Description

Technical Field

[0001] This utility model relates to the technical field of molding product devices, specifically a steel cage positioning device for prefabricated wall panels. Background Technology

[0002] Traditional brick-built partition walls are heavy and thick, and their on-site construction is time-consuming, significantly increasing construction costs. To overcome these problems, lightweight partition walls have gained widespread attention. Lightweight partition walls are constructed from prefabricated wall panels. The assembled wall surface has high flatness, requires no plastering, effectively reduces on-site wet work and dust pollution, and is energy-saving and environmentally friendly. Furthermore, prefabricated wall panels can be pre-produced in factories using assembly lines, ensuring precise dimensions and high-quality curing, effectively shortening construction time and realizing industrialized construction production.

[0003] To increase strength, existing prefabricated wall panels incorporate reinforcing bars inside the mold during the cement slurry pouring process. This increases the strength of the subsequently formed wall panels. In existing technology, prefabricated wall panels are produced using flat molds. The production process involves pouring a layer of cement, laying reinforcing bars, and then pouring another layer of cement to cover the remaining reinforcing bars. Furthermore, the reinforcing bars are mostly laid manually. Utility Model Content

[0004] The present invention aims to provide a rebar cage positioning device for prefabricated wall panels, in order to solve the technical problems of complex rebar laying operation and low production efficiency in the existing technology during the pouring process of prefabricated wall panels, which requires manual intervention.

[0005] This utility model provides the following basic solution:

[0006] A rebar cage positioning device for prefabricated wall panels includes positioning support grooves opened on opposite side plates of the formwork box, and positioning connecting frames that are inserted into the positioning support grooves. There are two positioning connecting frames, and each of the two positioning connecting frames has a connector on its opposite side. The connector is used to position the rebar cage.

[0007] Furthermore, the opening width of the positioning support groove is smaller than the width of the positioning connecting frame in the same direction, and the positioning support groove is used to prevent the positioning connecting frame from coming out of the opening.

[0008] Furthermore, multiple positioning support slots are opened on the same side plate, and the multiple positioning support slots are evenly distributed along the length direction of the side plate; the positioning connecting frame includes multiple support rods, which are inserted into the positioning support slots and correspond one-to-one, and the connecting parts are set on the support rods.

[0009] Furthermore, there are multiple connectors, which are arranged opposite each other to position the same rebar cage.

[0010] Furthermore, the steel cage is provided with connecting ends on both sides, and the connecting ends are detachably connected to the connectors.

[0011] Furthermore, a hollow hole is provided at the end of the connector away from the side plate, and the connector end is inserted into the hollow hole.

[0012] Furthermore, a through hole is provided at the top of the connector, which connects to the opening of the hollow hole and allows the connecting end to pass through.

[0013] Furthermore, the cross-sections of the positioning support groove and the support rod are circular.

[0014] Furthermore, the bottom of the positioning support groove is provided with a guide slope, which slopes from the top to the bottom along the positioning support groove into the mold box.

[0015] Beneficial effects:

[0016] 1. In this solution, when pouring cement slurry into the mold box, the steel cage is placed inside the mold box by positioning and connecting the frame. In the subsequent pouring process, there is no need for multiple pouring, which reduces the cement slurry pouring operation. At the same time, there is no need for manual intervention in laying the steel bars, and there is no need to wait for the steel bars to be laid, which improves production efficiency.

[0017] 2. In this solution, the reinforcing cage is positioned by connectors. The connectors have hollow holes for the connecting ends of the reinforcing cage to be inserted. The reinforcing cage can be positioned and clamped by two connectors, so that the reinforcing cage is kept in the designated position in the formwork box and is not prone to displacement, thereby improving the finished quality of the prefabricated wall panel.

[0018] 3. The opening width of the positioning support groove is smaller than the width of the positioning connecting frame in the same direction. The positioning support groove is used to prevent the positioning connecting frame from coming out of the opening. When closing the mold, the positioning connecting frame is inserted into the positioning support groove from the top of the side plate, thereby placing the rebar cage in the mold box, and then casting is carried out for molding. When opening the mold, the side plate is separated. Since the positioning connecting frame cannot come out of the positioning support groove, the positioning connecting frame separates with the connection end between the side plate and the rebar cage, eliminating the need for a separate disassembly operation and further improving production efficiency.

[0024] Example 1

[0025] A rebar cage positioning device for prefabricated wall panels includes positioning support grooves opened on opposite side plates 7 of the formwork box, and a positioning connecting frame 1 that is inserted into the positioning support grooves, as shown in the attached figure. Figure 1 As shown. The mold box is a molding device required for producing prefabricated wall panels. The mold box includes a top plate, a bottom plate 6, and four side plates 7, which are enclosed by the top plate, bottom plate 6, and side plates 7. The mold box can be the one used in existing flat mold production lines. The side plates 7 include front and rear side plates and left and right side plates that are arranged opposite each other. In this embodiment, positioning support grooves are provided on the left and right side plates as an example.

[0026] Multiple positioning support slots are formed on the same side plate 7. The openings of the positioning support slots connect the top and side of the side plate 7, and the multiple positioning support slots are evenly distributed along the length of the side plate 7. In this embodiment, three positioning support slots are formed on each of the left and right side plates. In use, the positioning connecting bracket 1 is inserted from the top of the side plate 7.

[0027] There are two positioning connecting brackets 1, which are respectively inserted into the positioning support slots on the left and right side plates. Each of the two positioning connecting brackets 1 has a connector 2 on its opposite side. The connector 2 is used to position the reinforcing cage 3 and extends from the side of the side plate 7. Specifically, a positioning connecting bracket 1 is inserted into the positioning support slot on the left side plate, and the connector 2 on the positioning connecting bracket 1 faces the other positioning connecting bracket 1, i.e., towards the right side plate.

[0028] The positioning connecting frame 1 includes multiple support rods 4, each of which is inserted into a positioning support slot and corresponds to one of them. Connectors 2 are mounted on the support rods 4. The positioning support slots and support rods 4 have circular cross-sections. In this embodiment, a positioning connecting frame 1 includes three support rods 4, which are respectively inserted into three positioning support slots on the same side plate 7. The positioning connecting frame 1 also includes a connecting main rod, the ends of which are fixedly connected to the connecting main rod. In this embodiment, the connecting main rod and the support rods 4 are integrally formed.

[0029] The opening width of the positioning support groove is smaller than the width of the positioning connecting frame 1 in the same direction. The positioning support groove is used to prevent the positioning connecting frame 1 from coming out of the opening. Specifically, in cross-section, the size of the opening of the positioning support groove is smaller than the size of the support rod 4, that is, in the cross-sectional direction, the support rod 4 cannot come out of the opening of the positioning support groove.

[0030] There are multiple connectors 2, which are positioned opposite each other to position the same reinforcing cage 3. In this embodiment, each support rod 4 is provided with six connectors 2, which are welded to the support rod 4. The number of connectors 2 on the support rod 4 is the number of reinforcing cages 3 that can be placed in the mold box at the same time, so that six prefabricated wall panels can be produced at one time.

[0031] As attached Figure 2 The reinforcing cage 3 shown has connecting ends 5 on both sides, and the connecting ends 5 are detachably connected to the connector 2. The connecting ends 5 are specially set when cutting reinforcing bars and welding reinforcing cage 3. The connecting ends 5 are located on both sides of reinforcing cage 3. When reinforcing cage 3 is located in the formwork box, the connecting ends 5 are located on the opposite left and right side walls.

[0032] The connector 2 has a hollow hole at the end furthest from the side plate 7, and the connecting end 5 is inserted into the hollow hole. After the reinforcing cage 3 is inserted, the distance between the connectors 2 and the reinforcing cage 3 is fixed. By inserting the connectors 2, the reinforcing cage 3 is clamped and positioned, thus placing the reinforcing cage 3 inside the mold box. At the same time, during the pouring of cement slurry, the reinforcing cage 3 is still restricted by the position of the connectors 2, thereby ensuring that the reinforcing cage 3 remains in an unobstructed position during the pouring process, facilitating subsequent cutting. This enables the mass production of prefabricated wall panels and improves production efficiency.

[0033] In use, the connecting ends 5 on both sides of the reinforcing cage 3 are inserted into the connecting parts 2 on the two positioning connecting frames 1 respectively. The reinforcing cage 3 is clamped by fixing the distance between the two positioning connecting frames 1. Multiple reinforcing cages 3 can be inserted in sequence, and the multiple reinforcing cages 3 are arranged sequentially along the height direction. The positioning connecting frames 1 for inserting the reinforcing cage 3 are inserted into the positioning support grooves on the left and right side plates of the mold box, thereby placing the reinforcing cage 3 inside the mold box, and then directly pouring cement slurry. When opening the mold, since the positioning connecting frames 1 cannot be removed from the positioning support grooves, the positioning connecting frames 1 move with the left and right side plates, thereby separating the positioning connecting frames 1 and the reinforcing cage 3. The positioning connecting frames 1 are removed at the same time as the mold is opened, reducing the operation process and improving production efficiency.

[0034] Example 2

[0035] The difference between this embodiment and Embodiment 1 is that:

[0036] In a rebar cage positioning device for a prefabricated wall panel, the top of the connector 2 has a through hole that connects to the opening of the hollow hole and allows the connecting end 5 to pass through. In use, the positioning connector 1 can be placed in the mold box first, the rebar cage 3 can be placed into the mold box in a staggered manner, and then moved above the through hole and placed into the hollow hole through the through hole, thereby achieving the positioning and clamping of the rebar cage 3.

[0037] The bottom of the positioning support groove is equipped with a guide slope, which slopes from top to bottom along the positioning support groove into the mold box. Before pouring, a release agent needs to be sprayed inside the mold box to facilitate demolding after the cement slurry has formed. The guide slope prevents the release agent from remaining in the positioning support groove, thus improving the efficiency of the release agent.

[0038] Example 3

[0039] The difference between this embodiment and the above embodiments is that:

[0040] In a rebar cage positioning device for a prefabricated wall panel, as shown in the attached... Figure 3 The mold box shown has four side plates 7, which are divided into front and rear side plates and left and right side plates that are arranged opposite each other. When the mold box is closed, the ends of the front and rear side plates abut against the opposite sides of the left and right side plates, respectively. A connecting rod 8 is provided on the side of the front and rear side plates that is furthest from each other. The two ends of the connecting rod 8 are provided with a first thread. Multiple connecting rods 8 are provided on one side plate 7, and these multiple connecting rods 8 are evenly distributed along the height direction. In this embodiment, the connecting rods 8 are welded to the side plate 7, and two connecting rods 8 are provided on one side plate 7.

[0041] Each of the left and right side plates has a connecting sleeve 9 at its end. The number of connecting sleeves 9 at the ends of the left and right side plates is the same as the number of connecting rods 8, and they correspond one-to-one. In this embodiment, the connecting sleeves 9 are welded to the side plates 7. Four connecting sleeves 9 are provided on one side plate 7, and the four connecting sleeves 9 are located at both ends of the side plate 7, that is, they are used in conjunction with the four connecting rods 8 on the front and rear side plates respectively. The setting of multiple connecting rods 8 makes the connection between the side plates 7 more stable.

[0042] Both ends of the connecting rod 8 pass through the connecting sleeves 9 of the two side plates 7. Fasteners are fitted onto the connecting rod 8, and the fasteners have second threads that mate with the first thread. The fasteners are used to prevent the connecting sleeves 9 from coming off the connecting rod 8. In this embodiment, the fasteners are lock nuts, and the number of lock nuts is twice that of the connecting rod 8. The lock nuts are fitted onto both ends of the connecting rod 8 and lock the side plates 7 in place.

[0043] The base plate 6 has protrusions whose cross-section matches the shape of the prefabricated wall panel. The four side plates 7 abut against the four side walls of the protrusions. The top plate abuts against the top of the side plates 7 and is used to close the cavity enclosed by the side plates 7. The top plate has two exposed holes, through which the top of the positioning connecting frame 1 extends. The exposed top of the positioning connecting frame 1 is easy to remove during subsequent disassembly, thus improving production efficiency.

[0044] In this embodiment, the protrusion is integrally formed with the base plate 6, and the cross-sectional dimensions of the protrusion are the dimensions of the assembled wall panel after production. During assembly, the side plates 7 are located around the base plate 6 and abut against the four side walls of the protrusion, so that the base plate 6 and the four side walls form a mold box groove with an open top. After pouring cement grout, the top plate is placed on top of the mold box groove to close the mold box groove and form a complete mold box.

[0045] In use, place the front and rear side plates on the base plate 6, with the front and rear side plates abutting against the opposite side walls of the protrusions. The sides of the front and rear side plates with connecting rods 8 are positioned opposite each other. Then, place the left and right side plates on both sides of the base plate 6. The two ends of the connecting rods 8 pass through the connecting sleeves 9 and move relative to each other along the axial direction of the connecting rods 8 onto the base plate 6. The left and right side plates abut against the other opposite side walls of the protrusions. At this time, the ends of the front and rear side plates abut against the opposite side walls of the left and right side plates, respectively. Then, place the locking nuts at both ends of the connecting rods 8 to fix the relative positions of the connecting rods 8 and the connecting sleeves 9, thereby achieving a tight connection of the four side plates 7. Finally, pour cement grout into the cavity formed by the four side walls and the base plate 6, and seal the cavity through the top plate to allow the cement grout to form and cure.

[0046] In other embodiments, a driving device is also included. This driving device drives the connecting rod 8 to rotate. The first threads at both ends of the connecting rod 8 have opposite directions. Fasteners are located inside the connecting sleeve 9 and are fixedly connected to the connecting sleeve 9. Specifically, the driving device includes a driving gear, which is connected to the two connecting rods 8 on the same side plate 7. The connecting rods 8 are rotatably connected to the side plate 7 via bearings. The driving gear includes a driving gear and two driven gears meshing with the driving gear. The two driven gears are coaxially fixedly connected to the two connecting rods 8 on the same side plate 7, and the driving gear and driven gears have the same axial direction. In this embodiment, the side plate 7 is welded to the outer ring of the bearing, the connecting rod 8 is keyed to the inner ring of the bearing, the driven gear is welded to the connecting rod 8, and the driving gear is mounted on the side plate 7 via an existing gear bracket. Rotation of the driving gear enables the connecting rod 8 to rotate, causing the left and right side plates to move simultaneously relative to each other or in opposite directions, thereby opening and closing the mold box side plate 7. A motor can also be installed to drive the driving gear, thereby achieving automated mold opening and closing and further improving production efficiency.
