Embodiment 1

[0037] Embodiment one, as figure 2 As shown, the width of the two ends 22 of the main girder 2 is larger than the width of the middle part 21, and the middle part 21 and the end part 22 are connected in a stepped shape. The tops of the middle part 21 of the main beam 2 and the tops of both ends 22 are respectively provided with recesses 23 and 24, wherein the recess 23 of the middle part 21 is relatively shallow, and the recess 24 of the end part 22 is deep and penetrates to the end surface of the main beam 2. 21 both sides and end 22 both sides are of the same height. When pouring concrete on the floor, the recesses 23 and 24 at the top of the main beam 2 are also cast-in-place concrete to form the cast-in-place part of the main beam 2 .

Embodiment 2

[0038] Embodiment two, such as image 3 As shown, different from the first embodiment of the main beam, the width of the two ends 22 of the main beam 2 is equal to the width of the middle part 21, and the height of both sides of the end 22 is much lower than the height of both sides of the middle part 21, so the end A small amount of formwork is required on both sides of 22 for sealing.

[0039] Similarly, in the present invention, the secondary beam 3 can also adopt the following two structural modes:

[0040] Embodiment one, as Figure 4 As shown, the widths of the two ends 32 of the secondary beam 3 are larger than the width of the middle part 31 , and the middle part 31 and the end parts 32 are connected in steps. The tops of the middle part 31 of the secondary beam 3 and the tops of both ends 32 are respectively provided with recesses 33 and 34, wherein the recess 33 of the middle part 31 is relatively shallow, and the recess 34 of the end part 32 is relatively deep and...

Abstract

The invention discloses a prefabricated frame structure and a cascaded prefabrication construction method thereof. The prefabricated frame structure comprises stand columns (1), main beams (2) connected with the stand columns (1), secondary beams (3) connected with the main beams (2), and floors (5). Prefabricated members are adopted as the main beams (2) and the secondary beams (3) and are provided with reserved exposed steel bars. The floors (5) are laminated slabs, prefabricated slabs (51) are adopted for the lower portions of the floors (5), and concrete is cast on the tops of the prefabricated slabs (51), the main beams (2) and the secondary beams (3) on site so as to connect the prefabricated slabs (51), the main beams (2) and the secondary beams (3) together. By means of the prefabricated frame structure and the cascaded prefabrication construction method thereof, the on-site construction workload can be reduced more effectively, on-site slab nailing can be greatly reduced, and pollution and waste can be reduced; besides, manpower resources are greatly saved; the construction efficiency is effectively improved, and thus the construction period is shortened.

Description

technical field [0001] The invention relates to a building structure and a building method thereof, in particular to a frame structure using prefabricated parts and a series prefabricated building method thereof, and is especially suitable for buildings of all frame structures or frame-shear structures. Background technique [0002] The main prefabricated parts used in traditional frame structure buildings constructed by prefabricated parts assembly mode are: prefabricated secondary beams and prefabricated slabs. During construction, the column should be cast in place first, then the prefabricated secondary beam, prefabricated slab and cast-in-place main beam reinforcement should be installed, and finally the concrete should be cast in-situ on the prefabricated slab to combine the main beam, prefabricated secondary beam and prefabricated slab. The use of prefabricated parts can reduce the amount of on-site construction work, save labor and improve construction efficiency. H...
