Technical Field

The utility model belongs to the technical field of pre-buried hoist and mount piece, especially, relate to a pre-buried hoist and mount piece of concrete member.

Background

Concrete components, i.e. products of concrete components that are prefabricated for on-site assembly, are nowadays more and more prefabricated rather than on-site in the construction field due to the many advantages of prefabricated components. Compared with on-site manufacturing (generally in-situ casting), the prefabricated part is manufactured in a production workshop and then transported to a construction site for use, so that the processes of demolding, transferring, hoisting and the like are added.

In order to conveniently hoist and transport the concrete member, the hoisting piece is generally embedded in the concrete member, and the hoisting point exposed out of the member is cut and removed after the hoisting construction is finished. However, if the friction force on the surface of the embedded hoisting piece is not enough to bear the weight of the whole concrete member, the embedded hoisting piece is easily pulled out in the hoisting process of the concrete member. Therefore, how to design the structure of the embedded hoisting piece to improve the anti-pulling capacity of the embedded hoisting piece is a technical problem to be solved urgently in the industry.

Detailed Description

The principles and features of the present invention will be described with reference to the drawings, which are provided for illustration only and are not intended to limit the scope of the invention.

In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, only for convenience of description and simplification of description, but not for indicating or implying that the referred device or element must have a specific orientation and a specific orientation configuration and operation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1-5, the embodiment of the utility model provides a pre-buried hoist and mount piece of concrete member, including hoist and mount barrel 1 and base 3, a terminal surface (specifically for the rear end face) of hoist and mount barrel 1 and base 3 welded fastening are integrated into one piece for whole pre-buried hoist and mount piece is firm more stable. The hoisting cylinder body 1 is cylindrical, the inner circular hole of the hoisting cylinder body 1 penetrates through the base 3, and the hoisting cylinder body 1 is integrally of a cylindrical structure, so that compared with the existing cylindrical and conical cylindrical combined structure, the production process is simpler, and the production cost is lower. An internal thread 4 is arranged on the inner wall of one end, far away from the base 3, of the hoisting barrel body 1, the internal thread 4 is used for being connected with a hoisting point of hoisting equipment, and the internal thread 4 is connected with the hoisting equipment conveniently and quickly through threads.

As shown in fig. 1 to 5, a plurality of external convex strips 2 are axially arranged outside the hoisting barrel 1, the external convex strips 2 are parallel to each other, and the external convex strips 2 are equiangularly arranged by using the central axis of the hoisting barrel 1 as the center. The cross section of the external convex strip 2 can be in a rectangular, long circular arc shape and other structures. The length of the outer convex strip 2 is 1/3-1/2 of the length of the hoisting cylinder body 1 (in the embodiment, the length of the outer convex strip 2 is 1/2 of the length of the hoisting cylinder body 1), so that sufficient friction force and wrapping force between the outer surface of the embedded hoisting piece and concrete can be ensured when the concrete member is hoisted, the anti-pulling performance of the embedded hoisting piece is enhanced, the binding force between the embedded hoisting piece and the concrete member is stronger, and the stability of the concrete member during hoisting can be greatly improved.

As shown in fig. 1 to 5, in this embodiment, four reinforcing ribs 5 are connected between the base 3 and the hoisting cylinder 1, the reinforcing ribs 5 are located outside the hoisting cylinder 1, the reinforcing ribs 5 are circumferentially arrayed around the central axis of the hoisting cylinder 1, and the reinforcing ribs 5 can improve the structural strength between the base 3 and the hoisting cylinder 1, thereby preventing the base 3 from being separated from the hoisting cylinder 1 during the hoisting process. Further, outer sand grip 2 is close to and contacts between base 3's one end and the base 3, and formula welded structure as an organic whole, like this, the contact point between outer sand grip 2 and the base 3 also can be understood as the strengthening rib structure, like this, has further improved the structural strength of pre-buried hoist and mount piece, has guaranteed that base 3 can not break away from with hoist and mount barrel 1 when hoist. In the present embodiment, the base 3 is in a diamond shape (of course, other polygonal structures such as a circle and a square may be adopted), and rounded corners are provided at four corners of the base 3.

In this embodiment, through 4 threaded connection with the internal thread of outside hoisting point and 1 inner wall of hoist and mount barrel during hoist and mount, lift by crane, because many outer sand grips 2 of pre-buried hoist and mount piece surface can increase its and the concrete between frictional force to the anti pull-out performance of pre-buried hoist and mount piece is strengthened, and the cohesion that makes between pre-buried hoist and mount piece and the concrete member is stronger, stability when can improve the concrete member hoist and mount greatly.
