Description

Assembly type of non-slip stairs

The present invention relates to a prefabricated staircase non-slip installed at the top of each floor of a stairway to prevent slipping on a stairway installed to connect the upper and lower floors of a building and a stairway installed in an outdoor park or a river site.

Conventionally, when finishing the horizontal and vertical parts of the stairs using cement mortar or artificial snow mortar, etc., on the base of the stairs constructed of reinforced concrete, the fixed mold member is fixed in the state of being embedded in the mortar that is placed on the tip of the horizontal part. It is proposed that the utility model publication No. 1994-0007055 is a prefabricated staircase non-slip consisting of a non-slip shape member which is then assembled and installed on the fixed mold member. When the non-slip members, which are prefabricated to the fixed members embedded in the horizontal part of each layer to be poured, are worn out, only the worn non-slip members can be separated from the fixed members and replaced with new fixed members. Will be.

However, while the above-described fixed mold member of the prior art is made of a metal material (more specifically, aluminum material), cement mortar or artificial mortar, which is placed on the base of the stairs, is an inorganic mineral that is not bonded to the fixed member of the metal material. As a result of the shrinkage when the cement mortar or artificial mortar is cured, the front end and the rear end of the fixed mold member are pointed out to be loosened with the hardened cement mortar, thereby generating a gap. The gap formed at the rear end can be concealed by a non-slip member installed in a prefabricated manner, but the mortar formed with a relatively thin thickness at the line and the rear end of the fixed member is dropped due to the impact repeatedly generated by the steps of people traveling through the stairs. The phenomenon appears, causing problems with the appearance of the stairs.

In addition, recently, in order to decorate the exterior of the stairs more beautifully, we have finished the stairs using a product called chemical cacion (trade name). Since the chemical cacion products are made of inorganic minerals such as cement mortar, As described, it is pointed out that when the chemical kacion is cured, it is released from the fixed member made of metal and generates a gap.

The present invention has been invented for the purpose of solving the above-mentioned problems in the prior art, a fixed mold member which is installed in the top end of the cement mortar layer which is placed on the horizontal plane and the vertical surface of the stair foundation and the upper surface of the fixed mold member In the staircase non-slip composed of non-slip shape members assembled and installed,

At the rear end of the fixed member, the rear end supporting plate supporting the horizontal horizontal finishing layer which is plastered with a certain thickness on the horizontal part of the cement mortar layer and the end of the inorganic horizontal finishing layer which is plastered on the upper surface of the rear supporting plate are not lifted. The rear end of the anti-jaw is characterized in that the protrusion is formed.

In addition, the front surface of the anchor portion of the fixed member is formed with an uneven portion for suppressing the shrinkage action during curing of the inorganic vertical finishing layer, the horizontal support layer is laid on the upper surface of the rear end support plate shrinkage when curing It characterized in that the anti-shrink projection is formed to protrude.

In addition, in order to increase the adhesion area with the cement mortar layer and to fix it to the cement mortar layer, an uneven portion is formed between the front anchor portion and the assembling protrusion formed on the bottom surface of the fixing die and each of the bottom surfaces of the assembling protrusion. It is characterized by being formed.

In addition, the front end of the fixed member is formed with a binding protrusion protruding toward the front than the vertical front surface, and the assembly protrusion is elastically bound at the inner corner where the non-slip plate and the front cover plate of the non-slip member is connected at right angles. Characterized in that the binding groove is formed.

The present invention is an inorganic horizontal horizontal finishing layer and a vertical finishing layer which is installed in a cement mortar layer to be placed on the base of the staircase and then plastered with a predetermined thickness on each of the upper surface of the horizontal portion and the front surface of the vertical portion of the cement mortar layer When finishing, there is an effect that the inorganic horizontal finishing layer and the vertical finishing layer to be finished is not the phenomenon that the rear end and the tip of the fixed shape member does not appear, and also the fixed shape member to be firmly attached to the cement mortar layer It is effective, and the non-slip member is elastically assembled and installed on the fixed member so that the phenomenon of being separated by the walking impact of people traveling to and from the stairs does not appear, and the effect of being replaced when the non-slip member is worn. To provide.
