Detailed Description

As shown in fig. 1 to 4, a precast concrete member hook sheath includes a first sheath body 1 and a second sheath body 2, wherein the first sheath body 1 and the second sheath body 2 are respectively provided with a magnet piece capable of attracting each other, and the magnet pieces are precast into the first sheath body 1 and the second sheath body 2 in advance. The first sheath body 1 and the second sheath body 2 can be spliced into a whole by magnetic attraction of the magnet pieces, and a positioning hole 4 for positioning the hook 3 is formed between the first sheath body 1 and the second sheath body 2. Under the effect of magnet piece, can connect into whole the use with first sheath main part 1 and second sheath main part 2, still be convenient for simultaneously establish first sheath main part 1 and second sheath main part 2 cover on lifting hook 3 and dismantle first sheath main part 1 and second sheath main part 2 after concrete placement is accomplished.

The magnet piece includes fixed protrusion 5 and recess 6, and fixed protrusion 5 is the iron mold insert or other materials that can be attracted by magnet, is equipped with the magnet mold insert in the recess 6, and fixed protrusion 5 and recess 6 are through the magnetic force zonulae occludens of attracting each other, connect first sheath main part 1 and second sheath main part 2 as an organic whole from this.

Preferably, the fixing protrusion 5 is a hemispherical protrusion, and the groove 6 is a hemispherical groove 6 matched with the fixing protrusion, so that the fixing protrusion and the groove can slide with each other conveniently, and the first sheath body 1 and the second sheath body 2 can be taken out after pouring. And one side of first sheath main part 1 and the concatenation of second sheath main part 2 is equipped with fixed arch 5 and recess 6 simultaneously, and second sheath main part 2 is the same with the structure of first sheath main part 1, and both are as the form shown in fig. 2 in this embodiment, when splicing, only need with both be provided with fixed arch 5 and recess 6 the side butt joint can be connected closely, convenient operation has also saved the cost of preparation sheath main part simultaneously.

The first sheath body 1 and the second sheath body 2 are provided with a pulling portion 13 that can be pulled. In a preferred embodiment, the pulling portion 13 is a pulling through hole, one pulling through hole is respectively arranged on the first sheath body 1 and the second sheath body 2, and after concrete pouring is completed, the first sheath body 1 and the second sheath body 2 are respectively taken out from two directions through the two pulling through holes, so that the detachment is facilitated.

The traditional lifting hook sheath is of an integrated structure and is not provided with a magnet piece. At the in-process to lifting hook sheath reuse, can pass the lifting hook sheath many times when different lifting hooks 3 business turn over locating hole 4 inside, this just makes the lifting hook sheath frequently receive the outside power on the width direction, causes the lifting hook sheath to warp easily in the past this long time to lead to can get into too much concrete in the lifting hook sheath in precast concrete member manufacture process, influence 3 inside formation of hanging the space of lifting hook, need the manual work to knock off the concrete in the lifting hook sheath moreover, waste time and energy. This embodiment is through setting up the magnet piece of inter attraction in first sheath main part 1 and second sheath main part 2, and the lifting hook sheath concatenation is a whole when can guaranteeing concreting, prevents that the concrete from getting into the lifting hook sheath and influencing 3 shapes of lifting hook, can correct the lifting hook sheath to the state of being close initial shape, has avoided the production of above-mentioned problem, has prolonged the life of lifting hook sheath.

In another embodiment, as shown in fig. 7 to 9, the magnet member includes at least two magnet blocks 7 that are attracted to each other, the two magnet blocks 7 are respectively disposed in the first sheath body 1 and the second sheath body 2, and the first sheath body 1 and the second sheath body 2 can be attracted and fixed by the magnet blocks 7. Be equipped with the mounting hole 8 that is used for installing magnet piece 7 in first sheath main part 1 and the second sheath main part 2, the inside of first sheath main part 1 and second sheath main part 2 is put into through mounting hole 8 to magnet piece 7, and the installation of magnet piece 7 is fixed to the completion to the shutoff of reuse rubber piece outside mounting hole 8. The first sheath main body 1 is provided with a transverse positioning strip 10 and a longitudinal positioning strip 11 which are perpendicular to each other, the cross sections of the transverse positioning strip 10 and the longitudinal positioning strip 11 are semicircular, and the second sheath main body 2 is provided with a positioning groove 12 matched with the transverse positioning strip 10 and the longitudinal positioning strip 11. Through the positioning of the transverse positioning strip 10 and the longitudinal positioning strip 11 and the positioning groove 12, the accurate positioning of the first sheath main body 1 and the second sheath main body 2 in the transverse direction and the longitudinal direction can be ensured, the sheath main bodies can be quickly combined into a whole, and the relative movement of the first sheath main body 1 and the second sheath main body 2 in the transverse direction and the longitudinal direction is avoided.

As shown in fig. 11, the magnet block 7 is preferably fixed in the first and second sheathing bodies 1 and 2 by bolts 9 for easy attachment and detachment. Note that the mounting method of the magnet block 7 is not limited to the above-described method, and any other method that can ensure stable mounting of the magnet block 7 can be applied.

Precast concrete member lifting hook sheath is made by rubber in this embodiment, in the actual production process, all can do the fillet to each reentrant corner and external corner department as required and handle, takes out the lifting hook sheath after being convenient for pour.

As shown in fig. 5, 6 and 10, in the process of manufacturing the precast concrete member, the arc-shaped portion of the hook 3 is aligned with the positioning hole 4, so that the first sheath body 1 and the second sheath body 2 can be spliced into a whole, the first sheath body 1 and the second sheath body 2 are positioned between adjacent steel bars, for a precast concrete pile, especially a precast concrete solid square pile, the precast concrete pile can be positioned between adjacent stirrups 14, and the first sheath body 1 and the second sheath body 2 are not in contact with the main bars, and concrete is poured. After the production is completed, the first sheath body 1 and the second sheath body 2 are pulled out of the concrete by hanging and pulling through holes by pulling tools such as a hook 3. The first sheath body 1 and the second sheath body 2 are respectively provided with a lifting through hole, and in the lifting process, component force to two sides of the lifting hook sheath is generated, so that the lifting hook sheath is more beneficial to being detached.

This embodiment adopts split type structure, is convenient for install and demolish the lifting hook sheath to through set up mated magnet piece 7 in first sheath main part 1 and second sheath main part 2, can make the lifting hook sheath keep the closure state, prevent that the condition of deformation from appearing in the lifting hook sheath. The embodiment can be repeatedly used for many times, has low cost and environmental protection, and is particularly suitable for precast concrete solid square piles.
