Abstract
The invention discloses an anti crack method for the top surface of a building. In the process of concrete casting construction of top surfaces of the building, a double layered bamboo wool net is flatly laid out in the concrete, so that the water proof construction in top surfaces of the building is only limited in periphery and corners of the top of the building, thus, the water proof construction investment of the top of the building is reduced to a large extent.
Description
Technical field
The present invention relates to the storied building top surface construction technology, particularly a kind of method that prevents the storied building top surface crackle with bamboo reinforcement.
Background technology
Storied building top surface since winter and summer and round the clock between the temperature difference, under the effect of expanding with heat and contract with cold repeatedly, be easy to crack, thereby cause the seepage of roof rain water, because some fine cracks is indiscoverable with naked eyes only, so both very bothered effect bad when repairing.Adopt full waterproof measure to address this problem preferably at storied building top surface, but investment and construction cost are very high.
Summary of the invention
The purpose of this invention is to provide a kind of storied building top surface crack preventing method, leak, and reduce the investment of storied building top surface waterproofing simultaneously significantly to prevent the storied building top surface crackle.
The object of the present invention is achieved like this: when storied building top surface is constructed operation to the casting cement mortar, bamboo reinforcement net at twice tiles in cement mortar, make two-layer bamboo reinforcement net finally all be sealed in the concrete, upper strata bamboo reinforcement net is apart from concrete upper surface 3～5mm, upper and lower two-layer bamboo reinforcement net is at a distance of 8～10mm, and the cross-sectional area that constitutes the single bamboo silk of upper strata bamboo reinforcement net is 2～3mm
2, the eyelet of upper strata bamboo reinforcement net is the square of length of side 10mm, the bamboo sliver transvers section of formation lower floor bamboo reinforcement net is long-pending to be 15～20mm
2, its eyelet is the square of length of side 3cm, to the periphery and the corner of storied building top surface, then still routinely waterproof measure is handled.
Adopt such scheme can receive following remarkable result:
1, owing to bamboo silk, bamboo bar not only have good toughness and tensile strength, and and cement between fabulous cohesive and adhesive power are arranged, so when itself and concrete are become one, the outstanding concrete cracking resistance line ability of fragility is strengthened greatly, under the effect of double-deck bamboo reinforcement, can avoid the generation of storied building top surface crackle fully, make the waterproof construction of storied building top surface only be confined to periphery and corner, because the bamboo reinforcement net is cheap and easy to get, spreadability good, construction is easy, thereby can reduce the investment of roof waterproofing significantly.
2, the relevant parameter and the permanent position of the bamboo reinforcement net of the employing of this programme can be taken into account necessary toughness simultaneously, and tensile strength is to the transparency of cement mortar, the facility of construction and the planarization of storied building top surface.
3, since the bamboo reinforcement net be sealed in the concrete, thoroughly isolated with air, thus can rotten sex change, thereby make the cracking resistance line performance of storied building top surface prolonged constant.
Claims (1)
1. storied building top surface crack preventing method, it is characterized in that: when storied building top surface is constructed operation to the casting cement mortar, bamboo reinforcement net at twice tiles in cement mortar, make two-layer bamboo reinforcement net finally all be sealed in the concrete, upper strata bamboo reinforcement net is apart from concrete upper surface 3～5mm, upper and lower two-layer bamboo reinforcement net is at a distance of 8～10mm, and the cross-sectional area that constitutes the single bamboo silk of upper strata bamboo reinforcement net is 2～3mm
2, the eyelet of upper strata bamboo reinforcement net is the square of length of side 10mm, the bamboo sliver transvers section of formation lower floor bamboo reinforcement net is long-pending to be 15～20mm
2, its eyelet is the square of length of side 3cm, to the periphery and the corner of storied building top surface, then still routinely waterproof measure is handled.
