[0002] A structure on the roof of a building that extends beyond the main roof, such as a small attic, equipment room, or decorative structure. Part of the wall of the structure is built under the edge of the roof deck to support the side wall of the structure or serve as a waterproof retaining wall.

[0003] At present, the galvanized steel side formwork used on the edge of the floor deck has a smooth surface, so after plastering directly on the side formwork, the plaster layer is difficult to adhere and easy to fall off. The usual practice is to hang a mesh cloth on the side formwork first, and then perform the plastering operation to enhance the bonding strength between the plaster layer and the side formwork.

[0004] However, it was found in actual application that the plaster layer at the side mold position would still fall off after about a week. Summary of the invention

[0005] In view of this, the present invention provides a side wall node of a roof structure, a construction method of the side wall node and a building to solve the problem that the plaster layer in the side mold area of ​​the floor deck is difficult to adhere to permanently.

[0040] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] The structure on the roof of a building that extends beyond the main roof, such as a small attic, equipment room or decorative structure. Part of the wall of the structure is built below the edge of the roof decking 1 to support the side wall of the structure or serve as a waterproof retaining wall. At present, the galvanized steel side mold used on the edge of the floor decking 1 has a smooth surface, so that after plastering directly on the side mold, the plaster layer is difficult to adhere and easy to fall off. The usual practice is to hang a mesh cloth on the side mold first, and then perform the plastering operation to enhance the bonding force between the plaster layer and the side mold. However, in actual application, it is found that the plaster layer at the side mold position will still fall off after about a week.

[0042] In view of this, the present invention provides a side wall node of a roof structure, a construction method of the side wall node and a building to solve the problem that the plaster layer in the side mold area of ​​the floor decking slab 1 is difficult to adhere to permanently.

[0043] Combine the following Figure 1 , describing an embodiment of the present invention.

[0044] According to an embodiment of the present invention, on the one hand, a side wall node of a roof structure is provided, and the side wall node includes a roof structure, an eave 3, an exterior wall 4 and a plaster layer.

[0045] Specifically, in the embodiment of the present invention, the roof structure is provided with a floor deck 1 and a parapet 2 provided on the floor deck 1. When the parapet 2 around the small roof is constructed, a concrete pouring method is adopted, and in this process, the overhanging eaves 3 are correspondingly extended. The parapet 2 not only plays a protective role, but the eaves 3 can also provide better sunshade and rain shelter effects by extending, thereby increasing the beauty of the building.

[0046] Furthermore, in the embodiment of the present invention, the floor deck 1 is provided with a side formwork at the outer edge. During the construction process, the side formwork can firmly fix the steel truss floor deck 1 to prevent it from shifting and deforming during the construction process such as concrete pouring, and ensure the accurate position of the floor deck 1, thereby ensuring the dimensional accuracy and stability of the entire floor structure.

[0047] Furthermore, in the embodiment of the present invention, the overhanging eaves 3 are arranged on the parapet wall 2 and extend outward. The overhanging eaves 3 extending outward can effectively prevent rainwater from directly washing the wall of the building, reduce the erosion of rainwater on the outer wall 4 of the building, and protect the wall structure and interior decoration from damage by rainwater.

[0048] Furthermore, in an embodiment of the present invention, along the vertical direction, the outer wall 4 is built below the overhanging eaves 3, the bottom of the outer wall 4 is connected to the ground foundation, the top of the outer wall 4 is connected to the overhanging eaves 3, and the outer wall 4 wraps the side formwork inside.

[0049] The connection between the outer wall 4, the ground foundation and the cantilever 3 enables the entire building to form a relatively stable structural system in the vertical direction. The ground foundation provides solid support for the outer wall 4, and the cantilever 3 plays a certain restraining role on the outer wall 4 from above, jointly ensuring the stability of the building. At the same time, wrapping the side mold with the inner outer wall 4 can provide certain protection for the side mold, reduce the impact of external factors on the side mold, such as preventing the side mold from being directly hit by external forces, erosion by wind and rain, etc., thereby extending the service life of the side mold.

[0050] Furthermore, in the embodiment of the present invention, the plaster layer is applied on the outer wall 4. In the actual construction process, after the wall is built, the surface of the outer wall 4 is plastered, that is, cement mortar or other special materials are applied to obtain a smooth wall surface. Plastering is also very important for improving the appearance quality of the building and protecting the wall from erosion by the external environment.

[0051] In this way, the embodiment of the present invention builds the outer wall 4 under the overhanging eaves 3 and wraps the side formwork inside, so that the overall outer wall is the masonry wall, and the construction workers can directly perform plastering operations on the outer wall 4. Compared with plastering on the galvanized metal side formwork, the plastering effect on the outer wall 4 is better, thereby solving the problem that the plaster layer in the side formwork area of ​​the floor deck 1 is difficult to adhere to for a long time.

[0052] Furthermore, in an optional embodiment, the inner side of the outer wall 4 fits with the outer side of the side mold and the outer side of the parapet 2. In other words, the end face of the outer wall 4 facing away from the outside fits with the end face of the side mold close to the outside and the end face of the parapet 2 close to the outside.

[0053] With such a configuration, the embodiment of the present invention fits the inner side of the exterior wall 4 with the outer side of the side mold and the outer side of the parapet 2, which helps to form a continuous waterproof barrier and reduce the possibility of rainwater penetration. The parapet 2 is located at the top of the exterior wall 4 and can effectively prevent rainwater from directly flowing into the wall. The side mold ensures the sealing of the wall, and together improves the waterproof effect of the building. In addition, the integrated structure of the parapet 2 and the exterior wall 4 can enhance the stability of the top of the wall and effectively prevent the top of the wall from being damaged or falling off due to uneven force.

[0054] Furthermore, in an optional embodiment, the depth of the eaves 3 is greater than the thickness of the exterior wall 4 .

[0055] In this way, the depth of the eaves 3 in the embodiment of the present invention is greater than the thickness of the outer wall 4, that is, the eaves 3 is protruding from the outer wall 4. In this way, rainwater can be further blocked from directly flowing into the wall, thereby improving the waterproof effect of the building and avoiding the risk of rainwater leakage.

[0056] Furthermore, in an optional embodiment, the exterior wall 4 also includes structural columns and walls.

[0057] Specifically, in the embodiment of the present invention, along the vertical direction, the structural column is arranged below the overhanging eaves 3. The bottom of the structural column is connected to the ground foundation, and the top of the structural column is connected to the overhanging eaves 3. A plurality of structural columns can be arranged, and those skilled in the art can change them according to actual conditions. This embodiment is not limited to this, and the same technical effect can be achieved.

[0058] Furthermore, in an embodiment of the present invention, the wall is built along the structural column and is tightly combined with the structural column. The wall wraps the side formwork inside.

[0059] Furthermore, in an optional embodiment, the side wall node further includes a structural beam 5 , which is arranged in a horizontal direction, and the top of the structural beam 5 abuts against the floor decking plate 1 .

[0060] Furthermore, in an optional embodiment, the outer side edge of the structural beam 5 is flush with the outer side edge of the side form.

[0061] Further, in an optional embodiment, the side wall node further comprises a load-bearing column, and the load-bearing column is arranged along the vertical direction. One end of the structural beam 5 abuts against the structural beam 5, and the other end of the structural beam 5 abuts against the ground foundation.

[0062] In a second aspect, the present invention further provides a construction method for a side wall node of a roof structure, the construction method comprising:

[0063] S1. Build the parapet wall 2 of the roof structure;

[0064] S2, constructing an overhanging eave 3 on the parapet 2, and extending the overhanging eave 3;

[0065] Specifically, when constructing the parapet wall 2 around the roof of the small house, a concrete pouring method is adopted, and in this process, the overhanging eaves 3 are correspondingly extended.

[0066] S3, building an outer wall 4 below the overhanging eaves 3, with the bottom of the outer wall 4 connected to the ground foundation, and the top of the outer wall 4 connected to the overhanging eaves 3, so that the outer wall 4 wraps the side formwork inside;

[0067] This step is to carry out the masonry work of the side walls, usually using bricks or blocks, and at the same time build structural columns to strengthen the stability and load-bearing capacity of the wall. Structural columns are vertical load-bearing structures in buildings and are essential to maintaining the structural safety of the entire building.

[0068] S4, plastering the outer side of the exterior wall 4 to form a plaster layer.

[0069] After the wall is built, the surface of the outer wall 4 is plastered, that is, cement mortar or other special materials are applied to obtain a flat wall surface to prepare for subsequent decoration work, such as coating, tile pasting, etc. This process is also very important for improving the appearance quality of the building and protecting the wall from erosion by the external environment.

[0070] Further, in an optional embodiment, building the outer wall 4 below the overhanging eaves 3 includes:

[0071] S31, constructing the structural columns of the outer wall 4 below the overhanging eaves 3;

[0072] S32, building a wall along the structural column and wrapping the side formwork inside.

[0073] In the actual construction process, the architectural design drawings can be confirmed first to clarify the exact position and size of the exterior wall 4 and the structural column. Then use a measuring tool such as a theodolite to mark the position line of the structural column below the cantilever 3 to ensure the accuracy of the position. Tie the structural column reinforcement cage according to the marked position, including the foundation reinforcement and the vertical reinforcement, to ensure that the arrangement of the reinforcement meets the design specifications. Then support the structural column formwork, and at the same time ensure that the formwork is stable and the verticality meets the requirements. Pour concrete into the structural column formwork.

[0074] Furthermore, during the curing of the structural column, the side formwork of the wall is prepared and fixed to the predetermined position inside the structural column according to the design requirements to ensure the precise alignment of the structural column and the future wall. Then the wall is built along the structural column to ensure that the wall is tightly combined with the structural column, and the side formwork is wrapped inside to achieve a flat inner wall surface. During the masonry process, tie bars are set according to the design requirements to strengthen the connection between the wall and the structural column. After the wall is built, the verticality and flatness of the wall are checked and any unevenness is corrected.

[0075] In a third aspect, the present invention further provides a building, comprising: a side wall node of a roof structure as described in any one of the above embodiments.

[0076] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
