Description

Technical Field

[0001] The present application relates to the technical field of expansion joint waterproofing, and in particular to an expansion joint waterproofing structure for building construction. Background Art

[0002] An expansion joint refers to a structural joint set at an appropriate position along the construction joint direction of a building or structure to prevent cracks or damage to the structure due to climate temperature changes (thermal expansion and contraction). The building or structure can expand and contract horizontally along its length.

[0003] In concrete buildings, waterproof structures need to be installed at expansion joints to prevent quality problems such as leakage and seepage.

[0004] Currently, most of the existing expansion joint waterproof structures are of fixed width, and the width of the expansion joint needs to be determined according to the actual working conditions. The fixed-width expansion joint waterproof structure cannot adapt to expansion joints of various widths, and there is a defect that the expansion joint waterproof structure has low applicability. Utility Model Content

[0005] In order to improve the applicability of expansion joint waterproof structures, the present application provides an expansion joint waterproof structure for building construction.

[0008] Touch panels, two touch panels are provided, and the two touch panels are arranged opposite to each other;

[0009] A distance adjusting component, which is arranged between the two contact plates and is used to adjust the distance between the two contact plates;

[0010] Waterproof membrane, both ends of the waterproof membrane are respectively connected to two touch plates.

[0011] By adopting the above technical solution, the distance between the two touch plates is adjusted by the distance adjustment component, so that the touch plates are pressed against the inner wall of the expansion joint, and the waterproof structure is installed in the expansion joint. The distance between the two touch plates is adjusted according to the width of the expansion joint, so that the waterproof structure is adapted to expansion joints of various widths, thereby improving the applicability of the expansion joint waterproof structure.

[0012] Optionally, the distance adjusting assembly includes a distance adjusting sleeve and a bidirectional lead screw. Two distance adjusting sleeves are provided. The two distance adjusting sleeves are respectively threadedly connected to the two ends of the bidirectional lead screw. The ends of the two distance adjusting sleeves that are away from each other are respectively fixedly connected to two touch plates.

[0013] With the above technical solution, when the staff rotates the bidirectional lead screw to make the two adjustable sleeves approach each other, the distance between the two touch plates is reduced; when the staff rotates the bidirectional lead screw to make the two adjustable sleeves move away from each other, the distance between the two touch plates is increased. Through the above movement process, the distance between the two touch plates can be adjusted by rotating the bidirectional lead screw.

[0014] Optionally, a shift rod is fixedly connected to the bidirectional lead screw.

[0015] By adopting the above technical solution, the bidirectional lead screw is rotated by means of a lever, which makes it convenient for workers to exert force in a small space.

[0017] By adopting the above technical solution, one end of the guide rod is fixed to the inner wall of the expansion joint, and then the touch plate is guided and limited when the bidirectional lead screw is rotated, thereby facilitating the staff to adjust the distance between the two touch plates.

[0019] The pitch adjustment assembly includes a one-way screw and a pitch adjustment screw sleeve, two one-way screws are provided, and the two one-way screws are respectively arranged on both sides of the fixed seat, one end of the one-way screw is fixedly connected to the touch plate, and the other end of the one-way screw extends into the cavity, the one-way screw is slidably adapted to the fixed seat, the number of the pitch adjustment screw sleeve is the same as the number of the one-way screws and corresponds one to one, the pitch adjustment screw sleeve is threadedly connected to one end of the one-way screw extending into the cavity, and the pitch adjustment screw sleeve is rotatably connected to the fixed seat;

[0020] The fixing seat is provided with a driving assembly for driving the two pitch-adjusting screw sleeves to rotate simultaneously.

[0021] By adopting the above technical solution, the pitch-adjusting screw sleeve is rotated by the driving assembly, so that the pitch-adjusting screw sleeve causes the two one-way screws to move closer to each other or move away from each other. When the two one-way screws move closer to each other, the distance between the two contact plates is reduced; when the two guide screws move away from each other, the distance between the two contact plates is increased. Through the above movement process, the pitch-adjusting screw sleeve can be rotated to adjust the distance between the two contact plates.

[0022] Optionally, the driving assembly includes a driving roller, a driving bevel gear and a driven bevel gear, the driving roller is rotatably connected to a fixed seat, one end of the driving roller extends to the outside, and the other end of the driving roller extends into a cavity, the driving bevel gear is fixedly connected to the end of the driving roller extending into the cavity, the number of driven bevel gears is the same as the number of driving bevel gears and they are meshed one-to-one, and the driven bevel gear is fixedly connected to the pitch adjusting screw sleeve.

[0023] By adopting the above technical solution, the staff rotates the driving roller, and the driving roller rotates the adjusting screw sleeve through the active bevel gear and the driven bevel gear, thereby achieving the effect of driving the two adjusting screw sleeves to rotate simultaneously through the driving roller.

[0025] With the above technical solution, when the distance between the two touch plates increases, the roller rotates to release the waterproofing coil, so that the laying width of the waterproofing coil increases synchronously, and the torsion spring is stretched to accumulate elastic potential energy; when the distance between the two touch plates decreases, the torsion spring releases elastic force to make the roller rewind the waterproofing coil, so that the laying width of the waterproofing coil decreases synchronously. Through the above movement process, the laying width of the waterproofing coil is adjusted synchronously with the distance between the two touch plates.

[0026] Optionally, sealing pads are fixedly disposed on the sides of the two touch panels facing away from each other.

[0027] By adopting the above technical solution, the sealing between the touch plate and the inner wall of the expansion joint is increased by the sealing gasket, thereby improving the waterproof effect.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] The embodiment of the present application discloses a waterproof structure for expansion joints used in building construction.

[0038] Example 1

[0039] refer to Figure 1 A waterproof expansion joint structure for construction includes two touch plates 1, which are arranged opposite to each other. Sealing pads 15 are fixed on the sides of the two touch plates 1 facing away from each other, and a distance adjustment component 2 and a waterproof membrane 3 are arranged between the two touch plates 1.

[0040] The distance between the two touch plates 1 is adjusted by the distance adjustment component 2, and the laying width of the waterproof membrane 3 is adjusted synchronously until the two sealing pads 15 are respectively pressed against the inner walls on both sides of the expansion joint, and the sealing between the touch plate 1 and the inner wall of the expansion joint is increased by the sealing pads 15.

[0041] refer to Figure 1 Both ends of the touch plate 1 are provided with through holes 11, and guide rods 4 are arranged in the through holes 11. The guide rods 4 are slidably matched with the touch plate 1, and one end of the guide rods 4 is fixed to the inner wall of the expansion joint.

[0042] refer to Figure 1 and Figure 2 The pitch-adjusting assembly 2 includes a pitch-adjusting sleeve 21 and a bidirectional lead screw 22. Two pitch-adjusting sleeves 21 are provided, and one bidirectional lead screw 22 is provided. A lever 221 is fixedly connected to the middle position of the bidirectional lead screw 22. A plurality of levers 221 are provided, and the plurality of levers 221 are evenly spaced around the central axis of the bidirectional lead screw 22. Both ends of the bidirectional lead screw 22 are provided with threads, and the threads at both ends of the bidirectional lead screw 22 have opposite rotation directions. The two pitch-adjusting sleeves 21 are respectively threadedly connected to the two ends of the bidirectional lead screw 22, and the ends of the two pitch-adjusting sleeves 21 that are away from each other are respectively fixedly connected to the opposite sides of the two touch plates 1.

[0043] The staff passes the guide rod 4 through the through hole 11, and then fixes one end of the guide rod 4 to the inner wall of the expansion joint. Then the staff rotates the bidirectional screw 22 through the lever 221, and the bidirectional screw 22 drives the two distance adjusting sleeves 21 away from each other, so that the distance adjusting sleeve 21 drives the touch plate 1 to slide along the guide rod 4 until the touch plate 1 drives the sealing gasket 15 to press against the inner wall of the expansion joint.

[0044] refer to Figure 1 and Figure 3 The bottom of the opposite side walls of the two touch panels 1 are provided with a receiving groove 12, and the receiving groove 12 is opened along the length direction of the touch panel 1. The touch panel 1 is rotatably connected with a roller 13 in the receiving groove 12, and a torsion spring 14 is installed between the end of the roller 13 and the touch panel 1. The inner wall of the touch panel 1 at the receiving groove 12 is provided with an avoidance groove for installing the torsion spring 14.

[0045] refer to Figure 3 The end of the waterproof coiled material 3 is fixedly connected to the outer wall of the roller 13 , and the waterproof coiled material 3 is rolled up on the roller 13 .

[0046] When the two touch plates 1 move away from each other, the rotating roller 13 is triggered to rotate to release the waterproof coiled material 3. At this time, the torsion spring 14 is stretched and accumulates elastic potential energy.

[0047] The implementation principle of the expansion joint waterproof structure for construction in Example 1 of the present application is as follows: the worker rotates the bidirectional screw 22 through the lever 221, so that the two adjustable sleeves 21 drive the two touch plates 1 to move away from each other, until the touch plates 1 drive the sealing pad 15 to press against the inner wall of the expansion joint, and at the same time, the touch plates 1 cause the rotating roller 13 to release the waterproof coil 3. Through the above movement process, the effect of improving the applicability of the expansion joint waterproof structure is achieved.
