Embodiment 1

[0025] Example 1 is basically as attached figure 1 Shown:

[0026] A foldable serrated punching board, such as figure 1 As shown, it includes two rectangular steel plates 10 and a stainless steel hinge 13. The size of the steel plate 10 is 400×120×3mm. The steel plate 10 is punched with punching holes 12. There are two rows of punching holes 12 in each row. There are 8 holes in each row. It is a circular through hole, the hole diameter of the punching hole 12 is 10mm, and the spacing between the punching holes 12 is 50mm. The two long sides of the steel plate 10 are cut into a zigzag shape, and the teeth 11 on the two long sides correspond to each other. The size of 11 is set to 25×25mm, and the spacing between serrations 11 is 100mm. One of the short sides of the two steel plates 10 is connected by a stainless steel hinge 13. The size of the hinge 13 is 2 inches. The hinge 13 is firmly welded between the two steel plates 10, and the two steel plates 10 and the hinge 13 form a fo...

Embodiment 2

[0030] The difference between embodiment 2 and embodiment 1 is that the punching hole 12 is a rectangular through hole of 20×3mm, and the rectangular through hole makes the flowing mortar into a strip shape. After the steel plate 10 is removed, a strip-shaped rough surface can be naturally formed on the cement, without Picking, the texture formed by rectangular through holes is more natural than the texture formed by circular through holes.

Embodiment 3

[0032] The difference between embodiment 3 and embodiment 1 is: combination figure 2 with image 3 As shown, two fixing blocks 14 are welded between a pair of adjacent serrations 11 on a long side of the steel plate 10, and a cylindrical blind hole is provided in the fixing block 14, and the openings of the two blind holes are arranged oppositely. A cylindrical rotating rod 21 is connected between the two blind holes. Both ends of the rotating rod 21 are coaxially provided with cylindrical protrusions 22 that match the blind holes. The rotating rod 21 can rotate relative to the fixed block 14. The rotating rod An A-shaped support plate 20 is fixedly connected to 21. The support plate 20 is welded by steel bars. The support plate 20 can follow the rotating rod 21 to rotate relative to the fixed block 14, so that the support plate 20 can act as a diagonal brace. The plate 20 can prevent the steel plate 10 from toppling, and the steel plate 10 does not need to be manually restric...

Abstract

The invention relates to the technical field of building construction, and specifically discloses a foldable sawtooth punched-plate. The foldable sawtooth punched-plate comprises two rectangular steelplates and one stainless steel hinge, punched holes are punched in the steel plates, the steel plates are cut into serrated shapes along two long edges, the two short edges of the two steel plates are connected by the stainless steel hinge, the hinge is firmly welded between the two stainless steel plates, and the foldable sawtooth punched-plate is formed by the two steel plates and the hinge. The foldable sawtooth punched-plate aims to solve the problems of inaccurate positioning of reinforcing bar, too large or too small thickness of a reinforcing bar protective layer, poor civilized construction and inability of turnover using of a cement interception board.

Description

Technical field [0001] The invention relates to a foldable sawtooth punching board, more specifically, it is a standardized concrete construction joint and a post-pouring belt interceptor. Background technique [0002] At present, there are only two types of well-known concrete construction joints and post-pouring belt interception: [0003] 1. Directly adopt the quick-and-easy closing net, intercept the concrete and leave it in the concrete permanently, so that the concrete surface that has been poured twice can be isolated, and the overall force cannot be formed, which affects the structural safety; at the same time, the economic benefit is not high and the cost is high. [0004] 2. The use of wooden squares or formwork to intercept the steel bars can not accurately fix the steel bars, which will easily cause the steel bars to be misaligned and the thickness of the steel bar protection layer is too large or too small, which affects the durability of the structure; Chisel, poor sit...
