The technical scheme of the invention mainly surrounds a core design thought of 'realizing hidden design of a building system', is improved comprehensively from the aspects of beam-wall connection, column-wall connection, supporting force component 'steel beam column wall' structure, column foot nodes and the like, and the whole building system design can realize the 'hidden' function through multi-means joint coordination design.
The invention mainly considers the rationality of space layout in design, and does not expose the beam column in the indoor space, therefore, in the embodiment, the steel pipe concrete column with rectangular section is selected as the column body 1, and the width of the narrow-side connecting surface of the column body 1 is required to be smaller than the thickness of the wall body 6 in the base layer, so that the column body is ensured not to be exposed when the two are connected. It is known to use square cross section columns of larger size as supports in conventional construction, based on load bearing design considerations, but with the exposed columns taking up a larger indoor space. The bearing capacity index of the column 1 with the rectangular section adopted by the invention can be met by adjusting the width of the surface where the long side of the column 1 is positioned. In this embodiment, the connection between the column 1 and the base layer inner wall 6 or the enclosure outer wall 5 is shown in fig. 5C-1 and 5C-2. The column 1 has four connection surfaces, and is generally divided into a straight node, an L-shaped node, a T-shaped node and a cross-shaped node according to the shape design of the connection nodes in the current building, and fig. 5C-1 and 5C-2 only show two representative T-shaped nodes, and the connection modes of other nodes can be carried out by referring to the same content of the T-shaped nodes, so that the drawing is omitted. At least two connecting surfaces are required to be connected with a wall body in the construction process, and the surface of the narrow side of one side of the column body 1 is required to be connected with the wall body. The base layer inner wall body in the embodiment is usually used as a building inner partition wall, and can be built by building blocks or assembled by assembling battens.
When the two narrow sides of the column 1 are respectively connected with the inner walls 6-1 and 6-3 of the base layer, the column 1 is required to be placed in the middle of the connecting end of the inner wall 6 of the base layer, after the fixed connection of the column 1 and the wall is completed according to the existing connecting mode, fireproof coatings are respectively arranged on the outer surfaces of the long sides of the two sides of the column 1, and the fireproof coatings on the two sides of the column 1, together with the sum of the widths of the narrow sides of the column 1, are equal in thickness with the inner wall 6 of the base layer. When the surface of the long side of the column body 1 is connected with the wall body 6 in the base layer, two setting positions exist according to the situation of the building pattern, one of the setting positions is to center the wall body 6-2 in the base layer on the surface of the long side of the column body 1, and a T-shaped node shown in fig. 5C-1 is formed. After the column 1 is connected with the inner wall of the base layer according to the structure, galvanized steel wire meshes 17 are respectively paved at the junctions of the outer surfaces of the two sides of the connecting surface of the column 1 and the inner wall of the base layer, one end of each steel wire mesh 17 is tied and fixed on the surface of the column 1, the other end of each steel wire mesh 17 is tied and fixed on the surface of the wall of the base layer, and a plastering mortar leveling layer 20 is arranged outside each steel wire mesh 17. The laying of the steel wire mesh 17 plays a reinforcing role at the joint, and the joint surface can be prevented from cracking. As shown in FIG. 5C-2, the connection mode of the long side connection surface of the column 1 and the wall body is the same as that of the connection mode of the narrow side of the column 1 and the base layer inner wall body 6-4, the outer side surfaces of the 5-1 and 5-2 serving as enclosure outer walls are flush with the surface of the outermost narrow side of the column 1, and thus the T-shaped node is formed, and the heat-insulating waterproof layer 22 is arranged on the outer side to serve as the outer wall body.
The girder steel in this embodiment adopts H shaped steel girder steel 2, and the width of the edge of a wing of H shaped steel girder steel needs to be less than the thickness of basic unit's interior wall body 6, is convenient for make level girder steel 2 and wall body and arrange the pipeline like this. When the steel beam 2 is connected with the basic-level inner wall 6, as shown in fig. 4B-1, the H-shaped steel beam 2 is arranged on the upper end surface of the basic-level inner wall 6 in the middle, and after the H-shaped steel beam 2 is fixedly connected with the basic-level inner wall 6 in the existing fixing manner, the cavities on two sides of the web of the H-shaped steel beam 2 are filled with filler 19. The steel mesh 17 is arranged on the outer side of the web plate of the H-shaped steel beam 2 to prevent slurry from overflowing, the lower part of the steel mesh 17 extends to the surface of the wall body 6 in the base layer, the lower part of the steel mesh 17 is fixedly tied with the wall body 6 in the base layer, and the upper part of the steel mesh 17 can be fixed at the bottom of the concrete floor 4 at the top of the upper flange of the H-shaped steel beam 2 by steel nails. In order to realize the flush of the steel beam 2 and the wall surface, a plastering mortar layer is further required to be arranged from the outer side of the steel mesh 17 to the surface of the base inner wall 6 to serve as a leveling layer 20, and the leveling layer 20 can enable the H-shaped steel beam 2 to be kept flush with the outer surface of the base inner wall 6. If the pipeline 18 is required to be laid on the wall, the pipeline 18 needs to be hidden inside the wall for aesthetic purposes, namely: when the pipeline 18 is routed along the H-shaped steel beam 2 and the basic-layer inner wall 6, the pipeline 18 penetrates into the basic-layer inner wall 6 along the side gap of the flange of the H-shaped steel beam 2, the pipeline 18 is routed on the inner side of the steel mesh 17 by utilizing the gap between the flange of the steel beam 2 and the basic-layer inner wall 6, and the outer side of the steel mesh 17 is leveled by the leveling layer 20, so that the hiding of the pipeline 18 is realized, and bending is not required at the joint of the steel beam 2 and the basic-layer inner wall 6. Considering that the steel beam 2 needs to be connected with the outer wall body sometimes, as shown in fig. 4B-2, the connection can still be completed according to the structure given above by connecting the web plate of the H-shaped steel beam 2 with one side of the inner wall body, and the cavity outside the wall body can be filled with the cast-in-place concrete layer 21 to form the outer wall body, and the cast-in-place concrete mode can realize the required shape according to the design structure of the outer wall body.
For the steel frame-support structure system building, the existing steel tube bundle combined shear wall can realize a good side stiffness resisting effect, but the matching performance of the steel tube bundle combined shear wall and other connecting members is poor, the purpose that the support members are hidden in the wall cannot be realized, and the steel tube bundle combined shear wall is not beneficial to the arrangement of pipelines. Therefore, the invention adopts the steel beam column wall 3 structure on the aspect of improving the side force resistance of the building, can meet the side force resistance design requirement, is matched with other prefabricated components of the invention on connection, jointly realizes the hiding effect, and can integrate the support function of the column and the beam and the function of the enclosure wall.

The edge column 301 may be a steel pipe with a rectangular section, and if the steel pipe is a hollow steel pipe, whether concrete is poured inside the steel pipe may be selected according to the design requirement of the bearing capacity; or steel columns with H-shaped steel or T-shaped steel can be selected as the sections; the two end edge posts 301 may also be selected from different types of steel mix combinations, as shown in fig. 6-3, and the free matching of the two end edge posts 301 may be: one end is a rectangular steel pipe, and the other end is an H-shaped steel column; or one end is a rectangular steel pipe, and the other end is a T-shaped steel column; or one end is an H-shaped steel column, and the other end is a T-shaped steel column. When the selected steel column is provided with H-shaped steel or T-shaped steel, concrete or light filling materials are poured into cavities at two sides of the steel web plate. The supporting beam 302 adopts H-shaped steel, the installation position of the supporting beam 302 is required to correspond to the height position of the steel beam 2 used in the whole steel frame system building, and the width of the flange of the steel beam 2 is not greater than the width of the connecting surface at the outer side of the edge column 301. The bracing member 303 is a solid web-shaped cross-section member, such as: angle steel, channel steel, bar steel plate, etc. The bracing rods 303 may be arranged diagonally alternately as shown in fig. 6-1, or may be arranged in the horizontal direction (the drawing is omitted).
In order to facilitate the pipe penetrating construction operation of the later-stage equipment pipeline, the cross-sectional width of the supporting beam 302 in the embodiment is not larger than the width of the connecting surface of the edge posts 301, and the cross-sectional width of the bracing rod 303 is also not larger than the width of the connecting surface of the edge posts 301, so that after the combined connection, a certain space is reserved between the supporting components between the edge posts 301 and the outer surface of the edge posts 301, and the space is filled with the filling material 304, thereby leaving an operation space for the equipment junction box to be perforated or the pipe to be penetrated. After the combination is completed in a factory according to the structure, steel nets 305 are respectively paved on two sides of the supporting beam 302, wherein the steel nets 305 can be steel wires or steel plates, and finally filling materials 304 are poured between the edge columns 301 at two ends, so that the filling materials 304 can completely hide the supporting beam 302 and the bracing rods 303 which are positioned between the edge columns 301 at two ends, the filling materials 304 can be light filling materials, concrete can be used for pouring and filling, and the steel nets 305 play a role in preventing the filling materials from cracking. When the surfaces of the edge posts 301 at the two ends do not need to be provided with a fireproof coating, as shown in fig. 6-2, the total thickness of the filled filler 304 is kept to be equal to the width of the connecting surface of the edge posts 301; if the surface of the edge column 301 needs to be provided with a fireproof coating, the total thickness of the filled filler 304 needs to be greater than the width of the connecting surface of the edge column 301, and the total thickness of the filled filler 304 is equal to the sum of the width of the connecting surface of the edge column 301 and the thickness of the fireproof coating.
