TECHNICAL FIELD

This structure form brings great difficulties to formwork reinforcement and concrete construction. There is no mature formwork reinforcement form, and some unstandardized reinforcement methods cannot withstand the tension of the concrete itself, which easily causes problems such as formwork expansion and grout leakage, not only affecting the quality of the concrete shape, but also bringing great hidden dangers to the structural strength and anti-seepage function of the concrete.

[0035] The application will be described in detail below in combination with the drawings and specific embodiments.
[0036] The application provides a reinforcing device for a polyline-shaped outer wall corner column formwork, as shown in Figure 1As shown, the outer corner 10 and the slope surface 110 together form an integrated wall body. The outer corner 10 includes the outer wall 11, the inner wall 12, the top surface 13 and the bottom surface 14. The bottom surface of the outer corner 10 and the inner and outer surfaces of the slope surface 110 are provided with the bottom formwork 30 matching the structure thereof. The sponge layer 20 with the same area as the wall body is arranged between the bottom formwork 30 and the wall body. The sponge layer 20 can improve the sealing effect during pouring of the concrete and prevent leakage. The bottom formwork 30 at the connecting corner between the slope surface 110 and the outer wall 11 of the outer corner 10 is further provided with the shaped outer corner form 60 and the shaped inner corner form 70. The bottom formwork 30 on the inner wall 12 side of the outer corner 10 is further provided with the shaped module 80. The shaped formwork or module prepared by the steel formwork at the three positions can further improve the shaping strength, ensure the positioning accuracy of the formwork at the corner and prevent deviation.
[0037] As shown in Figures 2-4 The shaped outer corner form 60, the shaped inner corner form 70 and the shaped module 80 are all combined structures made of steel plates. The cross sections of the shaped outer corner form 60 and the shaped inner corner form 70 are V-shaped structures. The shaped outer corner form 60 and the shaped inner corner form 70 are shaped steel formworks made of steel plates with a thickness of 8 mm. The shaped steel formworks are mainly used for reinforcing the connecting corner between the slope surface 110 and the outer wall 11 to improve the strength and accuracy of the formwork at the position and prevent the formwork from expanding to ensure the fixing accuracy and stability of the formwork. The shaped outer corner form 60 and the shaped inner corner form 70 are directly fixed on the bottom formwork 30. The bottom formwork 30 is provided with the wooden square 40. After the wooden square 40 is positioned and fixed by the outer steel pipe main beam 50, the outer steel pipe main beam 50 is fixedly connected with the bottom formwork 30 by penetrating the wall body by the tensioning bolt 100 and cooperating with the nut.
[0038] The angle of the shaped outer corner form 60 and the shaped inner corner form 70 is not definite and can be determined based on the actual situation. However, it is determined that the angle of the shaped outer corner form 60 is obtuse and the angle of the shaped inner corner form 70 is acute. The side of the shaped outer corner form 60 carried on the slope surface 110 is an inclined surface and the side carried on the top surface 13 is a horizontal plane. The side of the shaped inner corner form 70 carried on the slope surface 110 is an inclined surface and the side carried on the outer wall 11 is a vertical downward surface. A connecting support beam is arranged between the two sides.
[0039] A plurality of wooden blocks 40 are arranged between the shaping module 80 and the base formwork 30, and the shaping module 80 is arranged on the vertical wall surface in the inner wall 12, i.e. on the side of the vertical section close to the shaping inner corner module 70.
[0040] As shown in the figure, the cross section of the shaping module 80 is configured as an elongated structure, which can act as the steel pipe main rib 50, so that the base formwork 30 at this position is connected with the steel pipe main rib 50 through the tie bolt 100, and does not affect the arrangement of the formwork on other surfaces. The two side surfaces of the shaping module 80 close to the top and side of the inner wall 12 are arranged as flat surfaces and are in close contact with the right-angled corner of the inner wall 12; the lower bottom surface of the shaping module 80 is also a flat surface, and the height thereof is adapted to the height of the vertical surface of the inner wall 12. Figure 4
[0041] The side of the shaping module 80 away from the corner of the inner wall is designed as a multi-segment broken 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 included 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-shaped block 90 on the inclined surface of the shaping outer corner module 60, so that the tie bolt 100 can be perpendicular to the two installation surfaces, so that the force strength is maximum and the fixing strength is best.
[0042] Preferably, the horizontal distance of the upper straight section 81 from the side of the corner of the inner wall is greater than the horizontal distance of the lower straight section 82 from the side of the corner, that is, the inclined section 83 is inclined outward from bottom to top, so as to form an inclined surface parallel to the surface of the wedge-shaped block 90, and meanwhile, the overall strength and installation effect of the wedge-shaped block 90 are not affected. The vertical length of the upper straight section 81 is greater than the vertical length of the lower straight section 82, and the purpose is to increase the thickness and length range of the upper straight section 81, so as to improve the overall strength.
[0043] Preferably, the wedge-shaped block 80 is arranged on the inclined surface of the shaping outer corner module 60, and the outer surface of the wedge-shaped block 80 is parallel to the surface of the inclined section 83, and the tie bolt 100 is vertically connected to the surface of the wedge-shaped block 80 and the surface of the inclined section 83, so as to ensure that the tie bolt 100 is vertically stressed. The tie bolt 100 is vertically connected between the inclined side surface of the shaping inner corner module 70 and the outer inclined surface of the inclined surface 110, between the vertical surface of the shaping inner corner module 70 and the lower straight section 82 of the shaping module 80, between the wedge-shaped block 80 on the surface of the shaping outer corner module 60 and the inclined section 83 of the shaping module 80, and between the horizontal surface of the shaping outer corner module 60 and the bottom surface 14 of the corner.
[0044] Meanwhile, the tie bolt 100 is also used for vertical connection between the non-corner module of the inclined surface 110, the non-corner module 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 of a broken line-shaped outer wall corner column formwork adopts the reinforcing device, and comprises the following steps:
[0046] S1, a slope surface 110 connected with the outer wall 11 of the corner is built on the outer wall 11 side of the corner 10, and the wall column steel bars are bound.
[0047] S2, after the wall column steel bars are qualified, a sponge layer 20 composed of sponge strips is first laid on the wall surface, and the area of the sponge layer 20 is the same as that of the wall.
[0048] S3, the bottom layer formwork 30 is built on the sponge layer 20 on the inner and outer sides of the corner 10 and the slope surface 110.
[0049] S4, the shaped outer corner formwork 60 and the shaped inner corner formwork 70 are further arranged on the bottom layer formwork 30 at the connecting corner of the slope surface 110 and the outer wall 11 of the corner, and the shaped module 80 is further arranged on the bottom layer formwork 30 on the inner wall 12 side of the corner.
[0050] S5, the several wooden squares 40 and the outer layer steel pipe main beams 50 are further arranged on the shaped outer corner formwork 60, the shaped inner corner formwork 70, the shaped module 80 and the bottom layer formwork 30; the opposite inclined surfaces of the slope surface 110 and the opposite surfaces of the corner 10 are fixedly connected with each other through the tension bolts 100, and the tension bolts 100 and the connected surfaces are vertically stressed.
[0051] S6, after all the formworks are qualified, the wall concrete is poured;
[0052] S7, after the strength of the concrete meets the requirements, the outer layer steel pipe main beams 50, the wooden squares 40, the shaped outer corner formwork 60, the shaped inner corner formwork 70, the shaped module 80, the bottom layer formwork 30 and the sponge layer 20 are removed.
[0053] S8, the above steps are repeated, and the reinforcing device is recycled.
[0054] The broken line-shaped outer wall corner column formwork reinforcing device designed in the application improves the anti-leakage effect of the formwork at the corner by setting shaped formworks with different structures at the corner and changing the point contact of the formwork at the corner to surface contact, solves the problem of formwork expansion, and connects and fixes the shaped formworks to each other to form a reinforcing system, improve the reinforcing strength and the stability of the stress of the formwork at the corner, prevent deviation, and ensure the reinforcing precision. The application further provides a construction method of a broken line-shaped outer wall corner column formwork adopting the reinforcing device.
