Gap coordinates, and gap is 5～10mm.
In aforementioned structure, described latch is reinforced concrete precast member or steel beam column.
Due to employing technique scheme, the present invention compared with prior art, adopt by Reinforced Concrete Cantilever Beams of the present invention
With prefabrication system, and still belong to pioneering with the attachment structure of main body concrete in building field by latch.Safety is more common
Joint bar is more guaranteed.Present invention eliminates reserved joint bar in prior art hitch, reduce construction investment, simultaneously also without
Later stage pours hitch concrete again, simplifies working procedure, main body concrete thus can continuous rapid increase.The present invention is using pre-
The latch staying requires come the interior anchoring to meet precast beam, overcomes original concrete cantilever beam due to construction period and is difficult to synchronization
The shortcoming being poured in main body concrete, and reserved joint bar carry out the beams of concrete later stage when pouring hitch be difficult to fill closely knit
Shortcoming.
Brief description
Fig. 1 is the structural representation of the present invention.
Being labeled as in accompanying drawing：1- precast beam, 2- main body concrete, 3- hitch, 4- body pin, 5- beam pin-and-hole, 6- stop
Dynamic pin, 7- rod-like articles.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples, but not as any to the present invention
Limit.
A kind of Reinforced Concrete Cantilever Beams of the present invention and the method for attachment of main body concrete, as shown in figure 1, the method
Reinforced Concrete Cantilever Beams adopt precast beam 1, adopt inserting mode between precast beam 1 and main body concrete 2, and through latch 6
Anchor and position.In prefabricated reinforced concrete cantilever beam, reserve beam pin-and-hole 5 in precast beam 1 one end.Pouring main body concrete 2
When, pre-reserved beam sump 3 on main body concrete 2, and reserve body pin 4, the position of body pin 4 and beam in the bottom surface of hitch 3
The position of pin-and-hole 5 corresponds to.The depth of beam pin-and-hole 5 is slightly larger than latch 6 length；The depth of body pin 4 is latch 6 length
Half.Between precast beam 1 and hitch 3, and between latch 6 and beam pin-and-hole 5 and body pin 4, it is gap cooperation, gap
For 5～10mm.When precast beam 1 is connected with main body concrete 2, by crane gear, the beam pin-and-hole 5 of precast beam 1 is sling downwards,
Hitch 3 on the end alignment main body concrete 2 of precast beam 1；Then by latch 6 put into beam pin-and-hole 5 and with rod-like articles 7 to
Upper top pressure latch 6；Hitch 3 is inserted in precast beam 1 end, release arm after latch 6 enters hitch mouth with precast beam 1
Shape object 7；Continue for precast beam 1 to push hitch 3, after precast beam 1 reaches precalculated position, latch 6 bottom is moved fully to
Above body pin 4, under Gravitative Loads, latch 6 automatically falls into body pin 4, by precast beam 1 anchor and position.If cantilever beam
When load that top is born is relatively large, also precast beam 1 and horizontal plane can be formed certain minute angle（Beam far-end is slightly above
Anchored end）, to further enhance the bearing capacity of this prefabricated cantilever beam.
A kind of Reinforced Concrete Cantilever Beams of the present invention constituting as stated above and the attachment structure of main body concrete, such as
Shown in Fig. 1, this attachment structure includes main body concrete 2 and Reinforced Concrete Cantilever Beams；Reinforced Concrete Cantilever Beams are precast beam
1, the bottom surface of precast beam 1 one end is provided with beam pin-and-hole 5；The side of main body concrete 2 is provided with hitch 3, and the bottom surface of hitch 3 is provided with main body
Pin-and-hole 4, is provided with latch 6 in body pin 4 and beam pin-and-hole 5.The position of body pin 4 is corresponding with the position of beam pin-and-hole 5；Beam pin
The depth in hole 5 is slightly larger than latch 6 length；The depth of body pin 4 is the half of latch 6 length.Precast beam 1 and hitch 3
Between, and between latch 6 and beam pin-and-hole 5 and body pin 4, it is gap cooperation, gap is 5～10mm.Latch 6 is
Reinforced concrete precast member or steel beam column.
Embodiment
As shown in figure 1, having drawn the diverse location of three precast beams in Fig. 1, the A beam in Fig. 1 is shape when being not inserted into hitch 3
State figure；B beam in Fig. 1 is state diagram when being inserted into hitch 3, is direction of insertion, in insertion process shown in the arrow of in figure
Middle use rod-like articles 7 top pressure latch 6 upwards, prevent latch 6 during insertion from beam pin-and-hole out；C beam in Fig. 1
It is state diagram during fully-inserted hitch 3.When being embodied as, main body concrete 2 pre-reserved beam sump 3 in casting process, exist simultaneously
Body pin 4 is reserved in hitch bottom, and main body concrete can continue to rise afterwards.Armored concrete precast beam may be selected other any
Place carries out prefabricated.Reserve beam pin-and-hole 5 in the anchored end correct position of beam, in beam pin-and-hole 5, place latch 6（According to cantilever beam
The load being undertaken, latch 6 can adopt reinforced concrete structure, and steel construction may also be employed）.Precast beam can be by when installing
Girder construction（Band latch）In overall feeding hitch 3, latch（Bottom certain length）Can automatically fall in hitch reserved
In body pin 4, to realize automatically locking and to anchor function.The structure of this example does not need reserved joint bar it is not required that the later stage pours
Build hitch concrete, simplify the working procedure of cantilevered beams of concrete, also further ensure construction quality simultaneously, and first
Precast construction is applied to Reinforced Concrete Cantilever Beams.The present invention is applied to all cantilever beam structures.
The present invention cannot be only used for cantilever beam, if hitch being made U-shaped or increasing the height of hitch it can also be used to beam two
End and the connection of main body concrete.Due to being non-rigid attachment structure between central sill of the present invention and main body concrete, and in beam
Leaving certain interval and main body concrete between, so having certain wider space when being subject to and expanding with heat and contract with cold, will not produce interior
Stress.Also there is certain cushion space it is not easy to crack when vibrated.When pouring main body concrete, do not result in and apply
Work is disturbed, it is possible to increase the pouring quality of main body concrete.Its structure is made more to tend to reasonable.There is certain antihunt action.
