A rubber gasket 24 is fixed on the surface of the limiting clamp 3. After the bolts 23 are locked, the rubber gasket 24 is compressed and elastically deformed.

[0036] Embodiment 2

[0037] See attached Figures 6 to 8As shown, on the basis of the first embodiment, in order to realize the pre-positioning of the limiting clamping plate 3 on the steel structure column 1, two parallel side walls of the through-opening 1 4 are provided with through-opening 2 5, and side grooves 6 are provided on both sides of the limiting clamping plate 3. The side grooves 6 are connected to the through-opening 2 5, and the slot size of the side grooves 6 is larger than the slot size of the through-opening 2 5. The top support plate 7 is movably inserted in the through-opening 2 5, and the long side length of the top support plate 7 is greater than the depth of the through-opening 2 5. The top support plate 7 extends toward the through-opening 1 One end of the top support plate 7 is provided with an inclined surface 8, and the other end of the top support plate 7 is fixed on the surface of the elastic band 9, and the elastic band 9 is fixed on the surface of the side groove 6. After the push plate 10 pushes the two top support plates 7, the top support plate 7 tensions the elastic band 9 to produce elastic deformation, and the elastic band 9 is clamped between the steel structure column 1 and the top support plate 7; the push plate 10 is a "T"-shaped plate structure, and the width of the plate body at one end of the push plate 10 is greater than the width of the slot of the through-mouth 4, and the plate body at one end of the push plate 10 Both ends of the 1000-1000-0100 1000-10 ... An embedding groove 14 is provided, and the baffle 15 is an inverted "concave" shaped block. One end of the baffle 15 extending out of the embedding groove 14 is provided with a second inclined surface 16, and the second inclined surface 16 faces the pushing end of the push plate 10. A rubber stay 17 is fixed in the groove body of the baffle 15, and the bottom end of the rubber stay 17 is fixed to the bottom surface of the embedding groove 14. The height of the baffle 15 is less than the depth of the embedding groove 14. The rubber stay 17 pushes the baffle 15 out of the embedding groove 14 for a distance in the initial state.

[0038] It is necessary to pre-install a set of limit clamps 3 below the position where the steel structure beam 2 is inserted into one side of the steel structure column 1, that is, the limit clamps 3 are installed on both sides of the steel structure column 1. After the limit clamps 3 are inserted into the groove of the steel structure column 1, when the bolts 23 are not installed, the push plate 10 is inserted into the through-opening 4. As the push plate 10 is pushed in the through-opening 4, the push plate 10 pushes the top support plate 7 along the inclined surface 8. After the top support plate 7 is stressed, it slides along the through-opening 5. The top support plate 7 tensions the elastic band 9 to produce elastic deformation, and the elastic band 9 is clamped at the side plate of the steel structure column 1. After the retaining bar 15 passes over the through-opening 4, the rubber support strip 17 squeezed and deformed by the retaining bar 15 rebounds. When the retaining bar 15 is supported by the rubber support bar 17 and blocked on one side of the through-opening 4, the push plate 10 is limited in the through-opening 4 and cannot be pulled out, that is, the two top support plates 7 are tightly against the side plates of the steel structure column 1 to prevent the limiting clamping plate 3 from loosening; after the limiting clamping plates 3 are installed on both sides of the steel structure column 1, the bolts 23 are passed through the through holes 22 on the surface of the steel structure column 1 and the limiting clamping plates 3 and then locked, so that the limiting clamping plates 3 are reinforced on the steel structure column 1, and after the steel structure beam 2 is inserted into the groove body of the steel structure column 1, the steel structure column 1 is overlapped on the limiting clamping plates 3; then another set of limiting clamping plates 3 are installed on the steel structure column 1, and the other set of limiting clamping plates 3 are above the steel structure beam 2.

[0039] See attached Fig.11 As shown, in order to cancel the pre-limit between the limit clamp 3 and the steel structure column 1, a socket 18 is opened on the top surface of the through-hole 4, and the pressure plate 19 is an "L"-shaped plate structure. The pressure plate 19 is movably inserted in the socket 18. The height of the pressure plate 19 is greater than the depth of the socket 18. A reserved opening 20 is opened on the surface of the pressure plate 19, and an elastic band 21 is inserted into the inside of the reserved opening 20. The two ends of the elastic band 21 are respectively fixed on two parallel side walls of the socket 18. In the initial state of the elastic band 21, the pressure plate 19 is suspended above the baffle 15.

[0040] When it is necessary to remove the side plate of the steel structure column 1 clamped by the top support plate 7, the pressure plate 19 is squeezed downward, and the pressure plate 19 stretches the elastic band 21 to deform. During the descending process of the pressure plate 19, the pressure plate 19 pushes the baffle 15 into the embedding groove 14. After the top plate of the pressure plate 19 overlaps the top surface of the limiting clamp 3, the top surface of the baffle 15 and the top surface of the push plate 10 are coplanar. The fingers are picked in the picking groove 13 to pull the push plate 10 out of the opening 4. When the push plate 10 no longer blocks the top support plate 7, the elastic band 19 rebounds and pulls the top support plate 7 to retract into the opening 25. At this time, the anti-slip limit between the limiting clamp 3 and the steel structure column 1 is cancelled.

[0041] Embodiment 3

[0042] See attached Figure 2 as well as Fig.14As shown, on the basis of Example 2, in order to improve the seismic effect of the two groups of limit clamps 3 when pre-limiting the steel structure beam 2, a mounting groove 25 is provided on the bottom surface of the limit clamp 3, and the top surface of the rubber pad 26 is fixed on the top surface of the mounting groove 25. The thickness of the rubber pad 26 is greater than the height of the mounting groove 25, and a "U"-shaped groove is provided on the bottom surface of the rubber pad 26. An elastic support frame 27 is fixed on the surface of the "U"-shaped groove. The elastic support frame 27 is in the shape of a "J" shape, and a rubber pad 2 28 is fixed to the bottom surface of the top plate of the elastic support frame 27.

[0043] After the limiting clamps 3 on the upper and lower sides of the steel structure beam 2 are installed, the rubber pad 1 26, the elastic support frame 27 and the rubber pad 2 28 are clamped between the steel structure beam 2 and the limiting clamps 3 to produce elastic deformation, which is used to reduce the vibration transmitted from the surface of the steel structure beam 2. The two groups of limiting clamps 3 limit the steel structure beam 2 to avoid the phenomenon of the steel structure beam 2 falling off when the steel structure beam 2 is not welded to the steel structure column 1. The reason why two groups of limiting clamps 3 are used to pre-limit the steel structure beam 2 is not only convenient for neatly assembling the steel structure column 1 and the steel structure beam 2 before welding, but also has low welding efficiency and high work technical requirements. During the construction process, multiple groups of steel structure beams 2 can be limited on the matching steel structure column 1, and welding staff can be arranged to weld the pre-limited steel structure column 1 and steel structure beam 2 to avoid the same staff from performing welding work after completing the pre-limiting, which is beneficial to improving the overall construction efficiency on site.

[0044] Embodiment 4

[0045] See attached Figure 3 as well as Fig.13 As shown, on the basis of the third embodiment, in order to realize the connection and limit of the two sets of limit clamping plates 3, connecting plates 29 are fixed on both sides of the limit clamping plates 3, and the connecting plates 29 are in an "L"-shaped plate structure. A rubber corner piece 30 is fixed at the inner corner of the connecting plate 29, and the rubber corner piece 30 is clamped between the connecting plate 29 and the steel structure column 1. A second notch 31 is opened at one end of the connecting plate 29, and the height of the second notch 31 is less than the thickness of the connecting plate 29. A screw column 32 is fixed to the bottom surface of the second notch 31, and the screw column 32 is in a semi-cylindrical structure, and one end of the connecting plate 29 is fixed with Rubber sheet 34; after the connecting plates 29 are installed on both sides of the steel structure column 1, the screw columns 32 on the two connecting plates 29 are assembled into a cylindrical structure with continuous threads, and a nut 33 is threaded on the rod body of the cylindrical structure; a clamping block 35 is fixed on the surface of the connecting plate 29, and after the ends of the two connecting plates 29 are brought together, the clamping blocks 35 on the surfaces of the two connecting plates 29 are inserted into the sleeve 36, and the sleeve 36 is opened on the surface of the connecting vertical plate 38, and a rubber baffle 37 is fixed on the surface of the clamping block 35, and the rubber baffle 37 is an "L"-shaped strip, which is used to limit the connecting vertical plate 38.

[0046] After the limit clamps 3 on both sides of the steel structure column 1 are pre-limited by the top support plate 7, the nuts 33 are sleeved and screwed on the two screwed columns 32. At this time, the connecting plates 29 on both sides of the two limit clamps 3 constitute a clamping structure, and the clamping structure is sleeved on the steel structure column 1 to strengthen the anti-slip effect of the limit clamps 3 after being pre-limited on the steel structure column 1; when the limit clamps 3 on the upper and lower sides of the steel structure beam 2 are installed, the sleeves 36 at both ends of the connecting vertical plate 38 are respectively sleeved on the blocks 35 on one side of the two groups of limit clamps 3 to control the spacing between the two groups of connecting plates 29, thereby preventing a group of limit clamps 3 from sliding.

[0047] Embodiment 5

[0048] Based on the fourth embodiment, a method for using a high-efficiency earthquake-resistant mechanism for a steel structure factory building is proposed, comprising the following steps:

[0049] Step 1: pre-install a set of limit clamps 3 below the position where the steel structure beam 2 is inserted into one side of the steel structure column 1, that is, the limit clamps 3 are installed on both sides of the steel structure column 1, and after the limit clamps 3 are inserted into the groove of the steel structure column 1, when the bolts 23 are not installed, the push plate 10 is inserted into the through-opening 1 4, and as the push plate 10 is pushed in the through-opening 1 4, the push plate 10 squeezes the top support plate 7 along the inclined surface 1 8, and the top support plate 7 slides along the through-opening 2 5 after being stressed, and the top support plate 7 tensions the elastic band 1 9 to produce elastic deformation, and the elastic band 1 9 is clamped at the side plate of the steel structure column 1, and after the retaining bar 15 passes over the through-opening 1 4, the rubber support strip 17 squeezed and deformed by the retaining bar 15 rebounds, At this time, the stop bar 15 is supported by the rubber support bar 17 and blocked on one side of the through-hole 14, that is, the push plate 10 is limited in the through-hole 14 and cannot be pulled out, that is, the two top support plates 7 are tightly against the side plates of the steel structure column 1 to prevent the limiting clamping plate 3 from loosening; after the limiting clamping plates 3 are installed on both sides of the steel structure column 1, the bolts 23 are penetrated through the through holes 22 on the surface of the steel structure column 1 and the limiting clamping plates 3 and then locked, so that the limiting clamping plates 3 are reinforced on the steel structure column 1, and after the steel structure beam 2 is inserted into the groove body of the steel structure column 1, the steel structure column 1 is overlapped on the limiting clamping plates 3; then another set of limiting clamping plates 3 is installed on the steel structure column 1, and the other set of limiting clamping plates 3 is above the steel structure beam 2;

[0050] Step 2: When it is necessary to remove the side plate of the steel structure column 1 that is clamped by the top support plate 7, the pressure plate 19 is squeezed downward, and the pressure plate 19 stretches the elastic band 21 to deform. During the descent of the pressure plate 19, the pressure plate 19 pushes the blocking bar 15 into the embedding groove 14. After the top plate of the pressure plate 19 overlaps the top surface of the limiting clamping plate 3, the top surface of the blocking bar 15 and the top surface of the push plate 10 are coplanar. The finger is picked in the picking groove 13 to pull the push plate 10 out of the through-opening 14. When the push plate 10 no longer blocks the top support plate 7, the elastic band 19 rebounds and pulls the top support plate 7 to retract into the through-opening 2 5. At this time, the anti-drop limit between the limiting clamping plate 3 and the steel structure column 1 is cancelled;

[0051] Step 3: After the limiting clamps 3 on the upper and lower sides of the steel structure beam 2 are installed, the rubber pad 1 26, the elastic support frame 27 and the rubber pad 2 28 are clamped between the steel structure beam 2 and the limiting clamps 3 to produce elastic deformation, which is used to reduce the vibration transmitted from the surface of the steel structure beam 2. The two sets of limiting clamps 3 limit the steel structure beam 2 to avoid the phenomenon of the steel structure beam 2 falling off when the steel structure beam 2 is not welded to the steel structure column 1. The reason why two sets of limiting clamps 3 are used to pre-limit the steel structure beam 2 is not only convenient for neatly assembling the steel structure column 1 and the steel structure beam 2 before welding, but also the welding work efficiency is low and the work technical requirements are high. During the construction process, multiple sets of steel structure beams 2 can be limited on the matching steel structure column 1, and welding staff are arranged to weld the pre-limited steel structure column 1 and steel structure beam 2 to avoid the same staff from performing welding work after completing the pre-limiting, which is conducive to improving the overall construction efficiency on site;

[0052] Step 4: After the limit clamps 3 on both sides of the steel structure column 1 are pre-limited by the top support plate 7, the nuts 33 are sleeved and screwed on the two screwed columns 32. At this time, the connecting plates 29 on both sides of the two limit clamps 3 constitute a clamping structure, and the clamping structure is sleeved on the steel structure column 1 to strengthen the anti-slip effect of the limit clamps 3 after being pre-limited on the steel structure column 1; when the limit clamps 3 on the upper and lower sides of the steel structure beam 2 are installed, the sleeves 36 at both ends of the connecting vertical plate 38 are respectively sleeved on the blocks 35 on one side of the two groups of limit clamps 3 to control the spacing between the two groups of connecting plates 29, thereby preventing a group of limit clamps 3 from sliding.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
