Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to a curved multi-rib sandwich wall panel and a manufacturing method thereof, a silo and a construction method thereof. Background Art

[0002] A silo is a vertical cylindrical structure or container used to store bulk materials (such as grain, feed, cement, coal powder, wood chips, etc.). Its height is much larger than its diameter, which makes full use of the vertical space and saves floor space.

[0003] At the same time, new or abandoned silos can be used as the base of the observation tower by adding external stairs and entrances and cutting viewing windows inside.

[0004] However, there are two main methods for the construction of existing silos: steel silos and concrete silos. However, concrete silos are more popular in terms of popularity. At the same time, bird watching towers are also mainly made of concrete. In the existing concrete silo pouring process, slipform construction is more commonly used. The slipform construction template system slowly and continuously slides upward along the cylinder wall while continuously pouring concrete. It is highly efficient and can form an integral seamless cylinder wall with high structural strength and smooth surface. Although slipform construction has good advantages, it also has the following disadvantages: Slipform construction requires extremely high continuity. Throughout the construction process, multiple departments must be highly coordinated to ensure uninterrupted operations before completion. If there is a delay in any link or due to weather conditions, cold joints can easily occur, which are difficult to handle and the quality of the subsequent work cannot be guaranteed. The technical requirements are high, and real-time monitoring and timely correction are required throughout the construction process. Improper operation can easily lead to the final result not meeting the design requirements and may even cause safety accidents.

[0005] The cost is high. First, the quality of the concrete must be strictly controlled within a very narrow range. Therefore, the concrete has high requirements. Secondly, it usually needs to be specially designed and manufactured according to the project. It is non-standard equipment. Therefore, the cost is high. Therefore, there is another method, which is jump formwork construction. The casting is carried out in sections. After each section is cast, the formwork is lifted to the next section. Although it solves the problem of high continuity requirements and high costs of slipform construction, its speed is slower than that of slipform construction. At the same time, the horizontal joints in the structure need to be properly handled. If not handled properly, cold joints are easily formed, which seriously affect the integrity of the subsequent structure. At the same time, it has many processes and cumbersome disassembly and assembly, which indirectly leads to its high cost, but it is lower than the cost of slipform construction.

[0006] Therefore, both slip formwork and jump formwork have their own advantages and disadvantages for silo construction. Therefore, in the existing construction process, jump formwork or slip formwork is selected based on factors such as project schedule, cost, structural characteristics, quality requirements, resource conditions, etc., so the experience and professional ability of the personnel must be strong. Therefore, there is an urgent need for a silo construction structure and construction method that is low in cost, structurally safe, and does not rely on the strong professional ability of the staff. Summary of the Invention

[0007] In view of this, in order to solve the problems in the prior art that the silo construction method is difficult to select and overly dependent on professionals, and the cost is relatively high, the present invention provides a curved ribbed sandwich wall panel and manufacturing method, a silo and construction method.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions: A curved multi-rib sandwich wall panel comprises a curved wall panel body, a plurality of curved filling blocks are arranged inside the wall panel body, left and right connecting parts are arranged at the left and right ends of the wall panel body, and upper and lower connecting parts are arranged at the upper end of the wall panel body.

[0009] As a further improvement of the above technical solution: As an optimization solution of the above technical solution, the arc-shaped filling block is any one of an arc-shaped solid filling block, a foam-filled arc-shaped sandwich filling block or an arc-shaped foam-filled T-shaped building block filling block.

[0010] As an optimized solution of the above technical solution, the upper and lower connecting parts include a sleeve grouting connection channel located at the lower end of the wall panel body and a connecting grouting groove at the upper end of the wall panel body. The sleeve grouting connection channel is hook-shaped, and one port of the sleeve grouting connection channel is located at the lower end of the wall panel body, and the other port is located at the outer facade of the wall panel body. The lower port of the sleeve grouting connection channel corresponds to the upper end of the connecting grouting groove.

[0011] As an optimization solution of the above technical solution, the left and right connecting components are concave connecting grooves located on the left and right end surfaces of the wall panel body.

[0012] As an optimization solution of the above technical solution, the left and right connecting components are threaded connection boxes embedded on the left and right facades of the wall panel body.

[0013] As an optimized solution of the above technical solution, the wall panel body includes an arc-shaped inner panel located on the inner facade, an arc-shaped outer panel located on the outer facade, and a plurality of cross-arranged cast longitudinal ribs and cast transverse ribs located between the arc-shaped inner panel and the arc-shaped outer panel, and the arc-shaped filling block is located in the space formed by the cast longitudinal ribs and the cast transverse ribs.

[0014] The present invention also provides a method for manufacturing a curved multi-rib sandwich wall panel, comprising the following steps: Step 11. Build the arc-shaped inner and outer molds; Step 12: Adjust the distance between the inner mold and the outer mold so that they are coaxially distributed. Step 13: Build side forms on both sides of the inner and outer forms so that the spatial shape they form is the same as the shape of the wall panel itself and the size meets the construction requirements; Step 14: Pour the bottom layer of the wall panel into the prepared casting mold; Step 15: After the bottom layer of the wall panel solidifies, place several arc-shaped filling blocks at the corresponding positions on the upper end of the bottom layer and pour again until the concrete is higher than the designed distance from the upper surface of the arc-shaped filling blocks. Then stop pouring. Step 16: Repeat Step 15 until the entire wall panel is poured; Step 17. When the entire wall panel body solidifies, remove the inner mold, outer mold and side mold to complete the processing of the wall panel body.

[0015] The present invention also provides a silo manufactured using curved dense-ribbed sandwich wall panels, including a silo assembly layer assembled in a circular shape by a plurality of curved dense-ribbed sandwich wall panels, wherein two adjacent curved dense-ribbed sandwich wall panels are fixedly connected by left and right connecting components, and a plurality of the silo assembly layers are stacked in sequence from bottom to top and fixedly connected by upper and lower connecting components to form a silo.

[0016] As a further improvement of the above technical solution: As an optimization solution of the above technical solution, the upper end of the silo assembly layer is formed by connecting the upper ends of multiple arc-shaped dense-rib sandwich wall panels to grouting grooves to form a circular grouting groove, and a circular steel pipe is arranged in the circular grouting groove. The adjacent silo assembly layers are fixedly connected to the post-grouting ring beam between the above-mentioned circular grouting grooves through a sleeve grouting connection channel.

[0017] The present invention also provides a method for constructing a silo, comprising the following steps: Step 21: Mark the construction site and plan the location of each curved ribbed sandwich wall panel; Step 22: Use a crane to hoist the curved ribbed sandwich wall panel to the pre-planned location and support it with formwork; Step 23: Use the left and right connecting parts to fix and connect the adjacent curved multi-rib sandwich wall panels. After all the connections are completed, the first silo assembly layer is obtained. Step 24: Build the formwork to form the silo assembly position on the upper level; Step 25: Use a crane to hoist the curved dense-rib sandwich wall panels onto the curved dense-rib sandwich wall panels of the next layer, and hoist them one by one to form the upper silo assembly layer; Step 26: Use the left and right connecting parts to fix and connect the adjacent curved multi-rib sandwich wall panels. After all the connections are completed, the upper silo assembly layer is obtained. Step 27: Use upper and lower connecting parts to securely connect the upper and lower silo assembly layers. Step 28. Repeat Step 24 to Step 27 until the entire silo is assembled and demolded.

[0018] Compared with the existing technology, the beneficial effects of the present invention are: The arc-shaped dense-rib sandwich wall panel provided by the present invention has an arc-shaped design for both the internal filling blocks and the external wall panels, which perfectly adapts to the construction requirements of the cylindrical structure of the silo, and is also suitable for the construction requirements of other similar arc-shaped or cylindrical buildings. At the same time, because the internal filling blocks are also arc-shaped, they fit the wall panel body, ensuring the quality of the entire wall panel, so that the thermal insulation performance of each position is almost the same. At the same time, the design of the filling blocks greatly reduces the amount of concrete used while ensuring the structural strength, and at the same time reduces the dead weight of the wall panel.

[0019] The filling blocks of the present invention can be of different types, and suitable internal filling blocks can be selected according to actual needs, mainly according to different insulation, sound insulation or load-bearing requirements of the silo usage scenario.

[0020] The curved multi-rib sandwich wall panel provided by the present invention is cast in the later stage through the upper and lower connecting components and the left and right connecting components, thereby ensuring the filling of the overall structural wall and the gap during the assembly process, while reducing the construction difficulty during the assembly process.

[0021] The present invention also provides a method for processing curved wall panels. The main reason is that the wall panels of the present invention are curved in shape. If conventional flat-laying formwork is used for casting, the filling blocks may slide during the casting process and the curved shape of the facade may be difficult to meet the standards. Therefore, the layered casting scheme provided by the present invention is adopted. The entire process is simple to operate, and the position of the filling blocks can be effectively fixed, ensuring that the filling blocks are evenly distributed in the wall panel body, thereby ensuring the quality of the wall panel body after processing.

[0022] The present invention also provides a silo and a construction method thereof; ① First, it solves the stringent requirements of slipform construction for continuous operation and the segmented joint problem of jump form construction. The prefabricated wall panels can be mass-produced in advance in the factory, and the construction site only requires hoisting and splicing, so they are not affected by the environment. At the same time, the entire process has fewer casting parts, simple procedures (mainly hoisting), and faster construction speed. ② Secondly, the cost has been greatly reduced, mainly because the wall panels are processed in the factory as a whole, avoiding the waste of on-site concrete. The design of the filling blocks inside the wall panels also greatly saves concrete. The entire process mainly uses hoisting equipment, which has low equipment costs and lower requirements for workers, thus reducing labor costs. Therefore, the overall cost has been greatly reduced. ③ The structural integrity and quality have been greatly enhanced. On the same floor, through the left and right connection components, if the concave connection groove is used, the two adjacent wall panels form a casting groove. The post-cast structural columns make the wall panels on the same floor tightly connected, ensuring the integrity and stability of the same floor. If a threaded connection box is used, it is connected by bolts and nuts, and the gap is filled with concrete, which also ensures the connectivity between the wall panels. Between the upper and lower levels, a sleeve grouting connection channel is used in conjunction with a circular grouting trough composed of multiple connecting grouting grooves. At the same time, a circular steel pipe is placed in the circular grouting trough, and grouting is performed through the sleeve grouting connection channel to form a ring beam, ensuring that the upper and lower wall panels have a stronger integrity and reliable force transmission. Therefore, through the action of the upper and lower connecting components and the left and right connecting components, the constructed silo has a strong integrity and stable quality; ④ The construction difficulty of silo construction is reduced. The entire process is constructed by hoisting, which reduces the technical requirements for construction workers. Therefore, the construction progress has been greatly enhanced (no longer relying on professional talents) and the construction difficulty has been greatly reduced. At the same time, high-altitude continuous pouring and the construction of complex formwork have been reduced, and construction safety has been greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] In the description of the present invention, unless otherwise specified, "plurality" means two or more; terms such as "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," and "tail" indicate positions or relationships based on those shown in the accompanying drawings. These terms are intended solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limiting the present invention. Furthermore, terms such as "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] This technical solution is mainly used for the construction of silos. At the same time, the silo in this technical solution is a prefabricated building, which is made of wall panels. Therefore, this technical solution mainly includes two parts, mainly the wall panel main part and the silo part; Example 1 Example 1 mainly explains the relevant structure of the main body of the wall panel, which is as follows: As attached Figure 1 As shown, the outer structure of the wall panel body is mainly arc-shaped, mainly because the structure of the silo is cylindrical. Therefore, multiple arc-shaped wall panel bodies can be spliced ​​together to form a circle. Therefore, the arc angle of the wall panel body can be freely adjusted according to needs. The angle of the wall panel body in this technical solution is 36 degrees, so 10 wall panel bodies can just form a whole circle.

[0029] As attached Figure 2 With attached Figure 3 As shown, the structure of the wall panel body mainly includes the curved inner plate 2 of the inner facade and the curved outer plate 3 of the outer facade. According to the design standard, the curved inner plate 2 and the curved outer plate 3 should be coaxially distributed, so that the assembled silo or column can meet the circular requirements of the assembly. Between the curved inner panel 2 and the curved outer panel 3, there are multiple cast longitudinal ribs 5 and cast transverse ribs 6 that are cross-arranged. In the gaps formed between the cast longitudinal ribs 5 and the cast transverse ribs 6, there are arc-shaped filling blocks 4. The arc-shaped filling blocks 4 should also be coaxially distributed with the curved inner panel 2 or the curved outer panel 3. Therefore, under the premise of ensuring the overall strength of the wall panel, the insertion of several arc-shaped filling blocks 4 greatly reduces the overall concrete poured. At the same time, there are various forms of filling blocks. This design mainly includes the following three types of filling blocks: ①Solid filling block, as shown in the attached Figure 2 With attached Figure 3 As shown in the figure, compared with other filling blocks, solid filling blocks are the best in terms of load-bearing capacity. Solid filling blocks mainly include straw fiber ceramsite foamed concrete filling blocks or straw fiber soil filling blocks. ②Sandwich filling block, as shown in the attached Figure 5 As shown, compared with solid filling blocks, it is lighter and has good thermal insulation and sound insulation effects. It is mainly composed of straw fiber ceramsite concrete sandwich filling blocks, and the sandwich part is filled with foam; ③Tianzi-shaped block filling blocks, as shown in the attached Figure 6 As shown, its effect is the same as that of the sandwich filling block. Its structure is that a field-shaped groove is set on the facade, and the groove is filled with foam.

[0030] Since the wall panel body is the main splicing component for the assembled silo, there should be connecting parts on the left and right sides and the upper and lower sides of the wall panel body 1. The specific connection parts are as follows: ① Left and right connecting parts. This design also includes two design options for the left and right connecting parts: One of the ways is as follows Figure 1 To the attached Figure 3 As shown, concave connecting grooves 9 are designed on the end faces on both sides of the wall panel body. When the two wall panel bodies are spliced ​​together, the two concave connecting grooves 9 will be spliced ​​together to form a square grouting groove. By pouring concrete inside, a post-cast structural column 13 is formed to fix the two wall panel bodies. When multiple wall panel bodies are spliced ​​into a circle, a stable circle is formed by pouring the post-cast structural column 13. Although the inner groove connecting groove is square in the drawings, the design of a semicircular or special shape is a simple replacement of the technical solution. Another way is as follows Figure 4 As shown, multiple threaded connection boxes 10 are embedded on the outer facades on both sides of the wall panel body. During the splicing process, bolts are inserted from the threaded connection box 10 on one side into the threaded connection box 10 on the other side, and nuts are used to fix the two ends, thereby fixing the two wall main boards together. Of the two methods, for those with high strength requirements and long-term use, it is recommended to use the concave connection groove 9. If it is just a temporary construction with low strength requirements and the desire for quick construction and low cost, the threaded connection box 10 can be used.

[0031] ② For the upper and lower connecting parts, the main consideration is that there should be no shaking during use and the integrity should be better. Therefore, the post-casting method is used in this design scheme for connection, as shown in the attached Figure 1 To the attached Figure 3 As shown, corresponding post-cast structures are designed at the upper and lower ends of the wall panel body, and a sleeve grouting connection channel 7 is provided below the wall panel body. The sleeve grouting connection channel 7 is in the shape of a hook, one end of which is located at the lower end of the wall panel body, and the other end is located on the outer facade of the wall panel body. In order to avoid affecting the arc filling block 4, the sleeve grouting connection channel 7 is located between the two arc filling blocks 4.

[0032] A circular arc-shaped connecting grouting groove 8 is provided above the wall panel body. Both ends of the connecting grouting groove 8 are open. After the splicing is completed, it can form a circular grouting groove with the connecting grouting grooves 8 on other wall panel bodies, so that concrete can flow inside and ensure its integrity after solidification.

[0033] Method for manufacturing the main part of the wall panel in Example 1: The wall panel body of this design can be manufactured using a traditional method, which involves building an arc-shaped inner mold and side molds, then pouring the arc-shaped inner panel 2. After the concrete solidifies, an arc-shaped filling block 4 is placed on the arc-shaped inner panel 2, and then an upper mold is built for secondary pouring, forming the longitudinal ribs, transverse ribs, and arc-shaped outer panel 3 at one time. Although this method is fast in manufacturing speed, the pouring results show that the arc-shaped filling blocks often move during the secondary pouring process, and the curved outer panel 3 on the facade has a discontinuous surface. Therefore, in this design scheme, a manufacturing method for the wall panel body of this design scheme is also designed. This method adopts the superposition method, and its specific steps are as follows: Step 1: Build an arc-shaped inner mold and outer mold, and adjust the distance between the inner mold and the outer mold so that the inner mold and the outer mold are coaxially distributed; Step 2: Build side molds on both sides of the inner mold and the outer mold so that the space they form is the same shape as the wall panel body 1 and the size meets the construction requirements; Step 3: Casting is performed in the constructed casting mold to cast the bottom layer of the wall panel body 1, that is, the casting transverse ribs of the end surface; Step 4: After the bottom layer of the wall panel body 1 solidifies, place several arc-shaped filling blocks 4 at the corresponding positions on the upper end of the bottom layer and pour again until the concrete is higher than the designed distance (the designed distance is the height of the transverse rib) above the upper surface of the arc-shaped filling blocks 4, then stop pouring; Step 5: Repeat step 4 until the entire wall panel body 1 is cast; Step 6: After the entire wall panel body 1 solidifies, remove the inner mold, outer mold and side mold to complete the processing of the wall panel body 1.

[0034] For the above-mentioned processing method, when the left and right connecting parts adopt the inner groove method, the shape of the side mold needs to be installed in an inner groove manner, or the corresponding mold needs to be placed to ensure that there are inner grooves on both sides after the pouring is completed. When the threaded connection box 10 is used, it is placed together with the arc-shaped filling block 4 during the pouring process, and then poured, so that it can be embedded in the wall panel body 1.

[0035] When pouring the top layer, the corresponding mold needs to be placed in advance so that the connecting grouting groove 8 is formed after the concrete cools.

[0036] Example 2 As attached Figure 7 To the attached Figure 11As shown, the present design also includes a silo constructed by Example 1. The silo of Example 1 specifically includes a multi-layer silo assembly layer fixedly connected by upper and lower connecting parts. The silo assembly layer is composed of a plurality of wall panel bodies 1 in a circular array, and both sides of the wall panel body 1 are connected by left and right connecting parts.

[0037] The construction method of the silo is as follows: Step 1: Mark the construction site and plan the location of each curved ribbed sandwich wall panel; Step 2: Use a crane to hoist the curved ribbed sandwich wall panel to the pre-planned location and support it with formwork; Step 3: Use the left and right connecting parts to fix and connect the adjacent curved multi-rib sandwich wall panels. After all the fixing and connection are completed, the first layer of the silo assembly layer is obtained; If the left and right connecting parts adopt the concave connecting groove 9, after step 2 is completed, the concave connecting grooves 9 on the two adjacent wall panels are spliced ​​into a square groove, concrete is poured, and after cooling, a post-cast structural column 13 is formed to ensure the integrity of the silo assembly layer. Figure 7 To the attached Figure 9 As shown, If the left and right connecting parts are threaded connection boxes 10, after step 2 is completed, the bolts are passed through the threaded connection box 10 on one wall panel body to the threaded connection box 10 on the other wall panel, and the two ends are fixed with nuts to achieve the stability of the silo assembly layer, as shown in the attached figure. Figure 10 To the attached Figure 11 As shown,.

[0038] Step 4: Build the formwork to form the silo assembly position on the upper level; Step 5: Use a crane to hoist the curved dense rib sandwich wall panels onto the curved dense rib sandwich wall panels of the next layer, and hoist them one by one to form the upper silo assembly layer; Step 6: Use the left and right connecting parts to fix and connect the adjacent curved multi-rib sandwich wall panels. After all the connections are completed, the upper silo assembly layer is obtained. Step 7: Concrete is injected through the sleeve grouting connection channel 7, thereby fixing the upper layer and the lower layer and improving the integrity of the silo; In this step, the injected concrete enters the connecting grouting groove 8 at the upper end of each wall panel body 1. Since the silo assembly layer is circular, multiple connecting grouting grooves 8 form a large circular grouting groove, allowing the concrete to flow at the upper end of each wall panel body and finally form a post-cast ring beam 12 after solidification. As a result, the silo has stronger integrity and better impact resistance, earthquake resistance and wind resistance. At the same time, in order to strengthen the overall strength of the post-cast ring beam 12, when the circular grouting groove is formed in step 3, a circular steel pipe 11 is placed inside, so that when the post-cast ring beam 12 is formed, the strength will be stronger. Figure 8 With attached Figure 9 shown.

[0039] Step 8: Repeat steps 4 to 5 until the entire silo is assembled and then remove the mold.

Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
