Abstract
The utility model relates to a self-temperature-preservation cement block which comprises a cement block body. A plurality of rows of through holes which are distributed at intervals are formed on the cement block body, and each row comprises at least two through holes; and the adjacent two rows of through holes are staggered. The self-temperature-preservation cement block has a good temperature-preservation effect, and has low heat transfer coefficient.
Description
Technical field
The utility model relates to the technical field of constructional materials, especially a kind of self-heat conserving cement block.
Background technology
In recent years, flourish along with China's economic construction, building trade has also obtained significant progress.Because it is lightweight that hollow brick has, the advantage of insulation is so be widely used in the building trade.
Yet the every exhausting hole on the building-block that uses at present all is alignment to be arranged, although it has certain heat insulation effect, but in the identical situation of block thickness, the two sides of its heat transfer direction are straight line through the heat transfer path of building block, so that heat insulation effect fails to reach optimum state; Through hole on the simultaneously present building-block is circular hole, and circular hole has minimum girth, so its porosity is lower, the entity part proportion is larger, the thermal transmittance of building block so this has also increased the thermal transmittance of building block, has reduced the effect of insulation greater than the thermal transmittance of air in addition.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the problem that proposes in the above-mentioned background technology, the utility model provides a kind of self-heat conserving cement block, the high insulating effect of this self-heat conserving cement block, and thermal transmittance is low.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of self-heat conserving cement block, has the cement block body, offer the through hole that number row equidistantly distributes on the cement block body, every exhausting hole is at least two, the setting that is staggered of adjacent two rows' through holes.
Further: the cross section of through hole is regular hexagon.
The beneficial effects of the utility model: adjacent two rows' the through holes setting that is staggered on the self-heat conserving cement block of the present utility model, in the identical situation of block thickness, the two sides of its heat transfer direction are broken line through the heat transfer path of building block, heat transfer path is elongated, reduced thermal transmittance, so that heat insulation effect becomes better, these through holes are the regular hexagon hole simultaneously, the former circular hole of comparing, the regular hexagon hole has longer girth under condition of the same area, so the porosity of this building block is large, the entity part proportion is less, has further improved the effect of insulation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Among the figure 1, the cement block body, 2, through hole.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Self-heat conserving cement block as shown in Figure 1 has cement block body 1, offers the through hole 2 that number row equidistantly distributes on the cement block body 1, and every exhausting hole 2 is at least two, the setting that is staggered of adjacent two rows' through holes 2.Wherein the cross section of through hole 2 is regular hexagon.
Adjacent two rows' through holes 2 setting that is staggered on this self-heat conserving cement block, in the identical situation of block thickness, the two sides of its heat transfer direction are broken line through the heat transfer path of building block, heat transfer path is elongated, reduced thermal transmittance, so that heat insulation effect becomes better, these through holes 2 are the regular hexagon hole simultaneously, the former circular hole of comparing, the regular hexagon hole has longer girth under condition of the same area, so the porosity of this building block is large, the entity part proportion is less, has further improved the effect of insulation.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the manual, must determine its technical scope according to the claim scope.
