Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit construction, in particular to a fixed steel collar structure in a foundation pit for building foundation construction. Background Technique

[0002] The foundation pit collar structure is a series of protective structures built around the foundation pit to prevent problems such as soil slope sliding and collapse, ensuring the stability of the foundation pit and the safe and smooth progress of construction.

[0003] Traditional foundation pit collar structures usually rely on manual cleaning when removing gravel on the top of the cleaner, that is, construction workers need to regularly climb up the side wall of the foundation pit and manually clean the gravel and sundries on the top of the retaining board. This method not only has low efficiency and increases construction costs, but also has extremely high safety risks. Once the cleaning is not timely or thorough, the gravel and sundries may accumulate too much, resulting in uneven stress on the collar structure, and then causing serious consequences such as structural deformation or collapse. Therefore, a fixed steel collar structure in a foundation pit for building foundation construction is proposed to solve the above problems. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a fixed steel collar structure in a foundation pit for building foundation construction to overcome the deficiencies in the above prior art.

[0005] The technical solution for the utility model to solve the above technical problems is as follows: A fixed steel collar structure in a foundation pit for building foundation construction, including a foundation pit, and a collar structure is arranged on the side wall of the foundation pit;

[0006] The collar structure includes a plurality of connecting frames fixedly installed on the inner cavity side wall of the foundation pit by bolts. A bearing plate is fixedly installed on the top of the plurality of connecting frames. A concave frame is fixedly installed on the top of the bearing plate. Four support columns are fixedly installed on the bottom of the inner cavity of the concave frame. A lifting plate located inside the concave frame is slidably installed outside the four support columns. Two triangular inclined plates are fixedly installed on the top of the lifting plate. Hollow covers are fixedly installed on both the left and right sides of the concave frame. The triangular inclined plates incline towards the hollow covers. The outer parts of the two hollow covers are triangular structures. Rectangular empty cylinders are movably installed at the discharge ports at the bottoms of the two hollow covers.

[0007] The beneficial effect of the utility model is that: The bearing plate and the concave frame are supported and fixed on the side wall of the foundation pit through a plurality of connecting frames. Personnel can carry out construction operations below the bearing plate. When gravel falls in the foundation pit, it will directly fall on the two triangular inclined plates. The gravel falling on the two triangular inclined plates will slide into the interiors of the two hollow covers. After the gravel enters the interiors of the two hollow covers, it will safely slide down to the ground of the foundation pit through the two rectangular empty cylinders. Therefore, after the device is installed, there is no need for construction workers to regularly clean the gravel and sundries, thus not delaying the construction process of the staff.

[0008] On the basis of the above technical solution, the present utility model can also be improved as follows.

[0009] Further, a plurality of dampers penetrating into the inside of the concave-shaped frame are fixedly installed at the bottom of the bearing plate, and the top telescopic ends of the plurality of dampers are fixedly connected to the bottom of the lifting plate.

[0022] The principles and features of the present invention will be described below in conjunction with the attached drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0023] Example 1, as Figures 1 to 4 shown, a fixed steel purlin structure in a building foundation construction foundation pit includes a foundation pit 1, and a purlin structure is arranged on the side wall of the foundation pit 1.

[0024] The purlin structure includes a plurality of connecting frames 2 fixedly installed on the inner cavity side wall of the foundation pit 1 by bolts. A bearing plate 3 is fixedly installed on the top of the plurality of connecting frames 2. A concave frame 4 is fixedly installed on the top of the bearing plate 3. Four support columns 5 are fixedly installed on the bottom of the inner cavity of the concave frame 4. A lifting plate 6 located inside the concave frame 4 is slidably installed outside the four support columns 5. Two triangular inclined plates 7 are fixedly installed on the top of the lifting plate 6. Hollow covers 8 are fixedly installed on both the left and right sides of the concave frame 4. The triangular inclined plates 7 incline towards the hollow covers 8. The outer parts of the two hollow covers 8 are triangular structures. Rectangular hollow cylinders 9 are movably installed at the bottom discharge ports of the two hollow covers 8.

[0025] During use, the bearing plate 3 and the concave frame 4 are supported and fixed on the side wall of the foundation pit 1 through a plurality of connecting frames 2. Personnel can carry out construction operations below the bearing plate 3. At this time, the plurality of support columns 5 limit the lifting plate 6 inside the concave frame 4. When gravel falls in the foundation pit, it will directly fall on the two triangular inclined plates 7. Since the two triangular inclined plates 7 incline towards the two hollow covers 8 respectively, the gravel falling on the two triangular inclined plates 7 will slide into the interiors of the two hollow covers 8. After the gravel enters the interiors of the two hollow covers 8, it safely slides down to the foundation pit ground through the two rectangular hollow cylinders 9.

[0026] Example 2, as Figure 3 shown, this embodiment is a further improvement based on Example 1, and the specific details are as follows:

[0027] A plurality of dampers 10 penetrating into the interior of the concave frame 4 are fixedly installed at the bottom of the bearing plate 3. The top telescopic ends of the plurality of dampers 10 are fixedly connected to the bottom of the lifting plate 6.

[0028] The bottom of the lifting plate 6 is supported by a plurality of installed dampers 10 to relieve the impact when the crushed stones fall and prevent the crushed stones from bouncing up after falling on the triangular inclined plate 7.

[0029] Embodiment 3, as Figures 1 to 3 shown, this embodiment is a further improvement based on Embodiment 1, and the specific content is as follows:

[0030] On the surfaces of the two triangular inclined plates 7, a first baffle 11 is fixedly installed by bolts, and the height of the first baffle 11 is greater than the height of the triangular inclined plate 7.

[0031] The front of the triangular inclined plate 7 is blocked by the installed first baffle 11 to prevent the crushed stones at the top of the triangular inclined plate 7 from rolling to the outside.

[0032] Embodiment 4, as Figures 1 to 3 shown, this embodiment is a further improvement based on Embodiment 1, and the specific content is as follows:

[0033] On the tops of the two hollow covers 8, second baffles 12 close to their outsides are fixedly installed, and the second baffles 12 are located on the backs of the first baffles 11.

[0034] The outsides of the two hollow covers 8 are protected by the installed two second baffles 12 to prevent the crushed stones at the top of the triangular inclined plate 7 from rolling outwards when entering the interiors of the hollow covers 8.

[0035] Embodiment 5, as Figures 1 to 6 shown, this embodiment is a further improvement based on Embodiment 1, and the specific content is as follows:

[0036] On the left and right sides of the two hollow covers 8, U-shaped frames 13 are fixedly installed. Inside the four U-shaped frames 13, hollow plates 14 are slidably installed. On the left and right sides of the two rectangular hollow cylinders 9, wedge blocks 15 located inside the hollow plates 14 are fixedly installed. On the outsides of the four hollow plates 14, pull rods 16 penetrating to the outsides of the U-shaped frames 13 are fixedly installed. The pull rods 16 are slidably installed inside the U-shaped frames 13. On the inner sides of the four U-shaped frames 13, springs 17 sleeved on the outside of the pull rods 16 are fixedly installed, and the springs 17 are located on the outside of the hollow plates 14.

[0037] The hollow plate 14 is restricted outside the hollow cover 8 through the U-shaped frame 13. When the rectangular hollow cylinder 9 is inserted into the interior of the hollow cover 8, the wedge blocks 15 installed on both sides thereof are exactly caught inside the hollow plate 14. At this time, the bottom of the wedge block 15 is exactly engaged with the bottom of the inner cavity of the hollow plate 14. Therefore, the rectangular hollow cylinder 9 will not be separated from the hollow cover 8, thus achieving the effect of facilitating the installation of the rectangular hollow cylinder 9. Pulling the pull rod 16 outwards can pull the hollow plate 14 to move outwards. The outward movement of the hollow plate 14 squeezes the spring 17. At this time, the hollow plate 14 is disengaged from the wedge block 15, thus achieving the effect of facilitating the disassembly of the rectangular hollow cylinder 9. After the rectangular hollow cylinder 9 is disassembled, the spring 17 expands and can push the hollow plate 14 to reset.

[0038] Embodiment 6 is as Figures 5 to 6 shown. This embodiment is a further improvement based on Embodiment 1, and the specific content is as follows:

[0039] The inner sides of the four hollow plates 14 and one end near the bottom are all designed with bevels, and the bevel angles of the hollow plates 14 correspond to the outer inclined surfaces of the wedge blocks 15.

[0040] It is convenient for the wedge block 15 to slide upwards from the bottom of the hollow plate 14.

[0041] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limitations on the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
