Description

Light-duty bench board of assembled prefabricated stair

Technical Field

The utility model belongs to the technical field of the construction technology and specifically relates to a light-duty bench board of prefabricated staircase of assembled.

Background

The traditional prefabricated staircase is usually an assembled staircase formed by combining a prefabricated tread plate and a prefabricated beam or a straight-running solid plate type staircase. The former has light dead weight, but is inconvenient to install and has poor integrity; the latter is self-weight, the template universality is poor, and the cost is high. The newly adopted through-long-hole hollow stair set by a pipe drawing method has the advantages of reduced self weight, complex manufacture and reduced stress performance caused by the need of end sealing at the joint of the prefabricated stair and cast-in-place concrete. In order to reduce the dead weight of the stair sections, facilitate construction and hoisting and ensure the integral performance of the stair, the invention provides the assembled prefabricated stair light stair section plate, which has the advantages of light dead weight, convenience in production, convenience in hoisting and the like, and the application advantages of the prefabricated stair are fully exerted.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, a light-duty bench ladder of assembled prefabricated staircase board includes a plurality of stirrup 1 and a plurality of straight reinforcing bar 2, still includes:

the fixing devices 3 are used for fixing the straight steel bars 2 in the stirrups 1;

two hanging nails 4 arranged on the straight steel bars 2;

and the two ends of the fillers 5 are open and communicated, and the fillers 5 are placed on the straight steel bars 2 and are abutted against the stirrups 1 or the fixing devices 3. In the utility model, a plurality of straight steel bars 2 are fixed in a plurality of stirrups 1 through a plurality of fixing devices 3, hanging nails 4 are fixed on the straight steel bars 2, the fixed straight steel bars 2 and the stirrups 1 are placed in a mould, after fillers 5 are placed on the straight steel bars 2, concrete is poured into the mould, iron plates are used for smoothing and press polishing, after the hardness of concrete reaches the standard, the mould is disassembled, and a lifting rope on a crane is matched with the hanging nails 4 so as to transport a formed ladder section plate away; the filler 5 is used for replacing concrete, so that the weight of the whole ladder section plate can be reduced, and the cost is reduced; the die is spliced by five plates, and the spliced die is provided with a placing cavity; the two ends of the filler 5 are sealed by asbestos cement.

As a preferred embodiment of the present invention, it may also have the following additional technical features:

in this embodiment, fixing device 3 includes montant 31, two are curved first support piece 32, a plurality of horizontal pole 33, a plurality of is curved second support piece 34, a plurality of retaining member 35 and a plurality of fender piece 36, first support piece 32 sets up in montant 31 one end, first support piece 32 and second support piece 34 are connected to horizontal pole 33, retaining member 35 rotationally sets up on first support piece 32, keep off the piece 36 setting and fix stirrup 1 in first support piece 32 both sides, during the use, straight reinforcing bar 2 passes first support piece 32, rotate retaining member 35, retaining member 35 one end and straight reinforcing bar 2 butt, and then fix straight reinforcing bar 2 at first support piece 32, pass second support piece 34 with other straight reinforcing bar 2 again, can realize the quick fixed to stirrup 1 and straight reinforcing bar 2.
