Abstract

The utility model relates to a double-row four-hole self-heat-conserving and sound-insulating building block which consists of hollow building blocks, two heat-conserving materials and two heat-conserving key plates, wherein the hollow building blocks comprise double rows, four through holes and two heat bridges; the two heat-conserving materials and the two heat-conserving key plates are arranged in the holes; the heat-conserving effect and the sound-insulating effect are improved because of the two heat bridges formed by three straight side ribs and two bend side ribs; heat-conserving materials are preplaced in two heat-conserving holes in factories; the heat-conserving key plates are respectively formed when two side holes which are respectively arranged at the two ends of the two rows and are provided with open outer sides are built with an adjacent building block; and the seamless connection with the adjacent building block is formed by solidly pouring mortar into building seams after the heat-conserving key plates are inserted in the holes.

Description

Double four hole self-heat conserving sound insulation building blocks

Technical field:

The present invention relates to building energy conservation, is a kind of seamless self-heat conserving sound insulation of double four holes, two heat bridges building block that need not the secondary insulation.

Background technology:

30% of present China building energy consumption account society total energy consumption; Along with its building energy conservation of fast development of town and country construction will be broken through 50% of the total power consumption of society; And the energy consumption of building enclosure wall accounts for 30% of building total energy consumption; The external-wall external-insulation energy-saving mode of public and civil building 50%, 65% fractional energy savings of generally carrying out has now produced the exterior trim pull-up major accidents such as fire takes place frequently that fall; It will be argued that and research and develop the not only power save mode of instead external wall outer insulation of self-insulation wall material energetically, and should be as the major fields that improve building energy conservation index energy-saving and emission-reduction low-carbon economy.The sandwich heat preservation building block CN2013399266Y that I have authorized; High thermal resistance assembled building blocks CN201343812Y; Primary and secondary walling body of wall CN201649351U; Utility model patents such as heat and sound insulated wall CN201635213U; Though each has something to recommend him but not enough below existing: the one, be separate component as the building block of retaining wall major part; It structurally can not realize seamless link with adjacent block, and the perps mortar is difficult to reach the optimum efficiency to water, vapour, temperature, sound sealing; The 2nd, the heat bridge that does not reach building block thermal transmittance optimum value and promptly influence the principal element of block insulation also can reduce.

Summary of the invention:

The object of the invention one is the materials for wall that a kind of thorough replacement external-wall external-insulation energy-saving mode of exploitation realizes body of wall and same life-span of exterior trim, no disaster hidden-trouble; The 2nd, invent a kind of meet the existing norm of construction in various places and thickness of wall body and can reach energy-conservation limit value only have two heat bridge adjacent block can realize the universal architecture of seamless link; The 3rd, the kind through adjustment building block, heat insulating material and the parameter of relevant heat preservation and soundproof realize the optimum efficiency of building block and wall thermal insulating, sound insulation, and fractional energy savings is broken through 75%, striven 83%, 88%, catches up with and surpasses the world's advanced levels.The present invention is achieved in that building block is double four through-hole structures; Two have increased insulation and soundproof effect by three straight two curved formed two heat bridges of limit rib respectively; Two insulation holes are at the factory presets heat insulating material; Two split the open lateral opening insulation keyhole that when building by laying bricks or stones with adjacent block, formed respectively in the two row two ends and the outside, will build seam by laying bricks or stones behind the insertion insulation key plate in the hole and irritate the real seamless link that forms adjacent block with mortar.

Description of drawings:

Figure of description is double four hole self-heat conserving sound insulation building block combination sketch mapes.1 is two three straight two curved formed two heat bridges of limit rib in the accompanying drawing; The 2nd, block insulation hole and heat insulating material, the 3rd, the lateral opening and insulation key plate of building block.

The specific embodiment:

Building requirements: 65% fractional energy savings, 240 infilled walls, wall heat transfer coefficient K≤0.6, thermal resistance R>=1.67

Double four the dislocation pore structures of walling unit parameter: block structure 390*240*190; Wall rib thickness 27mm adds additive and coefficient of thermal conductivity is adjusted to below 0.42 compression strength of building block 3.5Mpa in block material float stone concrete; Heat insulating material and insulation key plate are selected the polyurethane sheet of coefficient of thermal conductivity≤0.024 for use; This building block sows anyhow to grout along building block with the M10 thermal insulation mortar and builds, and exterior wall 20mm anticracking grout is wiped one's face, and interior wall 20mm ordinary mortar is wiped one's face.The theoretical thermal resistance value of this building block and body of wall is 3.35 (over dry) measured value R=2.85 (moisture content and the influence of mortar slit), and this value wall heat resistance design load 1.67 is high by 68%, and its body of wall fractional energy savings is higher than 75%.

Claims
