Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building guardrails, in particular to a building guardrail for municipal civil engineering. BACKGROUND

[0002] In the construction of municipal civil engineering, building guardrails are important facilities for ensuring construction safety and isolating dangerous areas. Traditional guardrails are usually simple in structure and are typically composed of vertical support columns and horizontal railings, lacking effective lateral support systems.

[0003] When the soil or fill around the construction area collapses due to rainwater immersion, loose geology, or other reasons, the lateral extrusion force generated by the collapsed soil will directly act on the guardrail. Because the traditional guardrail does not have lateral pressure-resistant structures such as diagonal bracing or reinforced foundations, the weak lateral support cannot withstand the pressure of the soil, causing the guardrail to tilt or even collapse and lose its protective function. This not only threatens the safety of construction personnel but also may cause secondary accidents, resulting in economic losses and delays in the construction schedule. In addition, the material strength of traditional guardrails is insufficient, and they are prone to rust or decay when exposed to outdoor environments for a long time, further reducing their lateral pressure resistance and failing to meet the safety protection needs of complex construction scenarios.

[0020] Please refer to Figures 1-4 As shown in the drawings, the embodiment provides a building guardrail for municipal civil engineering, which comprises a guardrail assembly 1, the guardrail assembly 1 comprises a protective fence 13, the protective fence 13 comprises two fixed columns 134, the two fixed columns 134 are fixedly connected with a fixed rod 133 on one side, the fixed rod 133 is rotationally connected with an anti-falling assembly 2, the anti-falling assembly 2 comprises a support frame 200, the support frame 200 is fixedly connected with the two fixed columns 134, the fixed rod 133 is sleeved with a support rod 201, the support rod 201 is rotationally connected with the fixed rod 133, when the guardrail assembly 1 is tilted, the support rod 201 rotates around the fixed rod 133 as the axis to support the guardrail assembly 1.

[0021] The working principle is as follows: when the soil lateral pressure causes the guardrail assembly 1 to have a tendency to fall, the support rod 201 sleeved on the fixed rod 133 automatically rotates downward around the fixed rod 133 to a vertical ground state under the action of gravity. At this time, the support rod 201, the fixed rod 133 and the fixed column 134 form a triangular support structure, which converts the tilting moment into axial stress of the support structure, the rotation angle of the support rod 201 is limited by the support frame 200, and the support angle is set to be between 60°-80°, so that the support force is transmitted to the foundation in the vertical direction. The support frame 200 not only prevents the support rod 201 from over-rotating to cause support failure, but also serves as a handle structure during transportation, realizing the combination of functionality and convenience. When the guardrail is moved to the upright state, the support rod 201 can automatically reset to the storage state due to the action of gravity, keeping the passage unobstructed.

[0022] In order to fix the protective fence 13, therefore, in the embodiment, the guardrail assembly 1 comprises a stand column 10, the two sides of the stand column 10 are fixedly connected with a lifting lug one 12 for fixing, and the lower surface of the stand column 10 is fixedly connected with a fixing seat 11. The lifting lug one 12 fixedly connected with the two sides of the stand column 10 can be used for connecting and fixing with other components, thereby enhancing the stability of the protective fence 13. The fixing seat 11 fixedly connected with the lower surface of the stand column 10 is directly in contact with the ground. The fixing seat 11 can be firmly installed on the ground by means of expansion bolts, foundation bolts and the like, so as to firmly fix the protective fence 13 at the specified position, prevent the protective fence 13 from being displaced and shaken due to external force, and ensure that the protective fence 13 can stably play a protective role during use.

[0023] In order to increase the service life of the device, therefore, in the embodiment, a plurality of cross beams 130 are fixedly connected between the two fixed columns 134, the cross beams 130 are made of hard alloy, a plurality of longitudinal beams 131 are inserted into the cross beams 130, the longitudinal beams 131 penetrate the cross beams 130, the fixed column 134 is fixedly connected with a lug 135 on one side, the cross beam 130 is made of hard alloy material and can withstand greater external force impact and is not easy to deform and damage, the longitudinal beam 131 and the cross beam 130 are connected with each other, which further enhances the stability and integrity of the entire frame structure. It can maintain good structural integrity, thereby effectively increasing the service life of the device.

[0024] In order to increase the structural strength of the anti-toppling device, therefore, in the embodiment, the support frame 200 is fixedly connected with a top rod 202 on the surface, the other end of the top rod 202 is fixedly connected with the longitudinal beam 131, and the surface of the cross beam 130 is fixedly connected with a warning sign 132 for warning effect. When the guardrail 13 is subjected to external force and has a tendency to topple, the support rod 201 in the anti-toppling assembly 2 will play a supporting role, and the triangular structure formed by the top rod 202, the support frame 200 and the longitudinal beam 131 can further enhance the structural strength of the entire anti-toppling device. The top rod 202 connects the support frame 200 and the longitudinal beam 131 together, so that they can work together to withstand external force. This structure can effectively disperse and transmit the force from the toppling direction, avoid damage to the support frame 200 or the longitudinal beam 131 due to excessive local stress, and thus ensure that the anti-toppling device can reliably play a role and enhance the anti-toppling ability of the guardrail 13.

[0025] In the embodiment, the municipal civil engineering building guardrail is used in specific use. First, the lug 12 fixedly connected on both sides of the stand column 10 is connected and fixed with the lug 135 on one side of the fixed column 134, and the fixed seat 11 fixedly connected on the lower surface of the stand column 10 is directly contacted with the ground. The fixed seat 11 can be firmly installed on the ground by expansion bolts, anchor bolts and the like, so as to firmly fix the guardrail 13 at the specified position, prevent the guardrail 13 from being displaced and shaken due to external force, and ensure that it can stably play a protective role in use.

[0026] When the soil side pressure causes the guardrail assembly 1 to have a tendency to fall, the support rod 201 sleeved on the fixed rod 133 is automatically rotated downward to the vertical ground state under the action of gravity, and when the guardrail 13 has a tendency to fall under the action of external force, the support rod 201 in the anti-falling assembly 2 will play a supporting role, and the support rod 201 will rotate due to the rotation of the guardrail 13 and the influence of its own gravity, and the triangular structure formed by the top rod 202, the support frame 200 and the longitudinal beam 131 can further enhance the structural strength of the entire anti-falling device. The top rod 202 connects the support frame 200 and the longitudinal beam 131 together, so that they can work together and jointly bear external force. This structure can effectively disperse and transmit the force from the falling direction, avoid damage to the support frame 200 or the longitudinal beam 131 due to excessive local stress, and thus ensure that the anti-falling device can reliably function, enhance the anti-falling ability of the guardrail 13, set the support angle to be between 60°-80°, and ensure that the support force is transmitted to the foundation in the vertical direction. The support frame 200 not only serves as a limiting device to prevent the support rod 201 from rotating excessively and causing support failure, but also serves as a handle structure during transportation, realizing the combination of functionality and convenience. When the guardrail is moved to the upright state, the support rod 201 can automatically reset to the storage state under the action of gravity, keeping the passage unobstructed.
