Abstract

The utility model relates to a composite template belonging to the manufacturing field of concrete cast-in-site templates. The utility model is characterized in that a composite core plate made of magnesium oxychloride concrete is welded with a forward arranged steel perimeter frame, the longitudinal and cross sections of which are both in an F shape. A steel longitudinal bar with a C-shaped cross section (or a 7 shape or a Z shape) is buried in advance at the center of the bottom of the core plate by screws. Multiple transverse bars with 7-shaped longitudinal sections are connected between both sides at the bottom of the longitudinal bar and the perimeter frame. The number of the transverse bars can be decided as required. The top of the perimeter frame is also buried in advance in the core plate by screws. The utility model has the advantages of easily obtainable resource, flame retardancy, firm connection, convenient on-site repair, etc., and has exchangeability with general steel templates. The template surface isolated from the concrete does not need demoulding agent and has convenience for cleaning.

Description

Composite formwork

A kind of composite shuttering belongs to the manufacture technology field of cast-in-situ concrete construction formwork.

In the Cast-in-place concrete engineering, introduced in recent years and developed a kind of Steel-wood forming board, its transversal Fig. 1 that meets personally.The 1st, be contained in the blockboard in " E " shape steel week frame 2, it links by screw 3 and all frames 2, cross section be "

" the vertical muscle 4 of steel of shape contacts with it in blockboard 1 bottom center, between the both sides of vertical muscle 4 bottoms and all frames 2, be welded with fan cross sections be "

The horizontal bar 5 of shape.It is compared with present widely used steel form, have not yielding, non-corrosive, can be incubated, fixing advantage such as embedded part, though but its timber resources is in short supply, its surperficial coated with resins but still have inflammability, can't repair after surface punching or damage, being connected between its blockboard 1 and all frames 2 is also easily loosening, thereby can't promote.

The purpose of this utility model be to provide a kind of resource be easy to get, safe in utilization, be connected firmly and be convenient to the composite shuttering of field patch.

Of the present utility model being characterised in that: it is that compound core plate 6 and the longitudinal and transverse cross section of material is all the steel week frame 7 that " F " shape and forward place and is halved together with the magnesite concrete with one, cross section be "

" the vertical muscle 8 of steel of shape is connected with giving sunk screw at its bottom centre line place with this central layer 6, be connected between the both sides of vertical muscle 8 bottoms and all frames 7 fan more the longitudinal section be "

" horizontal bar 9 of shape.Wherein, the cross section of vertical muscle 8 also can be "

" or "

" shape.Ask for an interview Fig. 2-4.

Use proof: the utility model has reached its intended purposes.

In order in conjunction with the embodiments the utility model to be done detailed description below, now as follows employed accompanying drawing title of the utility model application documents and numbering brief introduction:

Fig. 1: the cross-sectional view of Steel-wood forming board;

Fig. 2: the A-A cross-sectional view of composite shuttering;

Fig. 3: the B-B longitudinal section of composite shuttering;

Fig. 4: the bottom view of composite shuttering.

Embodiment:

Ask for an interview Fig. 2～4.Cross section be "

" the vertical muscle 8 of shape links to each other with this central layer 6 with giving the screw that is embedded in these central layer 6 bottom center when compound core plate 6 is made.The longitudinal section be "

" horizontal bar 9 dual-sides and the longitudinal and transverse cross section of the shape all frames 7 and the vertical muscle 8 that are all " F " shape weld mutually.All frames 7 are to make through bending, welding and japanning with steel plate, it links with the mode and the compound core plate 6 that give sunk screw too, the latter's making is earlier magnesia to be mixed stirring by a certain percentage with magnesium chloride solution, add again to be filled in all frames 7 behind the waste wood matter fiber particle and form, can be coated with water-repellent paint on its surface.Among the figure "

" be the weld seam sign.

Use proof: but the resource of this template is easy to get, fire-retardant, the field patch that is connected firmly, it has interchangeability with the steel form of current trend, and plate face rigidity is big, and its plate face and concrete can be isolated, can be without release agent with the minimizing cleaning work.

Claims (3)
