Description

Technical Field

[0001] The present application relates to the technical field of prefabricated component moulds, and in particular to a combined prefabricated beam mould. Background Art

[0002] Precast beams are prefabricated in factories and then transported to the construction site for installation and fixation according to the design requirements. In the process of producing precast beams, molds are needed. Concrete is poured into the cavity in the mold. After the concrete solidifies, the formed precast beam can be taken out of the mold.

[0003] The existing precast beam mold includes a mold base, side molds fixed on the two lengthwise side walls of the mold base by bolts, and two end molds fixed on the widthwise side walls of the mold base by bolts. The side molds and the end molds are fixed by bolts. The staff pours concrete into the cavity formed by the side molds and the end molds, and waits for the concrete to solidify, thereby realizing the production of the precast beam. After the production of the precast beam is completed, the bolts between the base and the side molds, the base and the end molds, and the side molds and the end molds are loosened, and the side molds and the end molds are lifted away, thereby realizing the production of the precast beam.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the production molds of the above-mentioned precast beams require the side molds and end molds to be dismantled and moved away for each component production before the component can be demoulded and lifted. When the next component is produced, the mold must be reinstalled and repositioned before pouring. There is a problem of frequent disassembly and assembly of the mold, which leads to low production efficiency, and there is room for improvement. Summary of the invention

[0005] In order to reduce the frequency of disassembly and assembly of molds during the production of precast beams and improve production efficiency, the present application provides a combined precast beam mold.

[0006] The present application provides a combined prefabricated beam mold, which adopts the following technical solution:

[0007] A combined prefabricated beam mold comprises a base, a side mold rotatably arranged in the length direction of the base and an end mold fixed in the width direction of the base, a plurality of support rods are fixed on the base, inner mold plates are fixed on both side walls of the support rods, an inclined surface is provided on the side of the side mold facing the base, a receiving rod is fixed on the base, a traction rod is rotatably connected to the receiving rod, the traction rod is threadedly connected to the side mold, and a limiter for limiting the rotation of the side mold is provided on the support rod.

[0008] By adopting the above technical solution, the side mold, the end mold and the inner mold form two chambers. The staff pours concrete into the chambers and can produce two precast beams at one time. After the precast beam to be produced is formed, the traction rod is rotated. Under the traction of the traction rod and the guidance of the inclined surface, the side plate is rotated in the direction away from the inner membrane plate. At this time, it is convenient to lift the precast beam out of the mold. After the precast beam is taken out of the mold, the traction rod is rotated. Under the drive of the traction rod, the side plate is rotated toward the direction of the inner membrane plate. The limiter limits the rotation of the side plate, so that the deformation of the mold is reduced during the precast beam forming process, thereby producing qualified precast beams. The staff does not need to remove the side mold and the end mold during the production of the precast beam, thereby improving the production efficiency of the precast beam.

[0009] Optionally, the limiting member includes a connecting rod fixed on the support rod and a limiting rod fixed on the outer wall of the side mold, one end of the connecting rod is fixed on the support rod, and the other end is slidably connected to the limiting rod, a fixing block is threadedly connected to the outer wall of the connecting rod, and the fixing block abuts against the side wall of the limiting rod.

[0010] By adopting the above technical solution, the staff adjusts the opening angle of the mold according to the shape and size of the precast beam to be produced, and then rotates the fixed block.

[0014] By adopting the above technical solution, when it is necessary to reduce the depth of the mold, the staff lays the first height mold on the base to facilitate the production of prefabricated beams whose height is less than the depth of the mold; when it is necessary to increase the depth of the mold, the second height mold is installed on the side of the side mold away from the base, thereby increasing the depth of the mold, thereby facilitating the production of prefabricated beams whose height is greater than the height of the side mold.

[0015] Optionally, a storage cavity is fixed on the outer wall of the side mold, a conveying path is fixed on the outer wall of the storage cavity, a plurality of first height molds are installed on the inner wall of the storage cavity, a first driving member for driving the first height molds to slide is arranged on the outer wall of the storage cavity, and a second driving member for driving the first height molds to slide in the conveying path is arranged on the outer wall of the conveying path.

[0016] By adopting the above technical solution, multiple first height molds are pre-loaded into the storage cavity. When the first height mold needs to be laid on the base, the staff loosens the bolts on the end mold and moves the end mold away from the base. The first driving member drives the first height mold to slide into the conveying path, and the second driving member drives the first height mold to between the side mold and the inner mold plate. Under the mutual urging of the first height molds, the first height molds are arranged in sequence on the base. The staff only needs to load the first height mold into the storage cavity near the storage cavity.

[0017] Optionally, the first driving member includes a driving frame slidably connected to the storage cavity and a driving spring fixed to the driving frame, one end of the driving spring is fixed to the outer wall of the driving frame, and the other end is fixed to the outer wall of the storage cavity.

[0018] By adopting the above technical solution, the driving frame abuts against the side wall of the first height mold, and under the support of the first height mold, the driving spring is stretched, and under the action of the driving spring's own rebound force, the driving frame slides toward the inner cavity of the storage chamber, thereby driving the first height mold to slide into the inner cavity of the conveying channel.

The rotation of the loading shell facilitates the arrangement of the first height mold in the storage cavity. After the first height mold is laid, the paddle is tightly attached to the outer wall of the loading shell under the action of the self-rebound force of the traction spring, thereby reducing interference with the transportation of the first height mold; under the action of the self-rebound force of the driving spring, the driving frame abuts against the side wall of the first height mold close to the driving frame, and applies a force toward the conveying path to the first height mold.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The base, side molds and end molds form a cavity for pouring precast beams. The limiter restricts the rotation of the side molds, so that the molds have good stability during the pouring process; after the concrete poured into the mold solidifies, the worker turns the traction rod, which pulls the side molds, and under the guidance of the inclined surface, the side molds rotate toward the receiving rod, making it easier for the worker to lift the formed precast beams. The entire process of producing precast beams does not require the removal of parts on the mold, thereby improving production efficiency.

[0025] 2. The staff fixes the end mold at different positions on the base through the fixing holes, so as to facilitate the production of precast beams of different lengths; moves the side mold and fixes the side mold through the locking holes, so as to facilitate the production of precast beams of different widths; by laying the first height mold on the base and adding the second height mold on the side mold, it is convenient to produce precast beams of different heights, thereby improving the practicality of the mold.

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses a combined prefabricated beam mold.

[0035] Embodiment 1:

[0036] Reference Figure 1 A combined prefabricated beam mold includes a base 1, which is a rectangular structure. A plurality of support rods 4 are welded and fixed on the base 1. The support rods 4 are located in the middle of the base 1 and are evenly spaced along the length direction of the base 1. Inner molds 5 are welded and fixed on both sides of the support rods 4. Four end molds 3 are fixed by bolts in the width direction of the base 1. Two end molds 3 are fixed at one end of the base 1. Side molds 2 are fixed by bolts in the length direction of both sides of the base 1. The base 1, the end molds 3, the side molds 2 and the inner molds 5 form two cavities. Workers can pour concrete into the two cavities to produce two prefabricated beams at a time.

[0037] Reference Figure 1The side mold 2 is provided with an inclined surface 6 on the side facing the base 1. The opening of the inclined surface 6 and the base 1 forms an angle away from the direction of the support rod 4. The upper surface of the base 1 is fixed with abutment bars 32 by bolts. The abutment bars 32 abut against the side wall of the side mold 2 to limit the position of the side mold 2. Under the guidance of the inclined surface 6, the rotation of the side mold 2 can be realized; a receiving rod 7 is welded and fixed on the base 1. The end of the receiving rod 7 away from the base 1 is rotatably connected with a traction rod 8. The traction rod 8 is threadedly connected to the side mold 2. The staff rotates the traction rod 8. Under the traction of the traction rod 8, the rotation of the side mold 2 can be realized, which is convenient for taking the precast beam that has been produced out of the mold.

[0038] Reference Figure 1 A limit piece 9 for limiting the rotation of the side mold 2 is provided on the support rod 4. The limit piece 9 limits the rotation of the side mold 2, making the production process of the precast beam more stable; the limit piece 9 includes a limit rod 11 fixed to the outer wall of the side mold 2 by welding and a connecting rod 10 fixed to the receiving rod 7 by a nut. A fixing block 12 is threadedly fixed on the outer wall of the connecting rod 10. In this application, the fixing block 12 adopts a nut. The staff rotates the fixing block 12 so that the fixing block 12 abuts against the side wall of the limit rod 11, and under the traction of the limit rod 11 and the connecting rod 10, it plays a role in limiting the rotation of the side mold 2.

[0039] Reference Figure 2 The base 1 is provided with a plurality of fixing holes 13 along its own width direction. The staff inserts bolts into the fixing holes 13 and fixes the end mold 3 at different positions of the base 1 by means of the bolts, thereby facilitating the production of precast beams of different lengths; the base 1 is provided with a plurality of locking holes 14 along its own length direction. The staff moves the side mold 2, inserts bolts into the locking holes 14, and fixes the side mold 2 at different positions of the base 1 by means of the bolts, thereby changing the distance between the side mold 2 and the inner mold 5, thereby facilitating the production of precast beams of different widths.

[0040] Reference Figure 2 , a first height mold 15 is laid on the base 1, and the first height mold 15 is located between the inner mold 5 and the side mold 2; the side of the side mold 2 facing away from the base 1 is detachably connected with a second height mold 16. When it is necessary to produce a precast beam whose height is less than the depth of the mold cavity, according to the height requirement of the precast beam, the staff lays the first height mold 15 of the corresponding height on the base 1, and reduces the depth of the mold to facilitate the production of precast beams less than the height of the mold cavity; when it is necessary to produce a precast beam whose height is greater than the depth of the mold cavity, the second height mold 16 is fixed on the side mold 2 and the inner mold 5, so that the depth of the mold is increased, thereby facilitating the production of precast beams whose height is greater than the depth of the mold cavity.

[0041] In the first embodiment of the present application, the implementation principle of a combined prefabricated beam mold is as follows: before producing the prefabricated beam, according to the specifications of the prefabricated beam to be produced, the position of the side mold 2 is adjusted to change the width of the mold cavity, and the position of the end mold 3 is adjusted to change the length of the mold cavity. By laying the first height mold 15 on the base 1 or fixing the second height mold 16 on the side wall of the side mold 2, the depth of the mold cavity is changed, so as to facilitate the production of prefabricated beams of different specifications. After the adjustment of the mold is completed, concrete is poured into the mold cavity, and the production of the prefabricated beam is realized after the concrete solidifies. After the production of the prefabricated beam is completed, the fixing block 12 is loosened, the traction rod 8 is rotated, and the side mold 2 is rotated toward the receiving rod 7 under the traction of the traction rod 8, so as to facilitate the lifting of the prefabricated beam from the mold; after taking out the prefabricated beam, the traction rod 8 is rotated, and the side plate is rotated to the initial position under the contact of the traction rod 8, so as to facilitate the subsequent production of prefabricated beams.

[0042] Embodiment 2:

[0043] The difference between the second embodiment and the first embodiment is that: Figure 3 A storage cavity 17 is fixed on the outer wall of the side mold 2 by bolts. The storage cavity 17 is used to install the first height mold 15. A conveying path 18 is welded and fixed on the side wall of the storage cavity 17, and is conveyed to the storage cavity 17. A first driving member 20 for driving the first height mold 15 to slide is arranged on the side wall of the storage cavity 17. Under the drive of the first driving member 20, the first height mold 15 can be transported to the conveying path 18.

[0044] Reference Figure 3 The discharge port of the conveying path 18 is located at the position of the end mold 3. A second driving member 21 is provided on the outer wall of the conveying path 18 for driving the first height mold 15 entering the conveying path to slide. After the first height mold 15 enters the conveying path 18, the second driving member 21 drives the first height mold 15 to slide and transports the first height mold 15 to a position close to the end mold 3.

[0045] Reference Figure 3 and Figure 4 The first driving member 20 includes a driving frame 22 slidably connected to the storage chamber 17 and a driving spring 23 welded and fixed to the driving frame 22. One end of the driving spring 23 is welded and fixed to the outer wall of the driving frame 22, and the other end is welded and fixed to the outer wall of the storage chamber 17. The driving frame 22 abuts against the outer wall of the first height mold 15, so that the driving spring 23 is stretched. Under the action of the self-rebound force of the driving spring 23, the driving frame 22 drives the first height mold 15 to slide into the inner cavity of the conveying path 18.

[0046] Reference Figure 4The second driving member 21 includes a sliding frame 24 slidingly connected to the conveying path 18 and a rotating handle 25 rotatably connected to the conveying path 18. In the present application, the rotating handle 25 is arranged in an L-shape. The rotating handle 25 is rotatably connected to the conveying path 18. A sliding groove 26 is penetrated through the side wall of the sliding frame 24. One end of the rotating handle 25 away from the conveying path 18 is rotatably connected in the sliding groove 26. During the rotation of the rotating handle 25, the rotating handle 25 slides in the sliding groove 26, thereby realizing the sliding of the sliding frame 24.

[0047] Reference Figure 4 A driving motor 27 is fixed to the outer wall of the conveying path 18 by bolts, and the rotating shaft of the driving motor 27 is welded and fixed to the rotating handle 25. The driving motor 27 is electrically connected to an external power supply, and the driving motor 27 is started, and the rotating shaft of the driving motor 27 rotates, thereby driving the rotating handle 25 to rotate. When the first height mold 15 needs to be laid on the base 1, the bolts on the side mold 2 are loosened, and the side mold 2 is moved away from the base 1, and the first height mold 15 is transported into the mold by sliding the sliding frame 24 and the driving frame 22.

[0048] Reference Figure 4 and Figure 5 A loading shell 28 is rotatably connected to the inner wall of the storage chamber 17, and a paddle 29 is rotatably connected to the outer wall of the loading shell 28. A pressing rod 31 is welded and fixed to the side wall of the paddle 29. When all the first height molds 15 in the storage chamber 17 are transported to the base 1, the staff pulls the pressing rod 31 to make the paddle 29 abut against the driving frame 22, so that the driving frame 22 slides out of the storage chamber 17. At this time, it is convenient to load the first height mold 15 into the storage chamber 17. The rotating setting of the loading shell 28 makes it convenient for the staff to arrange the first height mold 15 in the storage chamber 17.

[0049] Reference Figure 4 and Figure 5 A traction spring 30 is installed between the paddle 29 and the outer wall of the loading shell 28. One end of the traction spring 30 is welded and fixed to the outer wall of the paddle 29, and the other end is welded and fixed to the outer wall of the loading shell 28. When the staff pulls the paddle 29 to drive the driving frame 22 to slide, the traction spring 30 is stretched. After completing the installation of the first height mold 15, the pressing rod 31 is released. Under the action of the self-rebound force of the traction spring 30, the paddle 29 is attached to the outer wall of the loading shell 28, thereby reducing the possibility of interference with the driving frame 22 driving the first height mold 15.

[0050] The implementation principle of a combined prefabricated beam mold in the embodiment of the present application is as follows: when it is necessary to reduce the depth of the mold cavity, the staff pulls the pressing rod 31, the paddle 29 swings the driving frame 22 to slide out of the storage cavity 17, and the first height mold 15 is loaded into the storage cavity 17 through the loading shell 28. During the installation of the first height mold 15, the pressing rod 31 is pulled to make the driving frame 22 slide out of the storage cavity 17, and the first height mold 15 is loaded into the storage cavity 17 through the inner cavity of the loading shell 28. The driving spring 23 is stretched. Under the action of the self-rebound force of the spring 23, the driving frame 22 has a tendency to slide into the storage cavity 17, and the first height mold 15 close to the conveying path 18 slides into the conveying path 18, and the driving motor 27 is started. The rotating shaft of the driving motor 27 rotates, driving the rotating handle 25 to rotate, and the rotating handle 25 drives the sliding frame 24 to slide, thereby driving the first height mold 15 in the conveying path 18 to slide into the mold. The staff only needs to install the first height mold 15 in the storage cavity 17, thereby saving a lot of time for the staff.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
