Description

Technical Field

[0001] The utility model relates to the technical field of prestressed tendon connection, in particular to a prestressed tendon connection reinforcement device for building components. Background Art

[0002] Building components refer to the various elements that make up a building. If a building is regarded as a product, then building components refer to the parts of this product. Structural components are the elements that constitute the structural force skeleton, but they are generally divided according to the force characteristics of the components. They are divided into bending components, compression components, tension components, torsion components, compression-bending components, etc.

[0003] Prestressed steel bars are compressive stresses applied to the concrete of structural components by pre-tensioning or post-tensioning before the use of structural components. Tension is applied to the steel bars first, and then concrete is poured. When the strength reaches the required level, the steel bars are loosened to allow the steel bars to shrink and offset the tension of the normal use load (pre-tensioning method). Post-tensioning method is to pour concrete with reserved holes, add tensile steel bars after forming, and then anchor them at both ends of the component with equipment. When fixing it, the existing technology uses manual tightening of the two fixed screw rings. During the stress process, since the prestressed bars have been connected into a grid shape at this time, the workers are more laborious and time-consuming in the overall operation process and the operation is inconvenient.

[0004] Therefore, in view of the above problems, there is an urgent need for a convenient-to-use prestressed tendon connection and reinforcement device for building components. Utility Model Content

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] Embodiment: A building component prestressed tendon connection reinforcement device, such as Figure 2As shown, it includes a prestressed tendon 1, a U-shaped rod 2, a limiting plate 3 and a hexagonal spiral ring 4. The U-shaped rod 2 is sleeved below the intersection of the prestressed tendon 1. The U-shaped rod 2 is a double-layer U-shaped frame, and a notch is opened on the right side. The notch is separated at both ends, and the two ends are provided with threads adapted to the hexagonal spiral ring 4. The whole is a triangle that wraps the intersection of the prestressed tendon 1, which plays a role in stabilizing the position of the prestressed tendon 1. The left end of the U-shaped rod 2 sleeves the upper end of the prestressed tendon 1, so that the upper end is subjected to a counteracting force. The bottom of the U-shaped rod 2 is against the prestressed tendon 1, so that it is subjected to force up and down, and the prestressed tendon 1 is fixed. A limiting plate 3 is sleeved between the two ends of the right side of the U-shaped rod 2. The limiting plate 3 is used to limit the position between the notches at both ends of the U-shaped rod 2, so that the overall triangular area is more stable. The two ends of the U-shaped rod 2 above the limiting plate 3 are threaded with hexagonal screw rings 4. The hexagonal screw ring 4 is used to fix the position of the limiting plate 3, and then fix the U-shaped rod 2, and at the same time reinforce the prestressed tendon 1.

[0020] like Figure 1 and Figure 3 As shown, it also includes a mounting frame 5, a motor 6, a hexagonal collar 7 and a handle 8. A hexagonal collar 7 is sleeved on the top of the two hexagonal screw rings 4. The inner groove of the hexagonal collar 7 is adapted to the hexagonal screw ring 4, and a motor 6 is installed on the top of the two hexagonal collars 7. The output shaft of the motor 6 is connected thereto. The motor 6 is used to drive the hexagonal collar 7 to rotate, thereby completing the tightening of the hexagonal screw ring 4. A mounting frame 5 is fixedly arranged between the two motors 6. The mounting frame 5 is used to connect the positions of the two motors 6, so that the position of the driven hexagonal collar 7 when rotating is more fixed. A handle 8 is arranged in the middle of the right side of the mounting frame 5, and the handle 8 is used to hold the entire device.

[0021] like Figure 1 and Figure 3 As shown, it also includes a fixing rod 9, and the front and rear sides of the right part of the mounting frame 5 are fixedly provided with fixing rods 9; soft sponges 10, the bottom ends of the two fixing rods 9 are provided with soft sponges 10, the soft sponges 10 are in contact with the prestressed tendons 1, and the soft sponges 10 are in a resilient material, which is used to assist in fixing the position of the device as a whole; a limiting frame 11, a limiting frame 11 is provided on the left part of the mounting frame 5, and the lower part of the limiting frame 11 is frame-shaped, and the lower part of the limiting frame 11 can be covered with the prestressed tendons 1, so that the upper end of the prestressed tendons 1 is fixed; a limiting block 12, a limiting block 12 is provided at the lower side of the left part of the limiting frame 11, and the limiting block 12 is embedded in the inner side of the U-shaped rod 2, and the limiting block 12 is made of soft material and is in a resilient state, and has the function of limiting the force on the left side of the U-shaped rod 2; a fixing frame 13, a fixing frame 13 is provided between the mounting frame 5 and the lower side of the handle 8, which is used to assist in fixing the position between the motor 6 and the handle 8, so that the force point is better stabilized during use.

[0022] When the prestressed tendon 1 needs to be fixed, the staff first uses the handle 8 to cover the U-shaped rod 2 at the intersection of the prestressed tendon 1, so that the U-shaped rod 2 wraps the prestressed tendon 1 to form a triangular wrapping area, so that the prestressed tendon 1 is initially fixed, and then the right two ends of the U-shaped rod 2 are covered by the limiting plate 3, so that the position of the notch between the two ends is fixed, and then the hexagonal spiral ring 4 can be inserted into the two top ends of the U-shaped rod 2; at the same time, the soft sponge 10 is placed under the prestressed tendon 1 to support the bottom of the prestressed tendon 1 so that its force point is stabilized, and the soft sponge 10 has a rebound effect, so that the staff's force when being stressed is buffered, thereby achieving the effect of reducing force and buffering, and at the same time the limiting frame 11 fixes the upper end of the prestressed tendon 1 At this time, both the upper and lower ends have been fixed, and the limit block 12 is against the inner side of the U-shaped rod 2, so that the left side of the whole is fixed when the force is applied to avoid tilting and dislocation. Then the hexagonal screw ring 4 can be covered by the hexagonal ring 7, and then the motor 6 is started. Under the drive of the motor 6, the hexagonal ring 7 is rotated, thereby driving the hexagonal screw ring 4 to rotate and tighten, fixing the U-shaped rod 2 and also fixing the connection between the prestressed tendons 1. In this process, the staff needs to hold the handle 8, and hold the handle 8 so that the whole is in the above state. During the driving operation of the motor 6, the staff's hand also needs to be slightly stressed, and the fixing frame 13 stabilizes the position between the motor 6 and the handle 8, so that the overall use experience is more stable and reliable.
