Abstract

The utility model relates to an insertion built-up scaffold used in civil engineering construction. The utility model is mainly composed of a top fork, a column base, frame units, end connecting rods and attachment fittings. Each frame unit (7) is composed of a plane triangle frame. A top standpipe and one end of a bottom standpipe are crossed and are tightly sheathed with an upper pin (8) and a lower pin (9). The frame units are connected with self bolts, and therefore, the fasteners and bolts of the traditional scaffolds can be left out. The insertion built-up scaffold can be easily assembled and disassembled and can be avoided from losing fasteners and bolts. The utility model comprises a bolt (4) for the column base and a bolt (11) for the top fork on bottom and top and is provided with a regulating nut (3) and a cap nut (2) to match the bolt (4) and the bolt (11). Therefore, height of the scaffold can be slightly regulated and the regulating nut can be prevented from loosening. The insertion built-up scaffold can be easily used and can be disassembled without any tool.

Description

Insertion built-up scaffold

A kind of inserted-spliced type scaffold that relates to is used for the construction of civil works, belongs to scaffold.

In civil works,, all need to use a large amount of scaffolds no matter be building construction or bridges and culverts building.In the prior art, the scaffold of steel work uses very general, though this scaffold has the advantage of repeatedly using recovery and easy accessibility, but there are comparatively distinct issues, to use shape comparatively complicated fastener and bolt being connected between this scaffolding pole and the bar, this structure not only increases the workload of dress folding scaffold, and increases whole scaffold weight, causes construction cost to rise.Every mounting or dismounting that more inconvenient is once, fastener and bolt all will be lost much, the fastener amount lost reaches more than 20% sometimes, especially in bridge construction, fastener is lost in and generally all is difficult in the water give for change, thus the influence construction.

In view of this, the purpose of this utility model is to provide that a kind of not fastener is connected with bolt, the scaffold member stress is good, and the top of scaffold and bottom height can be made an amount of latch assembly formula scaffold of regulating.

The utility model adopts plane triangle framework single-piece, adopt the latch interconnection system of the end of pipe own between the single-piece pipe end, the diagonal brace bar is socketed on the latch, it is adjustable top fork that adjustable suspension column, scaffold top are used in the scaffold bottom, and adjustable suspension column and top fork screw rod are provided with locking locking device, by aforementioned structure and device, realize above-mentioned purpose,, in detail architectural feature of the present utility model is described in detail below in conjunction with drawings and Examples.

Referring to Fig. 1-7, the utility model is made up of five parts such as top fork, suspension column, framework single-piece, end extension bar and auxiliaries.Main member comprises: suspension column base plate (1), locking nut (2), adjusting nut (3), suspension column screw rod (4), bottom extension bar (5), hound (6), framework single-piece (7), last latch (8), following latch (9), top extension bar (10), top fork screw rod (11), top fork (12), staircase (13) constitutes.Suspension column base plate (1) is made for steel plate, its structure is referring to Fig. 4, be drilled with centre bore at the base plate center position, cooperate welding with the alignment pin of suspension column screw rod (4) bottom, the shape of suspension column base plate (1) can be square, and circular or other geometrical plane shapes can be processed several screws as required on base plate, so that be connected with basic sleeper beam, referring to Fig. 3.Locking nut (2), both structures of adjusting nut (3) are identical, and just the aspect ratio adjusting nut (3) of locking nut (2) is lower slightly, for reducing accessory and mounting or dismounting conveniently, both can make just the same, are welded with handlebar in the both sides of nut symmetry, the mounting or dismounting of being more convenient for.Suspension column screw rod (4) is a straight-bar, and top is polished rod, it and bottom extension bar (5) socket, in, the bottom is that screw thread, bottom are alignment pin and weld with base plate (1).Bottom extension bar (5) is identical with its planform of top extension bar (10), only direction difference when assembling is used.It is formed by a long tube and two short vertical tube assembly weldings.A short vertical tube is respectively welded at the two ends of long tube, wherein one is perpendicular siphunculus, for suspension column screw rod (4) or top fork screw rod (11), hound (6) and framework single-piece (7) serial connection suit, the polished rod part on screw rod (4) top is equally inserted in bottom extension bar (5) vertical tube with pin.One end of the perpendicular short tube of another root tightly puts latch (8), and last latch (8) inserts in the short vertical tube of framework single-piece (7).An end face of the vertical tube of top, end extension bar contacts with the end face of adjusting nut (3), to regulate height.

Framework single-piece (7) is the maximum important component of the utility model consumption, and it is welded into a plane triangle by four steel pipe.Leg-of-mutton top is a short tube, one end of short tube tightly is with latch so that be connected with another framework single-piece, one end of triangle base vertical tube also tightly is with down latch (9), but the direction of the direction of base latch and apex vertical tube latch is opposite, and the intersection socket, framework single-piece (7) one anti-one is just promptly pushed up the end of, and the end is assembled into the engineering scaffold of differing heights successively the end of to.Top fork (12) is arranged at the top of scaffold, top fork (12) is a flute profile, top fork (12) welds mutually with top fork screw rod (11), on screw rod (11), also be equipped with and regulate and locking nut, top fork (12) is used for supporting and the clamping back timber, be convenient on back timber, lay crossbeam and backing plate, in order to construction (referring to Fig. 3).

When the height of scaffold is higher, about the constructor, also set up staircase (13), the height and the quantity of staircase (13), needs according to scaffold are decided, if when the length of scaffold height and scaffold is very long again, can establish several staircases more, be convenient to increase work efficiency about the constructor.Hound (6) is what to be provided with for the monolithic stability that increases scaffold is qualitative, and it is respectively to be welded with circular arc hoop (referring to Fig. 7) at the two ends of a steel pipe, with the upper and lower latch socket of framework single-piece (7), becomes diagonal to connect respectively.The quantity of hound (6) is decided according to instructions for use, if the weight of scaffold carrying is big and when having lateral force to influence, can suitably increase the quantity of hound (6).

The utility model is through field trial, be applicable to the place that needs to use scaffold in all Construction of Civil Engineering, safe and reliable, mounting or dismounting are convenient, and do not need dismantling device, than now will save more than 10% with the material of scaffold on an equal basis, the also available screw rod of the height of scaffold (4) and (11) are done to regulate in a small amount, bring a lot of convenience to construction.
