Abstract

The utility model discloses a scaffold-wall connecting component in construction, which comprises a steel pipe transversely arranged in a scaffold and bolts and nuts matched with the steel pipe, wherein the end of the steel pipe facing to a wall is fixedly connected with the bolts; the nuts are butterfly-shaped; a threaded hole positioned in the middle is a blind hole; and bent plates symmetrically expanding outward are arranged on a blind plate at the rear end of the nut. When in site operation, craft screw plugs are filled in the nuts before pre-embedding so as to prevent the nuts from being blocked by concrete in the pre-embedding. When the scaffold is set up, the craft screw plugs are detached firstly, the bolts at the steel pipe end are screwed in the target nuts, and then a fastener is used for locking the steel pipe with the scaffold, therefore, the scaffold and the wall form an integral structure by connecting wall connecting components in sequence so as to greatly improve the stability and reliability of the scaffold. The scaffold-wall connecting component is simple in structure, convenient to install and reliable in connection, and is particularly applicable to setting up high-level scaffolds.

Description

Building scaffold connects wall member

Technical field

The utility model relates to a kind of construction equipment, and particularly a kind of building scaffold connects the member of body of wall.

Background technology

Scaffold is the platform and the guardrail of constructor's ascend operation in the construction work.Current era, the scaffold of using in the construction work generally is barricaded as with steel pipe and fastener, and whether the scaffold of this frame construction reliably is directly connected to constructor's life security.In the engineering in order to increase the reliability of steel pipe scaffold, usually with scaffold be connected building body of wall, company's wall construction of prior art is to put the steel pipe that stretches within the walls at interval to connect pre-pile anchoring on the flooring in scaffold, make scaffold become one with the building that leans on mutually, this structure significantly increases the stability of scaffold, thereby promotes reliability.But also there is shortcoming in this structure, at first is that steel pipe is passed in the body of wall of building, and pre-pile anchoring all hinders follow-up construction on the flooring.Next is that the naked light of generation easily constitutes the potential safety hazard of job site when slicing off on the flooring pre-pile anchoring the engineering later stage, and there is the defect of seepage in the filling-up hole place on the body of wall.

The utility model content

The utility model is primarily aimed at the deficiencies in the prior art, propose a kind of simple in structure, make easy, easy for installation, connect reliably, neither hinder follow-up construction, do not have the building scaffold of work with torches to connect wall member yet.

The utility model is achieved through the following technical solutions technical goal.

Building scaffold connects wall member, and it is made of steel pipe horizontal in the scaffold and the bolt, the nut that match.Its improvements are: described steel pipe is in the face of an end axial restraint connecting bolt of body of wall.Described nut is butterfly, and the M16mm～25mm screwed hole in the middle of being positioned at is a blind hole, and the nut back end blind plate is provided with the outer bent plate that launches of symmetry, and both sides bent plate abduction total length is greater than 1～2 times of diameter of steel tube, the wide 30mm～50mm of bent plate, thick 1.5mm～3mm.

In the said structure, the bent plate of nut back end is quarter bend or arc bend member.

The utility model compared with prior art has following benefit:

1, even wall construction is simple, easy to manufacture, easy for installation, connection is reliable;

2, the outer installation of wall does not hinder follow-up construction, improves construction environment greatly;

3, the installation site does not need hole to be provided, need not filling-up hole after the dismounting, does not have the body of wall hidden leakage defect;

4, the pre-pile anchoring that does not expose on the flooring is saved and is cut off operation afterwards, so there is not the condition of initiation fire.

The specific embodiment

Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.

Building scaffold shown in the accompanying drawing 1 connects wall member, and it is made of steel pipe horizontal in the scaffold 1 and the bolt 2, the nut 3 that match.Described steel pipe 1 is in the face of an end axial restraint connecting bolt 2 of body of wall, and bolt 2 is M25mm in the present embodiment.In the middle of the screwed hole of described nut 3 was positioned at, screwed hole was a blind hole, and nut 3 rear end blind plates 3.1 are provided with the outer bent plate 3.2 that launches of symmetry, and the bent plate 3.2 in the present embodiment is the quarter bend member, and bent plate 3.2 abduction total lengths in both sides are 60mm, wide 45mm, thick 2mm.Nut 3 is embedded in the concrete by desired location.

During site operation, flow in the screwed hole in order to prevent nut 3 concrete when pre-buried, plug is adorned the technology plug screw in the screw of nut 3 in advance, and the screwed hole of nut 3 flushes outwardly and with concrete edge when laying.Lay down the technology plug screw when scaffolding erecting earlier, an end that then steel pipe 1 is provided with bolt 2 nut 3 that aims at the mark screws, then with fastener with steel pipe 1 and scaffold locking.The utility model is linked in sequence by the above-mentioned wall member that connects, and makes scaffold and body of wall become an overall structure, strengthens the stability of scaffold greatly, thereby significantly improves the reliability of scaffold.
