Abstract

The utility model discloses an anchor nail, including two nails and a base. The base is n-shaped, two nails are respectively connected with both ends of the base, and the base and the nail are arranged on two vertical planes. The utility model arranges the n-shaped base between two nails on a vertical plane and improves the original point contact to the surface contact; the welding is convenient with high firmness, thus having less rupture, reducing the use of anchor nails per unit area and the cost. The front part of the linear nail is improved to a wavy bending nail, which enhances the adhesion of the nail.

Description

Anchor studs

[technical field]

The utility model relates to anchor studs, relates in particular to the single-layer lining anchor studs.

[background technology]

In the industry of all kinds of employing high-temperature furnace bodies or body of wall, at the general lining that all is lined with castable refractory and skeleton formation of body of heater or body of wall.Usual earlier adopts hexsteel to make skeleton, hexsteel is welded on the inner surface of equipment, and ramming cast refractory heat-insulating material in the tortoise plastron mesh then makes lining closely knit and have a certain compression strength.But this structure steadiness is relatively poor, and service life is short, and especially the junction of hexsteel is easy to cracking under the condition of high temperature, lining come off the present situation of base is happened occasionally, thereby influenced the normal operation of producing.

For overcoming the defective of hexsteel, at present anchor studs that adopt the V-type nail as single-layer lining more, the summit that V-type is followed closely is welded on the furnace wall.This structure can only adopt the welding manner of a contact, and contact area is little, and welding is inconvenient, is easier to fracture after the welding, so need to use more anchor studs on the unit are.And the nail body is a linear, and adhesive force is little.

[summary of the invention]

The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of anchor studs, and is bigger with the contact area of furnace wall, convenient welding, and the use amount of anchor studs firmly can be saved in the welding back.

For achieving the above object, the utility model proposes a kind of anchor studs, comprise two nail bodies, also comprise base, described base is a n shape shape, and two nail bodies link to each other with the two ends of base respectively, and base is on two vertical planes with the nail body.

As preferably, the back segments of described two nail bodies are linear, and leading portion is the wave curved shape.

As preferably, constitute 60 °-120 ° angle between the leading portion of described two nail bodies.

The beneficial effects of the utility model: the utility model is provided with the n shape base that is in vertical plane with the nail body between two nail bodies, original summit contact is improved to the face contact, convenient welding, welding back firmness height, not only be not easy fracture, also reduce the use amount of anchor studs on the unit are, reduced cost.The leading portion of rectilinear nail body is improved to the nail body of wave curved shape, has strengthened the adhesive force of nail body.

Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.

Fig. 1 is the structural representation front view of the utility model anchor studs;

Fig. 2 is the structural representation upward view of the utility model anchor studs.

[specific embodiment]

Fig. 1 is the structural representation front view of the utility model anchor studs; Comprise two nail bodies 2, also comprise base 1, described base 1 is a n shape shape, and two nail bodies 2 link to each other with the two ends of base 1 respectively, and base 1 is on two vertical planes with nail body 2.The parallel placement of base 1 during welding with the furnace wall, two nail bodies 2 are vertical with the furnace wall, and n shape base 1 welds with the furnace wall, and contact area is bigger, this contacting structure welding back firmness height.So the use amount of anchor studs can reduce on the unit are, has reduced cost.

Take all factors into consideration the stressed and distribution of nail body 2, constitute 60 °-120 ° angle between the leading portion of preferred two nail bodies 2.The area of Fu Gaiing is bigger like this, can meet stressed requirement again.

Fig. 2 is the structural representation upward view of the utility model anchor studs.Be the adhesive force of strengthening nail body 2, the back segment of described two nail bodies 2 is a linear, and leading portion is the wave curved shape.Crooked length and amplitude set up on their own as required.

The foregoing description is to explanation of the present utility model, is not to qualification of the present utility model, and any structure after simple transformation on the utility model basis all belongs to protection domain of the present utility model.
