Abstract
The utility model discloses a double-C-shaped aluminium-wood-plastic composite building template support keel which comprises a metal wrapping frame and a filling material, wherein the metal wrapping frame consists of two C-shaped high-strength light-weight aluminium alloy sections with opening directions which are reversely arranged; two webs are fixedly connected into a whole; the filling material which is adaptive to the shape of the metal wrapping frame fills the cavity of the metal wrapping frame; the filling material is a wood-plastic composite foaming material; the filling material wholly penetrates through or is arranged in the cavity of the metal wrapping frame by sections at intervals. The double-C-shaped aluminium-wood-plastic composite building template support keel has the advantages that the mass is light, the operation is convenient, the construction efficiency is favorably improved, and the labor and material resources are saved in the building construction process; the holding force to nails is increased by a wood-plastic composite foaming core material, and the fixation of a building template is facilitated; the aluminium alloy sections are adopted as the wrapping frame, the strength of the keel is increased and the core material is protected; the keel is adjustable in length, and the installation is flexible; the core material is a recovered material, and the keel is a green and environment-friendly material-saving support keel with wide market prospects.
Description
Technical field
The utility model relates to a kind of support keel of using for construction formwork.
Background technology
In concrete work, the building of construction formwork and support system thereof is built moulding and is had a direct impact concrete, has even determined the quality of construction work.Therefore the effect of the support keel for construction formwork in support system seems particularly important.At present in building operations, use many construction formwork support keels mostly to be shaped steel keel, rough ground, aluminium alloy joist, also have part to use steel rough ground.But not only quality is large for existing shaped steel keel, and construction is wasted time and energy, but also is easily subject to the impact of moisture in environment and produces corrosion; Rough ground, except wasting a large amount of timber, is gone back the problems such as often generation is rotted, distortion; Aluminium alloy joist is that cost is higher, is unfavorable for promoting; Steel rough ground still can not be avoided the corrosion of the rotten and steel of timber well, or needs comparatively complicated anticorrosion treatment technology.
Utility model content
The purpose of this utility model is to provide a kind of double C-type aluminium wood-plastic composite building formwork support keel, and solve existing shuttering supporting keel and exist quality large, perishable distortion, efficiency of construction is low, and waste social resources are unfavorable for the technical problem of environment.
For achieving the above object, the utility model adopts following technical scheme:
A kind of double C-type aluminium wood-plastic composite building formwork support keel, comprise metal bag frame and packing material, described metal bag frame is made up of the contrary C shape high-strength light aluminium alloy extrusions arranging of two opening directions, two webs are connected to one, in the cavity of metal bag frame, be filled with the packing material adapting with the shape of metal bag frame, described packing material is Wood-plastic-foamed composite.
Between described web, weld or be fixedly connected with by the stud with nut.
Whole of described packing material runs through or becomes spacer segment to be arranged in the cavity of metal bag frame.
The surface of described packing material has the nut preformed groove corresponding with the installation site of nut.
Compared with prior art the utlity model has following characteristics and beneficial effect:
Double C-type aluminium alloy structure of the present utility model is as braced structures, stronger intensity and modulus of elasticity is provided, use the core of Wood-plastic-foamed composite as keel, greatly reduce the weight of keel, also have good iron nail curable grip when can improving keel intensity, the double C-type structure in the utility model makes it have two work planes can nail, fix for template, convenient operation more, is conducive to improve efficiency of construction, the reduction of erection time.
The utility model can substitute the flitch keel that use in current building operations completely, and active response country is to mould the policy of Dai Mu; Use aluminium alloys as backing material simultaneously, greatly reduce the loss of steel in building operations; In these keel, Wood-plastic-foamed composite is recyclable material, saves in a large number social resources, advances green building construction, effectively substitutes the flitch using in current building operations, and active response country is about the policy to mould Dai Mu.

The specific embodiment
Embodiment mono-is shown in Figure 1, a kind of double C-type aluminium wood-plastic composite building formwork support keel, comprise metal bag frame 1 and packing material 2, described metal bag frame 1 is made up of the contrary C shape high-strength light aluminium alloy extrusions arranging of two opening directions, two webs 1.1 are connected to one, in the cavity 1.2 of metal bag frame, be filled with the packing material 2 adapting with the shape of metal bag frame, described packing material 2 is Wood-plastic-foamed composite.
Shown in Fig. 1～2, welding between described web 1.1.Whole of described Wood-plastic-foamed composite runs through or becomes spacer segment to be arranged in the cavity 1.2 of metal bag frame.
Embodiment bis-is as shown in Fig. 3～4, different from embodiment mono-, between described web 1.1, is fixedly connected with by the stud 3 with nut 4, and nut preformed groove 2.1 is also left on the surface of the packing material 2 corresponding with the installation site of nut 4.
Described Wood-plastic-foamed composite is by wood materials, plastic material and the additive material that is composited, one or more of the thermoplastics such as such as polyethylene, polypropylene, modified polypropene, polystyrene, polyvinyl chloride, ABS add one or more the mixture in wood powder, powdered rice hulls, powder of straw, waste and old bamboo wooden form powder and other natural fiber class materials, and one or more mixture extrusion moldings of adding the additive such as calcium carbonate, French chalk form.Size of the present utility model can design production according to practical application request.
