Abstract
The utility model discloses a stair blank, its technical scheme main points include a plurality of steps, the outer dog -ear department of step installs the guard plate, the guard plate is the outer dog -ear department of L type joint in the step, the both ends of guard plate are connected with the baffle, baffle fixed connection is in the lateral wall at step both ends. An object of the utility model is to provide a stair blank can prevent effectively that the outer dog -ear of stair from producing damagedly in the construction use.
Description
Technical field
This utility model relates to building structure, and more specifically it relates to a kind of stair blank.
Background technology
Known, existing building stair are reinforced concrete structure, building also needs to carry out the finishing of indoor and outdoor after building up, fitment process requires over stair transport material, such as reinforcing bar, tubing etc., owing to the outer knuckle place of concrete staircase is relatively fragile, workman drags the operation such as reinforcing bar, tubing along stair and is extremely easily caused stair outer knuckle place breakage, although again breakage can be repaired after substantially having fitted up, but poor by the part globality after repairing, and intensity is more weak.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is in that to provide a kind of stair blank, it is possible to effectively prevent the outer knuckle of stair from producing breakage in construction usage process.
For achieving the above object, this utility model provides following technical scheme: a kind of stair blank, including some steps, the outer knuckle place of described step is provided with protective plate, the L-shaped outer knuckle place being connected in step of described protective plate, the two ends of described protective plate are connected to baffle plate, and described baffle plate is fixedly connected on the sidewall at step two ends.
Effect of the present utility model is in that, the protective plate of setting is for being connected to the outer knuckle place of step, and is connected with the sidewall at step two ends by the baffle plate arranged, and baffle plate is connected with protective plate, thus protective plate is fixed on the outer knuckle place of step. By adopting such scheme, the outer knuckle place that can be prevented effectively from fitment process due to the operation such as dilatory material to cause step is damaged, is dismantled by protective plate, finally fit up this stair blank after finishing completes. And protective plate and baffle plate can recycle, save cost.
This utility model is further arranged to: described protective plate and baffle plate are engineering plastics material.
By adopting technique scheme, engineering plastics have high-wearing feature, are hardly damaged, convenient recycling, and the convenient processing of engineering plastics, it is possible to the protective plate of L-type is passed through injection moulding integrated molding.
This utility model is further arranged to: described baffle plate is secured by bolts in protective plate.
By adopting technique scheme, the installation and removal between more convenient baffle plate and protective plate.
This utility model is further arranged to: the reinforcing bar that the reserved projection of the sidewall of described step is arranged, described baffle plate is provided with the through hole for being set on reinforcing bar.
By adopting technique scheme, this reinforcing bar, for coordinating, with the through hole on baffle plate, the installation facilitating baffle plate, is clipped by the sidewall reserved steel bar at step two ends when the later stage fits up stair.
This utility model is further arranged to: described protective plate surface is provided with anti-slip veins.
By adopting technique scheme, the anti-slip veins of setting makes this stair blank have better non-skid property.
In sum, this practicality provides a kind of blank that can effectively prevent the outer knuckle of stair damaged in construction usage process.
Accompanying drawing explanation
Fig. 1 is the structural representation of stair blank described in the present embodiment;
Fig. 2 is the part A enlarged drawing of Fig. 1.
Description of reference numerals: 1, step; 2, protective plate; 3, baffle plate; 11, reinforcing bar; 21, anti-slip veins; 22, bolt.
Detailed description of the invention
Referring to figs. 1 through Fig. 2, this utility model embodiment is described further.
Stair blank described in the present embodiment, as shown in Figure 1, including some steps 1, the outer knuckle place of described step 1 is provided with protective plate 2, the L-shaped outer knuckle clamping with step 1 of described protective plate 2, the two ends of described protective plate 2 are connected to baffle plate 3, and described baffle plate 3 is fixedly connected on the sidewall at step 1 two ends.
Preferably, described protective plate 2 and baffle plate 3 are engineering plastics material. Engineering plastics have high-wearing feature, are hardly damaged, convenient recycling, and the convenient processing of engineering plastics, it is possible to the protective plate 2 of L-type is passed through injection moulding integrated molding.
As in figure 2 it is shown, described baffle plate 3 is fixed on protective plate 2 by bolt 22, facilitate the installation and removal of baffle plate 3.
As in figure 2 it is shown, the reinforcing bar 11 that the reserved projection of the sidewall of described step 1 is arranged, described baffle plate 3 is provided with for being set in the through hole on reinforcing bar 11. This reinforcing bar 11, for coordinating, with the through hole on baffle plate 3, the installation facilitating baffle plate 3, is clipped by the sidewall reserved steel bar 11 at step 1 two ends when the later stage fits up stair. Certainly above-mentioned a kind of preferred version that simply baffle plate 3 is connected with step 1 sidewall, it is possible to adopt at step 1 side-wall hole, connected by the mode of securing member fixed dam 3.
Effect of the present utility model is in that, the protective plate 2 of setting is for being connected to the outer knuckle place of step 1, and is connected with the sidewall at step 1 two ends by the baffle plate 3 arranged, and baffle plate 3 is connected with protective plate 2, thus protective plate 2 is fixed on the outer knuckle place of step 1. By adopting such scheme, the outer knuckle place that can be prevented effectively from fitment process due to the operation such as dilatory material to cause step 1 is damaged, is dismantled by protective plate 2, finally fit up this stair blank after finishing completes. And protective plate 2 and baffle plate 3 can recycle, save cost. Preferably, described protective plate 2 surface is provided with anti-slip veins 21, and the anti-slip veins 21 of setting makes this stair blank have better non-skid property.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, all within design concept of the present utility model, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
