Description

Technical Field

[0001] The utility model relates to an adjustable safety guardrail for cap beam shim construction, belonging to the field of high-altitude operation safety protection for bridge shim construction. Background Art

[0002] Bridge bearings are crucial structural components connecting the bridge's superstructure and substructure. Located between the bridge and the pier, bridge bearings are installed on the piers, supporting the bridge's superstructure from their top surface. Their function is to withstand the various forces acting on the superstructure and reliably transmit them to the piers, making them a crucial force-transmitting device for bridges. In recent years, with the rapid development of highway and municipal engineering projects, bridge construction has become increasingly popular, and the construction technology for bridge bearing piers has matured, meeting all operational requirements.

[0003] However, during the construction of conventional support pedestals, the guardrails and the cap beams are mostly connected together by flat belts to protect the construction workers and ensure their safety. However, most existing guardrails are connected by several horizontal bars and several vertical bars, and a large space is created between the horizontal bars and the vertical bars. During the construction process, small objects on the work surface can easily fall through the space between the horizontal bars and the vertical bars, thereby affecting use. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide an adjustable cap beam shim construction safety guardrail.

[0005] In order to achieve the above purpose, the present invention is implemented through the following technical solutions:

[0006] The lifting link jack is connected with the support frame of the lifting post by the spring, and the lifting link jack is connected with the support frame by the spring.

[0007] Furthermore, the storage mechanism includes a rotating rod rotatably connected to the inside of the storage box, the outer surface of the rotating rod is fixedly connected to a winding cloth, the winding cloth is wrapped around the surface of the rotating rod, the other end of the winding cloth passes through the outside of the storage box and is fixedly connected to the mounting sleeve, and an opening is provided on one side of the outer surface of the storage box, and the winding cloth passes through the opening.

[0008] Furthermore, a coil spring is installed at one end of the storage box, and the front end of the rotating rod passes through the storage box and is fixedly connected to the coil spring.

[0009] Furthermore, the fixing mechanism includes a fixing block fixed to the top of the cross bar 4, a fixing cavity is provided at the top of the fixing block, a movable groove is provided on the inner walls on both sides of the fixed cavity, a stopper is slidably connected to the inside of the movable groove, one end of the stopper is connected to the inner wall of the movable groove by a spring, and the other end of the stopper passes through the movable groove and extends into the fixed cavity.

[0010] Furthermore, the top of the block is an inclined slope, a movable block is fixed on the top of the block, the top of the movable block passes through the top of the fixed block, and through holes connected to the movable groove are respectively opened on both sides of the top of the fixed block.

[0011] Furthermore, the bottom cross brace is located on the top surface of the cap beam.

[0012] Beneficial effects of the utility model:

[0013] By setting up the storage mechanism, the space between the horizontal bar and the vertical bar on the side guardrail can be shielded and protected to prevent tools from falling from the gap between the horizontal bar and the vertical bar, affecting their use.

[0014] Through the setting of the fixing mechanism, when the installation sleeve moves out of the cross bar, the fixing mechanism can limit the position of the installation sleeve, and then limit the unfolded roll-up cloth, so that the roll-up cloth can always be in the unfolded state during the construction process, which is convenient for use.

[0015] By setting up flat belts and flat belt tensioners, the side guardrails on both sides are bundled with the cap beam to form a whole, thereby improving the overall stability and impact resistance of the guardrail. The side guardrails extend below the top surface of the cap beam and are fixed to the side of the cap beam by flat belts. The entire guardrail is supported by the flat belts set at the bottom to hold the bottom of the cap beam. The side guardrails and the cap beam are bundled together to form a whole by the flat belt tensioners, thereby improving the anti-overturning performance of the guardrail. The number of flat belts is set according to actual needs.

[0016] By setting up the flat belt and fixing it with the flat belt, the concrete protective layer at the corner of the cap beam can be protected from being damaged.

[0017] This device makes the guardrail width adjustable to accommodate cap beams of different widths by designing the top and bottom cross braces to be telescopic. At the same time, during the construction process, the device ensures the life safety of workers in the paving stone construction, eliminates safety hazards, and reduces the accident rate.

[0018] The top cross brace is designed to be sliding, and its position can be adjusted during construction to avoid affecting the pouring of pad stone concrete.

[0019] The bottom cross brace is designed to be sliding, which can flexibly avoid the position of the pad stone and facilitate construction. The bottom cross brace 9 can rotate along the vertical direction of the guardrail. The purpose is to allow the guardrails on both sides to be close together when the guardrail is assembled on the ground, avoiding deformation of the guardrail during lifting. At the same time, when the side guardrail is lifted to the top of the cap beam, it is convenient to open and clamp both sides of the cap beam for easy installation. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1-9 The utility model provides a technical solution for an adjustable safety guardrail for construction of a cap beam and a bolster stone. The adjustable safety guardrail for construction of a cap beam and a bolster stone comprises two side guardrails and a cap beam. The two side guardrails are connected to the cap beam by a flat belt 10. The flat belt 10 is provided with a flat belt tightener. The side guardrails comprise a crossbar 1, a crossbar 2, a crossbar 3 and a crossbar 4. The crossbar 1 is 1.2 meters away from the top surface of the cap beam, the crossbar 2 is 60 centimeters away from the top surface of the cap beam, the crossbar 3 is flush with the top surface of the cap beam, and the crossbar 4 can be designed to be 50 centimeters away from the top surface of the cap beam to the bottom of the cap beam. Each section of the guardrail is connected by pinning. The crossbar 1, the crossbar 2, the crossbar 3 and the The four cross bars 4 are connected by several vertical bars 5. A top sliding connector 6 is provided on the cross bar 1 on both sides, and a top cross brace 7 is connected between the two top sliding connectors 6. A bottom sliding connector 8 is provided on the cross bar 3 on both sides, and a bottom cross brace 9 is connected between the two bottom sliding connectors 8. The bottom cross brace 9 is located on the top surface of the cap beam. Several accommodating cavities 11 are provided at the bottom of the cross bar 1, and a storage box 12 is fixed inside the accommodating cavity 11. A winding cloth 15 is connected to the storage box 12 through a storage mechanism. The top of the cross bar 4 is provided with a fixing mechanism that cooperates with the winding cloth 15.

[0033] SeeFigure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The storage mechanism includes a rotating rod 13 rotatably connected to the inside of the storage box 12, and the outer surface of the rotating rod 13 is fixedly connected to a winding cloth 15, and the winding cloth 15 is wrapped around the surface of the rotating rod 13, and the other end of the winding cloth 15 passes through the outside of the storage box 12 and is fixedly connected to the mounting sleeve 16. An opening 17 is provided on one side of the outer surface of the storage box 12, and the winding cloth 15 passes through the opening 17. A coil spring 14 is installed at one end of the storage box 12, and the front end of the rotating rod 13 passes through the storage box 12 and is fixedly connected to the coil spring 14. Through the setting of the storage mechanism, the space between the horizontal bar and the vertical bar 5 on the side guardrail can be shielded and protected to prevent tools from falling from the gap between the horizontal bar and the vertical bar 5, affecting use.

[0034] See Figure 8 and Figure 9 The fixing mechanism includes a fixing block 18 fixed to the top of the cross bar 4, and a fixing cavity 19 is opened on the top of the fixing block 18. A movable groove 21 is opened on the inner walls of the fixing cavity 19 on both sides. A stopper 20 is slidably connected to the inside of the movable groove 21, and one end of the stopper 20 is connected to the inner wall of the movable groove 21 by a spring 22. The other end of the stopper 20 passes through the movable groove 21 and extends into the fixing cavity 19. The top of the stopper 20 is an inclined slope. A movable block 23 is fixed to the top of the stopper 20, and the top of the movable block 23 passes through the top of the fixing block 18. Through holes 24 connected to the movable groove 21 are opened on both sides of the top of the fixing block 18. Through the setting of the fixing mechanism, when the installation sleeve 16 moves out of the cross bar 1, the fixing mechanism can limit the position of the installation sleeve 16, and then limit the reeling cloth 15 after unfolding, so that the reeling cloth 15 can always be in the unfolded state during construction, which is convenient for use.

[0035] When in use, first assemble the side guardrail on the ground, that is, install the bottom support 9 of the side guardrail on the ground, then support the top of the two side guardrails together and hoist them to the top of the cap beam, adjust the support to avoid the position of the pad stone, and clamp the side guardrails on both sides of the cap beam, then install the top cross brace 7 and the flat belt 10, tighten the flat belt 10 with the flat belt tightener to fix the guardrail, and the installation of the entire guardrail can be completed.

[0036] When workers are working on the construction, they can pull the reeling cloth 15 open in advance to shield and protect the space between the cross bar and the vertical pole 5 on the entire guardrail to prevent tools from falling from the space between the cross bar and the vertical pole 5. That is, by pulling the installation sleeve 16 at the bottom of the cross bar 1, the installation sleeve 16 moves and pulls the reeling cloth 15. As the installation sleeve 16 continues to move, the reeling cloth 15 will unfold and cover the space between the cross bar and the vertical pole 5. Then, it drives the installation sleeve 16 to squeeze into the inside of the fixed block 18. As the installation sleeve 16 moves downward, it squeezes the stoppers 20 on both sides of the top of the fixed block 18. The two stoppers 20 move to the outside of the two ends of the fixed block 18 respectively. As the mounting sleeve 16 moves into the fixed cavity 19, at this time, there is no squeezing of the mounting sleeve 16, and the blocks 20 on both sides return to their original positions and are located above the mounting sleeve 16, thereby limiting the position of the mounting sleeve 16. When the mounting sleeve 16 needs to be removed to roll the winding cloth 15 back into the storage box 12, at this time, the two moving blocks 23 can be moved toward both sides of the fixed block 18. The two moving blocks 23 respectively drive the blocks 20 connected to each other to move toward both sides of the fixed block 18, and the blocks 20 on both sides return to the movable groove 21 at the same time. At this time, the mounting sleeve 16 is moved upward, and under the action of the coil spring 14, the winding cloth 15 is rolled back on the outer surface of the rotating rod 13.

[0037] When it is necessary to dismantle, first remove the top cross brace 7, open the flat belt tightener, lift the two side guardrails together to the ground, and then dismantle the bottom support 9. It can also be installed and dismantled in sections.

[0038] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
