Abstract
The utility model discloses the connection structures of a kind of precast beam and prefabricated post, the precast beam including vertically arranged prefabricated post and being laterally arranged, rectangular channel is laid on the side on the prefabricated post top, rectangular channel extends perpendicularly to prefabricated post, rectangular teeth is laid on the end face of the precast beam, each rectangular teeth one-to-one correspondence protrudes into each rectangular channel, and inbuilt reinforcing bar is corresponded and fixed in pre-buried reinforcing bar and prefabricated post in precast beam.Rectangular teeth on the precast beam of the utility model protrudes into the rectangular channel opened up in prefabricated post, the occlusion of the two can bear the weight of precast beam without additional structure, and, because of the presence of rectangular teeth and rectangular channel, so that the intensity of the junction between precast beam and prefabricated post is higher, design strength is easily reached, construction period is shorter.New-old concrete joint surface is not likely to produce crack.
Description
Technical field
The utility model relates to the connection structures of a kind of precast beam and prefabricated post more particularly to a kind of by precast beam and prefabricated
The splicing construction that column is stitched together, belongs to assembled architecture field.
Background technique
Prefabricated assembled concrete structure, usually by some other Accessory Members such as prefabricated column, beam, plate and precast stair
Composition.Compared with foreign countries, the PC structure type and engineering method in China are started late, and PC rate is lower.Restrict what PC structure was promoted
Key factor is how to guarantee effective node connection type, how by suitable connection type make PC structure closest to
Cast-in-place concrete structure makes PC structure can guarantee that necessary bearing capacity, energy dissipation capacity are the important topics of current structure design.
Precast concrete, English: precast concrete, thus claim PC component, refer in the factory by standardization,
The concrete product of mechanized manner processing.Corresponding tradition cast-in-place concrete needs building-site molding, shows
Field casting and scene maintenance.Precast concrete is widely used in the fields such as building, traffic, water conservancy, plays the part of in national economy
Drill important role.
Compared with cast-in-place concrete, the precast concrete of the factorial production has many advantages:
Safety: for construction worker, metastable working environment is safely than complicated site operation in factory
Number is higher；
Quality: the quality and technique of building element can be controlled preferably by mechanization production；
Speed: the standardization of preform sizes and characteristic can dramatically speed up installation speed and architectural engineering progress；
Cost: compared with conventional on-site molding, the mold in factory can be used with repetitive cycling, and overall cost is lower；Machine
The demand that tool metaplasia is produced to artificial is less, with the continuous raising of cost of labor, the prefabricated component cost advantage meeting of large-scale production
It is further obvious.
Environment: it is significantly reduced using the construction site field operation amount of prefabricated component, dust pollution, noise pollution are significantly dropped
It is low.
Connection between precast beam in the prior art and prefabricated post is such realization, the side wall on present prefabricated post top
On be fixed with an angle steel, a side wall of angle steel is bonded with the side wall of prefabricated post, and another side wall of angle steel holds up precast beam
End, then the reinforcing bar in precast beam and prefabricated post is fixed together, finally pours concrete, this connection type
Advantage is that steel using amount saves at node, saves template, stress performance is good.But rear pouring concrete quality requirement height, need contact waiting
The concrete at place reaches design strength rear Liftable prefabricated board, causes long construction period.Since new-old concrete joint surface is easy
Crack is generated, therefore connection stiffness is poor.
Utility model content
The purpose of the utility model is to provide the connection structures of a kind of precast beam and prefabricated post, to solve prior art central sill
The rear pouring concrete quality requirement of column junction is high, long construction period.The problem of new-old concrete joint surface is also easy to produce crack.
In order to achieve the goal above, the utility model adopts the following technical solution:
A kind of connection structure of precast beam and prefabricated post, the precast beam including vertically arranged prefabricated post and being laterally arranged,
Rectangular channel is laid on the side on the prefabricated post top, rectangular channel extends perpendicularly to prefabricated post, and described is prefabricated
It is laid with rectangular teeth on the end face of beam, each rectangular teeth one-to-one correspondence protrudes into each rectangular channel, pre-buried reinforcing bar and pre- in precast beam
Inbuilt reinforcing bar, which corresponds, in column processed fixes.
There is gap between the end face of the rectangular teeth and the slot bottom of rectangular channel, be provided with concrete in the gap.
Gap between the end face of the rectangular teeth and the slot bottom of rectangular channel is 30-50cm.
Inbuilt reinforcing bar one-to-one correspondence is welded and fixed in pre-buried reinforcing bar and prefabricated post in the precast beam.
Rectangular teeth on the precast beam of the utility model protrudes into the rectangular channel opened up in prefabricated post, and the occlusion of the two can be with
Bear precast beam weight without additional structure, also, because rectangular teeth and rectangular channel presence so that precast beam and
The intensity of junction between prefabricated post is higher, easily reaches design strength, and construction period is shorter.New-old concrete joint surface is not
It is also easy to produce crack.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
A kind of embodiment of the connection structure of precast beam and prefabricated post, in Fig. 1, prefabricated post 1 is on the basis of being fixed on, to be
It is vertically arranged, the top of prefabricated post 1 is provided with precast beam 2, precast beam 2 is laterally arranged, the both ends difference of precast beam 2
It is supported and fixed in prefabricated post 1, rectangular channel 3 is laid on the side on 1 top of prefabricated post, the extending direction of rectangular channel 3 is vertical
In prefabricated post 1, rectangular teeth 4 is laid on the end face of precast beam 2, each one-to-one correspondence of rectangular teeth 4 protrudes into each rectangular channel 3, in advance
Inbuilt reinforcing bar, which corresponds, in beam 2 processed and prefabricated post 1 fixes, and the reinforcing bar of the two is to be fixed together by welding.
There is gap between the end face of rectangular teeth 4 and the slot bottom of rectangular channel 3, the slot bottom of the end face of rectangular teeth and rectangular channel it
Between gap be 30cm.Concrete is provided in the gap.
Gap between the end face of rectangular teeth in above-described embodiment and the slot bottom of rectangular channel is 30cm, in other embodiments
In, according to the model of reinforcing bar, the gap between the end face of rectangular teeth and the slot bottom of rectangular channel can select between 30-50cm.
Above-described embodiment is the detailed description according to Figure of description to the progress of the embodiment of present patent application, at other
Skill in embodiment, if do not need the technical characteristic bring technical effect in dependent claims, in dependent claims
Art feature can also be not provided with.
