Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of old building renovation, and specifically belongs to the window side keel structure in old wall renovation. Background Art
[0002] There are a large number of old buildings in China, with various structural forms and uneven project qualities. Cracking and peeling of the insulation layer occur frequently, seriously affecting the normal living order of the people. With the gradual improvement of China's building energy efficiency standards, the energy-saving renovation of old buildings is imperative. The original thickness of the insulation layer has seriously lagged behind the requirements of the new building energy efficiency standards, and secondary renovation is an urgent task at this stage, otherwise it will affect the realization of the overall goal of China's carbon emissions.
[0003] During the current old house renovation process, insulation wall panels need to be fixedly installed on the outer wall near the window of the household. However, since the window is recessed inward relative to the outer wall, there is no object in contact with the side of the insulation wall panel close to the window, and sealant needs to be applied for connection and fastening, and the side of the insulation wall panel needs to be sealed. However, after installation in this way, the insulation wall panel near the window is not firm enough. Summary of the Utility Model
[0004] In view of this, the purpose of the utility model is to overcome the deficiencies in the prior art and provide a window side keel structure in old wall renovation. The present application provides the following technical solutions:
[0005] It includes a window side keel anchored on the inner peripheral side walls of the window, and a horizontal keel and a vertical keel anchored on the outer peripheral outer walls of the window. An extension part extending outside the window for connecting wall panels is provided on the window side keel. The vertical keel is screwed to the horizontal keel to form a grid-like structure, and the window side keel is screwed to the horizontal keel or the vertical keel.
[0006] By anchoring the window side keel on the inner peripheral side walls of the window, and anchoring the horizontal keel and the vertical keel on the outer peripheral outer walls of the window, a framework is formed after the horizontal keel, the vertical keel and the window side keel are connected, and the insulation wall panel installed in the framework is more firm.
[0007] The window side keel is in a T shape, and includes a fixing plate for anchoring with the inner side wall of the window, a bearing plate extending out of the window for connecting the wall panel on the outer wall, and a connecting plate for connecting and screwing with the horizontal keel or the vertical keel.
[0008] The window side keel is divided into orientations: a window top keel anchored at the top of the window, a window side keel anchored on both sides of the window, and a window bottom keel anchored at the bottom of the window; the window top keel is screwed to the vertical keel on the outer wall above it, the window side keel is screwed to the horizontal keel on the outer wall outside it, and the window bottom keel is screwed to the vertical keel below it.
[0009] The end surface of the top of the window side keel is closely attached to the lower surface of the end of the window top keel, and the inner side surface of the bottom of the window side keel is closely attached to the end surface of the end of the window bottom keel.
[0010] Through the above arrangement, on rainy days, when rainwater flows through the top of the window top keel, it flows directly to the outside of the window side keels from both sides thereof, and is not easy to flow into the gap between the window top keel and the window side keel, thereby reducing rainwater erosion.
[0011] The transverse keel is in an I-shape, and the middle part is a transverse bearing part, and the two ends of the transverse bearing part are respectively vertically provided with a transverse connecting part and a transverse clamping part; the vertical keel is in an I-shape, and the middle part is a vertical bearing part, and the two ends of the vertical bearing part are respectively vertically provided with a vertical connecting part and a vertical clamping part, the transverse connecting part is anchored to the exterior wall, and the vertical connecting part has a vertical installation part extending along the axial direction of the vertical keel, and the vertical installation part is screwed on the transverse connecting part.
[0012] The transverse connecting portion has a transverse mounting portion extending along the axial direction of the transverse keel, the connecting plate on the window side keel is screwed to the transverse mounting portion of the transverse keel on the outer wall thereof, the connecting plates on the window top keel and the window bottom keel are also anchored to the outer wall, the vertical mounting portion of the vertical keel above the window top keel is screwed to the connecting plate of the window top keel, and the vertical mounting portion of the vertical keel below the window bottom keel is screwed to the connecting plate of the window bottom keel.
[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0014] The window keel can be anchored and installed between the original windows without removing the wall panel at the original window. After anchoring the window keel, the bearing plate on the window keel is abutted against the side of the insulation wall panel installed on the exterior wall to play a bearing role, and then glue is applied to seal it. The insulation wall panel on the exterior wall next to the window will be more secure after installation.

[0032] The horizontal keel 2 is in an I shape, with a horizontal bearing part 21 in the middle. At both ends of the horizontal bearing part 1, a horizontal connecting part 22 and a horizontal engaging part 23 are respectively vertically provided; the vertical keel 3 is in an I shape, with a vertical bearing part 31 in the middle. At both ends of the vertical bearing part 31, a vertical connecting part 32 and a vertical engaging part 33 are respectively vertically provided. The horizontal connecting part 22 is anchored to the outer wall of the building, and the vertical connecting part 32 extends axially along the vertical keel 3 to have a vertical installation part 321, and the vertical installation part 321 is screwed to the horizontal connecting part 22.

The connecting plate 13 on the window-side keel 1b is screwed and fixed on the transverse installation part 221 of the transverse keel 2 on the outer wall outside it. The connecting plates 13 on the window-top keel 1a and the window-bottom keel 1c are also anchored to the outer wall. The vertical installation part 321 of the vertical keel 3 above the window-top keel 1a is screwed and fixed on the connecting plate 13 of the window-top keel 1a. The vertical installation part 321 of the vertical keel 3 below the window-bottom keel 1c is screwed and fixed on the connecting plate 13 of the window-bottom keel 1c.
[0034] During specific implementation, first anchor the transverse keel 2 on the outer wall, drill holes in the transverse connection part 22 and the outer wall, then use expansion bolts to pass through the holes to anchor the transverse keel 2 on the outer wall, and then install the window-top keel 1a and the window-bottom keel 1c. During installation, anchor the fixing plate 11 of the window-top keel 1a and the window-bottom keel 1c to the inner side wall of the window opening, and anchor the connecting plates 13 of the window-top keel 1a and the window-bottom keel 1c to the outer wall.
