Description
Technical field
The utility model relates to a kind of concrete curing device in the maintenance initial stage, relates in particular to a kind of detachable apparatus of protecting stair step.
Background technology
Stair are one of projects of the most often using in building, and stair step adopts a lot of of cement sand plaster, because finished product protection in work progress is improper or in use because of the collision of people or thing, the phenomenon that causes stair step to damage happens occasionally.Particularity due to staircase structure, when constructing, conventionally the structures such as concrete beam plate of first constructing, rear construction stair, therefore need to be before stair reach some strength stair activity or set up separately stair, both affected construction speed, strengthened again artificial and material cost, also likely stair are caused to damage, occur that stair step lacks the situations such as footprint of water chestnut arrisdefect, hollow.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of detachable apparatus of protecting stair step, is convenient to stair step maintenance, does not destroy concrete surface, realizes while both having made floorslab concrete not reach people's intensity, and stair also can be gone up people.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of detachable apparatus of protecting stair step; comprise step plate, junction plate, brace summer, suspension ring; step plate both sides are fixedly connected with brace summer; brace summer two ends are welded with junction plate; junction plate is provided with installing hole; between two or more brace summers, by junction plate, be fixedly connected with securing member, suspension ring are fixed on brace summer, and described step plate is portal structures.
Be arranged on the brace summer of end and junction plate angulation α=45 °～80 °.
Described step plate both sides and brace summer are bolted to connection.
Described step plate is provided with anti-skidding ripple.
Be arranged on the step plate of support beam end and be connected with the fixed head with dowel.
Compared with prior art, the beneficial effects of the utility model are:
Simple in structure, convenient installation, with bolts realization detachably, can reuse, and by suspension ring, can conveniently transport, and accelerating construction progress, is made by steel plate and channel-section steel, and rigidity is large, durable in use, the life-span is long.During construction, can bear certain equipment impact and personnel and trample.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the front view of fixed head.
Fig. 3 is the top view of fixed head.
In figure: the 1-brace summer 2-step plate 3-bolt 4-junction plate 5-platform 6-fixed head 7-dowel of walking unhurriedly.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1; a kind of detachable apparatus of protecting stair step; comprise step plate 2, junction plate 4, brace summer 1, suspension ring; step plate 2 both sides are fixedly connected with brace summer 1; brace summer 1 two ends are welded with junction plate 4, and junction plate 4 is provided with installing hole, between two or more brace summers 1, by junction plate 4, are fixedly connected with securing member; suspension ring are fixed on brace summer 1, and described step plate 2 is portal structures.The brace summer 1 that is arranged on end and junction plate 4 angulation α=45 °～80 °.Step plate 2 both sides are fixedly connected with by bolt 3 with brace summer 1.Step plate 2 is provided with anti-skidding ripple.Be arranged on the step plate 2 of brace summer 1 end and be connected with the fixed head 6 with dowel 7.
Embodiment:
Steel plate stair are made:
1,, according to plan, select long 1 meter of 15# channel-section steel, every 250mm prepared screw-bolt hole on channel-section steel.Channel-section steel two ends welding 10mm steel plate, as junction plate 4, is reserved 2 place's bolts hole on steel plate, for the connection between channel-section steel, more than two or two channel-section steels are connected successively, form the main part of detachable apparatus.
2, the steel plate member of making door shape with the thick checkered steel plate of 6mm is as step plate 2, and length is got by the length gauge of marking time, at step plate 2 both sides prepared screw-bolt holes.
3, bevel is done in two channel-section steel one end that length is respectively 500mm and 300mm, at place, channel-section steel oblique angle welding 10mm steel plate prepared screw-bolt hole, as the junction plate 4 with channel-section steel described in step 1, junction plate 4 is angle of bevel with the angle [alpha] of channel-section steel, and connect step plate 2, two channel-section steels are connected to channel-section steel two ends described in step 1, and all channel-section steels after connection form brace summers 1.
4, on channel-section steel, weld iron suspension ring, as lifting handle.
5, brush protective paint is coated with.
The steel plate stair of making are placed on the stair that laid, the step plate 2(that the is arranged on mouth top platform 5 of walking unhurriedly) on, 4 fixed heads 6 have been bolted, on fixed head 6, be welded with 150mm dowel 7, the 50mm of dowel 7 is on the ground pre-buried, sees Fig. 2, Fig. 3.
The utility model is simple in structure, convenient installation, and with bolts realization detachably, can reuse, and by suspension ring, can conveniently transport, and accelerating construction progress, is made by steel plate and channel-section steel, and rigidity is large, durable in use, the life-span is long.During construction, can bear certain equipment impact and personnel and trample.
