In the design, the reasonability of space layout is mainly considered, and the beams and columns are not exposed in the indoor space, so that the steel pipe concrete column with the rectangular section is selected as the column body 1 in the embodiment, 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 not exposed when the two are connected. It is known that in conventional buildings, square-section columns with larger sizes are used as supports, which is based on the design requirement of bearing capacity, but the exposed columns occupy larger indoor space. The bearing capacity index of the column body 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 body 1 is located. The connection of the column 1 in this embodiment with the base inner wall 6 or with the exterior enclosure wall 5 is shown in fig. 5C-1 and 5C-2. The column body 1 is provided with four connecting surfaces, and is generally divided into a straight node, an L-shaped node, a T-shaped node and a cross node according to the shape design of the connecting nodes in the current building, only two representative T-shaped nodes are shown in figures 5C-1 and 5C-2, the connecting modes of other nodes can be performed by referring to the same contents of the T-shaped nodes, and the figures are omitted. In the construction process, at least two connecting surfaces are required to be connected with the wall body, and the surface of the narrow edge on 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 formed by combining assembled battens.
When the surfaces of two narrow sides of the cylinder 1 are respectively connected with the base layer inner wall bodies 6-1 and 6-3, the cylinder 1 needs to be arranged at the middle position of the connecting end of the base layer inner wall body 6, after the fixed connection of the cylinder 1 and the wall body is completed according to the existing connection mode, the outer surfaces of the long sides of the two sides of the cylinder 1 are respectively provided with a fireproof coating, and the fireproof coatings on the two sides of the cylinder 1 and the width sum of the narrow sides of the cylinder 1 are equal to the thickness of the base layer inner wall body 6. When the surface of the long edge of the column body 1 is connected with the inner wall body 6 of the base layer, two setting positions are provided according to the building pattern situation, wherein one setting position is to arrange the inner wall body 6-2 of the base layer in the center of the surface of the long edge of the column body 1 to form a T-shaped node as shown in figure 5C-1. After the cylinder 1 is connected with the base layer inner wall body according to the structure, galvanized steel wire meshes 17 are respectively laid at junctions of outer surfaces of two sides of the connection surface of the cylinder 1 and the base layer inner wall body, one end of each steel wire mesh 17 is fixed on the surface of the cylinder 1 in a pulling mode, the other end of each steel wire mesh 17 is fixed on the surface of the base layer inner wall body in a pulling mode, and a plastering mortar leveling layer 20 is arranged on the outer side of each steel wire mesh 17. The steel wire mesh 17 is laid at the joint to play a role in strengthening, and the joint surface can be prevented from cracking. As shown in FIG. 5C-2, the connection between the long-side connection surface of the column body 1 and the wall body is also another way, as described above, the connection between the narrow side of the column body 1 and the base inner wall body 6-4 is the same as that described above, the outer side surfaces of the 5-1 and 5-2 serving as the exterior wall and the outermost narrow side of the column body 1 are arranged in parallel, so that T-shaped joints are formed, and the heat-insulating and waterproof layer 22 is arranged on the outer side of the T-shaped joints and can be used as the exterior wall body.
The girder steel in this embodiment adopts H shaped steel girder steel 2, and the edge of a wing width of H shaped steel girder steel needs to be less than the thickness of wall body 6 in the base layer, is convenient for make level and arrange the pipeline with girder steel 2 and wall body like this. When the steel beam 2 is connected with the base layer inner wall body 6, as shown in fig. 4B-1, the H-shaped steel beam 2 is arranged in the middle of the upper end surface of the base layer inner wall body 6, and after the H-shaped steel beam 2 is fixedly connected with the base layer inner wall body 6 in the existing fixing mode, the cavities on two sides of the web plate of the H-shaped steel beam 2 need to be filled with fillers 19. Set up steel mesh 17 in the H shaped steel girder 2 web outside and block that the thick liquids spills over, steel mesh 17 lower part extends to the interior wall body 6 surface of basic unit to make the lower part of steel mesh 17 and the interior wall body 6 drawknot of basic unit fix, the concrete floor 4 bottom at H shaped steel girder 2 upper flange top can be fixed with the steel nail in the upper portion of steel mesh 17. In order to realize the parallel and level of girder steel 2 and wall, still need set up the mortar layer of plastering as screed 20 outside steel mesh 17 to the interior wall body 6 surface of basic unit, screed 20 can make H shaped steel girder steel 2 and the interior wall body 6 surface of basic unit keep the parallel and level. If the pipeline 18 needs to be laid on the wall, the pipeline 18 needs to be hidden inside the wall for aesthetic purposes, namely: when pipeline 18 was laid along H shaped steel girder 2 and the interior wall body 6 wiring of basic unit, pipeline 18 penetrated inside the interior wall body 6 of basic unit along H shaped steel girder 2 flange side clearance, utilized the clearance between girder 2 flange and the interior wall body 6 of basic unit, laid pipeline 18 in steel mesh 17 inboard, the steel mesh 17 outside is leveled through screed-coat 20, has not only realized hiding of pipeline 18, also need not to bend at girder 2 and the interior wall body 6 junction of basic unit. Considering that the steel beam 2 is sometimes required to be connected with the external wall, as shown in fig. 4B-2, the web of the H-shaped steel beam 2 is connected with one side of the internal wall, and the connection can still be completed according to the structure given above, and the web of the H-shaped steel beam 2 is connected with the cavity outside the wall, so that the cast-in-place concrete layer 21 can be used for filling and forming the external facade wall, and the cast-in-place concrete mode can realize the required shape according to the design structure of the external facade wall.
For a steel frame-supporting structure system building, although the existing steel tube bundle combined shear wall can also achieve a good lateral stiffness resistance effect, the matching performance of the existing steel tube bundle combined shear wall with other connecting members is poor, the purpose that the supporting members are hidden in the wall cannot be achieved, and the arrangement of pipelines is not facilitated. Therefore, the invention adopts the structure of the steel beam column wall 3 on the aspect of improving the lateral force resistance of the building, not only can meet the design requirement of lateral force resistance, but also can be matched with other prefabricated components on connection to jointly realize the hiding effect, and can integrate the supporting function of the column and the beam and the function of the enclosure wall into a whole. The structure of the steel beam column wall 3 shown in fig. 6-1 to 6-3 in this embodiment includes edge columns 301 located at two sides, a plurality of support beams 302 welded between the edge columns 301 at two ends at equal intervals, and a plurality of bracing rods 303 welded between the edge columns 301 between adjacent support beams 302. The edge column 301 may be a steel pipe with a rectangular cross section, and if the edge column is a hollow steel pipe, whether concrete is poured inside the steel pipe or not can be selected according to the bearing capacity design requirement; or a steel column with the cross section being H-shaped steel or T-shaped steel can be selected; the edge posts 301 at the two ends can also be selected from different steel mixed combination, as shown in fig. 6-3, the free matching of the edge posts 301 at the two ends can 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 H-shaped steel or T-shaped steel, concrete or light filling materials are poured into cavities on two sides of a web plate of the steel section. The support beam 302 is made of H-shaped steel, the mounting position of the support beam 302 needs 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 larger than the width of the outer side connecting surface of the edge column 301. The bracing link 303 adopts a solid cross-section member, such as: angle steel, channel steel, strip steel plates and the like. The arrangement of the tension bars 303 may be diagonally staggered 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 section width of the supporting beam 302 in the embodiment is not larger than the width of the connecting surface of the edge column 301, and the section width of the bracing rod 303 is not larger than the width of the connecting surface of the edge column 301, so that after the combined connection, a certain space is left between the supporting assembly between the edge columns 301 and the outer surface of the edge column 301, the space is filled with the filling material 304, and an operation space is left for punching or grooving the pipe penetrating of the equipment junction box. After the above structures are assembled in a factory, steel nets 305 are respectively laid on two sides of the support beam 302, the steel nets 305 can be steel wire nets or steel plate nets, and finally, filling materials 304 are poured between the edge columns 301 at two ends, so that the support beam 302 and the brace rod 303 between the edge columns 301 at two ends are completely hidden by the filling materials 304, the filling materials 304 can be light filling materials or can be poured and filled with concrete, and the steel nets 305 play a role in preventing the filling materials from cracking. When the surfaces of the edge columns 301 at both ends do not need to be provided with the fireproof coatings, as shown in fig. 6-2, the total thickness of the filled fillers 304 is kept equal to the width of the connecting surface of the edge columns 301; if the surface of the edge post 301 needs to be provided with a fire-retardant coating, the total thickness of the filled filler 304 is greater than the width of the connecting surface of the edge post 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 post 301 and the thickness of the fire-retardant coating.
The steel beam column wall formed according to the structure can be flexibly matched and combined with the frame steel beams 2 to form different-shape nodes according to the plane size and the function arrangement requirements of a house building. The whole steel beam column wall body is designed in size, the whole length of the steel beam column wall body can be adjusted according to the actual stress, and a reliable lateral force resisting system is formed after combination by matching and selecting proper component specifications. When the pipeline is routed along the steel beam column wall 3, the pipeline is routed along the gap between the support beam 302 or the brace 303 to the surface of the packing layer 304.
In the building system disclosed in the embodiment, the column base node design adopts an exposed rigid-connection column base node structure, the size of the exposed end of the column base node is further reduced by improving the existing exposed rigid-connection column base node structure, and the design idea of the hidden function of the building system is met from another aspect. The exposed rigid-connection column base node structure is shown in figures 3A-1 to 3A-3, reinforcing plates 7 are arranged on four outer side surfaces of a column body 1, the reinforcing plates 7 are parallelly attached to the side surfaces of the column body 1 in a welding mode and fixed, in order to improve the connecting strength of the reinforcing plates 7 and the column body 1, a plurality of small round holes 13 are formed in the middle area of each reinforcing plate 7, and the positions of the small round holes 13 are connected with the side surfaces of the column body 1 in a plug welding mode. The provision of the reinforcing plate 7 increases the bending resistance load-bearing capacity of the column base joint. The embedded parts at the bottom of the column body 1 are arranged under the ground and are not exposed, after the embedded parts are arranged, the poured concrete jointly serves as a foundation to play a supporting role, and only the column body 1 and the reinforcing plate 7 are exposed, so that the size of the exposed end is obviously reduced. In order to realize that the bearing capacity of the part anchored into the ground is not less than that of the column body 1, a reinforcing design is carried out on an embedded part structure, namely: the embedded part comprises a bottom plate 8, anchoring steel bars 11 and anchoring section steel 10, wherein the bottom of the column body 1 and the bottom of the reinforcing plate 7 are welded on the top surface of the bottom plate 8 in a full penetration mode, and the anchoring section steel 10 is welded at four corners of the bottom surface of the bottom plate 8 and fixed in a girth welding mode; the bottom of anchor shaped steel 10 sets up anchor steel sheet 12, and 8 bottoms of bottom plate set up a plurality of anchor reinforcing bars 11, and anchor reinforcing bar 11 sets up a week along 8 four sides of bottom plate, perhaps only sets up all can in 8 middle parts of bottom plate, and anchor reinforcing bar 11 and bottom plate 8 adopt the plug weld of perforating to be connected. A pouring hole 15 is formed in the middle of the bottom plate 8, and a foundation is formed by pouring concrete 9 from the pouring hole 15 to the underground after the embedded part is arranged conveniently. Because adopt the hollow steel pipe of rectangle as cylinder 1 in this embodiment, the inside cavity of cylinder 1 needs the pouring concrete, for the construction of conveniently pouring, exhaust hole 14 has been seted up to cylinder 1 side. The design of the anchoring section steel 10 and the anchoring reinforcing steel bar 11 needs to consider the matching of the bearing capacity of the anchoring section steel and the bearing capacity of the steel column, the arrangement needs to be combined with the arrangement of the reinforcing steel bars in the foundation concrete, and the anchoring length is determined according to the specification. The peripheral size and the plate thickness of the bottom plate 8 can be determined by combining the structural requirements on the premise of meeting the standard requirements, and the specific size design also needs to be determined by combining the construction design standards.
