The concrete staircase of building.
The utility model patent is achieved through the following technical solutions:
A kind of precast concrete stair production mould, including stair bottom plate, the stair tread formwork being detachably connected
And end head formwork；The stair tread formwork includes the loading end and step surface of L-shaped connection, and the loading end is placed in work
On face, the step surface is stood in the side of loading end, which can increase the strength and stability of entire mold；The stair
Bottom plate is stood on the loading end of step surface opposite side, and the end head formwork is connected in loading end, step surface and stair bottom plate
The both ends of template form the cavity for pouring precast concrete stair of open top, in use, concrete is directly filled from open-mouth
Enter and since mold lies low, so it is not in various quality flaws that its overall perfusion is relatively uniform, open portion is uniform
Multiple hold-open catches are provided with, this is the intensity in order to increase oral area, and expansion causes oral area to deform after preventing concrete from pouring into.Institute
It states step surface and is equipped with anti-skidding groove face for pouring out tread plate, this is safety in order to increase final products and practical
Property, avoid later-stage secondary from processing tread plate.
The technical solution that the utility model further limits are as follows:
Further, the outside of stair bottom plate and stair tread formwork is equipped with reinforcing rib, and the structure for increasing side is strong
Degree.
Further, the reinforcing rib is twice in symmetrical up and down.
Further, the hold-open catch is that bayonet lock may be reversed, and one end of the bayonet lock is rotatablely connected stair tread formwork
Upper surface, the bayonet lock the other end cooperation stair end template upper surface bayonet lock key seat formation is locked, this be in order to
Ensure its ease for use while increasing entire mould machine intensity.
Further, when pouring, the inner wall of stair bottom plate, stair tread formwork and end head formwork precoats demoulding
Oxidant layer, this is in order to which later period mold can smoothly be taken off.
Further, it when pouring, is pre-loaded into the cavity that stair bottom plate, stair tread formwork and end head formwork surround
Stair steel reinforcement cage, this is to increase and pour the mechanical strength for obtaining stair.
Further, the stair bottom plate is fixedly connected with loading end by row's fixing bolt, the end mould
Plate by bolt be detachably connected on loading end, step surface and stair bottom plate both ends, surround pouring for an open top
The cavity of precast concrete stair is built, this is disassembly, installation and the transport of entire mold for convenience.
It is easy to connect the utility model has the following beneficial effects: the utility model structure is simple, sturdy and durable, it will not be because of
The operation of labor service worker is horizontal different and causes security risk, is worth promoting.
