Abstract
The utility model relates to an energy-saving window screen sealing section, wherein, a cold-rolled strip is cold rolled into the section with a hollow Z-shaped body cross section. During the rolling process, the inner side surfaces of two corners of the body are respectively recessed with a dovetail groove of different opening directions. A frame assembled by using the section can simultaneously meet the requirements of sealing and accessorial screen for building a metal window; the procedure of pressing is simplified by adopting an embedded type pressing method; the window screen is arranged in indoor direction so that the window screen can be cleaned and replaced at any time and the air tightness of the window can be improved effectively, so the utility model has the function of energy saving.
Description
The utility model relates to a kind of cold rolling special-shaped hollow section, refers to a kind of energy-conservation airtight window screen section especially.
The utility model belongs to the structural metal door-window section bar and makes the field.
For a long time, the employed window screen section of China's structural metal door and window is the small-sized channel-section steel of a kind of hot rolling, with its frame that is made into, can make the airtight frame or the screen window frame of door and window.When making airtight frame, be, can install and use, but when making the screen window frame, just must window screening be pressed in the groove, use many screws that band steel and channel-section steel is fastening again, can reach instructions for use with the band steel that adapts with in the airtight adhesive tape embedded groove.This screen window frame is when making and press yarn, and operation is more, cumbersome, time-consumingly takes a lot of work, the cost height; In use, if clean, change window screening, need the screen window frame is unloaded from door and window, very inconvenience.It is can not satisfy the requirement of door and window to airtight and attached yarn with the frame of this section bar making simultaneously during use to ordering shortcoming.
The purpose of this utility model provides and a kind ofly can satisfy door and window simultaneously to airtight and attached yarn requirement, can adopt advanced embedded pressure yarn method, can improve the door and window tightness, and have the section bar of energy-conserving action, to overcome the shortcoming of prior art.
The utility model is taked following technical scheme:
Be the garden type with the cold rolling one-tenth cross section of cold-rolled strip earlier, through the high-frequency welding interface, being closed shaped steel, is the section bar of empty stomach " Z " shape by cold rolling one-tenth main body 1 cross section, at the different dovetail groove 2 of each recessed opening direction of medial surface of 1 liang of corner of operation of rolling medium section main body again.
The utility model cost is low, and manufacturing process is simple, with its frame of making, is used airtight adhesive tape and presses the yarn adhesive tape in two dovetail grooves 2, can satisfy the requirement of door and window to airtight and attached yarn simultaneously; Adopt advanced embedded pressure yarn method, simplified pressure yarn operation; Can improve the tightness of door and window, have energy-conserving action; Highly versatile can be realized installing under the situation that need not to change existing door and window hardware part; Window screening is arranged on indoor direction, and need not to unload frame can clean, change window screening, extremely easy to use, compared with prior art has very strong practicality.
The utility model embodiment accompanying drawings.
Accompanying drawing is the utility model embodiment schematic diagram.
Embodiment:
As shown in the figure, be energy-conservation airtight window screen section.Adopting material is the cold-rolled strip or the cold rolling roll bending of GB700 regulation, thick 1.2mm, main body 1 cross section is empty stomach " Z " shape, and the horizontal length of side of its two corners lateral surface is 13.5mm, vertical length of side 10mm, H=3.8mm, α=51.7 °, the trapezoidal upper base 5mm of dovetail groove cross section, 7mm goes to the bottom, high 4mm, dovetail groove center to vertical edges is 8mm.
The buckling degree of main body 1 is not more than 1mm for every meter among the embodiment, and torsion resistance is not more than 0.8mm for every meter, dovetail groove 2 upper base deviation ± 0.2mm, H deviation ± 0.2mm.
The utility model is to satisfy the feasibility section bar of structural metal door and window to airtight and attached yarn requirement simultaneously, uses its section bar can improve the tightness of door and window, has energy-conserving action, for improving the function of use of door and window, has filled up a blank.
Claims (1)
- A kind of energy-conservation airtight window screen section, it is characterized in that the section bar main body (1) of " Z " shape constitutes with two different dovetail grooves (2) of opening cross section by being on an empty stomach, section bar main body (1) angle of slope (α) that constitutes of the corner inclined plane of " Z " shape and lateral surface on an empty stomach is an acute angle, and two dovetail grooves (2) lay respectively at section bar main body (1) on an empty stomach on the medial surface of " Z " shape two corners.
