Description

Technical Field

[0001] This invention relates to the field of deep foundation pit construction technology for bridge main piers, specifically to a prefabricated corbel stiffening support structure and its construction method. Background Technology

[0002] To ensure the safety of construction and the surrounding environment of deep foundation pits for bridge piers, subway stations, and high-rise buildings, it is necessary to adopt support, reinforcement, and protection measures for the pit sidewalls and surrounding environment. Since most deep foundation pit projects for bridge piers, subway stations, and high-rise buildings are excavated in urban areas, and important structures often exist around the pits, prefabricated corbel stiffened support structures are widely used to ensure the safety of the surrounding environment and to save construction time and costs.

[0003] In existing technologies, such as the "Steel Structure Bracket and Steel Structure Support Structure" with Chinese Patent No. CN106836480B, a sleeve body is included, which is composed of two or more sleeves; each sleeve has a sleeve wall, and the sleeve wall forms a sleeve cavity; the sleeve body is provided with a first through hole, which may or may not penetrate the sleeve body in a direction perpendicular to the length direction of the sleeve body. Compared with the bracket structure in the prior art, the bracket structure of the present invention can save more than 50% of the steel used. Moreover, the bracket structure of the present invention can be processed into standard parts in a factory workshop and then assembled with columns or beams on the construction site, resulting in a shorter on-site construction time, saving at least 60% of the on-site construction time.

[0004] In the existing technology, although the existing corbel support structure provides the function of supporting structural components, the installation of the corbel support structure is basically carried out by conventional welding methods. Welding installation is prone to cracking of the weld seam after long-term support, affecting the supporting force. In addition, it cannot be disassembled and disassembled. Direct cutting and disassembly will make it unusable. To address the above problems, a prefabricated corbel stiffening support structure and its construction method are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a prefabricated corbel stiffening support structure and its construction method, so as to solve the problems mentioned in the background art, where the corbel support structure is installed by welding, which is not convenient for later disassembly and reuse, and the weld seam cracks after long-term gravity support, affecting safety.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated corbel reinforcement support structure, comprising a column, a corbel assembly disposed in the middle of the column, a fastening assembly disposed at the bottom of the corbel assembly, a bottom support assembly installed at the bottom of the column, an annular groove formed on the outer wall of the middle portion of the column, an assembly ring disposed on the outer side of the corbel assembly, an assembly slide plate fixedly installed at the bottom of the assembly ring, multiple assembly slide rails evenly distributed around the outer wall of the column, the assembly slide plate being slidably connected to the assembly slide rails, multiple corbel support frames disposed around the outer wall of the assembly ring, a vertical plate fixedly installed on the inner side of the corbel support frame, multiple horizontal plates evenly distributed on the inner side of the vertical plate, a reinforcing plate fixedly installed between two adjacent horizontal plates, a side support block installed on the top of the vertical plate, and a bottom support plate fixedly installed at the bottom of the vertical plate. An annular groove is formed on the outer wall of the middle portion of the column shell to engage the assembly ring. Inside the annular groove, assembly slides and assembly rails are distributed around the bottom of the assembly ring for sliding assembly connection. The assembly ring and assembly slides are made of die-cast material, while the column shell and assembly rails are cast, which facilitates assembly connection and improves the strength of the structural components. The bracket support frame and the assembly ring are die-cast, and a vertical plate is connected to the inside of the bracket support frame. The vertical plate is supported by a horizontal plate and a reinforcing plate, which improves the lateral support force of the bracket support frame. The side support block is supported on the top of the inside of the bracket support frame, and the bottom support plate is connected and supported at the bottom of the bracket support frame, thereby improving the overall support force and ensuring that the bracket support structure can provide long-term stable support. The bracket support structure adopts a prefabricated connection method, which can improve the convenience of installation and disassembly. Moreover, the one-piece cast prefabricated structure can ensure long-term stable use and facilitates disassembly and recycling, reducing material waste.

[0007] A fastening ring is provided on the outer side of the fastening assembly. The fastening ring is sleeved on the outer side of the upright plate. Multiple fastening seats are evenly distributed on the inner side of the fastening ring. Limiting plates are evenly fixedly installed on the inner wall of the fastening ring.

At the same time, the limiting plates and limiting blocks are snapped into the inner side of the upright plate to achieve a limiting connection. Thus, the fastening ring can provide a fastening support installation effect for the upright plate and the assembly ring, further ensuring the stability of the bracket support structure during assembly and connection, and facilitating the improvement of structural safety through further reinforcement.

[0008] Preferably, the bottom of the base support assembly is fixedly mounted on a chassis, and the top of the chassis has multiple fixing holes evenly distributed around its circumference. A base support ring is installed on the top of the chassis. The multiple fixing holes on the chassis facilitate the use of bolts to pass through the fixing holes, providing stable ground pile support for the column at the bottom.

[0010] Preferably, multiple bottom mounting blocks are evenly distributed on the top of the bottom support ring, and a clamping ring is fixedly installed on the top of each bottom mounting block. The bottom support side plates are all connected through the clamping ring. One side of the bottom mounting block is pressed against the outer side of the bottom of the column, the top is connected to the clamping ring, and the bottom is supported on the top of the bottom support ring. Thus, through multi-directional support and in conjunction with the clamping ring, it is pulled to the bottom support side plate, which is conducive to the stable use of the column and bracket assembly.

[0011] Preferably, the outer side of the column is provided with a column shell, and the inner side of the column is provided with intersecting inner support plates. The inner support plates are connected to the sides of the inner support plates with inner support rings. The inner support rings are vertically distributed inside the column. The column shell can provide the main body for installation. The inner support plates can ensure support inside the column while reducing the structural weight and improving the efficiency of transportation. The inner support rings can provide traction support for the inner support plates, thereby ensuring the overall support performance.

[0012] Preferably, a first annular gasket is fitted inside the assembly ring, and a second annular gasket is fitted inside the first annular gasket. The inner wall of the second annular gasket is fitted onto the outer wall of the annular groove. The first and second annular gaskets can provide support for the assembly ring on the inner wall, which facilitates the installation of the assembly ring by raising it, while ensuring a tight connection between the annular groove and the assembly ring.

[0013] Preferably, an assembly pad is fixedly installed on the top of the bracket support frame, and multiple assembly holes are evenly opened through both sides of the bottom of the assembly pad.

The top of the side support block is on the inner top of the bracket support frame. One end of the diagonal braces and the side support bar is supported on the side of the bracket support frame and the inner side of the vertical plate. Thus, through multiple supports and the upper triangular structure design, the support strength of the bracket support structure is guaranteed.

[0015] Preferably, a bottom support strip is installed at the bottom of the bottom support plate, one end of which is connected to the bottom side wall of the bracket support frame. A reinforcing plate is installed at the bottom of the bottom support strip, and two limiting seats are fixedly installed on the side of the reinforcing plate. The sides of the limiting seats are fixedly installed on the bottom of one side of the bracket support frame. A fixing plate is fixedly installed at the bottom of the bracket support frame, and the side of the fixing plate is connected to the side of the mounting plate. The plate extends and supports the bottom of the bottom support plate, and is supported by the reinforcing plate. It is fixed to the bottom of one end of the bracket support frame by connecting the limiting seats, thus achieving a multi-level support effect, further improving the support strength, and ensuring long-term stable support.

[0016] Preferably, the inner wall of the fastening seat is provided with anti-slip strips, the top of the fastening seat is equipped with an upper cover, the bottom of the fastening seat is equipped with a lower support plate, the bottom of the lower support plate is equipped with a lower support rib, and the lower support plate and the lower support plate are connected through the side. The lower support plate and the lower support rib are both connected to the outer wall of the column shell. The anti-slip strips provide greater friction between the fastening seat and the contact surface of the column shell. The upper cover and the lower support plate are respectively limited at the upper and lower ends of the fastening seat to ensure the positioning and fastening effect, avoiding easy displacement under external force. The lower support plate and the connecting rib can further provide support at the bottom, thereby ensuring the stable positioning and limiting effect of the lower support plate. This is conducive to multiple guarantees of positioning and fastening, and improves safety.

[0017] A construction method for a prefabricated corbel stiffening support structure includes the following steps:

[0018] S1. Firstly, the main body can be installed through the column shell. The inner support plate can ensure support inside the column while reducing the structural weight and improving the efficiency of transportation.

The horizontal plate and the reinforcing plate support the inner side of the vertical plate to improve the lateral support force of the bracket support frame. The side support block supports the top of the inner side of the bracket support frame. The bottom support plate is connected and supported at the bottom of the bracket support frame, thereby improving the overall support force and ensuring that the bracket support structure can provide long-term stable support.

[0021] S4. At the same time, the bracket support structure adopts a prefabricated connection method, which can improve the convenience of installation and disassembly. Furthermore, the one-piece cast prefabricated structure can ensure long-term stable use and facilitates later disassembly and recycling.

[0022] S5. The first and second annular gaskets provide support for the assembly ring on the inner wall, which facilitates the installation of the assembly ring by providing a raised position, while ensuring a tight connection between the annular groove and the assembly ring.

[0023] S6. The fastening ring is fitted onto the outside of the upright plate, and multiple fastening seats are installed on the inner wall of the fastening ring to support the outer wall of the column shell. At the same time, the limiting piece and the limiting block are inserted into the inner side of the upright plate to achieve a limiting connection. Thus, the fastening ring can provide a fastening support for the upright plate and the assembly ring, further ensuring the stability of the corbel support structure during assembly and connection, and helping to improve the structural safety through further reinforcement.

[0024] S7. The anti-slip strip provides greater friction between the fastening seat and the column housing. The upper cover and lower support plate, which are respectively positioned at the upper and lower ends of the fastening seat, ensure the positioning and fastening effect and prevent easy displacement under external force.

[0025] S8. The chassis has multiple fixing holes, which facilitate the use of bolts to pass through the fixing holes and provide stable ground support for the column at the bottom.

One side of the bottom block is pressed against the outer perimeter of the bottom of the column, the top is connected to the clamping ring, and the bottom is supported on the top of the bottom support ring. Thus, through multi-directional support, and with the clamping ring pulling on the bottom support side plates, it is conducive to the stable use of the column and bracket assembly.

The upper cover and lower support plate are respectively limited at the upper and lower ends of the fastening seat to ensure the positioning and fastening effect, avoiding easy displacement under external force. The lower support plate and connecting ribs can further provide support at the bottom, thereby ensuring the stable limiting effect of the lower support plate. This is conducive to multiple guarantees of limiting and fastening, and is conducive to improving structural safety through further reinforcement.

[0030] 3. In this invention, a bottom support assembly is provided, and multiple fixing holes are opened on the chassis. This facilitates the use of bolts to pass through the fixing holes, providing stable ground pile support for the column at the bottom. The bottom support ring can be snapped into the bottom of the column shell, which facilitates insertion and improves the ease of installation. The bottom support side plates are evenly distributed and support the bottom of the column.
