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

Embodiment 1

[0037] like Figure 1 to Figure 8 As shown in the figure, a kind of anti-spill grooved cylindrical formwork includes two arc-shaped formworks 1, and the two ends of the two arc-shaped formworks 1 are welded and fixed with first connectors 2, and the first connectors 2 are provided with There is a first connecting hole 3, and the upper and lower arc-shaped templates 1 are assembled by using the first connecting hole 3 on the first connecting piece 2 and connecting bolts, and the outer walls of the two arc-shaped templates 1 are fixedly connected with Rib plate 5 and connecting steel plate 6, connecting steel plate 6 is arranged in the circumferential direction, connecting steel plate 6 is a crescent-shaped structure with narrow ends and wide middle, the middle part of connecting steel plate 6 is fixedly connected with reinforcing rod 16, and the outer side of reinforcing rod 16 is sleeved There are pull rings 17 . Since the stress in the middle of the arc-shaped formwork 1 is ...

Embodiment 2

[0043] like Figure 9 As shown, a construction method of anti-overflow grout slot type cylindrical formwork includes the following steps:

[0044] Step 1. Preparatory work: pour concrete base and pre-embed bolts (to provide convenience for the installation of the cylindrical formwork on the bottom floor), bind the column reinforcement of the designed column and complete the acceptance, and install the fixed pulley 21 in the surrounding area of ​​the designed column Hoist 22 and fixed rod 23;

[0045] Step 2. Assembling the arc-shaped formwork 1: use the positioning piece 13 to insert into the positioning groove 9, and at the same time ensure the cooperation of the flow blocking groove 10 and the flow blocking piece 14, so as to realize rapid assembly, and move the positioning piece 13 to the hook and the second connecting piece 7 Snapping prevents deviation when connecting the second connecting piece 7 and the third connecting piece 11, and the connecting portion 151 of the f...

Abstract

The invention discloses an anti-overflow slurry slot type cylindrical formwork and a construction method, belonging to the technical field of architectural cylindrical formwork. It includes at least two arc-shaped templates, the two ends of the two arc-shaped templates are fixedly connected with the first connecting piece, the first connecting piece is provided with a first connecting hole, and the outer walls of the two arc-shaped templates are fixed The stiffener plate and the connecting steel plate are connected, and the two ends of an arc-shaped formwork are fixedly connected with the second connecting piece, and the two second connecting pieces are provided with the second connecting hole, the positioning groove and the flow resistance groove. Both ends of an arc-shaped template are fixedly connected with a third connecting piece, and the two third connecting pieces are provided with a third connecting hole, a positioning piece and a flow blocking piece, and the third connecting hole and the second connecting hole are matched and connected. There is the same fourth connecting piece, the positioning piece cooperates with the positioning groove, and the flow blocking piece cooperates with the flow blocking groove, which can effectively prevent the joints of the cylindrical formwork from overflowing and leaking during concrete construction, and at the same time ensure the verticality of the concrete. degree and construction quality.

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...
