DETAILED DESCRIPTION

[0046] As Figures 1-8 in the figure, a quick construction unsupported cavity structure support system includes a plurality of parallelly arranged side formworks 6, two adjacent side formworks 6 are connected through screw rods 4 and cylinders 5, the screw rods 4 are arranged on the side formworks 6, the cylinders 5 are sleeved on the screw rods 4, the two sides of the cylinder 5 are respectively abutted against the inner sides of the side formworks 6, the two sides of the screw rod 4 are connected through pull ropes 3 and embedded hooks 2, the embedded hooks 2 are arranged on the pouring load plate 1 and / or the ground, the two side formworks 6 and the pouring load plate 1 are connected to form a pouring space of the vertical bracing plate 10.

[0047] For the traditional ship lock construction, due to the existence of a large number of cavity structure, the corresponding scaffold needs to be set up, and the scaffold itself is very time-consuming and laborious due to many components and splicing. The economic is good, which greatly reduces the amount of internal support, and there is a great safety risk in the process of setting up. The process of personnel climbing is inevitable to shake, and the construction efficiency is low. The scheme utilizes the bottom pouring bearing plate 1 and / or the ground as the force basis, and the profile steel can be arranged in the pouring bearing plate 1, which improves the overall strength and is connected with the reinforcing steel of the vertical support plate 10, and the structure is rigid; the pre-buried hook 2 provides a stable hitch point for the pull rope, which ensures the balanced stress of the two sides of the side formwork 6 and prevents the inclination problem. The multiple pull ropes 3 on both sides are locked from different heights, which is safe and reliable. At the same time, the corbel 8 is used as the support, and the prefabricated roof 9 accelerates the process of the overall bottom sealing operation. After the prefabricated roof 9 is hoisted to the corbel 8, the outermost formwork is poured eccentrically, thereby reducing the lateral force of the concrete on the outer formwork and avoiding the problem of formwork 6 slipping. Under the premise of ensuring safety, it is beneficial to speed up the construction progress and avoid the waste of construction time.

[0048] As Figures 9-10 In the preferred scheme, the vertical support plate 10 includes a fixed frame 1003 symmetrically arranged on the upper side, the fixed frame 1003 side wall is connected with the corbel 8, and the multiple corbels 8 are supported at the bottom of the prefabricated roof 9. The prefabricated roof 9 is connected through the pouring bearing plate 1 and the vertical support plate 10.

[0049] During construction, the pre-buried fixed frame 1003 can be used to reserve the welding position of the corbel 8 on the vertical support plate 10, which is convenient for construction. The fixed frame 1003 ensures the structural stability of the corbel, thereby facilitating the prefabricated roof 9 to provide a stable support basis and facilitating the subsequent pouring quality.

[0050] In the preferred scheme, the fixed frame 1003 includes a round rod 1005, the round rod 1005 is provided with a baffle 1004 on both sides, the vertical support plate 10 is provided with an avoiding hole 1002 penetrating through the upper two sides in parallel, the end of the avoiding hole 1002 is provided with a notch 1001, the baffle 1004 is attached to the notch 1001, the round rod 1005 is arranged in the avoiding hole 1002, and the pouring bearing plate 1, the corbel 8, the prefabricated roof 9 and the vertical support plate 10 are connected to form the support platform 7. The pouring bearing plate 1 at the top of the support platform 7 serves as a hitch point for pouring the last vertical support plate 10.

[0051] Through the above setting, the convenience of construction is ensured, and meanwhile, the space of the side formwork 6 can fully meet the installation needs of the fixing frame 1003 in the baffle vertical support plate 10. The upper part of the baffle 1004 of the fixing frame 1003 is provided with a transition rod, and the two transition rods are hoisted on the top of the two side formworks 6 through round rod welding. After the curing is completed, the part protruding from the top of the side formwork 6 is cut off, so that the baffle 1004 with the same height as the top of the vertical support plate 10 is obtained.

[0052] As Figures 11-19 In the preferred scheme, the two sides of the embedded hook 2 are further provided with a locking unit 11, the locking unit 11 includes a vertical plate 1109, a plurality of second through holes 1110 are arranged on the vertical plate 1109, the two sides of the pull rope 3 are respectively provided with a fixing ring 301 and a hook 302, and the two sides of the screw rod 4 are threadedly connected with a position adjusting unit 12.

[0054] In the preferred scheme, the position adjusting unit 12 includes a conical sleeve 1201, the conical sleeve 1201 is threadedly connected with the screw rod 4, the outer side of the conical sleeve 1201 is provided with a hexagonal table 1202, the bottom of the vertical plate 1109 is provided with a square table 1106, the upper part of the embedded hook 2 is provided with a supporting plate 203 on the two sides, the supporting plate 203 is provided with a threaded column 204, and the square table 1106 is threadedly connected with the threaded column 204.

[0055] The position of the conical sleeve 1201 on the screw rod 4 is adjusted by a wrench. The screw rod 4 is provided with square heads at both ends. During installation, the square heads are driven to be installed on the template 6 by the wrench and are locked by the nut 13. Then, when the conical sleeve 1201 on the adjusting and positioning unit 12 is installed, one wrench is used to fix the square head, and the other wrench is used to hold and rotate the hexagonal platform 1202. When the conical sleeve 1201 rotates, the small end of the conical sleeve 1201 penetrates through the inside of the fixing ring 301 and then gradually abuts against the inside of the fixing ring 301, thereby locking the fixing ring 301. Thus, the tensioning rope 3 is stressed. Since there is a certain error during the installation of the cylinder 5 and the screw rod 4 on the template 6, the positions and distances of different screw rods 4 are not completely the same and change to a certain extent. Therefore, the fixing ring 301 can eliminate the above error and adapt to the change of working conditions. Meanwhile, the conical sleeve 1201 can ensure the locking effect according to the above change, and the use is convenient.

[0056] In the preferred scheme, the side of the vertical plate 1109 is further provided with a first holding rod 1114, and the vertical plate 1109 and the first holding rod 1114 are connected through the mounting plate 1108. The mounting plate 1108 is connected through the top rod 1107 and the square platform 1106. The first holding rod 1114 is used to drive the square platform 1106 to rotate.

[0057] After the two ends of the tensioning rope 3 are fixed, the first holding rod 1114 is manually rotated by an operator, so as to change the position of the vertical plate 1109 and tension the tensioning rope 3. The operation is convenient.

[0058] As shown in Figures 20-22 In the preferred scheme, the positioning unit 12 further includes a positioning pad 1203. The positioning pad 1203 is detachably sleeved on the screw rod 4. The outer diameter of the positioning pad 1203 is greater than the outer diameter of the fixing ring 301. The positioning pad 1203 is used to limit the position of the fixing ring 301. The side of the conical sleeve 1201 is further provided with an operation plate 1204. A plurality of fifth threaded holes 1205 are penetratingly arranged on the operation plate 1204. The screw rod 4 is threadedly connected with the fifth threaded holes 1205. The lower part of the operation plate 1204 is provided with a second holding rod 1206.

[0059] When the conical sleeve 1201 on the screw rod 4 corresponding to the uppermost side template 6 of the outermost side template 6 is locked by the conical sleeve 1201, the fifth threaded hole 1205 on the operation plate 1204 and the screw rod 4 can be assembled as needed. When the selected fifth threaded hole 1205 and the conical sleeve 1201 are not coaxial, the conical sleeve 1201 will rotate around the screw rod 4 when the operation plate 1204 is rotated. At this time, the range that can be adjusted by the conical sleeve 1201 is larger, that is, the length change of the tensioning rope 3 can be better adapted to the locking of the fixing ring 301.

[0060] In the preferred embodiment, the embedded hook 2 comprises a U-shaped plate 201, the bottom of the U-shaped plate 201 is symmetrically provided with a bottom plate 202, and the lower side of the U-shaped plate 201 and the bottom plate 202 are embedded in the cast load-bearing plate 1.
