Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of precast slab molds, in particular to a casting mold for aerated concrete precast slabs. Background Technique
[0002] Precast slabs, also known as precast concrete slabs, are reinforced concrete slab-shaped components processed in precast factories or construction sites for building assembly. The application of precast concrete slabs in building materials in the modern construction industry has become increasingly widespread. Their advantages compared with traditional on-site cast concrete are mainly manifested in the following aspects: environmental protection and energy conservation: Precast concrete materials can achieve factory production, reducing pollution such as noise, dust, and waste at the construction site, thereby improving environmental protection efficiency. In addition, it has good heat insulation performance and can effectively reduce energy consumption.
[0003] For precast concrete slabs, aerated concrete precast slabs are relatively common. As a new type of energy-saving concrete material, when processed, it generally uses siliceous materials and calcareous materials as the main raw materials, and then needs to add foaming agents and gelling materials and be placed in a concrete mold for processing and forming. During the precast process of aerated concrete precast slabs, steel bars are generally inserted, and then steel bars are inserted into the mold to improve its strength, and then concrete is injected into the mold. After the concrete solidifies, the mold is removed, and a concrete component can be obtained.
[0004] Before pouring concrete into the precast slab, a baffle mechanism is usually used to fully block the steel bar grooves to prevent the concrete from overflowing along the grooves during pouring. However, the currently used baffle mechanism has a relatively simple design, and its function is limited to preventing concrete from overflowing, and it cannot simultaneously perform necessary reinforcement on the precast slab. This limitation may cause the precast slab to deform or displace due to uneven stress during the concrete pouring process, ultimately leading to the failure of the concrete component casting and accompanied by the problem of concrete waste. Summary of the Utility Model
[0005] Aiming at the deficiencies of the existing technology, the utility model provides the following technical solution: A casting mold for aerated concrete precast slabs, including a bottom plate. Short templates are placed on both the left and right sides of the top of the bottom plate, and long templates are placed on both the front and back sides of the top of the bottom plate. The head and tail ends of the short templates and long templates are movably clamped with each other, and steel bar grooves are opened at the tops of the short templates and long templates;
[0006] A baffle mechanism for blocking the steel bar grooves is movably clamped in a cross shape in the steel bar grooves;
[0007] A reinforcement mechanism is fixedly arranged in a two-way support manner on the right side surface of the short template, and the baffle mechanism is movably clamped with the reinforcement mechanism.
[0008] As an improvement of the above technical solution, the baffle mechanism includes a plugging block, which is movably clamped in the steel bar groove. Limiting grooves are opened on the inner walls of the front and rear sides of the steel bar groove, and limiting blocks are movably clamped in the limiting grooves. One end of the limiting block away from the limiting groove is fixedly installed with the plugging block, and a connecting main board is fixedly installed on the right side surface of the plugging block.
[0009] As an improvement of the above technical solution, the reinforcement mechanism includes a positioning hole, which is opened at a position close to the top of the right side surface of the short template. A positioning rod is movably clamped in the positioning hole. The right end of the positioning rod is fixedly installed with a reinforcement main board, and the reinforcement main board is movably clamped with the connecting main board. A first screw rod is movably hinged to the right side surface of the reinforcement main board. The first screw rod is threadedly connected with a bidirectional threaded cylinder. One end of the bidirectional threaded cylinder away from the first screw rod is threadedly connected with a second screw rod. A cubic inclined hole is opened at the top of the bottom plate and on the right side of the short template. A cubic support block is movably clamped in the cubic inclined hole, and the top end of the cubic support block is fixedly installed with the bottom end of the second screw rod.
[0010] As an improvement of the above technical solution, the bottom end of the plugging block is designed with a concave arc.
[0011] As an improvement of the above technical solution, there are multiple baffle mechanisms, and multiple baffles are detachably installed through screw rods.
[0012] As an improvement of the above technical solution, the thread directions of the first screw rod and the second screw rod are opposite.
[0013] The beneficial effects of the present utility model: The head and tail of the short template and the long template are mutually clamped and placed on the bottom plate. The short template is supported and reinforced through the placement of the reinforcement mechanism. After multiple baffle mechanisms are synchronously clamped into the steel bar groove, the reinforcement mechanism is clamped with the baffle mechanism together, strengthening the stability of the connection between the reinforcement mechanism and the short template. This not only prevents the overflow of concrete but also can synchronously perform necessary reinforcement on the precast slab. This comprehensiveness ensures that during the concrete pouring process, the precast slab can be evenly stressed, avoiding the risk of deformation or displacement, thereby greatly improving the success rate of concrete component pouring and effectively reducing the waste problem of concrete.

Specific embodiments
[0019] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0020] Refer to the attached Figure 1 In Figure 1 a points to the front view and b points to the right side view. The above views are only for understanding the solution.
[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: a casting mold for aerated concrete precast slabs, including a bottom plate 1, short formworks 2 are placed on both the left and right sides of the top of the bottom plate 1, long formworks 3 are placed on both the front and back sides of the top of the bottom plate 1, the head and tail ends of the short formworks 2 and the long formworks 3 are movably clamped with each other, and steel bar grooves 21 are opened at the tops of the short formworks 2 and the long formworks 3;
[0022] A baffle mechanism for plugging it is movably clamped in a cross shape in the steel bar groove 21;
[0023] A reinforcing mechanism is fixedly arranged in a bidirectional support manner on the right side surface of the short formwork 2, and the baffle mechanism is movably clamped with the reinforcing mechanism.
[0024] In this implementation scheme, the head and tail of the short formwork 2 and the long formwork 3 are clamped with each other and placed on the bottom plate 1. The short formwork 2 is supported and reinforced by placing the reinforcing mechanism. After synchronously clamping a plurality of baffle mechanisms into the steel bar groove 21, the reinforcing mechanism is then clamped with the baffle mechanism, strengthening the stability of the connection between the reinforcing mechanism and the short formwork 2. This not only prevents the overflow of concrete, but also can synchronously carry out necessary reinforcement on the precast slab. This comprehensiveness ensures that during the concrete pouring process, the precast slab can be uniformly stressed, avoiding the risk of deformation or displacement.
[0025] Specifically, the baffle mechanism includes a plugging block 4, which is movably clamped in the steel bar groove 21. Limiting grooves 41 are provided on the inner walls of the front and rear sides of the steel bar groove 21. A limiting block 42 is movably clamped in the limiting groove 41. One end of the limiting block 42 away from the limiting groove 41 is fixedly installed with the plugging block 4. A connecting main board 43 is fixedly installed on the right side surface of the plugging block 4.
[0026] In this embodiment, the steel bar groove 21 is blocked through the cooperation of the internal structures of the baffle mechanism, thereby preventing the overflow of concrete.
[0027] Specifically, the reinforcement mechanism includes a positioning hole 5, which is provided at a position close to the top of the right side surface of the short formwork 2. A positioning rod 51 is movably clamped in the positioning hole 5. The right end of the positioning rod 51 is fixedly installed with a reinforcement main board 52. The reinforcement main board 52 is movably clamped with the connecting main board 43. A first screw rod 53 is movably hinged on the right side surface of the reinforcement main board 52. The first screw rod 53 is threadedly connected with a bidirectional threaded cylinder 54. One end of the bidirectional threaded cylinder 54 away from the first screw rod 53 is threadedly connected with a second screw rod 55. A cubic inclined hole 56 is provided at the top of the bottom plate 1 and on the right side of the short formwork 2. A cubic support block 57 is movably clamped in the cubic inclined hole 56. The top end of the cubic support block 57 is fixedly installed with the bottom end of the second screw rod 55.
[0028] In this embodiment, the precast slab is supported and reinforced through the cooperation of the internal structures of the reinforcement mechanism, thereby preventing the precast slab from deforming or displacing due to uneven force.
[0029] Specifically, the bottom end of the plugging block 4 is designed with a concave arc.
[0030] In this embodiment, the bottom of the plugging block 4 is closely attached to the outside of the steel bar.
[0031] Specifically, there are multiple baffle mechanisms, and multiple baffles are detachably installed through screw rods.
[0032] In this embodiment, according to the lengths of the short formwork 2 and the long formwork 3, the number of baffle mechanisms to be detachably installed together through screw rods is selected, thereby improving the applicability of the baffle mechanism to short formworks 2 and long formworks 3 with different lengths.
[0033] Specifically, the thread directions of the first screw rod 53 and the second screw rod 55 are opposite.
[0034] In this embodiment, when the bidirectional threaded cylinder 54 is rotated, the first screw rod 53 and the second screw rod 55 can move in opposite directions.
[0035] In use, the head and tail of the short template 2 and the long template 3 are clamped with each other and placed on the bottom plate 1. According to the lengths of the short template 2 and the long template 3, the number of baffle mechanisms to be detachably installed together by screws is selected, thereby improving the applicability of the baffle mechanism to short templates 2 and long templates 3 of different lengths. Then, the steel bars are placed one by one in the steel bar grooves 21, and the positioning rods 51 are inserted into the positioning holes 5. At this time, the bidirectional threaded cylinder 54 is rotated. Under the cooperation of the first screw 53, the bidirectional threaded cylinder 54 and the second screw 55 move relatively downward, so that the cubic support block 57 is clamped into the cubic inclined hole 56. The short template 2 is supported and reinforced through the cooperation of structures such as the cubic support block 57 and the reinforcement main board 52. Multiple blocking blocks 4 are simultaneously clamped in the corresponding steel bar grooves 21, so that the limiting blocks 42 are clamped in the limiting grooves 41. Then, the connecting main board 43 is clamped with the reinforcement main board 52. Through the cooperation of structures such as the limiting blocks 42 and the connecting main board 43, the stability of the connection between the reinforcement mechanism and the short template 2 is strengthened. This not only prevents the overflow of concrete, but also can synchronously carry out necessary reinforcement on the precast slab. This comprehensiveness ensures that during the aerated concrete pouring process, the precast slab can be evenly stressed, avoiding the risks of deformation or displacement, thereby greatly improving the success rate of concrete component pouring and effectively reducing the waste problem of concrete.
[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
