Abstract
The stiff stand according to one aspect of the present invention includes a main body having one side opened, a spreading plate accommodated in the main body and vertically lifted and formed at least one of the main body and extending to an upper portion of the main body, And a laser director for receiving the laser beam irradiated in the horizontal direction in the leveler may be provided on the front side.
Description
The present invention relates to a stiff stand, and more particularly, to a stiff stand capable of combining a staff for measuring a level, a plurality of bodies separated from each other, The present invention relates to a stiff stand capable of marking without movement.
Generally, in order to make a horizontal plane with respect to a construction floor in a construction site or the like, a horizontal level is measured. In this way, a measurement level and a staff are used for horizontal level measurement.
That is, the measurement level unit irradiates the laser in one direction or 360 degrees, and the laser is irradiated in the horizontal direction, thereby being a reference for adjusting the horizontal level of the construction floor.
A conventional method of measuring a horizontal level using a measurement level and a staff is as follows. An operator uses a laser beam irradiated in a horizontal direction on a measurement level machine supported by a tripod on a floor, And the distance from the laser beam irradiated from the measurement level device is measured in a state in which the staff is leaned or brought close to the mold for forming the reinforcing bar structure or the wall or the retaining wall. The marker is used to mark the scale line or the leader line on the corresponding reinforcing structure or form, and concrete is laid up to the leader line to complete the construction floor.
As described above, the spacing distance is determined in advance by using the laser and the staff of the measurement level period irradiated in the horizontal direction, and the leader line is displayed on the reinforcing structure or the die of the portion indicating the predetermined spacing distance.
However, since the reinforcing structure or the formwork is complicatedly installed at the construction site, it is difficult to precisely match the laser irradiated from the measurement level device to the scale portion of the staff, and the leader line is correctly displayed on the reinforcing structure or die coming to the measured position There is a problem that it is very difficult to do.
In particular, when a marker is inserted between the reinforcing structures, a leader line is not displayed properly. Therefore, there is a problem that an error occurs between a plurality of leader lines.
Since usually the construction site of the bar that is constructed in the
This is because the laser beam at the measurement level has a straightness, for example, when there is a reinforcing structure or a mold at the front of the position to be measured, the laser beam comes into contact with the reinforcing structure or the mold.
Such a problem results in that the horizontal level measurement can not be precisely performed, and consequently, even if the concrete is laid, the floor of the construction can not be leveled at all.
In order to display the leader line, the operator must hold the staff member and the other worker must mark the leader line with the marker corresponding to the specific scale of the staff member. Therefore, the worker must move together to display the leader line, And it is required to put markers between complex reinforcing structures and display them. Therefore, it takes a lot of time and effort to display the leader lines, which causes a delay in the construction period.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a stiff stand which can extend a height of a stiff stand to a great extent.
It is still another object of the present invention to provide a star stand which is provided with a marking pen whose angle is variable on a star stand so that marking can be performed on the wall without being disturbed by the obstacle.
In order to achieve the above object, according to one aspect of the present invention, there is provided a stiff stand, comprising: a main body having one side opened; a main body which is accommodated in the main body and vertically moves up and down, And a laser director which is coupled to an upper portion of the extension plate and receives laser beams irradiated in a horizontal direction in a leveling unit.
Wherein the main body has a scale portion marked with a scale on an outer side surface of the outer side and accommodating the extension plate therein and a lifting protrusion provided on the inner side of the scale portion and guiding the lifting plate up and down, And a supporting member which is provided at a lower end of the housing to allow the main body to be supported on the floor, a conveying rod formed to penetrate through the supporting member and extending upward from the inside of the accommodating portion, And a conveying unit having a conveying plate for ascending and descending the conveying unit.
Wherein the extension plate includes at least one extension portion having one side inserted into a receiving portion provided inside the main body and coupled to an elevating projection provided inside the receiving portion and at least one extending portion passing through the extending portion, A fixing part for lifting and fixing the extension part to the upper side by the guide part and a fixing part for fixing the extension part to the lower part of the extension part and having one side inserted into the accommodation part A marking pen, and an engaging portion for rotating the marking pen so that the angle of the marking pen varies vertically and horizontally.
Wherein the engaging portion includes a guide plate having a receiving space formed therein having a stepped portion for accommodating at least one guide rod having a different diameter on the inner side, an insertion protrusion coupled between the side wall of the receiving space and the guide rod, A magnet provided at a lower end of the protrusion and having an engaging plate having a engaging hole to which the marking pen is engaged; a magnet fixed by a step of the accommodating space to allow the engaging plate to be detachable from the guide plate; And a separation preventing plate formed as a semicircle for preventing the guide rod from moving in the accommodating space.
Wherein the marking pen includes a hinge portion having a rotation protrusion inserted into the coupling hole, a marker portion horizontally moving through both inner side surfaces of the hinge portion and having a marker pen on the front surface thereof, And a retractable portion accommodating the marker portion at the other end of the pen and providing elasticity of the marker portion.
According to the star stand according to the present invention, since a plurality of extension portions provided with a fixing device in the main body can move up and down, the level can be easily measured.
Further, a joining member capable of joining the marking pen is provided at the lower end of the extended portion, and the joining member can be rotated by the hinge portion to mark the wall.
