Description

Technical Field

[0001] The utility model relates to the technical field of earthquake-resistant reinforcement of existing buildings, in particular to a thermal insulation integrated prefabricated wall panel reinforcement structure. Background Art

[0002] At present, there are a large number of existing housing in my country. According to statistics, there are about 311 million existing housing units in urban areas across the country, of which about 120 million units were built before 2000, accounting for 40%. The scale of existing housing has reached nearly 40 billion m 2 The average age of existing houses in China is 40 to 50 years old, with a large number of them being masonry structures. Most of these structures have low seismic performance, posing safety risks. As the age of existing houses increases, the proportion of older homes continues to rise, and the safety risks of existing housing stock are increasing year by year. There is an urgent need to carry out seismic reinforcement of existing residential buildings. At the same time, the current renovation of existing residential buildings has evolved from simple structural reinforcement to a comprehensive stage of functional, energy-saving, green, and low-carbon performance improvement. A large number of residential buildings require energy-saving renovations, and the demand for exterior insulation renovations is also increasing year by year.

[0003] my country has already conducted extensive seismic reinforcement and energy-saving retrofitting of existing masonry structures, but existing technologies still present challenges. On the one hand, traditional seismic reinforcement techniques involve extensive on-site work, high levels of wet work, significant waste, high levels of pollution, and difficulty ensuring construction quality. Furthermore, the reinforcement process can impact the normal use of homes and require the relocation of residents, making seismic reinforcement implementation often difficult. On the other hand, structural reinforcement and energy-saving retrofits are generally implemented in two phases, resulting in low efficiency. Exterior wall insulation systems still utilize a traditional thin-film plaster system, which, over time, is prone to hollowing, cracking, and falling apart, posing a fire hazard. This significantly impacts the quality and finish of residential buildings, and can even cause loss of life and property. Utility Model Content

Detailed implementation manners

[0042] The following will specifically describe the preferred embodiments of the present invention in conjunction with the accompanying drawings. Among them, the accompanying drawings form a part of the present invention and are used together with the embodiments of the present invention to explain the principle of the present invention, and are not used to limit the scope of the present invention.

[0043] Embodiment 1

[0044] A specific embodiment of the present invention, as Figures 1-11 shown, discloses a thermal insulation integrated precast wallboard reinforcement structure, including an existing masonry wall 1 and an insulation board layer 2, a precast concrete wallboard layer 3, and a grouting layer 4 provided outside the existing masonry wall 1. The insulation board layer 2, the precast concrete wallboard layer 3, and the grouting layer 4 are arranged in sequence from outside to inside.

[0045] In this embodiment, the precast concrete wallboard layer 3 is prefabricated in the factory. After transporting the prefabricated precast concrete wallboard layer 3 to the site, it is connected to the existing masonry wall 1. A reliable connection method is used to connect the precast wallboard to the existing masonry wall 1 to form a whole, achieving the goal of restraining the original masonry structure and improving the overall seismic performance of the structure. At the same time, seismic reinforcement and external thermal insulation renovation can be realized.

[0046] In order to reliably connect the insulation board layer 2 and the precast concrete wallboard layer 3 to the existing masonry wall 1, referring to Figure 3 、 Figure 4、 Figure 5 、 Figure 6 and Figure 7 As shown, the reinforcement structure also includes embedded steel members 5, first connecting bolts 6, and second connecting bolts 7. The embedded steel members 5 are disposed within the precast concrete wall panel layer 3. As can be understood, through-holes 8 are provided in the precast concrete wall panel layer 3 to form a grouting area. The embedded steel members 5 are disposed within the through-holes 8. The first connecting bolts 6 connect the embedded steel members 5 to the existing masonry wall 1, and the second connecting bolts 7 connect adjacent embedded steel members 5. It should be noted that the first connecting bolts 6 are single-headed bolts, while the second connecting bolts 7 are studded bolts. Preferably, the embedded steel members 5 are uncovered rectangular parallelepiped shell structures.

[0047] Consider the need to inject grout (high-strength grouting material) into the gap between the precast concrete wall panel layer 3 and the existing masonry wall 1 to form a grouting layer 4, such as Figure 3 As shown, the bottom of the embedded steel part 5 is provided with a grouting hole 9 and a first bolt hole 10. Preferably, there are two grouting holes 9, and the two grouting holes 9 are located on both sides of the first bolt hole 10. One end of the first connecting bolt 6 passes through the first bolt hole 10 and is connected to the existing masonry wall 1, and forms a gap between the existing masonry wall 1 and the precast concrete wall panel layer 3. High-strength grouting material is injected into the gap through the grouting hole 9 to form a grouting layer 4, which can effectively strengthen the coordinated work of the new and old structures to improve the seismic resistance of the existing building. It should be noted that the inner cavity of the embedded steel part 5 also needs to be sealed (such as with high-strength grouting material or concrete).

[0048] It is worth noting that the reference Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, for an existing masonry structure house with a ring beam 11 and a structural column 12, both sides of the ring beam 11 and both sides of the structural column 12 are provided with embedded steel parts 5, and the second connecting bolt 7 passes through the ring beam 11 to connect the embedded steel parts 5 on both sides of the ring beam 11, and the second connecting bolt 7 passes through the structural column 12 to connect the embedded steel parts 5 on both sides of the structural column 12. It can be understood that the side wall of the embedded steel parts 5 is provided with a second bolt hole (not shown in the figure). For a masonry structure house without an additional ring beam 11 and a structural column 12, the two embedded steel parts 5 are arranged adjacent to each other and connected by the second connecting bolt 7, that is, the embedded steel parts 5 originally located on both sides of the ring beam 11 and the structural column 12 are put together. It should be noted that if it is determined that the original ring beam 11 and the structural column 12 have been severely damaged and cannot be continued to be used or are not suitable for implementation of the post-anchoring construction operation, the original ring beam 11 and the structural column 12 can also be removed and reinforced.

[0049] It should be noted that when the outer surface is made of thin plaster, a plaster layer and a finishing layer can be applied on the outer side of the insulation board layer 2; Figure 2As shown, when decorative panels are used for exterior cladding, embedded decorative panel parts 20 are pre-embedded within the insulation board layer 2 and the precast concrete wallboard layer 3. Adaptable interface embedded parts can be selected based on the connection requirements of different types of decorative panels. The decorative panel keels can simply be connected to the embedded parts, significantly reducing the workload of post-anchoring embedded parts and post-insulation in traditional practices. Specifically, the embedded decorative panel parts 20 include a "T"-shaped connector 21 and a "U"-shaped connector 22. The majority of the "T"-shaped connector 21 is pre-embedded within the precast concrete wallboard layer 3, with a smaller portion located within the insulation board layer 2. One end of the "U"-shaped connector 22 connects to the portion of the "T"-shaped connector 21 located within the insulation board layer 2, while the other end extends out of the insulation board layer 2 for connection to the decorative panel.

[0050] Example 2

[0051] Another specific embodiment of the present invention is as follows Figure 12-15 As shown, a thermal insulation integrated prefabricated wall panel reinforcement structure is disclosed, such as Figure 12 and Figure 14 As shown, the difference from Example 1 is that a post-cast strip 13 is provided between adjacent precast concrete wall panels 3, and no embedded steel parts 5 are used. Figure 12 and Figure 13 As shown, for the masonry structure that has been reinforced by adding ring beams 11 and structural columns 12, two adjacent precast concrete wall panels 3 are anchored and overlapped with the structural columns 12 at the post-cast strips 13. Specifically, post-cast strip horizontal reinforcements 14 are anchored in the structural columns 12, and inner blade steel meshes 15 are provided in the precast concrete wall panel layer 3. The inner blade steel meshes 15 extend out of the side portions of the precast concrete wall panel layer 3 to form end hook-shaped horizontal and vertical reinforcements 16. The two ends of the post-cast strip horizontal reinforcements 14 are overlapped with the reinforcements 16 on both sides of the structural columns 12, and a whole is formed after the concrete is poured. At the same time, post-cast strip anchor reinforcements 17 are used to connect the post-cast strips 13 and the existing masonry wall 1. The post-cast strip vertical reinforcements 18 are overlapped with the reinforcements 16 and the post-cast strip anchor reinforcements 17, so that the precast concrete wall panel layer 3 and the existing masonry wall 1 are tied together to form a whole. It is worth noting that at the post-cast zone 13, the side of the precast concrete wall panel layer 3 extends out of the insulation panel layer 2 and can be used as a template for pouring concrete in the post-cast zone during the construction process.

[0052] For masonry structures or parts that have not been reinforced by adding ring beams 11 and structural columns 12, such as Figure 14 and Figure 15 As shown, two adjacent precast concrete wall panels 3 are connected by anchoring and overlapping in the post-cast strip 13, and are also anchored to the existing masonry wall 1. Specifically, the post-cast strip anchor bar 17 is anchored into the existing masonry wall 1, and the hook-shaped horizontal and vertical steel bars 16 (reference Figure 13), the side panels of the precast concrete wall panel layer 3 on the other side extend out L-shaped horizontal reinforcement 19, the steel bars 16, the post-cast strip anchor bars 17, the post-cast strip vertical reinforcement 18, and the L-shaped horizontal reinforcement 19 are overlapped and connected, and concrete is poured in the cavity to form a reliable connection between the precast concrete wall panel layers 3 and between the precast concrete wall panel layers 3 and the existing masonry wall 1.

[0053] In this embodiment, the insulation board layer 2, precast concrete wall panel layer 3, and grouting layer 4 are installed only on the exterior of the existing masonry wall 1, enabling construction without entering residents. This allows for a high degree of industrialization, a short construction period, and minimal pollution on the construction site, significantly reducing adverse impacts on residents' lives and production. Utilizing integrated exterior wall insulation technology, the insulation board serves as the formwork for the reinforced concrete inner slab. After concrete pouring, the insulation layer and structural layer are fully bonded. Insulation connectors, combined with adhesive and anchoring, effectively address issues such as hollowing, cracking, and detachment. Most of the construction process is completed in the factory, reducing on-site wet work. No formwork is required on-site, and the insulation is installed simultaneously, improving construction and installation efficiency and reducing formwork and labor costs. Dry connection is primarily used for connection to the existing masonry wall 1, further improving installation efficiency and reducing on-site pollution. Decorative panel embedded parts 20 can be pre-embedded within the insulation board layer 2 and precast concrete wall panel layer 3. Adaptable interface embedded parts can be selected based on the connection requirements of different decorative panel types, allowing for diverse exterior wall decoration options. This embodiment can achieve the goals of "rapid, low-carbon, and reduced impact on normal use" in seismic reinforcement and energy-saving transformation, and realize the integrated improvement of seismic performance and energy saving.

[0054] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
