Abstract
The invention particularly relates to a reinforced concrete frame column load converter which is used for the seismic isolation reinforcement of existing buildings and solves the problem that the construction of conventional seismic isolators takes a great deal of time and labor and severely disturbs frame columns. The reinforced concrete frame column load converter comprises two supporting steel columns which are distributed from the top down, moreover, each supporting steel column comprises a square steel pipe and a supporting plate fixed in the square steel pipe, connecting plates are fixed at both ends of each supporting steel column, stiffening plates distributed at the front and the back and stiffening plates I distributed at the left and the right are arranged between each of the connecting plates and the supporting steel column fixedly connected with the connecting plate, and a jack is arranged between the two connecting plates of the adjacent ends of the two supporting steel columns. The structure design of the a reinforced concrete frame column load converter is reasonable and reliable, the disturbance of the reinforced concrete frame column load converter on existing frame-structured beam columns is little, the problem that the section of a frame beam column can be weakened and destroyed due to reinforcement is prevented, and mover, the reinforced concrete frame column load converter also has the advantage that the reinforced concrete frame column load converter is safe to construct, convenient to disassemble and assemble and easy to recycle, and can meet future seismic isolation support maintenance and replacement projects.
Description
Technical field
The present invention relates to building engineering construction field, be specially a kind of reinforced concrete frame column load conversion device for existing building base isolation reinforcement.
Background technology
There is earthquake disaster in China many places in recent years, although a lot of existing building is provided fortification against earthquakes, can not meet the requirement of current Chinese code of practice, rebuild if remove, the waste of cost height is large, so after carrying out seismic hardening, reducing energy consumption to these houses, still can continue to use.
Seismic isolation technology is adopted to reinforce building structure, compared with traditional Shockproof reinforcing method, its reinforcing thought changes cost-effective damping, shock insulation into from simple rigidity antidetonation, change into " dredging " from original " firmly anti-", originally seismic energy will be absorbed by building structural element plastic strain, change into and to be completely cut off by Seismic Isolation of Isolation Layer and to absorb seismic energy, reduce earthquake to the destruction of superstructure, reach the object improving building structure aseismatic ability.
General only to the construction of building structure foundation when base isolation is reinforced, not affecting the building function of superstructure and normally use, is a kind of economic and practical Shockproof reinforcing method.
To the method that existing building (frame construction) applies earthquake isolating equipment conventional be at present: the upper joist of bracing or strutting arrangement is fixed on original structure reinforced concrete post by tie plate, thus certain disturbance is had to former concrete column component, and be fabrication and installation again in this process, operating process is wasted time and energy, and affects efficiency of construction.
Summary of the invention
The present invention is wasted time and energy and the problem larger to frame column disturbance to exist when solving the construction of existing earthquake isolating equipment, provides a kind of reinforced concrete frame column load conversion device.
The present invention adopts following technical scheme to realize: reinforced concrete frame column load conversion device, comprise two brace steel posts distributed up and down, and brace steel post is all made up of rectangular steel tube and the gripper shoe be fixed in rectangular steel tube, the two ends of brace steel post are all fixed with junction plate, junction plate and and its fixing brace steel post between be provided with before and after the stiffener I that distributes of the stiffener that distributes and left and right, be provided with jack between two junction plates of the two adjacent sides of brace steel post.
During operation, check the planeness of concrete component and brace steel post contact area, and by finisher by brace steel post and concrete component contact surface surface finish smooth, subsequently superposed brace steel post is connected with reinforced concrete floor and rc-frame-beam, then the brace steel post being positioned at bottom is connected with reinforced concrete foundation bolt, finally jack is arranged between two brace steel posts, thus upper and lower brace steel post is held out against, realize the load conversion treating base isolation reinforcement frame column, exist when overcoming the construction of existing earthquake isolating equipment and waste time and energy and the problem larger to frame column disturbance.
The stiffener quantity of the two adjacent sides of brace steel post is three pieces, and the quantity of stiffener I is two pieces; The stiffener quantity of the two opposing sides of brace steel post is one piece, and the quantity of stiffener I is two pieces.
The optimal design of stiffener and stiffener I quantity, further increases the stability that brace steel post is stressed.
Reasonable in design of the present invention is reliable, very little to the disturbing influence of original frame construction beam column, avoid because reinforcing the frame beam column cross section weakening caused and the problem destroyed, also there is construction safety, easy accessibility simultaneously and be easy to the advantage that reuses, the maintenance that can meet in the future shock isolating pedestal with change engineering.

Detailed description of the invention
Reinforced concrete frame column load conversion device, comprise two brace steel posts 1 distributed up and down, and brace steel post 1 is all made up of rectangular steel tube 2 and the gripper shoe 3 be fixed in rectangular steel tube 2, the two ends of brace steel post 1 are all fixed with junction plate 4, junction plate 4 and and its fixing brace steel post 1 between be provided with before and after the stiffener I6 that distributes of the stiffener 5 that distributes and left and right, be provided with jack 7 between two junction plates 4 of the two adjacent sides of brace steel post 1.
Stiffener 5 quantity of the two adjacent sides of brace steel post 1 is three pieces, and the quantity of stiffener I6 is two pieces; Stiffener 5 quantity of the two opposing sides of brace steel post 1 is one piece, and the quantity of stiffener I6 is two pieces.
In specific implementation process, for the reinforced concrete frame column of shock isolating pedestal to be installed, at the whole Vierendeel girder beam-ends be connected with frame column, this load conversion device is all installed; Adopt between each parts of brace steel post 1 and be welded to connect, the junction plate 4 on superposed brace steel post 1 top is temporarily fixed at this layer of upper ledge by the indented bars bolt of two crab-bolts and four straight thread heads and sets a roof beam in place at the bottom of beam, crab-bolt directly connects at the bottom of top board and original structure Vierendeel girder beam, and indented bars bolt connects top board and original structure floor.
