Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and in particular to a floor deck with staggered truss reinforcement. Background Technology

[0002] In the current engineering technology field, formwork-free steel truss floor slabs are a commonly used prefabricated floor slab technology. They are assembled from steel trusses and non-metallic formwork using specialized connectors, enabling formwork-free and minimally supported floor slabs. This technology is widely used in prefabricated buildings such as offices, schools, and residences. During the construction phase, the steel truss serves as the primary load-bearing component in formwork-free steel truss floor slabs, minimizing the need for additional support.

[0003] However, during construction, the water and electricity pipelines need to be interspersed within the truss web during pre-embedding. For commonly used steel truss floor slabs, the truss spacing is 200mm, making pipeline layout extremely difficult. The same applies to the transverse reinforcement perpendicular to the truss direction, significantly impacting construction efficiency. Furthermore, due to the triangular structure of the steel truss, the two bottom chords, and the structural requirements of the concrete structure, the truss spacing cannot be too large. Consequently, the amount of steel used exceeds twice the load-bearing requirements during the service phase, resulting in significant steel waste. However, for the load-bearing capacity during construction, the steel truss specifications are mainly controlled by concentrated loads, so the truss spacing can be appropriately increased, but the requirements for reinforcement structure must be addressed. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a truss steel bar staggered arrangement floor deck, which solves the problems of small steel bar truss spacing, large steel consumption, and inconvenience in arranging pipelines or transverse steel bars during construction in the existing non-removable bottom formwork steel truss floor deck.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A type of floor deck with staggered truss reinforcement includes a bottom formwork on which multiple parallel steel trusses are spaced apart. At least one longitudinal steel bar parallel to the steel truss is provided between two adjacent steel trusses, and there is a gap between the longitudinal steel bar and the steel truss, so that the steel trusses and the longitudinal steel bar are alternately distributed.

[0006] As an optimization, the steel truss includes one top chord and two bottom chords arranged in a triangular pattern, with web reinforcement between the top and bottom chords, and the bottom chords or web reinforcement are fixedly connected to the bottom formwork.

[0007] As an optimization, the longitudinal reinforcing bars are fixed to the bottom formwork by connectors.

[0008] As an optimization, the longitudinal reinforcement bars and the bottom chord reinforcement bars are on the same horizontal plane.

[0009] As an optimization, the longitudinal reinforcement is a single piece, and the spacing between the longitudinal reinforcement and the steel trusses on both sides is equal.

[0010] As an optimization, the longitudinal reinforcement bars are multiple bars, which are spaced apart.

[0011] Compared with the prior art, this application has the following advantages: This utility model, By setting longitudinal reinforcement bars between steel trusses, the steel trusses and longitudinal reinforcement bars are distributed alternately, thereby increasing the spacing between steel trusses. Furthermore, the amount of steel used can be optimized by flexibly setting the number and diameter of longitudinal reinforcement bars, which can significantly reduce steel consumption and improve economic efficiency. At the same time, the increased spacing of steel trusses can reduce the difficulty of pipeline and transverse reinforcement insertion during the construction phase, thereby improving construction efficiency.

[0012] Figure 1 This is a schematic diagram of the structure of this utility model; In the diagram, 1 is the bottom formwork, 2 is the steel truss, 3 is the longitudinal reinforcement, 4 is the top chord reinforcement, 5 is the bottom chord reinforcement, and 6 is the web reinforcement. Detailed Implementation

[0013] The present invention will now be described in further detail with reference to the accompanying drawings.

[0014] For specific implementation: see [link / reference] Figure 1 , An embodiment of a floor deck slab with staggered truss reinforcement includes a bottom formwork 1. In this embodiment, the bottom formwork 1 is a non-metallic formwork, such as calcium silicate board or OSB board, but metal plates can also be used. Multiple parallel steel trusses 2 are spaced apart on the bottom formwork 1. In this embodiment, the steel trusses 2 are triangular trusses, each including one upper chord 4 and two lower chord 5 arranged in a triangular pattern. Web reinforcement 6 is provided between the upper chord 4 and the lower chord 5. For non-metallic bottom formwork 1, the lower chord 5 is fixed to the bottom formwork 1 by connectors; for metallic bottom formwork 1, the lower chord 5 or the web reinforcement 6 is directly welded to the bottom formwork 1.

[0015] At least one longitudinal steel bar 3 parallel to the steel truss 2 is provided between two adjacent steel trusses 2. The longitudinal steel bar 3 is fixed to the bottom formwork 1 by a connector, and there is a gap between the longitudinal steel bar 3 and the steel truss 2, so that the steel truss 2 and the longitudinal steel bar 3 are alternately distributed. The connector is a conventional connector, and its specific structure will not be described in detail.

[0016] Specifically, the longitudinal reinforcement 3 is a single piece, and the spacing between the longitudinal reinforcement 3 and the steel truss 2 on both sides is equal. Alternatively, the longitudinal reinforcement 3 can be multiple pieces, with multiple longitudinal reinforcement 3 arranged at intervals. The specific choice between a single longitudinal reinforcement 3 and multiple pieces, as well as the spacing between multiple longitudinal reinforcement 3 pieces and the diameter of the longitudinal reinforcement 3, can be adjusted according to the stress characteristics and strength requirements of the floor deck and the overall reinforcement situation.

[0017] To facilitate the installation of pipelines or transverse reinforcing bars, the longitudinal reinforcing bars 3 and the lower chord reinforcing bars 5 are on the same horizontal plane.

[0018] In summary, this utility model increases the spacing between steel trusses by setting longitudinal steel bars between them, allowing the steel trusses and longitudinal steel bars to be distributed alternately. Furthermore, it allows for flexible optimization of steel bar usage by setting the number and diameter of longitudinal steel bars, which can significantly reduce steel consumption and improve economic efficiency. At the same time, the increased spacing between steel trusses reduces the difficulty of pipeline and transverse steel bar insertion during construction, thus improving construction efficiency.
