Abstract
Description
Technical Field
[0001] This invention relates to the field of precast concrete component storage, specifically a convenient and high-precision precast composite floor slab component stacking support structure. Background Technology
[0002] Compared to the traditional 100% cast-in-place concrete construction process, which suffers from high labor intensity, poor construction conditions, long construction cycles, and severe environmental pollution, precast assembly construction technology allows for the prefabrication of structural components in factories, resulting in a high degree of mechanization. This ensures construction quality while reducing on-site formwork usage, lowering construction costs, and shortening the construction cycle. Precast composite floor slabs are a commonly used and quick-assembly method in prefabricated buildings. This component consists of two parts: the upper structure is cast in-situ with concrete, while the lower structure is precast in the factory and assembled on-site. Structurally, the lower structure of the precast composite slab is a thin-layered component with dimensions much larger than its thickness, thus its vertical deformation resistance is relatively limited.
[0003] In actual production, to ensure construction progress and improve the turnover rate of factory formwork, precast concrete plants typically demold, hoist, and stack precast components at the minimum strength limit required by specifications. At this point, the concrete has not yet reached the final design strength requirement, making the hoisting and stacking operations of finished components particularly sensitive and important. Currently, independent wooden supports are a common method during component stacking and storage. Although this support method is simple, quick, and inexpensive, its placement, location, and selection of wooden supports are greatly affected by human factors. Especially for composite floor slabs with large self-weight and thinness, the lack of stacking support structures or inaccurate placement can lead to deflection or central arching deformation of the components under their own weight, causing cracks in the concrete composite slab. This seriously affects the finished product quality and appearance of the precast components and is also detrimental to ensuring the yield rate and controlling operating costs of the precast component plant. Summary of the Invention
[0004] The present invention aims to solve the above problems, thereby providing a convenient high-precision prefabricated composite floor slab component stacking support structure that is simple to operate, fast, highly accurate, and can be flexibly combined.
[0005] The technical solution adopted by the present invention to solve the aforementioned problem is as follows:
[0006] A convenient, high-precision precast composite floor slab component stacking support structure includes a first fixed link, a second fixed link below the first fixed link, a first fixing hole opposite to the middle of the first and second fixed links, movable links on both sides of the bottom of the first fixed link and both sides of the top of the second fixed link respectively, a second fixing hole opposite to the first fixed link and the second fixed link, and a third fixing hole at the outer end of the movable link, with floor slab pads movably passing through the first, second, and third fixing holes respectively.
[0007] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art:
[0008] The position of the movable connecting rod is adjusted in advance according to the size of the precast composite floor slab. The floor slab pad in the first fixing hole supports the middle of the concrete composite slab, and the floor slab pad in the third fixing hole supports the edge of the concrete composite slab. The concrete composite slab is supported at multiple points through the floor slab pads. The working principle is simple, the installation process is simple and quick, and the overall weight is relatively light, which allows workers to quickly get started and operate by one person. The entire support structure is a reusable structure that can be reused multiple times. The horizontal opening and closing angle of the fixing connecting rod can be adjusted at multiple angles, which can achieve precise positioning and support for precast composite slab components of different sizes. All components of the support structure can be disassembled, which is convenient for daily use and storage and organization during transportation, saving space.
[0009] As a preferred embodiment, a further technical solution of the present invention is:
[0010] The second fixing hole is a long strip hole.
[0011] The first and second fixed links have scales on their sides, and the movable link has an indicator arrow on its side that corresponds to the scales.
[0012] The floor slab padding includes a sleeve with a movable through-hole fixing hole, a column inserted in the sleeve, a channel steel at the bottom of the sleeve and the top of the column, and wooden pads on opposite sides of the channel steel.
[0013] A pad is provided on the sleeve between the third fixing hole of the movable link connected to the second fixed link and its bottom channel steel.
[0014] A scale is provided on the bottom surface of the channel steel above the first fixing hole, and positioning arrows opposite to the scale are respectively provided on the top center of the first fixing rod and the second fixing rod, located on both sides of the first fixing hole.

[0026] The first fixed link 1 and the second fixed link 2 are provided with scales on their sides, and the movable link 3 is provided with an indicator arrow on its side that is opposite to the scales. The lengths of the first fixed link 1, the second fixed link 2 and the movable link 3 are determined, and the extension length of the movable link 3 is controlled by the indicator arrows and the scales.
[0027] The floor slab pad 4 includes a sleeve 41 with movable through fixing holes. The fixing holes include a first fixing hole 5, a second fixing hole 6, and a third fixing hole 7. The bottom end of the sleeve 41 is located below the fixing holes. A column 42 is inserted into the sleeve 41. The top end of the column 42 is located above the fixing holes. Channel steel 43 is provided at the bottom end of the sleeve 41 and the top end of the column 42, respectively. Wooden pads 44 are provided on the opposite surfaces of the channel steel 43. The wooden pads 44 support the precast composite floor slabs at the top and bottom.
[0028] A pad 8 is provided on the sleeve 41 between the third fixing hole 7 of the movable link 3 connected to the second fixed link 2 and its bottom channel steel 43. The pad 8 is installed according to the height difference between the movable link 3 and the bottom channel steel 43.
