Description
Technical field
The utility model belongs to the building template class, relates to architectural template structure and improves technical field.
Technical background
In the civil engineering of construction work, during pouring concrete in-situ member (column, crossbeam, shear wall, plane, arc beam, circular arc shell end face etc.), previous a large amount of wooden templates that adopt.In the epoch of " with steel for wood ", the steel template is about to withdraw from the historical stage of building popular after 20 years.Nearest 2 years, get steel template generation then be multilayer (being generally 11 layers) woodwork plate and bamboo offset plate, especially at present general extensively a large amount of wooden template of using, this is falling back of a kind of history, particularly to the abundant China of the forest reserves, the moisture regain of the wooden template of this use undoubtedly and China's " environmental protection, energy-conservation " policy run counter to.Apply raw material be easy to get, cheap, proportion is little, in light weight, demolding performace good, long service life, light and handy, convenient, fast, the safe engineering plastics construction formwork of construction are a kind of trends of history." to mould Dai Gang, to mould Dai Mu " is to carry out " preserve the ecological environment, protect forest resources " this fundamental state policy conscientiously, and the offspring's that benefits the nation and the people, benefits future generations a strong behave is a revolution on building circle, is historical progress, is developing direction.
Summary of the invention
The technical problems to be solved in the utility model is as how moulding Dai Gang, the engineering plastics construction formwork that to mould Dai Mu, provide that a kind of reasonable in design, production technology are feasible, its rigidity and intensity can satisfy civil engineering requirement in the construction work.
This project plastic building template is made of panel, backboard, support and reinforcing rib.Panel and backboard are by supporting vertical the connection, and the panel inboard is a reinforcing rib between support, and the appropriate location on support and backboard is provided with some grooves, so that with fastener regular worker engineering plastics construction formwork.Backboard has two kinds, and a kind of is backboard and two back cords that support the composition primary load bearing, and another kind is backboard and two stiffening girders that support the secondary loads of composition.Backboard depends on the circumstances for the relative position and the parallelism (or gradient) of panel.The supported amount n of every engineering plastics construction formwork is equal to or greater than 4, must be by the one or more back cord of forming by two supports and backboard, and reinforcing rib is not essential, i.e. N 〉=0.Above-mentioned engineering plastics construction formwork is turned over turnback K time by AA ' or BB ' for axis, or K (K=1,2,3,4 of unidirectional in the horizontal direction or two-way successively parallelism splicing ... natural number) can obtain the engineering plastics construction formwork series of all size.Also can be with the engineering plastics construction formwork at its symmetrical center line place, arbitrarily angled to panel one side or toward back plate one side doubling, can form the external corner engineering plastics construction formwork or the inner corner trim engineering plastics construction formwork of various angles.Bend to the circular arc that radius is R to panel one side or backboard one side, can form the circular arc engineering plastics construction formwork of various radius of curvature R.The engineering plastics construction formwork is in transverse plane splicing or when vertically splicing, and only needs stupefied on the limit of adjacent two engineering plastics building blocks (back cord at the edge) groove with screw rod or fastener is fixed gets final product.
The utility model engineering plastics building form removal performance is good, can improve the quality and the finish of building member; Splicing installing/dismounting between the template is convenient, safety, saving of work and time, increase work efficiency; Template proportion is little, in light weight, and transportation, lifting, carrying, construction lightly can reduce labor intensity; The template long service life, cheap recyclable again utilization again.

The specific embodiment
With Fig. 2 is example, and the engineering plastics construction formwork elementary cell among Fig. 2 is with shown in Figure 1, and the basic size of its elementary cell is as follows:
The distance L of AA '-BB '
1=100 millimeters
Back cord height H=50 millimeter, width b=35 millimeter;
Stiffening girder height h=25 millimeter, width B=65 millimeter
Support number n=5
Reinforcing rib N=0
Be turned into parallelism number of times K=8 (wherein once to the distortion of 15 millimeters of right translations with once to 50 millimeters distortion of left) with above-mentioned engineering plastics construction formwork elementary cell.
In sum, L as shown in Figure 2 be 900mm * 50mm engineering plastics construction formwork cross-section structure as can be seen: it is to be integral by 9 elementary unit groups, is extruded into section bar by integral body, and the length of section bar can artificially be set arbitrarily.In actual applications, can cut out arbitrarily in the vertical as required and be cut into suitable length, settle at one go, need not to resemble polylith splicing at the scene multilayer woodwork plate or the steel form, saving of work and time.Can cut out in the horizontal and be cut into the width that conforms to all size that modulus (generally being mould with 50mm) requires (this example can cut out be cut into width be respectively 50,100,150,200,250,300,350,400,450,500,550,600,650,700,750,800,850,900 totally 14 kinds of specification width) the engineering plastics construction formwork of matched moulds and the engineering plastics construction formwork of 8 kinds of non-Mould Breadth degree (35,135,235,335,435,535,635,735), and the horizontally-spliced big plane of forming any width of the template of all size.Obviously, it more can satisfy the column of rectangular cross section of all size and the instructions for use of crossbeam.
In actual use the of the present utility model, splicing of its transverse plane or vertical splicing are by bolt or reinforce the limit of adjacent two Plastic-steel form boards with fastener stupefied (it is stupefied that the back cord of every template outermost both sides is called the limit, it is stupefied that the middle arbitrary back cord of template all might become the limit) promptly accuse and finish, during form removal bolt or fastener taken off and get final product, very convenient, safety, saving of work and time, reduce labor intensity, shorten the engineering time.
