I will not. Therefore, after adjusting the position of the door contact 33 such as the vertical degree, the base G is interposed and the structure is fixed to the wall body F.
[0005]
[Problems to be solved by the invention]
When replacing existing water control doors with new ones, water is always flowing through the waterways so that the functions of the treatment system located downstream will not be stopped ( It is desirable to carry out construction as unrestricted water). And as a method of installing a water control door in the state of this constant water,
(1) Attach only the door stop to the wall body first, and insert the door body into the door stop later.
(2) Insert the door into the door and attach the door to the wall while keeping the door open.
Such a method is conceivable.
[0006]
However, as in the methods (1) and (2) above, when the installation work is performed with the door removed from the door or the door opened, For example, when the door body 34 is lowered and closed again due to a subtle positional shift or the like, the water stoppage between the door stop water stop plate 36 and the door body water stop plate 37 is deteriorated. There is. Further, there are some operations that can be performed only when the door body 34 is not fully closed, such as confirmation of a gap and adjustment of the stopper 45 described above, during the mounting operation. For this reason, conventionally, the water control door is always installed in the factory-shipped state (the door body is incorporated in a fully closed state per door). The work form of blocking the flow of water and installing the water control door was adopted. Therefore, during this time, there is a problem that water does not flow downstream, and the function of the downstream processing system stops.
[0007]
This invention was created in order to solve such a problem, and it aims at providing the continuous water installation construction method of the water control door which can be installed in a continuous water state.
[0008]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides a water control door provided with a door stop attached to a wall body via a foundation and a door body fitted into the door so as to be movable up and down. 1) Adjust the positioning of the water control door so that the door is fully closed and a gap is formed between the wall and the door to allow water to pass through, and the water is controlled by the bolts and nuts attached to the wall. The step of fixing the door and (2) the step of opening the door body and placing the underwater mortar as a foundation between the wall body and the door stop were performed in that order.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described with reference to FIGS. In the present invention, the basic structure of the water control door A is substantially the same as, for example, the water control door described in the prior art, and a pair of vertical frame portions 1 and 1 having vertical grooves 2 and 2 are formed. The door unit 3 is configured so that the doors 2 and 2 are opposed to each other, and the door body 4 is fitted into the door unit 3 so as to be movable up and down with the longitudinal grooves 2 and 2 as a guide. The door body 4 is moved up and down by an opening / closing machine (not shown) positioned above. The door stop 3 and the door body 4 are made of cast iron (FC200) or the like. In the lower part of the water control door A, a rectangular opening surrounded by the left and right vertical frame portions 1 and 1 and the upper and lower horizontal frame portions is formed, and when the door body 4 is lowered, the opening portion is formed. Is supposed to close.
[0010]
Door stop water blocking plates 6 are fixed to the front surfaces of the left and right vertical frame portions 1 and the upper and lower horizontal frame portions, and on the rear surfaces of the upper, lower, left and right side edges of the door body 4 corresponding to the door stop water blocking plates 6. The door body water stop plate 7 is fixed. On the side of the door 3, a wedge-shaped fixing tool 8 having an inclined surface is attached to the lower front surface via the presser plate 5, and on the door body 4 side, the wedge shape on the front surface of both side edges is attached. A wedge-shaped member 9 is attached at a position corresponding to the fixing tool 8. When the door body 4 is lowered, the wedge-shaped member 9 and the wedge-shaped fixing tool 8 come into sliding contact with each other to push the door body 4 rearward. When the door body 4 is completely closed, the door body 4 is pressed against the door stop 3, and the door stop water stop plate 6 and the door body water stop plate 7 are brought into close contact with each other to keep the water stop.
[0011]
In the present invention, when installing the water control door A in a water channel in a state of flowing water, (1) the door body 4 is fully closed, and a gap through which water passes between the wall body F and the door stop 3 is provided. Adjusting the positioning of the water control door A as formed, fixing the water control door A with bolts and nuts attached to the wall body F, and (2) opening the door body 4 to open the wall body F. The step of placing underwater mortar as a base G between the door and the door stop 3 is performed in that order.
[0012]
The case where the water control door A is installed in the wall body F in the state which poured water into the waterway, for example is demonstrated. The mode shown in FIG. 1 shows a case where a plurality of special nuts 10 are fixed to the wall body F in advance by underwater work or the like. An auxiliary bar 12 is fixed to the reinforcing bar 11 of the wall body F, and the special nut 10 has a shaft part 10b so that its nut part 10a protrudes from the wall body F toward the mounting side of the water control door A. It is fixed to the auxiliary muscle 12. A gate fixing bolt 13 (corresponding to the bolt described in the claims) is screwed onto the nut portion 10a. A nut 14 is screwed to each gate fixing bolt 13. The nut 14 is a member that plays a role in positioning adjustment of the water control door A. In this embodiment, the water control door A is fixed to the embedded fixing plate 15 with a bolt (not shown) or the like, and the nut 14 for each gate fixing bolt 13 is pressed against the nut 14 while the rear surface of the embedded fixing plate 15 is pressed against the nut 14. By appropriately adjusting the screwing position, the positioning of the water control door A is adjusted accurately. Of course, it is possible to adopt a structure (for example, the structure shown in FIG. 8) that directly attaches the rear surface of the door stop 3 to the nut 14 without providing the embedded fixing plate 15.
[0013]
During the positioning adjustment of the water control door A, the door body 4 is in a fully closed state, and the operator performs not only a positioning adjustment but also a check of a skim and a height adjustment of a stopper (such as the stopper 45 shown in FIG. 5). When the positioning adjustment or the like of the water control door A is completed, the embedded fixing plate 15, that is, the water control door A is fixed by fastening a nut 16 (corresponding to a nut described in claims) to each gate fixing bolt 13. During the above steps, water flows downstream through a gap formed between the front surface of the wall body F and the rear surface of the embedded fixed body 15 (door stop 3) as indicated by an arrow. Accordingly, the door body 4 is kept in the fully closed state at the time of shipment from the factory, that is, the water stop performance by the door stop water stop plate 6 and the door body water stop plate 7 is maintained as the factory shipment state. The uncontrolled water installation of the water control door will be realized.
[0014]
When the above steps are completed, the door body 4 is opened, a formwork is temporarily provided, and underwater mortar is placed as a foundation G in the gap portion as shown in FIG. Thereafter, water flows downstream from the water control door A that has been opened.
[0015]
As shown in FIG. 3, the special nut 10 can be an adhesive anchor (chemical anchor) in which a wall body F is drilled and an adhesive is filled in the hole Fa and fixed. . Further, by making the through hole 15a for the gate fixing bolt 13 a large-diameter hole or a long hole in the embedded fixing plate 15, the position adjustment of the water control door A in the left-right direction can be easily performed. Reference numeral 17 denotes a washer.
[0016]
Moreover, as a fixed aspect of the water control door A with respect to the wall F, it is good also as a structure which uses together the chemical anchor 18 and the special nut 10 welded to the auxiliary | assistant reinforcement 12, as shown in FIG.
[0017]
As mentioned above, although preferred embodiment was described about this invention, this invention is not limited to these embodiment, In the range which does not deviate from the meaning, a design change is possible suitably.
[0018]
