Description

Pre-buried buckle formula template stop device

Technical Field

The utility model belongs to the technical field of templates and scaffolds, and particularly relates to a pre-buried buckle type template limiting device.

Background

In C type material field engineering, the cross-sectional scale of the cast-in-place concrete wall of feed bin body barricade engineering is great: the height is 15-20 m, and the wall thickness is 1-2m. During construction, the retaining wall is generally divided into a plurality of horizontal construction layers according to the standard of the height of about 3m of each layer along the vertical direction, then the horizontal direction construction is finished firstly by adopting a large template technology according to the unit of each horizontal construction layer, and then the layer-by-layer construction is carried out from low to high.

In the construction process of the large template, when the lower template is removed and the upper template starts to support the template, the lower foot of the upper template needs to be provided with a stable positioning supporting point. The traditional construction method is that a temporary positioning support frame is arranged on a counter-pulling screw (or a counter-pulling screw preformed hole) reserved or specially arranged in the construction of a lower layer structure, and the temporary positioning support frame is used as a lower foot positioning support point of an upper layer template. This approach has many advantages and also significant disadvantages:

(1) because of the influence of various factors in construction, reserved or specially arranged opposite-pull screws and holes can not always meet the requirement of temporary positioning support, and various conditions such as breakage, bending, fracture, blockage and the like can be caused.

(2) When the opposite-pulling screws of the lower-layer large template are arranged in an economic mode, the distance between the uppermost opposite-pulling screw and the upper surface of the concrete is larger, generally larger than 300mm, and the instability risk of the temporary positioning support frame erected on the opposite-pulling screw is larger; if the opposite-pulling screw is specially arranged, a large amount of steel for the opposite-pulling screw is consumed because the wall body is thicker.

(3) The reserved opposite-pull screw rods and holes are restricted by the condition that the subsequent utilization is needed, and the lower-layer template cannot be cut off when the lower-layer template is disassembled, so that the construction difficulty of disassembling the lower-layer large template is increased, and the work efficiency is reduced; the scaffold inner row vertical rods and the wall surface need larger operation space, and the distance between the corresponding wall and the scaffold must be increased, so that the safety risk is increased.
