Around it, solidify each layer of concrete slab and its through holes for use as ventilation holes or water supply pipes or lines. The early through hole forming device or template device was only a hollow vertical tube, but the current building slab has a large bearing capacity, so the thickness of the concrete floor slab must be thick, and the hole length of the through hole is long, so that the through hole is formed. The height of the device or formwork device such as the upright cylinder becomes higher and the area of the corresponding concrete is more extensive. In order to avoid the impact of a large amount of poured concrete to compress the through hole forming device or the template device to deform, thereby rupturing the forming of the through hole, some existing through hole forming devices or formwork devices such as the Japanese utility model of the real open flat 5-32586, special Kaiping Various improved technical solutions have been provided in 11-81663 and JP-A-2000-145142, and most of the main structures have an upper cover, a lower cover, a hollow upright cylinder and a long rod-shaped fixing member.

Referring to Figures 2a, 3a and 3b, the fastening assembly 110 includes four separable short curved bodies 120 and four pairs of fasteners 128, wherein the four separable short curved bodies 120 are along the The outer circumferential surface 1020 of the cylindrical wall 102 constitutes an annular arrangement, wherein each short curved body 120 has an arc of π/2 (arc length / radius = π/2), and each short curved body 120 integrally forms a first A connecting end 124 and a second connecting end 126. The first connecting end 124 and the second connecting end 126 are respectively connected to the opposite ends of the short curved body 120, and the first connecting end 124 and the second connecting end 126 are respectively A

hole

1242, 1262 is formed. Before constituting the annular arrangement, the second connection end 126 of the short arcuate body 120 of one of π/2 radians is interconnected with the first connection end 124 of another adjacent short arcuate body 120 of π/2 radians 120. , connected in series to a long curved body 122 having π radians, and so on, and then serially connecting two other short curved bodies 120 of π/2 radians until the four short curved bodies 120 are connected in series As shown in FIG. 3b, the first connecting end 124 and the second connecting end 126 at both ends of the long curved body 122 having 2π radians are connected to each other for connection; The four curved walls 120 of π/2 radians are connected one by one, and the arc of the long curved body 122 is expanded from π to 2π, and as a result, as shown in FIG. 3b, the long curved body 122 is made.
