Abstract
The utility model provides a lightweight steel keel with pits, which comprises a base plate and vertical edges, wherein the vertical edges are connected with the two sides of the base plate; the lightweight steel keel is characterized in that the pits are arranged on the outer surfaces of the base plate and the vertical edges; the pits are arrayed in rows; the quantity of the rows is two or more; the pits in the adjacent rows are arrayed in a staggered form and are consistent in bumping directions; and the pits are of hexagonal shape. The pits are arranged on the outer surfaces of the base plate and the vertical edges, so that the bearing capacity of the keel is enhanced and the shock resistance is increased; due to the design of the pits, an excellent anti-skidding property of the keel is supplied and the appearance is beautiful; and the lightweight steel keel with the pits has a simple structure, is low in cost and is suitable for wide application.
Description
Technical field
The utility model relates to the Building Decoration Material technical field, relates in particular to a kind of lightgage steel joist.
Background technology
Lightgage steel joist is that continuously dip coat zine plate take high-quality is as raw material, through the rolling metallic framework for building that forms of cold bending process.Being used for doing the non-bearing wall body of facing and the molding decorative of building roof with light weight boards such as Thistle board, decorated gypsum boards, is the basic material of multiple building roof, external and internal wall and shed frame type furred ceiling.But this keel are generally thinner, even be with strengthening groove or reinforcing rib, in use still can be out of shape because of unbalance stress.
Patent CN201343788Y provides a kind of light-gauge steel keel fixing element, comprises the fixture body, is arranged on the projection of fixture body surface, and the edge of described convex body forms reinforcing rib after 90 degree bendings, and the protruding back side arranges groove.Although this patent can improve stationarity and stability between the keel, structure is complicated, and cost is higher.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of lightgage steel joist with pit, comprises base plate and vertical edge, and described vertical edge is connected to the base plate both sides, it is characterized in that also being provided with pit on base plate and vertical edge external surface, and described pit is in a row arranged.
The quantity of described pit is more than 2 or 2.
The pit of described adjacent lines is staggered.
The concave and convex direction of described pit is consistent.
Described pit is shaped as hexagon.
The beneficial effects of the utility model are: at base plate and vertical edge external surface pit is set, can strengthens the supporting capacity of keel, improved shock resistance, and the design of pit can provide keel good non-skid property, and good looking appearance.The utility model is simple in structure, and cost is low, is suitable for extensive popularization.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further explained explanation.As shown in Figure 1,1-bottom, 2-vertical edge, 3-pit.
Above the specific embodiment of the present utility model is had been described in detail, but described content only is better embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
