Abstract

The utility model discloses a wall connection structure of a scaffold, wherein a tie bar is formed by a bolt which is tensed by an end part nut and passes through a whole split bolt hole way and a whole rail; and a back shore is formed by the rail which is butted with the split bolt hole way and is supported on a wall body under the limitation of the tensed bolt. According to the wall connection structure disclosed by the utility model, the tie bar and the back shore are integrally combined skillfully, and the bar tying and the supporting can be finished for one step in a way that the bolt passes through the hole way and the end part nut is screwed in, so that the reliable connection of the scaffold and the wall body is realized, operation is simple, convenient and quick, labor strength is low, and construction time is short; meanwhile, the back shore directly utilizes the rail of the scaffold and is not additionally mounted, so that cost is reduced; and furthermore, after the construction is finished, the bolts can be directly detached, so that the attractive appearance of the wall body is not influenced.

Description

A kind of scaffold connecting structure

Technical field

When the utility model relates to wall construction in order to connect company's wall construction of scaffold and body of wall.

Background technology

During wall construction, during especially high wall construction, scaffold need use wall-connecting piece to be connected with the body of wall wall, to improve stability and the supporting capacity of scaffold; Avoid scaffold accident such as topple over, cave in to take place, make scaffold safer.

Stipulate according to " building operations fastener type steel pipe scaffold technical specification of security " JGJ130-2001: to the single, double row scaffold of height below 24m, should adopt the rigidity wall-connecting piece reliably to be connected with building, also can adopt lacing wire and shore the attached wall connected mode that is used.

Rigidity wall-connecting piece form, as Fig. 1, the surface of its clear-water concrete body of wall is provided with anchor slab 2 pre-buried when constructing, and an end of rigidity wall-connecting piece 3 is welded on the anchor slab 2, and the other end adopts fastener to be connected with scaffold.This kind structure needs welding during installation, need cutting during dismounting, and work progress comparatively bothers; And the anchor slab that is embedded in surface of wall can influence the outward appearance of body of wall, particularly has the anchor slab of scar after welding and cutting, can influence the attractive in appearance of body of wall greatly.

Lacing wire and shore the attached wall connected mode that is used, as Fig. 2, the template split bolt duct of leaving over when it utilizes clear-water concrete wall body structure forming construction 4, round steel or steel wire 5 pass this duct, one end is anchored on the clear-water concrete body of wall, the other end and scaffold buckle drawknot, form lacing wire; And in the position of lacing wire, telescopic rigidity steel member 6 is set, and steel member one end and scaffold adopt fastener to be connected and fixed, and the other end is shored on the clear-water concrete body of wall, and formation is shored.This kind structure can not influence the attractive in appearance of body of wall, but construction sequence is comparatively numerous and diverse, and labour intensity is bigger, and installation procedure is also more, comparatively consuming time simultaneously, can influence construction speed.

The utility model content

The utility model aims to provide a kind of exterior appearance that can not influence the clear-water concrete body of wall, and scaffold connecting structure easy and simple to handle.

Scaffold connecting structure described in the utility model, the rigidity pipe fitting that its scaffold setting is docked with the split bolt duct that wall construction is left over is as cross bar, the end of cross bar is provided with end casing, the port of cross bar and metope joint is provided with the pressure wallboard greater than the cross bar bore, bolt runs through whole split bolt duct and whole cross bar simultaneously, compresses by nut in the end.

Scaffold connecting structure described in the utility model, it forms lacing wire by the bolt that runs through whole split bolt duct and whole cross bar of end nut tension; By the cross bar that docks with the split bolt duct, under the restriction of the bolt of straining, be supported on the body of wall, formation is shored; It is dexterously with lacing wire with shore and be combined into one, and screws nut and gets final product a step and finish lacing wire and support by wearing bolt and end, realizes that scaffold is connected with the reliable of body of wall, and is simple, convenient, quick, labour intensity is low, the time of construction lacks.Simultaneously, shore the cross bar that directly utilizes scaffold, do not need extra setting, also reduced cost.In addition, after construction finished, bolt can directly be dismantled, and also can not influence the outward appearance of body of wall.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

Shown in Fig. 5-7, the cross bar 8 of scaffold is rigidity pipe fitting 7, the position in the split bolt duct of leaving over when the pore of cross bar 8 is constructed with body of wall 14 is relative, cross bar 8 and split bolt duct 4 close butt joints with scaffold, use bolt 10 to penetrate split bolt duct 4 from the body of wall opposite side, behind the cross bar 8 that runs through whole split bolt duct 4 and dock with it, penetrate from the pressure wallboard 17 of cross bar 8 with the metope joint earlier, end casing 9 from the tail end of cross bar 8 passes again, screwing on nut 11 again is pressed on the end casing 9, and scaffold is pressed on the body of wall wall by cross bar, the realization scaffold is connected with body of wall.

Bolt 10 can adopt plain bolt,, perhaps adds the large-area pressure wallboard 17 that places between bolt head and the wall and fixes with metope by fixing by head and metope at relative scaffold opposite side.Bolt 10 also can adopt split bolt, screws with metope by nut equally at relative scaffold opposite side and fixes, and large-area pressure wallboard 17 can be set between nut and wall equally fix with metope, as Fig. 6.

Cross bar and body of wall contact jaw can arrange large-area pressure wallboard 17 equally, press the contact area of wallboard and body of wall wall greater than the cross bar bore, by pressing wallboard directly to contact with wall, thus the contact area of increase cross bar and body of wall wall, the steadiness that is connected with body of wall with further raising scaffold.Press wallboard can only place between cross bar and wall, also can directly be fixed on crossbar end by modes such as welding.Described pressure wallboard 17 can be circle, square, triangle, hexagon or other shape.

Fig. 3-4, if body of wall 1 both sides all need arrange scaffold, then the cross bar 8 of both sides scaffold can be docked with the two ends in split bolt duct 4 are close respectively, bolt 10 penetrates from the end casing 9 of the cross bar 8 of the scaffold of body of wall one side, pass from the pressure wallboard 17 of cross bar 8 with the metope joint again, behind the pressure wallboard 17 and cross bar 8 of split bolt duct 4 and opposite side, pass from the end casing 9 of the cross bar 8 of the scaffold of opposite side, screw on nut 11 again is pressed on the end casing 9 at the two ends of bolt 10, the scaffold that makes two ends is firm being pressed on the body of wall together, realize being connected of both sides scaffold and body of wall simultaneously, set up vertical equity bar 12 at cross bar 8 then, vertical rod 13 and transverse horizontal bar 14 form scaffold.
