Description
Technical Field
The utility model belongs to the building engineering field especially relates to a structure of prefabricated stair.
Background
The prefabricated staircase has higher standardized modulization degree and better economy, and is more applied to fabricated buildings. However, with the increase of the application range of the prefabricated staircase, the size and the weight of the prefabricated staircase are increased in some residential buildings and public building projects, the cost of the manufactured mold and the cost of the constructed equipment are increased greatly, and the problem of the standardization of the staircase is solved and the corresponding manufacturing cost is reduced.
SUMMERY OF THE UTILITY MODEL
For solving the technical problem, the utility model provides a can assemble prefabricated staircase based on it is standardized, its modulus combination that has optimized the stair flight under the condition of same span, through the mode of modulus combination to the weight of single stair has been reduced, and the modularization component is made to prefabricated stair flight, improves economic benefits.
The technical scheme is as follows: an assembled prefabricated staircase based on standardization is characterized in that a plurality of modular prefabricated staircases are spliced in parallel to form an integral staircase, a plurality of stepping treads of the prefabricated staircases are provided with inwards-concave reserved grooves, side openings of the reserved grooves are opposite to the openings of the reserved grooves on the stepping treads of the adjacent prefabricated staircases, and the prefabricated staircases are spliced into a complete groove; the reinforcing steel plate covers the groove bottom of the groove, one end of the reinforcing steel plate is fixed at the groove bottom of the left-side preformed groove, and the other end of the reinforcing steel plate is fixed at the groove bottom of the right-side preformed groove; and post-cast concrete is filled and leveled in the groove.
Based on the technical characteristics: the preformed groove is arranged at intervals of one step.
Based on the technical characteristics: and fixing the reinforcing steel plate at the bottom of the reserved groove by using a reserved bolt.
The utility model has the advantages that: the weight of the stairs is reduced, and the construction lifting appliance is economical, so that the construction cost is saved. The stairs can be made into modular components and spliced to form various applicable widths. The mould can be repeatedly used, and the economical efficiency is improved.

Detailed Description
The following describes the present invention in further detail with reference to the accompanying drawings. These embodiments are provided only for illustrating the present invention and are not intended to limit the present invention.
In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.
As shown in figures 1 to 3, a modular prefabricated staircase based on standardization is formed by splicing a plurality of modular prefabricated staircases 1 in parallel to form an integral staircase, wherein the modular prefabricated staircases are modular components formed by the same step height, step width and step height of each prefabricated staircase. After the prefabricated ladders 1 are spliced in parallel, the stairways with various widths taking the width A of a single prefabricated ladder section as a multiple can be spliced according to actual engineering requirements.
The specific splicing method comprises the following steps: the method comprises the following steps that a plurality of stepping treads of prefabricated bench sections 1 are provided with inwards-concave reserved grooves 2, the side edges of the reserved grooves 2 are opened, the openings of the reserved grooves 2 on the stepping treads of adjacent prefabricated bench sections 1 are opposite, and the two openings are oppositely spliced into a complete groove 3; namely, the groove 3 is formed by two preformed grooves 2 and two on two sides. The reinforcing steel plate 4 covers the bottom of the groove 3, one end of the reinforcing steel plate is fixed at the bottom of the reserved groove 2 on one side, and the other end of the reinforcing steel plate is fixed at the bottom of the reserved groove 2 on the other side; and post-cast concrete 6 is filled and leveled in the groove 3.
The setting position of the preformed groove is not limited and can be determined according to the requirements of structural design. It is preferable that the pregrooves 2 are spaced one step apart as shown in fig. 1.
As shown in fig. 3, the reinforcing steel plate 4 may be fixed to the bottom of the preformed groove 2 by using the preformed bolt 5. Of course, it can also be fixed by other methods, such as welding steel plates.
The stair prepared hole 7 and the stair hoisting buried part 8 shown in fig. 1 and 2 belong to the prior art, and the illustration is only a schematic.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
