The concrete component is composed of 24 cross sections of sawtooth water pattern connected to a circle, and the center angle of each sawtooth concrete fold is 15°. Based on the above-mentioned concrete component of spiral rising water pattern, the embodiment provides a concrete component template device of spiral rising water pattern, as shown in Figure 2 and Figure 3 The support assembly is connected between the sliding assembly and the template assembly.

[0032] It should be noted that the orientation of the embodiment is referenced to the actual construction orientation.

[0033] The sliding assembly includes a track 8. In order to adapt to the structure of the concrete component of spiral rising water pattern, the track 8 is provided with a circular cross section, and the track 8 is laid from the ground of the underground first floor to the top plate of the underground first floor, which is located at the symmetry axis position of the above-mentioned concrete component. The outer periphery of the track 8 is provided with a groove 9, and the groove 9 spirally rises along the outer surface of the track 8, and the angle of the spiral rising of the groove 9 is consistent with the angle of the spiral rising of the concrete component.

[0034] As shown in Figure 3 The outer side of the track 8 is sleeved with an inner sleeve 10, and the inner diameter of the inner sleeve 10 is slightly larger than the outer diameter of the track 8. The inner wall of the inner sleeve 10 is provided with a protrusion, which can be clamped into the groove 9 of the track 8, so as to ensure that the inner sleeve 10 can spirally rise when it is lifted along the track 8. The outer side of the inner sleeve 10 is provided with a lifting hook, and the lifting hook is connected with a cable 12 of a winch. The inner sleeve 10 is moved upward by the winch.

[0035] The outer side of the inner sleeve 10 is provided with an outer sleeve 11, and the inner diameter of the outer sleeve 11 is slightly larger than the outer diameter of the inner sleeve 10, so as to ensure that the outer sleeve 11 can slide along the inner sleeve 10. The outer sleeve 11 can be provided with one or more, and in order to ensure the stability of the formwork, at least two outer sleeves 11 are provided.

[0036] The embodiment takes two outer sleeves 11 as an example for detailed description, as shown in Figure 3 The two outer sleeves 11 are sequentially arranged along the axial direction of the inner sleeve 10, and the inner sleeve 10 and the two outer sleeves 11 are respectively connected with a set of traction device.

[0037] The support assembly includes a plurality of support rod assemblies, and the number of the support rod assemblies is the same as the number of the cross sections of the concrete component; as shown in Figure 2 The support rod assemblies are arranged in a radial manner, and the included angle between adjacent groups of support rod assemblies is the same as the center angle of the circular corner of the sawtooth concrete fold, for example, 24 groups of support rod assemblies are provided, and the included angle between adjacent groups of support rod assemblies is 15°.

[0038] The strut assembly includes a main strut 6 and a sub-strut 7, the length of the sub-strut 7 being less than that of the main strut 6.

The sub-strut 7 is connected at one end to the outer sleeve 11 and at the other end to the main strut 6. Figure 3 Figure 3 The connection of the main strut 6 and the sub-strut 7 is hinged, specifically, one end of the main strut 6 is connected to the inner layer of the folding formwork 2 through a third hinge 13, the other end of the main strut 6 is connected to the inner sleeve 10 through a fourth hinge 15; one end of the sub-strut 7 is connected to the main strut 6 through a fifth hinge 14, the other end of the sub-strut 7 is connected to the outer sleeve through a sixth hinge 16. Moving the outer sleeve 11 along the inner sleeve 10 causes the sub-strut 7 to drive the main strut 6, changing the angle between the main strut 6 and the outer sleeve 11, not only can make the formwork assembly away from or close to the sliding main axis (the axis of the track 8), change the cross-sectional radius of the concrete member; but also by changing the different angles between the front and rear two groups of main struts 6 and the inner sleeve 10, the angle between the formwork assembly and the sliding main axis can be set.

[0039] The formwork assembly includes a plurality of folding formworks, the number of folding formworks being the same as the number of cross sections of the concrete member. The folding formworks are sequentially connected in the circumferential direction to form a closed structure, and the adjacent groups of folding formworks are connected through trusses 5. The folding formworks and the trusses 5 are hinged through first hinges 4.

With the change of the angle between the main strut 6 and the outer sleeve 11, the angle between the mutually connected formworks and the cross-sectional radius of the concrete member also changes.

[0042] Figure 2 The folding formwork has a certain length along the sliding direction, which is about 1.2m, which can ensure that the concrete poured from the front end has enough time to harden and form when sliding out from the rear end. Figure 3

[0043]

[0044] ​​​The template assembly of the embodiment can ascend along the track 8, and can complete pouring of the entire length-direction spiral ascending waterline type concrete member, thereby saving the number of templates, avoiding a large amount of positioning and setting-out work and assembling work of bulk templates, and improving construction efficiency.

[0045] Embodiment two:

[0046] The embodiment provides a construction method of a spiral ascending waterline type concrete member template device, adopts the template device of the embodiment one, and comprises the following steps:

[0047] After the template assembly is assembled, the inner sleeve pipe 10 is pulled by the winch at the front end of the track 8, and then the support assembly and the template assembly are driven to ascend and advance along the track 8 by the inner sleeve pipe 10. Meanwhile, the hand-operated hoist at the top end of the outer sleeve pipe 11 and the inner sleeve pipe 10 is pulled, so that the included angle between the main support rod 6 and the outer sleeve pipe 11 is increased, and the cross-sectional radius of the corresponding template system is gradually increased. The concrete is poured in the space between the inner sleeve pipe 10 and the outer sleeve pipe 11, and the hardened concrete is discharged from the back of the template.

[0048] The advancing speed of the template assembly along the track 8 is closely related to the concrete strength, air temperature and the like, and the concrete discharged from the template should not collapse due to too low strength, and should not be adhered to the template due to too high strength. The pulling speed of the outer sleeve pipe 11 should also be matched with the advancing speed of the template assembly along the track 8, so that the concrete construction cross section is consistent with the design cross section.

[0049] The above only describes the preferred embodiments of the application and is not used to limit the application. For those skilled in the art, the application can have various modifications and changes. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the application should be included in the protection scope of the application.
