Description

Reinforcing spacer for deck plate {omitted}

The present invention relates to a reinforcing spacer for a deck plate, and more particularly, to a reinforcing spacer for a deck plate which enables a reinforcing spacer for fixing a reinforcing bar to be stuck to a deck plate of a building site to be stably fixed to a deck plate .

The deck plate used in the steel frame structure is used as a tensile material, which is advantageous because it can reduce the amount of reinforcing steel and concrete.

A reinforcing spacer is used to place the reinforcing bars on the deck plate. As a conventional technique, a reinforcing spacer for a deck plate of the registered utility model No. 20-0231271 will be described as an example.

As shown in Fig. 1, the spacer 200 has, in the form of a claw-leg, a hook-and-loop portion 221 forming an insertion hole B (223) such that a flange of the deck plate is inserted between the claw- Preventing bridges 222 which are bent at the leg portions and which are bent outwardly of the vertical webs of the deck plate while forming flanges of the deck plates, respectively, extending to the lower portions where the engagement curved portions 221 are formed, A coupling leg 220 made of synthetic resin or metal having elasticity; And an insertion groove 211 formed integrally on the upper surface of the coupling leg 220 and formed with an insertion hole A 213 for inserting and fixing a reinforcing bar or a welded wire mesh into an upper portion of the insertion groove 211, And a reinforcing rod insertion portion 210 made of synthetic resin or a metal material having elasticity, which is composed of a locking protrusion 212 which is extended and formed at both ends.

Accordingly, the coupling legs 220 of the spacer 200 are inserted into the flange of the deck plate at regular intervals to fix the reinforcing bars laid on the reinforcing bars 210, .

However, such a spacer 200 has a disadvantage in that it is inclined forward and backward when it is not correctly inserted on the flange. Even if the spacer 200 is correctly inserted into the flange, the spacer 200 can slip and move in the longitudinal direction on the flange, There is a problem that it can not be done.

That is, since the spacers 200 can be separated from the fixed position on the deck plate, the equal spacing can not be maintained and there is a disadvantage that the reinforcing bars can not be positioned at the correct positions due to tilting. It is holding.

Accordingly, the present invention provides a reinforcing spacer for a deck plate, which is capable of maintaining a stable position on a flange of a deck plate and preventing inclination in a forward and backward direction, in order to solve the conventional problems.

In the deck plate reinforcing spacer according to the present invention,

A reinforcing bar inserting portion having an insertion hole in which an upper side is opened to insert a reinforcing bar and an elastic pressing piece that presses an elastic force to prevent the detachment of the reinforcing bar inserted into the insertion hole;

A pair of legs spaced apart from each other by a flange spacing of the deck plate and protruding downward from the reinforcing bar insertion portion and having fixing means for fixing to the vertical web of the flange at the lower end;

And a support portion protruding outward in the horizontal direction from the lower end of the reinforcing bar insertion portion to support the spacer by contacting the upper end surface of the flange and formed in the front and rear direction of the reinforcing bar insertion portion.

The present invention is not only stably fixed to the flange of the deck plate by the leg portion having hooks but also prevented from tipping in the forward and backward directions by the support portion, thereby stably maintaining the state of the reinforcement of the reinforcing bars, .

2 is a view showing a structure of a reinforcing spacer according to the present invention.
Fig. 3 is a view showing a frontal structure of the present invention. Fig.
4 is a view showing a state in which the present invention is mounted on a deck plate and reinforcing bars are laid.
5 and 6 are views showing another example of the present invention.

The present invention thus constructed will be described in detail with reference to the accompanying drawings.

FIG. 2 is a view showing a perspective structure of the present invention. FIG. 3 is a view showing a front structure, and is largely composed of a reinforcing bar insertion portion 130, a pair of leg portions 110 and 120, and a support portion 140.

A pair of insertion holes 131 and 132 for fixing and inserting reinforcing bars are formed in the upper side of the reinforcing bar insertion portion 130. The upper side of the insertion holes 131 and 132 is opened and the reinforcing bar is inserted inward And the elastic pressing pieces 133 and 134 are formed in the insertion holes 131 and 132 to prevent the detachment of the reinforcing bar.

The elastic pressing members 133 and 134 are bent and positioned inward of the insertion holes 131 and 132 from the open upper ends of the insertion holes 131 and 132 so that the inserted reinforcing bars are elastically pressed so as not to be separated from the insertion holes 131 and 132 will be.

The structures of the insertion holes 131 and 132 and the elastic pressing pieces 133 and 134 are already disclosed in the registration room registration No. 20-0203624 and the registered application package 20-0474654 already registered by the present applicant,

Meanwhile, a pair of legs 110 and 120 protruding downward are integrally formed at a lower side of the reinforcing bar insertion portion 130 while maintaining a gap to be inserted into the flange of the deck plate. Hooks 111 and 121, which are fastening means in the flange direction, are formed at the lower ends of the legs 110 and 120, respectively, so that they are hooked on the hooks formed on the vertical webs of the flanges.

A supporting part 140 protruding outward is formed at a lower end of the reinforcing bar insertion part 130, that is, between the reinforcing bar inserting part 130 and the leg parts 110 and 120, And is formed in the front-rear direction of the reinforcing bar insertion portion 130, respectively.

Although not shown in the drawings, a bolt or a screw may be inserted into the support portion 140 to fix the spacer 100 to the flange of the deck plate. .

FIG. 4 is a view showing a state where the present invention is mounted on a detent plate and a reinforcing bar is laid, and the tech plate 400 is'

And flange 410 protruding upward in the form of a

vertical protrusion

430 and 431 protruding outward from the

vertical webs

420 and 421 on both sides of the flange 410.

The flanges 410 are inserted into the space between the legs 110 and 120 of the spacer 100 of the present invention and the hooks 111 and 121 are hooked on the hooks 430 and 431 of the vertical webs 420 and 421, respectively, ) From detaching from the detent plate (400).

After the spacer 100 is installed, the spacer 100 is fixed to the flange 410 by fastening a bolt or a screw through a fastening hole formed in the support portion 140 to prevent the flange 410 from moving and tilting in the front- .

When the bolts or the screws are not fastened, the spacer 100 supports the tilting of the spacer 100 in the forward and backward direction by the support portion 140, thereby preventing the position of the reinforced bar 500 from being changed.

5 and 6 are views showing another example of the present invention. The supporting part 140 is not a semicircular shape as shown in FIG. 2 but a flat plate shape in the form of a square, and the reinforcing bar insertion part 130 and the leg parts 110, As shown in FIG.

This is supported on the upper side of the flange 410 with a wider area so as to prevent movement and tilting in the forward and backward directions.

Instead of the hooks 111 and 121 which are fastening means formed on the legs 110 and 120, protrusions 112 and 122 protruding in the form of semicircular protrusions inwardly may be formed.

The protrusions 112 and 122 have a rounded shape from the upper side to the lower side and are formed to be elongated in the width direction of the legs 110 and 120 so that they can be respectively caught by the engagement protrusions 430 and 431 of the vertical webs 420 and 421.

As described above, the shape of the support portion 140 may have various shapes, and the structure of the fixing means having the structure of the hooks 111, 121 or the protrusions 112, 122 may be formed in various shapes other than those described in the present invention.
