The embodiment of the utility model provides a template fixing device, figure 1, 2 are according to the utility model discloses template fixing device's schematic structure diagram. Referring to fig. 1 and 2, the device at least comprises an anchor bar 1, a nut 2 and a screw rod 3; one end of the anchor bar 1 is fixedly connected with the dam face 6, and the other end of the anchor bar 1 is provided with an open bent part; the nut 2 is annular and can be hung and connected with the bent part of the anchor bar 1; one end of the screw rod 3 is in threaded connection with the nut 2, and the other end of the screw rod 3 penetrates through the template 7 and is fixed with the template 7. In some embodiments, the bending part is U-shaped, the bending part is conveniently hooked with the ring nut 2, the template fixing device adopts the ring nut 2, the ring nut 2 is hooked with the bending part, the connection is convenient, multi-angle convenient hooking can be realized, the requirements on the position and precision of punching on the template are low, repeated punching for many times is avoided, the underwater installation efficiency is high, meanwhile, the ring nut 2 is in threaded connection with the lead screw 3, welding is not needed, the time and labor cost for prefabricating the drag hook on land are saved, concretely, the time for underwater welding is saved, the bolting strength is guaranteed, the original processing mode needs to connect the lead screw with a reinforcing rib behind the template through electric welding, time and labor are wasted, the welding part is frequently disengaged due to stress, an unstable connection relation exists between the anchor rib and the template, the anchor rib cannot pull the template, further the template 7 expands and deforms during pouring, and the nut 2 is compared with the welded drag hook and the U-shaped ring, the force is higher, the template is not easy to pull-off, and the pouring engineering is good application prospect is achieved, the problem that the underwater fixing and the installation of the high template 7 is difficult to underwater fixing and the pull rib pulling during the underwater installation is solved.

It should be noted that when installing the steel formwork 7 protruding out of the dam 6 and the clearance between the formwork 7 and the original dam 6 is small, an anchoring device adapted to the working condition is needed. The existing anchoring device divides the anchor bar 1 into two sections, one section is anchored on the dam face 6 in advance, the other section penetrates the formwork 7 to be connected with the first section after the formwork 7 is in place, and the corresponding construction process is as follows: punching a dam facing 6, embedding the annular anchor bars 1, and exposing the annular anchor bars 1 out of the dam facing 6 for a certain distance according to actual working conditions; manufacturing a template 7 drag hook on land, wherein the drag hook is formed by welding deformed steel bars and a screw rod; after the template 7 is put down in place, a diver refers to the position of the annular anchor rib 1 on the dam surface 6, and holes are formed in the corresponding position of the template 7; a diver holds the draw hook by hand, hooks the annular anchor bar 1, penetrates the end of the screw rod out of the template 7, pads the gasket 5, and tightens the nut 2 to prevent the screw rod from falling off from the opening of the template 7; the U-shaped steel bar is welded at the head of the nut 2, and the other section of the U-shaped steel bar is welded on the vertical beam of the template 7, so that the U-shaped steel bar is ridden on the vertical beam, and the acting force received by the anchor bar 1 can be transmitted to the vertical beam. However, the above construction process has the following problems, and alignment is difficult: the anchoring holes on the template 7 are holes which are formed in the positions of the annular anchor bars 1 reserved on the original dam facing 6 by a diver through visual and groping underwater, the hole forming positions are not necessarily accurate, and if the position deviation between the hole opening and the annular anchor bars 1 is too large, the screw rods after being hooked cannot penetrate through the template 7 necessarily, and holes may need to be punched again; the installation takes time: the underwater hole forming position of the template 7 cannot be guaranteed to be accurate, the lead screw is difficult to penetrate out, if the lead screw cannot penetrate out, the template 7 needs to be punched again, after the nut 2 is tightened, a U-shaped ring needs to be welded at the head of the nut 2, the other end of the U-shaped ring is welded on a vertical beam of the template 7, and underwater welding consumes working hours; the disassembly is time-consuming: the gasket 5, the nut 2 and the U-shaped ring are sequentially arranged outside the template 7, and the U-shaped ring is welded and fixed with the main beam of the template 7, so that the U-shaped ring is cut firstly when the template 7 is disassembled, and then the nut 2 gasket 5 is loosened, so that the screw rod can be cut to be flush with the outer surface of the template 7; the quality is difficult to guarantee: the bearing capacity of the welding position is low, the stress is easy to break, a section of welding position is arranged between the hook and the screw rod, the nut 2 and the U-shaped steel bar are also welded and fixed, the lateral pressure of the concrete on the template 7 is larger during concrete pouring, once the fixing device is broken, the fixing effect on the template 7 disappears, and the template is easy to expand and even run. The template fixing device provided by the embodiment of the utility model adopts the ring nut 2, thereby saving the time and labor cost for prefabricating the drag hook on land, needing no welding and being directly used after purchasing; the underwater installation is convenient, the repeated punching work is avoided, and the underwater installation efficiency is high; compared with a welded draw hook and a U-shaped ring, the nut 2 has higher supporting force and is not easy to break; demolish when template 7 only need press close to mainboard steel sheet department lead screw cut off can, the good operation of electricity oxygen cutting can guarantee moreover that the cutting is thorough.

Further, the other end of the screw rod 3 penetrates through the template 7, a nut 4 is connected to the end through threads, and a gasket 5 is arranged between the nut 4 and the template 7. Optionally, a channel steel is further arranged between the gasket 5 and the formwork 7, and two flange plates of the channel steel clamp reinforcing ribs (namely vertical beams) of the formwork 7, so that the transverse shaking is prevented, and the stability is improved; the channel steel is strip-shaped, and two flange plates of the strip-shaped channel steel clamp two sides of the reinforcing rib of the template 7; the channel steel is provided with an opening, the screw rod 3 sequentially penetrates through the template 7, the opening and the gasket 5 and is in threaded connection with the nut 4, and the width of the opening is smaller than the size of the gasket 5; the opening is long. Through setting up the channel-section steel, cushion up gasket 5 for the lead screw in the channel-section steel outside, tighten nut 4, prevent that the lead screw from 7 trompils of template come off, transmit the effort that anchor bar 1 received for template 7 through the channel-section steel piece and erect the roof beam.

The working process of the template fixing device is as follows:

1) Punching a dam facing 6, embedding anchor bars 1, and exposing the anchor bars 1 out of the dam facing 6;

2) After the template 7 is put down in place, a diver refers to the position of the anchor rib 1 of the dam surface 6 and holes are formed in the corresponding position of the template 7;

3) The diver hangs the nut 2 on the anchor bar 1, and the screw rod penetrates from the template 7 and is screwed with the nut 2;

4) Fixed lead screw 3 and template 7, optional, the channel-section steel of installing a division rectangular hole additional at the lead screw afterbody, and the both sides of erecting the roof beam are cliied to two flange boards of channel-section steel, and gasket 5 is filled up for the lead screw in the channel-section steel outside, and tight nut 4 prevents that the lead screw from 7 trompils of template from droing, passes through the groove steel sheet with the effort that anchor bar 1 received and transmits for 7 perpendicular roof beams of template.
