Abstract
The utility model relates to a connected part for a fixed structural steel overhanging scaffold, which comprises two metal members. One ends of the metal members are provided with bending portions, end portions of the bending portions are provided with reflexed portions, and the other ends of the metal members are provided with threaded portions. A fixing plate is arranged between the threaded portions of the two metal members, and the fixing plate is in detachable connection with the metal members. When the connection part is in use, one metal member is respectively and previously embedded on two sides of structural steel. The bending portions of the metal members are previously embedded under reinforcing steel bars of floor slabs, and the upper portion of the structural steel is fixed with the threaded portions through fixing plate drill holes and nuts, thereby being simple in operation, safe, reliable and capable of avoiding imprecise contact between previously embedded U-shaped rings and the structural steel and safety hazards caused by wood wedges.
Description
Technical field
The utility model relates to a kind of connector, specifically, relates to a kind of fixedly shaped steel builder's jack and uses connector, belongs to technical field of buildings.
Background technology
Along with the fast development of highrise building, in the exterior wall scaffold construction, for guaranteeing engineering construction safety; And can reduce construction cost effectively; Usually adopt the shaped steel builder's jack, in the concrete construction, generally adopt the method for pre-buried U type ring, pre-buried dowel or embedded iron parts that shaped steel is fixed.
Pre-buried U type ring: need use timber wedge urgent or when shaped steel is installed with dowel bending and firm welding; Adopt the timber wedge jam-pack,, and have certain fastening force though method is simple; But timber compressive strength is lower; Can produce moderate finite deformation after stressed, and timber wedge takes off by the workman easily, cause potential safety hazard to construction.
Pre-buried dowel method: dowel palintrope welding; Method is simple, and certain fastening force is arranged, and seeks conveniently but in construction, often exist for; Directly the reinforced steel bar ring bending is compressed the phenomenon of shaped steel; This method can make dowel and shaped steel combine closely outwardly, but after reinforced steel bar ring is stressed, very easily is straightened, and brings unsafe factor for scaffold safety.
The embedded iron parts method: embedded iron parts and shaped steel welding are fixing, safe and reliable, but embedded iron parts can not reclaim; Meeting generation contraction in length or cross section were damaged after the steel member cut off during dismounting; Material cost is higher, and the field Welding engineering quantity is bigger, and weldquality is difficult to control.
The utility model content
The problem that the utility model will solve is to above deficiency, provides a kind of simple to operate, safe fixedly shaped steel builder's jack to use connector.
For addressing the above problem; The utility model has been taked following technical scheme: a kind of fixedly shaped steel builder's jack is used connector; It is characterized in that: comprise two hardwares, an end of hardware has kink, and the other end of hardware has the threaded portion; Be provided with fixed head between the threaded portion of two hardwares, fixed head and hardware are for removably connecting.
Further improvement as technique scheme:
The threaded portion is provided with nut.
The end of kink is provided with invayination.
The utility model adopts above technical scheme; Compared with prior art, have the following advantages: each pre-buried hardware of the both sides of shaped steel during use, the kink of hardware is pre-buried to the reinforcing bar of floor; Shaped steel top adopts fixed head boring to fix with nut with the threaded portion; Adopt the method, simple to operate, safe and reliable.Stopped pre-buried U type ring and contacted imprecision, the potential safety hazard that adopts timber wedge to cause with shaped steel.
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Description of drawings
Accompanying drawing 1 is the structural representation of connector among the utility model embodiment;
Among the figure,
The l-hardware, 2-reinforcing bar, 3-fixed head, 4-shaped steel, 5-nut, 6-floor, 7-kink, 8-threaded portion, 9-invayination.
The specific embodiment
Embodiment, as shown in the figure, fixedly the shaped steel builder's jack is used connector; Comprise two hardwares 1, hardware 1 usefulness reinforcing bar is processed, and an end of hardware 1 has kink 7; The end of kink 7 is provided with invayination 9, and the other end of hardware 1 has between the threaded portion 8 of 8, two hardwares 1 in threaded portion and is provided with fixed head 3; Fixed head 3 removably connects with hardware 1, is fixed together through nut 5.
During use, each pre-buried hardware 1 of the both sides of shaped steel 4, the kink 7 and the invayination 9 of hardware 1 is pre-buried to the reinforcing bar 2 of floor 6, and shaped steel 4 tops adopt fixed head 3 borings fixing with threaded portion 8 usefulness nuts 5; Adopt the method, simple to operate, safe and reliable.Stopped pre-buried U type ring and contacted imprecision, the potential safety hazard that adopts timber wedge to cause with shaped steel.
The kink of hardware 17 is pre-buried to the reinforcing bar 2 of floor 6 time; If can not guarantee the thickness of reinforced concrete protective layer; Also can kink 7 be fixed on above lower floor's reinforcing bar 2 of floor 6; But must be firm with the floor bar colligation, can from concrete floor 6, not extract to guarantee kink 7.
