Description

Technical Field

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

[0002] PC prefabricated components are the core components of prefabricated buildings. They refer to concrete components that are precast in the factory and then transported to the construction site through mechanical lifting, connection and assembly to form the entire building. PC prefabricated components include prefabricated wall panels, such as load-bearing walls, exterior wall panels and interior wall panels. The prefabrication process usually requires steel bar processing, concrete pouring and surface treatment. However, this treatment method usually has the following problems:

[0003] First, for the bending and placement of steel bars in PC prefabricated components, it is necessary to place steel bars of different shapes in corresponding steel or aluminum molds, and then pour the mixed concrete into the corresponding molds. This can enhance the strength of the concrete. However, traditional pouring often causes continuous impact on the steel bars placed in the steel or aluminum molds, which in turn causes the originally properly placed steel bars to be overturned by the impact, ultimately leading to casting failure.

[0004] Secondly, some prefabricated exterior wall panels are not in a vertical state, but in an inclined state, that is, the bottom surface is horizontal and the side walls are inclined. However, the internal steel bars are in an inclined state. For prefabricated exterior wall panels with different inclined states, the inclination angle of the internal reinforcement rib assembly also needs to be adjusted accordingly, so that the internal reinforcement rib assembly has the same distance from the molds on both sides. However, the existing technology does not make adjustments for this inclined state, so that the reinforcement rib assembly is located in the middle position of the prefabricated exterior wall panel.

[0005] To this end, we designed a PC prefabricated component for assembled buildings. Summary of the Invention

[0006] The purpose of the present invention is to solve the problem that in the process of producing prefabricated exterior wall panels with horizontal bottom surfaces and inclined side walls, the existing technology does not make adjustments for this inclined state to allow the reinforcement rib assembly to be located in the middle position of the prefabricated exterior wall panels, and proposes a PC prefabricated component for assembled buildings.

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 provided 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 and lowered along the sliding rod. 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 provided on both sides of the flip side mold plate 1, and a hard rubber pad 7 is provided 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 concrete pouring process.

[0037] Furthermore, the two vertical side panels 6 form a closed space with the bottom frame 2, the top frame 3 and the two flip side mold plates 1 in the form of a frame. It should be noted that material holes are provided on the bottom frame 2 and the top frame 3. In this solution, 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 reinforcement 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 tighten the fastening bolts 9, 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 sliding grooves at opposite ends, and the upper and lower ends of the flip side mold plate 1 slide in the sliding grooves through the pushing frame 4, so the sliding grooves provide space for the pushing 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 In the state, 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 at the same time 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 rod, which can prevent the rigid rod from being exposed on the surface of the prefabricated exterior wall panel during the pouring process. The cement solidification blocks 14 can effectively cover the two ends of the rigid rod. After the pouring and solidification are completed, the prefabricated exterior wall panel 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 pusher plate assemblies 15 that are against the reinforcing rib assembly 13, and the pusher plate assembly 15 corresponds to the position of the cement solidification block 14 one by one. The pusher plate assembly 15 is set in multiple groups, and the pusher plate assemblies 15 arranged at the opposite ends of the groove walls of the bottom frame 2 and the top frame 3 slide grooves are 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 pusher assembly. It should be noted that this arrangement ensures that the pusher plate assembly 15 is symmetrically against the two sides of the cement solidification block 14, respectively, and thus can 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 pusher plate assembly 15. The specific two state change processes are as follows:

[0043] First, the pushing 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 slides telescopically 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 threaded 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] The pushing bolt 5 can adopt multiple settings, which can push the pushing bolt 5 on the bottom frame 2 and the top frame 3 to rotate, and can drive the pushing frame 4 to slide together, providing a stable propulsion force for the pushing frame 4 to slide on the slide groove. Furthermore, a driving gear is installed on the pushing bolt 5, and a rack that is meshed with multiple driving gears is provided on the bottom frame 2 and the top frame 3. Therefore, under the action of the external pushing device, the rack can be pushed to move, thereby driving the meshing driving gear to rotate together, and finally driving multiple pushing bolts 5 to rotate together, which can drive the pushing frame 4 to move together.

[0046] Reference Figure 7 State, wherein the upper and lower ends of the flip side mold plate 1 are provided with a rotating shaft 11, and the flip side mold plate 1 is rotatably connected to the propulsion frame 4 through the shaft groove 12. Therefore, in the process of the propulsion bolt 5 pushing the propulsion frame 4 to move, the flip side mold plate 1 changes the position of the flip side mold plate 1 through the rotation of the rotating shaft 11 on the shaft groove 12, so the distance between the two flip side mold plates 1 can be changed by the propulsion bolt 5.

[0047] It should be noted that the balanced propulsion assembly also includes multiple balance springs 19, and the balance springs 19 are arranged in the built-in cavity 16. The propulsion plate assembly 15 is offset by the reinforcing rib assembly 13 through the balance springs 19, so the two sides of the reinforcing rib assembly 13 are subjected to the same spring extrusion force, which makes the reinforcing rib assembly 13 located in the middle position of the two propulsion frames 4, and the spring coefficients of the multiple balance springs 19 are consistent, so the propulsion plate assembly 15 exerts the same force on the cement solidification block 14 through the balance springs 19. If the propulsion frame 4 on one side moves, this will cause the multiple balance springs 19 on both sides of the reinforcing rib assembly 13 to be inconsistent in force, that is, the position of the cement solidification block 14 at this time is not in the middle position of the two propulsion frames 4, so the balance in this state is broken, and the forces on both sides of the cement solidification block 14 are uneven, so the cement solidification block 14 moves and moves back to the middle position of the propulsion frame 4. After the movement, the forces on the balance springs 19 on both sides of the cement solidification block 14 in the new position are consistent and stop moving.

[0048] Therefore, the flip side mold plates 1 symmetrically arranged on the bottom frame 2 and the top frame 3 move synchronously and symmetrically. At this time, the two flip side mold plates 1 are symmetrically arranged on both sides of the reinforcement rib assembly 13, and the distance from the reinforcement rib assembly 13 to the flip side mold plates 1 on both sides is the same.

[0049] In this state, both sides of the cast prefabricated exterior wall panel 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.

[0050] Second: the push plate assembly 15 pushes the reinforcement rib assembly 13 with the cement solidification block 14 to flip over, refer to Figure 8 state, thereby allowing the reinforcing rib assembly 13 to flip along with the flip side mold 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 lines are a comparison of the states of the reinforcing bar assembly 13 with the cement solidification block 14 and one of the flip side mold plates 1 after flipping.

[0052] Reference Figure 10 and Figure 12 In this state, the propulsion 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 up and down, the propulsion switching assembly is arranged at the end of the propulsion bolt 5, and the propulsion switching assembly is against the propulsion plate assembly 15, and the propulsion switching assembly includes a first end plate 17 and a second end plate 18, and 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, and 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 propulsion 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 provide driving force for the propulsion plate assembly 15 through the first end plate 17 and the second end plate 18.

[0053] The propulsion frame 4 is also provided with a propulsion switching component, which propels the reinforcement rib component 13 to flip and tilt between the two flip side mold plates 1. The propulsion switching component also includes a semicircular ring hole 21, and the semicircular ring hole 21 is opened on the propulsion frame 4. A toggle rod 23 is movable in the semicircular ring hole 21. The end of the propulsion bolt 5 is provided with an end tube 22, and the end tube 22 is provided with a rotating plate 24 that is opposed to the first end plate 17 and the second end plate 18. The rotating plate 24 is connected to the end tube 22 by a connecting rod 25, and the toggle rod 23 is connected to the end tube 22. Therefore, when the first end plate 17 and the second end plate 18 need to be further pushed to make the upper push plate 151 and the lower push plate 152 misaligned, it is only necessary to toggle the toggle rod 23 in the semicircular ring hole 21, thereby driving the rotating plate 24 on the end tube 22 to rotate. Figure 12 State, in this state, the rotating plate 24 can push the first end plate 17 and the second end plate 18 to rotate together. After the toggle lever 23 is rotated, the toggle lever 23 is rotated counterclockwise. Since the connecting rod 25 and the end tube 22 are eccentrically arranged, the rotating plate 24 will be separated from the second end plate 18 and only contact the first end plate 17. Then, the push bolt 5 is rotated at this time to push the upper push plate 151 on the first end plate 17.

[0054] Similarly, when the toggle rod 23 on the other side of the cement solidification block 14 rotates clockwise, the rotating plate 24 on that side will disengage from the first end plate 17 and only contact the second end plate 18. Then, the push bolt 5 is rotated, which will push the lower push plate 152 on the second end plate 18. Therefore, the cement solidification block 14 located in the middle position between the two push frames 4 will be in a high and low misaligned pushing and squeezing state, thereby causing the cement solidification block 14 to deflect in the vertical direction with the reinforcing rib assembly 13.

[0055] Therefore, the upper push plate 151 and the lower push plate 152 can play the role of separating and dislocating and sliding, so that the push plate assemblies 15 located 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 the cement solidification block 14, so the upper push plate 151 and the lower push plate 152 are in a dislocated state. Furthermore, the push plate assembly 15 is provided with a notch toward one side of the cement solidification block 14, which can better clamp the cement solidification block 14. At the same time, the dislocated movement can drive the cement solidification block 14 to deflect in the vertical direction, thereby driving the reinforcing rib 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 prefabricated exterior wall panel are in an asymmetrically inclined state, but the two ends of the reinforcement rib assembly 13 in the cast prefabricated exterior wall panel are located in the middle position of the upper and lower ends of the cast prefabricated exterior wall panel. Therefore, the reinforcement rib assembly 13 at this time is still in the middle position of the cast prefabricated exterior wall panel, so the distance from the reinforcement rib assembly 13 to the cast prefabricated exterior wall panel with asymmetrically inclined states on both sides is still the same. Therefore, it can play a role in timely adjusting the position of the corresponding reinforcement rib assembly 13 according to the side wall of the cast prefabricated exterior wall panel, so that the distance from the reinforcement rib assembly 13 to the cast prefabricated exterior wall panel is the same, thereby improving the stability of the prefabricated exterior wall panel.

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

[0058] 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, thereby being able to press the top frame 3 to be vertically lifted, providing a horizontal pressing force for the top frame 3.

[0059] First, turn the push bolt 5 so that the rotation of the push bolt 5 can drive the push bolt 5 to rotate in the push frame 4, and then push the push bolt 5 on the bottom frame 2 and the top frame 3 to rotate, and drive the push frame 4 to slide together. The flip side mold plate 1 is changed by rotating the rotating shaft 11 on the shaft groove 12 to change the position of the flip side mold plate 1. Therefore, the distance between the two flip side mold plates 1 can be changed by the push bolt 5, and the flip side mold plates 1 symmetrically arranged on the bottom frame 2 and the top frame 3 move synchronously and symmetrically. At this time, the two flip side mold plates 1 are symmetrically arranged on both sides of the reinforcement rib assembly 13, and the distance from the reinforcement rib assembly 13 to the flip side mold plates 1 on both sides is the same.

[0060] Then, the toggle rod 23 is rotated clockwise and counterclockwise, and the rotating plate 24 will disengage from the second end plate 18 and only contact the first end plate 17. Then, by rotating the push bolt 5 at this time, the upper push plate 151 on the first end plate 17 can be pushed, and the toggle rod 23 on the other side of the cement solidification block 14 is rotated 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, by rotating the push bolt 5, the lower push plate 152 on the second end plate 18 will be pushed. Therefore, the cement solidification block 14 located in the middle position between the two push frames 4 will be in a high and low misaligned pushing and squeezing state, thereby causing the cement solidification block 14 to deflect in the vertical direction with the reinforcing rib assembly 13.

[0061] Therefore, the two sides of the cast prefabricated exterior wall panel are in an asymmetrically inclined state, but the two ends of the reinforcing rib assembly 13 in the cast prefabricated exterior wall panel are located in the middle position of the upper and lower ends of the cast prefabricated exterior wall panel. Therefore, the reinforcing rib assembly 13 at this time is still in the middle position of the cast prefabricated exterior wall panel, so the distance between the reinforcing rib assembly 13 and the cast prefabricated exterior wall panel with asymmetrically inclined states on both sides is still the same. Therefore, it can play a role in timely adjusting the position of the corresponding reinforcing rib assembly 13 according to the side wall of the cast prefabricated exterior wall panel, so that the distance between the reinforcing rib assembly 13 and the cast prefabricated exterior wall panel is the same.

[0062] Finally, the strip holes 8 and the threaded grooves 10 are adapted to be tightened with the fastening bolts 9, and then the entire vertical side plate 6 is pressed against both sides of the flip side mold plate 1 through the fastening bolts 9. Material holes are opened on the bottom frame 2 and the top frame 3. This scheme is to pass concrete into the material holes in the bottom frame 2, and then discharge air from the material holes on the top frame 3, thereby forming an effect of discharging concrete upwards, which can effectively reduce the bubbles inside the prefabricated exterior wall panels formed, which is beneficial to improving the finished product rate of prefabricated exterior wall panels.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
