Description

High sound insulation and high sound absorption double-layer ceiling system

technical field

The invention relates to a ceiling system.

Background technique

Existing ceiling system all is to lap one deck criss-cross keel on the indoor roof, then installs the painted keel on the bottom of the keel, and finally laps the mineral wool sound-absorbing board on the lacquered keel.

This ceiling method makes the distance between the mineral wool sound-absorbing panel and the roof very large, thereby reducing the height of the indoor space.

In addition, the existing ceiling system also has problems such as poor sound insulation effect.

Contents of the invention

The technical problem to be solved by the present invention is to provide a double-layer ceiling system with high sound insulation and high sound absorption, which can not only effectively increase the height of the indoor space, but also has a good sound insulation effect.

In order to solve the above problems, the present invention provides a double-layer ceiling system with high sound insulation and high sound absorption, including:

building roof;

Cassette keel, fixed on the roof of the building;

The cladding keel is clamped and fixed on the snap-type keel;

Gypsum plasterboard, fixed on the cladding keel by fasteners;

The main keel of the painted keel, the main keel of the painted keel is more than 2, and the main keels of the painted keel are arranged side by side on a plane in parallel, and the main keel of the painted keel is hung on the gypsum board by hanging parts;

The mineral wool sound-absorbing board is buckled on the main keel of the painted keel.

Preferably, the hanger includes: a direct hanger and a full-tooth hanger, the direct hanger is buckled on the main keel of the painted keel, and the direct hanger is hung on the building roof.

Preferably, the direct hanger includes: a first clamping piece and a second clamping piece, a first groove for clamping the plane paint keel is formed on the first clamping piece, and a first groove is formed on the second clamping piece There is a second groove for clamping the plane paint keel adapted to the first groove; a suspension piece is also provided at one end of the first clip; the first clip and the second clip The sheets are snapped together with fasteners.

Preferably, a supporting protrusion is also provided on the first clip.

The invention installs the gypsum board through the card-type keel, and directly hangs the main keel of the paint keel on the gypsum board through the hanger, which not only greatly reduces the distance between the mineral wool sound-absorbing board and the roof, but also effectively improves The space inside the house has a good sound absorption effect through the double-layer structure of paper-faced gypsum board and mineral wool gypsum board.

Detailed ways

As shown in Figure 1, the high sound insulation and high sound absorption double-layer ceiling system of the present invention includes: a building roof 1, a snap-type keel 3, a cladding keel 4, a paper plasterboard 6, a painted keel main keel 7 and a mineral wool sound-absorbing board 8. The clip joist 3 is fixed on the roof 1 of the building, the cladding joist 4 is clamped and fixed on the clip joist 3, and the plasterboard 6 is fixed on the cladding joist 4 through the fastener 5, and the fastener 5 can use self-tapping screws . There are more than 2 main keels 7 of the painted keel, which are shown as 3 in Fig. 1, and the main keels 7 of the painted keel are arranged side by side in parallel on a plane, and the main keel of the painted keel is hung on the plasterboard 6 through the hanger 2, The mineral wool sound-absorbing board 8 is buckled on the main keel 7 of the baking varnish keel.

Through the above structure, a double-layer ceiling system with high sound insulation and high sound absorption structure is formed. After testing, the sound absorption coefficient reaches 0.6-0.8, which is much higher than the simple mineral wool sound-absorbing panel ceiling system.

In addition, the hanger 2 of the present invention consists of three parts, including the first clip (namely the main part 21 ), the second clip (ie the accessory 22 ) and the fasteners as shown in FIG. 2 . In the present invention, set screws 23 are used as the fasteners.

In the hanger main part 21 shown in Figure 2, one end of the main part 21 is provided with a suspension piece 214, which is used to hang on the plasterboard 6 by self-tapping screws or screws, so as to fix itself and its lower parts. ceiling system components. The main part 21 is provided with a first groove 215 for clamping the main keel 7 of the paint keel, and the accessory 22 is provided with a first groove 215 for clamping the main keel 7 of the paint keel adapted to the first groove 215. Two grooves 225. The first groove 215 of the main part 21 and the second groove 225 in the accessory 22 clamp the top ribs of the main keel 7 of the paint keel together, and its shape basically matches the top rib of the main keel 7 of the paint keel, and can be installed during installation. Clamp the top rib of the main keel of the painted keel properly, without causing the main keel 7 of the painted keel to deflect or swing in any direction.

In addition, as shown in FIG. 2, a supporting projection 213 is also provided on the main part 21. The supporting projection 213 is a round bean-shaped fulcrum, which can be supported on the accessory 22 to lift the main part 21 and the main part 2 of the hanging part 2. The attachment 22 can be parallel when in use, to improve stability and increase the moment arm, thereby improving the effect of the clamping force on the main keel 7 of the painted keel.

In addition, as shown in FIG. 2 , a threaded hole 212 is provided on the main part 21 , and a corresponding round hole 222 is also provided on the accessory 22 . The 3 parts are linked together.

In addition, a functional hole 216 is also provided on the main part 21, and a functional hole 226 matching the functional hole 216 is also provided at the corresponding position of the accessory 22. Through the functional hole 216 and the functional hole 226, it is convenient to use when necessary. It is fixed together with the hole on the main keel 7 of the painted keel to prevent the hanging part 2 from moving in the direction of the top rib of the main keel of the painted keel.

Hanger 2 is used in the paint keel system of the ultra-low space ceiling. It is a brand-new direct hoisting ceiling system to replace the traditional indirect hoisting ceiling system, thereby reducing the cost of the ceiling and greatly saving the ceiling space.

In summary, the above are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention, All should be included within the protection scope of the present invention.
