Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of pre -buried screw rod of steel plant, and specifically relates to a pre -buried screw rod anti -break connection structure for steel plant. BACKGROUND

[0002] The support pre -buried screw rod is a kind of fixing mode commonly used in the installation of steel plant equipment, is widely used in the installation of speed reducer, motor and other frame structure. By pre -buried screw rod when pouring concrete, it can provide stable and reliable installation foundation for subsequent equipment. This mode not only has strong bearing capacity, but also can effectively disperse the load and vibration of equipment operation, guarantee the stable operation of equipment. Especially in the complex production environment of steel plant, pre -buried screw rod provides efficient and economic solution for equipment fixation.

[0003] However, in actual application, due to operation error or other uncontrollable factors, pre -buried screw rod can break, once the screw rod breaks, the traditional repair method usually needs to knock off the surrounding concrete and re -buries the screw rod, this operation not only needs to consume a lot of time and manpower, but also can cause damage to the overall structure of pouring platform. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing a pre -buried screw rod anti -break connection structure for steel plant to solve at least one aspect of the problems and defects proposed in the above background technology.

[0007] Further, the support rib plate is arranged between the pre -buried sleeve and pouring platform, and the support rib plate is designed by transverse or inclined reinforcing rib, so that the vertical load and lateral force borne by the pre -buried sleeve are dispersed to a larger concrete area, and stress concentration is reduced. The support rib plate is closely combined with the pouring platform, the stress area of the pre -buried sleeve is increased, and the anchoring of the pre -buried sleeve and the concrete is more stable.

[0008] Further, the outer wall of the pre -buried sleeve is provided with a plurality of ring-shaped reinforcing ribs, the ring-shaped reinforcing ribs increase the surface area of the pre -buried sleeve in contact with the concrete, so that external forces can be more evenly dispersed to the surrounding concrete, and stress concentration is reduced in a single position.

[0009] Furthermore, the connecting sleeve has a first mounting part and a second mounting part respectively provided on its upper and lower sides. A connecting screw and a repair screw are respectively snapped onto the first mounting part and the second mounting part. The first mounting part and the second mounting part serve as the fixing positions for the connecting screw and the repair screw, respectively. The snap-fit ​​method enables quick assembly and disassembly, which is convenient for replacement and maintenance. The connecting sleeve can be reused, and only the damaged screw parts need to be replaced, thus reducing maintenance costs.

[0010] Furthermore, the upper part of the connecting screw is provided with a first conical connecting portion, which engages within the first mounting portion. The design utilizes a 45° conical angle to achieve self-locking, leveraging a wedge effect. When an external force is applied, the conical surface generates radial and axial forces, which enhance the tightness of the connection and prevent loosening. The conical structure facilitates insertion and removal, enabling quick installation and disassembly of the screw and simplifying maintenance.

[0011] Furthermore, the bottom of the repair screw is provided with a second conical connecting part, which engages within the second mounting part. This second conical connecting part is also a 45° cone, achieving self-locking through the 45° cone angle. When an external force is applied, the conical surface generates radial and axial components of force, which enhances the tightness of the connection and prevents loosening. The conical structure facilitates insertion and removal, enabling quick installation and disassembly of the screw and simplifying the maintenance process.

[0012] Furthermore, reinforcing rings are provided on both the upper and lower sides of the connecting sleeve. The reinforcing rings wrap around the upper and lower ends of the connecting sleeve through a ring structure, enhancing the rigidity and strength of the sleeve ends and preventing deformation, cracking, or failure caused by external forces. The reinforcing rings form an additional protective layer at the upper and lower ends of the connecting sleeve, preventing direct damage to the sleeve ends from the external environment (such as impact, corrosion, etc.).

[0013] Furthermore, the bottom of the connecting screw is provided with a first threaded connection part, which is threaded into the pre-embedded sleeve. The threaded connection utilizes the friction and mechanical locking characteristics of the helical groove to firmly fix the connecting screw in the pre-embedded sleeve. The threaded connection is detachable, facilitating quick replacement of the connecting screw when needed without damaging the concrete or the pre-embedded sleeve. Only the connecting screw needs to be replaced, without extensive disassembly or reconstruction, thus shortening maintenance time.

[0014] Furthermore, the upper part of the repair screw is also provided with a second threaded connection part. The second threaded connection part engages with the threaded hole on the motor base or equipment base to achieve a firm mechanical connection. The threaded connection facilitates the quick installation and disassembly of the equipment base, improving the efficiency of maintenance and replacement.

[0015] The utility model discloses the beneficial effect:

[0016] The embedded sleeve is fixed through the thread with the connecting screw rod, the connecting screw rod is connected with the repair screw rod through the connecting sleeve, so that the connecting screw rod and the repair screw rod become independent components, can be replaced or repaired individually, avoid the integral structure damage, the connecting screw rod and the embedded sleeve adopt the thread connection, can dismantle the damaged part and replace the new screw rod after breaking, the repair screw rod is connected with the connecting screw rod through the connecting sleeve, and the connecting sleeve can also be used as the extension or repair component, further enhance the flexibility. The connecting screw rod and the repair screw rod can be directly dismantled and replaced, avoid the concrete chiseling and re-pouring caused by breaking, reduce the repair time. Damaged screw rod or sleeve can be replaced individually, reduce the maintenance cost, prolong the service life of the integral structure. After breaking, the concrete does not need to be destroyed, and can be directly replaced or welded repair. BRIEF DESCRIPTION OF DRAWINGS
