Connecting apparatus for laminating foamed resin blocks and connecting lamination method using said apparatus

Abstract

Provided is a connecting tool capable of efficiently integrally connecting laminated foamed blocks, in a civil engineering construction method using a laminated product of foamed resin block as civil engineering material, and being prevented from loosening or dropping out from the foamed resin blocks after the connecting integration. This connecting tool for lamination of foamed resin blocks comprises a horizontal head part 12 and insert parts 13a and 13b extended vertically from both ends of the head part 12.

Description

technical field [0001] The present invention relates to a civil engineering method (hereinafter referred to as soil engineering method) in which a material of parallel connected and laminated foam resin blocks (hereinafter referred to as foam block) is used as a civil engineering material. A connecting device for connecting foam blocks to each other and a method for connecting and laminating foam blocks using the connecting device. Background technique [0002] In recent years, in civil engineering such as roads and land construction, the above-mentioned earth-filling method has been gradually utilized, and materials in which large foam blocks are laminated are used as earth-filling materials or embedding materials. [0003] The foam block is formed of foamed polystyrene, polyurethane, etc., and is often used as a standard block processed into a square shape of length 2 m×width 1 m×thickness 10 to 50 cm. [0004] For example, in Figure 8 In the shown road soil engineering ...

Problems solved by technology

[0010] But, the previous method that utilizes connecting plate 5,6 to connect foam block 4 has: 1. every two layers must be connected to opposite foam block 4, can not connect more than 3 layers at once, so efficiency is extremely low; 2. claw 7 and object The angle of the claw is easy to change when it is in contact, so there are many situations that need to be corrected before use, which will inevitably cause a decrease in operating efficiency; ③ because the height of the claw 7 is about 25mm, it is easy to come off due to vibration, etc. After the connection, it is easy to disengage when vibration is applied up, down or left and right due to earthquakes, etc., and the connection force is weak; ④ During the operation, the claw 7 stabs the worker's feet, which is more dangerous; ⑤ Due to rust, etc., the connecting plates 5 and 6 Short life span; etc.

[0011] On the other hand, the method of inserting rod-shaped connectors to connect the foam blocks of the upper and lower layers can roughly solve the problem of the above-mentioned connecting boards, but: ① because it needs to be inserted one by one, the work efficiency is poor; When vibration is applied up and down or left and right, there is a possibility of loosening or falling off; ③ although the shaft is provided with a protrusion for preventing falling off, the above problem can be solved (refer to Patent Document 2 Figure 10 , Figure 11 ), but when one end needs to be pulled out due to some reasons, it is very difficult to pull out; ④Since the shaft part is formed by one piece, the adjacent foam blocks cannot be integrally connected in the horizontal direction, even if it is used in the head A connector having both ends formed as hooks (refer to Patent Document 2 Image 6 , Figure 8 , Figure 11 ), and the surface layer of the foam block can only be integrally connected by using the short hook portion, so the strength of its integral connection is very weak and not sufficient
