Loading capability.The overall performance of bracket improves, and can effectively improve the overall performance of shear wall bottom joist.
Through the above scheme, in-site installation is carried out using the good bracket of pre-production and shock isolating pedestal 2, avoids tradition
Cast in situs the problem of bringing, shock-insulation rubber cushion 21 is connect with cylinder and is converted into upper pre-embedded steel slab 3 and upper junction steel plate 22
Connection, improves the precision of connection, while steel plate processing consistency is good, is especially suitable for industrial mass production.The type branch
Seat structure is simple, convenient for standardized designs, batch production batch production, assembled in situization construction, while can solve shock insulation
The job site problems such as 21 deviations of rubber pad, spillage pollution shock-insulation rubber cushion 21, to effectively solve to deposit in the prior art
The problem of.
As advanced optimizing for scheme, upper stud 1 further includes several lateral stressed stirrups 42 and several longitudinal stress steel
Muscle 41, lateral stressed stirrup 42 form hog frame 4 built in frame-type with Reinforcement 41, and built-in 4 part of hog frame is exposed
In the top of upper stud 1.Built-in hog frame 4 can increase the intensity of stud 1, carries out shear wall bottom joist in upper stud 1 and applies
Good connection structure is provided when work, is conducive to the connection of cast-in-place concrete Yu upper stud 1, exposed parts can enhance cast-in-place
The connection of concrete and upper stud 1 guarantees the structural stability after the completion of integral construction.
In the present embodiment, cross groove 12 is equipped at the top of upper stud 1,12 surrounding of cross groove forms four column tenons
11.Cross groove 12 and column tenon 11 can increase the contact area of stud 1 Yu shear wall bottom joist, improve connection effect,
Improve structural stability.Joinery and its construction can effectively improve the bonding strength of two connecting components, than directly carrying out coagulation on the whole
Soil has poured apparent connection effect and has been promoted, while cross groove 12 increases the exposed reinforcing bar part of built-in hog frame 4,
Be exactly shear wall bottom joist and bracket apokoinou construction more, connection effect between the two is obviously improved.All cross
It is not turned off at cross groove 12 to stress stirrup 42 and Reinforcement 41, arrangement of reinforcement can guarantee node in upper stud 1
Core space resistance to compression and shear-carrying capacity have preferable deposit.
As advanced optimizing for scheme, built-in hog frame 4 includes column tenon hog frame 43 and cross hog frame 44, column tenon
Hog frame 43 is set in column tenon 11, and cross hog frame 44 is set in cross groove 12.Cross hog frame 44 surrounds cross
12 periphery of connected in star is arranged, for enhancing and the bonding strength of shear wall bottom joist.It is directed to column tenon 11 and is provided with column
Tenon hog frame 43 realizes that upper stud 1 is held in the palm with shear wall bottom using cross hog frame 44 for enhancing 11 body structures of column tenon
The shared part of beam carries out reinforcement connection, guarantees that bonding strength between the two is sufficiently strong.
As advanced optimizing for scheme, upper stud 1 is cuboid, and the top surface of upper stud 1 is square；Column tenon 11 is length
The top surface of cube, column tenon 11 is square.The cylinder symmetry that cross section is square is strong, and force stability is strong, prefabrication process
The stress of middle generation is small.Using the upper stud 1 and column tenon 11 of symmetrical structure, when stress, the transmitting of power and the production of stress
It is raw uniform, it effectively prevent defect caused by local stress to generate.Symmetrical structure simultaneously, during concreting is molding
The stress of itself is few, and coagulation result is good.
As advanced optimizing for scheme, the size of 11 top surface of column tenon is the 1/3 of the size of upper 1 top surface of stud.Column tenon 11
With the equivalent width of cross groove 12, guarantee the constitutional balance of the two.It is closed by the size of control column tenon 11 and upper stud 1
System, so that integrally-built symmetry further strengthens, overall structure is balanced, and is guaranteeing that it is enough that cross groove 12 has
Connection area is used for while further pouring connection of shear wall bottom joist, guarantees that 11 size of column tenon will not be too small, guarantees
It is not easily damaged during the installation process.
In the present embodiment, the top surface of column tenon is equipped with medial surface and cross groove top surface and 12 top surface of cross groove
Rough surface, rough surface are evenly distributed with protrusion and pit.Cast-in-place concrete and pop-up of the rough surface for more shear wall bottom joist
The contact area of column 1, further increases connection effect.This support overall construction can guarantee that node area is equal to cast-in-place concrete section
Point, the computation model and actual conditions for using structure design more coincide, and realize the reliable power transmission of structure.Rough surface can also be protected
Card relies on rough contact surface also and can provide significantly even if gluing with bracket bad after cast-in-place concrete solidification
Connection function.
As advanced optimizing for scheme, protrusion and the depth of pit are more than or equal to 6mm.Too small depth can not accommodate existing
Rubble in pouring concrete, connection effect is not good enough, and increased contact area is not big enough.11 inside of column tenon and top setting are coarse
Face, rough surface and area are not less than the 80% of faying face, and rough surface bumps depth is not less than 6mm.
It in the present embodiment, further include built-in bolt sleeve 5, built-in bolt sleeve 5 is set to upper 3 top surface of pre-embedded steel slab, on
Pre-embedded steel slab 3 be equipped with the first mounting hole, upper junction steel plate 22 be equipped with the second mounting hole, built-in bolt sleeve 5, the first mounting hole and
The center line of second mounting hole three is overlapped.Using the sleeve of built-in type, can be completed when installation at the scene using bolt
The connection of upper stud 1 and shock isolating pedestal 2, without additional equipment such as welding.Using threaded connection, installation essence can be effectively improved
Degree, the quantity and type of equipment and tool that scene needs reduce, and construction site is cleaner and tidier, and construction efficiency is higher.
In summary, the prefabricated assembled shock isolating pedestal 2 that the present invention designs, it is contemplated that the shock design of frame structure is usual
It is position setting shock isolating pedestal 2 corresponding in frame column, internal force is transmitted with point-to-point simple form.The shock insulation of shear wall structure
Design is then to need to carry out Structure Calculation according to internal force transitive relation of the relative complex line to point.Realize this mentality of designing
Major section is exactly to pass through setting support wall conversion beam at the bottom of the shear wall, the beam often while bearing superstructure vertical force,
The significant horizontal power generated under geological process and wind action, the beam play a significant role for total.This hair
The groove that bright prefabricated shock isolating pedestal 2 is arranged can guarantee that the joist to cross forms cast-in-place region in support node core space, indulge
Can also be kept in groove continuously to steel bar stress 41, after the completion of floor and joist concrete cast in situs, joist with it is prefabricated
Shock isolating pedestal 2 can collective effect, form complete shear wall converting system, realize shear wall structure shock insulation.
