Abstract

The utility model relates to a reinforcing device for preventing end failure of stair ornamental stones, which is characterized in that a reinforcing plate is lined under a cantilever position of the ornamental stone of the stair pedal surface; and the reinforcing plate extends 30 to 60 mm on a stair pedal surface body in the width direction. The utility model has the advantages of simple structure and convenient construction, and can effectively prevent the end failure of the stair ornamental stones.

Description

Prevent the bracing means of stairway step decorative stone broken end

Technical field

The utility model relates to civil construction, municipal engineering field, relates in particular to the bracing means that prevents stairway step decorative stone broken end.

Background technology

At present the phenomenon that ruptures often appears in the decorative stone on the stairway step, its reason is that the decorative stone on the step is a cantilever in the outer end of tread, stressed bigger, traditional way is that this stone material cantilever outer end has only been carried out the thickening reinforcement or do not thickeied reinforcement at its bracketed part, but the position of fracture is not again in the outside of cantilever but at the root of cantilever or the tread end by cantilever, therefore, in fact this does not solve basic problem, finally cause the decorative stone on the step to lean on one of cantilever to bring out the phenomenon of existing fracture at the root or the tread of cantilever, both influenced attractive in appearance, also influence result of use, can be when repairing or changing because the aberration reason of material causes decorative effect not good.

Summary of the invention

The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, and proposes a kind of simplely, can prevent effectively that the bracing means of fracture from appearring in stairway step decorative stone end.

For realizing above-mentioned purpose, the utility model adopts following technical scheme: the bracing means that prevents stairway step decorative stone broken end, it is characterized in that this device is gusset plate of lining under the decorative stone cantilever position of step tread, the width of its gusset plate extends to 30-60mm on the step tread body.

The gusset plate that serves as a contrast under the decorative stone cantilever position of step tread can be selected the material the same with the decorative stone of step tread for use, also can select thick aluminium-plastic panel of 2-4mm or aluminium alloy plate for use.

In such scheme, on step tread body, offer a tongue and groove with gusset plate width extending part corresponding position, this tongue and groove can hold the extending part of gusset plate width, at the body of step tread and laying adhesives above the tongue and groove, will be laid on the above-mentioned adhesives with the gusset plate that step decorative stone cantilever position is pasted together below.

The utility model is simple in structure, and easy construction can prevent effectively that fracture from appearring in stairway step decorative stone end.

The specific embodiment

Embodiment 1, referring to Fig. 1, press usual way construction step tread body 1 earlier, it is wide then 30-60mm to be cut in step tread body 1 outer end, about high 15mm with the tongue and groove 2 of step length, step decorative stone 5 is added sticking gusset plate 4 below the cantilever position, this adds the width (30-60mm) that sticking gusset plate 4 width are the cantilever width+above-mentioned tongue and groove of step decorative stone 5, again with above-mentioned below step tread cantilever position the step decorative stone 5 of strengthening with external bonding plate 4 be laid on the step tread body 1, gusset plate 4 is embedded in the tongue and groove 2, and bonding with adhesives 3.Gusset plate 4 can be selected the material same with step decorative stone 5 for use.

Embodiment 2, referring to Fig. 2, the working face of step tread body 1 descended about 15～20mm than conventional job practices, and promptly the tread of step tread body 1 is flat, for step decorative stone 5 strengthens reserving height in its cantilever position thickening; Step decorative stone 5 is added sticking gusset plate 4 below the cantilever position, this adds cantilever width+30-60mm that sticking gusset plate 4 width are step decorative stone 5; On the tread of step tread body 1, lay the adhesives 3 (do not contain in the stone material reinforcing scope, the adhesives thickness in the stone material reinforcing scope still is conventional thickness) of the step about thick 15mm then than conventional method; At last below step tread cantilever position the decorative stone of strengthening with external bonding plate 4 be installed on the adhesives 3.

Embodiment 3, referring to Fig. 3, by usual way the tread of step tread body 1 directly made the embodiment 1 described step that contains tongue and groove 2, and all the other are identical with embodiment 1.

Embodiment 4, referring to Fig. 2, step decorative stone 5 added a sticking thin gusset plate 4 below the cantilever position, and this adds sticking thin gusset plate 4 width is the cantilever width+30-60mm of step decorative stone 5; Press the tread of usual way construction step tread body 1, promptly the surface of step tread body 1 is flat, does not have tongue and groove, lays adhesives 3 on the surface of step tread body 1 then, and all the other are identical with embodiment 1.

Claims

1, prevent the bracing means of stairway step decorative stone broken end, it is characterized in that this device is gusset plate of lining under the decorative stone cantilever position of step tread, the width of its gusset plate extends to 30-60mm on the step tread body.

2, the bracing means that prevents stairway step decorative stone broken end according to claim 1, it is characterized in that the gusset plate that serves as a contrast adopts the material the same with the decorative stone of step tread under the decorative stone cantilever position of step tread, or thick aluminium-plastic panel or the aluminium alloy plate of 2-4mm.

3, the bracing means that prevents stairway step decorative stone broken end according to claim 1, it is characterized in that on step tread body, offering a tongue and groove with gusset plate width extending part corresponding position, this tongue and groove can hold the extending part of gusset plate width, at the body of step tread and laying adhesives above the tongue and groove, will be laid on the above-mentioned adhesives with the gusset plate that step decorative stone cantilever position is pasted together below.
