Technical Field

The utility model belongs to the technical field of the construction, specifically speaking relates to a stair angle bead of marking time.

Background

Stairs are often indispensable building components in residential, commercial and public building design, and the surface course of the cast-in-place reinforced concrete stair step is also many, wherein the most common method is cement mortar surface course. The stair is composed of multiple steps, the steps have more external corners, no reinforcing measures or only single reinforcing steel bars are used for reinforcing the external corners of the steps in the using process of the stair, the local damage of the external corners of the steps is easy to occur, the repair of the damaged external corners of the steps is troublesome, the color of the repaired steps is difficult to keep consistent with the original color, and the attractiveness is affected. If the damage is serious, the use function of the cable is affected if the cable is not repaired in time.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects, the utility model provides a stair corner protector of marking time to the easy damaged technical problem of external corner when solving the construction of current like structure, its purpose is realized through following technical scheme.

A stair step corner protector comprising:

angle steel;

the T-shaped ribs are arranged on any surface of the angle steel at intervals along the length direction of the angle steel, any T-shaped rib comprises a connecting rib and an extending rib, one end of the connecting rib is connected with the surface of the angle steel where the connecting rib is located, the other end of the connecting rib is connected with the extending rib, and the connecting rib and the extending rib form a T shape,

the angle steel is used for being arranged at the external corner position of the stair tread surface layer, and the T-shaped ribs are used for being embedded into the cement mortar surface layer of the stair tread riser and the tread.

Optionally, the T-shaped rib is welded with the angle steel into a whole.

Optionally, the T-shaped ribs are spaced between 100mm and 200mm apart.

Optionally, the length of the T-shaped ribs is not less than 60mm.

Optionally, a plurality of grooves are formed in the tread of the angle steel along the length direction of the angle steel, so that an anti-skid effect is achieved.

Optionally, round steel with the diameter not less than phi 3mm is adopted as the T-shaped rib.

Compare with stair cement mortar surface course external corner does not have the reinforcement measure or only single reinforcing bar reinforcement measure in the past, this application adopts the angle steel in external corner department of marking time, has improved the angle bead area of stair cement mortar surface course external corner of marking time, greatly reduced the probability that stair external corner of marking time damaged, reduced the later stage maintenance frequency of stair external corner of marking time. Meanwhile, the angle steel has a groove effect, and a certain anti-skidding effect is achieved.

Detailed Description

The embodiments of the present invention will be described below with reference to the accompanying drawings. Those of ordinary skill in the art will recognize that the described embodiments can be modified in various different ways, or combinations thereof, without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive on the scope of the claims. Furthermore, in the present description, the drawings are not to scale and like reference numerals refer to like parts.

The stair corner bead of marking time of this embodiment includes angle steel 1 and T shape muscle 2, angle steel 1 can be L50X 3 mm's angle steel, and its length can be decided by oneself according to the external corner length that actual stair marked time, and angle steel 1 acts on the external corner of marking time for improve the bulk strength of cement mortar surface course external corner of marking time.

T type muscle 2 can adopt phi 3 mm's round steel, on the arbitrary face place plane of angle steel 1, is connected with a plurality of T type muscle 2 along angle steel 1's length direction interval, and T type muscle 2 can form a whole with angle steel 1 through the welding, and the interval of arranging of T type muscle 2 on angle steel 1 can be decided by oneself, but should not too big or undersize, and the interval is that 100mm is suitable to 200mm, evenly arranges.

Each T shape muscle 2 includes splice bar 21 to and extension muscle 22, and the one end of splice bar 21 is connected rather than the face of place angle steel, and extension muscle 22 is connected perpendicularly in the other end of splice bar 21, forms the T type with splice bar 21.

The length of the connecting rib 21 can be determined according to the height of the tread and the width of the tread, but the shortest length is not lower than 60mm, and the longest length is not larger than the height of the tread and the width of the tread. During construction, the T-shaped ribs 2 are embedded into the cement mortar surface layers of the stair step riser and the stair tread and used for fixing the stability of the angle iron 1 in the cement mortar surface layers.

When the stair step cement mortar surface layer is constructed, the angle steel 1 is arranged at the external corner of the cement mortar surface layer step and is at the same height with the cement surface, the T-shaped rib 2 is simultaneously embedded into the tread of the step and the tread of the step of 3mm, the T-shaped rib 2 can increase the stability of the angle steel 1, and meanwhile, the angle steel 1 and the T-shaped rib 2 are made of rigid materials and have certain rigidity, so that the integrity and the strength of the external corner part of the cement surface step are increased.

Furthermore, a plurality of grooves 11 are formed in the tread of the angle iron 1 along the length direction of the tread, so that an anti-skid effect is achieved.

Further, as shown in fig. 4 and 5, the connecting rib 21 extends to a preset length in the plane of the angle steel and then bends towards the inside, so that on one hand, the external strength of the surface layer can be improved, and the T-shaped rib can be combined with cement mortar in the surface layer more tightly and firmly. The preset length is not particularly limited, and may be set according to the need, for example, half the length of the connecting rib 21. The angle of buckling to the inside can satisfy and make T type muscle 2 can not interfere with foundation bed 3 when the construction, can arrange in cement mortar surface course 4 can. Furthermore, the connecting rib 21 extends to a preset length in the surface of the angle iron and then bends towards the inner side in a space curve, for example, spirally bends, so as to further enhance the tightness degree of the bonding with the cement mortar in the surface course.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
