Technical Field

[0001] This invention relates to the field of aluminum alloy formwork, and particularly to a thermally insulated hollow aluminum formwork structure. Background Technology

[0002] Aluminum alloy formwork has advantages such as being lightweight and high-strength, having good stability, being reusable multiple times, and producing good concrete molding results. It is gradually replacing wooden formwork and large steel formwork as the preferred formwork type in the construction process, and has an increasingly broad application prospect in high-rise and super high-rise construction projects.

[0003] Because aluminum alloy has a high thermal conductivity, it can easily cause heat loss from concrete when the ambient temperature is low. This affects the strength development of concrete during winter construction, is not conducive to concrete curing, and cannot effectively guarantee the construction quality of aluminum alloy formwork during winter construction.

[0004] Currently, the common method for insulation is to cover the outside of aluminum alloy formwork with straw mats. However, the back ribs of the aluminum alloy formwork often lift the straw mats, causing gaps to form between the straw mats and the aluminum alloy formwork. When the straw mats are frozen through, they cannot reduce the heat loss from the concrete, resulting in poor insulation performance of the aluminum alloy formwork, which needs to be improved. Summary of the Invention

[0011] In a preferred embodiment, the present invention may be further configured such that a vacuum insulation plate is provided between the inner template and the outer template, located between the support ring and the support rod.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, a thermally insulated hollow aluminum formwork structure includes a formwork body 1, a rigid thermal insulation liner 2, an mounting ring 3, a back rib 4, and tie bolts 5.

[0020] like Figure 2 , Figure 3 As shown, the template body 1 includes an inner template 11 and an outer template 12 arranged side by side, with a hollow heat-insulating cavity 13 formed between the inner template 11 and the outer template 12.

[0021] like Figure 2 , Figure 3 As shown, the rigid insulation liner 2 includes a support ring 21 and support bars 22, both of which are located on the sides of the inner template 11 and the outer template 12 that are close to each other. The support ring 21 surrounds the mounting hole 15, and the support bars 22 are arranged in a star-shaped pattern around the support ring 21. A vacuum insulation board 14 is provided between the inner template 11 and the outer template 12, located between the support ring 21 and the support bars.

[0022] like Figure 2 , Figure 3 As shown, the support bars 22 on the inner template 11 and the outer template 12 are engaged and locked together. The surface of the support bars 22 is provided with positioning rods 23 and positioning holes 24 that are interlocked to achieve lateral positioning and prevent lateral slippage or movement.

[0023] like Figure 2 , Figure 3 As shown, the mounting ring 3 is located at the outer edge of the back side of the outer template 12, and the back side of the outer template 12 is provided with reinforcing plates 31 located inside the mounting ring 3 in a crisscross pattern. The back rib 4 is arranged laterally on the back side of the outer template 12 and presses against the mounting ring 3.

[0024] like Figure 2 , Figure 3 As shown, a row of mutually aligned mounting holes 15 are vertically arranged in the middle of the inner template 11 and the outer template 12. The tie bolts 5 pass horizontally through the mounting holes 15, and the tie bolts 5 are provided with pads 51 for pressing the back ribs 4.

[0025] When assembling the aluminum formwork structure, the formwork body 1 is vertically erected at the pouring position of the concrete structure, and the inner formwork 11 is brought close together on one side. Then, the back rib 4 is placed horizontally on the back side of the formwork body 1. The tie bolt 5 is then inserted through the mounting hole 15 on the formwork body 1, and the pad 51 on the tie bolt 5 is pressed against the back side of the back rib 4. The tie bolt 5 is then fixed to complete the construction of the aluminum formwork structure.

[0026] When the formwork body 1 is working, due to the hollow insulation cavity 13 structure between the inner formwork 11 and the outer formwork 12, and the vacuum insulation board 14 inside the insulation cavity 13 structure, the thermal break treatment between the inner formwork 11 and the outer formwork 12 is realized, which enhances the insulation effect during the winter construction of concrete, reduces the heat loss of concrete, and improves the construction quality.

[0027] Meanwhile, a rigid heat-insulating liner 2 is provided between the inner formwork 11 and the outer formwork 12. This not only enables the thermal break treatment between the inner formwork 11 and the outer formwork 12, reducing heat loss, but also provides support between the inner formwork 11 and the outer formwork 12, improving the bearing capacity of the inner formwork 11 and ensuring the stable pouring of the concrete structure.

[0028] like Figure 4 As shown, a ring of fasteners 6 is provided at the outer edge of both the inner template 11 and the outer template 12. The cross-section of the fasteners 6 is L-shaped, and they are rectangular when they are interlocked. A fixing screw 61 is provided between a pair of fasteners 6.

[0029] like Figure 4 As shown, a protruding ring 62 is provided at the inner end of the buckle 6, and a groove 63 is provided at the bottom of the inner side for the protruding ring 62 to be inserted. The protruding ring 62 and the groove 63 are distributed on both sides of the fixing screw 61.

[0030] like Figure 4 As shown, a sealing strip 7 is provided in the space enclosed by the inner template 11, the outer template 12 and the fastener 6 to achieve a sealed connection between the inner template 11 and the outer template 12.

[0031] When assembling the template body 1, the inner template 11 and the outer template 12 interlock, and the fastening strips 6 on the inner template 11 and the outer template 12 are inserted and snapped together. Simultaneously, the protruding rings 62 on the fastening strips 6 are embedded in the corresponding grooves 63, achieving both snap-fit ​​fixing and sealing of the connection. Finally, the fixing screws 61 are tightened to secure the inner template 11 and the outer template 12. Then, adhesive is applied to form a sealing strip 7, achieving a stable seal at the connection point between the inner template 11 and the outer template 12.

[0032] like Figure 2 , Figure 5 As shown, the back side of the outer template 12 is provided with an L-shaped bracket 9 for the back rib 4 to be embedded. The bracket 9 includes a rotating shaft 91, a sleeve 92, and a support plate 93.

[0033] like Figure 5 As shown, the rotating shaft 91 is L-shaped and located on the back side of the outer template 12. The sleeve 92 is vertically rotatably connected to the vertical section of the rotating shaft 91. The lower end of the sleeve 92 is provided with a notch 94 for the horizontal section of the rotating shaft 91 to be inserted. The support plate 93 is L-shaped and located on the sleeve 92, and is used to support the back rib 4.

[0034] When the back rib 4 needs to be installed, control the tray 93 to flip to the vertical position. At this time, the tray 93 drives the sleeve 92 to rotate synchronously until the tray 93 is perpendicular to the outer template 12. Then, control the tray 93 to drive the sleeve 92 to move downward, so that the rotating shaft 91 is embedded in the notch 94 on the sleeve 92, realizing the snap-fit ​​limit of the tray 93. At this time, the back rib 4 can be placed in the tray 93 to realize the quick positioning and installation of the back rib 4.

[0035] After the back rib 4 is disassembled, the control plate 93 drives the sleeve 92 to move upward, so that the rotating shaft 91 disengages from the notch 94 on the sleeve 92, releasing the locking limit on the plate 93. Then, the control plate 93 drives the sleeve 92 to rotate in the opposite direction, so that the plate 93 flips to a horizontal state and fits against the back side of the outer template 12, realizing the storage of the bracket 9, which facilitates the stacking, handling and transportation of the aluminum template structure.

[0036] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
