Description

A kind of multifunctional thermal insulation board

Technical field

The invention belongs to building material field, relating to a kind of is the multifunctional thermal insulation board of matrix through strengthening handling with the foamed glass.

Background technology

The modern house building adopts concrete frames at present, frame is cut or brick mix structure.The tradition sequence of construction is concrete frame construction, infilled wall and partition wall construction, plasters and the decorative operation construction.For the building energy conservation that reaches present regulation requires also insulation layer to be set outside floated coat.At present be broadly divided into three kinds of organic class, mineral-type and complex class as the heat insulating material that insulation layer adopted.Organic class heat insulating material is representative with the styrofoam of present use amount maximum in the engineering, be characterized in not fire-resistant, low with cement-bonded intensity, mass defect such as hollowing easily takes place, come off, for guaranteeing that the safety in the engineering use must adopt the numerous and diverse treatment process of multiple tracks, has increased site operation and quality managemant difficulty.For remedying above deficiency, with comprising that glass fiber reticular cloth and polymer cement rubber cement p-poly-phenyl plate carry out preliminary treatment and carry out site operation again after making alleged composite insulation boards earlier.But no matter adopt which kind of processing method, because the character of organic class expanded material own determines it must depend on the agent structure surface, the deck intensity of adhesion strength and formation is low, weatherability is poor, not fire-resistant etc., and problem can not fundamentally be resolved.With expanded pearlite rock beam, rock cotton board and perlite mortar is that the inorganic heat insulation material of representative is compared except that fire resistance makes moderate progress with organic insulation material, because a series of more problems such as self water absorption rate is excessive to have brought again that metope cracking, heat insulation function descend, deck intensity lowly, easy ftractures, hollowing have caused new quality and potential safety hazard.

Meanwhile, because the restriction of constructional materials and construction technology condition at present, with the house is example, it is minimum that the load that people utilize building to produce accounts for the ratio of engineering total load, the required huge construction investment a large portion of construction works agent structure is used to support the weight of framework, body of wall, floor and the roof system of building self, has caused raw material such as concrete material, steel and masonry to waste greatly.Seek a kind of lightweight, high-strength, have good heat insulating ability and weatherability and the constructional materials being convenient to construct becomes the task of top priority of building trade.

Foamed glass belongs to the usual alleged foam glass of people, has good heat-insulating property.Grind the process system that adds behind the blowing agent melt foaming in accordance with regulations with normal silicate glass and progressively be cooled to normal temperature, specification on request carries out cutting processing and gets final product afterwards.Only be used for industries such as electric power, chemical industry as pipe insulation material in the past, and used very fewly at building engineering, interior exterior wall, building flooring, the roofing that particularly is directly used in the house space enclosing structure substitutes body of wall and precast concrete floor beyond example still at present.Foamed glass mechanical property and heat-insulating property are determined by the porosity, can be made into the different porositys by purposes and requirement in the actual production.As everyone knows, glass have do not absorb water, weatherability, coefficient of thermal conductivity that the coefficient of expansion is little, good are little, with portland cement adhesion strength height, can be in outstanding features such as the following uses for a long time of 400 degree.Its theoretical compressive resistance is 2-5Gpa, is about hundred times of engineering concrete compressive resistance commonly used.Tensile strength is 50Mpa, also is far longer than the tensile strength of ordinary concrete.Foamed glass with its making is separate closed pore bubble combination, and space networks trellis structure further improves mechanical properties of materials.Though glass resistance to compression and tensile strength after foaming descend to some extent than glass, handle all-round enough instructions for uses of satisfying as exterior wall, internal partition wall, floor plate and the roof panel of architectural exterior-protecting construction through corresponding reinforcement.

Summary of the invention

For fundamentally solving the defective that the existing building material exists, the present invention proposes a kind of foamed glass that utilizes as matrix material and multifunctional thermal insulation board through strengthening handling.The material that it can be used as space enclosing structure such as construction wall, building roof, building flooring also can be used for underground, ground engineering insulation.

The technical solution adopted in the present invention is: at first being applicable to that the foamed glass that region of interest requires cuts into the matrix of elongated sheet material as multifunctional thermal insulation board according to building axis line, floor height or reservation dimension of opening, also can adopt joining method to make the sheet material that meets above-mentioned requirements.Bury reinforced mesh afterwards in pea gravel concreten or cement mortar handles the back to above-mentioned sheet material and gets final product by the process system maintenance on the two sides.The protective layer thickness of reinforcing bar should be greater than bar diameter; the netting length of burying underground should guarantee anchoring surplus between the certain plate of the staggered reservation in outer four limits of plate; concrete or floated coat reserve corresponding size and do not do in early stage on four limits, so that assemble the anchor connection that overlaps between the laggard andante material between connection or sheet material and the chassis body.Timber intensity, thickness, two sides reinforced mesh intensity and the concrete or the thickness of mortar coverage fibrous root that are used as matrix determine after using the position by calculating and test.Because coarse surface and the portland cement of foamed glass has very high bond strength, this processing procedure realizes quite easily.The process system of stipulating by concrete through the sheet material of above-mentioned processing is carried out maintenance can obtain described multifunctional thermal insulation board.If must further improve the intensity of multifunctional thermal insulation board, can adopt the technology of producing prestressed member that plate two sides reinforcing bar is gone ahead of the rest and carry out pea gravel concreten after the stretch-draw or plaster and handle and maintenance.

The invention has the beneficial effects as follows: compare with the traditional material construction technology, described insulating board can directly replace the infilled wall and the insulation layer of building engineering, is used as space enclosing structures such as building inner, external wall, has increased usable floor area; Can replace present room walling panel, floor and insulation layer as roof panel and floor plate, strengthen between the room and the sound insulation function of floor gap; Outside realizing, also realized between the room and the insulation between the floor in the insulation, when having simplified work progress, accomplished to reduce to greatest extent building energy consumption.Multifunctional thermal insulation board directly connects with beam, post formed by integrally casting or by welding after by the staggered anchoring of reserved steel bar, has strengthened structural stability; Do not use polymer cement mortar in the construction, reduced environment pollution.Because the density of foamed glass insulating board is at every cubic metre below 500 kilograms, the load that engineering itself forms adds the insulation layer structural behavior with traditional framework, infilled wall and compares reduction more than 1/2, beam, column cross-section size as the main body supporting member also can significantly dwindle, the inevitable corresponding minimizing of concrete and rolled steel dosage and based process expense.Construction costs is inevitable when having saved material usage and having reduced working procedure reduces significantly, has outstanding technique effect, good social benefit and economic benefit.

Description of drawings

Insulating board both sides through above-mentioned processing are basic identical, and its planar configuration is seen accompanying drawing, is made up of foamed glass matrix 1, pea gravel concreten or high-strength mortar layer 2, reinforced mesh 3.

Embodiment

Above-mentioned insulating board is used for construction work and main structure body can adopt connecting mode flexibly: can be embedded in the template and Vierendeel girder as space enclosing structure or as internal partition wall, post is built together, also can be at Vierendeel girder, after the post form removal at its external surface by being arranged on beam, net sheet welding in built-in fitting in the post and the plate connects, because the net sheet that plate Central Plains is reserved has been realized interlaced anchoring after assembling is in place, so connection back in place only needs to use the cement mortar of the same numeral that uses when handling with wiping one's face during making insulating board at untreated position in early stage, plate joint both sides or pea gravel concreten is clogged and tamping, carrying out maintenance after floating gets final product.As roofing and flooring, can adopt the connected mode identical with above-mentioned way.After finishing, operation to be assembled and post-processed can carry out normal interior wall face, ground decoration layer construction operation project according to designing requirement.
