Abstract
The invention discloses a bridge-cut-off composite self-thermal insulation block, belongs to the field of architectural technology, and especially belongs to the field of brick and block structure of building walls. Characteristics of the bridge-cut-off composite self-thermal insulation block are that, a plurality of through holes are arranged in a block body along the height direction; a polyurethane foam hole is arranged in the middle part of the block body, wherein the polyurethane foam hole and the through holes are parallel, the depth of the polyurethane foam hole and the height of the block body are identical, the length of the polyurethane foam hole is less than the length of the block body, and distances are designed between the ends of the polyurethane foam hole in the length direction and corresponding ends of the block body in the length direction respectively; and a rigid polyurethane foam layer is arranged in the polyurethane foam hole. The bridge-cut-off composite self-thermal insulation block possesses excellent cohesiveness and heat retaining property, is convenient for production and construction, and is capable of increasing the integral strength of exterior wall systems, and eliminating security risks.
Description
Technical field
The present invention relates to technical field of buildings, be used in particular for brick, the block structure technical field of construction wall.
Background technology
The domestic construction insulation layer is mainly to be outer thermal insulation construction method at present, and interior heat insulating construction method is auxilliary, and two kinds of job practicess have weak point.The external insulation method economy is relatively good, but fireproof performance is relatively poor, wind resistance is taken off and the weatherability deficiency, the building insulating layer Acceptable life is shorter, and thermal capacitance material extreme difference (polyphenyl foam plate and polyphenyl extrusion molding foam-board) particularly is though the every performance of thermosets is relatively good, but be unable to bear the temptation of economic interests, use inferior materials and turn out substandard goods, add the lack of standardization of construction, so the popularization of the construction of external wall outer insulation is restricted.
Some external developed regions way is: build double-deck body of wall earlier, fill hard polyurethane foams again in the middle of two-layer body of wall, masonry high insulating effect, but cost height only are applicable to middle small sized multiple story building, and this method is unsuitable for most building.
Existing EPS composite thermal self-insulation building block, adopt EPS to be clamped between the two-layer building block, owing to do not have the attachment function of self between EPS and the building block, be fixed as one so need fixed forms such as making dovetail groove or gauze wire cloth between the bonding surface of EPS and building block reach, nonetheless, still easy split, to making the production building block and using all inconveniences, in addition, EPS is in the easily fusion of back of being heated, cause body of wall to cave in, form the very big potential safety hazard of external wall system.
Summary of the invention
The object of the invention is to propose a kind of convenient produce, build, save cost, bridge cut-off composite self-insulation masonry that fireproof performance is good, safe.
The present invention includes block body, offer some through holes in the short transverse of described body, it is characterized in that: offer the polyurethane foam hole parallel with described through hole direction at the middle part of described body, the degree of depth in described polyurethane foam hole is identical with the height of described body, the length in polyurethane foam hole is less than the length of described body, and the two ends of polyurethane foam hole length direction are provided with distance with the two ends of body length direction respectively; In described polyurethane foam hole, the hard polyurethane foams layer is set.
The present invention adopts polyurethane foam to be made in the middle of the block body, it has the caking property fabulous with block body, the tearing strength of polyurethane foam and block body is greater than 0.1MPa, even if also can not separate with block body by high temperature, production, construction have been made things convenient for, also be beneficial to the globality intensity that improves external wall system, no potential safety hazard.
During construction, after with concrete mortar polyurethane bridge cut-off composite self-insulation masonry of the present invention being built into, the body office position of adopting cleaver or other instrument will be positioned at polyurethane foam length direction two ends immediately knocks out respectively, the block body of polyurethane foam both sides is disconnected fully, reach separation, eliminate cold bridge phenomenon, to reach the excellent insulating effect, not only be incubated but also prevent fires, facade is done and is decorated or by the conventional method dry wall outside this body of wall again, wall heat-insulation system cost of manufacture is significantly reduced, and heat insulation effect does not reliably have cold bridge phenomenon.
In addition, polyurethane foam of the present invention hole also is provided with tongue and groove on the width of body, can strengthen the contact area of polyurethane foam laminar surface and body surface, further improves the adhesion strength of polyurethane foam and block body.
For the ease of remembering the other position that will knock out, the present invention also arranges respectively in two outsides of the body corresponding with two ends, described polyurethane foam hole and knocks out the mark wire casing.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 knocks out the diagram that forms behind the body part after the present invention is built in construction.
The specific embodiment
As shown in Figure 1, the present invention includes block body 1, offer some through holes 2 in the short transverse of body 1, offer the polyurethane foam hole 3 parallel with through hole 2 directions at the middle part of body 1.
The degree of depth in polyurethane foam hole 3 is identical with the height of body 1, the length in polyurethane foam hole 3 is less than the length of body 1, the two ends of polyurethane foam hole 3 length directions are provided with apart from 3-1 with the two ends of body 1 length direction respectively, and polyurethane foam hole 3 also is provided with tongue and groove 3-2 on the width of body 1.
Arrange respectively in two outsides of the body 1 corresponding with 3 two ends, polyurethane foam hole and to knock out mark wire casing 1-1.
In polyurethane foam hole 3, adopt to inject polyurethane foam liquid then the mode of foaming enrich hard polyurethane foams layer 4 arranged.
As shown in Figure 2, in work progress, 1 innings of position of body of adopting cleaver or other instrument will be positioned at two outer ends of length direction of hard polyurethane foams layer 4 knocks out the figure that the back forms, and as seen, has reached by polyurethane foam 4 and forms complete bridge cut-off.
Claims (3)
1. bridge cut-off composite self-insulation masonry, comprise block body, offer some through holes in the short transverse of described body, it is characterized in that: offer the polyurethane foam hole parallel with described through hole direction at the middle part of described body, the degree of depth in described polyurethane foam hole is identical with the height of described body, the length in polyurethane foam hole is less than the length of described body, and the two ends of polyurethane foam hole length direction are provided with distance with the two ends of body length direction respectively; In described polyurethane foam hole, the hard polyurethane foams layer is set.
