Description
Technical Field
The utility model relates to a construction engineering field, especially steel structural connection spare for building.
Background
The scaffold refers to various supports erected on a construction site for workers to operate and solve vertical and horizontal transportation. The method is used in places where external walls, interior decoration or high floor height cannot be directly constructed, and is mainly used for up-and-down dry work of constructors, maintenance of peripheral safety nets, high-altitude installation of components and the like. The existing scaffold is generally formed by mutually staggering and building steel pipes, and connecting pieces are generally required to be adopted for fastening at the joints.
At a part of the connection part, the situation that a plurality of steel pipes in the transverse direction, the longitudinal direction, the oblique direction and the like are connected at the same time often exists; the existing connecting piece cannot connect a plurality of steel pipes and is often lapped at a non-vertical node, so that the transverse steel pipes are bent; meanwhile, for some oblique steel pipes, the oblique angles of the steel pipes are different, so that the connecting piece is required to be connected with the steel pipes at various angles, and adjustment and fastening are facilitated.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned condition, for solving the problem that exists among the prior art, the utility model aims at providing a steel structure connecting piece for building, can effectively solve scaffold frame connection angle limited, mediate inconvenient problem.
The technical proposal for solving the problem is that the steel tube comprises a main steel tube which is vertically arranged; an upper chuck and a lower chuck are movably sleeved on the main steel pipe, annular grooves are formed in the two chucks, and the annular grooves in the upper chuck and the annular groove in the lower chuck are opposite; a plurality of vertically arranged arc-shaped plates are arranged in the upper annular groove and the lower annular groove, and a hinge is fixedly arranged on the outer side surface of each arc-shaped plate; the upper side of the upper chuck and the lower volume of the lower chuck are provided with a hoop which tightly holds the steel pipe body.
The utility model discloses convenient operation, the structure is ingenious, low cost, and it is convenient to make, and is safe effective, has improved portability and the security that the scaffold was built greatly.

Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1 to 3, the present invention includes a vertically disposed main steel pipe 1; an upper chuck 2 and a lower chuck 3 are movably sleeved on the main steel pipe 1, annular grooves 4 are formed in the two chucks, and the annular grooves 4 on the upper chuck and the lower chuck are opposite; a plurality of arc-shaped plates 5 which are vertically arranged are arranged in the upper annular groove 4 and the lower annular groove 4, and a hinge 6 is fixedly arranged on the outer side surface of each arc-shaped plate 5; the upper side of the upper chuck 2 and the lower volume of the lower chuck 3 are both provided with a hoop 7 which tightly holds the steel pipe body.
In order to connect a plurality of bypass steel pipes, a plurality of groups of chucks can be arranged between the upper hoop 7 and the lower hoop 7.
In order to better realize the holding tightly of staple bolt 7 to the steel pipe, the medial surface of staple bolt 7 be equipped with tooth, there is rubber pad 8 between the medial surface of staple bolt 7 and the steel pipe body.
In order to realize the connection between the end part of the bypass steel pipe and the arc-shaped plate 5, the end part of each bypass steel pipe is provided with a hinge 6; the articulation of the by-pass steel pipe ends and the hinges 6 outside the arc 5 can be achieved by means of removable bolts.
When the utility model is used, firstly, the height of the bypass steel pipe to be installed on the main steel pipe 1 is calculated reasonably, and the height is marked by chalk and the like; then, sleeving an upper chuck 2 and a lower chuck 3 on the main steel pipe 1, and reasonably adding an upper chuck group and a lower chuck group according to the position and the number of the bypass steel pipes required to be connected by the node; after the chuck is installed, the hoop 7 positioned below is fixed at the moment, so that the chuck is positioned at the previous mark.
Then, according to the number of the bypass branch pipes, arc plates 5 with corresponding number are placed in the annular grooves 4 of the upper chuck and the lower chuck; the upper chuck 2 is not pressed at this time, so that the angle between the respective arc plates 5 can be easily adjusted.
Then, hinges 6 at the end parts of the bypass steel pipes are hinged with hinges 6 on the arc-shaped plates 5 through bolts, and when all the bypass steel pipes are hinged, the hinges are not hinged; the angle of the whole scaffold is adjusted, and the hoop 7 positioned above is tightly pressed on the upper chuck 2 and then fixed tightly; thereby completing the connection of the whole scaffold.
When the device needs to be disassembled, the by-pass steel pipe can be removed directly by removing the bolt pin between the by-pass steel pipe and the arc-shaped plate 5; meanwhile, if the node position of the next construction is not changed, the hoop 7 does not need to be loosened; when the construction is carried out next time, the height of the node or the angle of the bypass steel pipe is inconsistent, the adjustment can be carried out by adjusting the hoop 7.
The device has simple structure and convenient operation, and has strong adjustability when in use; the height of the connecting piece, namely the height of the node can be easily adjusted by adjusting the vertical height of the hoop 7; therefore, the height between each layer can be reasonably adjusted according to the height of the needed scaffold.
The upper chuck and the lower chuck are arranged in the device, so that the arc-shaped plate 5 can freely rotate in the annular grooves of the upper chuck and the lower chuck, and the connection of bypass steel pipes at various angles of a horizontal plane can be met; then, the adjustment of the inclination angle in the vertical plane of the bypass steel pipe is realized through the hinge between the bypass branch pipe and the arc-shaped plate 5, so that the building of scaffolds in various forms is met.
When the device is used, the upper and lower chucks 3 can be further arranged in a plurality of groups, so that the installation of bypass steel pipes between different angles in the same vertical plane can be realized at the node.
The utility model discloses convenient operation, the structure is ingenious, low cost, and it is convenient to make, and is safe effective, has improved portability and the security that the scaffold was built greatly.
