Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and particularly to a PC prefabricated component for prefabricated buildings. Background Art

[0002] PC prefabricated components are the core components of prefabricated buildings, referring to concrete components precast in factories. After being transported to the construction site, they are assembled into an integral building through mechanical hoisting and connection. PC prefabricated components cover precast wall panels, such as load-bearing walls, exterior wall panels, and interior wall panels, etc. During the process of precasting wall panels, steel bar processing, concrete pouring, and surface treatment are usually required. However, this processing method usually has the following problems:

[0003] First, for the bending and placement of steel bars in PC prefabricated components, steel bars of different shapes need to be placed in corresponding steel molds or aluminum molds, and then the mixed concrete is poured into the corresponding molds. This can enhance the strength of the concrete. However, traditional pouring often continuously impacts the steel bars placed in the steel molds or aluminum molds, resulting in the originally properly placed steel bars being impacted and toppled, ultimately leading to the failure of casting.

[0004] Secondly, some precast exterior wall panels are not in a vertical state but in an inclined state, that is, precast exterior wall panels with a horizontal bottom and inclined side walls. However, the internal steel bars are in an inclined state. For precast exterior wall panels in different inclined states, the inclination angle of the internal reinforcement component also needs to be adjusted correspondingly so that the internal reinforcement component has the same distance from the two side molds. However, in the prior art, there is no adjustment for this inclined state to make the reinforcement component located in the middle position of the precast exterior wall panel.

[0005] Therefore, we have designed a PC prefabricated component for prefabricated buildings. Summary of the Invention

[0006] The purpose of the present invention is to solve the problem that in the prior art, there is no adjustment for the inclined state during the production of precast exterior wall panels with a horizontal bottom and inclined side walls, and to make the reinforcement component located in the middle position of the precast exterior wall panel, and to propose a PC prefabricated component for prefabricated buildings.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

A top frame is provided above the bottom frame. Sliding grooves are formed at opposite ends of the bottom frame and the top frame. The upper and lower ends of the flipping side die plates slide in the sliding grooves through a propulsion frame. A reinforcing rib assembly is arranged between the two flipping side die plates. Propulsion plate assemblies for abutting against the reinforcing rib assembly are arranged at opposite ends of the groove walls of the sliding grooves of the bottom frame and the top frame. The reinforcing rib assembly vertically moves between the two flipping side die plates through a balance propulsion assembly. A propulsion switching assembly is further arranged on the propulsion frame, and the propulsion switching assembly propels the reinforcing rib assembly to flip and incline between the two flipping side die plates.

[0009] Preferably, a buffer pad is arranged on one side of the propulsion frame facing the sliding groove. Propulsion bolts penetrating into the sliding groove are provided on both the bottom frame and the top frame, and the propulsion bolts are connected to the propulsion frame. Rotating shafts are arranged at both the upper and lower ends of the flipping side die plate, and the flipping side die plate is rotationally connected to the propulsion frame through a shaft groove.

[0010] Preferably, two vertical side plates are symmetrically arranged on both sides of the flipping side die plate. A hard rubber pad is arranged on one side of the vertical side plate facing the flipping side die plate. Threaded grooves are symmetrically arranged on both sides of the bottom frame and the top frame facing the vertical side plate. A through hole corresponding to the threaded groove is arranged on one side of the vertical side plate facing the bottom frame, and a strip hole adapted to the threaded groove is arranged on one side of the vertical side plate facing the top frame. The vertical side plate abuts against both sides of the flipping side die plate through a fastening bolt.

[0011] Preferably, the reinforcing rib assembly is formed by vertically welding a plurality of rigid rods, and cement solidification blocks are sleeved at both ends of the rigid rods. The vertical plane where the reinforcing rib assembly is located is perpendicular to the bottom frame.

[0012] Preferably, the positions of the propulsion plate assemblies correspond to those of the cement solidification blocks one by one. The propulsion plate assemblies are arranged in multiple groups. The propulsion plate assemblies arranged at opposite ends of the groove walls of the sliding grooves of the bottom frame and the top frame are symmetrically arranged on both sides of the cement solidification block and abut against the outer side wall of the cement solidification block.

[0013] Preferably, the propulsion plate assembly includes an upper propulsion plate and a lower propulsion plate, and the upper propulsion plate and the lower propulsion plate are stacked vertically. The propulsion plate assembly telescopically slides on the bottom frame and the top frame through a sliding hole.

[0014] Preferably, the balance propulsion assembly includes an internal cavity opened in the bottom frame and the top frame. The internal cavity is communicated with the sliding hole, and the propulsion bolt threadedly penetrates into the internal cavity. The propulsion switching assembly is arranged at the end of the propulsion bolt and abuts against the propulsion plate assembly.

[0015] Preferably, the balance propulsion assembly further includes a plurality of balance springs, and the balance springs are arranged in the internal cavity. The propulsion plate assembly abuts against the reinforcing rib assembly through the balance springs.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. In the present invention, material holes are opened on the bottom frame and the top frame. Concrete is introduced through the material hole in the bottom frame, and then air is discharged through the material hole on the top frame. Therefore, an effect of discharging concrete upward is formed, which can effectively reduce the air bubbles inside the formed precast exterior wall panel, beneficial to improving the yield of the precast exterior wall panel. At the same time, due to the propulsion and pressing of the propulsion plate component, the impact displacement of the reinforcement component during the filling process is also avoided.

DETAILED DESCRIPTION

[0035] Reference Figures 1 - 12 A PC prefabricated component for assembled buildings includes a bottom frame 2 and two flip side mold plates 1 symmetrically arranged on the bottom frame 2. A top frame 3 is arranged above the bottom frame 2, so that the bottom frame 2, the top frame 3 and the two flip side mold plates 1 form a frame, wherein an external pressing platform is placed on the top frame 3, wherein the external pressing platform is in a vertical lifting state, and can press the top frame 3 to be vertically lifted, that is, it is arranged parallel to the bottom frame 2. It should be noted that the external pressing platform is a counterweight block that is vertically lifted along the sliding rod, and the external pressing platform only provides a horizontal pressing force for the top frame 3, which will not be elaborated here.

[0036] Two vertical side panels 6 are symmetrically arranged on both sides of the flip side mold plate 1, and a hard rubber pad 7 is arranged on the side of the vertical side panel 6 facing the flip side mold plate 1. Therefore, when the vertical side panels 6 are fitted toward the two sides of the flip side mold plate 1, the hard rubber pad 7 can be tightly attached to the two sides of the flip side mold plate 1. Only in this way can a closed environment be formed to prevent concrete from flowing out of the gap during the pouring of concrete.

[0037] Furthermore, the two vertical side panels 6 form a closed space with the frame-like bottom frame 2, the top frame 3 and the two flip side mold plates 1. It should be noted that material holes are opened on the bottom frame 2 and the top frame 3. In this scheme, concrete is introduced from the material holes in the bottom frame 2, and then the air is discharged from the material holes on the top frame 3, thereby forming an effect of discharging concrete upwards. This can effectively reduce the number of bubbles inside the prefabricated exterior wall panels formed, which is beneficial to improving the yield of prefabricated exterior wall panels. At the same time, due to the tight push of the push plate assembly 15, the impact and displacement of the reinforcing rib assembly 13 during the filling process is also avoided.

[0038] Reference Figure 2 and Figure 3 State, the bottom frame 2 and the top frame 3 are symmetrically provided with thread grooves 10 on one side of the vertical side plate 6, the vertical side plate 6 is provided with a through hole corresponding to the thread groove 10 on the side facing the bottom frame 2, and the vertical side plate 6 is provided with a strip hole 8 adapted to the thread groove 10 on the side facing the top frame 3. The vertical side plate 6 is abutted against the two sides of the flip side mold plate 1 through the fastening bolts 9. Therefore, the fastening bolts 9 are adapted to the through holes and the thread grooves 10 and tightened at the bottom of the vertical side plate 6 to tighten the lower part of the vertical side plate 6 against the two sides of the flip side mold plate 1. Then, since the flip side mold plate 1 is in a flipped state, the distance between the top frame 3 and the bottom frame 2 will continue to change. Therefore, the strip hole 8 and the thread groove 10 are adapted to the fastening bolts 9 and tightened, and then the entire vertical side plate 6 is fastened to the two sides of the flip side mold plate 1 through the fastening bolts 9.

[0039] The bottom frame 2 and the top frame 3 are provided with slide grooves at opposite ends, and the upper and lower ends of the flip side mold plate 1 slide in the slide grooves through the push frame 4, so the slide grooves provide space for the push frame 4 to slide.

[0040] Furthermore, a reinforcing rib assembly 13 is provided between the two flip side mold plates 1, referring to Figure 9 The reinforcing rib assembly 13 is a plurality of rigid rods welded vertically, and the vertical surface where the reinforcing rib assembly 13 is located is perpendicular to the bottom frame 2, wherein the rigid rods are made of basalt fiber or glass fiber to enhance the strength of the reinforcing rib assembly 13 and enhance the rigidity and impact resistance of the cast prefabricated exterior wall panels.

[0041] Cement solidification blocks 14 are provided at both ends of the rigid rods to prevent the rigid rods from being exposed on the surface of the prefabricated exterior wall panels during the pouring process. The cement solidification blocks 14 can effectively cover the two ends of the rigid rods. After the pouring and solidification are completed, the prefabricated exterior wall panels can be further polished to remove burrs.

[0042] Reference Figure 4 and Figure 5 State, the opposite ends of the groove walls of the bottom frame 2 and the top frame 3 slide grooves are provided with a push plate assembly 15 that is against the reinforcing rib assembly 13, and the push plate assembly 15 corresponds to the cement solidification block 14 position one by one. The push plate assembly 15 is set in multiple groups, and the push plate assembly 15 arranged at the opposite ends of the groove walls of the bottom frame 2 and the top frame 3 slide grooves is symmetrically arranged on both sides of the cement solidification block 14 and against the outer wall of the cement solidification block 14. The reinforcing rib assembly 13 moves vertically between the two flip side mold plates 1 through the balanced push assembly. It should be noted that such a setting ensures that the push plate assembly 15 is symmetrically against the two sides of the cement solidification block 14, respectively, so as to push the reinforcing rib assembly 13 with the cement solidification block 14 to move together. Therefore, this scheme pushes the reinforcing rib assembly 13 with the cement solidification block 14 to move and flip in two states according to the push plate assembly 15. The specific two state change processes are as follows:

[0043] First, the push plate assembly 15 pushes the reinforcing rib assembly 13 with the cement solidification block 14 to move horizontally together without rotating, thereby ensuring that the reinforcing rib assembly 13 and the flip side mold plates 1 on both sides are at the same distance.

[0044] Reference Figure 10 and Figure 11 State, the balanced propulsion assembly includes a built-in cavity 16, the built-in cavity 16 is opened in the bottom frame 2 and the top frame 3, the propulsion plate assembly 15 is telescopically slidable on the bottom frame 2 and the top frame 3 through the sliding hole, the built-in cavity 16 is connected to the sliding hole, and the propulsion bolt 5 is threadedly penetrated into the built-in cavity 16. It should be noted that since the bottom frame 2 and the top frame 3 are penetrated by the propulsion bolt 5, and the propulsion bolt 5 is connected to the propulsion frame 4, the propulsion bolt 5 rotates coaxially on the bottom frame 2 and the top frame 3, but does not move, so as the propulsion bolt 5 rotates, it can drive the propulsion bolt 5 to rotate in the propulsion frame 4.

[0045] Among them, multiple propulsion bolts 5 can be provided, which can drive the propulsion bolts 5 on the bottom frame 2 and the top frame 3 to rotate, and can drive the propulsion frame 4 to slide together, providing a stable propulsion force for the propulsion frame 4 to slide on the chute. Further, drive gears are installed on all the propulsion bolts 5, and racks meshing with multiple drive gears are provided on the bottom frame 2 and the top frame 3. Therefore, under the action of an external propulsion device, the rack can be pushed to move, thereby driving the meshing drive gears to rotate together, and finally driving multiple propulsion bolts 5 to rotate together, and then being able to drive the propulsion frame 4 to move together.

[0046] Referring to Figure 7 the state, wherein rotating shafts 11 are provided at both the upper and lower ends of the flipping side die plate 1, and the flipping side die plate 1 is rotatably connected to the propulsion frame 4 through the shaft groove 12. Therefore, during the process of the propulsion bolt 5 pushing the propulsion frame 4 to move, the flipping side die plate 1 rotates on the shaft groove 12 through the rotating shaft 11, thereby changing the position of the flipping side die plate 1. Therefore, the distance between the two flipping side die plates 1 can be changed by the propulsion bolt 5.

[0047] It should be noted that the balance propulsion assembly further includes multiple balance springs 19, and the balance springs 19 are arranged in the built-in cavity 16. The propulsion plate assembly 15 abuts against the reinforcing rib assembly 13 through the balance springs 19. Therefore, the spring extrusion forces received on both sides of the reinforcing rib assembly 13 are the same, so that the reinforcing rib assembly 13 is located in the middle position between the two propulsion frames 4. And the spring coefficients of the multiple balance springs 19 are the same. Therefore, the forces exerted by the propulsion plate assembly 15 on the cement solidification block 14 through the balance springs 19 are the same. If one of the propulsion frames 4 moves, this will cause the forces received by the multiple balance springs 19 on both sides of the reinforcing rib assembly 13 to be inconsistent, that is, the position of the cement solidification block 14 at this time is not in the middle position between the two propulsion frames 4. Therefore, the balance in this state is broken, and the forces on both sides of the cement solidification block 14 are uneven at this time. Therefore, the cement solidification block 14 moves and moves back to the middle position between the propulsion frames 4. After moving, the forces received by the balance springs 19 on both sides of the cement solidification block 14 at the new position are the same, and the movement stops.

[0048] Therefore, the flipping side die plates 1 symmetrically arranged on the bottom frame 2 and the top frame 3 move symmetrically synchronously. At this time, the two flipping side die plates 1 are symmetrically arranged on both sides of the reinforcing rib assembly 13, and the distances from the reinforcing rib assembly 13 to the flipping side die plates 1 on both sides are the same.

[0049] In this state, the two sides of the precast exterior wall panel formed by casting are in a symmetrically inclined state or a vertical state, and the reinforcing rib assembly 13 with the cement solidification block 14 is in a vertical state at this time.

[0050] Second: The propulsion plate assembly 15 pushes the reinforcing rib assembly 13 with the cement solidification block 14 to flip, referring toFigure 8 The state causes the reinforcing rib assembly 13 to flip together with the flipping side die plate 1 on one side. At this time, the reinforcing rib assembly 13 with the cement solidification block 14 is in an inclined state.

[0051] Figure 8 The dotted line shown is the state comparison after the flipping of the reinforcing rib assembly 13 with the cement solidification block 14 and one of the flipping side die plates 1.

[0052] Refer to Figure 10 and Figure 12 In the state, the push plate assembly 15 includes an upper push plate 151 and a lower push plate 152, and the upper push plate 151 and the lower push plate 152 are stacked vertically. The push switching assembly is arranged at the end of the push bolt 5. The push switching assembly abuts against the push plate assembly 15. The push switching assembly includes a first end plate 17 and a second end plate 18. The first end plate 17 and the second end plate 18 are respectively arranged at the ends of the upper push plate 151 and the lower push plate 152. One end of the balance spring 19 is connected to the inner wall of the built-in cavity 16, and the other end is connected to the push switching assembly. Therefore, when the upper push plate 151 and the lower push plate 152 do not move out of position, the balance springs 19 on the first end plate 17 and the second end plate 18 both provide a driving force for the push plate assembly 15 through the first end plate 17 and the second end plate 18.

[0053] The push switching assembly is also provided on the push frame 4. The push switching assembly pushes the reinforcing rib assembly 13 to flip and incline between the two flipping side die plates 1. The push switching assembly also includes a semi-circular ring hole 21, and the semi-circular ring hole 21 is opened on the push frame 4. A toggle rod 23 is movable in the semi-circular ring hole 21. An end cylinder 22 is provided at the end of the push bolt 5, and a rotating plate 24 that abuts is provided on the side of the end cylinder 22 facing the first end plate 17 and the second end plate 18. The rotating plate 24 is connected to the end cylinder 22 through a connecting rod 25, and the toggle rod 23 is connected to the end cylinder 22. Therefore, when it is necessary to further push the first end plate 17 and the second end plate 18 to cause the upper push plate 151 and the lower push plate 152 to move out of position, only the toggle rod 23 in the semi-circular ring hole 21 needs to be toggled, thereby driving the rotating plate 24 on the end cylinder 22 to rotate. As in Figure 12 In the state, at this time, the rotating plate 24 can push the first end plate 17 and the second end plate 18 to rotate together. After rotating the toggle rod 23 and causing the toggle rod 23 to rotate counterclockwise, since the connecting rod 25 and the end cylinder 22 are eccentrically arranged, the rotating plate 24 at this time will disengage from the second end plate 18 and only contact the first end plate 17. Then, when the push bolt 5 is rotated at this time, the upper push plate 151 on the first end plate 17 can be pushed;

[0054] Similarly, the toggle rod 23 on the other side of the cement solidification block 14 rotates clockwise, and the rotating plate 24 on this side will disengage from the first end plate 17 and only contact the second end plate 18. Then, when the propulsion bolt 5 is rotated, the push plate 152 on the second end plate 18 will be pushed. Therefore, the cement solidification block 14 located at the middle position between the two propulsion frames 4 will be in a state of extrusion with high-low dislocation pushing, and then the cement solidification block 14 will drive the reinforcing bar assembly 13 to deflect in the vertical direction.

[0055] Therefore, the upper push plate 151 and the lower push plate 152 can play a role in separating and sliding in a dislocation manner, so that the propulsion plate assemblies 15 on both sides of the cement solidification block 14 are separated and dislocated. That is, the upper push plate 151 on one side of the cement solidification block 14 pushes and squeezes the cement solidification block 14, while the lower push plate 152 on the other side of the cement solidification block 14 pushes and squeezes the cement solidification block 14. Therefore, the upper push plate 151 and the lower push plate 152 are in a dislocated state. Further, the propulsion plate assembly 15 is provided with a notch on the side facing the cement solidification block 14, which can better hold the cement solidification block 14. At the same time, the dislocated movement can drive the cement solidification block 14 to deflect in the vertical plane direction, and then can drive the reinforcing bar assembly 13 on the cement solidification block 14 to deflect together.

[0056] It should be noted that: in this state, the two sides of the cast precast exterior wall panel are in an asymmetric inclined state, but the two ends of the reinforcing bar assembly 13 in the cast precast exterior wall panel are located at the middle positions of the upper and lower ends of the cast precast exterior wall panel. Therefore, at this time, the reinforcing bar assembly 13 is still in the middle position of the cast precast exterior wall panel. So, at this time, the distances from the reinforcing bar assembly 13 to the two sides of the cast precast exterior wall panel in an asymmetric inclined state are still the same. Therefore, it can timely adjust the position of the corresponding reinforcing bar assembly 13 according to the side wall of the cast precast exterior wall panel, make the distances from the reinforcing bar assembly 13 to the cast precast exterior wall panel the same, and improve the stability of the precast exterior wall panel.

[0057] The working principle of the present invention is as follows:

[0058] Among them, the bottom frame 2, the top frame 3 and the two flipping side die plates 1 enclose a frame body. Among them, an external pressing table is placed on the top frame 3, and the external pressing table is in a vertical lifting state, and then it can press the top frame 3 to be vertically lifted, providing a horizontal pressing force for the top frame 3.

[0059] First, rotate the propulsion bolt 5. The rotation of the propulsion bolt 5 can drive the propulsion bolt 5 to rotate within the propulsion frame 4, and further drive the propulsion bolts 5 on the bottom frame 2 and the top frame 3 to rotate, which can drive the propulsion frame 4 to slide together. The flipping side die plate 1 changes its position by rotating on the shaft groove 12 through the rotating shaft 11. Therefore, the distance between the two flipping side die plates 1 can be changed by the propulsion bolt 5. The symmetrically arranged flipping side die plates 1 on the bottom frame 2 and the top frame 3 move symmetrically and synchronously. At this time, the two flipping side die plates 1 are symmetrically arranged on both sides of the reinforcing rib assembly 13, and the distances from the reinforcing rib assembly 13 to the flipping side die plates 1 on both sides are the same.

[0060] Then, toggle the toggle rod 23 to rotate clockwise and counterclockwise. The rotating plate 24 will disengage from the second end plate 18 and only contact the first end plate 17. Then, rotate the propulsion bolt 5 at this time, which can push the upper push plate 151 on the first end plate 17. While the toggle rod 23 on the other side of the cement solidification block 14 rotates clockwise, the rotating plate 24 on this side will disengage from the first end plate 17 and only contact the second end plate 18. Then, rotate the propulsion bolt 5, which will cause the lower push plate 152 on the second end plate 18 to be pushed. Therefore, the cement solidification block 14 located at the middle position between the two propulsion frames 4 will be in a state of high-low misaligned extrusion, and then the cement solidification block 14 will drive the reinforcing rib assembly 13 to deflect in the vertical direction.

[0061] Therefore, the two sides of the cast-in-place precast exterior wall panel are in an asymmetric inclined state. However, the two ends of the reinforcing rib assembly 13 in the cast-in-place precast exterior wall panel are located at the middle positions of the upper and lower ends of the cast-in-place precast exterior wall panel. Therefore, at this time, the reinforcing rib assembly 13 is still in the middle position of the cast-in-place precast exterior wall panel. So, the distances from the reinforcing rib assembly 13 to the two asymmetrically inclined sides of the cast-in-place precast exterior wall panel are still the same. Therefore, it can timely adjust the position of the corresponding reinforcing rib assembly 13 according to the side wall of the cast-in-place precast exterior wall panel, so that the distances from the reinforcing rib assembly 13 to the cast-in-place precast exterior wall panel are the same.

[0062] Finally, the strip holes 8 and the threaded grooves 10 are adapted and tightened with the fastening bolts 9, and then the entire vertical side plate 6 is tightened against both sides of the flipping side die plate 1 through the fastening bolts 9. The bottom frame 2 and the top frame 3 are provided with material holes. In this solution, concrete is introduced through the material hole in the bottom frame 2, and then air is discharged through the material hole on the top frame 3. Therefore, an effect of discharging concrete upward is formed, which can effectively reduce the air bubbles inside the formed precast exterior wall panel and is beneficial to improving the yield of the precast exterior wall panel.
