Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a formwork-free pile-slab structure that improves the quality of one-time casting. Background Technology

[0002] In construction engineering, the construction of pile-slab joints is a common operation. Traditionally, pile-slab joint construction typically uses wooden or steel formwork, which needs to be removed after concrete pouring. This not only consumes a significant amount of manpower, resources, and time, but also risks damaging the pile-slab joints due to improper formwork removal, affecting its quality and appearance. Furthermore, traditional construction methods present difficulties at the junction of the capping beam and the pile-slab joint during pouring, often resulting in problems such as insufficient concrete compaction, grout leakage, and cracks. Consequently, the strength and durability of the pile-slab joints fail to meet design requirements, leading to water seepage and reducing the overall stability and safety of the building structure. Therefore, a new construction method is urgently needed to solve these problems. Summary of the Invention

[0032] The component B2 has a hopper 14, a lifting ring 15 at the upper diagonal, a casting pipe 16 at the lower end, and an external thread 17 at the bottom end of the casting pipe 16;

[0033] The upper end of component C3 has an internal thread 18, which is connected and extended by the external thread 17 of component B2.

[0034] The component D4 is a cement fiberboard;

[0035] The component E5 has a rectangular cross-section, and the upper end and lower end of the component E5 have an upper slot 19 and a lower slot 20, respectively.

[0036] The component F6 has a square cross-section, and has a steel bar connection hole 21 on the back and a bendable folding member 22 on the front.

[0037] The component G7 has a connecting thread 23, which is connected and installed by the steel bar connecting hole 21 on the component F6.

[0038] The component G7 is installed on the concrete pile 9 by drilling holes or prefabrication; component G7 is connected and installed with component F6; component D4 is fixed in the slot of component F6 by self-tapping screws; the middle part of component A1 is installed with the fixing steel bar 10 of the concrete cap beam 8; component B2 is extended and installed with component C3; multiple components D4 are connected and installed with multiple components E5; the inter-pile slab concrete is poured from the hopper 14 at the upper end of component A1.

[0039] Furthermore, component F6 is a connecting clip, and component F6 is installed with component G7 through the steel bar connecting hole 21; component F6 is connected and installed with component D4 through the bendable folding member 22.

[0040] Furthermore, the length of component E5 is the same as the length of component D4; component D4 and component E5 are connected and installed through upper slot 19 and lower slot 20.

[0041] Furthermore, the component B2 is vertically connected to multiple components C3, which extends the hopper and the pipe to ensure the pouring of concrete between the piles.

[0042] During construction, first prepare the components A, B, C, D, E, F, and G required for the pouring of the pile-to-pile slab as required, and then proceed as follows:

[0043] Step 1: Prepare concrete that meets the design strength grade requirements, and conduct quality inspections on cement, aggregates, and admixtures to ensure that all indicators are qualified; at the same time, prepare cement fiberboard, check the size, flatness, and strength of the cement fiberboard, and ensure that the surface is flat and smooth, without deformation or damage.

[0044] Step 2: Clear the area between piles to ensure there are no debris or obstacles; accurately measure and mark the formwork installation position and the reinforcement layout position according to the design position of the pile slab.

[0045] Step 3: Debug the concrete mixing equipment, transport vehicles, and vibration equipment to ensure that the equipment is operating normally and meets the construction requirements;

[0046] Step 4: According to the design drawings, straighten, cut, and bend the reinforcing bars to ensure that the specifications, shape, and dimensions of the reinforcing bars meet the design requirements;

[0047] Step 5: Tie the reinforcing steel cage at the pile-slab location. The spacing, quantity, and anchorage length of the reinforcing steel bars shall be in accordance with the design requirements. Tie them firmly with wire and spot weld if necessary to ensure that the reinforcing steel bars do not shift during concrete pouring. Place spacers between the reinforcing steel bars and the formwork to ensure that the thickness of the concrete cover meets the requirements.

[0048] Step 6: Connect and install component G7 to concrete pile 9, and connect and install it with component F6. Use component E5 to connect and fix the cement fiberboard D4 that does not need to be removed to component F6, so as to ensure that the cement fiberboard D4 does not shift or deform during the concrete pouring process.

[0049] Step 7: Component B2 is extended and connected using C3, and the concrete for the pile slab is poured using component A1;

[0050] Step 8: Before pouring concrete, check the installation of reinforcing bars and the fixing of formwork again to ensure that they meet the requirements; at the same time, check the concrete mix proportions and slump indicators, and control the slump within an appropriate range to ensure the fluidity and workability of the concrete.

[0051] Step 9: During the pouring process, measure the pouring height of the concrete at any time to ensure that it reaches the design elevation; when approaching the design elevation, slow down the pouring speed and precisely control the pouring height to avoid over-pouring or under-pouring.

[0052] Step 10: After the concrete is poured, timely moisturizing and curing should be carried out. This can be done by covering it with plastic film or sprinkling water to keep the concrete surface moist.

[0053] Furthermore, in step nine, the concrete pouring adopts a layered pouring method, and the thickness of each layer should not be too large, generally controlled at around 300-500mm, so as to facilitate the compaction of the concrete and avoid the phenomenon of under-vibration or over-vibration.

[0054] This invention allows for one-time casting, eliminating the need for formwork removal, saving labor and time costs, avoiding damage during removal, and solving problems such as difficult construction at the junction of the cap beam and slab, poor casting quality, and easy water seepage in traditional processes. By optimizing the construction process, it effectively improves the quality of one-time casting of the pile-slab, enhances the stability and safety of the building structure, and has significant economic benefits and practical value.
