Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to an earthquake-resistant laminated steel structure. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields.

[0003] However, in the prior art, in order to ensure the stability of the steel structure, a rigid connection method is adopted between the steel plates and the connecting parts. Since the steel structure is made of hard materials, when it is vibrated by external impact, the transmission efficiency of mechanical vibration between steel materials is good, resulting in the vibration of the entire steel structure, which can easily cause the screws between the steel structure connecting parts to fall off. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the transmission efficiency of mechanical vibration between steel materials is good, resulting in vibration of the entire steel structure, which easily leads to the falling off of screws between steel structure connectors, and to propose a seismic-resistant laminated steel structure.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an earthquake-resistant laminated steel structure, which is composed of a number of laminated plates and conical buffer plates staggered together, wherein two laminated plates are stacked vertically, and two conical buffer plates are stacked horizontally, and the two groups of laminated plates and two conical buffer plates constitute an earthquake-resistant unit, and the laminated steel structure is an earthquake-resistant unit component arranged in an array. Due to the hexagonal structure of the laminated plates, the upper half of the side cross-section of the laminated plates is a rectangle, and the lower half is an isosceles trapezoid. The gap formed by the two groups of trapezoids is conical, wherein the two laminated plates are relatively arranged on both sides to form a conical cavity, and the shape of the conical buffer plate is a conical table corresponding to the conical cavity, wherein the inclined surface where the conical buffer plate fits the laminated plates has a small slope observed in the horizontal direction, and the conical buffer plate is slidably connected to the side wall of the conical cavity, and the surfaces of the laminated plates are provided with positioning holes, and the two positioning holes are slidably connected between the two positioning holes. A connecting tube is connected, and the laminate plate is a stepped circular through groove with a large upper opening and a small lower opening. The lower opening is used to insert the upper connecting tube so as to connect the two laminate plates to each other, and the upper opening is used to clamp the two ends of the connecting tube with the laminate plate through a ring structure to prevent the two laminate plate structures from spreading. A heavy object is placed on one of the seismic units of the laminated steel structure. After the heavy object hits and generates vibration, the laminate plates on the corresponding plates move toward each other due to the vibration, causing the conical cavities on both sides to narrow and then squeeze the conical buffer plates. The conical buffer plates at the vibrated location will slide toward the partition, and part of the vibration energy will be lost through the friction contact of the inclined surface. The vibration energy is absorbed by the movement of the laminate plates and the conical buffer plates to achieve the seismic effect. In addition, since the laminate plates on other seismic units and the laminate plates on the seismic module are independently distinguished from each other, the vibration energy below is absorbed by the ground and is less transmitted to other laminate plates, thereby achieving the seismic effect of the overall laminated steel structure.

[0006] Preferably, a buffer groove is formed on the side wall of the conical buffer plate, and a connecting column is slidably connected between two of the buffer grooves. The conical buffer plates of each seismic-resistant unit are interconnected through the connecting column so as to form a whole.

[0007] Preferably, the outer wall of the connecting column and the inner wall of the buffer groove are both provided with annular stripes, and the friction force generated by the annular stripes between the connecting column and the buffer groove is used to further absorb vibration energy, thereby improving the seismic resistance of the laminated steel structure.

[0008] Preferably, a partition is fixedly connected at the center position of the side wall of the connecting column, and the partition is filled in the gap between the two laminated plates. The gap between the horizontal laminated plates is filled by the partition to ensure that when the horizontal laminated plates slide independently of each other, the gap on the surface of the laminated steel structure is reduced as much as possible.

[0009] Preferably, the inner side wall of the connecting tube is provided with a threaded nail, and one end of the threaded nail is threadedly connected with a nut.

[0010] Preferably, the cavity of the positioning hole is in the shape of a truncated cone, the connecting tube is located at the small opening of the truncated cone, and the nut is located at the large opening of the truncated cone.

[0011] Preferably, disc springs are provided at both ends of the connecting column, and the connecting column is elastically connected to the side walls of the buffer groove through the disc springs. By stacking multiple layers of disc springs at the tail end of the connecting column, the connecting column has a reverse force on the conical buffer plates at both ends.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, two laminated plates are stacked vertically and two conical buffer plates are stacked horizontally, and the two groups of laminated plates and two conical buffer plates form a seismic unit, so that the laminated materials on the two seismic units are independent of each other. When a collision occurs at one place and vibration is generated, the independent laminated materials transfer the vibration energy to the ground for absorption, and less is transferred to other laminated plates, thereby achieving the seismic effect of the overall laminated steel structure and avoiding the problem of screws falling off at other positions on the steel structure.

[0014] 2. In the utility model, after vibration is generated by the impact of a heavy object, the laminated plates on the corresponding plates move toward each other due to the vibration, causing the conical cavities on both sides to narrow and squeeze the conical buffer plates. The conical buffer plates at the vibrated locations will slide toward the partitions, and part of the vibration energy will be lost through the frictional contact of the inclined surfaces. The vibration energy is absorbed by the movement of the laminated plates and the conical buffer plates, thereby achieving an anti-seismic effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1

[0023] like Figure 1-4 As shown, the utility model provides an earthquake-resistant laminated steel structure, which is composed of a number of laminated plates 1 and conical buffer plates 2 that are staggered, wherein two laminated plates 1 are relatively arranged on both sides to form a conical cavity, the conical buffer plate 2 is slidably connected to the side wall of the conical cavity, and positioning holes 3 are opened on the surface of the laminated plates 1, and a connecting tube 6 is slidably connected between the two positioning holes 3.

[0024] The specific configuration and function of this embodiment are described in detail below. Two laminated plates 1 are stacked vertically, and two conical buffer plates 2 are stacked horizontally. The two sets of laminated plates 1 and two conical buffer plates 2 constitute a seismic unit. The laminated steel structure is a seismic unit component arranged in an array. Due to the hexagonal structure of the laminated plates 1, the upper half of the side cross-section of the laminated plates 1 is a rectangle, and the lower half is an isosceles trapezoid. The gap formed by the two sets of trapezoids is conical, and the shape of the conical buffer plate 2 is a conical platform corresponding to the conical cavity, wherein the slope of the conical buffer plate 2 and the laminated plate 1 is small in the horizontal direction.

[0025] The laminate plate 1 is a stepped circular through groove with a large upper opening and a small lower opening. The lower opening is used to insert the upper connecting tube 6 so as to connect the two laminate plates 1 to each other, and the upper opening is used to clamp the two ends of the connecting tube 6 with the laminate plate 1 through a ring structure to prevent the two laminate plates 1 from spreading out. A heavy object is placed on one of the seismic units of the laminated steel structure. After the heavy object hits and generates vibration, the laminate plates 1 on the corresponding plate move toward each other due to the vibration, causing the conical cavities on both sides to narrow and squeeze the conical buffer plates 2. The conical buffer plates 2 at the vibrated location will slide toward the partition 4, and part of the vibration energy will be lost through the friction contact of the inclined surface. The vibration energy is absorbed by the movement of the laminate plates 1 and the conical buffer plates 2 to achieve a seismic effect. In addition, since the laminate plates 1 on other seismic units and the laminate plates 1 on the seismic module are independently distinguished from each other, the vibration energy below is absorbed by the ground and is less transmitted to other laminate plates 1, thereby achieving the seismic effect of the overall laminated steel structure.

[0026] Embodiment 2

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, the side wall of the conical buffer plate 2 is provided with a buffer groove 9, a connecting column 5 is slidably connected between the two buffer grooves 9, the outer wall of the connecting column 5 and the inner wall of the buffer groove 9 are both provided with annular stripes, a partition 4 is fixedly connected at the center of the side wall of the connecting column 5, and the partition 4 is filled in the gap between the two laminated plates 1, a threaded nail 7 is provided on the inner wall of the connecting cylinder 6, and a nut 8 is threadedly connected to one end of the threaded nail 7, the cavity of the positioning hole 3 is truncated cone-shaped, the connecting cylinder 6 is located at the small mouth of the truncated cone, and the nut 8 is located at the large mouth of the truncated cone. Disc springs are provided at both ends of the connecting column 5, and the connecting column 5 is elastically connected to the side wall of the buffer groove 9 through the disc springs.

[0028] The effect achieved by the entire embodiment is that the conical buffer plates 2 of each anti-seismic unit are connected to each other through the connecting column 5, so that they form a whole. The friction force generated by the annular stripes between the connecting column 5 and the buffer groove 9 further absorbs the vibration energy, thereby improving the anti-seismic effect of the laminated steel structure. The gaps between the horizontal laminated plates 1 are filled by the partition plate 4 to ensure that when the horizontal laminated plates 1 slide independently from each other, the gaps on the surface of the laminated steel structure are reduced as much as possible.

[0029] A hexagonal nut is provided at one end of the threaded nail 7, and the other end of the threaded nail 7 is connected by a nut 8, so that the two ends of the connecting tube 6 are clamped with the upper and lower layers of the laminated plates 1 to prevent the laminated plates 1 from falling off from each other. By stacking multiple layers of disc springs at the tail end of the connecting column 5, the connecting column 5 has a reverse pressure on the conical buffer plates 2 at both ends. In a natural state, the conical buffer plate 2 is inserted into the laminated plate 1, so that a seismic space is reserved between the two laminated plates 1.

[0030] The use method and working principle of the device: When vibrating, the laminated plates 1 move towards each other due to the vibration, causing the conical cavities on both sides to narrow and squeeze the conical buffer plates 2. The conical buffer plates 2 at the vibrated position will slide toward the partition plate 4, and part of the vibration energy will be lost through the friction contact of the inclined surface;

[0031] At the same time, since the laminated plates 1 on other earthquake-resistant units and the laminated plates 1 on the earthquake-receiving modules are independently distinguished from each other, the vibration energy below is absorbed by the ground and is less transmitted to other laminated plates 1, thereby achieving the earthquake-resistant effect of the overall laminated steel structure;

[0032] In addition, the friction force generated by the annular stripes between the connecting column 5 and the buffer groove 9 further absorbs the vibration energy, thereby improving the seismic resistance of the laminated steel structure.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
