Description

Technical Field

[0001] This utility model relates to the field of foundation pit support technology, and in particular to a novel foundation pit support structure. Background Technology

[0002] Foundation pit support is a temporary protective project, so easy assembly and disassembly of the foundation pit support structure can effectively improve construction efficiency.

[0003] A support device for municipal foundation pit construction disclosed in Chinese patent CN222730573U includes a support rod comprising a threaded sleeve and a screw. By rotating the threaded sleeve, the screw extends and retracts within the sleeve, thus adjusting the length of the support rod. This allows it to be used to tighten two support plates with different spacings. However, while solving the problem, this support device for municipal foundation pit construction has the following drawbacks:

[0004] When installing the support rod, if the length of the support rod differs significantly from the width of the support plates on both sides of the pit, adjusting the length of the support rod requires rotating the threaded sleeve many times. However, there are no good power tools to operate the rotation of the threaded sleeve, which makes the length adjustment process of the support rod very time-consuming and labor-intensive, seriously affecting the assembly efficiency of the support structure. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0006] Therefore, one objective of this utility model is to propose a novel foundation pit support structure, which aims to solve the problem that the adjustment process of the support rod length of the support device used in municipal foundation pit construction is time-consuming and labor-intensive, affecting the assembly efficiency of the support structure.

[0007] To achieve the above objectives, one embodiment of the present invention provides a novel foundation pit support structure, including a support plate, a sleeve, a telescopic rod, a limiting component, and a screw. The telescopic rod is slidably inserted into the inside of the sleeve, and the limiting component is sleeved on the outer surface of the telescopic rod, with one side of the limiting component abutting against one end of the sleeve.

[0008] The limiting component includes two semi-circular sleeves hinged together. The inner wall of the semi-circular sleeves is fixedly connected with multiple retaining rings, and the outer surface of the telescopic rod is provided with multiple retaining grooves that are adapted to the retaining rings.

[0009] The screw is slidably inserted into the inside of the telescopic rod, and the outer surface of the screw is threaded with a limit nut;

[0010] Both the sleeve and the screw are fitted with supports at their ends.

[0011] The beneficial effects are as follows: When installing the support structure between two support plates, the length of the support structure of the support plate can be coarsely adjusted by quickly sliding the telescopic rod inside the sleeve. After the coarse adjustment, the limiting component is locked on the outer surface of the telescopic rod, preventing the telescopic rod from being inserted further into the sleeve. Finally, the limiting nut is rotated to tighten it against one end of the telescopic rod, thereby finely adjusting the support structure of the support plate. Through these two steps of coarse and fine adjustment, the support structure can be quickly assembled. Therefore, the adjustment of the support structure saves time and effort and speeds up the assembly efficiency of the support structure.

[0012] Preferably, one side of the support plate is fixedly connected to a limiting groove, and the side of the limiting groove is provided with multiple through holes. One side of the support is provided with a positioning hole. One end of the sleeve is fixedly connected to a connector head one, and the sleeve is hinged to the inside of the support through the connector head one. One end of the screw is fixedly connected to a connector head two, and the screw is hinged to the inside of the support through the connector head two.

[0013] The beneficial effects are:

[0014] Firstly, when installing the support structure, the two supports at the ends of the sleeve and the screw can be positioned in the limiting grooves on the two side support plates by means of the pin. Then, the telescopic rod is inserted into the sleeve, and the telescopic rod and the screw are lifted by both hands respectively. By sliding the telescopic rod in the sleeve, the telescopic rod and the screw are inserted together. Finally, the limiting component is installed, and the limiting nut is rotated to fix the length of the support structure. This can be operated independently by one person, thus saving labor costs.

[0015] Secondly, the sleeve and screw are hinged to the support. Therefore, if there is a certain height difference between the two support plates on both sides, after positioning the two supports at the ends of the sleeve and screw in the limiting grooves on the two support plates, when inserting the telescopic rod and screw, the sleeve and screw can be moved within the two supports to ensure that the telescopic rod and screw can be smoothly inserted, thereby improving practicality.

[0016] Preferably, one side of the semicircular sleeve is inlaid with a magnetic block.

[0017] The beneficial effects are as follows: after the two semicircular sleeves are locked onto the surface of the telescopic rod, the magnetic blocks inside the semicircular sleeves are magnetically connected, thereby easily and quickly fixing the two semicircular sleeves together, avoiding the problem of the two semicircular sleeves opening up during the support process, which would cause the limiting components to fall off, thus improving stability.

[0018] Preferably, in any of the above solutions, a limiting cylinder is fixedly connected to the outer surface of one end of the sleeve, and the outer surface of the limiting cylinder is provided with a notch.

[0019] The beneficial effects are as follows: After the support structure is installed, the limiting component will be inserted into the inside of the limiting cylinder, and the limiting cylinder will limit the limiting component, so that the two semi-circular sleeves will not open, thereby further improving the stability of the limiting component.

[0020] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] This utility model provides a novel foundation pit support structure.

[0031] Example 1:

[0032] like Figure 1 As shown, it includes a support plate 1, a sleeve 2, a telescopic rod 3, a limiting component 4, and a screw 5. The telescopic rod 3 is slidably inserted into the inside of the sleeve 2. By inserting and removing the telescopic rod 3 inside the sleeve 2, the total length of the sleeve 2 and the telescopic rod 3 can be quickly adjusted. The limiting component 4 is sleeved on the outer surface of the telescopic rod 3. The limiting component 4 limits the telescopic rod 3. When one side of the limiting component 4 abuts against one end of the sleeve 2, the telescopic rod 3 cannot continue to be inserted into the sleeve 2, thereby limiting the minimum total length of the sleeve 2 and the telescopic rod 3.

[0033] like Figure 3 As shown, the limiting component 4 includes two semi-circular sleeves 41 hinged together. Multiple retaining rings 42 are fixedly connected to the inner wall of the semi-circular sleeves 41. Multiple slots 31 that are adapted to the retaining rings 42 are opened on the outer surface of the telescopic rod 3. When the two semi-circular sleeves 41 are rotated together, the retaining rings 42 are inserted into the slots 31. A magnetic block 43 is embedded on one side of the semi-circular sleeves 41, so that the two semi-circular sleeves 41 will not open and will not fall off the surface of the telescopic rod 3. Thus, the limiting component 4 cannot slide on the surface of the telescopic rod 3. Therefore, when the telescopic rod 3 is inserted into the sleeve 2 and one side of the semi-circular sleeve 41 abuts against one end of the sleeve 2, the telescopic rod 3 cannot continue to be inserted into the sleeve 2, thus achieving the purpose of limiting the telescopic rod 3.

[0034] like Figure 1 , Figure 3 and Figure 4 As shown, the telescopic rod 3 has a hollow structure, and the screw 5 is slidably inserted into the inside of the telescopic rod 3. By inserting and removing the screw 5 inside the telescopic rod 3, the total length of the telescopic rod 3 and the screw 5 can be adjusted. Furthermore, the outer surface of the screw 5 is threaded with a limit nut 51. Figure 1 As shown, when the limiting nut 51 is rotated and pressed against one end of the telescopic rod 3, the screw 5 can be limited, preventing it from being inserted further into the telescopic rod 3.

[0035] like Figure 1As shown, supports 6 are installed at the ends of both the sleeve 2 and the screw 5, increasing the contact area between the ends of the sleeve 2 and the screw 5 and the support plate 1, thereby improving the stability of the support.

[0036] The working principle of this embodiment is as follows: When in use, support plates 1 are erected on both sides of the foundation pit, and then a support structure is assembled between the two support plates 1, that is, the telescopic rod 3 is inserted into the sleeve 2, and then the screw 5 is inserted into the telescopic rod 3, and then the support 6 at the end of the sleeve 2 is pressed against the inner side of one of the support plates 1.

[0037] One operator holds the sleeve 2 while another operator pulls the telescopic rod 3 outward from inside the sleeve 2, so that the support 6 at the end of the screw 5 abuts against the inner side of another support plate 1. At this time, the limiting component 4 is locked on the outer surface of the telescopic rod 3, and it is ensured that the limiting component 4 is locked in the slot 31 closest to the end of the sleeve 2.

[0038] Finally, rotate the limiting nut 51 so that it rests against the end of the telescopic rod 3 and pushes the telescopic rod 3 to slide into the sleeve 2, so that the limiting component 4 abuts against the end of the sleeve 2, thereby limiting the minimum length of the sleeve 2, the telescopic rod 3 and the screw 5, while the support plates 1 on both sides limit the maximum length of the sleeve 2, the telescopic rod 3 and the screw 5. Therefore, the sleeve 2, the telescopic rod 3 and the screw 5 can provide stable support for the support plates 1 on both sides.

[0039] Example 2:

[0040] like Figure 1 , Figure 2 and Figure 4 As shown, based on Embodiment 1, a limiting groove 11 is fixedly connected to one side of the support plate 1, and the support 6 can be inserted into the inside of the limiting groove 11. A plurality of through holes 12 are provided on the side of the limiting groove 11, and a positioning hole 61 is provided on one side of the support 6. By using a pin to pass through the through hole 12 and the positioning hole 61, the support 6 can be positioned inside the limiting groove 11.

[0041] like Figure 2 and Figure 4 As shown, one end of the sleeve 2 is fixedly connected to a connector 21. The sleeve 2 is hinged inside the support 6 through the connector 21, and the sleeve 2 can move relative to the support 6. One end of the screw 5 is fixedly connected to a connector 52. The screw 5 is hinged inside the support 6 through the connector 51, and the screw 5 can move relative to the support 6. If there is a certain height difference between the two support plates 1 on both sides, after positioning the two supports 6 at the ends of the sleeve 2 and the screw 5 in the limiting grooves 11 on the two support plates 1 on both sides, when the telescopic rod 3 and the screw 5 are inserted, the sleeve 2 and the screw 5 can be moved within the two supports 6 to ensure that the telescopic rod 3 and the screw 5 can be inserted smoothly.

[0042] The working principle of this embodiment is as follows: When in use, support plates 1 are erected on both sides of the foundation pit. Then, the support 6 at the end of the sleeve 2 and the screw 5 is positioned in the limiting groove 11 on the support plates 1 on both sides by passing through the pin through the through hole 12 and the positioning hole 61, thereby installing the sleeve 2 and the screw 5 on the support plates 1 on both sides.

[0043] Insert the telescopic rod 3 into the sleeve 2, and then the operator lifts the ends of the telescopic rod 3 and the screw 5 with both hands respectively. By sliding the telescopic rod 3 inside the sleeve 2, the screw 5 is inserted into the telescopic rod 3. At this time, the sleeve 2, the telescopic rod 3 and the screw 5 can be placed horizontally between the two support plates 1.

[0044] Finally, the limiting component 4 is snapped onto the surface of the telescopic rod 3, and then the limiting nut 51 is rotated to tighten it against one end of the telescopic rod 3. In this embodiment, the installation of the support structure can be carried out independently by one person.

[0045] Example 3:

[0046] like Figure 5 As shown, based on Embodiment 1 or Embodiment 2, a limiting cylinder 22 is fixedly connected to the outer surface of one end of the sleeve 2. After the limiting component 4 is locked onto the surface of the telescopic rod 3, the telescopic rod 3 is inserted into the inside of the sleeve 2. After the limiting component 4 is inserted into the inside of the limiting cylinder 22, the limiting cylinder 22 can limit each of the semicircular sleeves 41 of the limiting component 4, so that they will not open under external force, thereby ensuring that the limiting component 4 will not fall off during the support process, further improving the stability of the structure. In addition, the outer surface of the limiting cylinder 22 is provided with a notch 23, which is reserved for the hinge part of the two semicircular sleeves 41, so that the limiting component 4 can be smoothly inserted into the inside of the limiting cylinder 22.
