Abstract
A framed girder equivalent deloading and reinforcing method for a building structure is realized in a manner that supports are arranged on the two sides of two end pillars of a framed girder; two truss girders or solid web girders are simply supported and placed on the supports; a force transmission girder provided with the two ends connected with the truss girders or the solid web girders is propped against the bottom surface of the framed girder; and partial floor load is transmitted to the two truss girders or the solid web girders through the force transmission girder, and is transmitted to a frame column through the supports on the frame column, so as to form a complete force transmission way, namely, the partial load of the framed girder is reduced, and the framed girder is reinforced.
Description
Technical field
The present invention relates to a kind of building structure frame beam equivalence off-load reinforcing method, especially not to Vierendeel girder strengthen, ruggedized construction only gives post with the form of vertical concentrated force with the Load Transfer of being born, original structure is not produced newly-increased moment of flexure, the Vierendeel girder reinforcement means of easy construction.
Background technology
At present, methods such as steel-bonded reinforcement, sticking carbon fiber reinforcement, enlarging section reinforcing or the reinforcing of external prestressing pull bar are adopted in the reinforcing of building structure frame beam more.When adopting steel bonding, sticking carbon fiber or enlarging section reinforcement means that Vierendeel girder is reinforced, all be that the bearing capacity of Vierendeel girder own is reinforced raising, the beam-ends moment of flexure of Vierendeel girder can increase to some extent, can increase the moment of flexure burden of post; When adopting external prestressing pull bar reinforcement means that Vierendeel girder is reinforced, break floor, it is difficult to wear the pull bar construction, and tension stress control is complicated.
Summary of the invention
In order to overcome the deficiency of steel-bonded reinforcement, sticking carbon fiber reinforcement, enlarging section reinforcing and external prestressing pull bar reinforcement means, the invention provides a kind of reinforcement means of building structure frame beam, the reinforcement means of this Vierendeel girder not to Vierendeel girder strengthen, ruggedized construction only gives post with the form of vertical concentrated force with the Load Transfer of being born, original structure is not produced newly-increased moment of flexure, simple in structure, easy construction.
The technical solution adopted for the present invention to solve the technical problems is: the both sides in Vierendeel girder two newel posts, certain altitude is respectively done a bearing at the bottom of being positioned at Vierendeel girder, article two, identical girder truss or solid web girder freely-supported are shelved on the bearing of post both sides, and girder truss or solid web girder top are than omiting at the end at the bottom of the Vierendeel girder; Article two, girder truss or solid web girder connect a transfer beam at Vierendeel girder mid point position, and this transfer beam holds out against bottom surface, Vierendeel girder middle part; Article two, girder truss or solid web girder link to each other by many lateral stability bars, guarantee stability; As required, two identical girder trusses or solid web girder also can add a certain amount of distortion in advance, form prestressing force, strengthen consolidation effect.
The invention has the beneficial effects as follows, can be original structure not being produced under the situation of moment of flexure, simple in structure, easy construction.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is the structure principle chart of the embodiment of the invention.
Fig. 2 is the 1-1 sectional view of Fig. 1.
Fig. 3 is the 2-2 sectional view of Fig. 1.
(1) treats that reinforcing frame sets a roof beam in place (2) floor plate, (3) frame column, (4) post upper bracket, (5) girder truss or solid web girder, (6) transfer beam, (7) lateral stability bar among the figure.
The specific embodiment
In Fig. 1, post upper bracket (4) is fixed on the frame column (3), article two, girder truss or solid web girder (5) connect by many lateral stability bars (7), freely-supported is shelved on the post upper bracket (4), transfer beam (6) two ends are connected with two girder trusses or solid web girder (5), and hold out against and treat the set a roof beam in place mid point bottom surface of (1) of reinforcing frame.The part floor load is delivered to two girder trusses or solid web girder (5) by transfer beam (6), passes to frame column (3) by post upper bracket (4) again, forms complete force path, has been equivalent to reduce the fractional load of Vierendeel girder, reaches the purpose that reinforcing frame is set a roof beam in place.
Claims (1)
1. building structure frame beam equivalence off-load reinforcing method, bearing is done in both sides in Vierendeel girder two newel posts, article two, girder truss or solid web girder freely-supported are shelved on the bearing, the transfer beam that two ends connect girder truss or solid web girder holds out against the Vierendeel girder bottom surface, it is characterized in that: two girder trusses or solid web girder hold out against the Vierendeel girder bottom surface by transfer beam, and freely-supported is shelved on the frame column side supports.
