Description

Technical Field

[0001] This application relates to the technical field of foundation construction for building engineering, and in particular to a seismic-resistant structure for building engineering. Background Technology

[0002] Self-built housing refers to houses and buildings constructed by individuals or entities owning their own land, organizing the construction themselves and hiring others for the work. Self-built housing is the mainstream traditional construction method in China, especially in rural areas. Rural residents almost exclusively rely on self-built housing to meet their housing needs, as they are not allowed to build outside urban planning areas or construction land boundaries. The selection of the foundation is a crucial step in the self-built housing process. Most existing self-built houses use cement or concrete to compact the foundation during construction to improve the house's earthquake resistance. However, in the event of an earthquake, due to the poor damping capacity of the foundation, the building structure deforms, causing irreparable damage and rendering the building unusable.

[0003] Related technologies include Chinese Patent Application Publication No. CN114775824A, which discloses a seismic-resistant structure for building engineering, including a base plate. A first seismic-resistant device is provided on the upper side of the base plate, and a second shock-absorbing device is provided on the upper side of the first seismic-resistant device. A placement plate is connected to the upper side of the second shock-absorbing device. The first seismic-resistant device includes a first seismic-resistant box. Multiple sets of first springs are evenly arranged on the four walls of the first seismic-resistant box. A base is connected to the side of the multiple sets of first springs away from the first seismic-resistant box. The second shock-absorbing device is located on the upper side of the base. The second shock-absorbing device includes a second seismic-resistant box. Multiple sets of third springs are evenly connected to the bottom wall of the inner cavity of the second seismic-resistant box.

[0004] Regarding the aforementioned technologies, the applicant has found that self-built houses are relatively heavy. If the multi-spring shock absorption and buffering technology mentioned above is adopted, the requirements for the number and strength of the springs are high, and it is also difficult to ensure the stability of the connection between the springs and related structures, resulting in greater construction difficulties. Therefore, a new technical solution needs to be designed to overcome the problem of poor seismic resistance of self-built houses. Summary of the Invention

[0005] The purpose of this application is to provide a seismic-resistant structure for building engineering, which can overcome the poor seismic resistance of self-built houses.

[0006] Firstly, this application provides a seismic-resistant structure for building engineering, which adopts the following technical solution.

[0007] An earthquake-resistant structure for building construction includes several independent supports and a foundation set on the upper end of each independent support. The self-built house is erected on the foundation. Each independent support includes an inner support column and an outer support sleeve. The outer support sleeve is fitted onto the inner support column, and the upper end of the outer support sleeve is connected to the foundation. Several vertically arranged high-strength elastic rubber rods are attached to the outer wall of the inner support column and are arranged around the circumference of the inner support column. The inner wall of the outer support sleeve is tightly fitted with the outer wall of each high-strength elastic rubber rod, and a gap is reserved between the inner wall of the outer support sleeve and the outer wall of the inner support column.

[0008] Specifically, a high-strength elastic rubber rod is installed between the outer support sleeve and the inner support column. The high-strength elastic rubber rod increases the friction between the outer support sleeve and the inner support column, allowing the outer support sleeve and the inner support column to move in opposite directions along the axis of the independent support when the upper and lower ends of the independent support are subjected to vibration and impact. This achieves the effect of energy dissipation and vibration reduction. Furthermore, the contact area between the high-strength elastic rubber rod and the outer support sleeve and the inner support column is guaranteed, ensuring the connection stability between the outer support sleeve and the inner support column. The combination of multiple independent supports can achieve the effect of stabilizing the support platform.

[0009] Furthermore, each of the inner support columns is provided with a base at its lower end, and the upper side of each base is shaped like a frustum. Each base has a limiting groove on its upper side. Each inner support column is fitted with a high-strength elastic rubber pad whose lower side is embedded in the limiting groove. The lower end face of each outer support sleeve is in close contact with the upper surface of the corresponding high-strength elastic rubber pad.

[0010] Specifically, the base increases the contact area between the inner support column and the bottom of the pit, ensuring the connection stability between the inner support column and the pit even with a small cross-sectional area. This ensures that the independent support can stably transmit pressure to the foundation, and the elastic rubber pad can provide buffering and sealing effects, further ensuring the connection stability and safety of the inner support column and the outer support sleeve.

[0011] Furthermore, each of the outer support sleeves is provided with a connecting seat at its upper end, and the lower side of each connecting seat is shaped like a frustum. The area of ​​the upper surface of the connecting seat is larger than the cross-sectional area of ​​the outer support sleeve. The outer support sleeve is a metal component, and the connecting seat is a reinforced concrete component. The outer support sleeve and the connecting seat are fixedly connected as a whole.

[0012] Specifically, the use of a connecting seat can increase the contact area between the outer support sleeve and the foundation, effectively increasing the connection stability between the outer support sleeve and the foundation. Furthermore, by setting the outer support sleeve as a metal component, the effectiveness of the outer support sleeve can be ensured even when the outer support sleeve has a low thickness.

[0013] Furthermore, the connecting seat includes a steel reinforcement cage, connecting steel bars, and a concrete pouring section. Several connecting steel bars are vertically arranged, and each connecting steel bar is welded to the inner wall of the outer support sleeve. The steel reinforcement cage is formed by binding several steel bars together. The concrete pouring section covers the upper end of the steel reinforcement cage and the outer support sleeve.

[0014] Specifically, by connecting the reinforcing bars, the connection strength and stability between the connecting seat and the outer support sleeve can be increased. The connecting seat, which is shaped like a frustum and is a reinforced concrete component, can be formed by using the reinforcing bar skeleton and the concrete pouring part.

[0015] Furthermore, the upper ends of the inner support columns all pass through the upper surface of the connecting seat, and each inner support column is fitted with an isolation ring on the part that passes through the connecting seat. The isolation ring is used to isolate the part of the inner support column that passes through the connecting seat from the foundation. The isolation ring is made of waterproof membrane.

[0016] Specifically, by having the upper end of the inner support column pass through the connecting seat and using an isolation ring to isolate the inner support column and the part extending out of the connecting seat from the foundation, it is possible to facilitate the observation of the settlement of the outer support sleeve. This allows for a quick and intuitive assessment of the foundation settlement during the construction of a self-built house.

[0017] Furthermore, both the inner support column and the outer support sleeve are arranged in a frustum shape. The upper end area of ​​the inner support column is smaller than the lower end area of ​​the inner support column. The outer wall of the inner support column is provided with several positioning grooves for embedding high-strength elastic rubber rods.

[0018] Specifically, by arranging the inner support column and the outer support sleeve in a frustum shape, the mating area between the inner support column and the outer support sleeve can be increased. At the same time, when the inner support column and the outer support sleeve are subjected to opposing forces, the force can be disassembled in the horizontal and vertical directions, making it easier for the inner support column and the outer support sleeve to recover after displacement and deformation.

[0019] Furthermore, the outer support sleeve also includes a number of reinforcing ribs equidistantly arranged around the axis of the outer support sleeve. Each reinforcing rib is triangular in shape, and one side of each reinforcing rib is welded to the outer wall of the outer support sleeve. The upper end of each reinforcing rib is embedded in the connecting seat.

[0020] Specifically, the strength of the outer support sleeve can be increased by reinforcing ribs, making it less prone to deformation when subjected to greater pressure, thus ensuring the safe use of the outer support sleeve.

[0021] Secondly, this application also provides a construction method for the aforementioned seismic-resistant structure of a building project, employing the following technical solution:

[0022] A construction method for seismic-resistant structures in building engineering includes the following steps:

[0023] S1. Clean up the site and level the ground, then excavate several foundation pits according to the plan;

[0024] S2. In each foundation pit, an independent support consisting of an inner support column, a high-strength elastic rubber rod, and an outer support sleeve is installed, and the upper end of each independent support extends beyond the ground.

[0025] S3. Backfill clay into each foundation pit, compact the ground, level the ground again, lay waterproof membrane on the ground, and build formwork around the site.

[0026] S4. Install the steel cage on site, and then pour concrete to form a foundation that is integrated with the outer support sleeve of each independent support.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Each independent support can individually achieve the effect of energy dissipation and shock absorption. It has fewer parts, higher stability, is easy to construct and use, and its service life can be guaranteed.

[0029] 2. During the construction of self-built houses, each independent support can measure the local settlement of the foundation, making it easier for construction workers to quickly detect problems such as tilting and settlement of the foundation due to uneven load-bearing.

[0037] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0038] Reference Figure 1 An earthquake-resistant structure for building construction, used as the foundation for self-built houses, includes several independent supports 1 and a foundation 2 set on the upper end of each independent support 1. The self-built house is built on the foundation 2. After the construction of the foundation 2 is completed, each independent support 1 has a portion extending beyond the upper surface of the foundation 2, and the portion of each independent support 1 extending beyond the upper surface of the foundation 2 can be raised and lowered relative to the foundation 2 to serve as a reference standard for the settlement of the foundation 2.

[0039] Reference Figure 2 Each independent support 1 includes an inner support column 11, an outer support sleeve 12, and a high-strength elastic rubber rod 13; wherein, refer to Figure 3 Several positioning grooves 111 are arranged circumferentially around the axis of the inner support column 11 on the outer wall of the inner support column 11. Several high-strength elastic rubber rods 13 are provided, and a portion of each high-strength elastic rubber rod 13 is embedded in each positioning groove 111, with a portion of each high-strength elastic rubber rod 13 located outside the inner support column 11. Inner and outer support sleeves 12 are fitted on the inner support column 11, and the inner wall of the outer support sleeve 12 is tightly fitted with the outer wall of each high-strength elastic rubber rod 13, with a gap reserved between the inner wall of the outer support sleeve 12 and the outer wall of the inner support column 11.

[0040] Reference Figure 2 and Figure 4 Each inner support column 11 is arranged in the shape of a frustum, and the upper end area of ​​the inner support column 11 is smaller than the lower end area of ​​the inner support column 11. Each inner support column 11 has a base 112 at its lower end. The upper side of each base 112 is arranged in the shape of a frustum or a frustum. Each base 112 has a limiting groove 113 on its upper side. Each inner support column 11 is fitted with a high-strength elastic rubber pad 114 whose lower side is embedded in the limiting groove 113. The lower end face of each outer support sleeve 12 is tightly fitted with the upper surface of the corresponding high-strength elastic rubber pad 114.

[0041] Reference Figure 2 and Figure 5Each outer support sleeve 12 is shaped like a frustum, and the area of ​​the upper end of the outer support sleeve 12 is smaller than the area of ​​the lower end of the outer support sleeve 12; wherein, each outer support sleeve 12 is provided with a connecting seat 121 at its upper end, and the lower side of each connecting seat 121 is shaped like a frustum or a frustum, and the area of ​​the upper surface of the connecting seat 121 is larger than the cross-sectional area of ​​the outer support sleeve 12.

[0042] Among them, reference Figure 5 The outer support sleeve 12 is a metal component. Specifically, the outer support sleeve 12 is formed by rolling up a steel plate with a thickness of 2.3cm-4.1cm. Several reinforcing ribs 122 are also provided on the outer support sleeve 12, which are equidistantly arranged around the axis of the outer support sleeve 12. Each reinforcing rib 122 is triangular in shape. One side of each reinforcing rib 122 is welded to the outer wall of the outer support sleeve 12. The upper end of each reinforcing rib 122 is embedded in the connecting seat 121.

[0043] Reference Figure 6 The connecting seat 121 is a reinforced concrete component. The connecting seat 121 includes a steel reinforcement cage 123, connecting steel bars 124 and a concrete pouring part 125. Several connecting steel bars 124 are vertically arranged, and each connecting steel bar 124 is welded to the inner wall of the outer support sleeve 12. The steel reinforcement cage 123 is formed by binding several steel bars. The concrete pouring part 125 covers the steel reinforcement cage 123 and the upper end of the outer support sleeve 12.

[0044] The upper ends of the inner support columns 11 all pass through the upper surface of the connecting seat 121. An isolation ring (not shown in the figure) is fitted on the part of each inner support column 11 that passes through the connecting seat 121. The isolation ring is used to isolate the part of the inner support column 11 that passes through the connecting seat 121 from the foundation 2. The isolation ring is made of waterproof membrane.

[0045] The implementation principle of this application embodiment is as follows:

[0046] A high-strength elastic rubber rod 13 is installed between the outer support sleeve 12 and the inner support column 11. This increases the friction between them, allowing the outer support sleeve 12 and the inner support column 11 to move in opposite directions along the axis of the independent support 1 when subjected to vibration and impact. This provides energy dissipation and vibration reduction. Furthermore, the contact area between the high-strength elastic rubber rod 13 and the outer support sleeve 12 and inner support column 11 is ensured, guaranteeing the connection stability between them. The combination of multiple independent supports 1 effectively stabilizes the foundation 2. By having the upper end of the inner support column 11 pass through the connecting seat 121 and using an isolation ring to isolate the inner support column 11 and its portion extending beyond the connecting seat 121 from the foundation 2, it is easier to observe the settlement of the outer support sleeve 12. This allows for quick and intuitive assessment of foundation 2 settlement during the construction of the self-built house.

[0050] S3. Backfill clay into each foundation pit, compact the ground, level the ground again, lay waterproof membrane on the ground, and build formwork around the site.

[0051] S4. Install the steel cage on site, and then pour concrete to form a foundation 2 that is connected to the outer support sleeve 12 of each independent support 1.
