Description

Technical Field

[0001] This utility model belongs to the field of civil engineering technology, and in particular relates to a foundation pit enclosure for civil engineering. Background Technology

[0002] An excavation pit is a pit dug at the foundation design location according to the base elevation and foundation plane dimensions. During the construction of civil engineering projects, in order to prevent workers from accidentally falling into the excavation pit, a fence is usually installed on the ground outside the excavation pit for protection.

[0003] Existing foundation pit enclosures are usually placed on the outside of the foundation pit in the form of guardrails. Due to the uneven ground outside the foundation pit, the guardrails will be uneven after placement, and the enclosures will tilt. When the tilt is severe, it will cause the enclosures to collapse, thus affecting the protective effect. To address this, we propose a foundation pit enclosure for civil engineering. Summary of the Invention

[0004] The purpose of this utility model is to provide a foundation pit enclosure for civil engineering. By setting a connecting component, specifically connecting several enclosure main bodies to several connecting column heads and tails, the foundation pit enclosure can be installed. Then, the worker rotates the handle to drive the threaded rod to rotate, and the connecting rod drives the base plate to move up or down, thereby adjusting the height of the base plate. By adjusting the height of the base plate, the installed enclosure can be adjusted to make the enclosure more stable and reduce the occurrence of displacement. This solves the problem of uneven ground outside the foundation pit, which causes the guardrail to be uneven after placement and the enclosure to tilt. When the tilt is serious, it can even lead to the enclosure collapsing, thus affecting the protective effect.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a foundation pit enclosure for civil engineering, comprising an enclosure body, a connecting plate, and several protective rods fixedly connected inside the connecting plate. Connecting components are provided on the left and right sides of each protective rod. Each connecting component includes a connecting column, a base plate at the bottom of each connecting column, and two inserts fixedly connected to the four outer sides of each connecting column. Limiting blocks are fixedly connected to the bottom of each insert, with the limit block's side near the connecting column fixedly connected to the surface of the connecting column. A threaded hole is provided at the top of the connecting column, and a threaded rod is threadedly connected to the top of the connecting column through the threaded hole. A handle is fixedly connected to the top of the threaded rod, and a connecting rod is fixedly connected to the bottom of the threaded rod. The bottom of the connecting rod is fixedly connected to the top of the base plate. By adjusting the height of the base plate, the installed enclosure can be adjusted to make the enclosure more stable.

[0007] Furthermore, the connecting column has a hollow cavity inside, and a stabilizing block is fixedly connected to the inner wall of the connecting column. The connecting rod passes through the stabilizing block and extends to the outside, and the connecting rod is slidably connected to the stabilizing block. The stabilizing block is used to improve the stability of the connecting rod and reduce the swaying of the stabilizing block.

[0008] Furthermore, the insert is L-shaped, and several inserts are arranged in pairs, with each pair of inserts arranged symmetrically. A connecting rod is provided on one side of each of the two connecting posts. The connecting rod is inserted into the two inserts, and after the connecting rod is inserted into the two inserts, its bottom contacts the top of the limiting block. Because the insert is L-shaped and the connecting rod is I-shaped, the connecting rod is more stable after insertion and will not fall off.

[0009] Furthermore, the protective rod has an insertion hole on the side near the connecting rod, and a square groove is formed at the top of the insertion hole. The protective rod also has grooves on the left and right sides of its top. The square groove is used to insert into the positioning block, thereby making the protective rod more stable after it is installed with the shaft.

[0010] Furthermore, several insertion shafts are fixedly connected to the side of the connecting rod near the protective rod. A positioning block is fixedly connected to the top of the insertion shaft, and a threaded knob is threadedly connected inside the positioning block. A pressing block is fixedly connected to the bottom of the threaded knob. The insertion shaft is adapted to the insertion hole, and the positioning block is adapted to the square groove at the top of the insertion hole. The protective rod is inserted into the insertion shaft through the insertion hole, and the pressing block is adapted to the groove. After the pressing block enters the groove, it can prevent the protective rod from falling off and improve the fixing effect.

[0011] This utility model has the following beneficial effects:

[0012] This utility model completes the installation of the foundation pit enclosure by setting up a connecting component, specifically by connecting several enclosure main bodies to several connecting column heads and tails. Then, the workers can rotate the handle to drive the threaded rod to rotate, and the connecting rod will drive the chassis to move up or down, thereby adjusting the height of the chassis. By adjusting the height of the chassis, the installed enclosure can be adjusted to make the enclosure more stable and reduce the occurrence of displacement.

[0013] This utility model uses insert shafts, specifically, multiple insert shafts on the connecting rod are inserted into the insertion holes on multiple protective rods. By rotating the threaded knob clockwise in sequence, the extrusion block moves downward and enters the groove, thereby pressing and fixing the protective rod and completing the connection. This method allows the connecting rod to be disassembled and replaced with protective rods of different lengths to meet different needs.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] Please see Figures 1-5As shown, this utility model is a foundation pit enclosure for civil engineering, including an enclosure body 1. The enclosure body 1 includes a connecting plate 11. Several protective rods 111 are fixedly connected inside the connecting plate 11. Connecting components 12 are provided on the left and right sides of the protective rods 111. The connecting components 12 include connecting columns 121. A base plate 122 is provided at the bottom of the connecting column 121. Two inserts 123 are fixedly connected to the four sides of the outer side of the connecting column 121. Limiting blocks 124 are fixedly connected to the bottom of the inserts 123. The side of the limiting block 124 near the connecting column 121 is fixedly connected to the surface of the connecting column 121. A threaded hole is opened at the top of the connecting column 121. A threaded rod 125 is threadedly connected to the top of the connecting column 121 through the threaded hole. A handle 251 is fixedly connected to the top of the threaded rod 125. A connecting rod 252 is fixedly connected to the bottom of the threaded rod 125. The bottom of the connecting rod 252 is fixedly connected to the top of the base plate 122.

[0025] The connecting column 121 has a hollow cavity inside. A stabilizing block 253 is fixedly connected to the inner wall of the connecting column 121. The connecting rod 252 passes through the stabilizing block 253 and extends to the outside. The connecting rod 252 is slidably connected to the stabilizing block 253.

[0026] The insert 123 is L-shaped, and several inserts 123 are arranged in pairs. The two inserts 123 in each pair are arranged symmetrically. A connecting rod 112 is provided on one side of each of the two connecting posts 121. The connecting rod 112 is inserted into the two inserts 123. After the connecting rod 112 is inserted into the two inserts 123, its bottom contacts the top of the limiting block 124.

[0027] The protective rod 111 has a socket 113 on the side near the connecting rod 112. The top of the socket 113 has a square groove. The left and right sides of the top of the protective rod 111 have grooves 114.

[0028] Several insert shafts 13 are fixedly connected to the side of the connecting rod 112 near the protective rod 111. A positioning block 131 is fixedly connected to the top of the insert shaft 13. A threaded knob 132 is threadedly connected inside the positioning block 131. A pressing block 133 is fixedly connected to the bottom of the threaded knob 132. The insert shaft 13 is adapted to the insertion hole 113.

The pressing block 133 is adapted to the groove 114.

[0029] One specific application of this embodiment is:

[0030] In use, the connecting rod 112 is inserted into the insertion hole 113 on the protective rod 111 via the insertion shaft 13, and the positioning block 131 is also inserted into the square groove on the insertion hole 113. When multiple insertion shafts 13 are inserted into multiple protective rods 111 simultaneously, the threaded knob 132 is rotated clockwise to move the pressing block 133 downward, causing the pressing block 133 to enter the groove 114, thereby pressing and fixing the protective rod 111. At this time, the connecting rod 112 is installed on the protective rod 111. When it is necessary to disassemble the connecting rod 112, the threaded knob 132 is rotated counterclockwise to make the pressing block 133 leave the groove 114, releasing the fixing of the connecting rod 112. Then, the connecting rod 112 can be pulled out for disassembly, which facilitates the selection of different lengths of protective rods 111 according to the size of the pit. After the connecting rod 112 is connected to the protective rod 111, the connecting post 121 is placed on the pit, and then the connecting rod 112 is inserted. Insert the two inserts 123 and make the bottom of the connecting rod 112 contact the top of the limiting block 124 to complete the docking of the protective rod 111 and the connecting column 121. This method can quickly complete the docking work and is more efficient. At the same time, the connecting column 121 is provided with two inserts 123 on each of its four sides, which can connect the main body 1 of the enclosure in different directions. After connecting several main bodies 1 of the enclosure to several connecting columns 121 end to end, the installation of the foundation pit enclosure can be completed. After installation, the workers can rotate the handle 251 to drive the threaded rod 125 to rotate. The threaded rod 125 will drive the chassis 122 to move up or down through the connecting rod 252, thereby adjusting the height of the chassis 122. The stabilizing block 253 is used to limit the movement of the connecting rod 252, making the movement of the connecting rod 252 more stable. By adjusting the height of the chassis 122, the installed enclosure can be adjusted to make the enclosure more stable and reduce the occurrence of displacement.
