Abstract

The utility model provides a pre -buried nut, includes nut head and screw rod, be equipped with the screw thread chamber in the screw rod, the screw thread chamber with be equipped with the edge between the nut head the round hole that the screw rod diameter runs through, be equipped with the internal thread in the round hole. By adopting the above technical scheme, this kind of pre -buried nut can let the reinforcing bar in the concrete pass the round hole to make the whole of pre -buried nut and concrete link as an organic wholeization, and screw rod surface annular thread set up the frictional force that has strengthened between pre -buried nut and the concrete, and then make self the ability of hanging and concrete the bearing capacity contact together, improved the ability of hanging of pre -buried nut greatly.

Description

A kind of Embeded nut

Technical field

The utility model relates to a kind of fixed block, is specifically related to a kind of Embeded nut.

Background technique

Usually need unsettled pendant part is installed in construction, furred ceiling, crane cable ventilation duct etc., past mostly to adopt in concrete pre-buried suspension hook or solves the method putting into setscrew after concrete product perforating with percussion drill, the shortcoming of these methods hangs pulling force deficiency, install complicated, and unsightly, for this reason, application number be 96220828.0 Chinese patent " concrete preburied nut " disclose a kind of concrete preburied nut, this nut establishes a hollow nut bar, a load pad is fixedly installed near this nut bar tail end, Nut pole tail end opening establishes the closeouts of this Nut pole tail end opening of a shutoff, a fixed block is established near the Nut pole the other end, fixed block comprises cylindrical part and is connected with this cylindrical part one end and the radially annular portion that formed of side, fixed block is located at Nut pole outside with cylindrical part and the close-fitting state of Nut pole.Although, this concrete embedded nut structure is simple, easy to manufacture, institute's consumption material is few, can be pre-buried in any direction, but the limited space be stuck in due to load pad in concrete, so cause the hanging capacity of embedded nut very limited, can not meet completely now construction industry to the requirement of huge hanging capacity.

Model utility content

For the deficiency that prior art exists, the purpose of this utility model is to provide that a kind of suspention ability is strong, frictional force large, make and be easy to a kind of Embeded nut.

For achieving the above object, the utility model provides following technological scheme: a kind of Embeded nut, comprises nut head and screw rod, is provided with thread cavity in described screw rod, be provided with the circular hole run through along described screw diameter between described thread cavity and described nut head, in described circular hole, be provided with internal thread.

By adopting technique scheme, this kind of Embeded nut is that the reinforcing bar in can allowing concrete passes circular hole, thus make embedded nut and concrete being connected as a single entity of entirety, and then the hanging capacity of self and concrete bearing capacity are linked together, substantially increase the hanging capacity of embedded nut.In addition, the circular hole run through along described screw diameter is provided with between described thread cavity and described nut head, such circular hole diameter can open maximum greatly, thus larger reinforcing bar can be allowed through circular hole, and the setting of screw thread enhances the fastness be connected between embedded nut with concrete reinforcement in circular hole, be conducive to the hanging capacity improving embedded nut further.

Of the present utility modelly to be set to further: described nut head is provided with vortex-like line, to increase the surface roughness of nut, be conducive to taking and installation of nut head.

Further scheme: described nut head is regular hexagon, thus be conducive to carrying out necessary operation by spanner to it, thus improve installation efficiency.

In figure: 1, nut head; 2, screw rod; 3, thread cavity; 4, circular hole; 5, rounded corners; 6, vortex-like line; 7, reinforcing bar, 8, internal thread.

Embodiment

Referring to figs. 1 through Fig. 4, the utility model embodiment is described further.

A kind of Embeded nut of the utility model, comprise nut head 1 and screw rod 2, be provided with thread cavity 3 in screw rod 2, the screw thread in thread cavity 3 arranges under clockwise direction, and be provided with between thread cavity 3 and nut head 1 along screw rod 2 diametric(al) and run through the circular hole 4 of screw rod 2.Then this kind of Embeded nut can be embedded in concrete by being run through by reinforcement in concrete 8 in advance, only exposes thread cavity 3, carry out suspension heavy weight by thread cavity 3.Because general reinforcing bar 8 is through full wafer concrete and as concrete support, thus the suspention ability of Embeded nut links together with concrete bearing capacity.And then substantially increase the suspention ability of embedded nut.In addition, circular hole 4 is opened on screw rod 2 along the diametric(al) of screw rod 2, so circular hole 4 can guarantee that embedded nut can normally in situation, screw rod 2 is offered the circular hole 4 of maximum diameter, to make thicker reinforcing bar 7 pass, thus to be conducive to the suspention ability improving embedded nut further.

Further scheme is: nut head 1 is provided with vortex-like line 6, increases the surface roughness of nut like this, workmen's taking and installation to it when being conducive to installing, thus prevents from slipping out of the hand dropping as far as possible.

Scheme is further again: nut head 1 is set to regular hexagon, as long as the position using common spanner just can be rotated by adjustment nut head 1 like this adjusts the position of thread cavity 3 times suspention article.

In addition, be also provided with internal thread 8 at circular hole 4 internal surface, be conducive to like this improving the frictional force between circular hole 4 and reinforcing bar 7, thus fixing and suspension heavy weight can play reasonable effect for installation.

Meanwhile, this embedded nut makes easy processing, and materials'use amount also compares province.

The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
