Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1 to 4, the embodiment of the cold-formed steel for the road and bridge steel guardrail with better anti-collision and buffering effects of the present invention includes a beam 1, the beam has a concave structure and the concave portion 2 of the beam is arranged along the horizontal direction, so that the accumulation of rainwater and other liquids in the groove can be avoided, and when the cold-formed steel is locked, the screw can be hidden, and at the turning position, a warning or guiding reflective component can be arranged in the concave portion, and the concave portion has guiding and positioning functions, so that the assembly is convenient and reliable; the back side that the crossbeam concave part corresponds comprises last hypotenuse 3 and flagging 4, goes up the hypotenuse and is connected with the last side 5 of crossbeam, and the lower hypotenuse is connected with the lower side 6 of crossbeam, goes up the hypotenuse and is located the flagging outside and partial coincidence setting, and the crossbeam passes through buffering adapter sleeve 7 to be connected with stand 8, and the stand is square tubular construction, and the stand bottom is provided with connection bottom plate 9, two corresponding surfaces of buffering adapter sleeve respectively with the back side butt of stand and crossbeam. The stand is fixed through the pre-buried foundation pile lock solid of setting on connecting bottom plate and ground or the bridge floor, install the crossbeam afterwards, when the installation, add the buffering adapter sleeve between crossbeam and the stand, directly penetrate from the concave part of crossbeam through the screw, then pass the hem, go up the hypotenuse, adopt the nut lock solid behind buffering adapter sleeve and the stand, after the lock solid, go up hypotenuse atress deformation, and two surfaces respectively with hem and the laminating of buffering adapter sleeve surface, the produced reaction force of deformation can guarantee the stability of overall structure behind the lock solid, can not cause the nut pine to take off because of vibrations scheduling problem, also convenient assembly. When the striking takes place, the concave part structure of crossbeam at first contacts with the striker, the deformation can take place for the very first time for the concave part structure, the deformability is better than the plane and intensity is high, consequently, play first layer buffering effect, afterwards, the power can be transmitted on the buffering adapter sleeve, the buffering adapter sleeve atress flattens, play second floor buffering effect through self deformation promptly, the buffering adapter sleeve is long circle structure or hexagon structure, can effectively deform, final impact passes through the stand and transmits to ground, the striker is effectively blockked, and received good buffering when blockking, the striking injury has been reduced.

Because the impact is finally transmitted to ground by the stand, so the intensity of stand is very crucial, through be provided with slot part 10 on two corresponding surfaces at the stand, compare with ordinary cast, under the same thickness condition, can improve structural strength greatly, improve and block the effect. The buffer connecting sleeve is arranged opposite to the groove part on the upright column, the surface of the buffer connecting sleeve is provided with the profile modeling convex part 11, the profile modeling convex part is arranged in the corresponding groove part, when the buffer connecting sleeve is assembled, the buffer connecting sleeve is effectively limited, the buffer connecting sleeve cannot rotate along the circumferential direction of the screw, the consistency is good after the assembly, the positioning effect can be preliminarily achieved on the hole for locking, and the buffer connecting sleeve can be matched only by adjusting the upper part and the lower part, so that the assembly is convenient.

In one embodiment, as shown in fig. 5 to 7, a plurality of plastic grid support plates 12 are provided within the cushion connection sleeve. The plastic grid supporting plate can strengthen the internal strength of the buffer connecting sleeve, and can be effectively adjusted according to the strength requirement of use, thereby improving the universality of the buffer connecting sleeve and avoiding the buffer connecting sleeve from being incapable of being used due to thinner wall thickness. Still be connected with shrouding 13 at a plurality of plastics grid backup pad tops, the shrouding is fixed with buffering adapter sleeve top joint, through the design of shrouding, can effectively block entering buffering adapter sleeve such as rainwater in, avoids causing the corruption injury to inside screw structure, also can increase pleasing to the eye degree.

Still be provided with L type backup pad 14 on the surface that the buffering adapter sleeve is located crossbeam one side, under this structure, can lock the buffering adapter sleeve in advance or weld on the stand, it can to guarantee that the hole aligns, the crossbeam is when the assembly, the buffering adapter sleeve surface of laminating with last hypotenuse moves down, make the top butt of going up the hypotenuse bottom and L type backup pad of going up the hypotenuse crossbeam, play the effect of preliminary support, because the gradient is not big, therefore the hole site can not the off normal too much, both can wear to establish the screw, the support of crossbeam is established weight and can be shifted for the buffering adapter sleeve through last hypotenuse this moment, the operation is laborsaving relatively, lock through the nut afterwards, in-process, go up the hypotenuse deformation, finally laminate in the lower vertical limit, accomplish the lock. The L-shaped supporting plate can also be used for supporting the lower side edge of the cross beam to achieve the limiting effect, the weight of the cross beam is effectively transferred, and the force acting on the screw is reduced. The design of the concave part enables the cross beam to be manufactured by a thinner steel belt on the premise that the cross beam and the common pipe structure have the same strength, the wall thickness is thin, the deformation of the upper bevel edge is convenient, and the locking difficulty of a screw and a nut is reduced.

The holes in the upper bevel edge can be U-shaped holes, the U-shaped holes do not affect locking, and the upper bevel edge can be separated from the positions of the screws when impact occurs, so that the deformation capacity of the beam is further improved.

In one embodiment, the top of the upright post is provided with an end cover which seals the upright post, so that the attractiveness of the top is improved; the end cover passes through the pillar to be connected with last handrail roof beam, goes up handrail roof beam and is applicable to the bridge and uses, goes up handrail roof beam and be cylindrical, and the cable can be worn to establish in inside, and the cable gets into in the stand and gets into the below ground and pre-buries from the stand, goes up handrail roof beam surface and can set up the window, sets up the landscape lamp in the window, beautifies through carrying out the view with cable junction.

The above embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. Equivalent substitutes or changes made by the technical personnel in the technical field on the basis of the utility model are all within the protection scope of the utility model.
