Description

Technical Field

[0001] This utility model relates to the field of cantilever scaffolding, specifically a new type of cantilever scaffolding. Background Technology

[0002] Cantilever scaffolding is a construction support system that transfers scaffolding loads to the exterior walls of a building through a cantilevered load-bearing structure. Its core feature is that it does not rely on a ground foundation, but rather cantilevered outwards from the middle floors of the building. It is suitable for high-rise buildings, irregularly shaped structures, or projects with limited space.

[0003] When constructing on the exterior of high-rise buildings, cantilevered scaffolding is required. However, the boards that cantilevered scaffolding typically provides for workers to step on are bamboo mats, also known as bamboo scaffold boards. Since construction usually takes a long time, bamboo scaffold boards may become brittle and break after long-term use, potentially causing construction safety hazards. Utility Model Content

[0004] To overcome the shortcomings of existing technology, the planks provided for workers to step on in conventional cantilever scaffolding are bamboo strips, also known as bamboo scaffolding boards. Since construction is generally a long process, bamboo scaffolding boards may become brittle and break after long-term use, which may cause construction safety hazards. This utility model proposes a new type of cantilever scaffolding.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a novel cantilever scaffold, including a cantilever scaffold body, the cantilever scaffold body including I-beams, the number of I-beams being three, one side of the I-beams being provided with a building exterior wall, the surface of the I-beams being fixedly connected to the surface of the building exterior wall by bolts, the top of each I-beam being fixedly connected with a vertical bar, the surface of the vertical bar being fixedly connected with a horizontal bar by a connector, the surface of the horizontal bar being fixedly connected with a support rod by a connector, and the surface of the support rod being provided with a support mechanism;

[0006] The support mechanism includes a support plate located at the top of the support rod. An extension plate is movably connected to the inner cavity of the support plate. There are two extension plates, and two sliding blocks are fixedly connected to the surface of each extension plate. The surface of the sliding blocks is movably connected to the inner cavity of the support plate.

[0007] Preferably, the inner cavity of the support plate is provided with a sliding groove, and the number of sliding grooves is two, and the inner cavity of the sliding groove is movably connected to the surface of the sliding block.

[0008] Preferably, the inner cavity of the sliding groove is fixedly connected with a stop block, and the surface of each stop block is in contact with the surface of the sliding block.

[0009] Preferably, each of the extension plates has two bidirectional threaded rods movably connected to its inner cavity. One end of each bidirectional threaded rod is fixedly connected to a rotating block. Each bidirectional threaded rod has a dovetail block threadedly connected to its surface. The surface of the dovetail block is movably connected to the inner cavity of the extension plate. A clamping block is fixedly connected to the bottom of the dovetail block. The inner cavity of the clamping block is in contact with the surface of the support rod.

[0010] Preferably, each of the extension plates has a dovetail groove at its bottom, and the inner cavity of the dovetail groove is movably connected to the surface of the dovetail block.

[0011] Preferably, the surface of the bidirectional threaded rod is fixedly connected with a sliding groove, and the outer ring of the sliding groove is fixedly connected to the inner cavity of the dovetail groove.

[0012] Preferably, a damping pad is fixedly connected to the inner side of the clamping block. The damping pad is made of rubber, and the surface of the damping pad is in contact with the surface of the extension plate.

[0013] The advantages of this utility model are:

[0014] This utility model utilizes a combination of building exterior walls, cantilevered scaffold body, and support mechanism. After the cantilevered scaffold body is installed on the building exterior wall, the support mechanism is unfolded and fixed to the surface of the support rod, achieving a support effect for workers walking on the surface of the support rod. The material of this support structure is more robust and durable than bamboo scaffold boards, solving the problem that the boards provided for workers to step on in ordinary cantilevered scaffolds are bamboo mats, also known as bamboo scaffold boards. Due to the generally long construction time, bamboo scaffold boards may become fragile and break after long-term use, potentially causing construction safety hazards. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a novel cantilever scaffolding. (Refer to...) Figure 1 and Figure 4 A novel cantilever scaffolding includes a cantilever scaffolding body 2, which includes three I-beams 204. A building exterior wall 1 is provided on one side of each I-beam 204. The surface of the I-beam 204 is fixedly connected to the surface of the building exterior wall 1 by bolts. A vertical bar 201 is fixedly connected to the top of each I-beam 204. A horizontal bar 203 is fixedly connected to the surface of the vertical bar 201 by connectors. A support bar 202 is fixedly connected to the surface of the horizontal bar 203 by connectors. A support mechanism 3 is provided on the surface of the support bar 202.

[0024] The support mechanism 3 includes a support plate 301, which is located at the top of the support rod 202. An extension plate 302 is movably connected to the inner cavity of the support plate 301. There are two extension plates 302, and two sliding blocks 303 are fixedly connected to the surface of each extension plate 302. The surface of the sliding blocks 303 is movably connected to the inner cavity of the support plate 301.

[0025] Reference Figure 3 The inner cavity of the support plate 301 is provided with two sliding grooves 304. The inner cavity of the sliding groove 304 is movably connected to the surface of the sliding block 303. The sliding groove 304 guides the sliding block 303 to slide in the inner cavity of the support plate 301, and indirectly guides the extension plate 302 to slide in the inner cavity of the support plate 301, thereby improving the stability of the extension plate 302 sliding in the inner cavity of the support plate 301.

[0026] Reference Figure 3 The inner cavity of the sliding groove 304 is fixedly connected with a stop block 311. The surface of each stop block 311 is in contact with the surface of the sliding block 303. The stop block 311 is set to limit the sliding block 303 in the inner cavity of the sliding groove 304. When the extension plate 302 drives the sliding block 303 to slide in the inner cavity of the sliding groove 304 and contact the surface of the stop block 311, the sliding block 303 slides outward to the maximum extent in the inner cavity of the sliding groove 304, preventing the sliding block 303 from sliding out of the inner cavity of the sliding groove 304, and indirectly preventing the extension plate 302 from detaching from the inner cavity of the support plate 301.

[0027] Reference Figure 4 Each extension plate 302 has two bidirectional threaded rods 306 movably connected to its inner cavity. One end of each bidirectional threaded rod 306 is fixedly connected to a rotating block 307. Each bidirectional threaded rod 306 has a dovetail block 305 threadedly connected to its surface. The surface of the dovetail block 305 is movably connected to the inner cavity of the extension plate 302. A clamping block 308 is fixedly connected to the bottom of the dovetail block 305. The inner cavity of the clamping block 308 is in contact with the surface of the support rod 202. The dovetail block 305, bidirectional threaded rod 306, rotating block 307 and clamping block 308 work together. By rotating the rotating block 307, the bidirectional threaded rod 306 is moved, which indirectly moves the dovetail block 305 and clamping block 308 to the inner side of the corresponding support rod 202 until they are in close contact with the surface of the support rod 202, thereby fixing the position of the extension plate 302.

[0028] Reference Figure 4 Each extension plate 302 has a dovetail groove 310 at its bottom. The inner cavity of the dovetail groove 310 is movably connected to the surface of the dovetail block 305. The dovetail groove 310 serves to limit and guide the sliding of the dovetail block 305 in the inner cavity of the extension plate 302, thus restricting the rotation of the dovetail block 305 in the inner cavity of the extension plate 302. Therefore, when the bidirectional threaded rod 306 rotates, it can drive the dovetail block 305 to slide inward or outward at the same time, indirectly driving the clamping block 308 to fix and clamp the support rod 202.

[0029] Reference Figure 4 The surface of the bidirectional threaded rod 306 is fixedly connected with a sliding groove 304. The outer ring of the sliding groove 304 is fixedly connected to the inner cavity of the dovetail groove 310. By setting the sliding groove 304, the rotation position of the bidirectional threaded rod 306 is fixedly limited without affecting the rotation of the bidirectional threaded rod 306, so as to prevent the bidirectional threaded rod 306 from detaching from the inner cavity of the extension plate 302.

[0030] Reference Figure 4A damping pad 309 is fixedly connected to the inner side of the clamping block 308. The damping pad 309 is made of rubber. The surface of the damping pad 309 is in contact with the surface of the extension plate 302. The damping pad 309 increases the friction between the inner side of the clamping block 308 and the surface of the support rod 202, thereby increasing the stability of the clamping block 308 in fixing and clamping the support rod 202.

[0031] Working principle: During the installation of the cantilever scaffolding, the I-beam 204 is first fixed to the surface of the building's exterior wall 1 with bolts. Then, the vertical rod 201, support rod 202, and horizontal rod 203 are connected together by connecting blocks. This is existing technology and will not be elaborated further. Next, the extension plate 302 is pulled, extending it from the inner cavity of the support plate 301. The extension plate 302 drives the sliding block 303 to slide within the inner cavity of the sliding groove 304 in the support plate 301 until the surface of the sliding block 303 contacts the surface of the stop block 311. The extension plate 302 slides outward from the inner cavity of the support plate 301 to its maximum extent. Then, the rotating block 307 is turned, driving the double... As the threaded rod 306 rotates, the position of the dovetail block 305 is restricted by the dovetail groove 310 in the inner cavity of the extension plate 302. Therefore, when the bidirectional threaded rod 306 rotates, it can drive the dovetail block 305 to move inward to the corresponding support rod 202. The dovetail block 305 drives the clamping block 308 to move, and the clamping block 308 drives the damping pad 309 to move until the inner side of the damping pad 309 is in close contact with the surface of the support rod 202. The clamping of the support rod 202 by the clamping block 308 and the increase of the friction between the inner side of the clamping block 308 and the support rod 202 by the damping pad 309 can fix the extension plate 302 on the surface of the support rod 202 for workers to step on for support.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
