Embodiment 1

[0027] combine Figure 1 to Figure 3 The structural composition of the pointed roof formwork system of the tower concrete structure of the present invention is illustrated. The steep slope slope of the pointed roof in this embodiment is greater than 45°.

[0028] A formwork system for a pointed roof of a tower concrete structure, comprising a base formwork 10 and a surface formwork 20; the base formwork 10 is fixed by a full hall support bent frame 6, and the base formwork 10 has the same slope as the large-slope inclined roof of the pointed roof to be poured; the surface The layer formwork 20 is arranged in parallel above the bottom formwork 10, and the two are connected by fastening components to form a cavity. The thickness of the cavity is consistent with the thickness of the sloped roof. There is a pouring trough (not shown).

[0029] Specifically, the formwork system for the pointed roof of the tower concrete structure of the present invention is achieved by setting do...

Abstract

The invention discloses a tower concrete structure pointed roof formwork system and a construction method, relates to the technical field of formwork systems, and is used for solving the problem thatthe compactness of concrete is difficult to control when concrete is poured on a pointed roof large-gradient sloping roof. The formwork system comprises a bottom-layer formwork and a surface-layer formwork. the bottom-layer formwork is fixed through a full framing bent frame and has the same gradient as the large-gradient sloping roof of a pointed roof to be poured; and the surface-layer formworkis arranged above the bottom-layer formwork in parallel, the surface-layer formwork and the bottom-layer formwork are connected through a fastening assembly to form a cavity, and pouring grooves are formed in the surface-layer formwork at certain intervals from bottom to top. Two layers of formworks, namely, the bottom-layer formwork and the surface-layer formwork, are arranged, and the pouring grooves are reserved in the surface-layer formwork, the pouring grooves are formed in a segmented mode to achieve layered pouring, and therefore it is well guaranteed that on-site sharp-topped sloping roof concrete discharging is achieved, and concrete vibrating work is efficiently and orderly conducted.

Description

technical field [0001] The invention relates to the technical field of formwork systems, in particular to a formwork system and a construction method for a pointed roof formwork system of a concrete structure of a tower building. Background technique [0002] According to the existing data, the main forms of the formwork system of domestic sloping roofs are: one is to use steel structure to establish frame formwork for steep and high sloping roofs; The sloped roof of the concrete structure adopts single and double-sided formwork. The traditional method of double-sided formwork is to use limit screws to fix the double-sided formwork. The bottom formwork uses wooden beams as the back flute, and the bottom of the back flute is supported by steel pipes. The steel pipe is fastened and pressed tightly. However, for the steep and high concrete structure sloping roof, there are some defects in the existing technology. [0003] Therefore, how to provide a formwork system and const...
