Embodiment Construction

[0036] A concrete cylindrical formwork system such as figure 1 As shown, the concrete cylindrical formwork system includes a lining circle frame 1, an inner lining plate 2, an outer formwork 3 and an outer hoop 4;

[0037] The inner lining circle frame 1 comprises two semicircular rings 11 butted against each other, and the upper parts of the two ends of the semicircular rings 11 are respectively provided with connecting plates 12 protruding from the outside of the semicircular rings 11 (see diagram 2-1 ), the connecting plate 12 is provided with a bolt hole; the lower part of the semicircular ring 11 is used to cover the inner lining plate 2, and helps the upper end of the inner lining plate 2 to be fixed into a circle. Preferably, the inner lining circle frame 1 is made of aluminum alloy, which is used to check whether the formed cylindrical template is smooth, and helps the upper end of the inner lining plate 2 to be fixed in a circular shape.

[0038] The inner lining pl...

Abstract

Provided is a concrete cylindrical formwork system. The concrete cylindrical formwork system comprises an inner lining round frame, an inner lining plate, an outer formwork and an outer hoop; the inner lining round frame comprises two semicircular rings which are butt-jointed; connecting plates are correspondingly arranged on the upper parts of the two ends of the semicircular rings and are protruded out of the outer sides of the semicircular rings, and bolt holes are formed in the connecting plates; the inner lining plate is an arbitrarily bended thin plate made of a polyvinyl chloride material and is adapted to the size of the concrete cylindrical circumference; the outer formwork is a plastic plate which is adapted to circumference size of the inner lining plate, the inner side of a section of the outer formwork is a smooth face, and the outer side of the section of the outer formwork is provided with vertical rib strips; the outer hoop is a fastening plastic strip with holes formed in one end and sharp corners and teeth arranged on the other end; and the inner lining round frame is placed on the upper end of an inner cylindrical formwork formed by the inner lining plate, the inner cylindrical formwork is wrapped with the outer formwork, and the inner lining plate and the outer formwork are fixed by the outer hoop. According to the concrete cylindrical formwork system, the construction efficiency is improved, using turnover times are increased, and construction cost is reduced.

Description

technical field [0001] The invention relates to a building formwork, in particular to a concrete cylinder formwork system. Background technique [0002] In civil engineering construction, for cylindrical concrete members, the method of supporting formwork usually adopts shaped steel formwork or uses long fir boards to splice steel hoops and wooden hoops, which are either expensive or splicing. The efficiency is low, to a certain extent It affects the construction efficiency and quality. Contents of the invention [0003] The purpose of the present invention is to provide a brand-new concrete cylindrical formwork system, which can improve construction efficiency, increase turnover times and reduce construction cost. The formwork of the cylindrical concrete member is completed by changing the formwork material and a new assembly method. The inner wall of the formwork system of the present invention is smooth and dense, which ensures the pouring quality of the concrete surf...
