Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology and relates to a precast concrete base slab ring beam reinforcement binding frame. Background Technology
[0002] In building construction, ring beams are commonly used as load-bearing components for precast concrete slabs. Ring beams are reinforced concrete structures, with their reinforcement cage consisting of multiple layers of circumferential main bars, interspersed with multiple stirrups. The quality of the ring beam reinforcement binding directly affects the overall safety and durability of the building structure. Currently, the reinforcement binding construction of ring beams generally relies on manual control of the bar spacing and positioning, which suffers from problems such as poor bar positioning accuracy, uneven binding, low construction efficiency, and cumbersome procedures, making it difficult to meet the dual requirements of construction quality and schedule. Summary of the Invention
[0003] The purpose of this utility model is to address the above-mentioned problems by providing a precast concrete base slab ring beam reinforcement binding frame, which enables precise positioning and efficient binding of reinforcement.
[0004] The technical solution of this utility model is as follows:
[0005] A precast concrete base slab ring beam reinforcement binding frame is characterized by: two uprights, each upright having multiple stiffening plates welded to its lower sidewall, the bottom edge of each stiffening plate being flush with the lower end face of the upright, and one side being welded to the upright plate; multiple limiting channel steels welded to one sidewall of each upright, each limiting channel steel being longitudinally arranged transversely along the upright with its slot facing upward, the multiple limiting channel steels being distributed vertically at intervals along the upright, the spacing between adjacent limiting channel steels being set according to the layer spacing of the circumferential main reinforcement of the precast concrete base slab ring beam; a circumferential main reinforcement support rod is erected between every two limiting channel steels of the same height on the two uprights, with both ends of each circumferential main reinforcement support rod supported in the slots of the two limiting channel steels respectively.
[0006] This utility model has a simple structure and uses steel materials such as channel steel and steel pipes available on the construction site for welding, resulting in low manufacturing costs. Multiple layers of circumferential main reinforcement support rods are pre-set on the jig according to the layer spacing of the circumferential main reinforcement of the ring beam. When the ring beam reinforcement is tied, each layer of circumferential main reinforcement is supported on the respective layer of circumferential main reinforcement support rods, which can achieve precise positioning of the circumferential main reinforcement and ensure the quality of reinforcement tying.

[0008] Figure 2 This is a schematic diagram of one usage state of this utility model;
[0009] Figure 3 yes Figure 2 A magnified view of a portion of the image. Detailed Implementation
[0010] like Figure 1 As shown, this utility model includes two uprights 1, which can be made of channel steel or square steel. Multiple stiffening plates 2 are welded to the lower side wall of each upright. The bottom edge of each stiffening plate is flush with the lower end face of the upright, and one side is welded to the upright plate. The stiffening plates can distribute the force on the lower end of the upright and play a stabilizing role to prevent the upright from tilting.
[0011] Multiple limiting channel steels 3 are welded to one side wall of each upright 1. Each limiting channel steel is arranged longitudinally along the horizontal direction of the upright with its slot facing upward. The multiple limiting channel steels are distributed at intervals along the vertical direction of the upright. The spacing between adjacent limiting channel steels is set according to the layer spacing of the circumferential main reinforcement of the precast concrete base slab ring beam. A circumferential main reinforcement support rod 4 is erected between every two limiting channel steels 3 of the same height on the two uprights 1. The two ends of each circumferential main reinforcement support rod 4 are respectively supported in the slots of the two limiting channel steels 3.
[0012] In a specific implementation of this utility model, to prevent the circumferential main rib support rod from slipping off the limiting groove rod, a limiting plate 5 can be welded to the end face of each limiting channel steel 3 on each upright rod facing the same direction.
[0013] This utility model is used for binding the reinforcing bars of ring beams, where multiple jigs are used in conjunction. The jigs are arranged according to the shape of the ring beam, such as... Figure 2 , Figure 3 The diagram shows the usage state of a circular ring beam reinforcement binding. Multiple jigs are arranged according to the circular outline of the ring beam. First, the bottom layer circumferential main reinforcement support rods are installed on each jig. The prepared bottom layer circumferential main reinforcement 6 is placed one by one on the circumferential main reinforcement support rods 3 of each jig. The spacing of the circumferential main reinforcement 6 in the same layer is adjusted. Then, the upper layer circumferential main reinforcement support rods and circumferential main reinforcements are installed layer by layer to achieve precise positioning of each circumferential main reinforcement 6. The stirrups 7 are then tied to complete the ring beam reinforcement binding.
[0014] After the ring beam reinforcement is tied, a crane is used to lift the ring beam reinforcement as a whole until it is separated from the circumferential main reinforcement support rod. Then the circumferential main reinforcement support rod is pulled out from the jig, and the ring beam reinforcement is lifted off the jig.
