The window frame holder
Technical field
The utility model relates to a kind of window frame holder.
Background technology
Common window frame and window reserving hole structure wall are directly fixed, and fill with common plugging material in the slit between window frame and the window reserving hole structure wall.Because window frame limit area makes in the cavity of window frame limit can't disposable shutoff closely knit greatly; And can cause window frame at other operation work progress and reason such as to scratch, cause easily to occur the crack between window frame and stuff up a crack, and cause serious window limit infiltration; Repair and need carry out secondary, influence efficiency of construction.
Summary of the invention
The purpose of the utility model is to provide a kind of window frame holder; It can realize firm combining with window reserving hole structure wall in advance; Not only avoid producing loosening crack, and can install and fix with window frame quickly and easily, improve efficiency of construction because of other operation construction infection.
The purpose of the utility model realizes through following technical scheme: a kind of window frame holder is characterized in that: it comprises that being installed on being used on the window reserving hole structure wall is connected fixing secondary framework, is connected in the civil engineering rendering layer that installing and fixing assembly, being filled in the anticracking grout layer between secondary framework and the window reserving hole structure wall and being coated on the anticracking grout layer outside, the secondary framework left and right side frame outside and the window reserving hole structure wall outside between secondary framework and the window reserving hole structure wall with window frame.
The method for using of the utility model is following: when the window frame holder is installed; Earlier secondary framework is fixedly installed on the window reserving hole structure wall through installing and fixing assembly; Then the filling of the slit between secondary framework and the window reserving hole structure wall is closely knit with anticracking grout; Apply the civil engineering rendering layer afterwards, the window frame holder is installation.Because the window frame holder is realized firm combining with window reserving hole structure wall, therefore can avoid producing loosening crack because of other operation construction infection.In the time will window frame being installed; Only need window frame is connected fixing (the cavity filled with foaming material inside that between window frame and window frame holder, forms as required) through self-tapping screw with secondary framework, window frame got final product with the fluid sealant shutoff with being connected between the slit of window frame holder.
Compared to prior art, therefore the utility model has the following advantages owing on window reserving hole structure wall, the window frame holder is set:
(1) the window frame holder can be realized firm combining with window reserving hole structure wall in advance, not only avoids producing loosening crack because of other operation construction infection, and the phenomenon that prevents to seep water produces, and can install and fix with window frame quickly and easily.
(2) can avoid window frame directly to install and be connected, not only help improving installation rate, simplify installation difficulty, and not produce with other operation and to influence each other, improve efficiency of construction greatly with window reserving hole structure wall.

The specific embodiment
Below in conjunction with Figure of description and embodiment the utility model content is elaborated:
Be illustrated in figure 1 as the embodiment sketch map of a kind of window frame holder that the utility model provides.
A kind of window frame holder is characterized in that: it comprises that being installed on being used on the window reserving hole structure wall 1 is connected fixing secondary framework 3, is connected in the civil engineering rendering layer 5 that installing and fixing assembly, being filled in the anticracking grout layer 4 between secondary framework 3 and the window reserving hole structure wall 1 and being coated on anticracking grout layer 4 outside, the secondary framework 3 left and right side frames outside and window reserving hole structure wall 1 outside between secondary framework 3 and the window reserving hole structure wall 1 with window frame 2.
Said secondary framework 3 is the steel frame.
The said assembly that installs and fixes comprises the nailing 7 that is welded in a plurality of fixed iron pieces 6 on secondary framework 3 outer rim and is used for fixed iron piece 6 is fixedly connected with window reserving hole structure wall 1.
