Description

Lattice is without heat bridge self-insulating concrete sandwich wall board

Technical field

The present invention relates to a kind of new concrete warming plate, particularly relate to a kind of lattice of insulation board interface heat bridge effect of avoiding without heat bridge self-insulating concrete sandwich wall board.

Background technology

According to statistics, China's construction unit area energy consumption is still 3 ~ 5 times of the close developed country of weather.Building energy conservation be with the largest potentiality in various energy saving ways, the most directly, effective mode, be to alleviate the effective measures of energy-intensive.In building energy consumption, the energy consumption causing by exterior wall accounts for building the more than 50% of total energy consumption, thereby wall thermal insulating is the key that realizes building energy conservation.

Energy-saving wall has single energy-saving wall and two kinds of forms of composite energy-saving wall.Single energy-saving wall, take aerated concrete wall as representative, uses and develops because the problems such as safety, durability and use function hinder it.Composite energy-saving wall mainly comprises exterior wall internal insulation, external wall outer insulation and sandwich wall technology.Exterior wall internal insulation, because crack problem is serious, is difficult to avoid the shortcomings such as heat bridge, and proportion reduced year by year has become structural form a kind of transition, that fall behind.At present, the energy-saving wall that domestic and international application is the widest is external wall outer insulation.The endurance issues of China's external wall outer insulation engineering is very serious, cannot guarantee correct use and conventional maintenance condition under service life of 25 years, part engineering only can be used 3 ~ 5 years.Increasing expert recognizes external wall outer insulation project durability problem, worries that the catastrophic effect that nationwide large area or entirety are destroyed appears in external wall outer insulation engineering after the coming years or more than ten years.Sandwich wall is uniquely can reach the durability energy-saving wall that integrates load-bearing, insulation (sound insulation) and decorate, be suitable for different regions.At present, sandwich wall adopts modes such as filling benzene plate, and construction is complicated, long in time limit, the quality problems that easily occur in practice of construction, and this has affected further applying of this technology.Energy-saving wall insulation layer endurance issues has become the subject matter that the building energy conservation expert of China and foreign countries faces, seeks a kind of economy, construction simple and fast, good energy-conserving effect, insulation layer very urgent with the durability energy-saving wall technology in life-span with building.

At present the heat-insulation wall plate of research and development has China Patent No. 200710009733.1 to disclose a kind of name to be called " rendering-free combined lightweight thermal insulation wall plate " patent of invention; China Patent No. 200410037712.7 discloses the patent of invention that a kind of name is called " without cold bridge composite thermal insulation wall slab "; China Patent No. 200810157770.1 discloses a kind of name and has been called " a kind of insulating light wall slab and preparation method thereof " patent of invention; China Patent No. 200810157769.9 discloses the patent of invention that a kind of name is called " Yellow River mud insulating light wall slab and preparation method thereof "; China Patent No. 200810157768.4 discloses a kind of name and has been called " a kind of stalk light insulated wall board and preparation method thereof " patent of invention; China Patent No. 200910088404.X discloses the patent of invention that a kind of name is called " a kind of composite heat insulation wallboard and preparation method thereof "; China Patent No. 201010112851.7 discloses a kind of name and has been called " light composite insulating wall board " patent of invention; China Patent No. 200910008246.2 discloses the patent of invention that a kind of name is called " thermal insulation wallboard with new structure ".

But the fire safety problem of some heat-insulation wall plates is serious, the heat bridge of the seam crossing of some heat-insulation wall plates and the insulation of post cannot obtain fine solution always.

Summary of the invention

The present invention is directed to the technical problem of above-mentioned existence, provide a kind of insulation layer that does not adopt other just can avoid the non-insulation positions such as post, warming plate seam crossing with etc. the heat bridge effect at position, improve the heat insulation effect of exterior wall, effectively solve the problem of building energy conservation, and warming plate has good mechanical property, can be applicable to the lattice of requirement of different self heat insulation walls without heat bridge self-insulating concrete sandwich wall board.

The technical scheme of technical solution problem of the present invention is to achieve these goals:

Lattice, without heat bridge self-insulating concrete sandwich wall board, comprising: concrete cover, concrete intermediate interlayer and concrete rib, and what all there was a stairstepping interface at its two ends is intermediate plate; There is a stairstepping interface one end, and what the other end was straight port is end plate; What two ends were straight port is local plate; Described intermediate plate, end plate and local plate is and in concrete cover, is provided with two-layer sandwich insulating layer; Every layer of sandwich insulating layer longitudinally at least cut off by two concrete rib, and between concrete rib, is provided with longitudinal reinforcement net; Two-layer concrete rib staggers mutually, and every layer of sandwich insulating layer laterally at least cut off by two layer concrete intermediate interlayers, and is provided with transverse reinforcement net between concrete intermediate interlayer.

The thickness of described concrete cover is not less than 50 millimeters.

Described concrete intermediate interlayer and the thickness of concrete rib are not less than 40 millimeters.

The present invention compared with prior art has following advantages and effect:

The present invention has solved the insulation problem of heat bridge and the post of concrete insulation board seam crossing effectively, do not adopt other insulation layer just can avoid the non-insulation positions such as post, warming plate seam crossing with etc. the heat bridge effect at position, improve the heat insulation effect of exterior wall, effectively solve the problem of building energy conservation, and warming plate has good mechanical property, can be applicable to the requirement of different self heat insulation walls, and it is little to conduct oneself with dignity, material wastage rate is extremely low, does not produce building waste.Can effectively cut off the heat bridge of heat-insulation wall plate seam crossing, and avoid adopting other heat insulating material coupled columns to be incubated processing.
