Description

Monolith pouring system for wall structure using a connecting means for expansion joint}

The present invention relates to a wall structure integral placing system using a construction joint connector. More specifically, in forming a wall structure that is continuously installed to a predetermined length such as the foundation of the soundproof wall, it prevents the discontinuity of the concrete placing by the construction joints inevitably occurring, and the construction is easy to construct regardless of the structure linearity. It is related to the integrated casting system of the pubic part.

The installation of the soundproof wall foundation part 10, which is a conventional wall structure, is made of a concrete structure having a structure which is continuously installed in a straight line or a linear shape with a predetermined length as shown in FIG. 1A, and the flange part 11 and the wall part 12 It is generally composed of.

Since it is a concrete structure, it can be molded into a predetermined shape using formwork. Usually, a formwork plate installed by manpower in the field is used, or when the cross section is small, it is also manufactured by mechanization means.

When the length of the wall to be installed is long, expansion joints, which are usually called construction joints, are installed. This is to absorb deformation due to shrinkage caused by concrete curing. The styropol is used as a kind of expansion joint material (13).

Since the expansion joint material 13 should be constructed between the wall sections, the flange 11 and the wall part 12 concrete A after the casting and curing are usually crossed one by one as shown in FIG. 1B. After installing the expansion joint material (13) between the pre-formed wall structure (12), the secondary wall concrete (B) is placed and cured again between the expansion joint material, the formwork is also the primary wall formwork and Secondary wall formwork will have to be divided and installed.

This process, above all, is not only an obstacle to air and economical wall construction due to excessive mold installation cost, but also a problem that structural and aesthetics are poor because the linearity of the wall is uneven when quality control for formwork is not properly performed. And

If the wall structure has to be formed with a certain curvature, the formwork itself has to be manufactured in a separate shape and shape, so the economical efficiency is lowered, and an effort to form a connection portion between the expansion joint material and the expansion joint is required. It has been pointed out that it is not easy to ensure the watertightness and durability of the.

An object of the present invention is to provide a construction joint connector that can be cast concrete integrally in the wall structure.

Another object of the present invention is to provide a construction joint connector excellent in workability and durability because the wall structure can be manufactured corresponding to the original straight line or curved line in the wall structure.

Another object of the present invention is to provide a construction joint connector that can be installed more easily formwork for wall.

Another object of the present invention is to provide a construction joint connector that can be manufactured in the form of a wall for the wall formwork plate curved or straight, but the lower shape to be produced in the shape of the base wall wall more quickly.

The present invention to achieve the above technical problem,

First, install the construction joint connector that can be freely installed by the support plate in the middle of the middle part of the wall structure to be installed, the double plate material is installed at a predetermined interval spaced apart at a predetermined interval so that the expansion joint is installed therebetween Construction joints including a connector to be installed,

Second, to form the formwork in a straight or curved form to make it easier to apply to the linear structure of the wall structure, and to be installed by fitting the connector for connecting the formwork to the construction joint connector,

Third, while forming the lower portion of the formwork to be the same as the shape of the lower portion of the wall structure and the same shape as the support plate of the construction joint connector is characterized in that the ease of workability and quality control.

Hereinafter, the best embodiments of the present invention will be described in detail with reference to the accompanying drawings in order to explain the present invention more clearly and easily, and embodiments according to the present invention may be modified in various other forms. The range is not limited to the embodiments described below.

Construction joint connector 100 of the present invention in the construction of the wall structure, the base plate 110 is blocked out therein; A double plate member 130 installed upward in the center of the support plate, and having expansion joint members 120 installed therebetween; And a horizontal connecting member 140 protruding from the outer surface of the double plate member.

The support plate 110 is a support plate formed so as to accommodate the dual plate member 120 to be described later, the dual plate member can be installed to be self-supporting, the overall shape is a rectangular shape as shown in Figure 2, the inside may be a double plate member The blocked out space C is formed. Both sides (D) of the support plate are formed to have the same or similar shape as the cross-sectional shape of the flange portion 11 of the lower part of the wall structure so that the support plate of the concrete and the connector formed as the wall structure can be easily provided without a separate connecting means. To be combined.

The double plate member 130 installed by the backing plate 110 may be vertically installed upwardly, and may be self-supporting without any other means. Therefore, the expansion joint 120 may be precisely installed at the portion where the intermediate intermediate expansion joint is to be installed. The receiving dual plate member 130 can be installed.

To this end, the upper surface of the support plate 100 is formed with a vertical groove 111 into which each member constituting the double plate member can be inserted. Each of the double plate members has a predetermined interval, and the expansion joint member 120 is sandwiched therebetween, and the double plate member 130 is doubled in the vertical groove 111 so that the double plate member 130 can stand freely at a secured interval while securing such a gap. The lower part of the plate member is inserted. The vertical groove 111 has a function to facilitate the installation of the double plate member without a separate skilled function. Because when using a plurality of connecting members, as the addition of a functional worker for the construction of the connecting member is less workability, because it may affect the quality control and air and construction costs.

Therefore, the depth of the vertical groove 111 is sufficient to have a depth enough to allow the double plate member to be self-reliant, and can not be limited depending on the thickness of the bottom plate of the support plate, but if the height of the double plate member is large, it is necessary An L-shaped reinforcing plate connecting the groove portions to each other may be further installed.

Although there is no material limitation in such a supporting plate, it can be harmonized with walls by making concrete, and there is an advantage of easily forming vertical grooves, but it is preferable to use steel to increase workability.

The double plate member 130 has a function of accommodating the expansion joint member 120 in the middle of the block-out space portion C of the support plate.

The cross-sectional shape of the plate member may be changed according to the cross-sectional shape, area, etc. of the expansion joint material to be installed, but if the styropole is used as the expansion joint material, the rectangular plate members are installed to face each other.

The height of the double plate member 120 can be adjusted according to the height of the wall structure and can be combined to a certain height in the field by connecting the dividers to each other, and may be produced at a constant height during the initial production, but the height of the wall structure is not large If not, it is advantageous in terms of workability to manufacture to have a predetermined height during the initial production.

When the expansion joint member 120 is inserted between the double plate member 130, the support of the double plate member is burdened by the lower portion of the double plate member inserted into the vertical grooves of the lower plate member and the expansion joint member may be in close contact with each other. In order to form a hole 131 through which the double plate member and the expansion joint material can communicate with each other, it is preferable to form the hole in advance during the double plate member and the expansion joint processing by determining its position and number.

In the present invention, the horizontal connection member 140 penetrating such a hole is installed to protrude to both sides of the double plate member. At this time, the horizontal connecting member 140 and the double plate member 130 by using a fastener such as a nut 141 to tighten the double plate member formed between the expansion joint member so that the double plate member and the expansion joint member is in close contact with each other. . At this time, the screw is formed on the outer surface of the horizontal connection member so that the nut can be fastened.

The protruding horizontal connecting member 140 is formed inside the wall concrete to be poured later, so that the double plate member and the wall concrete can be mechanically connected to each other so that they can be structurally integrated.

Construction fitting connector 100 including a double plate member 130 and the expansion joint member 120 formed on the support plate 110 is installed in the middle of the site where the wall structure is to be installed, acting as a kind of post structure, Between the formwork plate 200 for forming a wall structure is installed.

The formwork plate 200 is a formwork plate for forming a wall structure having a predetermined shape, and according to the linearity of the wall structure, the formwork plate 200a as shown in FIG. 3A or the curved formwork plate 200b as shown in FIG. 3B. Can be made. In general, the wall structure is designed to be straight, because it is advantageous in construction and economical, it is common that the wall structure is not constructed except in unusual cases.

In addition, the formwork plate of the present invention has the advantage that it can omit a part of the processing process of the formwork according to the wall cross-section when the lower portion is formed in advance in the shape of the flange portion. That is, by forming a lower portion of each form plate to the flange portion having the same cross-section and height so as to be in close contact with the side of the base plate to enable a more excellent formability of the form plate to be used, the support plate of the construction joint connector also the flange portion and If the formwork plate also has the same size and cross-sectional shape, it is possible to produce a wall structure having integrity.

By manufacturing the formwork in a curved shape rather than a straight line, as shown in Figure 3b, it is possible to produce a more efficient wall construction regardless of the linear structure of the wall structure.

Accordingly, in the present invention, in the state in which the post-construction joint connector is pre-installed, the formwork plate 200 is connected between the construction joint connector 100 according to the linear design of the wall structure. Formwork connecting means 300 is formed on the side of the double plate member in order to connect the formwork plate 200 to the double plate member 120 of the connector (100).

Figure 4a shows a specific example of the formwork connecting means 300 formed on both sides of the connector. Formwork connecting means are formed on both sides of the double-plate member and grooved channel member 310 so that the end of the formwork plate can be inserted into the formwork connector; and fastening to fix the formwork plate inserted in the channel member to the channel member Sphere 320; configured to include.

Channel member 310 is attached to the c-shaped channel on the side of the connector. The insertion groove (E) in which the end of the double plate member is inserted is formed, thereby making it very easy to install the double plate member.

By installing two formwork connecting means 300 on each side edge of the double plate member 120 constituting the construction joint connector 100, the formwork plates are installed to face each other, and the wall concrete is poured between the formwork plates. Walls can be formed.

The fastener 320 has a function that allows the formwork plate to be closely connected to the double plate member while maintaining the watertightness to the channel member, through the end of the double plate member inserted into the insertion groove with a bolt or as shown in Figure 3b By using the elastic force of the end of the channel member 310 to ensure that the end of the inserted double-plate member is engaged with the end of the channel member can be fixed.

After installing the construction joint connector 100 and the formwork plate 120 at the site where the wall structure is to be installed as described above, the wall concrete (F) is poured as shown in Figures 3a and 5, conventionally stretched There were many problems in quality control and constructability by dividing the parts between the parts where the joint material was installed and other parts, but in the present design, the wall structure can be integrally installed in the state where the expansion joint member 120 is pre-installed. There is an advantage that it can be produced all at once, not only beautiful appearance in a straight or curved shape, but also has the advantage of excellent quality control and constructability of concrete because it does not place the concrete with different parallax.

The construction joint connector of the present invention can be installed in the state where all the construction joint joints with expansion joints are installed in advance, so that the wall structure can be installed integrally so that the construction and the concrete quality management are easy. You can build the structure.
