Description

Joint structure of building using anchor and plate

The present invention relates to a structure joint structure using an anchor and a pressing plate. More specifically, it relates to the waterproofing structure of the joint portion of a structure that is installed to prevent leakage of flowing water after construction in the connection portion of the water channel structure, such as an agricultural water channel structure, and a joint part of an existing water channel structure and a joint part of a new water channel structure. The present invention relates to a structure of a structure joint using an anchor and a press plate that effectively secure a waterproofing effect and easy quality control thereof.

As shown in Fig. 1, the connecting portion of a structure installed on a support column with a constant length in the same cross-section as a water channel structure (a farm channel with water flowing inside, a box structure, etc.) usually inserts or fills expansion joints and filling materials such as plywood and sealing materials. After that, the method of continuously installing the concrete structure on both sides of the connection part is used. This method deteriorates the durability of concrete as the channel structure hardens over time. Especially, in the case of the joint, the plywood is corroded by moisture, water, etc., or the sealing material is leaked from the joint. There is a problem, and there is a problem that a huge maintenance cost is required to repair it, and even when the index plate is installed separately, it is simply treated to be inserted into the connection junction of the waterway structure, so that the waterproof effect is hardly exhibited after construction. There is a problem that it is difficult to expect the effect of the index plate greatly.

In addition, in the case of the connection part of the waterway structure, the worker cannot connect the waterway structure at the level of the plastering work of the worker because of the real problem that the construction management is difficult even though the workability of the work itself is insufficient because the space for work such as maintenance work is not wide. As the site is being processed, it is required to adopt the construction means of the systematic waterway structure connecting parts for easier quality control. Therefore, the present inventors can exhibit a better waterproof effect on the connection part of the waterway structure, and developed a construction means for the connection part of the waterway structure that can ensure a systematic waterproof quality.

It is an object of the present invention to provide a structure of a joint structure using anchors and compression plates that can effectively secure a waterproofing effect after construction in connection parts of structures such as waterway structures, thereby reducing unnecessary maintenance costs.

Another object of the present invention is to provide a structure of the structure of the joint structure using the anchor and the compression plate that can be applied to the joint of the new channel structure as well as the existing channel structure.

Another object of the present invention is to provide a structure of the structure of the joint structure using anchor and compression plate capable of systematic quality control in the construction of the joint structure of the waterway structure to be simply constructed.

In order to solve the above technical problem, the present invention uses an index plate to secure the waterproof function of the waterway structure, but the index plate is to prevent the degradation of the waterproof effect caused by separation from the original installation position after construction. The key technical means is to provide the press installation means (anchor and press plate) of the device, and to use the mechanical means instead of forming the finishing layer by the plasterer's work to finish the connection part of the waterway structure. It is characterized by forming a finishing layer.

Hereinafter, the most preferred embodiment of the present invention will be described in detail with reference to FIGS.

Structure joint structure using anchor and compression plate of the present invention,

Between the joints 100a and 100b surface-treated to a certain depth and area for the construction of the structure joints, the reinforcing layer 10 is cast and cured to a certain thickness, including the expansion joint material 11; A plurality of anchors 20 which are embedded at predetermined intervals at both junctions to penetrate the reinforcement layer and protrude above the reinforcement layer; An index plate 30 inserted into the plurality of protruding anchors and installed on an upper surface of the reinforcing layer; A member for pressing and fixing the index plate on the upper surface of the reinforcing layer, the pressing plate being inserted into the protruding anchor and fixed to the upper surface of the index plate by the fastening device 50; Including the projecting anchor, the index plate and the compression plate, including a cured finishing layer 60, and cured to a certain thickness, and will be described on the basis of the case of the joint of the existing waterway structure, according to the construction order Explain step by step.

2A and 2B are cross-sections (chips) to be cut by chipping both joint concrete (including reinforcing bars) in a rectangular cross-sectional shape in order to apply the present invention to both joint portions 100a and 100b of the existing waterway structure. Part) is shown in plan and three dimensions. That is, it acts as an accommodation space (chipping space) including the reinforcing layer, the index plate, and the finishing layer, which will be described later. After cutting, air blasting is carried out to remove the residue after cutting, and rust is removed when the rebar is exposed. Applying a rust inhibitor, the size of the chipping portion may be changed according to the design in consideration of the cross-sectional size and the waterproof effect of the target channel structure, the width (W) is 34 CM, the depth (H) is usually 6CM or less, reference numeral 12 denotes an expansion joint material such as plywood, and is cut together when chipping. Since the expansion joint material is cut during the chipping process as described below, a material serving as a separate expansion joint material is formed.

3A and 3B illustrate the case in which the reinforcing layer 10 is formed in the chipping space in plan and three-dimensional manner, and a new expansion joint is formed in the middle of the reinforcing layer 10. The new expansion joint material 11 uses a sealing material rather than using a material such as plywood used in the existing structure, and first forms a reinforcing layer between the new expansion joint material, and then inserts a sealing material therebetween.

In the present invention, the reinforcing layer 10 is to increase the pressing effect of the index plate 30 to be described later by flattening the chipped surface A, and the anchor 20 penetrates the index plate as shown in FIG. 4A to fix the index plate. As it is embedded in the chipping surface (A) to a certain depth, the anchor 20 is to be formed for the reinforcement of the chipping surface when forming a hole to be easily formed on the chipping surface. The reinforcement layer 10 may be formed to a predetermined thickness by spraying using a spray gun in the field, and may be formed by a plastering operation of an operator, but it is preferable to form an electron for quality control. Since the hole is formed, it is preferable to use a high strength polymer motor, but is not limited thereto. In addition, in order to secure the adhesive performance of the reinforcing layer 10 and the existing chipping surface (A) to form an uneven surface or apply a concrete adhesive.

4A and 4B show a planar and three-dimensional view of a state in which a plurality of anchors 20 are buried along the joint portion at predetermined intervals at both joint portions 100a and 100b in a state where the reinforcing layer 10 is formed. Installation spacing (D), buried depth, diameter of the anchor 20 can be changed depending on the area of the chipping surface A formed on both joints, the size of the required index plate, etc., the installation spacing is 20CM or less, the buried depth is the reinforcing layer ( 10) to 6CM or more, the diameter of the anchor is less than 10MM is preferable in terms of economics and construction. In order to bury the anchor 20, first, a hole penetrating the reinforcing layer 10 and the chipping surface A is first formed by using a mechanical device such as a drill, and then the anchor 20 is inserted into the anchor 20. The voids are filled with filler 21, such as epoxy, to anchor the anchors. The tip end of the anchor is formed to slightly protrude above the reinforcing layer 10. The index plate, a fastening device, and a wire mesh, which will be described later, are inserted into the front end, and the stop plate 30 is pressed against the reinforcing layer 10 so as to be installed. And the front end portion is formed with a female thread so that the nut which is the fastening device 50 to be described later is fastened.

5 shows a three-dimensional process of applying the sealant 60 on the reinforcement layer 10 having the anchor. That is, it is a process of attaching the index plate 30 to be described later as a physical adhesive. Such a sealant application can be optionally adopted, and the thickness thereof is preferably 5 mm or less.

6a shows that the index plate 40 is inserted into the anchor 20 by means of a fastening device 50 such as a nut using a crimping plate 40 across both joints to the reinforcing layer 10 provided with the anchor, The state in which the wire mesh 70 is further formed on the device 50 is shown in plan view.

6B shows a front view of the index plate 30 separately. The water stop plate uses a product used for the retaining wall and the outer wall, and a normal water stop plate is composed of both wing parts 31 and the central protrusion part 32. As a method, the index plate itself is inserted into and installed at the junction of the structure. However, such an installation method has a problem in that the index plate is separated from the original installation position after construction, which implies a problem in the construction method rather than a defect of the index plate itself, but a method of solving the problem is not devised and follows the conventional construction method. I'm doing it. In order to solve this problem, the present inventors use an index plate in which the index plate 30 is inserted into the anchor 20 insertion hole 33 so that the index plate is fixed by the anchor 20 so that the index plate is not separated from the original installation wit. At the same time, the problem of the waterproof state due to the hole formed in the index plate was solved by using the pressing plate 40. That is, as shown in FIG. 6B, the groove 34 capable of accommodating the pressing plate 30 in the index plate 30 is formed together with the hole 33 so that the pressing plate can be pressed against the reinforcing layer 10 so that the waterproofing effect is not deteriorated. It is to avoid. The press plate 40 is preferably an iron plate, but it is also possible to use a silicon plate for weight reduction and corrosion prevention. After the stop plate 30 is installed, the fastener 50 such as a nut is fastened to the female screw portion formed at the tip end of the anchor in order to press the stop plate to the reinforcing layer 10. In the case of the fastening device 50 and the crimping plate, a wire mesh 70 may be installed to secure a bonding force with the finishing layer 50 in FIG. 6a, and further, may have an effect of preventing additional surface cracks by the wire mesh. have.

The size of the index plate 30, the pressing plate 40, and the wire mesh 70 may also be changed according to design factors, but the index plate has a width of 230 mm or less, and the pressing plate is made of 4.5 mm thick and 5 cm wide. In the case of wire mesh, it is desirable to install it in 13 cm or less.

FIG. 7 illustrates a state in which the finish layer 60 is formed in the chipped space in a state where the index plate and the wire mesh are installed in the anchor.

Like the reinforcing layer 10, the finishing layer 60 is formed by spraying with a spray gun, and finishes by injecting a sealing material injecting a sealant as an expansion joint material between both joints.

In the joint part of a structure such as a waterway structure, a conventional method of inserting and installing a watermark plate or simply injecting a sealing material is inadequate to secure a waterproof effect after construction, which requires considerable cost and labor for maintenance. By this design, the installation effect of the index plate can be increased, and through the quality control method, the construction of the joint structure of the structure that can be efficiently maintained is possible while ensuring the waterproofing effect as much as possible. It can also be used for waterproofing of flowing structures such as flowing water, and its effect is excellent.
