In one implementation, structural adhesive can be injected into the joints of the wood grain board 21 and the joints can be wiped with wood chips; in practical use, the joint of each wood grain board 21 is knotted with structural adhesive (such as glass cement), and before the structural adhesive is solidified, the joint is wiped by using the wood chips obtained when the wood grain boards 21 are processed, so that wood grains are formed on the surface of the joint and are integrated with the whole wood veneer; that is, compared with the prior art, the problem that a large gap exists at the splicing seam of the traditional template is solved by knotting the structural adhesive at the splicing seam, and the slurry leakage during concrete pouring is avoided; in addition, the joint is wiped by using the wood chips of the wood grain board 21 before the joint glue of the wood grain board 21 is not solidified, so that wood grains are formed on the surface of the joint, and the whole body is more attractive.
For reducing the construction careless leakage, the following construction key points are disclosed:
1. in order to ensure that the wood grain board 21 can be in natural arc transition, when the wood grain board 21 is constructed on site, the width of the wood grain board 21 is selected to be 300-600 mm, the wood grain board is paved and pasted along the direction with large transverse curvature, the length direction of the wood grain board 21 is paved and pasted along the longitudinal direction of a roof from one side to the opposite side in sequence, and the abutted seam height difference and the seam width meet the quality requirements of common template engineering.
Before the positioning and lofting of the roof embedded part, the point location facilities at each tail end can be rechecked, the positioning and lofting of the embedded part backing plate is started after the confirmation of no error, and the size deviation of the positioning of the embedded part is controlled within 10 mm.
After the roof texture board is paved and attached at the later stage, the biggest problem is finished product protection; therefore, during the reinforcement bar binding construction, the soles of field constructors must be cleaned in place, and if the field constructors wear antifouling shoes, the field constructors are strictly prohibited to discard and fall down pollutants to cause the pollution of the wood grain texture layer.
Considering construction in rainy season and cleaning of the wood grain board 21, a drain hole is arranged in advance in a low-lying position of the bottom of the roof, the position of the drain hole is arranged to follow a hidden position which is easy to drain or difficult to find in later vision, and when concrete is poured, the drain hole is closed.
After concrete pouring is finished, because the transverse curvature is large, multiple times of plastering and finishing are required, after several times of plastering and finishing, the concrete is immediately covered by a plastic film, so that moisture is not evaporated, and moisture preservation and maintenance are carried out by depending on the moisture of the concrete so as to ensure the color uniformity of the surface of the concrete. The roof concrete curing time is not less than the construction specification requirement, and meanwhile, a specially-assigned person is guaranteed to be arranged, and the roof concrete is cured and watered for 3 times every day.
The concrete base course is very important in the whole construction process link, the quality of the base course cleaning has very large influence on the whole effect of the fair-faced concrete, neutral cleaning agents are preferentially adopted for cleaning large-area floating dust treatment in the construction, and different treatment schemes are respectively adopted for different pollution categories.
Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the embodiments of the present application, and are not limited thereto; although the embodiments of the present application have been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
