Problems solved by technology

However, when there are ridges or grooves on the vertical profile 2', the rubber pad 4' still cannot fully fit the profile, resulting in large water seepage gaps, and the waterproof performance is still unsatisfactory.
[0005] In addition, the above two connection structures are only reinforced by the connection section 11' of the horizontal profile 1' and the vertical section 2'. The connection section is linear, the reinforcement effect is poor, and the connection is not firm.

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] Such as image 3 , Figure 4 A connection piece with a cavity profile is shown, which is used for the connection between the metal horizontal profile 1 (such as the sliding of the door and window, the lower middle waist) and the metal vertical profile 2 (such as: the frame of the door and window), the horizontal profile 1 A cavity with a sealed section is provided along the length direction.

[0034] The connecting piece is a block-shaped plastic hollow piece whose outer contour is adapted to the cavity so as to be embedded in the cavity. It includes upper and lower two insertion surfaces 41 and two insertion surfaces perpendicular The bonding surface 42 of 41, described bonding surface 42 is made up of inner end face and outer end face, all forms boss 44 on inner end face, outer end face, and the height of boss 44 is 1cm, and the oute...

Abstract

The invention discloses a connecting piece with a cavity sectional material, and solves the defects that the connection of a connecting structure between the existing horizontal sectional material and the vertical sectional material is not firm and the water-proof property is poor. According to the technical scheme, the connecting piece provided by the invention is of a block shape, the outer shape of the connecting piece is matched with a cavity of the sectional material, so that the connecting piece is conveniently placed in the cavity, and the connecting piece comprises at least one inserting surface and a bonding surface which is perpendicular to the inserting surface. The connecting piece provided by the invention has the advantages that the block-shaped connecting piece arranged in the cavity of the horizontal sectional material is used for changing the line connection of a gluing position arranged among the sectional materials into surface connection, the connecting strength is effectively improved, a glue is subjected to extrusion so as to flow from inside to outside so as to rapidly and effectively fill a gap caused by the lower machining precision or sectional material specific structure requirement, the gap after solidifying is blocked, and the waterproof property is good.

Description

technical field [0001] The invention relates to the field of metal profiles for construction, in particular to a connector with cavity profiles. Background technique [0002] During the processing and assembly of profiles for doors and windows, there is often a structure in which horizontal profiles are connected to vertical profiles. [0003] At present, the connection structure between profiles is generally as follows: figure 1 As shown, after the connection section 11' of the horizontal profile 1' is offset against the side of the vertical profile 2', it is directly locked with the screw 3', and then a special adhesive is applied on the outer contour of the connection section 11' for reinforcement and sealing. water proof. This connection structure has high requirements on the processing accuracy of the profiles, especially the connection section 11' of the horizontal profile 1'. If the connection section 11' is not smooth, the connection structure will be loose and swi...
