Abstract
The utility model provides a light and high-strength wood or bamboo base laminar composite precast slab, which is characterized in that a three-layer or a five-layer structure is adopted, wherein the three-layer structure adopts the scheme that the surface layer and the bottom layer adopt wood or sawn timber or veneer laminar material or bamboo laminar material, the interlayer or the core layer adopts common wood or sawn timber or medium density fiberboard or veneer laminar material or original shaving lumber, and the interlayer or the core layer is horizontally laid or vertically intersects with the surface layer and the bottom layer; and the five-layer structure adopts a symmetric structure, the surface layer, the bottom layer and the interlayer adopt wood or sawn timber or veneer laminar material or bamboo laminar material, the second layer and the fourth layer adopt common wood or sawn timber or oriented shaving board or medium density fiberboard, and the second layer and the fourth layer are horizontal laid or the second layer vertically intersects with the surface layer and the interlayer and the fourth layer vertically intersects with the interlayer and the bottom layer. The precast slab has the advantages of light weight, high strength, natural reproducibility, powerful carbon adsorption function, environmental protection, strong shock resistance, proper price, convenient transportation and fast and convenient house construction.
Description
Technical field
The utility model relates to a kind of light weight high strength wood or bamboo base laminated composite precast slab, belong to the composite precast slab technical field.
Background technology
In industry and civilian construction (dwelling house, apartment and commercialization), use reinforced concrete (concrete) precast plates (beam) and cast-in-place beams at present in a large number.Reinforcing bar and cement separately in the manufacture process energy consumption big, greenhouse gas emission is extremely serious, and produces a large amount of dust and pollution.Cause environment pollution in the house unloading process once more, and material can not be recycled.Compare with wood structure, steelframe and cement structures use nearly 17% and 16% the energy respectively, and fecund is given birth to 26% and 31% greenhouse gases effect.The fact shows that constructional materials that the house adopted and the current climate change that we face are closely bound up.Generally use timber, wooden construction sheet material and timber i beam in the housing construction of three to four layers in country such as North America or six layers now, large-scale non-residential project begins progressively to promote and adopts timber laminated beam (Glulam), laminated veneer lumber (LVL) and veneer vertically to amass to become a useful person (Parallam or PSL) as main load-supporting part.Research adopts timber cross laminate material (CLT) to do structure such as roof, partition wall and floor and load-supporting part is a kind of inevitable.
Summary of the invention
The utility model proposes a kind of light weight high strength wood or bamboo base laminated composite precast slab or beam, its purpose is intended at the ubiquitous weight of present precast reinforced concrete plate (beam) is big, shock resistance is poor, heat-insulating property is low, installation is inconvenient and pollute big, the high remarkable shortcoming of energy consumption, having proposed based on wood (bamboo) and composite material thereof is the high-strength light made through the lamination reorganization of elementary cell, the NEW TYPE OF COMPOSITE precast plate (beam) of environmental protection, with a large amount of replacement ore fuel densification type products--precast reinforced concrete plate (beam) or cast-in-place plate.Do structure and load-supporting parts such as roof, partition wall and floor with timber cross laminate material (CLT).
Technical solution of the present utility model: light weight high strength wood or bamboo base laminated composite precast slab or beam, it is characterized in that three layers or five layers, three layer construction is that wood or sawn timber or laminated veneer lumber or bamboo material stacked material are top layer and primer, normal wood or sawn timber or oriented wood chipboard or medium density fibreboard or laminated veneer lumber or directed wood shavings are become a useful person and are that intermediate layer or sandwich layer, intermediate layer or sandwich layer are that level laying or intermediate layer or sandwich layer and top layer and bottom intersect vertically; Five-layer structure is balanced configuration, and wood or sawn timber or laminated veneer lumber or bamboo material stacked material are top layer, bottom or intermediate layer, and normal wood or sawn timber or oriented wood chipboard or medium density fibreboard are the second layer and the 4th layer, and the second layer and the 4th layer are that level is laid; Or the second layer and top layer, intermediate layer intersect vertically, and the 4th layer intersects vertically with intermediate layer and bottom.
Advantage of the present utility model: light weight high strength wood or bamboo base laminated composite precast slab or beam high-strength light, can naturally regenerate, be natural heat insulator, powerful carbon adsorption function is arranged; Have environmental protection, shock resistance is strong, price is suitable, convenient transportation, house are built advantages such as quick and convenient; The heat conductivility of structural panel is about 1/9 of precast reinforced concrete plate (beam) and a cast-in-place beam; Being extensive use of in industry and civilian construction can promote thermal insulation property of construction 40% more than, reduces the discharging of greenhouse gases greatly, thereby reaches the resultant effect of energy-saving consumption-reducing.
Description of drawings
Accompanying drawing 2 is three layer construction schematic diagrames that intermediate layer or sandwich layer and top layer and bottom intersect vertically.
Accompanying drawing 3 is that the second layer and the 4th layer are the five-layer structure schematic diagrames that level is laid.
Among the figure 1 is top layer, the 2nd, and bottom, the 3rd, intermediate layer or sandwich layer, the 4th, the second layer, 5 are the 4th layer.
The specific embodiment
The length that is used to replace wood (bamboo) base laminated composite precast slab (beam) of industrial construction precast reinforced concrete plate (beam) or cast-in-place plate is generally 3.0-4.2m (4 feet), width is 1.2m (4 feet), and structure, thickness and breadth can in time be adjusted according to load-bearing requirement and use occasion.Be generally 3 layers, 5 layers even 7 layers.Below be four kinds of typical industrial construction wood (bamboo) base laminated composite precast slabs (beam), used sawn timber can comprise many specifications, but with 2 " * 6 ", 1 " * 6 " and 2 " * 4 ", 1 " * 4 " be main.
Embodiment 6, and light weight high strength wood or bamboo base laminated composite precast slab are top layer and primer by wood (saw) material, and oriented wood chipboard (OSB) or medium density fibreboard (MDF) are made for core material.The sawn timber specification of table bottom is 2 " * 6 ", 35 * 135mm after planing operation, become.Core material thickness after sanding is generally 10-20mm.The thickness of final products then is 80-90mm.
Embodiment 7, and light weight high strength wood or bamboo base laminated composite precast slab all are made up of wood or sawn timber.Its structure is 5 layers, balanced configuration.Top layer, intermediate layer and bottom usually adopt 2 " * 6 " or 1 " * 6 " sawn timber of specification, 35 * 135mm or 15 * 135mm after planing operation, become.Remaining two-layerly then lay with other three layers intersect vertically balanced configuration or level.The specification of sawn timber can adopt 1 usually " * 6 ", 15 * 135mm after planing operation, become.The thickness of final products is 75mm or 135mm.
