Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge construction technology, and in particular to a formwork system with a spraying device. Background Technology
[0002] In bridge pier construction, the hydration reaction of concrete during the early hardening stage is crucial to the structural quality. Rapid water loss in the early stages can easily lead to plastic shrinkage cracks, thus reducing the structure's density and durability. To ensure adequate internal hydration and surface wetting of the concrete, traditionally, water is sprayed from the ground onto the pier using pump trucks or water trucks for curing.
[0003] However, this method has significant shortcomings in the construction of high bridge piers: as the height of the piers increases, the water column is easily affected by external factors such as gravity and wind when it reaches a higher position, resulting in uneven distribution of the sprayed water and incomplete curing coverage. In addition, the spraying angle often needs to be frequently adjusted during on-site spraying, leading to delays in curing time and localized water loss, which may ultimately cause localized cracks and uneven strength in the concrete. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of conventional spray curing methods when the piers are high, such as uneven curing of concrete at high altitudes and the tendency for local water loss due to untimely spraying. This invention provides a formwork system with a spraying device.
[0005] In a first aspect, the present invention provides a template system with a spraying device, comprising a plurality of templates forming a pier casting cavity, and further comprising:
[0006] A circumferential water pipe surrounds the pier casting cavity formed by the template, and the circumferential water pipe is attached to the top of the template;
[0007] Several vertical water pipes are provided, one end of which is connected to the circumferential water pipe, and the other end of which is equipped with an atomizing nozzle.
[0008] The template system with a spraying device provided by this utility model has a circumferential water pipe that surrounds the top of the pier casting cavity formed by the template, which can evenly distribute the water flow to all directions of the pier. This circumferential arrangement avoids the problem of uneven water column distribution due to gravity or wind interference in traditional spraying methods, ensuring the uniformity of spraying in the horizontal direction; the circumferential water pipe can be directly and conveniently hung on the top of the template, avoiding the trouble of installing the circumferential water pipe at high altitude, and improving the convenience of spraying device installation.
[0009] Vertical water pipes extend downwards from the circumferential water pipes, with atomizing nozzles installed at the ends. This structure allows water to be sprayed evenly from top to bottom, covering the entire surface of the poured concrete section of the pier. The atomizing nozzles transform the water flow into a fine mist, significantly increasing the spraying area and uniformity, making it particularly suitable for the high-altitude maintenance needs of tall piers.
[0010] Preferably, it further includes:
[0011] Several brackets are installed on the top of the template, and the circumferential water pipe is attached to the brackets.
[0012] The bracket, as a specialized support structure, effectively supports the upper walkways, fences, ladders, and other structures, while providing reliable attachment points for the circumferential water pipes. The circumferential water pipes are directly attached to the brackets, fully utilizing their stability to ensure the sprinkler system will not shift or detach during construction, thus guaranteeing system reliability and maintenance effectiveness. Furthermore, attaching the circumferential water pipes to the brackets avoids cumbersome high-altitude fixing operations, significantly reducing the difficulty and time required for pipe installation, improving construction efficiency, and alleviating the labor intensity of construction workers.
[0013] Preferably, it further includes:
[0014] A walkway slab is installed on top of the corbel, and the circumferential water pipe is located between the walkway slab and the template.
[0015] With this structural arrangement, the circumferential water pipe is located between the walkway slab and the formwork. That is, the walkway slab does not directly contact the formwork, but rather the walkway slab, corbel, and formwork form an upward-facing concave space. The circumferential water pipe is arranged within this concave space, making full use of this area, avoiding additional construction space occupation, and maximizing the use of the limited construction environment. The structural design of the concave space plays a natural limiting role for the circumferential water pipe, effectively preventing the circumferential water pipe from shifting or shaking during construction, thereby ensuring its positional stability.
[0016] Preferably, the vertical water pipes are spaced apart along the circumferential water pipes.
[0017] With this structural setup, vertical water pipes are evenly arranged at certain intervals along the circumferential water pipes, ensuring that the water flow can cover all areas of the bridge pier surface through the atomizing nozzles. This avoids spray dead zones or water flow concentration in a certain area, thereby achieving all-round uniform curing of the bridge pier surface and reducing plastic shrinkage cracks caused by local water loss.
[0018] Preferably, the spacing between adjacent vertical water pipes is 100±20CM.
[0019] The preferred spacing between adjacent vertical water pipes is 100±20CM, which can effectively reduce plastic shrinkage cracks caused by uneven curing.
[0020] Preferably, the atomizing nozzle is directed toward the cast-in-place bridge pier.
[0021] With this structural setup, the atomizing nozzles are directed towards the poured piers, ensuring that the water mist is sprayed directly onto the concrete surface, maximizing the curing effect, preventing the water mist from dispersing into unrelated areas, reducing water waste, and improving the targeting and efficiency of the spraying.
[0022] Preferably, it also includes a connecting buckle, which is located at one end of the vertical water pipe near the atomizing nozzle, and the vertical water pipe is connected to the template through the connecting buckle.
[0023] With this structural design, the end near the atomizing nozzle is fixed to the template via a connector to prevent the reaction force or vibration that may be generated when the nozzle is working from changing the position of the vertical water pipe. The connector ensures the stability of the nozzle and the accuracy of the spraying direction, thereby guaranteeing the maintenance effect.
[0024] Preferably, the height of the vertical water pipe is greater than the height of the template.
[0025] With this structural design, the vertical water pipes extend downwards from the circumferential water pipes, and the height of the vertical water pipes is greater than the height of the formwork. This ensures that the water mist is sprayed onto the surface of the concrete section below the formwork, guaranteeing the curing quality of the concrete.
[0026] Preferably, the vertical water pipe is connected to the circumferential water pipe via a tee connector.
[0027] Preferably, it also includes a water supply pipe and a fogging machine. The circumferential water pipe is connected to the fogging machine through the water supply pipe. The fogging machine is equipped with a time relay, which controls the switching on and off of the fogging machine. The time relay is turned on once every 2 hours, and each time it lasts for 15 minutes.
[0028] With this structural design, the atomized water flow generated by the fogging machine is stably delivered to the circumferential water pipe through the water supply pipe, and then distributed to the vertical water pipe and atomizing nozzles, ensuring that the water mist can evenly cover the surface of the bridge piers and improve the curing effect. The time relay equipped in the fogging machine enables the automated operation of the spraying system, reducing the operational burden on construction personnel, improving the regularity and consistency of curing, ensuring that the concrete receives adequate moisture in the early hardening stage, and avoiding problems such as water loss or cracking due to untimely curing.

The circumferential water pipe can be directly and conveniently attached to the top of the formwork, avoiding the hassle of installing circumferential water pipes at height and improving the ease of installation of the spraying device.
[0031] 2. This utility model provides a template system with a spraying device, in which a vertical water pipe extends downward from a circumferential water pipe and is fitted with an atomizing nozzle at the end.

[0044] Example 1
[0045] like Figures 1-4 As shown, this embodiment provides a formwork system with a spraying device, including several formworks 1, which enclose a pier casting cavity. Specifically, the formwork 1 can be a flip formwork, slip formwork, or climbing formwork commonly used in the construction of high bridge piers. The pier casting cavity can be a closed or semi-closed space for pouring concrete, formed by multiple formworks.
[0046] Also includes:
[0047] Circular water pipe 2 surrounds the pier casting cavity formed by template 1, and is hung on the top of template 1.
[0048] Specifically, several brackets 5 can be installed on the top of the template 1 of this application. For example, connection holes can be reserved on the top of the template 1, and the brackets 5 can be bolted to the template 1. The circumferential water pipe 2 is hung on the brackets 5.
[0049] The bracket 5, as a specialized support structure, effectively supports the upper walkways, fences, ladders, and other structures, while also providing a reliable attachment point for the circumferential water pipe 2. The circumferential water pipe 2 is directly attached to the bracket 5, fully utilizing its stability to ensure the sprinkler system will not shift or detach during construction, thus guaranteeing system reliability and maintenance effectiveness. Furthermore, by attaching the circumferential water pipe 2 to the bracket 5, cumbersome high-altitude fixing operations are avoided, significantly reducing the difficulty and time required for pipe installation, improving construction efficiency, and alleviating the labor intensity of construction workers.
[0050] Furthermore, such as Figure 2 As shown, the template system with a spraying device provided in this embodiment also includes: a walkway slab 6, which is installed on the top of the corbel 5, and a circumferential water pipe 2 located between the walkway slab 6 and the template 1. Specifically, taking... Figure 2 For example, the circumferential water pipe 2 is located between the walkway slab 6 and the template 1. That is, the walkway slab 6 is not in direct contact with the template 1. Instead, the walkway slab 6, the corbel 5, and the template 1 form an upward-facing concave space. The circumferential water pipe 2 is arranged in this concave space, making full use of this area, avoiding additional occupation of construction space, and maximizing the use of the limited construction environment. The structural design of the concave space plays a natural limiting role for the circumferential water pipe 2, effectively preventing the circumferential water pipe 2 from shifting or shaking during construction, thereby ensuring its positional stability.
[0051] Several vertical water pipes 3 are provided, one end of which is connected to a circumferential water pipe 2, and the other end of each vertical water pipe 3 is fitted with an atomizing nozzle 4. Specifically, as shown... Figure 1 As shown, the vertical water pipe 3 can be a downward extension of the circumferential water pipe 2.
[0052] Furthermore, such as Figure 1 As shown, vertical water pipes 3 are spaced apart along the circumferential water pipes 2. Specifically, the spacing between adjacent vertical water pipes 3 can be 100±20CM, with a preferred spacing of 100CM.
[0053] With this structural arrangement, the vertical water pipes 3 are evenly arranged at certain intervals along the circumferential water pipes 2, ensuring that the water flow can cover all areas of the bridge pier surface through the atomizing nozzles 4. This avoids spray dead zones or water flow concentration in a certain area, thereby achieving all-round uniform curing of the bridge pier surface and reducing plastic shrinkage cracks caused by local water loss. Preferably, the spacing between adjacent vertical water pipes 3 is 100±20CM, which can effectively reduce plastic shrinkage cracks caused by uneven curing.
[0054] Furthermore, such as Figure 2 As shown, the atomizing nozzle 4 is directed towards the cast-in-place bridge pier. Specifically, for example, the atomizing nozzle 4 can be configured as a universal nozzle structure. The nozzle body can be connected to the vertical water pipe 3 via a ball joint. The orientation of the atomizing nozzle 4 can be pre-adjusted during installation. Directing the atomizing nozzle 4 towards the cast-in-place bridge pier ensures that the water mist is sprayed directly onto the concrete surface, maximizing the curing effect, preventing the water mist from dispersing into unrelated areas, reducing water waste, and improving the targeting and efficiency of the spraying.
[0055] Furthermore, such as Figure 2 , Figure 3 As shown, the template system with a spraying device provided in this embodiment also includes a connecting buckle 7. The connecting buckle 7 is located at the end of the vertical water pipe 3 near the atomizing nozzle 4, and the vertical water pipe 3 is connected to the template 1 through the connecting buckle 7. Specifically, the connecting buckle 7 can be a U-bolt, which can pass through the connecting hole on the template 1 and be fixedly connected to the template 1. With this structural arrangement, the end near the atomizing nozzle 4 is fixed to the template 1 through the connecting port, preventing the reaction force or vibration that may be generated when the nozzle is working from changing the position of the vertical water pipe 3. The connecting buckle 7 ensures the stability of the nozzle and the accuracy of the spraying direction, thereby ensuring the maintenance effect.
[0056] Furthermore, the height of the vertical water pipe 3 is greater than the height of the formwork 1. The vertical water pipe 3 extends downward from the circumferential water pipe 2, and its height is greater than that of the formwork 1. This ensures that the water mist is sprayed onto the surface of the concrete section below the formwork 1, thus guaranteeing the curing quality of the concrete.
[0057] Furthermore, such as Figure 1 , Figure 2 , Figure 4 As shown, the vertical water pipe 3 is connected to the circumferential water pipe 2 through a tee connector 8.
[0058] Furthermore, the template system with a spraying device provided in this embodiment, such as... Figure 1 As shown, the system also includes a water supply pipe 9 and a fogging machine 10. The circumferential water pipe 2 is connected to the fogging machine 10 via the water supply pipe 9. The fogging machine 10 can be a fogging machine with a built-in booster pump, and its water storage tank can be a 3000L plastic tank. The fogging machine 10 is equipped with a time relay, such as an Omron H3CR-A series solid-state timer. The time relay controls the switching on and off of the fogging machine 10, turning on every 2 hours for 15 minutes each time. The atomized water flow generated by the fogging machine 10 is stably delivered to the circumferential water pipe 2 via the water supply pipe 9, and then distributed to the vertical water pipe 3 and atomizing nozzles 4, ensuring that the water mist can evenly cover the surface of the bridge pier, improving the curing effect. The time relay equipped in the fogging machine 10 enables automated operation of the spraying system, reducing the operational burden on construction personnel, improving the regularity and consistency of curing, ensuring that the concrete receives adequate moisture in the early hardening stage, and avoiding water loss or cracking problems caused by untimely curing.
[0059] The template system with a spraying device provided in this embodiment has a circumferential water pipe 2 that surrounds the top of the pier casting cavity formed by the template 1, which can evenly distribute the water flow to all directions of the pier. This circumferential arrangement avoids the problem of uneven water column distribution due to gravity or wind interference in traditional spraying methods, ensuring the uniformity of spraying in the horizontal direction; the circumferential water pipe 2 can be directly and conveniently hung on the top of the template 1, avoiding the trouble of installing the circumferential water pipe 2 at high altitude, and improving the convenience of spraying device installation.
[0060] Vertical water pipe 3 extends downwards from circumferential water pipe 2, and atomizing nozzle 4 is installed at its end. This structure allows water to be sprayed evenly from top to bottom, covering the entire surface of the concrete-poured pier section. Atomizing nozzle 4 transforms the water flow into a fine mist, significantly increasing the spraying area and uniformity, making it particularly suitable for the high-altitude maintenance needs of high piers.
[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
