Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a reinforced concrete frame beam-column joint. Background Technology
[0002] In the field of civil engineering, reinforced concrete frame structure is the most commonly used structural form. With the diversification of building functional requirements, irregular columns and irregular beam grids are appearing more and more often. In engineering, it is common to encounter situations where curved beams need to be fixed to both sides of vertical support columns.
[0003] In the existing technology, precast reinforced concrete frame beam-column joints are mostly joints connecting straight beam structures. When applied to curved beams, they make point contact with the curved beams, which can easily generate large pressure on the local area of the curved beams. This can lead to uneven stress at the ends of the curved beams, resulting in potential dangers such as unstable connection or excessive stress that can easily damage the joint between the curved beams and the supporting columns. Therefore, a new type of reinforced concrete frame beam-column joint is needed. Utility Model Content

[0016] Preferably, slots are provided on both the left and right sides of the node column;
[0017] A plug is fixed to the side of the fixing plate near the node column, and the plug is inserted into the slot;
[0018] The node column is also equipped with a positioning element, which is used to limit the insertion of the plug after it is inserted into the slot, so that the plug cannot move.

[0034] Example: Reference Figure 1-3 The above-described reinforced concrete frame beam-column joint includes a joint column 1, with mounting plates 101 integrally formed at both the upper and lower ends of the joint column 1 for fixed connection with the reinforced concrete frame column.
[0035] A movable mounting structure 2 is detachably installed on the node column 1. An adjustable clamping assembly 3 is installed on one side of the movable mounting structure 2. The adjustable clamping assembly 3 includes:
[0036] The clamping strip 301 is movably mounted on the movable mounting structure 2. Multiple clamping strips 301 are provided, and the multiple clamping strips 301 slide horizontally on the movable mounting structure 2 or slide vertically with the movable mounting structure 2.
[0037] Fixed fin plate 302, multiple fixed fin plates 302 are provided and fixed to the opposite side of two adjacent clamping strips 301;
[0038] The tie fastener passes through two fixed fins 302 on the same side of the two clamping strips 301, and causes the two adjacent clamping strips 301 to clamp the ends of the arc beam of the reinforced concrete frame.
[0039] Based on the above structure, during installation, the workers first fix the mounting plate 101 to the support column using bolts (or pre-embedded bolts) and nuts, thereby fixing the node column 1. Then, by horizontally moving the two clamping strips 301, the two horizontally set clamping strips 301 are brought closer or further apart and placed on both sides of the upper or lower end of the arc beam. After all four clamping strips 301 are in place, the two vertically parallel clamping strips 301 are pulled and fixed by the tie fasteners, and the ends of the arc beam are clamped, thereby completing the fixed connection between the arc beam and the support column.
[0040] Compared to the line contact or point contact methods in existing technologies, this utility model adopts a surface contact clamping and fixing method, which avoids the instability of the end connection of the curved beam or the easy damage due to excessive force. It is not only stable to install, but also more suitable for the connection of reinforced concrete frame beams and columns of curved beams. It can also clamp and fix curved beams of various specifications, making it more applicable and with better actual use effect.
[0041] Furthermore, the fixed fin plate 302 is provided with through holes 305;
[0042] The clamping strip 301 is an arc-shaped strip with a rectangular cross-section. The two adjacent clamping strips 301 at the top and bottom are of the same length, and the two adjacent clamping strips 301 at the left and right are arranged in concentric circles.
[0043] The tie rod fastener includes a tie rod 303 and a tie bolt 304. The two ends of the tie rod 303 respectively pass through two through holes 305. The tie bolt 304 is screwed to the end of the tie rod 303. Each tie rod 303 has a tie bolt 304 screwed to both ends. The side wall of the tie bolt 304 abuts against the side wall of the fixing fin 302 away from the middle of the tie rod 303.
[0044] The axis of the horizontally extending tie rod 303 is the same as the radial direction of the arc-shaped extension line of the clamping strip 301.
[0045] Tighten two tie bolts 304 at both ends of the tie rod 303 so that the two clamping strips 301 clamp the ends of the arc beam. The ends of the arc beam can be fixed by the tension force, and the connection is stable and the operation is convenient and quick.
[0046] Furthermore, the active mounting structure 2 includes:
[0047] The fixing plate 201 is fixed to the node column 1 by means of a connector, and the fixing plate 201 has a vertically extending vertical groove 203.
[0048] The movable plate 202 is slidably connected to the vertical slide groove 203 by a slider and extends horizontally. The movable plate 202 is provided with a horizontally extending horizontal slide groove 204.
[0049] The end of the clamping strip 301 is slidably connected to the horizontal groove 204 via a slider.
[0050] By setting the fixed plate 201 and the movable plate 202, the clamping strip 301 can slide horizontally along the horizontal slide groove 204 and slide vertically along the vertical slide groove 203 with the movable plate 202, thereby meeting the installation requirements of different types of curved beams and making the reinforced concrete frame beam-column joint more widely applicable in actual use.
[0051] Furthermore, slots 102 are provided on both the left and right sides of the node column 1;
[0052] A plug 205 is fixed on the side of the fixing plate 201 near the node column 1, and the plug 205 is inserted into the slot 102;
[0053] The node column 1 is also equipped with a positioning component, which is used to limit the insertion block 205 after it is inserted into the slot 102, so that the insertion block 205 cannot move.
[0054] A first positioning hole 103 is provided on the node column 1. The first positioning hole 103 passes through the front and rear sides of the node column 1 and communicates with the slot 102.
[0055] The insert 205 is provided with a second positioning hole 206. There are two second positioning holes 206, which are respectively provided through the upper and lower and front and rear side walls of the insert 205. The two second positioning holes 206 are connected to each other.

Both ends of the positioning screw 4 are screwed with positioning bolts 401, and one side of the positioning bolts 401 abuts against the side wall of the node column 1.
[0057] In use, workers can install the fixing plate 201 by inserting the insert 205 into the slot 102, and use the positioning screw 4 and positioning bolt 401 to limit the position of the insert 205, thereby fixing the position of the insert 205. This facilitates the installation or disassembly of the movable mounting structure 2 and the adjustable clamping component 3 installed on the movable mounting structure 2. At the same time, by rotating the fixing plate 201 to different insertion angles, the installation angle of the movable mounting structure 2 and the adjustable clamping component 3 can be changed (the angles are changed to 90°, 180° and 270° respectively), thereby adapting to the clamping and installation requirements of curved beams with different extension directions, further expanding the applicability of this reinforced concrete frame beam-column joint, and making it more flexible and convenient to use.
[0058] The working principle of this utility model is as follows: In daily use, the operator first fixes the mounting plate 101 to the support column using bolts and nuts, thereby fixing the node column 1. Then, the fixing plate 201 is installed by inserting the insert block 205 into the slot 102, and the insert block 205 is limited by the positioning screw 4 and the positioning bolt 401, thereby fixing the position of the insert block 205, thus completing the overall installation of the movable mounting structure 2 and the adjustable clamping assembly 3. At this time, the operator only needs to move the two clamping strips 301 horizontally, so that the two horizontally set clamping strips 301 are close to or far from each other, and placed on both sides of the upper or lower end of the arc beam. When all four clamping strips 301 are in place, the two tie bolts 304 are tightened at both ends of the tie screw 303, so that the two clamping strips 301 clamp the end of the arc beam, and the end of the arc beam can be fixed by the tension, thereby completing the fixed connection between the arc beam and the support column.
[0059] Compared to the line contact or point contact methods in existing technologies, this utility model adopts a surface contact clamping and fixing method, which avoids the instability of the end connection of the curved beam or the easy damage due to excessive force. It is not only stable to install, but also more suitable for the connection of reinforced concrete frame beams and columns of curved beams. It can also clamp and fix curved beams of various specifications, making it more applicable and with better actual use effect.
