[0011] Further, two mounting frames are symmetrically arranged on each connecting cylinder.

[0012] By adopting the technical scheme, two mounting frames are arranged, and two second rod bodies are arranged corresponding to the second structural member, so that the connection strength between the fixing member and the connecting member can be enhanced, and the scaffold structure also has good overall strength in a narrow and thick groove in which only a single row of scaffolds can be arranged.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. After erecting the vertical pole, align the mounting groove on the connecting tube with the positioning block on the vertical pole, and then slide the connecting tube down to the desired position.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0033] This embodiment provides a scaffolding structure in a narrow manure trough, so as to facilitate the installation of the scaffolding in the narrow manure trough.

[0034] Overall structure, refer to Figures 1 to 4 The narrow and deep groove inner scaffold structure of the embodiment includes a plurality of spaced upright poles 1 arranged at the bottom of the deep groove, a connecting piece 2 arranged on the upright pole 1, a first structural piece 3 connecting adjacent upright poles 1 through the connecting piece 2, a fixing piece 4 fixed on the side wall 100 of the foundation pit, and a second structural piece 5 connecting the fixing piece 4 and the upright pole 1 through the connecting piece 2. A plurality of positioning blocks 11 are arranged on the side wall of the upright pole 1 away from the side wall 100 of the foundation pit in an axial direction. The connecting piece 2 includes a connecting cylinder 21 sleeved on the upright pole 1, and a mounting frame 22 for connecting the first structural piece 3 or the second structural piece 5. A first annular groove 211 is arranged around the connecting cylinder 21, a first mounting groove 212 is arranged on the connecting cylinder 21 and penetrates and communicates with all the first annular grooves 211 in the axial direction, and the positioning block 11 can slide along the first mounting groove 212 or the first annular groove 211. The mounting frame 22 is screwed and penetrates the connecting cylinder 21 in the radial direction, and can abut against the upright pole 1 to lock the connecting cylinder 21.

[0035] As arranged above, after the upright pole 1 is erected, the mounting groove on the connecting cylinder 21 is aligned with the positioning block 11 on the upright pole 1, the connecting cylinder 21 can be slid downward to the required position, then the annular groove in the connecting cylinder 21 is adjusted to be aligned with the positioning block 11, the connecting cylinder 21 is rotated, the positioning block 11 in the connecting cylinder 21 is transferred from the mounting groove to the annular groove, the height of the connecting cylinder 21 on the upright pole 1 is preliminarily locked, then the mounting frame 22 is screwed to abut against the upright pole 1, and the corresponding first structural piece 3 and second structural piece 5 can be installed. The positioning block 11 and the connecting cylinder 21 are arranged to cooperate to lock the height of the connecting piece 2, which can facilitate the installation of the scaffold in the narrow and deep groove.

[0036] Based on the above overall introduction, specifically, the scaffold structure of the embodiment is arranged between the side wall 100 of the foundation pit and the outer wall 200 of the building, the side wall 100 of the foundation pit is vertically arranged, and the specific form can adopt the type of slope protection pile. The fixing piece 4 is arranged in multiple in the depth direction of the deep groove. Three annular grooves are arranged in the connecting cylinder 21, which can stably connect the upright pole 1 in cooperation with the positioning block 11.

[0037] As a preferred implementation form, the mounting frame 22 has a rectangular through hole 71 through which the first structural piece 3 or the second structural piece 5 passes, and when the mounting frame 22 abuts against the upright pole 1, the rectangular through hole 71 faces the horizontal direction. The locking bolt 23 is screwed through the mounting frame 22, and after being fastened, the locking bolt 23 can press the first structural piece 3 or the second structural piece 5.

[0038] It is understandable that after the installation frame 22 is screwed into place, its rectangular through hole 71 faces the horizontal direction, which is the same as the final installation direction of the first structural member 3 and the second structure. After tightening the locking bolt 23, the corresponding first structural member 3 or second structural member 5 can be locked and fixed. Secondly, the first structural member 3 or the second structural member 5 is inserted into the installation frame 22. The frame can be pressed against the vertical pole 1 by rotating the first structural member 3 or the second structural member 5, which can increase the force arm. A positioning concave stop is provided on the connecting tube 21, and a positioning convex stop is provided on the installation frame 22. A stud is welded on the positioning convex stop. The positioning convex stop is inserted into the positioning concave stop. The stud is screwed and passed through the connecting tube 21, which can align and press the vertical pole 1, making the connecting member 2 less likely to shake and the scaffolding as a whole more stable.

[0039] As for the specific structure of the fixing member 4, the fixing member 4 of this embodiment includes a fixing seat 41 pre-buried on the foundation pit side wall 100, and a threaded sleeve 42 fixedly connected to the fixing seat 41. The second structural member 5 includes a connecting pipe 51 sleeved outside the threaded sleeve 42, a second rod body 52 pivotally connected to the connecting pipe 51 along the radial direction of the connecting pipe 51, and a pressure cover 53 screwed on the threaded sleeve 42. The second rod body 52 is passed through the installation frame 22 and is tightened by the locking bolt 23. After the pressure cover 53 is tightened, it can press the connecting pipe 51 on the fixing seat 41. The fixing seat 41 can be originally installed on the foundation pit side wall 100 using an anchor bolt. It has a rectangular plate at one end outside the foundation pit side wall 100 that fits the foundation pit side wall 100, and the threaded sleeve 42 is vertically welded to the rectangular plate.

[0040] Based on the above configuration, when the foundation pit sidewall 100 has a slope, for example Figure 5 In the embodiment of the present invention, shotcrete is cured on the foundation pit sidewall 100. The projection of the central axis of the threaded sleeve 42 on the bottom of the fertilizer trough is perpendicular to the direction of the fertilizer trough, and the central axis of the threaded sleeve 42 is not perpendicular to the vertical pole 1. By pivoting the connecting pipe 51 to the second rod 52, the angle of the connecting pipe 51 can be adjusted according to the slope of the foundation pit sidewall 100. By connecting the connecting pipe 51 in accordance with the angle of the threaded sleeve 42 and using the gland 53 to tighten the connecting pipe 51, the adaptability of the scaffolding structure to foundation pit sidewalls 100 at different angles can be enhanced.

[0041] Preferably, refer to Figure 3 and Figure 4 As shown, two mounting frames 22 are symmetrically provided on each connecting tube 21. Providing two mounting frames 22, corresponding to two second rods 52 of the second structural member 5, can enhance the connection strength between the fixing member 4 and the connecting member 2. Even in a narrow slot where only a single row of scaffolding can be installed, the scaffolding structure also has good overall strength.

[0042] Further, the second structural member 5 further comprises a structural rod 54 penetrating through the connecting pipe 51 in the radial direction, two second rod bodies 52 are connected to the two ends of the structural rod 54 respectively, and the end of the threaded sleeve 42 away from the fixing base 41 is provided with an accommodating groove 421 capable of accommodating the structural rod 54. It should be noted that the structural rod 54 can make the two second rod bodies 52 of the same second structural member 5 rotate synchronously, after the structural rod 54 is aligned with the accommodating groove 421 and is put in, the connecting pipe 51 is also sleeved on the threaded sleeve 42, without hand holding, the installation can be completed by fastening the gland 53 on the threaded sleeve 42 to the right position.

[0043] As a preferred implementation form, referring to Figure 2 and Figure 6 , the first structural member 3 is a rod body with a rectangular cross section, and a plurality of insertion grooves 31 are arranged along the length direction of the first structural member 3, and the locking bolt 23 can be inserted into the insertion groove 31. By such an arrangement, the insertion of the locking bolt 23 into the insertion groove 31 can further enhance the connection strength between the first structural member 3 and the connecting member 2, and make the scaffold structure more firm. At the same time, two first structural members 3 are arranged between the connecting members 2 on the adjacent two stand poles 1, and the insertion grooves 31 can also facilitate the determination of the installation positions of the two first structural members 3 and the connecting member 2 by the number of insertion grooves 31, so as to ensure that the spacing between the two installation members is consistent.

[0044] As a preferred implementation form, referring to Figure 2 and Figure 7 , the scaffold structure comprises a support member 6 arranged on the stand pole 1, and a footboard 7 detachably connected to the support member 6. The support member 6 comprises a support cylinder 61 sleeved on the stand pole 1, and a support arm 62 fixedly connected to the support cylinder 61, a second annular groove 611 is arranged around the support cylinder 61, a second installation groove 612 is arranged on the support cylinder 61 and penetrates through and communicates with all the second annular grooves 611 in the axial direction, and the positioning block 11 can slide along the first annular groove 211 or the second installation groove 612. It should be noted that when the support member 6 is installed, as long as the second installation groove 612 is aligned with the positioning block 11 and is sleeved downward to the required position, the support member 6 is adjusted so that the second annular groove 611 is aligned with the installation block, and is rotated to the side away from the side wall 100 of the foundation pit, after the two support members 6 are installed in place, the footboard 7 is installed on the support arms 62 of the two support members 6, and the installation and fixation of the footboard 7 can be completed, which is convenient and fast. In the embodiment, three second annular grooves 611 are arranged in the support cylinder 61.

[0045] Specifically, the scaffolding structure includes mounting nails 8. The scaffolding boards 7 are provided with through-holes 71. The heads of the mounting nails 8 pass through the through-holes 71 and engage the support arms 62. Each support arm 62 is provided with at least two mounting nails 8. The mounting nails 8, when engaged between the scaffolding boards 7 and the support arms 62, constrain the scaffolding boards 7 to the support arms 62, preventing them from sliding toward or away from the pit sidewalls 100. Furthermore, the mounting nails 8 constrain the two support arms 62, which are supported by the scaffolding boards 7, and prevent them from excessively rotating, which could affect their usability. In this embodiment, each support arm 62 is provided with three mounting nails 8.

[0046] Preferably, the upper surface of the scaffolding board 7 is provided with a receiving groove 72, and the through-hole 71 is provided at the bottom of the groove 72, so that the mounting nail 8 does not protrude from the upper surface of the scaffolding board 7. The provision of the receiving groove 72 not only accommodates the mounting nail 8, making the upper surface of the scaffolding board 7 relatively flat, but also absorbs rainwater, sand, and other debris, reducing the risk of construction workers slipping due to stepping on debris. In addition, the through-hole 71 can be configured as a waist-shaped hole extending along the length of the scaffolding to facilitate the installation of the mounting nail 8. The multiple scaffolding boards 7 are flush and abut against each other.

The positioning tube 91 is provided with a rotation-stop groove 911 for the positioning block 11 to enter. When the positioning block 11 enters the rotation-stop groove 911, the positioning tube 91 can prevent the upright 1 from rotating. The provision of the support platform 9 can provide a more stable support base for the upright 1, the positioning tube 91 can make the spacing between the uprights 1 more accurate, and the provision of the rotation-stop groove 911 can prevent the upright 1 from rotating, keeping the positioning block 11 always on the side of the upright 1 away from the foundation pit side wall 100. The support platform 9 can be set as an inverted channel steel structure, the back of which is relatively flat, which can facilitate the welding of the positioning tube 91.
