Abstract
The invention discloses a kind of lightgage steel joist, it comprises bottom panel and two side panels that are parallel to each other, described bottom panel is by being longitudinally divided into two bottom panel halfbodies, the relative side of described two bottom panel halfbodies is vertical with two side panels respectively to be fixed, the adjacent side of described two bottom panel halfbodies is respectively equipped with vertical flanging, be provided with bridge insulation thermal resistance bar between the flanging of described two bottom panel halfbodies, fix bayonet connection outside the flanging of described two bottom panel halfbodies and be provided with U-shaped heat insulating strip between the flanging of described two bottom panel halfbodies and bayonet connection.Such scheme, improves the sound insulation of lightgage steel joist, heat-proof quality, can meet and use sound insulation and the higher place of insulation requirement.Adopt buckle to connect simultaneously and strengthen keel structure intensity, reduce difficulty of construction, meet the requirement of integrated production.Therefore, lightgage steel joist of the present invention can simplify body of wall make construction, reduce body of wall take up room, reduce engineering cost.
Description
Technical field
The present invention relates to a kind of lightgage steel joist, particularly relate to a kind of lightgage steel joist with high sound insulation, heat-proof quality, belong to building decoration technology field.
Background technology
The partition wall of interior decoration, often adopts lightgage steel joist as the skeleton of body of wall, the fixing decorative panel in outside in then on the skeleton of lightgage steel joist.The structure of lightgage steel joist is generally flute profile, namely a bottom panel and two side panels that are parallel to each other are comprised, the side of two side panels is fixed with bottom panel two side respectively, because the metal material making lightgage steel joist has good leading note and heat-conductive characteristic, therefore, there is the shortcoming that sound insulation value is low, effect of heat insulation is poor in the body of wall made of existing lightgage steel joist.Therefore to sound insulation and the higher place such as agglomeration, arenas, studio of insulation requirement, light steel keel partition usually adopts body of wall to thicken, increases the panel number of plies or adopts two-layer wall to form the deficiencies such as the ways such as sound insulation cavity solve sound insulation and heat conducting problem, and the construction causing body of wall to make is complicated, body of wall takes up room greatly, engineering cost is large.
Summary of the invention
For above-mentioned situation, the problem that quasi-solution of the present invention is determined is to provide a kind of sound insulation, well-insulated lightgage steel joist, meet agglomeration, arenas, studio etc. to use sound insulation and the higher place of insulation requirement, simplifying construction that body of wall makes, reduce body of wall and take up room, reduce engineering cost.
For reaching above-mentioned purpose, the present invention is by the following technical solutions: a kind of lightgage steel joist, it comprises bottom panel and two side panels that are parallel to each other, described bottom panel is by being longitudinally divided into two bottom panel halfbodies, the relative side of described two bottom panel halfbodies is vertical with two side panels respectively to be fixed, the adjacent side of described two bottom panel halfbodies is respectively equipped with vertical flanging, bridge insulation thermal resistance bar is provided with between the flanging of described two bottom panel halfbodies, bayonet connection is fixed outside the flanging of described two bottom panel halfbodies, and be provided with U-shaped heat insulating strip between the flanging of described two bottom panel halfbodies and bayonet connection.
Described bayonet connection comprises a capping and two sides, and described two sides are provided with longitudinal card indent.
The end of described two side panels also can be provided with the facing fillet of bending, facilitates the fixing of decoration panel and light steel keel support like this.
Adopt such scheme, lightgage steel joist of the present invention, bottom panel is by being longitudinally divided into two bottom panel halfbodies, the adjacent side of two bottom panel halfbodies is respectively equipped with vertical flanging, then by bayonet connection, two bottom panel halfbodies are connected again, due in two bottom panel half attachment structures, bridge insulation thermal resistance bar is provided with between the flanging of two bottom panel halfbodies, U-shaped heat insulating strip is provided with between the flanging of two bottom panel halfbodies and bayonet connection, the arranging of such bridge insulation thermal resistance bar and U-shaped heat insulating strip has blocked metal acoustic between two bottom panel halfbodies and metal heat-conducting, namely according to " bridge cut-off principle ", improve the sound insulation of lightgage steel joist, heat-proof quality, agglomeration can be met, arenas, studios etc. use sound insulation and the higher place of insulation requirement.Adopt buckle to connect simultaneously and strengthen keel structure intensity, reduce difficulty of construction, meet the requirement of integrated production.Therefore, lightgage steel joist of the present invention can simplify body of wall make construction, reduce body of wall take up room, reduce engineering cost.

Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3, Figure 4, lightgage steel joist of the present invention, its shape is U-shaped, namely comprises bottom panel 2 and two side panels 1 that are parallel to each other.The bottom panel 2 of existing lightgage steel joist is an overall structure, but the bottom panel 2 of lightgage steel joist of the present invention is by being longitudinally divided into two bottom panel halfbodies, the relative side of described two bottom panel halfbodies is vertical with two side panels 1 respectively to be fixed, the adjacent side of described two bottom panel halfbodies is respectively equipped with vertical flanging 3, the overbending direction of described flanging 3 and the same direction of side panel 1, and the width of flanging 3 is less than the width of side panel 1.
The flanging 3 of described two bottom panel halfbodies near and be provided with bridge insulation thermal resistance bar 4 between the flanging 3 of described two bottom panel halfbodies, described bridge insulation thermal resistance bar 4 is rectangular slat shape, and it can be made up of heat-barrier materials such as nylon.
Fix bayonet connection 5 outside the flanging 3 of described two bottom panel halfbodies and be provided with U-shaped heat insulating strip 6 between the flanging 3 of described two bottom panel halfbodies and bayonet connection 5.Described U-shaped heat insulating strip 6 also can be made up of heat-barrier materials such as nylon.Described bayonet connection 5 comprises a capping and two sides, and described two sides are provided with longitudinal card indent 7.Described bayonet connection 5 covers the flanging 3 of two bottom panel halfbodies by three bread, and the flanging 3 of two bottom panel halfbodies, bridge insulation thermal resistance bar 4, U-shaped heat insulating strip 6 is fixed together by card indent 7, is connected by two bottom panel halfbodies.
As the improvement of lightgage steel joist, the facing fillet 8 of bending also also can be provided with in the end of described two side panels 1.By arranging connecting hole on facing fillet 8, facing can be facilitated to be connected to in light steel keel support.
