Abstract
The utility model discloses a kind of corner back cord, including orthogonal vertical edge and horizontal edge, vertical edge and horizontal edge are two pipes being parallel to each other；The back cord also includes flat board, and flat board is located at the junction of vertical edge and horizontal edge, and vertical edge is welded on the upper surface of flat board, and horizontal edge is welded on the lower surface of flat board.The utility model devises a kind of structure of brand-new corner back cord, and for the fixed transfer in corner, the structure has good intensity, is unlikely to deform, and right angle can be kept well.
Description
Technical field
The utility model is related to a kind of corner back cord, belongs to building template field.
Background technology
Back cord is the back for concrete blinding, the structure for adjusting fixing concrete template.Corner back cord is to use
On the corner wall, can be made of steel pipe.But existing corner back cord is substantially on-site consolidation, angle is difficult quick adjustment
For right angle；Meanwhile, it is difficult to be fixedly connected well between steel pipe, its angle is also easier to change in use, it is difficult to
Keep at a right angle.
Utility model content
The technical problem that the utility model is solved is to design the back of the body that a kind of corner for fixing concrete template is used
It is stupefied, it is rectangular for convenient adjustment and holding corner.
The technical solution of the utility model is to provide a kind of corner back cord, including orthogonal vertical edge and horizontal edge, vertical edge
It is two pipes being parallel to each other with horizontal edge；The back cord also includes flat board, and flat board is located at the junction of vertical edge and horizontal edge, vertical edge
The upper surface of flat board is welded on, horizontal edge is welded on the lower surface of flat board.
Preferred scheme, the flat board upper surface is additionally provided with the contiguous block of right angled triangle, two right-angle sides point of contiguous block
Not with vertical edge and plate welding.The connecting rod of a hypotenuse of only right angled triangle can certainly be simplified to, with vertical edge, horizontal stroke
The stable right angled triangle of side composition, the weld seam so welded only has two tie points, rather than two right-angle sides.
Preferred scheme, the both sides of the flat board are respectively equipped with side plate, and side plate is located at the lower section of flat board, and horizontal edge is also welded on side
The inner surface of plate.
Preferred scheme, the length of the flat board is 4-20 centimetres.
Preferred scheme, the vertical edge is constituted with horizontal edge by the pipe more than two sections being mutually inserted.
The both sides of corner back cord of the present utility model use dual tube designs, are connected using the corner back cord of two-tube composition at it
The end face connect is the welding of plane and curved surface, the problem of there is welding inconvenience and not prison welding, so the present invention is in its junction
With the addition of one piece be used for weld flat board.For vertical edge, the contact surface of flat board and vertical edge is vertical edge end face, and weld seam is same plane
Two circles, easily welding, while be easy to welding when keep vertical edge it is vertical with flat board；For horizontal edge, flat board and horizontal stroke
While being parallel to each other, weld seam is conplane straight line, and welding is easier to, while being also convenient for keeping flat board parallel with horizontal edge.
Further to strengthen the structure of the corner back cord, the corner back cord is set to keep right angle, can turning in corner back cord
Design is strengthened at angle connecting rod or contiguous block, contiguous block are located at corner, and simplest structure is the company of right angled triangle
Block is connect, is respectively welded on horizontal edge and vertical edge.
For the two-tube of further fixed horizontal edge, it can also be welded in two-tube side, better simply effective structure
Two side plates are set below flat board, its size Control is located just at two-tube tangential direction in side plate, you can be welded and fixed.
Now, two side plates are preferably integrated structure with flat board, to ensure that it can provide enough intensity.
The beneficial effects of the utility model are to devise a kind of structure of brand-new corner back cord, the fixation for corner
Switching, the structure has good intensity, is unlikely to deform, and right angle can be kept well.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
Embodiment 1：The present embodiment provides a kind of exterior angle back cord, that is, the flat board welded and other structures strengthened are located at back cord
Outside, its three-view diagram is as Figure 1-3.The vertical edge 1 and horizontal edge 2 of back cord design for spigot-and-socket, and vertical edge 1 and horizontal edge 2 are two
The steel pipe being parallel to each other；Multiple welding bars are provided between two steel pipes, is respectively welded and is fixed with two steel-pipe weldings.Horizontal edge 2
It is about the rectangular flat boards 3 of 10cm that one end, which sets a length, and width is equal with the width of horizontal edge 2, in width provided with two pieces of sides
Plate 5, its structure such as horizontal edge 2 are enclosed in the structure that flat board 3 and two blocks of side plates 5 are surrounded（As shown in Figure 4）, weld on the contact surface solid
It is fixed（Certainly it is further reinforcement, one block of plate can also be set again in bottom surface, a cuboid without bottom surface and top surface is surrounded.）Vertical edge
1 is weldingly fixed on the upper surface of flat board 3.A contiguous block 4 is also welded with the upper surface of flat board 3, contiguous block 4 is right angle trigonometry
Shape a, right-angle side is welded on the upper surface of flat board 3, and another right-angle side is welded on vertical edge 1.
Embodiment 2：The present embodiment provides a kind of interior angle back cord, and its structure is similar with embodiment, and its three-view diagram is as schemed
5-7, the difference of itself and embodiment 1 is：Structure for the flat board of welding and other reinforcements is located inside back cord.
In exterior angle back cord in the utility model, vertical edge and horizontal edge can be with equivalent substitutions, wherein " perpendicular " and " horizontal stroke " is only
It is for convenience, to be not offered as its actual use constantly vertically and horizontally.Flat board can be parallel with horizontal edge, is hung down with vertical edge
Directly；Can certainly in turn, flat board can be vertical with vertical edge, parallel with horizontal edge.
