Description

Technical Field

[0001] The invention relates to the field of earthquake-resistant building technology, specifically, to an earthquake-resistant building pile foundation. Background Art

[0002] A deep foundation consisting of a pile and a pile cap connected to the top of the pile, or a single pile foundation connected by a column and a pile foundation, is referred to as a pile foundation. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. Building pile foundations are usually low cap pile foundations.

[0003] Since mountainous areas are often prone to earthquakes, the requirements for earthquake resistance of pile foundations are quite high. Generally, during an earthquake, the vibration is transmitted to the main body of the building, causing damage to the connection between the horizontal beams and longitudinal beams of the main body of the building, thus causing damage to the building.

[0009] Furthermore, the longitudinal shock-absorbing device includes a connecting sleeve located in the middle of the pedestal, a fixing pile is provided in the middle of the connecting sleeve, a cavity is provided inside the fixing pile, and a shock-absorbing plate is provided in the middle of the cavity, a plurality of evenly distributed guide devices are provided on the inner wall of the connecting sleeve, and a shock-absorbing column is provided in the middle of the connecting sleeve.

[0010] Furthermore, the guide device includes a trapezoidal fixing rod connected to the connecting sleeve, a guide shaft is provided on the side of the trapezoidal fixing rod away from the connecting sleeve, the lower end of the guide shaft is sleeved with a guide tube connected to the fixing pile, and the lower end of the guide shaft passes through the fixing pile and is connected to the shock-absorbing plate inside the cavity, and the guide shaft and the guide tube cooperate closely with each other.

[0011] Furthermore, the shock-absorbing column includes a first fixed plate connected to the fixed pile, a plurality of circular corrugated plates are arranged on the upper end of the first fixed plate, a supporting clamping plate with the same diameter as the circular corrugated plates is arranged between the two circular corrugated plates, a second fixed plate connected to the connecting sleeve is arranged on the upper end of the circular corrugated plate, and a plurality of evenly distributed telescopic rods connected to the second fixed plate are arranged on the upper end of the first fixed plate.

[0012] Furthermore, the metal corrugated plate and the circular corrugated plate are both made of metal with high toughness and good elasticity, and the wave crests of two adjacent circular corrugated plates are arranged relative to each other.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The building is supported by prefabricated fixed plates and pedestals, the stability and safety of the building are improved by positioning the foundation piles, and the lateral tearing force of the vibration on the building is reduced by the setting of the lateral shock-absorbing blocks during an earthquake, thereby achieving the effect of earthquake-resistant protection of the building. The longitudinal shock-absorbing device is installed between the pedestal by the setting of the positioning groove, and the longitudinal vibration of the building is alleviated by the setting of the longitudinal shock-absorbing device during an earthquake, thereby achieving the effect of earthquake-resistant protection of the building. When the prefabricated cylinder is installed, concrete is injected into the interior thereof, so that the conical pile moves downward, so that the fixing groove nails penetrate into the soil layer at the bottom, thereby achieving the purpose of fixing the pile foundation, and the fixed wing moves outward through the guide groove through the movement of the conical pile, so that the fixed wing penetrates into the soil layer on the side of the pile foundation, thereby further fixing the impact, and the lower end of the fixed wing is set as a plane to increase the support area between it and the soil layer, thereby preventing the device from sinking.

[0015] 2. The arrangement of the prefabricated concrete parts including the prefabricated cylinder, the fixed wing, the conical pile and the fixed groove nail facilitates the rapid installation of the device. During the installation, concrete is injected into the prefabricated cylinder to mix with the other prefabricated parts, thereby fixing the prefabricated parts and improving the stability of the device. The arrangement of the fixed wing with a certain taper facilitates the penetration of the fixed wing into the middle of the soil layer, thereby achieving the fixing effect. The arrangement of the concave fixing plate cooperates with the convex block and cooperates with the arrangement of the guide slider, so that the lateral vibration force generated when an earthquake occurs is transmitted through the metal corrugated plate to absorb the internal vibration, thereby achieving the purpose of alleviating the vibration, making it difficult for the vibration to be directly transmitted to the middle of the building to cause damage to the building, thereby achieving the purpose of earthquake resistance.

[0016] 3. The purpose of alleviating vibration is achieved through the setting of the connecting sleeve and the fixed pile through the upward and downward activities of the two and the cooperation of the shock-absorbing column, thereby achieving the purpose of shock reduction and earthquake resistance. The cooperation of the shock-absorbing plate and the guide device makes there exist air pressure differences inside the cavity, thereby cooperating with the setting of the shock-absorbing column to achieve the effect of reducing vibration. The guide shaft is fixed by the setting of the trapezoidal fixing rod. The setting of the guide shaft and the setting of the guide tube form a complete telescopic state between the connecting sleeve and the fixed pile. When the vibration is transmitted, the air inside the cavity is continuously vibrated by the shock-absorbing plate connected to the guide shaft, so that the gas inside the cavity is continuously squeezed, thereby achieving the purpose of shock reduction. The purpose of installing the circular wave plate is achieved through the mutual cooperation between the first fixed plate and the second fixed plate. The setting of the circular wave plate facilitates the absorption of vibration when transmitting vibration, thereby achieving the purpose of earthquake resistance. The setting of the circular wave plates with staggered arrangement improves the stability of the shock-absorbing column. BRIEF DESCRIPTION OF THE DRAWINGS
