Description

Technical Field

[0001] The utility model belongs to the technical field of old building renovation, and specifically belongs to the keel structure at the position of the ring beam in the renovation of old walls. Background Technique

[0002] Problems such as peeling, cracking, water seepage and degradation of thermal insulation performance are common in the outer walls of old buildings, which not only affect the city appearance and the living environment of the people, but also do not meet the energy-saving requirements of green and low-carbon; therefore, the renovation of the roofs and facades of old buildings has a broad market space; especially for the renovation of the roof, it is extremely urgent. The aging of the roof energy-saving and waterproof functions reduces the living experience of the top-floor owners. More importantly, once heavy rain causes water accumulation and snow accumulation on the roof; the load of water accumulation and snow accumulation exceeds the load requirement of the roof slab and will also cause damage to the structure, and sometimes may lead to safety accidents.

[0003] The ring beam of the house plays a very important load-bearing role. During the renovation of the outer facade of the old building, in order to ensure the bearing strength of the ring beam, it is not possible to drill holes in the ring beam to install anchor bolts. When fixing the new outer facade at the position of the ring beam, there are certain difficulties. Content of the Utility Model

[0004] In view of this, the purpose of the present utility model is to overcome the deficiencies in the prior art and provide a keel structure at the position of the ring beam in the renovation of old walls. The present application provides the following technical solutions:

[0005] It includes a ring beam, and basic walls located above and below the ring beam; several vertical keels are arranged on the outer surface of the ring beam, and both ends of the vertical keels extend out of the orthographic projection range of the ring beam and are anchored to the basic walls through anchor bolts; a mesh cloth layer is fixed on the outer surfaces of the ring beam and the basic walls between the vertical keels, and several horizontal keels are also arranged between the vertical keels. Both ends of the horizontal keels are fixedly connected to the vertical keels, and the middle part is closely attached to the mesh cloth layer to press the mesh cloth layer.

[0006] On the outer surface of the mesh cloth layer, a mortar layer and a decorative layer are also plastered and painted from the inside to the outside.

[0007] The horizontal keels are located within the orthographic projection range of the basic walls, and the middle part of the horizontal keels is anchored to the basic walls. The installation of the horizontal keels is more firm.

[0008] The mesh cloth layer includes mesh cloth and an adhesive. The adhesive bonds a whole piece of the mesh cloth to the outer surfaces of the ring beam and the basic walls between the vertical keels to form the mesh cloth layer.

[0009] The vertical keel includes a main rod portion and a fixing portion. The fixing portion is located on one side of the main rod portion and contacts the ring beam and the outer surface of the base wall. Through holes are provided on the fixing portion for passing through anchor bolts to anchor with the base wall and for connecting the horizontal keel.

[0010] The horizontal keel includes a connecting portion and a bearing portion. The connecting portion and the bearing portion are perpendicularly arranged. Through holes are provided on the connecting portion. At both ends, self-tapping screws pass through the through holes on the connecting portion and the fixing portion and drill into the base wall to fix the horizontal keel. An anchor bolt is passed through the through hole in the middle of the connecting portion to anchor with the base wall. A drip groove is provided below one end of the bearing portion far away from the connecting portion.

[0011] The surface of the decorative layer is flush with the end face of the bearing portion where the drip groove is provided. Making the end face of the bearing portion serve as a decorative line for the surface of the decorative layer is more beautiful.

[0012] The mortar layer is formed by brushing and curing modified vitrified microbead lightweight mortar on the mesh cloth layer. Modified vitrified microbead lightweight mortar is light in weight, has good adhesiveness, and is not easy to fall off from the mesh cloth layer.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows: By anchoring the vertical keel with the base walls above and below the ring beam, then pressing the mesh cloth layer by setting the horizontal keel, and cooperating with the adhesive on the mesh cloth layer, even without drilling holes in the ring beam to set anchor bolts, the mesh cloth layer can be firmly located on the outer surface of the ring beam. Then, through the bonding effect of the adhesive on the mesh cloth layer, the installation of the new outer facade at the ring beam is realized.
