Description

Assembled high sound insulation cross keel

Technical Field

The utility model relates to a cross keel especially relates to a high sound insulation cross keel of assembled.

Background

With the development of modern industrial technology, building houses can be manufactured in batches and sets like machine production. Prefabricated building elements are assembled by transporting the prefabricated building elements to a construction site, so that the prefabricated building is interesting and can be realized.

The prefabricated building refers to a building assembled on a construction site by using prefabricated components. The building has the advantages of high building speed, less restriction by climatic conditions, labor saving and building quality improvement. One of indispensable components in the assembly type building is a wall body which is divided into an outer wall body and an inner wall body, and the outer wall body enables the building to form a semi-sealed state; the interior of the inner wall building is divided into a plurality of spaces, for example, a house is divided into spaces such as a kitchen, a bedroom, a living room, a toilet and a balcony through the inner wall, so that the living of people is met.

At present, the traditional indoor light high-sound-insulation wall body in the market is composed of keels, and comprises a ground keel arranged on the ground, a ceiling keel arranged above the ground keel and parallel to the ground keel and a vertical keel arranged between the ceiling keel and the ground keel. The existing light steel transverse keel of the indoor light wall only plays a role of fixing the vertical keel up and down, sound insulation performance is not processed, and the sound insulation performance is low.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems existing in the prior art, the utility model aims to provide a transverse keel applicable to an assembled high-sound-insulation wall body, which has high sound insulation performance and is convenient to install.

For realizing the utility model discloses a purpose, the utility model provides a cross keel include the bottom plate with set up in the curb plate of bottom plate both sides, the vertical U-shaped draw-in groove that sets up on the bottom plate, U-shaped draw-in groove both sides are equipped with microscler round head hole, the bottom plate bottom surface is close to both sides curb plate department and is equipped with the sound insulation filler strip.

Furthermore, the side plates on the two sides are connected with the bottom plate to form a bend.

Furthermore, the bottom surface of the bottom plate is bent inwards along two sides of the central line to form bulges, and U-shaped clamping grooves are formed between the bulges.

Furthermore, an inner sound insulation filler strip is arranged in the U-shaped clamping groove.

Furthermore, the long round-head holes are distributed on two sides of the U-shaped clamping groove in a halving mode, and a plurality of round-head holes are arranged side by side in an equidistant staggered mode.

The utility model has the advantages that:

1. the sound wave bridge breaking holes are processed at the two sides of the center of the bottom of the transverse keel, so that the conduction of sound waves is weakened, and the sound insulation performance of the whole partition wall is improved;

2. the sound wave is prevented from being conducted with the roof and the ground by arranging the sound insulation filler strips on the two sides of the bottom of the transverse keel, so that the sound insulation and vibration reduction performance of the whole building is improved;

3. the sound insulation performance of the whole wall body is further improved by arranging the U-shaped clamping groove in the middle of the bottom of the transverse keel and additionally arranging the sound insulation filler strip, inserting the sound insulation plate into the U-shaped clamping groove and blocking sound from being conducted in gaps among the ceiling keel, the ground keel and the sound insulation plate;

4. bending is formed on two sides of the U-shaped clamping groove, so that the strength of the keel is integrally enhanced, and the sound wave conduction direction is refracted, and the sound wave conduction is weakened.

5. The bridge cut-off holes are formed in the two sides of the middle of the bottom of the transverse keel, so that the installation, adjustment and fixation are facilitated.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, in the embodiment of the utility model, an assembled high sound insulation horizontal keel, including horizontal keel 1 and sound insulation filler strip 2, horizontal keel includes bottom plate 101 and set up in the curb plate 102 of bottom plate 101 both sides, the vertical U-shaped draw-in groove 3 that sets up on

bottom plate

101, 3 both sides of U-shaped draw-in groove are equipped with microscler round head hole 4, and bottom plate 101 bottom surface is close to both sides curb plate 102 department and is equipped with sound insulation filler strip 2, and both sides curb plate 102 is connected with bottom plate 101 and is formed bending 5, and sound insulation filler strip 2 is installed and is being bent 5
