Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to a sound insulation keel for building partition walls. Background Art

[0002] The keel for building partition walls is a commonly used building keel material. With the increasing requirements for the sound insulation effect of partition walls, the use of sound insulation keels has become more and more widespread. For example, patents CN209277341U, CN219732415U, CN219732415U, etc. all disclose sound insulation keels for building partition walls. The structure of these keels has a common feature that an H-shaped slot is set in the middle of the keel. The function of the H-shaped slot is to fix the sound insulation board to achieve the sound insulation function of the partition wall. During construction, the operator first fixes a sound insulation keel after fixing the ceiling and floor keels, and then inserts one end of the sound insulation board into the H-shaped slot of the sound insulation keel, and then sets the next sound insulation keel, and at the same time inserts the other end of the sound insulation board into the H-shaped slot of the sound insulation keel, and then completes the installation of subsequent sound insulation boards and sound insulation keels in sequence. Due to the limitation of H-shaped groove, the construction of the whole partition wall requires the installation of a sound insulation board after each sound insulation keel. Especially if the partition wall is high, the height of one sound insulation board is not enough, and two sound insulation boards need to be stacked to meet the height requirement of the partition wall. During the installation construction, at least two people are required to operate simultaneously to complete it, which makes the construction difficult. Summary of the invention

[0003] In order to solve the problems in the prior art, the utility model patent designs a sound insulation keel for building partition walls to solve the problem that the existing sound insulation keel is difficult to construct due to the limitation of the H-shaped groove in the middle.

[0004] The technical solution adopted by the utility model is that the sound insulation keel comprises a first supporting part and a second supporting part on both sides and a sound insulation part in the middle, and the sound insulation part is in an H-shaped structure.

[0005] Furthermore, the two sides of the sound insulation part are divided into an L-shaped part and a U-shaped groove part, forming an H-shaped structure, wherein the two side plates of the U-shaped groove part are respectively bent inward to form a clamping groove, the top of the clamping groove is bent into a plane, and the entire clamping groove is a trapezoidal protrusion.

[0006] Furthermore, the first supporting portion, the second supporting portion and the sound insulating portion of the sound insulating keel are integrally bent and formed.

[0007] As one of the designs, the first support portion and the second support portion are respectively bent in an S shape, the first support portion is located on the back side of the L-shaped portion of the sound insulation portion, the second support portion is located on the opening side of the L-shaped portion of the sound insulation portion, the connection between the second support portion and the sound insulation portion is bent one more time to form an inclined panel portion, and a plug-in transition cavity is formed between the inclined panel portion of the second support portion and the sound insulation portion.

[0008] As another design, the first supporting portion is bent in an S shape, the second supporting portion is bent in a C shape, the first supporting portion is connected to the L-shaped portion of the sound insulation portion, and the second supporting portion is connected to the U-shaped groove portion of the sound insulation portion.

[0009] As another design, the first support portion and the second support portion are respectively bent in an M shape, and the first support portion and the second support portion are both connected to the U-shaped groove portion of the sound insulation portion.

[0010] Furthermore, a plurality of resonance holes and threading holes are evenly distributed on the plate body of the sound insulation keel.

[0011] Furthermore, double-sided tape is adhered to the wall plate of the L-shaped portion of the sound insulation portion along the length direction.

[0012] Compared with the prior art, the improvement of the sound insulation keel for building partition walls designed by the utility model patent lies in that the sound insulation part in the middle of the sound insulation keel uses an h-shaped structure to replace the traditional H-shaped groove structure, and the two sides of the h-shaped structure are L-shaped and U-shaped respectively. When installing, all the sound insulation keels can be installed and fixed according to the design first, and then the sound insulation board can be installed. The construction of the entire partition wall can be completed by a single person, and the construction difficulty is small and the efficiency is high. The inclined panel part of the second supporting part of the ShZ-type sound insulation keel is bent to form a plug-in transition cavity. When installing the sound insulation board, first insert one end of the sound insulation board into the transition cavity of the sound insulation keel on one side, and then insert the other end of the sound insulation board into the U-shaped groove of the h-shaped structure of the sound insulation keel on the other side. At this time, the sound insulation board is removed from the plug-in transition cavity and directly attached to the L-shaped part of the h-shaped structure of the sound insulation keel. It is pre-fixed with double-sided tape and then further fixed with foam glue. The ShC and MhM-type sound insulation keels are also first completed according to the design when in use. All the sound insulation keels are installed, and then one end of the sound insulation board is inserted into the bending cavity of the second supporting part of the sound insulation keel on one side. At this time, the bending cavity of the second supporting part of the sound insulation keel on this side constitutes a transition cavity for the sound insulation board to be plugged in. Then, the other end of the sound insulation board is inserted into the U-shaped groove of the H-shaped structure of the sound insulation keel on the other side. At this time, the sound insulation board is removed from the bending cavity of the second supporting part of the sound insulation keel on this side, and is directly attached to the L-shaped part of the H-shaped structure of the sound insulation keel on this side. It is pre-fixed with double-sided tape and then further fixed with foam glue.

[0013] The two sides of the U-shaped groove of the sound insulation part are respectively formed with clamping grooves, which can clamp and fix the installed sound insulation board. The clamping groove can replace the traditional gluing construction, reduce the construction procedures, and ensure the stability of the sound insulation board installation. At the same time, the top of the clamping groove is bent into a plane, which increases the contact area between the clamping groove and the sound insulation board, and can further improve the sound insulation effect. The design of the resonance hole can improve the sound insulation effect of the keel itself, and the threading hole can be used for threading inside the partition wall, which is convenient for application.
