Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to a reinforcement structure for composite buildings in old residential communities and a method for energy-saving renovation. Background Technology

[0002] Old residential communities refer to urban residential communities built in the 1980s and early 1990s. These communities are generally multi-story buildings that have gradually shown varying degrees of aging and damage as they have been used for many years, posing safety hazards to normal use.

[0003] In order to improve the seismic resistance and service life of old residential communities and actively explore the application of new energy technologies in buildings, this invention aims to develop a composite reinforcement structure for old residential communities supplemented with solar photovoltaic panels, which will ensure the overall stability of the building while actively exploring energy-saving renovation of existing buildings. Summary of the Invention

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a reinforcement structure and energy-saving renovation method for composite buildings in old residential areas.

[0005] The technical solution of the present invention to achieve the above objectives is a composite reinforcement structure and reinforcement method for old residential communities, comprising an internal reinforcement structure and an external reinforcement structure, wherein the internal reinforcement structure and the external reinforcement structure have a connecting structure.

[0006] The internal reinforcing structure includes: several internal reinforcing rods, several expansion sleeves, and several connecting ribs;

[0007] Multiple insertion holes are provided on the surface of the wall. At least three synchronous slots are opened at equal angles on the outer wall of the expansion sleeve. Multiple engagement slots for limiting horizontal movement are provided at the bottom of the synchronous slots. Both ends of the connecting rib are provided with engagement teeth that match the engagement slots. Pressing and fixing the left and right ends of the connecting rib in the synchronous slots makes the engagement teeth match and contact the engagement slots, so that multiple expansion sleeves can rotate and move horizontally synchronously into the insertion holes.

[0008] A blind groove is opened on the outer wall of the wall. An integrally formed retaining rib is provided on the expansion sleeve located at the outer end of the inner reinforcing rod. The retaining rib is squeezed and inserted into the blind groove. The outer blind groove restricts the expansion sleeve at the outer end of the reinforcing rod, and the connecting rib on the expansion sleeve restricts the expansion sleeve located inside the through hole.

[0009] The external reinforcement structure includes: several hexagonal reinforcing members, reinforcing internal support members, several connecting columns, and several reinforcing pins;

[0010] The hexagonal reinforcing members are interconnected by a number of reinforcing pins and are reinforcedly installed inside the hexagonal reinforcing members. The reinforcing inner support member is a number of intersecting and integrally formed reinforcing ribs.

[0011] The central portion of each of the hexagonal reinforcing members, spaced 0.2m-0.4m apart, is connected to the outer end of the reinforcing rod via a connecting column;

[0012] The hexagonal reinforcing member connected to the connecting column and the inner reinforcing rod has a circular groove in its center to wrap around the connecting column. The thickness of the other hexagonal reinforcing members is between 1cm and 1.5cm.

[0013] The hexagonal reinforcing members are all attached to the wall surface, and a photovoltaic structure is also provided on the hexagonal reinforcing members.

[0014] Furthermore, the expansion sleeve located at the outer end of the inner reinforcing rod is threadedly engaged with the inner reinforcing rod.

[0015] Furthermore, the gap between the expansion sleeve and the insertion hole is filled with cement soil.

[0016] Furthermore, the photovoltaic structure includes: a solar photovoltaic panel, a back fixing frame, several mounting frames, several tensioning blocks, several mounting blocks, and spring components;

[0017] The solar photovoltaic panel is mounted on the back fixing frame, and several mounting brackets are set on the back fixing frame. The mounting block is mounted on the mounting brackets, and the left and right ends of the mounting block are provided with slots. The spring is installed in the slots, and the tensioning block is installed on one end of the spring.

[0018] By mounting the block close to the hexagonal reinforcement, the tension block is squeezed and forced to pass through the gap in the inner support member. Due to the tension of the spring, the tension block can first retract into the slot of the mounting block. After passing through the gap in the inner support member, it is reset by the tension of the spring, thus achieving a snap-fit ​​with the hexagonal reinforcement member and fixing the solar photovoltaic panel.

[0019] Furthermore, the reinforcing inner support member forms multiple triangular gaps at equal angles.

[0020] Furthermore, the mounting block is integrally formed and consists of multiple slots distributed at equal angles, with the slot located on the wall surface of the slot.

[0021] Furthermore, the photovoltaic panel is tilted.

[0022] 10. The reinforcement method using reinforced structures includes the following steps:

[0023] S1. Various components need to be prefabricated and transported to the construction site. First, holes are drilled in the wall surface to leave holes of sufficient depth, which can be between 40-100mm.

[0024] S2. Connect multiple expansion sleeves with connecting bars. The expansion sleeves used in this technical solution are separate, which can reduce the space of the expansion sleeves inside the wall and fill the gaps with concrete.

[0025] S3. Make blind grooves on the wall according to the location, so that the retaining rods on the expansion sleeves can enter the blind grooves to prevent the multiple expansion sleeves located inside the insertion hole from rotating.

[0026] S4. Insert the inner reinforcing rod into multiple expansion sleeves with the same diameter, and make a part of the reinforcing rod protrude from the wall.

[0027] S5. It adopts multiple independent hexagonal structures and connects them together with pins. This multiple hexagonal structure allows for flexible application and adaptability to various wall shapes.

[0028] S6. When installing reinforcing bars, a portion of them is exposed to the outside. The center of each hexagonal reinforcing member, spaced 0.2m-0.4m apart, is connected to the outer end of the reinforcing bar via a connecting column. This internal and external reinforcement achieves the reinforcement of the exterior walls of the old residential area.

[0029] S7. When installing solar photovoltaic panels, they need to be fixed to hexagonal reinforcing members. Specifically, a back fixing frame is set on the back of the solar photovoltaic panel, and an mounting frame is set on the frame. An installation block is set on the mounting frame, and a slot is set on the wall of the mounting block. A spring is added in the slot, and a tensioning block is set on one end of the spring.

[0030] S8: Specifically, by using the mounting block, bring it close to the hexagonal reinforcement, squeeze the tension block, and let it pass through the gap of the inner support member. Due to the tension of the spring member, the tension block can first retract into the slot of the mounting block. After passing through the gap of the inner support member, it is reset by the tension of the spring member, thus achieving the snap-fit ​​with the hexagonal reinforcement member and fixing the solar photovoltaic panel.

[0031] The present invention discloses a composite reinforcement structure and reinforcement method for old residential buildings. The present invention provides a reinforcement component that can be assembled. The component is characterized by being able to be installed on reinforcement points of multiple buildings, with flexible installation locations and strong applicability.

[0032] In addition, this case also has at least the following technical effects:

[0033] This technical solution takes into account that old buildings are prone to cracking under environmental changes and oxidation, and their compressive and extrusion resistance will decrease. This technical solution adopts a method of strengthening both the inside and outside of the wall to increase the stability of the building's exterior wall.

[0034] This design employs multiple independent hexagonal structures connected together by pins. This multiple hexagonal structure allows for flexible application and adaptability to various wall shapes.

[0035] This invention uses an installation block to bring it close to the hexagonal reinforcement member, compressing the tension block and allowing it to pass through the gap in the inner support member. Due to the tension of the spring member, the tension block can first retract into the slot of the installation block, and after passing through the gap in the inner support member, it can be reset by the tension of the spring member, thus achieving the snap-fit ​​with the hexagonal reinforcement member and fixing the solar photovoltaic panel.

[0051] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-14 As shown, a composite reinforcement structure and reinforcement method for old residential buildings are presented.

[0052] A composite reinforcement structure for old residential buildings includes an internal reinforcement structure and an external reinforcement structure, with a connecting structure between the internal reinforcement structure and the external reinforcement structure;

[0053] It should be noted that this technical solution takes into account that old buildings are prone to cracking under environmental changes and oxidation, and their compressive and extrusion resistance will decrease. Therefore, this technical solution adopts a method of strengthening both the inside and outside of the wall to increase the stability of the building's exterior wall.

[0054] Specifically, the internal reinforcement structure includes: several internal reinforcing rods 1, several expansion sleeves 2, and several connecting ribs 3;

[0055] Multiple insertion holes 5 are provided on the wall surface. At least three synchronous slots 6 are opened at equal angles on the outer wall of the expansion sleeve 2. Multiple engagement slots 7 for limiting horizontal movement are provided at the bottom of the synchronous slots 6. Engaging teeth 8 that match several engagement slots 7 are provided at both ends of the connecting rib 3. Press and fix the left and right ends of the connecting rib 3 in the synchronous slots 6 so that the engagement teeth 8 match and contact the engagement slots 7, so that multiple expansion sleeves 2 can rotate synchronously and move horizontally into the insertion holes 5.

[0056] A blind groove 9 is opened on the outer wall of the wall. An integrally formed retaining rib 12 is provided on the expansion sleeve 2 located at the outer end of the inner reinforcing rod 1. The retaining rib 12 is squeezed and inserted into the blind groove 9. The outer blind groove 9 restricts the expansion sleeve 2 at the outer end of the reinforcing rod, and the connecting rib 3 on the expansion sleeve 2 restricts the expansion sleeve 2 located inside the through hole 5.

[0057] It should be noted that in the specific construction of this technical solution, various components need to be prefabricated and transported to the construction site. First, holes need to be drilled in the wall surface to leave holes of sufficient depth, which can be between 40-100mm.

[0058] First, multiple expansion sleeves 2 are connected by connecting ribs 3. The expansion sleeves 2 used in this technical solution are separate, which can reduce the space of the expansion sleeves 2 inside the wall. Concrete can be added to the gaps to achieve greater stability. Therefore, connecting ribs 3 are used in this case to achieve fixation.

[0059] Meanwhile, considering that each expansion sleeve 2 is independent, and to ensure that multiple expansion sleeves 2 are controlled by one, a meshing groove 7 is set at the bottom of the synchronous notch 6 on the expansion sleeve 2. At the same time, meshing teeth 8 matching several meshing grooves are set at both ends of the connecting rib 3. The left and right ends of the connecting rib 3 are pressed and fixed in the synchronous notch 6, so that the meshing teeth 8 and the meshing groove 7 are matched and contacted. The expansion sleeve 2 located at the end of the insertion hole 5 is different from other expansion sleeves 2. Multiple retaining ribs 12 are set at equal angles on its outer wall, and blind grooves 9 are opened on the wall according to the position, so that the retaining ribs 12 on the expansion sleeve 2 enter the blind grooves 9. The purpose of this is to prevent the expansion sleeve 2 inside the inner insertion hole 5 from rotating.

[0060] Insert the inner reinforcing rod into multiple expansion sleeves 2 with the same diameter, and make a part of the outside of the reinforcing rod protrude from the wall;

[0061] The external reinforcement structure includes: several hexagonal reinforcing members 10, reinforcing internal support members 11, several connecting columns 4, and several reinforcing pins;

[0062] Several hexagonal reinforcing members 10 are interconnected by several reinforcing pins and reinforced inside the hexagonal reinforcing members 10. The reinforcing inner support member 11 consists of multiple intersecting and integrally formed reinforcing ribs.

[0063] The center of each hexagonal reinforcing member 10, spaced 0.2m-0.4m apart, is connected to the outer end of the reinforcing rod via a connecting column 4;

[0064] A circular groove is provided in the center of the hexagonal reinforcing member 10 that is connected to the inner reinforcing rod via the connecting column 4, which encloses the connecting column 4. The thickness of the other hexagonal reinforcing members 10 is between 1cm and 1.5cm.

[0065] Several hexagonal reinforcing members 10 are attached to the wall surface, and photovoltaic structures are also provided on the hexagonal reinforcing members 10.

[0066] This technical solution requires adding a fixing structure to the exterior of the wall. This design uses multiple independent hexagonal structures connected together by pins. This multiple hexagonal structure allows for flexible application and adaptability to various wall shapes. When installing the reinforcing rods, a portion of them is exposed externally. The central part of each hexagonal reinforcing member 10, spaced 0.2m-0.4m apart, is connected to the outer end of the reinforcing rod via a connecting column 4. This internal and external reinforcement strengthens the exterior wall of the old residential area. However, after the exterior wall is reinforced, simply exposing the reinforcing members is not aesthetically pleasing, and the lack of covering will cause them to rust, severely reducing their appearance. Therefore, this design adds a photovoltaic structure to the hexagonal reinforcing members 10, which not only enhances aesthetics but also improves practicality.

[0067] Furthermore, the expansion sleeve 2 located at the outer end of the inner reinforcing rod is threadedly engaged with the inner reinforcing rod.

[0068] Furthermore, cement soil is poured into the gap between the expansion sleeve 2 and the insertion hole 5.

[0069] Specifically, the photovoltaic structure includes: solar photovoltaic panel 14, back fixing frame 15, several mounting frames 16, several tensioning blocks 17, and several mounting blocks 18;

[0070] The solar photovoltaic panel 14 is mounted on the back fixing frame 15, and several mounting brackets 16 are set on the back fixing frame 15. The mounting block 18 is mounted on the mounting bracket 16. The left and right ends of the mounting block 18 are provided with slots 19. The spring member 13 is installed in the slot 19, and the tensioning block 17 is installed on one end of the spring member 13.

[0071] It should be noted that when installing the solar photovoltaic panel 14, this technical solution requires fixing it to the hexagonal reinforcement. Specifically, a back fixing frame 15 is first set on the back of the solar photovoltaic panel 14, and an embedding frame 16 is set on the frame. An installation block 18 is set on the embedding frame 16, and a slot 19 is set on the wall of the installation block 18. A spring 13 is added to the slot 19, and a tension block 17 is set on one end of the spring 13. Specifically, by bringing the installation block 18 close to the hexagonal reinforcement 10, the tension block 17 is squeezed and passes through the gap of the inner support member 11. Due to the tension of the spring 13, the tension block 17 can first retract into the slot 19 of the installation block 18, and after passing through the gap of the inner support member, it is reset by the tension of the spring 13, thus achieving the snap-fit ​​with the hexagonal reinforcement 10 and fixing the solar photovoltaic panel 14.

[0072] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
