Problems solved by technology
In the past, in the process of strengthening the side beam support formwork, the traditional formwork binding construction technology was commonly used. This traditional construction technology and reinforcement system device has certain limitations, and it cannot effectively solve the bending strength of the upper side of the side beam. Insufficient problem, which caused the bending strength of the outer formwork on the upper opening of the structural side beam during the construction of the side beam to be insufficient to resist the pressure of the newly poured concrete and the load generated when the side beam concrete was vibrated
As a result, the side beams often expand the mold, and it is difficult to guarantee the size of the structural side beams. In particular, the size deviation of the upper edge of the side beams is large, which seriously affects the quality and appearance of the concrete structure project. It has become a major project quality problem in concrete sub-projects

Embodiment Construction
[0013] With reference to the accompanying drawings, its structure is described in detail.
[0014] exist figure 1 with figure 2 Among them, one end of the pull screw 5 is connected to the bent steel root by welding, and the other end is provided with a mountain-shaped clip 6 and a nut 7. One end of the bent steel root is connected to the corresponding screw rod, and the other end is fixed on the metal sheet 1 by welding, corresponding to The screw rod, bent steel root and metal sheet are welded to form an integrated structure. The length of the double-sided welding seam 4 between the pull screw and the curved steel root is ≥ 10 cm to ensure the firmness of the welding. The reinforcing device has a novel structure and is simple to manufacture. A pair of pull screw rods and bent steel roots are directly spot-welded after being welded, and a mountain-shaped card and a nut are put on the metal sheet provided with two symmetrical fixing holes. During the strengthening construct...

Abstract
The invention relates to a boundary beam upper-port anti-expansion mold reinforcing device, which comprises a metal sheet, a bent steel root, an opposite-pull screw rod and a W-shaped clamp, wherein one end of the opposite-pull screw rod is connected with the bent steel root by welding, and the W-shaped clamp and a screw rod are sleeved at the other end of the opposite-pull screw rod; one end of the bent steel root is connected with the opposite-pull screw rod, and the other end of the bent steel root is connected with the metal sheet by welding; and the opposite-pull screw rod, the bent steel root and the metal sheet form an integrated structure by welding. The reinforcing device is novel in structure and firm and simple in manufacturing; the opposite-pull screw rod and the bent steel root are welded together and then directly welded on the metal sheet provided with two symmetrical round holes; and by using the anti-expansion mold reinforcing device in the process of reinforcing a boundary beam supporting mold, the sectional dimension of a structure boundary beam after molding can be effectively ensured, the upper-port mold expansion of the structure boundary beam can be prevented, and the engineering quality can be guaranteed, so the aim of increasing working efficiency and economic benefit is fulfilled.
Description
technical field [0001] The invention relates to an anti-expansion mold reinforcement device at the top of a side beam, which is mainly aimed at reinforcement measures for building construction formwork support for preventing the expansion of the top mouth of a side beam at a construction site. The device is an innovation of the side beam reinforcement device in traditional building construction. Background technique [0002] With the acceleration of the modernization of cities in our country, stretches of high-rise buildings have sprung up, and the public is paying more and more attention to the quality of construction projects. The quality of projects is directly related to their use effects and also directly affects The safety of people's lives and property. [0003] The construction quality of construction projects, especially residential construction projects, has been widely concerned and valued by the society. The quality of construction projects is directly related to...
