The invention relates to building construction, mainly to concrete panels, blocks and plates for various purposes, and may find applications in civil and industrial construction.

Known for reinforced concrete structures, such as floor panels, in which a supporting loop is then embedded in the concrete body of the panel (see "Standard design, products and units of buildings and structures". Series 1.141-1 "floor Panels prestressed concrete units". VIP. "Prestressed panel with a circular voids length 6280, 5980, 5680, 5080 and 4780 mm, width 1790, 1490, and 990 1190 mm, reinforced high-strength steel wire class BP-II. Developed a Central "Home" with the participation of NIIZHB, approved and put into effect with 15.04.86. Gosgrajdanstroy order No. 93 from 18.03.86 hell. 1.141-1.66.102). Similar slinging loops equipped with not only a concrete structure, but, for example, and concrete blocks for basement walls (see GOST 13579-78, p.14).

Famous concrete slabs, equipped with a closed slinging loops covering the reinforcing elements placed in the concrete slab (see "Typical building constructions, products and sites. Series 3.400-7 "Unified mounting loops for lifting precast concrete and concrete products". Issue 1/87, developed PI # 1 and NIIZHB, and approved by the construction Committee WITH THE CF 01.07.88, the Protocol from 03.03.88 No. AH-9, damn. 3.400-7.1/87-SM, 3.400-7.1/87-SM).

The main disadvantage of the described structures is a significant flow of metal on the device supporting loops.

Known lifting device for the manufacture and transportation of concrete and concrete products containing hollow body with a tapered base and the slots for the working bodies, pinned at him with accommodation for forming the housing, the gripping levers and latch operating position of the levers. Gripping levers supported along the entire length of the housing is spring-loaded and executed with the opportunity to interact with the latch operating position. The latch is wedge-shaped and is arranged to move along the vertical axis of the housing under the action of gravity and spring return (see C-ku on the invention of the Russian Federation No. 94020214, IPC6B66C 1/66, 1996).

The disadvantage of this solution is the complexity of the design, the necessity of using various additional materials, namely, rubber cone-shaped cover made with walls of variable thickness.

Known capture for concrete with a hole containing a hollow body with a bottom cylindrical part and the upper part is a guide for the lifting rod with a T-shaped gripping head (USSR Author's certificate is 981187, CL B66C 1/66, 1982).

The disadvantage of this device is the complexity of the design.

Known reinforced concrete structure comprising a concrete body and its armature, characterized in that it is provided with slinging holes through each of which passes the rod of the working valve with an estimated cross-sectional area (see RF patent №2241808, IPC7E04C 2/06, 2004).

The disadvantage of this device is the need to make holes on the valve and having sufficiently large dimensions to provide input under the valve supporting elements during installation and transportation. In addition, for the manufacture of these products should be kept strictly defined calculation section dimensions of the reinforcement that is not always economically feasible.

Known construction element, comprising a formed in the body of the concrete intersecting at an acute angle channels opening onto the top face of his and intended for fastening devices of the lifting and installation. One of the channels - vertical, larger diameter. The channels formed by seminolecounty in the body of concrete mortgage integral parts of the two tubes, the lower ends of which are plugged on the top has a removable tube, and on the sides of the tides with holes for fastening the reinforcing elements (see RF patent №2013507, IPC5 E04C 1/00, 1994). This decision was made as a prototype.

The disadvantage of the prototype is the complexity and inefficiency of the design, providing construction element receiving devices for lifting. This design does not provide a reliable engagement devices for lifting and as a result, is quite dangerous when moving to a height.

The problem solved by the invention is to simplify the construction, increase safety and productivity in the erection of buildings and structures.

The problem is solved due to the fact that in the known construction the element containing formed in the body of the concrete inclined channel extending at least one of the faces of the element, designed for fastening devices of the lifting and installation and educated by seminolecounty in the body of concrete fixtures, in accordance with the utility model, the channel is made with a thread on its surface.

The angle of the channel ranges from 30 to 45° to the transverse reinforcing rod at a construction element.

The construction element is configured to retrieve fixtures after its manufacture.

The technical result from the use of the utility model is to simplify the construction, increase safety and productivity in the erection of buildings and structures. The AOC is e, provided and considerable saving of metal.

Execution in the construction element of an inclined channel with a thread on its surface can simplify the design of the construction element and to improve safety and productivity in the erection of buildings and structures. This design allows to significantly improve the economy of metal in the manufacture of building elements.

The presence of the channel with the thread on the work surface allows you to voracity in a threaded hole studs and bolts, eyebolts, and delete data elements after installation of the construction element into place. Thread channel concrete building element as well as carving in metal, can carry the load and provide a reliable connection devices for lifting and installation (anchor bolt) with a construction element that allows the safe transportation of the construction element.

The construction element 1 (in the example, reinforced concrete wall panel) contains formed in the body of the concrete sloping channel 2, output, at least one of the faces 3 of the element, for example on the upper face (see figure 1, 2). Channel 2 is to be mounted in the construction element 1 devices 4 lifting and mounting (see Fig.7). Channel 2 is formed by seminolecounty in the body of concrete fixtures 5 (see figure 4). As fixtures 5 can be used, for example, a pin that allows you to perform channel 2, with carvings on its surface 6 (see figure 4).

The construction element is made in the usual way. Before pouring concrete into the form of a mortgage item 5 (hairpin with a continuous thread and end recesses under the socket wrench) is fixed to the valve using tie-wire 7 to 8 cross reinforcing rod rigidly connected with the longitudinal horizontal 9 and 10 vertical reinforcing steel rods (see figure 2, 4).

To prevent fracture of the upper part of the concrete building element and crumples thread in channel 2 when lifting and transporting, the pin 5 is set at an angle of ~90° to the reference axis of the mounting strap, which determines the angle of the channel in the range from 30 to 45° to the transverse reinforcing rod at a construction element.

After pouring, curing and removal of the formwork stud 5 vykruchivat is carried out of the building element, due to the fact that adjacent to the hairpin concrete takes the form of its threads, the construction element 1 is formed a channel 2 with a thread on its surface 6.

For lifting, transportation and installation of the construction element in place of the studs 5 in channel 2 is screwed to the fixture 4 lifting and installation such as mounting anchor bolt (eye bolt), corresponding to the length and diameter of the channel in the construction element (see Fig.7), to which can be attached to a supporting rope 11.

The presence of the channel with the thread on the work surface allows you to voracity in a threaded hole studs and bolts, eyebolts, and delete data elements after installation of the construction element into place. Thread channel 2 concrete building element, as well as carving in metal, can carry the load and provide a reliable connection device 4 for lifting and installation (anchor bolt) with a construction element that allows the safe transportation of the construction element. After moving the building element of the anchor bolt 4 (eye bolt) gets out, and the channel may be filled with cement mortar.

The experimental tests showed that the use of the proposed building element during installation of buildings and structures allows to provide ease when installing and removing the anchor bolt when is posobiya for lifting, that improves safety and productivity. Due to the simplicity of design of the device for lifting and mounting, clear its fixation in the body of the construction element is simplified operation slinging, increases the reliability and safety of slinging. This significantly reduces the time for the operation slinging and dismantling lifter. Due to the small size of the mortgage loan details, as well as the possibility of its extraction from the construction element after its fabrication, reduces the intensity of the construction element.

The invention can be used in the manufacture of building elements of different size and shape, thus avoiding the chipped concrete in place of seminolecounty mortgage details.
