The structure of the left-end section is improved, and the clamping groove is added, so that the steel part can be integrally attached to the frame of the section, and the structural strength of the whole section is enhanced; on the other hand, the fireproof expansion strip is added in the profile, so that the fireproof effect of the profile is further enhanced.
Description
Technical Field
The utility model relates to a door and window section bar technical field, especially a window frame section bar.
Background
As shown in fig. 1, the window frame profile is used for installing a window sash, and is an essential profile in a door and window profile. The existing window frame section is usually formed by splicing two section buckles; then arranging a steel piece on the spliced integral section bar, wherein the steel piece is required to be arranged on the bulge at the upper right corner of the left section bar due to the position of the bulge at the upper right corner of the left section bar; in such a structural mode, a cavity is formed between the steel part and the integral profile, the steel part is easy to deform, and the mechanical strength of the whole window frame is further low; simultaneously when receiving the exogenic action, the steel part can be raised certain pressure that produces to the upper right corner, leads to whole window frame to produce and takes place the deformation easily, causes the window frame to damage.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome that current window frame intensity is lower, produces the problem of deformation easily, provides a window frame section bar.
A window frame section comprises a first section and a second section, wherein the right end of the first section is connected with the left end of the second section through a heat insulation strip buckle; the bulge at the upper right corner of the first section bar and the upper frame of the first section bar form a clamping groove; an L-shaped steel piece is further arranged between the first profile and the second profile, and the left end of the bottom edge of the L-shaped steel piece is buckled inside the clamping groove.
Furthermore, the bottom of the bottom edge of the L-shaped steel piece is also provided with a first fireproof expansion strip.
Furthermore, the L-shaped steel piece and the left end of the first fireproof expansion strip are fastened on the first section bar through screws.
Further, a second fireproof expansion strip is arranged between the first profile and the second profile; the second fireproof expansion strip is positioned between the two heat insulation strips.
Further, the cavity of the second section bar is internally provided with a third fire-proof expansion strip and a structure inserting strip, and the structure inserting strip is positioned on the left side of the third fire-proof expansion strip.
The utility model has the advantages that: the structure of the left-end section is improved, and the clamping groove is added, so that the steel part can be integrally attached to the frame of the section, and the structural strength of the whole section is enhanced; on the other hand, through adding fire prevention inflation strip and structure cutting in the section bar inside, further strengthened the fire prevention effect of section bar.

Detailed Description
The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic concept of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the form, amount and ratio of the components in actual implementation may be changed at will, and the layout of the components may be more complicated.
Example (b):
as shown in fig. 2 to 3, a window frame profile comprises a first profile 1 and a second profile 2, wherein the right end of the first profile 1 is connected with the left end of the second profile 2 through a heat insulation strip 6 in a buckling manner;
the bulge at the upper right corner of the first section bar 1 and the upper frame of the first section bar 1 form a clamping groove 11; an L-shaped steel part 3 is further arranged between the first profile 1 and the second profile 2, and the left end of the bottom edge of the L-shaped steel part 3 is buckled inside the clamping groove 11. The L-shaped steel piece 3 is integrally attached to the upper frame of the second section bar 2 of the first section bar 1; the left-end section structure is improved, and the clamping groove 11 is added, so that a steel part can be integrally attached to a section frame, and the structural strength of the whole section is enhanced; the condition that the window frame is damaged due to the generation of the section bar when external force is applied is prevented.
And a first fireproof expansion strip 4 is further arranged at the bottom of the bottom edge of the L-shaped steel piece 3. The L-shaped steel member 3 and the first fireproof expansion strip 4 are fixed on the section bar through screws. The left ends of the L-shaped steel piece 3 and the first fireproof expansion strip 4 are fastened on the first section bar 1 through screws. A second fireproof expansion strip 5 is also arranged between the first profile 1 and the second profile 2; the second fire-resistant expansion strip 5 is located between two heat insulation strips 6.
The inside third fire prevention inflation strip 7 and the structure cutting 8 that still is provided with of cavity of second section bar 2, structure cutting 8 is located the left side of third fire prevention inflation strip 7. The structure cutting 8 is used for pushing down third fire prevention inflation strip 7, and fire burns from the outdoor, burns the structure cutting 8 earlier, and when structure cutting 8 kept off, just burnt third fire prevention inflation strip 7, third fire prevention inflation strip 7 expanded to the both sides of structure cutting 8, and the fire prevention once more reaches the purpose that increases the fire prevention effect of section bar.
The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
