Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to an anti-collision device for a building structure. Background Art

[0002] When constructing a building structure at a construction site, seismic joints are usually opened or reserved between a group of adjacent building structures, and anti-collision devices are embedded inside the seismic joints to cope with the vibrations generated during an earthquake, which may cause the walls on both sides of the seismic joints to approach each other and collide when the vibration occurs.

[0003] Existing anti-collision devices usually use high-toughness memory alloy steel plates installed inside the seismic joints and fixed to the walls of the buildings on both sides with bolts. When an earthquake or strong wind occurs, the plates between the walls of the buildings on both sides will be squeezed or stretched, thereby acting as a spacing for the buildings on both sides.

[0004] However, the above-mentioned existing anti-collision devices have limitations. Specifically, when more severe disasters or weather conditions occur, the higher parts of the building will shake more frequently and with greater amplitude than the parts of the building close to the foundation. The device will produce deformation fatigue when frequently squeezed or stretched, causing damage to the internal structure of the device's material. The degree of damage is difficult to observe with the naked eye, posing a safety hazard and increasing the probability of subsequent fractures. Utility Model Content

[0009] Preferably, the outer diameter of the connecting column is half the size of the inner diameter of the opening of the cylinder.

[0010] Preferably, the connecting column is fixedly connected to the fixing plate through a flange and high-strength bolts.

[0027] refer to Figure 1 and Figure 2 The utility model provides an anti-collision device for a building structure, which is arranged in an anti-seismic joint 1 between buildings on both sides, and includes: two fixing plates 2, a cylinder 3, two connecting columns 6, and a first spring 7. The two fixing plates 2 are fixedly connected to the building walls on both sides respectively, and the cylinder 3 is horizontally arranged between the two fixing plates 2. Spherical grooves 4 are provided in the cylinder 3 near the two ends, and a ball 5 is movably connected in the spherical groove 4. The ball 5 is provided with a sliding hole 51, and the center of the ball 5 is located on the center line of the sliding hole 51. The two connecting columns 6 are respectively slidably connected in the two sliding holes 51, and the ends of the two connecting columns 6 placed outside the cylinder 3 are respectively fixedly connected to the adjacent fixing plates 2, and the first spring 7 is placed in the cylinder 3, and the two ends of the first spring 7 are respectively fixedly connected to the ends of the two connecting columns 6.

[0028] In the above embodiment, the spherical groove 4 is close to the two ends of the cylinder 3, and the two ends of the cylinder 3 are open. The size of the spherical groove 4 is larger than the inner diameter of the cylinder 3. When the ball 5 is set in the spherical groove 4, it can be freely rotated. The sliding hole 51 provided in the ball 5 can realize the sliding of the connecting column 6 along the corresponding ball 5. When the buildings on both sides are close to or away from each other, the connecting column 6 will also tilt around the center of the ball 5 during the deviation process, and slide to the left or right along the sliding hole 51. The first spring 7 is mainly used to connect the ends of the two connecting columns 6 extending into the cylinder. The first spring 7 is made of a material with high toughness and rigidity. When the two connecting columns 6 are squeezed, they can realize elastic gathering and contraction. When the two connecting columns 6 move in a direction away from each other, the first spring The spring 7 can be stretched with high toughness to provide high-strength tensile force or supporting force for buffering. The cylinder 3 and the connecting column 6 are both made of high-hardness and high-strength metal materials after quenching, which can ensure that they have high stability. The sphere 5 is also made of solid steel. Compared with the existing device structure, the present device has stronger applicability and can be applied to various buildings. Even in severe disasters or weather conditions, the higher parts of the building shake with greater frequency and amplitude. In summary, the present device has strong practicality and can achieve effective anti-collision effects on various buildings. The present device is a combined connection structure of multiple independent components, has high toughness and can achieve a buffering effect. Compared with the existing method of relying on its own deformation to prevent building collisions, the present device greatly reduces the occurrence of safety hazards caused by excessive fatigue of a single component.

[0029] Further, refer to Figure 1 The two ends of the cylinder 3 are fixedly connected with the vertical plates 8. The vertical plates 8 are provided with avoidance holes 81 along the thickness direction near the cylinder 3. The diameter of the avoidance holes 81 is larger than the outer diameter of the connecting column 6. The two connecting columns 6 are located between the fixed plate 2 and the vertical plates 8 and are sleeved with second springs 9. The two ends of the second springs 9 are fixedly connected with the fixed plate 2 and the vertical plates 8 respectively.

[0030] In the above embodiments, the vertical plate 8 is provided to support the second spring 9, similar to the role of a flange flange, wherein the avoidance hole 81 is larger than the connecting column 6, and its purpose is to avoid interference with the offset and tilted connecting column 6, wherein the second spring 9 further enhances the overall buffering effect of the device. The second spring 9, like the first spring 7, can not only buffer and reset the horizontal force, but also provide a longitudinal buffering effect as the building shakes, tilts, or even bends, so that the overall buffering effect is better and the stability is stronger.

[0031] Further, refer to Figure 1A slide groove 21 is vertically provided on the side where the two fixed plates 2 are close to each other, and a slider 22 is slidably connected to the upper and lower parts of each slide groove 21. A connecting rod 23 is hinged on the side of each slider 22 close to the fixed plate 2, and the other end of the connecting rod 23 is hinged to the adjacent vertical plate 8. A third spring 24 is arranged between the two sliders 22 in the same slide groove 21, and the two ends of the third spring 24 are fixedly connected to the corresponding two sliders 22 respectively.

[0032] In the above embodiments, in order to enhance the stable connection between the fixed plate 2 and the vertical plate 8, the connecting rod 23 and the slider 22 are provided to achieve a tight connection between the two. When the two buildings are close to each other, the two sliders 22 will slide away from each other. The third spring 24 provided can tighten and buffer the two sliders 22, thereby enhancing the toughness of the overall structure.

[0033] Further, refer to Figure 1 The outer diameter of the connecting column 6 is half the size of the inner diameter of the opening of the cylinder 3 .

[0034] In the above embodiments, it is possible to provide limited adjustment for the inclination of the connecting column 6 .

[0035] The first connection implementation method is that the connection column 6 is fixedly connected to the fixing plate 2 through a flange and high-strength bolts.

[0036] In the above embodiments, the conventional connection method is used, but there is a problem that the installation is too tight and difficult to disassemble for later maintenance, so the second implementation method can also be selected.

[0037] Further, refer to Figure 1 , the fixing plate 2 is anchored to the building wall.

[0038] Further, refer to Figure 3 , Figure 4 and Figure 5The fixing plate 2 is connected to the building wall through a connecting assembly 10. The connecting assembly 10 in the second connection mode embodiment includes: a connecting plate 101 and two latches 103, wherein the side wall of the connecting plate 101 is fixedly connected to two sleeves 102, and the center line extension direction of the sleeve 102 is perpendicular to the center line of the cylinder 3. The two latches 103 are located between the two sleeves 102 and are respectively inserted into the sleeves 102. The axis of the latch 103 is parallel to the fixing plate 2. When the upper latch 103 moves upward and the lower latch 103 moves downward, it can be plugged with the sleeve 102. The fixing plate 2 is vertically provided with a sliding cavity 25 corresponding to the position of the two latches 103. The two latches 103 are connected to the sliding member 1 04 slides along the sliding cavity 25, and a double-headed screw 105 is vertically inserted in the sliding cavity 25. The double-headed screw 105 is rotatably connected to the inner wall of the fixed plate 2. The two sliding members 104 are respectively arranged on the two threaded sections of the double-headed screw 105. The sliding member 104 is threadedly connected to the double-headed screw 105. When the double-headed screw 105 is rotated, the two sliding members 104 will respectively drive the two latches 103 to slide in the directions of approaching or moving away from each other. When the two sliding members 104 are controlled to slide in the directions of moving away from each other, the two latches 103 can realize the connection between the latches 103 and the sleeve 102, so as to realize the connection between the fixed plate 2 and the building wall. Compared with the connection with bolts, this method is convenient for installation and disassembly.

[0039] In the above embodiments, the second embodiment will facilitate the anti-collision device of the building structure to be able to be vertically embedded in the seismic joint 1. Under the rotation action of the double-headed screw 105, the pin 103 is connected to the sleeve 102, so as to replace the previous bolt fixing connection, and realize quick installation and fixation, ensuring that the anti-collision device can be stably connected with an adjacent group of building structures. At the same time, it is different from the previous method of fixing steel plates with bolts to connect the building structure and the anti-collision device. Under the connection action of multiple groups of matching plug-in limiting structures, it can also avoid the problem of bolt loosening caused by multiple vibrations of the anti-collision device, and the whole is not easy to loosen and separate from an adjacent group of building structures.

[0040] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
