Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of building exterior walls, and in particular to an exterior wall formwork protection integrated system and an exterior wall formwork protection integrated board. Background Art
[0002] The formwork-retaining integrated board is composed of an inner reinforcement layer, a ribbed insulation layer, a bonding layer, a non-combustible insulation transition layer, and an outer reinforcement layer. It is factory-produced and composited to provide thermal insulation and eliminate the need for dismantling the external formwork during cast-in-place concrete construction. This integrated board represents a building energy-saving and structural integration technology, combining building insulation with wall enclosure functions. It meets current building energy-saving standards without the need for additional testing measures, achieving energy-saving benefits by balancing insulation and structural integrity.
[0003] There are two main existing solutions for achieving thermal insulation with integrated formwork panels: one involves placing insulation panels with wire mesh inside the exterior formwork, which are then connected to the concrete wall through inserts during concrete pouring. After the formwork is removed and plastered, the exterior wall decoration is applied. The other involves constructing the concrete body first, then attaching the insulation panels, adding mesh and nailing for reinforcement, and then applying the wall decoration. Both solutions require the erection of scaffolding or hangers, involving wet work such as plastering and painting, posing high-altitude operations and fire hazards. There have also been quality incidents involving insulation layer detachment.
[0004] In order to solve the above problems, the Chinese invention patent (authorized) with application number CN201610084156.1 discloses an exterior wall system and construction method of cast-in-place prefabricated disassembly-free integrally assembled insulation exterior formwork, including an inner formwork, a prefabricated exterior wall composite insulation formwork, and wall reinforcement, which are spliced together to form a prefabricated integrally assembled insulation exterior formwork and wall reinforcement; the cast-in-place shear wall is cast on-site with the prefabricated integrally assembled insulation exterior formwork and the inner formwork as support; the prefabricated integrally assembled insulation exterior formwork is fixedly installed on the prefabricated exterior wall insulation exterior formwork frame, and the prefabricated exterior wall insulation exterior formwork frame and the prefabricated integrally assembled insulation exterior formwork are hoisted as a whole on the outside of the wall reinforcement and correspond to the inner formwork on the inside of the wall reinforcement, and a tension bolt assembly is provided in the wall reinforcement that transversely penetrates the wall reinforcement, the prefabricated exterior wall insulation exterior formwork frame and the inner formwork. However, this technology still has the following defects when used: during installation, the formwork integral panels on the inner and outer sides need to be connected by a tension bolt assembly, and the metal rod of the tension bolt directly passes through the outer formwork integral panel, the middle cast-in-place concrete wall, and the outer formwork integral panel. After the wall solidifies, the end of the tension bolt assembly protruding from the wall is generally cut to be flush with the wall, and the remaining part of the tension bolt assembly remains in the wall. However, this will cause the wall to form a "thermal bridge" connecting the indoor and outdoor environments at the installation node of the tension bolt when in use, reducing the thermal insulation effect of the formed wall.

[0053] When the upper and lower adjacent mold-retaining integrated unit plates are spliced together, the lower first protrusion 101 can be inserted into the upper first slot 102 .
[0054] The top of the lightweight mortar layer 5 is integrally connected with a second protrusion 501 that protrudes upward and extends in the front-to-back direction. The left-right width of the second protrusion 501 is smaller than the left-right width of the lightweight mortar layer 5; the bottom of the lightweight mortar layer 5 is provided with a second protrusion 502 corresponding to the second protrusion 501 above and below; the second slot 502 of the mold-retaining integrated unit plate located at the bottom is filled with a second filling strip 23.

The right side wall of the receiving groove 1301 can limit the maximum angle of downward rotation of the pull rod 15. The angle at which the pull rod 15 can rotate relative to the steel cage fixing part 12 is less than or equal to 90 degrees. In this embodiment, the angle at which the pull rod 15 can rotate relative to the steel cage fixing part 12 is 90 degrees. Both the steel cage fixing part 12 and the pull rod 15 can be slid into the embedded pipe 10.
[0058] The length of the movable rod 13 is shorter than that of the embedded tube 10. A cuttable push-pull rod is connected to the left end of the movable rod 13.

The annular internal thread kit 19 is movably mounted on the screw rod 18 and is threadedly connected to the screw rod 18. The outer wall of the annular internal thread kit 19 is fixed with multiple limiting rods 20 arranged at intervals around the circumference. The rotation limiting structure includes multiple slots 1001 provided on the inner wall of the left end of the embedded pipe 10. The left end of the slot 1001 and the side away from the bottom of the slot are both open structures. The end of the limiting rod 20 away from the annular internal thread kit 19 slides within the slot 1001.
[0061] In order to prevent the movable rod 13 from rotating when the screw rod 18 rotates, Figure 7 As shown, a guide bar 14 extending in the left-right direction is provided on the inner wall of the embedded pipe 10, and a left-right transparent sliding groove is opened on the side wall of the movable rod 13, and the guide bar 14 is slidably provided in the sliding groove.

[0064] The portion of the steel cage fixing member 12 extending into the casting cavity and the tie rod 15 are pre-embedded in the cast-in-place concrete 9. After the left and right formwork retaining integrated panels and the steel cage 8 are connected by the tie rods 15 on both sides, the excess portion of the screw rod 18 extending out of the embedded pipe 10 is cut off, and the embedded pipe 10 is filled with sealing concrete to seal and fix the steel cage fixing member 12 in the embedded pipe 10.
[0065] In order to further improve the separation resistance and structural strength between the layers of the mold-protecting integrated unit panel, the bonding reinforcement layer 4 includes a steel mesh, and a plurality of evenly distributed arc-shaped through holes are opened on the thermal insulation layer 3; arc-shaped reinforcing ribs 24 are passed through the gaps in the steel mesh and the arc-shaped through holes.

[0067] Then, by turning the handle 21, under the action of the linear motion formed by the screw rod 18 and the annular internal threaded sleeve 19, the movable rod 13 and the pull rod 15 are pushed through the gap of the steel cage 8 into the casting cavity, so that the pull rod 15 naturally hangs down to the inside of one of the transverse bars 801 of the steel cage 8.
[0068] Then, the screw rod 18 is rotated, and under the guidance of the guide bar 14 , the movable rod 13 moves linearly outward, and the pull rod 15 is hooked on the inner side of the transverse rib 801 .
[0069] When the pull rods 15 on both sides are hooked on the left and right sides of the steel cage 8 respectively, the cast-in-place concrete 9 is poured in the pouring cavity. After the cast-in-place concrete 9 solidifies, the excess screw rods 18 are cut off, the embedded pipe 10 is sealed with concrete, and the steel cage fixing piece 12 is sealed and fixed in the embedded pipe 10 to form a Figure 2 The structure shown.
