Description
Technical Field
The utility model belongs to the technical field of steel construction building and specifically relates to a steel construction roofing waterproof construction is related to.
Background
Compared with the traditional concrete building, the steel plate or the section steel replaces reinforced concrete, so that the steel structure building has higher strength and better shock resistance. And because the components can be manufactured in factories and installed on site, the construction period is greatly reduced. Because the steel can be repeatedly used, the construction waste can be greatly reduced, and the steel is more environment-friendly, so the steel is widely adopted by all countries in the world and is applied to industrial buildings and civil buildings. At present, the application of steel structure buildings on high-rise and super high-rise buildings is mature day by day, and the steel structure buildings gradually become mainstream building processes, and are the development direction of buildings in the future.
However, most of the existing roofs of steel structure buildings are waterproof layers, insulating layers and supporting beams. If leakage occurs at a certain position of the waterproof layer, water can directly reach the heat-insulating layer and gradually flow to other parts of the roof, so that water leakage occurs on the roof, and heat insulation failure of the heat-insulating layer of the roof is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a construction is simple and convenient, can prefabricate, keep warm thermal-insulated effectual and the lasting steel construction roofing waterproof construction of water-proof effects.
The purpose of the utility model is realized like this: the utility model provides a steel construction roofing waterproof construction, from inside to outside include the girder steel in proper order, the purlin, the zinc steel sheet of aluminizing, the rock wool heat preservation, first connecting screw passes the rock wool heat preservation from outside to inside in proper order, the zinc steel sheet of aluminizing, the purlin is fixed on the girder steel, rock wool heat preservation outside covers there is TPO waterproofing membrane, the overlap joint width D1 of waterproofing membrane overlap joint position is not less than 120mm, waterproofing membrane overlap joint position inboard is equipped with second connecting screw, the second connecting screw passes the rock wool heat preservation and fixes on the purlin, waterproofing membrane overlap joint position outside is through hot-blast welded seal, the width D2 of welded seal section is not less than 40 mm. The utility model discloses a steel construction roofing waterproof construction can realize the factory's modularization production, simplifies the site operation step to have advantages such as light is high-efficient, heat preservation is thermal-insulated and waterproof performance is superior.
As the utility model discloses a further improvement, rock wool heat preservation surface paste has the non-woven fabrics isolation layer, when improving the thermal-insulated effect of roofing heat preservation, has certain flexibility, prevents the heat preservation aspect fracture.
As a further improvement, the rock wool heat preservation internal surface paste has PE membrane steam trap, further improves roofing waterproof performance.
As a further improvement, rock wool heat preservation thickness is 100mm, and PE membrane steam barrier layer thickness is 0.3mm, and aluminized zinc steel sheet thickness is 0.8mm, and waterproofing membrane thickness is 1.5mm, when guaranteeing roofing waterproof performance, has higher price/performance ratio.
As a further improvement, the purlin adopts the wave steel sheet for the connection of each layer of roofing has certain flexibility, prevents to warp because of the roofing that reasons such as environmental factor lead to, and hookup location is not hard up, the fracture, further avoids the roofing to leak.
As a further improvement, the rock wool heat preservation layer is divided into an inner layer and an outer layer, and the staggered joint between the two layers is arranged, so that no gap exists between the plates, and a better heat preservation effect is achieved.
Drawings
Fig. 1 is the utility model discloses a steel construction roofing waterproof construction's schematic diagram.
The novel waterproof plate comprises a steel beam 1, a purline 2, an aluminum-zinc plated steel plate 3, a rock wool heat preservation layer 4, a first connecting screw 5, a waterproof coiled material 6 and a second connecting screw 7.
Detailed Description
The steel structure roof waterproof structure shown in fig. 1 sequentially comprises a steel beam 1, a purline 2, an aluminum-zinc-plated steel plate 3 and a rock wool heat-insulating layer 4 from inside to outside. The purline 2 is made of wave-shaped steel plates. The rock wool heat preservation layer 4 is divided into an inner layer and an outer layer, and the two layers are arranged in a staggered joint mode. The outer surface of the rock wool heat preservation layer 4 is pasted with a non-woven fabric isolation layer, and the inner surface of the rock wool heat preservation layer 4 is pasted with a PE film steam-proof layer.
The first connecting screw 5 sequentially penetrates through the rock wool heat-insulating layer 4, the aluminum-zinc-plated steel plate 3 and the purline 2 from outside to inside and is fixed on the steel beam 1. And the outer side of the rock wool heat-insulating layer 4 is covered with a waterproof coiled material 6. Lapping width D1 of 6 overlap joint positions of waterproofing membrane is not less than 120mm, and 6 overlap joint position inboards of TPO waterproofing membrane are equipped with second connecting screw 7, and second connecting screw 7 passes rock wool heat preservation 4 and fixes on purlin 2, and the 6 overlap joint position outsides of TPO waterproofing membrane are sealed through hot-blast welding, and the width D2 of welding seal section is not less than 40 mm.
