Detailed description of the invention
By describing the technology contents of the present invention in detail, being realized purpose and effect, below in conjunction with embodiment also
Accompanying drawing is coordinated to be explained.
The design of most critical of the present invention is: use the composition aluminium alloy stair step of L-type section bar peace profile material
Template, and utilize the first connecting hole on connecting plate and the 3rd connecting hole on connecting portion cooperate realization many
The fast assembling-disassembling of individual aluminium alloy stair tread formwork.
Refer to shown in Fig. 1 to Fig. 4, the aluminium alloy stair tread formwork that the present invention provides, flat including marking time
Plate 1, stand to baffle plate 2 and end-plate 3;
Described one end founding the width being vertically set on flat board 1 of marking time to baffle plate 2, stands to baffle plate 2
There is connecting plate 4 on top to flat board 1 side of marking time is extended, and connecting plate 4 is parallel to flat board 1 of marking time, and connects
First connecting hole 40 of more than two is offered on plate 4;
Described end-plate 3 has two, and two end-plates 3 are divided into the two ends of the length direction of flat board 1 of marking time,
End-plate 3 be perpendicular to mark time flat board 1 and with the flat board 1 of marking time of the same side, stand to baffle plate 2 and connecting plate 4
Broadside connects, and end-plate 3 is L-shaped, and end-plate 3 offers second connecting hole 30 of more than two;
The other end of the width of described flat board 1 of marking time extends end-plate 3 and forms connecting portion 10, described
The 3rd connecting hole 100 of more than two, the first connecting hole 40 and the 3rd connecting hole is offered on connecting portion 10
100 one_to_one corresponding.
In the above-described embodiments, mark time flat board 1, stand to baffle plate 2, end-plate 3 and connecting plate 4 be aluminum close
Gold material.Wherein, mark time flat board 1 and end-plate 3 can use aluminium horizontal profile material to cut to form, stand to
Baffle plate 2 and connecting plate 4 can use aluminium horizontal profile material to cut to form and (now stand to baffle plate 2 and connecting plate 4
For Split type structure) or directly use L-type shape extrusion to form (now to stand to baffle plate 2 and connecting plate 4 one
Body formed).In order to reduce welding job amount and welding deformation, improve overall construction intensity and production efficiency, this
Invention preferably will be stood to baffle plate 2 and connecting plate 4 one-body molded, directly use L-type shape extrusion to form.
In the above-described embodiments, owing to offering first connecting hole 40 of more than two on connecting plate 4, mark time
The other end of the width of flat board 1 extends end-plate 3 and forms connecting portion 10, and connecting portion 10 offers
More than two and the first connecting hole 40 the 3rd connecting hole 100 one to one, therefore by connector such as bolt
By the 3rd connecting hole 100 on the connecting portion 10 of the aluminium alloy stair tread formwork of last layer and the aluminum of next layer
The first connecting hole 40 on the connecting plate 4 of alloy stair tread formwork is connected with each other, it is possible to achieve multiple aluminum close
The fast assembling-disassembling of gold stair tread formwork, as shown in Figure 5.Stand to the height of baffle plate 2 plus marking time flat board 1
Thickness equal to the height of stair step, therefore stand to baffle plate 2 setting according to the requirement for height of stair step
Height dimension and mark time flat board 1 gauge after, the height of stair step is the most stable, Bu Huiyin
It is the first connecting hole 40 and the machining accuracy of the 3rd connecting hole 100, aligning accuracy and position, hole wear problem are sent out
