Description
Technical Field
[0001] The utility model belongs to the technical field of building water conservancy dredging, and particularly relates to a hydrophobic joint for expansion joints on a wet working ground. Background Art
[0002] In workplaces such as large factories and workshops, expansion joints need to be reserved after the ground is hardened to meet the requirements of ground thermal expansion and contraction and prevent the ground from arching and cracking. For a clean workshop, the floor of the rough workshop is obviously not directly applicable. Therefore, secondary treatment of the ground is required to improve the flatness, cleanliness, etc. of the ground. For example, in a food production workshop, secondary pouring is required on the original rough concrete ground, such as a self-leveling cement floor. At this time, in order to ensure that the secondary-poured ground still has the ability to adapt to thermal expansion and contraction, users usually set expansion joints on the secondary-poured ground as well, and the expansion joints of the secondary pouring are vertically connected to the expansion joints of the rough ground, so as to avoid the occurrence of layer fault phenomenon between the two layers of the ground due to the misalignment of the expansion joints, resulting in the shelling and separation of the secondary-poured ground from the rough ground and affecting the strength of the secondary-poured ground.
[0003] For workshops with a relatively humid production environment, such as food processing workshops, aquaculture workshops, precision parts cleaning workshops, etc., the workshop floor is prone to water accumulation and operation residues, which are likely to cause blockage of the expansion joints. In the long run, the expansion joints will lose the ability to absorb ground expansion, resulting in the ground being squeezed and arched during expansion and causing ground damage. Therefore, it is necessary to provide a hydrophobic joint for ground expansion joints to solve the above technical problems. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a hydrophobic joint for expansion joints on a wet working ground, so as to solve the technical problem that operation dust and operation residues on the wet working ground are washed into the expansion joints by sewage, resulting in the loss of function of the expansion joints.
[0005] To solve the above technical problem, the technical solution adopted by the utility model is: a hydrophobic joint for expansion joints on a wet working ground, including a groove body extending along the axial direction of the expansion joint, lining plates respectively connected to the upper edges on both sides of the groove body, and a panel covering the upper surfaces of the groove body and the lining plates. One end of the panel is detachably and fixedly connected to the lining plate on one side of the groove body, and the other end of the panel is movably abutted against the lining plate on the other side of the groove body. The lining plates are used to connect the ground on both sides of the expansion joint. Positioning strips are respectively connected to the mutually remote sides of the two lining plates. Any one of the positioning strips extends along the axial direction of the expansion joint. The panel is arranged between the two positioning strips. A telescopic gap is left between the end of the panel movably abutted against the lining plate and the adjacent positioning strip. The positioning strips are embedded in the ground, and the top surface of the positioning strips is not higher than the ground.
[0006] As a preferred solution, the positioning strip is a strip, a pipe fitting or an inverted groove-shaped structure, and the positioning strip is connected by a connecting piece, directly welded or integrally formed on the lining plate; the connecting piece is any one of a bolt, a clamping piece, a rivet and a magnet.
[0007] As a preferred solution, when the positioning strip and the lining plate are integrally formed, at least the edge of the lining plate is bent vertically upward in sequence to form a vertical edge, bent vertically away from the panel to form a top edge, and bent downward to form an inclined or vertical flanging.
[0008] As a preferred solution, when the positioning strip is connected or welded to the lining plate by a connecting piece, a plugging plate extending obliquely downward or vertically downward is welded or integrally formed on the edge of the side of the lining plate away from the trough body, and a plurality of through holes arranged discretely along the axial direction of the trough body are formed in the plugging plate.
[0009] As a preferred solution, the surface of the panel facing the lining plate is a rough surface, and a flow channel for water to flow through is provided between the panel and the lining plate.
[0010] As a preferred solution, a baffle is respectively connected to the bottom surfaces of the two lining plates, the distance between the two baffles is greater than the width of the expansion joint on the blank ground, and the two baffles respectively extend along the axial direction of the trough body.
[0011] As a preferred solution, a drain pipe is connected to the bottom of the trough body, the drain pipe is communicated with the inside of the trough body, and both ends of the trough body are sealed.
[0012] As a preferred solution, the end face of the trough body is one of a "V" shape, a "U" shape, a "W" shape and an inverted "Ω" shape.
[0013] As a preferred solution, the panel is detachably connected to the corresponding lining plate by bolts. A counterbore is provided on the panel, a nut is welded to the bottom surface of the lining plate, the lower end of the nut is a closed end, and the bolt passes through the counterbore on the panel and the lining plate and is threadedly connected to the nut.
[0014] As a preferred solution, the expansion gaps are arranged in a serpentine pattern.
[0015] The beneficial effects of the present utility model are as follows: The present utility model uses the lining plate and the trough body to connect the ground on both sides of the expansion joint, so that the sewage on the ground is discharged through the trough body, avoiding the problems that sewage enters the expansion joint and causes difficult cleaning and disfunction. At the same time, the present utility model covers the trough body with a panel above the lining plate to avoid the safety hazard caused by the exposure of the trough body. Since the panel and the lining plate are not sealed, the sewage can flow into the trough body through the gap between the panel and the lining plate. The size of the gap between the panel and the lining plate can be adjusted according to the user's needs to achieve the filtering effect on the dirt in the ground sewage. The panel with a one-sided detachable connection can be disassembled at any time to clean the surface of the lining plate and the inside of the trough body, improving the convenience of cleaning.

[0028] The following describes in detail the specific implementation schemes of the present utility model in conjunction with the accompanying drawings. Embodiment 1
[0029] As Figures 1 to 3The described moisture-proof expansion joint hydrophobic joint for a wet working floor includes a trough body 2 extending axially along the expansion joint 1, lining plates 3 respectively connected to the upper edges on both sides of the trough body 2, and a panel 4 covering the upper surfaces of the trough body 2 and the lining plates 3. One end of the panel 4 is detachably and fixedly connected to the lining plate 3 on one side of the trough body 2 through a bolt 13, and the other end of the panel 4 is non-sealingly and movably abutted against the lining plate 3 on the other side of the trough body 2. The two lining plates 3 are respectively used to connect the floors on both sides of the expansion joint 1. Positioning strips 5 are respectively connected to the mutually remote sides of the two lining plates 3. The outer sides of the two positioning strips 5 are in contact with the floor. Any one of the positioning strips 5 extends axially along the expansion joint 1. The panel 4 is arranged between the two positioning strips 5. There is an expansion gap 6 between the end of the panel 4 movably abutted against the lining plate 3 and the adjacent positioning strip 5. The positioning strip 5 is embedded in the floor, and the top surface of the positioning strip 5 is not higher than the floor surface.
[0030] In this embodiment, the positioning strip 5 is preferably a strip with the same thickness as the panel 4. The positioning strip 5 is connected to the lining plate 3 through a connecting member 7, and the connecting member 7 also uses a bolt. In practical applications, the positioning strip 5 can also be directly connected to the upper surface or edge of the lining plate 3 by welding.
[0031] In this embodiment, there is a planar gap or strip-shaped or mesh-shaped flow channels 10 between the abutting surfaces of the panel 4 and the lining plate 3 in movable abutment, for sewage to flow from between the panel 4 and the lining plate 3 into the trough body 2. The planar gap refers to a large planar area gap between the panel 4 and the lining plate 3. These gaps can be formed by the rough and uneven bottom surface of the panel 4 or the uneven surface of the lining plate 3. The strip-shaped or mesh-shaped flow channels are strip-shaped or mesh-shaped grooves pre-processed on the bottom surface of the panel 4. The grooves communicate with each other and communicate with the expansion gap 6 and the trough body 2.
[0032] As Figure 9 illustrates a shape of the grooves on the bottom surface of the panel 4 that can form the mesh-shaped flow channels 10. In practical applications, the shapes of the grooves that can form the flow channels 10 are diverse, and this embodiment does not list them one by one.
[0033] The sewage in the trough body 2 can be discharged through an external discharge pipeline provided at the end of the trough body 2, or can also be externally discharged through a drain pipe connected to the bottom of the trough body 2. In this embodiment, it is preferably discharged through the external discharge pipeline at the end of the trough body 2. The external discharge pipeline can be preset in the wall body, thereby simplifying the structure and assembly difficulty of this embodiment.
[0034] In practical applications, the positioning strip can also be a square pipe or an inverted channel steel, as Figure 5 shown. The groove formed between the two positioning strips is preferably not less than the thickness of the panel to avoid tripping over the protruding panel.
[0035] In order to make the panel 4 detachable, in this embodiment, the nut cooperating with the bolt 13 is fixedly welded to the bottom surface of the lining plate 3, and the lower end of the nut 14 is a closed end. The bolt 13 passes through the counterbore on the panel 4 and the lining plate 3 and is threadedly connected to the nut 14. In this way, the bolt will not be stuck by the poured ground, resulting in the inability to disassemble and clean the panel 4.
[0036] In this embodiment, the end face of the trough body 2 is preferably in a "V" shape. In practical applications, the end face of the trough body 2 can also be in a "U" shape, a "W" shape, an inverted "Ω" shape. Any trough body 2 with an upper opening and an elastic shrinkable opening end can be used, and in practical applications, the "V"-shaped trough body 2 has a better effect.
[0037] The working process of this embodiment is as follows: As Figure 3 shown, when the wet working ground expansion joint hydrophobic joint of this embodiment is in use, there are two cases. One is to assemble on the already formed ground. At this time, it is necessary to remove the surface layer of the ground on both sides of the expansion joint 1, and then embed the lining plate 3 and the positioning strip 5 into the ground, and make the trough body 2 embed into the expansion joint 1. Then fixedly connect the lining plate 3 or the positioning strip 5 to the ground below, so that the lining plate 3 or the positioning strip 5 is firmly connected to the ground. The other is to preset the wet working ground expansion joint hydrophobic joint at the designed position before pouring the ground, and then pour the ground. The wet working ground expansion joint hydrophobic joint can be preset by means of bottom support or top suspension.
[0038] When the ground on both sides of the expansion joint 1 expands, the ground will push the two positioning strips 5 and the lining plate 3 to squeeze towards the trough body 2, and the upper opening of the trough body 2 shrinks to absorb the expansion of the ground, and the expansion gap 6 shrinks. When the ground shrinks, the ground on both sides of the expansion joint 1 respectively pulls the connected positioning strip 5 or the lining plate 3 to move away from each other, and the upper opening of the trough body 2 expands to compensate for the shrinkage of the ground, and the expansion gap 6 expands.
[0039] The accumulated water on the ground flows into the trough body 2 through the flow channel 10 between the panel 4 and the lining plate 3 through the expansion gap 6. The sewage in the trough body 2 can be discharged outward through the drainage pipes preset on the two end walls of the trough body 2, or discharged outward through the drain pipe 12 connected to the bottom of the trough body 2.
[0040] After using for a period of time, the user can remove the panel 4 and wash the bottom surface of the panel 4, the surface of the lining plate 3 and the inside of the trough body 2 to keep the flow channel 10 unobstructed. Embodiment 2
[0041] As Figure 4The following shows a further improvement to the hydrophobic joint for the expansion joint of the wet working floor mentioned above. In order to adapt to the secondary pouring of the rough floor, in this embodiment, a baffle 11 is further connected to the bottom surfaces of the two lining plates 3 respectively. The distance between the two baffles 11 is greater than the width of the expansion joint 1 on the rough floor, and the two baffles 11 extend along the axial direction of the trough body 2 respectively. The two baffles 11 are used to block the fluid from flowing into the expansion joint 1 of the rough floor during secondary pouring, and are also used to support the lining plate 3 and the trough body 2. An expansion joint for the secondary pouring floor is formed between the two baffles 11.
[0042] In order to improve the connection strength between the lining plate 3 and the ground, in this embodiment, it is also preferably welded or integrally formed with an insertion plate 8 that extends obliquely downward on the side edge of the lining plate 3 away from the trough body 2. A plurality of through holes 9 are arranged in a discrete manner along the axial direction of the trough body 2 on the insertion plate 8.
[0043] In practical applications, the insertion plate 8 can also extend vertically downward, pass through the through holes 9 during the secondary ground pouring, and firmly fix the insertion plate 8 and the lining plate 3 on the ground after curing.
[0044] The working process of this embodiment is as follows: As Figure 4 shown, before the secondary pouring of the rough floor, place the hydrophobic joint for the expansion joint of the wet working floor described in this embodiment on the rough floor, so that the two baffles 11 are respectively arranged on both sides of the expansion joint 1 of the rough floor, and then carry out the secondary pouring of the ground. Pour the pouring material until its upper surface is flush with the upper surface of the positioning strip 5, and directly pour the hydrophobic joint for the expansion joint of the wet working floor into the secondary pouring floor.
[0045] After the secondary poured ground is cured, when the ground on both sides of the expansion joint 1 expands, it will simultaneously push the lining plate 3, the positioning strip 5, the insertion plate 8 and the baffle 11, increasing the ground stress area and avoiding damage to the ground caused by the reaction force of the hydrophobic joint for the expansion joint of the wet working floor.
[0046] The principle of the hydrophobic joint for the expansion joint of the wet working floor to absorb and compensate for the thermal expansion and contraction of the ground is the same as that of Embodiment 1. Embodiment 3
[0047] Based on Embodiment 1 or 2, the hydrophobic joint for the expansion joint of the wet working floor described in this embodiment has improved the structure of the positioning strip 5. In this embodiment, the positioning strip 5 is connected to the lining plate 3 by welding or integrally formed with the lining plate 3.
[0048] As Figure 6 shown, the positioning strip 5 in this embodiment is formed by bending the edge of the lining plate 3. The edge of the lining plate 3 is successively bent vertically upward to form a vertical side 5a, then bent vertically away from the panel 4 to form a top side 5b, and then bent downward to form an inclined or vertical flanging 5c.
[0049] In practical applications, the positioning strip 5 can also be formed by bending a sheet and then welding it to the edge of the lining plate 3.
[0050] Using the positioning strip 5 integrally formed with the lining plate 3 can avoid the step of connecting the positioning strip 5 and the lining plate 3 with a connecting piece 7, simplify the assembly steps, improve production efficiency, and reduce production costs.
[0051] In practical applications, the positioning strip 5 formed by bending the edge of the lining plate 3 can also be in Figure 7 various shapes as shown. In essence, any shape that can block the ground on both sides, form a sealing edge for the ground, and jointly form the shape of the expansion gap with the panel 4 can be used as the positioning strip 5, and users can further select according to the actual use effect.
[0052] In practical applications, users can also design the structures of the two positioning strips 5 differently according to needs. For example, one positioning strip adopts the structure of the positioning strip in Embodiment 1, and the other positioning strip adopts the bending structure described in this embodiment. Since this differential design can be obtained by combining Embodiment 1 and Embodiment 3, no additional drawings are shown in this embodiment. Embodiment 4
[0053] Based on Embodiment 2, the two ends of the trough body 2 of the hydrophobic joint for the expansion joint of the wet working ground described in this embodiment are sealed. Combining Figure 4 and Figure 8 , when a drain pipe 12 is connected to the bottom of the trough body 2, to prevent the sewage inside the trough body 2 from seeping out through the two end walls, the two ends of the trough body 2 are sealed in this embodiment, and a sealing plate 15 is welded to each of the two ends of the trough body 2. To reduce the negative effect of the sealing plate 15 on the absorption of ground expansion by the trough body 2, the sealing plate in this embodiment is preferably designed to be concave in the middle towards the inside of the trough body 2.
[0054] In practical applications, the sealing plate 15 can also be a straight plate or a silicone sheet. When a silicone sheet is used as the sealing plate 15, the sealing plate 15 is bonded to the trough body 2.
[0055] To further overcome the problem that sewage may seep to the side of the sealing plate 15 facing away from the trough body 2 at the top of the sealing plate 15 with a concave middle, resulting in sewage leakage, a sealing gasket 16 is further provided at the position of the panel 4 corresponding to the sealing plate 15 in this embodiment, and the connection between the panel 4 and the top of the sealing plate 15 is sealed by the sealing gasket 15, so that sewage cannot leak through the outside of the sealing plate 15.
[0056] In practical applications, even if a straight plate is used as the sealing plate 15, since the thermal expansion range is reduced by the influence of the wall at the connection between the ground and the wall, the sealing plate 15 will not be squeezed and deformed too much, and the straight plate used as the sealing plate 15 has a small influence on the expansion of the expansion joint.
[0057] The working process of this embodiment is similar to that of Embodiment 2, and will not be elaborated here. Embodiment 5
[0058] On the basis of Embodiment 1, the wet working floor expansion joint hydrophobic joint described in this embodiment improves the specific structure of the expansion gap 6. As Figure 10 shown, the expansion gap 6 in this embodiment is arranged in a serpentine shape. Compared with the linear expansion gap 6, such an expansion gap 6 has higher safety and is not easy to trip over. Therefore, the width of the expansion gap 6 can be appropriately increased, so as to expand the expansion range of the wet working floor expansion joint hydrophobic joint and improve the applicable range.
[0059] The above embodiments only illustratively explain the principle and efficacy of the present invention and some applied embodiments, rather than limiting the present invention; it should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
