Description

Technical Field

[0001] The patent of this invention relates to the technical field of ultra-high performance concrete, specifically, to a curing film covering construction method suitable for curing ultra-high performance concrete layers. Background Art

[0002] In the curing process of ultra-high performance concrete (UHPC), curing membranes are widely used as an effective curing method to cover the surface of concrete structures to reduce water evaporation and maintain appropriate temperature and humidity, thereby ensuring that the hydration reaction of the concrete proceeds fully and ultimately achieves the desired strength and durability.

[0003] Therefore, the degree of fit between the curing membrane and the ultra-high performance concrete layer is one of the important factors that determine whether the construction requirements can be met.

[0004] In the existing technology, workers usually manually unfold and cover the curing film on the concrete surface. Due to the limitations of manual operation, it is difficult to ensure that the curing film is tightly adhered to the concrete layer. For example, on large-area concrete structures, manual laying is prone to wrinkles, bubbles, and uneven coverage. This not only damages the integrity of the curing film, but also causes accelerated water evaporation in local areas and drastic temperature changes, which in turn affects the curing quality of the concrete and increases the risk of defects such as cracks.

[0005] Furthermore, existing mechanical film-laying equipment applies the curing film by simply rolling it into contact with the concrete surface. This can achieve a certain degree of adhesion for relatively flat concrete surfaces, but for ultra-high-performance concrete layers with subtle undulations or uneven surfaces, simple rolling makes it difficult to fully conform the curing film to the complex contours of the concrete. This is particularly problematic around the edges and corners of concrete structures, as well as in areas with obstacles such as rebar and formwork. Summary of the Invention

[0006] The purpose of the present invention is to provide a curing film covering construction method suitable for curing ultra-high performance concrete layers, aiming to solve the problem in the prior art that the curing film and the ultra-high performance concrete layer are not tightly attached.

[0017] Furthermore, in the construction step 1), a plurality of connecting rods are provided between the two transverse guide rails, and the plurality of connecting rods are arranged at intervals along the length direction of the transverse guide rails.

[0018] Furthermore, in the construction step 1), an adjusting head that can be rotated to adjust the length is provided in the middle of the connecting rod. By rotating the adjusting head, the length of the connecting rod is changed, so that the interval between the two transverse guide rails is changed.

[0019] Furthermore, in the construction step 1), a front water spray head and a rear water spray head are provided on the frame, and along the moving direction of the frame on the transverse guide rail, the front water spray head is located in front of the rolling axis, and the rear water spray head is located behind the pressure axis;

[0020] In the construction step 3), when the frame moves along the transverse guide rail, the front water spray head sprays water mist on the ultra-high performance concrete layer, and then the pressure shaft covers the curing film on the ultra-high performance concrete layer.

[0022] Furthermore, in the construction step 1), there is a transverse gap between the two transverse guide rails, and transversely arranged pedal strips are provided on the transverse guide rails.

When the frame moves along the transverse guide rail, the counterweight shaft is squeezed by the elastic layer and its own gravity, vibrating back and forth circumferentially within the annular cavity. This enhances the pressure and uniformity of the elastic layer on the curing membrane, ensuring seamless fit between the curing membrane and the concrete layer, improving the curing effect, and reducing the risk of defects such as cracks in the concrete due to poor fit.

[0047] Reference Figure 1-9 The figure shows a preferred embodiment of the present invention.

[0048] The curing film covering construction method suitable for curing ultra-high performance concrete layers includes the following construction steps:

[0049] 1) Pour ultra-high performance concrete on the construction site to form an ultra-high performance concrete layer 100. Longitudinal guide rails 101 are formed on both sides of the ultra-high performance concrete. Two spaced transverse guide rails 102 are provided between the two longitudinal guide rails 101. A vehicle frame 200 is provided between the two transverse guide rails 102.

[0050] The bottom of the frame 200 is provided with a rolling shaft and a telescopic shaft 300. The rolling shaft is provided with a curing film 302 roll 301. The curing film 302 roll 301 is formed by the curing film 302 being rolled up. The telescopic shaft 300 is connected to the pressing shaft 201 in a rolling arrangement.

[0051] An elastic layer 202 surrounds the outer periphery of the pressure shaft 201. The elastic layer 202 defines an annular cavity 203. The annular cavity 203 surrounds the pressure shaft 201. A movably arranged counterweight shaft 205 is provided at the bottom of the annular cavity 203. The counterweight shaft 205 is movably clamped in the annular cavity 203.

[0052] 2) The two transverse guide rails 102 move synchronously along the longitudinal guide rail 101 to a set step length, and the frame 200 moves synchronously with the two transverse guide rails 102;

[0053] 3) The end of the curing film 302 on the curing film roll 301 abuts against the ultra-high performance concrete layer 100, and the telescopic shaft 300 moves downward until the elastic layer 202 presses against the curing film 302; the frame 200 moves along the transverse guide rail 102, and the curing film 302 covers the ultra-high performance concrete layer 100. The elastic layer 202 presses against the curing film 302, so that the curing film 302 adheres to the ultra-high performance concrete layer 100, forming a covering layer;

[0054] The elastic layer 202 presses against the curing film 302 , and when the vehicle frame 200 moves along the transverse guide rail 102 , the counterweight shaft 205 is squeezed by the elastic layer 202 and, under the action of its own gravity, reciprocates along the circumference of the annular cavity 203 ;

[0055] 4) When the vehicle frame 200 moves to the end of the ultra-high performance concrete layer 100, the curing film 302 is cut to separate the covering layer from the curing film 302 roll 301;

[0056] 5) Repeat construction steps 2) to 4) until the entire ultra-high performance concrete layer 100 is covered with a film layer, and adjacent film layers are overlapped.

[0057] The above-mentioned method for coating the curing film 302 for curing the ultra-high performance concrete layer 100 has the following technical advantages:

[0058] 1) During the construction process, the elastic layer 202 presses tightly against the curing membrane 302, so that the curing membrane 302 can fit tightly against the surface of the ultra-high performance concrete layer 100. When the vehicle frame 200 moves along the transverse guide rail 102, the counterweight shaft 205 is squeezed by the elastic layer 202 and its own gravity, and vibrates back and forth circumferentially in the annular cavity 203. This enhances the pressure and uniformity of the elastic layer 202 on the curing membrane 302, ensures seamless fitting between the curing membrane 302 and the concrete layer, improves the curing effect, and reduces the risk of defects such as cracks in the concrete due to poor fitting.

[0059] 2) By synchronously moving the transverse guide rail 102 along the longitudinal guide rail 101 to set the step length, the frame 200 is driven to move synchronously, thereby achieving continuous and uniform laying of the curing film 302. The construction steps are repeated until the entire ultra-high performance concrete layer 100 is covered with the covering layer, and the adjacent covering layers are arranged in an overlapping manner, avoiding problems such as missing paving and uneven coverage that may occur in manual paving, thereby improving construction efficiency and helping to speed up the construction progress.

[0060] 3) By adjusting the position and spacing of the longitudinal guide rail 101 and the transverse guide rail 102, as well as the moving step length of the frame 200, it can flexibly adapt to various construction sites and concrete structures without the need for pre-treatment of the concrete surface, thereby reducing construction costs and difficulty and improving construction flexibility and adaptability.

[0061] In this embodiment, in construction step 1), a longitudinally arranged connecting rod 103 is connected between the two transverse guide rails 102 , and the connecting rod 103 connects the two transverse guide rails 102 into one body, so that the two transverse guide rails 102 move synchronously along the longitudinal guide rail 101 .

[0062] In this way, it is ensured that the two transverse guide rails 102 always remain synchronized during the movement, thereby making the movement of the frame 200 more stable, providing a stable moving foundation for the subsequent uniform laying of the curing membrane 302, and improving the overall stability of the laying of the curing membrane 302, which is beneficial to the adhesion of the curing membrane 302 to the ultra-high performance concrete layer 100.

[0063] In this embodiment, in construction step 1), a plurality of connecting rods 103 are provided between the two transverse guide rails 102 , and the plurality of connecting rods 103 are arranged at intervals along the length direction of the transverse guide rails 102 .

[0064] In this way, the connection strength and stability between the two transverse guide rails 102 can be further enhanced, making the transverse guide rails 102 more stable when moving, reducing the uneven laying of the curing film 302 caused by structural shaking, and thereby improving the tightness of the curing film 302 on the ultra-high performance concrete layer 100, thereby better ensuring the quality of the fit between the curing film 302 and the concrete layer.

[0065] In this embodiment, in construction step 1), an adjusting head 104 that can be rotated to adjust the length is provided in the middle of the connecting rod 103. By rotating the adjusting head 104, the length of the connecting rod 103 is changed to change the interval between the two transverse guide rails 102.

[0066] Through the adjustable length connecting rod 103, it can be flexibly adjusted according to different construction sites and ultra-high performance concrete layers 100 of different sizes, so that the equipment can adapt to a variety of construction scenarios, enhancing the flexibility and adaptability of construction. At the same time, this adjustment function can also ensure that the spacing between the transverse guide rails 102 is accurate and appropriate, creating conditions for the smooth movement of the frame 200 and the accurate laying of the curing film 302, thereby ensuring that the curing film 302 can fit closely to the concrete layer and improve the curing effect.

[0067] In this embodiment, in construction step 1), a front water spray head 208 and a rear water spray head 209 are provided on the vehicle frame 200. Along the moving direction of the vehicle frame 200 on the transverse guide rail 102, the front water spray head 208 is located in front of the rolling axis, and the rear water spray head 209 is located behind the pressure axis 201;

[0068] In construction step 3), as the vehicle frame 200 moves along the transverse guide rail 102, the front sprinkler head 208 sprays water mist onto the ultra-high performance concrete layer 100, and then the pressure shaft 201 covers the curing film 302 onto the ultra-high performance concrete layer 100. After the curing film 302 covers the ultra-high performance concrete layer 100, the rear sprinkler head 209 sprays water mist onto the curing film 302.

[0069] The front water spray head 208 provided on the vehicle frame 200 can first moisten the concrete surface, which helps to improve the adhesion between the curing film 302 and the concrete. At the same time, the water mist sprayed by the rear water spray head 209 can make the curing film 302 better fit the concrete surface, further enhancing the tightness of the fit between the curing film 302 and the concrete layer.

[0070] In this embodiment, in construction step 1), a water-absorbing layer is formed on the curing membrane 302; in construction step 3), after the curing membrane 302 is covered on the ultra-high performance concrete layer 100, the water-absorbing layer is arranged upward, and the water mist sprayed from the rear sprinkler head 209 is sprayed on the water-absorbing layer and absorbed by the water-absorbing layer.

[0071] The presence of the water-absorbing layer can absorb the water mist sprayed by the rear water spray head 209, so that a certain humidity is maintained between the curing film 302 and the concrete layer, which is conducive to the curing film 302 to better fit the concrete surface and improve the adhesion between the curing film 302 and the concrete layer. In addition, after the water-absorbing layer absorbs the water mist, it can increase the friction between the curing film 302 and the concrete layer, making the curing film 302 more stable on the concrete layer and avoiding the curing film 302 from sliding on the concrete surface due to water mist.

[0072] In this embodiment, in construction step 1), there is a transverse gap 105 between the two transverse guide rails 102, and a transversely arranged pedal strip 106 is provided on the transverse guide rail 102. The pedal strip 106 extends away from the transverse gap 105 and is arranged lower than the transverse guide rail 102.

[0073] By setting the pedal bar 106, a convenient working platform is provided for construction workers, so that construction workers can stand stably on the transverse guide rail 102 to operate, avoiding construction workers from interfering with equipment or curing film 302 during operation, and indirectly ensuring the stability of laying of curing film 302.

[0074] In this embodiment, in construction step 1), the bottom of the telescopic shaft 300 is connected to a bottom frame 303, and both ends of the bottom frame 303 are respectively provided with a transverse hole. The inner side wall of the transverse hole is covered with an elastic ring 304. A transverse head 305 is passed through the transverse hole. The elastic ring 304 is wrapped around the outer circumference of the transverse head 305, and the transverse head 305 is movably inserted between the two transverse heads 305 arranged on the pressing shaft 201.

[0075] In construction step 3), while the elastic layer 202 of the pressing shaft 201 presses the curing membrane 302 to adhere to the ultra-high performance concrete layer 100 , the pressing shaft 201 elastically vibrates along the radial direction of the elastic ring 304 .

[0076] When the pressing shaft 201 has a certain elastic vibration when pressing the curing membrane 302 , it can better adapt to the surface unevenness of the ultra-high performance concrete layer 100 , so that the curing membrane 302 fits tightly on the concrete layer under the action of the elastic layer 202 .

[0077] In this embodiment, in construction step 1), annular grooves 204 are respectively provided at both ends of the annular cavity 203, and the annular grooves 204 are arranged around the circumference of the annular cavity 203, and the end of the counterweight shaft 205 is movably placed in the annular groove 204; in construction step 3), during the process of the counterweight shaft 205 vibrating back and forth along the circumference of the annular cavity 203, the end of the counterweight shaft 205 moves back and forth along the annular groove 204.

[0078] In this way, the movement trajectory of the counterweight shaft 205 is made more stable, and the shaking of the counterweight shaft 205 during the vibration process is reduced, so that the elastic layer 202 can press the curing film 302 more evenly.

[0079] In this embodiment, in construction step 1), a plurality of axial grooves are provided on the outer circumference of the counterweight shaft 205. The plurality of axial grooves are arranged around the circumference of the counterweight shaft 205 at intervals. The axial grooves are filled with elastic strips 206. A deformation gap 207 is provided between the inner end of the elastic strip 206 and the bottom of the axial groove. The outer end of the elastic strip 206 extends to the outside of the axial groove.

[0080] In construction step 3), during the reciprocating vibration of the counterweight shaft 205 along the circumferential direction of the annular cavity 203, the elastic strip 206 is squeezed and deformed toward the axial groove.

[0081] By providing the elastic strip 206, an outward-resetting elastic force can be generated, thereby expanding the annular cavity 203, preventing the counterweight shaft 205 from being stuck in the annular cavity 203, and ensuring that the counterweight shaft 205 always remains active during the vibration process, so that the elastic layer 202 can continuously and effectively press against the curing membrane 302, making it fit tightly on the ultra-high performance concrete layer 100.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
