Description

Profiles for new doors and windows

technical field

The utility model relates to the field of door and window profiles, in particular to a novel door and window profile with simple structure and reasonable design.

Background technique

At present, door and window building materials have gone through stages such as wooden doors and windows, iron doors and windows, aluminum alloy doors and windows, plastic doors and windows, etc. The functions of doors and windows are getting stronger and stronger, and the decorative and practical effects are constantly increasing. In recent years, many aluminum-plastic composite profile products have appeared, which have the advantages of both aluminum and plastic materials and are relatively beautiful in appearance, but there are different degrees of deficiencies in structure. Broken bridge aluminum profile: poor heat insulation effect, high cost; armored aluminum composite profile: due to the different thermal expansion coefficients of aluminum and plastic, the adhesion is poor, and the window must be connected with screws, the operation is complicated and the workmanship is poor. In addition, rainwater easily enters the interlayer. It is easy to freeze in winter and easy to leak in summer, which affects the service life; single-sided and double-sided aluminum-plastic composite profiles: because the aluminum material is only compounded on the plastic surface, the profile strength is poor, the wind pressure resistance index is low, and the thermal insulation effect is not ideal.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a new door and window profile with simple structure and reasonable design, which can effectively reduce the energy transmission indoors and outdoors, have good heat preservation effect, and effectively enhance the bending resistance of the profile.

According to the design scheme provided by the utility model, a new profile for doors and windows includes a profile body. The profile body is provided with a thermal insulation cavity and a steel lining cavity. Two installation mechanisms are provided at the section of the profile body. A side bar, a second side bar and a beam connecting the first side bar and the second side bar, the first side bar and the second side bar are both provided with installation flanges.

As mentioned above, the installation flange is an installation protrusion, or an "L"-shaped installation edge perpendicular to the first edge and the second edge.

As mentioned above, the heat preservation chamber includes a first heat preservation chamber and a second heat preservation chamber, and connecting internal ribs are arranged between the first heat preservation chamber and the second heat preservation chamber.

As mentioned above, the profile body is made of plastic material.

The beneficial effects of the utility model:

The utility model has the advantages of simple structure, novel and reasonable design, adopts plastic profiles, fixes and installs through two side strips and the installation folds on the side strips, the installation method is flexible and reliable, and the side strips are connected by cross beams, so the fixing is firm. It is not easy to loosen and deform. The heat preservation chamber includes the first heat preservation chamber and the second heat preservation chamber, which can effectively reduce the energy transfer indoors and outdoors. The heat preservation effect is good. There is a steel lining chamber inside the profile, and the steel lining inside can effectively enhance the strength of the profile , Greatly improve the bending resistance of the profile, and the cost is low.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Detailed ways:

In the figure, the number 101 represents the profile body, the number 102 represents the steel lining chamber, the number 103 represents the first insulation chamber, the number 104 represents the second insulation chamber, the number 105 represents the first side strip, the number 106 represents the second side strip, and the number 107 represents the As for the installation flaps provided on the first side strip, reference numeral 108 represents the installation flaps provided on the second side strip.

The utility model will be further described in detail below in conjunction with the accompanying drawings and technical solutions, and the implementation of the utility model will be described in detail through preferred embodiments, but the implementation of the utility model is not limited thereto.

Embodiment 1, as shown in Figure 1, a new type of profile for doors and windows, including a profile body, the profile body is provided with a thermal insulation chamber, a steel lining cavity, and two installation mechanisms are provided at the section of the profile body, and the installation mechanism includes the first One side bar, the second side bar and the beam connecting the first side bar and the second side bar, the first side bar and the second side bar are provided with installation hems, which effectively saves manufacturing costs and is securely installed and fixed.

As mentioned above, the installation flange is an installation protrusion, or an "L"-shaped installation edge perpendicular to the first edge and the second edge, and the installation method is more flexible.

As mentioned above, the heat preservation chamber includes a first heat preservation chamber and a second heat preservation chamber, and connecting internal ribs are arranged between the first heat preservation chamber and the second heat preservation chamber, so that the heat preservation effect is better.

As mentioned above, the profile body is made of plastic material.

The utility model adopts plastic profiles, and is fixed and installed through two side bars and the installation folded edges on the side bars. The first thermal insulation chamber and the second thermal insulation chamber can effectively reduce the energy transfer indoors and outdoors, and the thermal insulation effect is good. There is a steel lining cavity inside the profile, and the steel lining inside can effectively enhance the strength of the profile and greatly improve the bending resistance of the profile. low cost.

The utility model is not limited to the above-mentioned specific implementation, and those skilled in the art can also make various changes accordingly, but any equivalent or similar changes to the utility model should be covered within the scope of the claims of the utility model.
