Background technology
At present, building brick generally is divided into two kinds of solid loam brick and hollow building blocks.Though loam brick is made simply, cost is low, assemble convenience, there is major defects such as to expend a large amount of land resourcess, destruction ecological environment.Building-block commonly used uses concrete to be raw material, solved loam brick and ruined the problem that take up an area of in the field, but insulation, effect of heat insulation is relatively poor, is difficult to satisfy the new dwelling construction standard of national energy-conserving and environment-protective reduction of discharging.The external wall that has adopts the mode of pasting heat insulating material to reach energy conservation standard, not only can increase operation, prolongs the construction period, and heat insulation, heat preservation effect is unsatisfactory.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of energy-conserving and environment-protective composite heat insulation block.
The technical solution of the utility model is as follows: a kind of composite heat insulation block, has building block body, this building block body is a rectangular structure, its key is: offer five hollow holes that connect its upper and lower end face on described building block body, these five hollow holes are strip, and four hollow holes wherein are by matrix distribution, and another hollow hole is positioned at the centre of matrix, and with other four dislocation, in the hollow hole of centre, be embedded with the thermal insulation body.
The utility model is by being provided with five hollow holes that are similar to quincunx distribution on building block body, and in a middle hollow hole, the thermal insulation body is set, after assembling into body of wall like this, that the thermal insulation body can be brought into play is heat insulation, the effect of insulation, can outdoor high heat energy obstruct be converted in the low heat energy inlet chamber in summer, to reduce interior temperature; Can reduce the loss of heating of house heat in winter, arrive the effect of insulation.Four hollow holes of matrix distribution can alleviate the weight of building block body on the one hand, save material, and on the other hand, the air in these four hollow holes also can play certain heat insulation, insulation effect.
In order to reach better heat insulation, heat insulation effect, offer groove at the middle part of above-mentioned building block body two sides, this groove connects the upper and lower end face to building block body, and also is embedded with the thermal insulation body in the groove.
Selection for convenience, to adapt to the needs of different building requirements, above-mentioned thermal insulation body is EPS polyphenyl plate or XPS plate or polyurethane plate or the sticking rock beam of expansion concrete or vitrified micro-bead heat preserving plate or compound silicate board or pouring thermal insulation mortar.
Beneficial effect: the utlity model has lightweight, heat insulation, be incubated, be convenient to build by laying bricks or stones, save characteristics such as work efficiency, energy conservation, environmental protection, reach 65% energy-saving index of national requirements after testing, and produce energy-conservationly, use energy-conservationly, be that binodal can product.Various performance of the present utility model is better than general light aggregate ordinary concrete building block, and every square of cost is also pasted heat insulating material cost savings 60% than exterior wall, is a kind of economical and practical insulation blocks.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, a kind of composite heat insulation block, have building block body 1, this building block body 1 is a rectangular structure, offers five hollow holes 2 that connect its upper and lower end face on building block body 1, these five hollow holes 2 are elongated rectangular shape, the long limit of rectangle parallels with the length direction of building block body 1, and four hollow holes 2 wherein are by matrix distribution, and another hollow hole 2 is positioned at the centre of matrix, and with other four dislocation, in the hollow hole 2 of centre, be embedded with thermal insulation body 3.Middle part in described building block body 1 two sides offers groove, and this groove connects the upper and lower end face to building block body 1, and also is embedded with thermal insulation body 3 in the groove.According to the requirement of different buildings, described thermal insulation body 3 can be selected EPS polyphenyl plate or XPS plate or polyurethane plate or the sticking rock beam of expansion concrete or vitrified micro-bead heat preserving plate or compound silicate board or pouring thermal insulation mortar etc. for use.
