Under seismic loads, the joints of double-T slab floor systems are relatively weak points, and the reliability of the joint connections directly affects the overall performance of the floor system and the seismic performance of the overall building structure. Existing technologies include various double-T slab connection structures.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-6The present invention provides a technical solution: a double T-plate connection structure, including a double T-plate 1, a first connection mechanism is installed on one side wall of the double T-plate 1, a second connection mechanism is installed on the other side wall of the double T-plate 1, and the first connection mechanism and the second connection mechanism are fixed by a first fixing mechanism. The first connection mechanism and the second connection mechanism are both fixed inside the double T-plate 1 by the second fixing mechanism, and an anti-vibration mechanism is installed on the upper wall of the second fixing mechanism.

[0021] During the casting of the double-T slab 1, a pair of first rectangular fixing blocks 2 are placed inside. At this time, the outer wall of the first rectangular fixing block 2 is fitted with a rectangular plate 4 and two pairs of triangular fixing blocks 3, so that the first rectangular fixing blocks 2 are more firmly attached to the inside of the double-T slab 1 during solidification. During installation, since the convex barrel 5 is installed inside the first rectangular fixing block 2, when connecting a pair of double-T slabs 1, the pair of first rectangular fixing blocks 2 are placed correspondingly. At this time, the convex barrel 5 inside the first rectangular fixing block 2 is inserted into the other first rectangular fixing block 2 by moving it. When the convex barrel 5 expands and contracts to a certain extent and meets the connection length, the first rectangular fixing block 2 and the convex barrel 5 are fixed by fastening bolts. When connecting the convex barrel 5 to the other first rectangular fixing block 2, the convex barrel 5 is inserted into the other first rectangular fixing block 2 through the first rectangular plate 4 on the lower wall of the convex barrel 5. The groove is fixed on the second rectangular fixing block inside the first rectangular fixing block 2. At this time, a pair of T-shaped rods 6 are placed inside the cross groove inside the convex barrel 5. The rod ends of the convex barrel 5 are exposed through the circular through hole on the upper wall of the first rectangular fixing block 2. Then, with the help of external equipment, the first nut 7 and the second nut 8 are screwed and fixed inside the convex barrel 5 and outside the other first rectangular fixing block 2, respectively, so as to fix them more firmly. After the connection is completed, it can be filled with cement or other building materials. In order to prevent damage to the connection during use, the damper 15 and the telescopic rod 16 between the first box 10 and the first box cover 9 can be used to buffer the force, so that the force on the upper wall of the first rectangular fixing block 2 is buffered by the linkage between the telescopic rod 16, the second rod 14, the first rod 13 and the second rod 14 and the damper 15, thereby reducing the impact of external force on the connection.

A plurality of first circular through holes are opened on the outer wall of a pair of first rectangular fixing blocks 2.

[0023] When the double T plate 1 is poured, a pair of first rectangular fixing blocks 2 are placed inside. At this time, the outer wall of the first rectangular fixing block 2 is fitted with a rectangular plate body 4 and two pairs of triangular fixing blocks 3, so that the first rectangular fixing block 2 is more firmly attached to the inside of the double T plate 1 during solidification.

[0024] Furthermore, the first connecting mechanism includes a second rectangular fixing block, and a pair of the second rectangular fixing blocks are respectively installed on the lower inner wall of the first rectangular fixing block 2.

[0025] The convex barrel 5 is inserted into another first rectangular fixing block 2 and fixed on the second rectangular fixing block inside the first rectangular fixing block 2 through the first rectangular groove on the lower wall of the convex barrel 5.

[0026] Furthermore, the second connecting mechanism includes a convex barrel 5, the lower wall of which has a pair of first rectangular grooves, the inner lower wall of which has a cross groove, and the upper wall of which has a pair of rectangular through holes. The cross-section of the convex barrel 5 is convex, and the convex barrel 5 is installed inside the first rectangular fixing block 2. The pair of first rectangular grooves on the lower wall of the convex barrel 5 are fitted onto the pair of rectangular fixing blocks on the lower inner wall of the first rectangular fixing block 2. Several fastening bolts are inserted between the first rectangular fixing block 2 and the convex barrel 5, and the fastening bolts are located inside the circular through holes of the first rectangular fixing block 2.

[0027] The convex barrel 5 is inserted into another first rectangular fixing block 2 and fixed on the second rectangular fixing block inside the first rectangular fixing block 2 through the first rectangular groove on the lower wall of the convex barrel 5.

[0028] Furthermore, the first fixing mechanism includes a T-shaped rod 6, the T-shaped end of which is rectangular and inserted into the cross groove of the convex barrel 5. The rod end of the T-shaped rod 6 is divided into two ends, and the two ends are provided with opposite threaded grooves. The opposite threaded groove ends of the T-shaped rod 6 are respectively fitted with a second nut 8 and a first nut 7.

[0029] Place a pair of T-shaped rods 6 inside the cross groove inside the convex barrel 5. Expose the rod ends of the convex barrel 5 through the circular through hole on the upper wall of the first rectangular fixing block 2. Then, with the help of external equipment, screw the first nut 7 and the second nut 8 into the convex barrel 5 and the other first rectangular fixing block 2 respectively to fix them more firmly.

[0030] Furthermore, the seismic anti-seismic mechanism includes a first housing 10, which is mounted on the upper wall of the first rectangular fixing block 2. A first housing cover 9 is fitted onto the upper wall of the first housing 10. A first right-angled trapezoidal fixing block 11 and a second right-angled trapezoidal fixing block 12 are respectively mounted on the upper inner wall of the first housing cover 9 and the lower inner wall of the first housing 10. A second rod 14 and a first rod 13 are respectively hinged to one end of the first right-angled trapezoidal fixing block 11 and the second right-angled trapezoidal fixing block 12. A damper 15 is mounted on the other end of the first rod 13. A third rod 17 is mounted on the other end of the damper 15. A telescopic rod 16 is mounted on the other end of the third rod 17. A spring 18 is installed inside the telescopic rod 16. The other end of the second rod 14 is mounted on the side wall of the other end of the telescopic rod 16.

[0031] To prevent damage to the connection, the damping force of the damper 15 and the telescopic rod 16 between the first housing 10 and the first housing cover 9 can be buffered, thereby reducing the impact of external forces on the connection.

[0032] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0033] Example: During the casting of the double-T slab 1, a pair of first rectangular fixing blocks 2 are placed inside. At this time, the outer wall of the first rectangular fixing block 2 is fitted with a rectangular plate 4 and two pairs of triangular fixing blocks 3, thus making the first rectangular fixing blocks 2 more firmly attached to the inside of the double-T slab 1 during solidification. During installation, because the convex barrel 5 is installed inside the first rectangular fixing block 2, when connecting a pair of double-T slabs 1, the pair of first rectangular fixing blocks 2 are placed correspondingly. The convex barrel 5 inside the first rectangular fixing block 2 is inserted into the other first rectangular fixing block 2. When the convex barrel 5 expands or contracts to a certain extent and meets the connection length, the first rectangular fixing block 2 and the convex barrel 5 are fixed together by fastening bolts. When connecting the convex barrel 5 to the other first rectangular fixing block 2, the convex barrel 5 is inserted into the other first rectangular fixing block 2 through the first... A rectangular groove is fixed on the rectangular fixing block inside the first rectangular fixing block 2. At this time, a pair of T-shaped rods 6 are placed inside the cross groove inside the convex barrel 5. The rod ends of the convex barrel 5 are exposed through the circular through hole on the upper wall of the first rectangular fixing block 2. Then, with the help of external equipment, the first nut 7 and the second nut 8 are screwed and fixed inside the convex barrel 5 and outside the other first rectangular fixing block 2, respectively, so as to fix them more firmly. After the connection is completed, it can be filled with cement or other building materials. In order to prevent damage to the connection during use, the damper 15 and the telescopic rod 16 between the first box 10 and the first box cover 9 can be used to buffer the force. Thus, the force on the upper wall of the first rectangular fixing block 2 is buffered by the linkage between the telescopic rod 16, the second rod 14, the first rod 13 and the second rod 14 and the damper 15, thereby reducing the impact of external force on the connection.
