Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

Example one

Referring to fig. 1 and 2, the embodiment provides a pre-buried connecting member, which includes a sleeve 1 and a limiting disc 2, where the sleeve 1 and the limiting disc 2 are both of plastic structures, and certainly can be made of other polymer materials with certain structural strength.

The first improvement of the embedded connector of this embodiment lies in that the sleeve 1 is designed into a tubular structure with two open ends, wherein the outer wall of one end is connected with the limiting disc 2, which can be regarded as the limiting disc 2 having a hole in the middle, the limiting disc 2 is sleeved at one end of the sleeve 1 through the hole, and of course, the two are preferably integrally connected, i.e. integrally formed during processing, thereby ensuring the connection strength between the two.

Another improvement of the embedded connector in this embodiment is that a plurality of first reinforcing ribs (not shown in the figure) are arranged on the inner wall of the sleeve 1 along the circumferential direction thereof, and certainly, a plurality of first reinforcing ribs are arranged on the inner wall and the outer wall along the circumferential direction thereof.

As can be seen from the above description, the embedded connector of the present embodiment initially improves the structural strength thereof by the first reinforcing rib; and design the connecting piece into sleeve pipe 1 structure, can increase 9 spares of metal pole etc. in sleeve pipe 1 and further improve its structural strength, and then increased the connection stability of wall body and heated board, guaranteed the whole reliability of wall body.

Based on above-mentioned structure, this embodiment still makes further improvement to sleeve pipe 1 and spacing dish 2's structure, at first is to sleeve pipe 1's institutional advancement, as shown in fig. 1, this embodiment is equipped with a plurality of spacing barbs of its length direction interval distribution of edge at sleeve pipe 1 outer wall, and spacing barb sets up to 2 direction slopes of spacing dish, and spacing barb 3 is used for preventing that the built-in connecting piece from outwards shifting by oneself when non-artificial or pouring concrete.

In order to further improve the anti-displacement effect of the limiting barbs 3, two rows of limiting barbs 3 are respectively arranged on two opposite sides of the outer wall of the sleeve 1, and the two rows of limiting barbs 3 are symmetrically distributed about the axis of the sleeve 1.

And because the pre-buried connecting piece of this embodiment is used for connecting wall body and heated board, consequently need make further improvement to foretell spacing barb 3, so that it adapts to two kinds of different materials of wall body and heated board, make spacing barb 3 homoenergetic play good spacing effect in wall body and heated board respectively, consequently, this embodiment divide into adjacent first region 4 and second region 5 with sleeve pipe 1 along its length direction, first region 4 is close to spacing dish 2 and sets up, spacing dish 2 setting is kept away from to second region 5, wherein, spacing barb 3 that is located first region 4 is first contained angle with sleeve pipe 1 outer wall, spacing barb 3 that is located second region 5 is the second contained angle with sleeve pipe 1 outer wall, and first contained angle is greater than the second contained angle.

Specifically, the first included angle of the present embodiment is 55 ° to 65 °, and preferably 60 °; the second included angle of this embodiment is 40 ° -50 °, preferably 45 °, makes spacing barb 3 all can play good spacing effect in wall body and heated board respectively.

In addition, the outer wall of the sleeve 1 of the present embodiment is further provided with a plurality of ventilation holes 6, as can be seen from fig. 1, the upper portion and the lower portion of the sleeve 1 of the present embodiment are respectively provided with a plurality of ventilation holes 6, so that the interior of the sleeve 1 can be communicated with the outside, and the sleeve 1 is conveniently sleeved outside the metal rod 9.

This embodiment still improves spacing dish 2's structure, is equipped with a plurality of interval distribution's second strengthening rib 7 along its circumference on at least one terminal surface of spacing dish 2 to increase spacing dish 2's structural strength.

In addition, in this embodiment, at least one through hole 8 is further disposed between two adjacent second reinforcing ribs 7, because the wall is generally a cast-in-place structure, the through hole 8 is designed to facilitate the passage of wall material, and the through hole 8 is filled with the wall material, so that the structural strength of the limiting disc 2 can be further improved.

Example two

Combine fig. 3 and 4 to show, this embodiment provides a coupling assembling, including embodiment one pre-buried connecting piece and metal pole 9, the pre-buried connecting piece of this embodiment cup joints on metal pole 9, and both can be the cooperation of pegging graft, also can be through bonding material body coupling or plastics integrated into one piece, certainly also can be other connected modes, as long as can satisfy the design structure requirement can, this embodiment coupling assembling compare and have higher structural strength in current plastic connecting piece, and then improved wall body stability.
