Description

DETAILED DESCRIPTION OF THE INVENTION The purpose of the present invention is to provide a concrete floor surface leveling system that aims to enable the theoretically most accurate level guide method to be easily and accurately constructed at an actual work site. This relates to a guide frame for construction.

In conventional level guide construction methods for concrete floor construction, guide devices such as guide rails and wires are installed horizontally (level) on the base of the floor construction in advance, or guide rails and wires are installed in advance. devices (e.g. stops, anchors or supports) had to be fixedly installed, which required a great deal of time.

In addition, the equipment may be damaged during concrete pouring work, it may be buried in the concrete and become unknown, or it may become unusable due to a change in the concrete pouring direction due to an obstacle, or other problems. They were almost unable to respond to the various problems that occurred on site.

In this way, the level guide construction method is theoretically the most effective, but in terms of work, it is considered an empty area, and the level is still set only at points, and construction is done based on the worker's intuition. The accuracy was poor, and there was a drawback that no improvement in work efficiency could be expected compared to the current situation.

This invention was invented to eliminate these conventional drawbacks.

An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a long main frame made of magnetic material. Mounting plates 2 and 3 are attached to the lower ends of the main frame 1, respectively.
A level guide 4 made of piano wire, bar steel, etc. is installed parallel to the main frame 1 between 30 and 30.

The mounting plate 2Vc located at the tip of the main frame 1 has a first threaded cylinder 5 mounted in the vertical direction, and a first shaft rod 6 is screwed onto the first threaded cylinder 5, so that it can be rotated to the top of the first shaft rod 6. Attach the first pointer 7 to.

The first pointer 7 indicates the graduations of a first scale 8 established approximately at the tip of the main frame.

Further, a first leveler 9 is installed in the longitudinal direction on the main frame 1 close to the first scale 8 to measure the horizontal level of the main frame itself.

At the other end of the main frame 1, 2.3 screws 11.12 are installed in the vertical direction at substantially both ends of the frame 10 whose central portion is fixed so as to form a substantially T-shape in the horizontal direction. 3
The level unit 20 is formed by screwing the second and third shaft rods 13 and 14 into the threaded cylinders 11 and 12, respectively.

A second pointer 15 is rotatably attached to the upper part of one of the second shaft rods 13, and indicates a scale provided on the surface of a second scale 16 established at the upper part of one end of the frame 10.

Reference numeral 17 denotes a second plate attached in the longitudinal direction of the center plane of the frame 10.
This is a spirit level and is used to measure the level of the frame itself.

18 is a rope attached to the lower side of the main frame 1 for lifting the main frame.

Reference numeral 21 is a level display bar having a stand 22 formed of a magnet on its lower surface and having a scale on its surface.

25 is a leveling ruler.

To explain how to use this device, a pair of level units) 20.
20, and while looking at the second level 17, turn the 2nd and 3rd axis rods 1.
3 and 14 to level the frame 10, and then, while looking at the first leveler 9, rotate the first shaft 6 to level the main frame 1.

When the main frame 1 becomes horizontal, the level guide 4 also becomes horizontal.

Next, the level display bar 21 is sucked onto the main frame 1, and the scale marked on the surface of the level display bar 21 is viewed using a known leveling machine.

In this case, since the level point 23 on the level display bar is somewhat higher or lower than the standard of the leveling machine, the person measuring the leveling machine will tell you the difference.

In this case, for example, if the level point 23 is two scales higher than the reference, the second shaft 13 is first rotated to lower the frame 10 and the second pointer 15 is lowered by two scales on the second scale 16.

Then, the second shaft 13 side of the frame 10 naturally tilts downward, so the third shaft 14 is rotated while looking at the second level 17 to correct the frame 10 to be horizontal again.

Furthermore, if one end of the main frame, the frame 10 side, goes down,
Naturally, the main frame 1 is tilted, so the main frame 1 is adjusted to be horizontal again by rotating the first shaft 6 while looking at the first leveler 9.

In this way, as shown in Fig. 4, after aligning the level points of the pair of level units 20° and 200 with the standards to obtain horizontality, ready-mixed concrete is placed on this concrete pouring surface, and then the pair of level units If a leveling ruler 25 is placed on the guide 4.4 and the worker holds this leveling ruler 25 in his/her hand and moves it in the direction of the arrow, the upper surface of the poured concrete can be leveled horizontally.

After leveling, hold the rope 18 and pull up the main frame 1 on the first shaft 6 side, then lift the leveling unit 20 and install it again at another location, repeating this process to continue concrete pouring work. This is done by doing so.

If there is an obstacle between the level measuring device (not shown) and the level display bar 21, move the level display bar 21 left and right on the main frame 1 and move the base 22 to the main frame 1. Measurement can be carried out by adsorbing it to an arbitrary location.

In addition, at the site of concrete pouring work.

Concreting work can be carried out efficiently with at least two (usually three).

Further, the first scale 8 is auxiliary and may be omitted.

As described above, this invention has a tripod-type integral frame structure and the level guide is unitized, so there is no need for any pre-installation equipment, and the guideline can be freely set at any location, and the guide direction is fixed. This feature allows it to be used freely depending on the location of obstacles at the work site.
