Abstract
The utility model discloses a kind of anti-skidding corner protector of prefabricated assembled clear water stair, comprise the angle steel being arranged on stair step external corner, described angle steel body tread offers groove, forms concavo-convex reeding; Described angle steel and anchor bar are welded to connect, and 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 can obviously improve stair step intensity and application life, saves later stage decoration and repair maintenance expense, has antiskid function again, without the need to the installation of later stage reeding simultaneously.
Description
Technical field
The utility model relates to a kind of anti-skidding 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.Along with country is to the development of the support of PC prefabricating technique and PC prefabricating technique, prefabricated assembled clear water stair are provided with good market and wide development space.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, all very easily cause the damage of the 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.Traditional prefabricated assembled clear water stair form antiskid function by arranging two grooves on tread structure simultaneously, not only attractive in appearance not, easy dust stratification in groove, and skidproof effect is poor.Currently available technology needleless not only there is antiskid function but also there is the device of corner protector function prefabricated assembled stair step.
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.Again there is antiskid function, without the need to the installation of later stage reeding simultaneously.
The technical solution of the utility model is: a kind of anti-skidding corner protector of prefabricated assembled clear water stair, is characterized in that, comprise the angle steel being arranged on stair step external corner, described angle steel body tread offers groove, forms concavo-convex reeding; Described angle steel and anchor bar are welded to connect, and described anchor bar is embedded in the concrete structure of stair in advance, and described anchor bar end makees 180 ° of curved anchors.
The anti-skidding corner protector of aforesaid a kind of prefabricated assembled clear water stair, is characterized in that, the soldering angle of described angle steel and anchor bar is 60 ° ± 10 °.
The anti-skidding 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 anti-skidding 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 anti-skidding 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 anti-skidding corner protector of aforesaid a kind of prefabricated assembled clear water stair, is characterized in that, described anchor bar is 3 ~ 6 right.
The anti-skidding 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:
1. 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.
2. the utility model offers groove on angle steel raw material, present concavo-convex, form antiskid function, novel structure, appearance looks elegant, reliable in quality, good antiskid effect, meanwhile, because being directly embedded in structure, intensity is high, the easy obscission of reeding is installed after avoiding tradition, saves later maintenance cost.
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. reeding; 4. 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, comprises the stainless steel unequal angle 2 being arranged on stair step external corner, described stainless steel unequal angle 2 body tread offers groove, forms concavo-convex reeding 3.Novel structure, appearance looks elegant, reliable in quality, good antiskid effect, meanwhile, because being directly embedded in structure, intensity is high, installs the easy obscission of reeding, save later maintenance cost after avoiding tradition.
Described stainless steel unequal angle 2 is welded to connect with anchor bar 1, and described anchor bar 1 is bar dowel (plain bar or indented bars), and 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 4 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.
