Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of building material production equipment, and more particularly, to a casting mold for ultra-high performance concrete precast components. Background Art

[0002] In the construction field, with the continuous expansion of the scale of construction projects and the increasing requirements for construction quality, ultra-high performance concrete precast components are increasingly widely used. For the casting of large concrete precast components, detachable large plate molds are usually used.

[0003] However, this traditional mold structure has some significant problems. To ensure the stability and integrity of the mold during the casting process, it is often necessary to penetrate and install connectors inside the mold for installation and reinforcement. However, this operation requires professional technicians to carefully plan to determine the optimal penetration position of the connectors. Even so, in actual construction, due to the limitations of the mold structure and construction conditions, it is often difficult to completely avoid the conflict between the penetration position of the connectors and the forming surface of the precast components.

[0004] This results in hole defects on the surface of the formed concrete precast components, which not only affect the appearance quality of the precast components, but may also weaken their structural strength and durability. These hole defects are likely to become the starting points of cracks during subsequent use, reducing the service life of the precast components. In addition, the repair of hole defects also requires additional time and cost, increasing the cost and construction period of the entire project. Summary of the Invention

[0005] To overcome the above defects, embodiments of the present disclosure provide a casting mold for ultra-high performance concrete precast components, which solves the technical problem that the through-type connectors used in the forming molds of concrete precast components in the related art may affect the structure of the formed concrete components.

Detailed implementation manners

[0042] The present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present disclosure, rather than limiting the present disclosure.

[0043] To make the drawings concise, only the parts related to the disclosure are schematically shown in each drawing, and they do not represent the actual structure of the product. In addition, to make the drawings concise and easy to understand, in some drawings, for components with the same structure or function, only one of them is schematically shown, or only one of them is marked. In this article, "one" not only means "only this one", but also means "more than one" situation, and "several" includes "two" and "more than two".

[0044] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific situations.

[0045] In the present disclosure, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "over" and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or only means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under" and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or only means that the horizontal height of the first feature is lower than that of the second feature.

[0046] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "left", and "right" are based on the orientation or positional relationships shown in the drawings. They are only for convenience of description and simplifying operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present disclosure.

[0047] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0048] As Figures 1 to 6 shown, it shows a casting mold for ultra-high performance concrete precast components in an embodiment of the present disclosure, including a first side plate 1; a second side plate 2 is arranged at an angle with the first side plate 1, and the second side plate 2 is slidably arranged on the first side plate 1. The first side plate 1 and the second side plate 2 are both arranged in pairs symmetrically. A forming space 101 is formed between the two first side plates 1 and the two second side plates 2; a forming bottom plate 3 is arranged to slide up and down in the forming space 101; a first pressing member 4 is arranged to slide up and down on the second side plate 2, and the first pressing member 4 is used to horizontally press the second side plate 2 and support the second side plate 2.

[0049] In this embodiment, the first side plate 1 arranged in pairs symmetrically and the slidably arranged second side plate 2 determine that the device is a combined-mode mold. In the initial state, there is a small distance reserved between the forming bottom plate 3 and the bottom of the forming space 101. During the pouring process, as the cement slurry is injected, the forming bottom plate 3 will slide down slightly. Due to the adsorption effect of the first side plate 1 and the second side plate 2 on the cement slurry, the vertical edges near their bottom edges will attach and stretch a part of the cement slurry in advance, achieving the effect of pre-coating the slurry at the edge seals where cavities may exist, and pre-filling and sealing the edge seals. At the same time, the first pressing member 4 gradually squeezes inward. This action avoids the situation where gaps are generated between the first side plate 1, the second side plate 2, and the forming bottom plate 3 during the sliding process of the forming bottom plate 3 and the gradual increase of the internal cement pressure, ensuring the sealing performance and stability of the mold.

[0050] Generally speaking, such a design, on the one hand, can make the assembly and disassembly of the mold more convenient. On the other hand, the initial reserved distance and the sliding action of the forming bottom plate 3, combined with the adsorption of the side plates on the slurry, effectively pre-fill the cavities that may exist at the edge seams, improving the sealing performance and overall quality of the precast components. Moreover, the gradual extrusion of the first pressing member 4 ensures that the side plates and the forming bottom plate are closely attached to each other during the pouring process, preventing the generation of gaps, avoiding concrete leakage and internal structural defects. It improves the working reliability and stability of the mold, reduces the defective rate of the precast components, and at the same time improves the construction efficiency and reduces the construction cost.

[0051] In some examples, a supporting outer frame 5 is further included. The supporting outer frame 5 has an outer frame bottom wall 501 and an outer frame side wall 502. The second side plate 2 is used to be placed on the outer frame bottom wall 501. One end of the first connecting rod 6 is hinged to the bottom of the forming bottom plate 3. The first sliding block 7 is horizontally slidably arranged on the outer frame bottom wall 501. One end of the first connecting rod 6 is hinged to the first sliding block 7. One end of the second connecting rod 8 is hinged to the first sliding block 7, and the other end is hinged to the first pressing member 4. One end of the third connecting rod 9 is hinged to the first pressing member 4. The abutting block 10 abuts against the outer frame side wall 502. The other end of the third connecting rod 9 is hinged to the abutting block 10. The forming bottom plate 3 is configured to drive the first pressing member 4 to slide upward and provide a force for the first pressing member 4 to move towards the forming space 101 after sliding down through the first connecting rod 6, the second connecting rod 8 and the third connecting rod 9.

[0052] In this embodiment, when the forming bottom plate 3 slides down, one end of the first connecting rod 6 hinged thereto descends. The other end of the first connecting rod 6 pushes the first sliding block 7 to slide horizontally. The sliding of the first sliding block 7 drives the first pressing member 4 to slide upward through the second connecting rod 8. At the same time, the first pressing member 4 pushes the abutting block 10 to tightly abut against the outer frame side wall 502 of the supporting outer frame 5 through the third connecting rod 9.

[0053] Since this device has a structure of external splicing for mold closing, the second side plate 2 is a long strip plate. As the total amount of internal cement increases, the second side plate 2 may undergo a small amount of deformation, affecting the sealing of the internal structure. During this process, the first pressing member 4 gradually moves towards the forming space 101, exerting an increasingly large supporting force on the second side plate 2. Especially for the second side plate 2 with a longer length, as the total amount of internal cement continues to increase, this supporting force can effectively offset the tendency of the internal pressure to expand the second side plate 2 outward, preventing it from deforming.

[0054] Generally speaking, first, the structure in this solution can automatically adjust the supporting force on the second side plate 2 according to the change in the total amount of cement in the forming space 101, achieving intelligent pressure balance adjustment without additional manual monitoring and operation. Second, especially for the second side plate 2 with a longer length, it provides stable and continuously enhanced shape structure support, effectively avoiding its possible deformation, ensuring the sealing of the internal structure of the mold, and ensuring that concrete will not leak during the pouring process, thereby improving the forming quality of precast components. Third, by maintaining the balance between internal and external pressures, the risk of damage to the mold caused by uneven pressure is significantly reduced. The stable and reliable structure support helps to improve the dimensional accuracy and surface flatness of precast components, enhance the market competitiveness of products, and at the same time provides a strong technical guarantee for the efficient and high-quality production of concrete precast components.

[0055] In some examples, a first elastic member 11 is further included. One end of the first elastic member 11 acts on the forming bottom plate 3, and the other end acts on the bottom wall 501 of the outer frame, providing a force in the direction away from the bottom wall 501 of the outer frame for the forming bottom plate 3.

[0056] In this embodiment, during the pouring process, when the forming bottom plate 3 slides downward under the pressure of the cement, the first elastic member 11 is compressed. When the cement pressure decreases or disappears, the elastic restoring force of the first elastic member 11 will push the forming bottom plate 3 away from the bottom wall 501 of the outer frame, making it return to the initial position or close to the initial position. The setting of the first elastic member 11 can provide a certain buffering effect for the forming bottom plate 3, reducing the impact and damage to the mold structure caused by the sudden increase in cement pressure during the pouring process. Secondly, it helps the forming bottom plate 3 to quickly reset after the pouring is completed, facilitating the disassembly of the mold and the next use, and improving the work efficiency. Moreover, it can balance the pressure received by the forming bottom plate 3, making its sliding action smoother, thus ensuring the stability of the internal structure of the mold and the forming quality of the precast components.

[0057] In some examples, the side wall of the second side plate 2 has a clamping portion 201. A second pushing member 12 is further included. One end of the second pushing member 12 is horizontally slidably arranged on the first pushing member 4 along the transverse direction, and the other end is in sliding contact with the side wall of the second side plate 2. The second pushing member 12 has a clamped portion 1201. After the second pushing member 12 slides horizontally, the clamping portion 201 is in sliding contact with the clamped portion 1201, for preventing the first pushing member 4 and the second pushing member 12 from sliding downward.

[0058] In this embodiment, the second pushing member 12 slides on both the first pushing member 4 and the second side plate 2 at the same time. During operation, as the pouring process progresses, when a larger area of support needs to be provided for the second side plate 2 to balance the internal pressure, the second pushing member 12 is pushed to slide on the first pushing member 4 and the second side plate 2. Due to the misaligned sliding of the second pushing member 12 and the first pushing member 4, its contact area increases, and a more uniform and extensive supporting force can be applied to the second side plate 2. When the second pushing member 12 slides to the position where it can provide the maximum supporting force, the clamping portion 201 and the clamped portion 1201 are in mutual contact and clamping. This clamping action can ensure that during the pouring process, even under large internal pressure fluctuations, the second pushing member 12 can remain at the current pressurized position and will not slide off or become loose due to unstable pressure, thus always providing stable and reliable support for the second side plate 2.

[0059] Generally speaking, firstly, the slidable design of the second pressing member 12 can flexibly adjust the supporting area and position according to the actual pressure requirements, achieving more precise and effective support for the second side plate 2, and improving the adaptability and pressure balance ability of the mold. Secondly, the arrangement of the clamping portion 201 and the clamped portion 1201 ensures the firm locking of the second pressing member 12 at the maximum pressing position, effectively preventing slipping and loosening caused by pressure fluctuations, ensuring the stability and reliability of the mold during the pouring process, and thus improving the forming quality of the precast components.

[0060] In some examples, the clamping portion 201 has a rising section 202 and a straight section 203, and the clamped portion 1201 is configured such that during the rising and horizontal sliding process, the clamped portion 1201 slidably abuts against the rising section 202, and after sliding, the clamped portion 1201 is located on the straight section 203.

[0061] In this embodiment, during the working process, when the second pressing member 12 rises and slides horizontally, the clamped portion 1201 first slidably abuts against the rising section 202. As the second pressing member 12 continues to slide, the clamped portion 1201 gradually rises along the rising section 202 until it slides to a position where it contacts the straight section 203. Subsequently, the clamped portion 1201 is clamped with the straight section 203 to achieve locking.

[0062] Generally speaking, firstly, the design of the rising section 202 enables the second pressing member 12 to transition more smoothly during the rising and sliding processes, reducing jamming and resistance, and improving the fluency of operation. Secondly, the clamping structure of the clamped portion 1201 and the straight section 203 is simple and firm, which can effectively prevent accidental loosening and slipping of the second pressing member 12 during work, ensuring the stability and reliability of the mold during the pouring process. Moreover, this segmented clamping structure facilitates the accurate alignment and clamping of the second pressing member 12, improving the efficiency of mold assembly and adjustment.

[0063] In some examples, the side wall of the second side plate 2 further has a first blocking portion 204, and further includes a second sliding block 13. The second sliding block 13 is arranged to lift and slide on the second side plate 2, and after the second sliding block 13 rises and slides, it abuts against the first blocking portion 204; one end of the fourth connecting rod 14 is hinged to the second sliding block 13, and the other end is hinged to the second pressing member 12.

[0064] In this embodiment, during the pouring process, the second sliding block 13 rises, providing a guiding function and at the same time providing a lateral driving force for the other end of the fourth connecting rod 14. After receiving the driving force, the fourth connecting rod 14 drives the second pressing member 12 to slide horizontally, so that the second pressing member 12 supports and presses the second side plate 2, and continuously maintains a locking force on the second pressing member 12 to ensure its stable position and provide effective support. When the concrete member needs to be demolded after solidification, the second sliding block 13 is knocked by manual or equipment to make it slide down. During the sliding down process, the second sliding block 13 cancels the locking force on the second pressing member 12. At the same time, the vibration effect generated by the knocking is transmitted successively through the second pressing member 12, the first pressing member 4, the second side plate 2 and the forming bottom plate 3. This extensive vibration transmission makes the overall mold and the formed concrete member loosen quickly, achieving the effect of rapid demolding.

[0065] Generally speaking, first of all, during the pouring process, the cooperation between the second sliding block 13 and the fourth connecting rod 14 can achieve precise control and stable locking of the second pressing member 12, ensuring the structural stability and reliability of the mold during pouring, thereby improving the forming quality of precast components. Secondly, in the demolding stage, rapid demolding is achieved by knocking the second sliding block 13, greatly improving the production efficiency, reducing the demolding time and the difficulty of manual operation. Moreover, the extensive transmission of vibration between the various components of the mold can evenly loosen the mold and the concrete member, avoiding the demolding difficulties and component damage caused by local adhesion.

[0066] As Figures 5 to 6 shown, in some examples, the second side plate 2 further has air holes 205. The air holes 205 are located at the bottom of the side wall of the second side plate 2 and on the side of the second side plate 2 close to the first side plate 1. The air holes 205 are used to connect the forming space 101 with the outside. It further includes a third sliding block 15. The third sliding block 15 is horizontally slidably arranged on the second side plate 2. The third sliding block 15 has a communication port 1501. The third sliding block 15 is configured such that after sliding, the communication port 1501 communicates with or cancels communication with the air holes 205.

[0067] In this embodiment, at the beginning of pouring, the forming bottom plate 3 will have a small range of downward sliding. During this downward sliding stroke, the third sliding block 15 slides horizontally to make the communication port 1501 communicate with the air holes 205. At this time, the gas at the three-sided angle formed between the first side plate, the second side plate and the forming bottom plate can be discharged. After the exhaust is completed, the third sliding block 15 is slid to cancel the communication between the communication port 1501 and the air holes 205. Since no new gas cavities will be generated at this position during the subsequent cement perfusion process, the quality of the precast component at this key part is ensured.

[0068] Generally speaking, in this solution, air holes 205 are first provided at the three-sided angles where it is difficult to cover the concrete, which can effectively discharge the accumulated gas here, avoid forming gas cavities in the precast components, and significantly improve the quality and structural integrity of the precast components. Secondly, by precisely controlling the sliding timing and position of the third sliding block 15, precise management of the exhaust process is achieved, ensuring that the air holes 205 are only connected when exhaust is needed, reducing the uncertainty during the concrete pouring process. Moreover, this exhaust method effectively solves the quality problems that are prone to occur in similar parts of traditional molds, improving the pouring success rate of the molds and the product qualification rate.

[0069] In some examples, one end of the third sliding block 15 has a clamping portion 1502, and the forming bottom plate 3 also has a first card slot portion 301 and a second card slot portion 302. The first card slot portion 301 and the second card slot portion 302 are vertically adjacent. After the forming bottom plate 3 is configured to lift and slide, the clamping portion 1502 leaves the first card slot portion 301 and enters the second card slot portion 302, or leaves the second card slot portion 302 and enters the first card slot portion 301.

[0070] In this embodiment, the clamping portion 1502 at one end of the third sliding block 15 cooperates with the first card slot portion 301 and the second card slot portion 302 of the forming bottom plate 3 respectively. When the forming bottom plate 3 is in the initial position, the clamping portion 1502 is clamped into the first card slot portion 301. At this time, the position of the third sliding block 15 makes the communication port 1501 and the air hole 205 in a misaligned and non-connected state. During the pouring process, as the concrete is injected, the forming bottom plate 3 slides down to the bottom contact position. At this time, the clamping portion 1502 leaves the first card slot portion 301 and is clamped into the second card slot portion 302, also keeping the communication port 1501 and the air hole 205 misaligned and non-connected.

[0071] Generally speaking, first, through the clamping cooperation of the first card slot portion 301 and the second card slot portion 302 with the clamping portion 1502 at the initial position and the bottom contact position of the forming bottom plate 3, it is ensured that the air hole 205 is in a closed state at these two key positions, effectively guaranteeing the sealing performance of the forming space. Secondly, whether the forming bottom plate 3 is in the initial state without load or the bottom contact state with a large amount of load, the good sealing performance can prevent concrete leakage and ensure the dimensional accuracy and quality of the precast components.

[0072] In some examples, one side of the first card slot portion 301 close to the second card slot portion 302 has a first guiding inclined surface 303, and the upper side of the third sliding block 15 has a second guiding inclined surface 1503. The forming bottom plate 3 is configured such that after descending and sliding, the first guiding inclined surface 303 and the second guiding inclined surface 1503 slide and abut against each other to drive the third sliding block 15 to slide horizontally, so that the air hole 205 is connected to the communication port 1501.

[0073] In this embodiment, when the forming bottom plate 3 descends and slides, the first guiding inclined surface 303 on the side of the first card slot portion 301 close to the second card slot portion 302 slidably abuts against the second guiding inclined surface 1503 on the upper side of the third sliding block 15. As the forming bottom plate 3 continues to descend, the first guiding inclined surface 303 slides along the second guiding inclined surface 1503, generating a component force in the horizontal direction, thereby driving the third sliding block 15 to slide horizontally. When the third sliding block 15 slides horizontally to a certain position, the air hole 205 communicates with the communication port 1501, realizing specific functional requirements, such as exhaust or other operations.

[0074] In this solution, through the cooperation of the first guiding inclined surface 303 and the second guiding inclined surface 1503, the vertical movement of the forming bottom plate 3 is transmitted into the horizontal movement of the third sliding block 15, and the communication between the air hole 205 and the communication port 1501 can be automatically realized at a specific stage when the forming bottom plate 3 descends, so as to realize the rapid discharge of the gas cavity at the trilateral angle formed among the first side plate, the second side plate and the forming bottom plate during this process.

[0075] In some examples, a second elastic member 16 is further included. One end of the second elastic member 16 acts on the second side plate 2, and the other end acts on the third sliding block 15, providing a force for the third sliding block 15 to slide towards the first card slot portion 301 or the second card slot portion 302.

[0076] In this embodiment, when the forming bottom plate 3 rises and resets under the action of the first elastic member 11 or slides down under the gravity of the cement, the elastic force of the second elastic member 16 will pull the third sliding block 15 to slide towards the corresponding card slot portion to realize the misalignment closing of the air hole 205 and the communication port 1501.

Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and they should all be covered within the scope of the claims of the present disclosure.
