Description
Technical field
The present invention relates to a kind of building engineering construction technique, more particularly to a kind of tool-type wall-connecting piece and its construction technology.
Background technology
Wall-connecting piece, using generally, is applied to external scaffolding, console mode discharging platform and main body more in building engineering construction
The drawknot of structure.The main purpose that wall-connecting piece is set be ensure outrigger and expect platform monolithic stability, prevent its wind load or its
He topples under horizontal loading.According to《Construction fastener type steel pipe scaffold technical specification of security》(JGJ 130-
2011), the arrangement of wall-connecting piece should meet following requirement：
1, should be arranged close to host node, the distance for deviateing host node should not exceed 300mm；
2, it should be started setting up from the first step longitudinal horizontal rod of bottom；
3, preferentially diamond shape should be used to arrange, or uses rectangular, rectangular arrangement；
4, the both ends of open-type scaffold must be provided with wall-connecting piece, and the vertical interval of wall-connecting piece should not exceed the layer of building
Height, and should not exceed 4m；
5, wall-connecting piece should be in horizontally disposed, should be oblique to scaffold one end when that cannot be horizontally disposed with；
6, wall-connecting piece, which must use, can bear pulling force and the construction of pressure.To the double-pole scaffold of height 24m or more, Ying Cai
It is connect with building with rigid connecting tube；
7, the spacing of wall-connecting piece setting should also conform to the regulation of following table in addition to meeting and calculating requirement：
The maximum spacing of wall-connecting piece arrangement
| Erection method | Highly | Vertical spacing (h) | Level interval (la) | Every wall-connecting piece area coverage (m2) |
| Double landing | ≤50m | 3h | 3la | ≤40 |
| Double overhanging | ＞ 50m | 2h | 3la | ≤27 |
| It is single | ≤24m | 3h | 3la | ≤40 |
Note：H-step pitch；la- advance
Wall-connecting piece that existing mainstream uses and its there are the problem of it is as follows：
There are many way of present wall-connecting piece, and many companies are proposed the way of Novel wall connector, but all fail generally to push away
Extensively.The wall-connecting piece that mainstream uses at present is still traditional form, is first embedded in 10 top of beam, horizontal round steel using vertical round steel pipe 9
11 both ends of pipe wall-connecting piece are connect with pre-buried vertical round steel pipe and upright bar respectively by fastener 12.
Using above-mentioned traditional wall-connecting piece way, there are the problem of it is as follows：
1, wall-connecting piece is connected by fastener, resists horizontal loading using fastener frictional force, bearing capacity is limited.When building is high
When spending that larger, wind action power is larger, it is difficult to meet the requirements that fastener resisting slipping, which is moved and calculated,；
2, basis《Construction fastener type steel pipe scaffold technical specification of security》(JGJ130-2011), external scaffolding one
As step pitch be 1.8m, and it is more to build floor height situation, and wall-connecting piece setting is in flooring position, it is difficult to ensure that wall-connecting piece and the main section of outrigger
Point distance is not more than 300mm；
3, vertical steel pipe is embedded in top surface of the beam in advance, and in outer-wall building, this part need to be stayed and set hole, after scaffold dismounting, needs
Hole is blocked, construction trouble, and waterproof quality is relatively difficult to guarantee at hole, there are hidden leakage defects；
4, vertical steel pipe uses pre-buried form, when dismounting that can only cut steel pipe, the steel in Transducers Embedded in Concrete agent structure
Pipe can not utilize again, cause a degree of waste.
Invention content
In order to make up the above deficiency, the present invention provides a kind of tool-type wall-connecting piece and its construction technology, which connects
Wall part and its construction technology are applied widely, and outrigger is safe, easy for construction, can effectively avoid building staying for hole by laying bricks or stones and set,
Substantially increase the dismounting efficiency and recycling number of wall-connecting piece.
The present invention in order to solve its technical problem used by technical solution be：A kind of tool-type wall-connecting piece, including it is pre-buried
Reinforcing bar, transverse connection and upright bar connector, described embedded bar one end are embedded in advance in concrete main body structure, and embedded bar is another
The outside of concrete main body texture edge is stretched out in one end, and transverse connection one end is fixedly connected with the embedded bar other end, laterally
The connector other end can be fixedly connected with outrigger upright bar by what upright bar connector can be dismantled.
As a further improvement on the present invention, the embedded bar is located at the formation bending of one end in concrete main body structure
