Abstract
The utility model discloses a light steel keel comprising a bottom board and two side boards parallel to each other. The bottom board is longitudinally split into two bottom board halves; opposing sides of the bottom board halves are perpendicularly fixed to the side boards respectively; adjacent sides of the bottom board halves are provided with perpendicular folded edges; a bridge cut-off thermal barrier is arranged between the folded edges of the bottom board halves; a fastening connector is fixed on the outer sides of the folded edges of the bottom board halves; a U-shaped thermal barrier is disposed between the folded edges of the bottom board halves and the fastening connector. According to the scheme, sound insulation and thermal insulation are improved for the light steel keel, and the light steel keel is applicable to the places having high requirements on sound insulation and thermal insulation. Meanwhile, fastening connection is adopted to enhance structural strength of the light steel keel, construction difficulty is lowered, and the requirement for integrated production is met. Therefore, the light steel keel has the advantages that manufacturing of a wall can be simplified, space for the wall can be reduced and engineering cost can be lowered.
Description
Technical field
The utility model relates to a kind of lightgage steel joist, relates in particular to a kind of lightgage steel joist with high sound insulation, heat-proof quality, belongs 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, then the fixing decorative panel in the interior outside on the skeleton of lightgage steel joist.The structure of lightgage steel joist is generally flute profile, comprise a bottom panel and two side panels that are parallel to each other, one side of two side panels is fixed with bottom panel two sides respectively, owing to making the metal material of lightgage steel joist, there is good leading note and heat-conductive characteristic,, there is the shortcoming that sound insulation value is low, effect of heat insulation is poor in the body of wall that therefore existing lightgage steel joist is made.Therefore to places such as sound insulation and heat insulation agglomeration of having relatively high expectations, arenas, studios, light steel keel partition conventionally adopts body of wall thickening, increases the panel number of plies or adopts double-deck body of wall to form the ways such as sound insulation cavity and solves sound insulation and heat conducting problem, causes the deficiencies such as construction complexity, body of wall that body of wall is made take up room greatly, engineering cost is large.
Utility model content
For above-mentioned situation, the problem that the utility model quasi-solution is determined is to provide a kind of sound insulation, well-insulated lightgage steel joist, meet agglomeration, arenas, studio etc. sound insulation and heat insulation place of having relatively high expectations are used, simplifying construction that body of wall makes, reduce body of wall and take up room, reduce engineering cost.
For reaching above-mentioned purpose, the utility model 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, a relative side of described two bottom panel halfbodies is vertical fixing with two side panels respectively, an adjacent side of described two bottom panel halfbodies is respectively equipped with vertical flanging, between the flanging of described two bottom panel halfbodies, be provided with bridge insulation thermal resistance bar, the flanging outside of described two bottom panel halfbodies is bayonet connection fixedly, and between the flanging of described two bottom panel halfbodies and bayonet connection, be provided with U-shaped heat insulating strip.
Described bayonet connection comprises a capping and two sides, and described two sides are provided with blocks indent longitudinally.
The end of described two side panels also can be provided with the facing fillet of bending, facilitates like this fixing of decoration panel and lightgage steel joist support.
Adopt such scheme, lightgage steel joist of the present utility model, bottom panel is by being longitudinally divided into two bottom panel halfbodies, an 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, between the flanging of two bottom panel halfbodies, be provided with bridge insulation thermal resistance bar, between the flanging of two bottom panel halfbodies and bayonet connection, be provided with U-shaped heat insulating strip, bridge insulation thermal resistance bar and U-shaped heat insulating strip arranges metal acoustic and the metal heat-conducting of having blocked between two bottom panel halfbodies like this, according to " bridge cut-off principle ", improved the sound insulation of lightgage steel joist, heat-proof quality, can meet agglomeration, arenas, studios etc. are used sound insulation and heat insulation place of having relatively high expectations.Adopt buckle to connect to strengthen keel structure intensity simultaneously, reduced difficulty of construction, met the requirement of integrated production.Therefore, lightgage steel joist of the present utility model can be simplified construction that body of wall makes, reduce body of wall and take up room, reduce engineering cost.

The specific embodiment
As shown in Figure 1, Figure 2, Figure 3, Figure 4, lightgage steel joist of the present utility model, it is shaped as U-shaped, 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 of lightgage steel joist of the present utility model 2 is by being longitudinally divided into two bottom panel halfbodies, a relative side of described two bottom panel halfbodies is vertical fixing with two side panels 1 respectively, an 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 the flanging 3 of described two bottom panel halfbodies between be provided with bridge insulation thermal resistance bar 4, described bridge insulation thermal resistance bar 4 is rectangle strip, it can be made by heat-barrier materials such as nylon.
Flanging 3 outsides of described two bottom panel halfbodies are fixedly provided with U-shaped heat insulating strip 6 between the flanging 3 of bayonet connection 5 and described two bottom panel halfbodies and bayonet connection 5.Described U-shaped heat insulating strip 6 also can be made by heat-barrier materials such as nylon.Described bayonet connection 5 comprises a capping and two sides, and described two sides are provided with blocks indent 7 longitudinally.Described bayonet connection 5 covers the flanging 3 of two bottom panel halfbodies by three bread, and by card indent 7, the flanging of two bottom panel halfbodies 3, bridge insulation thermal resistance bar 4, U-shaped heat insulating strip 6 is fixed together, and two bottom panel halfbodies are connected.
As the improvement of lightgage steel joist, also can also be provided with in the end of described two side panels 1 the facing fillet 8 of bending.By connecting hole being set on facing fillet 8, can facilitate facing be connected to lightgage steel joist support on.
