Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated beam notch reinforcement, in particular to a prefabricated beam notch reinforcement structure. Background Art

[0002] Precast beam notch refers to a rectangular or other shaped hole formed at the mid-span or support of a concrete beam due to structural requirements or cutting. Precast beam notches are usually reserved when the beam is produced to facilitate installation and connection. In order to ensure the structural integrity and bearing capacity of the notch on the precast beam, a reinforcement structure is required to reinforce the notch.

[0003] Existing prefabricated beam notch reinforcement structures usually weld prefabricated reinforcement plates to the notch area of ​​the prefabricated beam. However, after being subjected to cyclic loads for a long time, fatigue cracks may appear in the welded joints between the reinforcement plates and the notch, which may lead to a reduction in the strength of the reinforced structure, thereby reducing the reinforcement effect on the prefabricated beam notch.

[0004] Therefore, a prefabricated beam notch reinforcement structure is proposed to solve the above problems. Utility Model Content

[0007] Preferably, the fixing assembly includes a driving disk rotatably connected to the inner wall of the reinforcing rod, the top of the driving disk is provided with an annularly distributed driving hole, the top of the mounting block is fixedly connected to the driving rod, the surface of the driving rod is slidably connected to the inner wall of the driving hole, and the top of the driving disk is fixedly connected to a turntable, and the rotation of the turntable drives the three mounting blocks to move simultaneously through the driving disk, the driving hole and the driving rod, so that they are snapped into the mounting groove, thereby reinforcing the notch of the prefabricated beam, and reinforcing the notch of the prefabricated beam is more convenient, avoiding the inconvenience of welding the reinforcement plate to the notch for reinforcement by welding, and ensuring the stability of the reinforcement rod on the notch of the prefabricated beam.

[0008] Preferably, the inner wall of the turntable is slidably connected to a fixing rod, the surface of the fixing rod is clamped on the inner wall of the reinforcement rod, and the fixing rod is clamped into the reinforcement rod through the turntable, thereby positioning the turntable to prevent the turntable from rotating under the action of vibration force, thereby improving the stability of the reinforcement rod on the notch of the prefabricated beam and ensuring the effect of the reinforcement structure on reinforcing the notch of the prefabricated beam.

[0009] Preferably, a movable hole is opened on the inner wall of the fixing rod, and the inner wall of the movable hole is slidably connected to a limiting block. The surface of the limiting block is clamped on the inner wall of the reinforcement rod. One side of the limiting block is fixedly connected with a spring, and one end of the spring is fixedly connected to one side of the inner wall of the movable hole. The elastic force of the spring pushes the limiting block to move and clamp into the reinforcement rod, thereby locking the fixing rod on the reinforcement rod, making the locking turntable more stable, and improving the stability of the reinforcement rod in the mounting hole.

[0010] Preferably, an anti-skid groove is provided on the surface of the mounting block, and the inner wall of the anti-skid groove is engaged with the inner wall of the bridge; a positioning groove is provided on one side of the limit block, and the inner wall of the positioning groove is engaged with the inner wall of the reinforcement rod; because the surfaces of the anti-skid groove and the positioning groove are both in the shape of a dovetail groove, the anti-skid groove is used to increase the contact area when the mounting block is connected to the mounting groove, provide more contact friction and anti-slip ability, and improve the stability of the mounting block when connected to the bridge; the positioning groove is used to increase the contact area when the limit block is connected to the reinforcement rod, and improve the stability of the limit block when connected to the reinforcement rod.

[0011] Preferably, the top of the limit block is fixedly connected to a driven block, the surface of the driven block is slidably connected to the inner wall of the movable hole, the top of the driven block is fixedly connected to an active block, the surface of the active block covers the movable hole, thereby blocking impurities from entering the movable hole, the active block and the driven block are used to drive the limit block to move into the movable hole, ensuring that the fixed rod can be easily moved in the turntable and the reinforcement rod.

[0012] The beneficial effects of the utility model are:

[0013] 1. The reinforcement rod is clamped into the installation hole to be reinforced, and the turntable is rotated. The rotation of the turntable drives the three installation blocks to move and clamp into the corresponding installation grooves through the driving plate, the driving hole and the driving rod, so as to reinforce the prefabricated beam gap. It is more convenient to reinforce the prefabricated beam gap, avoiding the inconvenience of welding the reinforcement plate to the gap for reinforcement by welding. The fixing rod is pushed, and the fixing rod moves in the turntable and is clamped into the reinforcement rod. The elastic force of the spring pushes the limit block to be clamped into the reinforcement rod, so that the fixing rod is locked in the reinforcement rod, thereby improving the stability of the installation block clamped into the installation groove, and improving the stability of the reinforcement rod on the prefabricated beam gap, avoiding the reinforcement rod from loosening in the installation hole under the action of cyclic load, and ensuring the effect of the reinforcement structure on reinforcing the prefabricated beam gap;

[0014] 2. Since the surfaces of the anti-skid groove and the positioning groove are both in the shape of a dovetail groove, the anti-skid groove is used to increase the contact area between the mounting block and the mounting groove, provide more contact friction and anti-slip ability, and improve the stability of the mounting block when it is connected to the bridge. The positioning groove is used to increase the contact area between the limit block and the reinforcement rod, and improve the stability of the limit block when it is connected to the reinforcement rod.
