Abstract

The present invention relates to a sectional building panel, wherein one or more outward protrusions are formed on the inside thereof and coupling assists are formed on the inside and outside of the same. Inner plates with metal laths attached to the outward protrusions are symmetrically disposed to form an insertion protrusion part at the upper side thereof and an insertion recess at the lower side thereof. An insulating member having coupling holes is formed at the center of the inner space between the inner plates and outer plates, wherein bolt connections are fitted and fixed in the coupling holes formed in the insulating member, and both ends of the bolt connections are fitted and coupled to the through-holes formed in the inner and outer plates. Accordingly, the sectional building panel is constructed on the inner and outer walls of a building and on a retaining wall which supports large loads so as to provide robustness and load-bearing capacity for supporting a structure. In addition, according to the present invention, after a wall is formed by successively assembling sectional building panels at the construction site, the partitioned inner space of the sectional building panels is filled with cement mortar in a single process, thereby constructing crack-resistant inner and outer walls and ensuring stability in constructing a retaining wall.

Description

Prefabricated Building Panels and Wall Blocks

The present invention relates to a prefabricated building panel, and more particularly, to form an inner and an outer plate body inside and outside of a heat insulating material in which a plurality of binding holes are formed for the inside, outside wall or retaining wall construction of the building, and the heat insulating material and the inside and outside plate bodies. It is related to the prefabricated building panel that is installed on the inner and outer walls of the building and the retaining wall subjected to a large load by simply assembling and connecting the panel and the panel when assembling the wall.

The present invention also relates to a wall block which can be stacked by inserting the insertion protrusion into the insertion groove in a continuous manner.

In general, the prefabricated panel is configured by filling the heat insulating material inside to correspond to the symmetrical plate body on both sides in order to configure the inner and outer walls of the building. Such a prefabricated panel is also called a sandwich panel, it is light in weight and can be easily assembled. Such a prefabricated panel is used as an exterior wall of a structure such as a building or a storage warehouse because of excellent heat insulation as well as moisture prevention and sound insulation.

Figure 1 shows a coupling structure of a conventional prefabricated panel was proposed in the Republic of Korea Utility Model Registration (2004.01.16 notification, registered 20-0338697) as a preliminary design, look at its configuration formed on the inside and outside at regular intervals The heat insulating material 20, 20 'is filled in the metal outer plates 10 and 10' which are made of metal, and the coupling parts 30 and the coupling grooves 40 having the

close contact parts

30b and 40b are respectively formed at both ends. The intermediate point of the coupling protrusion 30 is formed in the trapezoidal groove portion (30a) by a predetermined width inwardly to round both sides of the coupling protrusion 30 in a semi-circular shape, the middle of the coupling groove portion 40 At this point, it is proposed as a prefabricated panel 'which is formed by engaging the protrusion 40a so as to fit into the groove 30a formed in the coupling protrusion 30. The prefabricated panel of such a structure could be economically and easily installed in the interior and exterior walls of the building, but in the construction of the interior, exterior wall or retaining wall proposed by the present invention, the structure is constructed only by insulated and filled with the metal outer plate. Not only does not hold firmly, there was a problem that can not withstand the weight of a large external force.

On the other hand, in constructing a wall, a prefabricated wall having a structure in which a heat insulating material (Styrofoam) is filled inside and a thin metal steel sheet is attached to both sides thereof is formed to build a structure or used as an outer wall when constructing a retaining wall. That is, the conventional wall forms an insertion portion on one side of the panel, forms a protrusion on the other side of the panel, and then inserts the protrusion of another panel on one panel insertion part to sequentially assemble the wall. However, the method of assembling the wall using the conventional prefabricated panel is easy to assemble, but the insulation formed by filling the inside of the front metal plate and the rear metal plate alone does not firmly support the structure, and when constructing the retaining wall. There was a problem that can not bear the weight of a large external force.

In addition, the registered patent publication (2008.08.26 publication, 10-0854578 registration) is provided with a pile insertion groove continuous circular pipe shape by a predetermined depth so as to enable rotation, and is prescribed in the normal direction from the outer surface of the pile insertion groove. The buried pile-shaped buried pile is formed on the ground by using a rotatable holder having a length corresponding to two side by side at a predetermined interval and including a wall block insertion groove which is continuous by twice the depth of the file insertion groove. After the purchase, two rotary holders per one pile are symmetrically stacked in the vertical direction and connected by sliding fitting along the outer surface of the pile, and two continuous pieces are installed at predetermined intervals in the longitudinal direction of the wall. The rotation of the first embedded pile is rotated by rotating each of the rotary holders fitted in the pile about the cross-sectional center of the pile insertion groove of the embedded pile. The type wall mount slot is adjusted so that the wall block insertion groove of the second buried pile can face the wall block insertion groove of the second buried pile so that the precast wall block slides up and down along the two wall block insertion grooves facing each other. It is proposed to install the method, characterized in that the insertion is inserted. In the installation method with the structure of the wall block and the fixing rod and the embedded pile, there is an advantage in that it is possible to simply complete the wall by continuously stacking the integrated wall block by omitting the conventional site-casting process of the reinforced concrete structure.

However, the conventional installation method of the wall block and the structure of each fixture and the buried pile is a complicated process of embedding the buried pile in the field, and the assembly of each of the fixtures into the buried pile as well as the wall block. The combined configuration of the wall was weak and the loadability was only applicable to the wall construction of the structure. In addition, the wall block can be bent when laminated by assembling the wall block and the wall structure of the same structure continuously, even if the finishing material between the wall block and the block block there is a problem that the waterproofness of the wall is inferior.
