Problems solved by technology

For buildings with large-area steel frame structures on the roof, such as museums and gymnasiums, in addition to the repair obstacles caused by the large-area covered steel frame structures, they also have the characteristics of large building areas, which means that their roof areas are correspondingly larger. Large, and often have an overhead floor, once water seepage occurs, it is difficult to find out the real source of water leakage

Embodiment 1

[0051] Having a waterproof repair method of a large area of the roof steel structure 210, comprising the steps of:

[0052] S1 analysis roof structure: the roof structure is complex, such as figure 1 , Includes at least a large number of steel structure 210 of upright 211 consisting of flat roof 100 is disposed at the level of the roof;

[0053] . S2 of the roof structure to classify: The steel structure 210 and in contact therewith a corner portion of the flat roof classified as class has a planar structure and facade structure, the flat roof classified as having a flat planar structure of the class;

[0054] . S3 develop repair scheme: the overall roof repairs, such as figure 2 , For the first class of the plane to find the slope 310 of the first skin layer by extrusion plate laid waterproofing membrane 330, such as image 3 As shown in, for laying a double corner type is used for waterproofing repair manner, the inner layer comprising a waterproof membrane bilayer waterproofing ...

Embodiment 2

[0065] In order to further improve the reliability of water, such as image 3 As shown in this embodiment as a refinement of Example 1, except that: in the class include steel corner structure 210, the waterproofing membrane laid on the second surface 340 of post 211 extending surface laid over the flat roof, a first skin layer waterproofing membrane laid onto the flat 330 extending above the surface of a second roofing waterproofing membrane 340 is laid on the periphery of the pillar 211 above the flat roof, extruded sheet 310 is formed on a flat roof steel structure around 210 - in the first skin layer waterproofing membrane for waterproofing 320- 330- 340 at a second surface waterproofing oriented four by the superimposed structure, where a certain slope, it is possible to prevent water from the steel structure 210 a second vertical surface extending from the surface 340 waterproofing membrane laid the uppermost position, fall on the second surface of the waterproof membrane 340...

Embodiment 3

[0070] As a refinement of this embodiment, the above-described embodiment, except that: The Figure 5 As shown in step S1, the roof further comprises a roof laid flat in the patio 220, classified as a corner step S2 class 220 and further comprising a patio flat roof portion in contact therewith, such as Figure 6 ~ 8 , In the category include patio corner 220 waterproofing membrane is laid in layer 320 before contact with the flat roof and patio 220 pairs of flat roof surface excavation structural layer until the leakage level is reached so that the flat roof of the roof when a gap is formed between the surface 430 and 220 patio, laying the inner layer waterproofing membrane for waterproofing layer 320 in the intermediate portion 320 is press-fitted in the slit 430, i.e., the inner layer in the laying of the waterproofing membrane 320 in waterproofing membrane layer both ends of the sheet 320 are laid on the flat roof and facade patio 220 and leaving between the flat roof and facade...

Abstract

The invention discloses a waterproof repair method for a roof with a large-area steel frame structure. Through the overall analysis of the roof structure, it is determined to adopt the overall repair method to carry out waterproof repair on the roof to solve the problem of difficult investigation of water leakage and water seepage on large and complex roofs. The roof structure is classified in the way of partial crossing, the flat roof is divided into flat type as a whole, and the part of the flat roof close to the steel frame structure is classified into the corner type including the steel frame structure, which realizes the unity of overall and partial repair, which is beneficial Improve the stability of the repaired structure, thereby increasing its service life.

Description

Technical field [0001] The present invention relates to the field of waterproof repair, and more particularly to waterproof repair methods having a large-area steel frame structure roof. Background technique [0002] Whether it is tunnel, bridge, embankment, road, building or our daily house, waterproof is not to ignore problems. The main constructs of house buildings include foundations, walls, columns, floors, terrestrials, balconies, rains, stairs, doors and windows, buildings, etc., which are closely related to waterproof, wall, foundation, and ground, Door and windows, stairs, balconies and rain. Among them, the roof is at the top of the building, the main role is to prevent rain (snow) water, ultraviolet rays into the room and keep the room, heat insulation. Its configuration is mainly composed of a structural layer, a slope layer, a flat layer, a spacer layer, an insulation layer, a waterproof layer, a protective layer, a ventilation layer or a panel or the like. Due to th...
