Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated templates, in particular to a concrete mold for prefabricating beams and slabs. Background Art

[0002] In the production of prefabricated bridge beams and slabs, steel molds are generally used as vertical molds, which usually need to be assembled and adjusted manually by a lifting crane, which is inefficient and slow. Each time, manual measurement, angle adjustment, and leveling are required. Therefore, it is impossible to ensure that the assembled templates are exactly the same each time, and the quality of the products produced is also uneven. In the prior art, a Chinese patent application with publication number CN110480803B discloses a special forming mold for prefabricated beams and slabs. The opening and closing of the side molds on both sides are realized by setting a bottom mold and a side mold hinged on both sides in conjunction with an oil cylinder installed on the outside of each side mold. Although the efficiency is improved, the multiple oil cylinders on both sides increase the equipment cost and maintenance cost. Since the hinge is set on one side of the bottom mold, the hinge is easily buried and corroded by the mud and water of the bottom mold, resulting in a reduced mold life and an increased failure rate. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a concrete mold for prefabrication of beams and slabs in response to the above-mentioned technical deficiencies. The hinge seats are arranged on both sides of the bottom of the bottom mold, and the side molds are hinged to the bottom mold by arranging cantilevers, thereby solving the problem that the hinges of the existing mold are easily buried and corroded by the mud and water of the bottom mold.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a concrete mold for prefabrication of beams and slabs, including a bottom mold, the two sides of the bottom mold are hinged to the side molds through hinge seats, the hinge seats are arranged on both sides of the bottom of the bottom mold, a cantilever is provided on one side of the bottom of the side mold, the cantilever is hinged in the hinge seat, and the bottom side of the side mold is hinged with a driving mechanism.

[0005] To further optimize the technical solution, a fixed base is provided at the bottom of the bottom mold, a boss portion is provided in the middle of the base, the top surface of the boss portion is fixedly connected to the bottom surface of the bottom mold, grooves open on the outside are provided on both sides of the boss portion, and a hinge seat is arranged in the groove.

[0006] To further optimize the technical solution, the driving mechanism includes a vertically arranged oil cylinder fixed at the bottom of the bottom mold, and articulated arms are respectively provided on the outer sides of the bottoms of the two symmetrical side molds, and a connecting rod is respectively hinged between the end of each articulated arm away from the side mold and the end of the telescopic rod of the oil cylinder.

[0007] To further optimize the technical solution, a plurality of notches are provided on both sides of the bottom mold, and the plurality of notches are arranged between the connecting surfaces of the bottom mold and the side molds.

[0008] Compared with the prior art, the utility model has the following advantages: 1. The articulated seats are arranged on both sides of the bottom of the bottom mold, and the side molds are hinged to the bottom mold by arranging cantilevers. The articulated seats are suspended on the bottom surface of the bottom mold, so that mud and water are not easy to penetrate into the articulated seats, thereby improving the service life of the mold and reducing maintenance costs; 2. The bottom mold is lifted upward by arranging the base and the boss part, thereby further improving the vertical height of the junction seat; 3. By arranging the cylinder at the bottom of the bottom mold, a cylinder is provided to respectively articulate two connecting rods, and the two connecting rods on both sides respectively drive the articulated arms to realize the synchronous opening and closing of the side molds, thereby reducing equipment costs and improving the efficiency of mold opening and closing.

[0013] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in conjunction with the reference drawings of specific embodiments. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0014] It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. used in this application document to indicate positions or positional relationships are based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present disclosure and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present disclosure. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0015] Combination Figures 1 to 3As shown, a concrete mold for beam and slab prefabrication comprises a bottom mold 1 and side molds 2 connected to the bottom mold 1 on both sides. The bottom of the bottom mold 1 is provided with hinge seats 11 on both sides, and a cantilever 21 is provided on one side of the bottom of the side mold 2. The cantilever 21 is hinged in the hinge seat 11. The side mold 2 is hinged to the side mold 2 through the hinge seat 11. The bottom of the bottom mold 1 is provided with a fixed base 3. The middle of the base 3 is provided with a boss portion 31. The top surface of the boss portion 31 is fixedly connected to the bottom surface of the bottom mold 1. The boss portion 31 is provided with grooves 32 with open outer sides on both sides. The hinge seat 11 is arranged in the grooves 32. A plurality of notches 10 are provided on both sides of the bottom mold 1. The plurality of notches 10 are arranged between the connecting surfaces of the bottom mold 1 and the side mold 2. The bottom side of the side mold 2 is hinged with a driving mechanism.

[0016] The driving mechanism includes a vertically arranged cylinder 4, which is fixed to the bottom of the bottom mold 1. The bottom outer sides of the two symmetrical side molds 2 are respectively provided with articulated arms 22, and a connecting rod 5 is respectively hinged between the end of each articulated arm 22 away from the side mold 2 and the end of the telescopic rod of the cylinder 4.
