Double-skin wall with lifting hook

Technical Field

The utility model relates to the technical field of integral buildings, in particular to a double-skin wall with a lifting hook.

Background

Double-skin walls are widely used in the residential and industrial construction fields, and mainly build integral buildings together with laminated slabs, which are lighter in weight than solid walls. This also makes it possible to install the semifinished products on the site with cranes of lower bearing capacity. Furthermore, the transportation cost of transporting double skin walls to a construction site is lower compared to solid concrete prefabricated elements. The double-skin wall comprises two concrete skins arranged at intervals, a steel bar framework is embedded in each skin, and the two steel bar frameworks are connected through truss ribs. The two outer sides of the double-skin wall are as flat as the template. Because of the high surface quality, both sides of the wall can be decorated or painted immediately.

As shown in fig. 1, the present embodiment discloses a double-skin wall with hooks, which comprises two concrete skins, a framework structure and a plurality of hooks 1.

Two concrete wallboards set up at the interval, and through concrete placement shaping. The framework structure includes two steel reinforcement frameworks 10 that the interval set up and the truss muscle (not shown in the figure) of connecting two steel reinforcement frameworks 10, and two steel reinforcement frameworks 10 bury in two concrete walling respectively in advance, and steel reinforcement framework 10 is formed by the steel reinforcement welding of crossing anyhow.

Lifting hook 1's shape is the U type, and a plurality of lifting hooks 1 set up along the length direction interval of double skin wall, and lifting hook 1 is located framework 10's top, and is located between two framework 10. The arc portion 11 of lifting hook 1 is located the top, and two landing legs 12 of lifting hook 1 are fixed in respectively on two framework of steel reinforcement 10, and two landing legs 12 are pre-buried in two concrete walling respectively.

Landing leg 12 ligature is carried out prepositioning on framework 10, then makes landing leg 12 be connected with framework 10 through the welding again, and the welding can make landing leg 12 and framework 10 become a whole, makes and can not produce the displacement between the two, guarantees not to damage the concrete wall skin.

The bottom of landing leg 12 is provided with kink 121, can increase the lifting surface area of landing leg 12, makes it not fragile concrete wall skin.

Be provided with splice bar 13 on lifting hook 1, specifically, the top of two landing legs 12 is connected with splice bar 13, and the bottom of two landing legs 12 is passed through splice bar 13 and is connected, and splice bar 13 and landing leg 12 welded connection. The connecting rib 13 at the top mainly plays a supporting role, and the lifting hook 1 is prevented from deforming in the lifting process to damage the concrete wall skin. The main body part of the lifting hook 1 is formed by bending thicker steel bars, specifically HPB300 steel bars, and then the connecting bars 13 are welded. The welding requirement of the lifting hook 1 in the welding process of welding the connecting rib 13 and the steel reinforcement framework 10 is as follows: the welding current cannot be too large, so that meat biting is prevented; slag inclusion is prevented; the welding slag formed by welding needs to be knocked off. The length of the legs 12 is not less than 30D, where D is the diameter of the rebar used in the hook 1.

Owing to set up lifting hook 1, need not hook truss muscle at the in-process of lifting by crane double skin wall, but hook lifting hook 1, because lifting hook 1 and framework 10 fixed connection, can make framework 10 whole atress at the in-process of lifting by crane, but local atress can guarantee that lifting hook 1, truss muscle and framework 10 can not take place to warp to guarantee that the concrete wall skin is not damaged.

It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
