2. Description of the Related Art Conventionally, a mold for a large-scale assembled oblique bridge box carve requires two molds, a lower frame and an upper frame.
In this structure, a convex middle frame (2) provided on the upper surface of a long bottom plate (1) is integrally formed, and a front side plate (3), a rear side plate (4), a right side plate (5), The left side plate (6) is detachably erected. In order to manufacture the lower oblique bridge box carve (8) using this lower frame, the lower frame assembled beforehand is installed at a predetermined position. First, the pre-assembled rebar is installed at a predetermined position inside the lower frame. Next, while the concrete is being put into the lower frame, a vibrator, a compressor, or both of them are used together, or the concrete is compacted by a method having an effect equal to or higher than these. After solidification, the front side plate (3), the rear side plate (4), the right side plate (5), and the left side plate (6) are removed. Then, lower box bridge (8) is supported by crane and bottom plate (1) is lifted.
Keep away from. The lower oblique bridge box carve (8) is stacked at a predetermined position, and the front side plate (3), rear side plate (4), right side plate (5), left side plate (around the bottom plate (1). 6) is erected again and returned to the original state, and the lower frame is returned to the initial state. Thereafter, the lower oblique bridge box carve (8) is molded in the above-described manner until a predetermined quantity is reached.

Mold the grate (8). The molded lower and upper large assembled diagonal bridge box carton (8) is transported to the construction site. After that, the upper side and the lower side were combined, and a large number of the upper side and the lower side were combined and used until they became a predetermined length (see FIG. 6).

However, the formwork for the large-scale assembling bridge box carve must be prepared with a lower frame and an upper frame, and when the concrete is flowed, the lower frame is used. After the molding of the frame was completed, the lower frame had to be put away and the upper frame had to be installed at a predetermined position, and the replacement work of the lower frame and the upper frame was troublesome and took a lot of time. Therefore, it takes a long time to receive an order and deliver it, and it is difficult to perform an emergency work. Moreover, in general, this mold has been completely molded in the ordered quantity, and after being stored for a certain period of time, there is little use of the mold and it is an obstacle, so it is discarded and all the molds are discarded. However, it was a waste of resources, and it was difficult to reduce the cost of the large-scale assembling bridge box carton (8).

Further, in manufacturing the large-sized assembling bridge box carve (8), the total quantity of orders is divided into several times in order to make an economical supply.
In many cases, the oblique bridge box carve (8) for all orders cannot be manufactured due to the manufacture of the product or the customer's request. For this reason, the quantity managed by the formwork tends to increase, and since this formwork is large, a wide storage space is required, and the space cannot be effectively used.

The middle frame (2) of the mold is formed in a long and convex shape integrally and fixed to the upper surface of the bottom plate (1). After the concrete is poured into the mold, Since it condenses before it is solidified, the large-sized assembling bridge box carton (8) is likely to be twisted or distorted. As a result, there is an error in the position of the bolt holes in the diagonal part and it becomes impossible to connect,
In addition, the displacement of the connecting hole between the upper and lower large-scale assembled oblique bridge box carburts (8), the displacement of the connecting hole in the length direction, or the displacement at the time of connecting the anchor bolts. It will be difficult to connect. Therefore, it is difficult to obtain a product conforming to the standard unless the inner frame (2) is corrected. Moreover, it is necessary to correct the inner frame (2) after molding one piece. As a method of straightening the work, heat is applied to the straightening portion, and it is tapped out with a large hammer or a ball,
Alternatively, a force must be applied with a jack or the like, and a skilled technique is required to perform the correction work, and it is difficult to secure a correction worker.

In addition, since the precision of the large-sized assembled oblique bridge box carve (8) molded by the above-mentioned mold is not so good, the conventional idea is to simplify the mold by sharing the upper and lower frames. Since there is no pressure, and pressure is applied to the inside of the mold, it is considered that it is desirable that the inner frame (2) is an integral type with as few adjustment points as possible. There has never been an idea to establish.

The present invention makes it possible to manufacture the upper and lower large assembled diagonal bridge box carats with the same mold by simply exchanging only the variable pieces of the left and right diagonal parts, and the correction work is easy for anyone. The purpose is to provide a formwork for the assembled bridge bridge box carton.

Next, description will be made on a case where the lower large-sized assembling bridge box carve (8) is manufactured by using the present invention. The pre-assembled rebar is installed at a predetermined position inside the lower frame. First, the concrete is molded while putting the concrete into the lower frame and compacting the concrete with a vibrator or a compressor. After solidification, the fastening member (7) is loosened to remove the front side plate (3), the rear side plate (4), the right side plate (5), and the left side plate (6). Then, the lower large assembling bridge box carve (8) is lifted by a crane and separated from the bottom plate (1). The large-scale assembling bridge bridge box carcass (8) is stacked at a predetermined position, and the front side plate (3), the rear side plate (4), the right side plate (5), and the left side plate are provided around the bottom plate (1). (6) is erected again, returned to the original state, and the lower frame is returned to the initial state. At this time, immediately after the lower large assembling bridge bridge box car (8) is removed from the lower frame, it is immediately inspected whether the connecting holes and the main dimensions are within the standard, and the lower frame is assembled. Sometimes the defect is corrected. In this case, the correction work can be performed accurately and in a short time by a simple work of just re-installing the misalignment at each mounting location such as the variable pieces (22) and (23) and the shelf (21). Then, the next molding is started.
In the same manner as above, the lower side box bridge box carburts (8) are molded to a predetermined quantity.

The product of the present invention has a lower side and an upper side only by exchanging only the variable pieces (22), (23), (22 '), (23') attached to the diagonal portions of the left and right ends of the middle frame (2). Since the large-scale assembled oblique bridge box carburt (8) can be manufactured with the same form and only one frame member is required, prepare the lower and upper frames in a short period of about 40% compared to the conventional one. You can Further, in manufacturing the large-scale assembled oblique bridge box carve (8), the replacement work of the lower frame and the upper frame can be greatly omitted, and the correction work time can be shortened. Therefore, it has become possible to shorten the period from receiving an order to delivering it. It is also possible to make time for emergency work.
