Embodiment Construction

[0027] Such as figure 1 , it can be seen that the basic structure of the local unit of the stand, such as the prefabricated stand slab 1, the reinforced concrete inclined beam 2, the nylon fiber fine stone reinforced concrete surface layer 3 on the prefabricated slab stand slab and the circumferential slab requiring waterproof coating should be pre-designed before waterproofing Seam waterproof layer 4, longitudinal slab seam waterproof layer 5, the role of the concrete surface layer is to assist the waterproofing of the stands, surface decoration, and the base for fixing the seat brackets. In the concrete surface layer, steel bars 6 are bound, or embedded parts, fine stone Reinforced concrete reinforcement is Φ4@150 two-way, C20 fine stone concrete, nylon specification Φ25±3μm, length 16-19mm, breaking strength ≥ 25.9Cn, breaking elongation ≤ 60%, dosage 0.8kg / m3, when configuring concrete When it is added to the mixer together with other materials, the mixing time is 1 minute...

Abstract

This invention discloses a water-proof process method for precast slab bleachers including the following steps: clearing circuits between fixedly mounted precast slabs, sealing the chinks with fine concretes or cement mortars, processing the water-proof paints, processing reinforced concrete coat and processing the expansion joints, which gets the favourable result of applying a water-proof processing method of rigid and flexible combination.

Description

technical field [0001] The invention belongs to the waterproof technology in the construction field, in particular to a waterproof method for a prefabricated board stand. Background technique [0002] In the waterproof treatment of prefabricated slab stands such as stadiums, there are currently two main solutions in the construction industry, because the prefabricated stress slab itself can be considered to be impervious to water, so both solutions are aimed at the problem of water seepage in the gaps between prefabricated slabs. One is flexible waterproofing: that is, the method of covering the structural surface of the prefabricated slab stand with waterproof paint, and then pouring a layer of 40mm-60mm thick reinforced concrete surface layer, but this method does not take into account that the concrete surface layer of the stand needs to be covered. Install the seat bracket, and the bonding force between the concrete surface and the structure must be firm, so the waterpro...
