Abstract
The utility model relates to a clamping-groove-type fixing device for H-section steel of a cantilever. The fixing device for the H-section steel of the cantilever aims to solve the problems of rot and corrosion existing in an H-section steel fixing method and reduce economic cost. According to the technical scheme, the fixing device for the H-section steel of the cantilever comprises two anchor bolt bars, a clamping groove plate and two nuts, wherein external threads matched with the nuts are arranged on the upper portions of the anchor bolt bars, through holes for the anchor bolt bars to penetrate are formed in the clamping groove plate, and the two nuts are jointly used for screwing the clamping groove plate to the two anchor bolt nuts. The fixing device for the H-section steel of the cantilever has the advantage of making construction standardized; meanwhile, the novel assembled fixing device for the H-section steel of the cantilever has a large application range and can be used for embedding 10#-32# H-section steel in an outer scaffold at the same time.
Description
Technical field
The utility model relates to a kind of card slot type suspension scaffold i iron fastening devices.
Background technology
Construction work external scaffolding is setting up in process, and Super High, highrise building, by the requirement of external scaffolding scheme, need carry out overhanging scaffold erection conventionally, therefore carrying out in suspension scaffold before i iron is set up, need to carrying out pre-buried to the i iron fixture of encorbelmenting.Conventional i iron specification is 14#～18# i iron, wherein common with 16# i iron " work 160*88*6 ", join again 2 road wide 120mm inverse u shape steel hoops and socket, and adopt the lumps of wood of size 30X40 between inverse u shape reinforcing bar and i iron, to fill reinforcing.The method itself cannot realize the standardized construction of present promotion.In the pre-buried process of reality, inverse u shape steel hoop built-in fitting is pre-buried not in place, easily causes i iron to pass, and needs again pre-buried; The erection time is long, and southern area is rainy in addition, and the lumps of wood and inverse u shape steel hoop are during pre-buried, and apt to rot and corrosion, need make regular check on and keep in repair, and indirectly increases financial cost.
Summary of the invention
The purpose of this utility model is to provide a kind of card slot type suspension scaffold i iron fastening devices, to solve the i iron fixing means of the above-mentioned apt to rot and corrosion existing, reduces financial cost.
The purpose of this utility model is achieved through the following technical solutions: a kind of card slot type suspension scaffold i iron fastening devices, and it comprises two anchor bolt bars, clamping groove plate and two nuts; The top of anchor bolt bar is provided with the external screw thread matching with described nut; On described clamping groove plate, be provided with the through hole passing for described anchor bolt bar, two nuts are jointly for being tightened on clamping groove plate on two anchor bolt bars.
Described clamping groove plate two ends are equipped with screens sheet.In use, by block board be stuck in i iron side and and the anchor bolt bar of this side between, just i iron is firmly fixed between two anchor bolt bars at the block board of i iron both sides like this.
Described screens sheet is fixedly installed on clamping groove plate.
Described screens sheet is slidably located on clamping groove plate.
Described screens sheet two ends upside is provided with the kink of inside bending.Screens sheet hangs upside down on clamping groove plate by the kink at its two ends.
Described fastening devices also comprises embedded board, and the two ends of embedded board are fixedly connected with the bottom of two anchor bolt bars respectively.Embedded board can be assisted the fixing of two anchor bolt bars.
Described nut below is also provided with pad.Pad pad between nut and anchor bolt bar, fixing for auxiliary bolt to anchor bolt bar.
Compared to prior art, the utility model has the advantage of: compare with traditional handicraft, use this Novel clamp slot type suspension scaffold i iron fastening devices, not only construction standardization, this novel fabricated card slot type suspension scaffold i iron fastening devices range of application is large simultaneously, can meet pre-buried, the especially common 16# i iron of 10#～32# i iron at external scaffolding simultaneously; Two anchor bolt bars are fixed in earth's surface by embedded board, strengthen the pre-buried stressed of whole fixture, effectively avoid plate because concentrating the stressed excessive earth's surface external crack that occurs.The utility model has also reduced outrigger operator technical difficulty simultaneously, just can construct through simple training, simple to operate, quick.
The pre-buried i iron of card slot type suspension scaffold i iron fastening devices is firm, more can guarantee that suspension scaffold entirety is safer stable, and can repeatedly reuse, convenient mounting or dismounting, the number of turnover is high, cost, realize standardized construction time, produced certain economic benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Fig. 3 is the structural representation of clamping groove plate in the utility model.
Label declaration: 1, anchor bolt bar; 2, embedded board; 3, clamping groove plate; 4, nut; 5, pad; 6, screens sheet; 7, kink; 8, i iron; 9, earth's surface; 10, through hole.
The specific embodiment
Below in conjunction with Figure of description and embodiment, the utility model content is elaborated: the embodiment schematic diagram of a kind of card slot type suspension scaffold i iron fastening devices device providing for the utility model as Figure 1-3, it comprises two anchor bolt bars 1, embedded board 2, clamping groove plate 3 and two nuts 4; The two ends of embedded board 2 are fixedly connected with the bottom of two anchor bolt bars 1 respectively, and the top of anchor bolt bar 1 is provided with the external screw thread matching with described nut 4; On described clamping groove plate 3, be provided with 10, two nuts 4 of through hole that pass for described anchor bolt bar 1 jointly for clamping groove plate 3 being tightened on to two anchor bolt bars 1.
In order to strengthen the resistance to corrosion of fastening devices, the material of above-mentioned anchor bolt bar 1, embedded board 2 and clamping groove plate 3 is stainless steel material.So package unit is difficult for being corroded, and can reuse.
In order to make i iron 8 be fixed between two anchor bolt bars 1 and be difficult for horizontally slipping, be equipped with screens sheet 6 at described clamping groove plate 3 two ends.Screens sheet 6 can directly be weldingly fixed on clamping groove plate, also can adopt slip fixing mode to be arranged on clamping groove plate 3.Slip for the ease of screens sheet 6 on clamping groove plate 3, described screens sheet 6 two ends upsides are provided with the kink 7 of inside bending.
The material of described screens sheet 6 is stainless steel.
Described nut 4 belows are also provided with pad 5.
When use, the Lower Half of two anchor bolt bars 1 is embedded in earth's surface 9 together with embedded board 2, and two anchor bolt bars 1 lay respectively at will be fixing i iron 8 both sides; Then clamping groove plate 3 is through on two anchor bolt bars 1, and is pressed in i iron 8 tops simultaneously; Then, clamping groove plate 3 is fixed on i iron 8 on two earth's surfaces 9 between anchor bolt bar 1 by nut 4 and pad 5.For i iron 8 can not be horizontally slipped between two anchor bolt bars 1, two screens sheets 6 are set in respectively on clamping groove plate 3, and allow screens sheet 6 be clipped in respectively between the both sides and two anchor bolt bars 1 of i iron 8, with supplementary card frid 3 to firm fixing of I-shaped.The thickness of screens sheet 6 can design according to the width of i iron 8, such as will be fixing i iron 8 when narrower, can not change the distance of two anchor bolt bars 1, directly be stuck between i iron 8 and anchor bolt bar 1 just with the screens sheet 6 of wider width, so just facilitate reusing of the utility model card slot type suspension scaffold i iron fastening devices.
