Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated water tank construction technology, and in particular to a connecting bolt for prefabricated side plates of ultra-high prefabricated water tanks. Background Technology
[0002] Water tanks can be used in various fields, such as fire protection systems, industrial systems, agricultural systems, and other aspects of daily life. However, because cast-in-place concrete water tanks are constructed by building structures like tank walls and trenches using wooden planks, and then pouring concrete grout into them and allowing it to solidify, construction of cast-in-place concrete water tanks has disadvantages such as high consumption of formwork, long on-site work time, significant susceptibility to weather conditions, and unstable concrete quality. Therefore, various types of prefabricated water tanks with different structural designs have emerged on the market.
[0003] The construction process of prefabricated water tanks involves: pouring a foundation; assembling several precast slab units into side panels within pre-reserved mounting slots on the foundation; and then laying a top slab at the ends of the side panels. Currently, the side panel height of ordinary prefabricated water tanks is approximately 3 meters. Due to limitations in land space, the volume of prefabricated water tanks is limited, thus ordinary prefabricated water tanks have a certain water storage capacity shortage when supplying water for large-scale fires. To meet the large water supply demands of urban fire-fighting water supply systems, ultra-high prefabricated water tanks (side panel height > 3 meters) are gradually becoming popular.
[0004] Precast side panel units used for assembling standard prefabricated water tank side panels are mostly precast slabs with an integrated structural design. These are manufactured in the factory and then transported to the construction site for assembly. Because the side panel height of ultra-high prefabricated water tanks is significantly increased compared to standard prefabricated water tank side panels, designing the precast side panel units for ultra-high prefabricated water tank side panels as integrated slabs would result in a substantial increase in weight, consequently increasing the difficulty of hoisting and transportation. Therefore, precast side panels used for assembling ultra-high prefabricated water tanks are typically constructed by connecting two precast side panel units with a connecting assembly to form a single precast side panel unit with an internal casting cavity, thereby reducing weight and facilitating transportation. However, currently, there are no dedicated connecting assemblies available on the market for connecting precast side panel units of ultra-high prefabricated water tanks. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a connecting bolt for the prefabricated side plate of an ultra-high assembled water tank.
[0006] The purpose of this utility model is achieved through the following technical solution: A connecting bolt for prefabricated side panels of ultra-high assembled water tanks, including a screw a, one end of the screw a being coaxially connected to the end of the screw b via a connecting nut, the other end of the screw a being provided with a fixing plate, and a water-stop plate and a positioning sleeve being fitted on the outside of the screw a, the positioning sleeve being located between the water-stop plate and the connecting nut, and a washer pressure plate and a locking nut being installed on the outside of the screw b, the washer pressure plate being located between the connecting nut and the locking nut.
[0007] Preferably, the waterstop plate has notch grooves a on the upper and lower sides, and eaves plates are provided on the left and right sides, with notch grooves b on the eaves plates.
[0008] Preferably, the bending direction of the eaves is consistent with the axial direction of the screw a.
[0009] Preferably, the waterstop plate has a screw hole, the screw a passes through the screw hole, and a hexagonal nut a is provided on the side of the waterstop plate, which is coaxial with the screw hole.
[0010] Preferably, the surface of the screw a is provided with a threaded section, the outer surface of the threaded section is provided with a pre-embedded section, the waterstop plate and the positioning sleeve are both installed on the threaded section, and the fixing plate is installed at the end of the pre-embedded section.
[0011] Preferably, the connecting nut is provided with an internal threaded hole a and an internal threaded hole b, the end of the threaded segment is located in the internal threaded hole a, the end of the screw b is located in the internal threaded hole b, and the internal threaded hole a and the internal threaded hole b are connected.
[0012] Preferably, the diameter of the internal threaded hole a is larger than the diameter of the internal threaded hole b.
[0013] Preferably, the side of the connecting nut is provided with a hexagonal nut b that is coaxial with the internal thread hole b.
[0014] Preferably, a circumferential groove is provided on the outer surface of the connecting nut.
[0015] This utility model has the following advantages:
[0016] 1. This utility model involves vertically embedding a fixing plate into a precast side plate a, attaching a reinforcing cage to the side surface of the precast side plate a where the other end of the screw a extends, and then attaching the precast side plate b to the other side surface of the reinforcing cage. The end of the screw b is coaxially connected to the screw a via a connecting nut, and a locking nut is used to press and fix the washer plate to the outer surface of the precast side plate b. This allows the precast side plate a, precast side plate b, and reinforcing cage to be tightly connected to form a precast side plate unit for an ultra-high prefabricated water tank. One end of the positioning sleeve rests against the waterstop plate, and the other end rests against the precast side plate b, enabling precise control of the distance between the precast side plate a and precast side plate b. This ensures that the thickness of the precast side plate unit of the ultra-high prefabricated water tank is uniform, and the screw b can be reused, thus saving on the construction cost of the ultra-high prefabricated water tank.
[0017] 2. This utility model has a fixing plate at one end of the screw a. When the fixing plate is embedded in the prefabricated side plate a, the pre-embedding firmness of the screw a in the prefabricated side plate a can be improved. The waterstop plate is spirally installed on the screw a. The position of the waterstop plate can be flexibly adjusted during use, so as to ensure that the positioning sleeve can effectively abut between the waterstop plate and the prefabricated side plate b. This makes the connecting bolts of this utility model applicable to the prefabricated side plate units of ultra-high assembled water tanks of different thicknesses.
[0018] 3. This utility model provides notch grooves a on the upper and lower sides of the waterstop plate and eaves plates on the left and right sides of the waterstop plate. Notch grooves b are provided on the eaves plates. The main function of the eaves plates, notch grooves a and notch grooves b is to effectively improve the interlocking force between the waterstop plate and the concrete poured into the casting cavity inside the precast side plate unit, thereby effectively improving the overall firmness of the precast side plate unit of the ultra-high prefabricated water tank.
[0019] 4. This utility model provides an circumferential groove on the outer side of the connecting nut. The circumferential groove can reduce the effective contact area between the connecting nut and the inner wall of the pre-reserved connecting nut mounting groove on the prefabricated side plate b, thereby reducing the difficulty of rotating the connecting nut in the connecting nut mounting groove, and thus helping to improve the working efficiency of connecting or disassembling screw a and screw b.

A water-stop plate 2 and a positioning sleeve 3 are fitted on the outside of the screw a1. The positioning sleeve 3 is located between the water-stop plate 2 and the connecting nut 4. A washer pressure plate 6 and a locking nut 7 are installed on the outside of the screw b5. The washer pressure plate 6 is located between the connecting nut 4 and the locking nut 7. By vertically embedding the fixing plate 13 into the precast side plate a8, and attaching the reinforcing cage 10 to the side surface of the precast side plate a8 where the other end of the screw a1 extends, and then attaching the precast side plate b9 to the other side surface of the reinforcing cage 10, the end of the screw b5 is coaxially connected to the screw a1 through the connecting nut 4, and the washer plate 6 is pressed and fixed to the outer side surface of the precast side plate b9 using the locking nut 7, thereby pressing and connecting the precast side plate a8, precast side plate b9, and reinforcing cage 10 to form a precast side plate unit for the ultra-high prefabricated water tank. One end of the positioning sleeve 3 abuts against the waterstop plate 2, and the other end abuts against the precast side plate b9, so as to achieve precise control of the distance between the precast side plate a8 and the precast side plate b9, thereby ensuring that the thickness of the precast side plate unit of the ultra-high prefabricated water tank is uniform, and the screw b5 can be reused, thereby saving the construction cost of the ultra-high prefabricated water tank.
[0036] Furthermore, such as Figure 3 As shown, notches a21 are provided on the upper and lower sides of the waterstop plate 2, and eaves plates 22 are provided on the left and right sides of the waterstop plate 2. Notches b20 are provided on the eaves plates 22. Furthermore, the bending direction of the eaves plates 22 is consistent with the axial direction of the screw a1. Specifically, by providing notches a21 on the upper and lower sides of the waterstop plate 2, and providing eaves plates 22 on the left and right sides of the waterstop plate 2, with notches b20 on the eaves plates 22, the main function of the eaves plates 22, notches a21, and notches b20 is to effectively improve the interlocking force between the waterstop plate 2 and the concrete poured into the casting cavity inside the precast side plate unit, thereby effectively improving the overall robustness of the precast side plate unit of the ultra-high prefabricated water tank.
[0037] In this embodiment, a screw hole is provided on the waterstop plate 2, through which the screw rod a1 passes, and a hexagonal nut a23 corresponding to the screw hole is provided on the side of the waterstop plate 2. Specifically, the operator can use a wrench to hold the hexagonal nut a23 on the waterstop plate 2, thereby adjusting the position of the waterstop plate 2 on the screw rod a1, which improves the convenience of adjusting the waterstop plate 2.
[0038] In this embodiment, a threaded section 12 is formed on the surface of the screw a1, and a pre-embedded section 11 is installed on the outer surface of the threaded section 12. The waterstop plate 2 and the positioning sleeve 3 are both installed on the threaded section 12, and the fixing plate 13 is installed at the end of the pre-embedded section 11. Specifically, the main function of the pre-embedded section 11 is to insert the pre-embedded section 11 into the mold cavity when making the prefabricated side plate a8, thereby facilitating the control of the pre-embedded depth of the screw a1.
[0039] Furthermore, such as Figure 4 and Figure 5 As shown, the connecting nut 4 has internal threaded holes a43 and b44. The end of the threaded segment 12 is located in the internal threaded hole a43, and the end of the screw b5 is located in the internal threaded hole b44. The internal threaded holes a43 and b44 are connected. Furthermore, the diameter of the internal threaded hole a43 is larger than the diameter of the internal threaded hole b44.
[0040] In this embodiment, a hexagonal nut b41 corresponding coaxially to the internal threaded hole b44 is provided on the side of the connecting nut 4. Specifically, when using the connecting nut 4 to connect screw a1 and screw b5, a wrench can be used to hold the hexagonal nut b41 on the waterstop plate 2, thereby improving the clamping convenience of the connecting nut 4. Furthermore, an circumferential groove 42 is provided on the outer surface of the connecting nut 4. Specifically, by providing an circumferential groove 42 on the outer surface of the connecting nut 4, the circumferential groove 42 can reduce the effective contact area between the connecting nut 4 and the inner wall of the pre-reserved connecting nut mounting groove 91 on the prefabricated side plate b9, thereby reducing the difficulty of rotating the connecting nut 4 in the connecting nut mounting groove 91, and thus helping to improve the working efficiency of connecting the connecting nut 4 when connecting or disassembling screw a1 and screw b5.
[0041] The working process of this utility model is as follows: Figures 6-8 As shown, by vertically embedding the fixing plate 13 into the precast side plate a8, and attaching the reinforcing cage 10 to the side surface of the precast side plate a8 where the other end of the screw a1 extends, the worker uses a wrench to hold the hexagonal nut a23 on the waterstop plate 2, thereby adjusting the position of the waterstop plate 2 on the screw a1. Then, the precast side plate b9 is attached to the other side surface of the reinforcing cage 10, while one end of the positioning sleeve 3 abuts against the waterstop plate 2 and the other end abuts against the precast side plate b9, and the other end of the screw a1 is inserted into the pre-reserved mounting hole on the precast side plate b9. A connecting nut 4 is installed in the connecting nut mounting groove 91 on the outer side surface of the precast side plate b9, which corresponds one-to-one with the mounting hole. The connecting nut 4 is used to connect the end of the screw a1 located in the connecting nut mounting groove 91 to the screw. One end of rod b5 is fixedly connected together. The washer plate 6 is sleeved on the screw rod b5, and the washer plate 6 is pressed and fixed to the outer side of the precast side plate b9 using the locking nut 7. This makes the precast side plate a8, precast side plate b9 and steel cage 10 pressed and connected to form a precast side plate unit of the ultra-high prefabricated water tank. When the precast side plate unit of the ultra-high prefabricated water tank is assembled into a side plate of the ultra-high prefabricated water tank, concrete is poured into the casting cavity between the precast side plate a8 and the precast side plate b9, so that the precast side plate a8, precast side plate b9 and steel cage 10 are cast into one piece. After the concrete solidifies, the screw rod b5 and the connecting nut 4 can be disassembled and reused. Then, cement mortar is used to fill and smooth the connecting nut installation groove 91 on the precast side plate b9.
[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
