Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit support, and particularly relates to a foundation pit support device for avoiding displacement. Background Art

[0002] A foundation pit is an earth pit excavated at the designed position of the foundation according to the base elevation and the foundation plane size. For a relatively deep foundation pit or a foundation pit adjacent to a building, a foundation pit support device can be used to support the foundation pit. During support, it is necessary to provide bracing, reinforcement and corresponding protection measures for the side wall of the foundation pit and the surrounding environment;

[0003] When most foundation pit support devices support the side wall of the foundation pit, they can only provide single support for the side wall of the foundation pit through a support plate. If the support force is insufficient, it is easy to cause the support plate to displace, thus affecting the overall support effect and causing great inconvenience. Content of the Utility Model

[0004] Therefore, the utility model provides a foundation pit support device for avoiding displacement to solve the above problems in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] According to the first aspect of the utility model, a foundation pit support device for avoiding displacement includes a support plate, a first upper reinforcement rod and a second upper reinforcement rod. A first positioning block is fixedly installed at the outer wall end of the support plate, and a reinforcement plate is arranged outside the first positioning block. The reinforcement plate and the first positioning block are both penetrated by a second bolt;

[0007] The first upper reinforcement rod is fixedly installed at the outer side end of the reinforcement plate through a screw. A second positioning block is fixedly installed on the outer surface of the support plate, and an adapter frame located outside the support plate is connected to the outside of the second positioning block. A first lower reinforcement rod is fixedly installed on the outside of the adapter frame through a screw;

[0008] The second upper reinforcement rod is fixedly installed at the outer side end of the first upper reinforcement rod.

[0009] Further, the first positioning block and the reinforcement plate are connected in a plug-in manner, and the longitudinal section of the first positioning block is an "L" - shaped structure.

[0010] Further, the upper end of the reinforcement plate extends to the outer side end of the support plate, and a first bolt is penetrated through the upper end of the reinforcement plate.

[0011] Further, one end of the second upper reinforcement rod far from the first upper reinforcement rod is connected to the reinforcement plate through a screw.

[0012] Further, the connection frame and the second positioning block are connected in a sliding manner and fixed by screws.

[0013] Further, the first upper reinforcement rod and the first lower reinforcement rod are arranged in a staggered manner, and the height of the first lower reinforcement rod is lower than that of the first upper reinforcement rod.

[0014] Further, a second lower reinforcement rod connected to the connection frame is installed in the middle of the outer side of the first lower reinforcement rod.

[0015] The utility model has the following advantages:

[0016] 1. Through the reinforcement plate and the second bolt, the second bolt fixes the position of the support plate. At the same time, the upper end of the reinforcement plate extends to the outer end of the support plate. The reinforcement plate limits the support plate without affecting the support of the foundation pit by the support plate, avoiding the phenomenon of displacement of the support plate.

[0017] 2. Through the first upper reinforcement rod and the first lower reinforcement rod, the first upper reinforcement rod and the first lower reinforcement rod are arranged in a staggered manner, and the height of the first lower reinforcement rod is lower than that of the first upper reinforcement rod. It is convenient to support the upper end and the lower end of the support plate by the first upper reinforcement rod and the first lower reinforcement rod respectively, so that the supporting force is evenly distributed and the overall supporting effect is improved.

[0018] 3. Through the second upper reinforcement rod and the second lower reinforcement rod, the second upper reinforcement rod is fixedly installed between the reinforcement plate and the first upper reinforcement rod by screws, and the second lower reinforcement rod is fixedly installed between the connection frame and the first lower reinforcement rod, so as to facilitate the all-round support of the foundation pit under the combined action of the first upper reinforcement rod and the first lower reinforcement rod.

The first positioning block 2 and the second positioning block 7 are arranged alternately, which is convenient for subsequent better positioning and installation of a reinforcement plate 3 and a connecting frame 8 respectively. During installation, first place the support plate 1 in the foundation pit so that the support plate 1 is tightly connected to the side wall of the foundation pit. A reinforcement plate 3 is arranged outside the first positioning block 2. Second bolts 5 are respectively penetrated through the reinforcement plate 3 and the first positioning block 2. The first positioning block 2 and the reinforcement plate 3 are connected in a plug-in manner, and the longitudinal section of the first positioning block 2 is an "L" - shaped structure. Insert the reinforcement plate 3 at the outer end of the first positioning block 2 and move it to the lowermost end, and then sequentially rotate and insert the second bolts 5 into the reinforcement plate 3, the first positioning block 2 and the support plate 1, and at the same time insert them into the foundation pit, which is convenient for fixing the positions of the support plate 1 and the reinforcement plate 3 and reinforcing the support plate 1.

[0025] The upper end of the reinforcement plate 3 extends to the outer end of the support plate 1, and a first bolt 4 is penetrated through the upper end of the reinforcement plate 3. After being fixed, the upper end of the reinforcement plate 3 contacts the upper ends of the support plate 1 and the foundation pit and is fixed by the first bolt 4. At this time, the reinforcement plate 3 limits the support plate 1 while not affecting the support of the foundation pit by the support plate 1, avoiding the phenomenon of displacement of the support plate 1. A first upper reinforcement rod 6 is fixedly installed at the outer end of the reinforcement plate 3 by screws, which is convenient for supporting the upper end of the support plate 1 through the first upper reinforcement rod 6.

Moreover, a first lower reinforcing rod 9 is fixedly installed on the outside of the adapter frame 8 through screws. Insert the adapter frame 8 into the outer end of the second positioning block 7 and move it to the lowermost end, and then fix the adapter frame 8 through screws, so as to facilitate the support of the lower end of the support plate 1 by the first lower reinforcing rod 9. The first upper reinforcing rod 6 and the first lower reinforcing rod 9 are arranged in a staggered manner, and the height of the first lower reinforcing rod 9 is lower than that of the first upper reinforcing rod 6, which is convenient for the first upper reinforcing rod 6 and the first lower reinforcing rod 9 to support the upper end and the lower end of the support plate 1 respectively, so that the supporting force is evenly distributed and the overall supporting effect is improved;

[0027] A second upper reinforcing rod 10 is fixedly installed at the outer end of the first upper reinforcing rod 6. One end of the second upper reinforcing rod 10 away from the first upper reinforcing rod 6 is connected to the reinforcing plate 3 through screws. A second lower reinforcing rod 11 connected to the adapter frame 8 is installed in the middle of the outside of the first lower reinforcing rod 9.
