Problems solved by technology

[0002] For a long time, the labor productivity of the construction industry has been increasing slowly. Compared with other industries and foreign counterparts, most enterprises have relatively backward construction technology, low construction efficiency, high labor intensity, high project quality and safety accidents, and common problems in project quality. As is often the case, construction costs continue to increase

Embodiment 1

[0033] Embodiment 1: Assembled prestressed structure of cast-in-place slab.

[0034] After the foundation is poured according to the design requirements, the steel strands are fixed to the embedded parts of the foundation at the centerline of each column foundation to provide a fixed end for the subsequent prestressing of the columns. Afterwards, start to hoist the bottom node columns. When hoisting the beam members of the adjacent spans, the following two construction techniques are adopted: spreading from the corners to the center, or spreading from the center to the sides.

[0035] Arrange the corners toward the center: After the assembly of the corner column 1a is completed, transport the horizontally and vertically adjacent beam members a and b to the storey height, erect one end on the pre-embedded angle steel 6 on the column, and fix the other end with equipment first. Then set up two node columns 2a, 3a adjacent to the longitudinal axis and the horizontal axis. Before ...

Embodiment 2

[0041] Embodiment 2: Prefabricated floor slab (with doors, windows and walls) prefabricated prestressed structure.

[0042] The preliminary process is the same as that of Example 1 until the assembly of the beam-column system is completed. The assembly method of the beam-column system can also adopt the above-mentioned two construction techniques of edge-to-center and center-to-edge, and then assemble the prefabricated slab and the beam, and adopt the following method: insert the elbow reinforcement of the prefabricated slab The plate is connected with the hole 9, and the basic fixing of the elbow steel bar can be completed at the bottom of the two to complete the combination of the beam and the plate. Next, if there is a prefabricated body of wall, the body of wall is embedded on the plate along the column side chute from top to bottom, and the reinforcing bar convex key 12 on the plate is fixed to the bottom of the body of wall from top to bottom. Complete the overall assem...

Abstract

The invention belongs to the technical field of construction, and relates to a full prefabricated pre-stress assembly type structure and a construction method thereof. The full prefabricated pre-stress assembly type structure is characterized in that a structural main body is of a frame structure; columns, beams, plates, doors and windows, walls and stairs are prefabricated by factories; grooves and holes are formed in the columns, beams, and plates according to a total design drawing, the quality of components can be ensured, complex operations such as template supporting, maintenance and demounting can be avoided in a construction site, and the full prefabricated pre-stress assembly type structure can save labors, is high in efficiency, is good in quality, is light and convenient, and can avoid construction pollution; compared the conventional assembly type structures, the full prefabricated pre-stress assembly type structure is characterized in that the assembly and stability are excellent; the size of a desired cross section is small at the request of an equal bearing capacity design value, and the anti-shock performance can be ensured. The full prefabricated pre-stress assembly type structure is environment-friendly, can save energy and reduce consumption, can meet the demand of a sustainable development strategy of the construction industry, can be widely used for variousmultiple high frame structures, and can achieve good economic and social benefits.

Description

technical field [0001] The invention relates to the field of civil engineering, and relates to a fully prefabricated prestressed assembled structure and a construction method thereof. Background technique [0002] For a long time, the labor productivity of the construction industry has been increasing slowly. Compared with other industries and foreign counterparts, most enterprises have relatively backward construction technology, low construction efficiency, high labor intensity, high project quality and safety accidents, and common problems in project quality. As is often the case, construction costs continue to increase. In the process of urbanization and urban modernization, construction enterprises must start from the perspective of improving construction efficiency, speeding up project progress, and reducing labor intensity, and work hard to comprehensively improve the level of construction technology, so as to approach and catch up with foreign advanced construction t...
