Description

Technical Field

[0001] This utility model relates to scaffolding, specifically an adjustable scaffolding for construction. Background Technology

[0002] Scaffolding is a commonly used tool in the construction and decoration industries. Its purpose is to provide stable support to facilitate workers' high-level construction needs. Scaffolding is not a single piece; it needs to be flexibly assembled according to the actual needs of the site.

[0003] For example, Chinese authorized patent CN104372923B, published on 2016-06-08, discloses a type of scaffolding, including uprights, long horizontal tubes, a first connecting coupler, a second connecting coupler, and a support plate. Both the uprights and the long horizontal tubes are seamless square tubes, with through holes at both ends of the long horizontal tubes. The first connecting coupler is a coaxial double-hinged structure, and the second connecting coupler is a hinge structure with a double-bolt connection. A base is fixed to the side of the hinge structure, and a protrusion extends axially from the base along the hinge structure, the protrusion matching the size of the through hole. The support plate is a flat plate structure, with hooks extending downwards from the upper parts of both sides. This invention utilizes the first connecting coupler to connect two uprights, which is convenient, quick, and saves materials; then, the second connecting coupler is used to fix the long horizontal tube to the uprights; and finally, the support plate is hung on the long horizontal tube, serving both a load-bearing function and a connecting function in the scaffolding, making scaffolding construction convenient and easy.

[0004] In existing technologies, including the aforementioned patents, such flexible combination structures typically use circular steel pipes as the main body, and connect and assemble the pipes using fasteners and other fixing devices to form a complete support system. In this type of structure, the performance of the fasteners and other connectors directly determines the connection strength at the assembly nodes. If the support is subjected to uneven loads, these fasteners pose a risk of structural failure or even collapse, potentially leading to the disintegration of the entire support system. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable scaffold for construction, in order to overcome the aforementioned shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable scaffold for construction, comprising: A short-axis steel pipe with symmetrical perforations on its adjacent two ends; The clamping component includes a first tenon that is inserted into the end of the short shaft steel pipe, and the first tenon has an embedded groove corresponding to the through hole. The C-type fastener includes a C-type groove, and an insert block that can pass through the through hole and be embedded in the insert groove is fixedly provided on the inner wall of the C-type groove.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] Please see Figure 1-4 This utility model provides a technical solution: an adjustable scaffold for construction, which includes a short-axis steel pipe 1, a long-axis steel pipe 4, a diagonal steel pipe 6, and fasteners. The fasteners include clamps 2 and C-type buckles 3. The long-axis steel pipe 4 and the short-axis steel pipe 1 can be assembled to form the side support of the scaffold. Then, by pulling the diagonal steel pipe 6, the three-dimensional structure of the support is formed. Finally, planks are placed on the scaffold for workers to step on.

[0020] Specifically, in the above embodiments: like Figure 3 and Figure 4 As shown, the clamp 2 includes a first tenon 21 that is inserted into the end of the short shaft steel pipe 1, a fixing claw 22 that is fixed to the first tenon 21, and a hinge claw 23 that is hinged to the fixing claw. The first tenon 21 has four insertion slots 211, which are arranged in pairs and symmetrically distributed.

[0021] like Figure 2 As shown, the C-type fastener 3 includes a C-type groove 31 and a second tenon insert 32. An insert block 311 is fixedly welded to the inner wall of the C-type groove 31, and the insert block 311 can be inserted into the insert groove 211. The two are in the same number and position. Furthermore, in the embodiment, a movable tongue 33 is rotatably provided in the port on one side of the C-type groove 31.

[0022] Working principle: When assembling, the clamp is first held onto the long shaft steel pipe 4 by the hinge claw 23 and the fixing claw 22, and then fixed by the bolts inserted through the protrusion. The clamp 2 installed on the long shaft steel pipe 4 needs to be measured in advance to ensure that the installation spacing meets the requirements.

[0023] Then, insert the first tenon 21 into the port of the short-axis steel pipe 1. Then, insert the second tenon 32 into the port of the inclined steel pipe 5, and fix the second tenon 32 with the bolts threaded on the inclined steel pipe 5. Then, clamp the C-shaped groove 31 into the short-axis steel pipe 1, at which point the movable tongue 33 abuts against the outer wall of the short-axis steel pipe 1.

[0024] During the process of the C-shaped groove 31 being inserted into the short-axis steel pipe 1, the insert block 311 will pass through the symmetrical perforations on the sides of the adjacent ends of the short-axis steel pipe 1 and then be inserted into the insert groove 211.

[0025] In the above technology, the C-shaped groove 31 of the C-shaped fastener 3 is engaged with the side wall of the short-axis steel pipe 1, and then the insert block 311 passes through the through hole and enters the insert groove 211 on the first tenon 21 at the end of the short-axis steel pipe 1. The interlocking design of the three components increases the integrity of the assembled unit.

[0026] As a further embodiment of this utility model, combined with Figure 4 It can be seen that concave keys are provided on the inner wall of the short-axis steel pipe 1. Two sets of concave keys are provided along the axial direction, and the two sets are kept at a predetermined distance to form a cavity. The aforementioned concave keys are formed by stamping from the outside to the inside of the short-axis steel pipe 1.

[0027] Furthermore, an arc-shaped locking block 6 that moves outward from the axis is slidably disposed on the first tenon insertion part 21, and a lever 7 is rotatably disposed inside the first tenon insertion part 21, one end of which extends to the bottom of the arc-shaped locking block 6 and is slidably connected to it as end a, while the other end extends to the embedded groove 211 as end b.

[0028] Working principle: When the embedded block 311 passes through the symmetrical perforations 11 on the sides of the adjacent ends of the short shaft steel pipe 1 and then is embedded in the embedded groove 211, it will press down on end b, causing end a to move up, thereby lifting the arc-shaped locking block 6 to move outward to abut against the short shaft steel pipe 1 and be located in cavity one.

[0029] It should be noted that there are at least two arc-shaped card blocks 6, arranged in a circular array. Furthermore, in actual use, only one arc-shaped card block 6 is in the active state; that is, only one arc-shaped card block 6 is active.

[0030] Furthermore, a rubber pad is fixedly installed on the outer side of the arc-shaped locking block 6 to increase the damping force after contact with the inside of the short-axis steel tube 1.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
