Description

Technical Field

[0001] The utility model relates to the field of protective railings, in particular to a protective railing for building construction. Background Art

[0002] The anti-fall fence used in high-rise building construction is a protective facility to prevent personal injury at the construction site. It is suitable for safety protection in all types of construction sites. The eye-catching color markings can serve as an advance warning to workers that they should pay attention to safety in dangerous places. It is an indispensable construction net for each construction site.

[0003] Existing building construction guardrails are generally improved for convenience in use. For example, a building construction guardrail disclosed in the authorized Chinese patent CN212428148U can be used in combination with structures such as a base plate, a limit hole, a pointed bolt and a pressure plate to effectively fix the guardrail on the ground. It has high stability and can effectively improve the protection effect. At the same time, the base plate can be raised by the combination of structures such as a support plate, a limit plate, a base plate, a mounting block, a universal wheel, a through hole, a first screw rod, a second screw rod, a moving block, a transmission rod and a slide groove until the universal wheel supports the ground. The guardrail can be moved by pushing, which is convenient to move and has high convenience. However, the technical solution of the building construction guardrail does not have the function of anti-collision and buffering when in use. Once it encounters an external force impact, it will cause large-scale deformation and damage of the entire guardrail, thereby resulting in the anti-collision effect of the existing building construction guardrail to be improved. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a building construction guardrail, which has the advantages of being able to effectively improve the anti-collision effect of existing building construction guardrails, and solves the problem of poor anti-collision effect of existing building construction guardrails.

[0005] In summary, the utility model provides the following technical solutions: a guardrail for construction of buildings, comprising two mounting bases, the mounting bases being fixed to the ground by bolts, an anti-collision mechanism being installed between the tops of the two mounting bases to effectively decompose the external impact force when a collision occurs, the anti-collision mechanism being able to return to its original state after the impact force ends, so as to prevent the guardrail from tipping over or being damaged due to a collision;

[0006] The anti-collision mechanism includes a support column fixedly installed on the top of the mounting base plate, two symmetrical horizontal fixing blocks are fixedly installed between opposite sides of the two support columns, and vertical rods arranged equidistantly are fixedly installed between opposite sides of the two horizontal fixing blocks to enhance the stability of the support of the horizontal fixing blocks. A reflective warning component is installed on the side of the top horizontal fixing block away from the bottom horizontal fixing block, which can reflect the surrounding light at night to warn passers-by and drivers. The front of the horizontal fixing block is provided with equidistantly arranged grooves, and the inner side of the groove is slidably connected with two symmetrical moving components, and the left and right inner walls of the groove are provided with adjustment grooves for the sliding of the moving components. An impact sliding component is installed between opposite sides of the two moving components, and two elastic guide components symmetrically installed between one side of the back of the moving component and the inner rear side wall of the groove are used to alleviate the impact force when a collision occurs.

[0007] Furthermore, the reflective prompt component includes a support block, a fixing plate and a reflective strip; one end of the two support blocks is fixedly connected to the top horizontal fixing block, and the other end is fixedly connected to one side of the fixing plate close to the vertical rod, and the reflective strip is fixedly connected to the front side of the reflective strip.

[0008] By adopting the above technical solution, the supporting block, the fixing plate and the reflective strip cooperate with each other to reflect the surrounding light at night, thereby playing a certain warning role for passers-by and drivers.

[0009] Furthermore, the moving assembly includes a moving block and two adjusting blocks; the outer side of the moving block slides in contact with the inner side of the groove, and the left and right sides of the moving block are fixedly connected with adjusting blocks that slide in contact with the inner side of the adjusting groove.

[0010] By adopting the above technical solution, the cooperation of the moving block and the two adjusting blocks can make the moving block more stable when moving forward and backward, and at the same time, the moving distance of the moving block is limited.

[0011] Furthermore, the impact sliding assembly includes a rotating rod and a pulley; the two opposite sides of the two moving blocks are rotatably connected to the two ends of the rotating rod through bearings, and the outer side of the rotating rod is fixedly connected to the inner side of the pulley.

[0012] By adopting the above technical solution, under the cooperation of the rotating rod and the pulley, the guardrail can have a certain buffering effect when a collision occurs, thereby effectively decomposing the external impact force.

[0013] Furthermore, the diameter of the pulley is smaller than the length of the moving block.

[0014] The above technical solution is adopted to prevent the pulley from being unable to rotate in the groove.

[0015] Furthermore, the elastic guide assembly includes a telescopic rod and a spring; one end of the telescopic rod is fixedly connected to the moving block, and the other end is fixedly connected to the inner rear side wall of the groove, and the outer side of the telescopic rod is sleeved with a spring for elastic energy storage and rebound force.

[0016] By adopting the above technical solution, the telescopic rod and the spring cooperate to prevent collision and absorb the impact force when the guardrail is hit.

[0018] By adopting the above technical solution, the moving block can be pushed back to its original position under the action of the elastic potential energy return force of the spring when the moving block is moved.

[0019] Compared with the prior art, the utility model provides a construction guardrail for building, which has the following beneficial effects:

[0020] The building construction guardrail can provide a function that can effectively decompose external impact force when a collision occurs through the mutual cooperation between the anti-collision mechanisms installed on the bottom plate, so that the building construction guardrail has a certain buffer effect, and after the impact force ends, it can be restored to its original state, which can effectively prevent the guardrail from tipping over or being damaged due to the collision. In this way, the guardrail can prevent and absorb the impact force when it is hit, thereby effectively improving the anti-collision effect of the existing building construction guardrail.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-4 The utility model provides a technical solution: a construction guardrail for building, comprising two mounting base plates 1, the mounting base plates 1 being fixed to the ground by bolts, an anti-collision mechanism 200 which can effectively decompose the external impact force when a collision occurs is installed between the tops of the two mounting base plates 1, and the anti-collision mechanism 200 can be restored to its original state after the impact force ends, so as to prevent the guardrail from being overturned or damaged due to the collision;

[0029] By using the anti-collision mechanism 200 installed on the base plate 1 in coordination with each other, a function that can effectively decompose the external impact force can be provided when a collision occurs, so that the building construction guardrail has a certain buffering effect, and after the impact force ends, it can be restored to its original state, which can effectively prevent the guardrail from tipping over or being damaged due to the collision. In this way, the guardrail can prevent and absorb the impact force when it is hit, thereby effectively improving the anti-collision effect of the existing building construction guardrail.

[0030] In this embodiment, the anti-collision mechanism 200 is a structure that can effectively decompose external impact force when a collision occurs.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the anti-collision mechanism 200 includes a support column 201 fixedly installed on the top of the mounting base plate 1, two symmetrical horizontal fixing blocks 202 are fixedly installed between the opposite sides of the two support columns 201, and a vertical rod 203 arranged equidistantly is fixedly installed between the opposite sides of the two horizontal fixing blocks 202 to enhance the stability of the support of the horizontal fixing blocks 202. A reflective prompt component is installed on the side of the top horizontal fixing block 202 away from the bottom horizontal fixing block 202, which can reflect the surrounding light at night to warn passers-by and drivers. The front of the horizontal fixing block 202 is provided with equidistantly arranged grooves 205, and the inner side of the groove 205 is slidably connected with two symmetrical moving components, and the left and right inner side walls of the groove 205 are provided with adjustment grooves 207 for the moving components to slide. An impact sliding component is installed between the opposite sides of the two moving components, and two symmetrical elastic guide components are installed between one side of the back of the moving component and the inner rear side wall of the groove 205 to alleviate the impact force when a collision occurs.

[0032] It should be noted that the reflective warning assembly includes a support block 2041, a fixing plate 2042 and a reflective strip 2043; one end of the two support blocks 2041 is fixedly connected to the top horizontal fixing block 202, and the other end is fixedly connected to the side of the fixing plate 2042 close to the vertical rod 203, and the reflective strip 2043 is fixedly connected to the front side of the reflective strip 2043 in order to reflect the surrounding light at night, thereby playing a certain warning role to passers-by and drivers.

[0033] It can be understood that the moving assembly includes a moving block 2061 and two adjusting blocks 2062; the outer side of the moving block 2061 slides in contact with the inner side of the groove 205, and the left and right sides of the moving block 2061 are fixedly connected with the adjusting blocks 2062 that slide in contact with the inner side of the adjusting groove 207, in order to make the moving block 2061 more stable when moving forward and backward, and also to limit the moving distance of the moving block 2061.

[0034] In addition, the impact sliding assembly includes a rotating rod 2081 and a pulley 2082; the two opposite sides of the two moving blocks 2061 and the two ends of the rotating rod 2081 are rotatably connected through bearings, and the outer side of the rotating rod 2081 is fixedly connected to the inner side of the pulley 2082, so that the guardrail has a certain buffering effect when a collision occurs, thereby effectively decomposing the external impact force.

[0035] In this embodiment, the diameter of the pulley 2082 is smaller than the length of the moving block 2061 in order to prevent the pulley 2082 from being unable to rotate in the groove 205 .

[0036] It should also be noted that the elastic guide assembly includes a telescopic rod 2091 and a spring 2092; one end of the telescopic rod 2091 is fixedly connected to the moving block 2061, and the other end is fixedly connected to the inner rear side wall of the groove 205, and the outer side of the telescopic rod 2091 is sleeved with a spring 2092 for elastic energy storage and rebound force, so as to prevent collision and absorb impact force when the guardrail is hit.

[0037] It should be further explained that the natural width of the spring 2092 is equal to the width of the groove 205 so that when the moving block 2061 is moved, the moving block 2061 can be pushed back to its original position under the action of the elastic potential energy of the spring 2092 .

[0038] The working principle of the above embodiment is:

[0039] When the guardrail collides, the pulley 2082 contacts the object first when it is impacted, and the pulley 2082 rotates in the groove 205. The impact object will deviate as the pulley 2082 rotates. The rotation of the pulley 2082 and the impact object can remove part of the impact force on the guardrail, avoiding direct collision, which is safer. After the pulley 2082 contacts the impact object, it will push the pulley 2082 to move toward the direction close to the inner rear side wall of the groove 205, and at the same time drive the moving block 2061 to move toward the direction close to the inner rear side wall of the groove 205. Because the moving block 2061 only moves in the direction close to the inner rear side wall of the groove 205 under the sliding connection cooperation between the adjustment block 2062 and the adjustment groove 207, It can move in the groove 205, and the telescopic rod 2091 and the spring 2092 are squeezed by the pressing force of the moving block 2061 to shrink. The telescopic rod 2091 is completely shrunk. The guardrail is lighter than the impactor. The spring 2092 resets and pushes the moving block 2061 to move. The pulley 2082 moves accordingly and bounces the impactor away, thereby minimizing the impact force on the guardrail. In this way, the guardrail can prevent and absorb the impact force when it is hit. At the same time, the support block 2041, the reflective strip 2043 and the reflective strip 2043 cooperate with each other to reflect the surrounding light at night, thereby providing a certain warning to passers-by and drivers.

[0040] Compared with the prior art: the building construction guardrail, through the mutual cooperation between the anti-collision mechanism 200 installed on the base plate 1, can provide a function that can effectively decompose the external impact force when a collision occurs, so that the building construction guardrail has a certain buffering effect, and after the impact force ends, it can be restored to its original state, which can effectively prevent the guardrail from tipping over or being damaged due to the collision, so that the guardrail can prevent and absorb the impact force when it is hit, thereby effectively improving the anti-collision effect of the existing building construction guardrail, and solving the problem of poor anti-collision effect of the existing building construction guardrail.
