Description
BACKGROUND OF THE
Generally, concrete pouring work is done by making molds according to the shape of the building, injecting the concrete by installing the formwork on the pillar that forms the skeleton of the building, and removing the form when the concrete is dried and cured.
At this time, an anchor for constructing various structures is coupled to the ceiling of the building formed through the concrete, and the anchor can be inserted into the insert embedded in the concrete and be coupled.
Here, as a method for burying the insert in the concrete, there is a post-install method in which the insert is installed after perforating the hole after the concrete curing, and a method of placing the insert in advance and placing the concrete (cast-in) method, and pre-installation method is mainly used.
Figs. 1A and 1B show an example of a conventional insert.
As shown in FIGS. 1A and 1B, a
In this case, the structure includes a duct, a ceiling board skeleton, an electric wiring, etc., and ceiling construction can be completed by installing various structures on the anchor (a) and connecting the ceiling board along the installed ceiling board framework.
However, when the anchor (a) is supported by the surface of the concrete (c) and a lateral pressure is applied to the anchor (a) Cracks are easily generated and the generated cracks are often propagated to the inside, so that not only the supporting force of the
In addition, a gap is frequently formed between the form m and the lower surface of the
In order to dispose the reinforcing bar on the side of the concrete slab, a hole is formed in the side wall of the form (m) to insert the reinforcing bar and the concrete has to be laid, so that the form is damaged due to the hole, .
Further, when the heat insulating material is installed in the formwork m, the heat insulating material is often separated and separated easily after curing of the concrete. Therefore, there is a problem that a complicated procedure is required to puncture concrete in order to install a separate fixing member.
Meanwhile, in order to increase the bearing capacity of the concrete (c), when a reinforcing bar is placed in the concrete (c), a separate reinforcing bar spacer is required to form a reinforcing bar spaced apart from the concrete.
In addition, since unnecessary material cost and installation period are consumed in order to install and provide the
Further, since the thickness of the concrete slab is not constant depending on the use or size of the building, if the thickness of the slab is changed and the spacing of the reinforcing bars is changed, a separate spacer corresponding to the spacing of the reinforcing bars must be prepared and installed.
On the other hand, in order to check the horizontal or thickness of the slab when casting the concrete (c), a leveler such as a bar marked with a height was used. In the case of using a product having a long dimension, it is necessary to remove the protruded portion, which is inconvenient for the operation.
As described above, when the concrete (c) is laid, the design and construction are complicated to separately provide and install the
In order to solve the above problems, it is an object of the present invention to provide a composite insert device for a concrete installation, in which an anchor for installing various structures on concrete is combined and a composite function is provided by one device, The problem is solved.
According to an aspect of the present invention, there is provided a method of inspecting a concrete structure, the method comprising: providing a supporting body portion inserted and fixed in a heat insulating material provided along a form in which concrete is laid, A lifting body part including a fastening part screwed into the hollow fastening hole so as to be selectively moved up and down and having an anchor coupling groove formed therein and a leveling supporting part integrally projecting radially outward along an upper edge of the fastening part; And a penetration inducing portion formed at a lower portion of the engaging portion and including a wedge-shaped penetrating portion which is narrowed from the upper portion to the lower portion so as to penetrate the heat insulating material by pressure, Provided is a composite insert device for use in concrete.
Here, the outer circumference of the support body portion includes a plurality of spaced apart fixed protrusions including an upwardly sloping slide portion for pressing the heat insulating material to be inserted into the lower portion thereof, and a fastening portion for forming a stepped portion for fastening the heat insulating material in the upper end portion thereof .
At this time, the penetration guide portion and the support body portion are made of reinforced synthetic resin, and the lower end of the penetration guide portion is insert-molded into a fixing nail inserted into the mold through the heat insulating material, Preferably, the upper end of the threaded portion formed on the outer periphery of the coupling portion is provided with a stopper portion which is engaged with the upper edge of the supporting body portion and restrains the threaded engagement.
The leveling support portion has a plurality of wire insertion holes formed therein for inserting and fastening a reinforcing wire into the outer circumferential portion of the leveling support portion. The upper surface of the leveling support portion is flatly provided to measure the height of the concrete, It is preferable that the waterproof cover is provided to seal the boundary with the concrete as the water absorbs and expands.
In addition, it is preferable that a flow hole is formed in the penetrating guide portion so as to penetrate the heat insulating material cut in the vertical direction.
Through the above-mentioned solution, the composite insert device for concrete inlay of the present invention provides the following effects.
First, the support body portion is fixed to the formwork and includes a lifting body portion that is screwed and vertically moved. The leveling support portion of the lifting body portion can be used as a reference surface when the reinforcing bars are fixed and the upper surface is used as a reference surface. , A leveler, and a reinforcing spacer.
Secondly, the elevating body portion can use the upper surface of the leveling support portion as a concrete piling reference surface. Since the reinforcing bars are fixed and supported through the wire insertion holes, and the elevation body is raised and lowered in the support body portion, It is compatible with reinforcing spacer or leveler as a whole, so that one type of device can be used to carry out the entire construction, so that the convenience of the product can be improved as the construction design and preparation are simplified.
Third, the penetration guide part is coupled to the lower part of the support body part and guided to the inside of the heat insulation material, but can be separated and reused after the concrete is poured. Also, through the fixing nail provided at the lower part of the penetration guide part so as to protrude to the outside of the heat insulation material Since the anchor insertion point can be confirmed, it is possible to open accurately so as to minimize the loss in opening the insulation, thus improving the quality of the construction.
Fourthly, the support body part is formed with a fixing protrusion on the outer periphery, and is smoothly slid and inserted into the heat insulator through the slide part formed upwardly sloping downwardly of the fixing protrusion. After the inserting part is inserted into the insulator through the fastening part formed on the upper part of the fixing protrusion So that it is possible to firmly connect the heat insulating material to the lower portion of the concrete while improving the ease of construction and quality.
