Description

Technical Field

[0001] The utility model belongs to the technical field of tank installation at construction sites, and particularly relates to a vertical tank bottom fixing structure. Background Art

[0002] At present, many occasions require the use of super-tall tank equipment to store water or materials. The installation methods of the tank include fixed installation such as pre-cast concrete and detachable installation such as bolt connection. The civil construction site has a certain time limit, that is, when the construction site is moved away after a certain period of time, the tank needs to be removed. Therefore, the tanks at the civil construction site are all installed in a detachable manner. Specifically, the bottom of the tank at the civil construction site is provided with a mounting base plate that protrudes radially from the outer wall of the tank body. The mounting base plate is provided with a through hole. The fastening bolts pass through the through hole and are locked with nuts to lock the tank in the installation position.

[0003] Since the total weight of the tank and its contents is relatively large, the mounting plate at the bottom of the tank has a large bearing capacity. If the mounting plate is not thick enough, the mounting plate is easily broken or cracked when the tank is subjected to external forces. In order to make the tank stand firmly in the installation position and avoid safety accidents such as the tank tipping over, the mounting plate at the bottom of the tank in the prior art is usually set very thick to accommodate the large mass of the tank. The thicker mounting plate not only increases the weight of the tank, but also requires more materials for the tank, which is more expensive. Utility Model Content

[0035] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0036] The utility model provides a vertical tank bottom fixing structure, comprising a bottom plate 2, a thickened portion 3, anchor bolts 4 and a nut assembly 5, wherein:

[0037] The bottom plate 2 is integrally formed with the tank body 1, and the bottom plate 2 is arranged on the bottom outer wall of the tank body 1 along the radial direction of the tank body 1. The bottom plate 2 is provided with through holes 21 for passing bolts. It should be noted that there are multiple through holes 21, and the multiple through holes 21 are evenly distributed around the tank body 1. The thickened portion 3 is placed on the bottom plate 2, and the bottom surface of the thickened portion 3 is fixedly connected to the top surface of the bottom plate 2, and the side surface of the thickened portion 3 is fixedly connected to the outer wall of the tank body 1, so that the thickened portion 3 is not only fixedly connected to the bottom plate 2, but also fixedly connected to the side surface of the tank body 1. One of the above-mentioned thickened portions 3 is arranged at each through hole 21. A through hole 321 coaxial with the through hole 21 is provided in the thickened portion 3. The size and shape of the through hole 321 correspond to those of the through hole 21. The through hole 321 is located directly above the through hole 21. The through hole 321 and the through hole 21 form a hole for passing the anchor bolt 4. The anchor bolt 4 is buried in the ground. Of course, the threaded section of the anchor bolt 4 extends upward from the ground. During installation, the anchor bolt 4 passes through the through hole 21 and the through hole 321 from bottom to top in sequence and is then screwed to the nut assembly 5. Then, the nut assembly 5 is used to press the thickened portion 3 and the bottom plate 2 against the ground.

[0038] Through the above structure, the thickened portion 3 fixed between the top surface of the bottom plate 2 and the side of the tank body 1 and the bottom plate 2 jointly bear the fastening force of the tank body 1, and the thickened portion 3 is also fixedly connected to the side of the tank body 1, thereby increasing the contact area between the fixed structure and the tank body 1. In this way, the force-bearing area of ​​the entire fixed structure and the tank body 1 is larger, thereby providing a greater bearing capacity. Based on this, the thickened portion 3 is provided so that the bottom plate 2 does not need to be too thick, and the thickened portion 3 is only provided at the position corresponding to the above-mentioned through hole 21. Therefore, while ensuring that the tank body 1 can be provided with sufficient bearing capacity and installation fastening force, the fixed structure is lighter in weight, has less consumables, and is highly practical. Moreover, since the contact area between the fixed structure and the tank body 1 is larger, a smaller number of through holes 21 can be opened on the bottom plate 2, and the tank body 1 can be fixed to the ground using a smaller number of anchor bolts 4 and nut assemblies 5. Therefore, the bottom fixing structure of the vertical tank body 1 provided by the utility model can also save the number of anchor bolts 4 and nut assemblies 5, thereby reducing the workload of the installer when installing the tank body 1.

[0039] An optional implementation of this embodiment is as follows: the thickened portion 3 includes a support plate 31 and a fixing plate 32, wherein:

[0040] The support plate 31 and the fixing plate 32 are both plates supported by hard materials. Optimally, the materials of the support plate 31 and the fixing plate 32 are the same as those of the tank body 1. Of course, the materials of the support plate 31 and the fixing plate 32 may also be different from those of the tank body 1. The bottom surface of the support plate 31 is fixedly connected to the top surface of the bottom plate 2, the side surface of the support plate 31 is fixedly connected to the outer wall of the tank body 1, the bottom surface of the fixing plate 32 is fixedly connected to the top surface of the support plate 31, the side surface of the fixing plate 32 is fixedly connected to the outer wall of the tank body 1, and the through hole 321 is provided in the fixing plate 32. The support plate 31 acts as a support member to fix the fixing plate 32 between the top surface of the bottom plate 2 and the outer wall of the tank body 1, and the fixing plate 32 is also fixedly connected to the outer wall of the tank body 1, so that the connection area between the thickened portion 3 and the bottom plate 2 and the tank body 1 is larger. Optionally, the support plate 31 and the fixing plate 32 in this embodiment are both flat plates, and the fixing plate 32 is arranged parallel to the bottom plate 2 to facilitate the connection of the anchor bolts 4 and the nut assembly 5. Of course, the fixing plate 32 may also be an arc-shaped plate, or a special-shaped plate with a protrusion on the top surface.

[0041] As another implementation of this embodiment, the thickened portion 3 in this embodiment can also be a whole block structure, and its manufacturing material is the same as that of the bottom plate 2 and the tank body 1.

At this time, the fixed plate 32 and the two support plates 31 form a door-type structure. The thickened portion 3 of such a structure has a greater structural strength, and cooperates with the bottom plate 2 to provide bearing capacity for the installation of the tank body 1. Of course, the number of the above-mentioned support plates 31 can also be one or three or four or more. When the number of the support plates 31 is one, the fixed plate 32 is connected to the top of the support plate 31, and the fixed plate 32 and the support plate 31 form a "7"-shaped structure. At this time, a reinforcing rib needs to be set between the fixed plate 32 and the support plate 31, and the reinforcing rib is not located between the through hole 321 and the through hole 21.

[0043] More preferably, a diagonal brace plate 33 is further provided in the door-type structure composed of the support plate 31 and the fixed plate 32. Specifically, the top end of the diagonal brace plate 33 is fixedly connected to the fixed plate 32, and the bottom end of the diagonal brace plate 33 is fixedly connected to the bottom plate 2. The diagonal brace plate 33 is actually also a part of the thickened portion 3, and the through hole 321 also penetrates the diagonal brace plate 33. With the help of the diagonal brace plate 33, the fixed plate 32 is directly fixedly connected to the bottom plate 2, further enhancing the structural strength of the thickened portion 3. Optimally, the number of the diagonal brace plates 33 is two, and the two diagonal brace plates 33 form an "X"-shaped structure in the door-type structure, so that the bearing capacity of the thickened portion 3 is stronger. Of course, a vertical plate can also be used to replace the diagonal brace plate 33.

[0048] When the fixed connection method between the support plate 31 and the tank body 1, the bottom plate 2 and the fixing plate 32 is welding, in this embodiment, a stress release hole 311 is opened on the side of the support plate 31 close to the tank body 1. The stress release hole 311 is used to release the internal stress generated during the welding process, thereby avoiding stress concentration at the connection between the thickened portion 3 and the tank body 1 and the bottom plate 2.

[0049] An optional implementation of this embodiment is as follows: the nut assembly 5 includes a first nut 51 and a second nut 52, wherein:

[0050] The first nut 51 and the second nut 52 are both screwed onto the stud section of the anchor bolt 4, and the first nut 51 is located between the second nut 52 and the fixing plate 32.
