Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic engineering construction. Specifically, it relates to a device for jointly fixing a water-stop copper sheet with a steel formwork and a wooden formwork. Background Technique

[0002] The water-stop copper sheet is an excellent water-stop material and is widely used in the anti-seepage projects of hydraulic engineering. Commonly, the water-stop copper sheet is embedded with rubber or a water-stop steel plate, etc. to form a water-stop material together, making the anti-seepage system more firm. The water-stop copper sheet is often buried at the bottom of hydraulic structures such as ship locks, sluice gates, and channels, or poured into construction joints and expansion joints, and is arranged at the parts of some hydraulic structures such as water retaining, water conveying, and water storage that are prone to seepage.

[0003] Currently, it is more common to use clamps, brackets, and wooden formworks to fix the water-stop copper sheet. This fixing method is difficult to accurately position the water-stop copper sheet, and the wooden formwork is easily deformed and displaced due to moisture; the integrity of the formwork is poor, and it cannot ensure that the construction joint and the center line of the double water-stop copper sheets are on the same straight line. During construction, it is also easy to have misalignment, and quality problems such as formwork displacement and slurry leakage are likely to occur, thus unable to guarantee the construction quality; at the same time, for parts with high anti-seepage requirements, multiple copper sheets are often installed in a butt-jointed, folded, or lapped manner for centering across the joint. Such installation is also relatively cumbersome, so there is an urgent need for improvement. Summary of the Invention

[0023] The present invention will be further described below in conjunction with embodiments. The description of the following embodiments is only used to help understand the present invention. It should be noted that for those of ordinary skill in the art in the technical field, without departing from the principle of the present invention, several improvements and modifications can still be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0024] Embodiment 1

[0025] As Figures 1 to 3 shown, a device for jointly fixing copper waterstops with steel formwork and wooden formwork includes a first steel formwork 1, a second steel formwork 2, a first copper waterstop 3, a second copper waterstop 5, a first wooden formwork 4, and a second wooden formwork 6; wherein, the first steel formwork 1 and the second steel formwork 2 are arranged in parallel at intervals in the horizontal direction. It should be noted that the first steel formwork 1 and the second steel formwork 2 have the same shape and size to ensure that when arranged in parallel at intervals, the first steel formwork 1 and the second steel formwork 2 overlap in the thickness direction.

[0026] On the opposite sides of the first steel formwork 1 and the second steel formwork 2, there are both notches, and the two notches jointly enclose to form a U-shaped groove; the first copper waterstop 3 is arranged in a strip shape to form two wings extending in the horizontal direction and a U-shaped protrusion 10 protruding laterally from the middle part, and the U-shaped protrusion 10 is located in the U-shaped groove, so that the first copper waterstop 3 can be prevented from displacing in the horizontal direction. It should be noted that before processing the U-shaped groove, it is necessary to preferably consider the size of the U-shaped protrusion 10 of the first copper waterstop 3, and process the U-shaped groove according to the size of the U-shaped protrusion 10 to ensure that the U-shaped protrusion 10 can be inserted into the U-shaped groove.

[0027] In addition, the first steel formwork 1 and the second steel formwork 2 can be used as concrete formwork by themselves, and can also fix the first copper waterstop 3. During the process of hoisting the formwork and fixing the first copper waterstop 3, the first copper waterstop 3 is welded to the first steel formwork 1 and the second steel formwork 2, so that the production of the concrete steel formwork can also fix the first copper waterstop 3 at the same time.

[0028] One side of the first wooden formwork 4 is inserted into the recessed position of the U-shaped protrusion 10 of the first copper waterstop 3. The first wooden formwork 4 can be used as concrete formwork by itself or as a fixing device for the first copper waterstop 3. It should be noted that when making the first wooden formwork 4, the width of the first wooden formwork 4 needs to be set so that the width of the first wooden formwork 4 is consistent with the opening width of the recessed position of the U-shaped protrusion 10.

[0029] By using the first wooden formwork 4 for construction, it is more economical than the steel formwork, and the first wooden formwork 4 is easy to install, disassemble and transfer. After the first steel formwork 1 and the second steel formwork 2 fix the first water-stop copper sheet 3, the first wooden formwork 4 is used as an auxiliary fixing device, which can not only prevent the coarse aggregate from being squeezed during the concrete pouring process so that the first water-stop copper sheet 3 is displaced and deformed, but also the first wooden formwork 4 used is easier to cut and splice. According to the shape of the building to be built, the first wooden formwork 4 can be flexibly used as a template and a device for fixing the first water-stop copper sheet 3.

[0030] During the construction of water conservancy projects, in order to better improve the anti-seepage effect, generally, multiple water-stop copper sheets need to be arranged on the construction joint facing the water surface. In this embodiment, a second water-stop copper sheet 5 is provided, and the second water-stop copper sheet 5 is arranged in the same shape as the first water-stop copper sheet 3, that is, the second water-stop copper sheet 5 and the first water-stop copper sheet 3 have the same model, the same size, and the same installation direction.

[0031] Specifically, the other side of the first wooden template 4 abuts against the U-shaped protrusion 10 of the second water-stopping copper sheet 5, one side of the second wooden template 6 is inserted into the recessed position of the U-shaped protrusion 10 of the second water-stopping copper sheet 5, and the other side of the second wooden template 6 extends in a direction away from the first wooden template 4.

[0032] Similarly, when making the second wooden template 6, the width of the second wooden template 6 needs to be set so that the width of the second wooden template 6 is consistent with the opening width of the recessed position of the U-shaped protrusion 10 of the second water-stopping copper sheet 5, so that the second water-stopping copper sheet 5 is tightly attached to the second wooden template 6.

[0033] In addition, the first water-stop copper sheet 3 is also bonded to the first wooden formwork 4, and the second water-stop copper sheet 5 is also bonded to the first wooden formwork 4 and the second wooden formwork 6. For example, a thin layer of soft glue is brushed on the connection position between the second wooden formwork 6 and the second water-stop copper sheet 5, so that the second wooden formwork 6 and the second water-stop copper sheet 5 are more tightly connected, and the bonding method will also make it easier to disassemble the formwork.

[0034] In addition, considering the disassembly performance, the welding connection method used by the first water-stop copper sheet 3 and the first steel template 1 and the second steel template 2 is a spot welding connection method. The spot welding connection method makes it easier to disassemble the first steel template 1 and the second steel template 2, thereby facilitating the separation of the first water-stop copper sheet 3 from the first steel template 1 and the second steel template 2.

One side of each profile bar 7 is also in contact with the first wooden formwork 4 and the second wooden formwork 6. Each channel steel 8 extends along the up-down direction, and the channel steels 8 are arranged at intervals on one side in the thickness direction of the second steel formwork 2. Each channel steel 8 is welded to the second steel formwork 2.

[0037] In this embodiment, there are 6 profile bars 7 provided, and every 3 of them are arranged at intervals on one side of the first wooden formwork 4 or the second wooden formwork 6. In this embodiment, there are 5 channel steels 8 provided, and the 5 channel steels 8 are arranged at intervals on one side of the second steel formwork 2 and are spot-welded to the second steel formwork 2.

In addition, reinforcing bars are arranged on one side of each profile 9, and the reinforcing bars are used for welding with the internal reinforcing bars of the concrete. In this way, the entire device system can be made more stable and reliable.
