Description
Technical field
The utility model relates to a kind of construction implement, particularly relates to a kind of top keel connecting structure of scaffold support system.
Background technology
Usually use scaffold as the support system of template in current structure of reinforced concrete process.As shown in Figure 1, in prior art, the top keel usual 50 of scaffold are generally used for the below supporting masterplate.Top keel 50 can bear larger load in concreting process.In order to strengthen the supporting capacity of top keel 50, usually the mode that two scaffolding steel pipes weld side by side is welded together in prior art.One in two steel pipes is connected to scaffold upright rod 52 by fastener 51.
There are the following problems for the top keel of scaffold of the prior art: top keel 50 are connected to scaffold upright rod 52 by fastener 51.In fastener connected mode, support system keeps the stable of support system by the frictional force between fastener and steel pipe.When the load that top keel 50 bear is excessive, the slip between top keel 50 and fastener 51 can be caused, thus cause the distortion of support system even to cave in.In addition, the top keel 50 adopting two steel pipe weldings to be connected into and the junction of scaffold upright rod 52 are still single steel pipe, and this makes top keel 50 still there is weak link.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of top keel connecting structure of scaffold support system, and the top keel connecting structure of scaffold support system of the present utility model can solve the top main joist Problems existing of scaffold support system in prior art.
The technical solution of the utility model provides a kind of top keel connecting structure of scaffold support system, and it comprises:
Square steel keel, the steel pipe that described square steel keel are rectangle by cross section is made, and the two ends of described square steel keel are respectively fixedly connected with a spline adapter; Described spline adapter vertically offers low wide and up narrow dovetail groove;
Scaffold upright rod, the top of described scaffold upright rod is fixedly connected with the trapezoidal pin coordinated with described spline adapter, width outside described trapezoidal pin is greater than its width near described scaffold upright rod side, and the width bottom described trapezoidal pin is greater than the width at its top; The described trapezoidal pin of described scaffold upright rod end is inserted in the described dovetail groove of described spline adapter from below.
The further improvement of the top keel connecting structure of scaffold support system of the present utility model is: described spline adapter is fixedly connected on the end of described square steel keel by the mode of welding.
The further improvement of the top keel connecting structure of scaffold support system of the present utility model is: the top of described scaffold upright rod is connected with four trapezoidal pins, and four described trapezoidal pins are equally spaced around the side being distributed in described scaffold upright rod end.
The Advantageous Effects of the top keel connecting structure of scaffold support system of the present utility model is: square steel keel adopt square steel pipe to make, the top keel be welded into side by side with two steel pipes in prior art are compared, and square steel keel have better stress performance and larger intensity.Scaffold upright rod is connected with the mode of top keel by keyway socket joint, and this connected mode can be installed fast.

Detailed description of the invention
Below by way of specific instantiation, embodiment of the present utility model is described, those skilled in the art the content disclosed by this manual can understand other advantages of the present utility model and effect easily.The utility model can also be implemented or be applied by detailed description of the invention different in addition, and the every details in this manual also can based on different viewpoints and application, carries out various modification or change not deviating under spirit of the present utility model.
Be introduced below in conjunction with the top keel connecting structure of accompanying drawing to scaffold support system of the present utility model:
As shown in Figures 2 and 3, the top keel connecting structure of scaffold support system of the present utility model comprises: square steel keel 10 and scaffold upright rod 11, and the two ends of the square steel keel 10 arranged in the horizontal direction are connected to the top of two scaffold upright rods 11.
As shown in Figures 2 and 3, the steel pipe that square steel keel 10 are rectangle by cross section is made.The two ends of square steel keel 10 are respectively fixedly connected with a spline adapter 12.Spline adapter 12 vertically offers low wide and up narrow dovetail groove 13.In the present embodiment, spline adapter 12 is made up of cast steel, and spline adapter 12 is fixedly connected on the end of square steel keel 10 by the mode of welding.The dovetail groove 13 of the spline adapter 12 of square steel keel 10 both sides is parallel to each other.
The top of scaffold upright rod 11 is fixedly connected with the trapezoidal pin 14 coordinated with spline adapter 12.Trapezoidal pin 14 is vertically connected to the side on scaffold upright rod 11 top.Width outside trapezoidal pin 14 is greater than its width near scaffold upright rod 11 side, and this makes the cross section of trapezoidal pin 14 be trapezoidal.In order to coordinate with the up-narrow and down-wide dovetail groove 13 of spline adapter 12, the width bottom trapezoidal pin 14 is greater than the width at its top.In use, the trapezoidal pin 14 of scaffold upright rod 11 end is inserted in the dovetail groove 13 of spline adapter 12 from below.Because the dovetail groove 13 of spline adapter 12 and trapezoidal pin 14 are up-narrow and down-wide shape, therefore when square steel keel 10 bearing load, trapezoidal pin 14 can support spline adapter 12 and square steel keel 10.
In the present embodiment, the top of scaffold upright rod 11 is connected with four trapezoidal pins, 14, four trapezoidal pins 14 equally spaced around the side being distributed in scaffold upright rod 11 end.
The Advantageous Effects of the top keel connecting structure of scaffold support system of the present utility model is: square steel keel 10 adopt square steel pipe to make, the top keel be welded into side by side with two steel pipes in prior art are compared, and square steel keel 10 have better stress performance and larger intensity.Scaffold upright rod 11 is connected with the mode of square steel keel 10 by keyway socket joint, and this connected mode can be installed fast.Adopt the connected mode of keyway socket joint can also avoid in traditional fastener connected mode, between fastener and steel pipe, producing the problem loosened because load is excessive.
The above is only preferred embodiment of the present utility model, not any pro forma restriction is done to the utility model, although the utility model discloses as above with preferred embodiment, but and be not used to limit the utility model, any those skilled in the art, not departing from the scope of technical solutions of the utility model, make a little change when the technology contents of above-mentioned announcement can be utilized or be modified to the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
