Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a gradient pipe formwork support device. Background Technology

[0002] In the coal mine merger and reorganization project of Shanxi Xinzhou Shenda Wanxin Anping Coal Industry Co., Ltd., the entrance of the ventilation fan room's air duct is circular, and the diameter gradually increases as the entrance moves inward. This structural design can better adapt to ventilation needs and improve ventilation efficiency.

[0003] However, in construction, traditional support systems have the problem of cumbersome assembly processes. For "gradual" structures, a lot of time and manpower are required for adjustment and assembly, resulting in low construction efficiency and extended construction period.

[0004] Therefore, we provide a gradient pipe template support device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a gradient pipe template support device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gradient pipe template support device, comprising a support rod, on which support frames are equidistantly installed, the support frames being composed of several radially arranged telescopic large support rods, a support ring being installed on each of the large support rods, and several slidable support keys being installed on each of the support rings.

[0007] As a further supplement to the above technical solution, a collar is installed at one end of each of the large support rods, and the large support rods are coaxially stacked and connected through the collars.

[0008] As a further supplement to the above technical solution, a limiting groove is provided on each of the collars to ensure that the included angle of the fixed large support rod remains unchanged.

[0009] As a further supplement to the above technical solution, each of the large support rods can be divided into two equal small support rods. A strip-shaped hole is provided on the small support rod, and the overlapping sections of the two small support rods are connected to each other by bolts passing through the strip-shaped hole in sequence.

[0010] As a further supplement to the above technical solution, each of the support rings is provided with a strip-shaped ring hole, and the support key is installed on the support ring at equal intervals by bolts passing through the strip-shaped ring hole.

[0011] As a further supplement to the above technical solution, a second strip hole is provided on the support key, and the support key is slidably connected to the support ring by a bolt passing through the second strip hole.

[0012] As a further supplement to the above technical solution, a limiting ring is provided at one end of the support rod, a limiting nut is screwed to the other end of the support rod, and a limiting sleeve is sleeved on the support rod. The limiting sleeve is used to ensure that the spacing of the support frame is consistent.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a limiting sleeve to install a support structure equidistantly on the support rod. The support structure consists of a telescopic large support rod, a support ring, and a support key. The large support rod is coaxially stacked together through a collar and arranged radially through a limiting groove. The support key directly abuts against the template and can adjust the relative position of the support key and the support ring to make the support key fit the template better.

[0021] To further illustrate the technical solution of this utility model, the following description is in conjunction with the appendix. Figures 1 to 5 The present invention will be further described in detail through four embodiments.

[0022] Example 1

[0023] This embodiment provides a gradient pipe template support device, as shown in the attached figure. Figure 1As shown, the device includes a support rod 1, on which support frames 2 are installed at equal intervals. The support frames 2 are composed of several radially arranged telescopic large support rods 3. A support ring 4 is installed on each large support rod 3, and several slidable support keys 5 are installed on each support ring 4.

[0024] Example 2

[0025] Based on Example 1, as shown in the appendix Figure 2 and 3 As shown, we install a collar 6 at one end of each large support rod 3, and the large support rods 3 are connected by being coaxially stacked through the collars 6; we open a limiting groove 601 on each collar 6, the limiting groove 601 is used to ensure that the included angle of the fixed large support rod 3 remains unchanged.

[0026] Furthermore, each large support rod 3 can be divided into two equal small support rods 7. A strip hole 701 is provided on the small support rod 7. The overlapping sections of the two small support rods 7 are connected by bolts 8 passing through the strip hole 701 in sequence.

[0027] Example 3

[0028] Based on Embodiment 1 and Embodiment 2, as shown in the appendix Figure 4 As shown, we have a strip-shaped annular hole 9 on each support ring 4, and the support key 5 is installed on the support ring 4 at equal intervals by bolts 10 passing through the strip-shaped annular hole 9; we have a strip-shaped hole 11 on the support key 5, and the support key 5 is slidably connected to the support ring 4 by bolts 10 passing through the strip-shaped hole 11.

[0029] Example 4

[0030] Based on the above embodiments, as shown in the appendix Figure 4 As shown, a limiting ring 101 is provided at one end of the support rod 1, a limiting nut 12 is screwed to the other end of the support rod 1, and a limiting sleeve 13 is sleeved on the support rod 1. The limiting sleeve 13 is used to ensure that the spacing of the support frame 2 is consistent.

[0031] Working principle:

[0032] Based on the length of the limiting cylinder 13, the ventilation duct is divided into multiple spaces, and the corresponding number of supporting parts are selected for assembly according to the number of spaces.

[0033] First, the large support rods 3 are stacked together coaxially through the collar 6, and the included angle of the adjacent large support rods 3 is fixed by the limiting groove 601 on the collar 6 to form a support structure. Then, the support rods 1 are passed through the support structure and the limiting cylinder 13 at intervals. Finally, the support structure and the limiting cylinder 13 are firmly installed on the support rods 1 by screwing the limiting nut 12 to the support rods 1.

[0034] Next, according to the gradual change in the diameter of the ventilation duct, the length of the large support rod 3 is extended in sequence so that the support key 5 on the support ring 4 can abut against the template. The overlapping section length of the two small support rods 7 that make up the large support rod 3 is adjusted. The shorter the overlapping section, the longer the adjusted large support rod 3. Then, by adjusting the relative position of the strip hole 11 and the strip ring hole 9, the support key 5 is made to fit the template more closely.
