Block out construction method for apparatus base

The present invention relates to a device-based construction method, and more particularly to a device-based construction method that can be fixed to the foundation block fixing bolts fastened to the base block more accurately and precisely.

In general, in order to install a device (device) in a specific place such as slab, wall, ceiling, etc., the foundation concrete and anchor bolts should be installed at the position where the device is to be fixed, and then the fastening formed at the fastening end of the device. The anchor bolt is inserted into the hole (or the fastening hole of the fastening mechanism) to be fixed.

Anchor bolts are commonly used in the construction and civil engineering sectors to connect structures such as steel structures or wooden pillars or steel girder bridges to the foundation of concrete or reinforced concrete.

These anchor bolts are also widely used to fix various devices (such as the main body of the device or peripheral parts of the device such as pipes), and by fastening the fastening ends of the device with anchor bolts at a plurality of fastening points, Prevent the device from moving.

At this time, the anchor bolt alone is difficult to obtain a sufficient rigidity, so the anchor bolt (hereinafter referred to as fixing bolt) is fixed to the concrete foundation block embedded with reinforcing bars and then fastened with the device.

In addition, since the position of the fastening hole is predetermined at the fastening end (or fastening mechanism) of the device, what should be done by exactly matching the position of each bolt with the corresponding fastening hole position of the device when pre-installing the fixing bolt before installation of the device. More important.

In the conventional case, when installing the foundation concrete in the place where the equipment, such as slab, wall, ceiling, will be installed together with the fixing bolt and the foundation block, the reinforcement of the cast iron reinforcement embedded in the foundation block, the formwork for forming the foundation block This will involve a block out construction process that requires installation and concrete placement.

Fig. 1 is a plan view showing a typical construction state of a block base for a device foundation having a fixing bolt fixed thereto, and Fig. 2 is a typical construction sectional view of a block out for a device foundation with a fixing bolt fixed thereto, which is the line of Fig. 1. A cross section taken along 'A-A'.

Here, reference numeral 10 denotes the foundation concrete, reference numeral 11 denotes the concrete reinforcement embedded in the foundation concrete 10, reference numeral 21 is a connection construction to be embedded in the concrete and the foundation concrete 10 of the foundation block 22 Indicates a cast iron.

As shown in the figure, while constructing the foundation concrete 10 in the place where the equipment, such as slab, wall, ceiling, and the like to construct the concrete foundation block 22 of the protruding structure together, grooves (the upper surface of the foundation block 22) After the fixing bolt 25 is inserted into the 23, the non-shrink concrete is poured into the groove 23 to fix the fixing bolt 25.

Since the fixing bolt 25 fixed as described above has a structure that protrudes and extends from the base block 22, the fixing bolt 25 is inserted into the corresponding fastening hole of the device, and then the nut is fastened to the fixing bolt. It will be completely fixed so that the device does not move.

The base block 22 and the fixing bolt 25 of the block-out for the device base is installed in accordance with the number of fastening holes of the device, by fastening at the same time in a plurality of block-out position can be more securely fixed to the device. Will be.

3 is a process diagram showing the basic construction process of the device according to the prior art, a device foundation, that is, a fixing bolt 25 for fixing the device, a concrete foundation block 22 to which the fixing bolt 25 is fixed, and The construction process of the block out including the cast reinforcing bar 21 to be built into the foundation block 22 is shown divided into three stages.

That is, the construction of the main reinforcing bar 21 and the concrete foundation block 22, the insertion of the fixing bolt 25, can be proceeded to the process of placing the non-contraction concrete 24. Is the same as
