[0002] With the rapid development of China's nuclear power industry, AP1000, as an advanced third-generation nuclear power technology, has attracted much attention. In terms of the amount of civil engineering construction, there are huge differences between AP1000 and general civil construction projects. Taking a single AP1000 unit as an example, the steel bar usage is about 55,000 tons, the formwork area reaches about 380,000 square meters, and the concrete volume is about 250,000 cubic meters. These engineering quantity values far exceed those of general civil construction projects, significantly increasing the difficulty of construction safety management in nuclear power projects. In particular, extremely high requirements are put forward for the safety performance of key construction materials and components, such as the fixed-type formwork for the straight wall. However, the fixed-type formwork for the straight wall in traditional construction projects is constructed by construction workers in a conventional manner according to the on-site construction progress, for example, the height dimensions of the boards used for the straight wall formwork are the same, and the construction platform is built layer by layer with the scaffold according to the preset height.

[0043] The standard template combination and scaffolding structure are built in a conventional manner. For example, the height dimensions of the templates are consistent, and the scaffolding is used to build the construction platform layer by layer according to the preset height. However, this method cannot adapt to nuclear power civil engineering construction. For example, there are problems with the unreasonable setting of the operation platform in the construction of traditional straight-wall fixed-form templates. For example, for straight-wall templates with height dimensions of 4.88 meters and 6.10 meters, only one operation platform is set in traditional construction, resulting in construction workers having to perform construction operations at a relatively high position, increasing the risk of falling from a height. Moreover, the setting of such a single operation platform is difficult to meet the multi-height operation requirements, making it inconvenient for construction workers to perform operations at different heights and affecting the construction efficiency. Difficult to meet multi-height operation requirements

[0044] To solve the above technical problems, as Figure 1 shown, a method for determining a fixed-form template for a nuclear power straight wall provided by an embodiment of the present application includes S110 to S140.

[0045] S110, obtain the plant building parameters, where the plant building parameters include the straight-wall geometric parameters.

[0046] Since different plant buildings use different models and quantities of fixed-form templates, and during the nuclear power civil engineering construction process, the consumption of fixed-form templates is large. If different models and quantities of fixed-form templates are called according to on-site requirements during the plant building construction process, it is very easy to cause situations where the requirements cannot be met or the calling time is long. Therefore, in the embodiment of the present application, the plant building parameters will be obtained in advance through design planning or design drawings before or at the beginning of the plant building construction. In this way, the models and quantities of the required fixed-form templates can be determined and called in advance.

[0047] Among them, the straight-wall geometric parameters are the shape and size information of the wall. For example, in the embodiment of the present application, the parameters related to the height, width, thickness, shape structure, and gap area of the wall for the construction of the fixed-form template are included, and at the same time, the distance between multiple straight walls, that is, the length of the gap area, is also included.

[0048] S120, determine the position and height dimension of the straight-wall template area according to the straight-wall geometric parameters.

[0049] Among them, the straight-wall template area refers to the wall area where the straight-wall template needs to be set, that is, the area of this area is larger than the smallest-size straight-wall template. The position of the straight-wall template area refers to its position on the wall of the plant building, such as the height from the ground and the horizontal position. When setting the fixed-form template in the straight-wall template area, the horizontal length can be adapted by adjusting the length of the straight-wall template, or multiple straight-wall templates can be spliced in the horizontal direction. Since the height dimension has a greater impact on the construction difficulty, the height dimension of the straight-wall template area is used as the core reference factor.

[0050] S130. Determine the installation position of the first type of operating platform according to the position of the straight wall formwork area.

[0051] Among them, as Figure 2 shown, the position of the first type of operating platform 1 is at the starting height position and / or the ending height position of the straight wall formwork area; it should be noted that according to the position and height dimension of the straight wall formwork area, the same straight wall formwork area can have the first type of operating platform 1 only set at the starting height position, or only set at the ending height position, or have the first type of operating platform 1 set at both the starting height position and the ending height position.

[0052] It should be noted that when the distance between the starting height position of the straight wall formwork area and the ground or the existing platform is greater than or equal to a certain distance, the first type of operating platform 1 needs to be set. If the distance between the starting height position of the straight wall formwork area and the ground or the existing platform is less than a certain distance, at this time, the ground or the existing platform can be used as the first type of operating platform 1.

[0053] For example, if the bottom of the straight wall formwork area is close to the ground or a certain platform, the first type of operating platform 1 may not be set at the starting height position of the straight wall formwork area; for another example, if the top of the straight wall formwork area is the top of the building, the first type of operating platform 1 may not be set at the ending height position of the straight wall formwork area.

[0054] For another example, if the height of the straight wall formwork is 2.44 meters, the first type of operating platform 1 is not set only at the starting height position of the straight wall formwork area; for another example, if the height of the straight wall formwork is 3.66 meters, the first type of operating platform 1 is set at both the starting height position and the ending height position of the straight wall formwork area.

[0055] S140. Determine the height dimension of the straight wall formwork according to the height dimension of the straight wall formwork area, and determine the number of the second type of operating platforms set in the straight wall formwork area according to the height dimension of the straight wall formwork.

[0056] Specifically, if the height dimension of the straight wall formwork is greater than the first preset value, the number of the second type of operating platforms 2 is 1. For example, as Figure 3 shown, the first preset value is 4.88 meters, then the first type of operating platform 1 is set at both the starting height position and the ending height position of the straight wall formwork area, and 1 second type of operating platform 2 is set at the middle position of the straight wall formwork area.

[0057] If the height dimension of the straight wall formwork is greater than the second preset value, the number of the second type of operating platforms 2 is 2, and the second preset value is greater than the first preset value. For example, as Figure 4As shown, the second preset value is 6.10 meters. Then, the first type of operating platform 1 is set at both the starting position and the ending position of the height in the straight wall formwork area, and 2 second type of operating platforms 2 are set at the middle position of the straight wall formwork area.

[0058] S150. Determine the installation positions of the second type of operating platforms according to the number of the second type of operating platforms and the installation positions of the first type of operating platforms.

[0059] Specifically, according to the positions of the first type of operating platforms 1, determine the vertical distance between two adjacent first type of operating platforms 1 and the number of the second type of operating platforms 2 arranged between two adjacent first type of operating platforms 1. In the embodiments of the present application, the starting position and / or the ending position of the height is a regional range, and it is necessary to consider whether there is a special wall structure at this position, or whether there are other devices with position interference. When there is position interference, it is necessary to avoid the special wall structure or the devices with position interference. At this time, the distance between the two first type of operating platforms 1 at the starting position and the ending position of the height is not the height dimension of the straight wall formwork area. Therefore, first determine the vertical distance between two adjacent first type of operating platforms 1, and then arrange the second type of operating platforms 2 arranged between two adjacent first type of operating platforms 1 at preset intervals between two adjacent first type of operating platforms 1.

[0060] In addition, since inclined supports may be provided at the bottom of the first type of operating platforms 1, obtain the design parameters of the inclined supports between two adjacent first type of operating platforms 1, and then adjust the installation positions of the second type of operating platforms 2 according to the design parameters of the inclined supports to avoid the inclined supports, so as to prevent the inclined supports from affecting the installation of the second type of operating platforms 2, or affecting the operation activities of the construction workers on the second type of operating platforms 2 subsequently.

[0061] In some embodiments of the present application, if the height dimension of the straight wall formwork is greater than the second preset value, obtain the vertical distance between the second type of operating platform 2 and the first type of operating platform 1 below in the straight wall formwork area; if the vertical distance between the second type of operating platform 2 and the first type of operating platform 1 below in the straight wall formwork area is greater than the safety distance, determine the safety net parameters between the second type of operating platform 2 and the first type of operating platform 1 below. That is, in the straight wall formwork area, if the vertical distance between the second type of operating platform 2 and the first type of operating platform 1 below is too large, a safety net needs to be set to ensure the safety of the construction workers on the second type of operating platform 2 subsequently.

[0062] The embodiment of the present application provides a method for determining a nuclear power straight wall shaped template, which determines the position and height of the straight wall template area according to the straight wall geometric parameters; then determines the installation position of the first type of operating platform 1 according to the position of the straight wall template area, and determines the number of the second type of operating platforms 2 set in the straight wall template area according to the height of the straight wall template area; finally, determines the installation position of the second type of operating platform 2 according to the number of the second type of operating platforms 2 and the installation position of the first type of operating platform 1. The technical solution of the embodiment of the present application can improve the rationality of the operating platform setting, so that construction personnel can work more conveniently at different heights, so as to improve construction efficiency and construction safety.

[0063] In order to solve the above technical problems, Figure 1 As shown, a method for determining a nuclear power straight wall shaped template provided in an embodiment of the present application includes S510 to S530.

[0064] When constructing a high formwork, the traditional tie rod construction method has limitations. Due to the high formwork height, it is difficult for operators to reach the appropriate position to install and remove the tie rods, which not only increases the difficulty of construction, but also poses a greater safety hazard. In this regard, in some embodiments, after determining the installation position of the second type of operating platform 2 according to the number of the second type of operating platform 2 and the installation position of the first type 1, such as Figure 5 As shown, it also includes S510 to S530.

[0065] S510: Obtain a vertical distance between the second type operating platform and the operating platform below.

[0066] Among them, the operating platform includes a first type of operating platform and a second type of operating platform.

[0067] S520: If the vertical distance between the second type operating platform and the operating platform below meets the preset requirement, determine the installation position of the pull rod.

[0068] It should be noted that tie rods need to be set on the straight wall formwork at preset distances. Generally, the length and setting density of the tie rods are determined based on the thickness and height dimensions of the strength. The vertical distance between the second type of operating platform 2 and the operating platform below meets the preset requirements, which means that the vertical distance between the second type of operating platform 2 and the operating platform below is larger. At this time, multiple tie rods need to be set at the vertical height between the second type of operating platform 2 and the operating platform below. At this time, in order to avoid the installation of the tie rods, the installation position of the tie rods needs to be determined.

[0069] S530, determining the installation position of the template hanging bench according to the installation position of the pull rod.

[0070] Among them, by setting the formwork hanging stool 3, the construction problem of the tie rods of the straight wall formwork with a large height dimension can be solved, enabling the operators to conveniently reach the appropriate positions for the installation and disassembly of the tie rods; avoiding the construction difficulties caused by the mismatch between the formwork system and the positions of the wall tie rods, and improving the construction convenience and efficiency.

[0071] Specifically, as Figure 6 shown, the formwork hanging stool 3 includes a double-channel steel strap 31 and a pedal 32 that are connected to each other. Among them, the double-channel steel strap 31 is fixedly arranged on the double-channel steel, the double-channel steel is arranged vertically and parallel to the straight wall formwork, the pedal 32 can be stepped on by the operators, and the formwork hanging stool 3 is made of high-quality steel and is firmly connected to the straight wall formwork or the double-channel steel through special connectors, providing a stable operation platform for the construction workers.

[0072] It should be noted that the shape and size of the formwork hanging stool 3 can be optimized according to the structure and construction requirements of the straight wall formwork to ensure that the formwork hanging stool 3 can be conveniently installed on the straight wall formwork and does not affect the normal use of the straight wall formwork. When installing the formwork hanging stool 3, special connectors are used to firmly connect the formwork hanging stool 3 to the straight wall formwork to ensure its stability and safety.

[0073] It should be noted that the formwork hanging stool 3 is used to assist the operators in passing and standing, and cannot be used as a long-term conventional operation platform. Moreover, when the operators use the formwork hanging stool 3, they need to fasten the safety belts according to the regulations to ensure their own safety.

[0074] The traditional formwork system selection does not fully consider the characteristics and requirements of different parts of nuclear power construction. At the nuclear power site, the construction conditions of different construction parts vary greatly, such as the gap area, the annular continuous space inside the plant building, etc. Using a unified formwork system cannot meet the actual construction requirements, resulting in increased construction difficulty and corresponding improvement of safety risks.

[0075] In this regard, in some embodiments, after obtaining the plant building parameters, it further includes: determining the length of the gap area according to the straight wall geometric parameters; if the length of the gap area is less than the third preset value, then determining the installation positions of the straight ladder, the anti-falling line device and the anti-falling device in the suspended area according to the positions of the first type of operation platform 1 and the second type of operation platform 2 in the gap area. As Figure 6 shown, when the length of the gap area is less than the third preset value, it indicates that the distance between the two straight walls is small. At this time, if a safety net is set on the straight wall formwork, since the safety net is a flexible material, the safety net will flutter with the wind, which is very likely to affect the construction of the other straight wall, resulting in the inability to set the safety net. At this time, the installation positions of the straight ladder, the anti-falling line device and the anti-falling device in the suspended area are determined according to the positions of the first type of operation platform 1 and the second type of operation platform 2 in the gap area to ensure the safety of the construction workers.

[0076] In some embodiments, after obtaining the factory building parameters, it further includes: determining the height dimension of the suspended area according to the straight wall geometric parameters; if the height dimension of the suspended area meets the first preset condition, determining the installation parameters of the safety net, the installation parameters of the step ladder, and the installation parameters of the formwork hanging stool 3 in the suspended area.

[0077] For example, when installing the straight wall formwork, first build the wall hanging rack. For example, the wall hanging rack is constructed with I-beams, and the installation of the wall hanging rack should be carried out strictly in accordance with the design requirements to ensure its structural stability and firmness. Then install the formwork. During the installation process, pay attention to the verticality and horizontality of the formwork, and use measuring instruments for real-time monitoring and adjustment. After the installation is completed, hang the safety net from the operating platform to the hanging rack, and the hanging of the safety net should be tight and firm. Install a fall arrester at the upper and lower passage openings of the formwork. The installation position of the fall arrester should be accurate and the connection should be firm. Lay the steel walkway board and install the steel guardrail on the operating platform to ensure that the installation quality of the passage panel and the protective railing meets the relevant standard requirements. Set up the climbing ladder according to the specifications, and the installation of the climbing ladder should be firm and reliable, and be closely connected to the formwork or the wall structure.

[0078] Among them, it is necessary to equip the safety net, the step ladder or the formwork hanging stool 3 according to the height and the height difference between the hanging rack and the tie rod. For a suspended area with a relatively high height and a large height difference between the hanging rack and the tie rod, for example, when installing the straight wall formwork suspended area with a height dimension of 6.10 meters or 4.88 meters, when the external hanging rack and the formwork are combined for construction, there are lack of effective safety protection measures. Once a worker accidentally stumbles, it is extremely easy to have a high-altitude falling accident, seriously threatening the life safety of the construction workers. At this time, it is necessary to give priority to equipping the safety net and the formwork hanging stool 3 to ensure the safety of the construction workers. During the equipping process, reasonable combination and installation should be carried out according to the actual situation to ensure that various protective facilities can work together and play the maximum safety guarantee role. For example, the first preset condition is that the height dimension of the suspended area is greater than 2 meters.

[0079] In some embodiments, the factory building parameters further include internal space parameters; if the internal space parameters meet the second preset condition, determine the installation parameters of the construction scaffolding and the safety net parameters of the construction scaffolding in the factory building according to the internal space parameters.

[0080] In factory building construction, there are some building structures in special situations, which result in the inability to build an operation platform. For example, there are small rooms inside, or irregular wall surfaces on the exterior walls. Specifically, for example, the area of the small room is too small to build an operation platform, or after building the operation platform, the space of the small room is further reduced, making it impossible for construction workers to carry out normal construction operations. In this case, scaffolding construction is adopted. When erecting the scaffolding, according to the internal space parameters, the installation parameters of the construction scaffolding and the safety net parameters of the construction scaffolding inside the factory building are determined, and it is required to operate strictly in accordance with relevant specifications and standards to ensure the structural stability and firmness of the scaffolding and that it can bear the weight of construction workers and construction equipment. At the same time, necessary safety protection facilities such as railings and safety nets should be set on the scaffolding to ensure the safety of construction workers.

[0081] It should be noted that after building the straight wall formwork, operation platform or scaffolding, the number and position of the climbing ladders need to be specified according to different construction scenarios. For example, in the internal annular continuous space of the factory building room, when the perimeter of the annular continuous space is less than or equal to 24 meters, one climbing ladder is set; when the perimeter of the annular continuous space is greater than 24 meters and less than or equal to 48 meters, two climbing ladders are set; when the perimeter is greater than 48 meters, three climbing ladders are set. During the construction on the outer side of the wall, one straight climbing ladder is set every no more than 12 meters of the formwork width. The climbing ladders should be made of high-strength steel, and their structural design should meet the requirements of strength and stiffness. The spacing of the ladder steps should conform to the ergonomic principle to ensure that construction workers can safely and conveniently go up and down. The installation of the climbing ladders should be firm and reliable, and be tightly connected to the formwork or wall structure.

[0082] In addition, the straight wall formwork also needs to be provided with diagonal bracing rods, which include long braces and short braces. The base fixing method of the diagonal bracing rods is to be fixed on the ground with expansion bolts. The specifications and quantities of the expansion bolts should be accurately calculated and determined according to the force-bearing situation of the diagonal bracing rods. The connection position between the diagonal bracing rods and the formwork channel steel straps is reasonably selected according to the structure and force-bearing characteristics of the formwork, and generally bolt connection is adopted to ensure firm and reliable connection.

[0083] It should be noted that the anti-falling device provided in the embodiment of the present application is set at the upper and lower passage openings of the straight wall formwork. The rated load of the anti-falling device should meet the weight requirements of construction workers and carried tools. When installing the anti-falling device, it is necessary to ensure its accurate installation position and firm connection with the straight wall formwork and the channel structure. At the same time, the anti-falling device should be regularly inspected and debugged to ensure that it can play a timely and effective role in case of emergency and ensure the safety of personnel going up and down.

[0084] It should be noted that the safety net provided in the embodiments of the present application should be made of high-strength and high-toughness materials that meet national standards, such as nylon safety nets. During the hanging process, it is necessary to ensure that the tension of the safety net is moderate, without any slack or damage. The fixing points of the safety net should be firm and reliable. Special fixing devices should be used to tightly connect the safety net to the operating platform and the hanging rack to prevent the safety net from falling off. At the same time, the safety net should be regularly inspected and maintained, and the damaged safety net should be replaced in time to ensure that it is always in good working condition.

[0085] The embodiments of the present application also provide a nuclear power straight wall sizing formwork. The installation parameters of the nuclear power straight wall sizing formwork are determined by using the above-mentioned determination method of the nuclear power straight wall sizing formwork.

[0086] The embodiments of the present application provide a method for determining a nuclear power straight wall sizing formwork and the nuclear power straight wall sizing formwork. The method for determining the nuclear power straight wall sizing formwork determines the position and height dimension of the straight wall formwork area according to the geometric parameters of the straight wall; then determines the installation position of the first type of operating platform according to the position of the straight wall formwork area, and determines the number of the second type of operating platforms arranged in the straight wall formwork area according to the height dimension of the straight wall formwork area; finally determines the installation position of the second type of operating platform according to the number of the second type of operating platforms and the installation position of the first type of operating platform. By using the technical solution of the embodiments of the present application, the rationality of the arrangement of the operating platform can be improved, enabling construction workers to work more conveniently at different heights, so as to improve construction efficiency and construction safety, and through optimizing the configuration logic of the operating platform, the topological optimization of the construction path is realized, significantly reducing the risk level of high-altitude operations.

[0087] The above specific embodiments have further elaborated on the purpose, technical solution and beneficial effects of the present application. It should be understood that the above are only specific embodiments of the present application and are not used to limit the protection scope of the present application. Any modifications, equivalent replacements, improvements, etc. made on the basis of the technical solution of the present application shall be included in the protection scope of the present application.
