Description

Technical Field

[0001] The utility model belongs to the field of building materials, in particular to an arc-shaped axil template structure. Background Art

[0002] During the construction of some subways, the use of an arc-shaped structure for the base slab has become a new main structural technology. However, in actual construction, the pouring of concrete at the arc-shaped corners of the base slab is difficult, exhaust is difficult, and the arc-shaped corners have special surface shapes and structural form limitations, resulting in the quality of the concrete appearance being difficult to control. The surface is prone to quality defects such as honeycombed surfaces and misalignment.

[0003] The arc-shaped armpit corner formwork used in the prior art usually adopts a wood formwork or a steel formwork in combination with a water-based release agent or an oil-based release agent, but there will be wood grain on the concrete surface of the wood formwork. The steel formwork uses a water-based and oil-based release agent, which has a good effect compared with the oil-based one. There are relatively fewer bubbles, but there are also bubbles, and the bubbles in the steel formwork are larger than those in the wood formwork. The experimental blocks are made by a homemade arc vibrator + a flat plate vibrator. There are still many bubbles in the arc section, and the effect is general. In order to ensure the appearance quality of the arc section, a water-permeable and breathable formwork cloth is used for the construction of the test piece. Judging from the completion effect of the test block, the water-permeable and breathable formwork cloth is suitable for the construction of the arc-shaped armpit corner. The arc-shaped armpit corner has no bubbles and the surface is slightly rough. It is easy to install and does not require the construction of a release agent. Moreover, after the formwork is removed, the water-permeable and breathable membrane can be attached to the concrete surface, which has the effect of membrane maintenance. However, at present, the water-permeable and breathable formwork cloth is connected to the formwork by aerosol bonding, which causes troubles in the later removal of the formwork. If the aerosol bonding is not used, the water-permeable and breathable formwork cloth cannot be fixed on the formwork, which affects the later cement pouring. Utility Model Content
