In the present embodiment, (such as center) offers gas vent in the horizontal stiffener 12, and the gas vent is excellent
Circular hole is selected but is not limited to, so that gas when welding is discharged.
In the present embodiment, the horizontal stiffener 12 and the edge of a wing of the short girder steel 11 of H-type are preferably but not limited to uniform thickness, institute
It states horizontal stiffener 12 to be in same level with the corresponding edge of a wing of the short girder steel 11 of H-type, reinforcing effect is good and cost is relatively low.
In the present embodiment, the upper and lower ends portion peripheral side of the steel box column 1 is respectively welded for being correspondingly connected with
The auxiliary otic placode 13 of lower steel column 1 offers bolt hole on the auxiliary otic placode 13, the auxiliary ear positioned at 1 upper end of steel box column
Plate 13 is corresponding with the auxiliary otic placode 13 of 1 lower end of steel box column is located to be staggered and respectively close in the corresponding lateral surface of steel box column 1
Center line.Multiple 1 loading and unloading timings of steel column carry out contraposition connection using auxiliary otic placode 13, and assembling speed is fast, construction efficiency
Height saves manpower.
In the present embodiment, the outer cladding protective layer 2 is armored concrete surrounding layer, the armored concrete surrounding layer
2 include reinforcing bar 21 and concrete 22, and cladding range does not include the splicing node area of steel column 1；Certain outer cladding protective layer 2 can also
To be the outer Packet types such as steel-wire-net reinforced concrete surrounding layer, fire proofing tile surrounding layer or fire-proof plate surrounding layer.In practical application, described
The material and thickness of outer cladding protective layer 2 can be designed according to the protection requirements and stress performance of steel column 1, protect outer cladding
Sheath 2 had not only had specific safeguard function, but also can be with the design life having the same of steel column 1.
In the present embodiment, the concrete 22 that the armored concrete surrounding layer 2 uses is normal concrete or high-performance
Concrete.Wherein, the high performance concrete is steel fiber reinforced concrete, Reactive Powder Concrete or Fireproof concrete etc..
In the present embodiment, the reinforcing bar 21 that the armored concrete surrounding layer 2 uses can be configured by construction, need to only be adopted
With minor diameter steel mesh, connection precision is not also required.
Fig. 1 ~ 4 are please referred to, this partly combines the production method of prefabricated assembled column, comprising the following steps:
(1) make steel column 1: in factory, routinely steel construction production method processes steel column 1, and removes the floating rust in surface；
(2) make outer cladding protective layer 2: the outer cladding protective layer 2 is armored concrete surrounding layer, first in steel column 1
Outer surface arrangement steel mesh, then shuttering, casting concrete 22, vibration compacting in the die station of factory, and Quick steam
It is demoulded after maintenance to design strength；In the manufacturing process of outer cladding protective layer 2, for the node bonding pad of prefabricated assembled column
Domain is then not necessarily to carry out the production of surrounding layer, and the steel member of node point connection zone keeps exposed.
In step (1), the short girder steel 11 of H-type on the steel column 1, horizontal stiffener 12, auxiliary otic placode 13 are all in factory
Welding is completed, removes the floating rust of surface of steel plate, but the process for not requiring ball blast or derusting by sandblasting after the production of completion steel column 1 again,
Also without the requirement of stringent derusting grade.
In step (2), the reinforcing bar 21 of steel mesh can be configured by construction, minor diameter steel mesh need to only be used, to even
Precision is connect also not require.
In step (2), improve shear resistance if necessary, then in the outer surface arrangement steel mesh of steel column 1,
Configure shearing-resistant member.
In step (2), the thickness of the outer cladding protective layer 2 can be according to the fire-protection rating of building and the fire resisting of component
The limit is designed.
Certainly, the outer cladding protective layer 2 of step (2) can also use steel-wire-net reinforced concrete surrounding layer, fire proofing tile surrounding layer
Or fire-proof plate surrounding layer etc.；If outer cladding protective layer 2 is steel-wire-net reinforced concrete surrounding layer, first configured in the outer surface of steel column 1
Construct steel wire or arrangement steel wire and shearing-resistant member (whenever necessary), then in the die station of factory shuttering, pour it is mixed
Solidifying soil, vibration compacting, and Quick steam conserve to design strength after demould；If the outer cladding protective layer 2 of step (2) is fire proofing tile
The scene such as surrounding layer or fire-proof plate surrounding layer profile, then configure shearing-resistant member in the outer surface of steel column 1, simply assemble securely in factory
?.
When construction, make the half prefabricated assembled column of combination is transported to construction site and carries out assembly construction, this half group
Close the node connection side between prefabricated assembled column and other prefabricated assembled components (prefabricated assembled column, prefabricated assembled beam)
Formula is identical as traditional steel structure connection method, i.e., using high-strength bolt connection or bolt-weld joint；Any two prefabrication and assembly construction part
It after node connection, then constructs at the scene to the uncoated area 31,32,33 at each connecting node, fills outer cladding protection
Layer 2.
Fig. 1 ~ 4 are please referred to, this partly combines the design method of prefabricated assembled column, comprising the following steps:
(1) according to the protection requirements of steel column 1 (such as fire-protection rating, fire rating demand) and stress performance, outsourcing is selected
The material of protective layer 2 is covered, and determines thickness；
(2) when calculating the Basic Period of Structure, consider the overall stiffness of steel column 1 and 2 compound section of outer cladding protective layer；
(3) under vertical load, wind load and frequently occurred earthquake combination (i.e. design load) effect, consider steel column 1 and outer cladding
The overall stiffness of 2 compound section of protective layer, i.e. contribution of the consideration outer cladding protective layer 2 to prefabricated assembled column stiffness, should ensure that
Outer cladding protective layer 2, should not occur in the compatibility of deformation of outer cladding protective layer 2 and steel column 1 and shearing slip (changing of the relative positions) occurs for steel column 1
Or the case where cracking of outer cladding protective layer 2；
(4) under middle shake and rarely occurred earthquake effect, allow 2 Cracking Failure of outer cladding protective layer, do not consider that outer cladding is protected
The contribution of 2 pairs of prefabricated assembled column stiffness of layer, i.e., only consider the effect of steel column 1.
The above, the only preferred embodiment of the utility model, not do limit in any form to the utility model
System, anyone skilled in the art is in every case without departing from the content of technical solutions of the utility model, according to the utility model
Technical spirit any simple modification, equivalent changes and modifications are made to above embodiments, should all belong to the culvert of the utility model
Lid range.
