Description
Technical field
The invention belongs to a kind of steel frame-CLB of Self-resetting construction applications more particularly to Self-resetting filling wall and its preparations
Method.
Background technique
For traditional steel-frame structure, geological process is only resisted by frame itself or wind load is far from enough
's.In order to reduce the horizontal displacement of steel frame, enhancing structure rigidity, steel frame and wall may be combined to form frame with fill-in walls
Structure.The hysteresis loop of frame with fill-in walls structure is full, and energy dissipation capacity is strong, and anti-seismic performance gets a promotion.But current frame
Most of frame-filling wall construction form is steel frame-Concrete Filled wall, and most of type of attachment is steel fastener fitted bolt
Connection.Concrete Filled wall is connected from great with existing frame, the geological process of structure easy to increase, and this frame-is filled out
Filling most of wall construction is destroyed since connector, and the residual deformation after shake is larger, can not be restored.
For recoverable problem after structure shake, researchers propose a kind of runback bit architecture.Runback bit architecture is
Refer to the constraint between loosening configuration, so that structure is returned to original position by prestressing force after geological process.For runback bit architecture
Research has very much, concentrates on Self-resetting frame, Self-resetting shear wall etc..Most of current existing Self-resetting structure type is steel
Tendon concrete structure, from great, prefabricated rear lifting difficulty；And reinforcing bar, concrete are non-renewable resources, are unsatisfactory for sustainable
The requirement of development.
Summary of the invention

The unbonded prestressing tendon duct of several bamboo boards on replacement B laminate is additionally provided in product bamboo wallboard, it is pre- to be equipped with soap-free emulsion polymeization in duct
One end of stress rib, the unbonded prestressing tendon is fixedly connected with steel frame, and the other end is fixedly connected with basic girder steel.
Preferably, the unbonded prestressing tendon that the present invention uses can be prestress wire, prestressing force spiral or pre-
Stress FRP tendons.
Furtherly, steel frame of the invention includes the frame column on basic girder steel and the frame set on frame column upper end
It sets a roof beam in place, one end of the unbonded prestressing tendon is mutually fixed with Vierendeel girder.Preferably, Vierendeel girder is i shaped cross section Vierendeel girder,
It includes web and equipped with the edge of a wing on web, and one end of the unbonded prestressing tendon is mutually fixed with the edge of a wing.
The method that the present invention prepares above-mentioned steel frame-CLB filling wall, includes the following steps:
(1) cross laminate bamboo wallboard is prepared: according to the setting position of unbonded prestressing tendon in cross laminate bamboo wallboard, system
Standby several A laminates and B laminate, and the not cemented bamboo plate on corresponding B laminate, reserve the duct of unbonded prestressing tendon, then
By several A laminates and B laminate, successively staggeredly glued hot pressing, is made cross laminate bamboo wallboard；
(2) it is equipped with steel frame on basic girder steel, and cross laminate bamboo wallboard is embedded in the steel frame, finally respectively will
Unbonded prestressing tendon is fixedly connected on steel frame and basic girder steel, and the steel frame-CLB that Self-resetting is made fills wall.
The utility model has the advantages that compared with prior art, remarkable advantage of the invention are as follows: the filling wall is by by cross laminate bamboo walling
Plate is combined with steel frame, and the relative storey displacement of each layer of several layers steel frame is enabled to tend to the level for uniformly reducing steel frame
Displacement, and antidetonation multiple defence line can be constituted.Secondly, the present invention is using cross laminate bamboo wallboard as obturator, bamboo wallboard quality
Seismic force gently is effectively reduced, and bamboo wood is green material, is conducive to sustainable development.The present invention uses prestressing without bondn
Muscle is attached, and structure is made to have runback bit function after shake, is reduced residual deformation, is improved the anti-seismic performance of structure, can use
In new building or building are reinforced, without additional setting steel fastener, easy construction.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that single layer of the present invention fills wall；
Fig. 2 is the structural schematic diagram of double-layer filling wall of the present invention；
Fig. 3 is the schematic diagram along the direction Figure 1A-A.
Specific embodiment
Further details of the technical solution of the present invention with reference to the accompanying drawing.It should be noted that being described herein
Used in word "front", "rear", "left", "right", "up" and "down" expression, by taking cube as an example, length direction be a left side
