[0001] The utility model relates to the technical field of construction engineering, in particular to a safety blocking structure for bridge construction. Background Art

[0002] A bridge generally refers to a structure built across rivers, lakes, and the sea to enable vehicles and pedestrians to pass smoothly. To adapt to the modern high-speed development of the transportation industry, bridges are also extended to refer to buildings that cross mountain streams, poor geology, or meet other transportation needs to make travel more convenient. Bridges are generally composed of an upper structure, a lower structure, supports, and ancillary structures. During bridge construction, safety barrier structures are needed to warn and prevent unrelated outsiders from entering the construction site and causing safety hazards.

[0003] During the construction of bridge bearings, since the bearings are mostly located on uneven dirt roads, and most of the current blocking devices do not have the function of height and angle adjustment, it will be difficult to apply to various complex construction roads, resulting in the blocking device being unable to be stably placed on the construction road surface, affecting the blocking effect.

[0021] The support plate 1 and the telescopic connecting rod 3 form the most basic protective blocking device, and the adjustment sleeve 4 is used to install the adjustment component.

[0022] A fixing screw 5 is threadedly penetrated on the surface of the adjusting sleeve shell 4, a plurality of adjusting holes 6 are provided on the surface of the supporting plate 1, a bracket 8 is arranged below the adjusting sleeve shell 4, a connecting shell 11 is detachably connected to the surface of the bracket 8, an adjusting shell 9 is fixed on the top of the connecting shell 11, a plurality of positioning holes 10 are provided on the surface of the adjusting shell 9, a plug hole used to cooperate with the positioning holes 10 is provided on the surface of the adjusting sleeve shell 4, a connecting groove used to cooperate with the connecting plate 2 is provided on the surface of the adjusting sleeve shell 4, a fastening screw 12 is threadedly penetrated on the surface of the bracket 8, an anti-slip seat 13 is fixed at the bottom of the fastening screw 12, a fixing cone 14 is fixed at the bottom of the anti-slip seat 13, a combination shell 15 is fixed on the surface of the supporting plate 1 on one side, a connecting rod 7 is fixed on the surface of the supporting plate 1 on the other side, and an opening is provided on the surface of the combination shell 15 for inserting the connecting rod 7;

[0023] When the soil at the bottom of one side of the bracket 8 is higher or lower than the soil height at the bottom of the other side of the bracket 8, the overall height of the bracket 8 can be changed by sliding the adjustment sleeve 4, so as to adapt to the road surface with different soil heights on both sides, to prevent the safety hazard caused by the gap at the bottom of the bracket 8 due to the height difference, or the problem that the guardrail cannot play a good protective effect by tilting. When the slopes of the roads on both sides are different, the bolts fixed at the positioning holes 10 on the surfaces of the adjustment sleeve 4 and the adjustment shell 9 can be removed, and then the bracket 8 can be rotated so that the bottom of the bracket 8 can fit the slope of the road surface, and then the adjustment sleeve 4 can be re-positioned by passing the bolts through the positioning holes 10 and the plug hole to fix the bracket 8, so as to allow the guardrail to be installed on different slopes. The guardrail can maintain a stable and vertical state on the ground with different degrees, undulations and unevenness, and can ensure the effectiveness and safety of the guardrail even in bridge construction, road construction or other complex terrain environments. After adjusting the angle and height of the bracket 8, rotating the fastening screw 12 can make the fixing cone 14 inserted into the soil, thereby providing a better anchor effect, making the bracket 8 more stable when encountering wind, rain, vibration and other external forces, and not prone to shaking or collapse. When the two guardrails are connected, the connecting rod 7 on the surface of the support plate 1 on one side is clamped into the inside of the combination shell 15 through the opening on the surface of the combination shell 15, so that the combination between the two guardrails can be quickly completed, and the angle between the two guardrails can be conveniently adjusted to meet various protection needs.

[0026] Furthermore, the support plate 1, the adjustment sleeve shell 4 and the bracket 8 are all made of aluminum alloy, and the combined shell 15 is made of plastic;

[0027] The aluminum alloy material has the advantages of high strength and light weight, and it can well meet the protection and mobility requirements of the guardrail, while the combined shell 15 made of plastic material ensures that it can be deformed so that the connecting rod 7 can pass through the opening normally.

[0028] Furthermore, the thread on the surface of the combined shell 15 penetrates the limiting screw 16;

[0029] After adjusting the rotation angle between the two guardrails, tightening the limit screw 16 can limit the connection rod 7, thereby preventing the two guardrails from rotating.

[0030] Furthermore, a plurality of connection holes 19 are provided on the surfaces of the connection shell 11 and the bracket 8, and the connection shell 11 and the bracket 8 are detachably connected by bolts through the connection holes 19;

[0031] The connecting shell 11 can be disassembled from the bracket 8, so that the device can save more space when carried.

[0032] Furthermore, the adjustment shell 9 is arranged in a semicircular structure, and the positioning holes 10 are arranged in a circular array on the surface of the adjustment shell 9;

[0033] The adjusting sleeve 4 can have a wider angle adjustment range through the positioning holes 10 distributed in an annular manner.

[0034] Furthermore, a plurality of rubber strips are fixed to the bottom of the anti-slip seat 13;

[0035] The rubber strip can increase the friction between the bottom of the anti-slip seat 13 and the ground, thereby improving the stability of the protective device.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
