Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a large-scale PEC vertical component node structure capable of being cast on site and a coating device thereof. Background Art

[0002] PEC refers to a structural member that is filled with concrete within the outer contour of a steel member (main steel member) in the form of an open section, and can be arranged with longitudinal reinforcement, stirrups, connecting rods, studs and other accessories according to performance requirements. The PEC structure is a composite structure suitable for prefabrication and assembly, which is mainly divided into three major processes: PEC structure manufacturing, reinforcement arrangement and concrete pouring;

[0003] PEC components have reduced the size of concrete cross-sections and component weight through steel skeletons, but for large industrial or public construction projects, larger component sizes are inevitable, which increases the difficulty of on-site lifting. Truck cranes can be used for low-rise buildings, but tower cranes are relatively fixed for high-rise buildings because the lifting weight is related to the component radius. The number of tower cranes needs to be increased or heavier equipment needs to be used, resulting in an exponential increase in lifting costs. At the same time, as vertical components, columns have complex internal node partitions, which are very difficult to cast on site and require partition casting. Therefore, it is necessary to design a large PEC vertical component node structure that can be cast on site to solve the above problems. Summary of the invention

The lower ends of the two vertical plates 29 are provided with vertical grooves, and the inner tops of the two vertical grooves are installed with electromagnets 40. Two movable plates 39 are slidably connected in the two vertical grooves. The rotating shafts of the winding roller 33 and the flattening roller 34 are rotatably connected to the front sides of the corresponding movable plates 39. The power supply, the first touch delay switch 7 and the two electromagnets 40 form a loop through wires. The upper ends of the two movable plates 39 are magnetic. When the electromagnets 40 are energized, they produce a repulsive force on the corresponding movable plates 39.

[0036] Among them, a connecting box 37 is installed on the right side of the vertical plate 29 on the right side, and the vertical groove on the right side is connected with the connecting box 37 through a strip opening 42. A pressure block 38 is slidably connected in the connecting box 37, and a connecting block 43 is fixedly connected between the pressure block 38 and the movable plate 39 on the right side. The connecting block 43 passes through the strip opening 42, and the pressure block 38 and the inner bottom of the connecting box 37 are fixedly connected with a folding airbag 36. A hollow plate 35 is installed at the lower end of the connecting box 37, and a plurality of oblique openings are provided on the right side of the hollow plate 35. The hollow plate 35 is connected with the folding airbag 36 through a connecting pipe.

[0037] The present invention can explain its functional principle through the following operation mode: a vertical stiffening plate 45 is provided in the PEC column body 44, corresponding to the position of the outer corbel splint 46, the corbel splint 46 transmits the bending moment and shear force to the column body through the vertical stiffening plate 45, the length of the corbel splint 46 shall not be less than one times the beam width, the beam flange is welded with the column flange and the three sides of the splint, the welding form is groove penetration welding, the beam web is also welded with the column flange groove penetration welding, the column outer side is attached with a mesh mold 51, the mesh mold 51 can replace the ordinary template, there is a rib on the mesh mold 51 every other section, it can form a certain rigidity, and avoid the template deformation and bulging, there are small grooves on the mesh mold 51, which can secrete excess moisture in the concrete, and the density of the internal concrete can be seen through the groove holes, but the concrete itself will not leak out through the groove due to surface tension, and the mesh mold 51 does not need to be torn off after completion, and its surface is relatively rough, which can improve the adhesion of the paint layer and facilitate later decoration.

[0038] In the process of applying the mesh mold 51, after the stress-bearing longitudinal reinforcement 47 and the C-type tie reinforcement 48 are welded, the two ends of the PEC column body 44 can be placed in the two U-shaped frames 11, and the drive motor 18 can be started to rotate the reciprocating screw 5, so that the slider 26 moves from right to left. During the movement of the slider 26, since the first rack 6 and the second gear 20 are in a meshing state, the vertical rod 27 drives the spiral blade 31 to rotate in the opposite direction, so that the glue in the receiving trough can be continuously transported downward and sprayed on the upper surface of the PEC column body 44;

[0039] When the slider 26 moves to the rightmost position, the first trigger rod 28 contacts the first touch delay switch 7, and the two electromagnets 40 are energized, so that the two electromagnets 40 exert a downward repulsive force on the corresponding moving plate 39, thereby causing the winding roller 33 and the flattening roller 34 to move downward.

[0040] When the movable plate 39 moves downward, the pressing block 38 is driven to move downward, thereby compressing the folding airbag 36, thereby reducing the space in the folding airbag 36 and increasing the air pressure, so that the gas in the folding airbag 36 enters the hollow plate 35 and is ejected through multiple oblique openings. Since the mesh mold 51 is in a naturally drooping state in the initial state, the naturally drooping mesh mold 51 will be offset to the left to the bottom of the flattening roller 34 under the blowing of the airflow. As the flattening roller 34 continues to move downward, the mesh mold 51 is pressed against one side of the PEC column body 44, so that one end of the mesh mold 51 is adhered to the PEC column body 44 by glue.

[0041] When the slider 26 moves to the right, the winding roller 33 rotates, thereby continuously rolling out the mesh mold 51, so that the flattening roller 34 can adhere the mesh mold 51 to the PEC column body 44 in a flat manner;

[0042] When the slider 26 is reset, the infrared sensor 21 senses the distance between the slider 26 and the infrared sensor 21, thereby generating an electrical signal to be transmitted to the controller. The controller controls the solenoid valve on the injection pipe 19 to open for a period of time, so that the glue flows into the receiving trough for replenishment under the action of its own gravity.

[0043] At this time, the control motor needs to be turned off, and the pneumatic rod 15 needs to be controlled to shrink and then reset, so that the second rack 13 drives the PEC column body 44 to flip 180 degrees through the first gear 14, and the two rotating rods 8 rotate 180 degrees;

[0044] Since the two contact rods 9 located at the top are in contact with the corresponding two contact sheets 10 in the initial state, the corresponding two first springs 25 are energized. After the two first springs 25 are energized, each coil generates a magnetic field, and the magnetic fields generated by every two adjacent coils are in opposite directions. Every two adjacent coils attract each other, so that the corresponding two first springs 25 are energized and contracted, and the two stoppers 23 enter the slide groove 24.

[0045] When the two rotating rods 8 rotate, the two contact rods 9 are separated from the corresponding contact pieces 10, and the first spring 25 is powered off, so that the stopper 23 is reset under its own elastic action to prevent the PEC column body 44 from falling off during the rotation process;

[0046] After rotating 180 degrees, the two contact rods 9 located at the bottom contact the corresponding contact pieces 10, the corresponding two first springs 25 are energized and contracted, and the stopper 23 enters the slide groove 24, thereby ensuring that the net mold 51 can be completely laid when it is subsequently laid;

[0047] When the pneumatic rod 15 is retracted to the limit position, the second trigger rod is in contact with the second touch delay switch 17, so that the driving motor 18 repeats the above process again, and then the mesh mold is applied to the other side of the PEC column body 44;

[0048] It is worth mentioning that since a one-way bearing is provided between the first gear 14 and the rotating rod 8, when the pneumatic rod 15 contracts, the moving block 16 moves up and the second rack 13 drives the rotating rod 8 to rotate through the first gear 14. When the pneumatic rod 15 is stretched, the moving block 16 moves down and the second rack 13 drives the first gear 14 to rotate. At this time, the rotating rod 8 will not rotate.

[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.
