Abstract
Disclosed is an expansion joint light steel joist which comprises a groove-shaped joint body and a connector integral with the groove-shaped joint body, wherein the connector disposed at one end of the groove-shaped joint body has a relatively reduced dimension, two lateral walls at the other end of the joist body are respectively provided with at least one elastic stop stripped channel and one elastic ejection stripped channel in longitudinal direction and horizontal direction, and the two lateral walls of the connector are respectively provided with at least one elastic expanded-joint snapping strip in longitudinal direction and horizontal direction. The expansion joint light steel joist is convenient for detachment, timesaving and laborsaving, and increases work efficiency.
Description
Technical field
The utility model relates to building, ornamental lightgage steel joist, particularly a kind of expanded joint formula lightgage steel joist.
Background technology
Lightgage steel joist is widely used in building, decoration industry.But being connected between keel and the keel realizes by connector mostly that at present the clad can keel are no exception, and operating efficiency is just very low like this.Occurred a kind of clad can keel with connector on the market, this clad can keel adopt disposable punching press, an opening.In work progress, need right this clad can keel to improve certain operating efficiency, but its shortcoming is exactly: relatively more painstaking, connection tension when not having shrinkage, two keel connections, withdraw from as needs, must be by instrument.Loading, unloading are extremely inconvenient, influenced operating efficiency.
Summary of the invention
The purpose of this utility model is in order to overcome the prior art above shortcomings, provide a kind of easy to loading and unloading, save time, the laborsaving and expanded joint formula lightgage steel joist of increasing work efficiency.
The utility model is achieved through the following technical solutions, a kind of expanded joint formula lightgage steel joist, comprise that it is one and the relative joint that dwindles of size that is arranged on the one end that the trough keel body reaches with it, it is characterized in that: the two side of the other end of described keel body respectively has vertically, laterally at least one elasticity stop bit, the bar groove of giving up the throne, and respectively has vertically in the two side of joint, horizontal at least one elasticity expanded joint card article.
The utility model is owing to the advantage that has adopted said structure to have is: easy to loading and unloading, save time and laborsaving, improved operating efficiency.
Description of drawings
The utility model said structure can further specify by the non-limiting embodiment that accompanying drawing provides.
Fig. 1 is a structural representation of the present utility model;
Structural representation when Fig. 1 works for the utility model.
Among the figure: 1, trough keel body; 2, joint; 3, elasticity expanded joint bar; 4, elasticity stop bit, the bar of giving up the throne.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Referring to accompanying drawing, it is one and the relative joint that dwindles 2 of size that is arranged on the one end that trough keel body 1 among the figure reaches with it, wherein: the two side of the other end of described keel body respectively has vertically, laterally at least one elasticity stop bit, the bar groove 4 of giving up the throne, and respectively has vertically in the two side of joint, horizontal at least one elasticity expanded joint card article 3.
In the said structure, described spring expanded joint card article 3 is three openings one side and the sidewall of trough keel body 1 connects as one, and the size of elasticity stop bit, the bar groove 4 of giving up the throne is not less than elasticity expanded joint card article 3.
Operating principle of the present utility model: an end that keel is had joint inserts another root keel band elasticity stop bit, bar groove 4 these ends of giving up the throne, and has just realized being connected between keel and the keel; As fortuitous event, need unload lower keel, just with a hand pin the elasticity stop bit, the bar groove 4 of giving up the throne, keel are dragged outward in the side with the another hand again, this just can unload lower keel.
In sum, tool free is unloaded in the utility model loading, unloading very easily, because very laborsaving, that has just improved operating efficiency in cargo handling process.
Claims (3)
1, a kind of expanded joint formula lightgage steel joist, comprise that it is one and the relative joint that dwindles of size (2) that is arranged on the one end that trough keel body (1) reaches with it, it is characterized in that: the two side of the other end of described keel body respectively has vertically, laterally at least one elasticity stop bit, the bar groove (4) of giving up the throne, and respectively has vertically in the two side of joint (2), horizontal at least one elasticity expanded joint card article (3).
2, expanded joint formula lightgage steel joist according to claim 1 is characterized in that: described spring expanded joint card article (3) is three openings one side and the sidewall of trough keel body (1) connects as one.
