Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for glass fiber reinforced plastic (GFRP) continuous walls, specifically a frame-type GFRP continuous wall joint assembly. Background Technology

[0002] With the rapid development of deep foundation pit and underground rail engineering, diaphragm walls are widely used as retaining structures. The so-called diaphragm wall is not actually continuous; it is composed of multiple unit sections connected to each other in some way. The diaphragm wall is constructed by using a trenching machine on the ground to excavate a narrow, deep trench along the perimeter axis of the deep excavation project, under the condition of mud wall protection. A steel cage is placed in the trench, and underwater concrete is poured in using the tremie method to form a unit section. A diaphragm wall joint is placed at the edge of the previous unit wall, and then the next unit wall section is constructed.

[0003] The joints of existing diaphragm walls remain the weakest points and the most prone to water leakage. Workers often add water-stop iron sheets during joint construction to enhance the anti-seepage ability of the diaphragm wall joints. However, the iron sheets are made of iron and are prone to aging, which reduces their anti-seepage ability. In addition, the traditional steel cage frame of the diaphragm wall will also age, making the joints of the diaphragm wall prone to water leakage and thus reducing their anti-seepage ability.

[0026] An I-beam steel frame 3 is installed between the two continuous wall frames. The two sides of the I-beam steel frame 3 are welded with butt joint blocks 4. The end of the frame plate 1 is provided with a butt joint groove 11. The butt joint blocks 4 and the butt joint groove 11 are matched with each other and correspond one-to-one. The I-beam steel frame 3 is set between the two continuous wall frames to ensure the strength of the joint between the two continuous wall frames, and at the same time form a positioning structure to facilitate subsequent fixed connection.

[0027] An extension slot 12 is provided on one side of the frame plate 1. The two sides of the I-shaped steel frame 3 are welded with locking blocks 31 between the connecting strips 4. A slot 32 is provided on one side of the locking block 31. The end of the fiberglass steel column 2 is provided with a fixing component that facilitates automatic adjustment. The fixing component includes a connecting block 5. The connecting block 5 is welded to the end of the fiberglass steel column 2. The end of the connecting block 5 is provided with a slot 51. The slot 51 and the end of the locking block 31 match each other to form the positioning of the I-shaped steel frame 3 at the end of the continuous wall frame, ensuring the stability of the joint between the continuous wall frames.

[0028] A groove 53 is provided on one side of the connecting block 5. A first mounting block 52 is fixed at the opening of the groove 53. The first mounting block 52 is fixed to the connecting block 5 by screws. A pull rod 54 is slidably inserted into the first mounting block 52. An insert block 55 is welded to the end of the pull rod 54. The insert block 55 has a "T" shaped block structure and the side of the end has a rounded block structure. The end of the insert block 55 matches the slot 32.

[0029] A support spring 56 is sleeved on the pull rod 54 between the insert block 55 and the first mounting block 52. The support spring 56 and the insert block 55 form an elastic snap-fit ​​structure, so that the end of the insert block 55 is inserted into the corresponding slot 32, realizing the self-locking of the snap-fit ​​block 31 on the connecting block 5, which facilitates the fixed connection between the I-shaped steel frame 3 and the continuous wall frame.

[0030] At both ends of the I-shaped steel frame 3, limiting blocks 6 are welded on the upper and lower sides. The limiting blocks 6 are in a "C"-shaped block structure, and the ends extend into the extension slots 12. A connecting plate 7 is fitted to the outer side of the limiting blocks 6. Fixing grooves 71 are formed on the inner sides of the connecting plates 7. The ends of the connecting plates 7 are inserted into the extension slots 12 to form the positioning between two diaphragm wall frameworks, ensuring the stability of the diaphragm wall framework.

[0031] A leak-proof limiting component for automatic adjustment is provided between the limiting blocks 6 and the I-shaped steel frame 3. The leak-proof limiting component includes a movable insertion block 62. Accommodation grooves are formed on the sides of the limiting blocks 6 and the I-shaped steel frame 3. A second mounting block 61 is fixed at the opening of the accommodation groove. The second mounting block 61 is fixed to the limiting block 6 by screws. The movable insertion block 62 is in a "T"-shaped block structure and is slidably inserted into the second mounting block 61.

[0032] The end side of the movable insertion block 62 is in an arc block structure and corresponds to the fixing groove 71. The other end of the movable insertion block 62 is welded with a partition plate 63 in the accommodation groove. A return spring 66 is fixedly connected to the other side of the partition plate 63 between the movable insertion block 62 and the accommodation groove. An elastic insertion structure is formed between the return spring 66 and the movable insertion block 62, so that the end of the movable insertion block 62 is inserted into the fixing groove 71, realizing the limiting fixation between the connecting plate 7 and the I-shaped steel frame 3. At the same time, the end of the connecting plate 7 is inserted into the extension slot 12 to form a stepped sealing structure.

[0033] The distance between the partition plate 63 and the accommodation groove is the same as the end length of the movable insertion block 62. A block-shaped airbag 64 is bonded to one side of the partition plate 63 between the movable insertion block 62 and the accommodation groove. A butting airbag 8 is bonded between the upper and lower limiting blocks 6. A connecting pipe 65 is connected between the block-shaped airbag 64 and the butting airbag 8. The depth of the fixing groove 71 is less than the end length of the movable insertion block 62, so that the butting airbag 8 has a certain degree of inflation. When the end of the movable insertion block 62 is squeezed, the movable insertion block 62 moves into the accommodation groove, thereby squeezing the block-shaped airbag 64, and the gas in the block-shaped airbag 64 is transmitted to the butting airbag 8 through the connecting pipe 65. The butting airbag 8 expands and squeezes the connecting plate 7, forming a tight connection between the I-shaped steel frame 3 and the connecting plate 7.

[0034] In actual use, the connecting strip 4 on the I-beam steel frame 3 is inserted into the connecting groove 11 on the frame plate 1 to form a positioning between the I-beam steel frame 3 and the continuous wall frame. At this time, the end of the locking block 31 is inserted into the locking groove 51. During this process, the side of the end of the locking block 31 presses the arc surface of the end of the insert 55, so that the end of the insert 55 is accommodated in the groove 53. When the end of the locking block 31 is in contact with the end face of the locking groove 51, the end of the insert 55 corresponds to the slot 32. Under the elastic force of the support spring 56, the end of the insert 55 is inserted into the corresponding slot 32, realizing the self-locking of the locking block 31 on the connecting block 5, which facilitates the fixed connection between the I-beam steel frame 3 and the continuous wall frame. Then, the end of the connecting plate 7 is inserted into the extension slot 12. During this process, the inner side of the connecting plate 7 presses the movable insert The rounded end of block 62 allows the end of the movable insert block 62 to be accommodated in the receiving groove. At this time, the return spring 66 is compressed, and the movable insert block 62 moves into the receiving groove, thereby squeezing the block-shaped airbag 64. The gas in the block-shaped airbag 64 is transmitted to the abutment airbag 8 through the connecting pipe 65. The abutment airbag 8 expands and squeezes the connecting plate 7, forming a tight connection between the I-shaped steel frame 3 and the connecting plate 7. When the end face of the connecting plate 7 is in contact with the end face of the extension slot 12, the end of the movable insert block 62 corresponds to the fixed groove 71. Under the elastic force of the return spring 66, the end of the movable insert block 62 is inserted into the fixed groove 71, thereby limiting and fixing the connection between the connecting plate 7 and the I-shaped steel frame 3. It has a good anti-seepage function and avoids water seepage at the joint of the continuous wall due to aging of the water-stop iron sheet and traditional steel cage.
