Description

Technical Field

[0001] The utility model belongs to the technical field of building materials, and in particular relates to a reinforced concrete composite slab. Background Art

[0002] Composite slabs are a better structural form that combines prefabricated and cast-in-place concrete. They can be widely used in various housing construction projects such as hotels, office buildings, schools, residences, hospitals, warehouses, parking lots, multi-storey industrial plants, etc.

[0003] Since traditional prefabricated composite slabs are mostly two-way slabs, they are generally reinforced on all four sides and the reinforcement is long and complex in shape, resulting in high production costs and low efficiency in prefabrication factories. Steel bar collisions are very common during the construction and installation process, posing a safety hazard. In addition, existing prefabricated concrete composite slabs require additional reinforcement structures to achieve a bearing capacity equivalent to that of cast-in-place slabs, which not only increases the cost but also increases the difficulty of construction. Utility Model Content

[0004] The utility model aims to provide a reinforced concrete composite slab to solve the technical problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: a reinforced concrete composite slab, comprising a precast panel body and a steel truss arranged inside the precast panel body, wherein a long side wall of the precast panel body is provided with a plurality of equally spaced connecting sleeves, and the other long side wall is provided with plug blocks distributed one-to-one with the connecting sleeves, and two adjacent precast panel bodies are connected by a plurality of equally spaced T-shaped pieces, and the steel truss comprises a plurality of equally spaced transverse reinforcements, and the upper surface of the transverse reinforcement is provided with at least three equally spaced lower longitudinal reinforcements along its length direction, and an upper longitudinal reinforcement parallel to the lower longitudinal reinforcement is provided above each of the lower longitudinal reinforcements, and the lower longitudinal reinforcements are fixedly connected to the upper longitudinal reinforcements by a plurality of V-shaped reinforcements connected end to end in sequence.

[0006] Preferably, a slot is provided at the end of the connecting sleeve, and the size of the insert block matches the size of the slot.

[0007] Preferably, a plurality of grooves distributed at equal intervals are provided at the bottom of both long sides of the prefabricated plate body, and there is a groove between every two connecting sleeves.

[0008] Preferably, the T-shaped member includes a vertical plate, and horizontal plates with sizes matching the groove are arranged on both sides of the bottom of the vertical plate. The vertical plate is located between two connecting sleeves, and the top of the vertical plate extends to the top of the prefabricated plate body. The side wall of the vertical plate is provided with a plurality of equally spaced sockets, each of which is inserted with a reinforcing rib, and the bottom of the reinforcing rib is in contact with the upper surface of the prefabricated plate body.

[0009] Preferably, the transverse reinforcement is distributed in parallel with the short side of the prefabricated board, the lower longitudinal reinforcement is distributed in parallel with the long side of the prefabricated board, and the upper longitudinal reinforcement is located above the prefabricated board.

[0010] Preferably, the prefabricated plate body is provided with four hanging rings distributed in a rectangular shape, and the bottom of each hanging ring extends to the inner cavity of the prefabricated plate body and is provided with a transverse reinforcement rib, and the upper surface of the reinforcement rib is in contact with the bottom of the transverse rib.

[0011] The reinforced concrete composite slab of the utility model has the following advantages:

[0012] 1. The utility model can make two adjacent prefabricated panels closely butted against each other through the cooperation between the insert block and the slot, and prevent long steel bars from extending around the prefabricated panels, which not only reduces the cost but also improves safety. Moreover, through the arrangement of the T-shaped piece, the two prefabricated panels can form a stable overall structure with the T-shaped piece, which greatly improves the overall strength of the composite panel. Moreover, the T-shaped piece firmly supports the bottom of the two prefabricated panels, and has good stability.

[0013] 2. The upper longitudinal reinforcement is located above the precast panel, so that when the concrete slab is poured above the precast panel, the steel truss will firmly connect the precast panel and the concrete slab to form an integral structure, further improving the strength of the entire structure. Multiple V-shaped reinforcements and the lower longitudinal reinforcements and upper longitudinal reinforcements form multiple stable triangular structures, thereby greatly improving the overall strength of the composite panel.

[0014] 3. By setting the reinforcing bars, the two sides of the bottom of the lifting ring will be connected to the transverse bars at the bottom. When the lifting ring is lifted, an upward force will be generated on the transverse bars, thereby effectively preventing the prefabricated board from loosening when lifting the prefabricated board.
