Description

Face frontier defense guardrail in construction

Technical Field

The utility model relates to a building engineering technical field, especially an face frontier defense guardrail in construction.

Background

In a construction site, when no protective facilities are arranged at the edge of a working face or the height of the protective facilities is less than 0.8 m, the edge-facing operation is carried out. In the construction process, each construction worker faces the safety problem of 'four-opening and five-edge'. The four openings refer to a stair opening, an elevator opening, a reserved hole opening and a passage opening; the five adjacent edges refer to the periphery of a balcony, the periphery of a floor, the periphery of a roof, the side edges of a runway and a chute and the side edge of a discharging platform; these near-edge openings are all dangerous sources of high-altitude falling accidents.

The traditional near-edge cave entrance guard railing is constructed temporarily and is constructed in a near-edge cave entrance corridor, so that the width of the corridor is reduced, and constructors cannot pass through the corridor easily; in addition, unnecessary troubles and inconvenience are brought to later-stage building construction. Along with the working procedures of masonry construction of secondary structural engineering, plastering and putty scraping of decoration and finishing engineering, cleaning work and decoration of bay windows, air-conditioning plates and the like of external walls, the guard railing of the adjacent edge opening needs to be detached from time to time, and needs to be restored afterwards. Different processes, different time, the installation of protection railing is demolishd, and not only the time and the work of wasting time are not resumeed after the rail guard is disassembled at will sometimes moreover, just can make and face the limit entrance to a cave and lose the protection, buries down hidden danger for the safety construction.

Disclosure of Invention

In order to overcome the problems, the utility model aims to provide an edge guard fence is faced in construction, this rail guard sets up and faces limit entrance to a cave inboard, and the construction need not often be demolishd like this, and it is more convenient to operate.

The utility model discloses a following scheme realizes: a limb guardrail in building construction comprises at least three vertical rods, wherein the three vertical rods are sequentially arranged from left to right, angle irons are arranged at the upper end and the lower end of the front of each vertical rod, the vertical rods are fixed on the inner side of a shear wall in building construction through the angle irons, a plurality of protective components are transversely arranged on the three vertical rods, each protective component comprises a first transverse rod, a second transverse rod and a third transverse rod which are sequentially arranged from top to bottom, a distance is reserved among the first transverse rod, the second transverse rod and the third transverse rod, the first transverse rod and the third transverse rod are transversely arranged on the three vertical rods, a plurality of groups of clamping components are arranged on the front faces of the three vertical rods, the number of the clamping components is the same as that of the protective components, each group of clamping components comprises three clamping pieces, each clamping piece comprises a vertical plate and an L-shaped limiting plate, the vertical plates are fixed on the front faces of the vertical rods, the L-shaped limiting plate is perpendicularly connected with the bottom of the vertical plate, the tail end of the L-shaped limiting plate is tilted outwards, a protruding portion is arranged on the inner side of the L-shaped limiting plate, concave portions are arranged at the left end, the middle portion and the right end of the second transverse rod and matched with the protruding portions, and the second transverse rod is erected on three clamping pieces of the three vertical rods.

Furthermore, one end of the angle iron is welded on the vertical rod, and the other end of the angle iron is fixed on the wall of the scissors through an expansion screw.

Further, the first cross rod and the third cross rod are transversely welded or fixed on the three vertical rods through bolts.

The beneficial effects of the utility model reside in that: set up the rail guard in facing limit entrance to a cave inside, the rail guard can not occupy the space that faces limit entrance to a cave corridor like this, and secondary structure engineering's brickwork is built by laying bricks or stones, the operation of plastering, puttying is to facing the limit entrance to a cave outside and going on, can not demolish the rail guard like this, demolish again when needs are to facing limit entrance to a cave inside construction, just the utility model discloses a second horizontal pole can be followed the rail guard and lift off or install, and it is also very convenient when needing to face limit entrance to a cave inside construction operation like this, has improved the security of construction.

Detailed Description

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

Please refer to fig. 1 to 3, the utility model relates to a face frontier defense guardrail in construction, including three piece at least vertical poles 1, three vertical poles 1 set gradually from a left side to the right side, and the positive upper and lower both ends of vertical pole 1 all are provided with an angle bar 11, vertical pole 1 passes through angle bar 11 to be fixed at construction's scissors wall (not shown) inboard, owing to set up the rail guard in facing frontier opening inboard, the rail guard can not occupy the space that faces frontier opening corridor like this, and the masonry of secondary structure engineering is built by laying bricks or stones, is decorated the decoration engineering, the operation of scraping putty is all to facing frontier opening outside and is gone on, can not demolish the rail guard like this. The three vertical rods 1 are transversely provided with a plurality of protection components 2, each protection component 2 comprises a first transverse rod 21, a second transverse rod 22 and a third transverse rod 23 which are sequentially arranged from top to bottom, a distance d is reserved between each first transverse rod 21, each second transverse rod 22 and each third transverse rod 23, the first transverse rods 21 and the third transverse rods 23 are transversely arranged on the three vertical rods 1, the front surfaces of the three vertical rods 1 are provided with a plurality of groups of clamping components 3, the number of the clamping components 3 is the same as that of the protection components 2, each group of clamping components 3 comprises three clamping parts 31, each clamping part 31 comprises a vertical plate 311 and an L-shaped limiting plate 312, the vertical plate 311 is fixed on the front surface of each vertical rod 1, the L-shaped limiting plate 312 is vertically connected with the bottom of the vertical plate 311, the tail end of the L-shaped limiting plate 312 tilts outwards, the inner side of the L-shaped limiting plate 312 is provided with a protruding part 313, the left end, the middle part and the right end of the second cross rod 22 are provided with concave parts 221 which are matched with the convex parts 313, and the second cross rod 22 is erected on the three clamping pieces 31 of the three vertical rods 1. When the second cross rod 22 is clamped in the vertical plate, the protrusion of the L-shaped limiting plate 312 can clamp the second cross rod 22, so that the second cross rod 22 is not easy to move on the clamping piece 31, and the safety is improved. When the inner side of the adjacent edge hole needs to be operated, the second cross rod 22 is detached, and then a constructor can drill into the adjacent edge hole for operation through the distance between the first cross rod and the third cross rod.

In the present invention, one end of the angle iron 11 is welded to the vertical rod 1, and the other end of the angle iron is fixed to the scissor wall (not shown) by an expansion screw (not shown). So that the guard rail can be mounted or dismounted from the scissor wall.

The first cross bar 21 and the third cross bar 23 are transversely welded or fixed on the three vertical bars 1 through bolts. So that the guard rail can be more firm.
