Description

Technical Field

[0001] This utility model relates to the field of pile foundation support technology, specifically to a support device for pile foundation construction. Background Technology

[0002] Pile foundation support refers to using pile foundations as part of the support structure. Through reasonable arrangement and construction, it aims to stabilize the foundation and protect surrounding buildings and the environment. Pile foundation support usually includes components such as piles, pile caps, and support plates, which together form a stable support system. There are various types of pile foundation support, and steel plate support is one of the more common support methods.

[0003] During the construction of steel plate support, the prepared steel plates are inserted into the soil in an alternating manner, and the interlocking joints of two adjacent steel plates can be connected. During the excavation of the foundation pit, if the foundation pit is deep or the geological conditions are poor, additional crossbeams are needed to enhance stability. Most of these crossbeams are connected to the support steel plates by welding or bolts to form a stable support system.

[0004] However, in the existing technology, the support steel plates and beams are mostly connected by welding or bolts. Although the connection effect is good, both welding and multiple bolt connections are very troublesome to operate and are prone to damage to the steel plates. At the same time, the stress point of the welded or bolted support steel plates is singular, resulting in poor overall support stability. Therefore, we propose a support device for pile foundation construction. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a support device for pile foundation construction, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example 1:

[0030] Reference Figure 1-5 This is the first embodiment of the present utility model, which discloses a support device for pile foundation construction, including a first steel plate 1, a second steel plate 2 on both the left and right sides of the first steel plate 1, a connecting mechanism 3 on the outer side of the second steel plate, the same crossbeam 4 on the inner side of the two sets of connecting mechanisms 3, and a reinforcement mechanism 5 on the outer side of the first steel plate 1.

[0031] The first steel plate 1 has locking slot 1 on both the left and right sides, and the second steel plate 2 has locking slot 2 on both the left and right sides. The two second steel plates 2 are interlocked with the locking slot 1 of the first steel plate 1 through the corresponding locking slot 2, forming a continuous support wall that can support the soil and prevent soil displacement or collapse, thereby ensuring the safety of the foundation pit excavation and surrounding buildings.

[0032] The connecting mechanism 3 includes a mounting plate 303, which is disposed on the outside of the second steel plate 2. A hook-shaped strip 302 is fixedly connected to the top of the mounting plate 303, and the hook of the hook-shaped strip 302 hooks onto the top of the second steel plate 2. An open box 307 is fixedly connected to the side of the mounting plate 303 away from the second steel plate 2. An L-shaped block 304 is fixedly connected to the outside of the second steel plate 2. Under the action of the L-shaped block 304, the mounting plate 303 is limited from the bottom, which increases the stress points on the first steel plate 1 and the second steel plate 2 after the crossbeam 4 is installed, and improves the overall service life of the support device.

[0033] The top and front of the open box 307 are open, and the crossbeam 4 is inserted through the opening of the open box 307, which is convenient and quick to operate and greatly improves the installation efficiency of the crossbeam 4.

[0034] Specifically, a fixing rod 305 is fixedly connected to the top of the second steel plate 2, and a stop block 301 is movably connected to the top of the fixing rod 305. A damping is provided at the connection between the fixing rod 305 and the stop block 301 to ensure that the stop block 301 can rotate but cannot rotate automatically. A slot 308 is provided at the bottom of the open box 307, and an insert block 309 is fixedly connected to the bottom of the crossbeam 4. The bottom of the insert block 309 passes through the slot 308 and extends to the outside of the open box 307. Under the action of the slot 308 and the insert block 309, the movement direction of the crossbeam 4 inside the open box 307 is limited.

[0035] Before installing the crossbeam 4, the stop block 301 is passed through the rectangular groove 306. The mounting plate 303 is placed in front of the first steel plate 1 and the second steel plate 2 using the hook strip, and the mounting plate 303 is inserted into the corresponding L-shaped block 304. Then, the stop block 301 is rotated 90 degrees to limit it from the top of the hook strip, thus completing the installation of the mounting plate 303. After the mounting plate 303 is installed, both ends of the crossbeam 4 are placed into the corresponding open boxes 307, and the insert block 309 is inserted into the slot 308, thus completing the initial installation of the crossbeam 4. Under the action of the crossbeam 4 and the mounting plate 303, the support wall composed of the first steel plate 1 and the second steel plate 2 on both sides is limited to ensure that it will not shift to the middle and cause the collapse of the foundation pit, thus ensuring the safety of the pile foundation construction process.

[0036] Example 2:

[0037] Reference Figure 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0038] The reinforcement mechanism 5 includes a fixing block 501, which is fixedly connected to the outside of the first steel plate 1. A diagonal rod 505 is provided on the outside of the fixing block 501, and a rectangular hole is provided at the top of the diagonal rod 505.

[0039] Specifically, a T-shaped groove 502 is provided on the outer side of the fixing block 501, and a T-shaped block 503 is fixedly connected to the outer side of the diagonal rod 505. The outer side of the T-shaped block 503 is adapted to the inner side of the T-shaped groove 502. After the T-shaped block 503 enters the T-shaped groove 502, the connection between the fixing block 501 and the diagonal rod 505 is completed, so that the diagonal rod 505 is placed at an angle on the outer side of the first steel plate 1, and the rectangular hole is located below the rectangular block 504 at the bottom of the crossbeam 4. A rectangular block 504 is fixedly connected to the bottom of the crossbeam 4, and the bottom of the rectangular block 504 extends into the inner side of the rectangular hole. Under the action of the rectangular block 504 and the rectangular hole, the diagonal rod 505 is aligned and limited from the top, ensuring the stability of the diagonal rod 505 installation and improving the overall support effect in actual use.

[0040] Before installing the crossbeam 4, align the T-shaped block 503 at one end of the diagonal bar 505 with the T-shaped groove 502 on the outside of the fixing block 501 to complete the initial installation of the diagonal bar 505. When installing the crossbeam 4, insert the rectangular block 504 at the bottom of the crossbeam 4 into the rectangular hole at the top of the diagonal bar 505 to complete the overall installation of the support device. Under the action of the crossbeam 4, the support walls on both sides are supported. The combination of the crossbeam 4 and the steel plate support can form a stable support system, improving the overall rigidity and load-bearing capacity of the support structure.

[0041] The remaining structure is the same as that in Example 1.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
