Problems solved by technology

[0003] However, the existing prefabricated concrete frame and frame-shear structure buildings have many deficiencies that limit the promotion and application of this type of structure.
For example, the prefabricated components are all solid concrete rods, the structure has a large dead weight, wastes building materials, and has higher requirements for construction machinery and hoisting equipment; the beam-column joints do not transmit force directly, and the reliability is poor, resulting in earthquake resistance and

Example Embodiment

[0051] Example 1:

[0052] by Figure 1-Figure 7 An assembled monolithic concrete frame structure system is shown, which includes a prefabricated column 1, a prefabricated beam 2 and a prefabricated floor slab 4. Among them, the precast column 1 is arranged vertically, and the precast beam 2 and the precast floor 4 are both arranged horizontally. The prefabricated column 1 and the prefabricated beam 2 constitute a frame body, and the several prefabricated columns 1 are arranged at intervals in a vertical and horizontal direction. The several prefabricated beams 2 are respectively arranged between two longitudinally adjacent prefabricated columns 1 and between two transversely adjacent prefabricated columns. The floor 4 is erected in the area surrounded by four prefabricated beams.

[0053] The prefabricated beam 2 is an ordinary reinforced concrete component. The prefabricated beam 2 is provided with a prefabricated beam reinforcement cage 72, and a block-shaped prefabricated beam...

Example Embodiment

[0058] Example 2:

[0059] by Figure 8-9 The shown assembly monolithic concrete frame structure system is different from the embodiment 1 in that the prefabricated floor slab 4 adopts the prefabricated concrete hollow slab, and the prefabricated column 1 and the prefabricated beam 2 are connected by a cover plate. Column node structure connection.

[0060] The ends of the prefabricated floor slab 4 are laid on the top end surface of the corresponding prefabricated beam 2, and the prefabricated floor slab 4 is formed by connecting a plurality of precast concrete hollow floor slabs 28 through the end concrete transverse joints and the side concrete longitudinal joints of the slab body. The butt ends of the two precast concrete hollow floor slabs 28 are laid on the beam tops of the corresponding precast beams 2, and the main grouting joint area 30 for concrete grouting is provided between the two butting ends of the two precast concrete hollow slabs 28. The main grouting joint area 3...

Example Embodiment

[0062] Example 3:

[0063] by Figure 10-Figure 11 The shown assembly monolithic concrete frame structure system is different from Embodiment 1 or Embodiment 2 in that the prefabricated column 1 and the prefabricated beam 2 are connected by a cross-connected fabricated frame beam-column node structure.

[0064] The prefabricated frame beam-column node structure adopting transverse connection includes a dark corbel 41 set on the beam of the prefabricated column 1, the dark corbel 41 is rectangular in cross section, and the dark corbel bolt hole is horizontally reserved on the dark corbel 41; The front side of the connection of the end of the beam 2 is provided with a notch groove that matches with the dark leg 41. The notch groove is a notch that is dug from the vertical axis of the precast beam 2 to one side. The notch and the cross-sectional shape of the dark leg 41 Same, the size of the notch is slightly larger than the concealed corbel to facilitate the assembly and fixing of th...

Abstract

The invention discloses an assembled monolithic concrete frame structure system and a frame shear structure system formed by the assembled monolithic concrete frame structure system. The assembled monolithic concrete frame structure system comprises precast columns, precast beams and precast floors, wherein the precast beams and the precast columns are connected to form a frame structure; the precast floors are arranged on the frame structure in an overlapping manner and are connected with the precast beams. The assembled monolithic concrete frame shear structure system comprises the assembled monolithic concrete frame structure system and precast sheer walls. According to the assembled monolithic concrete frame structure system and the frame shear structure system formed by the assembled monolithic concrete frame structure system, building materials can be saved, the structure self-weight is reduced, the construction speed is increased, the production efficiency is improved, the precast sheer wall bodies and seam construction are improved, the appearance and development of inclined cracks of the precast sheer wall bodies are reduced, and the anti-seismic working performance of the precast concrete frame structure system and the frame shear structure system formed by the precast concrete frame structure system is effectively enhanced.
