Provides a rebar spacer structure for deck plates without. [Structure] One end of each of the reinforcing bar mounting portions made of two parallel steel bars is bent downward inward to form a slanted leg portion, and the other end of each reinforcing bar mounting portion is shifted downward inward. Reinforcing bar spacers, in which bent legs are formed at the same time and both legs are connected at the lower end by a connecting portion, are arranged at regular intervals in the longitudinal direction of the valley portion of the deck plate of the corrugated steel sheet, and Reinforcing bar spacer structure of the deck plate fitted to the formed bent inward jaw.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention is a rebar spacer for a deck plate for supporting rebars arranged in the valleys of the deck plate when concrete is placed on the deck plate of corrugated steel plate erected between beams to construct a composite floor. Regarding the structure.

[0002]

[Prior Art]

 Conventionally, in order to arrange reinforcing bars in the troughs of the deck plate, as shown in FIG. 5, a V-shaped structure having the troughs 2 of the deck plate 1 and the engaging portions 4 mounted on the top surfaces of the ridges 3 at the upper ends of both sides is used. A rebar 8 with a spacer having a lower bar 7 attached thereto is arranged on a holding portion 6 at the bottom of the spacer 5 having a shape of a bar. (As a prior art document, there is JP-A 1-256647).

Further, as shown in FIG. 6, a plurality of reinforcing bar fitting portions 11 are recessed in a single wire rod 10 at a pitch of the valley portions 2 in the valley portions 2 of the deck plate 1, and leg portions 12 are provided at both ends. A spacer 13 formed by bending is provided, the leg portion 12 is locked to the bottom end of the valley portion 2, and the reinforcing bar 14 is fitted to the reinforcing bar fitting portion 11. (As a prior art document, there is Japanese Utility Model Laid-Open No. 58-156815.)

By the way, in the former rebar 8 with a spacer, since the engaging portions 4 at both upper ends of the spacer 5 are simply placed on the top surface of the mountain portion 3 of the deck plate 1, a concrete is installed. It is often washed away and comes off. Also, the latter spacer 13 only locks the leg portion 12 to the bottom side end of the valley portion 2 of the deck plate 1. Therefore, if an external force is applied to the spacer 13 during work, it will fall or fall off. To do.

[0005]

[Problems to be solved by the device]

 Therefore, the present invention is a deck which does not fall off when the concrete is placed on the deck plate due to the flow of the rebar spacers, and does not fall or fall even if external force is applied during work. It is intended to provide a reinforcing bar spacer structure for the plate.

[0006]

[Means for Solving the Problems]

 The reinforcing bar spacer structure of the deck plate of the present invention for solving the above-mentioned problems is such that two ends of the reinforcing bar mounting portions made of two parallel steel bars are bent downward toward the inside to form inclined legs. , The other end of each reinforcing bar placing part is bent downward toward the inside to form a slanted leg part, and both leg parts are connected at the lower end by a connecting part, The deck plate is fitted into bent inward jaws formed on the inclined surface at regular intervals in the valley direction of the deck plate.

[0007]

[Action]

 In the above-described deck plate reinforcing bar spacer structure of the present invention, since the reinforcing bar spacer is fitted to the bending inward jaw of the valley inclined surface of the deck plate by utilizing the elasticity of the bent legs, The reinforcing bar spacer is firmly fixed to the valley. Therefore, when placing the reinforcing bar on the reinforcing bar mounting part of the reinforcing bar spacer, binding the reinforcing bar spacer with the iron wire and then placing concrete on the deck plate, the reinforcing bar spacer will not be washed away and will not come off. Even if external force is applied to the rebar spacer during rebar work, it will not fall or fall out, and the concrete cover thickness of the rebar can be properly secured.

[0008]

【Example】

 An embodiment of the reinforcing bar spacer structure of the deck plate of the present invention will be described with reference to the drawing. FIG. 1 shows a reinforcing bar spacer 15, which is a reinforcing bar mounting portion 16, 16 made of two parallel steel bars. One end of each of ′ is bent inwardly downward to form inclined legs 17, 17 ′, and the other end of each of the rebar mounting portions 16, 16 ′ is bent inward downward. The slanted leg portions 18 and 18 'are formed and the leg portions 18 and 18' are connected at their lower ends by a connecting portion 19 which is orthogonal to the reinforcing bar placing portions 16 and 16 '.

A plurality of the reinforcing bar spacers 15 are arranged at regular intervals in the longitudinal direction of the valley portion 21 of the deck plate 20 of the corrugated steel plate shown in FIG. 2, and as shown in FIG. It is fitted between the bending inward jaws 22 formed in the.

The reinforcing bar spacer structure of the deck plate of the embodiment configured as described above is a leg in which the reinforcing bar spacer 15 is bent on the bent inward jaw 22 of the inclined surface of the valley 21 of the deck plate 20. Since the portions 17, 17 ', 18 and 18' are fitted by utilizing the elasticity, the reinforcing bar spacer 15 is firmly fixed. Therefore, as shown in FIG. 4, the reinforcing bar 23 is placed in the left and right arcuate recesses 16a and 16'a of the reinforcing bar mounting portions 16 and 16 'of the reinforcing bar spacer 15, and after the reinforcing bar spacer 15 is bound with the reinforcing wire, When arranging the welded wire mesh 25 on the upper side and placing concrete 26 on the deck plate 20, the reinforcing bar spacer 15 is not washed away and the reinforcing bar 23 is not exposed. Further, during the rebar work, even if an external force is applied to the reinforcing bar spacer 15, the reinforcing bar spacer 15 does not fall over or fall out, and the cover thickness of the concrete 26 of the reinforcing bar 23 can be properly secured.

[0011]

[Effect of the device]

 As described above, according to the reinforcing bar spacer structure of the deck plate of the present invention, when the concrete is placed while holding the reinforcing bar in the valley portion of the deck plate, the reinforcing bar spacer does not flow away and does not come off. Even if external force is applied to it, it will not fall over or fall out, the concrete cover thickness of the reinforcing bar can be properly secured, and a highly accurate composite floor can be built.
