Description
Technical field
The utility model relates to a kind of novel lightgage steel joist, particularly relates to one and has high sound insulation, heat-proof quality, can be suitable for the eccentric bridge cut-off lightgage steel joist of universal keel; These keel improve sound insulation, the heat-insulating capability of partition wall, have saved the consumption of steel, have decreased taking up room of indoor wall; Belong to building decoration technology field.
Background technology
Lightgage steel joist is a kind of good leading note and heat transfer constructional materials, therefore traditional lightgage steel joist Light Wall, due to directly transaudient, the characteristics of heat transfer of lightgage steel joist, there is the shortcoming that sound insulation value is low, effect of heat insulation is poor.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 ways such as sound insulation cavity and solves sound insulation and heat conducting problem.
There is certain defect in these methods: one is because body of wall widens the use amount adding steel, and body of wall takies the interior space and increases, and indoor usage space reduces; Two is increase because of the panel number of plies difficulty of construction increasing engineering, extends the construction period of engineering, artificial and material consumption increase; Three is because in two-layer wall, the structural strength of individual layer body of wall is more weak, cause body of wall stable not, and the construction of two-layer wall is more complicated, adds engineering cost, reduces the economic benefit that engineering uses.
Although existing bridge cut-off keel solve above-mentioned defect, itself also has some problems: one is that structural member own is many, changes trouble, causes assembled complexity, take time and effort; Two is structure problems, can not add general punching keel and gain in strength, cause needing special-shaped keel, also increase engineering cost, reduce economic benefit.
Utility model content
For above-mentioned situation, the utility model is intended providing one can meet high sound insulation and insulation requirement, can use the eccentric bridge cut-off lightgage steel joist of universal keel, these keel have install simple and easy quick, take up room little, structural strength is high, the feature such as good in economic efficiency.
For achieving the above object, the utility model have employed following technical scheme: a kind of novel bridge cutoff type lightgage steel joist, and it comprises the eccentric tread limit and eccentric keel minor face that are connected, and eccentric tread limit and eccentric keel minor face junction are provided with bridge insulation thermal resistance bar;
Described eccentric tread limit is L-type structure, comprises long side limit, base, long limit; Described long side limit is evenly equipped with ribs, and side top bends inwards; There is reinforcing rib on base on described long limit, and top, base has and upwards bends, and forms contained side, uniform trapezoid-shaped openings on base, described long limit.
Described bridge insulation thermal resistance bar is the heat insulating strip of U-shaped rectangular slat shape;
Described eccentric keel minor face is L-type, comprises minor face side, minor face base; Described minor face side is evenly equipped with ribs, and side top bends inwards; There is reinforcing rib on described minor face base, and top, base has and upwards bends, and described bending has oppositely second time bending in stage casing, be bent to form jaws described twice; Described eccentric type bridge cut-off lightgage steel joist, described bridge insulation thermal resistance bar is closely attached on the contained side on described eccentric tread limit, then the jaws of eccentric keel minor face is aimed at contained side, tightly clip from top to bottom, finally to be set level in described eccentric tread limit and eccentric keel minor face adjustment and combine, the bending angle of the corresponding bending place of the utility model is 90 degree.
The utility model is according to " bridge cut-off principle ", bridge insulation thermal resistance bar is adopted to separate the mode of lightgage steel joist, reduce lightgage steel joist directly transaudient, heat transfer performance, make the sound insulation of bridge cutoff type lightgage steel joist, heat-proof quality, the instructions for use in the places such as agglomeration, arenas, studio can be met, decrease the use amount of steel, increase indoor usage space; Decrease the practical, number of special-shaped keel, decrease difficulty of construction and cost; Adopt buckle to connect simultaneously and strengthen keel structure intensity, reduce difficulty of construction simultaneously, meet the requirement of integrated production.

In figure: the eccentric tread limit of 1-, the eccentric keel minor face of 2-, 3-bridge insulation thermal resistance bar, 4-long side limit, 5-long limit minor face, 6-contained side, 7-minor face side, 8-minor face base, 9-jaws, 10-ribs, 11-reinforcing rib.
Detailed description of the invention
Composition graphs 1, Fig. 2, Fig. 3, Fig. 4, the utility model have employed following technical scheme: a kind of novel eccentric bridge cut-off lightgage steel joist, it comprises eccentric tread limit 1, eccentric keel minor face 2, bridge insulation thermal resistance bar 3, described eccentric tread limit 1 is connected with eccentric keel minor face 2, bridge insulation thermal resistance bar 3 is positioned at eccentric tread limit 1 and eccentric keel minor face 2 junction, both is separated.
Described eccentric tread limit 1 is in L-type structure, and its bending angle is 90 degree, comprises interconnective long side limit 4 and long limit minor face 5; Described long side limit 4 is all interval with ribs 10, and side top, long side limit 4 bends inwards, and described bending angle is 90 degree; Described long limit minor face 5 is provided with reinforcing rib 11, and its top, base upwards bends, and described bending angle is 90 degree, forms contained side 6 after bending.
