Description

Technical Field

[0001] The utility model relates to the field of concrete precast blocks, and particularly relates to a concrete precast block molding machine. Background Art

[0002] As a building material, concrete can be traced back to the ancient Roman period. With the development of material science and engineering technology, the performance of concrete has been significantly improved. Modern concrete is usually composed of cement, aggregates, water and admixtures, and its strength and durability can meet various construction requirements. In the early 20th century, with the acceleration of the industrialization process, the construction industry began to explore more efficient construction methods. Concrete precast blocks are widely used in various construction projects, including residential buildings, commercial buildings, public facilities and infrastructure construction, etc. Many high-rise buildings and large-scale infrastructure projects in modern cities have adopted precast technology.

[0003] Concrete precast blocks can be classified according to their functions and shapes, mainly including:

[0004] Wall precast blocks: such as concrete wall panels, used for exterior and interior walls of buildings;

[0005] Floor precast blocks: such as prestressed concrete slabs, used for load-bearing structures between floors;

[0006] Beams and columns: main components used for supporting structures;

[0007] Special components: such as precast beams for bridges, tunnel lining blocks, etc.

[0008] Precast concrete technology uses factory prefabrication and then on-site assembly; therefore, the precast concrete blocks for construction are all prefabricated in the factory. The existing templates used for precast concrete blocks are all customized or wooden templates. Among them, the use of steel templates is only applicable to specially customized concrete blocks, with poor applicability; while the use of wooden templates results in large material consumption, high cost and low reuse rate.

[0009] In view of this, in order to solve the above problems, a new molding machine for concrete precast blocks has been designed and improved. Content of the Utility Model

[0023] 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 with reference to the accompanying drawings and embodiments.

[0024] As Figures 1 to 2 shown, a concrete precast block mold - making machine is used to replace the original customized steel mold or wooden mold to support the concrete raw materials that need to be pre - formed and compact the concrete raw materials into a formed shape. Structurally, the mold - making machine includes a mold - making frame 1. A support base 2 is connected to the mold - making frame 1. A number of parallel - arranged profiled steels 3 are installed and connected to the top surface of the support base 2. A bottom plate 4 for supporting the concrete raw materials is placed on the top surface of the profiled steel 3. Side plates 5 for supporting and limiting the concrete raw materials are arranged around the bottom plate 4. A compaction plate 6 for compacting the concrete raw materials on the bottom plate 4 is movably arranged above the bottom plate 4. In the embodiment, when it is necessary to pre - cast and compact the required concrete precast blocks, the concrete raw materials are poured onto the bottom plate 4 of the mold - making machine. Since side plates 5 (equivalent to side molds) are respectively installed around the bottom plate 4 to prevent the concrete raw materials from falling off the bottom plate 4, and then by controlling the compaction plate 6 to move downward towards the bottom plate 4, the concrete raw materials on the bottom plate 4 are compacted into a formed shape, so as to achieve the purpose of rapid compaction and forming. Among them, a number of holes are provided in the set bottom plate 4 for the moisture in the concrete raw materials to pass through, and the set profiled steel 3 is used to make the bottom plate 4 in a "semi - empty setting" so that the moisture can pass through the holes more quickly and fully, and the compacted concrete precast blocks can be quickly cured and formed.

[0025] Furthermore, in the embodiment, a dividing frame 7 is also arranged between the compaction plate 6 and the bottom plate 4. The dividing frame 7 is arranged in a grid pattern. The dividing frame 7 is detachably connected to the compaction plate 6 by a screw thread; by arranging the dividing frame 7, the concrete raw materials on the bottom plate 4 can be divided into several smaller "precast blocks", so as to obtain the required smaller concrete precast blocks; if a whole concrete slab (block) is needed, only the dividing frame 7 needs to be removed from the compaction plate 6.

[0026] At the same time, one end of the compaction plate 7 away from the bottom plate 4 is connected to a conical - shaped movable seat 71, and the other end of the movable seat 71 is connected to a movable top frame 72; a channel tube for the concrete raw materials to pass through is arranged on the movable top frame 72, and the other end of the channel tube passes through the compaction plate 6 for the concrete raw materials to fall onto the bottom plate 4; the advantage of such a design is that the concrete raw materials can be quickly introduced onto the bottom plate 4, reducing the spillage of the concrete raw materials and saving raw materials.

[0027] Furthermore, in the embodiment, lifting mechanisms for driving the lifting and moving of the movable top frame 72 are respectively arranged at both ends of the movable top frame 72; each lifting mechanism includes a hydraulic lifting rod 8. One end of the hydraulic lifting rod 8 is hinged to the movable top frame 72 through a connecting block, and the other end of the hydraulic lifting rod 8 is installed and connected to a support base 2 connected to the mold-making machine frame 1. At the same time, sliding guide beams 73 are respectively arranged at both ends of the movable top frame 72. The sliding guide beams 73 are connected to the movable top frame 72 through connecting beams, and the sliding guide beams 73 are slidably connected to the mold-making machine frame 1 in a liftable manner. When driving the movable top frame 72 to move downward towards the concrete raw material on the bottom plate 1 by controlling the hydraulic lifting rod 8, and under the "sliding and guiding" action of the two sliding guide beams 73, when there is a dividing frame 7, the dividing frame 7 divides the concrete raw material on the bottom plate 4 into several smaller concrete precast blocks, and then the compaction plate 6 compacts the concrete on the bottom plate 4; and, in order to ensure the density quality of the compacted and formed concrete precast blocks, a vibration motor is also installed on the movable top frame 72. The output end of the vibration motor is hinged to the movable top frame 72 through a hinge seat, and the outer shell of the vibration motor is fixedly connected to the mold-making machine frame 1 through bolts; by controlling the vibration motor to drive the movable top frame 72 to "vibrate actively", thereby driving the compaction plate 6 to vibrate and compact the concrete on the bottom plate 4, and ensuring the density quality of the formed concrete precast blocks.

[0028] Generally speaking, this mold-making machine is used to replace the original customized steel molds or wooden molds, support the concrete raw materials that need to be preformed, and compact the concrete raw materials into the required concrete precast blocks, so as to achieve the purpose of rapid forming, improve the efficiency of preforming, and save time and costs.

[0029] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention; at the same time, any arbitrary combinations can be made between various different embodiments of the present invention, as long as they do not violate the idea of the present invention, and they shall also be regarded as the content disclosed by the present invention.
