Description

Technical Field

[0001] This utility model relates to the field of building suspension technology, and in particular to a special suspension connector and suspension system for a narrow-mouth steel deck plate. Background Technology

[0002] During the construction process, ceilings, water and electricity pipes, air conditioning pipes, and other mechanical and electrical equipment need to be suspended and installed on the floor slab.

[0003] Existing suspended ceilings require advance planning or pre-installation when suspending air conditioning ducts, water and electricity lines, and certain equipment. Installation involves drilling holes in the bottom of the floor slab for expansion bolts, welding, or using explosives to drive nails. This construction process is complex, inflexible, time-consuming, and noisy. It can easily damage the reinforced concrete of the floor slab, and may even penetrate the slab or damage the bottom reinforcing steel, causing structural damage and creating safety hazards. Figure 1 As shown, this is the existing technology of drilling holes at the bottom of the floor slab and inserting expansion bolts. This type of connection has poor flexibility, requires pre-embedding, has a long construction period, generates a lot of construction noise, and can easily damage the quality of the reinforced concrete of the floor slab. It may even drill through the floor slab or damage the bottom reinforcement of the floor slab, causing damage to the structure and creating safety hazards. Utility Model Content

It is convenient to construct, cost-effective, and maintenance-free, and can be applied to the installation of ceilings, water and electricity pipes, air conditioning pipes, and other electromechanical equipment. No pre-embedding is required, and the construction process avoids drilling, welding, or using explosives to drive nails into the bottom of the floor decking. After installation, it can be moved, removed, or reinstalled, and the installation process produces almost no noise pollution.
