Description

Technical Field

[0001] The present invention relates to the field of construction technology, and particularly to a partition wall for a batching plant silo of precast concrete. Background Art

[0002] A non-load-bearing interior wall is called a partition wall. The partition wall of the batching plant silo is a separating structure of the sand and gravel silo, which divides the silo into several separate storage silos to ensure the separate storage of concrete aggregates such as sand and stone, prevent the insufficient batching of the mixing system after the sand and gravel are mixed, and affect the strength of the mixture. The traditional partition walls of the material yard silos generally adopt forms such as grouted rubble masonry partition walls and brick-concrete partition walls, and there is also a relatively new structural form such as a wire mesh filled with crushed stones. However, the use of grouted rubble masonry partition walls and brick-concrete partition walls has large investment, wide land occupation, poor appearance, non-recyclability, and long curing time resulting in poor timeliness; although the wire mesh filled with crushed stones can be recycled, only some materials (such as steel columns) can be recycled, and the wire mesh is prone to rust and breakage, inducing the leakage of the filled crushed stones, causing the mixing of sand and gravel materials, and the repair is difficult.

[0003] The prior art discloses a reusable precast batching plant storage silo partition wall (application number: 201420721158.3). Among the multiple I-beam columns of the partition wall, bolt holes are preset on every other I-beam, and bolt holes are also preset on the inverted U-shaped steel plate according to the positions of the bolt holes preset on the I-beams. The inverted U-shaped steel plate and the I-beams are fixed by tightening bolts; bolt holes are preset on the corrugated steel plate according to the positions of the bolt holes preset on the I-beams, and the corrugated steel plate and the I-beam columns are fixed by tightening bolts.

[0004] The prior art also discloses a precast corrugated steel plate silo partition wall (application number: 201820805542.X), which includes a first combined steel plate and a second combined steel plate. A first connecting block is fixedly connected to the right side of the first combined steel plate, a second connecting block is fixedly connected to the left side of the second combined steel plate, a clamping block is fixedly connected to the left side of the second connecting block, a clamping groove matching with the clamping block is formed at the position corresponding to the clamping block on the right side of the first connecting block, and fixing screw holes are formed on the front surfaces of the first connecting block and the second connecting block.

[0005] In the above technical solutions, the method of using a corrugated steel plate fixed on a pre-embedded steel column for the lightweight partition wall, although it improves many disadvantages of the concrete wall and the block-concrete wall, the connections mostly adopt connection methods such as self-tapping screws and bolts. Using this connection method for the roof and the building exterior wall is firm and durable, but for the partition wall, there are disadvantages such as cumbersome installation, troublesome disassembly, excessive loss, and non-reusability; while another precast corrugated steel plate silo partition wall is detachable and does not cause material waste, but its structure is relatively complex, the precision requirements for prefabrication and processing are high, and the installation method is not convenient and fast enough. Summary of the Invention

[0006] To address the deficiencies of the above technical solutions, the present invention provides a prefabricated concrete mixing plant silo partition wall and its installation method. The structure of this partition wall is simple, with few components, stable and reliable, and is more economical, green and environmentally friendly.

[0007] Another object of the present invention is to provide a prefabricated concrete mixing plant silo partition wall and its installation method, which can reduce the construction difficulty of the silo partition wall, the assembly method is fast and convenient, improves the construction efficiency of the partition wall, and the components can be reused repeatedly, with the characteristics of high efficiency, safety, easy operation, low cost, green and environmentally friendly.

[0035] In this embodiment, a plurality of bolt holes are symmetrically arranged on the left and right sides of the steel column 1. The Z-shaped hanging parts 3 are detachably arranged on the steel column 1 through the cooperation of the bolt holes and bolts.

[0036] In this embodiment, the card slot openings 21 are arranged at the head and tail wave troughs on the left and right sides of the profiled steel sheet 2, and the length of the card slot openings 21 is half of the length of the Z-shaped hanging member 3.

The length of the card slot openings 21 is set to be half of the length of the Z-shaped hanging member 3, and two adjacent profiled steel sheets 2 can be exactly and tightly connected together through the Z-shaped hanging member 3.

[0037] In this embodiment, the Z-shaped hanging member 3 includes a connecting portion 31, a clamping portion 32 and a limiting portion 33. The connecting portion 31, the clamping portion 32 and the limiting portion 33 are connected in sequence to form a Z-shaped structure, and the connection position between the clamping portion 32 and the limiting portion 33 is adapted to the waveform of the profiled steel sheet 2. A fixing hole 34 is arranged on the connecting portion 31, and the Z-shaped hanging member 3 is fastened to the steel column 1 through the cooperation of bolts and the fixing hole 34 and the bolt hole.

[0038] Furthermore, a card interface 22 is arranged in the middle of the profiled steel sheet 2. The card interface 22 corresponds to the position of the card slot opening 21, and the card interface 22 is adapted to the Z-shaped hanging member 3. A card interface 22 is also arranged in the middle of the profiled steel sheet 2, which increases the connection between a single profiled steel sheet 2 and multiple Z-shaped hanging members 3 and improves the connection stability.

[0039] In this embodiment, the profiled steel sheet 2 includes a high-zinc layer galvanized floor bearing steel sheet with a plate thickness of 1.5 mm and a wave height of 75 mm. The profiled steel sheet adopts a high-zinc layer galvanized floor bearing steel sheet, which has strong anti-impact, bending, compression and anti-overturning performance. As a lateral stiffness support, it has high quality, is firm and durable, has strong anti-impact, anti-overturning and load-bearing capacity, and has a high safety factor.

[0041] An installation method for a prefabricated concrete mixing plant bunker partition wall, characterized by comprising the following steps:

[0042] S1: Level the site, clean the sundries and accumulated water on the ground, and do a good job in temporary drainage;

[0043] S2: Carry out foundation lofting, mark out the position and elevation of the partition wall foundation, and sprinkle the foundation plane shape with lime powder;

[0044] S3: Excavate the foundation, pre-embed the anchor bolts and cast the concrete foundation;

[0045] S4: Fix the steel column on the pre-embedded anchor bolts, and level the elevation of the steel column bottom plate through the double nuts of the anchor bolts, with a height difference of ±5 mm;

[0046] S5: Install the Z-shaped hanging members on the left and right sides of the steel column through bolts;

[0047] S6: Suspend and snap-connect the profiled steel sheet to the Z-shaped hanger. After covering the inverted U-shaped steel sheet, tighten and fix it to the steel column with bolts.

[0048] Furthermore, in step S3, the length of the embedded anchor bolt is 60 cm. Then cast-in-place concrete is carried out. After the concrete strength reaches the standard, ensure that the anchor bolt exposes ≥12 cm above the foundation surface.

[0049] Single profiled steel sheets are fabricated according to the specified length. Cut slots at the troughs at both ends of the profiled steel sheet. The Z-shaped hangers are rolled according to the profiled steel sheet model. The Z-shaped hangers and the profiled steel sheet fit well in the wave height part. During installation, fix the Z-shaped hangers to the steel column with bolts, push the slot of the profiled steel sheet to the position of the Z-shaped hanger and let it down. The single profiled steel sheet automatically snaps into the position of the Z-shaped hanger under its own weight.

[0050] There are no holes on the surface of the profiled steel sheet except at the slot and / or snap-connection positions. Disassembly does not cause loss, making it green and environmentally friendly as a wall panel. The profiled steel sheet adopts a snap-connection method. The disassembly and assembly only need to be pushed and snapped to complete the operation, saving 80% of the time compared with methods such as bolts and self-tapping screws. The thickness of the Z-shaped hanger is 4 mm, with 4 or 6 single-plate fasteners. The overall performance of a single sheet is good, and the overall wall panel is safer.

[0051] The anchor bolts for the assembly of the steel column and the foundation are connected by bolts, and the disassembly and assembly loss of the steel column is zero. The profiled steel sheet and the steel column are snap-connected through the Z-shaped hanger, and the disassembly and assembly loss of the wall and its accessories is zero. The overall disassembly and assembly do not generate construction waste, making the wall more green and environmentally friendly. Due to the frequent transfer of engineering construction projects, its supporting mixing station also transfers accordingly. The advantages of this bunker partition wall are particularly obvious for such construction projects.

[0052] This partition wall is completely prefabricated, with simple fabrication and installation. When the mixing station is transferred, the foundation construction can be completed in advance without the need for the arrival of partition wall components; the profiled steel sheet and the steel column are snap-connected, and the installation is completed by simply pushing and snapping, which is time-saving and labor-saving compared with bolt connection, shortening the installation cycle and greatly accelerating the commissioning time of the material yard. This partition wall is more prominent in improving the construction efficiency of the partition wall, reducing the construction difficulty, and being green and environmentally friendly.

[0053] The advantages of this application are that the structure of this partition wall is simple, with few components, stable and reliable. The profiled steel sheet has good corrosion resistance, is more economical, and can reduce the construction difficulty of the bunker partition wall. The assembly method is fast and convenient, improving the construction efficiency of the partition wall; the components can be reused repeatedly, with the characteristics of high efficiency, safety, easy operation, low cost, and green environmental protection.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
