The caash bar of architecture advances

The improvement of the relevant a kind of door frame structure of the utility model system, particularly a kind ofly simultaneously two side door mouldings and moulding are to the doorstep made one at the doorframe rolling and forming, and therebetween offer the bending slotted eye of V font and lockhole etc., so that after rolling finishes, need only be plastic doorframe through bending.

The fabrication schedule of doorframe was in the past: after sheet metal being inserted the length of doorframe forming machine roll forming one side door bar, promptly cut off work, and to make the opposite side caash bar again with method and to the doorstep behind the moulding, carrying out lockhole, door hinge hole etc. with manual type offers, after treating that these steps are finished, with two side door mouldings of aforementioned intercept and moulding seam or insert contract between caash bar with the right angle junction piece to the doorstep, make up in the mode of being spirally connected, then this doorframe can use again again.

From aforementioned manufacturing process, can understand, because after three caash bars are finished, the work that must carry out seam or be spirally connected, so the length of aforementioned moulding making to the doorstep must be greater than the real width of door, just foot is in the work of carrying out seam or being spirally connected, therefore, to cause and whenever manufacture a doorframe and promptly waste a little material, and as if after this method for making is produced in a large number, the waste that causes is then considerable, so must pay attention to.

Again; offering job families such as lockhole, door hinge hole in the tradition doorframe manufacture process carries out after the doorframe rolling is finished; this mode when construction regular meeting take place that aforementioned apertures is wide open establishes difficult situation; after meaning promptly is shaped by doorframe; its section configuration system is crooked uneven, so will cause very big inconvenience for the work of offering of each hole.

For this reason, the purpose of this utility model provides a kind of caash bar that is easy to constitute doorframe and saves the sheet metal materials.

The utility model is achieved in that caash bar is to be made by sheet metal, it comprises a side door moulding that connects successively, call moulding and opposite side caash bar, have between them to be bent into the bending hole of one doorframe, on the appropriate location of side door moulding, be provided with threshold hole, lockhole, door hinge hole; Be provided with fixing hole on the moulding to the doorstep.For this reason, aforementioned metal sheet material offers lockhole, door hinge hole, fixing hole, threshold hole prior to the appropriate location before the rolling construction, and after rolling is finished a side door moulding length, offer the bending slotted eye that is shaped in order to bending, and go out moulding length to the doorstep in the follow-up rolling of this slotted eye, offer another aforementioned bending slotted eye again, rolling goes out opposite side caash bar length more at last, forms a kind of at two side door mouldings and only offer to the doorstep the caash bar of the slotted eye that is shaped in order to bending between moulding.

Advantage of the present utility model is as follows:

1. because behind the two side door mouldings and the moulding roll forming of calling, do not block work, only offer the bending slotted eye of a V font, therefore, aforementioned each caash bar is by the position of this slotted eye, promptly can be bent into shape, and must not adopt the mode of aforementioned seam or joint, will be more easy, convenient so construction is gone up, simultaneously because the utility model adopts the bending forming mode, so to the doorstep the making of moulding need not the length reserving seam or be spirally connected, therefore saves sheet metal, cost greatly reduces; 2. owing to before sheet metal carries out rolling, promptly earlier calculate good each hole and offer the position and offer it, therefore, owing to be a flat board before the sheet metal rolling, so unlikelyly as having caash bar, exist various holes to offer difficult problem.

About the technical application and the detailed structure of the utility model, existing conjunction with figs. is described as follows:

Fig. 1 is the front elevational schematic of the not rolling sheet metal of the utility model.

Fig. 2 is the three-dimensional appearance schematic diagram of the utility model.

Fig. 3 is the local structure schematic diagram of the utility model.

Fig. 4 is the use illustration intention of the utility model.

Fig. 5 is another embodiment schematic diagram of the utility model.

Provide better embodiment of the utility model according to Fig. 1～Fig. 4, and, further provide ins and outs of the present utility model in conjunction with description to this embodiment.

At first see also Fig. 1, this figure represents that the sheet metal 2 of the utility model is not when carrying out rolling work as yet, promptly earlier with lockhole 10, yielding rubber hole 11,11 ', the door hinge hole 12,12 ', fixing

hole
