[0002] In addition to the foundation, the beam-column structure is the foundation of a building. The load-bearing and earthquake resistance of the entire structure depend on the setting of the beam-column structure. How to quickly set the beam-column structure nodes with a high safety factor is the key to improving the installation speed of the overall structure of the prefabricated building.

[0003] The traditional method of PEC beam-column connection nodes in the prior art is to adopt bolt welding connection, full welding and other connection methods. Since the prior art usually requires welding at the construction site and then pouring between the welded beams and columns, the bearing capacity of the nodes between the beams and columns that have just been welded is poor, affecting the quality of the overall project. In addition, since there are many welding locations, this will result in a long construction period. Therefore, it is necessary to design a topological curled PEC beam end plate body connection structure to solve the above problems. Summary of the invention

The outside gas enters the folding airbag 40 in one direction through the air inlet 41, and the gas in the folding airbag 40 enters the two hollow plates 17 in one direction through the air outlet pipe 18. The right side space of the box body 1 is connected with the bottom space of the water tank 10 through the connecting pipe 12.

[0039] The present invention can explain its functional principle through the following operation mode: a post-casting section is reserved at the end of the topological curled PEC beam body 42 to facilitate the installation of bolts 49. There are casting holes on both sides of the web on the top flange of the post-casting section, and the hole diameter is generally 25-35mm. A steel pipe is welded on the upper part of the hole, and fillet welds are welded around the bottom of the pipe as a sleeve 44 reinforcement to prevent the flange from causing a decrease in bearing capacity and local stress concentration due to the opening of the hole;

[0040] End plate bodies 43 are welded at both ends of the topological curling PEC beam body 42. The flanges and webs of the end plate body 43 and the topological curling PEC beam body 42 are all welded with groove penetration welding. The required number of bolts 49 are arranged on both sides of the upper and lower flanges according to the design force requirements to ensure the spacing and margins of the bolts 49 required by the specification. The size of the end plate body 43 is adjusted to accommodate a sufficient number of bolts 49. High-strength bolts are used for the installation bolts 49.

[0041] The topological curling PEC beam body 42 is installed on the two columns 45. A post-casting section is left between the two columns 45 and the topological curling PEC beam body 42 to facilitate the installation of the bolts 49. Two 90° curved channels (i.e., grouting holes 47) with a diameter greater than 50 mm are reserved in the upper concrete of the post-casting section of the two columns 45. This can be achieved by burying a 90° PVC adapter in the precast concrete after pouring. One of the channels is the grouting port and the other is the grouting outlet. After the high-strength bolts on site are installed, the templates on both sides of the post-casting section are sealed, and concrete is pumped from the grouting hole 47 on the left into the closed post-casting section. The concrete strength is the same as that of the column concrete until it is filled and overflows from the grouting hole 47 on the right, proving that it has been completely filled.

[0042] The post-cast section of the topological curled PEC beam body 42 is pumped with cement-based grouting material or slightly expanding self-compacting mortar from a casing 44. The strength requirements of both must not be lower than the strength of the concrete of the beam component itself. Since the pumped material has high fluidity, it can flow from the 1 / 4 circular welding hole on the web to the other side of the web. When one side of the casing 44 overflows, the node is cast densely.

[0043] After the topological curling PEC beam body 42 and the two end plate bodies 43 are welded, the topological curling PEC beam is hoisted as a whole into the box body 1 using existing hoisting equipment, so that the end plate body 43 located below contacts the support block 13, and then the two pneumatic rods 3 are started to stretch the two pneumatic rods 3, so that the two clamping blocks 4 move relative to each other to clamp the left and right sides of the topological curling PEC beam body 42. At this time, the two pressure sensors 5 generate electrical signals to be transmitted to the controller, and the controller controls the electromagnet 31 to be energized. After the electromagnet 31 is energized, it will generate an attractive force on the moving block 29, so that the moving block 29 moves downward, so that the support block 13 is separated from the end plate body 43;

[0044] Then, the driving motor 36 is started, so that the driving motor 36 drives the first rotating rod 6 on the left side to rotate. Since the four rotating gears 53 are in a meshing state, the remaining three first rotating rods 6 are rotated, and then the multiple abutting rods 7 are rotated;

[0045] When the abutting rod 7 contacts the corresponding pushing rod 22, as the abutting rod 7 rotates, the multiple sliders 21 move away from the corresponding end plate body 43, and the multiple first springs 20 are compressed. When the abutting rod 7 is disengaged, under the elastic action of the multiple first springs 20, the sliders 21 drive the impact balls 24 to approach the corresponding end plate body 43 and impact the end plate body 43. When a large crack is generated between the end plate body 43 and the topological curling PEC beam body 42, it means that the welding between the topological curling PEC beam body 42 and the two end plate bodies 43 is unqualified.

[0046] During the rotation of the driving motor 36, the two vertical rods 16 are driven to rotate through the two bevel gears 37, thereby driving the two second rotating rods 34 to rotate through the transmission assembly 38. At this time, the two disks 33 drive the two rings 25 to rotate, so that multiple CCD visual sensors 26 detect the welding points between the end plate body 43 and the topological curling PEC beam body 42, thereby avoiding the situation where the gap is too small and the staff cannot find it, making the detection of the welding points between the topological curling PEC beam body 42 and the two end plate bodies 43 more accurate;

[0047] During the detection process, the sound insulation cotton 2 can absorb most of the sound generated by the impact. At the same time, the operation of the pump body 9 will cause the water in the water tank 10 to be injected into the atomizing nozzle 14 and sprayed out. At this time, the atomized water can also play a certain noise reduction effect;

[0048] During the rotation of the two vertical rods 16, due to the setting of the threaded layer, the reciprocating block 39 will continuously move up and down, so that the folding airbag 40 will continuously stretch and shrink. When the folding airbag 40 stretches, the external gas will enter the folding airbag 40 through the air inlet 41. When the folding airbag 40 shrinks, the gas in the folding airbag 40 will be injected into the two hollow plates 17 and then sprayed into the box body 1. At this time, the airflow will carry water mist and quickly distribute it in the box body 1. At the same time, excess water mist will enter the water tank 10 with the airflow, so that the water mist can be remixed in the water in the water tank 10.

[0049] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
