Description

Technical Field

[0001] This utility model relates to the field of building construction safety protection technology, and more specifically, to a remote anti-wall collapse support frame. Background Technology

[0002] In building construction, it is often necessary to excavate beneath existing walls, such as to excavate ventilation shafts or pipe trenches. This type of work creates small pits about 1 to 2 meters deep, causing the base of the wall to be suspended in the air and lose lateral soil support, making it prone to instability and collapse, seriously threatening the lives of workers inside the pit.

[0003] Traditional support methods typically involve directly constructing brick piers or driving in wooden wedges and steel pipes for support at the base of the wall. However, in situations where the foundation pit space is limited, the working surface is restricted, or continuous operation is required, construction workers cannot enter the foundation pit or carry out effective direct reinforcement work at the base of the wall, making traditional methods impractical. Therefore, there is an urgent need for a device that can be installed from a safe working surface away from the wall and can provide effective and reliable support to the wall. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1-6 As shown, this embodiment provides a remote anti-collapse wall support frame, including a support assembly, a grid assembly, and a buffer assembly 11 located between the grid assembly and the outer wall of the wall 1. The support assembly, as the main load-bearing structure of the entire support frame, includes at least two parallel support units. Each support unit includes an inclined main support beam 2 and a vertically arranged support leg 3. The main support beams 2 in adjacent support units are connected by a transverse connector 4. The grid assembly includes transverse steel pipes 5 and vertical steel pipes 6 overlapped by fasteners. The vertical steel pipe 6 is connected to one end of the main support beam 2.

[0034] In the support assembly of this embodiment, the main support beam 2 includes a first connecting plate 21 and a second connecting plate 22 fixedly connected to both ends. The first connecting plate 21 is used to connect the vertical steel pipe 6, and the second connecting plate 22 is used to fix the platform on the side of the wall 1. Specifically, the first connecting plate 21 is rectangular and is fixedly connected to the vertical steel pipe by welding. The second connecting plate 22 is rectangular, with through holes at its four corners, through which expansion bolts are passed and fixed to a stable existing building structure away from the wall, such as a ground, floor slab, beam, or column.

[0035] The support leg 3 is vertically arranged, and its upper end is fixedly connected to the lower end face of the main support beam 2 by welding. The bottom end of the support leg 3 is provided with a third connecting plate 31, which is rectangular in shape and has through holes at its four corners. Expansion bolts are passed through and fixed to the platform on the side of the wall 1, such as existing building structures such as ground, floor slab, beam, or column. A transverse connector 4 is arranged between the main support beams 2 of two adjacent support units, and the two ends of the transverse connector 4 are fixedly connected to the two adjacent main support beams 2 respectively.

[0036] In this embodiment, the main supporting beam 2, supporting legs 3, and transverse connecting parts 4 are all made of I-beams. In practical applications, channel steel or seamless steel pipes can also be used. By welding multiple transverse connecting parts 4 together, a rigid spatial frame with good overall integrity is formed, which can enhance the lateral stability and torsional resistance of the support frame itself.

[0037] In this embodiment, the intersecting horizontal steel pipes 5 and vertical steel pipes 6 are connected by right-angle fasteners 7, forming an alternating horizontal and vertical grid-like support structure. The grid assembly is a surface-mounted support structure that faces the wall and transmits pressure. Multiple horizontal steel pipes 5 and vertical steel pipes 6 are overlapped by right-angle fasteners to form a dense grid-like structure, the total area of ​​which is greater than or equal to the area of ​​the outer wall of the wall to be supported. The vertical steel pipes 6 in the grid assembly are fixedly connected to the top of the supporting main beam 2 by welding.

[0038] To further enhance the deformation resistance of the grid assembly and prevent it from bending and becoming unstable under pressure, diagonal steel pipes 8 are also provided at the top and bottom transverse steel pipes of the grid assembly. One end of the diagonal steel pipe 8 is welded to the grid assembly, and the other end is connected to the supporting main beam 2, forming a stable triangular support structure together with the supporting main beam 2.

[0039] Specifically, the two ends of the inclined steel pipe 8 are connected to the transverse steel pipe 5 and the supporting main beam 2, respectively. Specifically, a connecting steel pipe 9 is fixed to the upper end of the supporting main beam 2. One end of the inclined steel pipe 8 is connected to the connecting steel pipe 9 through a swivel coupler 10, and the other end is connected to one of the transverse steel pipes 5 through a swivel coupler 10.

[0040] More specifically, at least two oblique steel pipes 8 are arranged to connect to the connecting steel pipe 9; at least one oblique steel pipe 8 is connected to the upper transverse steel pipe 5; and at least one oblique steel pipe 8 is connected to the lower transverse steel pipe 5. In this embodiment, two oblique steel pipes 8 are connected to the same connecting steel pipe 9, respectively located on both sides of the supporting main beam 2, one obliquely upward and the other obliquely downward.

[0041] In this embodiment, the buffer assembly 11 is located between the grid assembly and the outer wall of the wall 1. Specifically, the buffer assembly 11 is made of foam board, such as polystyrene foam board, and is placed between the grid assembly and the wall 1 to fill and seal it. As a buffering medium, the buffer assembly 11 can protect the surface of the wall 1; by filling the gap between the grid assembly 1 and the wall 1, the buffer assembly 11 can also prevent the falling of gravel and soil to a certain extent.

[0042] The remote wall collapse prevention support frame provided in this embodiment is installed on a remote stable structure on one side of the wall 1, such as a stable existing building structure away from the wall, such as the ground, floor slab, beam, or column.

[0043] For example, the remote anti-collapse support frame provided in this embodiment is installed on the basement roof slab, with a newly excavated ventilation shaft foundation pit about 2 meters deep below the wall 1.

[0044] First, assemble the support components. Select channel steel as the main support beam 2 and support legs 3. After determining the support positions, drill holes in the stable structure using an electric drill, and fix the third connecting plate 31 of the support leg 3 to the stable structure using expansion bolts 3. Weld the main support beam 2 to the top of the support leg 3, extending it towards the wall 1. Fix the second connecting plate 22 of the main support beam 2 to the stable structure using expansion bolts. Connect the main support beams 2 of adjacent support units by welding using transverse connectors to form a stable overall frame structure.

[0045] Next, the grid assembly is constructed. A grid-like surface is formed in front of the extended end of the supporting main beam 2 using φ48mm steel pipes and right-angle fasteners 7. The middle of the vertical steel pipes 8 of the grid assembly is welded and fixed to the supporting main beam 2. Then, at the upper and lower edges of the grid assembly, i.e., at the uppermost and lowermost horizontal steel pipes 5, diagonal steel pipes 8 are connected respectively. The other end of the diagonal steel pipes 8 is connected to the supporting main beam 2, forming a reliable triangular support.

[0046] Finally, fill the buffer assembly 11. Cut the polystyrene foam board commonly used on the construction site into appropriate sizes and tightly insert it into the gap between the erected grid assembly and the surface of the wall 1. The foam board can fill all the gaps between the grid assembly and the wall 1, or it can be filled in the gaps corresponding to the vertical steel pipes. Ensure that the filling is tight and use its elastic deformation to play a buffering and pressure equalization role.

[0047] After installation, this support frame provides support to the wall 1 through the support components, the grid components composed of steel pipes, and the buffer components 11 formed by foam boards. This effectively prevents the risk of wall collapse after excavation, ensures the safety of construction personnel, and solves the technical problem of providing long-distance, large-area, flexible safety support when the foundation pit space is small, the working surface is limited, or continuous operation is required, and when it is not possible to work directly at the base of the wall 1.

[0048] The remote anti-collapse support frame provided in this embodiment uses standard steel profiles and steel pipes as its main components, which are connected by bolts and welding. It is easy to install and disassemble and has a high reusability. The buffer layer uses foam board commonly found on site, which is easy to process and install.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
