Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a concrete treatment member for construction, and more particularly to a concrete flow stop member for a deck plate used as a floor material.

[0002]

[Prior art]

 In the case of building a concrete floored building, if the floor material is steel deck plate 1 as shown in Fig. 9, deck plates 1 are laid on each floor and the beams are spread as shown in Fig. 10. After being fixed to the material 2 by welding 3 etc., the concrete 4 is poured onto the deck plate 1 to a predetermined thickness to form the concrete floor surface 5. However, since this floor forming work is usually a work process performed before the outer wall 6 is constructed, it must be poured onto the deck plate unless some concrete blocking means is provided at the edge of the deck plate 1. The concrete will flow out of the deck plate in all directions. Therefore, regarding this flow stop means, there is usually no clear instruction or special description in the design drawings, and each company sells many kinds of deck plates in terms of plate thickness and model etc. At present, there is no indication as to the detents to be used. For this reason, the flow stop is usually constructed according to the management procedures of each construction company. However, the following two methods are generally adopted as the flow stopping means. The first method is a method that is generally widely adopted. On the side surface of the deck plate 1, there is provided a concrete stop plate 7 made of an iron plate having a height almost the same as the thickness of concrete poured onto the deck plate. This is a method of directly welding and constituting a flow stop means, and even after concrete is dried, the stop plate 7 is not removed and is simply embedded in the concrete. The second method is a simplification of the first method, in which a wooden stopper plate 7 is used instead of the concrete stopper plate 7 made of an iron plate. First, a pressing member made of an iron round bar or the like is used. 8 is welded onto the beam 2 and a wooden stop plate 7 is sandwiched between it and the deck plate 1 to form a flow stop means, and the stop plate 7 alone is removed or removed after the concrete dries. It is a method of embedding it in concrete as it is.

In the first of these methods, an iron plate is cut into a predetermined size to form a concrete stop plate, which is placed around the entire circumference of the deck plate and can withstand the pressure of flowing concrete. Since it is necessary to weld the stop plate to the deck plate as described above, the material and the cutting work are very expensive, and even in the welding work performed on site, the setup time and welding work time for that are required. It requires a lot of man-hours and labor. In addition, since the adhesion of concrete deteriorates, this iron plate is not usually coated with rust prevention. For this reason, if it continues to rain before the completion of construction of roofs, outer walls, etc., rust will occur on the iron plate, and the rust will seep out to the end faces of the concrete, and in some cases brown water will flow downstairs. There was a flaw. Also, in the second method, if the plate material is removed, concrete will flow downstairs from the gap between the lower surfaces of the cut surfaces of the deck plate when concrete is poured into the space between the outer wall and the outer wall. . In order to solve such a problem, a member for closing the end portion of the deck plate is commercially available as well as the deck plate. However, due to the high unit cost of the members, the troublesome installation work, and the use of such members, the flow stop plate must be used, etc., and is currently not used unless otherwise specified. . Therefore, in order to solve this problem, an iron plate having the same shape as the gap on the lower surface of the deck plate is used to form a member for closing this gap, and the end of the deck plate can be closed again by welding it to a predetermined position. Will be needed. If the plate material is filled with concrete, there is a concern that the plate material will remain corroded even after the work is completed, and the plate material may corrode.

[0004]

[Problems to be solved by the device]

 The problem to be solved by the present invention is that there is no concrete flow stop member that can be quickly and easily attached to the deck plate.

[0005]

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a concrete flow stop member that can be quickly and easily attached to a deck plate. Disclosed is a means including a concrete receiving surface member for directly preventing outflow and a pressing piece member that is adhesively fixed to a beam member to support the receiving surface member.

[0006]

[Action]

 As a concrete flow stop means for deck plates, the concrete receiving plate part standing up against the end part of the deck plate fixed to the beam completely blocks and retains the flow of concrete placed on the deck plate. Means hold the concrete receiving plate portion against the beam or deck plate. The concrete receiving plate portion is in the form of an elongated rectangular plate, and both ends thereof are provided with connecting means capable of connecting with each other, whereby the entire circumference of the deck plate can be surrounded without leakage. The holding means has a horizontal surface fixed to the beam or the deck plate and a reinforcing rib rising from the horizontal surface toward the concrete receiving plate portion, and securely holds the concrete receiving plate portion.

[0007]

【Example】

 FIG. 1 is a front view showing a state in which a concrete flow stop member 10 according to the present invention is attached to a deck plate 12, and FIG. 2 is a right side view thereof. In the present invention, the concrete flow stop member 10 is composed of a concrete flow stop means 16 and a pressing piece 30 used as necessary. As shown in FIG. 1, a deck plate 12 as shown in FIG. 9 is fixed to the upper surface of a beam member 14 usually made of H-shaped steel by the same means as in FIG. On the end surface of the deck plate 12, concrete flow stop means 16 having an L-shaped cross section is arranged. The flow stopping means 16 includes a concrete receiving plate portion 18 which rises to the upper part of the floor concrete in a substantially vertical direction, and a fixed surface portion 20 which extends from the lower edge of the receiving plate portion 18 in a substantially horizontal direction. , A rib portion 22 for reinforcing both portions. The upper end of the rib portion 22 can extend up to the top of the floor concrete. However, it usually ends below the top of the floor concrete. Preferably, this flow stop means 16 is integrally molded with resin or other member. The L-shaped concrete receiving plate portion 18 and the fixed surface portion 20 are formed to be long in the lateral direction. On the other hand, the rib portions 22 are reinforced and arranged between the two surfaces at regular intervals. The thickness of each part of the means 16 and the distance between the ribs 22 vary depending on the pressure and thickness of the concrete 24 poured onto the deck plate 12, the strength of the resin and other materials used, and the like.

Since the flow stop means 16 is used over the entire circumference of the deck plate 12, the adjacent concrete receiving plate portions 18 of the flow stop means 16 are arranged to face each other so that concrete does not flow out from the butted portion. Need to Therefore, if necessary, both end portions of the concrete receiving plate portion 18 can be formed into a form as shown in, for example, FIG. 8, which will be described later, or another form. It is desirable that such an end structure is similarly applied to both ends of the connecting plate for connecting the gap generated between the concrete receiving plate portions of the adjacent concrete flow stopping members 10 and 10.

Adhesive means 26 made of a double-sided adhesive agent or other adhesive agent for fixing the stopping means 16 to the upper surface of the beam member 14 is provided on the lower surface of the fixed surface portion 20. On the other hand, the portion of the concrete receiving plate portion 18 opposed to the deck plate 12 is preferably provided with a leak preventing means 28 made of, for example, a sponge. This prevents concrete from flowing out from the gap formed between the concrete receiving plate portion 18 and the end of the deck plate 12.

Further, when the amount of concrete 24 flowing on the deck plate 12 is large, a pressing piece 30 is provided inside the concrete flow stop means 16 as needed. As shown in FIG. 3, the pressing piece 30 includes a vertical surface 32 that can extend up to the top of the floor concrete, and a horizontal surface that is connected from a lower edge of the vertical surface 32 through an inclined surface 34. 36, and reinforcing ribs 38 reinforcingly connecting both surfaces. The pressing piece 30 is preferably integrally formed of resin or other material, like the stopping means 16. Adhesives 40 and 42 similar to the adhesive means 26 of the concrete flow stop means 16 are applied to the outer surfaces of the vertical surface 32 and the horizontal surface 36 of the top 30. The vertical surface 32 of the pressing piece 30 is joined to the concrete receiving plate portion 18 of the concrete flow stopping means 16 via the adhesive 40. On the other hand, the horizontal surface 36 of the pressing piece 30 is joined to the upper surface 44 of the deck plate 12 via an adhesive 42.

When the concrete flow stop member 10 of the present invention is used, there is no problem in the outer wall work and other steps between the outer edge portion of the deck plate 12 fixed to the beam member 14 and the outer wall (not shown). The concrete flow stop means 16 is brought into close contact with the outer edge portion of the deck plate 12 at a location, and the concrete flow stop means 16 is adhesively fixed to the upper surface position of the beam member 14 wiped with foreign matter by the adhesive means 26. At this time, the leak prevention means 28 is considered to be in close contact with the outer edge portion of the deck plate 12. Then, if necessary, the vertical surface 32 of the pressing piece 30 and the horizontal surface 36 are similarly wiped of foreign matter via the adhesive means 40 and 42. The concrete receiving plate portion 18 of the concrete flow stopping means 16 and the upper surface of the deck plate 12 It adheres to 44 respectively. Generally, it is preferable that the inner pressing piece 30 is arranged so as to be located at an intermediate position between the rib portions 22 of the concrete flow stopping means 16. The concrete flow prevention work in the present invention is completed by the above. Then, concrete 24 is poured onto the deck plate 12 by a usual method. The concrete 12 that has flown to the outer edge of the deck plate 12 is prevented from flowing by the concrete receiving plate portion 18 of the concrete flow stop means 16 and is laminated on the deck plate 12. At the joint between the deck plate 12 and the concrete flow stop means 16, there is a leak stop means 28, so that the concrete 24 is prevented from flowing out from that portion. The concrete receiving plate portion 18 of the concrete flow stopping means 16 that blocks the flow of the concrete 24 flowing on the deck plate 12 is provided with the rib portion 22 of the concrete receiving surface 16 and a holding member used as necessary. Since the reinforcing ribs 38 of the top 30 contact the outer surface and the inner surface of the plate portion 18 respectively and hold the surfaces from both sides, the concrete receiving plate portion 18 is deformed by the concrete 24 flowing on the deck plate 12. There is nothing to do. As a result, the entire pressing piece 30 is embedded in the concrete 24. On the other hand, the concrete flow stop means 16 is completely embedded therein by a concrete which is later introduced into the space defined between the outer wall 6 and the deck plate 12 as shown in FIG. Wait for the concrete to solidify in this state.

FIG. 4, FIG. 5 and FIG. 6 show another embodiment of the present invention. The difference between this embodiment and the previous embodiment is that the concrete receiving plate portion that receives the concrete flow and prevents the flow is configured as a member independent of the pressing portion that supports the concrete receiving plate portion. It is that you are.

In this embodiment, as shown in FIG. 4, the concrete flow stop member 50 contacts the outer edge surface of the deck plate 52 fixed to the H-shaped beam member 14 as shown in FIG. A concrete receiving plate portion 56 for receiving the flow of the concrete 54 flown on the plate 52, an outer pressing piece 58 for supporting the concrete receiving plate portion 56 from the outside, and an optional holding piece 58 shown in FIG. The inner pressing piece 60 is the same as that used in the embodiment. The concrete receiving plate portion 56 is a plate-like member having a slender rectangular shape having a constant height and preferably made of resin or other material, and both ends thereof have a key 62 at one end 62 as shown in FIG. 8A, for example. It has a bent end and the other end 62 has an end which can have a receiving groove for receiving it. This prevents concrete from flowing out from the abutting portion of the plate member 56. However, both end portions can have various shapes other than this. For example, in FIG. 8B, one end has a U shape and the other end embraces it. Further, FIG. 8C shows an example in which both ends are U-shaped and another locking member is fitted into this U-shaped portion. Further, FIG. 8D shows a state in which the corner portions are connected.

It should be noted that a leak stop similar to the leak stop means 28 of FIG. 1 is provided in the lower half of the inside of the concrete receiving plate portion 56 opposed to the corrugated surface of the deck plate as shown in FIGS. 4 and 5. Means 57 are provided.

The outer pressing piece 58 has substantially the same shape as the pressing piece 30 shown in FIGS. 1 and 3. That is, as shown in FIG. 6, a vertical surface 66 that can extend up to the top of the floor concrete, a horizontal surface 70 that is connected from the lower edge of the vertical surface 66 through an inclined surface 68, And a reinforcing rib 72 for reinforcingly connecting 66 and 70. The outer pressing piece 58 is preferably integrally formed of resin or other material. The vertical surface 66 of the top 58 and the outer surface of the horizontal surface 70 are provided with adhesives 74 and 76 similar to the adhesive means 26 of the concrete flow stop means 16 shown in FIG.

When the concrete flow stop member 50 of the present invention is used, the concrete receiving plate portion 56 is arranged in a continuous manner around the entire deck plate 52 fixed to the beam member 14 by welding or the like. To do. When a break occurs in the plate portion 56, concrete flows out from it, so in that case, a short plate portion provided with locking means as shown in FIG. 8 at both ends should be used to eliminate the break. . Next, while the leak preventing means 57 of the concrete flow stop plate portion 56 is pressed so as to contact the outer edge of the deck plate 52, the outer pressing pieces 58 are fixed to the beam 14 at predetermined intervals via the adhesive means 76. At the same time, it is also fixed to the plate portion 56 via the adhesive means 74. As a result, the concrete receiving plate portion 56 can be fixed on the beam member 14 while being in close contact with the deck plate 52.

In the present invention, when the load of the concrete 54 on the deck plate 52 is not so large, the outer pressing piece 58 alone can sufficiently provide the concrete flow stopping action, but the load of the concrete is increased. In this case, it is desirable to use the inner pressing piece 60 having substantially the same structure as the pressing piece 30 of the embodiment shown in FIG. 1 at the same time. The holding piece 60 is used in the same manner as the holding piece 30 shown in FIGS.

FIG. 7 shows an arrangement state of the concrete receiving plate portion of the edge portion parallel to the corrugated shape of the deck plate 52. In this case, a part of the horizontal surface of the inner pressing piece 60 on the inclined surface side may be disengaged from the deck plate 52. In that case, the horizontal surface portion may be configured to be slightly longer. Further, in this case, it is not necessary to provide the leak preventing means 57 as shown in FIG. 4 in the inner lower half of the concrete receiving plate portion 56. This is because there is no concern that concrete will flow out. Of course, even if such a means is provided, it can be similarly used.

Although the concrete flow stop members 10 and 50 of the present invention are described as requiring a top for supporting the concrete receiving plate portions 18 and 56 from both sides thereof in the drawings, of course, the pressing tops are required. It is also possible to arrange the tops so as to support only the outer side or only the inner side or alternately support the outer side and the inner side. Further, in the embodiment of FIG. 1, the concrete flow stop means 16 and the pressing piece 30 are formed as separate parts, but they may be formed as an integral part. Further, only the rib 22 of the concrete flow stop means 16 may be integrally formed with the pressing piece 30. In this case, a cutout may be provided at the upper edge of the concrete receiving surface 18 of the concrete flow stop means 16 and the integral member can be engaged there. Further, in the embodiment shown in FIG. 4, the concrete receiving plate portion 56 and the inner pressing piece 60 can be integrally molded.

In the present invention, the mounting positions of the pressing pieces and the intervals between them should be such that the concrete receiving plate portion can withstand the concrete flow pressure during concrete pouring and does not interfere with the outer wall construction or other processes. Of course, it is necessary to take into consideration.

[0021]

EFFECTS OF THE INVENTION Since the present invention has the above-mentioned configuration, the mounting work is easy and the construction period can be reduced. Further, no skill is required for the mounting work. Since there is no problem of rust or corrosion, it can be maintained as it is for a long time. Furthermore, since the flow stop member of the present invention is lightweight, it is very easy to carry in, unload, arrange, etc. even at a site quite high from the ground. Further, the unit price of the member is low, which is economical.
