Abstract
A water-proof layer compounded by netted or fibrous grain water-proof coiled material and non-dry concreted soil relates to a product which is made by water-proof position of cast-in-place concrete structure and prefabricated concrete member, the surface of the existing building or prefabricated member is made into water-proof coiled material after concrete is solidified, the surface of the pre-paved water-proof coiled material is coated with sand, in order to raise the binding fastness of water-proof coiled material and concrete, the netted or fibrous grain fabric is paved on the surface of the non-dry concrete to achieve mutual firm binding, then the binding fastness of the chemical fiber fabric and water-proof coiled material or water-proof plastic plate is far greater than that of sand and viscous water-proof coiled material, the middle binding material of sand is changed into netted or fibrous fabric, so that the water-proof coiled material and concrete can be more firmly bound, and the water-proof quality is better and longer, also provides various processes of pre-paving, post-paving, engineering cast-in-place and factory prefabrication.
Description
Technical Field
A waterproof layer compounded by a reticular or fiber-grained waterproof coiled material and un-dry-mixed concrete relates to the waterproof field of buildings, municipal works and the like, in particular to a product which is required to be made into a waterproof part of a cast-in-place concrete structure and a prefabricated concrete member.
Background
The invention relates to a waterproof coiled material which is required to be made on the surface of the existing building or prefabricated part, wherein the waterproof coiled material is constructed on the surface after the concrete is solidified, wet concrete is poured on the waterproof coiled material which is arranged on the bottom plate and the wall surface of the underground engineering, sand is sprayed on the surface of a sticky coiled material, the sand is combined with the concrete and the sand is combined with the sticky waterproof coiled material, and the technology is developed in order to improve the combination fastness of the waterproof coiled material and the concrete and apply the combination of the undried concrete and the waterproof coiled material to other parts needing water prevention.
Disclosure of Invention
Firstly, the net-shaped or fiber-grain-shaped fabric is paved on the surface of the undried concrete to achieve mutual firm combination, then the hot-melt compounding or the bonding firmness of the chemical fiber fabric and the waterproof coiled material or the waterproof plastic board is far higher than the combination of the sand and the viscous waterproof coiled material, and the combination of the fabric and the undried concrete is far higher than the combination of the sand and the undried concrete. The invention discloses a waterproof layer compounded by a reticular or fiber-grained waterproof coiled material and non-dry concrete, which comprises the following steps:
s11, bonding the chemical fiber fabric with the waterproof roll into a whole by hot melting or a chemical agent, and combining the waterproof roll with the concrete surface;
s12, when the waterproof coiled material is used for an external wall and a bottom plate of an underground project, the waterproof coiled material is paved first and then concrete is poured;
s13, when the waterproof coiled material is used for a roof and a roof, the waterproof coiled material is paved and combined with the concrete together for curing when the concrete is not dried;
s14, when it is used to prefabricate concrete member, according to the pouring mode of the waterproofing surface and prefabricate mould, it can adopt the above S12 or S13 two construction methods.
The waterproof layer compounded by the reticular or fiber-grained waterproof coiled material and the non-dry concrete further comprises the following steps according to the method for overlapping and connecting the pre-paved waterproof layer and the post-paved waterproof layer with corresponding side openings:
s21, when the construction method S12 is adopted, the edges of the waterproof coiled materials are mutually overlapped and are welded into a whole by a climbing welder;
s22, when the construction method S13 is adopted, the edge of the waterproof coiled material is subjected to flat joint construction, after the concrete is solidified and dried, a pure waterproof coiled material is added to cover the flat joint position, and the pure waterproof coiled material is welded into a whole by a creeping welding machine;
s23, when using prefabricated parts, using the overlapping of S21 when using S12 construction, using the method of adding a coil after flat seam of S22 when using S13 construction.
The invention has the advantages that the middle binding material of the sand is changed into the reticular or fibrous fabric, so that the waterproof coiled material and the concrete are combined more firmly, and the waterproof quality is better and longer, and various processes of pre-paving, post-paving, engineering cast-in-place and factory prefabrication are provided.
Drawings
FIG. 1 is a sectional view of a waterproof roll laid first and then concrete poured;
figure 2 is a cross section of a waterproof roll cast first with concrete and then laid while not dry.
Detailed Description
In the figure 1, a section of chemical fiber fabric 2 in a net shape or a fiber pattern shape is combined into a whole on the surface of a waterproof coiled material 1 by production processes such as hot pressing and the like, the edge openings without the chemical fiber fabric are reserved for being overlapped and hot welded 4, and then a concrete surface layer 3 (such as the part of an underground engineering bottom plate) is poured.
FIG. 2 is a concrete surface layer 3 which is poured first, a waterproof coiled material 1 is laid before drying, the chemical fiber fabric 2 with the surface being reticular or fiber texture is combined with the concrete, the waterproof coiled material is in a flat joint, after the concrete is cured and dried, a waterproof coiled material 5 is covered on the flat joint and is connected by a creeping welder through hot welding.
