Face combines and is specifically illustrating, and the utility model is further described.
Referring to Fig. 1, the bracing means of frame structure node region, the Vierendeel girder 100 including being parallel to ground surface, Vierendeel girder
100 surface is vertically installed with frame column 110, and Vierendeel girder 100 and 110 central intersection point of frame column are set as node, Vierendeel girder
100 and the vertical connection area of frame column 110 be set as stabilization zone 120, the back of Vierendeel girder 100 and the column root of frame column 110
Place is provided with the firmware pasted by structure glue, and the surface of firmware is socketed with the molding band steel fixing piece of pre-production,
Band steel fixed frame includes the L-shaped band steel 130 of rectangular structure, and the socket side of L-shaped band steel 130 is welded with a side opening
The closed square shape band steel 140 in three sides, the bar shaped steel side of 140 aperture side of square shape band steel band steel fixing piece and Vierendeel girder 100,
The socket of frame column 110 is completed to complete to fix by site welding mode, being provided at the axle center of 140 side of square shape band steel
Learn anchor bolt 150.
It includes to be engaged on the horizontal ends on 100 surface of Vierendeel girder and be engaged on frame column 110 that L-shaped band steel 130, which is socketed side,
The vertical end on surface, the length of horizontal ends are greater than the length of vertical end, and firmware uses steel plate or carbon cloth.
Referring to fig. 2, in one embodiment of the utility model: when being reinforced to frame beam-ends top surface hogging moment area,
Typically occur in small earthquake situations shape design；
The square shape band steel quantity that horizontal ends are socketed in Vierendeel girder surface is four, and vertical end is socketed in frame column surface
Square shape band steel quantity is two.
In top surface of the beam: L-shaped band steel not only works together with the steel plate for the back that needs reinforcement or carbon cloth, supplements steel using amount, but also
Play the role of fixation steel plate or carbon cloth together with square shape band steel chemical anchor bolts simultaneously.
On column surface: the steel plate or carbon cloth for pasting top surface of the beam are the requirement for meeting anchorage length, it is necessary to it climbs upwards along column,
Play the role of fixation steel plate or carbon cloth together with square shape band steel chemical anchor bolts in column Surface L font band steel at this time.
Square shape band steel had not only played the shearing resistance effect of silent stirrup, but also reduced the quantity of chemical anchor bolts, was particularly conducive to
At vertical muscle and the intensive beam-ends of stirrup and column root.Meanwhile it and being completely fixed the steel plate of corner or carbon cloth, having avoided herein
The persistent ailment that steel plate or carbon cloth are not fixed easily.
Referring to Fig. 3, Fig. 4, in two embodiments of the utility model: to frame beam-ends top surface, root column, joint reinforcing
When, typically occur in small earthquake situations shape design；

A, the square shape band steel quantity that vertical end is socketed in frame column surface is five.
It only needs to increase square shape band steel according to actual state, principle is identical.
Referring to Fig. 5, in three embodiments of the utility model: in typically occurring in, big earthquake situations shape design:
When the utility model is local tension and compression sinker, the L-shaped band steel uses the low surrender with energy consumption property
Intensity steel, L-shaped band steel use LY100 or LY160 or LY225, L-shaped band steel antisymmetry cloth above and below Vierendeel girder axle center
It sets.
If L-shaped band steel is changed into low yield strength steel (such as the LY100/LY160/LY225 with energy consumption property
Etc.), and antisymmetry is arranged above and below top surface of the beam bottom surface, then can form local tension and compression sinker, is formed truly
Beam-ends plastic hinge (horizontal repeatedly displacement with micro- rotation), guarantee node region to a certain extent in small shake, the even big shake of middle shake
Under can enter surrender energy consumption state, comprehensive rigidity, the bearing capacity, ductility and energy consumption for improving bean column node, tool stage by stage
Have surrender opportunity controllable, it is replaceable after shake the advantages that.
In short, the utility model keeps frame structure key position stress more reasonable, it can be according to the reinforcing of different parts
Need to select corresponding combined bay form.By the innovation optimization design, it can accomplish large-scale production, more convenient, function is installed

In worry, big earthquake situations shape design when, the utility model be also in Current Building ' earthquake resistant code anti-seismic performance target design important
Old building (such as Grade A hospital, museum, historical protective buildings) reconstruction with reinforce one of concrete application and promote,
Reference frame can be provided with modification for following specification upgrading.
The utility model mentality of designing is clear, it is only necessary to flat accordingly according to reinforcing position Vierendeel girder and frame column production
Steel fixing piece, this can directly complete the process in factory, only connect in construction area and be socketed in stabilization zone, then straight to need mouth
Reinforcing can be completed in the bar shaped steel side site welding completion of font band steel, and sets in square shape band steel and Vierendeel girder, frame column
Chemical anchor bolts are equipped with, it is strong to consolidate performance.
The beneficial effects of the utility model are: shape model determine, can be needed according to different functions (according to it is small shake,
Middle shake or greatly three kinds of design circumstances dictates of shake) selected combining form, scale blanking production, effect diversification fixing steel
While plate or carbon cloth, itself extraly participates in the common reinforcement of steel plate or carbon cloth again, particularly the consumption of building structure
Energy supporting form, is shifted to miniaturization, supplements and enrich energy consumption form series, and guidance market producer develops energy consumption steel
The new product of material, practical performance is excellent, is a kind of good innovation scheme, is very promising for marketing..
