Description

Technical Field

[0001] The present application relates to the technical field of concrete curing, and in particular to a reusable concrete curing formwork. Background Art

[0002] As a commonly used building material, the strength and stability of concrete have an important impact on the safety and durability of building structures. In the curing process of concrete, maintaining appropriate humidity is a crucial step.

[0003] In the related art, a Chinese patent with application number 201922182068.7 proposes a concrete curing device, including a first template, a second template and a curing layer, wherein the first template is provided with a water seepage window and a draw plate, the draw plate covers the water seepage window and is movably connected to the water seepage window; the second template is arranged in parallel with the first template and connected to the first template through a connecting member, wherein the curing layer is filled between the first template and the second template. The second template can move toward or away from the first template under the action of the connecting member. The curing layer is a compressible layer and can store more water. Under the action of external force, the water in the curing layer can be squeezed out. When the second template moves toward the direction close to the first template under the action of the connecting member, the water in the curing layer can be squeezed out and flow into the concrete surface through the water seepage window.

[0004] With respect to the above-mentioned related art, when the second template moves toward the first template under the action of the connecting member, the curing layer is squeezed, so that the water in the curing layer is squeezed out. Since the first template and the second template are arranged in parallel, part of the squeezed water flows into the concrete surface through the seepage window, while the other part of the water flows out from between the first template and the second template, so that the water utilization rate in the curing layer is low.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The present application embodiment discloses a reusable concrete curing formwork. Figure 1 , Figure 2 and Figure 3 A reusable concrete curing formwork comprises a curing plate 1, a felt layer 4 and a regulating component; a cavity 2 for holding water is provided inside the curing plate 1, a water injection port 20 connected to the cavity 2 is provided on the curing plate 1, and a movable cover at the water injection port 20 is provided with a sealing plug 21. After the sealing plug 21 is opened, an appropriate amount of water can be injected into the cavity 2 through the water injection port 20. A water seepage window 3 connected to the cavity 2 is provided on the side wall of one side of the curing plate 1. When curing concrete, the side wall of the curing plate 1 with the water seepage window 3 is attached to the concrete, so that the water in the cavity 2 can flow out through the water seepage window 3 and the concrete can be cured. In order to improve the curing efficiency of the curing plate 1 on the concrete, a plurality of water seepage windows 3 are provided, and the plurality of water seepage windows 3 are arranged parallel to each other and spaced apart, so that the water in the cavity 2 can quickly flow to the concrete through the plurality of water seepage windows 3. In order to avoid the problem that the water in the cavity 2 is lost too quickly from the water seepage window 3, thereby wasting water resources and the concrete is difficult to harden and form due to excessive humidity, a felt layer 4 is arranged in the cavity 2, and the felt layer 4 is stably bonded to the inner wall of the cavity 2 by waterproof glue, so that the felt layer 4 covers the water seepage window 3; and the felt layer 4 can absorb the water in the cavity 2, so that the felt layer 4 becomes moist. When the side wall of the curing board 1 with the water seepage window 3 is attached to the concrete, the water in the cavity 2 will not be lost in large quantities, and the moist felt layer 4 can also keep the concrete curing surface in a moist environment, thereby achieving efficient curing of the concrete, avoiding the waste of water resources, and improving the utilization rate of the water in the cavity 2.

[0033] Considering that the humidity required for concrete curing is different in different climates, Figure 1 , Figure 2 and Figure 4 The regulating component is located outside the cavity 2 and is arranged on the side wall of the maintenance plate 1 on the side where the water seepage window 3 is provided. The regulating component includes a grille plate 7 slidably connected to the side wall of the maintenance plate 1 on the side where the water seepage window 3 is provided and a locking member for locking the grille plate 7 on the side wall of the maintenance plate 1; the sliding direction of the grille plate 7 is consistent with the spacing distribution direction of the multiple water seepage windows 3. The grille plate 7 includes a plurality of bars 6 arranged parallel to each other, two connecting plates 23 stably connected to the two ends of the bars 6, and a crossbeam 5 located at the top of the bars 6 and fixedly connected to the two connecting plates 23 at both ends. The plurality of bars 6 are spaced apart along the sliding direction of the grille plate 7, and the bars 6 are arranged parallel to the water seepage windows 3. At the same time, the plurality of bars 6 correspond to the plurality of water seepage windows 3 one by one, and the gap between two adjacent bars 6 is the same as the size of the water seepage windows 3, and the size of the bars 6 is also the same as the size of the water seepage windows 3, so that as the grille plate 7 slides on the maintenance plate 1, the openings of the plurality of water seepage windows 3 are the same, and the plurality of bars 6 can also cover the plurality of water seepage windows 3 at the same time. The locking member is located between the grille plate 7 and the maintenance plate 1, and can lock the grille plate 7 to the side wall of the maintenance plate 1. According to the humidity required for concrete curing, the grid plate 7 is driven to slide on the curing plate 1, and the opening of the seepage window 3 is adjusted by adjusting the coverage of the grid bars 6 on the seepage window 3. Finally, the grid plate 7 is stably locked on the curing plate 1 using a locking member to ensure that the opening size of the seepage window 3 is stable, thereby achieving efficient curing of the concrete. When the concrete does not need to be cured, the grid plate 7 can be driven to slide on the curing plate 1 so that multiple grid bars 6 cover and shield multiple seepage windows 3 respectively. At this time, multiple seepage windows 3 are all closed, which reduces the volatilization loss of water in the cavity 2 to a certain extent, avoids the waste of water resources, and improves the utilization rate of water in the cavity 2.

[0034] To ensure that the grid plate 7 can stably slide on the maintenance plate 1, so as to conveniently adjust the opening of the water seepage window 3, refer to Figure 2 , Figure 3 and Figure 4 The side wall of the maintenance plate 1 on which the water seepage window 3 is provided has two T-shaped chute 8, which are respectively located on both sides of the water seepage window 3, and the length direction of the chute 8 is consistent with the sliding direction of the grille plate 7. T-shaped sliders 9 slidably connected to the chute 8 are fixedly installed on the two connecting plates 23 of the grille plate 7. The grille plate 7 is slidably attached to the side wall of the maintenance plate 1 through the sliders 9, so that the grille plate 7 can be stably attached and slidably set on the side wall of the maintenance plate 1. By moving the grille plate 7 on the maintenance plate 1, the opening and closing of the water seepage window 3 and the adjustment of the opening degree are realized.

[0035] After the opening of the water seepage window 3 is adjusted, in order to quickly lock the grille plate 7 on the maintenance plate 1 to ensure that the opening of the water seepage window 3 is stable, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The locking member includes an anti-skid pad 25 fixed on the inner wall of the slide groove 8 and a locking screw 10 threaded through the grille plate 7. The anti-skid pad 25 can be made of rubber material or damping material, and is located on the inner wall of one side of the notch of the slide groove 8. Two locking screws 10 are provided, and the two locking screws 10 are respectively threaded through the two connecting plates 23 of the grille plate 7, and by rotating the locking screw 10, the end of the locking screw 10 extends into the slide groove 8 and abuts against the bottom wall of the slide groove 8, thereby pushing the slider 9 away from the surface of the bottom wall of the slide groove 8 and abutting against the anti-skid pad 25. By increasing the friction between the slider 9 and the anti-skid pad 25, the grille plate 7 is quickly locked and fixed on the maintenance plate 1. Taking into account that when curing concrete, the surface of the grille plate 7 away from the curing plate 1 needs to be in contact with the concrete, in order to prevent the locking screw 10 from protruding from the grille plate 7 and causing pressure loss on the concrete curing surface, a countersunk threaded hole 24 is opened on the surface of the grille plate 7 away from the curing plate 1, so that when one end of the locking screw 10 abuts against the anti-slip pad 25, the other end is located in the countersunk threaded hole 24.

[0036] In order to enable the grating plate 7 to slide on the protective plate 1 quickly, Figure 1 and Figure 4 A handle 11 is provided on the crossbeam 5. When the opening of the water seepage window 3 needs to be adjusted, the handle 11 can be used to quickly drive the grille plate 7 to slide on the maintenance plate 1, thereby quickly completing the opening adjustment of the water seepage window 3.

[0037] When the length of the concrete is much longer than the length of a single curing board 1, multiple curing boards 1 are needed to cure the concrete. In order to ensure that multiple curing boards 1 can be stably and spaced on the concrete, refer to Figure 1 and Figure 2 A plug connector 12 is provided at one end of the maintenance plate 1, and a plug groove 13 which is plugged and adapted with the plug connector 12 is provided at the other end. Plug pins 14 are plugged and pulled out on the groove walls at both ends of the plug groove 13, and pin holes 15 for inserting the plug pins 14 are provided on both ends of the plug connector 12. When the plug connector 12 is inserted into the plug groove 13, the plug pin 14 is passed through the groove wall of the plug groove 13 and inserted into the corresponding pin hole 15, so that the plug connector 12 can be stably locked in the plug groove 13, so that two adjacent maintenance plates 1 can be quickly assembled and connected, and multiple maintenance plates 1 assembled and connected together can be stably and spaced on the concrete.

[0038] During the process of vertical placement of the curing plate 1 and curing the vertical concrete side wall, the water level in the cavity 2 gradually decreases. At this time, the humidity of the upper part of the felt layer 4 is low, and the humidity of the lower part of the felt layer 4 is high, resulting in a large humidity difference between the upper and lower parts of the felt layer 4. This will affect the curing effect of the vertical concrete side wall. For this reason, refer to Figure 3 , Figure 6 and Figure 7 A push plate 16 is slidably arranged in the cavity 2. The push plate 16 is slidably arranged in the direction of approaching / moving away from the water seepage window 3. A push rod 17 is fixed on the side of the push plate 16 away from the water seepage window 3. The end of the push rod 17 away from the push plate 16 is movably penetrated through the inner wall of the cavity 2 and extends to the outside of the maintenance plate 1. The push plate 16 can be pushed to slide back and forth in the cavity 2 by the push rod 17. Rubber strips 18 are installed on the surrounding walls of the push plate 16. The rubber strips 18 elastically abut against the inner wall of the cavity 2, so that the push plate 16, the rubber strips 18 and the push rod 17 are combined together to form a piston assembly in the cavity 2. The water in the cavity 2 is always located on the side of the push plate 16 close to the water seepage window 3. A through groove is provided on the top of the curing plate 1, and a transparent acrylic plate is provided on the curing plate 1 at the sealing cover of the through groove, so that a visual area 22 for observing the water level in the cavity 2 is formed on the top of the curing plate 1; the water level in the cavity 2 is observed through the visual area 22, and when the water level in the cavity 2 is lowered, the push plate 16 is pushed toward the seepage window 3 by the push rod 17 to reduce the space between the push plate 16 and the seepage window 3, ensuring that the upper part of the felt layer 4 is also immersed in water, which can reduce the humidity difference between the upper and lower parts of the felt layer to a certain extent, thereby ensuring the curing effect of the vertically placed curing plate 1 on the vertical side wall of the concrete.

[0039] During the curing process of the concrete by the curing plate 1, the dust on the surface of the concrete will also penetrate the felt layer 4 with the water and enter the cavity 2. In order to ensure that the push plate 16 can slide stably in the cavity 2, refer to Figure 3 , Figure 6 and Figure 7 Scrapers 19 are fixed on both sides of the push plate 16 on the rubber strip 18. The scrapers 19 are arranged along the edge of the push plate 16 and are inclined against the inner walls around the cavity 2. As the push plate 16 slides back and forth in the cavity 2, the scrapers 19 can scrape off the dust attached to the inner walls around the cavity 2, which not only ensures that the push plate 16 can slide smoothly in the cavity 2, but also ensures that the rubber strip 18 is always in close contact with the inner wall of the cavity 2, preventing the water on the side of the push plate 16 close to the water seepage window 3 from flowing into the side of the push plate 16 away from the water seepage window 3. The scraped dust can be dumped out regularly through the water injection port 20 to ensure the cleanliness of the inner wall of the cavity 2.

[0040] The implementation principle of a reusable concrete curing formwork in the embodiment of the present application is as follows: first, select the appropriate number of curing plates 1 according to the size of the concrete to be cured, and connect multiple curing plates 1 in sequence through the plug slots 13, the plug connectors 12 and the plugs 14. Then, pull the push plate 16 away from the water seepage window 3 through the push rod 17, then open the sealing plug 21, inject a proper amount of water into the cavity 2 through the water injection port 20, and then use the sealing plug 21 to seal the water injection port 20. Finally, push the push plate 16 toward the water seepage window 3 through the push rod 17, observe the water level in the cavity 2 through the visual area 22, and ensure that the upper part of the felt layer 4 is also immersed in water.

[0041] Then, the opening of the water seepage window 3 is adjusted according to the humidity required for concrete curing. At this time, it is only necessary to rotate the locking screw 10 first so that the locking screw 10 does not abut against the bottom wall of the chute 8, and then pull the grille plate 7 through the handle 11 to adjust the opening of the water seepage window 3. Finally, the locking screw 10 is rotated so that the end of the locking screw 10 extends into the chute 8 and abuts against the bottom wall of the chute, thereby pushing the sliding block 9 away from the surface of the bottom wall of the chute 8 and abutting against the anti-skid pad 25. By increasing the friction between the sliding block 9 and the anti-skid pad 25, the grille plate 7 is quickly locked and fixed on the curing plate 1.

[0042] After the adjustment of the curing plate 1 and the grid plate 7 is completed, multiple curing plates 1 are placed on the concrete to be cured in sequence, so that the grid plate 7 is in contact with the curing surface of the concrete. At this time, the felt layer 4 can absorb the water in the cavity 2, so that the felt layer 4 becomes moist. The moist felt layer 4 covers the concrete, thereby achieving the curing of the concrete. In the process of curing the concrete, the water level in the cavity 2 can be observed through the visual area 22. When the water level in the cavity 2 is lowered, the push plate 16 is pushed toward the seepage window 3 by the push rod 17 to reduce the space between the push plate 16 and the seepage window 3, ensuring that the upper part of the felt layer 4 is also soaked in water, which can reduce the humidity difference between the upper and lower parts of the felt layer to a certain extent, and ensure the curing effect of the curing plate 1 on the concrete.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
