Description

A foundation pit support device

Technical Field

The utility model relates to the field of foundation pit construction equipment, in particular to a foundation pit supporting device.

Background technique

The building foundation usually needs to be excavated deeper, and the inside of the foundation pit may collapse due to the influence of groundwater or rain, so the support structure of the foundation pit is indispensable. The existing foundation pit protection method usually includes the following steps: first, place a suitable baffle on the side wall of the foundation pit, then install a base at the bottom of the foundation pit through pins, etc. After the base is completed, a support rod is set between the base and the baffle to support the baffle, thereby preventing the collapse of the side wall of the foundation pit. For example, the Chinese patent with patent publication number CN219386335U discloses a foundation pit support frame, and its use principle is roughly the same as the above principle. Although it realizes the support of the foundation pit, in actual use, the inclined support rod will cause greater interference to the construction of the foundation pit.

Detailed ways

In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

Example 1

As shown in Fig. 1-4, this embodiment provides a foundation pit support device, which includes at least one set of baffles 110 and a support mechanism disposed between the at least one set of baffles 110, the support mechanism includes at least four threaded rods 120, sleeves 130 are slidably disposed at both ends of the threaded rods 120 along the length direction thereof, baffle blind holes 210 are disposed at the edges of the baffles 110, and handles 220 are disposed at the end surfaces of the baffle blind holes 210 on the baffles 110. A connector 410 is provided at the sleeve 130 to be clearance-matched with the baffle blind holes 210; an adjusting nut 140 for adjusting the position of the sleeve 130 is provided at the threaded rod 120.

When in use, first place the baffle 110 on the two side walls of the foundation pit, then place the threaded rod 120 between the two baffles 110, rotate the adjusting nut 140 so that the connecting head 410 at the sleeve 130 extends into the baffle 110, and support the baffle 110 through the threaded rod 120 and the sleeve 130, thereby completing the support of the side walls of the foundation pit.

The foundation pit support device in this embodiment supports the baffle plate 110 by providing a support mechanism at the edge of the baffle plate 110, which not only realizes the support of the side wall of the foundation pit, but also, compared with the common foundation pit support devices currently, the support mechanism will not interfere with the construction of the workers at the bottom of the foundation pit, thereby facilitating the smooth progress of the foundation pit construction. After the construction is completed, the adjustment nut 140 is loosened, and then the connector 410 is pulled out from the blind hole 210 of the baffle plate to complete the disassembly of the foundation pit support device, thereby facilitating the installation and disassembly of the foundation pit support device by the workers.

3 and 4 , the inner wall of the baffle blind hole 210 expands to one side to form a strip groove 310, the end of the connector 410 is provided with a protrusion 420 that fits with the strip groove 310 in a clearance, and the bottom end of the baffle blind hole 210 expands outward to form a limiting groove 320, and the end of the protrusion 420 can extend into the limiting groove 320 and rotate in the limiting groove 320.

In this embodiment, by providing the limiting groove 320 and the protrusion 420, during construction, after the connecting head 410 is inserted into the baffle blind hole 210, the sleeve can be rotated to cause the protrusion 420 and the strip groove 310 to be misaligned, thereby preventing the connecting head 410 from being detached from the baffle blind hole 210, thereby further improving the stability of the foundation pit support device during use.

In this embodiment, the number of the baffle blind holes 210 on the baffle 110 is twice the number of the threaded rods 120 in the support mechanism, and two adjacent baffle blind holes 210 are spaced apart along the height direction of the baffle 110 .

By setting the number and positions of the baffle blind holes 210, it is possible to arrange four baffles in the foundation pit.

As shown in FIG. 4 , the sleeve 130 is provided with a strip-shaped through hole 430 arranged along the axial direction thereof, and the end of the threaded rod 120 is provided with a limit block 440 extending into the strip-shaped through hole 430 .

In this embodiment, by providing the limit block 440 and the strip-shaped through hole 430 , it is possible to prevent the sleeve 130 from falling off the threaded rod 120 when the threaded rod 120 is moved, thereby better improving the safety of the foundation pit supporting device during use.

The specific working principle of the foundation pit supporting device in this embodiment is as follows:

When in use, the staff first places the two baffles 110 on the side wall of the foundation pit, then moves the threaded rod 120 between the two baffles 110, then moves the sleeve 130 so that the connector 410 at the sleeve 130 extends into the blind hole 210 of the baffle, then rotates the sleeve 130 so that the protrusion 420 and the strip groove 310 are misaligned; after the threaded rod 120 is installed, the adjustment thread 420 on the threaded rod 120 is rotated so that the sleeve moves toward the end of the baffle, thereby supporting the baffle 110 through the threaded rod 120 and the sleeve 130, that is, completing the support for the side wall of the foundation pit. When disassembling, first loosen the adjustment nut 420, then rotate the sleeve 130, and when the protrusion 420 at the sleeve is rotated to be opposite to the strip groove 310, the connector 410 is pulled out from the blind hole 210 of the baffle to complete the disassembly of the foundation pit support device.

In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
