Abstract
The utility model provides an external wall heat insulation hollow block which can achieve self heat insulation and is high in construction efficiency and low in cost, relating to the improvement of the structure of the external wall heat insulation hollow block. The heat insulation hollow block comprises a block body and is structurally characterized in that a first vertical through hole with horizontal stripe shaped cross section is arranged in the front of the block body; and vertical straight slots which cut off a cold bridge are arranged on the two sides of the rear of the block body, corresponding to the first vertical through hole.
Description
Technical field
The utility model relates to exterior-wall heat insulation hollow building block structured and improves.
Background technology
The structure of existing building-block is generally the middle part and has a through hole, and there is cold bridge in the building block two ends like this, can not solve self-heat conserving in building is used; The heat preserving mode of therefore existing exterior wall is all outer insulation, and there are the following problems.
1, external wall outer insulation easily takes off and splits, hollowing, seeps water, comes off.
2, easily use inferior materials and turn out substandard goods in the construction.
3, construction cost is high.
Summary of the invention
The utility model is exactly for the problems referred to above, and a kind of self-heat conserving of realizing is provided, the exterior-wall heat insulation building-block that efficiency of construction is high, cost is low.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises building block body, and its structural feature building block body front portion is provided with the first vertical through holes that cross section is the horizontal stripe shape, and both sides, building block body rear portion are provided with the vertical groove that cuts off cold bridge corresponding to the first vertical through holes.
As a kind of preferred version, building block body described in the utility model is cuboid.
As another kind of preferred version, the first vertical through holes described in the utility model is rectangle.
As another kind of preferred version, vertical groove described in the utility model is rectangle.
As another kind of preferred version, be provided with the second vertical through holes between vertical groove described in the utility model.
Secondly, the second vertical through holes described in the utility model is rectangle.
In addition, building block body described in the utility model is the silicate concrete body.
The utility model beneficial effect.
Both sides, the utility model building block body rear portion are provided with the vertical groove that cuts off cold bridge corresponding to the first vertical through holes, namely the horizontal projection of the first vertical through holes has intersection with the horizontal projection of vertical groove, can cut off the cold bridge of building block both sides; Therefore the utility model can be realized self-heat conserving, save the energy and reach 65% standard, the efficient more than 60% of building the exterior wall duration by laying bricks or stones is shortened in it goes without doing under construction outer insulation and outer fire prevention, can reduce under construction, integrated cost, make the same life-span of insulation blocks and whole building.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described further.The utility model protection domain not only is confined to the statement of following content.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model top view.
In figure, 1 is that the first vertical through holes, 2 is that building block body, 3 is that the second vertical through holes, 4 is vertical groove.
The specific embodiment
As shown in the figure, the utility model comprises building block body 2, and building block body 2 front portions are provided with the first vertical through holes 1 that cross section is the horizontal stripe shape, and building block body 2 both sides, rear portion are provided with the vertical groove 4 that cuts off cold bridge corresponding to the first vertical through holes 1.
Described building block body 2 is cuboid.
Described the first vertical through holes 1 is rectangle.
Described vertical groove 4 is rectangle.
Be provided with the second vertical through holes 3 between described vertical groove 4.The second vertical through holes 3 is set alleviates the weight of building block, and can further improve heat insulation effect.
Described the second vertical through holes 3 is rectangle.
Described building block body 2 is the silicate concrete body.
Described the first vertical through holes 1, vertical groove 4, the second vertical through holes 3 is interior all can insert heat insulating material, as benzene plate or extruded sheet (XPS) etc.
15000 of the utility model experiments, the below is testing result.
Be understandable that, above about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can modify or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
