Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated component production, in particular to a U-shaped sheet pile mould. Background Art

[0002] At present, U-shaped prestressed concrete sheet piles are produced by the pre-tensioning method. Tensioning pedestals are provided at both ends of each production line. A fixing device for prestressed steel bars is installed on the tensioning pedestal at one end, and a prestressed steel bar tensioning machine is installed on the tensioning pedestal at the other end. The length of the sheet piles produced each time is different. The tail end of the steel bar passes through the baffle at the tail of the mold and is connected and fixed by a sleeve and a clip. Similarly, the steel bar at the head end passes through the fixed connecting plate and is connected to the tensioning equipment. During the production process, a certain amount of excess steel bars needs to be reserved to facilitate the connection and disassembly of the steel bars, sleeves and clips. This results in serious waste of steel bars, especially when long molds are used to produce short piles. The steel bars at the head end need to be connected to the tensioning equipment, which will cause the length of the prestressed steel bar to be much longer than the pile length. After the pile is formed, a long section of prestressed steel bars needs to be cut off, resulting in serious waste of raw materials. Utility Model Content

[0030] Below with reference to the embodiment and the attached Figures 1 to 10 , the technical solution of the utility model is further elaborated.

[0031] Example 1

[0032] A U-shaped sheet pile mold, comprising: a drawing mold 1 and a connecting piece 3, the drawing mold 1 comprising a bottom template 11, end templates 12 arranged on both sides of the bottom template 11, and two side templates 13 arranged between the end templates 12, the side templates 13 and the bottom template 11 are rotatably connected, the end template 12 is fixedly arranged on the bottom template 11, a through hole 121 is provided on the end template 12, a fixed sleeve 2 is provided in the through hole 121, the connecting piece 3 is used for tensioning the device and the U-shaped sheet pile. The connection between the sheet pile reinforcement cages, the connecting member 3 is a connecting sleeve, and the connecting sleeve includes a first accommodating cavity 42 located in the middle, reinforcement holes 43 extending to both ends, and a first T-shaped mounting groove 41 connected to the reinforcement holes 43. The prestressed main reinforcement 51 of the U-shaped sheet pile reinforcement cage is engaged in the corresponding first accommodating cavity 42 through one of the first T-shaped mounting grooves 41, and the connecting reinforcement 52 is engaged in the corresponding first accommodating cavity 42 through the other first T-shaped mounting groove 41. The connecting reinforcement 52 is connected to the tensioning device.

[0033] like Figures 1 to 10 As shown, in the actual use of the present invention, a prestressed tendon 51 of appropriate length is selected according to the U-shaped sheet pile actually produced, one end of which is fixed to the connecting sleeve 2 of one of the end templates 12, and the other end is fixed to the mounting T-slot 41 of the connector 3. Then, a connecting rib 52 of appropriate length is selected, one end of the connecting rib 52 is fixed to the mounting T-slot 41 of the connector 3, and the other end is fixed to the fixing sleeve 2 of the other end template 12. A tensioning platform is provided on the outside of the end template 12, and the tensioning platform is connected to the connecting rib 52. The prestressed tendon 51 is tensioned by the tensioning platform to meet production needs.

[0034] The prestressed tendons adopt a segmented structure. When the length of the U-shaped plate produced is shorter than the length of the drawing die 1, prestressed tendons 51 of appropriate length can be selected according to the actual length of the U-shaped plate and combined with the connecting tendons 52 for production. After production is completed, the connecting tendons 52 can be taken out from the connecting piece 3 to avoid the problem that when the U-shaped sheet pile is shorter than the length of the drawing die 1, the prestressed tendons 51 are too long, resulting in the need to cut off a long section of prestressed steel bars after the pile is formed, causing serious waste of raw materials.

[0035] The stress ribs 51 are connected by fixing the sleeves 3 to replace the original sleeves and clips at both ends of the mold, which facilitates the connection between the stress ribs and the tensioning equipment, is simple and convenient to operate, and saves time and effort.

[0036] Example 2

[0037] The difference between Example 2 and Example 1 is that the connecting member 3 is a connecting sleeve, which includes a first connecting member 31 and a second connecting member 32. The first connecting member 31 and the second connecting member 32 are both provided with a first T-shaped mounting groove 41, a first accommodating cavity 42 and a rib outlet hole 43 that is connected to the first T-shaped mounting groove 41. The first T-shaped mounting groove 41 of the first connecting member 31 is provided with a prestressed rib 51, and the first T-shaped mounting groove 41 of the second connecting member 32 is provided with a connecting rib 52. The connecting member 3 is combined with two groups of sleeves, which facilitates processing and effectively reduces production costs.

[0038] As a further preferred embodiment, the distance between the head of the first T-shaped mounting groove 41 and the end of the sleeve is a, and the distance between the end of the first accommodating cavity 42 and the end of the sleeve is b, satisfying the quantitative relationship: a>b, preventing the swaged head of the steel bar from slipping out of the through groove during installation.

[0039] Example 3

[0040] The difference between Example 3 and Example 2 is that an external thread 311 is provided at one end of the first connecting member 31, and an internal thread 321 matching the external thread 311 is provided at one end of the second connecting member 32. The two sets of sleeves are connected by threads, and the connection method is simple, which is convenient for disassembly and assembly during use.

[0041] Example 4

[0042] The difference between Example 4 and Example 3 is that a first limiting hole 312 is provided through the external thread 311 of the first connecting member 31, and a second limiting hole 322 is provided through the external thread 311 of the second connecting member 32. Limiting pins can be inserted into the first limiting hole 312 and the second limiting hole 322. The threaded connection and the limiting pin increase the connection strength between the two sleeves and prevent the two sleeves from loosening during the tensioning process.

[0043] Example 5

[0044] The difference between Example 5 and Example 1 is that a second T-shaped mounting groove 21 , a mounting thread 22 and a second accommodating cavity 23 are provided in the fixing sleeve 2 to facilitate the fixation of the prestressed tendon 51 .

[0045] Example 6

[0046] The difference between Example 6 and Example 1 is that a blocking bolt is provided at the end of the fixing sleeve 2, and the blocking bolt is used to limit the fixing sleeve 2 to prevent the steel bar from being pulled off and injuring people.

[0047] Example 7

[0048] The difference between Example 7 and Example 6 is that a guide seat 24 is provided on a side of the fixing sleeve 2 close to the through hole 121 to facilitate the installation of the fixing sleeve 2 .

[0049] As a further preferred embodiment, the distance between the head of the second T-shaped mounting groove 21 and the end of the fixed sleeve 2 is c, and the distance between the end of the second accommodating cavity 23 and the end of the fixed sleeve 2 is d, satisfying the quantitative relationship: c>d.
