[0002] At present, a deep foundation pit of a cut-and-cover structure (such as a subway and a high-speed railway) is mostly in the form of a combination of an underground continuous wall and an inner support foundation pit enclosure. In order to ensure the safety of the foundation pit, a steel bracing is needed to be arranged in the structure after the completion of the bottom plate and part of the side wall of the structure. The steel bracing is removed after the completion of the structure, and the process is relatively complicated and repetitive.

DETAILED DESCRIPTION

[0029] The following will be described in detail in combination with the accompanying Figures 1-4 The present application will be further described in detail.

[0030] The embodiment of the present application discloses a steel support changing and embedding device, which will be described in detail with reference to the accompanying Figure 1 and 2The pre-embedded device comprises a steel support 1 arranged in a structural side wall, a support base 2, a connector 4 and a connecting piece. The connector 4 is pre-embedded in the structural side wall. The support base 2 is connected with the connector 4 through the connecting piece. The steel support 1 is arranged on the support base 2. The support base 2 is further fixedly connected with a lateral support base 3. The lateral support base 3 abuts against both sides of the steel support 1.

[0031] With reference to Figure 1 and 2 The support base 2 comprises a support plate 22 and a connecting plate 21. The support plate 22 and the connecting plate 21 are connected with perpendicular plate surfaces. The support plate 22 and the connecting plate 21 are welded and fixed. The connecting plate 21 is provided with a connecting hole. The connecting piece is a connecting bolt. The connecting bolt is threadedly connected with the connector 4 through the connecting hole.

[0032] With reference to Figure 2 and 3 The connector 4 comprises a main body 41 and an adjusting piece. The main body 41 comprises a first end surface 413 and a second end surface 414. The first end surface 413 is arranged perpendicularly relative to the outer wall of the main body 41. The second end surface 414 is arranged obliquely relative to the outer wall of the main body 41. The adjusting piece comprises an adjusting end portion 42 and an adjusting connecting portion 43. The adjusting end portion 42 is rotationally connected to the second end surface 414. The adjusting connecting portion 43 is fixedly connected to one end of the adjusting end portion 42 away from the rotation axis. The adjusting connecting portion 43 is made of a flexible material. The adjusting connecting portion 43 can resist a part of displacement of the adjusting end portion 42 generated in the process of rotation adjustment by means of elastic deformation. The main body 41 is provided with a moving groove 411 and a positioning hole 412. The moving groove 411 is arranged along the axial direction of the main body 41. The positioning hole 412 is arranged along the radial direction of the main body 41 and communicates with the moving groove 411. The adjusting connecting portion 43 is arranged in the moving groove 411. One end of the adjusting connecting portion 43 away from the adjusting end portion 42 penetrates through the moving groove 411 and extends out of the positioning hole 412. The adjusting connecting portion 43 is provided with a scale value.

[0033] When the connector 4 is pre-embedded, the second end surface 414 is flush with the wall surface of the structural side wall. When the structural side wall is arranged obliquely, before the connector 4 is pre-embedded, an operator pulls the adjusting connecting portion 43 to drive the adjusting end portion 42 to rotate relative to the second end surface 414 to adapt to the inclination angle of the structural side wall to be poured. After the adjusting connecting portion 43 penetrates through the positioning hole 412, the inclination angle of the adjusting end portion 42 is limited according to the scale value corresponding to the hole wall, so that the inclination angles of the second end surfaces 414 of the plurality of connectors 4 are consistent. Under the blocking action of the wall of the positioning hole 412, the adjusting connecting portion 43 cannot be easily moved, so as to realize self-locking of the position of the adjusting end portion 42, and facilitate stable state of the connector 4 during subsequent pouring.

[0034] With reference to Figure 3 and 4The pre-embedded device further comprises a protective cover 5, the protective cover 5 is fixedly connected with a positioning plug 51, a positioning hole 421 is arranged on the side of the adjusting end 42 away from the main body 41, and the positioning plug 51 is inserted into the positioning hole 421. The diameter of the protective cover 5 is greater than the outer diameter of the adapter 4, and the inner side cover surface of the protective cover 5 is in abutment with the structural side wall. A non-slip groove 52 is arranged on the side of the protective cover 5 away from the adapter 4.

[0035] The protective cover 5 extends into the adjusting end 42, and the positioning plug 51 extends into the positioning hole 421, which is beneficial to protect the cleanliness of the adapter 4 and reduce the risk of the adapter 4 being blocked by concrete and other substances. The protective cover 5 is in abutment with the structural side wall, and the fingers of the operator can be clamped in the non-slip groove 52 when taking, so as to prevent the hands from slipping off.

[0036] The implementation principle of the steel support replacement pre-embedded device is that the adapter 4 is lighter than the steel plate, and is convenient to pre-embed and install. The support replacement base 2 is connected with the adapter 4 through the connecting piece, so that the support and installation of the steel support 1 can be realized. The adjusting end 42 with adjustable inclination angle is arranged, so that the application range of the adapter 4 is wider, and can be adapted to various types of foundation pits or any position needing support in the foundation pit. At the same time, the support replacement base 2 is convenient to disassemble during the support replacement construction, so that the support replacement base 2 can be reused. The disassembly and assembly are convenient, and resources are saved.

[0037] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
