High sound insulation assembled keel system for partition wall

Abstract

This utility model discloses a high sound insulation prefabricated keel system for partition walls, including at least one edge keel and several frame keels. Adjacent frame keels and edge keels are connected by screws. The side walls of both frame keels and edge keels are provided with stepped concave sealing grooves. The sealing grooves are provided with sound insulation pads for sound insulation and to hide the screw heads. Both frame keels and edge keels are provided with cavities and board cavities, and both frame keels and edge keels are integrally bent and formed. The anti-directional double cavity keel design combined with the elastic connection method effectively blocks the direct propagation path of sound between keels, significantly eliminating the sound bridge phenomenon and significantly improving the sound insulation of the wall. The stepped sealing grooves with built-in sound insulation pads and weak bridge holes simultaneously hide the screw heads and extend the sound wave transmission path, thereby eliminating the risk of sound leakage at the installation nodes. The V-shaped anti-bending ridge optimization significantly improves the bending strength of the keel while maintaining the standard thickness.

Description

Technical Field

[0001] This utility model relates to the field of partition wall keel technology, specifically to a high sound insulation prefabricated keel system for partition walls. Background Technology

[0002] In modern building interior partition wall construction, the light steel keel system is widely used due to its lightweight, high strength, and ease of construction. However, traditional keel structures have a significant sound insulation bottleneck: sound waves easily form "sound bridges" through rigidly connected keels, leading to efficient noise transmission between walls and failing to meet increasingly stringent requirements for acoustic environment quality. Existing improvement solutions mostly rely on simply adding sound insulation cotton or using complex double-layer keels, which not only increases wall thickness and material costs but also involves cumbersome on-site assembly procedures and difficulty in ensuring precision, negatively impacting construction efficiency and wall flatness. Furthermore, improper handling of screw installation positions in conventional keel structures can easily create additional sound bridge channels, further restricting the improvement of sound insulation performance.

[0003] To address the aforementioned issues, while some technologies attempt to weaken the sound bridge effect through elastic clamps or localized filling, their effectiveness is limited and structural reliability is insufficient. For example, elastic connectors are prone to aging and failure, affecting the long-term stability of the wall; while ordinary cavity designs lack effective blocking of sound wave propagation paths, failing to significantly improve sound insulation. Furthermore, the standard specifications of keel in the market are uniform; the frame keel, as the main load-bearing component, and the edge keel used for boundary transitions often use the same cross-section, making it difficult to balance structural strength with the need for refined acoustic optimization, resulting in difficulties in coordinating sound insulation performance and construction efficiency.
