Abstract
The utility model discloses a kind of corner protector of prefabricated assembled clear water stair, comprise the angle steel being arranged on stair step external corner, described angle steel and anchor bar are welded to connect, soldering angle is 60 ° ± 10 °, described anchor bar is embedded in the concrete structure of stair in advance, and described anchor bar end makees 180 ° of curved anchors.The utility model is than traditional plastic protective angle bead, reinforcement protection bar; improve the intensity of stair step in essence; have protection domain greatly, not corrosion, use resistance to advantage of waiting so long; protection corner for stair step and staircase structure are tightly fitted simultaneously; therefore the external corner of stair step becomes not only straight but also attractive in appearance; thus form smoothly clean and tidy stair step external corner, improve the aesthetic measure of stair.
Description
Technical field
The utility model relates to a kind of corner protector of prefabricated assembled clear water stair, belongs to construction engineering technical field.
Background technology
In construction work, the steel concrete clear water stair not doing decorative layer are because of economic and practical and extensive use.Current prefabricated assembled clear water stair at the scene in work progress finished product do not protect use that the is not in place and later stage, very easily cause the damage of external corner part of marking time.To be plastered process by the later stage, both added construction costs, intensity of plastering also cannot meet the requirement of Long-Time Service.Currently available technology needleless is to the effective protective device of prefabricated assembled stair step external corner part.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is, there is provided a kind of anti-skidding corner protector of marking time of simple, practical prefabricated assembling type reinforced concrete clear water stair, this device can obviously improve stair step intensity and application life, saves later stage decoration and repair maintenance expense.
The technical solution of the utility model is: a kind of corner protector of prefabricated assembled clear water stair, it is characterized in that, comprise the angle steel being arranged on stair step external corner, described angle steel and anchor bar are welded to connect, soldering angle is 60 ° ± 10 °, described anchor bar is embedded in the concrete structure of stair in advance, and described anchor bar end makees 180 ° of curved anchors.
The corner protector of aforesaid a kind of prefabricated assembled clear water stair, it is characterized in that, described angle steel is stainless steel unequal angle.
The corner protector of aforesaid a kind of prefabricated assembled clear water stair, is characterized in that, the tread length of side of described stainless steel unequal angle is 50mm, and the riser length of side is 25mm, and thickness is 3mm.
The corner protector of aforesaid a kind of prefabricated assembled clear water stair, it is characterized in that, described anchor bar is bar dowel, and the diameter of described bar dowel is 6 ~ 12mm, and length is 20 times of diameter.
The corner protector of aforesaid a kind of prefabricated assembled clear water stair, is characterized in that, described anchor bar is 3 ~ 6 right.
The corner protector of aforesaid a kind of prefabricated assembled clear water stair, it is characterized in that, described anchor bar is plain bar or indented bars.
The beneficial effect that the utility model reaches: the utility model is than traditional plastic protective angle bead, reinforcement protection bar; improve the intensity of stair step in essence; have protection domain greatly, not corrosion, use resistance to advantage of waiting so long; protection corner for stair step and staircase structure are tightly fitted simultaneously; therefore the external corner of stair step becomes not only straight but also attractive in appearance; thus form smoothly clean and tidy stair step external corner, improve the aesthetic measure of stair.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the part-structure schematic diagram that the utility model is embedded in prefabricated fair-faced staircase structure in advance;
Fig. 3 is the complete structure schematic diagram that the utility model is embedded in prefabricated fair-faced staircase structure in advance.
In figure, the implication of each Reference numeral is: 1. anchor bar; 2. stainless steel unequal angle; 3. the concrete structure of stair.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1 to Figure 3, a kind of anti-skidding corner protector of prefabricated assembled clear water stair, comprise the stainless steel unequal angle 2 being arranged on stair step external corner, described stainless steel unequal angle 2 is welded to connect with anchor bar 1, described anchor bar 1 is bar dowel (plain bar or indented bars), the diameter of described anchor bar 1 is 6 ~ 12mm, and length is 20 times of diameter.This example is 6mm reinforcing bar length 120mm.
Described anchor bar 1 is embedded in the concrete structure 3 of stair in advance, is 3 ~ 6 right.Described anchor bar 1 end makees 180 ° of curved anchors, to improve and concrete anchoring strength.Anchor bar 1 obtains from reinforcing bar waste material, cost-saving.
Described stainless steel unequal angle 2 is 60 ° ± 10 ° with the soldering angle of anchor bar 1, and this example is 60 °.The tread length of side of described stainless steel unequal angle 2 is 50mm, and the riser length of side is 25mm, and thickness is 3mm.
Before precast stair concreting, by anti-skidding corner protector left-hand thread in stair punching block, and fixation, do not loosen when guaranteeing concreting.
The utility model is than traditional plastic protective angle bead, reinforcement protection bar; improve the intensity of stair step in essence; have protection domain greatly, not corrosion, use resistance to advantage of waiting so long; protection corner for stair step and staircase structure are tightly fitted simultaneously; therefore the external corner of stair step becomes not only straight but also attractive in appearance; thus form smoothly clean and tidy stair step external corner, improve the aesthetic measure of stair.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
