Abstract
The invention relates to a safe and practical tread board for realizing the simple and convenient disassembly and assembly of a temporary staircase in a construction site, comprising a tread steel board and steel tube rings, wherein the outer side of the tread steel board is turned downwards, the inner side of the tread steel board is turned upwards, and one steel tube ring used for penetrating in a tread steel tube is welded at each of the both sides of the back surface of the tread steel board respectively. The tread steel board is a steel board with patterns which are 3 mm thick, as well as is 900 mm long and 250 mm wide. The inner side and the outer side of the tread steel board are turned upwards by 30 mm and turned downwards by 30 mm respectively. The two steel tube rings on the back surface of the steel board have a diameter of 50 mm. According to the invention, the tread steel board which is convenient to disassemble and assemble is additionally arranged on the basis of the original temporary staircase which is erected by all-steel tubes, thus overcoming the defect that the original tread steel board composed of double steel tubes is bad in anti-slide force and extremely easy to cause safety accidents. Except the tread steel board, the whole temporary staircase structure can be formed by standard scaffold steel tubes and fasteners, and is simple and convenient to erect.
Description
Technical field
The interim stair that the construction of a kind of building site of the present invention is set up, especially a kind of flexible form of setting up is applicable to the step plate of the interim stair of each construction stages such as on-the-spot excavation of foundation pit, structure construction.
Background technology
In the present building construction process, the interim stair of setting up in each construction stage such as during the excavation of foundation pit, during the structure construction are seen everywhere, service time, extremely short major part adopted bamboo staircase, wooden staircase etc., service time is long then adopts stair when being set up clamping plate that the interim stair that form or timber sets up and faced by all-steel-pipe, also has the interim stair of section steel manufacture etc.And the interim stair of above-mentioned various construction respectively have its pluses and minuses: bamboo staircase, wooden staircase are applicable to the extremely short and little occasion of the discrepancy in elevation of operating period, and bearing capacity is little, generally is used for a small amount of librarian use, and safety is relatively poor, holds easy to fall down; The interim stair that adopt timber to set up, outward appearance is cleaner and tidier, but makes slowly, and dismounting inconvenience is difficult for recyclingly, consumes not environmental protection of timber, is applicable to only need do two, three, four occasions of marking time; By the stair of section steel manufacture, need to be unfavorable for reusing for the installation site customization, expense is larger; Existing job site is commonly by the interim stair of all-steel-pipe fastener assembly unit, what mainly adopt is the common scaffold tubes in job site, setting up angle can set up according to actual needs with height, set up flexibly, easy accessibility, but adopt two round steel pipe to form because it is marked time, skid resistance is relatively poor, particularly under the wet environment, cause easily user of service's falling accident that slips, safety has much room for improvement.
Summary of the invention
The present invention will provide a kind of easy and safe and practical step plate of the interim stair dismounting in job site of realizing, this step plate is the standard block plate, in conjunction with the interim stair of the common all-steel-pipe in job site, but be combined into the simple and easy construction stair with complete tread, mounting or dismounting are convenient, set up step number and angle is flexible, and step plate adopts checkered steel plate to make, and has preferably antiskid effect, makes things convenient for about the workman, safety is guaranteed, and greatly facilitates on-the-spot construction.
Technical scheme of the present invention is: a kind of easy and safe and practical step plate of the interim stair dismounting in job site of realizing, comprise the steel plate of marking time, the steel pipe ring, the steel plate lateral lower hem of marking time, the steel plate inboard of marking time is upward folded, and the both sides, the steel plate back side of marking time are welded with respectively a steel pipe ring that is used for penetrating the steel pipe of marking time.
The steel plate of marking time is the thick checkered steel plate of 3mm, and length is 900mm, the wide 250mm of tread.
The steel plate medial and lateral of marking time are rolled over respectively the 30mm limit up and down.
The diameter of two the steel pipe rings in the steel plate back side of marking time is 50mm.
The invention has the beneficial effects as follows:
The present invention sets up simple load and unload step plate on the basis of the interim stair that original all-steel-pipe is set up, and the skid resistance of marking time that has overcome former pair of steel pipe composition is poor, very easily causes the shortcoming of security incident.Whole interim staircase structure all can adopt standard steel pipe scaffolding and fastener except step plate, set up easy.
The present invention is by being processed into step plate the standard block plate, the interim stair of setting up in conjunction with job site steel tube fastener commonly used, by simple installation combination, formation is applicable to the interim stair of the various operating modes in job site, and simple in structure, the mounting or dismounting convenient transfer, recycling rate of waterused is high, safety is good, is conducive to the standardized construction of job site.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is along the sectional view of A-A among Fig. 1;
Fig. 3 is that the present invention's interim stair that are used to construct are set up schematic diagram.
The specific embodiment
Such as Fig. 1, shown in 2, a kind of easy and safe and practical step plate of the interim stair dismounting in job site of realizing comprises the steel plate 1 of marking time, steel pipe ring 2, the steel pipe 3 of marking time, steel tube fastener 4 etc.
The steel plate 1 lateral lower hem of marking time, the steel plate inboard of marking time is upward folded, and the both sides, the steel plate back side of marking time are welded with respectively a steel pipe ring 2 that is used for penetrating the steel pipe of marking time.
The steel plate 1 of marking time adopts the thick checkered steel plate of 3mm, length is 900mm, the wide 250mm of tread, mark time and roll over 30mm under steel plate 1 lateral, 30mm is then upwards rolled in steel plate 1 inboard of marking time, respectively weld the steel pipe ring 2 of two diameter 50mm in the both sides, steel plate 1 back side of marking time, be used for penetrating the steel pipe 3 of marking time of diameter 48mm, fixing with the both sides steel pipe 3 of marking time.Originally the unit board of marking time is made simple, and is lightweight, convenient in carrying, and recycling rate of waterused is high, and is economical good.
As shown in Figure 3, step plate of the present invention is set up for the interim stair of constructing, and marking time is fixedly connected with handrail steel pipe (steel pipe 3 of marking time) by steel tube fastener 4 above the steel pipe 3.The steel plate 1 of marking time is inserted in the steel pipe 3 interior formation of marking time by steel pipe ring 2 marks time.
