[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.
[0028] The gutter unit of the embodiment of the utility model comprises a first gutter 1, a second gutter 2 and a lap assembly 3. The first gutter 1 and the second gutter 2 are arranged in the extension direction of the first gutter 1 (such as Figure 1 The overlapping assembly 3 includes a first baffle plate 31, a second baffle plate 32 and an overlapping component 33. The first baffle plate 31 is arranged at one end of the first gutter 1 adjacent to the second gutter 2. The second baffle plate 32 is arranged at one end of the second gutter 2 adjacent to the first gutter 1. One end of the overlapping component 33 is connected to the first baffle plate 31, and the other end of the overlapping component 33 is overlapped on the second baffle plate 32 and the second gutter 2.
[0029] Specifically, if Figure 1-Figure 5As shown, the first and second gutters 1 and 2 are located at both ends of the expansion joint 100 in the width direction, the expansion joint 100 extends in the front-to-back direction, the first gutters 1 are located on the left side of the expansion joint 100, and the second gutters 2 are located on the right side of the expansion joint 100. The first and second gutters 1 and 2 each include a bottom wall, a side wall, and an edge, the bottom wall extends in the left-right direction, the side wall extends in the up-down direction, the front and rear ends of the bottom wall are respectively connected to the lower ends of the two side walls, the bottom wall and the side wall are connected to form a water collecting groove, the side wall extends in a direction away from the water collecting groove to form an edge, and the bottom wall, the side wall, and the edge can be integrally formed.
[0030] The first baffle plate 31 is connected to the right end of the first groove 1, the second baffle plate 32 is connected to the left end of the second groove 2, the left end of the overlapping component 33 is connected to the first baffle plate 31, the right end of the overlapping component 33 is overlapped on the edge of the second baffle plate 32 and the second groove 2, and the right lower end surface of the overlapping component 33 is in contact with the upper end surface of the edge of the second baffle plate 32 and the second groove 2, that is, the right side of the overlapping component 33 is overlapped on the second baffle plate 32 and the second groove 2, so that when the first groove 1 and the second groove 2 are close to or away from each other, the overlapping position of the overlapping component 33 will change accordingly to prevent the first groove 1 and the second groove 2 from being stretched.
[0031] Compared with the welding connection between the first gutter 1 and the second gutter 2 on both sides of the expansion joint 100 in the related art, the first gutter 1 and the second gutter 2 will be stretched synchronously when the building expands and contracts, resulting in the first gutter 1 and the second gutter 2 being angular. The gutter unit of the utility model embodiment is connected to the first baffle 31 through the left end of the overlapping part 33, and the right end of the overlapping part 33 is overlapped on the second baffle 32 and the second gutter 2, that is, the left end of the overlapping part 33 is fixedly connected to the first gutter 1, and the right end of the overlapping part 33 is movably contacted and connected with the second gutter 2, so that when the width of the expansion joint 100 increases or decreases, the right end of the overlapping part 33 moves in the left and right directions to adapt to the changes of the expansion joint 100, avoiding the first gutter 1 and the second gutter 2 from being stretched, and ensuring the drainage performance of the gutter unit.
[0032] In some embodiments, the first baffle 31 is disposed along the width direction of the first gutter 1 (eg Figure 1 The first baffle 31 is connected to the sidewalls of the first groove 1 at both ends of the width direction of the first groove 1, and the first baffle 31 is connected to the sidewalls of the first groove 1 at both ends of the width direction of the first groove 1. Figure 1 One end of the first baffle plate 31 in the up-down direction as shown in the figure is connected to the bottom wall of the first groove 1, and the other end of the first baffle plate 31 in the height direction of the first groove 1 is connected to the overlapping part 33.
[0033] Specifically, Figure 2As shown, the lower end of the first baffle plate 31 is sealed to the bottom wall of the first gutter 1, and the front and rear ends of the first baffle plate 31 are respectively sealed to the side walls of the first gutter 1. The first baffle plate 31 blocks the right end of the first gutter 1 to prevent the water in the first gutter 1 from flowing into the expansion joint 100 while satisfying the water storage function of the first gutter 1.
[0034] For example, the first baffle 31 and the first gutter 1 may be welded by argon arc welding.
[0035] In some embodiments, the second baffle 32 extends along the width direction of the first groove 1, and the two ends of the second baffle 32 in the width direction of the first groove 1 are respectively connected to the side walls of the second groove 2, and one end of the second baffle 32 in the height direction of the first groove 1 is connected to the bottom wall of the second groove 2, and the overlapping part 33 is overlapped on the other end of the second baffle 32 in the height direction of the first groove 1.
[0036] Specifically, Figure 2 As shown, the lower end of the second baffle plate 32 is sealed to the bottom wall of the second gutter 2, and the front and rear ends of the second baffle plate 32 are respectively sealed to the side walls of the second gutter 2. The second baffle plate 32 blocks the left end of the second gutter 2 to prevent the water in the second gutter 2 from flowing into the expansion joint 100 while satisfying the water storage function of the second gutter 2.
[0037] For example, the second baffle 32 and the second groove 2 may be welded by argon arc welding.
[0038] In some embodiments, the overlapping component 33 includes a first overlapping piece 331, one end of the first overlapping piece 331 in the extension direction of the first groove 1 is connected to the other end of the first baffle plate 31 in the height direction of the first groove 1, and the other end of the first overlapping piece 331 in the extension direction of the first groove 1 is overlapped on the second baffle plate 32.
[0039] Specifically, Figure 2 As shown, the first lap joint 331 is plate-shaped, and the thickness direction of the first lap joint 331 is the up-down direction. The left end of the first lap joint 331 is sealed and connected to the upper end of the first baffle 31, and the right end of the first lap joint 331 is overlapped on the upper end of the second baffle 32, that is, the right lower end surface of the first lap joint 331 is in contact with the upper end surface of the second baffle 32, so that when the expansion and contraction of the building drives the interval distance between the first gutter 1 and the second gutter 2 to change, the contact position of the first lap joint 331 and the second baffle 32 moves synchronously to prevent the first gutter 1 and the second gutter 2 from being stretched.
[0040] For example, when the building undergoes thermal expansion, the width of the expansion joint 100 decreases, the spacing between the first gutter 1 and the second gutter 2 decreases, and the contact position between the right end of the first lap joint 331 and the second baffle 32 moves to the left. When the building undergoes cold contraction, the width of the expansion joint 100 increases, the spacing between the first gutter 1 and the second gutter 2 increases, and the contact position between the right end of the first lap joint 331 and the second baffle 32 moves to the right.
[0041] For example, the first bridging member 331 and the first baffle plate 31 are welded, or the first bridging member 331 and the first baffle plate 31 may be integrally formed.
[0042] For example, the initial size of the expansion joint 100 in the left-right direction is 200 mm, the expansion amount of the expansion joint 100 is 200 mm, and the size of the first bridging member 331 in the left-right direction is 400 mm, ensuring that the first bridging member 331 can have a movement amount of 200 mm in the left-right direction.
[0043] In some embodiments, the overlapping component 33 further includes a second overlapping piece 332 , which is connected to the first overlapping piece 331 at one end in the height direction of the first groove 1 , and overlaps the edge of the second groove 2 at the other end in the height direction of the first groove 1 .
[0044] Specifically, Figure 2 As shown, the second lap joint 332 includes a connecting section 3321 and an overlapping section 3322, both of which are plate-shaped, the connecting section 3321 extends in the up-down direction, and the overlapping section 3322 extends in the front-back direction, the lower end of the connecting section 3321 is connected to the upper end of the first lap joint 331, and the upper end of the connecting section 3321 is connected to the front end of the overlapping section 3322. The setting of the connecting section 3321 and the overlapping section 3322 facilitates overlapping on the edge of the second drain 2.
[0045] Optionally, in the embodiment of the utility model, the first joint 331 blocks the expansion joint 100, and the second joint 332 is connected to the first joint 331 to block the gap between the first joint 331 and the first and second gutters 1 and 2, thereby preventing rainwater from flowing into the expansion joint 100 along the gap between the first joint 331 and the first and second gutters 1 and 2.
[0046] It can be understood that the overlap in this embodiment means that the second overlap member 332 overlaps the edge of the second groove 2, and the second overlap member 332 only contacts the second groove 2. When the building expands or contracts, the movement of the first groove 1 and / or the second groove 2 can drive the contact point to move.
[0047] For example, the left end of the second bridging member 332 is welded to the first groove 1 .
[0048] In some embodiments, there are two second joints 332, and the two second joints 332 are arranged opposite to each other in the width direction of the first groove 1, and one of the second joints 332 is connected to one end of the first joint 331 in the width direction of the first groove 1, and the other second joint 332 is connected to the other end of the first joint 331 in the width direction of the first groove 1.
[0049] Specifically, Figure 2 As shown, the two second lap joints 332 are arranged at intervals in the front-to-back direction, and the second lap joint 332 located at the front end is connected to the front end of the first lap joint 331, and the second lap joint 332 located at the rear end is connected to the rear end of the first lap joint 331. The setting of the two second lap joints 332 can improve the overlapping stability of the overlapping component 33.
[0050] In some embodiments, the dimension of the second bridging member 332 in the extending direction of the first groove 1 is the same as the dimension of the first bridging member 331 in the extending direction of the first groove 1 .
[0051] Specifically, the size of the second bridging member 332 in the left-right direction is the same as that of the first bridging member 331 in the left-right direction, so as to ensure that when the bridging member 33 is displaced, the first bridging member 331 and the second bridging member 332 always shield the expansion joint 100 .
[0052] The connecting section 3321 and the overlapping section 3322 have the same size in the left-right direction, and the overlapping section 3322 has a size greater than or equal to the size of the edge of the second groove 2 in the front-back direction, so that the second connecting piece 332 can be overlapped on the second groove 2.
[0053] In some embodiments, the bridging component 33 also includes a third bridging piece 333, one end of the third bridging piece 333 in the height direction of the first groove 1 is connected to the other end of the second bridging piece 332 in the extension direction of the first groove 1, and the third bridging piece 333 extends toward the direction close to the bottom wall of the first groove 1.
[0054] Specifically, the upper end of the third bridging member 333 is connected to the right end of the second bridging member 332 , and the third bridging member 333 extends downward to prevent rainwater from flowing toward the expansion joint 100 along the gap between the third bridging member 333 and the first bridging member 331 .
[0055] For example, the dimension of the third bridging piece 333 in the vertical direction is 200 mm, and the angle between the third bridging piece 333 and the first bridging piece 331 is 90 degrees.
[0056] In some embodiments, the first baffle 31 and the second baffle 32 have the same size in the height direction of the first groove 1 , and the size of the first baffle 31 in the height direction of the first groove 1 is smaller than the size of the side wall of the first groove 1 in the height direction of the first groove 1 .
[0057] Specifically, the first baffle plate 31 and the second baffle plate 32 have the same size in the up-down direction, so that the first bridging piece 331 can be overlapped on the second baffle plate 32 .
[0058] The size of the first baffle plate 31 in the vertical direction is smaller than the size of the side wall of the first ditch 1 in the vertical direction, which is convenient for the installation of the overlapping component 33. It can be understood that the size of the first baffle plate 31 in the vertical direction can be specifically set according to the maximum water volume during actual project implementation.
[0059] For example, the dimensions of the first baffle plate 31 and the second baffle plate 32 in the up-down direction, that is, the heights of the first baffle plate 31 and the second baffle plate 32 are 450 mm.
[0060] The gutter drainage system of the embodiment of the utility model includes a gutter unit using any one of the above embodiments.
[0061] Specifically, the gutter row system of the embodiment of the utility model includes a gutter unit, which is connected to the first baffle 31 through the left end of the overlapping part 33, and the right end of the overlapping part 33 is overlapped on the second baffle 32 and the second gutter 2, that is, the left end of the overlapping part 33 is fixedly connected to the first gutter 1, and the right end of the overlapping part 33 is movably contacted and connected to the second gutter 2, so that when the width of the expansion joint 100 increases or decreases, the right end of the overlapping part 33 moves in the left and right directions to adapt to the changes of the expansion joint 100, thereby avoiding the first gutter 1 and the second gutter 2 from being stretched, ensuring the drainage performance of the gutter unit, and then ensuring the drainage performance of the gutter row system.
