Description

A kind of corner square staff with angle bead

Technical field

This utility model relates to square staff technical field, specifically, is about a kind of corner corner protector with angle bead Bar.

Background technology

The corner work progress that China is existing, has followed the conventional construction method of more than ten years, and efficiency is low, and engineering is loaded down with trivial details, and And after being completed building in use, corner is very easy to the damage that caused by cracking.On the one hand it is corner location contacts The reason that frequency is too high, is on the other hand owing to the firmness degree in corner is inadequate, owing to the corner after damaging does not has again specialty dimension The personnel of repairing go maintenance so that construction quality declines, especially door and the corner of window.At present, home dwelling is typically taked at bound edge Reason, but this finishing mode not only wastes timber, causes the biggest pollution, and returns finishing and bring the wave of many funds Take.

Square staff be a kind of on body of wall operation use, make the more neat and artistic a kind of section bar in corner.Meanwhile, corner protector Bar can reinforce corner, it is to avoid indenture and other damages occurs in corner.It addition, because of its construction easily, the plenty of time can be saved, has Wide applicability.But existing square staff is little with the contact area of body of wall, and anti-impact force is little, and the service life in corner is short. It is therefore desirable to improved.

Utility model content

The purpose of this utility model is to provide a kind of corner square staff with angle bead, to solve existing corner, door Edge strip construction problem difficult, easily cracking.

For achieving the above object, this utility model is by the following technical solutions:

A kind of corner square staff with angle bead, including L-shaped square staff body and an angle bead, described in protect Angle bead body is made up of two orthogonal wing plates, and two wing plates are one-body molded, and described wing plate is provided with some through holes, described The longitudinal section of through hole is T-shape, and the described through hole diameter near body of wall side is less than the diameter away from body of wall side, described through hole Inside be provided with female thread, described angle bead is coated on the outside of square staff body, and each extends over out two wing plates.

According to this utility model, it is 10～15cm that angle bead extends the distance of wing plate.

According to this utility model, described wing plate is notch cuttype, and the wing plate thickness near side, corner is more than away from side, corner Thickness.

Further, the wing plate away from side, corner is provided with a projection, and described projection is provided with external screw thread, to guarantee corner protector Bar is fixing more firm, reliable with body of wall.

Further, at described protruding corresponding body of wall, a groove is set.During construction, projection is inserted in groove so that Square staff body is fixed together with body of wall, further ensures that square staff body does not bends.

Corner square staff with angle bead of the present utility model, it provides the benefit that:

1, this physical ability of square staff is effectively protected corner, is provided with, within square staff, the through hole that longitudinal section is T-shape, and is Female thread, after being coated with slurry, forms the connection that is screwed, solid and reliable.

2, described angle bead is coated on the outside of square staff body so that square staff increases with the contact area of body of wall, from And increase the impact resistance of square staff, extend the service life in corner；Meanwhile, after the slurry of way, due to angle bead tightly Cladding square staff body, is possible to prevent square staff body to bend, also makes square staff body contact more closely with body of wall, prevent Square staff comes off.

3, described wing plate in notch cuttype, the wing plate thickness near side, corner is more than away from the thickness of side, corner.Due to wall Body corner is easily damaged, and under conditions of guaranteeing that square staff body corner thickness is enough, arranges the wing plate of notch cuttype, permissible Save the material of wing plate；It addition, the thickness of square staff corner can be as the scale being coated with slurry desired thickness.

Accompanying drawing explanation

Fig. 1 is the structural representation that corner of the present utility model square staff is arranged on body of wall.

Fig. 2 is the front view of corner square staff.

Fig. 3 is the rearview of corner square staff.

Detailed description of the invention

Below in conjunction with concrete accompanying drawing, to the corner corner protector row culture with angle bead of the present utility model the most specifically Bright.

As shown in Figure 1, Figure 2 and Figure 3, for the corner square staff with angle bead of the present utility model, L-shaped including one Square staff body 1 and angle bead 2, described square staff body 1 is made up of two orthogonal wing plates 11, two wing plates 11 1 Body formed, described wing plate 11 is provided with some through holes 3, and the longitudinal section of described through hole 3 is T-shape, and described through hole 3 is near body of wall 4 The diameter of side is less than the diameter away from body of wall 4 side, and the inside of described through hole 3 is provided with female thread, and described angle bead 2 is coated on The outside of square staff body 1, and each extend over out two wing plates 11.

It is 10～15cm that angle bead 2 extends the distance of wing plate 11.

Described wing plate 11 is in notch cuttype, and the wing plate 11 thickness near side, corner 41 is more than the thickness away from side, corner 41.

Further, the wing plate 11 away from side, corner 41 is provided with a projection 5, and described protruding 5 are provided with external screw thread, with really Protection angle bead is fixing more firm, reliable with body of wall 4.

Further, at the body of wall 4 of described protruding 5 correspondences, it is provided with a groove 42, during construction, projection 5 is inserted groove 42 In so that square staff body 1 is fixed together with body of wall 4, further ensures that square staff body 1 does not bends.

Use step with the corner square staff of angle bead of the present utility model is as follows:

Step one: cleaning external corner work surface, roots out the projection on body of wall, and filling-in is caved in；

Step 2: be fabricated to paste slurry with putty, stir；

Step 3: slurry is put on both sides, corner, and keeps certain thickness；

Step 4: square staff body 1 is close to corner, finds horizontal vertical accurately, scrapes off the slurry that hole overflows；

Step 5: dried, with external corner top for location limit Puttying；

Step 6: after drying with sand papering, and complete the construction of coating or wallpaper.

The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve and Retouching also should be regarded as protection domain of the present utility model.
