Embodiment 1
[0063] Such as Figure 1~15 Among them, a construction method of a connected beam type assembled building structure, comprising the following steps:
[0064] s1. Prefabricate components in the workshop, including at least the inner and outer layers of columns 1, beams 2, floors 5 and shear walls 3;
[0065] Position the joint of column 1 at the position between the floors;
[0066] s2, hoisting column 1;
[0067] s3, install the shear wall 3;
[0068] s4, the hoisting beam 2 is placed on the corbel support 102 of the column 1, and the beam 2 is a prestressed beam;
[0069] s5. Connect the ends of the beam 2 to each other or to the column 1 by connecting the tensioning wire rope 26;
[0070] s6, hoisting the floor slab 5 on the beam 2;
[0071] The above steps are repeated in turn to obtain the assembled construct.
Embodiment 2
[0073] On the basis of Example 1, the preferred scheme is as Figure 1~15 , including the following steps:
[0074] s1. Prefabricate components in the workshop, including at least the inner and outer layers of columns 1, beams 2, floors 5 and shear walls 3;
[0075] The joint position of column 1 is located between the floors, and the joint position can be set by itself according to the construction requirements. It can be set on each floor, and the joint position can also be set on two or three floors. At the position where the reinforcement of the shear wall needs to be connected, the prefabricated column 1 is provided with a reserved transverse reinforcement. A socketed steel pipe 103 is provided in the column 1, and the socketed steel pipes 103 of different columns 1 are connected to each other through ends;
[0076] A column reinforcement 101 is arranged around the socketed steel pipe 103, and the inside and outside of the socketed steel pipe 103 are poured with concret...

Abstract
The invention provides a construction method of a connecting beam type spliced building structure. The construction method comprises the following steps that members are prefabricated in a workshop, including at least inner layers and outer layers of columns, cross beams, slabs and shear walls; joints of the columns are located at the positions among the slabs; the columns are hoisted; the shear walls are installed; the cross beams are hoisted and arranged on bracket supports of the columns, wherein the cross beams are prestressed beams; the ends of the cross beams are connected with one another or are connected with the columns by connecting tension steel wires ropes; the slabs are hoisted on the cross beams; a spliced building is obtained by repeating the steps in sequence. The problem can be solved that an existing assembled structure is poor in compressive strength and easily produces stress concentration, the problem of poor anti-seismic property of a cast-in-place concrete structure can be also solved, and the influence on a linear construction period is not large. Members can be decreased by 30%-50%, the hoisting weight can be reduced by 20%-35%, and the construction periodis remarkably shortened compared with a cast-in-place structure. The overall anti-seismic property of the building is effectively improved.
Description
technical field [0001] The invention relates to the field of assembled structures, in particular to a construction method of a connecting beam type assembled building structure. Background technique [0002] The prefabricated buildings in the prior art mostly adopt prefabricated column, beam and wall panel structures, and the prefabricated components are fixedly connected by connectors to form a whole. However, the lateral stiffness of this prefabricated assembly structure in high-rise buildings is insufficient. In the cast-in-place construction technology of structures, the construction method of pouring columns and beams as a whole is adopted, but this construction method has the defects of slow construction progress and poor seismic performance. [0003] Chinese patent document CN106193292A records a steel frame-assembled integral reinforced concrete shear wall structure system, which adopts a steel frame composed of steel columns and steel beams, a prefabricated wall pa...
