Description

Technical Field

[0001] The invention relates to the technical field of concrete molding, and in particular to an energy-saving, environmentally friendly and reusable highway precast concrete component mold. Background Art

[0002] With the rapid expansion of my country's expressway network, precast concrete components (such as box girders, T-beams, guardrails, and gutters) have become a core supporting technology for modern expressway construction due to their advantages of high standardization, fast on-site construction, and strong quality control. Currently, the industry generally uses steel molds for factory prefabrication, forming components through processes such as concrete pouring, vibrating and compacting, and steam curing.

[0003] Traditional molds rely on attached vibrators to achieve concrete densification. Limited by the mold's structural complexity (e.g., areas with dense rebar and chamfers) and limited operating space, vibration energy cannot be evenly transmitted throughout the concrete. Vibration resistance is particularly high in areas with high-strength rebar, leading to high energy consumption. Furthermore, using an inserted vibrator requires the removal of holes left behind by the vibrator.

[0004] In addition, since the mold is easily deformed and worn, the recycling rate after repeated use is low.

[0005] Therefore, it is necessary to provide an energy-saving, environmentally friendly and reusable highway precast concrete component mold to solve the above problems. Summary of the Invention

[0006] To solve the above problems, the present invention provides the following technical solution: an energy-saving, environmentally friendly and reusable highway precast concrete component mold, comprising: base; The mold has a through-molding cavity along its length, and the molding cavity is used to pre-place a steel skeleton and fill it with concrete; a vibration frame, the top end of which is fixedly connected to the mold and the bottom end of which is elastically connected to the base via a first spring; a first vibrator is fixedly connected to the vibration frame for vibrating the concrete in the mold as a whole; A sealing cover, which blocks one axial end of the forming cavity and is provided with a reserved passage for the end of the steel bar skeleton to pass through; The steel bar vibration component is assembled on the base and is used to block the end of the forming cavity away from the cover and to implement vibration excitation on the steel bar skeleton.

[0007] Furthermore, preferably, the steel bar vibration assembly includes: a side seat fixedly connected to the base; a vibration chamber elastically connected to the side seat via an elastic member; A steel bar positioning assembly, one end of which blocks the end of the forming cavity and positions the steel bar skeleton, and the other end of which is detachably connected to the vibration chamber via a quick-release head; The second vibrator is fixed on the outer wall of the vibration chamber.

[0008] Furthermore, preferably, the steel bar positioning assembly includes: A positioning groove, which is connected to the side wall of the vibration chamber through the quick-release head, and the axial end of the positioning groove forms a notch structure; A sealing cylinder, which is elastically connected to the positioning groove through an elastic ring, and the other end of which is sealingly sleeved on the end of the mold; The sealing disk is fixedly arranged in the inner cavity of the sealing cylinder, and a plurality of positioning holes adapted to the steel frame are provided on the sealing disk.

[0009] Furthermore, preferably, a vibration sleeve is arranged in the positioning groove corresponding to each positioning hole position, the vibration sleeve is connected to the inner wall of the positioning groove through a second spring, and two adjacent vibration sleeves are selectively connected through the second spring.

[0010] Furthermore, preferably, the reserved channel on the cover and the inner wall of the positioning hole on the sealing disk are both provided with elastic sealing rings.

[0011] Furthermore, preferably, the bottom of the positioning groove is connected with an inlet and outlet pipe, and the inlet and outlet pipe is externally connected to a liquid pump.

[0012] Furthermore, as an advantage, it further comprises a grouting assembly, the grouting assembly comprising: The unloading silo contains a variety of concrete raw materials; A mixing silo that receives concrete raw materials from the lower silo and mixes them; The lifting bin has a feeding end connected to the mixing bin and a discharging end arranged at a high position; The top of the grouting bin is connected with the discharge end of the lifting bin, and the bottom is connected with the mold forming cavity through a flexible pipe.

[0014] Compared with the existing technology, the present invention provides an energy-saving, environmentally friendly and reusable highway precast concrete component mold, which has the following beneficial effects: In the present invention, the mold, cover, and steel bar positioning assembly can all be replaced independently. There is no need to adjust other components during replacement, ensuring the reuse of core components and significantly improving overall versatility and cost-effectiveness.

[0015] In this invention, during grouting, the first vibrator vibrates the entire concrete within the mold, compacting it, reducing internal voids, and improving the strength and durability of the component. After the concrete is poured, the rebar vibration assembly vibrates the rebar skeleton, further strengthening the bond between the rebar skeleton and the concrete, ensuring overall component quality while minimizing energy consumption.

[0022] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned description of the drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, and this is merely a way of distinguishing the objects of the same attributes when describing them in the embodiments of the present application. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, so that the process, method, system, product or equipment comprising a series of units need not be limited to those units, but may include other units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0023] Example: Please refer to Figures 1-4 In an embodiment of the present invention, an energy-saving, environmentally friendly and reusable highway precast concrete component mold is provided, comprising: Base 9; The mold 5 has a through-molding cavity along its length, which is used to pre-place a steel bar skeleton and fill it with concrete; A vibration frame 8, the top of which is fixedly connected to the mold 5, and the bottom of which is elastically connected to the base 9 via a first spring 10. A first vibrator 11 is fixedly connected to the vibration frame 8 for vibrating the concrete in the mold 5 as a whole; A cover 7, which blocks one axial end of the forming cavity and is provided with a reserved passage for the end of the steel bar skeleton to pass through; The steel bar vibration assembly 6 is assembled on the base 9 and is used to block the end of the forming cavity away from the cover 7 and implement vibration excitation on the steel bar skeleton.

[0024] When preparing reinforced concrete prefabricated components, first open the cover 7 and lower the steel skeleton into the mold 5, then reset the cover 7, with the end of the steel skeleton passing through the reserved channel of the cover 7, and then inject concrete into the mold 5. During the injection, the first vibrator 11 continuously vibrates as a whole to improve the compactness of the concrete. After the concrete is injected, the first vibrator 11 stops working. At this time, the steel vibration component 6 implements vibration excitation on the steel skeleton, thereby realizing vibration treatment around the steel skeleton, and improving the compactness between the steel skeleton and the concrete.

[0025] Specifically, the steel bar vibration component 6 includes: A side seat 61 is fixed to the base 9; a vibration chamber 63 , which is elastically connected to the side seat 61 via an elastic member 62 ; A steel bar positioning assembly, one end of which blocks the end of the forming cavity and positions the steel bar skeleton, and the other end of which is detachably connected to the vibration chamber 63 via a quick-release head 612; The second vibrator 613 is fixed to the outer wall of the vibration chamber 63 .

[0026] The side seat 61 is fixed to the base 9 and serves as the installation base of the steel bar vibration component 6. Since the second vibrator 613 only vibrates with a small amplitude, the elastic member 62 can only provide a small amplitude deformation and reset after deformation, for example, using an elastic rubber material.

[0027] Furthermore, the steel bar positioning assembly includes: The positioning groove 64 is connected to the side wall of the vibration chamber 63 through the quick-release head 612, and the axial end of the positioning groove 64 forms a notch structure; A sealing cylinder 66 is elastically connected to the positioning groove 64 through an elastic ring 65, and the other end is sealingly sleeved on the end of the mold 5. The elastic ring 65 can be made of the same material as the elastic member 62; The sealing disk 67 is fixedly mounted in the inner cavity of the sealing cylinder 66 , and a plurality of positioning holes 68 adapted to the steel frame are provided on the sealing disk 67 .

[0028] When the steel bar skeleton is lowered into the mold 5 , the end of the steel bar skeleton will pass through the positioning hole 68 and enter the positioning groove 64 .

[0029] A vibration sleeve 69 is arranged in the positioning groove 64 at a position corresponding to each positioning hole 68 . The vibration sleeve 69 is connected to the inner wall of the positioning groove 64 via a second spring 610 , and two adjacent vibration sleeves 69 are selectively connected via the second spring 610 .

[0030] Specifically, each of the vibration sleeves 69 is connected to the inner wall of the positioning groove 64 through the second spring 610. The adjacent two vibration sleeves 69 can be connected through the second spring 610 or the adjacent two vibration sleeves 69 are not connected. However, the premise of the adjacent two vibration sleeves 69 not being connected is to ensure that any one of the vibration sleeves 69 is not suspended. For example, Figure 4 In the embodiment, the vibration sleeve 69 located in the middle must be connected to at least one adjacent vibration sleeve 69 through the second spring 610, otherwise the vibration sleeve 69 located in the middle will be suspended, which is impossible to achieve.

[0031] In addition, during implementation, when the second vibrator 613 is started, the vibration chamber 63 vibrates accordingly, and is transmitted to the vibration sleeve 69 through the second spring 610, and then accurately transmitted to the steel frame through the vibration sleeve 69.

[0032] When the vibration chamber 63 shakes, the second spring 610 absorbs kinetic energy by deformation, so that the vibration sleeve 69 shakes less than the vibration chamber 63; when the vibration chamber 63 stops shaking, the second spring 610 releases elastic potential energy, allowing the vibration sleeve 69 to continue shaking.

[0033] Preferably, the reserved channel on the cover 7 and the inner wall of the positioning hole 68 on the sealing disk 67 are both provided with elastic sealing rings.

[0034] Preferably, the bottom of the positioning groove 64 is connected to an inlet and outlet pipe 611, and the inlet and outlet pipe 611 is connected to an external liquid pump.

[0035] Some liquid can be injected into the positioning groove 64 through a liquid pump. The liquid significantly changes the dynamic characteristics of the system through viscous resistance and added mass effect, so that the shaking amplitude of the vibration sleeve 69 is closer to that of the vibration chamber 63.

[0036] In this embodiment, a grouting assembly is also included, and the grouting assembly includes: A feed bin 1, in which a variety of concrete raw materials are pre-stored; Mixing bin 2, which receives concrete raw materials from lower bin 1 and mixes them; The lifting bin 3 has a feeding end connected to the mixing bin 2 and a discharging end arranged at a high position; The top of the grouting bin 4 is connected to the discharge end of the lifting bin 3, and the bottom is connected to the molding cavity of the mold 5 through a flexible pipe.

[0037] In addition, a spiral stirring mechanism is provided in the grouting bin 4, and an exhaust hole is provided on the top of the grouting bin 4.

[0038] During implementation, the various concrete raw materials pre-stored in the discharge bin 1 are discharged into the mixing bin 2 according to the preset proportions and sequence. The mixing bin 2 fully stirs and mixes the incoming concrete raw materials so that the various raw materials are evenly dispersed to form concrete with stable quality. The mixed concrete enters the lifting bin 3 from the mixing bin 2, and the lifting bin 3 lifts the concrete to a high position. The concrete in the high-position lifting bin flows into the grouting bin 4, and the spiral stirring mechanism in the grouting bin 4 starts to work, continuously stirring the concrete to prevent it from segregating; at the same time, the exhaust hole at the top of the grouting bin 4 discharges the gas generated during the grouting process. Under the action of gravity, the mixed concrete flows into the molding cavity of the mold through the flexible pipe at the bottom of the grouting bin 4, completing the grouting process. After the concrete solidifies, the molded product can be obtained.

[0039] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, which should be covered by the scope of protection of the present invention.
