The quality and performance of object are built, guides the better sustainable development of real estate, the industrialization of architectural engineering has been industry development
Trend.Industrialization engineering outstanding feature is exactly fabricated construction, and how to improve the globality of assembled architecture, reduces component
The difficulty of processing, installation improves the quality of component installation, shortens set-up time etc., becomes the master for influencing industrialization engineering development
Want factor.
Traditional cast-in-situ stair, must be by processes such as formwork, reinforcing bar binding, concretings, on labour and duration
It adversely affects.And the problems such as Construction defect of cast-in-situ stair is more, is easy to appear the mould that rises, spillage, concrete is reaching
Personnel walk up and down before to intensity, easily damage to corner angle of marking time, and traditional stair construction there are construction efficiency low, time
Length, cost is big, environmental pollution is more serious, quality and performance are poor, material utilization amount is big, effect on environment is big, precast stair connection
There are absolute altitudes to adjust the problems such as inaccurate at place, and using precast stair connecting node is to solve the problems, such as this compared with effective measures.
Utility model content
The purpose of this utility model is to provide a kind of precast stair connecting nodes, so that prefabricated bench and prefabricated terraced beam connect
What is connect is more stable, and mounting means is simple, convenient for construction, to improve construction efficiency.
In order to achieve the above object, the major technique solution of the utility model is to provide a kind of precast stair connecting node,
For the connection of prefabricated bench and prefabricated terraced beam, the prefabricated terraced beam is equipped with pre-embedded bolt, and the prefabricated bench is equipped with bench
Preformed hole, the bench preformed hole are uniformly distributed on peripheries with hole edge reinforcing rib, and the bench preformed hole of the prefabricated bench is set in pre-
On the pre-embedded bolt for making terraced beam.
Further, the top of the prefabricated bench is equipped with bench groove, and the center line and bench of the bench groove are pre-
The center line boxed out is overlapped.
Further, the length of the pre-embedded bolt is greater than the depth of bench preformed hole, and the length of the pre-embedded bolt is small
In the sum of the depth of bench preformed hole and bench groove, the upper end of the pre-embedded bolt is connected with whole fastening plates, the entirety
Fastening plates are located in bench groove.
Further, microlith grouting material is filled in the bench preformed hole.
Further, be additionally provided with bolt solid anchor solid plate in the prefabricated terraced beam, the bolt solid anchor solid plate with it is pre-buried
It is bolted.
The beneficial effects of the utility model are:
(1) pre-embedded bolt in the prefabricated terraced beam of the utility model, and pre-embedded bolt is arranged in bolt solid anchor solid plate, have
Effect strengthens the globality of pre-embedded bolt, connects the precast stair good integrity that prefabricated bench is formed with this；
(2) the utility model adds hole edge reinforcing rib around prefabricated bench preformed hole, and it is pre- to greatly strengthen prefabricated bench
It boxes out the globality on side, effectively preventing reserved hole-edge stress concentration leads to the damage of prefabricated bench.
