Technical Field
The utility model belongs to the technical field of the building is wall spare even, more specifically says, in particular to outer scaffold of instrument formula is wall spare even.
Background
The wall connecting piece is an important component for building the scaffold, and the safety is very important. In order to implement the policy of national safety production in scaffold design and construction, ensure personnel safety, and achieve advanced technology, economy, reasonability and safety application, section 6.4 of the safety technical specification of fastener-type steel pipe scaffolds for building construction (JGJ 130 plus 2011) makes clear rules on the setting requirements of wall connecting pieces, but does not have specific requirements on detailed procedures, and needs construction units to deepen scaffold erection timing.
At present, the common method is to pre-embed phi 48 vertical short steel pipes in boundary beams and then to form rigid wall connecting pieces by fastening right-angle fasteners and horizontal wall connecting steel pipes. However, this practice has found three major disadvantages: firstly, most of the pre-buried steel pipes in the boundary beam are positioned at the position of an outer wall masonry, and are generally processed by a hole-reserving post-mending method, so that the quality is not easy to control, and the outer wall is easy to leak; secondly, the embedded steel pipe cannot be reused, so that the loss is large and the cost is high; thirdly, fire operation is needed when the device is disassembled.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an instrument formula outer scaffolding is wall spare even in order to solve above-mentioned problem.
The utility model discloses a realize like this:
a tool type external scaffold wall connecting piece comprises a T-shaped connecting component, wherein the T-shaped connecting component is formed by welding two sections of steel pipes, a connecting steel plate is welded at the bottom end of the T-shaped connecting component, two bolt holes with symmetrical positions are formed in the connecting steel plate, and a hexagon bolt is arranged in each bolt hole; a hexagonal nut is arranged at one end of the hexagonal bolt close to the bolt head; the U-shaped steel ring and the two lengthened nuts are embedded in the building boundary beam, the two lengthened nuts are welded and connected to two ends of the U-shaped steel ring, and the outer ends of the lengthened nuts are flush with the building boundary beam to enable nut holes of the lengthened nuts to be exposed outwards; and the screw rod of the hexagonal bolt penetrates into the lengthened nut to connect the T-shaped connecting member with the building boundary beam.
When the building edge beam is assembled, the connecting steel plate is overlapped with the building edge beam, the bolt holes in the connecting steel plate are overlapped with the nut holes of the lengthened nuts, and the connecting steel plate is clamped and fastened by the hexagonal nuts and the lengthened nuts from two sides.
Further, a washer is arranged between the hexagonal nut and the bolt head of the hexagonal bolt.
Furthermore, the bolt hole is in a straight long groove structure with two semicircular ends.
Compared with the prior art, the utility model discloses following beneficial effect has:
firstly, the utility model discloses in, except pre-buried extension nut, other accessory that construct all adopt the instrument formula to construct the accessory, are convenient for install and remove, can effectively improve turnover rate, reduce the loss, reduce engineering cost. Secondly, the wall connecting piece adopts a side vertical face connecting mode of side beams (columns and shear walls), avoids masonry construction parts, and avoids wall leakage quality common faults caused by hole patching operation quality problems. Moreover, the utility model discloses still have construction convenience, efficient, stability is good, bear the weight of advantages such as dynamic height. When in use, the fire-fighting protection device does not need to cut structural parts on site, avoids fire operation, reduces fire-fighting risks and is worthy of popularization.
