The connecting beam of the main building and the podium of the utility model is a rigid concrete structure, which is a composite structure formed by a steel frame covered with reinforced concrete. Due to the mutual restraint between the steel skeleton and the high-strength concrete, the stiffened concrete structure can more effectively exert the respective advantages of the steel and concrete materials, overcome the shortcoming of local buckling of the steel structure, increase the ductility of the structure and components, and improve the Due to the poor ductility of high-strength concrete itself, it is not conducive to the brittle characteristics of earthquake resistance; in addition, compared with reinforced concrete structures, the use of stiff concrete structures effectively reduces the cross-sectional size of components, increases the use space, and can The beam-column section is reduced, the axial compression ratio is adjusted, and the bearing capacity of the structure is improved; compared with the steel structure, the rigid concrete structure saves the amount of steel, reduces the cost, and improves the fire resistance and anti-corrosion performance.

The construction steps of the connecting beams of the main building and the podium of the present utility model are described in detail below:

Hoist and install the steel columns of the main building's rigid columns and the steel columns of the podium's rigid columns, and set up external frames.

The span of the connecting beam between the main building and the podium is large (some beams have a span of more than 14m). According to the principle of setting the conventional construction joints at 1/3 position, it will cause inconvenience to the hoisting of the rigid columns of the main building. Only 1.2m long corbels are set on the sex column.

Weld multiple sleeves on the rigid steel column flange of the main building to connect the longitudinal main bars of the steel frame. On the flange of the podium stiffened steel column, the ribbed plate is used to connect the main reinforcement of the reinforced skeleton.

During the construction phase of the main building, the reserved longitudinal bottom bars under the orthographic projection section of the steel beams are 100mm shorter than the corbels, and the main bars at the other positions are staggered adjacently by a lap length reserved and the shortest is not less than 1200mm, so that the in operation. All reserved main tendons are protected with protective caps after they are threaded. After the rigid columns of the main building have been poured and the formwork removed, the construction joints shall be chiseled and cleaned up.

During the construction of the podium, in order to avoid the influence of the outer frame of the main building, the profiled steel is first hoisted to the board surface, and then the profiled steel is hoisted and positioned from the bottom to the top of the board surface, and then welded and fixed after it is in place.

In order to facilitate the operation of the workers, the podium beam slab formwork frame is erected with a quick-release frame, and a one-step frame is reserved at the bottom of the beam, and the bottom formwork of the beam is not installed for the time being. At the same time, when laying the floor bottom formwork, a width of 1m is reserved on one side of the stiff beam as the installation port for the bottom reinforcement of the beam, so that the bottom reinforcement of the beam can be bound.

Install stiff beam gluten and insert all stirrups. The stirrups are not positioned and bound temporarily. The main reinforcement and stirrups are erected by steel pipes at intervals of 1m at the bottom of the gluten, so that the bottom reinforcement can be penetrated.

Install the beam waist bars and beam bottom bars, and after all the waist bars and longitudinal bottom bars are penetrated, position all the stirrups according to the design spacing, and bind them. Among them, the longitudinal bottom rib is divided into two sections, the first section is first installed on the side connected by the straight thread of the main building, and then the second section is connected with a positive and negative wire sleeve. The end of the second section is connected to the stiffening plate of the podium. All waist bars are bent at the ends, and the bent sections are welded to the steel beam. After all the waist bars and bottom bars are installed, adjust the spacing of the stirrups, and finally tie the stirrups.

After completing the binding of steel bars, remove the springboard of the operating platform at the bottom of the beam, supplement the remaining support frame, insert the adjustable U bracket, install the beam bottom mold and the back corrugation in place, and adjust the adjustable U bracket to the design elevation as a whole.

Install the side formwork of the connecting beam and the reserved bottom formwork of the floor slab, and finally pour the concrete in the space enclosed by the formwork after binding the slab reinforcement to complete the construction.

The beneficial effects of the connecting beams of the main building and the podium of the utility model are:

By setting the first corbel and the second corbel to connect the profiled steel and pouring concrete, the utility model forms the connecting beam which is connected and fixed to the rigidity column of the main building and the rigidity column of the podium building. In the prior art, when the distance between the main building and the podium is too large, in order to ensure sufficient bearing capacity, the cross-sectional size of the concrete structural beam is large and takes up too much space, which affects the construction of other structures.

The present invention has been described in detail above with reference to the embodiments of the accompanying drawings, and those of ordinary skill in the art can make various modifications to the present invention according to the above description. Therefore, some details in the embodiments should not be construed to limit the present invention, and the present invention will take the scope defined by the appended claims as the protection scope of the present invention.
