[0002] Stirrups are structures used to support the reinforcing bars inside the mold, providing support for the steel frame structure within the mold.

[0003] In the process of constructing a disc-lock scaffold inside the mold box of the cast-in-place beam, the disc-lock scaffold is used to support the mold and prevent it from deforming under pressure when the concrete is poured. However, because the disc-lock scaffold needs to support the mold and separate it from the part to be poured at the bottom of the inner box, the existing support structure is cast together with the bottom part and cannot be removed. Utility Model Content

[0004] The purpose of this utility model is to provide a reusable cast-in-place beam support base stirrup device, which solves the problem that the bottom of the inner box disc buckle support structure is poured together with the concrete, resulting in the support structure being a one-time use and remaining in the concrete, which may eventually protrude from the concrete surface.

[0005] This utility model is achieved through the following technical solution: This utility model provides a reusable cast-in-place beam support base stirrup device, including a box formwork base plate, a connecting rod on the top of the box formwork base plate, a connecting sleeve connected to the top of the connecting rod, a supporting stirrup connected to the top of the connecting sleeve, a supporting steel bar on the middle side wall of the supporting stirrup, and abutment components connected to the top two sides of the supporting stirrup, the abutment components swinging along the axis.

[0006] Preferably, the bottom of the connecting rod is connected to the concrete at the top of the box formwork bottom plate.

[0007] Preferably, the inner wall of the connecting sleeve is threaded to the side wall of the top portion of the connecting rod.

[0008] Preferably, the supporting stirrup also includes a connecting thread, which is provided on the side wall of the bottom part of the supporting stirrup, and the connecting thread matches the thread on the inner wall of the connecting sleeve.

[0009] Preferably, the supporting reinforcing bars are arranged in three loops around the side wall of the supporting stirrups, and the top of the supporting reinforcing bars is curved.

[0010] Preferably, the abutment component includes a bonding block, a pin hole, a scale, and a pin. The bonding block is connected to the two sides of the support stirrup near the top, the pin hole is located on one side of the bonding block, the scale is located on one side of the bonding block, and the pin is connected to the two sides of the support stirrup near the top.

[0011] Preferably, the top of the bonding block is connected to the inner part of the supporting trestle near the top via a hinge shaft, and torsion springs are provided at both ends of the hinge shaft, and the bonding block is a triangular square.

[0012] Preferably, the supporting blocks on both sides near the top of the trestle are staggered and connected.

[0013] Preferably, the pin holes are arranged in a series of arcs.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects: 1. The supporting stirrups connected by the connecting sleeve can support the inner box disc buckle bracket, and can also be removed and reused.

[0015] 2. The device is also equipped with a backing component.

[0020] The following is combined with Figures 1 to 3 This utility model will be described in detail.

[0021] A reusable cast-in-place beam support base stirrup device includes a box formwork base plate 1, a connecting rod 2 is provided on the top of the box formwork base plate 1, a connecting sleeve 201 is connected to the top of the connecting rod 2, a supporting stirrup 3 is connected to the top of the connecting sleeve 201, a supporting steel bar 302 is provided on the middle side wall of the supporting stirrup 3, and abutment components are connected to the top two sides of the supporting stirrup 3, and the abutment components swing along the axis.

[0022] Furthermore, the bottom of the connecting rod 2 is connected to the concrete at the top of the box formwork base plate 1, the inner wall of the connecting sleeve 201 is threadedly matched with the top part of the side wall of the connecting rod 2, the supporting stirrup 3 also includes a connecting thread 301, the connecting thread 301 is provided on the bottom part of the side wall of the supporting stirrup 3, the connecting thread 301 is threadedly matched with the inner wall of the connecting sleeve 201, and the supporting steel bar 302 is arranged in three loops on the side wall of the supporting stirrup 3, the top of the supporting steel bar 302 is curved.

[0023] First, the bottom slab reinforcement is erected in the formwork of the cast-in-place beam. Then, the bottom concrete is poured first, and connecting rod 2 is welded into the bottom slab reinforcement. The bottom part of the connecting rod 2 is then poured together with the concrete to fix the connecting rod 2. Then, a connecting sleeve 201 is set on the top of the connecting rod 2. The thread on the inner wall of the connecting sleeve 201 is used to connect with the connecting thread 301 at the bottom of the supporting stirrup 3, so that the supporting stirrup 3 is stably connected to the top of the connecting rod 2. Then, when the inner box disc buckle bracket is erected in the casting formwork, the bottom steel pipe of the disc buckle bracket can be directly sleeved onto the top of the supporting stirrup 3 and then abutted against the supporting reinforcement 302. The arc bending of the supporting reinforcement 302 forms a platform to support the bottom steel pipe of the disc buckle bracket, thus completing the support of the disc buckle bracket. Since the supporting stirrup 3 is threaded to the connecting rod 2, the supporting stirrup 3 will not be disconnected from the cast part. After the casting is completed and the disc buckle bracket is removed, the entire supporting stirrup 3 can also be removed and reused.

[0024] Furthermore, the abutment component includes a bonding block 303, a pin hole 3031, a scale 3032, and a pin 304. The bonding block 303 is connected to the two sides of the support spur 3 near the top. The pin hole 3031 is located on one side of the bonding block 303, the scale 3032 is located on one side of the bonding block 303, and the pin 304 is connected to the two sides of the support spur 3 near the top. The top of the bonding block 303 is connected to the inside of the support spur 3 near the top via a hinge shaft. Both ends of the hinge shaft are provided with torsion springs. The bonding block 303 is a triangular block. The bonding blocks 303 on the two sides of the support spur 3 near the top are staggered. The pin holes 3031 are arranged in several arcs.

[0025] Meanwhile, when the bottom steel pipe of the disc buckle bracket is fitted onto the supporting steel bar 302, the pin 304 on the supporting steel bar 302 can be removed by controlling it. Then, by applying force to the protruding fitting blocks 303 on both sides, the fitting blocks 303 are deflected and contracted along the hinge axis at one end, thereby controlling the protruding area of ​​the fitting blocks 303 to adapt to the inner diameter of the bottom steel pipe of the disc buckle bracket of different sizes. Then, it is fixed by the pin 304. At the same time, the triangular shape of the fitting blocks 303 makes the sides inclined, which also corrects the bottom steel pipe of the disc buckle bracket when it is fitted, so that it can keep the connection with the steel pipe centered when adapting to steel pipes of different sizes, and prevent the steel pipe from swaying or tilting because the diameter of the supporting steel bar 302 is smaller than the inner diameter of the steel pipe.

[0026] Finally, because the two bonding blocks 303 on both sides are offset to the left and right, the two bonding blocks 303 will not come into contact with each other when they deflect and shrink, which makes it impossible to continue to deflect and shrink.

[0027] The following is a detailed implementation process of this utility model: First, the bottom plate reinforcement is built in the mold of the cast-in-place beam. Then, the bottom concrete is poured first, and the connecting rod 2 is welded into the bottom plate reinforcement. Then, the bottom part of the connecting rod 2 is poured together with the poured concrete to fix the connecting rod 2. Then, a connecting sleeve 201 is set on the top of the connecting rod 2. The thread on the inner wall of the connecting sleeve 201 is used to connect with the connecting thread 301 at the bottom of the supporting stirrup 3, so that the supporting stirrup 3 is stably connected to the top of the connecting rod 2. Then, when the inner box disc buckle bracket is built in the casting mold, the bottom steel pipe of the disc buckle bracket can be directly sleeved onto the top of the supporting stirrup 3 and then abutted against the supporting reinforcement 302. The arc bending of the supporting reinforcement 302 forms a platform to support the bottom steel pipe of the disc buckle bracket, thus completing the support of the disc buckle bracket. Since the supporting stirrup 3 is threaded to the connecting rod 2, after the disc buckle bracket is removed after the casting is completed, the entire supporting stirrup 3 can also be removed and reused.

[0028] Meanwhile, when the bottom steel pipe of the disc buckle bracket is fitted onto the supporting steel bar 302, the pin 304 on the supporting steel bar 302 can be removed by controlling it. Then, by applying force to the protruding fitting blocks 303 on both sides, the fitting blocks 303 are deflected and contracted along the hinge axis at one end, thereby controlling the protruding area of ​​the fitting blocks 303 to adapt to the inner diameter of the bottom steel pipe of the disc buckle bracket of different sizes. Then, it is fixed by the pin 304. At the same time, the triangular shape of the fitting blocks 303 makes the sides inclined, which also corrects the bottom steel pipe of the disc buckle bracket when it is fitted, so that it can keep the connection with the steel pipe centered when adapting to steel pipes of different sizes, and prevent the steel pipe from swaying or tilting because the diameter of the supporting steel bar 302 is smaller than the inner diameter of the steel pipe.
