Abstract
The utility model relates to a hot-rolled steel built-in connector for concrete. The utility model is in a groove shape and is provided with a notch, wherein a threaded bolt is arranged on the top of the groove, and a T-shaped connecting threaded bolt with a bolt part of a threaded bolt is arranged in groove feet of both sides. The inner side surfaces of the two groove feet are all provided with denticles, two inner side dentiform surfaces are formed, and the two dentiform surfaces are connected with two inner side surfaces of the bolt part of the T-shaped connecting threaded bolt in a fastening mode. The built-in connector of the utility model designs the inner side plane surfaces of the groove feet into the dentiform surfaces, and the inner side plane surfaces is tightly and firmly matched with the inner side dentiform surfaces of the bolt part of the T-shaped threaded bolt; no matter the built-in connector beforehand buried in a concrete structure is designed into vertical or transverse, the efficacy of three-dimensional fastening can be totally reached, and unnecessary welding procedures do not need to be added on a fastening piece to prevent transverse or vertical displacement of the built-in connector later. The built-in connector of the utility model is made of hot-rolled steel, compared with the existing groove-shaped connecting casting, the weight of the connector is lighter, the corrosion is not easy, the construction and the installation are convenient, and the service life is prolonged.
Description
Technical field
The utility model relates to the concrete connector, particularly a kind ofly is used for concrete hot-rolled steel built-in connection.
Background technology
The concrete embedded connector of existing grooved is generally made by casting and cold rolling process.On the groove top of this grooved connector bolt is housed, can install T type connecting bolt in the two side channel pin, because the groove pin is inboard and T type bolt spigot inboard is the plane, built-in connection just is easy to skid after T type bolt is installed, cause the tightness of T type bolt and connector groove pin relatively poor, will bring construction hidden danger to building decoration thus.Secondly, on existing securing member, also need during construction to weld, to stop its horizontal or vertical displacement.Have, it is heavier that existing grooved connects casting weight again, and corrosion was easily both made troubles to construction and installation, had influence on application life again, therefore is necessary to be improved.
Summary of the invention
Task of the present utility model provides a kind of improved hot-rolled steel built-in connection for concrete, the problem that it has solved, and existing grooved connects that foundry goods is relatively poor with the tightness of T type connecting bolt, weight is heavier, easy corrosion, construction and installation inconvenience, application life are lacked.
The technical solution of the utility model is as follows:
A kind of hot-rolled steel built-in connection for concrete, it is flute profile and has notch, on the groove top bolt is housed, and installing has the T type connecting bolt of bolt spigot in two side channel pin, and described built-in connection is made by hot-rolled steel; The inner surface of described two groove pin is equipped with little tooth, forms two inboard toothed surface, and two medial surfaces of two toothed surface and T type connecting bolt spigot are fastenedly connected.
Hot-rolled steel built-in connection for concrete of the present utility model is designed to toothed surface with groove pin inner side plane, make cooperate closely with the toothed surface of T type bolt spigot inboard, firm, and no matter this built-in connection is designed to vertically or laterally is embedded in the concrete structure in advance, can both reach three-dimensional fastening effect, again need not on securing member, add unnecessary welding sequence later on and stop its horizontal or vertical displacement.
Built-in connection of the present utility model is made by hot-rolled steel, is connected foundry goods with existing grooved and compares, and this connector weight is lighter, is not easy corrosion, construction install convenience, and prolonged application life.
This built-in connection maximum antidetonation lateral resistance in use can reach the 57KN/ bolt, be existing more than 10 times of built-in connection lateral resistance, because the maximum transversal resistance of general connector is the 5KN/ bolt only, the connector that has even do not have lateral resistance.This shows that common built-in connection is the designing requirement that can not satisfy building operations fully, more can not really reach the shock resistance more than seven grades.
Description of drawings
Fig. 1 is the structural representation of a kind of hot-rolled steel built-in connection for concrete of the present utility model.
Fig. 2 is the A-A sectional drawing among Fig. 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model is a kind of hot-rolled steel built-in connection for concrete, this connector is flute profile 1 and has notch 11, in the bolt hole on groove top 12, bolt 2 is installed, installing T type connecting bolt in the notch 11 of two side channel pin 13, this T type bolt is provided with the spigot that is compressed two side channel pin 13.
Inner surface at two groove pin 13 is equipped with little tooth 14, forms two inboard toothed surface 15.The inboard toothed surface 15 of two of groove pin 13 is fastenedly connected with two medial surfaces of T type connecting bolt spigot, so that the two medial surface cooperates closely and firmly.
Be arranged on two little teeth 14 on the groove pin toothed surface 15 and can serration promptly interruptedly be set for the serration of continuity setting; Also can serration promptly be set with interval for the interrupted serration that is provided with.
The T type connecting bolt spigot that securely is connected with groove pin toothed surface 15, its two medial surfaces can all be made as the plane, also two medial surfaces of T type connecting bolt spigot all can be provided with little tooth, to form two inboard toothed surface, can more closely firmly be connected with two groove pin toothed surface 15 thus.
Built-in connection of the present utility model is to be made by hot-rolled steel, is easier to machine-shaping.
The utility model if be subjected to any one impact or vibrations, can not make securing member get loose after fastening with T type connecting bolt, can reach bigger safety and reliability thus.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the utility model, and be not with opposing qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claim variation, the modification of the foregoing description.
