A control mold for a horse stool iron of a floor reinforcing layer

Abstract

This utility model relates to the field of stirrup technology, specifically disclosing a stirrup control mold for the protective layer of floor slab reinforcement. The mold includes a stirrup with a placement groove at its top, an elastic layer connected to the middle of the placement groove, and a fitting rod at the bottom of the elastic layer. The top of the placement groove also has a fitting groove. Rotating gear shafts are connected to both sides of the placement groove near the fitting groove, and abutment rods are connected to both sides of the placement groove, with one end of each abutment rod connected to the rotating gear shaft. Through the elastic layer and abutment rods in this device, when the reinforcement is placed in the placement groove, its own weight causes the elastic layer to deform and contract downwards, pulling the abutment rods to deflect. This causes the abutment rods to abut against both sides of the reinforcement, thus restricting its lateral movement and preventing it from shifting laterally during pouring, which would affect the pouring process.

Description

Technical Field

[0001] This utility model relates to the field of stirrup technology, and more specifically, to a stirrup control mold for the protective layer of floor slab reinforcement. Background Technology

[0002] Stirrups are used in the pouring of concrete in a floor slab. They are placed between the upper and lower layers of reinforcing bars to support the upper bars, creating a space between them and forming a stable reinforcing bar skeleton to facilitate pouring.

[0003] However, existing trestles simply place the steel bars into the curved groove of the trestle without much restriction when supporting the upper layer of steel bars. The binding method is also inconvenient for adjusting the position of the steel bars, which makes it easy for the steel bars to sway and shift left and right in the curved groove during the pouring process, thus affecting the final pouring and shaping. Utility Model Content

[0004] The purpose of this utility model is to provide a control mold for the reinforcing bar protective layer of floor slabs. This solves the problem that when reinforcing bars are supported, multiple adjustments are required to ensure a stable connection, which can lead to shaking and displacement during the pouring process and affect the pouring.

[0005] This utility model is achieved through the following technical solution: This utility model provides a control mold for the reinforcing bar protective layer of floor slabs, including a reinforcing bar. The top of the reinforcing bar is provided with a placement groove, the middle of the placement groove is connected to an elastic layer, the bottom of the elastic layer is provided with a fitting rod, the top of the placement groove is provided with a fitting groove, and a rotating gear shaft is connected to both sides of the placement groove near the fitting groove. A traction rope is connected to the middle of the rotating gear shaft, and a stop rod is connected to both sides of the placement groove. One end of the stop rod is connected to the rotating gear shaft through the traction rope.

[0006] Preferably, the elastic layer is made of rubber.

[0007] Preferably, the fitting rod is a rod body whose bottom of the elastic layer mates with the fitting groove.

[0008] Preferably, one side of the rotating gear protrudes from both sides of the fitting groove, and the protruding part of the rotating gear meshes with both sides of the fitting rod.

[0009] Preferably, the rotating gear shaft further includes a winding shaft, which is disposed in the middle of the rotating gear shaft.

[0010] Preferably, the winding shaft is a round shaft with a diameter smaller than that of the rotating gear shaft, and the traction rope is wound and connected to the surface of the winding shaft.

[0011] Preferably, the abutment also includes a hinge shaft, one end of which is connected to the hinge shaft, and the abutment is rotatably connected to both sides of the placement groove via the hinge shaft.

[0012] Preferably, a torsion spring is provided at one end of the hinge shaft rotatably connected placement groove, and the hinge shaft is wound and connected to the end of the traction rope away from the winding shaft.

[0013] The technical solution of this utility model has at least the following advantages and beneficial effects: 1. Through the elastic layer and the abutment bar set in the device, when the steel bar is placed in the placement groove, the elastic layer deforms and contracts downward due to its own weight, which will pull the abutment bar to deflect it. This will cause the abutment bar to abut against both sides of the steel bar, thereby restricting the left and right movement of the steel bar and preventing it from shifting left and right during the pouring process, which would affect the pouring.

[0019] The following is combined Figures 1 to 4 This utility model will be described in detail.

[0020] A control mold for a concrete cover for floor slab reinforcement includes a trestle 1. The top of the trestle 1 is provided with a placement groove 101. An elastic layer 1011 is connected to the middle of the placement groove 101. A fitting rod 1012 is provided at the bottom of the elastic layer 1011. A fitting groove 1013 is provided at the top of the placement groove 101. Rotary gear shafts 1014 are connected to both sides of the placement groove 101 near the fitting groove 1013. A traction rope 1015 is connected to the middle of the rotating gear shaft 1014. A stop rod 2 is connected to both sides of the placement groove 101. One end of the stop rod 2 is connected to the rotating gear shaft 1014 through the traction rope 1015.

[0021] First, place the stirrup 1 onto the lower layer of steel bars on the floor slab to be poured. Then, place the upper layer of steel bars crisscrossingly onto the placement slots 101 of the stirrup 1. This not only separates the upper and lower layers of steel bars but also ensures the stability of the steel reinforcement frame during pouring.

[0022] Furthermore, the elastic layer 1011 is made of rubber, the fitting rod 1012 is a rod body that mates with the bottom of the elastic layer 1011 and the fitting groove 1013, one side of the rotating gear shaft 1014 protrudes from both sides of the fitting groove 1013, and the protruding part of the rotating gear shaft 1014 meshes with both sides of the fitting rod 1012. The rotating gear shaft 1014 also includes a winding shaft 1016, which is located in the middle of the rotating gear shaft 1014. The winding shaft 1016 is a round shaft with a diameter smaller than that of the rotating gear shaft 1014, and the traction rope 1015 is wound and connected to the surface of the winding shaft 1016.

[0023] When the reinforcing bar is placed on the placement groove 101, the weight of the reinforcing bar will apply pressure to the elastic layer 1011, forcing the elastic layer 1011 to deform and contract into the placement groove 101, so that the reinforcing bar can be placed into the placement groove 101. At the same time, when the elastic layer 1011 contracts and deforms, it will drive the bottom fitting rod 1012 to move into the fitting groove 1013. When the fitting rod 1012 moves, because its two sides are engaged with the rotating gear shaft 1014, the fitting rod 1012 will drive the rotating gear shaft 1014 to rotate when it moves down. When the rotating gear shaft 1014 rotates, it will rotate and collect the traction rope 1015 connected in the winding shaft 1016.

[0024] Furthermore, the abutment rod 2 also includes a hinge shaft 201. One end of the abutment rod 2 is connected to the hinge shaft 201. The abutment rod 2 is rotatably connected to both sides of the placement groove 101 through the hinge shaft 201. A torsion spring is provided at one end of the hinge shaft 201 that is rotatably connected to the placement groove 101. The hinge shaft 201 is wound and connected to the end of the traction rope 1015 away from the winding shaft 1016.

[0025] When the traction rope 1015 is taken in due to the rotation of the winding shaft 1016, it will pull the part wrapped around the hinge shaft 201, thereby causing the hinge shaft 201 to rotate. When the hinge shaft 201 rotates, it will cause the abutment rod 2 to deflect, thereby abutting against the steel bar in the placement groove 101. The two abutment rods 2 will clamp and abut against the steel bar to prevent it from easily swaying left and right after placement, which would cause it to be unstable and affect the pouring.

[0026] The following is a detailed implementation process of this utility model: First, the stirrup 1 is placed on the lower layer of reinforcing bars on the floor slab to be poured. Then, the upper layer of reinforcing bars is placed crisscrossingly into the placement slots 101 of the stirrup 1. This not only separates the upper and lower layers of reinforcing bars but also stabilizes the reinforcing bar frame. When the reinforcing bars are placed into the placement slots 101, the weight of the reinforcing bars applies pressure to the elastic layer 1011, forcing the elastic layer 1011 to deform and contract into the placement slots 101, allowing the reinforcing bars to be placed into the placement slots 101. Simultaneously, when the elastic layer 1011 contracts and deforms, it drives the bottom fitting rod 1012 to move into the fitting groove 1013. During displacement, because its two sides mesh with the rotating gear shaft 1014, the engaging rod 1012 will drive the rotating gear shaft 1014 to rotate when it moves downward. When the rotating gear shaft 1014 rotates, it will rotate and retract the traction rope 1015 connected in the winding shaft 1016. When the traction rope 1015 is retracted due to the rotation of the winding shaft 1016, it will pull the part wrapped around the hinge shaft 201, thereby driving the hinge shaft 201 to rotate. When the hinge shaft 201 rotates, it will drive the abutment rod 2 to deflect, thereby abutting against the steel bar in the placement groove 101. The two abutment rods 2 will clamp and abut against the steel bar to prevent it from easily swaying left and right after placement, which would cause it to be unstable and affect the pouring.
