Description

Technical Field

[0001] The utility model belongs to the technical field of building structures and relates to a connecting structure between a Larssen steel sheet pile and a purlin. Background Art

[0002] The Larssen steel sheet pile is a civil engineering material widely used in projects such as foundation pit support, retaining walls, and breakwaters. The purlin is an important component for fixing and supporting the Larssen steel sheet pile. In the existing connection method, usually a sealing plate is used to seal the bottom in the gap between the purlin and the Larssen steel sheet pile, and then C20 fine aggregate concrete is poured into the gap for filling to ensure that the purlin can be evenly stressed.

[0003] However, this method has many deficiencies in practical applications. During the construction of a cofferdam in water, a construction ship is usually used for operation. Since there is no road access, the installation of the sealing plate and the pouring of concrete both need to be carried out on the ship. The construction line is long and the difficulty of working on water is high, increasing the complexity and risk of construction. Moreover, after the construction is completed, the poured concrete pads cannot be recycled and reused, resulting in a relatively high construction cost. In addition, this method also has high requirements for the construction period and is not conducive to rapid construction. Content of the Utility Model

[0004] The purpose of the utility model is to provide a connecting structure between a Larssen steel sheet pile and a purlin that simplifies the construction process and reduces the maintenance cost.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A connecting structure between a Larssen steel sheet pile and a purlin, comprising:

[0025] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Please refer to Figure 1 and Figure 2 , the connection structure 100 of the Larssen steel sheet pile and the waling shown in a preferred embodiment of the present application includes a waling 1, a Larssen steel sheet pile 2, a spacer 3 and a tie rod 4.

[0027] The waling 1 is a structural cross beam for providing support and stability. The waling 1 is connected to the Larssen steel sheet pile 2, forming the basic part of the connection structure 100 of the Larssen steel sheet pile and the waling.

[0028] The Larssen sheet pile 2 abuts against the waling 1, and a number of installation spaces 21 are formed between the Larssen sheet pile 2 and the waling 1. The Larssen sheet pile 2 is a steel structure member for retaining soil and providing support, with high strength and durability.

[0029] The spacer 3 is arranged in the installation space 21. The spacer 3 includes a base 31, a movable seat 32, and a locking member 33 that are coaxially arranged. The base 31 abuts against the Larssen sheet pile 2. One end of the movable seat 32 is connected to the base 31 and can slide relative to the base 31 along the axial direction of the base 31. The other end of the movable seat 32 abuts against the waling 1. The locking member 33 is arranged on the movable seat 32 and can restrict the axial movement of the movable seat 32. The base 31 and the movable seat 32 respectively abut against the Larssen sheet pile 2 and the waling 1, and the movable seat 32 can slide along the axial direction of the base 31, enabling the spacer 3 to adapt to different installation requirements and meet the installation of installation spaces 21 of different sizes. Through the restriction of the locking member 33, the movable seat 32 can be fixed in place, thus ensuring the stability of the spacer 3.

[0030] The tie rod 4 runs through the waling 1, the Larssen sheet pile 2, the base 31, the movable seat 32, and the locking member 33 along the axial direction of the base 31. One end of the tie rod 4 away from the Larssen sheet pile 2 is fixed to the waling 1. One end of the tie rod 4 is fixed to the waling 1, and the other end provides a through connection through the spacer 3 and the Larssen sheet pile 2, enabling each component to be firmly connected together to form an integral structure.

[0031] In this application, by arranging the spacer 3 and the tie rod 4 in the installation space 21, a tight connection between the Larssen sheet pile 2 and the waling 1 is achieved. Relying on the sliding connection between the base 31 and the movable seat 32, the Larssen sheet pile 2 can be tightly abutted, thus adapting to different environments, simplifying the construction process of the sealing plate and concrete pouring, reducing the construction difficulty and danger. At the same time, the spacer 3 and the tie rod 4 can be reused, reducing the maintenance cost, and significantly improving the construction efficiency and economic benefits.

[0032] In this embodiment, the movable seat 32 includes a first end 321 that abuts against the waling 1 and a first protrusion 322 arranged on the first end 321. The base 31 includes a second end 311 that abuts against the Larssen sheet pile 2 and a second protrusion 312 arranged on the second end 311. Along the axial direction of the second protrusion 312, a receiving hole 3121 is formed on the second protrusion 312. The first protrusion 322 can be inserted into the receiving hole 3121 and can move relative to the axial direction of the receiving hole 3121 to ensure that the first end 321 and the second end 311 mutually abut against the waling 1 and the Larssen sheet pile 2, thus adapting to different environments. The locking member 33 is arranged on the first protrusion 322 to restrict the movement of the first protrusion 322 in the receiving hole 3121, thus ensuring the stable connection between the movable seat 32 and the base 31.

[0033] The first protrusion 322 is threadedly connected to the receiving hole 3121, and the locking member 33 is a locking nut. The threaded connection not only makes the installation and disassembly more convenient, but also provides a strong fixing force to ensure the firm connection between various components. The use of the locking nut further enhances the reliability of the connection. By tightening the locking nut, the loosening of the first protrusion 322 in the receiving hole 3121 can be effectively prevented.

[0034] A plurality of first reinforcing angle irons 323 are arranged on the first end portion 321 along the circumferential direction of the first protrusion 322. The first reinforcing angle irons 323 are connected to the first protrusion 322. By this circumferential arrangement, the force distribution is made more uniform, further improving the structural stability and strength. A plurality of second reinforcing angle irons 313 are arranged on the second end portion 311 along the circumferential direction of the second protrusion 312. The second reinforcing angle irons 313 are connected to the second protrusion 312. The function of the second reinforcing angle iron 312 is similar to that of the first reinforcing angle iron 323, mainly to enhance the structural strength of the base 31.

[0035] Please refer to Figure 3 , the first reinforcing angle irons 323 and the second reinforcing angle irons 313 are respectively arranged uniformly along the circumferential directions of the first protrusion 322 and the second protrusion 312 to ensure uniform force on the connection part, thereby avoiding structural deformation or damage caused by excessive local force. Preferably, both the first reinforcing angle irons 323 and the second reinforcing angle irons 313 are provided with four and are arranged in a cross shape.

[0036] Optionally, a gasket 34 is provided between the locking member 33 and the base 31. The gasket 34 can effectively reduce the friction between the locking member 33 and the base 31, prevent direct contact between metal parts, and reduce wear and damage. Moreover, the gasket 34 can also play a certain buffering role, absorbing part of the vibration and impact force, thereby further improving the durability and stability of the connection structure 100 between the Larssen steel sheet pile and the waling.

[0037] An adjusting nut 41 that forms a threaded connection with the tie rod 4 is provided on the tie rod 4. The adjusting nut 41 abuts against one end of the waling 1 away from the Larssen steel sheet pile 2. The adjusting nut 41 can move along the axial direction of the tie rod 4. By the abutment of the adjusting nut 41 and the moving seat 32, the fixing of the tie rod 4 is realized.

[0038] The base 31, the moving seat 32 and the locking member 33 are made of steel. The steel not only ensures the mechanical strength and durability of each component, but also improves the overall performance and reliability of the connection structure 100 between the Larssen steel sheet pile and the waling. The use of steel enables these components to maintain good functional states in harsh construction and use environments to meet the requirements of practical applications.

[0039] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0040] The above-described embodiments only express several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
