Popularization is come, and in order to improve whole efficiency of construction, wherein stair also start using fabricated structure, assembly common at present
Connection structure between the formula stair and stair stringer more connection structure of mutual-inserting type mostly, comes then in conjunction with microlith expansive concrete
It is fixed, whole connection effect and intensity are poor.
Summary of the invention
The utility model aim is to provide the connection structure of a kind of precast stair and stair stringer, it can efficiently solve background
The problem of in the presence of technology.
In the presence of solving the problems, such as background technique, it includes precast stair 1 and the stair stringer 2 being mated with；
The top of the stair stringer 2 concaves out a mounting groove 21, and the end of the mounting groove 21 is provided with a gear
Plate 22 is reserved with certain gap at the upper topside of the baffle 22 between the bottom edge of precast stair 1, in the mounting groove 21 with
The end of 22 opposite side of baffle, which extends inwardly pre-buried two, ranked first reinforced steel bar ring 23；
The both ends of the precast stair 1 are respectively arranged with the positioning beam 11 mating with mounting groove 21, the positioning beam 11
One end extend outward the second reinforced steel bar rings 24 that pre-buried two rows are staggered with the first reinforced steel bar ring 23.
It is embedded with the first iron plate 12 at the top plate of the 1 both ends platform of precast stair, it is pre- at the upper top surface of the stair stringer 2
It is embedded with the second iron plate 25.
The both ends of first iron plate 12 or the second iron plate 25 are respectively welded for the hanging ring 3 for lifting.
After the first iron plate 12 is docked with 25 level of the second iron plate, the upper top surface of first iron plate 12 and the second iron plate 25
Place is welded with upper cover plate 4.
Due to using above technical scheme, the utility model has the following beneficial effects: structure is simple, it is easy to use,
The bonding strength between precast stair and stair stringer can effectively be improved.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the partial enlarged view of Fig. 1.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face will combine the attached drawing in the utility model embodiment, carry out to the technical scheme in the embodiment of the utility model clear, complete
Ground description.
Referring to Fig. 1-2, present embodiment, which adopts the following technical solutions, to be achieved, it includes 1 He of precast stair
The stair stringer 2 being mated with；
The top of the stair stringer 2 concaves out a mounting groove 21, and the end of the mounting groove 21 is provided with a gear
Plate 22 is reserved with certain gap at the upper topside of the baffle 22 between the bottom edge of precast stair 1, in the mounting groove 21 with
The end of 22 opposite side of baffle, which extends inwardly pre-buried two, ranked first reinforced steel bar ring 23；
The both ends of the precast stair 1 are respectively arranged with the positioning beam 11 mating with mounting groove 21, the positioning beam 11
One end extend outward the second reinforced steel bar rings 24 that pre-buried two rows are staggered with the first reinforced steel bar ring 23.
It is embedded with the first iron plate 12 at the top plate of the 1 both ends platform of precast stair, it is pre- at the upper top surface of the stair stringer 2
It is embedded with the second iron plate 25.
The both ends of first iron plate 12 or the second iron plate 25 are respectively welded for the hanging ring 3 for lifting.
After the first iron plate 12 is docked with 25 level of the second iron plate, the upper top surface of first iron plate 12 and the second iron plate 25
Place is welded with upper cover plate 4.
The application method and its principle of technical solution part in present embodiment are made with reference to the accompanying drawing further
Elaboration:
When installation, positioning beam 11 is inserted respectively into corresponding mounting groove 21 by hanging device first, due to first
Reinforced steel bar ring 23 is to be arranged in a staggered manner, therefore can very easily be inserted into the second reinforced steel bar ring 24, is also needed to installation before insertion
Actual range between the slot bottom and top surface of slot 21 measures, and ensures that positioning beam 11 is inserted by way of increasing spacer
After in mounting groove 21, the first iron plate 12 and the second iron plate 25 are in same level, then fill microlith expansive concrete
Enter into mounting groove 21, until extra microlith expansive concrete is between the top margin of baffle 22 and the bottom edge of precast stair 1
Gap location overflows, and cuts off hanging ring 3 after microlith expansive concrete solidifies completely, then covers upper cover plate 4 in the first iron
It on plate 12 and the second iron plate 25 and is welded and fixed, greatly improves whole combination and bonding strength.
In this embodiment all technical characteristics and components can by way of market purchasing come into
Row is implemented, and for those skilled in the art, being completely can be according to the technology contents and reality disclosed in present application
It applies what mode was accurately implemented, is a clear, complete technical solution.
