Description

{Base for prefabricated column}

In the present invention, bolts are assembled to the joint socket and the steel material in the state where the pre-assembling post is located inside the engaging socket provided on the base plate, and the pre-assembling post is fixed to the base, thereby greatly improving the workability, safety, economical efficiency and construction precision This is for the main part for installing the pre-assembled column.

The pre-assembly column comprising the steel material and the lattice material shown in FIG. 1 has advantages such as shortening of air and improvement of workability, and it is widely expected to be used as a steel-concrete composite member (Patent No. 10-1490748) .

The conventional pre-assembly column as shown in FIG. 1 was formed by welding a steel plate to a base plate.

However, there is a disadvantage that the field welding process is affected by the weather conditions and there is a possibility of welding failure due to a large variation in quality depending on workers.

In addition, although the pre-assembled column consisting of a steel plate and a lattice material can be assembled by bolts in the factory, it is necessary to weld the steel plate as a whole because welding is required for joining to the foundation in the field.

In other words, the steel is used as rolled steel for welding structure such as SM490. SM490 is more than 10% lower than ordinary high strength steel SS540 which is similar in price.

In addition, it is necessary to sequentially weld the four-shaped steel material to the corner of the column at the upper part of the base plate. In this case, it is difficult to fix the position of the shaped steel material, thereby making it difficult to perform precise work.

In order to solve the above-mentioned problems, it is an object of the present invention to provide a main part for mounting a pre-assembly column, which requires no welding process to a base plate during pre-assembly column construction, thereby greatly improving workability and safety.

The present invention is to provide a main part for installing a pre-assembled column which can be precisely installed due to the positional fixation of a steel material, since it is not necessary to use welding steel as a pre-assembled column shaped steel material.

According to another aspect of the present invention, there is provided a method for installing a pre-assembly column on a base upper surface, in which a steel material is disposed at four corners in forming a steel-concrete composite member and an outer side of a neighboring steel material is connected to a plurality of lattice materials A base plate provided on the base surface; An anchoring member coupled to the bottom of the base plate and fixed within the base; The base plate is formed with four rectangular shaped bonding plates so as to form a quadrangle, and a space is formed therein. In the bonding plate, a coupling hole for bolt connection with the shaped steel material is formed at a position corresponding to the shaped steel material, A joint socket in which a flow hole is formed so that concrete can flow inside and outside; And a pair of legs, which are bent in a planar shape, and a pair of which are coupled to both sides of the respective legs, respectively, and extends downwardly, and the lower end is bent or curved outwardly to be bent, A guide member which is composed of a fixing member and is detachably coupled to one of the corners of the coupling socket to guide any one of the shaped members of the pre-assembly column and is removed after the insertion of the pre-assembly column; The present invention provides a main part for installing a pre-assembled column.

According to another preferred embodiment of the present invention, the joining plate is provided with a pressing portion protruding inwardly to be in close contact with the outside of the steel material of the pre-assembly column, and the joining hole is formed in the pressing portion. Provide installation parts for installation.

According to the present invention, the coupling socket is provided on the upper portion of the base plate so that the pre-assembly column is positioned inside the coupling socket when the pre-assembly column is removed. By thus positioning the pre-assembly column at the first position, It can be assembled to fix the pre-assembly column to the foundation.

Therefore, it is very easy to fix the pre-assembly column and it is possible to precise construction.

In addition, the process of field welding the pre-assembled column to the base plate can be omitted, which improves the safety, and it is not necessary to use the welding steel as the pre-assembled column steel.
