Description

Technical Field

[0001] This utility model relates to the field of foundation pit support replacement technology, and in particular to a construction structure for support replacement using the main structure of a building. Background Technology

[0002] In foundation pit engineering, the replacement of supports involves taking certain technical measures under specific conditions to gradually replace the internal support structure system that plays a temporary supporting role, thereby ensuring that the construction can continue safely and smoothly after the temporary internal support is removed. Its essence is the safe and orderly adjustment, transfer and redistribution of stress.

[0003] During the replacement of supports, diagonal bracing is often used to connect the support piles and the basement structure to control deformation and achieve stress transfer. However, due to the short distance between the support piles and the wall and the small construction space, the construction efficiency is reduced. Furthermore, the diagonal bracing often needs to pass through the wall and connect to the corbel on the surface of the basement floor, which increases the difficulty of waterproofing inside the basement.

[0004] Therefore, it is necessary to provide a new construction structure that utilizes the building's main structure for support replacement to solve the above problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a structural replacement construction structure for the main structure of a building that can accelerate the construction efficiency of the replacement support.

[0006] To solve the above-mentioned technical problems, the present invention provides a construction structure for replacing supports using the main structure of a building, comprising: a support beam, the two ends of which are respectively connected to the foundation pit protection pile and the main building structure; multiple embedded rods are installed inside both the support beam and the foundation pit protection pile; the interior of each embedded rod is rotatably connected to a connecting cylinder, and the interior of the connecting cylinder is threadedly connected to a first screw and a second screw; the first screw is engaged and rotatably connected to the interior of a fixed cylinder, and the interior of the fixed cylinder is slidably connected to a piston and a support rod, and the second screw is threadedly connected to the support rod.

[0007] Preferably, the main building structure consists of concrete support columns and cast-in-place floor slabs, and the side walls of the concrete support columns are connected to the cast-in-place floor slabs.

[0008] Preferably, a reinforcing cage is provided inside the supporting beam, the reinforcing cage connects the reinforcing bars inside the cast-in-place floor slab and the foundation pit protection pile, and the supporting beam and the cast-in-place floor slab are cast simultaneously.

[0009] Preferably, corbels are installed on the sidewalls of the concrete support column, and the surfaces of the corbels are connected to the support beams.

[0010] Preferably, one side of the embedded rod connected to the foundation pit protection pile is connected to the inside of the connecting cylinder connected to it, which is connected to the first screw; the other side of the embedded rod connected to the support beam is connected to the inside of the connecting cylinder connected to it, which is connected to the second screw.

[0011] Preferably, a connecting pipe is installed at the top of the fixed cylinder, and a valve is installed on the side wall of the connecting pipe.

[0012] Preferably, one end of the support rod is fitted with a rib, and the rib is distributed in a ring on the surface of the support rod.

[0013] Compared with related technologies, the construction structure for replacing the main structure of a building provided by this utility model has the following beneficial effects:

[0014] This utility model provides a construction structure utilizing the main structure of a building for support. During the construction of the main building, when the cast-in-place floor slab needs to be poured, the supporting beam is simultaneously poured. The supporting beam connects the foundation pit protection pile to the cast-in-place floor slab, allowing the main building to support the foundation pit protection pile. After the cast-in-place floor slab is completed, no other support method is needed to support the foundation pit protection pile, thus accelerating construction efficiency. After the cast-in-place beam solidifies, embedded rods are installed on the side walls of both the cast-in-place beam and the foundation pit protection pile. The side walls of the embedded rods are rotatably connected to the connecting cylinder. Inside the connecting cylinder, the first screw and the second screw are rotated respectively, causing the supporting rod and the fixing cylinder to be tilted at the position between the supporting beam and the foundation pit protection pile. Water is injected into the fixed cylinder through the connecting pipe between the foundation pit protection piles, filling the space between the piston and the fixed cylinder. The connecting pipe is then closed. The support rod rotates on the side wall of the second screw, causing the support rod to move the piston towards the inside of the fixed cylinder. This causes the piston to squeeze the water inside the fixed cylinder, which in turn squeezes the fixed cylinder and the support rod. This, in turn, causes the fixed cylinder and the support rod to squeeze the foundation pit protection piles and the support beam. The fixed cylinder and the support rod are firmly and stably fixed at the connection point between the foundation pit protection piles and the support beam, increasing the stability and strength of the connection. This facilitates the support beam providing support for the foundation pit protection piles and makes it easier to remove the supports inside the foundation pit later. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1 to 3 , Figure 1 A schematic diagram of a preferred embodiment of the building main structure replacement and support construction structure provided by this utility model; Figure 2 for Figure 1 The diagram shows an enlarged view of the structure at point A. Figure 3 for Figure 2The diagram shows the internal structure of the fixed cylinder. The structure utilizing the building's main structure for support replacement includes: a supporting beam 2, with its two ends connected to the foundation pit protection piles 1 and the building main body 3, respectively; multiple embedded rods 13 are installed inside both the supporting beam 2 and the foundation pit protection piles 1; a connecting cylinder 5 is rotatably connected inside the embedded rods 13; the connecting cylinder 5 is threadedly connected to a first screw 9 and a second screw 10; the first screw 9 is engaged and rotatably connected to the inside of the fixed cylinder 7; a piston 12 and a support rod 6 are slidably connected inside the fixed cylinder 7; and the second screw 10 is threadedly connected to the support rod 6. The main building 3 consists of concrete support columns 31 and cast-in-place floor slabs 32, with the sidewalls of the concrete support columns 31 connected to the cast-in-place floor slabs 32. During the construction of the main building 3, when the cast-in-place floor slabs 32 need to be poured, the support beams 2 are poured simultaneously. The support beams 2 connect the foundation pit protection piles 1 to the cast-in-place floor slabs 32, allowing the main building 3 to support the foundation pit protection piles 1. After the construction of the cast-in-place floor slabs 32 is completed, there is no need to use other support methods to support the foundation pit protection piles 1 when the foundation pit support is removed, thus accelerating construction efficiency. After the cast-in-place beams 2 solidify, the embedded rods 13 are installed on the sidewalls of both the cast-in-place beams 2 and the foundation pit protection piles 1. The sidewalls of the embedded rods 13 are rotatably connected to the connecting cylinder 5. Inside the connecting cylinder 5, the first screw 9 and the second screw 10 are rotated respectively, so that the support rods 6 and the solidified... The fixed cylinder 7 is inclined between the supporting beam 2 and the foundation pit protection pile 1. Water is injected into the fixed cylinder 7 through the connecting pipe 8, filling the space between the piston 12 and the fixed cylinder 7. Then, the connecting pipe 8 is closed. The supporting rod 6 is rotated on the side wall of the second screw 10. The supporting rod 6 drives the piston 12 to move towards the inside of the fixed cylinder 7, causing the piston 12 to squeeze the water inside the fixed cylinder 7. The water in turn squeezes the fixed cylinder 7 and the supporting rod 6, causing the fixed cylinder 7 and the supporting rod 6 to squeeze the foundation pit protection pile 1 and the supporting beam 2 in the opposite direction. The fixed cylinder and the supporting rod 6 are firmly and stably fixed at the connection between the foundation pit protection pile 1 and the supporting beam 2, increasing the stability and firmness of the connection between the foundation pit protection pile 1 and the supporting beam 2. This facilitates the supporting beam 2 to provide support for the foundation pit protection pile 1 and makes it easier to remove the support inside the foundation pit later.

[0021] The supporting beam 2 is equipped with a steel cage 21 inside. The steel cage 21 connects the steel bars inside the cast-in-place floor slab 32 and the foundation pit protection pile 1. The supporting beam 2 and the cast-in-place floor slab 32 are cast at the same time to facilitate the stability and firmness of the connection between the supporting beam 2, the cast-in-place floor slab 32 and the foundation pit protection pile 1.

[0022] The side wall of the concrete support column 31 is fitted with a corbel 4, and the surface of the corbel 4 is connected to the support beam 2. In order to facilitate the corbel 4 to provide support to the support beam 2, the pressure transmitted from the foundation pit protection pile 1 is transmitted to the concrete support column 31 through the support beam 4, so that the concrete support column 31 provides support to the foundation pit protection pile 1 and increases the stability of the foundation pit protection pile 1.

[0023] One side of the embedded rod 13 connected to the foundation pit protection pile 1 is connected to the interior of the connecting cylinder 5, which is connected to the first screw 9; the other side of the embedded rod 13 connected to the support beam 2 is connected to the interior of the connecting cylinder 5, which is connected to the second screw 10. In order to facilitate the first screw 9 and the second screw 10 to tilt and fix the fixing cylinder 7 and the support rod 6 between the support beam 2 and the foundation pit protection pile 1, the fixing cylinder 7 and the support rod 6 provide support for the foundation pit protection pile 1.

[0024] A connecting pipe 8 is installed at the top of the fixed cylinder 7, and a valve is installed on the side wall of the connecting pipe 8 to facilitate the injection of water into the fixed cylinder 7 and to seal the connecting pipe 8 through the valve to prevent water from leaking from the inside of the fixed cylinder 7.

[0025] One end of the support rod 6 is fitted with a rib 11, and the rib 11 is distributed in a ring on the surface of the support rod 6. When the support rod 6 is rotated, the rib 11 increases the friction at the bottom of the support rod 6, making it easier for people to rotate the support rod 6.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
