Abstract

PURPOSE:To obtain a strong coupler for steel plate cells by a method in which a pair of L-shaped coupler metals are welded to the periphery of a steel cell and the coupler metal of arc steel plate is thrust through the coupler metals welded with a reinforcing steel strip between the outside of the tip of each L-shaped coupler metal and the peripheral side of the steel cell. CONSTITUTION:A pair of L-shaped coupler metals 12 are projectionally provided to the periphery of a steel cell 1 in such a way as to extend its straight piece 12b along the diametral direction of the steel cell 1, and a rubber seal 13 is laminated on the inner surface of a hook-like bent piece 12a. Then, a reinforcing steel strip 14 is welded between the outside of the tip of each L-shaped coupler metal 12 and the steel cell 1, and an insert metal 17 is provided on both edges of an arc steel plate 16. The huge steel cell 1 is penetrated into the seabed by a vibro-pile driver, etc., soil and sand are charged into the cell, and while piercing the coupler metal at side end of the arc steel plate 16 into the coupler metal 12 on the periphery of the steel cell 1, the cell 1 is penetrated into the seabed and soil and sand are packed into it. Thus, a dam is constructed.

Description

[Detailed description of the invention] In the construction of the cell embankment body for both construction works, a huge cell steel shell (11) made of welded steel plates may be compressed using a vibrating pile driver, etc., and then placed inside the cell. Filling earth and sand (2) is put in to make it stand on its own. 1) Joints M provided at the four ends of the arc steel plate (:3) Push the arc steel plate to the pottery bottom (3
) is suspended, and the vibrating pile driver is used to press the pile into the ground, causing a 12-diffusion accumulation of earth and sand, and repeating steps 1 and 8 below to complete the cell steel shell (1). This is a structure in which m embankment bodies are integrally connected to the plate i31. (Fig. 1 and 218!! J-H) Therefore, as shown in Fig. 6 to Fig. 5, the joints of the steel plate cells of the autopsy are connected to the cell steel shell t l l l /,) in one pair in the outer circumferential direction. L-shaped μ-hand hardware (4) (41, or J-shaped - hand hardware t
51 (5) is protruded from the parking plate J4 (AJ'r customary), and the T-shaped metal fitting (Bl) formed in the arched steel plate (3 mm) is cylindrical - → metal fitting (B2 ) to the said chotekin J4 (
It is composed of 9 spaces for the handle of the ball and a kanshin.

Therefore, the arc copper plate (
When filler soil and sand are poured into 31, internal earth pressure generates a force F in the direction of separating the joint fittings (A) (Bl), and in response, the joint fittings of the cell steel shell (1) (A) is easy to place & cedar in Figures 6 and 7,
III It forms a strong joint but has the disadvantage of separation.

In order to eliminate such defects, as shown in Fig. 8, reinforcing lips (6) are arranged at predetermined intervals around the outer periphery of the joint hardware (4) of the cell steel shell (1). Although it has been proposed, since concentrated stress acts locally on the cell steel shell (IIK), reinforcing measures such as a reinforcing plate (7) on the cell steel shell (1) side are required. ) The presence of the cell steel shell (11) increases the large resistance in the soil, making construction difficult.

The present invention has been proposed in order to eliminate such missed lectures, and involves protruding a pair of fittings extending in the diametrical direction from the outer periphery of the cell steel shell. A hook-shaped portion having greater strength and rigidity than the portion of the fitting connected to the cell outer shell is provided at the tip of the fitting, and the hook also extends between the outer surface of the fitting and the outer circumferential direction of the cell steel shell, Formed between the joint of the cell me, which is formed by a solid layer of reinforcing bands m extending continuously in the generatrix direction 6c of the same cell w4, and the joint fittings of the cell 11"jL and the joint fittings of the cell 11" on both ends of the arc steel plate. The present invention relates to a steel plate cell joint characterized in that it consists of an arc steel plate joint formed by disposing a MAM metal alloy lying in a space for the joint.

In accordance with 1 and 1 of the present invention, as described above, a pair of joint metal fittings are protruded from the outer periphery of the cell wA cup and extend along the same straight φ force, and the same metal fitting is provided at the tip of at least one of the joint metal fittings. The arc steel plate fitted between the joint of the cell steel shell and the pair of joint fittings in the same joint is TA meeting +1
When a force is applied between the ◆ and the ◆ insert metal fittings on the edge, this force is strongly resisted by the tongue portion, and the outer surface of each of the joint metal members and the outer circumferential surface of the metal It was solidified over a period of time. The same cell: The reinforcing band that extends continuously in the direction of the generatrix of J4 prevents the joint members from deforming due to the acting force of each column, creating a strong joint. Since the copper sleeves are arranged continuously in one direction of the cell steel shell, the reaction force against the cell steel shell is wide (distributed, and the deformation of cell 9II/I4 mosquitoes is 1 mm). Since it is equalized, there is no need to reinforce the cell steel, or the dimensions of the reinforcing tooth plate for the cell* can be made smaller, and the penetration resistance when purchasing m-cooked cells in the soil can be minimized. The present invention has many advantages, such as being able to suppress

The present invention will be described below with reference to the illustrated embodiments.
