Description

Technical Field

[0001] The utility model relates to the technical field of scaffolds, in particular to a disc-lock scaffold. Background Art

[0002] Scaffolding is a working platform set up to ensure the smooth progress of each construction process. According to the structural form, it is divided into continuous fastener scaffolding, bowl-hook scaffolding, and disc-hook scaffolding. Among them, disc-hook scaffolding, as an upgraded product, has the advantages of easy and fast construction, so it can meet a wide range of operational needs. In addition, the parts are miniaturized, and the disassembly and storage take up little space. It can pass through various narrow passages, is easy to transport, and is widely used.

[0003] The disc-lock scaffolding usually uses vertical poles and horizontal poles as the main components. Among them, the vertical poles are made by welding a disc on the steel pipe at a certain distance to fix the horizontal pole, and the horizontal pole is made of clamps with pins welded on both ends of the steel pipe. However, the vertical poles and horizontal poles of the existing disc-lock scaffolding are fixedly connected by inserting pins after the calipers cooperate with the buckle discs. The force-bearing components in the connection area of ​​this fixing method are relatively simple. Under certain special working conditions, the connection strength is insufficient. For example, the utility model patent with authorization announcement number CN218438182U discloses "a disc-lock scaffolding reinforced horizontal pole". The disc-lock connecting head has a clamping mouth for a chuck arranged on the scaffold to be clamped, and the chuck is provided with a plurality of limiting holes along the circumferential direction; the disc-lock connecting head is provided with a limiting plug-in hole that passes through the clamping mouth up and down and at the same time, and the limiting plug-in hole is used to connect the limiting plug-in; when the disc-lock scaffold is connected to the reinforcing horizontal pole, the reinforcing horizontal pole is clamped with the chuck on the scaffold through the clamping mouth of the disc-lock connecting head, and the limiting plug-in passes through the limiting plug-in hole of the clamping mouth and the limiting hole of the chuck from top to bottom in sequence. The technical solution is to rely on the engagement of the nozzle and the chuck and then insert the limit plug-in to fix the vertical pole and the horizontal pole. Although a reinforced horizontal pole is used, the connection position between the vertical pole and the horizontal pole still has the problem of insufficient strength. Utility Model Content

[0004] In view of the defects of the prior art, the utility model provides a disc-lock scaffolding, which is provided with a limiting block, which can limit the top of the caliper and share part of the stress, thereby improving the reliability of the disc-lock scaffolding.

[0005] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is a disc-lock scaffolding, which includes a vertical pole assembly, a connecting assembly, a cross bar assembly and a limit piece; the vertical pole assembly includes a plurality of vertical poles; the connecting assembly includes a connecting sleeve fixed between adjacent vertical poles, a snap plate coaxially fixed to the outer diameter of the connecting sleeve, and a limit block fixed to the outer diameter of the connecting sleeve and located above the snap plate, a clamping groove is formed between the snap plate and the limit block, and a plurality of fixing holes are opened through the snap plate; the cross bar assembly includes a plurality of cross bars, each of which has a clamping piece for clamping with the snap plate at both ends, and a limiting hole is opened through the clamping piece; the limiting piece includes a limiting insert; when assembly is completed, the limiting insert is inserted into the limiting hole and the fixing hole at the same time to fix the relative position of the vertical pole and the cross bar, and at least part of the clamping piece is limited inside the clamping groove.

[0006] Furthermore, the limit block is threadedly connected to the connecting sleeve to adjust the distance between the limit block and the buckle plate.

[0007] Furthermore, a limiting groove is formed on the end surface of the limiting block which is away from the buckle plate.

[0008] Furthermore, the limiting member includes a connecting piece, a limiting insert fixed vertically to the connecting piece, and a limiting protrusion fixed to the connecting piece; when assembly is completed, the limiting protrusion is embedded in the limiting groove to limit the limiting member in the length direction of the cross bar.

[0009] Furthermore, the limiting protrusion includes a limiting bolt detachably mounted on the connecting piece.

[0010] Furthermore, the inner diameter of the connecting piece is set to be an arc edge.

[0011] Furthermore, the limiting member includes a limiting ring piece that can be sleeved on the outside of the connecting sleeve, at least two limiting inserts are fixed on the side of the limiting ring piece facing the buckle disk, and a limiting protrusion is fixed on the side of the limiting ring piece facing the buckle disk.

[0012] Furthermore, the limiting protrusion includes a plurality of limiting bolts threadedly connected to the limiting ring piece.

[0013] Furthermore, the limiting protrusion comprises a limiting protrusion ring concentrically welded to the limiting ring piece.

[0014] Furthermore, four limiting inserts are provided and are 90 degrees to each other.

[0015] The beneficial effects of the utility model are as follows: in addition to the buckle disk being arranged on the connecting sleeve, the utility model also arranges a limiting block, and a clamping groove is formed between the buckle disk and the limiting block. After the entire buckle scaffold is assembled, the limiting insert is inserted into the limiting hole and the fixing hole in sequence to fix the relative position of the vertical pole and the horizontal pole, and at least part of the clamp is limited inside the clamping groove, specifically between the upper surface of the buckle disk and the lower surface of the limiting block. There is a small gap between the limiting block and the top of the clamp. When the middle position of the horizontal pole is slightly deformed and bent, the clamp fixed at the end of the horizontal pole will slightly warp up. At this time, the limiting block can limit the top of the clamp and share part of the stress, that is, part of the limiting is achieved by the cooperation of the limiting insert and the hole, and the other part of the limiting is completed by the clamping groove formed between the limiting block and the buckle disk. The strength of the connection position between the vertical pole and the horizontal pole is increased, the stability of the connection is improved, and the reliability of the buckle scaffold is thereby improved.

[0035] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0036] See also Figure 1-Figure 4 , shows a disc-lock scaffold 10 in one embodiment of the utility model, which is used to assist in building construction, and specifically includes a vertical pole assembly 100, a connecting assembly 200, a cross bar assembly 300 and a limiting member 400; the bottom of the vertical pole assembly 100 is fixed to the base concrete or asphalt base surface 30 through a base 20, and the vertical pole assembly 100 is fixedly connected to the cross bar assembly 300 through the connecting assembly 200 and the limiting member 400, and the disc-lock scaffold 10 is formed after assembly is completed.

[0037] Continue to see Figure 1The vertical pole assembly 100 includes a plurality of vertical poles 110; the connecting assembly 200 includes a connecting sleeve 210 fixed between adjacent vertical poles 110, a buckle plate 220 coaxially fixed to the outer diameter of the connecting sleeve 210, and a limit block 230 fixed to the outer diameter of the connecting sleeve 210 and located above the buckle plate 220, a clamping groove a is formed between the buckle plate 220 and the limit block 230, and a plurality of fixing holes 221 are formed through the buckle plate 220; the cross bar assembly 300 It includes multiple cross bars 310, and each of the two ends of the cross bar 310 is respectively fixed with a clamp member 320 for engaging with the buckle plate 220, and a limiting hole 321 is opened through the clamp member 320; the limiting member 400 includes a limiting insert 410; when the assembly is completed, the limiting insert 410 is inserted into the limiting hole 321 and the fixing hole 221 at the same time to fix the relative position of the vertical pole 110 and the cross bar 310, and at least part of the clamp member 320 is limited inside the engaging groove a.

[0038] In addition to the buckle plate 220, the above-mentioned buckle scaffold 10 is also provided with a limit block 230, and a clamping groove a is formed between the buckle plate 220 and the limit block 230. When the entire buckle scaffold 10 is assembled, the limit insert 410 is inserted into the limit hole 321 and the fixing hole 221 in sequence to fix the relative position of the vertical pole 110 and the horizontal pole 310, and at least part of the clamp 320 is limited inside the clamping groove a, specifically, between the upper surface of the buckle plate 220 and the lower surface of the limit block 230. There is a tiny gap between the limit block 230 and the top of the clamp member 320. When the middle position of the cross bar 310 is slightly deformed, the clamp member 320 fixed at the end of the cross bar 310 will slightly warp up. At this time, the limit block 230 can limit the top of the clamp member 320 and share part of the stress, that is, part of the limit is achieved by the cooperation between the limit insert 410 and the hole, and the other part of the limit is completed by the engaging groove a formed between the limit block 230 and the buckle plate 220. The strength of the connection position between the vertical pole 110 and the cross bar 310 is increased, which improves the stability of the connection, thereby improving the reliability of the buckle scaffolding 10.

[0039] See also Figure 2 In one embodiment, the limit block 230 is threadedly connected to the connecting sleeve 210 to adjust the distance between the limit block 230 and the buckle plate 220. When so configured, the relative position of the limit block 230 and the connecting sleeve 210 can be adjusted according to the size of the clamp member 320, that is, the width of the engaging groove a can be adjusted to better limit the clamp member 320. For example, before assembly, the limit block 230 is adjusted to the dotted line position to facilitate the end of the clamp member 320 to be engaged with the buckle plate 220. After the engagement is completed, the limit block 230 is rotated and moved downward to be adjusted to a suitable position. The application range of the buckle scaffold 10 is wider and it is easy to assemble. In a simple working condition where the limit block 230 is not required for limiting, the limit block 230 can also be removed from the connecting sleeve 210.

[0040] See also Figure 5 and Figure 6 In one embodiment, a limiting groove 231 is formed on the end surface of the limiting block 230 away from the buckle plate 220 .

[0041] On the basis of the above embodiment, further, in one embodiment, the limiting member 400 includes a connecting piece 420, a limiting insert 410 vertically fixed to the connecting piece 420, and a first limiting protrusion 430 fixed to the connecting piece 420; when assembled, the first limiting protrusion 430 is embedded in the limiting groove 231 to limit the limiting member 400 in the length direction of the crossbar 310. In one embodiment, the first limiting protrusion 430 includes a limiting bolt detachably mounted on the connecting piece 420.

[0042] See also Figure 7 and Figure 8 In one embodiment, the inner diameter of the connecting piece 420 is set to be an arc edge.

When the cross bar 310 tends to move away from the vertical bar 110, in addition to the limit of the limit insert 410, the first limit convex portion 430 will also produce constraints, which can further share part of the stress, thereby improving the stability of the device. It should be noted that, in addition to being set as a limit bolt connected by a thread, the first limit convex portion 430 can also be set as a limit pin or a limit convex column welded to the bottom of the connecting piece 420.

[0044] See also Fig. 9 and Fig.10 On the basis of the limiting groove 231 being provided in the limiting block 230, further, in another embodiment, the limiting member 400 includes a limiting ring piece 440 that can be sleeved on the outside of the connecting sleeve 210, at least two limiting inserts 410 are fixed on the side of the limiting ring piece 440 facing the buckle plate 220, and a second limiting protrusion 450 is fixed on the side of the limiting ring piece 440 facing the buckle plate 220. In one embodiment, the second limiting protrusion 450 includes a plurality of limiting bolts threadedly connected to the limiting ring piece 440. In one embodiment, the second limiting protrusion 450 includes a limiting protrusion concentrically welded to the limiting ring piece 440.

When the cross bar 310 tends to move away from the vertical bar 110, in addition to the limit of the limit insert 410, the second limit convex portion 450 will also produce constraints, which can further share part of the stress, thereby improving the stability of the device. It should be noted that in addition to being set as a limit convex ring, the second limit convex portion 450 can also be set as a plurality of limit bolts connected by threads, or a plurality of limit convex blocks distributed at equal intervals.

[0046] See also Fig.10 In one embodiment, four limiting inserts 410 are provided, and they are 90° to each other. When assembling, adjacent limiting inserts 410 are at right angles to each other, constraining adjacent cross bars 310 to be at right angles, which can avoid misaligned installation to a certain extent, and when spare parts are needed, the limiting ring piece 440 can be sleeved on the outside of the connecting sleeve 210 to prepare together, and be transported and stored together, so as to avoid the problem that the limiting inserts 410 are small in size and easy to be lost when stored and transported independently.
