Abstract
A building anchorage device is composed of a pair of or two pressing plates sleeved on the reinforcing bars, and a pair of or two pairs of lining tiles surrounded by said reinforcing bars, and features that several transverse slots are made on the internal surface of said lining tiles, said transverse slots are matched with transverse ribs on reinforcing bars, and each pair of lining tiles has external screw thread and is linked with a nut. When the building anchorage provided by the invention is used, the nut is matched with the threads between the pair of lining tiles, and the nut presses the pressing plate, so that the fixed component can be clamped by the pressing plate.
Description
Technical Field
The invention relates to an anchorage device used in building construction.
Background
In building construction, anchors are often used. The existing building anchorage device consists of a bolt, a pressing plate and a nut, and is mainly used for fixing a template. Because such construction anchors are essentially disposable, they are relatively expensive to use.
Disclosure of Invention
The invention aims to provide a building anchorage which is prepared by using a twisted steel bar commonly used in building construction and can reduce the use cost.
In order to achieve the purpose, the invention adopts the following technical scheme: a building anchorage device is composed of a pair of or two pressing plates sleeved on the reinforcing bars, and a pair of or two pairs of lining tiles surrounded by said reinforcing bars, and features that several transverse slots are made on the internal surface of said lining tiles, said transverse slots are matched with transverse ribs on reinforcing bars, and each pair of lining tiles has external screw thread and is linked with a nut.
According to the scheme, when the building anchorage provided by the invention is used, the nut is matched with the threads between the pair of lining tiles, and the pressing plate is pressed by the nut, so that the fixed component can be clamped by the pressing plate.
The invention has simple and reasonable structure and convenient use, can be prepared by using the twisted steel bar on the construction site of the building, and saves the construction cost.
Drawings
FIG. 1 is a schematic structural diagram according to a first embodiment of the present invention;
FIG. 2 is a cross-sectional view A-A of FIG. 1;
fig. 3 is a schematic structural diagram of a second embodiment of the present invention.
Detailed Description
The invention is further illustrated below with reference to examples and figures.
See fig. 1 and 2
The construction anchorage provided by the embodiment comprises a twisted steel bar 1 and a pressing plate 2, wherein the twisted steel bar 1 is sleeved with the pressing plate 2, the twisted steel bar 1 is surrounded by a pair of lining tiles 4, the inner surface of each lining tile 4 is provided with a plurality of transverse grooves 4a, the transverse grooves 4a on the lining tiles 4 are matched with transverse ribs 1a on the twisted steel bar 1, the outer surface of each lining tile 4 is provided with external threads, and the pair of lining tiles 4 are connected with a nut 3 through the external threads on the lining tiles 4.
The inner surface of the lining tile 4 is a cylindrical surface, the distance between the transverse grooves 4a on the lining tile 4 corresponds to the distance between the transverse ribs 1a on the twisted steel 1, and the transverse grooves 4a are matched with the profiles of the transverse ribs 1 a.
In this embodiment, the outer surface of the lining tile 4 is provided with through grooves 4b extending along the circumferential direction and penetrating through both sides thereof, the through grooves 4b of the pair of lining tiles 4 are bundled with steel wires 5, and the steel wires 5 restrict the pair of lining tiles 4 to the rebar 1.
See FIG. 3
In this embodiment, the edges of the two sides of the inner wall of the lining tile 4 are respectively provided with notches 4c extending along the longitudinal direction, the notches 4c penetrate through the two ends of the lining tile 4, the twisted steel bar 1 is provided with longitudinal ribs 1b, and the longitudinal ribs 1b of the twisted steel bar 1 are positioned in the notches 4b of the pair of lining tiles
Referring to fig. 1 and 2, when the building anchorage provided by the first embodiment is used, one end of a rebar 1 is fixed on a fixture, a pressing plate 2 is close to a component to be fixed, a pair of lining tiles 4 are wrapped on the rebar 1 and close to the pressing plate 2, a steel wire 5 is loaded into a through groove 4b, the pair of lining tiles 4 are bound by the steel wire 5 and limited on the rebar 1, and then a nut 3 is connected with the pair of lining tiles 4, so that the nut 3 can be adjusted to press the pressing plate 2, and the component to be fixed is clamped by the pressing plate 2.
Referring to fig. 3, the difference between this embodiment and the first embodiment is that two pressing plates 2 are sleeved on the rebar 1, the two pressing plates 2 are arranged in opposite directions, two pairs of lining tiles 4 are surrounded on the rebar 1, and each pair of lining tiles 4 is connected with a nut coupling 3 through external threads on the pair of lining tiles 4. When the building anchorage device is used, a component needing to be fixed is positioned between the two pressing plates 2 and is clamped and fixed by the two pressing plates 2.
