Description
Technical field
The utility model relates to construction work interior wall cement wall plate, specifically a kind of square cementitious composite Light trabs.
Background technology
The synthetic material of existing cement light wallboard is summed up with installation node way common fault;
1, the Light trabs body of wall is usually in installation, the clay of sheet material top beach is wiped off by the top beam slab substantially, contact point between plate and the beam just becomes the dry joint that different-thickness differs in size, step up to harden with roof beam with timber wedge and close in sheet material bottom, at the bottom dry patching mortar or in solidifying, because timber wedge is soft, produce deflection in various degree, later stage is scraped 1-2mm thickness in decorating in plate and both sides, beam slab junction putty and guipure hide the top layer, the elongated crack that differs in size just occurs and produce not sound insulation phenomenon after the contraction of surface layer putty.
2, non-bearing sheet material body of wall in use passes to Light trabs because the structure beam slab produces sedimentation in various degree and produces the downwarp phenomenon, and arc becomes to cause the sheet material body of wall to produce in various degree at different parts to both sides, makes sheet material deformation of wall or crack.
3, the crack of analysis-by-synthesis Light trabs existence, the subject matter of not sound insulation:
1) the Light trabs shrinkage value of using other cementitious materials such as ordinary Portland cement to produce is bigger, it is oversize to finish ST, about about 1000 days, the real main cause (the elongated shrinkage crack phenomenon that generally occurs behind the 1-2 in the use of precast concrete roof panel just can illustrate this point) that in use occurs the crack for sheet material;
2) mostly be dry joint between sheet material and sheet material and the beam slab, it is narrow to fill mortar for 2 times, local nodes with install unreasonable.
3) panel density is low, and hollow rate is big, and electric hot-water heating cabling strikes pounds junction box to logical and building structure sedimentation and deformation beam slab generation downwarp, makes sheet material produce the arc change and occurs than micro-crack.Main cause for not sound insulation.
The utility model content
The purpose of this utility model be to provide a kind of soundproof effect good, metope flawless square cementitious composite Light trabs in back is installed.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of square cementitious composite Light trabs, it is made of composite concrete shell and its inner cement fly ash foaming body of filling vertical placement, lamellar upper end open, hollow, and the component of foaming body adheres to the surface of internal cavity of composite concrete shell securely; Above the top of cementitious composite Light trabs elongatedness direction, foaming body, be provided with fin.
Be respectively arranged with corresponding boss and groove in the left and right sides of cementitious composite Light trabs; Fin, boss and groove three's axis coplane; The cross section of described fin is triangle, trapezoidal, square or circular arc.
One, the material of the utility model composite lightweight wall plate (calling sheet material in the following text) and structure innovation advantage:
1, the synthetic cementitious materials of sheet material and material have determined the comprehensive quality and the performance of sheet material, and the utility model combined wall board is respectively that the material by housing and two kinds of difference in functionalitys of kernel is combined as a whole aborning.The cementitious materials that its middle shell adopted is fast hard micro-expansion cement, aggregate, river sand, stone flour, Admixture etc., socketing material is glass fiber net, steel wire etc., its maximum characteristics: the sheet material housing that utilizes this cement to manufacture can be finished lifelong intensity and shrinkage value by high-temperature steam curing in 48 hours, and this is to guarantee that sheet material is not in use because of the key measure of shrinkage crack.(be different from ordinary Portland cement and other cementitious matter, can only finish intensity and shrinkage value about 94% at 28 days, remaining intensity and shrinkage value are finished with about 1000 days approximately, the later stage crack phenomenon that brings thus).Its casing rigidity height, density is big, and soundproof effect is good, and accommodative ability of environment is strong, and its performance is identical with concrete, not only can be used for indoorly also can being widely used in outdoor and pasting various surface layers, directly swabbing and brush Da Bai.
2, the sheet material kernel is filled and to be utilized flyash, stone flour and cement to synthesize the ultralight foamed heat insulating concrete slurry of making and housing is disposable aborning is combined as a whole, both reach kernel sound-absorbing, sound insulation, insulation, ageing-resistant new function, improved Light trabs standard for sound insulation and insulation standard under construction again.
After testing, its shrinkage value only is≤0.2mm/m (standard 0.8mm/m); The thick sound insulation of soundproof effect 90mm reaches 45dB; Thermal transmittance has reached 0.92W/m
2K; Fracture resistence force: 〉=1000N; Impact resistance: 3 no through cracks, hang 〉=800N, density 65kg/m
2, combustibility: do not fire; All meet or exceed existing standard.And can arbitrarily adjust according to the needs that use and increase thickness and intensity.
The utility model composite lightweight wall plate is gone through the test in 4 years, obtains desirable result of use in practicality, and the production technology and the product of its innovation belong to domestic initiation.
Emerging of the utility model composite lightweight wall plate will produce huge comprehensive social benefit, sheet material advantage: in light weight, it is 1/3rd of existing wall weight, reduce construction costs 5%, increase usable floor area, floor space is little, and speed of application is fast, convenient, flexible, and increased the heat preservation and soundproof function newly.
Two, the utility model composite lightweight wall plate new node advantage
1, end section intermediate triangle projection 20mm (seeing shown in Figure 1) on the board, can contact with the beam slab small size tightly, the condition that provides that installs and fixes is provided, after installing, sheet material projection both sides breach adopts low-intensity micro-expansion cement mortar to fill up at twice and tamps, soft timber wedge changed the precast concrete skewback into during installed the bottom, solved the sheet material bottom produces sinkage and appearance in tamping mortar dry joint straight joint phenomenon.
2, produce under the condition of downwarp in load and little distortion when the building structure beam slab, the triangle bossing on sheet material top and low-intensity filled with mortar material, can consume distortion downwarp phenomenon in the bossing plate of sheet material top in the foaming body and low-intensity mortar, produce the crack phenomenon that arc in various degree becomes and brings thus to both sides after solving sheet material body of wall pressurized.
3, in order further to improve sound insulation and to reduce the crack, sheet material body of wall electric pipeline, socket switch pre-buried, reserve and be operated in the production and processing pre-buriedly in advance according to conventional criteria, strike in stopping to install and pound the crack phenomenon that causes and junction box to by to logical phenomenon.
The utility model combined wall board is after conscientious comprehensive summing up, comprehensive improvement and raising have all been done from top layer material and internal construction set aside pre-embedded to node and job practices, fundamentally changed the material-structure node, made the functional performance of Light trabs and scope that great raising and breakthrough arranged.
