Description

Technical Field

[0001] The invention relates to the technical field of building formwork structures, in particular to a slope roof formwork structure. Background Art

[0002] Sloped roofs, also known as sloping roofs, are common designs for multi-story buildings, ancient buildings, and antique buildings. When constructing a sloping roof, a formwork system needs to be set up to pour concrete or lay tiles to form the roof. The main function of the formwork system is to support the formwork to ensure that the formwork remains stable when pouring concrete or laying tiles, thereby ensuring the construction quality of the sloping roof. The sloping roof formwork system is usually composed of formwork, support parts, and connectors.

[0003] The formwork system of the slope roof is an indispensable part of the construction project, which is related to the construction quality and safety of the slope roof. In actual projects, it is necessary to select appropriate formwork and support materials according to specific project needs and design requirements, and strictly follow the construction process to ensure the construction quality and safety of the slope roof.

[0004] The construction technology of the formwork system is generally to determine the shape and size of the formwork according to the design drawings of the sloping roof, and then install the formwork. The formwork needs to be spliced ​​and fixed according to the requirements of the construction plan to ensure that the splicing is flat and firm; then arrange the supports according to the shape and size of the formwork. The supports need to be evenly distributed to ensure that the formwork is evenly stressed when pouring concrete; then use connectors to connect the formwork and the supports. The connectors need to be firmly fixed to prevent loosening or falling off when pouring concrete; pour concrete in the formwork to form a sloping roof. During the pouring process, attention should be paid to the vibration and plastering of the concrete to ensure that the concrete is dense and flat; after the concrete reaches the designed strength, the formwork is removed. During the removal process, attention should be paid to protecting the quality of the finished product of the sloping roof to prevent damage.

[0005] When the traditional formwork structure is actually used, in the slope roof formwork system structure, one of the double steel tubes of the main keel will be unable to contact the secondary keel, and thus cannot provide support. In this case, the steel tube cannot fit with the secondary keel to bear the force, and the secondary keel only has a single steel tube support. In the actual concrete pouring construction process, it will affect the support effect, and the maximum support force that the formwork structure can provide will be smaller, which will affect the support safety of the formwork structure.

Since the sleeve inside the driving cover is in contact with the transmission disk through the card slot, when the first supporting steel pipe is not in contact with the secondary keel of the formwork system, the driving cover can drive the adjusting rod to rotate through the transmission disk, and the rotation of the adjusting rod can drive the upper lifting pad to move upward. During the upward movement of the lifting pad, the first supporting steel pipe is driven to rise and finally contact the secondary keel of the formwork system to achieve double steel pipe support. After the first supporting steel pipe contacts the secondary keel of the formwork system, it will encounter resistance. At this time, the force of the sleeve in the drive cover and the card slot is not enough to support the adjustment rod to continue to rotate and rise, and then the sleeve will rotate relative to the transmission disk. Under the action of the elastic part, the sleeve hits the vibration sound plate to make a sound. After hearing the sound feedback, the operator can get the information. At this time, it means that the first supporting steel pipe and the secondary keel of the formwork system have been fitted, and the double steel pipe force has been achieved, thereby increasing the maximum supporting strength of the entire formwork structure, meeting the force model calculation conditions, and having higher safety and stability in actual use.

[0030] When this embodiment is actually used, the support height of the first supporting steel pipe 18 can be adjusted under the action of the height adjustment component, so that the first supporting steel pipe 18 and the second supporting steel pipe 19 can simultaneously support the secondary keel 20 of the formwork system. The supporting force is stronger and can meet the conditions for force model calculation, thereby improving the safety and stability of the entire supporting structure.

[0031] The height adjustment component includes an adjustment rod 16 with a thread passing through the bottom wall of the top bracket 9. The top of the adjustment rod 16 is rotatably connected to the lifting pad 11. The lifting pad 11 has a limiting groove 12. The first supporting steel pipe 18 is arranged in the limiting groove 12 of the lifting pad 11. The first supporting steel pipe 18 can be limited by the limiting groove 12.

[0032] The bottom end of the adjusting rod 16 is rotatably provided with a driving cover 17, the adjusting rod 16 extends into the driving cover 17 and is fixedly connected to a transmission plate 24 at the bottom, a slot 25 is provided on the side wall of the transmission plate 24, a vibration sound-generating plate 28 is fixedly provided in the slot 25; the inner wall of the driving cover 17 is fixedly connected to a fixing column 29, a sleeve 26 is slidably sleeved on one end of the fixing column 29 close to the inner wall of the driving cover 17, the sleeve 26 is sleeved on the fixing column 29 on one side of the sleeve 26, and an elastic member 27 is sleeved on the fixing column 29 on one side of the sleeve 26;

[0033] When the first supporting steel pipe 18 is not in contact with the secondary keel 20 of the formwork system, the driving cover 17 can drive the adjusting rod 16 to rotate through the transmission plate 24. The rotation of the adjusting rod 16 can drive the upper lifting pad 11 to move upward. During the upward movement of the lifting pad 11, the first supporting steel pipe 18 is driven to rise and finally contact with the secondary keel 20 of the formwork system to realize double steel pipe support. After the first supporting steel pipe 18 contacts with the secondary keel 20 of the formwork system, it will be subjected to resistance.

[0038] The inner wall of the driving cover 17 is fixedly connected to a fixing column 29, and a sleeve 26 is slidably mounted on one end of the fixing column 29 close to the inner wall of the driving cover 17. The sleeve 26 is mounted on the fixing column 29 on one side of the sleeve 26, and an elastic member 27 is mounted on the fixing column 29 on one side of the sleeve 26. The elastic member 27 can be a spring with telescopic properties or an elastic metal sheet, etc.

[0039] The second positioning rod 22 is fixedly connected to the limiting groove 12 of the lifting pad 11 on both sides below the first supporting steel pipe 18. The second positioning rod 22 is matched with the positioning groove 23 on the first supporting steel pipe 18. The second positioning rod 22 is inserted into the positioning groove 23 on the first supporting steel pipe 18. Under the action of the second positioning rod 22, the first supporting steel pipe 18 can be kept in a stable state, thereby ensuring the stable supporting effect of the supporting structure.

[0040] The partition 10 is fixedly connected to the first positioning rod 21 in the top bracket 9 on both sides below the second supporting steel tube 19 on the side away from the first supporting steel tube 18. The first positioning rod 21 is matched with the positioning groove 23 on the second supporting steel tube 19. The first positioning rod 21 is inserted into the positioning groove 23 of the second supporting steel tube 19 to limit the second supporting steel tube 19 and ensure a stable supporting effect.

[0041] The limiting assembly includes a limiting rod 15, which is slidably arranged at the bottom end of the secondary keel 20 of the formwork system. A positioning column 14 is threadedly penetrated on the limiting rod 15.

[0043] The mounting tube 1 and the lifting column 4 below the mounting rod 5 are connected in a sliding manner to support the upper end of the device. The mounting tube 1 and the lifting column 4 can also use other frame structures with stable supporting effects, such as a disc-type scaffolding. The disc-type scaffolding has a central rod connected by a sleeve and socket, and the horizontal rod and the diagonal rod are inserted into the connecting disk through the rod end buckle joint and connected by a wedge-shaped pin, thereby forming a steel pipe bracket with a structural geometrically invariant system. The top of the scaffold is connected to the mounting rod 5. This scaffolding connection method is firm, the structure is stable, safe and reliable. At the same time, the above-mentioned frame structure with a supporting effect can also use other components with a stable supporting effect.

[0044] Example 3, please refer to Figure 1-Figure 8 The actual application scenario of the formwork structure is that it is used in the process of building a slope roof support structure. The actual principle of use is that during the overall installation of the formwork structure, the formwork system secondary keel 20 below the formwork system template 8 is in contact with the second support steel pipe 19 to achieve support, and the drive cover 17 is rotated at the same time. Since the sleeve 26 inside the drive cover 17 is in contact with the transmission disk 24 through the card slot 25, when the first support steel pipe 18 is not in contact with the formwork system secondary keel 20, the drive cover 17 can drive the adjustment rod 16 to rotate through the transmission disk 24. The rotation of the adjustment rod 16 can drive the upper lifting pad 11 to move upward, and the lifting pad 11 drives the first support steel pipe 18 to move upward during the upward movement. It rises and finally contacts with the secondary keel 20 of the formwork system to realize double steel pipe support. After the first supporting steel pipe 18 contacts with the secondary keel 20 of the formwork system, it will encounter resistance. At this time, the force of the sleeve 26 in the driving cover 17 and the card slot 25 is not enough to support the adjusting rod 16 to continue to rotate and rise, and then the sleeve 26 will rotate relative to the transmission disk 24. Under the action of the elastic member 27, the sleeve 26 hits the vibration sound-emitting plate 28 to make a sound. After hearing the sound feedback, the operator can get the information. At this time, it means that the first supporting steel pipe 18 and the secondary keel 20 of the formwork system have been fitted, realizing the double steel pipe force, thereby improving the maximum supporting strength of the entire formwork structure, and the safety and stability are higher.
