Description

Plate energy dissipating shock absorber and assembling method thereof

The invention relates to a plate-shaped energy dissipation damper and an assembly method thereof; in particular, a device for preventing vibration or vibration of a general building structure, which is fixed by a fixed end of a complex array energy dissipation plate and a complex array After the boards are superimposed and superimposed, the connecting rods are connected in series to form an energy dissipating body; or the fixed end of the complex array energy dissipating board is superimposed with the complex array partitioning board and the multi-array fixed board, and then the connecting rods are serially locked and locked. Forming the energy dissipating body; inserting the fixing plate of the energy dissipating body into the through hole of the fixing seat, and fixing the fixing plate to the fixing seat from the other end of the insertion end of the through hole, the upper fixing seat and the lower fixing seat are opposite to the horizontal longitudinal direction When moving, it can produce energy dissipation.

As shown in the first figure, the bulletproof number 361485 "enhanced anti-shock energy dissipating device" (01) is used to fix the energy-dissipating steel plate by welding. However, since the welded portion is liable to cause embrittlement of the steel plate material, the force is repeated. Under the action, the welded portion is prone to breakage, and the energy dissipation effect of the energy-dissipating steel plate is reduced.

Figure 2 shows the certificate number M242534 "Moisture-free universal structure anti-vibration device" (02). The energy-dissipating steel plate and the L-shaped fixing seat are connected by bolts. The metal damper welded portion shown in Fig. 1 is prone to breakage. The problem. When multiple sets of energy-dissipating steel sheets are assembled in series, the length of the metal damper will become longer, but all the bearing forces are still concentrated on the single-sided L-shaped fixing seat, and cannot be evenly distributed on the connected structural members.

FIG. 3 is a diagram showing an energy dissipator (03) of the application No. 200920904 "plate-shaped energy absorbing damper", which is characterized in that a multi-array base is connected in series to sandwich a pedestal. The energy component is combined into an energy dissipating body, and each set of the base on the energy dissipating body is fixed to the joint by bolts or welding, but if the bolt is locked, the size of the base must be increased to provide The bolt locking space and the necessary edge thickness make the size of the energy dissipating shock absorber also need to be enlarged; if it is locked by welding, the bottom of the base must be raised to provide the position of the bead. Since other components hinder the welding, it must be faked. The action is to first remove the components other than the base, and after all the bases and the joints are welded, and then re-assembled, not only the assembly process is cumbersome, but the deformation after welding changes the width between the base and the base, which may cause a plate shape. It is difficult for the energy dissipating component to be inserted into the assembly.

Figure 4 shows the certificate number M360910 "The energy dissipation damper with anchor support" (03), with the sliding link connecting through the fixed spacers, the movable partition plate and the variable section steel plate which are superimposed on each other and locked by the nut The fixed partition plate and the lower positioning steel plate are weldedly connected, but the fixed partition plate and the lower positioning steel plate are joined to form a groove for inserting the movable partition plate and the variable section steel plate, due to the width of the groove and the partition plate and the breaking The thickness of the surface steel plate needs to be precisely matched, so it is necessary to first perform the procedure of false assembly. After the fixed spacer plate and the lower positioning steel plate are spot welded and fixed, the movable partition plate and the variable section steel plate are removed, and there is space for the fixed partition plate and The joint of the lower positioning steel plate is used for fillet welding. After welding, the movable partition plate and the variable section steel plate are inserted into the groove formed by welding the fixed partition plate and the lower positioning steel plate, but the welding plate may cause deformation of the steel plate, so it is easy to have The looseness will be swayed, or it will be too tight to be inserted, and the assembly process will be difficult. The assembly method is the same as that of the plate-shaped energy dissipation damper shown in Figure 3. the same.

The assembly method of the plate-shaped energy dissipation damper of the invention is that the fixed end of the complex array energy dissipation plate is superimposed with the complex array fixed plate, and the energy dissipating body is formed by connecting the rods in series; or the complex array is eliminated The fixed end of the energy board is superimposed with the complex array spacer board and the multi-array fixed board, and the energy-dissipating body is formed by serially connecting the connecting rods.

The fixing seat is provided with a through hole corresponding to the size and the number of the fixing plate, and the fixing plate of the energy dissipating body is embedded in the through hole of the fixing seat, and the fixing plate is welded and fixed to the fixing seat from the other end of the insertion end of the through hole.

Because the fixing plate and the through hole of the fixing seat are processed by welding, the dimensional accuracy of the through hole of the fixing plate and the fixing seat can be loosely matched, and the plate-shaped energy dissipation is completed after the fixing plate and the fixing seat are welded and connected in the through hole. The assembly of the shock absorber does not require pre-emptive assembly action, disassembly, re-soldering, re-assembly, etc., which is time-consuming and labor-intensive; there will be no gaps in the panel, or the space is too tight. It is difficult to insert into the group, and it has the advantage of quickly completing the assembly and shaking the structure with a solid structure.

Since the welding position is on the fixing plate, not on the energy dissipating plate, the energy dissipating plate does not cause embrittlement and cracking of the steel material.

In addition, the connecting plates can be connected between the fixing plates to increase the strength and stiffness of the fixed ends, and the stiffening plates can be welded between the fixed plates on the outermost sides and the fixed seat, which can increase the strength and strength of the fixed plate and the fixed seat.

After this step is completed, the plate-shaped energy absorbing damper (10) is assembled.

The final step is as shown in Fig. 8. In order to strengthen the strength and stiffness of the fixed end, the fixing plate on the outermost side is welded and arranged with a stiffening plate (35) to connect the fixing plate (33) and the fixing seat (20), and The reinforcing of the fillet welding of the plate can be applied to the surrounding position of the convenient construction to complete the final assembly of the plate-shaped energy absorbing shock absorber.

Figure 9 to Figure 12 show the components, assembly methods, and assembly steps of the preferred version of the energy dissipating body (30) to increase the spacing of the spacers (32).

The difference is that the energy dissipating body is hinged at one end and the other end is connected. In combination, the hinge end is a manner in which the connecting rod is inserted into the connecting hole position as a bearing hole position, and the roller connecting end is a manner in which the connecting rod is inserted into the connecting hole to be a long hole, so that the upper fixing seat and the lower fixing seat can generate a relative vertical direction.
