Reinforcement system of cylindrical wood formwork and splice joint fastener

Abstract

The invention discloses a reinforcement system of a cylindrical wood formwork and a splice joint fastener. The splice joint fastener comprises an inner side column loop and an outer side column loop. The inner side column loop comprises a plurality of arc-shaped plate bodies, a containing space for containing the cylindrical wood formwork is defined by the arc-shaped plate bodies, and an adjusting fastening structure for adjusting the arc-shaped plate body to control the containing space is arranged outside each arc-shaped plate body. The outer side column loop is arranged outside the inner side column loop in a sleeving mode. A plurality of positioning clamping grooves which are formed in the height direction of the cylindrical wood formwork and used for inserting positioning inserts are formed in the outer wall of the outer side column loop. The inner side column loop and the outer side column loop form a dual-layer column loop structure; on one hand, the problems that vertically-adjacent cylindrical wood formworks are not firm in splice joint and not easy to reinforce are solved through the inner side column loop with the adjusting fastening structure; on the other hand, the perpendicularity of the vertically-adjacent cylindrical wood formworks is controlled through the outer side column loop with the positioning clamping grooves and the positioning inserts.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a reinforcement system and a patchwork fastener for a cylindrical wood formwork. Background technique [0002] At present, the cylindrical shaped wooden formwork is a new type of formwork recommended in China. This formwork has many advantages such as good strength, many turnover times, and good appearance quality after concrete pouring. Strict, the verticality is not easy to control, the reinforcement is not easy and other defects are prominent. If the control is not proper, it is easy to cause the verticality of the concrete to exceed the standard. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a reinforcement system and a seam fastener for a cylindrical wooden formwork that is reinforced at the joints of cylindrical shaped wooden formwork, which can ensure the verticality of the upper and lower cylindrical ...

[0002] At present, the cylindrical shaped wooden formwork is a new type of formwork recommended in China. This formwork has many advantages such as good strength, many turnover times, and good appearance quality after concrete pouring. Strict, the verticality is not easy to control, and the defects such as reinforcement are not easy to highlight. If the control is not proper, it is easy to cause the verticality of the concrete to exceed the standard.
