Description

Technical Field

[0001] This utility model relates to the field of concrete technology, specifically to a molding device for ultra-high performance concrete structures. Background Technology

[0002] Ultra-high performance concrete (UHPC) is a new type of building material, typically made of cement, silicates, quartz powder, mineral admixtures, and chemical additives. It possesses extremely high compressive strength, often exceeding 150 MPa. However, despite its excellent compressive strength, UHPC's flexural strength is relatively insufficient, limiting its application in structures requiring bending stress.

[0003] In related technologies, steel fibers are often incorporated into UHPC to improve its flexural strength, thereby enhancing its tensile and crack resistance. Studies have shown that the directional arrangement of steel fibers in concrete has a significant effect on improving its flexural strength. However, traditional steel fiber orientation techniques have certain limitations, mainly in the following aspects:

[0004] 1. Magnetic field orientation technology: This method involves applying an external magnetic field during concrete pouring to align steel fibers along the direction of the magnetic field. However, this method requires adding magnetized steel fibers to the concrete and applying an external magnetic field to control the fiber orientation. This increases the complexity and cost of the materials and is difficult to operate, making it difficult to promote and apply in practical engineering.

[0005] 2. Flow-induced method: This method involves mixing steel fibers with concrete slurry, utilizing the fluidity of the concrete slurry to induce the steel fibers to oriented. However, the orientation of the steel fibers is affected by the fluidity of the concrete slurry, especially when the steel fiber content is high, fiber agglomeration is likely to occur, preventing effective oriented alignment of the steel fibers and thus affecting the mechanical properties of UHPC. Moreover, the amount of steel fiber is also limited, making it difficult to meet the requirements for improving flexural strength.

[0006] Therefore, how to easily and efficiently achieve the directional arrangement of steel fibers to form ultra-high performance concrete structures with ultra-high flexural strength is one of the urgent problems to be solved. Utility Model Content

[0007] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a molding device for ultra-high performance concrete structures, which solves the technical problems of high material costs, high operation difficulty, easy agglomeration of steel fibers and difficulty in achieving directional arrangement, and limited flexural strength of concrete structures in the molding of ultra-high performance concrete structures.

[0008] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0009] This utility model provides a molding device for ultra-high performance concrete structures, including:

[0020] In some embodiments, the steel fiber discharge member is inclined, and an elastic buffer is also provided at the outlet of the steel fiber discharge member.

[0034] The second driving component is disposed on the sliding track and is connected to the concrete slurry pouring mechanism for driving the concrete slurry pouring mechanism to slide along the sliding track.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0039] To address the aforementioned technical problems, this utility model provides a molding device for ultra-high performance concrete structures, which not only reduces the molding difficulty of ultra-high performance concrete structures and greatly improves their molding efficiency, but also prevents steel fibers from agglomerating in the concrete slurry, thereby effectively improving the flexural strength of ultra-high performance concrete structures.

[0040] Please see Figure 1 , Figure 1 This is a schematic diagram of the overall structure of the molding device for ultra-high performance concrete structure in one embodiment of the present invention. The molding device for ultra-high performance concrete structure includes a base plate 1, a vibration platform 2, a steel fiber arrangement mechanism 3, and a concrete slurry pouring mechanism 4. The vibration platform 2, the steel fiber arrangement mechanism 3, and the concrete slurry pouring mechanism 4 can all be set on the base plate 1.

[0041] The vibration platform 2 can be equipped with a casting mold (not shown in the figure) for concrete casting; the steel fiber arrangement mechanism 3 can orient and transport multiple steel fibers into the casting mold; and the concrete slurry casting mechanism 4 can cast ultra-high performance concrete into the casting mold, so that it forms an ultra-high performance concrete structure with ultra-high flexural strength with multiple steel fibers.

[0042] Specifically, the aforementioned vibration platform 2 can be installed as a whole on the base plate 1, and the casting mold can be set on its upper surface. The vibration platform 2 includes a vibration table 21, a first vibration device 22, and a fixing mechanism 23; the vibration table 21 is used to support and install the casting mold; the function of the first vibration device 22 is to vibrate the casting mold so that the concrete slurry and steel fibers can be fully combined; and the function of the fixing mechanism 23 is to fix the casting mold and prevent the casting mold from falling off during vibration.

[0043] The first vibration device 22 can be any device with vibration function. For example, in one embodiment, the first vibration device 22 can be a vibration motor, which can be fixedly installed at the bottom of the vibration table 21.

[0044] The aforementioned fixing mechanism 23 can be any mechanism with clamping and fixing functions. For example, in one embodiment, the fixing mechanism 23 can be two sets of oppositely arranged cylinders or hydraulic cylinders. The two sets of cylinders or hydraulic cylinders can respectively press against the opposite sides of the casting mold, thereby achieving the fixing effect on the casting mold.

[0045] In another embodiment, the aforementioned fixing mechanism 23 is rotatably mounted on the vibration table 21. To achieve this, a turntable (not shown in the figure) can be additionally added to the vibration table 21, and the fixing mechanism 23 can be entirely mounted on this turntable. Simultaneously, a rotary drive component can be correspondingly mounted on the vibration table 21. This rotary drive component can be a motor, which can be connected to the turntable via a gear mechanism or other similar transmission mechanism. Thus, the rotary drive component can drive the turntable to rotate, and the fixing mechanism 23 can drive the casting mold to rotate synchronously. In this way, not only can the orientation of the casting mold be effectively adjusted, but the arrangement direction of the steel fibers in the casting mold can also be easily adjusted.

[0046] It is understood that the above-mentioned casting mold is used to cast the required ultra-high performance concrete structure, and its specific shape can be determined according to the ultra-high performance concrete structure required in the design. At the same time, in conjunction with the detachable fixing method adopted by the fixing mechanism 23 in this embodiment for the casting mold, in actual applications, the casting mold on the vibration platform 2 can also be replaced as needed to cope with changes in the concrete structure or damage to the original casting mold.

[0047] Please see Figure 1 In this embodiment, the steel fiber arrangement mechanism 3 can be integrally installed on one side of the vibration platform 2, and includes a bottom support 31, a steel fiber silo 32, and a second vibration device 33. The bottom support 31 can be used to support the steel fiber silo 32, the steel fiber silo 32 is used to store spare steel fibers, and the second vibration device 33 is used to vibrate the steel fiber silo 32.

[0048] Specifically, the bottom support 31 is entirely mounted on the aforementioned base plate 1, while the steel fiber hopper 32 is entirely mounted on the bottom support 31. The top of the steel fiber hopper 32 is open to allow steel fibers to enter, and an outlet is provided at the bottom for the steel fibers to exit. To facilitate the entry of steel fibers into the steel fiber hopper 32, the opening at the top of the steel fiber hopper 32 can be designed in a funnel-like structure.

[0049] The second vibration device 33 can also be any device with vibration function. For example, in one embodiment, the second vibration device 33 can also be a vibration motor, which can be fixed on the outer wall of the steel fiber silo 32 to ensure the vibration effect.

[0050] In one embodiment, to ensure the orderly discharge of steel fibers, a screen 34 can be provided inside the steel fiber silo 32. The screen 34 can be horizontally fixed inside the steel fiber silo 32 near its top opening. Multiple screen holes are formed on the screen 34. When multiple steel fibers are simultaneously fed into the steel fiber silo 32, they will be combed and ordered as they pass through the multiple screen holes.

[0051] In this embodiment, the steel fiber arranging mechanism 3 further includes a transmission assembly 35 disposed on the bottom support 31 and a steel fiber discharge component 36 connected to the transmission assembly 35. The steel fibers discharged from the steel fiber hopper 32 first fall onto the transmission assembly 35, which then further transmits the steel fibers to the steel fiber discharge component 36; finally, the steel fibers are discharged from the outlet of the steel fiber discharge component 36 and fall into the casting mold.

[0052] Specifically, the aforementioned transmission component 35 can be any component with a conveying function. For example, in one embodiment, the transmission component 35 can be a belt conveyor mechanism, which is set between the steel fiber hopper 32 and the steel fiber discharge component 36 to realize the conveying function of steel fibers.

[0053] To achieve the directional arrangement of multiple steel fibers, multiple directional grooves 351 can be provided on the belt conveyor mechanism. The multiple directional grooves 351 are arranged in the same direction and side by side on the belt. When the steel fibers are discharged from the steel fiber hopper 32 and fall onto the belt, they will adjust their state by themselves and fall into each directional groove 351 under the vibration action of the second vibration device 33, thereby achieving directional arrangement.

[0054] The aforementioned steel fiber discharge component 36 is located on the side of the conveying assembly 35 away from the steel fiber hopper 32, and it can be an inclined slide. When the conveying assembly 35 conveys the steel fiber to its end, the steel fiber will fall onto the slide and slide into the casting mold.

[0055] In another embodiment, to further improve the orderly arrangement of steel fibers within the casting mold, an elastic buffer (not shown in the figure) can be provided at the outlet of the steel fiber outlet 36. This elastic buffer can be a rubber strip or other similar material, and can be positioned on the side of the steel fiber outlet 36 closest to the casting mold. Thus, when the steel fibers slide down the steel fiber outlet 36 to the position of the elastic buffer, the buffering effect of the elastic buffer will slow the steel fibers as they fall into the casting mold, preventing them from changing direction or colliding with each other.

[0056] Please see Figure 1 In this embodiment, the concrete slurry pouring mechanism 4 can be set as a whole on one side of the vibration platform 2. Preferably, the concrete slurry pouring mechanism 4 and the steel fiber arrangement mechanism 3 can be set on opposite sides of the vibration platform 2 respectively. Its main function is to pour concrete slurry into the pouring mold.

[0057] Specifically, the concrete slurry pouring mechanism 4 includes a fixed frame 41, a concrete slurry silo 42, a concrete discharge device 43, and a third vibration device 44. The fixed frame 41 is installed on the base plate 1, the concrete slurry silo 42 is erected on the fixed frame 41 and connected to the concrete discharge device 43, and the third vibration device 44 is connected to the concrete slurry silo 42 for vibrating the concrete slurry silo 42.

[0058] The aforementioned concrete slurry silo 42 is mainly used to store spare concrete slurry, and it is open on both the top and bottom. The top opening of the concrete slurry silo 42 can also be designed to be wider at the top and narrower at the bottom, forming a funnel-like structure to facilitate the addition of spare concrete slurry into the silo 42. The bottom opening of the concrete slurry silo can be connected to the aforementioned concrete discharge device 43 for discharging concrete slurry.

[0059] The concrete discharge component 43 is connected to the opening at the bottom of the concrete slurry silo 42 and is used to discharge concrete slurry. It can be any component with discharge function. For example, in one embodiment, the concrete discharge component 43 can be a long, straight, flat pipe. The pipe can be fixedly connected to the outlet of the concrete slurry silo 42 and is set at an angle downward to facilitate the discharge of concrete slurry.

[0060] In another embodiment, a discharge speed adjustment mechanism 45 may also be provided on the concrete discharge member 43. The discharge speed adjustment mechanism 45 can be any mechanism that can control the size of the outlet of the concrete discharge member 43, such as a movable valve. By means of the discharge speed adjustment mechanism 45 provided on the concrete discharge member 43, the pouring speed of the concrete slurry can be effectively controlled, thereby indirectly ensuring the molding quality.

[0061] The aforementioned third vibration device 44 can be any device with vibration function. For example, in one embodiment, the third vibration device 44 can also be a vibration motor, which can be fixed to the outer wall of the concrete slurry silo 42. When the third vibration device 44 is started, it can fully vibrate the concrete slurry, preventing the concrete slurry from solidifying inside the concrete slurry silo 42.

[0062] Please see Figure 1 In this embodiment, the molding device for the ultra-high performance concrete structure also includes a sliding drive mechanism, which can be used to drive the steel fiber arrangement mechanism 3 and the concrete slurry pouring mechanism 4 to move, so as to facilitate the laying of the steel fiber layer and the uniform pouring of the concrete slurry layer.

[0063] Specifically, the sliding drive mechanism includes a sliding track 5, a first drive component 6, and a second drive component 7. The sliding track 5 is integrally mounted on the base plate 1 and serves to support the steel fiber arrangement mechanism 3 and the concrete slurry pouring mechanism 4. The first drive component 6 is driveably connected to the steel fiber arrangement mechanism 3 and drives the steel fiber arrangement mechanism 3 to move along the sliding track 5. The second drive component 7 is driveably connected to the concrete slurry pouring mechanism 4 and drives the concrete slurry pouring mechanism 4 to move along the sliding track 5.

[0064] Since the movement of the steel fiber arrangement mechanism 3 and the concrete slurry pouring mechanism 4 is not synchronized during actual operation, the above-mentioned sliding track 5 can be divided into a first track 51 and a second track 52. Both the first track 51 and the second track 52 are fixedly and horizontally mounted on the base plate 1. The first track 51 can be used to support the steel fiber arrangement mechanism 3, and the second track 52 can be used to support the concrete slurry pouring mechanism 4. The first track 51 and the second track 52 can be set in the same direction.

[0065] Specifically, the bottom of the aforementioned bottom support 31 can be slidably connected to the first track 51 via a slider, thereby allowing the steel fiber arrangement mechanism 3 to move along the first track 51. Similarly, the bottom of the aforementioned fixed frame 41 can be slidably connected to the second track 52 via a slider, thereby allowing the concrete slurry pouring mechanism 4 to move along the second track 52.

[0066] The first driving component 6 can be a stepper motor or other motor. The first driving component 6 can be connected to the slider on the bottom bracket 31 through a lead screw, so that the first driving component 6 can drive the steel fiber arrangement structure.

[0067] Similarly, the second driving component 7 mentioned above can also be a stepper motor or other motor, and its configuration can be the same as that of the first driving component 6, which will not be described in detail here.

[0068] To better understand this utility model, the following is combined with... Figure 1 The technical solution of this utility model is described in detail below:

[0069] In practical applications, workers can first fix the casting mold on the vibrating table 21, and then control the steel fiber arrangement mechanism 3 and the concrete slurry casting mechanism 4 to move the vibrating table 21 through the sliding drive mechanism, so that the outlet of the steel fiber discharge part 36 and the outlet of the concrete discharge part 43 both extend to the position of the casting mold.

[0070] At this time, under the action of the second vibration device 33, the steel fibers fall onto the transmission component 35 and are oriented in the multiple orientation grooves 351 on the transmission component 35. Subsequently, the transmission component 35 transmits the oriented steel fibers to the steel fiber discharge component 36, allowing them to be discharged through the outlet of the steel fiber discharge component 36. During this process, the first driving component 6 drives the steel fiber arrangement mechanism 3 to move along the first track 51, thereby enabling the steel fibers to be laid sequentially in the casting mold to form a steel fiber layer.

[0071] Next, under the action of the second drive member 7, the concrete slurry pouring mechanism 4 will move along the second track 52 and pour concrete slurry into the pouring mold in sequence, forming a concrete slurry layer on the steel fiber layer.

[0072] Subsequently, under the vibration of the first vibration device 22 on the vibration table 21, the concrete slurry layer gradually seeps into the underlying steel fiber layer and fully fills the gaps in the steel fiber layer. Next, the above steps are repeated until the ultra-high performance concrete structure is poured.

[0073] This method enables the automatic orientation and arrangement of steel fibers, which not only reduces the molding difficulty of ultra-high performance concrete structures and greatly improves their molding efficiency, but also prevents steel fibers from agglomerating in the concrete slurry, thereby effectively improving the flexural strength of ultra-high performance concrete structures.
