Abstract
The utility model discloses a protective barrier capable of freely stretching and retracting. The protective barrier comprises a handrail set and a concrete masonry. The handrail set comprises a steel pipe, threaded rods, round seal-capping steel plates and hexagon nuts, the number of the round seal-capping steel plates is two, the round seal-capping steel plates are welded to the two ends of the steel pipe respectively, the hexagon nuts are installed on each round seal-capping steel plate, the number of the threaded rods is two, one end of each threaded rod penetrates through one seal-capping steel plate to penetrate into the steel pipe, and one hexagon nut is fixed at the other end of each threaded rod and abuts against the concrete masonry. The protective barrier capable of freely stretching and retracting is simple in structure, safe and reliable, adopts a screw connection mode which can achieve disassembly conveniently, can adjust the length of a handrail conveniently and timely within a certain length range, saves steel pipes compared with the prior art, and is convenient to use and practical. In addition, the protective barrier capable of freely stretching and retracting is convenient to disassemble and assemble, can be repeatedly used to reduce engineering cost, and causes no damage to the concrete masonry.
Description
Technical field
The utility model relates to the construction work safety device, is specifically related to a kind of guard rail of free-extension.
Background technology
In carrying out the building structure construction, it is particularly important that security protection seems.Especially to facing the protection at hole, limit.Generally, facing that frontier defense protects is all generally to set up with steel pipe, set up process need and expend a large amount of human and material resources, take, tear open process loaded down with trivial details, and set up the material that different railings needs different length, sometimes after construction operation finishes and to recover between protection formation time poor, stay that to face the blank time section that frontier defense protects be also great potential safety hazard.
The utility model summary of the invention
Goal of the invention: the utility model provides a kind of simple in structure, safe and reliable, the guard rail of the retractable of convenient disassembly for the problems of the prior art.
Technical scheme: for solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of guard rail of free-extension, comprise railing group and concrete masonry, and described railing group comprises steel pipe, screw rod, the circular steel plate of capping and hexagonal (hexagon)nut; The circular steel plate of described capping is provided with 2, be welded on respectively the two ends of steel pipe, described hexagonal (hexagon)nut is arranged on the circular steel plate of each capping, described screw rod is provided with 2, one end of each root screw rod passes respectively the inside that the circular steel plate of capping is deep into steel pipe, is fixed with hexagonal (hexagon)nut on the other end and withstands on concrete masonry.
The utility model adopts the combination of steel pipe, screw rod and other parts, consists of an assembling, convenient disassembly, the guard rail of retractable.The utility model can be within necessarily facing hem width degree scope free adjustment length, and repeatedly disassembly and assembly are reused.
As preferably, the end that screw rod withstands concrete masonry also is provided with circular shim, and described circular shim withstands on concrete masonry; Circular shim can enlarge the contact area of screw rod and concrete masonry, has increased stability.
As preferably, also be provided with rubber buffer between described circular shim and concrete masonry; Rubber buffer can play cushioning effect, can not destroy concrete masonry, and can increase the frictional force between screw rod and concrete masonry, prevents coming off between the two.
As preferably, described railing group is provided with 2 groups; 2 groups of railing groups are assembled into whole guard rail, have reduced potential safety hazard.
Beneficial effect: compared with prior art, the utlity model has following advantage: the utility model is simple in structure, safe and reliable, adopt the screw rod connected mode of easy disassembly, the length of real-time adjustment railing easily, simultaneously also can adjust length in certain length range, compare conventional method and save light pipe, convenient and practical; And the utility model easy accessibility can be reused the reduction engineering cost, and concrete masonry is not caused any destruction.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
With reference to Fig. 1, a kind of guard rail of free-extension comprises railing group and concrete masonry 1, and the railing group comprises steel pipe 2, screw rod 3, the circular steel plate 4 of capping and hexagonal (hexagon)nut 5; The circular steel plate 4 of capping is provided with 2, be welded on respectively the two ends of steel pipe 2, hexagonal (hexagon)nut 5 is arranged on the circular steel plate 4 of each capping, screw rod 3 is provided with 2, one end of each root screw rod 3 passes respectively the inside that the circular steel plate 4 of capping is deep into steel pipe 2, is fixed with hexagonal (hexagon)nut 5 on the other end and withstands on concrete masonry 1; The end that screw rod 3 withstands concrete masonry 1 also is provided with circular shim 6, and circular shim 6 withstands on concrete masonry 1; Also be provided with rubber buffer 7 between circular shim 6 and concrete masonry 1; The railing group is provided with 2 groups.
The utility model in use, need to first fix a wherein end of a screw rod, hexagonal (hexagon)nut need to first be installed, then circular shim places the rubber cushion pad, and such end first withstands concrete masonry, then progressively extend other end screw rod, withstand concrete masonry, install equally hexagonal (hexagon)nut, circular shim; After the relative position of steel pipe and screw rod is determined substantially, by the hexagonal (hexagon)nut on the circular steel plate of fastening capping, the position of steel pipe and screw rod is fixed, must be fastened to maximum value, prevent from coming off.
The above is only better embodiment of the present utility model; protection domain of the present utility model is not limited with above-mentioned embodiment; in every case the equivalence done according to the utility model institute disclosure of those of ordinary skills is modified or changes, and all should include in the protection domain of putting down in writing in claims.
