Description

Technical Field

[0001] This utility model relates to the technical field of building construction, and in particular to a guardrail support for a cap beam platform. Background Technology

[0002] During bridge cap beam construction, protective netting must be installed around the operating platform to ensure the safety of construction workers. Traditional guardrail supports typically use a simple frame structure, with the protective netting tied and fixed to the support beams using metal wire. However, this method has significant drawbacks:

[0003] Metal wires are prone to displacement and detachment: During construction, personnel movement, equipment vibration, or wind can easily cause the protective net to sway repeatedly, and the metal wires under tension can easily loosen from the binding points, leading to the risk of falling objects from heights;

[0004] Uncontrolled displacement of the protective net: The existing support structure lacks an effective limiting structure, and the protective net is prone to sliding up and down along the support beam when under stress, which further aggravates the twisting deformation and detachment of the metal wires; Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a guardrail support for a cap beam platform.

[0006] This utility model provides the following technical solution: a guardrail support for a girder platform, comprising:

[0007] Two support units, which are fixedly connected to the worktable;

[0008] Two connectors are disposed between the two support units; the two connectors are respectively located on the upper and lower sides of the support unit.

[0009] The connector has several receiving grooves along its length, which are used to receive the metal wires used to bind the protective netting.

[0010] At least one of the stops is provided on the connector, and the protective net is located between the stops of the two connectors. The stops are used to restrict the vertical movement of the protective net.

[0011] Furthermore, the support unit includes:

[0012] The mounting sleeve has open ends and its sidewalls are fixedly connected to the workbench.

[0013] A support beam is inserted into the mounting sleeve and fixedly connected to the mounting sleeve.

[0014] Furthermore, the connector is I-shaped and includes: a crossbeam, mounting plates at both ends of the crossbeam, and the mounting plates are fixedly connected to the support beam.

[0015] Furthermore, the upper part of the support beam is provided with protrusions, and the adjacent protrusions of the two guardrail brackets fit together and are fixedly connected.

[0016] Furthermore, both the support beam and the connector have a hollow internal structure.

[0017] Furthermore, the support beam is provided with a plurality of threaded holes along its height direction, and the mounting plate is provided with through holes on both the upper and lower sides. Bolts are threaded through the through holes and threaded into the threaded holes to fix the mounting plate to the support beam.

[0018] Furthermore, the receiving groove formed around the outer wall of the crossbeam has an arc-shaped corner.

[0019] The beneficial effects of this utility model are as follows: by making the bottom of the protective net contact with the stop block on the lower connecting piece, the stop block on the lower connecting piece can support the protective net and prevent the protective net from moving downward; in addition, by making the top of the protective net contact with the stop block on the upper connecting piece, the stop block on the upper connecting piece can prevent the protective net from moving upward; thus, the uncontrolled displacement of the protective net can be avoided, which would lead to the twisting, deformation and detachment of the metal wire; furthermore, by placing the tied metal wire into the receiving groove, the metal wire can be prevented from shifting and falling off.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Example 1:

[0030] This utility model provides a first embodiment, which provides a guardrail bracket 2 for a cap beam platform, as shown in... Figure 1 As shown, it includes: two support units 21, two connectors 22, a receiving groove 222, and a stop block 224.

[0031] The support unit 21 is fixedly connected to the workbench 1; the connector 22 is disposed between the two support units 21; the two connectors 22 are respectively located on the upper and lower sides of the support unit 21; a plurality of receiving grooves 222 are provided along the length of the connector 22, the receiving grooves 222 are used to receive the metal wires for binding the protective net 3; at least one stop 224 is provided on the connector 22, the protective net 3 is located between the stop 224 of the two connectors 22, and the stop 224 is used to restrict the vertical movement of the protective net 3;

[0032] like Figure 3 As shown, the support unit 21 includes: a mounting sleeve 211 and a support beam 212;

[0033] The mounting sleeve 211 has open ends, and the side wall of the mounting sleeve 211 is fixedly connected to the workbench 1; the support beam 212 passes into the mounting sleeve 211 and is fixedly connected to the mounting sleeve 211.

[0034] Specifically, the mounting sleeve 211 is square in shape, with an internal cavity open at both ends. One side wall of the mounting sleeve 211 has a mounting hole that communicates with the internal cavity, allowing it to be threaded into the threaded hole 232 of the support beam 212. One outer side wall of the mounting sleeve 211 is welded to or threadedly fixed to the workbench 1. The shape and size of the support beam 212 are adapted to the internal cavity of the mounting sleeve 211, allowing it to be inserted into the sleeve. The support beam 212 has multiple threaded holes 232 evenly spaced along its height. The operator can adjust the height of the support beam 212 according to the external environment. In other words, when the guardrail bracket 2 needs to be higher to achieve a better protective effect, the support beam 212 can be mostly located in the upper part of the mounting sleeve 211. Conversely, the support beam 212 can be mostly located in the lower part of the mounting sleeve 211, so that the overall height of the guardrail bracket 2 is lower, in order to accommodate the workers' work. After the support beam 212 is inserted into the mounting sleeve 211 and the working height of the support beam 212 is adjusted, the workers can insert the bolt 231 into the mounting hole of the mounting sleeve 211 and thread it into the threaded hole 232 on the support beam 212, so that the support beam 212 is fixedly connected to the mounting sleeve 211.

[0035] like Figure 4 and Figure 5 As shown, the connector 22 includes: a crossbeam 221 and two mounting plates 223;

[0036] The crossbeam 221 is square, and mounting plates 223 are fixed at both ends of the crossbeam 221 so that the connector 22 is I-shaped. In other embodiments, the crossbeam 221 and the two mounting plates 223 are integrally formed to improve the rigidity of the connector 22.

[0037] Specifically, the mounting plate 223 has through holes on both the top and bottom sides. Bolts 231 pass through the through holes of the mounting plate 223 and are threadedly connected to the threaded holes 232 of the support beam 212, thereby fixing the mounting plate 223 to the support beam 212. That is, the mounting plate 223 at one end of the connector 22 is fixedly connected to one support beam 212 by bolts 231, and the mounting plate 223 at the other end is fixedly connected to another support beam 212 by bolts 231. Furthermore, the operator can adjust the distance between the two connectors 22 according to the usage height of the support beam 212.

[0038] like Figure 5 As shown, the crossbeam 221 of the connector 22 has several receiving grooves 222 along its length, and a stop block 224 is provided on both sides of the crossbeam 221, with the stop block 224 protruding from the outer wall of the crossbeam 221.

[0039] like Figure 4As shown, the worker can place the protective net 3 between the two connectors 22, with the bottom of the protective net 3 in contact with the stop block 224 on the lower connector 22. The stop block 224 on the lower connector 22 can support the protective net 3 and prevent it from moving downwards. Additionally, the top of the protective net 3 should contact the stop block 224 on the upper connector 22, which can prevent the protective net 3 from moving upwards. Next, the operator can use a metal wire to pass through the holes in the protective net 3 and tie it to the guardrail bracket 2, fixing the protective net 3 to the guardrail bracket. The tied metal wire is placed in the receiving groove 222. That is, after one end of the metal wire passes through the hole in the protective net 3, it then loops back from the back of the crossbeam 221 to the front, and then the two ends of the metal wire are knotted, forming a binding space inside the metal wire. The crossbeam 221 is located within the binding space, thus binding the protective net 3. The metal wire can be steel wire, iron wire, etc.

[0040] The receiving groove 222 formed around the outer wall of the crossbeam 221 has an arc angle 225 at the corner.

[0041] It is understandable that, since the tied metal wire is located inside the receiving groove 222, setting the corner of the receiving groove 222 as an arc angle 225 can prevent the metal wire from being squeezed at the corner of the receiving groove 222, resulting in excessive bending and thus breakage.

[0042] In summary, by making the bottom of the protective net 3 contact the stop 224 on the lower connector 22, the stop 224 on the lower connector 22 can support the protective net 3 and prevent the protective net 3 from moving downwards; in addition, by making the top of the protective net 3 contact the stop 224 on the upper connector 22, the stop 224 on the upper connector 22 can prevent the protective net 3 from moving upwards; thus, the uncontrolled displacement of the protective net 3 can be avoided, which would lead to the twisting, deformation and detachment of the metal wires; furthermore, by placing the tied metal wires into the receiving groove 222, the metal wires can be prevented from shifting and falling off.

[0043] like Figure 2 and Figure 3 As shown, a protrusion 213 is provided on the upper part of the support beam 212, and the adjacent protrusions 213 of the two guardrail brackets 2 fit together and are fixedly connected.

[0044] Specifically, two adjacent guardrail brackets 2 are fixedly connected by protrusions 213, which allows the two adjacent guardrail brackets 2 to be connected together to achieve better stability; the protrusions 213 are provided with threaded holes 232, and bolts 231 are screwed into the protrusions 213 of the two adjacent guardrail brackets 2 to fix the two protrusions 213 together.

[0045] Furthermore, both the support beam 212 and the connector 22 have hollow interiors; this reduces the weight of the support beam 212 and the connector 22, making it easier to transport the guardrail bracket 2 to a high altitude, that is, near the cap beam.

[0046] Example 2:

[0047] This embodiment provides a protection platform, such as Figure 2 As shown, the protective platform includes a workbench 1, and several guardrail brackets 2 as described in Embodiment 1 are arranged on the outer side of the workbench 1, and a protective net 3 is tied to the guardrail brackets 2 by metal wire; the several guardrail brackets 2 enclose a working space.

[0048] The workbench 1 includes multiple splicing plates 11 and two side plates 12; the front and rear sides of the workbench 1 are composed of multiple splicing plates 11 connected in sequence, and the left and right sides of the workbench 1 are composed of two side plates 12; the four sides of the workbench 1 are connected to each other.
