Specific implementation mode

[0025] Next, the technical solutions in an embodiment of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] Please refer to Figures 1 - 10 :

[0027] A three-sided steel mold integral arched skeleton, the arched skeleton includes a plurality of arched bottom die units 1, arched upper die units 2, a plurality of arc-shaped lower templates 25, a plurality of cover plates 4, and an arched auxiliary top template 3. The arched auxiliary top template 3 is spaced above the uppermost upper template 22. Both the bottom die unit 1 and the upper die unit 2 include an arched upper template (12; 22) provided at the top and two vertical side templates (11; 21) integrally connected to the two ends of the arched upper template (12; 22) respectively.

[0028] Wherein, the ends of the two side templates 21 of the upper die unit 2 are also integrally connected with inward arc-shaped template segments (23; 24) respectively. The two arc-shaped template segments (23; 24) are located on the same arc line. In addition, the upper die unit also includes an arc-shaped lower template 25. The arc-shaped lower template 25 is spliced with the two arc-shaped template segments (23; 24) to form an arch shape. The arc-shaped template segments are provided to facilitate the installation of the lower template, and at the same time, it is also beneficial for the lower template and the side template to form an integral body.

[0029] The bottom die units 1 and the upper die units 2 are arranged at intervals in rows and columns. The arched bottom die units 1 are located at the bottom layer of the arched skeleton, and the arched upper die units 2 are located above the uppermost arched bottom die units 1.

[0030] The cover plate 4 is covered between adjacent side templates, between adjacent upper templates 22 and auxiliary top templates 3, and between the lower template 25 and the upper template (12; 22).

[0031] The interval between two adjacent side formworks forms the main runner for concrete pouring. The interval between the adjacent upper formwork 22 and the auxiliary top formwork 3 and the interval between the adjacent upper formwork and the lower formwork form the branch runners for concrete pouring that communicate with the main runner.

[0032] The cross-sections of the side formworks (11; 21), the upper formworks (12; 22), the lower formwork 25 and the auxiliary top formwork 3 are all roughly in a C shape, and their upper and lower bottom plates are provided with corresponding first through holes (111; 211; 251; 31). Among them, the upper bottom plate is connected to the cover plate 4 through the first through holes (111; 211; 251; 31) on it and bolts, and the lower bottom plate is connected to the ground through the first through holes (111; 211; 251; 31) on it and bolts to help fix the formworks. The lower formwork 25 and the arc-shaped formwork segments (23; 24) can also be connected through a connecting piece with through holes.

[0033] Since the arched bottom die unit 1 has rigidity, in order to shape the two side formworks 11, a detachable fixing strip 5 is provided between the two side formworks 11 through the first through holes 111 and bolts.

[0034] The cover plate 4 is in a shape similar to an inverted "L". The two top surfaces of the cover plate 4 are provided with second through holes 41. The cover plate 4 has a square shape and an arc shape, and is connected and fixed to the side formworks (11; 21), the upper formworks (12; 22), the lower formwork 25 and the auxiliary top formwork 3 through the second through holes 41 and bolts.

[0035] A carrying rod 42 is provided between the two side surfaces of the cover plate 4 to facilitate the installation of the cover plate 4.

[0036] Since the bottom die unit 11, the upper die unit 2, the lower formwork 25 and the auxiliary top formwork 3 of the arched framework are all prefabricated integrally in the factory, thus, not only can the integrity of the entire framework be provided, but also the construction efficiency can be improved, the project cycle can be shortened, and the project can be put into use faster.

[0037] In order to form a flat surface before pouring the arched framework, the present utility model also provides an overall flattening structure. The overall flattening structure is used to achieve overall flattening of the three-sided steel formwork integral arched framework. The overall flattening structure includes a number of longitudinal pressing blocks 6 and a number of transverse pressing strips 7. The longitudinal pressing blocks 6 are arranged on the cover plate between two adjacent side formworks, and a number of transverse pressing strips 7 are arranged at intervals between adjacent longitudinal pressing blocks 6.

[0038] The longitudinal pressing block is an I-beam, with pressing block screw holes 61 and pressing block through slots 62 arranged alternately on both sides. The pressing block through slots 62 are arranged on the top side edges of the longitudinal pressing block to facilitate the installation and disassembly of the transverse pressing strip 7. During installation, the transverse pressing strip 7 enters the slot of the longitudinal pressing block 6 from the pressing block through slot 62, moves the transverse pressing strip 7 to the lower part of the adjacent pressing block screw hole 61, and fixes the transverse pressing strip 7 through bolts, the pressing block screw hole 61, and the pressing strip screw hole 71. During this process, gaskets can be used as needed; during disassembly, loosen the bolts and take out the transverse pressing strip 7 from the pressing block through slot 62.

[0039] Fixed screw holes 63 are also provided at both ends of the longitudinal pressing block to facilitate the fixation of the longitudinal pressing block 6 to the ground.

[0040] Working principle:

[0041] See the appendix Figure 6 The arched skeleton of the two-layer structure, appendix Figure 7 The arched skeleton of the three-layer (multi-layer) structure:

[0042] Before construction, first fabricate the bottom die unit 1, upper die unit 2, lower template 25, accessory top template 3, cover plate 4, longitudinal pressing block 6, and transverse pressing strip 7 in the factory; then, engrave the base groove on the slope, and then transport all the fabricated templates to the construction site. Since the bottom die unit 1, upper die unit 2, lower template 25, and accessory top template 3 are all prefabricated integrally in the factory, the construction efficiency is improved, the project cycle is shortened, and the project can be put into use faster.

[0043] During construction, install the bottom die unit 1 in the bottommost base groove, install the upper die unit 2 in the base groove above the bottom die unit 1, splice the lower template 25 with two arc template segments (23; 24), then install the accessory top template 3 above the uppermost upper die unit 2, and then fix the cover plate 4 between adjacent side templates through bolts, between adjacent upper templates and the arched accessory top template 3, and between the lower template 25 and the upper template (12; 22) adjacent to the lower template 25 to form a mutually connected pouring channel, and pour through the pouring port 8 provided at the connection (set other pouring ports at appropriate positions as needed).

[0044] Since the surface of the arch-shaped framework cannot be in a plane after the installation of the arch-shaped framework, a longitudinal pressing block 6 is provided on the cover plate between two adjacent side templates. The two ends of the longitudinal pressing block 6 can be fixed to the ground through fixing screw holes 63 and screws. A plurality of transverse pressing strips 7 are arranged between two adjacent longitudinal pressing blocks 6. The transverse pressing strips 7 can enter the slots of the longitudinal pressing blocks 6 through the pressing block through slots 62, and the transverse pressing strips 7 are fixed by adjacent pressing strip screw holes 61 and bolts. In this way, the entire arch-shaped framework forms a flat surface under the action of the overall flattening structure, which not only improves the quality and reliability of the project, extends the service life of the structure, but also has an overall aesthetic appearance.

[0045] The above are only the embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
