Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete forming, in particular to an energy-saving, environment-friendly and reusable mold for precast concrete components of expressways. BACKGROUND

[0002] With the rapid expansion of the expressway network in China, precast concrete components (such as box girders, T-beams, guardrail plates, drainage channels, etc.) have become the core supporting technology for modern expressway construction due to their high standardization, fast on-site construction, and strong quality controllability. Currently, the industry generally uses steel molds for factory precast production through processes such as concrete pouring, vibration compaction, and steam curing to form components.

[0003] Traditional molds rely on attached vibrators to achieve concrete compaction. Due to the complexity of the mold structure (such as dense reinforcement areas and chamfered parts) and the operating space, it is difficult for the vibration energy to be uniformly transmitted to the interior of the concrete. Especially in high-strength reinforcement areas, the vibration resistance increases and energy consumption is high; if an inserted vibration rod is used, the hole left by the vibration rod needs to be addressed when it is withdrawn.

[0004] In addition, due to the easy deformation and wear of the mold, the recycling rate is low after repeated use and scrapping.

[0005] Therefore, it is necessary to provide an energy-saving, environment-friendly, and reusable mold for precast concrete components of expressways to solve the above problems. SUMMARY

It should be understood that terms so used are interchangeable under appropriate circumstances and are merely employed in the descriptions of embodiments of the present application for purposes of the description.

[0040] Embodiment: Please refer to Figures 1-4 In the embodiment of the present application, an energy-saving, environment-friendly and reusable mold for precast concrete components of expressway is provided, comprising:

[0041] a base 9;

[0042] a mold 5, which is internally provided with a through forming cavity in the length direction, and is used for prepositioning a steel reinforcement cage and filling concrete;

[0043] a vibrating frame 8, which is fixedly connected with the mold 5 at the top end and is elastically connected with the base 9 at the bottom end through a first spring 10, and is provided with a first vibrator 11 fixedly connected thereto, which is used for implementing overall vibration on the concrete in the mold 5;

[0044] a cover 7, which is blocked at one axial end of the forming cavity and is provided with a reserved passage for the end of the steel reinforcement cage to pass out;

[0045] a steel reinforcement vibration assembly 6, which is assembled on the base 9 and is used for blocking the end of the forming cavity away from the cover 7 and implementing vibration excitation on the steel reinforcement cage.

[0046] In the preparation of the precast reinforced concrete component, the cover 7 is first opened and the steel reinforcement cage is lowered into the mold 5, then the cover 7 is reset, wherein the end of the steel reinforcement cage passes out of the reserved passage of the cover 7, at this time, the concrete is injected into the mold 5, during the injection, the first vibrator 11 continuously performs overall vibration to improve the compactness of the concrete, after the injection of the concrete is completed, the first vibrator 11 stops working, at this time, the steel reinforcement vibration assembly 6 implements vibration excitation on the steel reinforcement cage, thereby realizing vibration treatment around the steel reinforcement cage and improving the compactness between the steel reinforcement cage and the concrete.

[0047] Specifically, the steel reinforcement vibration assembly 6 comprises:

[0048] a side seat 61, which is fixedly connected with the base 9;

[0049] a vibrating bin 63, which is elastically connected with the side seat 61 through an elastic member 62;

[0050] The steel bar positioning assembly blocks one end of the forming cavity and positions the steel bar cage, and the other end is detachably connected with the vibration bin 63 through the quick release head 612;

[0051] The second vibrator 613 is fixed to the outer wall of the vibration bin 63.

[0052] The side seat 61 is fixed to the base 9 and serves as the mounting base of the steel bar vibration assembly 6. Since the second vibrator 613 only performs small amplitude vibration, the elastic member 62 can provide small amplitude deformation and reset after deformation, for example, using elastic rubber material.

[0053] Further, the steel bar positioning assembly comprises:

[0054] The positioning groove 64 is connected with the side wall of the vibration bin 63 through the quick release head 612, and the axial end of the positioning groove 64 forms a notch structure;

[0055] The sealing cylinder 66 is elastically connected with the positioning groove 64 through the elastic ring 65, and the other end is sealingly connected with the end of the mold 5. The elastic ring 65 can be made of the same material as the elastic member 62.

[0056] The sealing disc 67 is fixedly arranged in the inner cavity of the sealing cylinder 66, and a plurality of positioning holes 68 adapted to the steel bar cage are formed in the sealing disc 67.

[0057] When the steel bar cage is lowered into the mold 5, the end of the steel bar cage passes through the positioning hole 68 and enters the positioning groove 64.

[0058] The vibration sleeve 69 is arranged in the positioning groove 64 corresponding to the position of each positioning hole 68. The vibration sleeve 69 is connected with the inner wall of the positioning groove 64 through the second spring 610, and the adjacent two vibration sleeves 69 are selectively connected through the second spring 610.

[0059] Specifically, each vibration sleeve 69 is connected with the inner wall of the positioning groove 64 through the second spring 610, and the adjacent two vibration sleeves 69 can be connected through the second spring 610 or not connected, but the premise of not connecting the adjacent two vibration sleeves 69 is to ensure that any vibration sleeve 69 is not suspended, for example, the vibration sleeve 69 at the middle must be connected with at least one adjacent vibration sleeve 69 through the second spring 610, otherwise the vibration sleeve 69 at the middle is suspended, which is not realized. Figure 4

[0060] ​In addition, when the second vibrator 613 is started, the vibration bin 63 is vibrated and transmitted to the vibration sleeve 69 through the second spring 610, and then transmitted to the reinforcement cage through the vibration sleeve 69.

[0061] When the vibration bin 63 shakes, the second spring 610 absorbs kinetic energy by deformation, so that the shaking amplitude of the vibration sleeve 69 is smaller than that of the vibration bin 63; when the vibration bin 63 stops shaking, the second spring 610 releases elastic potential energy, so that the vibration sleeve 69 continues to shake.

[0062] Preferably, the reserved passage on the cover 7 and the inner wall of the positioning hole 68 on the sealing disc 67 are both provided with elastic sealing rings.

[0063] Preferably, the bottom of the positioning groove 64 is communicated with an inlet and outlet pipe 611, and the inlet and outlet pipe 611 is connected with a liquid pump.

[0064] The liquid pump can inject some liquid into the positioning groove 64, and the liquid changes the dynamic characteristics of the system by viscous resistance and additional mass effect, so that the shaking amplitude of the vibration sleeve 69 is closer to that of the vibration bin 63.

[0065] In this embodiment, a grouting assembly is further included, which comprises:

[0066] A feeding bin 1, in which a plurality of concrete raw materials are pre-stored;

[0067] A mixing bin 2, which receives the concrete raw materials from the feeding bin 1 and mixes them;

[0068] A lifting bin 3, the feeding end of which is communicated with the mixing bin 2, and the discharging end of which is arranged at a high position;

[0069] A grouting bin 4, the top of which is communicated with the discharging end of the lifting bin 3, and the bottom of which is communicated with the forming cavity of the mold 5 through a flexible pipe.

[0070] In addition, the grouting bin 4 is provided with a spiral stirring mechanism, and the top of the grouting bin 4 is provided with an exhaust hole.

[0071] In the implementation, the plurality of concrete raw materials pre-stored in the feeding bin 1 are discharged into the mixing bin 2 according to a preset ratio and order. The mixing bin 2 fully stirs and mixes the entering concrete raw materials, so that the various raw materials are uniformly 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 to continuously stir the concrete to prevent it from segregating; at the same time, the exhaust hole at the top of the grouting bin 4 exhausts the gas generated in the grouting process. The stirred concrete flows into the forming cavity of the mold through the flexible pipe at the bottom of the grouting bin 4 under the action of gravity, the grouting process is completed, and the molded product can be obtained after the concrete solidifies.

[0072] The above description is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent substitutions or changes according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
