Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of beam and column reinforcement, in particular to a beam and column node reinforcement structure of a concrete building. Background Art
[0002] The beam-column joints of reinforced concrete frame structures, also known as the core joint area, are a crucial component of the main structure. Earthquake damage to frame structures often occurs in the core areas of column and beam-column joints. Joint failure primarily results from shear and reinforcement anchorage failure, which can, in severe cases, lead to the collapse of the entire frame. However, in engineering practice, insufficient attention is often paid to joint construction, and joint quality control is lax.
[0003] As attached Figure 3 As shown in the figure, the beam-column node structure commonly used in existing concrete buildings, in which the main reinforcement of the beam and the main reinforcement of the column intersect vertically, is generally only tied with wire at the intersection. This node steel skeleton structure basically cannot provide rigid support between the beams and columns. When the main body of the building with unstable geology is affected by factors such as foundation vibration and settlement, it is easy to break at the beam-column node, thus posing a safety hazard. Utility Model Content
[0004] In response to the above problems, the utility model provides a beam-column node reinforcement structure for concrete buildings, which uses L-shaped connecting bars, anchor connectors and I-beam inclined steel to effectively improve the stiffness of the beam-column nodes of the concrete building frame, making it less likely to break at the beam-column nodes, thereby avoiding safety hazards.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] A beam-column joint reinforcement structure for a concrete building comprises connecting bars and anchor connectors. The connecting bars are L-shaped, with one end of the connecting bars fixed to the crossbeam and the other end fixed to the column. One end of an I-beam diagonal steel is fixed to the crossbeam via the anchor connector, while the other end of the I-beam diagonal steel is fixed to the column via the anchor connector.
[0007] Furthermore, the anchoring connector includes an embedded sleeve, an embedded plate and a ring. The embedded sleeve passes through both ends of the building body. A ring is fixed in the middle of the inner cavity of the embedded sleeve. The embedded plate passes through multiple embedded sleeves. The embedded plate is perpendicular to the embedded sleeve. One end of the bolt is fixed to the embedded plate inside the embedded sleeve, and the other end of the bolt is fixed to the I-beam inclined steel.
[0008] Furthermore, the I-beam oblique steel includes a rib plate and an end plate, one end of the end plate is fixed to one end of the rib plate, and the other end of the end plate abuts against the building body and is fixed with bolts.
[0009] Furthermore, the material of the embedded sleeve is polyvinyl chloride.
[0010] The utility model has the following beneficial effects:
[0011] 1. The utility model uses L-shaped connecting bars, anchor connectors and I-beam inclined steel to effectively improve the rigidity of the beam-column joints of the concrete building frame, making it less likely to break at the beam-column joints, thereby avoiding safety hazards.
[0012] 2. The utility model provides I-shaped diagonal braces at the inner corners on both sides of the columns and beams to provide external support and reinforcement, thereby improving the stiffness of the structure.
[0013] 3. The I-shaped brace of the present invention is connected to the embedded anchor connector by bolts, which is more reliable and stable than the ordinary expansion bolt installation.
[0014] 4. The utility model fixes and welds the original beam main reinforcement and column main reinforcement at the node through the connecting reinforcement 3, which has a stronger connection stiffness than the traditional wire binding. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0021] like Figure 1-Figure 2 As shown, the beam-column node reinforcement structure of the concrete building of this embodiment includes a connecting rib 3 and an anchor connector 4. The connecting rib 3 is L-shaped, one end of the connecting rib 3 is fixed to the crossbeam 1, and the other end of the connecting rib 3 is fixed to the column 2; one end of the I-beam diagonal steel is fixed to the crossbeam 1 through the anchor connector 4, and the other end of the I-beam diagonal steel is fixed to the column 2 through the anchor connector 4.
[0022] This utility model uses L-shaped connecting bars 3, anchor connectors 4, and I-shaped diagonal steel to effectively improve the rigidity of the concrete building frame beam-column joint, making it less likely to break at the beam-column joint, thereby avoiding safety hazards. By providing I-shaped diagonal braces at the inner corners of the columns 2 and beams 1, they provide external support and reinforcement, improving the rigidity of the joint. The connecting bars 3 are fixedly welded between the original beam main bars 6 and column main bars 7 at the joint, providing a stronger connection rigidity than traditional wire 8 tying.
[0023] Furthermore, the anchor connector 4 includes an embedded sleeve 41, an embedded plate 42 and a ring 43. The embedded sleeve 41 passes through both ends of the building body. A ring 43 is fixed in the middle of the inner cavity of the embedded sleeve 41. The embedded plate 42 passes through multiple embedded sleeves 41. The embedded plate 42 is perpendicular to the embedded sleeve 41. One end of the bolt 44 is fixed to the embedded plate 42 inside the embedded sleeve 41, and the other end of the bolt 44 is fixed to the I-beam inclined steel.
[0024] At least one pair of bolt holes is provided on the embedded plate 42, and a collar 43 is fixedly provided at the position of the bolt hole. The inner diameter of the collar 43 is larger than the outer diameter of the head of the bolt 44. Collars 43 are provided on both sides of the embedded plate 42, and embedded sleeves 41 are respectively connected by the collars 43. During the pouring construction, the embedded sleeves 41 play the role of isolating concrete.
[0025] Furthermore, the I-beam includes a rib plate 51 and an end plate 52 . One end of the end plate 52 is fixed to one end of the rib plate 51 , and the other end of the end plate 52 abuts against the building body and is fixed with a bolt 44 .
[0026] The I-shaped brace is connected to the built-in embedded plate 42 by bolts 44, which is more reliable and stable than ordinary expansion bolt installation.
[0027] Furthermore, the embedded sleeve 41 is made of polyvinyl chloride.
[0028] The method of using the utility model is as follows:
[0029] During construction, conventional construction methods are used to erect beam-column formwork and the reinforcement skeleton of the beams and columns. When erecting the reinforcement skeleton, the connecting ribs 3 are welded and fixed to the original reinforcement skeleton. According to the installation position of the I-beam brace, the three anchor connectors 4 are placed in corresponding positions. The anchor connectors 4 are welded and fixed to the connecting ribs 3. Finally, the formwork is completely installed. After installation, the end of the embedded sleeve 41 on the anchor connector 4 abuts the inner wall of the formwork. After pouring is completed, through holes for installing bolts 44 are formed on the beam 1 and the column 2 respectively. Then, one end of the I-beam brace is installed at the bottom of the beam 1 with the corresponding bolts 44, and the other end is fixed to the side of the column 2 by bolts 44, thus completing the installation of the reinforcement node.
[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
