Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of spiral rib installation construction, in particular to a spiral rib fixing device. Background Technique
[0002] Embedded sleeves and reserved holes are important components in precast concrete components. To strengthen the crack resistance of the concrete around the embedded sleeves and reserved holes, spiral ribs are usually designed around the embedded sleeves and reserved holes. During the construction of precast concrete components, spiral ribs need to be installed at positions such as sleeves, casings, and reserved holes to strengthen the protection of these positions. The traditional construction method mainly involves workers using binding wires or spot welding to fix the spiral ribs to the steel bars. The main drawbacks of this construction method are the large influence of human factors. The fixing method is inefficient during construction, relying on the proficiency of the operators. When the fixing is not firm, the spiral ribs are extremely likely to displace during the concrete pouring and vibration process, causing various quality problems such as unqualified protective layers and exposed steel bars, affecting the quality of the segment entity. In addition, this construction method has a high labor intensity, low work efficiency, time-consuming and laborious, and the welding fumes during welding construction cause harm to the health of construction workers. Content of the Utility Model

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions:
[0005] A spiral rib fixing device includes a first buckle end, a second buckle end, a snap fastener, and a reinforcement mechanism. The outer surface of the first buckle end is fixedly connected to the outer surface of the second buckle end. The outer surface of the snap fastener is fixedly connected to the outer surface of the second buckle end. A card slot is provided on the outer surface of the second buckle end. The reinforcement mechanism includes a bent support plate. An active connecting rod is sleeved inside the bent support plate.

Beneficial effects
[0011] The utility model provides a spiral rib fixing device, which has the following beneficial effects:
[0012] (1) For this spiral rib fixing device, through the cooperation among the first buckle end, the second buckle end and the fastening buckle, not only the installation efficiency is improved. During installation, only the buckle needs to be closed with fingers, which is simple and convenient to operate and can be operated by any worker. Moreover, it has a better installation effect, enabling the spiral rib to be fixed on the embedded sleeve or the formed hole steel bar, without displacement due to concrete pouring and vibration. After demoulding, it can achieve zero error compared with the design. It also has better economic effects, which can greatly reduce the number of laborers used. Especially for construction projects with a large number of spiral ribs, compared with the traditional wire fixing, it can reduce the number of operating workers by half, and compared with the welding fixing, it can greatly reduce the number of welders, reducing the installation cost. In addition, it can protect the health and safety of construction workers, solving the problems that traditional welding fixing will generate a large amount of welding fumes that are harmful to human health and potential safety hazards such as electric shock and falling from height that may occur when moving the welding machine and connecting wires during the welding process.
[0013] (2) For this spiral rib fixing device, through the reinforcement mechanism, the elastic force of the support spring can make the bent support plate and the movable support plate jointly press the second buckle end, further improving the firmness of the second buckle end and extending the service life of the whole device.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] As Figures 1-4 shown, the spiral rib fixing device includes a first buckle end 1, a second buckle end 2, a snap fastener 3 and a reinforcement mechanism 5. The outer surface of the first buckle end 1 is fixedly connected to the outer surface of the second buckle end 2. The outer surface of the snap fastener 3 is fixedly connected to the outer surface of the second buckle end 2. A card slot 4 is formed on the outer surface of the second buckle end 2. The reinforcement mechanism 5 includes a bent support plate 51. An active connecting rod 52 is sleeved inside the bent support plate 51. The output end of the active connecting rod 52 is fixedly connected to an active support plate 53. A support spring 54 is sleeved on the outer surface of the active connecting rod 52.
[0021] The card slot 4 is arranged opposite to the snap fastener 3. The inner surface of the card slot 4 is in extrusion fit with the outer surface of the snap fastener 3. The first buckle end 1 is small on the outside and large on the inside, presenting a 4 / 7 circle. The reinforcement mechanism 5 is arranged at the side of the outer surface of the second buckle end 2. The end of the support spring 54 is fixedly connected to the outer surface of the active support plate 53. The end of the support spring 54 away from the active support plate 53 is fixedly connected to the outer surface of the bent support plate 51.
[0022] A guiding chute 55 is formed on the outer surface of the bent support plate 51. A fixed slider 56 is fixedly connected to the outer surface of the active support plate 53. The outer surface of the fixed slider 56 is slidably connected to the inner surface of the guiding chute 55.
[0023] The spiral rib fixing device is composed of a first buckle end 1, a second buckle end 2, a snap fastener 3 and a reinforcement mechanism 5. The first buckle end 1 is small on the outside and large on the inside, presenting a 4 / 7 circle, and its size matches the diameter of the spiral rib. The size of the second buckle end 2 matches the embedded sleeve or the formed hole steel bar to be clamped. The snap fastener 3 is a one-way fixing snap. Before installing the spiral rib, first put the second buckle end 2 on the embedded sleeve or the formed hole steel bar, and then close the snap fastener 3 to firmly fix the spiral rib fixing device to the embedded sleeve or the formed hole steel bar. Then put the spiral rib on the embedded sleeve and the formed hole steel bar, and fix the spiral rib with the first buckle end 1. When fixing, at least three spiral rib fixing devices need to be used and arranged evenly in a 360° circle. The first buckle end 1 needs to fix the spiral rib at intervals with one positive and one negative orientation, and keep the spiral rib at a designed distance from the embedded sleeve and the formed hole steel bar. Finally, pull the movable support plate 53 so that the distance between the opposite surfaces of the movable support plate 53 and the bent support plate 51 matches the width at the side of the second buckle end 2. The fixed slider 56 slides along the guiding chute 55. After placing the reinforcement mechanism 5 at the side of the second buckle end 2, release the movable support plate 53. At this time, under the support of the second buckle end 2, the support spring 54 is still in a stretched state. The elastic force of the support spring 54 can make the bent support plate 51 and the movable support plate 53 jointly press the second buckle end 2, further improving the firmness of the second buckle end 2 and extending the service life of the whole device.
