Description
Technical field
The invention belongs to precast stair technical fields, and in particular to a kind of concrete prefabricated stairs of accurate positioning.
Background technology
Now normal stair construction, usually assembling reinforcement after the supporting module of scene, casting concrete are continuous to water
Maintenance 14 days, just can make concrete reach strength criterion, then manually pick chisel to stairwell surface again and do hair, then row pastes ceramic tile dress
Guardrail, whole process are taken a lot of work arduously, and sewage dust noise is serious, and stair are integrated with building, and shock resistance is bad, earthquake
When levels floor generate vibrations can be applied directly on stair, cause stair fracture, collapse so that destroying.
The concept of precast stair was proposed in recent years：Stair are pre-formed in factory's dental lamina and formwork, it is existing to construction
It is directly installed after, is not needed supporting module, also do not need water seasoning, save water resource and curing time, greatly
It shortens the construction period.But this precast stair is more demanding for lifting operation, and pre-buried reinforcing bar is difficult to penetrate precast stair both ends
In reinforcing bar location hole, installation is not convenient enough, flexible.
Invention content
To solve the above problems, the invention discloses a kind of concrete prefabricated stairs of accurate positioning, installation is quick and convenient,
Accurate positioning can keep higher shock resistance again after installation.
In order to achieve the above objectives, technical scheme is as follows：
A kind of concrete prefabricated stairs of accurate positioning, including precast stair ontology, precast stair ontology are equipped with and mark time,
It marks time and is topmost equipped with link block with bottom in precast stair ontology, it is pre- that the link block upper surface is equipped at least two installations
It boxes out, the installation preformed hole is kidney slot, and arc convex is equipped with below link block, and positive stop strip is equipped on the outside of link block, described
Protrusion is vertical with positive stop strip antarafacial.
As an improvement of the present invention, described surface a side of marking time is along equipped with railing preformed hole.
As an improvement of the present invention, the precast stair body interior is equipped with lifting hole(eyelet), the lifting hole(eyelet) direction and protrusion
Direction is consistent.
As an improvement of the present invention, the quantity of the lifting hole(eyelet) is three, is separately positioned on the upper of precast stair ontology
Side, intermediate, lower section.
As an improvement of the present invention, the protrusion is semi-cylindrical hill.
As an improvement of the present invention, it is equipped with buffer layer below the link block.
As an improvement of the present invention, upper semisection is arranged on the outside of link block in the positive stop strip.
The beneficial effects of the invention are as follows：
A kind of concrete prefabricated stairs of accurate positioning of the present invention are quickly positioned using arc convex, and positioning is accurate
Really, it is inserted into reserved steel bar in the installation preformed hole of kidney-shaped, it is quick and convenient, since precast stair is as an individual accessory,
It is not involved in overall structure stress, higher shock resistance can be kept, it is ensured that smooth, the increase safety of escape route.

Direction from geometric center of specific component.
As shown, a kind of concrete prefabricated stairs of accurate positioning of the present invention, including precast stair ontology 1,
Precast stair ontology 1 is equipped with and marks time 2, and mark time 2 is equipped with link block 3, the company in 1 the top of precast stair ontology and bottom
3 upper surface of block is connect equipped at least two installation preformed holes 4, the installation preformed hole 4 is kidney slot, and 3 lower section of link block is equipped with arc
Shape protrusion 5, link block outside are equipped with positive stop strip 6, and described raised 5 is vertical with 6 antarafacial of positive stop strip.
A kind of concrete prefabricated stairs of accurate positioning of the present invention are internally provided with lifting hole(eyelet) in precast stair ontology 1
8,8 interpolation steel pipe of lifting hole(eyelet) when installation, suspension hook catches on steel pipe both ends and hangs at the both ends of precast stair on building ladder beam, terraced beam
On have with the corresponding groove of protrusion, quickly positioned using arc convex 5, positive stop strip 6 is limited in ten word directions, accurate positioning,
Reserved steel bar is inserted into the installation preformed hole 4 of kidney-shaped, it is quick and convenient, since precast stair is as an individual accessory, do not join
With overall structure stress, higher shock resistance can be kept, it is ensured that smooth, the increase safety of escape route.
The present invention, along railing preformed hole 7 is equipped with, is easily installed railing in described 2 surface a sides of marking time.
8 direction of lifting hole(eyelet) of the present invention is consistent with raised 5 directions.
The quantity of lifting hole(eyelet) 8 of the present invention is three, is separately positioned on the top of precast stair ontology, intermediate, lower section, just
In lifting.
Of the present invention raised 5 be semi-cylindrical hill, convenient for sliding into the groove on terraced beam, is quickly positioned.
The present invention is equipped with buffer layer 9 below the link block 3, absorbs vibrations, reduces impact force.
Positive stop strip 6 of the present invention is arranged in 3 outside upper semisection of link block.
The technical means disclosed in the embodiments of the present invention is not limited only to the technological means disclosed in the above embodiment, further includes
By the above technical characteristic arbitrarily the formed technical solution of combination.
