Description

Technical Field

[0001] The utility model relates to the technical field of municipal construction, and more specifically to a steel bar binding device used for reinforcing wooden formwork in municipal pipe network projects. Background Art

[0002] As time goes by and the city expands, the original underground pipe network system gradually exposes problems such as insufficient capacity and serious aging. In this context, it is particularly important to seek an advanced construction technology that can not only ensure the safety and quality of the replacement construction of the original pipe position, but also significantly improve construction efficiency. Currently, the construction of pipeline base plates and inspection wells mostly relies on a combination of wooden formwork and steel pipes. The use of formwork is extremely common on construction sites, and wooden formwork is an important member. After the wooden formwork is built, workers will arrange steel bars inside it and inject concrete to form a structure. The inspection well chamber is made up of multiple steel bars interwoven together. The traditional method is for workers to use wire and manually operate tools with hooks or electric binders to tighten the staggered steel bars one by one.

[0003] However, this process presents many inconveniences and challenges: manual tightening is not only time-consuming and labor-intensive, but can also easily lead to hand fatigue and reduce work efficiency; and while electric tie-downs can reduce the physical burden, their high price makes bulk purchase and widespread use impractical, making it difficult to meet the needs of all workers.

[0004] In view of the above problems, the existing structure and defects are studied and improved, and a steel bar bundler for reinforcing wooden formwork in municipal pipe network projects is provided, in order to achieve the purpose of greater practical value. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a steel bar bundler for reinforcing wooden formwork in municipal pipe network projects, so as to solve the problem that ordinary bundlers are not suitable for long-term work and electric bundlers are expensive and costly to use.

[0006] The utility model provides a steel bar binding device for reinforcing wooden formwork in municipal pipe network projects, which is achieved by the following specific technical means:

[0007] A steel bar binder for reinforcing wooden formwork in municipal pipe network projects comprises a rotating telescopic rod, a hook rod is fixed to the bottom end of the rotating telescopic rod, a slide groove is provided on the outer wall of the rotating telescopic rod, a sleeve rod is movably sleeved on the outer wall of the rotating telescopic rod, a handle sleeve is fixed to the outer wall of the sleeve rod, a top cover is fixed to the top of the sleeve rod, a tension spring is fixed to the bottom of the top cover, and a guide rail is fixed to the inner wall of the sleeve rod.

[0008] Furthermore, the guide rail and the slide groove are both arranged in a spiral shape, the guide rail and the slide groove are used in combination, and the number of turns of the slide groove spiral is greater than eight turns.

[0009] Furthermore, a through hole is formed through the top of the top cover, a guide plate is fixed to one side of the bottom of the through hole, and the guide plate and the top cover are arranged in an inclined shape.

[0010] Furthermore, a placement slot is provided in the middle of the top of the rotating telescopic rod, and the bottom end of the tension spring is fixed to the bottom of the inner wall of the placement slot.

[0011] Furthermore, the outer walls of the sleeve rod and the grip sleeve are penetrated by limiting holes, and a plurality of the limiting holes are provided. The plurality of limiting holes are located above the middle of the sleeve rod and the grip sleeve and are arranged vertically and equidistantly.

[0012] Furthermore, a limiting bolt is threadedly connected to the interior of one of the limiting holes, a knob is fixed to one end of the limiting bolt, and the length of the limiting bolt is equal to the radius of the sleeve rod.

[0013] Furthermore, a protrusion is fixed on the top of one end of the hook rod, and the protrusion is arranged in a hemispherical shape.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the utility model, the iron wire is folded in half and placed on the hook rod, and the other end is passed through the steel bar to be tied, and then the other end is also placed on the hook rod. The hemispherical protrusion can be better inserted into the iron wire and the worker will not be injured when inserting the iron wire. Then the grip cover is pulled upward. Through the cooperation of the guide rail and the slide groove, when bundling the steel bars, the worker holds the grip cover tightly with his hand and pulls the sleeve rod upward. The rotatable telescopic rod can be rotated, driving the hook rod to rotate, and the iron wire can bundle the steel bars. Bundling can be performed without rotating the device, thereby reducing the frequency of hand use and reducing fatigue from long-term work.

[0016] 2. In the present invention, the number of turns of the wire is determined according to the diameter of the bundled steel bars, and the limit bolt is inserted into the corresponding limit hole. When the telescopic rod is rotated to reset after the wire is tightened, it can be reset to the position of the limit bolt, avoiding the need to excessively pull the grip cover during next use, thereby achieving the effect of saving effort during work.

[0017] 3. After long-term use, the friction between the guide rail and the slide groove of the utility model increases, and a lot of effort is required to pull the sleeve rod. At this time, a needle is used to extract lubricating oil and inject it into the sleeve rod from the through hole. The lubricating oil is diverted through the guide plate and enters the gap between the sleeve rod and the rotating telescopic rod, thereby achieving the effect of quickly maintaining the device.
