Example Embodiment

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] refer to Figure 1~3 As shown, the joint fastener of the cylindrical wood formwork of the present invention is mainly composed of the inner column hoop 11 and the outer column hoop 12 sleeved on the outside of the inner column hoop 11. Seam position, to solve the problem that the reinforcement and verticality of the joints of the cylindrical wood formwork are not easy to control.

[0025] The inner column hoop 11 is composed of multiple arc-shaped plates 111. The interior of the multiple arc-shaped plates 111 is enclosed to form an accommodating space 110 for the cylindrical wooden formwork 20. The arc-shaped plates 111 are made of 5 mm thick steel plates , with a height of 500 mm. In this embodiment, the inner column hoop 11 is divided into four arc-shaped plates 111 . An adjustment fastening structure 14 for adjusting the a...

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 ...
