Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be further described below.

Example 1:

as shown in fig. 1, the utility model provides a steel bar truss floor deck with suspension ribs, which comprises a bottom plate 1 and a steel bar truss 2; the steel bar truss 2 is fixed on the bottom plate 1; the back of the bottom plate 1, i.e. the side facing away from the steel bar truss 2, is provided with at least two suspension ribs 3.

In this embodiment, the utility model discloses a steel bar truss 2 is traditional steel bar truss structure promptly, including web member reinforcing bar 22, last chord reinforcing bar 21 and last chord reinforcing bar 23, two last chord reinforcing bars 23 and a last chord reinforcing bar 21 build the triangle-shaped structure, realize fixed connection through welding web member reinforcing bar 22 between last chord reinforcing bar 21 and two last chord reinforcing bars 23 respectively.

As shown in fig. 2, the two suspension ribs of the present embodiment are the suspension rib 31 and the suspension rib 32, respectively, the two suspension ribs 31/32 are located at the side edge position of the bottom plate 1, and the two suspension ribs 31/32 are located at two opposite parallel sides of the bottom plate 1; the two suspension ribs 31/32 and the bottom plate 1 are integrally cast and molded, can be synchronously compounded with the truss molding equipment, can be produced at one time, and has the advantages of automatic production and high processing efficiency, so the cost is low, and a new thought and a new method are provided for the construction of the residential floor slab.

In this embodiment, among two hanging ribs 31/32, be equipped with the joint groove of another hanging rib 32 of pegging graft on a hanging rib 31, be convenient for on two bottom plates 1 that set up adjacently overlap joint between two hanging ribs 31/32 about, be convenient for adjust the required width of building carrier plate. As shown in fig. 4, the design of the overlapping edges also enhances the stiffness of the deck panels to form a "keel".

In the present embodiment, as shown in fig. 3, the suspension rib 31 of the two suspension ribs 31/32 is provided with a horizontal portion 311 for connecting to a ceiling; as shown in fig. 4, the suspended ceiling 4 is fixedly connected with the horizontal portion 311 of the suspension rib 31 through a self-tapping screw, so that the construction difficulty is reduced, and the integral structure of the floor deck is protected. Without the suspension ribs 31, the tapping screw directly hits the concrete slab, which is not only labor-consuming, but also damages the concrete slab and damages the structure.

In this embodiment, as shown in fig. 3 and 4, the hanging rib 31 connected to the suspended ceiling 4 further includes a section of vertical portion 312, and the vertical portion 312 is located between the horizontal portion 311 and the horizontal plane of the bottom plate 1, so that a gap is reserved between the suspended ceiling 4 and the bottom plate 1 after the fixing, and the conduit 5 of the lamp can pass through, thereby skillfully solving the problem that a large number of conduits in the floor slab are complicated to embed.

In addition, please see fig. 5, the utility model discloses a structure between hanging rib 31 and the hanging rib 32 is not only, can contain multiple overlap joint structure, as long as can realize that lapped overlap edge structure all can be used to hang rib 31 and the structure of hanging rib 32 between two adjacent bottom plates, but hang rib 31 must have one section horizontal segment 311 and vertical section 312, and horizontal segment 311 mainly is used for leveling after the furred ceiling is connected, the leveling of the furred ceiling of being convenient for, and the vertical section is convenient for arrange the spool between furred ceiling and floor deck.

Example 2:

as shown in fig. 6, the embodiment 2 is similar to the embodiment 1 in structure overall, except that the connection position between the suspension rib 3 and the bottom plate 1 is different, the suspension rib 3 is located at a position near the middle of the bottom plate 1, and the suspension rib 3 in this connection form can be integrally cast and molded with the bottom plate 1 as shown in fig. 6, and can also be fixed at any position of the bottom plate 1 by self-tapping nails and welding after the bottom plate is molded at a later stage, and after the pre-cast fixation, even after concrete is poured on a construction site, the connection between the ceiling and the suspension rib 3 can be realized, the integrity of the concrete is ensured, but the overlapping between the adjacent bottom plates 1 cannot be realized. Meanwhile, the suspension rib in embodiment 2 also has a horizontal section and a vertical section, as in embodiment 1, and the function is the same as in embodiment 1.

The above description is only for the preferred embodiment of the present invention, and does not limit the present invention. Any technical personnel who belongs to the technical field, in the scope that does not deviate from the technical scheme of the utility model, to the technical scheme and the technical content that the utility model discloses expose do the change such as the equivalent replacement of any form or modification, all belong to the content that does not break away from the technical scheme of the utility model, still belong to within the scope of protection of the utility model.
