Embodiment 1

[0059] Such as figure 1 Shown is a schematic diagram of a frame structure of Embodiment 1 of the present invention. The first floor of the prefabricated concrete column 1 is not disconnected, and the longitudinal connection nodes 3 are set at the height of 1.3m on each floor above the second floor. The longitudinal connecting node 3 is formed by groove welding the column connecting steel 101 protruding from two adjacent concrete prefabricated columns 1 up and down. Concrete prefabricated column 1 is prefabricated across floors, and can also be prefabricated at full height if site conditions permit.

[0060] A number of steel corbels 103 are provided on the side of the prefabricated concrete column 1, and the number of steel corbels 103 arranged on the sides, vertices, and interiors of the frame structure is different. According to the actual needs of the connection nodes, the number of steel corbels 103 The number can be 2 to 4, such as Figure 4 The number of steel corbels...

Abstract

The invention relates to the technical field of constructional engineering assembly, and discloses a dry rigid connection prefabricated assembled integral frame structure. The dry rigid connection prefabricated assembled integral frame structure comprises concrete prefabricated columns and concrete prefabricated beams; the upper and lower sections of each of the concrete prefabricated columns areconnected by groove welding of column-connecting section steel to form a longitudinal connection node of dry rigid connection; a steel bracket at the side of each concrete prefabricated column and beam-connecting section steel penetrating through both ends of each concrete prefabricated beam are connected through high strength bolts to form a horizontal connection node of dry rigid connection; andthe longitudinal connection node and the horizontal connection node are staggered in the vertical direction, the concrete prefabricated columns are prefabricated across floors, a plurality of layersof concrete prefabricated beams and a plurality of concrete prefabricated columns are connected to each other to form a prefabricated assembled integral frame structure. According to the dry rigid connection prefabricated assembled integral frame structure, an assembled frame of the post-cast concrete connection technology is replaced by the dry rigid connection technology, and the problems of theinstability of post-cast concrete connection and the difficulty of collision avoidance of steel bars are solved.

Description

technical field [0001] The invention relates to the technical field of construction engineering assembly, in particular to a dry rigid connection prefabricated assembly integral frame structure and a construction method thereof. Background technique [0002] Prefabricated buildings can achieve the green development requirements of "four festivals and one environmental protection", and have the advantages of high quality, high efficiency, environmental protection, and sustainable social development. The prefabricated integral concrete frame structure is the most widely used and successful structural system of prefabricated buildings at home and abroad, and has passed the test of strong earthquakes. The assembled integral frame must meet the seismic fortification requirements of the seismic fortification intensity of 8 degrees and below. The connected fabricated frame structure is particularly critical. [0003] The current mainstream assembled monolithic frame adopts the pre...
