Description

Technical Field

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

[0002] Excavation pit support is a set of measures used to support, reinforce, and protect the sidewalls and surrounding environment of an excavation pit, ensuring the safety of underground structure construction and the surrounding environment. The main purpose of excavation pit support is to maintain the stability of buildings and the natural ground outside the pit, preventing soil instability and collapse. Excavation pit support typically involves assembling multiple support plates to form a wall-like structure.

[0003] The drawback of existing technology is that foundation pit support usually uses bolted connections. Not only are the support panels bolted together, but the reinforcing structure and base of the support panels are also bolted, resulting in high cost and long time consumption for the construction of foundation pit support. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a combined foundation pit support panel to improve the installation efficiency of foundation pit support devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A composite foundation pit support panel includes a panel body and a support base. A reinforcing structure is provided between the panel body and the support base. The cross-sectional shape of the panel body is an arc shape with the center protruding outward. One lateral end of the panel body is provided with an outward-opening hook portion, and the other lateral end of the panel body is provided with an inner hook portion that can cooperate with the outer hook portion of another panel body. The inner hook portion and the outer hook portion are longitudinally slidably connected. The support base is provided with a connecting portion to complete the fixed connection of adjacent support bases through the connecting portion after the inner hook portion and the outer hook portion slide into place.

[0007] The modular foundation pit support panels are used to assemble and form a foundation pit support structure. The main body of the panel supports the sidewalls of the foundation pit. The side of the panel that abuts against the sidewall is the outer side of the panel, and the side facing the support base is the inner side. Inner and outer hooks are provided at both ends of the main body of the panel. The inner and outer hooks cooperate to allow adjacent panels to be assembled only by longitudinal sliding. After the two panels are assembled, they are fixedly connected to the adjacent support bases through connecting parts, thus completing the assembly of the support panels with high efficiency. The cross-sectional shape of the main body of the panel is an outwardly convex arc. When the soil pressure increases, the arc structure can undergo a certain degree of elastic deformation. When the arc of the main body of the panel decreases, there is a mutual outward pushing force between the inner and outer hooks, making the connection between adjacent panels tighter and significantly improving the foundation pit support structure's ability to withstand soil pressure.

[0008] Preferably, one side of the support base corresponds to the inner side of the inner hook to form a neck. This further improves the anti-detachment capability after the adjacent panel main bodies are assembled, and enhances the overall structural compactness after the adjacent panel main bodies and adjacent support bases are installed.

[0009] Preferably, the connecting part is a screw hole, and the connecting parts of adjacent support seats are fixedly connected with locking rods by mating bolts, so as to achieve reliable locking of adjacent support seats.

[0010] Preferably, a reinforcing plate is provided on the inner side of the top of the main body of the enclosure. This strengthens the top of the enclosure and enhances its ability to withstand soil pressure.

[0011] Preferably, the lower end of the support base is provided with a column, and the lower end of the column is provided with a cone. The column, together with the cone, can be inserted into the bottom of the foundation pit for positioning, ensuring the reliability of the support base in the foundation pit and improving the support capacity of the support structure.

[0012] Preferably, the reinforcing plate has insertion holes for matching inserts, and the support base has connecting through holes. The modular foundation pit support panels can be used in combination to accommodate different foundation pit heights. During use, the inserts of the upper support panel can be inserted into the insertion holes of the reinforcing plate of the lower support panel. Simultaneously, connecting rods can be inserted into the connecting through holes in the support bases of the two aligned support panels for positioning, enabling the combined application of support panels in foundation pits of different heights.

[0013] Preferably, the reinforcing structure consists of inclined plates that are fixedly connected to the main body of the enclosure and the support base at both ends. The inclined plates strengthen the overall structure of the enclosure and the support base, improving the overall strength of the enclosure. The reinforcing plates strengthen the top of the enclosure, the inclined plates strengthen the middle of the enclosure, and the support base strengthens the bottom of the enclosure, resulting in a high overall structural strength of the enclosure.

[0014] Preferably, the support base, the main body of the enclosure, the reinforcing structure, and the reinforcing plate are integrated into a single structure. This facilitates molding and eliminates the need for on-site connection of the support base, the main body of the enclosure, the reinforcing structure, and the reinforcing plate, reducing on-site work time and intensity. Furthermore, the integrated structure ensures accurate positioning of each component, facilitating the assembly and installation of the support enclosure. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0021] In the description of this utility model, it should be understood that the technical features defined by terms such as "first" and "second" which have a sequential concept are only for the purpose of clearly describing the defined technical features and making the defined technical features clearly distinguishable from other technical features, and do not represent that they are named in this way in actual implementation. Therefore, they should not be construed as limitations on this utility model.

[0022] Example 1,

[0023] A type of composite foundation pit support panel, such as Figures 1 to 4 As shown, it includes a panel body 1 and a support base 5. A reinforcing structure 8 is provided between the panel body 1 and the support base 5. The cross-sectional shape of the panel body 1 is an arc shape with the center protruding outward. One lateral end of the panel body 1 is provided with an outwardly opening hook 2. The other lateral end of the panel body 1 is provided with an inner hook 3 that can cooperate with the outer hook 2 of another panel body 1. The inner hook 3 and the outer hook 2 are longitudinally slidably connected. The support base 5 is provided with a connecting part 6 so that after the inner hook 3 and the outer hook 2 slide into place, the adjacent support bases 5 are fixedly connected through the connecting part 6.

[0024] The modular foundation pit support panel is used to assemble and form a foundation pit support structure. The main body 1 of the panel supports the sidewall of the foundation pit. The side of the main body 1 that abuts against the sidewall of the foundation pit is the outer side of the main body 1, and the side of the main body 1 facing the support base 5 is the inner side of the main body 1. The support base 5 can be fixed to the bottom of the foundation pit to support the bottom of the main body 1.

[0025] The inner hook 3 and the outer hook 2 are respectively provided at the two transverse ends of the main body 1 of the enclosure. The inner hook 3 and the outer hook 2 cooperate to allow the two adjacent enclosure main bodies 1 to be assembled only by longitudinal sliding. After the two enclosure main bodies 1 are combined, the two adjacent support seats 5 are fixedly connected by the connecting part 6, thus completing the assembly of the support enclosure. The assembly efficiency is high.

[0026] The cross-sectional shape of the main body 1 of the enclosure is an outwardly convex arc. When the soil pressure increases, the arc structure can undergo a certain degree of elastic deformation. When the arc of the main body 1 of the enclosure decreases, there is a mutual outward pushing force between the inner hook part 3 and the outer hook part 2, which makes the connection between adjacent enclosure bodies 1 tighter and greatly improves the ability of the foundation pit support structure to cope with soil pressure.

[0027] In such Figure 1 In the illustrated scheme, the inner shape of both the outer hook 2 and the inner hook 3 is "S" shaped. When they fit together, and the inner hook 3 and outer hook 2 are longitudinally slidably assembled, they cannot be directly separated from their openings, ensuring the reliability of their longitudinal sliding. In other embodiments of this scheme, when the inner sides of the outer hook 2 and inner hook 3 are fitted with shapes that cannot form an anti-detachment structure, fastening structures such as bolts or clips can be added to further enhance the reliability of the locking of the inner hook 3 and outer hook 2.

[0028] Example 2,

[0029] A type of composite foundation pit support panel, such as Figures 1 to 4 As shown, the structure includes a main body 1 and a support base 5. A reinforcing structure 8 is provided between the main body 1 and the support base 5. The reinforcing structure 8 consists of inclined plates that are fixedly connected to the main body 1 and the support base 5 at both ends. The inclined plates strengthen the overall structure of the main body 1 and the support base 5, improving the overall strength of the support enclosure. The main body 1 has a cross-sectional shape that is an arc shape with the center protruding outwards. One lateral end of the main body 1 has an outwardly opening hook 2, and the other lateral end of the main body 1 has an inner hook 3 that can cooperate with the outer hook 2 of another main body 1. The inner hook 3 and the outer hook 2 are longitudinally slidably connected. The support base 5 has a connecting part 6 to complete the fixed connection of adjacent support bases 5 after the inner hook 3 and the outer hook 2 slide into place. One side of the support base 5 corresponds to the inner side of the inner hook 3 to cooperate with the inner hook 3 to form a neck 4. Figure 4As shown, the connecting part 6 is a screw hole, and the connecting parts 6 of adjacent support seats 5 are fixedly connected to locking rods 7 by fitting bolts. This achieves reliable locking of adjacent support seats 5. A reinforcing plate 9 is provided on the inner side of the top of the main body 1 of the enclosure. The reinforcing plate 9 is a flat plate structure, which strengthens and improves the strength of the top of the main body 1 of the enclosure, making the top of the main body 1 of the enclosure strong in resisting soil pressure. The support seat 5, the main body 1 of the enclosure, the reinforcing structure 8, and the reinforcing plate 9 are an integral structure. There is no need to assemble and connect the support seat 5, the main body 1 of the enclosure, the reinforcing structure 8, and the reinforcing plate 9 on site, reducing the time and intensity of on-site operations. At the same time, the four are integrated into one structure, and their respective positional accuracy is easily guaranteed, which facilitates the combination and installation of the support enclosure.

[0030] The lower end of the support base 5 is provided with a post 11, and the lower end of the post 11 is provided with a cone 12. The reinforcing plate 9 is provided with a hole 10 that matches the post 11, and the support base 5 is provided with a connecting through hole 13. The post 11 and the cone 12 can be inserted into the bottom of the foundation pit for positioning, ensuring the reliability of the support base 5 in the foundation pit and improving the support capacity of the support structure. The combined foundation pit support panels can be used in combination to accommodate different foundation pit heights. When in use, the post 11 of the upper support panel can be inserted into the hole 10 of the reinforcing plate 9 of the lower support panel. At the same time, the connecting through holes 13 in the support bases 5 of the two aligned support panels can be used to insert connecting rods for positioning, realizing the combined application of support panels in foundation pits of different heights.

[0031] The reinforcing plate 9 strengthens the top of the main body 1 of the enclosure, the inclined plate strengthens the middle of the main body 1 of the enclosure, and the support base 5 strengthens the bottom of the main body 1 of the enclosure. The overall structural strength of the main body 1 of the enclosure is relatively high.
