Description

Technical Field

[0001] This utility model relates to the field of waterproof construction technology, and in particular to a waterproof structure for the connecting joints of prefabricated culvert assemblies. Background Technology

[0002] Waterproof joint structures for culvert assembly are often manufactured in sections. These structures are then transported to the installation site, and the culverts are assembled to form a complete structure. Since culverts are buried deep underground for extended periods, waterproofing treatment is necessary at the joints. Traditional waterproofing involves adding waterproof sealing blocks at the joints of adjacent culverts, relying on the contact between the sealing blocks and the culverts to achieve waterproofing.

[0003] However, as the waterproof sealing blocks are buried underground for a long time and the sealing time is extended, they may gradually age, which will cause the elasticity of the sealing blocks to gradually decrease. This will cause gaps to form between the sealing blocks and the culvert cover, resulting in water leakage at the joints of the culvert.

[0004] Therefore, it is necessary to provide a new waterproof structure for the joints of prefabricated culvert assemblies to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a waterproof joint structure for the assembly of prefabricated culverts that avoids gaps between the sealing block and the culvert due to decreased elasticity caused by the aging of the sealing block after long-term use.

[0006] To solve the above-mentioned technical problems, the present utility model provides a prefabricated culvert assembly joint waterproof structure comprising: an inner corner plate, which is fixedly connected to the included angle on the inner side of the connection point between the vertical wall and the top plate by bolts; and a water-stopping structure, which is clamped between the connection node of the vertical wall and the top plate, the water-stopping structure comprising a water-stopping bladder, an inflation port, a waterproof membrane, a protective cover, a valve, and a sealing cap, wherein the water-stopping bladder is clamped between the connection node of the vertical wall and the top plate, and the waterproof membrane is fixed to both ends of the water-stopping bladder; and the protective cover... The valve is fixed inside both ends of the water-stop bladder, the air valve is fixed in the center of the protective cover, the air inlet is located at one end of the protective cover, and the sealing cap is threaded to the inner side wall of the protective cover; the fixing plate is fixed by bolts to the angle between the connection point of the vertical wall and the top plate, the fixing plate includes an outer corner plate and a protrusion, the outer corner plate is right-angled, and the outer corner plate is installed on the right-angle side of the top side wall of the vertical wall through the right-angle side, and the protrusion is fixed to the bottom surface of one end of the outer corner plate.

[0007] Preferably, the water-stopping bag is trapezoidal in shape and hollow inside, and the bottom sidewall of the top plate is provided with a bevel, and the sidewall of one end of the water-stopping bag is beveled, and the bevel of the water-stopping bag corresponds to the bevel of the sidewall of the top plate.

[0008] Preferably, the waterproof membrane is T-shaped and easily deformable, and the end of the waterproof membrane connected to the waterstop is clamped between the connection point of the vertical wall and the top plate.

[0009] Preferably, one end of the valve extends through one end of the water-stop bladder and connects to the internal space, and the connection point between the valve and the water-stop bladder is sealed, and the interior of the water-stop bladder is connected to the outside through the valve.

[0010] Preferably, the top plate has grooves at both ends of its surface, and the top surface of the vertical wall also has corresponding grooves, with the protrusions engaging inside the grooves.

[0011] Preferably, the waterproof membranes fixed at both ends of the water-stopping bladder have the same shape, and the widths of the two sets of waterproof membranes correspond to the lengths of the outer corner plate and the inner corner plate.

[0012] Preferably, the protective cover has a shape corresponding to the trapezoidal shape of the water-stopping bag, and the protective cover is supported inside both ends of the water-stopping bag.

[0013] Compared with related technologies, the waterproof joint structure for assembled culvert covers provided by this utility model has the following advantages:

[0014] This utility model provides a waterproof structure for the joint of a prefabricated culvert slab assembly. First, when erecting the top slab, the water-stop structure is placed in the mounting groove at the top of the vertical wall, with the right-angled edge of the water-stop bladder fitting against the right angle in the mounting groove. Then, the top slab is hoisted and erected. Before the top slab is inserted, the inner side of the waterproof membrane is folded outwards. When the top slab is inserted into the mounting groove at the top of the vertical wall, only the waterproof membrane connected to one end of the water-stop bladder is clamped, so that the waterproof membrane, clamped by the top slab, seals the gap between the top slab and the vertical wall. Then, the folded waterproof membrane is repositioned and laid on the outer wall of the connection node between the vertical wall and the top slab. Bolts are used to secure the inner waterproof membrane through the inner corner plate. Finally, the fixing plate abuts against the side wall of the outer waterproof membrane. The fixing plate compresses the waterproof membrane, inserting it into the groove and securing it with bolts. This allows the compressed waterproof membrane to adhere tightly to the top surface of the gap at the connection point between the wall and the roof, sealing the gap. An air pump connected to a valve then inflates the water-stop bladder, causing it to deform and fill the gap at the angle between the wall and the roof, further reinforcing the waterproof seal. The inflation port is then sealed with a cap, protecting the valve from damage and ensuring the water-stop bladder remains inflated. This prevents the water-stop bladder from shrinking and developing gaps due to aging and loss of elasticity. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 , Figure 1 A schematic diagram of a preferred embodiment of the waterproof joint structure for the assembly of prefabricated culvert covers provided by this utility model; Figure 2 for Figure 1 A three-dimensional structural diagram of the water-stopping structure shown. Figure 3 for Figure 2 The diagram shows the structure of the fixing plate. Figure 4 for Figure 1 A schematic diagram of a cross-section of one end of the water-stopping structure shown. Figure 5 for Figure 4 The diagram shows a three-dimensional view of the protective cover. The prefabricated culvert assembly joint waterproofing structure includes: an inner corner plate 1, which is bolted to the included angle between the connection point of the vertical wall 5 and the top plate 4; a water-stop structure 3, which is clamped between the connection node of the vertical wall 5 and the top plate 4. The water-stop structure 3 includes a water-stop bladder 31, an inflation port 32, a waterproof membrane 33, a protective cover 34, a valve 35, and a sealing cap 36. The water-stop bladder 31 is clamped between the connection node of the vertical wall 5 and the top plate 4, and the waterproof membrane 33 is fixed to both ends of the water-stop bladder 31. The protective cover 34... The valve 35 is fixed inside both ends of the water-stop bladder 31, and the air valve 35 is fixed in the center of the protective cover 34. The air inlet 32 ​​is located at one end of the protective cover 34, and the sealing cover 36 is threaded to the inner side wall of the protective cover 34. The fixing plate 2 is fixed by bolts to the angle outside the connection point between the vertical wall 5 and the top plate 4. The fixing plate 2 includes an outer corner plate 21 and a protrusion 22. The outer corner plate 21 is right-angled and is installed on the right-angle side of the top side wall of the vertical wall 5. The protrusion 22 is fixed to the bottom surface of one end of the outer corner plate 21.

[0023] In the specific implementation process, such as Figure 1 , Figure 2 and Figure 5As shown, the water-stop bladder 31 is trapezoidal in shape and hollow inside. The bottom sidewall of the top plate 4 has a beveled edge, and one end of the water-stop bladder 31 has a beveled edge, which corresponds to the beveled edge of the top plate 4. The protective cover has a shape corresponding to the trapezoidal shape of the water-stop bladder 31, and the protective cover 34 is supported inside both ends of the water-stop bladder 31. This allows the protective cover to support the water-stop bladder and maintain its trapezoidal shape when the top plate 4 is installed, so that the side of the water-stop bladder 31 can correspond to the beveled edge of the top plate 4, and the water-stop bladder 31 can fit the gap between the top plate 4 and the vertical wall 5, thereby effectively preventing damage to the water-stop bladder 31 when the cover plate is installed.

[0024] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the waterproof membrane 33 is T-shaped and easily deformable. One end of the waterproof membrane 33 connected to the water-stop bladder 31 is clamped between the connection point of the vertical wall 5 and the top plate 4. This allows the waterproof membrane 33 to seal the gap between the vertical wall 5 and the top plate 4. At the same time, the extended planar surface of the waterproof membrane 33 can be laid around the connection gap between the vertical wall 5 and the top plate 4 to enhance the water-stopping effect of the gap.

[0025] In the specific implementation process, such as Figure 1 and Figure 4 As shown, one end of the valve 35 passes through one end of the water-stop bladder 31 and connects to the internal space, and the connection point between the valve 35 and the water-stop bladder 31 is in a sealed state, and the interior of the water-stop bladder 31 is connected to the outside through the valve 35; this allows the internal space of the water-stop bladder 31 to be inflated or deflated through the valve 35, thereby causing the water-stop bladder 31 to deform.

[0026] In the specific implementation process, such as Figure 1 and Figure 3 As shown, the edges at both ends of the surface of the top plate 4 are provided with grooves, and the top surface of the vertical wall 5 is also provided with corresponding grooves, and the protrusion 22 is engaged inside the groove; the waterproof membrane 33 fixed at both ends of the water-stop bag 31 has the same shape, and the width of the two sets of waterproof membrane 33 corresponds to the length of the outer corner plate 21 and the inner corner plate 1; this facilitates the protrusion 22 to cooperate with the groove, squeezing and engaging the laid waterproof membrane 33 inside the groove, thereby restricting the position of the laid waterproof membrane 33, and at the same time restricting the deformation of the waterproof membrane 33, so that the waterproof membrane 33 fits more closely to the surface of the top plate 4 and the vertical wall 5.

[0027] The working principle of the prefabricated culvert assembly joint waterproof structure provided by this utility model is as follows:

[0028] When installing the top plate 4, first place the waterstop in the slot at the top of the vertical wall 5, so that the right-angled side of the waterstop 31 is aligned with the right-angled side of the slot in the vertical wall 5, and the two side surfaces of the waterstop 31 are flush with the side surfaces of the vertical wall 5. Then, hoist the top plate 4 onto the vertical wall 5. Before the top plate 4 is inserted into the slot, manually bend one end of the waterstop so that when the top plate 4 is inserted into the top of the vertical wall 5, the waterproof membrane connecting one end of the waterstop 31 is only clamped between the connection node of the top plate 4 and the vertical wall 5. 33. Simultaneously, the water-stopping bag 31 is clamped at the angle between the vertical wall 5 and the top plate 4. Then, the manually deformed waterproof membrane 33 is released, allowing it to be laid on the side wall surrounding the connection node between the top plate 4 and the vertical wall 5. Then, the outer wall of the inner corner plate 1 abuts against the angle between the inner connection node of the vertical wall 5 and the top plate 4, clamping the waterproof membrane 33 against the wall. Then, it is fixed to the inner side wall of the vertical wall 5 and the top plate 4 with bolts to fix the position of the inner waterproof membrane 33. Then, the outer corner plate 21 is clipped onto the wall. On the side wall of the connection node between the vertical wall 5 and the outer side of the top plate 4, the protrusion 22 is used to press the laid waterproof membrane 33 into the groove, so that the middle section of the pressed waterproof membrane 33 can tightly abut against the connection node between the vertical wall 5 and the top plate 4. Then, it is fixed with bolts, so that the waterproof membrane 33 becomes the first waterproof layer around the connection node between the vertical wall 5 and the top plate 4. Then, using an air tool, it is connected to one end of the air valve 35 through the air inlet 32, and then the water stop bag 3 is injected through the air valve 35. The interior of the water-stop bladder 31 is inflated with gas. As the gas enters, the water-stop bladder 31 expands, causing it to deform and thus sealing the gap between the vertical wall 5 and the top plate 4, achieving a waterproof effect. Then, the air inlet 32 ​​is sealed by the sealing cover 36, and the air valve 35 is protected inside the protective cover 34, ensuring that the interior of the water-stop bladder 31 is always filled with gas and remains in an expanded state. This prevents the water-stop bladder 31 from shrinking and developing gaps due to decreased elasticity caused by aging.

[0029] Compared with related technologies, the waterproof joint structure for assembled culvert covers provided by this utility model has the following advantages:

[0030] This utility model provides a waterproof structure for the joint of a prefabricated culvert slab assembly. First, when erecting the top slab, the water-stop structure is placed in the mounting groove at the top of the vertical wall, with the right-angled edge of the water-stop bladder fitting against the right angle in the mounting groove. Then, the top slab is hoisted and erected. Before the top slab is inserted, the inner side of the waterproof membrane is folded outwards. When the top slab is inserted into the mounting groove at the top of the vertical wall, only the waterproof membrane connected to one end of the water-stop bladder is clamped, so that the waterproof membrane, clamped by the top slab, seals the gap between the top slab and the vertical wall. Then, the folded waterproof membrane is repositioned and laid on the outer wall of the connection node between the vertical wall and the top slab. Bolts are used to secure the inner waterproof membrane through the inner corner plate. Finally, the fixing plate abuts against the side wall of the outer waterproof membrane. The fixing plate compresses the waterproof membrane, inserting it into the groove and securing it with bolts. This allows the compressed waterproof membrane to adhere tightly to the top surface of the gap at the connection point between the wall and the roof, sealing the gap. An air pump connected to a valve then inflates the water-stop bladder, causing it to deform and fill the gap at the angle between the wall and the roof, further reinforcing the waterproof seal. The inflation port is then sealed with a cap, protecting the valve from damage and ensuring the water-stop bladder remains inflated. This prevents the water-stop bladder from shrinking and developing gaps due to aging and loss of elasticity.
