Description

Flexible formwork

Technical Field

The utility model relates to a building templates system, concretely relates to flexible template.

Background

At present, when a pile head, a stand column or a shear wall is poured, a layer of wood formwork needs to be integrated on the periphery of a reinforcement cage, and after the pile head, the stand column or the shear wall is poured and formed, the wood formwork is dismantled. Generally, a wood formwork requires a constructor to cut a wood board according to the size of a pile head, a column or a shear wall on site, and a layer of wood purlin and steel bars is applied to the formwork to reinforce the formwork. The setting mode of the wood template is labor-consuming and time-consuming, can only meet the requirement of using the template with one specification, has poor universality and seriously wastes wood in the manufacturing process.

In order to improve the universality, the Chinese intellectual property administration publishes a radian-adjustable pile head wood template and a pile head template fixing system in 2018, 11, 30.A pile head wood template comprises a template body, a plurality of vertical grooves arranged along the height direction of the template body are arranged on the back surface of the template body at intervals, and the template body can be pulled by external force to bend into an arc shape or a circular shape by taking any one vertical groove as an axis. A plurality of vertical cavities that set up on this template body provide the advantage for it bends, nevertheless in order to guarantee the intensity of whole template body, avoid simultaneously bending in-process template and use vertical groove part rupture, it needs many people to cooperate when bending, bends comparatively labouriously, and the design is comparatively difficult, can only satisfy the use of circular post or pile head template, if use it in rectangle or other opposite sex templates, can have the problem of rupture or design difficulty. In addition, when the template with the structure is manufactured, the manufacturing requirement on the vertical groove is higher, and the qualified rate is difficult to ensure. In order to meet the purpose that the template is easy to bend, the thickness of the template cannot be too thick, so that the template is low in strength, a thin inner template needs to be arranged in the template during installation, and a wood purlin is arranged outside the inner template to improve the thickness of the template, so that the template meets the strength requirement of the template. Meanwhile, the smoothness and the wear resistance of the wood template are low, so that the wood template is not beneficial to demolding and short in service life.

Based on the reasons, the applicant wants to design a flexible template which has the advantages of long service life, easy demoulding, high template strength and low manufacturing difficulty and can meet the installation requirements of various special-shaped templates.
