Unless otherwise defined, the technical terms or scientific terms used herein should be the usual meanings understood by people with general skills in the field to which the present disclosure belongs. "Up", "down", "left", "right", "front", "back" and the like used in the patent application specification and claims of the present disclosure are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship also changes accordingly. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The parts not described in detail in the present invention are all known technologies of technicians in the field of this technology.

[0023] The present invention provides an earthquake-resistant metal building frame, such as Figure 1 As shown, the metal frame structure includes a plurality of fixed piles, and a cross bar 5 connected between the fixed piles, a vertical bar 7 connected between the cross bars 5, and a reinforcing bar 6 connected between the vertical bars 7; wherein the fixed piles include at least two columns 2 and a fixing rod 3 connected between the two columns 2; illustratively, in the present invention, a fixed pile is composed of two columns 2 and a fixing rod 3, and the two columns 2 are connected by the fixing rod 3; and the cross bar 5 is connected between two opposite fixed piles by a connecting component 4.

[0024] For example, Figure 3 and Figure 4As shown, a slide groove 22 is provided on the side of the column 2, and a plurality of limit grooves 21 are provided on both sides of the slide groove 22; the limit grooves 21 are arranged in groups; the connecting component 4 includes a support rod 42, an insertion rod 43, a bracket 45 and a spring 46; a support rod 42 is provided at the bottom end of the limit groove 21, and a spring 46 is provided at the top end of the support rod 42; a bracket 45 is provided at the top end of the spring 46; a locking rod 51 is provided on the side of the cross bar 5, and the locking rod 51 is inserted into the slide groove 22, and the locking rod 51 is cooperatively connected to the bracket 45; the locking rod 51 is cooperatively connected to the insertion rod 43 with the limit groove 21; a plurality of vertical rods 7 are detachably connected between the opposite cross bars 5, and a plurality of vertical rods 7 are detachably connected to the reinforcing rods 6.

[0025] When connecting the column 2 and the cross bar 5, the locking rod 51 on the side of the cross bar 5 is inserted into the slide groove 22, and the locking rod 51 is placed on the top of the bracket 45, so that the cross bar 5 compresses the spring 46 under the action of gravity. At the same time, the insertion rod 43 is inserted from the limiting groove 21, so that the insertion rod 43 passes through the limiting groove 21 and the locking rod 51, thereby completing the fixation of the cross bar 5 and the column 2.

[0026] When vibration occurs, when the horizontal bar 5 or the column 2 experiences vibration caused by the horizontal wave, the locking rod 51 moves left and right in the slide slot 22 by a certain distance to buffer the vibration caused by the horizontal wave; when vibration caused by the longitudinal wave occurs, the vertical movement of the horizontal bar 5 can drive the insertion rod 43 to move up and down in the limit slot 21, and cooperate with the spring 46 at the bottom to buffer. The vibration caused by the horizontal and longitudinal waves can be effectively buffered to achieve a good anti-seismic effect, and the overall disassembly and assembly are convenient, and the connection strength is high.

[0027] In order to further strengthen the stability of the connection between the crossbar 5 and the column 2, and prevent the two from being separated from the crossbar 5 and the column 2 under strong vibration; the connection component 1 4 also includes a linkage rod 41 and a mounting plate 44; the crossbar 5 is detachably connected to the mounting plate 44, and the mounting plate 44 is rotatably connected to the supporting rod 42 by the linkage rod 41. When the column 2 and the crossbar 5 are installed, the mounting plate 44 is installed on both sides of the crossbar 5, so that the crossbar 5 and the supporting rod 42 are strengthened by the linkage rod 41. When the crossbar 5 is separated from the column 2, the linkage rod 41 can firmly tighten the crossbar 5 to prevent the crossbar 5 from falling off the column 2 and collapsing during vibration. Therefore, the movable connection of the linkage rod 41 plays the final reinforcement effect and can further improve the safety performance.

[0028] In order to connect the vertical rod 7 between the two opposite horizontal rods 5 to strengthen the fixation, the present invention designs a second connecting component 8, the surface of the horizontal rod 5 is provided with a second slide groove 52, and the second slide groove 52 is matched with a plurality of groups of second connecting components 8 arranged symmetrically in pairs; the second connecting component 8 detachably connects the vertical rod 7 to the horizontal rod 5. For example, as Figure 2 As shown, the second connecting assembly 8 includes a slider 81, a locking bolt 82, a second clamping slot 83 and an elastic gasket 84; the slider 81 is connected to the second sliding slot 52, and the slider 81 is fixed to the cross bar 5 by the locking bolt 82; the side of the slider 81 is provided with a second clamping slot 83, and the second clamping slot 83 is provided with an elastic gasket 84; the two sides of the vertical rod 7 are fixed with an overhanging block 71, and the overhanging block 71 is connected to the second clamping slot 83. The cross section of the slider 81 adopts an "L"-shaped structure, and the slider 81 extends into the second sliding slot 52.

[0029] When connecting the cross bar 5 and the vertical bar 7, first determine the position of the vertical bar 7, loosen the locking bolt 82, and then move the connecting component 2 8 to a suitable position, place the vertical bar 7 between the two connecting components 2 8, and insert the two protruding blocks 71 of the vertical bar 7 into the two card slots 2 83 of the two connecting components 2 8 respectively; and ensure that the protruding blocks 71 of the vertical bar 7 will not fall out of the card slots 2 83 when the vertical bar 7 moves left or right; then use the locking bolt 82 to lock, when vibration occurs, the vertical bar 7 moves left and right to press the elastic gasket 1 84 to buffer the vibration, and the vertical bar 7 will not fall out. The present invention ensures that the cross bar 5 and the vertical bar 7 are stably connected and can withstand vibration within a predetermined range, and ensures that the vertical bar 7 is prevented from separating from the cross bar 5 due to the exercise of the connection during the fixed connection, and collapse after the vibration.

[0030] In order to realize the detachable connection between the vertical rod 7 and the reinforcing rod 6, a card slot 73 is provided on the surface of the vertical rod 7, and the card slot 73 extends to both sides; a limiting groove 72 is provided on the top of the vertical rod 7, and the limiting groove 72 is connected to the card slot 73; the card slot 73 and the limiting groove 72 are cooperated and connected with a connecting component 3 9, and the connecting component 3 9 connects the reinforcing rod 6 to the vertical rod 7 in a detachable manner.

[0031] like Figure 5 As shown, the connection assembly 3 9 is provided with two and symmetrically distributed on the side of the card slot 1 73; the connection assembly 3 9 includes a slide plate 91, a linkage plate 92, a mounting hole 93 and an elastic gasket 2 94; the linkage plate 92 is inserted into and connected to the extension of the card slot 1 73, and the side of the linkage plate 92 is fixed with a slide plate 91; the slide plate 91 is connected to the limiting slot 2 72; the bottom end of the linkage plate 92 is provided with an elastic gasket 2 94, and the surface of the linkage plate 92 is provided with a mounting hole 93; the mounting hole 93 is connected with a bolt. The linkage plate 92 adopts an "L"-shaped structure, and the linkage plate 92 is inserted into and slidably connected to the extension of the card slot 1 73; the height of the slide plate 91 is not less than the height of the vertical rod 7.

[0032] When connecting the vertical rod 7 and the reinforcing rod 6, the reinforcing rod 6 is placed between the two connecting components three 9, and then the linkage plate 92 is connected to the reinforcing rod 6 by bolts. After the connection, both sides of the reinforcing rod 6 are connected to the vertical rod 7 through the connecting components three 9. When vibration occurs, the reinforcing rod 6 moves, which can drive the linkage plate 92 to move at the extension of the slot one 73, thereby alleviating the vibration. At the same time, when the vibration caused by the longitudinal wave occurs, the elastic gasket two 94 can be pressed for buffering.

[0033] The bottom end of the column 2 of the same fixed pile is fixed with an insertion component 1, and the insertion component 1 includes a positioning groove 11, a connecting rod 12 and an insertion head 13; the connecting rod 12 is fixed to the bottom end of each column 2, and the bottom end of the connecting rod 12 is provided with an insertion head 13; a plurality of positioning grooves 11 are provided on the side of the connecting rod 12. When installing fixed piles, cement is generally used to cast the foundation, and then the insertion component 1 is inserted into the foundation. After insertion, the cement solidifies, and the insertion component 1 is fixed inside without shaking. The positioning groove 11 increases the connection area between the cement and the insertion component 1, which is used to strengthen the connection stability between the insertion component 1 and the foundation.

[0034] In summary, the various connection points between the earthquake-resistant building metal frames of the present invention are movable connections, which can eliminate the fluctuations caused by vibrations through movement, avoid the breakage of hard connections, and increase safety performance.
