Abstract

The invention discloses a single-row three-hole self-heat-insulating and soundproof masonry block wall body, mainly consisting of single-row three-hole self-heat-insulating and soundproof masonry blocks, heat-insulating mortar and anti-cracking mortar. Each single-row three-hole self-heat-insulating and soundproof masonry block consists of a hollow masonry block with three through holes and two thermal bridges in a single row, as well as a heat-insulating material and two heat-insulating key boards arranged in the holes, wherein the heat-insulating material is pre-arranged in the central hole in a factory; two edge holes with opened lateral sides and adjacent masonry blocks respectively form heat-insulating key holes during masonry; the heat-insulating key boards are inserted into the heat-insulating key holes; each of the two heat bridges consists of two symmetric side ribs; and the size of an external convex beam column is not more than one fourth the thickness of each masonry block when the masonry block is used, and all layers are pressed and constructed in a hole alignment manner. The heat-insulating mortar is fully paved and grouted in transverse and vertical seams among the masonry blocks; the compressive strength of the heat-insulating mortar is more than that of the wall body and the value of the compressive strength is converted according to the area of ribs of an actual bearing wall of the masonry blocks. The anti-cracking mortar is used for anti-cracking plastering of external wall surfaces of the masonry blocks and heat-insulating layers of the beam column, and the dry-shrinkage value of the anti-cracking mortar is less than that of the masonry blocks and the heat-insulating layers of the beam column.

Description

Single three hole self-heat conserving sound insulation blockworks

Technical field:

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

Background technology:

30% of the total power consumption of China's building energy consumption account society at present; Along with its building energy consumption 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 breaks through 75%, strives 83%, 88%, catches up with and surpasses the world's advanced levels.The present invention is achieved in that single three hole self-heat conserving sound insulation blockworks mainly are made up of single three hole self-heat conserving sound insulation building blocks, thermal insulation mortar, anticracking grout.Single three hole self-heat conserving sound insulation building blocks are made up of the building-block of two heat bridges of single three through holes and a heat insulating material and the two blocks of insulation key plates that are positioned in the hole; Wherein, centre bore is at the factory presets heat insulating material, two lateral opening insulation keyholes that when building by laying bricks or stones with adjacent block, formed respectively that the outside is open; Insert insulation key plate in the hole; Two heat bridges are made up of the limit rib of two symmetries, and the evagination beam column was not more than 1/4 block thickness when building block was used, and each lamination stubble is built by laying bricks or stones the hole.Thermal insulation mortar building block anyhow the Man Pu of seam place, irritate real, thermal insulation mortar compressive strength is greater than body of wall compressive strength, its value is converted by the actual bearing partition finned surface of building block is long-pending.Anticracking grout is used for the anticracking of building block wall face, beam column insulation layer wipes one's face, and its drying shrinkage value is less than the drying shrinkage value of building block and beam column insulation layer.

Description of drawings:

1 is two parallel edges ribs of building block in the Figure of description, the 2nd, and building block centre bore 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, 190 infilled walls, wall heat transfer coefficient K≤0.7, thermal resistance R＞1.43

Walling unit parameter: specification 390*190*190 wall rib thickness 26mm; In block material float stone concrete, adding additive is adjusted to coefficient of thermal conductivity below 0.42; Compression strength of building block 3.5Mpa, heat insulating material and insulation key plate are selected the polyamine fat plate of coefficient of thermal conductivity≤0.024 for use, and this building block sows anyhow to grout along building block with the M10 thermal insulation mortar and builds; Exterior wall 20mm anticracking grout is wiped one's face, the common plastering mortar of interior wall 20mm.The theoretical thermal resistance value of this building block and body of wall is 2.24 (over dry) measured value R=2.016 (moisture content and the influence of mortar slit), and this value is high by 33% than wall heat resistance design load 1.43, and its body of wall fractional energy savings is higher than 75%.
