Abstract
The utility model relates to a protective railing for an edge of a floor, in particular to a sleeve type protective railing fastening part for the edge hole of the floor, and aims to solve problems that regular maintenance and labor consumption are large when the protective railing is in use, rental amount of steel tubes is large, and appearance effect is bad. The sleeve type protective railing fastening part for the edge hole of the floor comprises flat iron, a steel tube, a single-end bolt and expansion bolts. The steel tube is welded on the flat iron. Two expansion bolt holes are formed at two ends of the flat iron. A small hole is formed in the center of the steel tube. The single-end bolt is screwed in the small hole. The sleeve type protective railing fastening part for the edge hole of the floor has the advantages of not only being easy to manufacture and convenient to repair, but also lowering construction cost and cleaning construction environment.
Description
Technical field
The utility model relates to the floor edge guard rail, particularly the telescopic guard rail fastener in a kind of floor edge hole.
Background technology
Steel tube fastener formula guard rail is all adopted in general floor protection, and this railing is mainly by horizon bar, and vertical rod and diagonal brace three parts consist of.Although this guard rail can effectively solve floor edge hole security protection problem, has periodic maintenance, steel pipe rent with the problem of the many and overall appearance weak effect of quantity.Thereby cause construction cost higher, construction environment is more random.
Summary of the invention
The utility model is many in order to solve guard rail periodic maintenance recruitment in the middle of using, and steel pipe is rented high with quantity, the problem that appearance effect is poor.Thereby provide a kind of floor edge hole telescopic guard rail fastener.
For addressing the above problem, the utility model adopts following technical scheme: the telescopic guard rail fastener in floor edge hole, comprise band iron, steel pipe, single ended bolt and expansion bolt, steel-pipe welding is on band iron, the band iron two ends are equipped with two hole for the expansion bolts, be screwed with expansion bolt on the hole for the expansion bolt, the center of steel pipe is equipped with eye, is screwed with single ended bolt in the eye.
In the telescopic guard rail fastener in described floor edge hole, band iron becomes 90 ° of vertical weldings with steel pipe.
The concrete using method of fastener of the present utility model is as follows: eject 50 lines in both sides, building hole, 45mm on line, 155mm, 645mm, the respectively perforating of 755mm place.Telescopic guard rail fastener is fixed on both sides, building hole by Φ 8 expansion bolts.Select suitable steel pipe to penetrate in the fastener as horizon bar according to width of cave entrance, tighten fastening bolt.When the building hole was long, the vertical rod that then arranges in the hole was used for the fixed level bar.
The relative prior art of the utility model has following beneficial effect: 1. fastener comprises band iron, steel pipe, single ended bolt and expansion bolt, makes simply, is convenient to repair.2. after using above-mentioned guard rail fastener, saved the diagonal brace part, thereby reduced the use of steel pipe, reduced cost, it is cleaner and tidier that the job site environment becomes.3. the utility model is with fastener horizon bar to be fixed on the building walls, support more firm and durable in use, so the maintenance less hard.

The specific embodiment
Such as Fig. 1, shown in 2, the fastener of sleeve guard rail comprises a block length 150mm, wide 50mm, the Φ 60*3 steel pipe 2 of 1, long 100mm of band iron of thick 5mm, and filament length 30mm, the single ended bolt 4 of diameter 12mm.Steel pipe 2 is vertically welded in the centre of band iron 1, band iron 1 two ends are equipped with the hole for the expansion bolt 3 of two diameter 10mm apart from 20mm place, band iron 1 edge, be screwed with expansion bolt 6 on the hole for the expansion bolt 3, steel pipe 2 center perforating mantle fibers, be screwed with the long 30mm of a rhizoid, the single ended bolt 4 of diameter 12mm.
The sleeve guard rail overall schematic of installation as shown in Figure 3.50 lines are ejected in both sides, building hole, 45mm on the line, 155mm, 645mm, the respectively perforating of 755mm place.Φ 8 expansion bolts 6 are fixed on both sides, building hole with fastener.Horizon bar 5 is through in the fastener, tightens single ended bolt 4, and the fixed level bar prevents the horizon bar move left and right.If the building hole is long, then in the hole, place vertical rod 7, be used for fixing and be connected horizon bar 5.
