In order to solve the technical problems, the inventor obtains the technical scheme of the utility model through practice and summary, the utility model discloses a structure for controlling the molding of the external corner of a cement mortar surface layer of a stair step, which comprises a structure body arranged on the stair, wherein the stair comprises a tread and a skirt which are vertically arranged, the structure body is positioned in a stepped groove arranged at the joint of the tread and the skirt and matched with the stepped groove, the structure body is arranged at the edge of the stair step during installation, and the top surface and the vertical surface are kept flush with the stair step, so that the external corner of the stair step is ensured not to be damaged; an anti-slip groove is formed in the middle of the top of the structure body.

Furthermore, the structural body is connected with the stepped groove through gluing.

Furthermore, the width of the structure body is 3-4 cm, and the thickness of the structure body is 1-2 cm.

Furthermore, the width of the anti-skid groove is 1cm, and the depth of the anti-skid groove is 0.5cm.

Furthermore, the structure body is made of stone materials, and the problems that the stair tread external corner is easy to damage and not bonded by using a steel bar corner protector or a copper bar corner protector, and the damaged stair tread external corner is not easy to repair are solved.

Furthermore, the protective layer is arranged outside the structure body, so that the protective layer is combined with the hydroxyl in the capillary holes of the structure body made of the stone to form a net-shaped protective layer, thereby preventing the stone from being diseased and prolonging the service life.

Compared with the prior art, the utility model discloses can obtain following technological effect:

the utility model discloses the top surface of structure highly whitewashes the finish with stair tread, and the facade highly whitewashes the finish with the tread of marking time, uses the control of finished product external corner stone material realization to the roughness of stair tread to guarantee the squareness of external corner, perpendicular.

Simple structure, reasonable in design and construction are simple, have effectively solved current cement mortar stair and have marked time the easy damaged and non-stick and difficult prosthetic difficult problem after damaging of reinforcing bar angle bead or copper bar angle bead of using, have improved the efficiency of construction, have practiced thrift engineering cost, have fine use and spreading value.

Examples

As shown in figures 1-3, a structure for controlling the forming of the external corner of a cement mortar surface layer for stair steps, a structure body 2 is positioned in a stepped groove formed at the joint of a tread 11 and a kicking surface 12 vertically arranged on a stair 1, the structure body 2 is correspondingly matched with the stepped groove, the width is 3cm, the thickness is 2cm, an anti-skid groove 21 is formed in the middle of the top of the structure body 2,

the structure body 2 is made of stone, the stone and the stepped grooves are fixedly connected through gluing, the hardness of the stone is high, the problem that the stair is not easy to repair after being damaged can be solved, the appearance of the stone is attractive, the stone is bonded at the edge of the stair, and the stone has striking and prompting functions; meanwhile, the stone strips are self-aligned, so that the time for a constructor to brush the cement mortar out of the stair tread external corner is saved, and the construction efficiency is improved; the structure body 2 is externally coated with a protective layer which can be combined with hydroxyl in pores of the stone to form a net-shaped protective layer, so that the stone pathological change phenomenon is prevented.

During construction, a stair step tread line and a riser line are popped out in advance on a stair step or a stair side wall to ensure that the stair steps are uniformly distributed, the stair step tread line and the riser line which are drawn in advance are thrown onto the stair step by using an infrared laser level meter, and painting is carried out according to the position of the infrared line.

The concrete construction steps are as follows:

1. cleaning up the slag and the garbage of the surface layer of the reinforced concrete stair structure, watering to wet and coating cement paste, and ensuring that the cement paste coating layer is firmly bonded with the reinforced concrete structure layer without generating hollowing;

2. uniformly spreading the mixed cement mortar on the stair tread, painting the stair tread according to a stair tread finishing line popped from the stair tread or the side wall in advance, compacting a cement mortar painting layer, and ensuring that painting is compact;

3. when cement mortar distribution is carried out on the stair steps, a stepped groove with the width of 3cm and the height of 2cm is reserved at the edge of each stair step by using a plaster cutter, then stone strips are distributed by using the plaster cutter, after mortar is fully distributed, the structure is bonded at the edge of each stair step and compacted, the height of the surface of the stone is flush with that of a cement mortar surface layer, and the stone strips are glazed to ensure that mortar at joints of the stone strips is tight and seamless;

4. after the light is collected, the level and the verticality of the step are checked by infrared rays, and finally watering, moisturizing and maintaining are carried out.
