Description

Technical Field

[0001] The utility model belongs to the field of underground building construction, in particular to a double-layer plate structure for hospital clean room renovation engineering. Background Art

[0002] In various types of hospital buildings, especially in clean room renovation projects with cleanliness requirements, it is often encountered that the layout of the drawings after renovation is inconsistent with the layout of the original drawings, and even the medical use function of the renovation area changes. For example, the use function of the rooms without cleanliness requirements such as warehouses and toilets in the original drawing layout is changed to rooms with cleanliness requirements such as wards, operating rooms, ICUs, etc. According to the "General Hospital Building Design Code" GB51039-2014 6.1.2, "water supply and drainage pipes should not pass through the indoor overhead of clean rooms and important medical equipment rooms. If they must pass, leakage prevention measures should be taken." Therefore, the water supply and drainage pipes that meet the specifications in the original drawings no longer meet the specifications in the drawings after renovation due to the change in room use functions. However, the cost of re-changing the pipeline route is high, so a leakage prevention measure is required to deal with it. The conventional practice is to add a layer of structural plate under the original structural plate to form a double-layer plate structure.

[0003] In the existing conventional double-layer slab structure construction system, a new layer of reinforced concrete structural slab is added under the original water supply and drainage pipes to enclose the pipes inside, so that the water supply and drainage pipes are enclosed in the structure to avoid water leakage. However, this method has great limitations. Due to the large dead weight of the reinforced concrete slab, the structural beams on both sides need to be reinforced before construction. In addition, since the original structure has been completed during the renovation project, it is not easy to add a new closed structural slab under the original structure. It is necessary to plant reinforcement, support formwork, open the upper slab hole and then pour concrete. Not only is the process complicated, but because the concrete is formed in one piece, it is impossible to apply waterproof coating on the newly added structural slab later, and the construction quality and waterproof effect cannot be guaranteed.
