Description
Technical Field
The invention belongs to the technical field of building construction, and particularly relates to a reusable deformation-preventing adjustable triangular support frame for a reinforcement cage.
Background
After the bored concrete pile is formed into a hole, a reinforcement cage is processed and installed, and then concrete pouring and other construction processes are carried out, so that a complete pile foundation is finally formed. Before the steel reinforcement cage is installed, a steel reinforcement is required to be processed into the steel reinforcement cage according to the size of a design drawing in a steel reinforcement processing field, then the steel reinforcement cage is transported to the site, and a crane is adopted to hoist the steel reinforcement cage into a hole for installation. The reinforcement cage is respectively provided with a reinforcing rib, a main rib, a spiral stirrup and a positioning rib from inside to outside. Because the steel reinforcement cage is longer, and the diameter is great, easily produces the deformation in transportation, hoist and mount process, so need set up the inside lining at the middle of the steel reinforcement cage every certain length and prevent that the shape support warp in order to prevent the steel reinforcement cage. In the prior construction, the anti-deformation support is generally welded on the reinforcing ribs in a triangular shape formed by two crossed reinforcing bars or three reinforcing bars, and the anti-deformation reinforcing bars are sequentially removed before entering the holes, but the method not only causes a large amount of waste of the reinforcing bars, but also increases the labor cost, and consumes time and labor in the construction process.
Disclosure of Invention
In order to solve the technical problems, the invention provides a reusable deformation-preventing adjustable triangular support frame for a reinforcement cage, which comprises an adjusting screw rod, a round nut, an ear plate, a connecting pin and an outer sleeve, wherein the screw threads at two ends of the adjusting screw rod are opposite in rotation direction, and a rotating device is connected between the screw rods at the two ends; the round nut is matched with threads at two ends; the outer sleeve is sleeved on the screw rod and can move relatively, and the inner side of the outer sleeve is connected with the round nut; the number of the adjusting screw rods is 3, and the two ends of the adjusting screw rods are sleeved with outer sleeves to form a triangular stable structure; the outer side of the outer sleeve is transversely fixedly connected with the lug plates, the lug plates are provided with round holes, and the connecting pins penetrate through the round holes to connect the two lug plates together.
Preferably, the end center of the outer sleeve is provided with a clamping opening.
Preferably, the round nut and the outer sleeve are welded into a whole.
According to the principle that a triangle has stability, the device disclosed by the invention has an obvious effect in the deformation prevention process of the reinforcement cage, and is high in flexibility and turnover utilization rate. Most of the existing steel reinforcement cage deformation preventing devices are 'cross braces', or the steel reinforcement is used to cause waste, or the deformation preventing effect is not obvious when the adjustable 'cross braces' are used for large-diameter steel reinforcement cages. The device is particularly suitable for deformation control of large-diameter pile foundation reinforcement cages.
Each supporting rod of the device is adjustable, an adjustable section is arranged in the middle of each supporting rod, and the adjustable section consists of a positive and negative adjusting wire, a round nut and a rotating device. The positive and negative adjusting wires control the expansion of the adjusting screw rod; the round nut can bear larger axial force and is responsible for locking and fixing the screw rod; the rotating device provides a stress rotating point for tools such as a wrench and the like, and is beneficial to the rotation of the adjusting screw rod. The three components act together, so that flexible and free adjustment of each adjusting rod can be easily realized, the mounting and dismounting are convenient, and the operability is strong.
