A corbel component for internal support and main structure stress transfer

Abstract

This invention belongs to the field of building construction technology and discloses a corbel component for transferring the load between internal support and the main structure, aiming to solve the problem of high construction costs associated with existing temporary internal supports for foundation pits. This invention connects the main structure within the foundation pit to the support components via a corbel assembly to form a unified whole. During construction, the corbel assembly is first constructed in conjunction with the main structure within the foundation pit, and then the support components, serving as temporary supports, are connected to the corbel assembly. This allows the corbel assembly and the main structure to function as part of the temporary foundation pit support structure, thereby reducing the amount of construction work and the construction period, ultimately saving on project costs.

Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically relating to a corbel component that converts internal support and main structural load. Background Technology

[0002] Foundation pit support refers to the measures taken to support, reinforce, and protect the sidewalls of the foundation pit and its surrounding environment to ensure the safety of underground structure construction and the surrounding environment. Internal supports used for foundation pit support include temporary internal supports and permanent support structures.

[0003] In existing technologies, the main structure and temporary internal supports are constructed separately and independently, resulting in serious material waste and high construction costs. Summary of the Invention

[0004] In order to solve the problem of high construction costs of existing temporary internal supports for foundation pits, this invention provides a corbel component for the transfer of stress between internal supports and the main structure.

[0005] To solve the technical problem, the technical solution adopted by this invention is as follows:

[0006] A corbel member for internal support and main structure stress conversion, characterized in that it includes at least one corbel member body, the corbel member body includes a corbel assembly and a support assembly, the corbel assembly includes a corbel steel mesh and concrete poured on and covering the corbel steel mesh;

[0007] The corbel reinforcement mesh includes horizontal reinforcement mesh segments and trapezoidal reinforcement mesh segments located at the upper end of the horizontal reinforcement mesh segments. The horizontal reinforcement mesh segments include first horizontal bars and first vertical bars, which are bundled together to form a rectangular horizontal reinforcement mesh segment. One end of the horizontal reinforcement mesh segment extends out of the corbel assembly and connects to the main structure. The trapezoidal reinforcement mesh segment includes second horizontal bars and second vertical bars, which are bundled together to form a trapezoidal reinforcement mesh segment with a trapezoidal longitudinal cross-section. The ends of the vertical reinforcing bars extend into the horizontal section of the reinforcing mesh. Each second vertical reinforcing bar has a first tie bar on the inclined surface of the trapezoidal section of the reinforcing mesh. The upper end of the first tie bar is spaced from the upper surface of the trapezoidal section of the reinforcing mesh. The lower end of the first tie bar extends obliquely into the horizontal section of the reinforcing mesh along the inclined surface of the trapezoidal section of the reinforcing mesh. The upper end of the first tie bar is connected to a second tie bar. The upper end of the second tie bar is connected to the first tie bar. The lower end of the second tie bar extends obliquely to the lower end of the surface corresponding to the inclined surface of the trapezoidal section of the reinforcing mesh and then extends vertically into the horizontal section of the reinforcing mesh.

[0008] The support assembly includes a first layer support assembly and at least one second layer support assembly. The first layer support assembly includes a first layer of reinforcing mesh and concrete poured into and covering the first layer of reinforcing mesh. The second layer support assembly includes a second layer of reinforcing mesh and concrete poured into and covering the second layer of reinforcing mesh. The first layer of reinforcing mesh is connected to a trapezoidal segment of reinforcing mesh, and at least one second layer of reinforcing mesh in the second layer support assembly is connected to a horizontal segment of reinforcing mesh.

[0009] The first layer of steel mesh includes a third horizontal steel bar and a third vertical steel bar. The third horizontal steel bar and the third vertical steel bar are tied together to form a rectangular first layer of steel mesh. The third vertical steel bars at both ends of the first layer of steel mesh are connected together by a third tie bar. A fourth tie bar connects the middle of the third tie bar to the bottommost third horizontal steel bar.

[0010] The second layer of steel mesh includes fourth horizontal steel bars and fourth vertical steel bars. The fourth horizontal steel bars and fourth vertical steel bars are tied together to form a rectangular second layer of steel mesh. A fifth tie bar connects two adjacent fourth horizontal steel bars located in the middle of the fourth vertical steel bars. Two sixth tie bars are connected to the left and right sides of the fifth tie bar respectively. One end of the sixth tie bar is connected to the fifth tie bar, and the other end of the sixth tie bar is connected to the fourth horizontal steel bars located above and below the fifth tie bar respectively. A seventh tie bar connects the middle of the lowest fourth horizontal steel bar and the adjacent fourth horizontal steel bar above it.

[0011] Adjacent corbel components are fixedly connected together by I-beams.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In use, the internal support and main structure load-bearing corbel component of this invention connects the main structure within the foundation pit to the support components, forming a unified whole. During construction, the corbel components are first constructed along with the main structure within the foundation pit. Then, the support components, serving as temporary supports for the foundation pit, are connected to the corbel components. This allows the corbel components and the main structure to function as part of the temporary foundation pit support structure, thereby reducing the amount of construction work and the construction period, ultimately saving on project costs. Experience has shown that compared to existing technologies that require separate construction of temporary foundation pit supports, the structure of this invention significantly reduces the amount of steel reinforcement and concrete used, saving 28-32.5% on project costs.

[0014] The optimized structural design of the corbel reinforcement mesh and the first and second layer reinforcement mesh of the support component of the present invention can reduce the amount of steel reinforcement while meeting the structural strength requirements. At the same time, it can facilitate the disassembly of the corbel component and the replacement and removal of the support component, thereby reducing the difficulty of subsequent construction operations.

Detailed Implementation

[0025] The present invention will be further described below with reference to embodiments. These embodiments are merely some, not all, of the embodiments of the present invention. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the protection scope of the present invention.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] Referring to the accompanying drawings, the internal support and main structure force conversion corbel component of the present invention includes at least one corbel component body, the corbel component body includes corbel assembly 1 and support assembly 2, the corbel assembly 1 includes corbel steel mesh and concrete poured on and covering the corbel steel mesh.

[0028] The main structure described in this invention refers to the building body constructed in the foundation pit, which is understood by those skilled in the art and will not be elaborated further here.

[0029] Combined with appendix Figure 2 -Appendix Figure 5 In most cases, the corbel component body is composed of multiple corbel component bodies as the main structure of the corbel. Therefore, each corbel component body needs to be connected and fixed. In some embodiments, adjacent corbel components 1 in the corbel component body are connected by I-beams. For example, the end of the I-beam is fixedly connected to the corbel component 1 by bolts. Adjacent support components 2 in the corbel component body are integrally formed by I-beams or concrete pouring.

[0030] Combined with appendix Figure 2 -Appendix Figure 5Depending on the main structure, the corbel component 1 can also be designed with a multi-layer structure. Adjacent corbel components 1 are connected together by steel columns 3 (or steel pipes), and the lower end of the steel columns 3 is fixedly installed on the foundation 4. This is clear to those skilled in the art and will not be elaborated further here.

[0031] Combined with appendix Figure 6 The corbel reinforcement mesh of the present invention includes a horizontal section reinforcement mesh 12 and a trapezoidal section reinforcement mesh 11 located at the upper end of the horizontal section reinforcement mesh 12. The horizontal section reinforcement mesh 12 includes a first horizontal reinforcement bar 1201 and a first vertical reinforcement bar 1202. The first horizontal reinforcement bar 1201 and the first vertical reinforcement bar 1202 are bundled together to form a rectangular horizontal section reinforcement mesh 12. It should be noted here that, in conjunction with the attached... Figure 6 This invention describes a schematic diagram of the longitudinal cross-section of the horizontal segment steel mesh 12 and the trapezoidal segment steel mesh 11 of the corbel steel mesh. Since the corbel assembly itself has thickness, the thickness direction is not shown. Several horizontal segment steel meshes 12 and several trapezoidal segment steel meshes 11 of the corbel assembly 1 are connected together by steel bars along the thickness direction, which is clear to those skilled in the art and will not be elaborated further here. One end of the horizontal segment steel mesh 12 extends out of the corbel assembly 1 and connects to the main structure; that is, the first horizontal steel bar 1201 of the horizontal steel mesh 12 extends out of the corbel assembly 1 and is tied together with the steel bars of the main structure, thereby forming an organic whole at one end of the corbel assembly 1.

[0032] Combined with appendix Figure 6The trapezoidal segment steel mesh 11 of the present invention includes a second horizontal steel bar 1101 and a second vertical steel bar 1102. The second horizontal steel bar and the second vertical steel bar are tied together to form a trapezoidal segment steel mesh 11 with a trapezoidal longitudinal cross section. The end of the second vertical steel bar 1102 extends into the horizontal segment steel mesh 12 and is connected to the first vertical steel bar in the horizontal segment steel mesh 12. Each second vertical steel bar 1102 is provided with a first tie bar 1103 on the inclined surface of the trapezoidal segment steel mesh. It should be noted that the second vertical steel bars 1102 used to form the inclined surface are themselves connected with steel bars to form the inclined surface. The first tie bar 1103 of the present invention is equivalent to an additional steel bar added on the inclined surface. The upper end of the first tie bar 1103 is spaced from the upper surface of the trapezoidal section steel mesh 11. The lower end of the first tie bar 1103 extends obliquely into the horizontal section steel mesh 12 along the inclined surface of the trapezoidal section steel mesh 11. The first tie bar 1103 extends into the horizontal section steel mesh 12 and is connected to the horizontal section steel mesh. The upper end of the first tie bar 1103 is connected to the second tie bar 1104. The upper end of the second tie bar 1104 is connected to the first tie bar 1103. The lower end of the second tie bar 1104 extends obliquely to the lower end of the surface corresponding to the inclined surface of the trapezoidal section steel mesh 11 and then extends vertically into the horizontal section steel mesh 11. That is to say, one end of the second tie bar 1104 is located in the upper half of the inclined surface of the trapezoidal section steel mesh 11. The other end of the second tie bar obliquely penetrates the trapezoidal section steel mesh and extends vertically downward into the horizontal section steel mesh and is connected to the horizontal section steel mesh.

[0033] The support component 2 of the present invention includes a first layer support component and at least one second layer support component. The first layer support component includes a first layer of reinforcing mesh 21 and concrete poured into and covering the first layer of reinforcing mesh 21. The second layer support component includes a second layer of reinforcing mesh 22 and concrete poured into and covering the second layer of reinforcing mesh 22. The first layer of reinforcing mesh 21 is connected to the trapezoidal segment reinforcing mesh 11, and at least one second layer of reinforcing mesh 22 of the second layer support component is connected to the horizontal segment reinforcing mesh 12. Since the number of second layer support components varies depending on the construction requirements, in order to ensure a tighter connection between the corbel component 1 and the support component 2 and to facilitate the transfer of force between the inner support (support component 2) and the main structure through the corbel component 1, it is necessary to ensure that the second layer of reinforcing mesh of at least one second layer support component is connected to the horizontal segment reinforcing mesh 12 during construction.

[0034] Combined with appendix Figure 7The first layer of steel mesh 21 includes a third horizontal steel bar 2101 and a third vertical steel bar 2102. The third horizontal steel bar 2101 and the third vertical steel bar 2102 are tied together to form a rectangular first layer of steel mesh 21. The third vertical steel bars 2102 at both ends of the first layer of steel mesh 21 are connected together by a third tie bar 2103. A fourth tie bar 2104 is connected between the middle of the third tie bar 2103 and the bottommost third horizontal steel bar 2101.

[0035] Combined with appendix Figure 8 The second layer of steel mesh 22 includes a fourth horizontal steel bar 2201 and a fourth vertical steel bar 2202. The fourth horizontal steel bar and the fourth vertical steel bar are tied together to form a rectangular second layer of steel mesh 22. A fifth tie bar 2203 is connected between two adjacent fourth horizontal steel bars 2201 located in the middle of the fourth vertical steel bar 2202. Two sixth tie bars 2204 are connected to the left and right sides of the fifth tie bar 2203 respectively. One end of the sixth tie bar 2204 is connected to the fifth tie bar 2203, and the other end of the sixth tie bar 2204 is connected to the fourth horizontal steel bar 2201 located above and below the fifth tie bar 2203 respectively. A seventh tie bar 2205 is connected between the middle of the lowest fourth horizontal steel bar 2201 and the middle of the adjacent fourth horizontal steel bar 2201 above it.

[0036] In use, the internal support and main structure load-bearing corbel component of this invention connects the main structure within the foundation pit to the support components, forming a unified whole. During construction, the corbel components are first constructed along with the main structure within the foundation pit. Then, the support components, serving as temporary supports for the foundation pit, are connected to the corbel components. This allows the corbel components and the main structure to function as part of the temporary foundation pit support structure, thereby reducing the amount of construction work and the construction period, ultimately saving on project costs. Experience has shown that compared to existing technologies that require separate construction of temporary foundation pit supports, the structure of this invention significantly reduces the amount of steel reinforcement and concrete used, saving 28-32.5% on project costs.

[0037] The optimized structural design of the corbel reinforcement mesh and the first and second layer reinforcement mesh of the support component of the present invention can reduce the amount of steel reinforcement while meeting the structural strength requirements. At the same time, it can facilitate the disassembly of the corbel component and the replacement and removal of the support component, thereby reducing the difficulty of subsequent construction operations.
