Slurry overflow prevention clamping slot type cylindrical formwork plate and construction method

Abstract

The invention discloses a slurry overflow prevention clamping slot type cylindrical formwork plate and a construction method and belongs to the technical field of building cylindrical formwork plates.The slurry overflow prevention clamping slot type cylindrical formwork plate at least comprises two circular arc formwork plate bodies, first connecting parts are fixedly connected to the two ends ofthe two circular arc formwork plate bodies, first connecting holes are formed in the first connecting parts, reinforcing rib plates and connecting steel plates are fixedly connected to the outer walls of the two circular arc formwork plate bodies, second connecting parts are fixedly connected to the two ends of one circular arc formwork plate body, second connecting holes, positioning grooves andflow blocking grooves are formed in the two second connecting parts, third connecting parts are fixedly connected to the two ends of one circular arc formwork plate body, third connecting holes, positioning parts and flow blocking parts are arranged on the two third connecting parts, fourth connecting parts are connected in the third connecting holes and the corresponding second connecting holesin a matched mode, the positioning parts are matched with the positioning grooves, the flow blocking parts are matched with the flow blocking grooves, slurry overflowing and leaking at joints of cylindrical formwork plates can be effectively prevented in concrete construction, and meanwhile the perpendicularity of concrete and the construction quality can be ensured.

Description

technical field [0001] The invention belongs to the technical field of cylindrical formwork for construction, and in particular relates to an anti-spill grooved cylindrical formwork and a construction method. Background technique [0002] At present, in many domestic construction projects, the frame columns are in the form of cylinders. During construction, in order to increase the turnover rate of formwork and improve the forming effect of concrete, cylindrical formwork is usually used in projects. During the construction of the cylindrical formwork, it is necessary to butt joints in the vertical direction and the circumferential direction, but the existing cylindrical formwork cannot achieve a good seamless butt joint at the joints, resulting in stubble joints when the column concrete is poured. The concrete at the place will have the phenomenon of grout leakage, which will have a serious impact on the forming effect of the concrete, making the concrete column look and fee...

Problems solved by technology

During the construction of the cylindrical formwork, it is necessary to butt joints in the vertical direction and the circumferential direction, but the existing cylindrical formwork cannot achieve a good seamless butt joint at the joints, resulting in stubble joints when the column concrete is poured. The concrete at the place will have the phenomenon of grout leakage, which will have a serious impact on the forming effect of the concrete, making the concrete column look and feel poor after forming

Especially for clear-faced concrete columns that have been formed once without secondary plastering, the phenomenon of grout leakage will directly lead to poor visual effects, and subsequent manual polishing is required, which is time-consuming and laborious
