Detailed Description
For better understanding of the present invention, the technical solution of the present invention will be further described below with reference to the following embodiments and accompanying drawings.
As shown in figure 1, a novel turnover load-bearing anchoring device comprises a sleeve 2 and a striking rod 1.
As shown in fig. 2, 3 and 4, the lower cylinder wall of the sleeve 2 is uniformly divided into a plurality of expansion pieces 4, and the expansion pieces 4 are wedge-shaped with a thin upper part and a thick lower part; the upper end of the sleeve 2 is provided with an end head part 5 with the diameter larger than that of the sleeve 2, a limiting hole 7 coaxially communicated with the inner cavity of the sleeve 2 is arranged in the end head part 5, and the diameter of the limiting hole 7 is larger than the inner diameter of the sleeve 2; the lower edge of the end head part 5 is provided with an rabbet part 6. The sleeve 2 and the end head part 5 are integrally formed and made of elastic steel (such as spring steel), so that the expansion sheet 4 can rebound conveniently.
As shown in fig. 5, the striking rod 1 includes a rod body 9 inserted into the sleeve 2, and the lower end of the rod body 9 is used for spreading a plurality of expansion pieces 4. The lower part of the rod body 9 corresponding to the expansion sheet 4 is a tapered part 13 with a thick upper part and a thin lower part. The diameter of the rod body 9 is smaller than the inner diameter of the upper part of the sleeve 2 (slightly smaller clearance fit), (the conical part 13) and is larger than the inner diameter of the lower expansion sheet 4 of the sleeve 2. The upper end of the rod body 9 is provided with a limiting part 10 and a rod head 11 in sequence, the diameter of the limiting part 10 is matched with that of the limiting hole 7, the diameter of the rod head 11 is larger than that of the limiting hole 7, and the length of the limiting part 10 is larger than the depth of the limiting hole 7.
Lubricating oil is coated on the conical part 13 and/or the expansion sheet 4.
The side wall of the end head part 5 is provided with a round hole 8, and the position corresponding to the limiting part 10 is provided with a waist-shaped hole 12 which is axially arranged; when the striking rod 1 is completely inserted into the sleeve 2, the pulling-out of the striking rod 1 is restricted by inserting a pin 3 into both the circular hole 8 and the kidney-shaped hole 12.
As shown in fig. 7, 8 and 9, the utility model is used as follows:
(1) aligning the hole of the connecting piece 15 with the reserved hole on the concrete surface, and inserting the sleeve 2 into the hole of the connecting piece and the reserved hole of the concrete; the diameter of the hole opening is 2-3 mm larger than the outer diameter of the sleeve 2, and the hole can be communicated or not communicated (when the hole is not communicated, the depth of the hole is 5-10 mm larger than the maximum installation depth of the sleeve 2).
(2) The impact rod 1 is inserted and the upper part of the impact rod 1 is hammered, the lower end of the impact rod 1 extrudes the inner wall of the lower part of the sleeve 2 to force the expansion sheet 4 to expand, and the outer wall of the expansion sheet 4 props against the hole wall of the concrete and is fixedly connected with the concrete.
(3) After the stroke of the striking rod 1 is in place, the limiting part 10 is abutted against the bottom of the limiting hole 7, and a certain distance is reserved between the rod head 11 and the end head part 5; the bolt 3 is inserted into the round hole 8 and the waist-shaped hole 12, and the striking rod 1 and the sleeve 2 are locked to ensure that the striking rod 1 does not slide.
(4) After the connection and fixation and the use of the bearing point are finished, the bolt 3 is firstly pulled out, and then the striking rod 1 (the gap between the rod head 11 and the end head part 5) is pried upwards by the crow bar 14, so that the striking rod 1 is forced to move reversely, and the bottom of the striking rod 1 moves upwards and is pulled out. The expansion sheet 4 at the lower part of the sleeve 2 recovers a cylindrical shape due to the elastic rebound of the expansion sheet.
(5) After the impact rod 1 is pulled out, the expansion sheet 4 at the lower part of the sleeve 2 is restored due to the self elastic resilience, and a gap is formed between the sleeve 2 and the concrete hole. And then the crowbar 14 is used for prying the sleeve 2 from the rabbet part 6, the sleeve 2 is taken out of the hole, and the connecting piece 15 is detached.
And (5) repeating the steps (1) to (5) to realize turnover use.
The above description is only an example of the present invention, and certainly, the scope of the present invention should not be limited thereto, and therefore, the present invention is not limited to the above description.
