Abstract
The utility model discloses a connection structure of a light gage steel joist, which comprises a bearing steel joist, a tapped steel joist and a connection part, wherein the connection part adopts integrated metal wires and is provided with two clamping pins which are respectively matched with clamping grooves at two side of the tapped steel joist, a connecting rod is respectively arranged above the two clamping pins of the connection part, the top ends of the connecting rods are connected together, and the top ends of the connecting rods are matched with the top surface of the bearing steel joist. The utility model has the advantages that the connection part adopts the integrated elastic metal wires, thereby having simple structure and greatly lowering the manufacturing cost of the connection part, meanwhile, the structures of the clamping pins and the connecting rods guarantee the strength of the connection part, thereby being more convenient and rapid on installation, the utility model does not need additional accessories, and the installation can be manually finished without tools, so the labor cost is reduced.
Description
Technical field
The utility model relates to a kind of lightgage steel joist, particularly discloses a kind of lightgage steel joist syndeton.
Background technology
At present, the connector of the lightgage steel joist on the market is generally tenon riveting structure or plate construction, need use auxiliary accessories such as screw, nut, rivet during connection, so just caused inconvenience has been installed, time-consuming taking a lot of work, because the restriction of tenon riveting, plate construction makes cost of production raising, production technology become complicated, on material and manpower, all need pay in a large number simultaneously.
Summary of the invention
The purpose of this utility model is to overcome defective of the prior art, provide a kind of simple in structure, with low cost, produce and install all lightgage steel joist syndeton easily and efficiently.
The utility model is achieved in that a kind of lightgage steel joist syndeton, comprise carrying keel, clad can keel, connector, it is characterized in that: described connector is the metal wire rod of one, described connector is provided with two card bases that match with the draw-in groove on clad can keel both sides respectively, the top of two card bases of described connector is provided with connecting rod respectively separately, the top of described connecting rod links to each other, and matches with the end face of described carrying keel in the top of described connecting rod.
The metal wire rod of described one is the rubber-like steel wire.
Described connecting rod lays respectively at the both sides of carrying keel, and is close proximity to the both sides of carrying keel.
Two card bases of described connector are symmetrical.
Distance between the distance between two card bases of described connector and the draw-in groove on clad can keel both sides is complementary.
Described connecting rod be shaped as linear pattern, bias type or shaped form.
The connecting rod of described two card bases top is symmetrical.
The beneficial effects of the utility model are: connector adopts the elastic metallic wire rod of one, simple in structure, make the cost of production of connector reduce greatly, the structure of card base and connecting rod has guaranteed the intensity of connector simultaneously, and install convenient, quick, need not to add in addition accessory, tool free is manual during installation just can finish, and has reduced human cost.

The specific embodiment
According to Fig. 1～4, the utility model lightgage steel joist syndeton, comprise carrying keel 4, clad can keel 5, connector, described connector is by card base 1, connecting rod 2, connecting rod top 3 is formed, described connector is the rubber-like steel wire, described connector is provided with two card bases 1 that match with the draw-in groove 6 on clad can keel 5 both sides respectively, the top of two card bases 1 of described connector is provided with connecting rod 2 respectively separately, the top of described connecting rod links to each other, match with the end face of described carrying keel 4 in described connecting rod top 3. described connecting rod 2 lays respectively at the both sides of carrying keel 4, and is close proximity to the both sides of carrying keel 4. two card bases 1 of described connector are symmetrical. the distance between the distance between two card bases 1 of described connector and the draw-in groove 6 on clad can keel 5 both sides is complementary. described connecting rod 2 be shaped as linear pattern, bias type or shaped form. the connecting rod 2 of described two card base 1 tops is symmetrical.
During use, connector is enclosed within on the carrying keel 4, makes connecting rod top 3 contact carrying keel, 4 end faces, this moment, two connecting rods of connector abutted against the both sides of carrying keel 4.Push connecting rod 2 then, thereby making the distance between two connecting rod 2 lower ends shorten the distance shortening that drives between two card bases 1 under the elastic reaction of steel wire, until the draw-in groove 6 of card base 1 being put into clad can keel 5, discharge connecting rod 2 at last, finish the connection of carrying keel 4 and clad can keel 5.
Claims (6)
