Description

Technical Field

[0001] The utility model relates to the field of combined steel beams, in particular to a combined steel beam with earthquake-resistant performance. Background Art

[0002] Steel beams are beams made of steel. Crane beams and working platform beams in factories, floor beams in multi-story buildings, purlins in roof structures, etc. can all be made of steel beams. When using steel beams, it is sometimes necessary to connect and combine two sets of steel beams for use. China's authorized utility model patent (Announcement No.: CN220318945U) discloses a combined steel beam with good bearing capacity. The first reinforcing plate, the second reinforcing plate, the arc-shaped clamping joint, the fixing plate, the clamping hole and the connecting groove are used in combination to greatly improve the bearing capacity of the steel beam, prevent the appearance of the steel beam from being deformed due to insufficient bearing capacity and affect normal use, and improve practicality.

[0003] However, the above device still has some shortcomings when in use: when the first steel beam and the second steel beam in the above device are butt-jointed, it is necessary to squeeze the arc-shaped clamping joint by hand or with the help of an adaptive tool to squeeze the first return spring, so that the arc-shaped clamping joint shrinks into the corresponding groove body, so that the first reinforcement plate can be inserted into the connecting groove. This process is not only complicated to operate, but also requires precise control of the force and angle, which makes the operation time-consuming and inconvenient to operate during docking, which increases the difficulty of construction and reduces work efficiency. Therefore, a combined steel beam with seismic resistance is proposed in view of the above situation. Utility Model Content

The protruding end of the second step rod is rotatably connected to an operating plate, and a second spring is sleeved on the second step rod.

[0029] The following is combined with Figure 1 —7 further details of this application,

[0030] The present application discloses a combined steel beam with earthquake resistance. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A combined steel beam with earthquake-resistant performance includes a first steel beam 1, a longitudinal slot 102 and a second steel beam 2. The first steel beam 1 is provided with a transverse plug plate 201 and a pair of longitudinal plug plates 202, and the second steel beam 2 is provided with a transverse plug plate 201 and a pair of longitudinal plug plates 202.

[0031] A second step hole 2020 is provided on the longitudinal plug plate 202, and a accommodating cavity 2021 is provided in the second step hole 2020. A third step hole 2022 connected to the accommodating cavity 2021 is provided on the top of the second steel beam 2, and a first step rod 203 is provided in the third step hole 2022. A first sphere 205 is fixedly connected to the bottom of the first step rod 203, and the first sphere 205 is located in the accommodating cavity 2021. The outer wall of the first step rod 203 is sleeved with a first spring 204.

[0032] A first step hole 103 passing through the first steel beam 1 is opened on the longitudinal slot 102, and a positioning assembly 3 is arranged in the first step hole 103. The positioning assembly 3 includes a second step rod 301 arranged in the second step rod 301, and a hemisphere 302 is arranged at the end of the second step rod 301. The protruding end of the second step rod 301 is rotatably connected to an operating plate 304, and a second spring 303 is sleeved on the second step rod 301.

[0033] The positioning assembly 3 includes a pair of limit blocks 305 arranged on the surface of the first steel beam 1 .

[0034] The transverse plug plate 201 is plugged into the transverse slot 101 , the longitudinal plug plate 202 is plugged into the longitudinal slot 102 , the second step rod 301 cooperates with the second step hole 2020 , and the protruding end of the first step rod 203 extends into the transverse plug plate 201 .

[0035] Reference Figure 5 A limiting ring is provided at the end of the first step rod 203 passing through the third step hole 2022 , and the radius of the limiting ring is greater than the radius of the third step hole 2022 .

[0036] Furthermore, the limiting ring ensures that the first step rod 203 will not slide downward out of the third step hole 2022 .

[0037] Reference Figure 3 , Figure 5 and Figure 6 A pair of through slots 1010 are provided in the transverse slot 101, and the pair of transverse slots 101 are respectively connected to the longitudinal slots 102. A pair of positioning holes 2010 are provided at the bottom of the transverse plug plate 201. The radius of the positioning holes 2010 is the same as the radius of the through slot 1010. The limiting ring on the first step rod 203 passes through the through slot 1010 and extends to the positioning hole 2010.

[0038] Furthermore, the through groove 1010 serves as a passage for the first step rod 203 to rise, so that the first step rod 203 can be moved into the positioning hole 2010 for longitudinal positioning.

[0039] Reference Figure 1 and Figure 2 A pair of hanging rings are provided on the surfaces of the first steel beam 1 and the second steel beam 2.

[0040] Furthermore, by arranging a pair of hanging rings on the surfaces of the first steel beam 1 and the second steel beam 2, the hanging rings can serve as connecting ropes, so that the first steel beam 1 and the second steel beam 2 can be lifted and connected by a lifting device.

[0041] Reference Figure 7 A handle is provided on the surface of the operating panel 304, and an arc chamfer is provided on the surface of the operating panel 304.

[0042] Furthermore, the handle is provided to facilitate operation by the staff.

[0043] Reference Figure 7 A pair of limit blocks 305 both have arc-shaped slots, and the maximum distance between the pair of arc-shaped slots is the same as the maximum distance between the two ends of the operating plate 304. The pair of limit blocks 305 are used to limit the operating plate 304, and the operating plate 304 can be snapped into the arc-shaped slots.

[0044] Working principle: After lifting the first steel beam 1 and the second steel beam 2, the horizontal plug plate 201 is inserted into the horizontal slot 101, and the longitudinal plug plate 202 is inserted into the longitudinal slot 102, and then the operating plate 304 is pulled to move the operating plate 304 out of the arc-shaped slot of a pair of limit blocks 305. After rotating the operating plate 304 90°, release the operating plate 304. Under the reset of the second spring 303, the second step rod 301 extends from the first step hole 103 into the second step hole 2020, thereby realizing the positioning of the longitudinal plug plate 202, that is, realizing the horizontal positioning of the first steel beam 1 and the second steel beam 2.

[0045] When the second step rod 301 extends into the second step hole 2020, the hemisphere 302 squeezes the first sphere 205, causing the first sphere 205 to move upward, thereby causing the first step rod 203 to move upward, thereby causing the first step rod 203 to pass through the third step hole 2022 and extend into the positioning hole 2010, thereby achieving synchronous limiting of the first steel beam 1 and the second steel beam 2 in the vertical direction, effectively preventing the relative displacement of the first steel beam 1 and the second steel beam 2 in the vertical direction, further improving the positioning effect, and enhancing the seismic performance of the structure, so that the combined steel beam can better maintain stability when natural disasters such as earthquakes occur.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
