Problems solved by technology

However, the three-dimensional space curved steel formwork trolley is in the construction work of the bending section, and the side formwork and the top formwork are both three-dimensional space hyperboloid structures. Due to the shape of the three-dimensional space structure, the boundary line between the side formwork and the top formwork is a spatial broken line, and conventional settings cannot be adopted. Lateral shrinkage side formwork demoulding, forced demoulding will lead to deformation and distortion of the formwork, the side form cannot be separated from the concrete surface and the top form cannot be demoulded

Embodiment Construction

[0023] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0024] see Figure 1-3 , a three-dimensional curved surface steel mold trolley demoulding anti-interference device, including a longitudinal shaft 8, the longitudinal shaft 8 is located at the top of the side mold 2 and the bottom of the top mold 5, and is connected with the side mold 2 and the top mold 5 through a connecting piece 9. It should be noted that, adopting the structure of the present invention, the position of the longitudinal shaft 8 should not only ensure that the side form 2 rotates around the longitudinal shaft 8, but also ensure that the top of the side form 2 does not contact the side of the lined concrete when the side form 2 rotates. , that is, the top of side form 2 leaves the lining concrete surface. The longitudinal rotating shaft 8 is arranged along the longitudinal length of the steel mold trolley.

[0025] The side mold 2 is ...

Abstract

The invention relates to a three-dimensional space curved face steel-mould trolley demoulding anti-interference device and method. Through longitudinal rotary shafts arranged on the tops of side moulds and the lower portions of a top mould, side mould action oil cylinders at the bottoms of the side moulds contract, the side moulds are rotated towards the inner side with the longitudinal rotary shafts as the axis, and demoulding of a three-dimensional space curved face steel-mould trolley at the bend section can be achieved successfully. The problem that as the boundaries of the top mould and the side moulds are space folding lines due to limitation of the three-dimensional space structural shape, the side moulds cannot contract transversely for demoulding through conventional arrangement is solved. The demoulding quality is high, templates will not twist or deform, the templates will not intervene in lined concrete, and construction safety is guaranteed.

Description

technical field [0001] The invention relates to the field of steel mold trolleys for tunnel construction, in particular to a three-dimensional space curved surface steel mold trolley demoulding anti-interference device and a demoulding method. Background technique [0002] Tunnel lining concrete is generally constructed with a steel formwork trolley. The conventional steel formwork trolley demoulding method is as follows: the boundary line between the side form and the top form is a straight line, and the connection between the side form and the top form is a short pin shaft; The hydraulic cylinder laterally shrinks the formwork to demould, and the top mold is demoulded through the set top mold cylinder lifting the formwork. However, the three-dimensional space curved steel formwork trolley is in the construction work of the bending section, and the side formwork and the top formwork are both three-dimensional space hyperboloid structures. Due to the shape of the three-dimen...
