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 connecting parts 2, and the first connecting parts 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 fo...

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 upper end of the hook to the hook Engage with the second connecting piece 7 to prevent deviation when connecting the second connecting piece 7 and the third connecting piece 11, and pass ...

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...
