Description

Technical Field

[0001] The present invention relates to the technical field of assembled structures, and more specifically, to a beam-column connection node of an assembled frame structure integrating pulling and shearing and a construction method thereof. Background Art

[0002] Prefabricated concrete frame structure refers to a concrete structure assembled by prefabricated concrete components through reliable connection methods, including prefabricated integral concrete structure, fully prefabricated concrete structure, etc. In construction engineering, it is referred to as prefabricated building; in structural engineering, it is referred to as prefabricated structure. Prefabricated components refer to concrete components prefabricated in factories or on-site, such as beams, slabs, walls, columns, etc. Prefabricated concrete frame structure is composed of prefabricated concrete beams and prefabricated concrete columns connected in a rigid or hinged form. Compared with wall units, beam and column units are easier to modularize, standardize and finalize, which is conducive to the use of unified molds for assembly line manufacturing in factories; at the same time, the spatial layout of prefabricated concrete frame structure is more flexible, and the component connection forms are diverse, which is conducive to mechanized and efficient hoisting on site. It can be said that prefabricated concrete frame structure has unique advantages in promotion and application in the process of building industrialization, and can be widely used in public buildings and civil residential buildings such as schools, hospitals, office buildings, etc.

[0003] The connection of prefabricated frame beams and columns can be divided into two parts: the connection between columns and the connection between beams and columns. At present, the connection of prefabricated frame beams and columns mostly adopts the mode of cast-in-place nodes or steel node connection. Both of these connection forms have certain application difficulties and limitations.

[0004] The node pouring connection method is to prefabricate the assembled frame beams and columns, and reserve the node area of ​​the assembled beams and columns. During the installation process, the beam end steel bars are inserted into the column end nodes, and the beam-column connection is formed by pouring concrete; and the columns are connected by sleeve grouting technology. This connection method has several problems in the specific installation process: First, when multiple assembled frame beams need to be connected to columns, the steel bars at their ends are dense, which can easily cause difficulties in concrete pouring; second, it is necessary to partially support the formwork of the column end nodes, and the installation process is labor-intensive and time-consuming; third, there are many steel bars at the beam ends and column ends, which are easy to collide with each other during installation, causing installation difficulties; fourth, it is difficult to intuitively control the quality of the sleeve grouting connection at the bottom of the column, and when the building volume is small, it is difficult to organize a professional team to carry out grouting installation, so it is easy to form quality risks.

[0005] The usual practice of using steel node connection is to embed steel end caps at the ends of beams and columns, and connect the steel end caps to the steel nodes of beam and column nodes to achieve the connection of assembled beams and columns. This connection method has several problems: first, the force transmission mechanism is complex, there are multiple force transmissions from concrete to end nodes, and from end nodes to beam-column nodes, there are many key points for quality control, and it is difficult to manufacture and install; second, because the nodes need to concentrate on handling the transmission of tension, shear force and bending moment, the amount of steel used in this area is often large and the cost is high; third, some connection forms also have the situation where the steel structure protrudes from the column or beam.

[0006] In summary, how to achieve simplicity, efficiency, low cost, high quality and easy control of beam-column connections in prefabricated frame structures is an urgent problem to be solved by technical personnel in this field. Summary of the invention

[0007] In order to solve the problems of easy collision of steel bars, difficulty in pouring concrete, difficulty in quality control, and high cost in the on-site installation of beam-column nodes of assembled frame structures, the present invention adopts the following technical solutions: The above technical objectives of the present invention are achieved through the following technical solutions: the assembly frame structure beam-column connection node with integrated pulling and shearing comprises an assembly frame column and an assembly frame composite beam, wherein the assembly frame column body is provided with a groove for placing the composite floor slab at the floor slab position; the groove is pre-embedded with a first steel bar threaded sleeve for installing the upper steel bar of the slab; the groove is pre-embedded with a second steel bar threaded sleeve for installing the upper steel bar of the beam; the assembly frame column is pre-embedded with an I-shaped connector below the groove for installing the assembly frame composite beam; the assembly frame column is pre-embedded with a small-diameter steel bar threaded sleeve below the I-shaped connector for installing masonry tie bars; the end of the assembly frame column beam is pre-embedded with a diagonal connector; the assembly frame composite beam is provided with a notch matching the I-shaped connector at the lower part of both ends of the beam, and the second steel bar threaded sleeve is connected to the assembly frame column through the upper steel bar of the beam; The groove has a range of floor height, the groove depth direction is perpendicular to the column surface, the groove depth is ≤15mm, 2 / 3 of the groove depth is used to place the floor, and 1 / 3 of the groove depth is used for error coordination during production and installation; The embedded position of the first steel bar threaded sleeve should be determined according to the steel bar arrangement on the upper part of the floor slab; The second steel bar threaded sleeve is pre-buried in the corresponding position of the upper steel bar of the frame beam in the connection area between the assembled frame column and the assembled frame composite beam, and the second steel bar threaded sleeve adopts a finished sleeve with an enlarged tail or a transverse steel bar placed therein; The I-shaped connector is installed at a bottom position of the frame beam corresponding to the connection area between the assembled frame column and the assembled frame composite beam. The I-shaped connector and the assembled frame column are cast together to form a whole.

[0008] The present invention is further configured as follows: a third steel bar threaded sleeve is pre-embedded in the center position on the upper side of the notch of the assembled frame composite beam, and the bolt used in conjunction with the third steel bar threaded sleeve is an internal angle bolt, which passes through the upper opening of the embedded I-shaped connecting piece and is connected and fastened to the third steel bar threaded sleeve.

[0009] The present invention is further configured as follows: the assembled frame composite beam also includes beam bottom steel bars, open stirrups, perforated thin steel plates, and shear reinforcement steel bars. The beam bottom steel bars, open stirrups, perforated thin steel plates, and third steel bar threaded sleeves are all prefabricated, installed, and integrally cast in the factory.

[0010] The present invention is further configured as follows: the two shear reinforcing steel bars are located in the end cross-section reduction area of ​​the prefabricated frame composite beam, the two shear reinforcing steel bars are horizontally arranged and simultaneously used as frame bars for the open stirrups, and the total cross-sectional size of the shear reinforcing steel bars is greater than or equal to the total cross-sectional size of the steel bars at the bottom of the beam.

[0011] The present invention is further configured as follows: a fourth steel bar threaded sleeve is provided at the bottom of the assembled frame composite beam, the fourth steel bar threaded sleeve is connected to the steel bar at the bottom of the beam, and the steel bar at the bottom of the beam is bent at the beam end to be connected to the fourth steel bar threaded sleeve.

[0012] The present invention is further configured as follows: the I-shaped connector adopts an integral casting structure or a cutting and welding structure; after the I-shaped connector is manufactured, it is cast integrally with the assembled frame column and connected to the concrete part through anchor bars; the anchor bars can be in the form of steel bars or steel plates; the I-shaped connector includes an end plate and a vertical connecting plate; the end plate includes an embedded end plate and a connecting end plate; the vertical connecting plate includes an upper horizontal connecting plate and a lower horizontal connecting plate; the embedded end plate is embedded in the concrete structure; a reserved opening is provided on the connecting end plate and corresponds to the fourth steel bar threaded sleeve; a centrally arranged opening is provided on the upper horizontal connecting plate and corresponds to the third steel bar threaded sleeve; the lower horizontal connecting plate is used to transmit the steel bar tension at the bottom of the beam and is located at the bottom of the embedded I-shaped connector.

[0013] The present invention is further configured as follows: the embedded I-shaped connector is completely filled with solid material after the assembled frame columns and assembled frame composite beams are installed.

[0014] According to the above-mentioned method for connecting beam-column joints of a tension-shear integrated assembled frame structure, the following steps are included: The first step is to install and position the assembled frame columns; The second step is to hoist the assembled frame composite beam after the frame columns at both ends of the beam are fixed; The third step is to align the third steel bar threaded sleeve embedded in the upper part of the lower notch of the assembled frame composite beam with the reserved hole at the top of the embedded I-shaped connector, and install the inner angle bolts to position and stabilize the assembled frame composite beam; The fourth step is to fasten the fourth steel bar threaded sleeve to the I-shaped connector by applying force to the bottom of the assembled frame composite beam; Step 5: After the assembled frame composite beams and columns are reliably connected, the composite floor slabs are laid; Step 6: Arrange pre-buried pipelines, lay and install steel bars on the upper part of the floor slab; Step 7: Connect the upper reinforcement of the beam to the second reinforcement threaded sleeve pre-buried in the frame column; Step 8: Tie the upper reinforcement of the beam; The ninth step is to pour concrete on the overlapping parts of beams and slabs to form a whole.

[0015] In summary, the present invention has the following beneficial effects: 1. Separate the beam-column connection from the column-column connection of the prefabricated frame structure, and raise the column-to-column connection to the middle of the floor height, which reduces the density of steel bars at the intersection of beams and columns at the floor position and reduces the difficulty of installation and pouring.

[0016] 2. Prefabricate the beam-column intersection nodes of the prefabricated frame structure in the factory in advance. Considering that the pre-embedded steel threaded sleeves and connecting anchor bars in the prefabricated frame column are prone to collision with the vertical steel bars and horizontal stirrups of the column, prefabricating this part in the factory can coordinate the steel bar collision problem in advance, reduce the difficulty of on-site installation, and eliminate the need for additional formwork, thereby reducing construction costs.

[0017] 3. It provides a reliable node for connecting prefabricated frame beams and columns. Different connection methods are used according to the characteristics of the stress-bearing steel bars in different parts of the beam, which simplifies the installation process. The upper steel bars of the prefabricated frame composite beam are directly stress-bearing steel bars, which are directly connected to the frame column through the pre-buried steel bar threaded sleeve to ensure the connection quality. The lower area of ​​the beam mainly bears pressure, and the lower steel bars of the beam are connected to the prefabricated frame column through the I-shaped connector pre-buried in the column. Importantly, the quality control of these two connection methods is extremely intuitive, which can effectively reduce the structural safety hazards caused by non-standard on-site construction operations.

[0018] 4. Pre-embedded small-diameter steel bar threaded sleeves are arranged along the height direction of the prefabricated frame columns to install masonry tie bars, which improves the integrity of the prefabricated frame structure and the masonry structure to be built later and the convenience of later masonry.

[0019] 5. The I-shaped connectors embedded in the columns of the assembled frame are used not only as horizontal connections for the steel bars at the bottom of the beams, but also as temporary supports during the installation of beams and columns. During the installation process, the embedded I-shaped connectors are connected and fixed to the composite beams of the assembled frame through high-strength internal angle bolts, which improves the integrity of the beam-column installation, effectively improves construction efficiency, and reduces construction costs.

[0020] 6. A groove with the same height as the plate thickness is set at the floor plate position to place the composite floor plate, thereby improving the shear resistance of the junction; the upper steel bars of the floor plate are connected with the steel bar threaded sleeves embedded in the corresponding positions of the frame columns to improve the integrity of the plate and column and enhance the crack resistance of this area.

[0021] 7. I-shaped connectors and some steel bar threaded sleeves embedded in the assembled frame column are used. The overall steel consumption is small, and the connection nodes do not protrude from the traditional beam-column range, which is more economical. BRIEF DESCRIPTION OF THE DRAWINGS
