Abstract
The utility model relates to a stair corner armor. The stair corner armor comprises angle steel (1) and steel bar claws (2), wherein the angle steel (1) is buckled on the external corner of an integral type stair; the steel bar claws (2) are positioned at the inner side of the angle steel (1) and fixedly connected with the angle steel (1), a plurality of the steel bar claws (2) are uniformly distributed on the angle steel (1) and fixed in external corner of the integral type stair through reinforced concrete, and the steel bar claws (2) are formed by steel bars with two hook-shaped end parts. The stair corner armor disclosed by the utility model can effectively reduce the damage of the external corner of an integral type stair made of cement mortars or the reinforced concrete, and the like, enhance the impression of the integral surface of the integral type stair and also enhance the strength and the durability of the external corner of the integral type stair and prolong the service life.
Description
Technical field
The utility model relates to a kind of Protective angle for stairs of building field, particularly a kind of Protective angle for stairs with the reinforcing bar pawl.
Background technology
Along with the builing industry market competition is growing more intense, very high requirement has been proposed for construction quality as the important component part-stair of engineering construction.Yet at present, most of stairway steps are not provided with arm of angle guard member, because the surface layer fragility of monolithic stair such as cement mortar stair or steel concrete is big; Intensity is low; Being easy in the use collides with causes the corner damaged, uneven, not only influences attractive in appearancely also to hack easily.And in a single day destroyed, very difficult reparation reaches former and produces effect.
The utility model content
The utility model technical issues that need to address provide a kind of external corner corner protector of monolithic stair, and this corner protector can increase the intensity of monolithic stair external corner, and durability is strong, long service life.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is:
A kind of Protective angle for stairs comprises the angle steel of spiral-lock at monolithic stair external corner place, in the concrete of the inboard stair of angle steel, also is arranged at intervals with the reinforcing bar pawl that is fixedly connected with angle steel.
The further improvement of the utility model is: said reinforcing bar pawl has three length directions that are distributed on angle steel at least, the spacing 300mm ~ 500mm between per two reinforcing bar pawls.
Further being improved to of the utility model: the length of said reinforcing bar pawl is 100mm ~ 150mm; Be fixed together through welding manner between reinforcing bar pawl and the angle steel.
Further being improved to of the utility model: said reinforcing bar pawl end is arranged to hook-shaped.
The utility model further is improved to: said reinforcing bar pawl is made up of two reinforcing bars, is 30 ° ~ 60 ° angles between two reinforcing bars.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
The utility model Protective angle for stairs is the safeguard measure of monolithic stair external corners such as a kind of cement mortar or steel concrete; When strengthening stair integral surface impression; Reduced destruction, improved the intensity and the durability of monolithic stair external corners, thereby prolonged application life external corner.
Protective angle for stairs comprises the reinforcing bar pawl that spiral-lock is fixedly connected with angle steel in the angle steel at monolithic stair external corner place and inboard at angle steel.The a plurality of reinforcing bar pawls that are evenly distributed on the angle steel are fixed in the monolithic stair external corner by cement mortar or steel concrete.Utilize angle steel to do the external corner of monolithic stair, improved intensity, rigidity and the durability of stair.Colliding with to stair when having reduced people's stair activity or carrying heavy goods.
The reinforcing bar pawl is made up of two reinforcing bars, and reinforcing bar pawl end is arranged to hook-shaped, makes angle steel be securely fixed in stair external corner place.And simple to operate, easy construction.
Description of drawings
Fig. 1 is the structural representation of the utility model monolithic Protective angle for stairs.
Fig. 2 is the Protective angle for stairs schematic cross-sectional view.
Wherein: 1. angle steel, 2. reinforcing bar pawl.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify:
The utility model is a kind of Protective angle for stairs, comprises angle steel 1 and reinforcing bar pawl 2, and angle steel 1 spiral-lock is at monolithic stair external corner place.Angle steel 1 can be equilateral or inequilateral, and its width is decided for looking specific requirement, and length is the concrete design length of stair step.Be uniform-distribution with at least three reinforcing bar pawls 2 along its length in angle steel 1 inboard, the spacing 300mm ~ 500mm between per two reinforcing bar pawls 2.Reinforcing bar pawl 2 welds together with angle steel 1 inboard bight.
Reinforcing bar pawl 2 is made up of the reinforcing bar of two band crotches, and the length of each reinforcing bar is 100mm ~ 150mm, is 30 ° ~ 60 ° angles between two reinforcing bars, and Protective angle for stairs is connected with stair through the reinforcing bar pawl that is cast in cement mortar or the concrete.
When doing monolithic stair surface layer, its step of the job practices of monolithic Protective angle for stairs is following:
A, according to the length of stair step, select the length of rational angle steel 1;
B, add welding steel muscle pawl 2 in the inboard bight of angle steel; Select the quantity of reinforcing bar pawl 2 according to the length of angle steel 1;
C, when doing the facing decoration of monolithic stair, be fixed on the stair step external corner angle steel is embedding in advance, build with cement mortar or concrete the back;
Carry out the facing decoration construction after D, the surface solidification.
Claims (5)
1. a Protective angle for stairs comprises the angle steel (1) of spiral-lock at monolithic stair external corner place, it is characterized in that: in the concrete of the inboard stair of angle steel (1), also be arranged at intervals with the reinforcing bar pawl (2) that is fixedly connected with angle steel (1).
2. Protective angle for stairs according to claim 1 is characterized in that: said reinforcing bar pawl (2) has three length directions that are distributed on angle steel (1) at least, the spacing 300mm ~ 500mm between per two reinforcing bar pawls (2).
