Description

Contraction Joint Equipment in Jointing Point of Structure

The present invention relates to a contraction joint device of the structure joint, in particular one of the body

The structure contraction joint part of the structure of the specific form in which the sealant is previously filled in the side

Work in shrinkage joint treatment at the joint by inserting and installing on top

Minimizes defects in structures by improving the properties and inducing cracks at joints

The present invention relates to a contraction joint device of a structure that can

In general, when the cracks in the contraction joints of various structures are harmful to durability

Use sealant to block harmful factors with elastic sealing material or resin mortar.

Shrink joints are installed on concrete structures to prevent harmful cracking and cracking

Increasing the durability of the structure.

Shrink joints function when the structure shrinks due to a decrease in moisture content and temperature drop.

It is installed to suppress cracks and changes in temperature, humidity and drying shrinkage of structures.

To limit stresses and control cracks, and shrinkage of concrete

It creates small cracks and separations on the weakened surface, so the joints are installed to

Should be done.

As such, the technology for constructing contracted joints of structures requires constructability in contracted joints.

Compared with this, shrinkage is easy to run, share, durability, waterproof, and maintenance.

The method of installing the sound system shall be applied.

Filling the sealant after the saw cutting to the contraction joint of the structure, rod-shaped backing material and

There is a method of filling a tape-type backup material and injecting a sealant on the top.

Meanwhile, the shrinkage of tunnels, bridges, retaining walls, culverts, sideways and airport pavements of road structures

In case of construction of sound device, joint after removing curing and formwork after concrete pouring

After shaping, cleaning, and applying glue, install a stick backing or tape backing.

Bar sealant and the sealant's theme and parts

It is difficult to control the mixing and blending ratio of the main members of the runt, and to cure and form concrete

Hazardous cracks are generated until the house is removed, which adversely affects durability.

After sealing the shrinkage joint within a certain time after pouring the litt, sealant is injected but

Difficulties and construction of traffic opening timing, joint position, spacing, verticality after snow injection

There is a problem in that the surroundings are not cleared and fall off so that aesthetics are inhibited.

By the way, in the above series of work to fill the joint with the sealant

Work is temporary equipment work and saw cutting according to the position of construction surface of various structures to be installed.

You have to go through a very cumbersome process such as cleaning, adhering, filling

Therefore, it is difficult to install and it must be installed after a certain time after concrete pouring.

There is a problem that the harmful crack increases and the construction cost increases.

The present invention has been devised in view of the above matters,

A specific type of structure filled with resealant is applied to the contraction joint of the structure.

Insertion and installation prevents sagging and dropping of concrete and prevents various harmful cracks early

It can eliminate various work such as sawing and cutting, improving workability,

By smoothly responding to changes in shrinkage of the site, it is possible to minimize the occurrence of defects in the structure.

It is an object of the present invention to provide a contraction joint 400 of the structure joint.

The sealant 401 is filled in the upper space of the shrinkage joint structure and the shrinkage joint

Together with the body serves to seal the gap between the contraction joint of the structure.

In other words, the JP-type contraction joint structure is a silan which is a joint joint of various contraction joints

Manufactured with depth and width of filling

The 401 is pre-injected to cure.

The shrinkage joint structure filled with the sealant 401 is formed as shown in FIGS. 5, 6, and 7.

Installed at the bottom of the wall, allowing concrete to be poured on both sides of the shrink joint

The upper part of the structure is installed after concrete pouring.

Here, as shown in FIG. 4, the Y-shaped contraction joint structure filled with the sealant 401 is formed.

In installing on the wall and the lower part, the wall part is inside the wall formwork and the lower part is the foundation.

In the bottom formwork, the contraction joint structure anchor hole 404 is brought into close contact with a nail or the like.

And fit in line with the shrink joint structure.

When installing the structure and the upper part of the pavement surface, pour concrete,

And leveling the concrete pouring surface around the structure

Lee would have done so.

Shrink joint field of structure joint according to the present invention to achieve the above object

Its striking rod shape, its cross-sectional shape has \ shape, and contraction of structure

Shrink joint structure that is inserted into a predetermined gap between the groove

The sealant in the upper space side of the structure is slightly elliptically filled and contracted

Including sealant sealing the gap between the contraction joint of the structure and the structure

It is characterized by its point of construction.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

5, 6, 7 is less shrinkage joint device 400 of the structure joint according to the present invention

Figure showing the structure used.

Referring to Figure 4 the contraction joint of the structure joint according to the present invention is a contraction joint

It is large in sealant 401 wall part 402 anchor part 403 crack guide plate 406 as a structure

It is composed.

The shrinkage joint structure has a Y-shaped longitudinal section, and the shrinkage joint portion of the structure

It is inserted into the gap at a predetermined interval.

This JP shrinkage joint structure can be made of general synthetic resin bar

It is preferably made of soft synthetic resin.

In particular, the crack guide plate 406 is easy to be manufactured from a hard material.

In some cases, however, metals such as aluminum and stainless steel and non-ferrous metals

It may be made of a material such as genus. This shrinkage joint structure also

Depending on the type, it is manufactured to have a certain height and width, so that

It can be used only.

On the other hand, the JP-type contraction joint structure is made of soft synthetic resin material.

The new shrinkage characteristics of the body make it possible to cope with waterproofing and concrete shrinkage.

The sealant inner hole 405 is provided to improve the durability of concrete.

It is.

In order to ensure the shrinkage and adhesion of the concrete shown in Figure 4

As shown, W-shaped, uneven type on the wall 402 and the lower part 407 of the Y-shaped contraction joint structure

It consisted of such a structure.

As described above, the contraction joint device of the structure joint according to the present invention

The sealant is pre-installed and filled into a contraction joint structure that has been shaped into a specific shape.

The gap between contraction joints of various structures with contraction joints

As it is easily inserted and installed in a bird,

Improves aesthetics and workability, and needs various work according to on-site filling of sealant

To reduce construction costs, evenly fill the sealant

By installing it firmly, it is possible to remove the improvement of the structure and the cause of defects in advance.

There is an advantage to
