Description

Technical Field

[0001] The utility model relates to the technical field of roof arch plates, in particular to a roof arch plate fixing structure. Background Art

[0002] The roof arch plate structure is mostly thin-walled arch plate, which consists of an upper chord plate and a lower chord plate. A partition is provided between the upper and lower chord plates. During construction, the partition is prefabricated in a centralized manner. When making the roof arch plate, wooden boards are usually used to fix the partition plate to the upper end of the lower chord plate formwork to prevent the partition plate from tilting. Support plates are then fixed on both sides of the partition plate, and then the upper chord plate formwork is placed on the upper end of the support plates. Finally, concrete is poured to complete the production of the roof arch plate.

[0003] However, in the process of using wooden boards to fix the partitions, the wooden boards have a single function and can only fix the partitions. At the same time, with the repeated use of the wooden boards and long-term exposure to the external environment, they are prone to breakage, causing the partitions to tilt or even collapse, which poses certain risks in use. For this reason, we proposed a roof arch plate fixing structure to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a roof arch plate fixing structure to solve the problem that using wooden boards to fix partitions has a single function and poses safety risks.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a roof arch plate fixing structure, comprising a plurality of tensioning platforms symmetrically arranged on a horizontal plane, the tensioning platforms being used to apply prestress to the steel bars, and also comprising a plurality of partition prefabricated components, arch plate prefabricated components and fixing components, the partition prefabricated components being used to prefabricate partitions, the arch plate prefabricated components being used to prefabricate arch plates, the arch plate prefabricated components comprising an upper template, a lower template, prestressed steel bars and a plurality of support plates, the lower template being arranged at the upper end of the horizontal plane, the prestressed steel bars being arranged in the lower template, and both ends of the prestressed steel bars being They are all connected to the adjacent tensioning table. The partition is arranged at the upper end of the prestressed steel bar. The fixing assembly includes a positioning frame, a bidirectional screw, a fixing plate and two clamping plates. The positioning frame is arranged at the upper end of the lower template, the bidirectional screw is arranged on the inner wall of the positioning frame, and the outer wall of the bidirectional screw is symmetrically provided with a moving block. The two clamping plates are respectively arranged at one end of the moving block extending out of the positioning frame. A rotating part is provided at the end of the bidirectional screw that rotates through the positioning frame. Bolts are symmetrically provided on the outer wall of the positioning frame. The fixing plate is arranged between the two bolts. The support plate is symmetrically provided on the outer wall of the partition, and the upper template is provided at the upper end of the support plate.

[0006] The beneficial effects of this solution are as follows: when in use, the positioning frame is first placed above the lower formwork, and the spacing between the partitions is determined. Then the staff rotates the rotating part to make the bidirectional screw rotate in the positioning frame, so that the clamping plate moves to the middle of the positioning frame along with the moving block, and then the lower formwork is clamped by the clamping plate to fix the positioning frame. At this time, the clamping plate can not only fix the positioning frame, but also reinforce the left and right side walls of the lower formwork to prevent leakage when the lower formwork is poured with cement. The clamped clamping plate can apply a certain pre-tightening force to the lower formwork, thereby counteracting the volume expansion generated during the solidification process of concrete and preventing the lower formwork from deformation. When the positioning frame is fixed, the staff places the partition above the prestressed steel bar and between the two bolts. The staff then fixes the fixing plate to the positioning frame through nuts, thereby completing the fixation of the partition and preventing it from tilting.

[0007] Preferably, as an improvement to the roof arch plate fixing structure, the partition prefabricated assembly includes a template and a steel mesh. The template is arranged at the upper end of the horizontal surface, the steel mesh is arranged inside the template, and both ends of the steel mesh are connected to the adjacent tensioning table.

[0008] The beneficial effects are: the construction efficiency can be greatly improved by prefabricating the partitions. At the same time, the steel mesh is tensioned by the tensioning pedestal to generate prestress, thereby improving the bearing capacity and stability of the partitions, ensuring that the partitions can maintain good structure and function during long-term use.

[0009] Preferably, as an improvement to the roof arch plate fixing structure, it also includes a ring beam and a full-height bracket. The full-height bracket is arranged on one side of the inner side of the ring beam. A mounting plate is provided on the top of the full-height bracket to form a mounting plane. The arch plate prefabricated components are arranged on the mounting plane and the upper end of the ring beam. A reinforced gutter is provided on the outer wall of the ring beam, and several tensioning platforms are provided on the inner bottom of the reinforced gutter.

[0010] The beneficial effect is: by prefabricating the roof arch panels on the installation plane, the tower crane can be avoided from lifting the roof arch panels. At the same time, the full-floor bracket does not cover the entire roof area, so that the process can be interspersed in advance, which saves construction time, achieves early completion, and reinforces the gutter for the installation of the tensioning table.

[0011] Preferably, as an improvement to the roof arch plate fixing structure, a plurality of installation grooves are symmetrically opened on the upper end of the ring beam, a jack is provided in each installation groove, and a sliding trolley is provided on the upper end of the ring beam.

[0012] The beneficial effects are: the roof arch plate can be raised by the jack, and the roof arch plate can be moved to the designated position by the sliding trolley, which greatly improves the construction efficiency.

[0013] Preferably, as an improvement to the roof arch plate fixing structure, the rotating member includes a turntable and a handle, the turntable is arranged at one end of the bidirectional screw that rotates through the positioning frame, and the handle is rotatably arranged at the end of the turntable away from the positioning frame.

[0014] The beneficial effect is that the staff can rotate the bidirectional screw more efficiently through the cooperation between the handle and the turntable, thereby improving the fixing efficiency of the positioning frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Example 1

[0022] Example 1 is basically as shown in the attached Figure 1-3 As shown, Figure 1 The roof arch plate fixing structure shown in the figure includes several tensioning platforms 1 symmetrically arranged on the horizontal plane, the tensioning platforms 1 are used to apply prestress to the steel bars, and also include several partition prefabricated components, arch plate prefabricated components and fixing components 2. The partition prefabricated components are used to prefabricate partitions. The partition prefabricated components include templates 13 and steel mesh 14. The template 13 is placed at the upper end of the horizontal plane. The steel mesh 14 is laid in the template 13, and the left and right ends of the steel mesh 14 are connected to the adjacent tensioning platforms 1. Of course, multiple partition prefabricated components can be set between two corresponding tensioning platforms 1 for tensioning together, thereby reducing the number of tensioning platforms 1. The arch plate prefabricated components are used to prefabricate arch plates, such as Figure 2As shown, the arch plate prefabricated assembly includes an upper template 3, a lower template 4, prestressed steel bars 5 and several support plates 6. The lower template 4 is placed at the upper end of the horizontal surface. The prestressed steel bars 5 are laid inside the lower template 4, and both ends of the prestressed steel bars 5 passing through the lower template 4 are connected to the adjacent tensioning platform 1. Several partitions are vertically placed on the upper end of the prestressed steel bars 5, as shown in FIG. Figure 3 The fixing assembly 2 shown includes a positioning frame 7, a bidirectional screw 8, a fixing plate 9 and two clamping plates 10. The positioning frame 7 is placed on the upper end of the lower template 4. The bidirectional screw 8 is installed on the inner wall of the positioning frame 7 for transverse rotation. The outer wall of the bidirectional screw 8 is symmetrically threaded with a moving block 11. The two clamping plates 10 are respectively provided at one end of the moving block 11 extending out of the positioning frame 7. The end of the bidirectional screw 8 that rotates through the positioning frame 7 is provided with a rotating member. The rotating member includes a turntable 18 and a handle 19. The turntable 18 is fixedly installed on the end of the bidirectional screw 8 that rotates through the positioning frame 7. The handle 19 is rotatably provided at the left end of the turntable 18. The lower end of the positioning frame 7 is symmetrically fixed with bolts 12, and the fixing plate 9 is provided between the two bolts 12. Figure 2 The support plates 6 shown are symmetrically fixedly installed at the left and right ends of the partition. The support plates 6 are arranged in a U shape to limit the side walls of the upper template 3. The upper template 3 is placed on the upper end of the support plates 6.

[0023] The specific implementation process is as follows:

[0024] When the fixing plate 7 is fixed, the staff will place the partition 4 above the prestressed steel bar 5 and place it between the two bolts 12. The staff will then fix the fixing plate 9 to the positioning frame 7 to prevent it from tilting.

[0025] Example 2

[0026] The principle of embodiment 2 is roughly the same as that of embodiment 1, except that: Figure 4The roof arch plate fixing structure shown in the figure also includes a ring beam 15 and a full-height bracket 20. The full-height bracket 20 is fixedly installed on one side of the inner part of the ring beam 15. The upper end of the full-height bracket 20 is fixedly installed with a mounting plate to form a mounting plane 16. Of course, a number of horizontal bars can be set horizontally on the upper end of the full-height bracket 20 to resist the force applied by the tensioning table 1 when processing the steel mesh 14 and the prestressed steel bars 5, thereby improving the stability of the ring beam 15. The arch plate prefabricated components are arranged on the mounting plane 16 and the upper end of the ring beam 15. The partition prefabricated components are arranged on the mounting plane 16 and the upper end of the ring beam 15. The components only need to be constructed on a flat ground and can be flexibly set up on the construction site. The outer wall of the ring beam 15 is fixedly installed with a reinforced gutter 21. Of course, a bracket can be set under the reinforced gutter 21 to improve the stability of the reinforced gutter 21. Several tensioning platforms 1 can be detachably installed on the inner bottom of the reinforced gutter 21, and the tensioning platforms 1 on both sides correspond to each other one by one. Several installation grooves 17 are symmetrically opened on the upper end of the ring beam 15, and a jack is placed in each installation groove 17. A sliding trolley slides on the upper end of the ring beam 15.

[0027] In Example 2, the full-floor bracket 20 does not completely occupy the space inside the ring beam 15, but only occupies one side of the ring beam 15, so that construction can be carried out on decoration and installation projects such as the ground, walls, ceilings, doors and windows, so that the work processes can be interspersed in advance, so as to save construction time and achieve early completion. When the roof arch plate is completed, the staff can raise the roof arch plate through the jack in the installation groove 17, and move the sliding trolley at the upper end of the ring beam to the bottom of the roof arch plate, and then the staff will place the roof arch plate on the upper end of the sliding trolley, and finally move the roof arch plate to the designated position by moving the sliding trolley.
