Description

Technical Field

[0001] The utility model relates to the technical field of building foundations, in particular to an earthquake-resistant building foundation. Background Art

[0002] The foundation refers to the soil or rock mass that supports the foundation of the building, which can be divided into two categories: natural foundation and artificial foundation. Natural foundation does not require artificial reinforcement; artificial foundation needs artificial reinforcement.

[0003] Most of the existing buildings first dig a foundation pit, then compact the foundation pit, and then build a pyramid-shaped stepped building foundation. However, although this method has good stability, it has poor earthquake resistance and is only suitable for plain areas; and many building structures will choose to use spring shock absorption to resist earthquakes. For example, the patent document CN216664245U discloses an earthquake-resistant building foundation structure that resists earthquakes by evenly distributing springs between two layers of mounting plates. However, it should be understood that the spring has a certain fatigue strength. When the number of elastic deformations exceeds a certain range, the spring elastic fatigue will cause the foundation to sink, thereby affecting the strength of the foundation; and even if the spring can buffer the vibration, it does not have a good effect on preventing the building from tilting during an earthquake.

[0004] To this end, the utility model provides an earthquake-resistant building foundation to improve the earthquake-resistant stability of the foundation. Utility Model Content

[0005] The utility model aims to solve the problems existing in the prior art and proposes an earthquake-resistant building foundation.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Preferably, the reinforcing plates on both sides of the bottom end of the first mounting plate are arc-shaped plates in an eight-shaped shape.

[0009] Preferably, a reinforcement layer is provided on the inner wall of the foundation pit.

[0010] Preferably, a waterproof layer is provided between the reinforcement layer and the inner wall of the foundation pit.

[0013] Compared with the prior art, the utility model provides an earthquake-resistant building foundation, which has the following beneficial effects:

[0014] 1. The pile foundation formed by pouring is used to anchor the whole structure. Several second mounting plates are spliced ​​with the first mounting plate through connecting anchors to form a stable frame to firmly support the building body, so that the strength of the upper part of the foundation is enhanced, thereby improving the stability of the building; and two rows of reinforcement plates are symmetrically arranged at the bottom end of the first mounting plate, and the reinforcement plates extend downward into the foundation pit in a dispersed manner, which not only improves the grip of the first mounting plate, but also increases the left and right protection capabilities of the first mounting plate 3, thereby improving the anti-tilt performance of the first mounting plate, so that the whole structure has good seismic resistance.

[0015] 2. A reinforcement cage is provided in the area below the first mounting plate in the foundation pit, which is staggered with the reinforcement plate.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0025] Embodiment 1, in order to solve the problems existing in the prior art, this embodiment provides an earthquake-resistant building foundation, including a foundation pit 1 excavated on the ground, and a reinforcement layer 11 is provided on the inner wall of the foundation pit 1 to maintain the shape of the foundation pit 1, play a role in wall protection, and reinforce the foundation pit 1;

[0026] A platform 2 is provided in the foundation pit 1, on which a first mounting plate 3 is placed, and a building body 4 is installed at the center of the end face of the first mounting plate 3. Steps are provided on both sides of the bottom of the building body 4, and a number of second mounting plates 5 are overlapped on the steps on both sides. Reinforcing ribs 6 are provided between the two corresponding second mounting plates 5 on both sides of the building body 4. There are holes drilled on the building body 4 so that the reinforcing ribs 6 penetrate the building body 4, thereby forming the second mounting plates 5 on both sides and the building body 4 into one body; and connecting anchors 7 are provided between the second mounting plates 5 and the first mounting plates 3, thereby assembling the second mounting plates 5 and the first mounting plates 3 together. The building body 4 is reinforced by splicing the first mounting plates 3 and the second mounting plates 5 into a frame to improve the stability of the foundation. The bottom end of the first mounting plate 3 is symmetrically provided with a number of reinforcing plates 8, which extend into the depth of the foundation pit 1, thereby deepening the grip of the first mounting plate 3, and the reinforcing plates 8 on both sides are distributed in an eight-shaped shape, which not only further improves the stability of the building, but also improves the ability of the building body 4 to prevent tilting from left to right, and improves the anti-seismic anti-tilting ability.

[0027] The rest of the space in the foundation pit 1 is filled with pile foundations 10, which are cast by mixing concrete and other materials. A notch for casting is provided on the side of the first mounting plate 3, and the first mounting plate 3 and the reinforcement plate 8 are fastened in the foundation pit 1 by the pile foundations 10;

[0028] A plurality of reinforcing cages 9 tied with earthquake-resistant steel bars are arranged at intervals at the bottom end of the foundation pit 1. The plurality of reinforcing cages 9 and a plurality of reinforcing plates 8 are staggeredly distributed along the length direction of the building body 4, and the reinforcing cages 9 are against the bottom surface of the first mounting plate 3. The strength of the pile foundation 10 is increased by reinforcing the cages 9, thereby improving the earthquake resistance and deformation resistance of the foundation.

[0029] The specific use process of this embodiment is as follows:

[0030] The pile foundation 10 formed by pouring is used to anchor the whole. The first mounting plate 3 is immersed in the pile foundation 10, and a number of second mounting plates 5 are embedded in the pile foundation 10. The second mounting plates 5 are spliced ​​with the first mounting plate 3 through the connecting anchors 7, so as to form a stable frame to firmly support the building body 4, so that the strength of the upper part of the foundation is enhanced, thereby improving the stability of the building; and two rows of reinforcing plates 8 are symmetrically arranged at the bottom end of the first mounting plate 3, and the reinforcing plates 8 extend into the pile foundation 10 cast in the foundation pit 1, so as to improve the grip of the first mounting plate 3, and the reinforcing plates 8 are buckled in the pile foundation 10 in an eight-shaped shape, which increases the left and right protection capabilities of the first mounting plate 3, and then improves the anti-tilt performance of the first mounting plate 3, so that the whole has good seismic resistance.

[0031] The area below the first mounting plate 3 in the foundation pit 1 is provided with a reinforcing cage 9 staggered with the reinforcing plate 8. The reinforcing cage 9 improves the strength of the lower part of the foundation, thereby improving the bearing capacity of the foundation and improving the overall seismic performance of the foundation.

[0032] In Example 2, the reinforcing plates 8 on both sides of the bottom end of the first mounting plate 3 are both arc-shaped plates, which improve the gripping force between the reinforcing plates 8 and the pile foundation 10, so that the first mounting plate 3 is more tightly connected to the lower part of the pile foundation 10. At the same time, the arc-shaped structure also increases the contact area, resulting in a better anti-tilt effect.

[0033] Embodiment 3: A waterproof layer is provided between the reinforcement layer 11 and the inner wall of the foundation pit 1 to prevent the foundation pit 1 from water seepage and collapse.
