Description

Technical Field

[0001] The present invention relates to the technical field of shallow silos, and specifically to a jack-up prefabricated shallow silo wall panel and its construction process. Background Art

[0002] Grain silos are important facilities for ensuring food security and emergency reserves. In the modernization development of grain storage, shallow silos are widely used due to their small floor area, strong earthquake resistance, reasonable structural stress, and good sealing performance. A shallow silo refers to a cylindrical above-ground grain silo with a ratio of height to diameter less than 1.5, mostly made of concrete structure, and generally with a diameter between 18 - 35m.

[0003] The existing construction process for shallow silos is slip form construction, and the implementation method is to climb while curing the cast concrete.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manners.

[0046] Please refer to Figures 1 to 13 , in the embodiment of the present invention, a jacking and assembled shallow round silo wall panel includes:

[0047] The foundation 1 is circularly arranged, and a groove is formed by inward depression at the top of the foundation 1. The self-jacking and assembled shallow round silo wall panel 2 and the prestressed silo wall panel 3 are embedded in the groove, and a silo top 4 is installed on the silo wall panel 2 and the prestressed silo wall panel 3;

[0048] A storage wall outer wall niche 31 is formed on the prestressed storage wall panel 3. A storage wall inner wall niche 25, a storage wall perimeter wall niche 23, bolt holes 24, and prestressed steel bar holes 22 are formed on the storage wall panel 2. A connecting member is formed on the storage wall panel 2. The connecting member connects multiple storage wall panels 2 and the prestressed storage wall panel 3 in the horizontal direction through the prestressed steel bar holes 22 and the storage wall outer wall niche 31. Each storage wall panel 2 and the prestressed storage wall panel 3 are arc-shaped and are arranged in a circular pattern within the groove formed by the foundation 1. The connecting member includes prestressed steel bars 5 that penetrate through the prestressed steel bar holes 22 and the storage wall outer wall niche 31.

[0049] Specifically, during construction, first, the circular foundation 1 is cast in place. After the construction of the foundation 1 is completed, the storage wall panels 2 are arranged along the perimeter of the foundation 1, and one prestressed storage wall panel 3 is arranged for every three storage wall panels 2.

[0050] After the first layer of storage wall panels is arranged, the prestressed steel bars are arranged. Each prestressed steel bar 5 connects five storage wall panels, including three storage wall panels 2 and two prestressed storage wall panels 3. The prestressed steel bar 5 starts to penetrate from the storage wall outer wall niche 31 on the left side of the prestressed storage wall panel 3, penetrates through 3 storage wall panels 2, and then connects to another prestressed storage wall panel 3, and exits from the storage wall outer wall niche 31 on the right side of the other prestressed storage wall panel 3, forming a prestressed range.

[0051] A total of twelve prestressed steel bars 5 are used for each layer of storage wall panels 2. Each storage wall panel 2 and prestressed storage wall panel 3 has six prestressed steel bar holes 22. Every two prestressed steel bar holes 22 form a group, and are divided into three different height ranges. Within one height range, after one prestressed steel bar 5 is arranged, another prestressed steel bar hole 22 within a group of prestressed steel bar holes 22 can be used to continue arranging the prestressed steel bar 5. Each height is arranged in a relay and alternating manner to ensure that each storage wall panel 2 has prestress in three different height ranges, and the arrangement form of the prestressed steel bars 5.

[0052] After the prestressed steel bars 5 are arranged, the tensioning equipment starts to tension the prestressed steel bars 5 to apply prestress, then the anchor bars are anchored and the filling plate 32 is covered. Finally, bolts 6 for connecting in the horizontal direction are arranged through the bolt holes 24.

[0053] Fixing members are arranged within the bolt holes 24. The fixing members are used to connect multiple storage wall panels 2 in the vertical direction and connect the storage top 4 and the storage wall panels 2 to each other. The fixing members include bolts 6 that are movably installed within the bolt holes 24 and are matched with the storage top 4.

[0054] It should be noted that after the prestress is applied to the first-layer bulkhead plate 2 and the bolts 6 are connected, the construction of the silo top 4 starts above the first-layer bulkhead plate 2. The prestressed bolt holes 24 at the lower part of the silo top 4 can be connected to the bulkhead plate 2 by high-strength bolts 6.

[0055] After the construction of the silo top 4 is completed, the lifting of the first-layer bulkhead plate 2 starts; each lower part of the bulkhead plate 2 contains an airbag body 21, and a highly resilient full-fat sponge in a compressed state is arranged inside the airbag body 21. After the air valve 27 is opened, the highly resilient full-fat sponge in the compressed state will absorb air and expand in volume, thus lifting the upper bulkhead plate 2. The height of the highly resilient full-fat sponge in the airbag body 21 after completely absorbing air is the same as that of the bulkhead plate 2. In this state, the airbag body 21 can be replaced with the bulkhead plate 2.

[0056] After the airbag body 21 is automatically inflated, the air valve 27 is closed. At this time, the height of the inflated airbag 26 is the same as that of the bulkhead plate 2; the assembly of the second-layer bulkhead plate 2 starts. The inflated airbag 26 lifts the height of one bulkhead plate 2. The airbag bodies 21 among them are removed one by one and replaced with bulkhead plates 2 until all the airbag bodies 21 in one layer are replaced with bulkhead plates 2. The prestressed steel bars 5 and bolts 6 of the second layer start to be arranged. The arrangement forms of the bulkhead plates 2 and the prestressed steel bars 5 of each layer are the same. The bulkhead plates 2 of each layer are connected by vertical bolts 6 in the niches 25 on the inner side of the bulkhead.

[0057] Then, the operations of airbag lifting - removing and replacing the airbag with the bulkhead plate 2 - arranging the prestressed steel bars 5 and bolts 6 - airbag lifting are repeated until the assembly of all the bulkhead plates 2 is completed.

[0058] An airbag body 21 is installed below the bulkhead plate 2, and an inflation structure is arranged inside the airbag body 21. The inflation structure includes an air injection pipe 7 fixedly installed inside the airbag body 21. An air delivery groove 71 is formed on the side wall of the air injection pipe 7, and a pressure pipe 72 is fixed at the end of the air injection pipe 7.

[0059] The rotating rod 8 is rotatably installed in the air pressure tube 72 and penetrates through the charging tube 7. An air pressure pushing mechanism is arranged in the air pressure tube 72. A sealing disc 94 is connected to the air pressure pushing mechanism. When the air pressure in the airbag body 21 increases, the sealing disc 94 can move along the length direction of the rotating rod 8 to control the rotation of the rotating rod 8 through the air pressure pushing mechanism. The air pressure pushing mechanism includes support sleeves 9 fixedly installed in the air pressure tube 72 and arranged symmetrically. An active rod 91 is movably installed in the support sleeve 9. The active rod 91 is fixedly connected to the sealing disc 94. A guiding component and an elastic component connected to the sealing disc 94 are arranged on the rotating rod 8. Among them, the guiding component includes a straight groove 81 and an annular groove 82 formed on the rotating rod 8. The end of the straight groove 81 is connected to the end of the annular groove 82. A third protrusion 95 slidably connected to the straight groove 81 and the annular groove 82 is fixed in the sealing disc 94. The above-mentioned elastic component includes an active plate 92 slidably installed on the support sleeve 9 and sleeved on the rotating rod 8. A first spiral groove 83 is formed on the rotating rod 8. A second protrusion 93 slidably connected to the first spiral groove 83 is fixed in the active plate 92. A spring 10 is sleeved on the rotating rod 8. Two ends of the spring 10 respectively abut against the sealing disc 94 and the active plate 92.

[0060] Furthermore, in the initial state, the spring 10 is in a compressed state, so that the sealing disc 94 is located at the end of the stroke in the direction away from the charging tube 7, so that the third protrusion 95 is located at the end of the stroke in the direction away from the annular groove 82 of the straight groove 81, and the second protrusion 93 is located at the end of the stroke on the side of the first spiral groove 83 facing the annular groove 82. In order to accelerate the expansion of the sponge body filled in the airbag body 21, it is necessary to inflate the airbag body 21. At this time, the inflation port of the inflator can be inserted into the charging tube 7, and the air will be conveyed to the airbag body 21 through the air supply groove 71. As the gas in the airbag body 21 increases, the air pressure in the air pressure tube 72 increases, and the sealing disc 94 is controlled to move in the direction of the charging tube 7, so that the third protrusion 95 moves along the length direction of the straight groove 81. The sealing disc 94 will also drive the active rod 91 to move along the length direction of the support sleeve 9 to ensure that the sealing disc 94 will not shift during movement. The sealing disc 94 will also compress the spring 10. When the air pressure reaches a certain level, the third protrusion 95 just moves to the connection position of the straight groove 81 and the annular groove 82, and the compression amount of the spring 10 reaches the maximum. At this time, the spring 10 elastically releases and controls the active plate 92 to move in the direction of the charging tube 7. The active plate 92 will also control the second protrusion 93 to slide in the first spiral groove 83, so that the rotating rod 8 rotates, so that the third protrusion 95 enters the annular groove 82, so as to eject the inflation port through the ejection component.

[0061] The ejection assembly is arranged in the inflation tube 7 and connected to the rotating rod 8. When the rotating rod 8 rotates, the inflation head can be ejected. The ejection assembly includes a second spiral groove 84 provided on the rotating rod 8, and a push plate 85 is movably installed on the rotating rod 8. A No. 1 protrusion 86 that is slidably connected to the second spiral groove 84 is fixed in the push plate 85; it also includes a limit groove 73 provided in the inflation tube 7, and a limit block 87 that is slidably connected to the limit groove 73 is fixed on the outer wall of the push plate 85.

[0062] Furthermore, after the airbag body 21 expands to a certain size, it is necessary to control the gas from entering the airbag body 21. In the initial state, the push plate 85 is located at the end of the stroke in the inflation tube 7, so that the air supply groove 71 is in a conducting state, and the No. 1 protrusion 86 is located at the end of the stroke on one side of the second spiral groove 84. At this time, the inflation port can be inserted into the inflation tube 7. As the inflation amount gradually increases, the sealing plate 94 will move, so that the No. 3 protrusion 95 moves to the connection position between the straight groove 81 and the annular groove 82. The spring 10 is elastically released and controls the rotation of the rotating rod 8 through the No. 2 protrusion 93 and the first spiral groove 83, thereby controlling the push plate 85 to move toward the outside of the inflation tube 7 through the second spiral groove 84 and the No. 1 protrusion 86. Since the limit groove 73 and the limit block 87 are slidably connected, it is ensured that the push plate 85 will not deviate during movement. Under the action of the push plate 85, the inflation port is pushed to the outside of the inflation tube 7.

[0063] A construction process for a jacking-up assembled shallow round silo wall panel comprises the following steps:

[0064] Step 1: First, cast the annular foundation 1 in situ, and after the construction of the foundation 1 is completed, arrange the warehouse wall panels 2 along the circumference of the foundation 1, and arrange a prestressed warehouse wall panel 3 for every three warehouse wall panels 2;

[0065] Step 2: The prestressed steel bar 5 is passed through the left side niche 31 of the prestressed warehouse wall plate 3, and then connected to another prestressed warehouse wall plate 3 after passing through three warehouse wall plates 2, and then passed out from the right side niche 31 of the other prestressed warehouse wall plate 3 to form a prestressed range;

[0066] Step 3: After the prestressed steel bars 5 are arranged, the steel bars 5 are anchored and covered with a filling plate 32, and finally the bolts 6 in the horizontal direction are arranged through the bolt holes 24;

[0067] Step 4: construct the warehouse roof 4 above the first warehouse wall plate 2. The lower ring beam of the warehouse roof 4 has bolt holes 24, which can be connected to the warehouse wall plate 2 by high-strength bolts 6;

[0068] Step 5: After the construction of the silo top 4 is completed, open the air valve 27 on the airbag body 21, and inflate the airbag body 21 through the inflation structure. Under the action of the airbag body 21, lift the upper silo wall panel 2 until its height is the same as that of the silo wall panel 2. Then, the airbag body 21 can be removed and replaced with the silo wall panel 2, and start to arrange the second layer of silo wall panels 2. Repeat the above steps until all the silo wall panels 2 are assembled.
