Abstract

The utility model discloses a high-efficiency self-heat-insulating building block which comprises a building block with holes; and the high-efficiency self-heat-insulating building block is characterized in that at least a hole of the building block is filled with rigid polyurethane foams. After the high-efficiency self-heat-insulating building block is used for masonry, due to the small heat conductivity coefficients of the rigid polyurethane foams, the heat resistance of the building block is increased, thereby not only improving the heat insulation effect of the building block, but also improving the waterproofness and durableness of the building block, solving the problem that the heat insulation of a common outer wall can be not kept as long as the service lift of a building, and realizing the structure and energy-saving integration of the building.

Description

Efficient heat insulation building block

Technical field:

The utility model relates to constructional materials, specifically a kind of efficient heat insulation building block.

Background technology:

At present in building field; Exterior wall or interior wall adopt building block (also claiming to lay bricks) masonry structure usually; Its wall thermal insulating is energy-conservation, and that to adopt polystyrene thermal insulation plates or fly ash aerated be main is more; Along with the raising that national building energy conservation and security against fire require, its exterior wall polystyrene thermal insulation plate and common aerated blocks are not only wasted resource, consumes energy, contaminated environment, exist insulation, lightweight, heat insulation, sound insulation value deficiency etc. simultaneously; And can't satisfy insulation and the incorporate requirement of building structure, prevent fires and aspect durability, also existing great hidden.

The utility model content:

The purpose of the utility model provides a kind of have insulation, lightweight, heat insulation, sound insulation, fire prevention, durable efficient heat insulation building block.

Its technical scheme is: comprise the building block that has hole.In at least one hole of building block, be filled with hard polyurethane foam.

Molded or just in moulding various have the hole of building block of hole, inject a certain amount of polyurethane and carry out the foamed heat insulating measure, through natural foaming, make cavity whole fill or part filling, make it compound a kind of efficient heat insulation building block that becomes.After building use by laying bricks or stones, the hard polyurethane foam in hole effectively increases the thermal resistance of hollow masonry, reduces the heat consumption through building, improves the heat-insulating property of building-block.Making it performances such as insulation, lightweight, heat insulation, sound insulation, fire prevention, durability improves greatly; Traditional loam brick, aerated blocks and traditional external wall thermal insulation method have been substituted; Not only realize building structure and energy-conservation integrated, and satisfied country's " living energy-conservation 65% ", " public energy-conservation 50% " building energy conservation requirement fully.

Among the figure: the 1st, building block, the 2nd, hard polyurethane foam.

The specific embodiment

Embodiment 1, and with reference to Fig. 1, this building block 1 is for there being the structure in five round holes.In all holes of building block 1, be filled with hard polyurethane foam 2.

Embodiment 2, and with reference to Fig. 2, this building block 1 is for there being the structure in seven round holes.In all holes of building block 1, be filled with hard polyurethane foam 2.

Embodiment 3, and with reference to Fig. 3, this building block 1 is the structure that " T " word shape is formed in two round holes.In all holes of building block 1, be filled with hard polyurethane foam 2.

Embodiment 4, and with reference to Fig. 4, this building block 1 is the structure of two round hole " Z " word shapes.In all holes of building block 1, be filled with hard polyurethane foam 2.

With reference to previous embodiment, as required hole number of the arrangement, size, spread pattern can be set arbitrarily, be filled with polyurethane foam at least one hole, all belong to the protection domain of the utility model.

The utility model both can be in the molded building block that has a hole hard polyurethane foam foaming compound, it is compound also can to carry out the hard polyurethane foam foaming in the time at block forming.

Claims

1. an efficient heat insulation building block comprises the building block that has hole, it is characterized in that: at least one hole of building block, be filled with hard polyurethane foam.
