[0032] The present invention is described in detail below in conjunction with the accompanying drawings: The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention. Embodiment 1

[0033] Please refer to Figure 1 and Figure 3 The first embodiment of the present invention provides a shear wall formwork system 100 with a continuous arched door opening, comprising vertical support columns 110 located on both sides of each arched door opening of the shear wall, an arched support 120 assembled and connected between the vertical support columns 110 on both sides of each arched door opening and matching the arching degree of the corresponding arched door opening, a vault bottom form 130 detachably connected to the arched support 120 and matching the arching degree thereof, and a vertical support column 110 located between the vertical support columns 110 and connected to the arched door opening. The door opening wall side mold 140 connected by the pull bolt 141 has a notch at the lower end thereof that matches the arching degree of the arch bottom mold 130, and the lower end of the door opening wall side mold 140 is detachably connected to the arch bottom mold 130 on the corresponding side, and a holeless wall side mold 150 that is upwardly directed along the lower end of the vertical support column 110 is provided between the door opening wall side molds 140 of adjacent arched door openings, and a wall end side mold 160 is provided between the outermost wall side molds at both ends. At this time, the outermost wall side molds at both ends can be the door opening wall side mold 140 or the holeless wall side mold 150, and are arranged according to construction needs, wherein door opening and holeless refer to arched door openings, and do not include other openings. The door opening wall side formwork 140 and the non-hole wall side formwork 150 can be a single formwork or multiple formworks. The door opening wall side formwork 140 and the tension bolts 141 on both sides of the wall of each arched door opening of the shear wall constitute a tie formwork system; similarly, the non-hole wall side formwork 150 on both sides of the wall of the shear wall can also be a tie formwork system formed by the tension bolts 141, or other formwork structures. In order to improve the reliability of the connection between the arch bottom formwork 130 and the arch support 120, the two ends of the arch bottom formwork 130 can be set on the vertical support columns 110 on their respective sides.

[0034] Please refer to Figure 2In order to realize the assembled connection of the arch support 120 and facilitate the demolding, the shear wall formwork system 100 with a continuous arched door opening provided in the first embodiment of the present invention is provided with a slot 111 for the arch support 120 to be inserted and connected on each of the vertical support columns 110, and the two ends of the arch support 120 are respectively inserted into the slots 111 of the vertical support column 110 connected to the side, and also includes a locking rod 112, and the locking rod 112 passes through the slot 111 through the vertical support column 110 and is tightened on the arch support 120. At this time, the locking rod 112 can be a threaded rod, and the corresponding vertical support column 110 has a threaded hole for the threaded rod to connect. In order to realize the rapid disassembly and assembly of the arch support 120, the locking rod 112 passes through the slot 111 and the arch support 120 to lock the arch support 120 on the vertical support column 110. At this time, the locking rod 112 can be a pin or a dowel, and the corresponding arch support 120 and the vertical support column 110 on both sides of the slot 111 have through holes for the pin or dowel to be inserted and connected. The locking rod 112 can fix the arch support 120 to prevent displacement or separation from the vertical support column 110.

[0035] Please refer to Figures 4 to 5 In the shear wall formwork system 100 with a continuous arched door opening provided in the first embodiment of the present invention, in order to facilitate the detachable connection between the arch bottom form 130 and the arch support 120, at least two inverted hooks 136 distributed on different sides are hingedly and symmetrically arranged on the arch bottom form 130. After the inverted hooks 136 are rotated, they are hooked on the arch support 120 on the corresponding side or detached from the arch support 120. In order to facilitate hoisting and reduce the hoisting weight of the single component, there can be three arch supports 120. At this time, the two inverted hooks 136 are respectively hooked on the arch supports 120 when they rotate downward. Figure 5 When the two inverted hooks 136 rotate upward, they fall off the arch support 120 so that the arch bottom mold 130 is removed from the arch support 120.

[0036] Please refer to Figure 1 , Figures 3 to 5In order to improve the versatility of the arch bottom form 130 and adapt to the arching degree of various arched door openings, the shear wall formwork system 100 with continuous arched door openings provided in the first embodiment of the present invention, the arch bottom form 130 is an assembled formwork with adjustable arching degree, and the assembled formwork includes at least one assembly unit, each of which includes a support screw 131 and a plurality of first sheets 132 and a plurality of second sheets 133 staggered and serially connected to the support screw 131, and the support screw 131 does not expose the outermost first sheet 132 and / or second sheet 133. The first sheet 132 and the second sheet 133 are tightly fitted without gaps. The length and arching degree of the assembled formwork with adjustable arching degree composed of an assembly unit or a plurality of assembly units can be adjusted by adjusting the number of the first sheet 132 and the second sheet 133. The support screw 131 does not expose the outermost first sheet 132 and / or second sheet 133, in order to achieve seamless connection between multiple assembly units. In order to facilitate the fastening of the first sheet 132 and the second sheet 133 connected in series on the support screw 131, the support screw 131 may include an internally threaded rod and an external screw 135 connected thereto, and the first sheet 132 and the second sheet 133 thereon are fastened and seamlessly connected by the threaded internal and external screws.
