Embodiment 1

[0047] Such as Figure 4 , Figure 6 As shown, the present invention provides a mosaic anti-overturning limiting device for mast lifting construction, the limiting device includes a square bottom plate 3, an arc-shaped first arc-shaped plate 4 with an arc center angle of 0-180°, and a wrapping layer 6 and a protective layer 7, the first arc-shaped plate 4 is arranged on a group of opposite sides of the square bottom plate 3, and the two ends of the first arc-shaped plate 4 are welded and fixed between the bottom plate 3; the first arc-shaped The outer surface of the plate 4 is provided with a wrapping layer 6, and the inner surfaces of the two first arc-shaped plates 4 are welded with first stiffening plates 10; there are at least three first stiffening plates 10 arranged in parallel and spaced on the two first arc-shaped plates 4 on the inner side. The anti-overturning limiting device provided by the present invention can also be provided with a second stiffening plate 11 o...

Embodiment 2

[0049] see Figure 5 As shown, a mast lifting construction mosaic anti-overturning limit device is the same as that in Embodiment 1, except that the arc-shaped plate is U-shaped. The two ends of the U-shaped second arc-shaped plate 13 are welded and fixed to the bottom plate 3 . Name the anti-overturning limiting device containing the U-shaped second arc-shaped plate 13 as 2# limiting device 2.

[0050] Embodiments 1 and 2 The inlaid anti-overturning limit device for mast lifting construction has a simple structure, ingenious design, easy fabrication and installation, and good universality. The layout of the mosaic anti-overturning limit device effectively ensures the construction safety and installation quality, and also saves the construction cost. The arc-shaped plate can be an arc-shaped first arc-shaped plate 4 with an arc center angle of 0-180°, and the arc-shaped plate can also be a U-shaped second arc-shaped plate 13 . Different types of arc-shaped plates can make t...

Embodiment 3

[0052] Such as figure 1 , figure 2 , image 3 As shown, another aspect of the present invention provides a concrete mast cylinder with a mast lifting construction mosaic anti-overturning limiting device, including a concrete mast cylinder 9 and an anti-overturning limiting device arranged on the inner wall of the cylinder through an expansion bolt 5 device; the top of the concrete mast cylinder 9 is provided with a first square hole, the bottom of the concrete mast cylinder 9 is provided with a second square hole, and between the first square hole and the second square hole is a square channel with a continuously variable section; the second The side length of one square hole is smaller than the side length of the second square hole.

[0053] There are at least two sets of anti-overturning limiting devices. The first group of anti-overturning limiting devices is evenly spaced on the inner wall of the concrete mast cylinder 9, on the side close to the first square hole; the se...

Abstract

The invention discloses an embedded-type overturn-preventing limiting device for mast hoisting construction and a construction method of the device. The limiting device comprises a square bottom plate, arc plates, a covering layer and a protection layer; the arc plates are arranged on a pair of opposite sides of the upper surface of the square bottom plate, and the two ends of the arc plate are fixedly connected with the bottom plate; the covering layer is arranged on the outer side face of the arc plate, and the outer side face of the covering layer is coated with the protection layer. The arc plates are first arc plates or second arc plates; the first arc plates are in an arc shape, and the arc center angle is 0-180 degrees; the second arc plates are in a U shape. The covering layer is an engineering plastic alloy plate. The device is simple in structure, novel in design, easy to manufacture and universal. Through the arrangement of the embedded-type overturn-preventing limiting device, the construction safety and construction quality are effectively guaranteed, and the construction cost is also reduced. By means of the construction method, the situation can be avoided that sincean inverted-installation hoisting construction technology is usually adopted for existing construction of an television tower towering steel mast, the gravity center of the steel mast is above the hoisting suspension point.

Description

technical field [0001] The invention relates to the technical field of mast auxiliary equipment, in particular to a mast lifting construction mosaic anti-overturning limiting device and a construction method thereof. Background technique [0002] In recent years, the lifting construction technology for the installation of TV tower steel masts has been widely used, and the construction technology has become increasingly mature. The steel mast of the tower crane is inserted into the concrete mast cylinder to a certain length, and the inversion method is generally used for lifting construction. [0003] However, in special cases, for example, after each section of the steel mast is upside-down in the concrete mast barrel and raised to a certain height, then the butt joint welding of the adjacent steel mast is performed, and the steel mast is assembled from top to bottom to form a whole. Lifting and hoisting to the design height, due to the shrinkage of the section size of the s...
