Description

Cantilevered steel beam U-shaped anchor bolt fixer

technical field

The utility model belongs to the field of cantilevered steel beam anchoring engineering, in particular to the fixing of temporary cantilevered steel U-shaped anchor bolts such as shaped steel cantilevered scaffolds and tool unloading platforms used in the building structure construction process.

Background technique

In modern cities, due to the increasing height of buildings due to the tension of the land, temporary cantilevered structures such as steel cantilevered scaffolding and tool-type unloading platforms are widely used in the construction process, and the U-shaped anchor bolts used for cantilever anchorage are embedded In cast-in-place concrete structures, high-energy gas is often used for cutting when removing temporary cantilevered steel beams, and U-shaped anchors can only be used once, resulting in a lot of waste. Therefore it is very necessary to invent a device that can make the U-shaped anchor bolt capable of turnover and reuse.

Utility model content

In order to solve the above problems, the utility model proposes a U-shaped anchor bolt fixer for a cantilevered steel beam.

The technical scheme of the utility model is:

A U-shaped anchor bolt fixer for a cantilevered steel beam, the fixer includes a fixer body and protective sleeves located at both ends of the body, the fixer body includes protruding cylindrical parts at both ends and connected to the two cylindrical parts The bridging portion between the bridging portion and the lower part of the cylindrical portion is a cavity without a bottom surface, and the outer surface of the upper half of the cylindrical portion is provided with a water-swellable water-stop strip; The barrel is provided on the upper portion of the cylindrical portion.

A part of the water-swellable water-stop strip is embedded in the outer surface of the cylindrical part.

The upper end surface of the cylindrical part is provided with an inner stepped hole, and the diameter of the inner stepped hole matches the diameter of the casing.

The fixer body is made of cement mortar, and the outer surface is rough.

The lower part of the fixer body is provided with an outward edge, and screw holes are arranged on the edge.

The beneficial effects of the utility model:

The cantilevered steel U-shaped anchor bolt fixer has simple design, convenient production and low cost, which enables the cantilevered steel U-shaped anchor bolt to be recycled and reused, greatly saves the amount of steel used, and achieves good benefits of cost saving, energy saving and emission reduction .

Detailed ways

Referring to Fig. 1-Fig. 7, a cantilevered steel beam U-shaped anchor bolt fixture in the figure, the fixture includes a fixture body and casings located at both ends of the body, and the fixture body includes protruding cylinders at both ends part and a bridging part connected between the two cylindrical parts, the lower part of the bridging part and the cylindrical part is a cavity without a bottom surface, and the outer surface of the upper half of the cylindrical part is provided with water Expandable water stop strip; the casing is arranged on the upper part of the cylindrical part. A part of the water-swellable water-stop strip is embedded in the outer surface of the cylindrical part. The upper end surface of the cylindrical part is provided with an inner stepped hole, and the diameter of the inner stepped hole matches the diameter of the casing. The fixture body is made of cement mortar, and the outer surface is rough. The lower part of the fixer body is provided with an outward edge, and screw holes are arranged on the edge.

The usage process is as follows:

Pop up the center positioning line of the cantilevered steel U-shaped anchor bolt on the template; insert the cantilevered U-shaped steel anchor bolt into the fixer, insert the U-shaped anchor bolt casing, and screw in the nut to fix the casing to form a combination. The quasi-bolt center positioning line is placed on the formwork and nailed into the iron nail to fix it;

Use a plastic film or a special protective sleeve to protect the U-shaped anchor wire mouth section, then bind the structural steel bars, and add anchor bolts to anchor the steel bars to complete the structural concrete pouring;

After the strength of the structural concrete reaches the master's operating standard, the U-shaped anchor bolt protection sleeve is recovered, and the cantilevered steel is fixed to perform the function of the cantilevered steel;

When dismantling, remove the section steel first, and then take out the section steel cantilevered U-shaped anchor from the lower part of the structure.
