Figure 1As shown, the slope surface steel pipe rack track base structure includes a base 1, a track channel steel 2, a limiting base 3 and a steel pipe frame 4; wherein, multiple groups of the bases 1 are respectively and parallelly fixedly installed on the slope support 5, the track channel steel 2 is arranged on the base 1, and multiple limiting bases 3 are slidably arranged on the track channel steel 2, and the steel pipe frame 4 is plugged and fixed on the limiting bases 3; multiple groups of pedestals 6 are arranged on the slope support 5, and the length of the base 1 matches the spacing between the pedestals 6, so that the upper and lower ends of the multiple groups of the bases 1 can be respectively supported on the pedestals 6; by adjusting the setting position of the track channel steel 2 on the base 1, and adjusting the position of the limiting base 3 on the track channel steel 2, the position adjustment of the steel pipe frame 4 is realized, and the installation of the steel pipe frame 4 is accurately realized to meet the requirements of engineering design.

[0030] In the embodiment of the utility model, the base 1 is an I-beam. For example, the I-beam can be 16# I-beam, which has low cost and certain supporting strength.

[0031] See also Figure 2 As shown, the front and back flanges of the base 1 are respectively provided with staggered positioning holes 10 at intervals, and expansion bolts 9 are arranged in the positioning holes 10 on the front flange. The track channel steel 2 is vertically arranged on the base 1 and fixed to the base 1 by the expansion bolts 9.

[0032] In the embodiment of the utility model, the spacing between the positioning holes 10 can be determined according to actual application requirements, so that it can be suitable for adjusting the position accuracy of the track channel steel 2 in the longitudinal direction in different application scenarios.

[0033] In order to further improve the structural stability of the track channel steel 2 , a limiting bolt 7 is further provided in the corresponding positioning hole 10 above or below the track channel steel 2 to provide a limiting effect and further limit the track channel steel 2 from slipping relative to the base 1 .

[0034] Therefore, the installation position of the steel pipe frame 4 in the longitudinal direction can be adjusted by adjusting the setting position of the track channel steel 2 on the base 1.

[0035] An expansion bolt 9 is arranged in a positioning hole 10 on the flange on the reverse side of the base 1 , and the base 1 and the slope support 5 are connected and fixed by the expansion bolt 9 , so that the base 1 can be stably connected relative to the slope support 5 .

[0036] Combination Figure 3As shown, the track channel steel 2 includes an integrally formed bending portion 21 and a track portion 22, the bending surface of the bending portion 21 is in contact with the flange of the front face of the base 1 and is fixed by the expansion bolt 9, and the side face of the bending portion 21 is vertically connected to the track portion 22; the limiting base 3 includes an integrally formed limiting portion 31 and a supporting portion 32, the limiting portion 31 is buckled on the track portion 22, and the limiting portion 31 can slide on the track portion 22, the supporting portion 32 is arranged at the upper end of the limiting portion 31, and the steel pipe frame 4 is inserted into the limiting portion 31, so that the installation position of the steel pipe frame 4 in the lateral direction can be adjusted by adjusting the position of the limiting portion 31 on the track portion 22.

[0037] In the embodiment of the utility model, the sum of the bending angles formed by the bending surface and the side surface of the bending portion 21 and the slope angle of the slope support 5 is 90°, which can ensure that the track portion 22 is parallel to the ground, so that the setting direction of the steel pipe frame 4 is perpendicular to the ground, which is convenient for providing a force fulcrum to increase the stability of the formwork frame.

[0038] The working principle of the slope steel pipe rack track base structure described in the embodiment of the utility model is specifically as follows:

[0039] According to the rod arrangement diagram of the formwork frame, the position of each steel pipe frame 4 is marked on the slope surface of the slope support 5, and then the base 1 is hoisted to the slope surface, and the base 1 is laid flat on the slope support 5 according to the position of the line, and the expansion bolts 9 are tightened on the concrete surface of the slope surface, and fixed with the base 1 by spot welding;

[0040] When there are caps 6 above and below the slope surface of the slope support 5, the two ends of the base 1 are butted against each other between the upper and lower caps 6 to form a supporting and fixing relationship;

[0041] The position of the track channel steel 2 is fixed on the base 1 by expansion bolts 9 and limit bolts 7 respectively, and the limit base 3 is slidably installed on the track channel steel 2. The steel pipe frame 4 is respectively inserted on the limit base 3, and the installation position of the steel pipe frame 4 is determined according to the rod arrangement diagram of the formwork frame, so as to adjust the position of the limit base 3 accordingly, and accurately realize the installation of the steel pipe frame 4 to meet the requirements of engineering design.

[0042] The sloped steel pipe rack track base structure of the utility model embodiment adjusts the position of the track channel steel 2 on the base 1 and the position of the limit base 3 on the track channel steel 2, thereby respectively adjusting the position of the steel pipe frame 4 in the transverse and longitudinal directions, and accurately installing the steel pipe frame 4 to meet the requirements of engineering design. It is flexible to use and can be used for slopes of various angles. It has strong applicability, stable structure and low cost, and all components are tool-assembled, with high installation and removal efficiency.

[0043] Example 2

[0044] See also Figure 4 As shown, it is a structural schematic diagram of another embodiment of the slope surface steel pipe rack rail base structure of the utility model. In some application scenarios, the slope support 5 may not necessarily be provided with a pedestal 6. In this case, a support node for connecting the base 1 is required on the slope support 5; the upper and lower ends of the base 1 are respectively vertically connected with support rods 8, and the base 1 and the support rods 8 form a frame structure to provide physical support for the track channel steel 2, etc. In the case of no pedestal 6, it can cooperate with the base 1 to form a stable bottom support.
