[0035] The front ends of the beam fixing parts of the four concrete beams (respectively concrete beam 1 2, concrete beam 2 3, concrete beam 3 4, concrete beam 4 5) are respectively provided with beam 1 clamping parts 20, beam 2 clamping parts 30, beam 3 clamping parts 40, beam 4 clamping parts 50, which are respectively installed on the front end surfaces of the right-angled trapezoidal table-shaped fixing parts 21 of concrete beam 1 2, concrete beam 2 3, concrete beam 3 4, concrete beam 4 5.

[0039] like Fig.11 , Fig.12As shown, the beam four engaging member 50 is composed of an inverted right-angled trapezoidal platform-shaped lower base 501 and a lying right-angled triangular prism-shaped side base 502 installed on the vertical side end surface of the right-angled trapezoidal platform-shaped lower base 501. The right-angled trapezoidal platform-shaped lower base 501 is fitted with two rectangular vertical side end surfaces of the right-angled triangular prism-shaped side base 502, and the right-angled trapezoidal rear end surface of the right-angled trapezoidal platform-shaped lower base 501 and the right-angled triangular rear end surface of the right-angled triangular prism-shaped side base 502 form a combined contact surface 4 500 (i.e. Fig.11 The front view, Fig.12 The rear view surface) is in contact with the front end surface of the concrete beam four 5, and the right-angled trapezoidal table-shaped lower base five 501 and the right-angled triangular prism-shaped side base 502 are respectively in contact with the upper right and upper left positions of the front end surface of the concrete beam four 5.

[0040] When installing the concrete beam 1 2, concrete beam 2 3, concrete beam 3 4, and concrete beam 4 5, they are installed in sequence, and the beam 1 clamping piece 20, beam 2 clamping piece 30, beam 3 clamping piece 40, and beam 4 clamping piece 50 of the four concrete beams are sequentially clamped during the installation process. Fig.13 As shown, after the beam one engaging piece 20, the beam two engaging piece 30, the beam three engaging piece 40, and the beam four engaging piece 50 are engaged in the beam mounting hole 12, the right-angled trapezoidal terrace-shaped lower base 2 302 is pressed onto the upper end face of the isosceles trapezoidal terrace-shaped lower base 201 on the left side of the right-angled triangular prism-shaped upper base 202; the right-angled trapezoidal terrace-shaped lower base 402 is pressed onto the upper end face of the right-angled trapezoidal terrace-shaped lower base 301 on the left side of the right-angled trapezoidal terrace-shaped lower base 2 302; the right-angled trapezoidal terrace-shaped lower base 5 501 is pressed onto the upper end face of the right-angled trapezoidal terrace-shaped lower base 3 401 on the left side of the right-angled trapezoidal terrace-shaped lower base 4 402, and the inclined side end face of the right-angled triangular prism-shaped side base 502 is pressed onto the inclined side end face of the right-angled triangular prism-shaped upper base 202. Fig.13 In the figure, only the concrete beam 1 2, the concrete beam 3 4 and their respective beam fixing parts, as well as the beam 1 clamping part 20, the beam 2 clamping part 30, the beam 3 clamping part 40, and the beam 4 clamping part 50 are shown. Fig.13 Not shown in .

[0041] like Fig.10 , Fig.13As shown, a smooth transition notch 203 is provided at the upper left corner of the front end of the isosceles trapezoidal lower base 201, and a smooth transition protrusion 303 and a smooth transition protrusion 304 are provided at the right-angled trapezoidal lower base 301, the right-angled trapezoidal lower base 302 and the upper and lower connecting corners with the front end surface of the concrete beam 23, respectively. The smooth transition protrusion 303 fits with the smooth transition notch 203; the right-angled trapezoidal lower base 402 is provided at the lower right corner of the front end. A smooth transition notch 403 is provided, and the smooth transition notch 403 is fitted with a smooth transition protrusion 304; a smooth transition protrusion 3 404 is provided at the upper connecting corner of the right-angled trapezoidal table-shaped lower base 3 401, the right-angled trapezoidal table-shaped lower base 402 and the front end surface of the concrete beam 3 4, and a smooth transition notch 3 503 is provided at the lower right corner of the front end of the right-angled trapezoidal table-shaped lower base 5 501, and the smooth transition protrusion 3 404 is fitted with the smooth transition notch 3 503.

[0042] Among them, the rounded transition protrusion 1 303, the rounded transition protrusion 2 304, the rounded transition notch 2 403, and the rounded transition protrusion 3 404 are all triangular pyramid structures, and the hypotenuse (bc) of the bottom triangle is an arc-shaped side that is concave inward. Taking the setting of the rounded transition protrusion 1 303 as an example, the front corner of the connection between the right-angled trapezoidal table-shaped lower base 1 301 and the right-angled trapezoidal table-shaped lower base 2 302 (i.e., away from the combined contact surface 2 300) coincides with the vertex d of the rounded transition protrusion 1 303; the rear corner of the connection between the right-angled trapezoidal table-shaped lower base 1 301 and the right-angled trapezoidal table-shaped lower base 2 302 (i.e., the connection with the combined contact surface 2 300) coincides with the vertex d of the rounded transition protrusion 1 303. The right angle end point a of the bottom end face of the smooth transition protrusion 1 303 coincides; the right angle side (ab) of the smooth transition protrusion 1 303 coincides with the upper bottom side (i.e., the lower bottom side after inversion) of the right angle trapezoidal rear end face of the right angle trapezoidal table-shaped lower base 2 302; the right angle side (ac) of the smooth transition protrusion 1 303 coincides with the lower bottom side (i.e., the upper bottom side after inversion) of the right angle trapezoidal rear end face of the right angle trapezoidal table-shaped lower base 1 301. The other smooth transition protrusion 2 304, smooth transition notch 2 403, and smooth transition protrusion 3 404 are all arranged in their respective positions in the same manner.

[0043] When the beam one clamping piece 20, the beam two clamping piece 30, the beam three clamping piece 40, and the beam four clamping piece 50 are engaged, these mutually fitting smooth transition protrusions and smooth transition notches can facilitate the mutual engagement between the beam one clamping piece 20, the beam two clamping piece 30, the beam three clamping piece 40, and the beam four clamping piece 50; at the same time, in situations such as earthquakes, the movement of the four concrete beams in the beam mounting holes 12 is facilitated and their vibration energy is reduced during the movement.

[0044] like Figure 1 , Figure 2As shown, vertical limiting through holes 23 are provided on concrete beam 1 2, concrete beam 2 3, concrete beam 3 4, and concrete beam 4 5. Steel plate rubber shock-absorbing pads 6 are provided on the upper end faces of the concrete beams, and the front ends of the steel plate rubber shock-absorbing pads 6 are installed in the blind holes 123 of the column outer wall provided on the side end faces of the precast concrete column 1. A U-shaped fixing piece 7 is provided on the outer side of the precast concrete column 1 above the steel plate rubber shock-absorbing pad 6. The U-shaped fixing piece 7 is tightly attached to the four outer walls of the precast concrete column 1, and vertical bolt fixing holes are provided on the U-shaped fixing piece 7, the steel plate rubber shock-absorbing pad 6, and the trapezoidal precast corbel 11 above and below the limiting through holes 23; high-strength bolts 13 are sequentially passed through the bolt fixing holes of the U-shaped fixing piece 7, the bolt fixing holes of the steel plate rubber shock-absorbing pad 6, the limiting through holes 23 of concrete beam 1 2 or concrete beam 2 3 or concrete beam 3 4 or concrete beam 4 5, and the bolt fixing holes of the trapezoidal precast corbel 11, and fixed. Meanwhile, the steel plate rubber shock-absorbing pad 6 is formed by alternating multiple layers of steel plates and rubber layers and has a certain elasticity.

[0045] In the case of earthquakes, the four concrete beams are subjected to vibrations in multiple directions in turn. During the vibration process, since the diameter of the limiting through hole 23 is larger than the diameter of the high-strength bolt 13, the fixed high-strength bolt 13 does not affect the movement of the concrete beam within a certain range. The concrete beam can move a certain amount in the beam mounting hole 12. At the same time, the right-angled trapezoidal table-shaped fixing piece 21 and the right-angled triangular prism-shaped fixing piece 22 of the concrete beam will deviate from the beam mounting hole 12, but under the self-gravity of the concrete beam and the limiting effect of the steel plate rubber shock-absorbing pad 6, as well as the mutual bite force of other concrete beams, they will return to their original positions. Moreover, the concrete beam will reduce its vibration energy during the movement, improving the earthquake resistance effect.

[0046] The special-shaped assembled frame beam-column node of the present invention is provided with mutually interpenetrating beam mounting holes 12 at the intersection of the four side end faces of the precast concrete column 1 and the upper end face of its trapezoidal precast corbel 11, and special-shaped beam fixing parts and beam clamping parts are provided at the front ends of the four concrete beams. The beam-column node is locked by the mutual clamping of the beam clamping parts at the front ends of the four concrete beams in the beam mounting holes 12; at the same time, the steel plate rubber shock-absorbing pad 6 and the U-shaped fixing part 7 are provided on the concrete beam, and the beam-column is limited and fixed by using high-strength bolts 13.

[0047] The special-shaped assembled frame beam-column node of the present invention has a compact structure and is easy and quick to install. It improves the structural strength of the beam-column connection, reduces the bearing capacity of high-strength bolts, and also improves the integrity and coordination of the beams and columns. It has good seismic effect, high comprehensive strength, and strong practicality.

[0048] The above is an exemplary description of the invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
