Abstract
Description
Technical Field
[0001] This application relates to the field of building engineering technology, and in particular to a keel partition wall entrance door installation structure. Background Technology
[0002] Light steel keel gypsum board partitions have been widely used in building decoration projects. Their simple structure and convenient construction greatly shorten the construction period. At the same time, they are widely praised in the industry for their versatility. However, due to their inherent characteristics, some quality defects have also occurred at some installation nodes. When installing an entrance door on a light steel keel gypsum board partition, due to the connection method between the door and the partition and the structural characteristics of the lightweight partition (especially for entrance doors with door closers), problems such as cracking at the connection between the door frame and the wall and sagging of the entrance door have occurred during long-term use. These problems make subsequent repairs difficult and costly.

[0021] Example
[0022] In order to solve the problems in the existing technology (reference) Figure 1 (As shown) Installing an entrance door on a light steel keel gypsum board 110 can easily lead to problems such as cracking of the door frame 120 and sagging of the door. (Refer to...) Figure 2 and Figure 3 As shown, this application discloses a keel partition wall entrance door installation structure, including a top and bottom keel 10, a plurality of vertical keels 20, and a plurality of horizontal keels 30; the top and bottom keels 10 are fixed to the bottom of the building roof slab 50, the plurality of vertical keels 20 are arranged below the top and bottom keels 10 and the building floor slab 60 to form a doorway 40, the plurality of horizontal keels 30 are connected between the plurality of vertical keels 20 in areas other than the doorway 40, and gypsum board 110 is installed on the plurality of vertical keels 20 and the plurality of horizontal keels 30 in areas other than the doorway 40, and two vertical keels 30 on each side of the doorway 40 are connected to the doorway 40. Above the keel 20, square tube keels 70 are obliquely fixed to the top and bottom keels 10, and the two square tube keels 70 form a triangular structure. On both sides of the door opening 40, two vertical keels 20 are opposite each other and door frames 120 are provided. A single door 130 is provided between the two door frames 120. Based on the above structure, the two square tube keels 70 forming a triangular structure can play a stabilizing role. Even when the single door 130 is operated for a long time, the door frame 120 will not crack or the entrance door will sink, avoiding high-cost maintenance later and having high use value.
[0023] In order to ensure a tight connection between the top and bottom joists 10 and the vertical joists 20 and the building top slab 50 and the building bottom slab 60, this application provides rubber pads 80 on both the building top slab 50 and the building bottom slab 60. In order to achieve a flame-retardant effect for the door frame 120 and prevent the single door 130 from catching fire in the event of a fire, this application provides a flame-retardant board base layer 140 between the door frame 120 and the vertical joists 20.
[0024] In one specific implementation, the top and bottom keels 10 of this application are fixed to the building roof slab 50 by the first expansion bolt 90, the several vertical keels 20 are fixed to the building roof slab 50 and the building floor slab 60 by the second expansion bolt 100, and the several horizontal keels 30 are welded to the several vertical keels 20.
[0025] In a preferred embodiment, the door frame 120 of this application is a wooden door frame 120, and the single door 130 is a wooden single door 130. The door frame 120 and the single door 130 made of this material are lightweight and have little impact on the overall structure when used.
