Background

With the continuous development of the building industry, common civil buildings such as houses and offices are not changed. Civil buildings are not only gradually changed in appearance but also changed in internal space layout. One of common structural forms of shear wall structures is widely applied to residential construction due to the flexibility of structural arrangement and good earthquake resistance of the structure.

In the shear wall structure, the connecting beam is used as a main energy consumption component of the structure in the earthquake-proof design and is the component with the first damage to the structure under the earthquake condition. Conventional structural designs therefore generally do not allow structural main beams to rest on the coupling beams. If the main beam is laid on the connecting beam, the connecting beam can be damaged preferentially in earthquake, which can cause the main beam of the structure to be damaged immediately, thereby affecting the safety of the structure.

The above prior art solutions have the following drawbacks: because the connecting beam does not allow the structure girder to be laid in the shear wall structure, the structure floor arrangement is not established, and the situation is met in the practical engineering project, if the structure is not established, the previous design work is abandoned, the repeated work of the design work is increased, the time schedule of the design is seriously influenced, and further improvement is needed.

Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Referring to fig. 1 and 2, for the utility model discloses a link vertical armpit structure under roof beam, including two shear force walls 1 that parallel, connect even roof beam 2 between two shear force walls 1 and shelve girder 3 on even roof beam 2 perpendicularly, be provided with on the bottom surface of even roof beam 2 with shear force wall 1 fixed mutually vertical armpit section 4 that adds, vertical armpit section 4 and even roof beam 2, shear force wall 1 pouring are even as an organic whole. The section of the vertical haunching section 4 is rectangular and is positioned below the placement point of the main beam 3, and the length of the part of the vertical haunching section 4, which exceeds the main beam 3, is equal to one time of the width of the main beam 3. The vertical haunching under the connecting beam 2 is adopted, the energy consumption function of the energy consumption section of the connecting beam 2 in the earthquake working condition is kept, meanwhile, the vertical haunching section 4 is not damaged, and the shelving function of the main beam 3 can be borne. Thereby both having satisfied the antidetonation demand, guaranteed simultaneously that the structure of the structural component beyond even roof beam 2 requires and the security of bearing. Thus, in the design process, if the conditions are met, the building structure design does not need to be subjected to large plane adjustment, and the design period can be saved.

Referring to fig. 1 and 2, an armpit transition section 41 with a triangular cross section is arranged on the outer side surface of the vertical armpit section 4 close to the energy consumption section of the connecting beam 2, and the cross section of the armpit transition section 41 is in an isosceles right triangle shape.
