Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to an assembled bridge steel template. Background Art

[0002] As the name implies, prefabricated bridges are different from traditional on-site construction methods such as steel bar binding and concrete pouring. For prefabricated bridges, the substructure of the bridge includes piers, abutments and cap beams, and the superstructure includes box beams, plate beams and T beams. After being processed and formed in the prefabricated component factory, they are transported to the construction site for hoisting and splicing into the main body of the bridge. The various components of the bridge are mechanically connected through pre-embedded holes, pre-embedded steel bars and connecting devices processed during the prefabrication production process. Grouting is performed using the grouting sleeves in the components so that the concrete fully fills the pores between the components to achieve overall strengthening.

[0003] At present, the box beam needs to be completed with steel formwork during the prefabrication process. Generally, it is necessary to design a suitable formwork according to the size of the box beam, and then pour concrete in the formwork. After it solidifies, it can be demoulded to obtain the prefabricated box beam. In order to complete the demoulding work more conveniently, it is generally necessary to apply a release agent on the inner wall of the formwork before pouring. Currently, many water-based release agents need to be mixed with water before use;

[0004] However, the existing prefabricated bridge steel molds are often unable to automatically complete the spraying of release agents. Most of them are applied manually, which is time-consuming and labor-intensive, and is prone to omissions, affecting the production efficiency of box girders. Secondly, water-based release agents cannot be stirred at any time, and are prone to precipitation if not used for a long time, thus affecting the quality of the release agent. Utility Model Content

[0005] The utility model aims to solve one of the technical problems in the related art to at least a certain extent. To this end, one purpose of the utility model is to provide an assembled bridge steel formwork, which solves the inconvenience of manually applying a release agent during the prefabrication of box girders, improves the application efficiency and quality of the release agent, and can effectively prevent the release agent from being diluted with water during the application process, thereby affecting the subsequent quality.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 , an assembled bridge steel formwork, comprising a formwork body 1, a spraying frame 2 and a release agent box 4;

[0027] Side plates 6 are symmetrically arranged on both sides of the top of the template body 1, and slide grooves 19 are opened on the inner sides of the two sets of side plates 6. Pulleys 12 are movably installed at the bottom of both ends of the spraying frame 2, and the pulleys 12 are movably installed at the inner bottom of the slide grooves 19;

[0028] Among them, two sets of pulleys 12 are arranged at both ends of the spraying rack 2, and the two sets of pulleys 12 are arranged horizontally. By arranging two sets of pulleys 12, the sliding of the spraying rack 2 in the slide groove 19 can be more stable, thereby preventing the spraying rack 2 from shaking during the movement;

[0029] The spraying frame 2 is slidably installed on the inner side of the template body 1 through the pulley 12. The reduction motors 10 are symmetrically embedded and installed on both sides of the top of the spraying frame 2. The driving gears 11 are driven and installed on the outer output shafts of the two sets of reduction motors 10. The top of the inner wall of the slide groove 19 is provided with a first tooth groove 20, and the driving gear 11 and the first tooth groove 20 are meshed with each other;

[0030] Among them, the reduction motor 10 adopts a slow-speed high-torque motor, which can provide greater power to ensure that the spraying frame 2 can be driven to move as a whole;

[0031] In addition, support trusses 3 are provided on both sides of the template body 1. The support trusses 3 are welded from multiple groups of steel pipes. The support trusses 3 are used to support the template body 1 to ensure the overall stability of the template body 1.

[0032] Secondly, a power supply line 17 is fixedly installed on the other side of the top of the spray rack 2. The power supply line 17 is electrically connected to the reduction motor 10 and the liquid pump 22. The power supply line 17 adopts a standard three-phase line to ensure safety.

[0033] In this embodiment, the driving gear 11 located on the first tooth groove 20 can be driven to rotate by starting the reduction motor 10, and the two groups of reduction motors 10 need to drive the two groups of driving gears 11 to rotate relative to each other, thereby driving the spray rack 2 located on the inner side of the two groups of side panels 6 to move horizontally. At this time, the spray rack 2 can also be located on the inner side of the template body 1 and move horizontally, which is beneficial to the subsequent spraying of the release agent.

[0034] Reference Figure 1 A release agent box 4 is fixedly installed on the top of the spray frame 2, and a liquid pump 22 is fixedly installed on the bottom of the other side of the release agent box 4. One side of the input end of the liquid pump 22 is placed inside the release agent box 4, and a liquid infusion pipe 15 is fixedly installed on the output end of the liquid pump 22. A plurality of groups of nozzles 16 are embedded in the outer wall of the bottom of the spray frame 2, and the liquid infusion pipe 15 is connected to each group of nozzles 16 through a plurality of branch pipes.

[0035] The nozzle 16 is an atomizing nozzle, the output end of the nozzle 16 is toward the inner wall of the template body 1, and multiple groups of nozzles 16 are evenly distributed on the outer wall below the spraying frame 2, thereby ensuring that the release agent can be evenly sprayed on the inner wall of the template body 1;

[0036] In this embodiment, the release agent box 4 is filled with water-based release agent. During the movement of the spray frame 2, the liquid extraction pump 22 can be synchronously turned on to extract the release agent inside the release agent box 4, and then transport it to each group of nozzles 16 through the infusion tube 15. Finally, the release agent is evenly sprayed on the inner wall of the template body 1 through each group of nozzles 16, thereby completing the release agent application work before pouring.

[0037] Reference Figure 1-4 A rotating rod 13 for stirring transmission is movably installed inside the demoulding agent box 4, one end of the rotating rod 13 penetrates the demoulding agent box 4 and is placed outside the demoulding agent box 4, and a driven gear 14 is fixedly installed on one end of the rotating rod 13 extending from the demoulding agent box 4, a rotating shaft frame 7 is fixedly installed on the top of the spraying frame 2 and close to the side of the driven gear 14, a rotating shaft 8 is movably installed in the rotating shaft frame 7, a second tooth groove 21 is opened on the top of the side plate 6, and transmission gears 9 are symmetrically installed at both ends of the rotating shaft 8, and two sets of transmission gears 9 are respectively meshed with the driven gear 14 and the second tooth groove 21;

[0038] Among them, stirring blades 18 are fixedly welded around the outer wall of the rotating rod 13 and located inside the demoulding agent box 4. The number of stirring blades 18 is four groups, and the four groups of stirring blades 18 are installed on the outer wall of the rotating rod 13 in a cross shape;

[0039] Secondly, the size of the transmission gear 9 is larger than that of the driven gear 14, so that the driven gear 14 can rotate two times for every rotation of the transmission gear 9, thereby increasing the rotation speed of the driven gear 14 and the rotating rod 13, so that the rotating rod 13 can drive the stirring blade 18 to rotate and stir at a high speed in the release agent box 4, thereby ensuring the stirring quality;

[0040] In addition, a gear box 5 is fixedly installed on the side wall of the release agent box 4 and close to the driven gear 14. The driven gear 14 and the transmission gear 9 meshing at the bottom thereof are both arranged inside the gear box 5, and the rotating rod 13 is movably penetrated through the outer wall of one side of the gear box 5. The gear box 5 can effectively protect the driven gear 14 and the transmission gear 9.

[0041] In this embodiment, when the spray rack 2 is moving and spraying, its transmission gear 9 can be located on the second tooth groove 21 and rotate synchronously, thereby driving the rotating shaft 8 and the transmission gear 9 on the other side to rotate, and the transmission gear 9 on the other side can drive the driven gear 14 and the rotating rod 13 to rotate. At this time, the stirring blade 18 on the outer wall of the rotating rod 13 can be located inside the release agent box 4 to rotate and stir, thereby ensuring that the water-based release agent inside the release agent box 4 is evenly mixed to prevent precipitation from affecting the performance of the release agent.

[0042] Working principle: before using the template body 1, it is necessary to apply the release agent on the inner wall. At this time, the reduction motor 10 and the liquid pump 22 can be started. The reduction motor 10 can drive the driving gear 11 to rotate in the first tooth groove 20, thereby driving the pulleys 12 on both sides of the spray frame 2 to slide in the slide groove 19. At this time, the spray frame 2 can be located on the inner side of the two groups of side plates 6 and move horizontally at a uniform speed. At this time, the liquid pump 22 can extract the release agent from the release agent box 4, and then transmit it to each group of nozzles 16 through the infusion pipe 15, and finally spray it to the inner wall of the template body 1 through the nozzle 16 to complete the spraying work. During this spraying process, the movement of the spray frame 2 can drive the transmission gear 9 located on the second tooth groove 21 to rotate, and randomly through the transmission gear 9 on the other side, it can drive the small-sized driven gear 14 and the rotating rod 13 to rotate at high speed, causing the stirring blade 18 to rotate at high speed in the release agent box 4 to complete the stirring of the release agent, thereby preventing the release agent from settling and affecting the quality.
