DETAILED DESCRIPTION

The present application is further described in detail below in conjunction with the accompanying drawings.

Example 1

The embodiment of the present application discloses a precast concrete sandwich insulation exterior wall formwork corner anti-deformation structure, which is described by taking a vertical corner as an example, and the corner is a right angle. Referring to FIG2 , the precast concrete sandwich insulation exterior wall formwork corner anti-deformation structure includes an outer blade 1, an insulation board 2, a concrete layer 3 and an inner blade 4, which are arranged in sequence from the outside to the inside, two by two are offset, and have the same length, and are all arranged in the vertical direction.

The outer blade 1 is a concrete slab prefabricated in the factory, and the outer blade 1 is a right-angled plate. A thickened plate 5 is integrally formed at the corner of the outer blade 1. The thickened plate 5 is a triangular prism structure, and the length of the thickened plate 5 is the same as the length of the outer blade 1; the cross-sectional shape of the thickened plate 5 is an isosceles right triangle, and both sides of the thickened plate 5 are against the outer blade 1. The thickened plate 5 and the outer blade 1 form a whole, so that the corner of the outer blade 1 close to the insulation board 2 is two 135° angles, so the thickness of the outer blade 1 at the corner is greater, so the overall strength is higher, and it is not easy to deform, which is helpful for transportation and construction.

Since the outer blade 1 is provided with the thickened plate 5, the shape of the insulation board 2 is also changed accordingly, and the insulation board 2 includes an integrally formed first plate body 21 and a second plate body 22. Two first plate bodies 21 are provided and are perpendicular to each other, and the second plate body 22 is provided between the two first plate bodies 21. The angle between the second plate body 22 and the first plate body 21 is 135°, and the width of the second plate body 22 is the same as the width of the inclined surface of the thickened plate 5, so that the insulation board 2 can be closely fitted with the outer blade 1 provided with the thickened plate 5.

In order to make the construction process easier, referring to Figures 2 and 3, a connecting rod 6 is provided between the insulation board 2 and the outer blade 1. The connecting rod 6 is an angle steel, and is provided along the width direction of the second plate body 22. The connecting rod 6 is passed through the second plate body 22, and both ends of the connecting rod 6 pass through the second plate body 22. The end of the connecting rod 6 passing through the second plate body 22 is embedded in the inner wall of the outer blade 1, so that the end of the connecting rod 6 is fixedly connected to the outer blade 1. Therefore, the connecting rod 6 fixes the insulation board 2 and the outer blade 1 together, making the on-site construction process easier. In addition, it can also play a pulling role on the two side walls of the outer blade 1, further reducing the possibility of deformation of the outer blade 1.

Furthermore, a plurality of connecting rods 6 are provided, and a plurality of connecting rods 6 are evenly spaced in the vertical direction, and a distance between two adjacent connecting rods 6 is 1 m, thereby helping to enhance the pulling effect of the connecting rods 6 on the outer blade 1 .

The implementation principle of Example 1 is as follows: first, a thickened outer blade 1 is prefabricated in the factory, and then an insulation board 2 of a corresponding shape is produced, the insulation board 2 and the outer blade 1 are bonded together, and the end of the connecting rod 6 is fixedly connected to the inner wall of the outer blade 1. Then, the fixed outer blade 1 and insulation board 2 are transported to the construction site, and the outer blade 1 and insulation board 2 are installed at the required position, and the outer blade 1 and insulation board 2 together form an outer formwork; then, the inner blade 4 is installed on the side of the insulation board 2 away from the outer blade 1, and the inner blade 4 and insulation board 2 are arranged at intervals, and then concrete is filled between the inner blade 4 and the insulation board 2, and after the concrete solidifies, a concrete layer 3 can be formed as the main part of the wall. Since the outer blade 1 has been thickened, and the connecting rod 6 has a pulling effect on the outer blade 1, the outer blade 1 is not easy to deform when vibrating after pouring the concrete, which helps to ensure the construction quality.

Example 2

Referring to Figures 4 and 5, the difference between this embodiment and embodiment 1 is that a locking bolt 7 is inserted between the first plate body 21 and the outer blade 1 in this embodiment, a nut is pre-embedded on the inner wall of the outer blade 1, the locking bolt 7 is threadedly connected to the nut, and the head of the locking bolt 7 is pressed against the side of the first plate body 21 away from the outer blade 1, so that the locking bolt 7 can fix the end of the insulation board 2 away from the corner and the outer blade 1 together. A tie assembly 8 is also provided on the insulation board 2, and the tie assembly 8 ties the two ends of the insulation board 2 together, thereby further increasing the strength of the insulation board 2 and the outer blade 1, and reducing the possibility of deformation of the outer blade 1 during construction. There are multiple groups of tie assemblies 8, and they are evenly spaced in the vertical direction, which helps to enhance the tie effect on the insulation board 2 and the outer blade 1.

The tie assembly 8 includes a connecting block 81 and a tie rod 82. Two connecting blocks 81 are provided, and the two connecting blocks 81 are respectively provided at one end of the two first plates 21 away from each other, and the connecting block 81 is located on the side of the first plate 21 away from the outer blade 1. A threaded hole 811 is provided on the connecting block 81, and both ends of the tie rod 82 are provided with external threads adapted to the threaded hole 811. Both ends of the tie rod 82 are respectively threadedly connected to the connecting blocks 81 on both sides, thereby achieving the tie of the two ends of the thermal insulation board 2.

Furthermore, a connecting plate 9 is provided at one end of the first plate body 21 away from the second plate body 22. The connecting plate 9 is in the shape of a long strip, and the length direction of the connecting plate 9 is parallel to the length direction of the first plate body 21. The connecting plate 9 is located on the side of the first plate body 21 away from the outer blade 1, and the connecting plate 9 is fixedly connected to the first plate body 21 by screws. The connecting block 81 is hinged to the side of the connecting plate 9 away from the first plate body 21, and the hinge axis is parallel to the length direction of the first plate body 21. Since the connecting block 81 can be rotated, the installation process of the tie rod 82 is more convenient. When transporting, the tie rod 82 can be removed to reduce the space occupied by the outer blade 1 and the insulation board 2, so that it is convenient to store.

The implementation principle of Example 2 is as follows: after the outer blade 1 and the insulation board 2 connected together are transported to the construction site, the tie rod 82 is threadedly connected to the connecting block 81 at one end, and then the tie rod 82 is rotated so that the tie rod 82 moves away from the other connecting block 81 to provide space for the rotation of the other connecting block 81; then the other connecting block 81 is rotated so that the threaded holes 811 on the two connecting blocks 81 are in a coaxial state, and then the tie rod 82 is rotated in the opposite direction so that the two ends of the tie rod 82 are respectively threadedly connected to the two connecting blocks 81, thereby achieving the tie of the two ends of the insulation board 2. After the installation of the tie rod 82 is completed, the outer blade 1 is installed to the desired position, and then the inner blade 4 is installed and concrete is poured. Under the joint tying action of the connecting rod 6 and the tie rod 82, the influence of the pouring of concrete and the vibration of concrete on the outer blade 1 can be weakened, and the possibility of deformation of the outer blade 1 can be reduced, which helps to ensure the construction quality.

The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
