Description

Scalable standardized frontier defense guardrail of adjusting

Technical Field

The utility model belongs to building auxiliary assembly relates to a scalable standardized frontier defense guardrail of adjusting.

Background

The side opening forms of construction sites in the building industry are various, the sizes are different, the operation work is multiple, the mobility of personnel is high, the self-protection consciousness is poor, and the side opening form-changing device belongs to the high-release industry of safety accidents, and particularly frequent high-altitude falling accidents. At present, most of sites using the temporary edge protection are temporary edge protection built by steel pipes, the steel pipes are small in size and specification, the reinforcement is very inconvenient, the impact resistance cannot meet the standard requirement, the phenomenon of personal dismantling of workers is more, and the difficulty in recovering and supervising afterwards is high. The size of the edge steel pipe is small, the occupied capital cost is high, the waste is serious, and the material turnover is difficult due to different sizes. In summary, it is desirable to use a temporary edge protection material that is simple and easy to install, flexible and variable in size, high in turnover efficiency, and low in cost. Although standard part construction is carried out to a certain extent in the existing edge-facing protection erection, the size is single, the variable sizes of a construction site cannot be met, the size combination is inflexible, most of the existing edge-facing protection erection equipment cannot be matched with the size of a hole, local dismantling is easy, and great potential safety hazards are caused on the construction site.

Disclosure of Invention

An object of the utility model is to solve the above-mentioned problem, provide but have combination convenience, size flexibility, can freely adjust size, simple to operate nimble nevertheless demolish difficulty, reduce characteristics such as potential safety hazard at will that scalable regulation is standardized faces frontier defense guardrail.

The utility model aims at realizing that a scalable regulation standardization faces frontier defense guardrail, including square pipe, pole setting, safe fender sole and ground steel sheet, select two kinds of square pipes for use, square pipe A specification is 25 × 40 × 3 mm, length 2000 mm, square pipe B specification is 20 × 30 × 3 mm, length 1000 mm, square pipe A overlaps outside square pipe B, square pipe A and square pipe B butt joint department are with two more than Ø 8 50 bolt fastening, bolt fastening interval is 200mm, nut side pipe welding is on A, square pipe B has beaten a plurality of Ø 10 mm's eye in advance, square pipe A and square pipe B's both ends and the pole setting welded fastening of both sides, the pole setting height is 1200 mm, the pole setting lower extreme is fixed subaerial with 150 × 80 ground steel sheet and inflation screw, be equipped with the safe fender sole that height is 180 mm between bottom square pipe A and the ground, the sole is with the bolt fastening for the safe fender sole that blocks.

Drawings

The present invention will be further explained with reference to the accompanying drawings.

Fig. 1 is an installation schematic diagram of the present invention.

Detailed Description

As shown in the attached drawing, the telescopic and adjustable standardized frontier defense guardrail comprises a square pipe, a vertical rod, a safe foot baffle plate and a ground connecting steel plate.

Two square tubes are selected, the square tube A1 is 25 × 40 × 3 mm in specification and 2000 mm in length, the square tube B2 is 20 × 30 × 3 mm in specification and 1000 mm in length, and the square tube A1 is sleeved outside the square tube B2.

The butt joint of the square pipe A1 and the square pipe B2 is fixed by more than two Ø 8 x 50 bolts 6, the fixing distance of the bolts 6 is 200mm, the nuts are welded on the square pipe A1, and a plurality of Ø 10mm holes are drilled in the square pipe B2 in advance.

The two ends of the square tube A1 and the square tube B2 are welded and fixed with the upright stanchions 3 at the two sides, the height of the upright stanchions 3 is 1200 mm, and the lower ends of the upright stanchions 3 are fixed on the ground by 150-80 ground connecting steel plates 5 and expansion screws.

A safety foot-blocking plate 4 with the height of 180 mm is arranged between the bottom square tube A1 and the ground, and the bottom square tube A1 and the safety foot-blocking plate 4 are fixed through bolts.

The utility model discloses can freely adjust the size by square pipe A1 cover at square pipe B2's length decision, can freely adjust the size to be 800 mm under above specification condition.

The utility model discloses a material of different specifications is applied mechanically, is processed into pieces, is assembled into pieces, and fundamentally has solved current border protection guardrail size unadjustable, factor of safety is low, shock resistance subalternation problem. The adjustable size of the frontier defense guardrail, convenient combination, flexible size, convenient and flexible installation, difficult random dismantling and the like are added on the basis of standardized construction, and the potential safety hazard risk caused by random dismantling of original workers is greatly reduced.

The utility model discloses can process in batches at the processing factory, standardized construction degree is high.
