Description

Technical Field

[0001] The present invention belongs to the technical field of seismic devices, and particularly relates to a seismic device for brick-concrete structure buildings. Background Art

[0002] The total floor area of existing urban and rural buildings in China exceeds 50 billion square meters, and the proportion of brick-concrete structure buildings with brick masonry walls as the main load-bearing and seismic walls is relatively large. Generally speaking, brick masonry materials have relatively low tensile and shear strengths, while the compressive strength is relatively high. They are characterized by a large self-weight, poor integrity, and easy brittle failure, resulting in poor seismic performance. Under strong earthquake actions, they are prone to serious damage or collapse, leading to a large number of casualties. During the Wenchuan earthquake and Yushu earthquake, a large number of brick-concrete structure houses collapsed, causing heavy losses. Therefore, in order to improve the integrity of the structures of rural buildings, seismic devices are installed inside or outside a large number of existing brick-concrete structure buildings that do not meet the seismic fortification requirements, so as to improve the integrity and seismic performance of rural buildings.

[0003] Chinese Utility Model Patent with the publication number of "CN216616347U" discloses a civil engineering shock absorption device, and its technical solution is as follows: The present invention discloses a civil engineering shock absorption device, which is composed of a front support shock absorption frame, a rear support shock absorption frame, a left support shock absorption frame, and a right support shock absorption frame connected and combined at the ends to form a box-shaped support structure. The top frame and the bottom frame are connected by a first buffer mechanism and a second buffer mechanism. The first buffer mechanism includes a top rod and a buffer cylinder, wherein the first buffer mechanism is located at the upper and lower supports at both ends of the top frame and the bottom frame, and the second buffer mechanism is located in the middle of the top frame and the bottom frame and is cross-supported. The present invention has a clever concept, a compact structure, a large supporting force, strong reliability, and remarkable buffer and shock absorption effects. It can be widely used in civil engineering, especially for shock absorption, earthquake prevention, and seismic resistance in building house foundations, bridge bearings, and the bases of vibrating equipment, so as to avoid damage to civil engineering structures.

[0004] Although this utility model can realize the support and earthquake prevention of rural buildings, during the construction process, it is necessary to cut materials according to the specific dimensions of rural buildings, and the operation and construction are relatively laborious and difficult. The cutting during material cutting will generate a large amount of dust at the construction site, affecting the physical health of construction workers. At the same time, the structure is not easy to change, and the adaptability to buildings is relatively low. When the rural buildings that have been reinforced are demolished, the demolition of the components of the seismic device used for the rural buildings is relatively difficult, and the reuse rate of the demolished components is relatively low.

Multiple spring holes and two side grooves are formed in the fixing frame. Elastic springs are fixedly connected in the multiple spring holes, and the multiple elastic springs are fixedly connected to a fixing piece. Two side plates are fixedly connected to the fixing piece, and the two side plates are respectively slidably fitted in the side grooves. When the building generates a horizontal displacement due to an earthquake, the elastic springs use their own elasticity to provide a force in the opposite direction to support the building and reduce the impact of the earthquake force on the building.

[0037] The first square rod 22 and the second square rod 3 are cross-connected in an X shape, and an upper telescopic assembly 29 and a lower telescopic assembly 30 are respectively connected to the upper and lower ends. The left and right sides of the adjusting device are fixedly connected through a connecting device; a sliding adjustment opening 33 is formed in the connecting device. When the upper telescopic assembly 29 and the lower telescopic assembly 30 extend to both sides to adapt to the size of the building, the two ends of the first square rod 2 and the second square rod 3 slide in cooperation with the sliding adjustment opening 33, and the heights on both sides change accordingly. When erected around the building, according to the size of the building, the operator adjusts the angle between the first square rod 2 and the second square rod 3 in the adjusting device, and pulls the upper telescopic assembly 29 and the lower telescopic assembly 30 to both sides to adapt to the size of the building. The two ends of the first square rod 2 and the second square rod 3 slide in cooperation with the sliding adjustment opening 33, and the heights on both sides change accordingly. During this process, after the upper spring 14 and the lower spring 18 arranged in the upper strip hole 12 and the lower strip hole 16 are squeezed, they provide a force in the opposite direction to the arc-shaped upper end strip 13 and the arc-shaped lower end strip 17 on both sides, and further provide a force in the lateral direction to the upper sliding rod 11 and the lower sliding rod 15, realizing the matching of the seismic device of the rural building and the rural building during enclosure, strengthening the fixation of the forms of the first square rod 2, the second square rod 3, the upper sliding rod 11, and the lower sliding rod 15, and facilitating the construction of the basic structure of the device.

[0038] An elastic telescopic assembly capable of telescoping in the horizontal direction is arranged in the upper telescopic assembly 29 and the lower telescopic assembly 30. The lower telescopic assembly 30 is further provided with a mounting hole position 32. The inner sides of the first connecting piece 1 and the second connecting piece 31 are connected with a fixing frame 21. The inner side of the fixing frame 21 is connected with a fixing piece 23 through an elastic spring 22. The side of the fixing piece 23 is connected with a side plate 24. The fixing frame 21 is provided with a side groove along the movement direction of the side plate 24. The fixing piece 23 is in direct contact with the building wall. When the building is shaken, the fixing piece 23 is squeezed, and the side plate 24 can move in the side groove.

[0039] The first connecting piece 1 and the second connecting piece 31 are respectively connected in the horizontal direction and the vertical direction through a middle connecting rod 9 and a corner rod 10. When horizontal connection needs to be realized between two adjusting devices, the second connecting piece 31 of the left adjusting device is fixed to the left side of the middle connecting rod 9 through a bolt, and the first connecting piece 1 of the right adjusting device is fixed to the right side of the middle connecting rod 9 through a bolt. The two adjusting devices are horizontally connected through the middle connecting rod 9; when vertical connection needs to be realized between two adjusting devices, the connecting pieces on both sides of the two adjusting devices close to the vertical angle are respectively fixed to the left and right sides of the corner rod 10 through bolts to realize vertical connection, strengthening the adaptability with the brick-concrete structure building, and thus realizing the tight hoop on the brick-concrete structure building.

[0040] The elastic telescopic component further includes an upper sliding rod 11 and a lower sliding rod 15.

[0041] Seismic devices are fixedly connected to both the first connecting piece 1 and the second connecting piece 31. The seismic device includes a fixing frame 21. A side groove is formed on the right side of the middle section of the fixing frame 21. Multiple spring holes and two side grooves are formed on the fixing frame. Elastic springs 22 are fixedly connected in the multiple spring holes. A fixing piece 23 is fixedly connected to the multiple elastic springs 22. Two side plates 24 are fixedly connected to the fixing piece 23. The two side plates 24 are respectively slidably engaged in the side grooves. When the building generates a horizontal displacement due to an earthquake, the elastic springs 22 utilize their own elasticity to provide a force in the opposite direction to support the building and reduce the impact of the seismic force on the building. During this process, the fixing frame 21 with a side groove on the right side of the middle section and in a "concave" shape, and the "convex" shaped component composed of the fixing piece 23 and the side plates 24 cooperate to slide when receiving the acting force of the elastic springs 22.

The operation and construction are relatively time-saving and labor-saving, improving the project efficiency.

[0043] The upper and lower sides of the first connecting piece 1 and the second connecting piece 31 are respectively provided with sliding adjustment openings 33. A screw 8 is arranged in the sliding adjustment opening 33, and a retaining piece 25 is arranged on the screw 8.

[0044] The upper and lower ends of the first square rod 2 and the second square rod 3 are respectively provided with a first upper shaft cylinder 4 and a first lower shaft cylinder 5, a second upper shaft cylinder 6 and a second lower shaft cylinder 7. During erection, since the upper sliding rod 11 and the lower sliding rod 15 need to be pulled to both sides to adapt to the size of the building, the angle between the first square rod 2 and the second square rod 3 will change accordingly. The first upper shaft cylinder 4 and the first lower shaft cylinder 5, the second upper shaft cylinder 6 and the second lower shaft cylinder 7 on the first square rod 2 and the second square rod 3 slide in the sliding adjustment opening 33, facilitating the adjusting device to adapt to the size of the building and increasing the fastening degree between the device and the brick-concrete structure building.

[0045] On the side where the first square rod 2 and the second square rod 3 are in contact with each other, an auxiliary installation notch 28 is provided. During erection, since the upper sliding rod 11 and the lower sliding rod 15 need to be pulled to both sides to adapt to the size of the building, the angle between the first square rod 2 and the second square rod 3 will change accordingly. The existence of the auxiliary installation notch 28 makes the connection between the first square rod 2 and the second square rod 3 more fitting. At the same time, due to the existence of the notch, the square rod can only move within a limited range. When the bolt drops due to a major earthquake, the square rod can be supported, extending the escape time for the people in the building.

[0046] The top and bottom of the arc-shaped upper end bar 13 and the arc-shaped lower end bar 17 are respectively connected with a limiting end plate 26. During erection, according to the size of the building, the operator adjusts the angle between the first square rod 2 and the second square rod 3 in the adjusting device, and pulls the upper telescopic assembly 29 and the lower telescopic assembly 30 to both sides to adapt to the size of the building. The two ends of the first square rod 2 and the second square rod 3 slide in cooperation in the sliding adjustment opening 33, and the heights on both sides change accordingly. During this process, the limiting end plate 26 guides the arc-shaped upper end bar 13 and the arc-shaped lower end bar 17 to slide smoothly in the upper strip hole 12 and the lower strip hole 16 with the compression of the upper spring 14 and the lower spring 18.

[0047] The bottom end of the second fixed ear 20 is connected with a leveling piece 27, and the bottom end of the leveling piece 27 is flush with the bottom end of the limiting end plate 26 at the bottom end of the arc-shaped lower end bar 17. When connecting to the ground, it is convenient for leveling with the ground, enabling the entire device to be vertically installed with the ground and avoiding aggravating the harm to the building during an earthquake due to the inclination of the device.
