Abstract
The invention relates to a building material, in particular to a light steel keel and a construction wall body made of the same. The light steel keel comprises a skeleton, wherein a groove parallel to the length direction of the skeleton is formed in the skeleton, and a rubber strip is embedded into the groove. The construction wall body adopts the structure that a decorative board is posted on the two skeletons; one groove parallel to the length direction of the skeleton is formed in the skeleton, and one rubber strip is embedded into the groove. By adopting the technical scheme, the structures of both a current skeleton and a construction wall body are changed, an excellent damping and weakening effect is played in a sound wave conduction process, and the transmitting energy of the sound wave is greatly consumed; particularly, when being used as a separation wall body, compared with a separation wall body made of a common keel, the construction wall body provided by the invention has better sound proofing performance, shock resistance and compression resistance. Tests show that compared with the prior art, the effect of sound insulation in different audio regions can be obvious improved, which can reach more than 5db.
Description
Technical field
The present invention relates to a kind of constructional materials, especially relate to a kind of lightgage steel joist of building nonbearing wall and the construction wall made from this lightgage steel joist.
Background technology
The lightgage steel joist of prior art and the construction wall made with this lightgage steel joist the poor and/or shock resistance of soundproof effect, problem that compressive strength is low because of the reasons in structure ubiquity of lightgage steel joist skeleton, have affected the public's living quality and the construction quality of building.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of prior art defect that overcomes, and has the lightgage steel joist of good sound insulation damping performance and a construction wall made from this lightgage steel joist.The technical scheme that the present invention solves its technical problem employing is: a kind of lightgage steel joist, and it comprises skeleton, skeleton is provided with the groove parallel with the skeleton length direction; The cross section of groove is the indent that trapezoidal, trapezoidal base is in groove; The indent of groove is provided with containing chamfering; In groove, be provided with rubber strip; The cross section of rubber strip is circular.A kind of construction wall, paste decorative panel on its 2 skeletons, and skeleton is provided with the groove parallel with the skeleton length direction; The cross section of groove is the indent that trapezoidal, trapezoidal base is in groove; The indent of groove is provided with containing chamfering; In groove, be provided with rubber strip; The cross section of rubber strip is circular.The present invention is provided with a groove and places rubber strip to reach raising damping soundproof effect on skeleton, be equivalent to again be provided with a reinforcing rib to strengthen shock resistance, compressive property on skeleton, if there is no this root rubber strip as buffer medium, the damping soundproof effect will be had a greatly reduced quality.Decorative panel of the present invention can be selected cellular board, gypsum plank etc., but the moulding of skeleton integral die-cast.The present invention is owing to adopting technique scheme, changed the structure of skeleton and the construction wall of prior art, sound wave is played to good damping and weakening effect in conductive process, greatly consumed the transferring energy of sound wave, particularly the present invention compares as the compartment wall body of wall with the compartment wall body of wall that common keel are made, and has better sound insulation and shock resistance, compressive property.After tested, compared with prior art, its defening effect has raising (more than can reaching 5db) clearly in different audio frequency zones in the present invention.
The accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiments of the invention, the present invention is described in further detail:
Fig. 1 is the perspective view of lightgage steel joist of the present invention.
Fig. 2 is the cross-sectional structure schematic diagram of lightgage steel joist of the present invention.
Fig. 3 is the A section enlarged drawing of Fig. 2.
Fig. 4 is the cross-sectional structure schematic diagram of construction wall of the present invention.
The specific embodiment
With reference to Fig. 1～Fig. 4, on skeleton 1 of the present invention, available self-tapping screw 7 pastes decorative panel 2, and skeleton 1 is provided with the groove 3 parallel with skeleton 1 length direction, and the cross section of groove 3 is trapezoidal shape, recess 4 places of groove are provided with containing closing in 5, in groove 3, are provided with rubber strip 6.
Embodiment 1: with reference to Fig. 1, Fig. 2, Fig. 3, the present embodiment is provided with 1 groove parallel with the skeleton length direction on the skeleton of lightgage steel joist, because of the ad hoc structure of groove, therefore can improve shock resistance of the present invention, compressive strength.
Embodiment 2: with reference to Fig. 1, Fig. 2, Fig. 3, the present embodiment is on the basis of embodiment 1, be designed to the cross section of groove trapezoidal, at the trapezoidal two jiaos of places that go to the bottom, make respectively 2 chamferings, chamfering is in the indent of groove, in groove, is provided with rubber strip, the indent of groove be provided with containing closing in (chamfering) so that rubber strip not from trapezoidal groove, coming off, increase simultaneously the contact area of rubber strip and keel, to improve soundproof effect of the present invention and shock resistance, compressive strength.
Embodiment 3: with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the present embodiment is selected the lightgage steel joist skeleton of inlaying rubber strip in the trapezoidal groove of containing closing in, and on 2 lightgage steel joist skeletons, paste decorative panel as the nonbearing wall in building at least, make construction wall have better soundproof effect and shock resistance, compressive strength, also improved whole solidness and the stability of construction wall simultaneously.
