Description

Interim guardrail of hem formula engineering

Technical Field

The utility model relates to an engineering guardrail, especially an interim guardrail of hem formula engineering.

Background

At the construction site of road periphery or being close to the stream of people, often need put interim guardrail at construction area periphery to marking off forbidden region and playing the warning effect, avoid outside crowd to miss to go into and cause unnecessary damage. Current interim guardrail generally forms by the pipe welding, and the guardrail middle part forms the block net structure and prevents that personnel from strideing across or boring into, and the guardrail both ends are supported through the supporting legs, and guardrail length sets up at 1 ~ 5 meters according to different specifications and varies. However, the engineering guardrails of this kind have the defect that when the engineering guardrails are arranged, since each engineering guardrail is of a single-body structure and adjacent guardrails cannot be connected, external personnel can easily move away one end of the engineering guardrail and enter the engineering guardrail from a gap, so that the intercepting effect on the external personnel is poor and only a warning effect is achieved.

Aiming at the problem, the existing solution methods are divided into two methods, the first method is to set inserting structures on two sides of adjacent engineering guardrails according to the structure of the road guardrail, so that the engineering guardrails can be inserted and fixed in sequence, and the manual removal of a single engineering guardrail is avoided; however, the structure can only be applied to a linear arrangement mode, and once the engineering guardrails are required to be placed along curves, the inserting parts of the adjacent engineering guardrails can be staggered with each other and collide and interfere at the positions of the supporting feet, so that certain limitation exists. The second is that after the engineering guardrails are arranged and placed, the adjacent engineering guardrails are bound by a binding belt or a rope, so that the movement of a single engineering guardrail is prevented. Although the mode can not influence the arrangement angle of the engineering guardrail, the binding structure is easy to collapse or fall off when the engineering guardrail is shaken artificially, and the limiting effect is unstable.

Therefore, an engineering guardrail capable of being connected with each other and adjusting the placing angle is needed.

SUMMERY OF THE UTILITY MODEL

Detailed Description

The present invention will be further described with reference to the drawings and examples, which should not be construed as a limitation to the present invention.

Examples are given. The utility model provides an interim guardrail of hem formula engineering, constitutes as shown in figure 1, includes the guardrail body 1 that forms by the welding of a plurality of pipes, and the pipe downwardly extending at guardrail body 1 both ends forms supporting part 2, and the lower extreme of supporting part 2 is connected with supporting legs 3, its characterized in that: be equipped with rotatable coupling's rotation groove 4 and dwang 5 on the pipe at 1 both ends of guardrail body, 2 inboard supporting parts that are close to dwang 5 one end are equipped with fixation nut 6, and the supporting part 2 is connected through 7 locks of intubate to 3 upper ends of supporting legs of fixation nut 6 below, and sliding connection has clamping screw 8 on 3 supporting legs of 7 below intubate, and 7 and threaded connection fixation nut 6 of intubate are passed to clamping screw 8's upper end.

A round hole for the fixed screw 8 to pass through is arranged on the supporting leg 3 close to one end of the rotating rod 5.

Be connected with the welded tube on the pipe of 1 one end of guardrail body, the hole of welded tube forms rotation groove 4, the appearance of dwang 5 appears for L, and one side of dwang 5 extends to in the rotation groove 4.

The insertion tube 7 is rotatably connected with the support part 2, and a gap is reserved between the upper end of the insertion tube 7 and the fixing nut 6.

The supporting legs 3 are C-shaped, the inner sides of the supporting legs 3 form an operation opening for workers to extend into the inner hexagonal wrench and operate, and the supporting legs 3 can be formed by bending steel pipes.
