Abstract

The utility model relates to a wall-body heat-preservation building block, particularly to a porous foaming building block for heat preservation of a wall body. The heat-preservation building block is made by concrete foaming materials, and at least a long blind hole with a strip-shaped cross section is formed on the building block. The optimal method is to arrange a plurality of rows of strip-shaped long blind holes on the building block; and the heat-preservation building block adopting the design has the advantages that the properties of the concrete foaming materials can be performed, the existence of blind holes improves the thermo property of the building block, the heat resistance is enhanced, the masonry is facilitated during the construction, and the difficulty of the work is reduced.

Description

The porous, expanded building block of a kind of wall self-insulation

Technical field

The utility model relates to a kind of wall heat insulation building blocks, is specifically related to the porous, expanded building block of a kind of wall self-insulation.

Background technology

It is a fundamental state policy of China that wall changes with building energy conservation, and development was swift and violent in recent years.And mainly to take measures at present be the external heat preserving structure for exterior wall form.External heat insulating wall is compared following advantage with the outer body of wall of tradition: the one, can avoid producing heat bridge; The 2nd, agent structure is shielded; The 3rd, help keeping ambient-temp-stable; The 4th, help improving the indoor thermal environment quality; The 5th, be convenient to old building and carry out reducing energy consumption; The 6th, outer insulation can make the building appearance take on a new look greatly.

Existing external heat insulating wall all exists the characteristics of cost height and weatherability difference; in order to remedy this shortcoming; a kind of outer wall inner insulation material has appearred on the market; it is at the inboard one deck heat insulating material that covers of wall body structure; use cementing agent to be fixed on the wall body structure inboard; make topping and facing in the heat insulating material outside afterwards; though this mode has avoided occurring shortcomings such as weatherability difference; but it is bad and influence shortcomings such as resident's secondary decoration to occur heat insulation effect easily; and when existed building being carried out reducing energy consumption with it; daily life interference to the resident is bigger, and therefore this mode also can't effectively solve the existing existing variety of issue of wall thermal insulating.

Summary of the invention

At the existing many weak points of existing wall heat insulation material, the utility model provides a kind of wall heat insulation building blocks, be specifically related to the porous, expanded concrete block of a kind of wall self-insulation, this insulation blocks mainly adopts the concrete expanded material to make, this building block is provided with the long blind hole that at least one cross section is bar shaped, best mode is the bar shaped blind hole that many rows are set in building block uniformly, adopt the insulation blocks of this design, given full play to the characteristic of concrete expanded material, because the existence of blind hole has improved the thermal property of building block, has increased thermal resistance, building by laying bricks or stones when having made things convenient for construction simultaneously reduced the intensity of working.

The concrete technical scheme that the utility model adopts is: the porous, expanded concrete block of a kind of wall self-insulation, this building block are provided with the long blind hole that at least one cross section is bar shaped, and described long blind hole is arranged on the same surface of building block.

The utility model adopts this structure, be mainly used in the foamed concrete insulation blocks, this insulation blocks is with the intensive closed pore bubble formation block that is bound up, utilize airtight air as thermal resistance material, fabulous self-heat conserving effect is arranged, after adopting this structure, owing on same surface, be provided with long blind hole, under the condition that does not influence block structure intensity, significantly improved the thermal property of whole building block by long blind hole, increased the thermal resistance of building block, the building block than not adopting the blind hole design is greatly improved, the more efficiently self-heat conserving effect of bringing into play the foamed concrete insulation blocks, and do not need to add other heat insulating material in the blind hole, utilize the space in the blind hole to reduce the generation of cold and hot bridge, thereby realized better self-heat conserving effect.Adopt blind hole and do not adopt through hole, mainly consider when construction each blockhouse need to adopt cement mortar to carry out bonding, when adopting through hole, cement mortar is as easy as rolling off a log to enter building block inside by through hole, not only waste material but also can influence the heat insulation effect of building block, therefore select blind hole for use, only need during construction building block to be piled up building block according to the blind hole mode that Open Side Down and get final product with cement mortar is bonding.

Generally speaking, in order to play better self-heat conserving effect, many rows' bar shaped blind hole can be set in the foamed concrete building block uniformly, can better improve the thermal property of whole building block like this, thermal resistance is increased more uniformly, the unfavorable situation of partial insulation effect can not appear, and these blind holes are set uniformly, can guarantee the self structure intensity of building block, can not occur owing to the concentrated setting of blind hole causes block structure intensity to reduce, and finally cause the generation of phenomenons such as thermal insulation dehiscence; Why selecting cross section is the blind hole of bar shaped, is because the inventor finds through contrast back, and when adopting the blind hole of this shape, building block self structure intensity does not almost reduce, and its heat insulation effect also improves a lot than the blind hole of other shapes; Selected bar shaped blind hole length and width, can decide according to the model of place building block, three row's blind holes can be set in the building block of general 600 * 300 * 260mm, concrete decides on mode of occupation. and the length of blind hole is decided according to the size of building block, the general part of setting the blind hole non-through building block in bottom, its thickness is that 0.5-1.5cm gets final product, and preferred 1cm can guarantee the heat insulation effect and the structural strength of building block like this.

In sum, adopt the insulation blocks of this structure, given full play to the characteristic of concrete expanded material, because the existence of blind hole has improved the thermal property of building block, increased thermal resistance, building by laying bricks or stones when having made things convenient for construction simultaneously reduced the intensity of working.
