Specific embodiment
The utility model embodiment discloses a kind of precast floor slab building, to efficiently solve precast floor slab building aseismicity
Problem that can be weaker.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Refer to Fig. 1, the partial structural diagram of the precast floor slab building that Fig. 1 is provided for the utility model embodiment.
In a kind of specific embodiment, a kind of precast floor slab building is present embodiments provided, precast floor slab building includes branch
Dagger 1, precast floor slab 3 and energy-absorbing section bar 4.Wherein support column 1 can be steel reinforced concrete post, can also be pin or steel column, in order to have
There is service life higher, and reduce manufacturing cost, preferred support column 1 is steel reinforced concrete post herein.Wherein precast floor slab 3, refers to
The floor layer of the steel and concrete structure of advance reverse mould shaping.It should be noted that wherein support column 1 is used to prop up precast floor slab 3
Support, the position of support can be the lateral location of precast floor slab 3, can also be the centre position of precast floor slab 3.
Wherein energy-absorbing section bar 4 is arranged between precast floor slab 3 and support column 1, and support column 1 is by energy-absorbing section bar 4 with to pre-
Floor processed 3 forms support indirectly, i.e., when support column 1 vibrates, can absorb the vibration that support column 1 brings by energy-absorbing section bar 4
Power, is transferred at floor with vibration force, can reduce significantly, to avoid precast floor slab 3 from bearing larger vibration power.Wherein, it is
More preferable protection precast floor slab 3, being provided with the protector 5 being located on the side of precast floor slab 3 on energy-absorbing section bar 4, with
Precast floor slab 3 is protected in vertical direction and horizontal direction.Energy-absorbing section bar 4 can be using the material with certain elasticity
The structure that material is made, such as rubber, it would however also be possible to employ the smaller elastic structure of deformability, such as shell fragment, can also be it certainly
Its material.Wherein in order to strengthen the intensity of energy-absorbing section bar 4, the side of energy-absorbing section bar 4 can be provided with reinforcement gusset 11.
In the present embodiment, when the application precast floor slab is built, when there is earthquake or other reasons cause support column 1 to produce
During raw vibration, now the vibration force of support column 1 is transferred at energy-absorbing section bar 4, and can be transferred to precast floor slab by energy-absorbing section bar 4
3, but when vibration force is transferred to energy-absorbing section bar 4 by support column 1, because the reason for 4 body structures of energy-absorbing section bar, one can be absorbed
Fixed vibrational energy, makes vibration force that precast floor slab 3 is transferred to after reduction, and the vibration force that such precast floor slab 3 bears is smaller, and
And the fixed structure of fixation is now played, because there is certain elastic activity space, to be unlikely to be damaged in vibration.Institute
In precast floor slab building, because employ energy-absorbing section bar 4 supporting indirectly, can be absorbed to the vibration of support column 1,
And then the vibration force that precast floor slab 3 is afforded is reduced, and then integrally-built stability is improved, so the precast floor slab is built
The weak problem of precast floor slab building aseismicity Performance comparision can be efficiently solved.
Further, also including the support member 6 of the rectangular type in cross section；The vertical edge of the steelframe and the support column 1
It is fixedly connected, the horizontal sides upper surface of the steelframe offsets with the lower surface of the energy-absorbing section bar 4.In view of the thickness of support column 1
The limitation of diameter is spent, the position that support is born on precast floor slab 3 has certain limitation, and the support member 6 of perpendicular type is set, energy
It is enough effectively to increase the supporting surface of precast floor slab 3, and then can effectively avoid the side of precast floor slab 3 from bearing excessive torsion
Square, to improve the service life of precast floor slab 3, and support strength.Wherein support member 6 can be that bolt 12 is connected with support column 1,
Can also be by being arranged on the metal embedded part inside support column 1 to be welded and fixed.
Further, also including the connecting screw rod 9 being vertically arranged, the connecting screw rod 9 is sequentially passed through from bottom to up successively
