Description

Technical Field

[0001] This utility model relates to the field of precast component maintenance technology, specifically a precast component maintenance device. Background Technology

[0002] Precast concrete components (such as precast slabs, precast blocks, and small precast columns) are commonly used basic components in building construction. After they are formed, they need to undergo a certain period of moisturizing and curing operations. By continuously maintaining a moist environment on the surface of the component, the rate of evaporation of water inside the concrete is slowed down, ensuring that the cement hydration reaction is fully carried out. This avoids quality defects such as surface cracking and insufficient internal strength caused by excessive water loss, thus ensuring the mechanical properties and service life of the component.

[0003] In small and medium-sized precast component manufacturers, due to limitations in production scale, site space, and equipment procurement costs, it is difficult to equip them with large-scale automated curing lines. Therefore, a simple curing method of manually watering with a rubber hose is commonly used. The specific operation process is as follows: one end of the rubber hose is connected to a water source or water tank. The worker holds the water outlet of the rubber hose and moves the hose according to the stacking position of the precast components to spray water onto the surface of the components. In order to avoid direct impact of concentrated water flow on the surface of the components and cause damage to the concrete surface, and at the same time to expand the water flow coverage to improve the uniformity of watering, the worker needs to press the wall of the water outlet of the rubber hose with his fingers to form a locally compressed gap structure at the end of the rubber hose. When the water flows out from the gap, it changes from the original columnar flow to a dispersed fan-shaped flow or mist flow, thereby achieving gentle and uniform watering of the surface of the precast components.

[0004] However, the above-mentioned treatment method has some shortcomings in actual use. Specifically, in order to maintain a stable dispersed water flow, workers need to apply pressure to the rubber tube wall with their thumb or forefinger for a long time. When moving the water pipe to adjust the watering position, the pressing action must be maintained simultaneously. The rubber tube wall has a certain elastic reaction force. Long-term concentrated force will cause the workers' finger muscles to be continuously tense, which can easily lead to discomfort symptoms such as fingertip soreness and numbness. Therefore, a prefabricated component curing device is proposed to address the above situation. Utility Model Content

[0005] The purpose of this utility model is to provide a prefabricated component curing device. Through the structural design of a fixed collar, opening, fixed rod, pressure plate and positioning component, the worker can squeeze the water pipe by moving the pressure plate downward. The pressure is constant and does not fluctuate, which solves the problem that workers need to apply pressure to squeeze the rubber pipe wall with their thumb or index finger for a long time, which can easily cause discomfort such as fingertip soreness and numbness.

[0006] This utility model is achieved through the following technical solution: This utility model is a prefabricated component curing device, including a water pipe and a fixing plate, wherein the water inlet end of the water pipe is connected to a water source.

[0007] A fixing collar is detachably installed on the outer wall of the water pipe. One end of the fixing collar has an opening that communicates with the inner cavity of the fixing collar.

[0008] Fixed rods are fixed at both ends of the bottom of the fixed plate. The bottom of the two fixed rods is fixed on the fixed collar. A pressure plate is slidably installed on the two fixed rods. When the pressure plate moves downward, it can squeeze the outer wall of the water pipe. Positioning members are fixed at both ends of the bottom of the pressure plate. One end of the positioning member extends into the interior of the fixed rod.

[0009] Furthermore, the fixing collar includes a lower cover ring, and an upper cover ring is installed on the top of the lower cover ring. Both the lower cover ring and the upper cover ring are arc-shaped structures. The assembly of the lower cover ring and the upper cover ring is fixed to the water pipe by a clamp.

[0010] Furthermore, the lower cover ring is longer than the upper cover ring, and rubber pads are provided on the arc-shaped inner walls of both the lower cover ring and the upper cover ring.

[0011] Furthermore, the outer wall of the fixing rod is provided with positioning holes, and the number of positioning holes is several.

[0012] Furthermore, guide holes are provided at both ends of the top of the pressure plate, and the guide holes are clearance-fitted with the fixing rod.

[0013] Furthermore, the positioning component includes a positioning block, one end of which is fixed with a sliding cylinder. A stepped hole is formed through the positioning block, and a through hole with the same center as the stepped hole is formed on the sliding cylinder. The stepped hole and the through hole are connected.

[0014] A stepped rod is slidably fitted inside the stepped hole. The thicker end of the stepped rod passes through the through hole and extends into the positioning hole. A spring is sleeved on the outer wall of the thinner end of the stepped rod. One end of the spring abuts against the thicker end of the stepped rod, and the other end is fixed to one side of the inner wall of the stepped hole. A handle is fixed after the thinner end of the stepped rod passes through the thinner end of the stepped hole.

[0015] This utility model has the following beneficial effects: This utility model, through its structural design of a fixed collar, opening, fixed rod, pressure plate, and positioning component, allows workers to squeeze the water pipe by moving the pressure plate downwards. The pressure is constant and does not fluctuate, eliminating the need for workers to apply pressure with their fingers to maintain water flow dispersion. They only need to hold the fixed collar to adjust the watering position, avoiding discomfort such as soreness and numbness caused by prolonged tension in the finger muscles, reducing operational interruptions due to fatigue, and meeting the maintenance needs of small and medium-sized manufacturers producing batches of prefabricated components.

[0016] This utility model, through its structural design of a fixed rod, positioning hole, positioning block, sliding cylinder, and stepped rod, allows for adjustment of the pressure plate position and positioning process according to actual needs during use, thereby adjusting the dispersion of the water output. This facilitates the adjustment of the water output by staff based on actual usage requirements.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a precast component curing device, including a water pipe 1 and a fixing plate 4. The water inlet of the water pipe 1 is connected to a water source, and the water outlet is picked up by the worker and directed toward the stacked precast concrete components. Water from the water outlet can spray water to cure the stacked precast concrete components.

[0025] Among them, water pipe 1 is made of aging-resistant rubber pipe with an inner diameter that is compatible with common municipal water source specifications (DN20-DN50). The pipe wall thickness is 3-5mm to ensure that it has a certain degree of elasticity (can be squeezed and deformed) and is not easy to break. The inlet end is equipped with a quick connector, which can be quickly connected to the water source (municipal water pipe, water tank outlet pipe).

[0026] A retaining ring 2 is detachably installed on the outer wall of the water pipe 1. One end of the retaining ring 2 has an opening 3, which communicates with the inner cavity of the retaining ring 2.

[0027] Fixed rods 5 are fixed at both ends of the bottom of the fixed plate 4. The bottom of the two fixed rods 5 is fixed on the fixed collar 2. A pressure plate 6 is slidably installed on the two fixed rods 5. When the pressure plate 6 moves downward, it can squeeze the outer wall of the water pipe 1. Positioning parts 7 are fixed at both ends of the bottom of the pressure plate 6. One end of the positioning part 7 extends into the interior of the fixed rod 5.

[0028] In this embodiment, the fixing collar 2 includes a lower cover ring 20, and an upper cover ring 21 is installed on the top of the lower cover ring 20. Both the lower cover ring 20 and the upper cover ring 21 are arc-shaped structures. The assembly of the lower cover ring 20 and the upper cover ring 21 is fixed to the water pipe 1 by a clamp 22. The length of the lower cover ring 20 is greater than that of the upper cover ring 21. Rubber pads are provided on the arc-shaped inner walls of both the lower cover ring 20 and the upper cover ring 21.

[0029] Among them, the lower cover ring 20 is longer, which can provide stable support for the water pipe 1, prevent the water pipe 1 from shifting downward when the pressure plate 6 is squeezed, and ensure accurate pressing position. The rubber pad can increase the friction between the collar and the water pipe, prevent the collar from sliding, and at the same time buffer the rigid contact to prevent the outer wall of the water pipe 1 from being squeezed and damaged.

[0030] Among them, the clamp 22 is made of stainless steel (rust-proof), with a width of 15-20mm, and is equipped with a wing bolt, which can be tightened manually without tools. The lower cover ring 20 and the upper cover ring 21 are both made of ABS engineering plastic.

[0031] In this embodiment, the outer wall of the fixing rod 5 is provided with positioning holes 50, and the number of positioning holes 50 is several.

[0032] Among them, the multi-position positioning hole 50 provides different pressing depth options for the pressure plate 6. Workers can control the degree of water pipe compression by inserting the positioning piece 7 into the positioning hole 50 at different heights. The lower the positioning hole 50, the larger the compression gap of the water pipe 1 and the wider the water flow.

[0033] In this embodiment, guide holes 60 are provided at both ends of the top of the pressure plate 6, and the guide holes 60 are clearance-fitted with the fixing rod 5.

[0034] The inner wall of the guide hole 60 is provided with a polytetrafluoroethylene wear-resistant coating. The guide hole 60 provides vertical guidance for the pressure plate 6, preventing the pressure plate 6 from shifting or tilting, ensuring that the water pipe 1 is subjected to uniform force, preventing water flow deviation, reducing sliding friction, reducing component wear, extending service life, and making the pressure plate slide more smoothly, improving the ease of operation.

[0035] In this embodiment, the positioning member 7 includes a positioning block 70, one end of which is fixed with a slide cylinder 71. A stepped hole 700 is provided through the positioning block 70, and a through hole 710 with the same center as the stepped hole 700 is provided on the slide cylinder 71. The stepped hole 700 and the through hole 710 are connected.

[0036] A stepped rod 72 is slidably fitted inside the stepped hole 700. The thicker end of the stepped rod 72 passes through the through hole 710 and extends into the positioning hole 50. A spring 73 is sleeved on the outer wall of the thinner end of the stepped rod 72. One end of the spring 73 abuts against the thicker end of the stepped rod 72, and the other end is fixed to one side of the inner wall of the stepped hole 700. A handle 74 is fixed after the thinner end of the stepped rod 72 passes through the thinner end of the stepped hole 700.

[0037] When using the above device: According to the maintenance scenario of the precast components, the degree of water pipe compression is controlled by adjusting the height of the pressure plate 6. Pull the handle 74 to slide the pressure plate 6 downward until the pressure plate 6 is in contact with the outer wall of the water pipe 1. Continue to move the water pipe 1 downward until the step rod 72 is aligned with the positioning hole 50 of the fixing rod 5. At this time, the water pipe is compressed to form a "narrow and long gap of about 2 to 3 mm". Release the handle 74, the spring 73 returns to its natural state, push the step rod 72, slide in the opposite direction, and the thick rod end re-extends into the corresponding positioning hole 50 to achieve stable fixation of the pressure plate 6.

[0038] Connect the quick connector at the inlet end of water pipe 1 to the water source (such as municipal water pipe or water tank outlet pipe), open the water source valve, and the water flows along water pipe 1 to the outlet end. Because water pipe 1 is squeezed by the pressure plate to form a "fixed gap", when the water flows out from the gap, it changes from the original columnar flow to a uniform fan-shaped flow and sprays onto the surface of the precast component for curing.

[0039] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
