Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to an early-strength steel truss floor deck. Background Technology

[0002] A truss constructed by connecting steel bars as the top chord, bottom chord, and web members using resistance spot welding is called a steel truss. A composite load-bearing slab formed by connecting a steel truss to a base slab using resistance spot welding is called a steel truss floor deck.

[0003] Patent CN202020596212.1 discloses a steel truss floor deck, comprising: a bottom formwork, a steel truss, and fasteners. The fasteners fix the steel truss to the bottom formwork. The bottom formwork is fixed with at least one handrail, which protrudes from the bottom formwork and has a handrail locking part for locking and fixing. When stacking the steel truss floor deck of this utility model, the handrails of each steel truss floor deck can be used for alignment. Fixing tools can be used to pass through the handrail locking parts of each steel truss floor deck to limit the position of each steel truss floor deck, making the steel truss floor deck of this utility model less prone to shaking during transportation. It can be easily handled with fixing tools, improving handling safety, and can make each steel truss floor deck aligned and placed flat, facilitating transportation.

[0004] When using steel truss floor decking, multiple steel truss floor deckings need to be connected. In the aforementioned patent, the handrails are fixed to both sides of the bottom formwork, which affects subsequent splicing and installation. Utility Model Content

[0031] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] like Figure 1-3 As shown, an early-strength reinforced concrete truss floor deck includes a bottom formwork 1, multiple sets of reinforcing bar assemblies, handles 3, and connecting components. The reinforcing bar assemblies are uniformly fixed on the bottom formwork. Each set of reinforcing bar assemblies includes an upper chord reinforcing bar 21, a lower chord reinforcing bar 22, and web reinforcing bars 23. There are two lower chord reinforcing bars 22, which are fixed to the bottom formwork. The upper chord reinforcing bar 21 is located directly above the middle of the two lower chord reinforcing bars. The web reinforcing bars 23 are fixed to the lower chord reinforcing bars and the upper chord reinforcing bars. The handles 3 are detachably connected to the bottom formwork through the connecting components. During construction, the reinforced concrete truss floor deck of this application is poured with early-strength cement. Early-strength cement is a type of cement with special functions. It can rapidly form high strength and harden early during the cement solidification process, hence the name "early-strength cement". Early-strength cement has many advantages over ordinary cement, such as high strength, short hardening time, good impermeability, and strong frost resistance.

[0033] Specifically, the connecting components include a connecting plate 41, a locking rod 42, a baffle 43, a tension spring 44, an insert plate 45, a roller 46, and a pull ring 47. The connecting plate 41 has an insertion groove 411, into which the bottom template can be inserted. Both ends of the handle are fixed to the connecting plate. The locking rod 52 can slide up and down relative to the connecting plate. Both the connecting plate and the bottom template have locking holes for the locking rod to slide into. The baffle 43 is fixed to the end of the locking rod. The tension spring 44 is sleeved on the locking rod, with one end fixed to the baffle and the other end fixed to the connecting plate. When it is necessary to move the steel truss floor slab, pull up the locking rod, align the insertion groove with the bottom template, and push the connecting plate so that the bottom template is inserted into the insertion groove. Then align the locking holes of the connecting plate and the bottom template. The spring pulls the locking rod into the locking hole, thus connecting the handle to the bottom formwork. This allows for easy handling of the steel truss floor slab. When splicing the steel truss floor slab, pulling the locking rod upwards and then pulling the handle outwards removes the handle and connecting plate from the bottom formwork, facilitating subsequent splicing and installation. The insert plate 45 is fixed to the connecting plate and has an inclined surface 451. When the bottom formwork is on the ground, the inclined surface can lift the bottom formwork, making it easier to clamp the connecting plate onto it. Rollers 46 are evenly distributed on the bottom surface of the connecting plate and are rotatably connected to it, reducing friction when pushing the connecting plate. The pull ring 47 is fixed to the fixing plate for easy pulling of the locking rod.

[0034] In other embodiments, a limiting plate 48 is fixed on the bottom template. The limiting plates are symmetrically located on both sides of the connecting plate. The limiting plates are provided with an arc-shaped guide surface 481 and a horizontal surface 482. The distance between the horizontal surfaces of the two limiting plates is the same as the length of the connecting plate. The position of the connecting plate can be guided by the arc-shaped guide surface. When the snap-fit ​​groove of the connecting plate is fully engaged with the bottom template, the two sides of the connecting plate will be attached to the horizontal surface. The locking holes of the bottom template and the connecting plate are aligned, which is convenient for installation.

[0035] In other embodiments, the gloves are provided with a rubber sleeve 49, and a plurality of anti-slip protrusions 491 are evenly provided on the outer wall of the rubber sleeve to improve comfort and anti-slip properties during handling.

[0036] In other embodiments, multiple positioning columns 24 are fixed on the lower chord steel bars, and the bottom template is provided with positioning holes into which the positioning columns are inserted to facilitate the fixing of the steel bar assembly.

[0037] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
