The scaffold support bar
Technical field
The utility model relates to building auxiliary appliance technical field, is specifically related to a kind of scaffold support bar.
Background technology
The scaffold support bar generally is made up of the raising-plate that a screw rod and is connected screw rod one end, it is aid commonly used in the construction work, it plays the effect of supporting unsettled object in the building place, and the compressive resistance of scaffold support bar is directly connected to building safety.Existing scaffold support bar all has compressive resistance preferably in order to make raising-plate and screw rod, adopt solid iron to make screw rod, and adopt solid iron plate to make raising-plate, though this scaffold support bar can reach the requirement of strength of construction work, but expend iron material, manufacturing cost height, and solid iron plate and solid iron are all comparatively heavy, are not easy to carrying, are unfavorable for the flexible use of staff to the scaffold gripper shoe.
Summary of the invention
In view of this, the technical problems to be solved in the utility model provides a kind of light, low cost of manufacture, scaffold support bar that intensity is high.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of scaffold support bar comprises screw rod and the raising-plate that is connected screw rod one end, and described screw rod is a cored screw, and described raising-plate is the hollow steel plate of punch forming.
Technique scheme adopts cored screw and hollow steel plate to be assembled into the scaffold gripper shoe, its manufacturing cost of reduction of very big degree, and the overall weight of scaffold gripper shoe is significantly reduced, make that the scaffold support bar is more apparent lightly easily to be moved, thereby be beneficial to the staff its flexible use.
As scheme more preferably, above-mentioned hollow steel plate center is provided with screwed hole, cored screw and hollow steel plate are spirally connected, this helps and as required raising-plate and screw rod is loaded and unloaded, further be convenient to the staff to the moving of scaffold support bar, and raising-plate and screw rod separately can be used where necessary.Certainly, if actual needs can also directly be welded to cored screw on the hollow steel plate.
In order to strengthen the withstand voltage degree of scaffold support bar, the hollow surface of steel plate of above-mentioned punch forming is provided with many reinforcing ribs that play booster action by stretching, simultaneously cored screw is carried out cure process and makes screw rod possess high pressure withstanding degree.
Particularly, above-mentioned reinforcing rib is six, and wherein four become X-shaped to arrange around cored screw, and two other laterally is located at respectively in any two relative angles of X-shaped.
Compared with prior art, the utlity model has following advantage:
1, the utility model adopts cored screw and hollow steel plate to be assembled into the scaffold gripper shoe, the saving manufactured materials of very big degree, reduce manufacturing cost, and the overall weight of scaffold gripper shoe is significantly reduced, make that the scaffold support bar is more apparent lightly easily to be moved, thereby be beneficial to the staff its flexible use.
2, the hollow surface of steel plate of the punch forming in the utility model is provided with many reinforcing ribs that play booster action by stretching, effectively strengthens the withstand voltage degree of scaffold support bar.

The specific embodiment
For the ease of it will be appreciated by those skilled in the art that the utility model is explained in further detail below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1, 2, a kind of scaffold support bar comprises screw rod 1 and the raising-plate 2 that is connected screw rod one end, and screw rod 1 is a cored screw, and described raising-plate 2 is the hollow steel plate of punch forming.In the present embodiment, it is the hollow steel plate of 2.0MM that raising-plate adopts thickness, the raising-plate thickness of tradition scaffold gripper shoe is generally 5MM, therefore raising-plate of the present utility model is saved a half-finished material than traditional scaffold gripper shoe, and screw rod of the present utility model is a cored screw, and this has just further saved raw material.Hollow steel plate center is provided with screwed hole, cored screw is inserted in the screwed hole and is spirally connected with hollow steel plate, hollow surface of steel plate also is provided with six reinforcing ribs 21 that play booster action by stretching, and six there are four to become X-shaped to arrange in the reinforcing rib around cored screw, two other laterally is located at respectively in any two relative angles of X-shaped, and above-mentioned cored screw is through cure process.
Above-mentioned scaffold support bar is assembled into the scaffold gripper shoe because of adopting cored screw and hollow steel plate, greatly the saving manufactured materials of degree, reduce its manufacturing cost, and the overall weight of scaffold gripper shoe is significantly reduced, make that the scaffold support bar is more apparent lightly easily to be moved, thereby be beneficial to the staff its flexible use.And cored screw and hollow steel plate are bolted with and are beneficial to and as required raising-plate and screw rod are loaded and unloaded, and further are convenient to the staff to the moving of scaffold support bar, and raising-plate and screw rod separately can be used where necessary.In addition, be provided with reinforcing rib, effectively strengthened the intensity of scaffold support bar, effectively promoted its voltage endurance capability at hollow surface of steel plate.
The foregoing description is a preferred implementation of the present utility model, and in addition, the utility model can also have other implementations.That is to say that under the prerequisite that does not break away from the utility model design, any conspicuous replacement also should fall within the protection domain of the present utility model.
