Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to an inner membrane pressure bar system for an aqueduct. Background Technology

[0002] An aqueduct is an elevated water channel that transports water across rivers, valleys, depressions, and roads. It is commonly used for irrigation and water conveyance, as well as for flood control and sediment removal. Large aqueducts can also be navigable. Aqueducts are mainly constructed with materials such as masonry, concrete, and reinforced concrete. Formwork engineering is a crucial part of the concrete construction of U-shaped aqueducts. After the inner formwork of the U-shaped aqueduct is assembled, the inner membrane reinforcement has become an important component.

[0003] In current water conservancy projects, the reinforcement of the inner formwork of aqueducts is achieved by using channel steel bracing on steel formwork. This method requires the placement of a large number of channel steels within a small area inside the U-shaped aqueduct, which not only affects the efficiency of the workers in reinforcing the inner formwork but also directly affects the concrete pouring. After the inner formwork of the U-shaped aqueduct is assembled, the problem of anti-buoyancy of the inner formwork is not effectively addressed, resulting in defects such as floating formwork, bursting formwork, and grout leakage, which directly affect the appearance quality of the inner concrete. Therefore, there is an urgent need for an inner formwork pressure bar system for aqueducts. Utility Model Content

[0004] The purpose of this utility model is to provide an inner membrane pressure bar system for aqueducts, which solves the problem in the prior art where the inner membrane reinforcement of aqueducts is carried out by using channel steel bracing on steel formwork. This method requires a large number of channel steels to be laid in a small area inside the U-shaped aqueduct, which not only affects the efficiency of the inner membrane reinforcement for workers. With the U-shaped aqueduct inner membrane pressure bar system, the system can be assembled off-site, and after all the assembly is completed, the pressure bar system can be hoisted to the construction surface in one go, which facilitates the pouring of concrete aqueducts.

There are three spiral strut structures 5, and the spiral strut structures 5 and connecting rod 6 are fixedly connected by support seats 11. Each spiral strut structure 5 includes a first mounting seat 501, an adjusting rod 502 is engaged on the outer side of the first mounting seat 501, a threaded sleeve 503 is sleeved on the outer side of the adjusting rod 502, and a support sleeve 504 is connected to the end of the threaded sleeve 503. Adjusting rods 502 are provided on the inner sides of both ends of the support sleeve 504. The ends of the two adjusting rods 502 are respectively provided with a first mounting seat 501 and a second mounting seat 505, and the adjusting rod 502 is fixedly connected to the inner steel template 7 through the second mounting seat 505. The support sleeve 504 and the adjusting rod 502 are connected by screws... The threaded sleeve 503 and threaded movable connection, the pressure bar system of the inner membrane of the U-shaped aqueduct is assembled off-site. This involves adjusting the overlapping area of ​​the support sleeve 504 and the adjusting rods 502 on both sides by screwing the support sleeve 504 and the threaded sleeve 503. Then, based on the distance between the connecting rod 6 and the inner steel template 7, appropriate adjustments are made. After adjustment, the spiral strut structure 5 is fixed to the connecting rod 6 via the support base 11. After all assembly is completed, the pressure bar system is hoisted to the construction surface in one go. First, the inner steel template 7 of the aqueduct is assembled and fixed with bolts. Then, the transverse connecting rod 6 is fixed together with the transverse connecting piece 10 of the steel template, ensuring that the dimensions between the inner membranes of the U-shaped aqueduct remain unchanged. Subsequently, four sets of precision-rolled threaded steel 3 and I-beams 1 are connected in parallel with the transverse connecting rod 6. Together, the I-beam 1 and the connecting rod 6 are fixed together with precision-rolled nuts 4, forming a whole. To ensure that the inner template does not float or burst, three support rods 2 are welded between the I-beam 1 and the connecting rod 6. After all the above installations are completed, three spiral strut structures 5 are installed and fixed to the inner steel template 7 through the second mounting base 505, which provides support for the inner steel template 7 of the U-shaped aqueduct. After all the steel reinforcement of the aqueduct is tied and accepted, the pressure bar system of the inner membrane of the U-shaped aqueduct is hoisted to the construction surface in one go. The longitudinal spacing of the pressure bar system is 1.5m, and it is connected to the outer steel template of the aqueduct to form a whole. This method greatly reduces the construction cost while speeding up the construction progress and improving the appearance quality of the finished product after pouring.

[0023] During use, the pressure bar system for the inner membrane of the U-shaped aqueduct is assembled off-site. This involves adjusting the overlapping area of ​​the support sleeve 504 and the adjusting rods 502 on both sides by screwing on the support sleeve 504 and threaded sleeve 503. This adjustment is then made according to the distance between the connecting rod 6 and the inner steel template 7. After adjustment, the spiral strut structure 5 is fixed to the connecting rod 6 via the support base 11. Once all assembly is complete, the pressure bar system is hoisted to the construction surface in one go. First, the inner steel template 7 of the aqueduct is assembled and fixed with bolts. Then, the transverse connecting rod 6 is fixed together with the transverse connecting piece 10 of the steel template, ensuring that the dimensions between the inner membranes of the U-shaped aqueduct remain unchanged. Subsequently, four sets of precision-rolled threaded steel bars 3 and I-beams 1 are connected in parallel with the transverse connecting rods 6, and precision-rolled nuts 4 are used to fix the I-beams 1 and connecting rods 6 vertically. To ensure that the inner formwork does not experience floating or bursting, three support rods 2 are welded between the I-beam 1 and the connecting rod 6. After all the above installations are completed, three spiral strut structures 5 are installed and fixed to the inner steel formwork 7 via the second mounting base 505, providing support for the inner steel formwork 7 of the U-shaped aqueduct. After all the reinforcing bars of the aqueduct are tied and accepted, the pressure bar system of the inner membrane of the U-shaped aqueduct is finally hoisted to the construction surface in one go. The longitudinal spacing of the pressure bar system is 1.5m, and it is connected to the outer steel formwork of the aqueduct to form a whole. The formwork of this pressure bar system can be spliced ​​off-site as a whole, and after assembly, it is hoisted to the working surface as a whole. When dismantling the formwork, it is also removed as a whole in one go. This method greatly reduces construction costs while speeding up the construction progress and improving the appearance quality of the finished product after pouring.
