technical field

The invention relates to the technical field of buildings, in particular to an earthquake-resistant low-rise building.

Background technique

The building structure is a skeleton structure formed by building components such as plates, beams, columns, walls, and foundations, which has certain spatial functions and can safely withstand various normal loads of the building.

The building system disclosed in the invention patent with application publication number CN105143575, its main technical solution is that the assembled second floor is raised, and the first floor is assembled on site below the second floor or moved to the second floor after the first floor is assembled Below, the second floor and the first floor are fixed to the ground by beams, which reduces the installation of scaffolding during the construction of this building. However, when the building is subjected to an earthquake, the foundation is prone to collapse, and the supporting columns or supporting beams are easy to fall from the roots. Fracture, the top of the building is easy to collapse, the overall building is easy to be damaged, and the internal skeleton structure is easy to crack and deform, and it is not easy to repair, resulting in a waste of cost and resources.

When an earthquake occurs, the spring can Absorb earthquake energy and protect the lower crossbar from damage. After the earthquake, the anchor block is fixed in the original position of the foundation, and the spring traction support frame returns to the original position;

3. Since the top frame and the support frame are connected by damping elements and elastic plates, when the building suffers an earthquake, the top frame shakes on the support frame, and the damping elements and elastic plates absorb most of the energy of the earthquake. The inter-shear stress is reduced, the top frame will not crack from the support frame, and the top of the building will not collapse. When the earthquake is over, the elastic plate pulls the top frame back to its original position;

4. Since there are damping elements connected between the upper and lower corresponding two connecting beams, when an earthquake occurs, the connecting beams are deformed before the "mouth" frame yields, and the damping elements absorb the seismic energy to protect the "mouth" frame from In the event of deformation, since the connecting beams are easy to replace and repair, the foundation skeleton will not be damaged, which protects the building and plays a good anti-seismic role.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 to 10, an earthquake-resistant low-rise building includes a building body 1 and a frame 2 arranged in the building body 1. The frame 2 includes a top frame 20 and a supporting frame 21. The top frame 20 includes a plurality of trusses 200 and connecting rods 201. The trusses 200 are vertical triangular frames. The front and rear adjacent trusses 200 are parallel and correspond to each other. Two adjacent trusses 200 are vertically connected with horizontal connecting rods. 201.

The support frame 21 is fixed on the bottom of the top frame 20, and the support frame 21 includes a plurality of damping elements 210, a "mouth" frame 211 and a connecting beam 212, and the damping element 210 is a horizontal rectangular plate, the "Mouth" frame 211 comprises upper and lower crossbars and left and right uprights, and the top of described upper crossbar is fixed with damping element 210, and the top of damping element 210 is fixed on truss 200 bottoms, and the top of described left and right uprights Elastic plates 4 are respectively fixed, and the top of the elastic plates 4 is fixed on the bottom of the truss 200, and the bottoms of the left and right columns are respectively provided with rectangular mounting blocks 5, and the external cover of the mounting blocks 5 is covered with a storage box 6, and the storage box 6 It is a box with an opening on the upper surface, an elastic backing plate 60 is fixed on the inner wall of the box, the storage box 6 is anchored in the foundation 9, the bottom of the lower cross bar is respectively fixed with springs 7 near the left and right ends, and the bottom of the spring 7 is fixed with anchors. The block 8 and the spring 7 are installed in the through hole of the foundation 9, and the anchor block 8 is anchored in the foundation 9.

Two horizontal connecting beams 212 are vertically connected between the front and rear adjacent "mouth" shaped frames 211 near the left and right ends respectively. In the upper part, a damping element 210 is connected between the two corresponding upper and lower connecting beams 212 .

At least three connecting rods 201 are connected between two adjacent trusses 200 .

The damping element 210 has a three-layer structure, which is an upper layer, a lower layer and a middle layer in sequence, the upper layer and the lower layer are both steel plates, and the middle layer is a rubber layer.

The elastic plate 4 is a three-layer structure, which is an upper layer, a lower layer and an intermediate layer in sequence. The upper layer and the lower layer are steel plates, and the intermediate layer is a board body with a wave-shaped cross section. The three-layer board is fixed by screws.

The cross-sectional area of the mounting block 5 is larger than that of the column.

The elastic backing plate 60 in the storage box 6 is close to the installation block 5 , specifically, the elastic backing plate 60 is an elastic rubber plate.

Because the mounting block 5 on the column is covered with a storage box 6, the box inner wall is fixed with an elastic backing plate 60. When the building suffered an earthquake, the column shook in the storage box 6, collided with the elastic backing plate 60, and the elastic backing plate 60 By absorbing most of the energy generated by the earthquake, the earthquake impact on the column is reduced, the column is not easy to break, the foundation is not easy to collapse, and the building is not easy to be damaged.

Since the bottom of the lower cross bar is fixed with springs 7 near the left and right ends respectively, the bottom of the springs 7 is fixed with an anchor block 8, the spring 7 is worn in the through hole of the foundation 9, and the anchor block 8 is anchored in the foundation 9. During an earthquake, the spring 7 can absorb the seismic energy and protect the upper rail from damage. After the earthquake, the anchor block 8 is fixed on the original position of the foundation, and the spring 7 pulls the support frame 21 to return to its original position.

Because the top frame 20 and the support frame 21 are connected by the damping element 210 and the elastic plate 4, when the building is subjected to an earthquake, the top frame 20 shakes on the support frame 21, and the damping element 210 and the elastic plate 4 absorb most of the energy of the earthquake, The shear stress between the top frame 20 and the support frame 21 is reduced, the top frame 20 will not split from the support frame 21, and the top of the building will not collapse. When the earthquake is over, the elastic plate 4 pulls the top frame 20 back to its original position .

Since there is a damping element 210 connected between the upper and lower corresponding two connecting beams 212, when an earthquake occurs, the connecting beam 212 yields and deforms before the "mouth" frame 211, and the damping element 210 absorbs the seismic energy to protect the "mouth". The shape frame 211 does not deform, and because the connecting beam 212 is easy to replace and repair, the basic skeleton will not be damaged, which protects the building and plays a good anti-seismic effect.

The specific implementation of the present invention has been described in detail above in conjunction with the accompanying drawings. However, the above description is not a limitation to the invention. Within the scope of disclosure that does not violate the spirit of the present invention, any technical solution of the invention is equivalent or equivalent. Effective deformation or replacement all belong to the protection scope of the present invention.
