The present invention relates to the placing level spacer of concrete that allows to fix the thickness of concrete as well as the horizontal level by placing a reference point on the bottom of the formwork when placing concrete to the slab bottom of the building.

Conventionally, when forming a slab floor of a building, formwork is manufactured and a predetermined design value is assembled, and the inside is placed by supporting the reinforcing bars in the longitudinal and transverse directions, and then concrete pouring is started.

In the concrete pouring work on the formwork, the concrete was supplied from the one side to the predetermined thickness, and the concrete was supplied to the entire area. The concrete thickness and surface level were often dependent on the skill of the worker. The workbench formed with the horizontal length on both sides was mounted on the surface of the poured concrete, and the surface of the concrete was trimmed horizontally by moving back and forth or left and right.

Since the concrete placing and leveling state are based on the judgment of the worker's naked eyes, the job is based on the judgment by the naked eye. There was a case in which a thin form was formed, and a problem that the horizontal state of the entire floor was not formed evenly occurred.

If the height of the building is 10-30M / M thicker than the design value, the height of the building is increased by 100-300M / M based on the 10-story building, which is the source of administrative complaints. There was an economic problem that consumed more than the prescribed value.

Therefore, according to the present invention, in the construction of the slab of the building, the display member which can confirm the height of the concrete being poured, the elastic member which allows the display member to always return to the vertical position, and the elastic member provided with the display member Can be installed more precisely and precisely by the level spacer composed of the supporting members that securely support the reinforcing bars arranged vertically and horizontally to increase the solidification of concrete and at the same time, improve the quality of the building by precise construction. , Can prevent the waste of expenses.

Next, an embodiment of the present invention will be described in detail.

EXAMPLE

The support part 21 which contacts the bottom surface of the formwork 5 manufactured to form the slab layer 6 in the building is formed in a '+' shape to withstand the maximum load while forming the minimum area, and the support part ( The upper part of the base 21 is provided with a support part 21 for holding the reinforcing bar 7 at a predetermined design height and an assembly part 22 for stably fixing the display member 3 for recognizing the thickness of the concrete. The member 2 is formed.

Then, the graduation 31 is stamped on the surface to have a predetermined length, and the coil spring seat groove 32 is formed at the lower end to form the display member 3 standing vertically on the upper portion of the base member.

The display member 3 and the base member 2 are connected to each other, and an elastic member 4 is formed to retain elasticity so that the display member 3 always returns to its original position.

The level spacer 1 is formed by assembling the base member 2, the elastic member 4, and the display member 3.

In the above configuration, in order to minimize the contact area with the bottom surface of the formwork 5 on the bottom of the base member (2) is formed by protruding the supporting protrusions (213) in the middle and four sides of the base member (2) The support portion 21 forms the inlet hole 212 by removing the horizontal flesh portion except for the vertical rib of the support portion so that the concrete is filled into the inside. The support part 21 in which the inflow hole 212 is formed is like a window.

The level spacers 1 buried in the concrete should not be exposed to the outside of the solidified concrete, so that the support ball head 213 is formed in a shape occupying a small cross-sectional area to the bottom of the base member 2.

The forming of the supporting protrusions 213 in such a shape as to occupy a small cross-sectional area is to make the supporting protrusions 213 of the base member 2 small on the exposed slab surface when the formwork is removed from the concrete solidified state.

And the support portion 21 formed on the upper portion of the base member 2 is formed with a fixed seat 221 to support the reinforcement (7) so as not to be separated, the elastic member next to the fixed seat 221 of the support 221 The insertion hole 223 for fixing 4) to the base member 2 is dug out vertically.

The fixing seat 221 is formed by protruding the projection 222 to a predetermined position so that the reinforcing bar 7 does not leave.

The inner bottom of the fitting hole 223 forms a configuration in which the fitting piece 224 for fixing the resilient member 4 inserted therein protrudes.

In addition, the resilient member 4 is easily inserted into the fitting piece 224, and a recessed groove 225 is formed on the surface of the fitting piece 224 so that the coil of the resilient member 4 is inserted into the fitting piece 224 so as not to be easily removed after insertion. do.

The elastic member 4 inserted into the fitting hole 223 is preferably to use a coil spring having good elastic return.

The elastic member 4 is inserted into the fitting hole 223 and the lower end of the display member 3 of the base member 2 to connect the base member 2 and the display member 3.

According to the present invention having the above configuration, when the lower end of the display member 3 is inserted into the upper end of the elastic member 4, the winding shape of the coil spring of the elastic member 4 is inserted into the threaded shape of the display member 3. It is elastically coupled to the bottom like a screw coupling, the lower end of the elastic member 4 is also inserted into the fitting hole 223 of the base member 2 is coupled to the fitting piece 224 formed in the fitting hole 223, which is also elastic The winding shape formed in the coil spring of the member 4 forms a state in which the fitting piece 224 is inserted into the coil-shaped concave groove 225.

As such, when the elastic member 4 is coupled to the display member 3 and the base member 2, the elastic member 4 is contacted with the concave groove 225 by the insertion force and the frictional force due to the coiled shape. The outer diameter of the coil spring is inserted a little wider, but once inserted into the fitting piece 224 is retracted by the self-elasticity of the elastic member 4, when the elastic member 224 is pulled out in the unwinding direction of the coil spring Since the force is applied in the tightening direction of the coil spring in a state in which the elastic fitting piece () is tightened, the bottom piece of the fitting piece 224 and the display member 3 is tightened to achieve a state of not being released.

In the above configuration, the display member 3 may be coated with a fluorescent color and a luminous material on the surface in order to be easily seen by the operator's eyes, and formed of synthetic resin so that the cutting is properly made to display the concrete height.

And the support portion 21 is perpendicular to the upper surface of the support portion 21 with a through hole 214 for fitting the nail 9, which is used for the purpose of preventing the level spacer 1 from flowing on the surface of the formwork (5). Formed through.

When the level spacer 1 as described above is installed in the formwork floor of the building in several places, the reinforcing bar 7 installed in the longitudinal direction from the formwork is inserted into the fixing seat 221 of the level spacer 1 support 21. 7) is a state of being lifted to a predetermined height from the bottom of the formwork 5 due to the height of the fixing seat 221, the installation state of the reinforcing bar 7 is stabilized.

In the state where the level spacer 1 supports the reinforcing bar 7, the display member 3 coupled to the assembly unit 22 forms a vertical state with respect to the bottom of the formwork 5.

Then, the concrete placing height is set in advance and displayed on the display member 3 of the level spacer 1, and the marked portion is cut.

When the level spacers 1 cut at the height of the concrete are placed on the bottom of the formwork 5, the display member 3 standing vertically at the level spacers 1 finally indicates the surface height of the slab layer 6. In this case, the worker senses the height to be already worked before the concrete is poured.

Therefore, in the subsequent concrete pouring work, if the worker only fills the concrete up to the top height of the display member 3, the slab layer 6 not only forms a uniform thickness in the formwork 5, but also the bottom of the slab layer 6. Shave is formed evenly. Because when the concrete is supplied over the design value during the operation, the display member 3 is not buried, so when the floor is selected so that the display member 3 is visible, the bottom of the slab layer 6 is not uneven and has a flat surface. do.

In this way, the thickness of the slab layer 6 and the surface state of the bottom are evenly formed, and the concrete flowing into the inlet hole 212 formed in the support part 21 of the level spacer 1 is formed in the formwork 5 and the level spacer 1. The gap between the gaps is filled to stabilize the pouring state of the concrete and the fixed state of the level spacer 1.

In particular, the protrusions 213 protruding to the bottom of the support portion 21 form a space through which the concrete can flow between the formwork 5 and the level spacers 1, so that the concrete is uniform to the floor where the level spacers 1 are located. The level spacer 1 is not visible on the bottom surface of the slab layer 6 that is exposed after the formwork 5 is removed.

In the concrete pouring work using the level spacer 1, the self-entry worker enters the formwork 5, grabs the concrete supply hose from which the concrete is discharged, and moves the formwork 5 inside. If you step on it without finding it.

In this case, the display member 3 installed perpendicularly to the level spacer 1 may be bent by the operator's foot, but if the operator releases the foot from the cover member 3, the restoring force of the resilient member 4 may occur again. The display member 3 of the level spacer 1 is always kept in a vertical state by performing a vertical return to the initial position.

As the worker supplies the concrete in a state in which the worker supplies the height of the concrete in advance, the worker has an effect of preventing the slab thickness from being formed over the prescribed value by mistake of excessively supplying the concrete.

In addition, since the worker grasps the supply height before supplying and supplies the concrete, the thickness of the slab layer is uniformly formed in the whole building, which has the advantage of unifying the building standard, and prevents waste of concrete and consequent waste of construction cost. There is an advantage.

Example 2

The resilient member 4 inserted into the fitting hole 223 formed in the support portion 21 of the level spacer 1 provided in the formwork 5 has a long length, and is provided at the tip of the resilient member 4. The lower end of the coupling member 3 to be joined is formed by a nut 32 fixed to the elastic member 4, and the nut 32 has a fastening element 33 having a predetermined length inserted therein, and the fastening element 33. ) Is made of a fixing nut 34 to adjust the insertion length of the screw, the fixing hole 221 of one or more diameters different from each other so that the reinforcing bar other than the scraping hole is fixed around the fitting hole 223 of the support portion 21 221A is formed in an opposite position.

According to the above configuration, the display member 3 rotates the fastening element 33 to the fixing nut 34 of the resilient member 32 to fit the tip of the fastening element to the set height of the concrete, and the fastening element 33. When the fixing nut 32 is inserted into close contact with the upper surface of the nut 34, the fastening element 33 is fixed to the nut 32 to indicate the height of the concrete to work.

The level spacer 1 is the same as the operation and effect of the above-described embodiment.
