Description
Technical field
The invention belongs to construction engineering technical field, relate to a kind of heat insulation house surface material for building, the insulation roof slab that particularly has combining structure.
Background technology
Along with the growing tension of energy issue of world, the requirement of building energy conservation is more and clearer and more definite.Roofing is as the important composition part of architectural exterior-protecting construction, to the building energy-saving guaranteeing role that plays key up to standard.The progress of China's new countryside construction constantly highlights villages and small towns building energy conservation problem, and exploitation adapts to the village-town house building material product of China's actual conditions, is the key that realizes villages and small towns building environmental protection and economy.
The existing representative art document in this area comprises:
[1]: the exploitation of hard polyurethane foam core sandwich and application [J]. Wang Zhangzhong, Shen Zhiliang. chemical building material .2003.4:21-24.
The composite structural member with sandwich that the document proposes is that the panel material that adopts mainly contains materials such as composite panel such as metal sheets such as aluminium and steel, glass fiber reinforced plastic, glueds joint unicellular foamed plastic cores through sqtructural adhesives such as epoxide-resin glue, polyurethane adhesives and is made.
[2] " fiber-reinforced polymer cement based light thermal-insulation roof panel " patent No. ZL 200410010935.4
The insulation roof slab that this patented technology provides by condense in together upper and lower surface layer and the sandwich of layers between the surface layer form.Surface layer is to mix the fiber-reinforced polymer modified high-strength haydite concrete that forms by cement, flyash, haydite, polymer emulsion, organic short fiber, high efficiency water reducing agent, waterproof agent, blowing agent, exciting agent, water.The intermediate layer is the polymer modification foaming super-light aggregate concrete of cement, flyash, EPS particle, expanded perlite, haydite, polymer emulsion, interfacial agents, high efficiency water reducing agent, hydrophober, blowing agent, exciting agent, water mixing formation.
[3] " a kind of insulation roof slab and preparation method thereof ", the patent No.: ZL 20081001376503
The insulation roof slab that this patented technology provides is by the fixedly connected concrete layer of making in steel wire net rack skeleton both sides, make and form between the concrete layer on an empty stomach, fill insulant material forms insulation layer on an empty stomach, make it closely to link to each other with both sides concrete inwall, the embedding alkali-resistant glass fibre grid cloth in the outside of concrete, its preparation method is applicable to construction work by forming steel wire net rack skeleton, preparation concrete material, make the concrete layer, forming insulation layer four and go on foot and form.
The deficiency that complex heat-preservation plate technique that above-mentioned document provided exists has and comprises: (1) is sandwich structure, and the structural type of sheet material can be provided by surface layer fully, unreasonable structure; The bonding of surface layer and core can not guarantee, causes the globality of sheet material relatively poor; (2) surface layer all adopts solid slabs such as cement concrete or metal, causes sheet material from great; (3) the surface layer core is processed step by step, and manufacturing process is loaded down with trivial details relatively, and production integrated cost height is not suitable in the rural area and village-town house is promoted the use of.
Also comprise with the background technology of the application's association area: Dalian University of Technology has 4 of the patented technologies of autonomous property right: be connected hooked bar (ZL 99 3 42746.4) and combined building formwork net with tie bars (publication number 1364966) between the architectural lay wire production technology (ZL01128195.2) of construction process of concrete floor slab with steel wire net (ZL01138716.5), no stiffening rib, Mould net member.Can be used as the raw material that the invention provides as structure.
Macromolecule thermal insulation materials such as EPS, XPS, foamed phenolic resin are the energy-saving and heat-insulating materials of popularizing in the present building heat preservation system, SPF is one of heat-proof quality best material in the present solid heat-barrier material, its coefficient of thermal conductivity is low, 0.018-0.024W/ (m.K) only, be equivalent to half of EPS, these four kinds of organic thermal insulation materials are superior choosings of insulation in " combination lay wire insulation roof slab ".
In the existing raw material in China rural area, natural minerals such as trade waste such as slag, flyash and float stone, giant crystal stone, kaolin and agricultural product castoff (stalk etc.) source are abundant, cheap, if be used, have higher appreciation potential.Adopt these materials, through suitable technical finesse, can obtained performance satisfied foamed concrete thermal-insulating material, as the insulation in " combination lay wire insulation roof slab ".
Summary of the invention
The technical problem to be solved in the present invention is: a kind of insulation roof slab with structure-insulation combining structure is provided, solves the application of roofing heat insulating material in the building of villages and small towns.
Technical scheme of the present invention is:
The insulation roof slab of this combining structure mainly comprises structure, insulation two parts.Structure is made of architectural lay wire net sheet and lightgage steel joist, connects with self threading pin or rivet.The ridge keel are reserved intercommunicating pore, and the rib keel are established and reserved perforation.The ridge keel are passed the reservation perforation be connected to form the keel frame with the rib keel.Architectural lay wire net sheet is connected with the keel frame through self threading pin or rivet.Insulation adopts foam concrete, stalk foam concrete, pumice stone concrete, polyurathamc or foamed phenolic resin material, directly pours into a mould, is filled in the cavity of structure, and form continuous phase through intercommunicating pore.
Effect of the present invention and benefit are: make roof heat insulation rational in infrastructure, anabolic action is clear and definite, and manufacture craft is simple, is easy to realize industrialization production; The construction assembling is simple and convenient; Heat preservation and energy conservation effects is good, and bending resistance is strong, and constant product quality is with low cost, and the easy operating transportation is suitable for promoting the use of in the building of villages and small towns.
