Abstract
The utility model provides a high-strength guardrail inserting piece. The high-strength guardrail inserting piece comprises a cylinder and a bottom cover, wherein the bottom cover is arranged at one end of the cylinder, and the combination part of the bottom cover and the cylinder is in smooth transition, so that the high-strength guardrail inserting piece is shaped like an opened cubic box and is made of steel plates. According to the high-strength guardrail inserting piece, the combination part of the cylinder and the bottom cover is smooth without edges and corners, the high-strength good steel plates are adopted as materials, the high-strength guardrail inserting piece is formed by cold drawing of a mechanical mold, so that the strength of a workpiece is further strengthened on the basis of the conventional steel plate.
Description
Technical field
The utility model relates to a kind of high strength guardrail for building the connection plug connector is installed.
Background technology
The guardrail connector is a kind of being used to build the connector that connection is installed in guardrail batch production manufacturing, and it can connect the vertical and horizontal steel pipe, and it is safe in utilization and stable to be directly connected to whole guardrail application life.Present guardrail connector is conventional aluminium matter guardrail connector, and is as depicted in figs. 1 and 2, and it comprises cylindrical shell 1 and bottom 2.Because aluminium matter mechanical strength is low, is generally δ b 60-100MPa, again because of the limitation of die-casting process technology, make product material interior tissue density loose, congenital intensity difference, being embodied in shock resistance can be poor, and the surface is easy to crack; Resistance to corrosion is poor, in natural wet environment or under the sun, is exposed to the sun for a long time, and 2-3 will be rotten disorderly damaged after the year.Its congenital performance has determined that aluminium matter guardrail connector is shorter application life, has also caused the not high problem of safety.
For strengthening the mechanical strength of aluminium matter guardrail connector, strengthen mechanical performance and improve application life if increase wall thickness, product material consumption and manufacturing cost will be increased, it is clumsy that product appearance also shows.
Summary of the invention
The purpose of the utility model is to provide a kind of high strength guardrail plug connector, is used to solve the problem that intensity is low, application life is short that existing aluminium matter guardrail connector exists.
In order to address the above problem; The high strength guardrail connector that the utility model provides comprises cylindrical shell and bottom; Said bottom is located at an end of said cylindrical shell; And the junction smooth transition of said bottom and said cylindrical shell makes opening-like cube of box-like of said high strength guardrail connector, and the material of said high strength guardrail connector is the steel plate of cold stretch.
Level and smooth unstressed the concentrating in cylindrical shell of the utility model and bottom junction, and the utility model makes material through selecting the higher quality steel plate of intensity for use, processes through the machine die cold stretch, and intensity is further strengthened on the basis of former steel plate.
Description of drawings
Fig. 1 is the perspective view of existing aluminium matter guardrail connector;
Fig. 2 is the cross-sectional view of existing aluminium matter guardrail connector;
Fig. 3 is the perspective view of the utility model;
Fig. 4 is the cross-sectional view of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is explained further details.
Fig. 3 and Fig. 4 schematically show the structure of the utility model, and be as shown in the figure, and it comprises cylindrical shell 10 and bottom 20; The length of cylindrical shell 10 equates; Bottom 20 is located at an end of cylindrical shell 10, and junction 12 smooth transition of bottom 20 and cylindrical shell 10, feasible this opening-like cube of box-like; In addition, this material is the steel plate of cold stretch.In other embodiments, different according to concrete application, the length and width height of cylindrical shell 10 also can be unequal.
The utility model has proposed a kind of new design for improving whole safety in utilization of guardrail and stability.It is shaped as opening shape cube box-like, processes through the cold stretch processes with quality steel plate.Because quality steel plate mechanical strength higher (δ b370-420Mp) produces the work hardening process when cold stretch processes is made, the metal inside mechanical strength is further improved, thereby obtain high-intensity guardrail connector product.Compare with existing conventional aluminium matter guardrail connector, the mechanical strength of the utility model is high about 4 times, use same surface treatment method after, prolong application life at double.Whereby, the product strength of the utility model improves, and safety and reliability improve; The product design wall thickness reduction, volume reduces, and material consumption reduces, and outward appearance is merrily and lightheartedly attractive in appearance, and production efficiency is high in addition, has reduced product cost and price; To the environment for use wide adaptability, be not afraid of humidity, do not receive the high low temperature effect of nature, the antioxidant anticorrosive performance strengthens.Do not exist cracking to be decreased, safe and reliable, be specially adapted to highrise building guard bar structure connector.
Can know that by technological general knowledge the utility model can be realized through other the embodiment that does not break away from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all just illustrates, and is not only.All in the utility model scope or the change that is being equal in the scope of the utility model all comprised by the utility model.
