Description

Fast assembly formula guardrail

Technical Field

The invention relates to a quick assembly type guardrail.

Background

At present, a guardrail is made of iron, aluminum, stainless steel and other materials by assembling and welding. The assembly welding guardrail is troublesome to process and high in cost, and smoke dust generated during assembly welding can cause environmental pollution and harm to the health of related personnel. In addition, the welding process causes the defects of pipe deformation, corrosion and the like, and the phenomenon of falling off of the paint coating on the surface is serious, so that the later maintenance cost is high, and the later processes such as paint repair and the like are required.

The assembly of current guardrail adopts the manual work to assemble mostly, has seted up a plurality of holes on the crossbeam promptly, puts two piece at least crossbeams parallel, makes the aperture on two crossbeams align, then the manual work is with every longeron cartridge in corresponding hole, and its low in labor efficiency is big to this kind of mode intensity of labour, and after the cartridge, uses the welding machine to weld the cartridge position. And finally, a spraying process is carried out, and gaps are easy to exist in the welding part, so that a Faraday shielding effect is inevitably generated in the electrostatic spraying, and protective paint is not attached to a partial area, so that the corrosion resistance of the whole guardrail is poor.

Disclosure of Invention

The invention provides a quick-assembly guardrail aiming at the problems, which can avoid welding and direct assembly, is stably installed, can avoid Faraday shielding effect in electrostatic spraying and has better corrosion resistance.

In order to solve the technical problem, the invention provides a fast assembly type guardrail with the following structure, which comprises a plurality of transverse beams arranged at intervals and transversely arranged and longitudinal beams arranged at intervals and vertically arranged, wherein the transverse beams are provided with a plurality of vertically through insertion holes which are arranged at intervals and vertically aligned, and the fast assembly type guardrail is structurally characterized in that: the longitudinal beam is inserted into the insertion holes to realize the insertion connection of the longitudinal beams and the cross beams, the cross beams are provided with insertion parts, the insertion holes are located on the insertion parts, the insertion parts are provided with limiting cavities protruding from the hole walls of the insertion holes to the periphery, and the longitudinal beam is inserted into the cavity walls, protruding into the limiting cavities, of the limiting cavities and abutting against the cavity walls of the limiting cavities to ensure the firm insertion of the cross beams and the longitudinal beams.

The limiting protrusion is an annular convex rib.

The limiting protrusion is a ring platform arranged on the longitudinal beam.

Crossbeam and longeron are all made by square pipe, process the through-hole that sets up relatively on the two relative pipe walls on the side pipe, the inner chamber of two relative through-holes and the side pipe that is located between two through-holes forms jointly the cartridge hole, spacing chamber is the inner chamber that is located the side pipe of cartridge hole both sides.

The limiting protrusions are protrusions which are formed by inserting the longitudinal beams on the cross beams and then ejecting the pipe walls of the square pipes outwards through jacking equipment.

Compared with the prior art, the structure has the following advantages: because the cartridge section at the crossbeam sets up spacing chamber and sets up spacing protruding on the section of the cartridge of longeron, spacing protruding stretch get into spacing chamber and spacing protruding support the chamber wall in spacing chamber in order to guarantee the firm grafting of crossbeam and longeron, therefore can avoid the welding directly to assemble, the installation is firm, it can be equipment after the spraying earlier, the Faraday shielding effect in avoiding electrostatic spraying that like this can be fine makes it have better corrosion resisting property.

In conclusion, the invention has the advantages of firm and firm installation, convenient and fast installation and good corrosion resistance.
