There are several ways to connect a built in rubber waterstop

Hengshui Baijin Rubber Products **** answers for you: the built-in rubber waterstop should be the buried rubber waterstop, and its connection method is mainly two: one is the cold connection method, and the other is the hot connection method.

1. The cold connection method is to use the special cold glue for the rubber waterstop, and the lap method is used to smooth the section of the waterstop with a grinder 5 10 cm, and the glue can be compacted, which has the advantages of high strength and fast solidification, convenient construction, time-saving and labor-saving, and can meet the general engineering quality requirements.

2. Hot connection method: on-site hot vulcanization joint is the use of hot vulcanization mold and raw film on-site vulcanization hot connection matched with the waterstop, which is difficult to construct, but the joint effect is ideal, and it is suitable for projects with strict requirements for engineering quality.

I think the built-in rubber waterstop you are talking about should be the embedded rubber waterstop, which is also known as the buried rubber waterstop or the central rubber waterstop.

Generally, there are two methods of this rubber waterstop joint: one is to use adhesive for cold jointing, and the other is to use hot vulcanization mold for hot jointing.

The following two joint methods are introduced separately:

1) The adhesive cold connection is the use of rubber waterstop special cold glue, the lap method is used to smooth the section of the waterstop joint with a grinder 5 10 cm, glue compaction, with the advantages of high strength, fast solidification, convenient construction, time-saving and labor-saving, can meet the general engineering quality requirements.

2) On-site hot vulcanization joint is the use of hot vulcanization mold and raw film matching with the waterstop on-site vulcanization hot joint, the construction is difficult, but the joint effect is ideal, suitable for projects with strict requirements for engineering quality.

In principle, rubber waterstops are not allowed to be lapped when they are connected. There are two main ways to connect the rubber waterstop, one is cold connection and the other is hot connection. The following is a detailed introduction of Hengshui Baijin Rubber Company:

1. Cold connection method: grind the thickness of the connection of the two sections of rubber waterstop by half with an angle grinder, wipe it clean, then apply the special glue of the rubber waterstop, and finally grind the two sections of the waterstop to bond together.

2. Hot bonding method. The hot joining method requires the use of a special hot melt machine, and the manufacturer reserves a section of unvulcanized head and provides raw film when producing rubber waterstops. Finally, it can be vulcanized by using a hot melt machine, which is difficult.

How to use: Rubber waterstops must be reliably fixed when binding steel bars and formwork. Prevents displacement when pouring concrete and ensures the correct position of the waterstop in the concrete.

Piercing and punching should only be made in the permissible part of the waterstop, for when fixing the waterstop. The effective waterproof part of the waterstop must not be damaged.

Commonly used fixing methods are: fixing with additional reinforcement; Special fixture fixing; Fix with lead wire and template, etc. No matter what kind of fixing method is adopted, the fixing method of the waterstop should be carried out according to the construction specifications required by the design, and it is necessary to ensure that the waterstop is accurately positioned, and the effective waterproof part of the waterstop is not damaged, so as to facilitate the concrete pouring.

Connection lap method.

1. Keep the concrete interface of the fixed waterstop flat and dry, remove the scum dust and sundries at the interface before installation, and fix the waterstop strip at the determined installation site with steel nails or glue. However, the face with grouting pipe must be pressed on the interface of the original concrete.

2. When the waterstop strip is connected, the parallel lap method is adopted, and the break point shall not be left in the middle, and the waterstop strip at the junction is strengthened and fixed with steel nails, and the reserved grouting connecting pipe on the waterstop strip is sleeved into the other waterstop strip of equality and connected to the two links.

3. According to the length of the installed water-stop strip, a tee is installed at about 30 meters, and the two ends of the tee straight line are about one end inserted into the water-stop strip, one end is inserted into the grouting connecting pipe, and the other T-shaped end should be inserted into the standby grouting to prevent the use of chemical slurry to stop water when the gap leaks.

4. The grouting connecting pipe in the connected waterstop strip must be firmly bonded with the tee connector, and the grouting pipe of the installed waterstop strip must be completely unobstructed. The spare grouting pipe installed on the tee should be placed in the direction of the interior wall.

Hello, the rubber waterstop is the use of rubber's high elasticity and constriction deformation, under various loads of compression tensile deformation. It is mainly used in the permanent joints and peripheral joints of underground foundations and tunnel projects, etc., to play the role of fastening and sealing, preventing water seepage and leakage, and ensuring the use of the life of engineering buildings. In many projects such as buildings, water conservancy, and bridges, there are certain requirements for elasticity, waterproofing and earthquake resistance, and the use of back-attached waterstops effectively meets the above requirements.

Hope it helps, thank you.

Rubber waterstop is a kind of rubber product, which is mainly used for waterproof and waterproof waterproof joints in engineering buildings.

Rubber waterstop is a kind of waterstop product mainly used to set up inside concrete such as concrete deformation joints and expansion joints, and has the ability to adapt to concrete expansion and deformation in the elasticity and structural form of rubber materials. The waterstop uses the high elasticity and compression deformation of rubber to produce elastic deformation under various loads, so as to effectively prevent water leakage and water seepage of building components, and play a role in shock absorption and buffering, which can ensure the service life of engineering buildings.

Rubber waterstop is a very widely used waterproof product, which can be used in bridge engineering, high-rise buildings, underground structures, dams, reservoirs, swimming pools, roofs and other building materials, expansion joints, and waterproofing of deformation joints of buildings. Rubber waterstops are mainly used for foundation works, underground facilities, tunnel culverts, water aqueducts, retaining dams, etc., which are located in construction joints and deformation joints when concrete is cast-in-situ.

The function of rubber waterstop: rubber waterstop is embedded in the deformation joint and the concrete is integrated with the concrete when pouring concrete, can effectively prevent the water seepage, water leakage at the deformation joint of the structure, and plays the role of shock absorption and buffering, thereby ensuring the waterproof requirements in the engineering structure.

The rubber waterstop connection can be constructed by a hot melt welding machine, and the specific methods are as follows:

1. Prepare tools first: a hot vulcanization composite welding machine, a grinding machine, a nail gun, a utility knife, a brush, and an iron ruler.

2. Preheat the welding machine 30 minutes in advance, and the temperature should reach 130 150 °C.

3. The waterstop joint is cut neatly, and the end is polished with a grinding machine. The grinding width is not less than 5cm.

4. Cut 10cm wide raw rubber connecting strip and 1cm wide raw rubber connecting strip respectively.

5. Turn off the hot-melt welder and lay the waterstop joint on the bottom plate of the welder.

6. Put the 1cm wide raw rubber connecting strip into the middle of the seam.

7. Spread the 10cm wide raw rubber joint on the grinding surface of the waterstop to ensure that the width of both sides of the joint is equal.

8. Close the hot melt welding machine, tighten the bolts, turn on the power for 5 minutes, tighten the bolts again and pressurize (until they can't be screwed), continue to heat for 5 minutes, and turn off the welding to finish.

9. After the hot-melt welding machine is cooled for 20 minutes, take out the waterstop and carry out the visual inspection of the welding, and the installation operation can be carried out only after it is qualified.

Butterfly rubber waterstop is a kind of rubber waterstop, which has the characteristics of novel design, good waterproof and waterproof performance, and affordable performance. The butterfly rubber waterstop is made of natural rubber and various synthetic rubber as the main raw materials, mixed with a variety of additives and fillers, and manufactured by plastic, vulcanization, mixing and other processes.

The main points of butterfly rubber waterstop installation are:

1) Truncated and centered, symmetrical overhead. Cut the appropriate length and mark the midpoint of the butterfly-shaped buried waterstop; The waterstop is erected on the formwork trolley, and the midpoint of the waterstop coincides with the midpoint of the trolley.

2) Rooting to the bottom, fixed in the center. The butterfly-shaped buried waterstop should be installed in its entirety to the lining substrate; and should be fixed on the midline of the lining thickness.

3) Spread the wings and press the ribs, and install the mold nails. Flatten the flange of the waterstop on one side of the end template, then press the middle rib of the butterfly-shaped buried waterstop, and fix the waterstop with iron nails while installing the end template.

4) East and west transverse boards, bridge capping. When the butterfly-shaped buried waterstop is installed on the top of the tunnel, it is necessary to rely on a piece of east-west plank, first nail the first section of the waterstop to the east-west plank, and then place the east-west plank horizontally; The two ends of the wooden board are nailed to the installed end touch board, and the setting of the waterstop at the top of the cave is solved through the bridge function of the east and west wooden boards.

5) Don't forget to remove the mold, spread your wings and shape it. When the lining concrete is removed after it reaches a certain strength, it must be noted that the waterstop section that does not automatically return to its natural shape must be manually shaped.

Rubber waterstop is an important part of building waterproofing, if there is a problem with the installation of the waterstop, it is very troublesome to maintain it later. When installing the rubber waterstop, pay attention to the following 5 points, and complete the installation of the waterstop in one step.

Rubber waterstops, joints should be kept clean and tidy.

1: The shape of the joint should match

Under normal circumstances, the installation of the rubber waterstop is a cold connection method, and the joint of the rubber waterstop needs to be cut to a matching size, so that there will be no gaps or inability to install.

2: Keep the interface clean

After the shape of the joint is sharpened, wipe the joint clean and keep it dry, so as to increase its sealing degree and ensure the water-stopping effect.

3: Eliminate air bubbles

Keep the rubber waterstop clean, connect it according to the design drawings, and stick it together with rubber first, and there can be no bubbles like the mobile phone film, otherwise it will affect the effect for a long time.

4: Keep it vertical

In the process of connection, the joints should be as vertical as possible, with fewer acute and obtuse angles, so as not to affect the difficulty of pouring concrete in the later stage.

5: Keep your distance from the rebar

When installing the rubber waterstop, it is necessary to keep a certain distance from the steel bar, leave a suitable space for the concrete, and vibrate the bubbles mixed in it when pouring to avoid loosening.

The above are the key points when installing the rubber waterstop, and all the builders should take a small notebook to memorize it

<><How to connect the rubber waterstop:

1. First of all, prepare the corresponding tools, such as welding machine, grinding machine, nail gun and knives, etc.

2. Then turn on the welding machine half an hour in advance to let it reach 130 degrees.

3. Then cut the waterstop joint flush, and then polish the end with a grinder.

4. Lay the waterstop joint on the welding machine, use the adhesive strip to bond, and tighten the bolts.

5. Finally, take out the waterstop, overhaul the welding position, and the composite material can be installed.

When the rubber waterstop is welded, the surface of the floating skin and rust should be cleaned. If there is a sand hole and nail hole, it should be welded and repaired. If the Kirimori joint is long, lap welding can be used.

However, the length should not be less than 20 mm. Never choose to weld by hand. After welding, it should be checked one by one, and there should be no bubbles and slag inclusions in the local posture.

What to pay attention to in the construction of rubber waterstops

1. When binding steel bars and formwork, the rubber waterstop should be reliably fixed to avoid displacement during pouring. Moreover, when fixed, only holes can be punched in the allowable parts, and the waterstop itself cannot be damaged.

2. If the transportation conditions are not good, when the waterstop can be connected on site, hot pressing gluing can be used, but the waterstop joint should be smooth and clean, and the strength should be maintained. In addition, the waterstop has sufficient deformation capacity, and the waterstop with intersections can be selected, and the straight section is bonded.

3. During the construction of the waterstop, the family should avoid being punctured by the sand and gravel in the concrete, so when pouring, do not use too much force, and if the waterstop is found to be damaged, it should be repaired in time to avoid joint deformation. And when positioning the waterstop, keep it flat and there should be no kinks. Otherwise, it will affect its water-stopping effect.

In addition, the concrete should be sufficient, to ensure the adhesion between the waterstop and the concrete, and if the site conditions allow, hot vulcanization can also be used to connect.
