Description

Technical Field

[0001] The utility model belongs to the field of building supports, and in particular relates to a building support capable of resisting earthquake shear waves. Background Art

[0002] Earthquakes are natural disasters with great destructive power. The shock waves generated by earthquakes are divided into transverse waves and longitudinal waves. Transverse waves will produce lateral shear force on buildings, which can easily cause buildings to collapse and cause serious disasters.

[0003] Therefore, reducing the impact of shear waves on buildings is an important means to reduce the losses caused by earthquake disasters. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a building support that is resistant to earthquake shear waves, so as to reduce the impact of earthquake shear waves on buildings, thereby reducing the damage caused by earthquakes.

[0005] The technical solution of this utility model is as follows:

[0006] A building support for resisting seismic shear waves, comprising a vertical buffer plate 7 parallel to the building outer wall 9 and two parallel upper and lower horizontal plates, characterized in that: the buffer plate 7 is fixed on the ground 11, and a buffer material 8 is arranged between the buffer plate 7 and the building outer wall 9, and a number of support columns are arranged between the upper horizontal plate 1 and the lower horizontal plate 2; the support column is divided into an upper movable section 3 and a lower fixed section 4; the movable section 3 is fixedly connected to the upper horizontal plate 1, and the fixed section 4 is fixedly connected to the lower horizontal plate 2; a fixed steel core 5 is arranged at the center of the support column, and the fixed steel core 5 is divided into a thick section 5-1 in the upper half and a thin section 5-2 in the lower half, and the thin section 5-2 is fixedly connected to the fixed section 4, the upper part slightly protrudes from the upper bottom surface of the fixed section 4, and the lower part protrudes from the lower horizontal plate 2 and is fixedly connected to the foundation; two slots with different diameters are opened in the center of the movable section 3, and the diameters of the two slots are slightly larger than the thick section 5-1 and the thin section 5-2 of the fixed steel core 5, respectively.

[0007] Furthermore, the contact surface between the movable section 3 and the fixed section 4 of the support column is provided with a groove for storing lubricating grease.

[0008] Furthermore, a sealing sleeve 6 is wrapped around the outside of the support column.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] First, when the earthquake shear wave arrives, the fixed section 4 of the support column will move laterally with the earth. Under the action of lubricating grease, the movable section 3 of the support column and the upper building part will remain relatively still under the influence of inertia, thereby reducing the impact of the earthquake shear wave on the building part.

[0011] Secondly, the upper transverse plate 1 and the lower transverse plate 2 are provided to ensure that the entire structure moves laterally when affected by earthquake shear waves, thereby preventing damage to various parts of the building due to uneven force.

[0012] Third, the buffer material 8 is filled between the buffer plate 7 and the building outer wall 9, which can further reduce the lateral movement of the building. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 and Figure 2 , a building support for resisting earthquake shear waves, comprising a vertical buffer plate 7 parallel to the building outer wall 9 and an upper horizontal plate 1 and a lower horizontal plate 2 parallel to each other, the buffer plate 7 being fixed to the ground 10, and a buffer material 8 (such as a spring) being provided between the buffer plate 7 and the building outer wall 9 for buffering; a plurality of support columns are provided between the upper horizontal plate 1 and the lower horizontal plate 2, the support columns being divided into a movable section 3 fixedly connected to the upper horizontal plate 1, and a fixed section 4 fixedly connected to the lower horizontal plate 2, a fixed steel core 5 being provided at the center of the support column, and the fixed steel core 5 being divided into an upper half section The thick section 5-1 is fixedly connected to the thin section 5-2 of the lower half, and the thin section 5-2 is fixedly connected to the fixed section 4. The upper part slightly extends beyond the upper bottom surface of the fixed section 4, and the lower part extends beyond the lower cross plate 2 and is fixedly connected to the foundation; two slots with different diameters are opened in the center of the movable section 3, and the diameters of the two slots are slightly larger than the thick section 5-1 and the thin section 5-2 of the fixed steel core 5; the contact surfaces of the movable section 3 and the fixed section 4 are opened with grooves for storing lubricating grease, wherein the groove on the movable section 3 is an annular groove 3-1, and the grooves on the fixed section 4 are several rectangular grooves 4-1.

[0018] The purpose of this design is: when the shear wave of an earthquake arrives, the foundation vibrates laterally, which will drive the lower cross plate 2, the fixed section 4 and the fixed steel core 5 to vibrate laterally. Since the contact surface of the fixed section 4 and the movable section 3 is provided with a rectangular groove 4-1 and an annular groove 3-1, and grease is filled in the groove, the friction is small. The part above the movable section 3 is affected by inertia, and the movable section 3 and the fixed section 4 will move relative to each other, thereby reducing the amplitude of the lateral vibration and keeping the building as a whole relatively still; the fixed steel core 5 avoids the problem of misalignment between the movable section 3 and the fixed section 4 when the amplitude is large. At the same time, the diameter of the two slots in the movable section 3 is slightly larger than the diameter of the thick section 5-1 and the thin section 5-2 of the fixed steel core 5. Therefore, the fixed steel core 5 has a certain lateral movement space inside the movable section 3, avoiding the vibration being directly transmitted to the movable section 3; the upper and lower cross plates 2 ensure uniform lateral vibration transmission, avoiding the problem of damage caused by local uneven force; the buffer plate 7 and the buffer material 8 further buffer the building's exterior wall 9, and at the same time prevent the wall from collapsing due to uneven force.

[0019] A sealing sleeve 6 is provided outside the support column, the purpose of which is to further prevent the movable section 3 and the fixed section 4 from being dislocated due to large-amplitude lateral vibration, and at the same time to seal the grease and reduce grease loss.

[0020] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
