[0035] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] This embodiment provides a folding line external wall corner column formwork reinforcement device, such as Figure 1 As shown, it includes a slope 110 built on one side of an outer wall 11 of a corner 10, and the corner 10 and the slope 110 together form an integrated wall. The corner 10 includes an outer wall 11, an inner wall 12, a top surface 13 and a bottom surface 14, and a bottom template 30 adapted to its structure is constructed on the inner and outer surfaces of the slope 110 and the surroundings of the corner 10, and a sponge layer 20 with the same area as the wall is also provided between the bottom template 30 and the wall. The sponge layer 20 is used to stick and cushion, which can improve the sealing effect when pouring concrete and prevent leakage. A fixed outer corner mold 60 and a fixed inner corner mold 70 are also arranged on the bottom template 30 at the connecting corner between the slope 110 and the outer wall 11 of the corner 10. At the same time, a fixed module 80 is also arranged on the bottom template 30 on the inner wall 12 side of the corner 10. The fixed templates or modules prepared by steel molds at these three positions can further improve the fixed strength, ensure the positioning accuracy of the template at the corner, and prevent deviation. A number of wooden squares 40 and outer steel pipe main ribs 50 are also arranged on the fixed outer corner mold 60, the fixed inner corner mold 70 and the bottom template 30. The matching inclined surface of the slope 110 and the matching surface of the corner 10 are fixedly connected vertically to each other by tension bolts 100, thereby forming a template reinforcement system, which can not only ensure the accuracy of the template position, but also ensure the stability of the entire reinforcement system.

[0037] like Figure 2-4 As shown, the external angle mold 60, the internal angle mold 70, and the mold module 80 are all composite structures made of steel plate materials, and the cross-sections of the external angle mold 60 and the internal angle mold 70 are both constructed as a V-shaped structure, which is a steel mold made of a steel plate with a thickness of 8 mm, mainly used to reinforce the corner where the slope 110 is connected to the outer wall 11, so as to improve the strength and accuracy of the template at this position, prevent the expansion of the mold, and ensure the fixing accuracy and stability of the template here. Among them, the external angle mold 60 and the internal angle mold 70 are directly fixed on the bottom template 30, on which a number of wooden squares 40 are placed, and after the wooden squares are positioned and fixed by the steel pipe main rib 50, the outer layer of the steel pipe main rib 50 is fixedly connected to the bottom template 30 by the tension bolt 100 penetrating the wall and the nut cooperates with the tension bolt 100.

[0038] Since the bevel angle of the slope surface 110 is related to the height of the exterior wall 11, the specific angle of the angle between the fixed exterior corner mold 60 and the fixed interior corner mold 70 is not fixed, and it can be determined based on the actual situation. However, it can be determined that the angle of the fixed exterior corner mold 60 is an obtuse angle, and the angle of the fixed interior corner mold 70 is an acute angle. The side of the fixed exterior corner mold 60 that is mounted on the slope surface 110 is a bevel, and the side that is mounted on the top surface 13 is a horizontal plane; the side of the fixed interior corner mold 70 that is mounted on the slope surface 110 is a bevel, and the side that is mounted on the exterior wall 11 is a vertical downward surface, and a connecting support beam is also provided between the two side surfaces.

[0039] A plurality of wooden squares 40 are provided between the shaping module 80 and the bottom template 30 , and the shaping module 80 is arranged on the vertical wall surface in the inner wall 12 , that is, close to one side of the vertical section of the shaping inner corner mold 70 .

[0040] like Figure 4 As shown, the cross section of the shaping module 80 is constructed as a long strip structure, which can serve as the main rib 50 of the steel pipe, so that the bottom template 30 there is connected with it through the tension bolts 100, and does not affect the template combination configuration of other surfaces. The two side surfaces of the shaping module 80 close to the top and side of the inner wall 12 are set as flat surfaces and are attached to the right-angle corners of the inner wall 12; its bottom surface is also not flat, and its height is adapted to the height of the vertical surface of the inner wall 12.

[0041] The side of the shaping module 80 away from the inner wall of the corner is designed as a multi-section fold line surface structure, including an upper straight section 81 close to the top of the corner, a lower straight section 82 close to the bottom of the corner, and an inclined section 83 connecting the upper straight section 81 and the lower straight section 82, and the angle θ between the inclined section 83 and the lower straight section 82 is 135°. The purpose is to facilitate parallelism with the inclined surface of the wedge block 90 on the inclined surface of the shaping outer corner mold 60, so that the tension bolt 100 can be perpendicular to the two installation surfaces, so that its force strength is maximized and the fixing strength is best.

[0042] Preferably, the horizontal distance between the upper straight section 81 and the inner wall of the corner is greater than the horizontal distance between the lower straight section 82 and the corner, that is, the inclined section 83 is inclined outward from bottom to top, thereby forming an inclined surface parallel to the surface of the wedge block 90, while not affecting the overall strength and installation effect of the wedge block 90. ​​The vertical length of the upper straight section 81 is greater than the vertical length of the lower straight section 82, in order to increase the thickness and length range of the upper straight section 81, so as to improve its overall strength.

[0043] Preferably, a wedge block 80 is provided on the slope surface of the fixed outer corner mold 60, and the outer surface of the wedge block 80 is parallel to the surface of the inclined section 83, and is vertically connected to the surface of the wedge block 80 and the surface of the inclined section 83 by a tension bolt 100, so as to ensure that the tension bolt 100 is vertically stressed. The inclined side surface of the fixed inner corner mold 70 and the outer inclined surface of the slope surface 110, the vertical surface of the fixed inner corner mold 70 and the lower straight section 82 of the fixed module 80, the wedge block 80 on the surface of the fixed outer corner mold 60 and the inclined section 83 of the fixed module 80, and the horizontal surface of the fixed outer corner mold 60 and the bottom surface 14 of the wall corner are vertically connected to each other by the tension bolt 100.

[0044] At the same time, vertical connections are also made by a plurality of tension bolts 100 at the non-corner molds of the slope surface 110 , between the non-corner molds of the outer wall 11 and the inner wall 12 , and between the top surface 13 and the bottom surface 14 .

[0045] A construction method for a broken-line exterior wall corner column formwork, using the reinforcement device as described above, comprises the following steps:

[0046] S1. Build a slope 110 connected to the corner outer wall 11 on one side of the corner outer wall 11, and tie wall column reinforcement.

[0047] S2. After the wall column reinforcement is qualified, a sponge layer 20 composed of sponge strips is laid on the wall surface, and the area of ​​the sponge layer 20 is made the same as the wall area.

[0048] S3. On the sponge layer 20 inside and outside the corner 10 and the slope 110, a bottom template 30 is constructed using a wooden template.

[0049] S4. A fixed outer corner mold 60 and a fixed inner corner mold 70 are also arranged on the bottom template 30 at the corner where the slope 110 and the corner outer wall 11 are connected; and a fixed module 80 is also arranged on the bottom template 30 on the side of the corner inner wall 12.

[0050] S5. Several wooden squares 40 and outer steel pipe main ribs 50 are also arranged on the finalized outer corner mold 60, the finalized inner corner mold 70, the finalized module 80 and the bottom template 30; the opposing inclined surface of the slope 110 and the opposing surface of the wall corner 10 are fixedly connected to each other by the tension bolts 100, and the tension screw 100 and the connected surface are subjected to vertical force.

[0051] S6. After all the formworks have been accepted, pouring of wall concrete begins;

[0052] S7. After the strength of the concrete meets the requirements, the outer steel pipe main rib 50, the wooden square 40, the fixed outer corner mold 60, the fixed inner corner mold 70, the fixed module 80, the bottom template 30, and the sponge layer 20 are removed.

[0053] S8. Repeat the above steps to recycle the reinforcement device again.

[0054] The invention adopts a zigzag exterior corner column template reinforcement device, which is designed by the present invention. By setting a fixed template with different structures at the corner of the wall, the template at the corner is changed from point contact to surface contact, which improves the anti-leakage effect of the template at the corner and solves the problem of mold expansion; and each fixed template is connected and fixed to each other, so that the reinforcement device forms a reinforcement system, improves the reinforcement strength and the stability of the template force at the entire corner, prevents deviation, and ensures the reinforcement accuracy. The present invention also proposes a construction method of a zigzag exterior corner column template using the reinforcement device.
