Referring to fig. 1, 2 and 3, the present application provides a hidden steel beam structure for steel structure houses, which includes a large span floor slab 3 and a hidden beam 1; the large-span floor slab 3 is arranged on a structural beam 9 of the steel structure house, and the structural beam 9 is supported below the large-span floor slab 3; the hidden beam 1 is erected and installed on the structural beam 9 or installed on the side of a structural column, the hidden beam is embedded in the large-span floor slab 3, and the hidden beam 1 and the structural beam 9 are not located at the same structural stress position of the large-span floor slab 3.
In the present embodiment, the structural beams 9 are explained as main beams which span and enclose a room space, divide the whole room area or each room area and are used as supports, and are used as main steel beams for floor slab support, which are generally installed between structural columns and adopt H-shaped steel; the structural columns are to be interpreted as structural uprights of the whole house for installing the beam structure of each floor, and the beam columns are unified conventional structures of prefabricated buildings or other buildings, which are prior art and are only explained herein, and should be understood by those skilled in the art.
In this embodiment, the structural beam 9 is a support beam of a floor slab, located below a large-span floor slab; the hidden beam has two installation modes, one mode is that the hidden beam is directly erected on the structural beam 9 and fixedly installed on the structural beam with the same elevation as the large-span floor slab 3; the second is that the installation is carried out on the structural column, but the installation position elevation is higher than the structural beam and can be embedded in the large-span floor slab.
According to the technical scheme, when the area of the integrated floor slab of the residential building is too large, the embedded hidden beam 1 is arranged in the floor slab with the large span, the hidden beam 1 is arranged in the floor slab with the large span, but the structural bearing force acts on the structural beam or the structural column, the large-span floor slab 3 is divided into mechanical small-span floor slabs due to the action of the hidden beam 1, the hidden beam 1 can be arranged in any place where the structural mechanics of the large-span floor slab 3 needs and cannot be exposed, and the convenience and the attractiveness of the large-space design of the residential building are greatly improved.
In view of structural strength, the hidden beam 1 is preferably H-shaped steel, a first through hole 112 is formed in a position, close to the upper flange 12, of a web 11 of the H-shaped steel, a shear rib 2 penetrates through the first through hole 112, and two ends of the shear rib 2 extend out of the upper flange 12 of the H-shaped steel. Short steel bars are welded at the bottom of the top flange 12 of the hidden beam 1 to form shear keys (similar to the function of studs of the top flange 12 of the steel beam in the composite floor slab) between the steel beam and post-poured concrete (namely, preferable pea-stone concrete), so that the steel beam and the post-poured concrete can form a composite beam bending resistance, the rigidity of the steel beam is greatly improved, the problem that the steel beam is not high in height but can meet the requirement of the stress of a living room span is solved, and the using amount of steel is saved.
Preferably, the anti-shear bar 2 is arranged in the first through hole 112, and the floor heating pipeline 113 can be arranged in the first through hole, because the first through hole 112 is structurally closest to the floor surface, the floor heating pipeline can be arranged conveniently.
Furthermore, the top surface of the shear rib 2 and the upper flange 12 of the H-shaped steel are welded together to further enhance the shear strength.
In order to facilitate the routing and pipeline layout in the fabricated structural floor slab, the web 11 of the H-beam is further provided with a second through hole 111, and the second through hole 111 and the first through hole 112 are not located on the same axis of the web 11. The second through-hole 111 serves to install the water and electricity line 114, and also to install the structural reinforcement for the floor slab casting. The number of the second through holes 111 may be plural, but it should be reasonably applicable to the separation of the intervals. The reason why the first and second through holes 112 and 111 cannot be coaxial is that if they are coaxial, the web weakening at the coaxial position will result in too much weakening of the steel beam in shear and bending resistance.
As a conventional construction of a floor slab structure, the structural ribs of a common floor slab are arranged in two layers, and the arrangement of the two layers of structural ribs is more efficient and concise in the embodiment, so that the large-span floor slab 3 at least comprises two layers of structural ribs and structural concrete; the first layer of structural ribs 31 are arranged on the inner side of the lower flange 13 of the hidden beam 1, the second layer of structural ribs 32 are arranged in the second through holes 111 in a penetrating mode, and the structural concrete is poured to wrap the first layer of structural ribs 31 and the second layer of structural ribs 32. Specifically, the first layer of structural ribs 31 are welded to the inner side of the lower flange 13 of the hidden beam 1 (i.e., the H-beam) during casting, and the second layer of structural ribs 32 are inserted into the second through holes 111; this completes the placement of the structural concrete, which is at an elevation no higher than that of the first bore 112. At this time, the pouring of the floor slab basically completes the pouring of the structure bearing area. The upper flange of the hidden beam is higher than the top surface of the structural concrete floor and enters the non-structural layer, and a hole can be reserved on the web side for a pipeline of the non-structural layer to facilitate the installation in a penetrating way.
Still further, the large-span floor slab 3 further comprises a heat insulation layer 4, a metal reflective foil layer, a metal wire mesh layer 5, a pea concrete layer 6, a ground leveling layer 7 and a bottom surface decoration layer 8 which are sequentially arranged on the structural concrete. Specifically, the heat-insulating layer 4 and the metal reflective foil layer are laid on the structural concrete, so that the floor heating in the first through hole 112 is prevented from dissipating heat downwards; then a layer of wire netting is welded to play a role in fixing the structure, and the wire netting and the hidden beam 1 are completed to form an integral heat dissipation prevention layer; and then the floor heating pipeline 113 and the water path pipeline are poured, and then the pea concrete (or other concrete, not limited by the above) is poured and filled in the first through holes 112 to complete the pouring of the whole functional area, and finally the leveling layer 7 is matched with the laying of the decorative layers such as the bottom plate, the ceramic tile and the like.
The assembly type structure has the advantages that the structure is attractive, and for this reason, the bottom surface of the hidden beam 1 is flush with the bottom surface of the large-span floor slab 3, so that the visual neat marking effect is formed, and the bottom of the floor slab is convenient to paint and decorate.
As described above, the number of the first through holes 112 and the second through holes 111 is plural, and the plural first through holes 112 and the plural second through holes 111 are opened in the web 11 along the longitudinal direction of the hidden beam 1. Preferably, the first through holes 112 and the second through holes 111 are arranged in a staggered manner, so that the overall stress of the structure is uniform and stable, and the situation that the bearing capacity is insufficient due to the fact that the steel consumption is reduced at a certain position because the first through holes 112 and the second through holes 111 are coaxial is avoided.
The beneficial effect of this embodiment does:
the hidden beam 1 is buried in the concrete floor, but the upper flange 12 is higher than the concrete floor, and the hidden beam 1 is penetrated through by floor heating and the like, so that the height of the hidden beam 1 actually reaches about 200 mm.
The shear resistant ribs 2 (short steel bars) are welded at the bottoms of the top flanges 12 of the hidden beams 1 to form shear resistant keys between the shear resistant ribs 2 and the pea gravel concrete (similar to the function of studs of the top flanges 12 of the steel beams in the composite floor slab), so that the hidden beams 1 and the pea gravel concrete can form a composite beam bending resistant structure, the rigidity of the steel beam is greatly improved, the problem that the height of the steel beam is not high, but the requirement on the span stress of a living room can be met is solved, and the steel consumption is saved.
At 11 trompils of girder steel web, solve the reinforcing bar arrangement in the floor, cable line buries the problem underground, and the thermal conversion of ground heating is higher because of the heat conductivity of girder steel.
The first perforation 112 near the top flange 12 of the hidden beam 1 is staggered with the second perforation 111 in the middle of the web 11, reducing the weakening of the cross section.
While the present invention has been described in detail and with reference to the embodiments thereof as illustrated in the accompanying drawings, it will be apparent to one skilled in the art that various changes and modifications can be made therein. Therefore, certain details of the embodiments are not to be interpreted as limiting, and the scope of the utility model is to be determined by the appended claims.
