Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a telescopic disc-type scaffolding support rod. Background Art

[0002] In construction projects, disc-type scaffolding is widely used due to its advantages such as easy assembly and disassembly and short erection period. It has largely replaced the coupler-type scaffolding. To facilitate mass production, the horizontal support rods of the disc-type scaffolding have only five standard lengths: 0.3m, 0.6m, 0.9m, 1.2m and 1.5m.

[0003] Although these five lengths meet the erection requirements of most projects, there are still many working conditions where the horizontal spacing of scaffolding poles is not in the modulus. For example, when constructing the oblique support beam at the bottom of the floor slab, the horizontal spacing between the oblique side poles and the right-angle side poles is highly random, and it is difficult for conventional disc-type scaffolding horizontal support poles to meet all erection conditions; in addition, when the scaffolding is erected to adjacent walls or structural columns, there will be problems such as the formwork distance is too short or the horizontal spacing of the scaffolding poles does not meet the modulus. When the horizontal support rods cannot meet the support requirements of irregular spacing, coupler-type scaffolding is often used in combination, which not only increases the difficulty of scaffolding erection, but also brings construction risks due to the mixing of the two formwork systems. Utility Model Content

[0004] The purpose of the utility model is to overcome the defects of the prior art and provide a retractable disc-type scaffolding support rod, by adjusting the threaded sleeve so that the threaded sleeve pushes the pin to move along the sliding groove, thereby realizing the length adjustment of the first connecting rod and the second connecting rod, and when in use, the threaded sleeves on both sides limit the pin to prevent the first connecting rod and the second connecting rod from sliding.

[0005] The technical solution to achieve the above purpose is a retractable disc-type scaffolding support rod, comprising:

[0006] A first connecting rod, one end of which forms a first buckle connection end, a surface of the first connecting rod forms a threaded connection section, the threaded connection section forms a sliding groove along the length direction of the first connecting rod, and a side of the first connecting rod away from the first buckle connection end forms an insertion opening;

[0007] a second connecting rod slidably inserted into the insertion port, the second connecting rod having a sliding hole formed therein corresponding to the sliding groove, an end of the second connecting rod away from the first connecting rod forming a second buckle connection end, and a latch pin inserted into the sliding groove and the sliding hole; and

[0008] Two threaded sleeves are threadedly connected to the threaded connection section and are located on both sides of the pin. By screwing the threaded sleeves, the two threaded sleeves clamp the pin and push against the pin, so that the second connecting rod moves along the length direction of the first connecting rod.

[0009] Furthermore, a plurality of sliding holes are provided.

[0010] Furthermore, the distance between two adjacent sliding holes is twice the length of the sliding groove.

[0011] Furthermore, the length of the threaded connection section is 4 times the length of the sliding groove.

[0012] Furthermore, two sliding grooves are formed, and the two sliding grooves are arranged opposite to each other in the threaded connection section.

[0013] Furthermore, the length of the threaded sleeve is 1.5 times the length of the sliding groove.

[0014] Furthermore, the diameter of the second connecting rod is matched with the inner diameter of the insertion opening.

[0015] Furthermore, the length of the first connecting rod is matched to the length of the second connecting rod.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The threaded sleeve is adjusted so that the threaded sleeve pushes the latch pin to move along the sliding groove, thereby achieving length adjustment of the first connecting rod and the second connecting rod. When in use, the threaded sleeves on both sides limit the latch pin to prevent the first connecting rod and the second connecting rod from sliding. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] See also Figures 1 to 3 , a telescopic disc-type scaffolding support rod, comprising: a first connecting rod 1, one end of the first connecting rod 1 forms a first disc-type connecting end, a surface of the first connecting rod 1 is formed with a threaded connecting section 6, the threaded connecting section 6 is formed with a sliding groove 5 along the length direction of the first connecting rod 1, and the first connecting rod 1 is formed with an insertion opening on the side away from the first disc-type connecting end; a second connecting rod 2 slidably inserted in the insertion opening, the second connecting rod 2 is formed with a sliding hole 7 corresponding to the sliding groove 5, the second connecting rod 2 is formed with a second disc-type connecting end at one end away from the first connecting rod 1, and a latch 4 is inserted in the sliding groove 5 and the sliding hole 7; and two threaded sleeves 3 threadedly connected to the threaded connecting section 6 and located on both sides of the latch 4, by screwing the threaded sleeves, the two threaded sleeves clamp the latch and push against the latch, so that the second connecting rod moves along the length direction of the first connecting rod.

[0024] In the present utility model, a preferred implementation is: the second connecting rod 2 is inserted into the first connecting rod 1 and placed between two adjacent discs of the scaffolding, the pin 4 is inserted into the insertion port and the sliding groove 5, and the threaded sleeve 3 on both sides of the pin 4 is adjusted so that the threaded sleeve 3 can move along the threaded connection section 6 and push the pin 4, so as to accurately adjust the part of the second connecting rod 2 exposed from the first connecting rod 1, and the first disc connection end and the second disc connection end are respectively fixed to the discs of the scaffolding to connect the scaffolding.

[0025] Further, the sliding holes 7 are provided with a plurality of them. Preferably, when the first connecting rod 1 and the second connecting rod 2 are placed between two adjacent buckles of the scaffold, the second connecting rod 2 can be inserted into the first connecting rod 1, and the second connecting rod 2 can be roughly adjusted so that the sum of the exposed length of the second connecting rod 2 and the length of the first connecting rod 1 is almost equal to the distance between the two buckles, the latch 4 can be inserted into the sliding hole 7 located in the sliding groove 5, the inserted latch 4 can be limited by the threaded sleeve 3, the threaded sleeve 3 can be rotated so that the threaded sleeve 3 pushes the latch 4 and drives the second connecting rod 2 to slide along the length direction of the first connecting rod 1, so that the sum of the exposed length of the second connecting rod 2 and the length of the first connecting rod 1 is equal to the distance between the two buckles, and the two threaded sleeves 3 can be screwed to tighten the latch 4 to prevent the second connecting rod 2 from sliding.

[0026] Further, the distance between two adjacent sliding holes 7 is twice the length of the sliding groove 5.

[0029] Furthermore, the length of the threaded sleeve 3 is 1.5 times the length of the sliding groove 5. Preferably, L1=1.5L2.

[0030] Furthermore, the diameter of the second connecting rod 2 is matched with the inner diameter of the insertion opening.

[0031] Furthermore, the length of the first connecting rod 1 is adapted to the length of the second connecting rod 2 .

[0032] The following is an explanation of the use of the telescopic disc-type scaffolding support rod of the utility model.

[0033] When the first connecting rod 1 and the second connecting rod 2 are placed between two adjacent discs of the scaffolding, the second connecting rod 2 can be first inserted into the first connecting rod 1, and the second connecting rod 2 can be roughly adjusted so that the sum of the exposed length of the second connecting rod 2 and the length of the first connecting rod 1 is almost equal to the distance between the two discs, and the latch 4 is inserted into the sliding hole 7 located in the sliding groove 5, and the inserted latch 4 is limited by the threaded sleeve 3, and the threaded sleeve 3 is rotated so that the threaded sleeve 3 pushes the latch 4 and drives the second connecting rod 2 to slide along the length direction of the first connecting rod 1, so that the sum of the exposed length of the second connecting rod 2 and the length of the first connecting rod 1 is equal to the distance between the two discs, and the two threaded sleeves 3 are screwed to tighten the latch 4 to prevent the second connecting rod 2 from sliding. Preferably, the distance between two adjacent sliding holes 7 is twice the length of the sliding groove 5.
