Two ridge trifora hollow heat-insulation building blocks
Technical field
The utility model relates to a kind of light aggregate walling unit, specifically is a kind of pair of ridge trifora hollow heat-insulation building block, is used to construct the body of wall of various buildings.
Background technology
Existing a kind of light aggregate walling unit needs make insulation layer in wall outer side in addition as outer body of wall the time, and construction bothers very much, has increased cost; And insulation layer is easy and body of wall breaks away from, and also may be subjected to external influence and destruction, and application life is lower.
Summary of the invention
The purpose of this utility model just provides a kind of pair of ridge trifora hollow heat-insulation building block, with the construction trouble that the solution prior art exists, and the cost height, and insulation layer is easy and body of wall breaks away from the problem that application life is low.
The technical solution of the utility model is: comprise the main body of being made by light aggregate, it is characterized in that: described main body is an I-shaped structure, in the middle of two whippletrees of this I shape, be equipped with the whippletree through hole that communicates with its upper and lower end face, in the middle of the perpendicular thick stick of this I shape, be provided with the perpendicular thick stick through hole that communicates with its upper and lower end face.
In described whippletree through hole and in the waist groove of I shape, all be filled with light heat-insulating material.
Described light heat-insulating material is foamed polystyrene board (EPS).
Two ends at two whippletrees of described I shape are equipped with and the equidirectional arc groove of described whippletree through hole.
The utility model has the advantages that: utilize the cooperation of the whippletree through hole of I shape, perpendicular thick stick through hole and waist groove, prolonged the heat bridge between the body of wall ectonexine, improved the heat insulation and preservation effect of body of wall greatly; Fill insulant material can further improve heat insulation and preservation effect in through hole and groove; The arc groove that is located at two whippletree two ends and constitute cavity when building a wall and between the arc groove of adjacent block, improve effect of heat insulation, or between two whippletree two ends of adjacent block and arc groove filling concrete, increase body of wall in conjunction with firmness.

The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model is made by light aggregate, be I-shaped structure, centre at two whippletrees 1 of this I shape is equipped with the whippletree through hole 2 that communicates with its upper and lower end face, in the middle of two perpendicular thick sticks 3 of this I shape, be provided with 4, the two perpendicular thick sticks 3 of perpendicular thick stick through hole that communicate with its upper and lower end face and be equivalent to two spine.
In described whippletree through hole 2 and in the waist groove 5 of I shape, be filled with foamed polystyrene board (EPS) 7 and 8 respectively, or other light heat-insulating material for building.
Two ends at two whippletrees 1 of described I shape are equipped with and the equidirectional arc groove 6 of described whippletree through hole.
A typical appearance and size of the present utility model is 390mm * 240mm * 190mm.Also can determine the size of building block according to the actual conditions of body of wall.
The utility model is filled the foamed polystyrene board 8 of one in the hole that relative waist groove 5 constitutes between the adjacent block when using (referring to Fig. 2); Equal filled polystyrene foaming plate 7 in two whippletree through holes 2 of each building block.Can be vacant in the cavity that the arc groove 6 at two whippletree two ends constitutes, to improve effect of heat insulation; Also can be in the cavity that arc groove 6 constitutes and between the two whippletree two ends filling concrete 9, to increase the bond strength of body of wall.
Detection through national building engineering quality supervision inspection center, the quality of building block (heat-barrier material the is a foamed polystyrene board) combination that the utility model is shown in Figure 2, detection through national building engineering quality supervision inspection center, the testing result of its thermal resistance and thermal transmittance is respectively
Thermal resistance R=1.5m
2K/W,
Coefficient K=0.60W/ (m
2.K)
(concrete data are referring to the survey report that is numbered BETC-JN1-2008-38 of national building engineering quality supervision inspection center) meets the countries concerned's standard.
In addition, through building materials quality supervision and inspection station, Beijing to " presentation quality and permissible variation in dimension (number of non-compliances); strength grade (compressive strength); density rating; water absorption rate; contract with dry rate; relative moisture content of the present utility model, coefficient of softening, frost resistance (F25) " etc. project carried out checking (referring to the survey report that is numbered ZD2008-0062 at building materials quality supervision and inspection station, Beijing), its check conclusion is: above-mentioned Interventions Requested meet the index request of 3.5 strength grade certified products among the GB/T15229-2002 " Lightweight aggregate concrete small hollow block ".
