Description

Technical Field

[0001] This invention relates to the field of building energy conservation and environmental protection technology, and in particular to a micro-disturbance reinforcement structure for existing buildings. Background Technology

[0002] For existing buildings that have problems such as aging, increased load due to functional renovations, disaster damage, design defects, and foundation settlement, reinforcement can be carried out to ensure structural safety and extend service life.

[0003] The reinforcement of existing buildings typically includes foundation reinforcement to address uneven settlement, wall reinforcement to address insufficient shear strength and crack propagation, and beam-column joint reinforcement to address insufficient load-bearing capacity.

[0004] Current methods for reinforcing existing buildings often result in significant damage, complex construction procedures, and long construction periods. For example, when reinforcing existing concrete columns, methods such as increasing the cross-section or wet-type external steel cladding are commonly used. Furthermore, existing concrete column reinforcement methods only increase the column's load-bearing capacity and cannot address the issue of high thermal conductivity in concrete columns, leading to heat absorption and temperature fluctuations in summer and heat dissipation and temperature drops in winter, resulting in increased indoor temperature and energy consumption. Summary of the Invention

[0005] The purpose of this invention is to provide a micro-disturbance reinforcement structure for existing buildings, so as to solve the problem that the existing reinforcement process for concrete columns of existing buildings causes large disturbance to the original column and cannot improve the thermal bridging effect of the concrete column.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a micro-disturbance reinforcement structure for existing buildings, comprising:

[0007] A steel plate has a bent edge on one side and an insertion part on the opposite side. Four steel plates are arranged circumferentially on the outer side of the original column. The bent edge includes a flat plate part and an arc-shaped plate part. The flat plate part has several insertion holes arranged along the axis of the original column. The outer side of the arc-shaped plate part contacts the original column. The insertion part has several insertion joints arranged along the axis of the original column. The position of the insertion joints corresponds to the insertion holes. The insertion joint of one steel plate is inserted into the insertion hole of the adjacent steel plate.

[0008] Autoclaved aerated concrete (AAC) panels are fixedly mounted on a steel plate.

[0009] As a further description of the above technical solution:

[0010] The connector includes a rod body, a connecting ring, and external support rods. The connecting ring is detachably mounted on the rod body, and the connecting ring is provided with several external support rods arranged circumferentially, with the ends of the external support rods extending away from the rod body.

[0011] As a further description of the above technical solution:

[0012] The connecting ring is threaded onto the rod.

[0013] As a further description of the above technical solution:

[0014] The connecting ring is fitted onto the rod body, and the connecting ring and the rod body are interference fit.

[0015] As a further description of the above technical solution:

[0016] A transverse connecting rod is provided between the two external support rods on one side of the insertion hole.

[0017] As a further description of the above technical solution:

[0018] The connector is a slotted hole.

[0019] As a further description of the above technical solution:

[0020] A rubber pad layer is provided on one of the opposite end faces of the autoclaved aerated concrete slab.

[0021] As a further description of the above technical solution:

[0022] The autoclaved aerated concrete (AAC) panels have symmetrically arranged inclined surfaces on both sides, and the inclined surface of one AAC panel is in contact with the inclined surface of the adjacent AAC panel.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] 1. In this invention, after the autoclaved aerated concrete (AAC) panels are covered on the surface of the original column, the thermal insulation capacity is effectively improved, the heat conduction is significantly blocked, and the thermal bridging effect is reduced, thereby effectively reducing the temperature fluctuation inside the existing building and reducing energy consumption, achieving energy conservation and environmental protection.

[0025] 2. In this invention, the original concrete column is reinforced by a composite surface module composed of steel plates and autoclaved aerated concrete panels. The composite surface modules are interlocked through connectors and holes, eliminating the need to damage the original column or other existing building components, thus minimizing construction disturbance and effectively improving the seismic resistance of the existing building.

[0026] 3. In this invention, the arc-shaped plate part of the bent edge of the steel plate abuts against the original column. The arc-shaped plate part elastically contacts the original column through its own elastic deformation ability, which can effectively compensate for the unevenness of the surface of the original column and improve the impact resistance of the steel plate edge.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0039] Example 1

[0040] Please see Figure 1-7 This invention provides a technical solution: a micro-disturbance reinforcement structure for existing buildings, comprising:

[0041] A steel plate 1 has a bent edge 11 on one side and an insertion part 12 on the opposite side. Four steel plates 1 are arranged circumferentially on the outer side of the original column 9. The bent edge 11 includes a flat plate part 111 and an arc-shaped plate part 112. The flat plate part 111 is perpendicular to the steel plate 1. The flat plate part 111 is provided with a number of insertion holes 113 arranged along the axis of the original column 9. The outer side of the arc-shaped plate part 112 contacts the original column 9. The insertion part 12 is provided with a number of insertion connectors 121 arranged along the axis of the original column 9. The position of the insertion connectors 121 corresponds to the insertion holes 113. The insertion connector 121 of one steel plate 1 is inserted into the insertion hole 113 of the adjacent steel plate 1.

[0042] Autoclaved aerated concrete slab 2 is fixedly installed on steel plate 1.

[0043] The original concrete column 9 is reinforced on the outside by a composite surface module consisting of steel plate 1 and autoclaved aerated concrete board 2. The composite surface modules are interlocked with each other through connectors 121 and insertion holes 113, without damaging the original column 9 or other existing building parts, achieving a renovation with minimal construction disturbance and effectively improving the seismic resistance of the existing building.

[0044] The arc-shaped plate portion 112 of the bent edge 11 on one side of the steel plate 1 abuts against the original column 9. The arc-shaped plate portion 112 elastically contacts the original column 9 through its own elastic deformation ability, which can effectively compensate for the unevenness of the surface of the original column 9 and improve the impact resistance of the edge of the steel plate 1.

[0045] After autoclaved aerated concrete (AAC) panels are applied to the surface of the original column 9, they effectively improve thermal insulation, significantly block heat conduction, and reduce the thermal bridging effect, thereby effectively reducing temperature fluctuations inside the existing building and reducing energy consumption, achieving energy conservation and environmental protection.

[0046] The connector 121 includes a rod 1211, a connecting ring 1212, and an outer support rod 1213. The connecting ring 1212 is detachably mounted on the rod 1211. The connecting ring 1212 is provided with a plurality of circumferentially arranged outer support rods 1213, and the ends of the outer support rods 1213 extend away from the rod 1211.

[0047] When the connector 121 is inserted into the connector hole 113, the outer support rod 1213 is first squeezed to fit against the connecting ring 1212. After the outer support rod 1213 passes through the connector hole 113, the end of the outer support rod 1213 abuts against the back of the flat plate 111, thereby locking the connector 121 and the connector hole 113.

[0048] The insertion hole 113 is an oblong hole, which facilitates the insertion and locking of the bent edges 11 and insertion parts 12 of the two steel plates 1, and provides sliding space for the insertion connector 121 in the insertion hole 113, thereby improving the impact resistance.

[0049] A rubber pad layer 21 is provided on one of the opposite end faces of the autoclaved aerated concrete panel 2 to prevent the autoclaved aerated concrete panel 2 from colliding and damaging the existing building's top surface and ground surface during the reinforcement construction process, and to further prevent damage to the existing building.

[0050] The autoclaved aerated concrete (AAC) slab 2 has symmetrically arranged splicing ramps 22 on both sides. The splicing ramp 22 of one AAC slab 2 contacts the splicing ramp 22 of the adjacent AAC slab 2, effectively controlling the splicing joint between two adjacent AAC slab 2.

[0051] Working principle: During the reinforcement of the original column 9, a single steel plate 1 is first fixed to the autoclaved aerated concrete slab 2 to form a single composite surface module. Then, the two composite surface modules are spliced ​​and assembled into a pre-assembled part. The cross-section of the pre-assembled part is "L" shaped. Then, the two pre-assembled parts are spliced ​​and assembled on the outside of the original column 9 to complete the reinforcement of the original column 9.

[0052] Example 2

[0053] This embodiment further improves upon the above embodiment by providing the following technical solution: the connecting ring 1212 is threaded onto the rod 1211. This allows the position of the connecting ring 1212 on the rod 1211 to be adjusted, and the engagement effect between the connector 121 and the connector hole 113 can be flexibly adjusted according to the thickness of the bent edge 11 and the bending condition of the bent edge 11.

[0054] Example 3

[0055] This embodiment further improves upon the above embodiment by incorporating the following technical solution: the connecting ring 1212 is fitted onto the rod 1211, with an interference fit between the connecting ring 1212 and the rod 1211. This allows the connecting ring 1212 to detach from the rod 1211.

[0056] When it is necessary to disassemble the composite surface module, pull the composite surface module outward to unlock it by disengaging the connecting ring 1212 from the rod 121.

[0057] Example 4

[0058] This embodiment further improves upon the above embodiment by providing the following technical solution: a transverse connecting rod 1214 is provided between the two outer support rods 1213 on one side of the insertion hole 113. The transverse connecting rod 1214 is located at the end of the outer support rod 1213, replacing the end of the outer support rod 1213 in abutting against the back of the flat plate 111, effectively improving the deformation resistance of the outer support rod 1213 and ensuring the locking of the insertion connector 121 with the insertion hole 113.

[0059] The two external support rods 1213 and the transverse connecting rod 1214 can be designed as a single piece to further improve their resistance to deformation. Specifically, a single metal rod can be bent and formed, with both ends fixedly mounted on the connecting ring 1212.

[0060] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
