Problems solved by technology

In this method, since the nodes are cast-in-place, the construction of the upper layer needs to wait until the concrete of this layer reaches a certain strength, and the construction period is longer. Compared with the traditional cast-in-place structure, it has no obvious advantages, and the quality of the nodes cannot be guaranteed.

Embodiment 1

[0038] like Figure 1 to Figure 7Shown is the first embodiment of the prefabricated concrete frame structure of the present invention, including prefabricated columns 1, prefabricated composite beams 2, prefabricated composite panels 3, and prefabricated composite nodes for combined connection of prefabricated composite beams 2 and prefabricated columns 1 4. The prefabricated composite node 4 is plugged into the precast column 1, one end of the prefabricated composite beam 2 is connected to the prefabricated composite node 4, and the other end is socketed with the adjacent prefabricated composite beam 2, the prefabricated composite beam 2 is connected to the precast column 1 Vertical arrangement; multiple groups of prefabricated laminated beams 2 are surrounded and connected to form a frame structure, and prefabricated laminated panels 3 are placed on the frame structure. The frame structure of this embodiment is a square structure.

[0039] like figure 2 As shown, the two ...

Embodiment 2

[0045] like Figure 8 Shown is the second embodiment of the prefabricated concrete frame structure of the present invention, this embodiment is similar to the first embodiment, the difference is that the prefabricated composite node 4 of this embodiment is a square structure, and the prefabricated composite beam 2 It is four groups and connected to the four sides of the prefabricated combination node 4 to form a cross structure. Compared with Embodiment 1, this embodiment is applicable to the application scenario where multiple frame structures are arranged side by side. Multiple frame structures share the prefabricated composite nodes 4 and prefabricated columns 1, which saves materials and does not affect the mechanical strength of the frame structures.

Embodiment 3

[0047] This embodiment is an embodiment of the construction technology of the assembled concrete frame structure, comprising the following steps:

[0048] S10. Fixing the prefabricated column 1;

[0049] S20. Insert the first longitudinal rib 41 of the prefabricated composite node 4 into the first socket 12, and grout to the inside of the first socket 12 through the first grouting hole 11, and connect the prefabricated composite node 4 to the prefabricated column 1;

[0050] S30. Connect the second longitudinal reinforcement 21 through the grouting sleeve 22, and grout into the grouting sleeve 22 through the second grouting hole 23, so as to realize the connection between the prefabricated composite beams 2;

[0051] S40. Place the prefabricated composite slab 3 on the prefabricated composite beam 2, and arrange floor reinforcement on the prefabricated composite slab 3, the floor reinforcement protrudes from the edge of the prefabricated composite slab 3 and connects with the ...

Abstract

The invention relates to the technical field of power grid dispatching, in particular to a prefabricated type concrete frame structure and a construction technology of the prefabricated type concreteframe structure. The prefabricated type concrete frame structure comprises prefabricated columns, prefabricated laminated beams, a prefabricated laminated slab and prefabricated combining joints usedfor combining and connecting the prefabricated laminated beams and the prefabricated columns. The prefabricated combining joints are connected with the prefabricated columns in an inserted manner. Oneend of each prefabricated laminated beam is connected to the corresponding prefabricated combining joint, and the other end of each prefabricated laminated beam is connected with the adjacent prefabricated laminated beam in a sleeved manner. Each prefabricated laminated beam is perpendicular to each prefabricated column. The multiple groups of prefabricated laminated beams are connected in a surrounding manner to form a frame-shaped structure. The prefabricated laminated slab is placed on the frame-shaped structure. According to the prefabricated type concrete frame structure, the prefabricated columns, the prefabricated laminated beams, the prefabricated laminated slab and the prefabricated combining joints all can be prefabricated according to the dimensions, the types of reinforcing steel bars and bearing capacity requirements of different joints, the prefabricated columns, the prefabricated laminated beams, the prefabricated laminated slab and the prefabricated combining joints are assembled into the frame structure, in this way, production efficiency can be effectively improved, and the problem that a construction period is long when a joint is manufactured by the adoption ofa cast-in-situ method is avoided.

Description

technical field [0001] The invention relates to the technical field of power grid dispatching, and more specifically, to an assembled concrete frame structure and its construction technology. Background technique [0002] At present, the prefabricated concrete frame structure is one of the most widely used, most researched and most concerned systems when applying assembly technology for engineering construction at home and abroad, because of its flexible architectural space layout, high prefabrication rate, environmental protection and energy saving and significant advantages It has been widely used due to its economic benefits. The node area of ​​the prefabricated concrete frame structure is its weak point, and the connection between the beam-column nodes directly affects the stability and earthquake resistance of the overall structure. safety is of great significance. [0003] The connection methods of beam-column joints of prefabricated concrete structures can be roughl...
