Abstract
The utility model discloses broken bridge composite self-insulation brickwork, and relates to the technical field of building, in particular to the technical field of brick and building block structures for building walls. A plurality of through holes are formed in a height direction of a building block body; a polyurethane foam hole parallel to the through holes is formed in the middle of the body; the depth of the polyurethane foam hole is the same as the height of the body; the length of the polyurethane foam hole is less than that of the body; distances are arranged between the two ends of a length direction of the polyurethane foam hole and the two ends of a length direction of the body; and a rigid polyurethane foam layer is arranged in the polyurethane foam hole. The broken bridge composite self-insulation brickwork has extremely good binding property and insulation property, facilitates production and construction, facilitates improving the integrity strength of an external wall system, and has no potential safety hazard.
Description
Technical field
The utility model relates to technical field of buildings, is used in particular for brick, the block structure technical field of construction wall.
Background technology
At present the domestic construction insulation layer mainly take be outer thermal insulation construction method as main, interior heat insulating construction method is auxiliary, two kinds of job practicess have weak point.The external insulation method economy is relatively good, but fireproof performance is 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, although the thermosets properties 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: first builds double-deck body of wall, then fill hard polyurethane foams in the middle of two-layer body of wall, and the masonry high insulating effect, but cost is high, is only applicable to middle small sized multiple story building, and the method is unsuitable for most building.
Existing EPS composite thermal self-insulation building block, adopt EPS to be clamped between two-layer building block, owing to there is no the attachment function of self between EPS and building block, reach and be fixed as one therefore need between the bonding surface of EPS and building block, make the fixed forms such as dovetail groove or gauze wire cloth, nonetheless, or easily split, to making the production building block and using all inconveniences, in addition, EPS easily melts after being heated, cause body of wall to cave in, form the very big potential safety hazard of external wall system.
The utility model content
The utility model purpose 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 utility model comprises block body, offer some through holes on 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 utility model adopts polyurethane foam to be made in the middle of 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 facilitated, also be beneficial to the globality intensity that improves external wall system, without potential safety hazard.
During construction, after with concrete mortar, the utility model polyurethane bridge cut-off composite self-insulation masonry being built into, the body office position that adopts immediately cleaver or other instrument will be positioned at polyurethane foam length direction two ends knocks out respectively, the block body of polyurethane foam both sides is disconnected fully, reach separation, eliminate cold bridge phenomenon, to reach good heat insulation effect, not only be incubated but also prevent fires, outside this body of wall, facade is done and is decorated or by the conventional method dry wall again, wall heat-insulation system cost of manufacture is significantly reduced, and heat insulation effect is reliably without cold bridge phenomenon.
In addition, polyurethane foam described in the utility model hole also is provided with tongue and groove on the width of body, can strengthen the contact area of polyurethane foam 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 utility model also arranges respectively and knocks out the mark wire casing in two outsides of the body corresponding with two ends, described polyurethane foam hole.
The accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 knocks out the diagram that the body part forms afterwards after the utility model is built in construction.
The specific embodiment
As shown in Figure 1, the utility model comprises block body 1, offers some through holes 2 on the short transverse of body 1, offers 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 and knock out mark wire casing 1-1 in two outsides of the body 1 corresponding with 3 two ends, polyurethane foam hole.
In polyurethane foam hole 3 interior employing inject polyurethane foam liquid then the mode of foaming enrich hard polyurethane foams layer 4 arranged.
As shown in Figure 2, in work progress, the 1 innings of position of body that adopts cleaver or other instrument will be positioned at two outer ends of length direction of hard polyurethane foams layer 4 knocks out the figure of rear formation, visible, has reached by polyurethane foam 4 and has formed complete bridge cut-off.
Claims (3)
