Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a bridge deck expansion joint rubber water stop strip installation device. Background Art

[0002] In bridge construction, setting up bridge deck expansion joints is an essential construction link. It can achieve a certain range of free expansion and contraction under the deformation and vibration of the bridge deck, so as to adjust the displacement between the superstructures caused by vehicle loads or bridge construction materials, thereby ensuring the flatness, firmness and safety of the bridge deck. In addition, rubber waterstops are generally required in bridge deck expansion joints. Their main function is to prevent water and dust, and prevent debris from entering the expansion joints and affecting their normal expansion and contraction. The existing installation method is often manually installed by construction workers.

[0003] However, practice has shown that the existing installation method of rubber waterstop strips for bridge deck expansion joints has the following problems: since the rubber waterstop strips need to be in close contact with the bridge deck expansion joint grooves, the friction between the two is also relatively large, so it is often difficult to insert smoothly, requiring construction workers to spend a lot of time and manpower to install, and the construction efficiency is low.

[0004] Therefore, it is necessary to invent a bridge deck expansion joint rubber water stop strip installation device to solve the above problems. Utility Model Content

[0016] A bridge deck expansion joint rubber water stop strip installation device, as shown in the attached Figure 1 As shown, it comprises a rectangular bracket 1, a small electric winch 2 is tied to the front crossbar of the rectangular bracket 1, a longitudinal diagonal bar 3 with a high front and a low rear is fixed in the middle of the rear crossbar of the rectangular bracket 1, a slide groove 4 which passes through the longitudinal diagonal bar 3 is opened, a clamping and fixing device is slidably connected in the slide groove 4, a fixed pulley 5 is arranged at the end of the longitudinal diagonal bar 3, a steel wire rope of the small electric winch 2 is wound around the fixed pulley 5, and a hook 6 is fixed at the end of the steel wire rope;

[0017] The clamping and fixing device includes an adjusting bolt 7 and two U-shaped clamps 8. The rod of the adjusting bolt 7 is slidably inserted in the slide groove 4. The two U-shaped clamps 8 are respectively installed at both ends of the adjusting bolt 7, and the two U-shaped clamps 8 are symmetrical about the longitudinal diagonal rod 3.

[0018] The combined structural design of the rectangular bracket 1, the small electric winch 2, the longitudinal diagonal rod 3, the fixed pulley 5, and the hook 6 in the utility model realizes the smooth installation of the rubber water stop strip of the bridge deck expansion joint by the device, so that after the hook 6 at the end of the wire rope is fixed to one end of the rubber water stop strip of the bridge deck expansion joint, the rubber water stop strip of the bridge deck expansion joint can be pulled from one end of the bridge deck expansion joint to the appropriate position at the other end by starting the small electric winch 2. The operation is simple, time-saving and labor-saving, and the construction efficiency is greatly improved; the structural design of the slide 4, the adjusting bolt 7, and the U-shaped clamp 8 is convenient for fixing the rectangular bracket 1 to the ballast retaining wall at the construction site, thereby forming a stable support point, improving the structural stability of the device during operation, and at the same time standardizing the installation process and achieving good installation effect, effectively ensuring the construction quality. In addition, the U-shaped clamp 8 can also be adjusted in position through the slide 4 and the adjusting bolt 7, which increases the flexibility of the structure.

[0019] A fixing nut is screwed onto the tail end of the adjusting bolt 7 , and the two U-shaped clamps 8 are fixed to the slide slot 4 through the adjusting bolt 7 and the fixing nut.

[0020] The structural design of the fixing nut and the adjusting bolt 7 enables the two U-shaped clamps 8 to be fixed to the slide slot 4 after being adjusted to a suitable position through the slide slot 4.

[0021] As attached Figure 1 As shown, each U-shaped clamp 8 has two clamping plates each with a fixing hole, and each U-shaped clamp 8 has two fixing holes with fastening bolts 9 inserted therein, and the tail end of the fastening bolt 9 is screwed with a fastening nut.

[0022] The structural design of the fastening bolts 9 and the fastening nuts facilitates clamping and fixing the U-shaped clamp 8 to the ballast retaining wall at the construction site, so that the device and the ballast retaining wall can be firmly connected.

[0024] The structural design of the rubber anti-skid layer I can increase the friction between the outer wall of each U-shaped clamp 8 and the outer wall of the longitudinal diagonal rod 3; the structural design of the rubber anti-skid layer II can increase the friction between the inner wall of each U-shaped clamp 8 and the outer wall of the ballast retaining wall at the corresponding construction site, which not only prevents slipping and falling off, further improves the stability of the device during operation, but also can avoid damage to the ballast retaining wall.

[0025] The slide groove 4 is in the shape of an elongated strip.

[0026] During construction, firstly, one end of the rubber water stop strip of the bridge deck expansion joint is inserted into the expansion joint of the bridge deck, and the length of the inserted part ranges from 20cm to 30cm. At the same time, the inserted part is firmly tied with wire and connected with a rope; then the device is placed on the inner side of the ballast retaining wall at the other end of the bridge deck expansion joint (the end that is not inserted into the rubber water stop strip), and the end of the longitudinal diagonal rod 3 fixed with the fixed pulley 5 is extended to the outside of the bridge deck through the disconnection of the expansion joint of the ballast retaining wall; then the clamping and fixing device on the longitudinal diagonal rod 3 is slidably adjusted to a suitable position, so that the two U-shaped clamps 8 are clamped on the ballast retaining wall respectively. The outer walls of the two sections of the wall where the wall expansion joint is disconnected are fixed by tightening the fixing nuts and the fastening nuts in sequence; then the steel wire rope of the small electric winch 2 is passed around the fixed pulley 5 at the end of the longitudinal diagonal rod 3, and the hook 6 at the end of the steel wire rope is connected to the rope of the rubber waterstop strip of the bridge deck expansion joint; finally, the small electric winch 2 is turned on to pull the rubber waterstop strip of the bridge deck expansion joint along the bridge deck expansion joint to a suitable position, thereby completing the installation and use of the device; overcoming the problems of time-consuming, labor-intensive and low construction efficiency in the existing installation method of the rubber waterstop strip of the bridge deck expansion joint.
