Abstract
The utility model discloses a welding-free fence. The welding-free fence comprises transverse bars in the shape of a square tube, wherein a rectangular vertical bar installation hole is formed in each of the upper surface and the lower surface of each transverse bar; the edge opening of each installation hole is connected with downward folded edges; the interval between every two opposite folded edges is the same as the vertical bars in size. Since the edge opening of each installation hole is provided with the downward folded edges, surface contact between each transverse bar and the corresponding vertical bar can be formed, the coating on the surface of each vertical bar is unlikely to be worn, the installation holes can be matched with the vertical bars in area, the fence does not loosen in use and the service life of the fence is prolonged.
Description
Technical field
The utility model relates to fence field, is specifically related to a kind of fence of exempting to weld.
Background technology
Exempting to weld fence is a kind of fence being assemblied to form by cross bar and montant, cross bar is provided with installing hole, the position dilatancy that montant runs through cross bar and makes montant be positioned at cross bar inner chamber by instrument realizes spacing up and down, and pour into a mould into cement wall surface cross bar two ends and montant lower end; Cross bar and montant are all the zinc-plated box sections of inside and outside wall difference, the outer wall of cross bar and montant also respectively electrostatic scribble coating, installing hole on cross bar is processed by punch press, its limit portion section is neat, in assembled process, for preventing that coating is mounted the wearing and tearing of limit, hole portion, the size of installing hole will be a bit larger tham the cross section of montant, then the plastics waterproofing pad by π shape compresses, plastics waterproofing pad is at outdoor easy aged deterioration, between montant and cross bar, the loosening intensity that affects fence integral body, makes fence lose the effect of protection, and the application life of fence is short.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of fence of exempting to weld, can solve the existing montant installing hole size of exempting to weld fence and be greater than montant cross section to avoid the coating that weares and teares, need to adopt plastics waterproofing pad to compress, the easy aged deterioration of plastics waterproofing pad, causes fence short problem in application life.
The utility model is achieved through the following technical solutions:
Exempt to weld a fence, comprise square-tube-shaped cross bar, described cross bar upper and lower faces is respectively equipped with the montant installing hole of rectangle, and the limit mouth of described installing hole is connected with respectively the flanging of downward turnover, and the spacing between relative flanging equates with the size of montant.
The joint face of described flanging and installing hole limit portion is the cambered surface of radius 0.5 ~ 1mm.
The utility model advantage is compared with prior art:
The limit mouth of installing hole is provided with flanging, and formation face between cross bar and montant is contacted, and the coating on the montant surface that is not easy to wear and tear, can match with montant the area of installing hole, there will not be looseningly in fence use procedure, extends application life of fence.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1 a kind of exempts to weld fence, comprise square-tube-shaped cross bar 1, on described cross bar 1, lower two sides is respectively equipped with the montant installing hole 2 of rectangle, it is first on cross bar when installing hole 2 is set, offer cross crotch below, then with mould, from cross crotch, press down, form the installing hole 2 that limit mouth is connected with respectively the flanging 3 of downward turnover, according to the length of montant adjusted size cross crotch, spacing between relative flanging 3 is equated with the size of montant, the joint face of described flanging 3 and installing hole 2 limit portions is set to the cambered surface of radius 0.5 ~ 1mm, can better prevent that the coating of montant is worn.
Claims (2)
1. exempt to weld fence for one kind, comprise square-tube-shaped cross bar (1), described cross bar (1) upper and lower faces is respectively equipped with the montant installing hole (2) of rectangle, it is characterized in that: the limit mouth of described installing hole (2) is connected with respectively the flanging (3) of downward turnover, and the spacing between relative flanging (3) equates with the size of montant.
2. a kind of fence of exempting to weld as claimed in claim 1, is characterized in that: described flanging (3) is the cambered surface of radius 0.5 ~ 1mm with the joint face of installing hole (2) limit portion.
