By arranging connecting pieces 500 at both ends of the second side plate 220, when two adjacent high arch dam inverted suspended body customized concrete formworks 100 are positioned by means of the concave-convex grooves, the connecting pieces 500 of the two adjacent high arch dam inverted suspended body customized concrete formworks 100 are correspondingly fitted, and then the locking piece 600 is passed through the two connecting pieces 500 of the two adjacent high arch dam inverted suspended body customized concrete formworks 100 in sequence, thereby connecting the main bodies 200 of the two adjacent high arch dam inverted suspended body customized concrete formworks 100, and fixing the two adjacent high arch dam inverted suspended body customized concrete formworks 100.

[0059] The present application also provides a method for installing a custom concrete formwork for an inverted suspended body of a high arch dam, such as Figures 1 to 5 As shown in the figure, the installation method of customized concrete formwork for the inverted suspension of high arch dam includes:

[0060] The main body 200 of the high arch dam inverted suspension body customized concrete formwork 100 is obtained by processing;

[0061] A protrusion structure 300 is provided at one end of the body 200, and a groove structure 400 is provided at the other end of the body 200;

[0062] Transporting multiple high arch dam inverted suspension body customized concrete formworks 100 to the dam top platform;

[0063] The installation is performed by hoisting, so that the protruding structure 300 of one of the customized concrete templates 100 for the inverted suspension of the high arch dam is snapped into the groove structure 400 of the other customized concrete template 100 for the inverted suspension of the high arch dam.

[0064] The above-mentioned method for installing the customized concrete formwork for the inverted body of the high arch dam is as follows: first, a model of the body 200 of the customized concrete formwork 100 for the inverted body of the high arch dam is designed by software, and the body 200 is obtained by processing according to the designed model; then, a protruding structure 300 and a groove structure 400 are respectively arranged at both ends of the body 200 of the processed customized concrete formwork 100 for the inverted body of the high arch dam; after the preparation of the customized concrete formwork 100 for the inverted body of the high arch dam is completed, a plurality of prefabricated customized concrete formworks 100 for the inverted body of the high arch dam are transported to the dam top platform for installation; a crane is used to first set one on the foundation, and then another customized concrete formwork 100 for the inverted body of the high arch dam is hoisted and set on the foundation, and the protruding structures 300 and the groove structures 400 of the two adjacent customized concrete formworks 100 for the inverted body of the high arch dam in the foundation are snapped together, so as to quickly install and position the customized concrete formwork 100 for the inverted body of the high arch dam, speed up the installation efficiency and construction progress, and reinforce the formwork as soon as possible, reduce the pressure of the automobile crane on the formwork installation, and reduce the construction cost.

[0065] Furthermore, after the two adjacent layers of the custom concrete formworks 100 for the inverted suspended bodies of the high arch dam are clamped, it also includes: the connecting pieces 500 of the two custom concrete formworks 100 for the inverted suspended bodies of the high arch dam are sequentially passed through by the locking piece 600 to preliminarily connect the two adjacent custom concrete formworks 100 for the inverted suspended bodies of the high arch dam. After the two adjacent custom concrete formworks 100 for the inverted suspended bodies of the high arch dam are positioned in the form of concave and convex grooves, the connecting pieces 500 of the two adjacent custom concrete formworks 100 for the inverted suspended bodies of the high arch dam are correspondingly fitted, and at this time, the two connecting pieces 500 of the custom concrete formworks 100 for the inverted suspended bodies of the high arch dam are sequentially passed through by the locking piece 600, thereby connecting the two adjacent custom concrete formworks 100 for the inverted suspended bodies of the high arch dam.

[0066] Specifically, after the two adjacent high arch dam inverted suspension bodies are initially connected, the surveyors perform lofting according to the design structure line and finally reinforce the locking piece 600. The locking piece 600 is first used for preliminary fixation, and then the locking piece 600 is finally reinforced according to the lofting results of the surveyors.

[0067] It should be noted that the initial fixation means that although the nut 620 is not tightened to the preset position, the nut 620 still has a certain locking effect.

[0068] Specifically, when processing the customized concrete formwork 100 for the inverted suspension of a high arch dam:

[0069] Processing concrete panels;

[0070] Plastic film and thermal insulation blankets are used for heat preservation and moisture retention, and the concrete panels are cured until the concrete panels reach the designed strength;

[0071] Steel structure is welded on the back of concrete panels designed to reach preset strength.

[0072] When processing the customized concrete formwork 100 for the inverted body of the high arch dam, firstly, according to the shape of the inverted body of the high arch dam, it is reasonably layered and divided into blocks, the shape and corresponding dimensions of the concrete formwork are designed, and the customized drawings of the concrete formwork for the inverted body of the high arch dam are issued; then, according to the customized drawings of the inverted body concrete formwork, the manufacturer prefabricates concrete panels of different models and sizes. After the prefabrication of the concrete panels, plastic films and thermal insulation blankets are used in time to keep them warm and moist. At the same time, the inverted body concrete panels are cured. After the concrete reaches the designed strength, the concrete formwork steel structure back frame is welded.

[0073] Specifically, after the custom concrete formwork 100 for the inverted suspension of the high arch dam is prefabricated, the structural integrity of the custom concrete formwork 100 for the inverted suspension of the high arch dam is inspected, and the custom concrete formwork 100 for the inverted suspension of the high arch dam is transported to the dam top platform after passing the inspection. After the custom concrete formwork 100 for the inverted suspension of the high arch dam is prefabricated, the structural integrity of the custom concrete formwork 100 for the inverted suspension of the high arch dam is inspected, and only the custom concrete formwork 100 for the inverted suspension of the high arch dam that passes the inspection can be transported to the dam top platform.

[0074] In summary, a method for installing a customized concrete formwork for an inverted suspended body of a high arch dam comprises the following specific steps:

[0075] Step 1: According to the shape of the inverted body of the high arch dam, reasonably divide the blocks into layers, design the shape and corresponding dimensions of the concrete formwork, and issue the customized drawings of the concrete formwork of the inverted body of the high arch dam;

[0076] Step 2: According to the customized drawings of the inverted suspended concrete formwork, the manufacturer prefabricates concrete panels of different models and sizes. After the concrete panels are prefabricated, plastic films and thermal insulation blankets are used in time to keep them warm and moist. At the same time, the inverted suspended concrete panels are cured until the concrete reaches the designed strength, and then the concrete formwork steel structure back frame is welded;

[0077] Step 3: After the concrete formwork is prefabricated, it is pre-installed by a truck crane to inspect the integrity of the prefabricated concrete structure. After passing the inspection, it is lifted by the truck crane onto a flatbed truck and transported to the dam top platform;

[0078] Step 4: After the customized concrete formwork is transported to the dam top platform, it is hoisted to an empty space in the installation warehouse by a cable crane for storage in order to facilitate later installation;

[0079] Step 5: The customized concrete formwork is installed by using a car crane. The upper customized concrete formwork and the bottom customized concrete formwork adopt a concave-convex groove form (i.e., a convex structure 300 is provided at the first end of the body 200, and a concave groove structure 400 is provided at the second end of the body 200), which can achieve rapid positioning. Bolt 610 holes are provided on the back frame steel plate (on the connecting piece 500). After the bolt 610 holes of the upper and lower layers of the formwork are aligned, the operator quickly installs the bolt 610 for preliminary fixing.

[0080] Step 6. After the initial reinforcement of the customized concrete formwork is completed, the surveying personnel will lay out according to the designed structural lines to improve the accuracy of the formwork installation and finally reinforce the bolts 610.

[0081] The customized concrete formwork for the inverted suspended body of a high arch dam of the present application and its installation method, the body design of the customized concrete formwork 100 for the inverted suspended body of the high arch dam is mainly composed of two parts: the convex and concave groove positioning of the angle steels at the top and bottom of the concrete panel and the positioning structure of the back frame steel plate bolts 610. The overall positioning with the upper layer of customized concrete formwork can be achieved through the convex and concave groove positioning structure of the angle steels of the concrete panel, and the positioning structure of the back frame steel plate bolts 610 can realize the rapid positioning and reinforcement of the upper and lower layers of customized concrete formwork, thereby reducing the positioning time of the formwork hoisted by a car crane or a tower crane and the efficiency of welding the upper and lower layers of the formwork back frame by steel plates, thereby improving the efficiency of formwork positioning and reinforcement construction.

[0082] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0083] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
