the top of the rectangular frame near the main structure 1. This structural arrangement can avoid the working range as much as possible and minimize the space occupied inside the passage.
[0028] The above contents are merely examples and explanations of the structure of the utility model. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
