Description
Technical Field
The invention relates to a construction method of a building roof, in particular to a positioning and waterproof integrated construction method of a solar foundation buttress of the roof.
Background
In recent years, roof solar water heaters are used in many areas and projects, the solar water heaters have complicated structures, dozens of users share one solar water heater, a large-area solar heat collecting and absorbing plate and other devices are needed, and the solar water heaters need to be fixed at special positions and overhead so as to absorb solar energy conveniently. Because the solar water heater is large in size and needs to be strictly fixed, the solar water heater needs to have a firmer foundation for preventing the solar water heater from being swayed and falling off by wind and preventing thermal expansion and cold contraction deformation. In order to fix the bracket, the buttress and the like, bolts need to be embedded in the roof or foundation bolts need to be constructed later. Not only is easy to fall off and is not beautiful, but also destroys the waterproof layer of the roof and brings great hidden trouble of water leakage to users.
For example, application No.: 200510044876.7A combined individual household support for solar water heater on loft slope roof, which is characterized by that the fixing support can be pre-embedded during roof construction, or installed on the roof by expansion bolts, and a waterproof layer is covered on the roof of the fixing support. This kind of structure just has the problem of destroying original roof waterproof layer, and waterproof layer once destroys, is difficult for the later stage to recover completely. And the mode of using the pre-buried bracket only adapts to the solar water heater with small volume and small mass used by a single user. Nowadays, buildings are higher and higher, and the specifications of solar water heaters are more and more increased. The problem of fixing a large-area solar water heater with the square meters of tens of meters is frequently encountered. The mode in the scheme is not suitable, for example, the support is easy to shake in a windy day, so that the deformation of the support influences the loosening of the embedded foundation, and a powerful supporting system is needed.

2. Paying off again before roofing engineering construction on roof concrete layer, confirm the concrete position of solar energy basis buttress, the solar energy basis buttress that designs divide into the buttress base of lower part and the construction of the support two parts on upper portion along the waterproof layer, pour the buttress base of lower part earlier, the elevation line control is under the waterproof roll material layer, the buttress base concrete placement of lower part accomplishes the back, the heat preservation of the whole roofing of successive layer construction, look for the slope layer, the screed-coat, guarantee lower part buttress base upper surface and screed-coat upper surface parallel and level, lay for the waterproof roll material layer and paste and provide the advantage.
3. Before the waterproof roll material layer of the roof is paved and pasted, firstly, the upper surface of the buttress base at the lower part is subjected to waterproof treatment, a cement crystal waterproof material is brushed within the range of 300mm outside the edge of the buttress base at the lower part to form a waterproof layer, after 24 hours, the waterproof roll material layer is paved and pasted on the whole roof to form the waterproof roll material layer, when the waterproof roll material is paved and pasted, firstly, the waterproof roll material layer is cut and rolled for standby according to the paving length and the elastic line size, the end heads of the roll material layer are aligned to the starting point of paving, and according to the elastic line, the two ends of a pipe center are held forward and slowly rolled and paved. The coiled material is paved and attached to the position of the reinforcing steel bar, the coiled material is cut off along the outer edge of the reinforcing steel bar, and then the paving and the attaching of the original coiled material are continued, so that the waterproof integrity is ensured. And after the waterproof paving of the coiled material is finished, sleeving a rubber water stop ring on 4 HRB 400-grade phi 8 steel bars, wherein the distance from the bottom surface is 20mm, and finally pouring a waterproof protective layer.
4. After the waterproof roll material layer and the waterproof protective layer are completed, firstly paving and pasting the roof tile according to BIM typesetting, reserving a buttress empty area at the buttress, reserving the thickness of the surface layer according to the size of the outer vertical surface of the buttress, pouring upper buttress concrete on the upper portion of the buttress foundation to form a support with the size of 260mm × 260mm, and finally paving and pasting the upper buttress tile on the outer surface of the support to complete the construction of the whole solar buttress.
Compared with the prior art, the waterproof integrated structure of the solar foundation buttress of the roof, which is obtained by the process construction, is constructed by dividing a large number of buttresses into an upper part and a lower part, so that the accuracy of the forming position is ensured, the integral attractiveness of the roof is ensured, and the waterproof coiled material is integrally paved at the buttresses and is not turned upwards and fixed. Buttress quantity is many among the roofing solar energy system, almost is covered with whole roofing, and application BIM technique confirms on the whole roofing that solar energy and some other structures and the whole of equipment arrange on the roofing itself, confirms the position of solar energy basis buttress, guarantees the whole pleasing to the eye optimal arrangement of roofing, under the prerequisite of guaranteeing service function, the roofing impression is effectual. The buttress is constructed in a layering mode, the waterproof coiled material is integrally paved and attached, the waterproof layer is fixed without being turned upwards, a bevel is not formed, the integral horizontal paving and attaching are achieved at the solar foundation buttress, construction is convenient, and the waterproof effect is easy to guarantee. Simple process, convenient operation, economy, applicability and good effect. The buttress base of solar energy basis buttress lower part is integrative to be poured into a mould the preparation and is connected with the support on upper portion through pre-buried reinforcing bar, and intensity is high, has strengthened solar rack's firm degree.
By applying the waterproof integrated construction method of the solar foundation buttress of the roof, the solar foundation buttress is orderly arranged on the roof, the appearance problem of the roof is solved, the waterproof is integrally paved, the construction method is simple, and the operability is strong; meanwhile, the solar buttress is prevented from damaging a roof waterproof layer and a roof surface layer brick.
