Technical Field

[0001] The utility model relates to the technical field of precast concrete processing devices, in particular to a side form device for manufacturing precast concrete floor slabs. Background Art

[0002] Precast concrete components refer to building components produced by using concrete as raw materials in a factory through molds, and then transported to a construction site for installation. For example, common precast concrete floor slabs, precast concrete beams, and precast concrete columns are all precast concrete components.

[0003] When producing precast concrete floor slabs, the precast concrete floor slabs need to be precast through the cooperation of a bottom form, side forms, and a top form. The side forms are usually welded by angle irons and rib plates, and then multiple angle irons are welded together to form the side forms. The side forms are molds for molding the four sides of the precast concrete floor slabs.

[0004] The existing side forms for precast concrete floor slabs are usually integrally welded by welding. Each integrally welded side form device can only manufacture precast concrete floor slabs of one size. Therefore, each time precast concrete floor slabs of different lengths are processed, new side forms need to be customized again, which is not convenient for processing precast concrete floor slabs of different lengths, inconvenient to use, and has poor applicability.

[0034] Embodiment

[0035] Refer to Figures 1-4As shown in the figure, the utility model provides a side formwork device for manufacturing precast concrete floor slabs, which includes a first vertical side formwork 1, a second vertical side formwork 2, a first horizontal side formwork 3, a second horizontal side formwork 4 and a fixing member 5. Among them, the first vertical side formwork 1, the second vertical side formwork 2, the first horizontal side formwork 3 and the second horizontal side formwork 4 are all horizontally arranged. The first vertical side formwork 1 and the second vertical side formwork 2 are arranged in parallel, the first horizontal side formwork 3 and the second horizontal side formwork 4 are arranged in parallel. The two ends of the first horizontal side formwork 3 are respectively detachably connected to the ends of the facing sides of the first vertical side formwork 1 and the second vertical side formwork 2. The second horizontal side formwork 4 is arranged between the first vertical side formwork 1 and the second vertical side formwork 2 and slides along the length direction of the first vertical side formwork 1 and the second vertical side formwork 2 to adjust the distance between the first horizontal side formwork 3 and the second horizontal side formwork 4, so as to adjust the size of the space enclosed by the first vertical side formwork 1, the second vertical side formwork 2, the first horizontal side formwork 3 and the second horizontal side formwork 4 to adapt to precast concrete floor slabs of different lengths. At the same time, the fixing member 5 is arranged on one end of the second horizontal side formwork 4 facing the first vertical side formwork 1 and / or on one end of the second horizontal side formwork 4 facing the second vertical side formwork 2. When the second horizontal side formwork 4 moves to a preset position so that the enclosed space meets the size of the precast concrete floor slab, the fixing member 5 fixes the second horizontal side formwork 4, making the second horizontal side formwork 4 unable to slide along the length direction of the first vertical side formwork 1 and restricting the movement of the second horizontal side formwork 4.

[0036] The second horizontal side formwork 4 can slide along the length direction of the first vertical side formwork 1 between the first vertical side formwork 1 and the second vertical side formwork 2, so as to adjust the size of the space enclosed by the first vertical side formwork 1, the second vertical side formwork 2, the first horizontal side formwork 3 and the second horizontal side formwork 4, and process precast concrete floor slabs of different lengths. When the second horizontal side formwork 4 moves to a position with a preset size, at this time, the second horizontal side formwork 4 is directly fixed by the fixing member 5, making the second horizontal side formwork 4 unable to move along the length direction of the first vertical side formwork 1, so that precast concrete floor slabs can be processed between the first vertical side formwork 1, the second vertical side formwork 2, the first horizontal side formwork 3 and the second horizontal side formwork 4. It is convenient to use and has strong applicability. By adjusting the position of the second horizontal side formwork 4, precast concrete floor slabs of different lengths can be processed without replacing the side formwork device.

[0037] Specifically, for the fixing member 5, one or two fixing members 5 can be provided. When one fixing member 5 is provided, it can be arranged between the second transverse side mold 4 and the first vertical side mold 1, or between the second transverse side mold 4 and the second vertical side mold 2. The second transverse side mold 4 can be fixed to the first vertical side mold 1 or the second vertical side mold 2 through the fixing member 5, so that the second transverse side mold 4 can no longer slide along the length direction of the first vertical side mold 1, restricting the movement of the second transverse side mold 4. When two fixing members 5 are provided, one fixing member 5 can be arranged between the second transverse side mold 4 and the first vertical side mold 1, and another fixing member 5 can be arranged between the second transverse side mold 4 and the second vertical side mold 2. Through the fixing member 5, both ends of the second transverse side mold 4 are respectively fixed to the first vertical side mold 1 and the second vertical side mold 2, making the effect of fixing the second transverse side mold 4 better and the fixing more firm.

[0038] As a specific implementation manner, a fixing plate 6 is provided at the top of the first vertical side mold 1 and / or the second vertical side mold 2 along its length direction. In this embodiment, when one fixing member 5 is provided, only one fixing plate 6 is provided, and it is arranged at the top of the first vertical side mold 1 and extends along the length direction of the first vertical side mold 1. The length of the fixing plate 6 is the same as the length of the first vertical side mold 1. When two fixing members 5 are provided, two fixing plates 6 are provided, and they are respectively arranged at the tops of the first vertical side mold 1 and the second vertical side mold 2. A plurality of first positioning holes 7 are formed in the fixing plate 6. The plurality of first positioning holes 7 are uniformly arranged along the length direction of the fixing plate 6, and the plurality of first positioning holes 7 are on the same straight line.

[0039] The fixing member 5 includes a fixing block 51 arranged on the top of the second transverse side form 4. A second positioning hole 52 is formed in the fixing block 51. There is one second positioning hole 52, and the axis of the first positioning hole 7 is parallel to the axis of the second positioning hole 52. A positioning bolt 53 is arranged at the second positioning hole 52. When the second transverse side form 4 is moved to a preset position so that the second positioning hole 52 is coaxial with one of the first positioning holes 7, it is necessary to fix the second transverse side form 4. At this time, the positioning bolt 53 sequentially penetrates into the second positioning hole 52 and the first positioning hole 7, and the side wall of the positioning bolt 53 abuts against the inner walls of the second positioning hole 52 and the first positioning hole 7, fixing the second transverse side form 4 on the first vertical side form 1, restricting the movement of the second transverse side form 4, and enabling the first vertical side form 1, the second vertical side form 2, the first transverse side form 3, and the second transverse side form 4 to enclose a fixed space for manufacturing a precast concrete floor slab; when it is necessary to manufacture precast concrete floor slabs of different lengths, at this time, directly take out the positioning bolt 53 from the first positioning hole 7 and the second positioning hole 52, so that the fixing block 51 is not limited on the fixing plate 6, thereby enabling the second transverse side form 4 to move along the length direction of the first vertical side form 1 until the second transverse side form 4 moves to a position where the space enclosed by the first vertical side form 1, the second vertical side form 2, the first transverse side form 3, and the second transverse side form 4 matches the new size of the precast concrete floor slab. At this time, take out the positioning bolt 53 again, and penetrate the positioning bolt 53 into the first positioning hole 7 coaxial with this position and the second positioning hole 52 again to restrict the movement of the second transverse side form 4 and manufacture the precast concrete floor slab.

[0040] As an alternative embodiment, a waist-shaped hole 8 is formed in the fixing plate 6 along its length direction. A connecting rod 9 is arranged on the top of the second transverse side form 4. The connecting rod 9 penetrates into the waist-shaped hole 8 and can slide along the length direction of the waist-shaped hole 8. One end of the connecting rod 9 is fixed to the top of the second transverse side form 4. The fixing block 51 is connected to the end of the connecting rod 9 facing away from the second transverse side form 4, and the fixing block 51 is located on the side of the fixing plate 6 facing away from the second transverse side form 4. When fixing the second transverse side form 4, the first positioning hole 7 and the second positioning hole 52 are coaxial, and the positioning bolt 53 penetrates into the first positioning hole 7 and the second positioning hole 52. At this time, through the waist-shaped hole 8 and the connecting rod 9, the fixing block 51 is transferred outside the space enclosed by the first vertical side form 1, the second vertical side form 2, the first transverse side form 3, and the second transverse side form 4, so that the fixing block 51 does not affect the placement of structures such as the top form. In addition, the connecting rod 9 is detachably connected to both the second transverse side form 4 and the fixing block 51. When installing, first penetrate the connecting rod 9 into the waist-shaped hole 8 at this time, and then detachably connect the connecting rod 9 to the fixing block 51 and the second transverse side form 4, making the installation more convenient.

[0041] A placement groove 10 is provided on the side of the fixing plate 6 facing the second horizontal side mold 4, and the placement groove 10 is arranged along the length direction of the fixing plate 6. The waist-shaped hole 8 and the first positioning hole 7 are both provided in the placement groove 10. When the positioning bolt 53 extends into the first positioning hole 7, one end of the positioning bolt 53 passes through the first positioning hole 7 and is located in the placement groove 10, so that the positioning bolt 53 will not protrude from the placement groove 10, thereby preventing the positioning bolt 53 from extending out of the placement groove 10 and affecting the placement of the top mold.

[0042] The fixing block 51 is fixedly connected to the mounting bracket 11 on the side facing away from the second transverse side mold 4, and the positioning bolt 53 is threadedly connected to the mounting bracket 11. When the positioning bolt 53 is rotated, the positioning bolt 53 can move away from or close to the first positioning hole 7. When the second transverse side mold 4 needs to be fixed, the positioning bolt 53 is rotated at this time to move the positioning bolt 53 toward the first positioning hole 7 and the second positioning hole 52 until the positioning bolt 53 extends into the first positioning hole 7 and the second positioning hole 52, and the first positioning hole 7 and the second positioning hole 5 2, thereby restricting the fixing block 51, and further restricting and fixing the second transverse side mold 4, so that the second transverse side mold 4 cannot move. When it is necessary to make precast concrete slabs of different lengths, the positioning bolt 53 is rotated in the opposite direction again to remove the positioning bolt 53 from the first positioning hole 7 and the second positioning hole 52. The setting of the mounting bracket 11 can place the positioning bolt 53, and avoid the positioning bolt 53 being lost when it is taken out of the first positioning hole 7 and the second positioning hole 52.

[0043] Both ends of the second horizontal side mold 4 are connected with sealing plates 12, which are in contact and sealed with the second vertical side mold 2 and the side walls of the first vertical side mold 1. The sealing plates 12 are made of oil-resistant vulcanized foam rubber material. The sealing plates 12 are used to reduce the gap between the second horizontal side mold 4 and the first vertical side mold 1 and the gap between the second horizontal side mold 4 and the second vertical side mold 2 to avoid leakage.

[0044] At the same time, the first transverse side mold 3 and the second transverse side mold 4 are each provided with multiple sections, the multiple sections of the first transverse side mold 3 are in the same straight line, and the two adjacent sections of the first transverse side mold 3 are detachably connected, and the multiple sections of the second transverse side mold 4 are in the same straight line, and the two adjacent sections of the second transverse side mold 4 are detachably connected. The setting of the multiple sections of the first transverse side mold 3 and the second transverse side mold 4 can adjust the length of the first transverse side mold 3 and the second transverse side mold 4 according to the precast concrete floor slabs of different widths to adapt to the precast concrete floor slabs of different widths.

[0045] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model.
