Description

DETAILED DESCRIPTION OF THE INVENTION [0001] [Industrial application field] The present invention relates to a curb joint used for setting a joint at a joint in the construction of a concrete or stone curb installed on a side end of a road or the like. This is a formwork that can be widely used for joint construction in curb installation such as road construction. [0002] [Conventional technology] Conventionally, curb construction in road construction and the like,
In order to pour and inject the joint material, a plate material is brought into contact with the side of the seam of the curb, a rope material is pushed into the seam, or a paper or cloth adhesive tape is attached to the side of the seam, and the joint is joined from the top. The material was injected, and after the injection, the backing plate, the rope material, the adhesive tape, and the like were removed, and finishing was performed using a joint iron. [0003] [Problems to be Solved by the Invention] In the conventional curb construction, as described above, a patch plate or a rope is used at the joint to inject the joint material, or a cloth or paper adhesive tape is attached. . Therefore, when using a backing plate or a rope, it takes time and effort, and the work efficiency is remarkably reduced.When using an adhesive tape, the adhesive tape becomes disposable, which not only increases the cost, but also causes incomplete adhesion of the adhesive tape. For this reason, there is a problem that the adhesive tape is peeled off at the time of injection of the joint material, so that the joint material cannot be injected. Also, if the curb is sandy or dusty, wet or wet, the adhesive tape will be incompletely bonded, so it is necessary to remove sand and dust before construction. It had to wait for it to dry, which was one of the reasons for the delay in the construction period. [0004] [Means for Solving the Problems] The present invention is capable of performing curb joint construction without using any backing plate, rope material or adhesive tape in order to solve the conventional problems. is there. That is, two mold members having an L-shaped cross section for bringing the opposing surface into contact with the joint side surface of the curb, two upper and lower support members connected to appropriate positions of the mold village, and a lower side contacting the upper surface of the curb It is constituted by a casting frame suspended on a supporting material, and the two holes and the two holes are provided in the molding and the supporting material, respectively, so that the connecting position can be appropriately moved and fixed. It is a formwork for joint construction of a curb, which is provided with a bolt that can penetrate and move as needed and a nut for tightening the bolt. [0005] [Operation] The operation of the present invention will be described with reference to FIGS.
First, the two L-shaped cross-sections 1 and 2 are applied to the side surface of the curb 10, and the connection positions of the two cross-sections 1 and 2 and the two supports 3 and 4 are appropriately moved to form the cross-sections 1 and 2. Support materials 3 and 4 are curb 1
According to the shape and dimensions of the curb 10, the opposing surfaces of the L-shaped cross sections 1 and 2 are brought into contact with the seam 11 of the curb 10, and the lower support 4 is brought into contact with the upper surface of the curb 10. , Bolt 8
And the nut 9 are tightened to fix the connection. Next, a joint material such as cement is poured from above the opening of the pouring frame 5 suspended in the lower supporting member 4, and after the pouring, the upper supporting member 3 is grasped and lifted to be removed from the curb 10. Thereafter, the outer surface of the joint is finished with a predetermined joint iron. [0006] In the subsequent seam construction of the next curbstone 10, since the curbstones 10 have the same shape and the same size, the lower ends of the profiles 1 and 2 are connected to the side surfaces of the next curbstone 10 in the connected state. If it is inserted and abutted, the lower support member 4 abuts on the upper surface of the curb 10, so that the joint material can be injected from the pouring frame 5 suspended as described above. [Embodiment] An embodiment will be described with reference to FIGS. 1, 2, 3 and 4. Two L-shaped cross-sections 1 and 2 for abutting surfaces facing the side surfaces of the curb joints, and the cross-sections 1 and 2
Upper and lower two support members 3 connected to the approximate girder space at appropriate positions
And 4 and a pouring frame 5 suspended from a lower supporting member 4 which is brought into contact with the upper surface of the curb. A long hole 6 for moving the penetrating bolt 8 is provided on a surface of the moldings 1 and 2 that does not contact the curb, and a short hole 7 for moving the penetrating bolt 8 is provided in the supports 3 and 4. Provide. The lengths of the long hole 6 and the short hole 7 are appropriately set according to the shape and size of the curb to be processed.
After determining the connection positions of the mold members 1 and 2 and the support members 3 and 4, a nut 9 to be tightened and fixed is screwed. Lower support 4
As shown in FIG. 4, the pouring frame 5 is provided with a hooking portion 5 'on the support member 4 side, and has one side surface inclined so that the joint material can easily flow in. [0008] Accordingly, the two mold members 1 and 2 and the two support members 3 and 4 move the bolts 8 passing through the long holes 6 and the short holes 7 provided respectively, and tighten the nuts 9 at appropriate positions. Thereby, it can be used according to the shape and size of various curbs. [0009] FIGS. 5 and 6 show the case where the present invention is used for seam construction of a curbstone, wherein the shapes 1 and 2 and the supports 3 and 4 are fixed at a connection position by bolts 8 and nuts 9 and have an L-shaped cross section. The opposing surfaces of the mold members 1 and 2 abut against the side surface of the seam 11 of the curb 10, and the lower edge of the lower support member 4 and the lower edge of the inclined side surface of the casting frame 5 sandwich a gap between the seams as shown in FIG. Abuts on the upper surface of the curb 10. Therefore, the joint material poured from the casting frame 5 can be injected into the joint 11 without fouling the curb 10 and without waste. Further, since the mold members 1 and 2 abutting on the side surface of the joint 11 are fixed by the lower support member 4 and the upper support member 3, they do not spread when the joint material is injected, and the water content of the joint material does not increase. Is discharged appropriately, so that the joint construction efficiency is improved. [0010] [Effects of the Invention] In the present invention, the connection surface is initially adjusted to the shape and size of the target curb, and thereafter, the opposing surface of the mold material that is simply inserted into the joint side surface of the curb is brought into contact with the curb. With only this operation, the injection of the joint material is facilitated, the efficiency of the curb work is remarkably improved, and the adhesion of the joint material to the curb is prevented, so that the finish is improved.
In addition, by appropriately moving the connection position of the shape member and the support material by operating the port and the nut, it can be adapted to any shape and size of the curb, so that it can be repeatedly used for construction of various curbs, and is economical. It is also effective.
