[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides an assembled concrete structure connection node as Figures 1-5 shown, including a fixing plate 1. Slots 2 are opened on both sides of the fixing plate 1. An insertion plate 3 is inserted into the inside of the slot 2. A connection plate 4 is arranged on the outside of the insertion plate 3. Connection blocks 5 are fixedly arranged at both ends of the connection plate 4. The connection blocks 5 are movably connected to one end of the insertion plate 3 through a pin shaft. A precast concrete wall 6 is arranged on the outside of the connection plate 4. Two groups of precast concrete walls 6 can be mutually attached and spliced;

[0024] Specifically, a movable plate 7 is arranged on the outer side of the fixed plate 1. At the four corners of the outer side wall of the movable plate 7, movable arms 8 are movably arranged through pin shafts. One end of each movable arm 8 is movably connected to the outer side wall of the insertion plate 3 through a pin shaft. A through hole 9 is arranged through the middle of the movable plate 7. A positioning bolt 10 is arranged through the inside of the through hole 9, and one end of the positioning bolt 10 is fixedly arranged on the outer side of the fixed plate 1. A positioning nut 11 is sleeved on one end of the positioning bolt 10, and the positioning nut 11 is arranged on the outer side of the movable plate 7. The positioning nut 11 presses the movable plate 7, and the movable plate 7 drives the insertion plate 3 to move through the movable arms 8, so that the insertion plate 3 moves towards the outside of the insertion slot 2. The insertion plate 3 drives the connecting plate 4 to move, and the position adjustment of the insertion plate 3 and the connecting plate 4 can be realized;

[0025] More specifically, through grooves 12 are arranged through both ends of the outer side surface of the fixed plate 1. A support bolt 13 is arranged through the inside of the through groove 12. A support seat 14 is fixedly arranged at one end of the support bolt 13. Fixed seats 15 are movably arranged on both sides of the support seat 14 through pin shafts. An adjusting nut 16 is sleeved on the other end of the support bolt 13, and the adjusting nut 16 is arranged on the outer side of the fixed plate 1. An installation hole is arranged through the middle of the fixed seat 15. The two fixed seats 15 are respectively fixedly arranged on the outer side surfaces of the two precast concrete walls 6 through bolts;

[0026] And, an extension seat 17 is fixedly arranged at the top end of the outer side surface of the fixed plate 1. An insertion block 18 is fixedly arranged on the upper surface of the extension seat 17. A connection frame 19 corresponding to the insertion block 18 is fixedly arranged at the bottom end of the outer side surface of the fixed plate 1. The connection frame 19 cooperates with the insertion block 18, which facilitates the connection between the upper and lower groups of fixed plates 1;

[0027] Moreover, connection ears 20 are fixedly arranged at the four corners of the outer side wall of the connecting plate 4, and the connection ears 20 are fixedly connected to the outer side surface of the precast concrete wall 6 through bolts. The connecting plate 4 can be fixed on the surface of the precast concrete wall 6 through the connection ears 20 to improve the connection stability between the device and the precast concrete wall 6.

[0028] The working principle of the utility model:

[0029] When installing this device, first insert the support bolt 13 into the through groove 12, and then move the fixed plate 1, so that the fixed plate 1 drives the support bolt 13 to move, and the support bolt 13 drives the support seat 14 to move, so that the support seat 14 moves to the connection of the two precast concrete walls 6. At this time, use fasteners such as expansion bolts to connect the two fixing seats 15 on both sides of the support seat 14 to the two precast concrete walls 6 respectively. Then rotate the positioning nut 11, so that the positioning nut 11 squeezes the movable plate 7, and the movable plate 7 drives the plug plate 3 to move through the movable arm 8, so that the plug plate 3 moves towards the outside of the slot 2. The plug plate 3 drives the connecting plate 4 to move until the two connecting plates 4 are respectively attached to the surfaces of the two precast concrete walls 6. At this time, rotate the adjusting nut 16, so that the adjusting nut 16 squeezes the fixed plate 1, so that the fixed plate 1 drives the plug plate 3 to move towards the connection of the precast concrete wall 6. At this time, the connection between the device and the precast concrete wall 6 can be realized;

[0030] After the device is installed, mortar or concrete can be poured into the inner side of the fixed plate 1, so that the triangular area between the fixed plate 1, the plug plate 3 and the precast concrete wall 6 is poured to form a concrete area, which improves the assembly stability of the precast concrete wall 6 and the sealing performance of the connection at the same time. Before pouring, the gap between the fixed plate 1 and the plug plate 3 can be filled with sealant. When it is inconvenient to carry out pouring operations, the connection of the precast concrete wall 6 can be directly blocked with sealant, which can also achieve the effect of improving the sealing performance.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
