Problems solved by technology

[0003] Due to the wide use of light houses, it is often necessary to set the raft foundation of light houses on complex terrain. The existing raft foundation cannot adapt to the complex terrain environment, such as being built on a ground with a certain inclination. Or when the ground subsides, it is easy to cause potential safety hazards; in addition, the raft foundations of light houses in the prior art do not usually have seismic design. The interior is reinforced, and it is easy to affect the use and aesthetics of the building

Embodiment 1

[0032] Such as Figure 1-Figure 6 As shown, the present embodiment discloses a raft foundation for complex terrain, including a first bottom plate 1, on the bottom wall of the first bottom plate 1, several positioning grooves 11 (such as Figure 5 As shown), the positioning grooves 11 are all cuboid and distributed in a rectangular array; pile foundations 12 are arranged outside the four corners of the positioning grooves 11, and the tops of the pile foundations 12 are all It is fixedly connected with the bottom of the first bottom plate 1; buffer airbags 2 are provided at the lower part of the positioning groove 11, and the buffer airbags 2 are cuboid in shape; convex airbags are connected at the top of the buffer airbags 2 21, the shape of the raised airbag 21 corresponds to the shape of the positioning groove 11, and the raised airbag 21 is movably installed in the positioning groove 11; According to the support columns 13 distributed in a rectangular array, a shock absorb...

Embodiment 2

[0036] Such as Figure 6 As shown, in this embodiment, on the basis of Embodiment 1, positioning slots 22 are provided at the four corners of the buffer airbag 2, and the shape of the positioning slots 22 corresponds to the shape of the pile foundation 12. . When the cushioning airbag 2 is deformed under pressure, the positioning slots 22 at the four corners are in contact with the corresponding pile foundations 12 and can be stuck together, so that the cushioning airbag 2 can be positioned through the pile foundations 12 , to reduce the large displacement of the buffer airbag 2 due to deformation at the lower part of the first bottom plate 1 .

Embodiment 3

[0038] Such as Figure 7 As shown, this embodiment is based on Embodiment 1, and the buffer airbag 2 is sequentially composed of a styrene-butadiene rubber layer 23 , a nylon layer 24 and a butyl rubber layer 25 from outside to inside. The styrene-butadiene rubber layer 23 has the characteristics of wear resistance, aging resistance and water resistance, and has a high surface friction coefficient, which can improve the wear resistance and service life of the buffer airbag 2 . The nylon layer 24 has characteristics of impact resistance, fatigue resistance and tensile resistance, and can play a role in supporting the cushioning airbag 2 . The butyl rubber layer 25 has good airtightness and aging resistance, and is used to form an airtight layer so that the buffer airbag 2 has sufficient airtightness.

Abstract

The invention discloses a raft foundation for complex terrains. The comprises a first bottom plate, a plurality of positioning grooves are formed in the bottom wall of the first bottom plate, and pilefoundations are arranged on the outer sides of the four corners of each positioning groove; buffering air bags are arranged on the lower portions of the positioning grooves and are each in a cuboid shape; the upper portions of the buffering air bags are connected with protruding air bags; a plurality of supporting columns and shock pads which are distributed according to a rectangular array are arranged on the top wall of the first bottom plate; and a second bottom plate is arranged at the upper part of the first bottom plate. The raft foundation for the complex terrain can adapt to the complex terrain environment, displacement and stress generated by ground subsidence can be dispersed, and the construction and use safety of a light house is improved; besides, transmission of earthquake vibration to an upper building structure can be effectively reduced, so that the light house has certain earthquake resistance, and reinforcement outside and inside the light house is not needed.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a raft foundation for complex terrain. Background technique [0002] With the development of the economy and the advancement of technology, light houses for temporary or short-term use are becoming more and more popular and widely used and built. Light houses are prefabricated buildings, which have the advantages of standardized production and assembled construction, and have the characteristics of quick disassembly and reusability, which can meet the needs of various groups, such as outdoor sports houses, temporary commercial buildings, short-term dormitories on construction sites , army training barracks, etc., so it has broad market prospects. The light houses of the prior art have certain deficiencies in the process of construction and use: [0003] Due to the wide use of light houses, it is often necessary to set the raft foundation of light houses on complex terrain....
