Description

Technical Field

[0001] This utility model relates to the field of ribless water tanks, and in particular to a ribless water tank external groove connector. Background Technology

[0002] Water tanks, as containers for storing water, are widely used in factories, mines, enterprises, residences, hotels, restaurants, and other places. Currently, Chinese patent application number CN214493742U discloses an embedded, unreinforced water tank, including a tank body. The tank body is composed of a base frame, a bottom plate, side plates, a top plate, a first vertical support, a second vertical support, and connecting ribs. The top plate is composed of multiple top surface templates spliced ​​together, with raised sections facing outwards from the tank body. The bottom plate is composed of multiple cold-rolled steel plates spliced ​​together, and the side plates are composed of multiple side side templates spliced ​​together. The tank body is equipped with a first vertical support, a second vertical support, and connecting ribs for supporting the tank body. A base frame is located below the bottom plate, and a concrete beam foundation for the water tank is located below the base frame. Adjacent side templates form a groove structure after splicing. Connecting ribs are placed within the grooves formed by splicing adjacent side templates and are used to connect two adjacent side templates. The first vertical support is placed within the grooves formed by splicing adjacent side templates. The first and second vertical supports are placed in the vertical grooves formed when the side templates are assembled on the same side, and the second vertical support is placed in the vertical grooves formed when the two side templates are assembled on adjacent sides. An inspection port is provided on any one of the top templates, and a box cover is installed on the inspection port. An internal ladder is provided below the inspection port and is installed on the side template. An external ladder is installed on the other side of the side template with the internal ladder. The profiles used for the first and second vertical supports are square steel, channel steel, I-beams, or steel plates, etc. The first and second vertical supports are connected to the top plate and bottom plate by welding, bolts, etc. The first and second vertical supports can be completely embedded in the grooves formed by the side templates, or they can be partially embedded in the grooves formed by the side templates and partially protrude from the grooves formed by the side templates.

[0003] Currently, our company previously used a system where the vertical grooves between the side panels of the water tank were equipped with a first vertical support and a second vertical support, which were welded and fixed into the vertical grooves in conjunction with U-shaped connecting ribs. This method of connecting vertical supports still requires welding during use, and any subsequent disassembly or replacement of the vertical supports and connecting ribs requires cutting and welding the welded positions, which is very troublesome.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4A type of unreinforced water tank external groove connector includes a vertical support rod 2 disposed between adjacent water tank side plates 1, and a concrete support 3 supporting the water tank side plates 1. A bottom abutment plate 4 is fixedly connected to the bottom of the vertical support rod 2, and a plug rod 5 is fixedly connected to the bottom of the bottom abutment plate 4. A pre-embedded opening 6 is provided at the upper end of the concrete support 3, and a base 7 is installed inside the pre-embedded opening 6. An installation opening 9 communicating with the inner cavity is provided through the upper end of the base 7. A locking sleeve 10 is rotatably connected to the upper end of the installation opening 9 through a bearing. The plug rod 5 moves through the locking sleeve 10 and the installation opening 9 and extends to the inner cavity of the base 7. The surface of the plug rod 5 is provided with a smooth surface and a threaded surface from bottom to top. The smooth surface at the bottom of the plug rod 5 slides through the locking sleeve 10. The threaded surface at the bottom of the plug rod 5 is threadedly connected to the locking sleeve 10. A limit groove 501 is provided longitudinally on the outer side of the plug rod 5, and a limit pin 901 is fixedly connected to the inner wall of the installation opening 9. The limit pin 901 is engaged with the limit groove 501.

[0023] Based on this, when the device is in use, a connecting component is also provided on the outside of the adjacent water tank side plate 1. The connecting component refers to the connecting structure of the adjacent water tank side plate 1 in the prior art. The vertical support rod 2 replaces the vertical support in the prior art. There is no difference in the structural design between the two. The only difference is that an abutment plate 4 and a plug rod 5 are added to the bottom of the two. At the same time, the U-shaped connecting ribs that are used to reinforce the vertical support in the prior art are removed.

[0024] During use, the workers first cast the base 7 into the pre-embedded opening 6 at the upper end of the concrete support base 3. Then, the vertical support rod 2 is inserted into the groove between the adjacent water tank side plates 1 and fits against the inner wall of the groove. During the insertion of the vertical support rod 2, its bottom insertion rod 5 aligns with the mounting opening 9 at the upper end of the base 7. At the same time as the insertion rod 5 is inserted into the mounting opening 9, the outer limiting groove 501 of the insertion rod 5 aligns with the limiting block 901 on the inner wall of the mounting opening 9. Furthermore, during the downward insertion of the insertion rod 5, the smooth surface on the outer side of the insertion rod 5 is pre-pierced. Insert the locking sleeve 10 into the installation port 9, then mate the threaded surface of the plug rod 5 with the locking sleeve 10, rotate the locking sleeve 10 and drive the plug rod 5 with the thread to lower the plug rod 5 until the abutment plate 4 at the bottom of the vertical support rod 2 abuts against the upper end of the locking sleeve 10 to complete the overall assembly. The whole process is relatively convenient and does not require welding. It is also very convenient to disassemble and repair the vertical support rod 2 without cutting. At the same time, after the above structure is installed, it can be understood that the vertical support rod 2 and the concrete support base 3 are fixed together, and its stability is also guaranteed.

[0025] The contact surfaces of the limiting pin 901 and the limiting groove 501 are both designed to be smooth. During the longitudinal lifting and lowering process of the locking sleeve 10 adjusting the plug rod 5, the smooth surface design can reduce the friction between the limiting groove 501 on the outer side of the plug rod 5 and the limiting pin 901, and make the plug rod 5 slide smoothly.

[0026] The base 7 has side ribs 701 fixedly connected to its four sides. Both the base 7 and the outer side ribs 701 are cast and fixed inside the pre-embedded opening 6. Furthermore, the side ribs 701 are perpendicular to the side walls of the base 7. This increases the contact surface between the base 7 and the pre-embedded opening 6 in the concrete support 3, thus enhancing the overall strength of the base 7. Additionally, a support plate 8 is fixedly connected to the outer side of the upper end of the base 7. The support plate 8 is fitted and fixed to the upper end of the concrete support 3. A bolt 801 is threaded through the upper end of the support plate 8, and a threaded hole 802 corresponding to the bolt 801 is provided on the upper end of the concrete support 3. The support plate 8 is fixed to the upper end of the concrete support 3 by threading the bolt 801 into the threaded hole 802.

[0027] The bottom of the abutment plate 4 abuts against the upper end of the locking sleeve 10, and a rubber pad is provided at the bottom of the abutment plate 4. After the locking sleeve 10 fixes the insertion rod 5 at the bottom of the abutment plate 4, the vertical support rod 2 is then fixedly installed. The abutment plate 4 abuts against the upper end of the locking sleeve 10, and the rubber pad at the bottom can increase the sealing effect of the connection, preventing outdoor rainwater from seeping into the locking sleeve 10. At the same time, the bearing at the bottom of the locking sleeve 10 is preferably a sealed bearing, which increases the overall sealing performance and achieves the effect of outdoor waterproofing and dustproofing.

[0028] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
