The existing technology often involves setting a supporting plate between the upper and lower beams, and then using supporting steel pipes to support the upper and lower supporting plates to form a supporting structure. However, this supporting structure only relies on the supporting steel pipe in the middle to unload the load of the column to be replaced. Its stability is poor, which can easily lead to low overall safety performance of the column replacement project, and further improvements are needed. Utility Model Content

A first support structure and a second support structure are respectively provided on both sides of the column to be supported. Both the first support structure and the second support structure include a support steel pipe. The support steel pipe is filled with high-strength grout. A first support plate is provided at the upper end of the support steel pipe, and a second support plate is provided at the lower end of the support steel pipe. A first steel wedge and a second steel wedge are also provided above the first support plate, and the first steel wedge and the second steel wedge press against each other.

[0006] Optionally, it also includes chemical anchors, through which the second support plate is fixedly connected to the building component.

[0007] Optionally, a first upper auxiliary support device and a second upper auxiliary support device are respectively provided on the upper two sides of the supporting steel pipe, and the first upper auxiliary support device and the second upper auxiliary support device are symmetrically distributed.

[0008] Optionally, the first upper auxiliary support device and the second upper auxiliary support device are arranged at an angle.

The first connecting steel pipe is fixedly connected to the building component, and the second connecting steel pipe is fixedly connected to the support steel pipe.

[0010] Optionally, one end of the jack is connected to the first connecting steel pipe through a sleeve joint, and the other end of the jack is fixedly connected to the second connecting steel pipe through a connecting plate.

[0011] Optionally, a first lower auxiliary support device and a second lower auxiliary support device are respectively provided on both sides of the lower part of the supporting steel pipe.

[0012] Beneficial effects: Compared with the prior art, this utility model is a column replacement support structure for building engineering, including building components and columns to be supported on the building components. The columns to be supported are provided with a first support structure and a second support structure on both sides. This utility model increases the strength and support force of the supporting steel pipe by injecting high-strength grout into the inside of the supporting steel pipe. On the other hand, steel wedges are used at the top of the supporting steel pipe to squeeze each other and buffer the contact between the supporting steel pipe and the building components, so that the supporting steel pipe and the building components are always stably connected, thereby improving the safety of the overall column replacement project.

Detailed Implementation

[0020] The following is in conjunction with the appendix Figures 1 to 5 This utility model will be described in detail.

[0021] This utility model relates to a column replacement support structure for building engineering, comprising a building component 1 and a column 2 to be supported and replaced, disposed on the building component 1. A first support structure 3 and a second support structure 4 are respectively provided on both sides of the column 2. Both the first support structure 3 and the second support structure 4 include a supporting steel pipe 31. The supporting steel pipe 31 is filled with high-strength grout 32. A first support plate 33 is provided at the upper end of the supporting steel pipe 31, and a second support plate 34 is provided at the lower end. A first steel wedge 35 and a second steel wedge 36 are also provided above the first support plate 33, and the first steel wedge 35 and the second steel wedge 36 press against each other. This utility model, by injecting high-strength grout 32 into the supporting steel pipe 31, increases the strength and supporting force of the supporting steel pipe 31. Furthermore, the use of steel wedges at the top of the supporting steel pipe 31 to press against each other buffers the contact between the supporting steel pipe 31 and the building component 1, ensuring a stable connection between the supporting steel pipe 31 and the building component 1, thereby improving the overall safety of the column replacement project.

[0022] Preferably, chemical anchors 5 are also included, through which the second support plate 34 is fixedly connected to the building component 1. Chemical anchors 5 are more robust than ordinary bolt connections, making the installation of the support steel pipe 31 more stable.

[0023] To further improve the technical solution, a first upper auxiliary support device 6 and a second upper auxiliary support device 7 are respectively provided on the upper two sides of the supporting steel pipe 31. The first upper auxiliary support device 6 and the second upper auxiliary support device 7 are symmetrically distributed to help improve the support strength of the supporting steel pipe 31, thereby better unloading the load of the column 2 that needs to be supported.

[0024] Preferably, the first upper auxiliary support device 6 and the second upper auxiliary support device 7 are arranged at an angle to expand the support range of the support steel pipe 31.

[0025] In this technical solution, the first upper auxiliary support device 6 and the second upper auxiliary support device 7 both include a first connecting steel pipe 61, a jack 62 and a second connecting steel pipe 63 connected in sequence. The first connecting steel pipe 61 is fixedly connected to the building component 1 and the second connecting steel pipe 63 is fixedly connected to the supporting steel pipe 31.

[0026] Preferably, one end of the jack 62 is connected to the first connecting steel pipe 61 via a sleeve connector 621. The sleeve connector 621 is a high-strength type. After the sleeve connector 621 is installed on the jack 62, the top end of the jack 62 is coaxially aligned with the first connecting pipe, allowing for better transmission of the supporting force of the jack 62. The other end of the jack 62 is fixedly connected to the second connecting steel pipe 63 via a connecting plate 622. The connecting plate 622 increases the contact area between the second connecting pipe and the jack 62, thus making the installation of the jack 62 more secure.

[0027] To further enhance the overall support strength of the support structure, a first lower auxiliary support device 8 and a second lower auxiliary support device 9 are respectively provided on both sides of the lower part of the support steel pipe 31. The structure of the lower auxiliary support device is the same as that of the upper auxiliary support device.
