[0001] The present invention relates to the technical field of building construction, and in particular to a single-sided formwork structure for an outer wall of a drop-slab area in a residential basement and a construction method thereof. Background Art

[0002] With the increasing shortage of urban construction land and the increase in land costs, the outer wall of the basement is often close to the foundation pit support structure, leaving no construction operation surface, resulting in a small gap between the foundation pit retaining wall and the outer wall of the basement. The local size from the outside of the basement outer wall to the inside of the retaining pile cannot meet the requirements of the outer wall construction operation, and it is impossible to carry out double-sided formwork reinforcement construction on the outer wall according to conventional methods.

[0003] At present, the pouring construction of the existing basement exterior wall requires the use of single-sided formwork. The single-sided formwork mainly relies on the diagonal braces in a triangular structure to support the formwork body. When the basement floor is sloped, when setting up the side wall formwork in the basement drop-down area, the staff needs to constantly adjust the formwork frame to adapt to the slope angle. However, this process is time-consuming and labor-intensive, increases the labor intensity of the staff, and is prone to quality and safety accidents. In addition, for basement floors with different slopes, the traditional right-angled triangle diagonal braces are not applicable.

[0004] In view of this, it is necessary to design a single-sided formwork structure for the exterior wall of the basement drop-down area of ​​a residential building and a construction method thereof to solve the above problems. Summary of the Invention

[0045] In addition, it also needs to be noted that the term “comprises”, “includes” or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such a process, method, article or device.

[0046] As shown in Figure 1 , Figures 9-11 , the present application provides a single-side formwork structure of the outer wall of the basement drop plate area of a residence, comprising:

[0047] a formwork mechanism, comprising a shaped formwork and a non-shaped formwork arranged below the shaped formwork through a connecting piece;

[0048] a supporting frame arranged at one side of the formwork mechanism;

[0049] A support platform 62 is arranged on the basement floor 70 in the ramp state through a support;

[0050] An adjusting gasket 63 is arranged on the support and between the support platform 62 and the basement floor 70, and the thickness of the adjusting gasket 63 gradually increases in the downhill direction of the ramp;

[0051] A plurality of inclined braces 50 are connected to the support platform 62 at one end and to the support frame at the other end, forming a triangular support structure for supporting multiple parts of the support frame;

[0052] A bottom fixing member is used to fix the bottom of the non-standard formwork.

[0053] Specifically, the standard formwork includes a steel formwork or an aluminum formwork 11, and the non-standard formwork includes any one of a wood formwork, a wood plywood or a bamboo plywood. Specifically, the standard formwork is the aluminum formwork 11, and the non-standard formwork is the wood formwork 12. The aluminum formwork 11 is good in stress and does not have the problem of formwork expansion, and is suitable for formwork erection, but as a building standard part, the bottom of the aluminum formwork 11 is in a horizontal state and is not suitable for erection on a slope. The aluminum formwork 11 and the wood formwork 12 are cooperated with each other, that is, the aluminum formwork 11 is used as the main part of the formwork structure due to its stable stress and no formwork expansion problem, and the wood formwork 12 is used for convenient processing and adjustment to adapt to the slope change of the basement floor 70 and facilitate the erection of the aluminum formwork 11, so that the single-side formwork structure of the present application can avoid the problem of formwork expansion and is suitable for different slopes, and can fully meet the formwork demand of the basement in the ramp state.

[0054] Specifically, the formwork structure is arranged inside the enclosure pile 71, Figure 11 The aluminum formwork 11 is provided with an outer frame 13 away from the enclosure pile 71, a plurality of installation grooves 131 are arranged on both sides of the outer frame 13 in the vertical direction, Figure 2 A first through hole and a limiting member 14 are arranged at the first through hole at the top of the outer frame 13, Figure 4 and a second through hole is arranged at the bottom of the outer frame 13. As shown in Figure 3 The support frame includes a plurality of back battens 21 clamped in the installation grooves 131, a plurality of vertical pressing strips 22 arranged on the side of the back battens 21 away from the aluminum formwork 11 for limiting the horizontal position of the back battens 21, and a vertical frame body connected with the vertical pressing strips 22 through a connecting rod 34. Specifically, two vertical pressing strips 22 are arranged in the horizontal direction, the bottom end of the vertical pressing strip 22 extends to the wood formwork 12 area through the second through hole and is fixed on the wood formwork 12, and the top end of the vertical pressing strip 22 extends upward through the first through hole and is fixed on the vertical position of the vertical pressing strip 22 through the limiting member 14.

[0055] Specifically, as shown in Figure 5As shown, the limiting member 14 is a rectangular frame with an outer size larger than the first through hole size, and an open area is provided on one side of the rectangular frame and fixed by a bolt. When the bolt is locked, the inner size of the rectangular frame is smaller than the sectional size of the vertical pressing strip 22, so that the vertical pressing strip 22 is locked and the vertical orientation of the vertical pressing strip 22 is jointly defined by the top of the outer frame 13 and the limiting member 14.

[0056] Specifically, the connecting member is an L-shaped steel 15, and the aluminum formwork 11 and the wood formwork 12 are fixed by the L-shaped steel 15 and the bolt Figure 6 ).

[0057] Specifically, as shown in the drawings, Figure 7 The basement floor 70 is pre-buried with a plurality of steel pipe members 31. The vertical frame body includes a plurality of connected vertical steels 32 and horizontal steels 33, and the bottom of the vertical steel 32 is inserted and fixed on the steel pipe member 31 Figure 1 ). Exemplarily, the steel pipe member 31 is pre-buried with two, and the corresponding vertical steel 32 is provided with two.

[0058] Specifically, as shown in the drawings, Figure 7 The bottom fixing member includes a cable-stayed member pre-buried on the basement floor 70 and an abutting member abutting against the wood formwork 12 on the side close to the support frame. Exemplarily, the cable-stayed member is a cable-stayed bolt 41, and the abutting member is a triangular steel 42 with a triangular cross section, and the triangular steel 42 is provided with a through slot corresponding to the position of the cable-stayed bolt 41 for facilitating the cable-stayed bolt 41 to pass through. After the cable-stayed bolt 41 passes through the triangular steel 42 and is locked by a nut, the bottom of the wood formwork 12 can be fixed by the bottom fixing member to prevent the wood formwork 12 from swelling during the concrete pouring process Figure 1 ). Since the bottom of the wood formwork 12 is fixed by the triangular steel 42 and the cable-stayed bolt 41, the vertical pressing strip 22 is only used for horizontal orientation limitation of the back lath 21, that is, only the length of the vertical pressing strip 22 needs to be greater than the height of the aluminum formwork 11, so that in the construction of the basement formwork with different slopes, only the inclination angle of the bottom surface of the wood formwork 12 needs to be adjusted to adapt to the slope of the basement, so that the components of the formwork structure of the present application can be reused, and the formwork structure is convenient to construct and has a wide range of applications.

[0059] Specifically, as shown in the drawings, Figures 8-10 The support member is pre-buried on the basement floor 70 and includes a horizontal frame body 611 and vertical screws 612 arranged at four corners of the horizontal frame body 611, and the horizontal frame body 611 is located in the basement floor 70, and the vertical screws 612 vertically extend upward out of the basement floor 70; the support platform 62 is provided with mounting holes corresponding to the vertical screws 612. The adjusting gasket 63 is sleeved on the vertical screw 612, and then the support platform 62 is passed through the vertical screw 612 and fixed by a nut, and the installation of the support platform 62 is completed.

[0060] Exemplarily, the support is provided with two, and the two supports correspond to two vertical steels 32 respectively, so that the support is perpendicular to the aluminum formwork 11 at the plane where the vertical steel 32 is located. The diagonal brace 50 is provided with two groups, each group including three rod bodies, and each group of three rod bodies is installed at one end on the support platform 62 and is connected at the other end to the upper, middle and lower parts of the vertical steel 32 corresponding to the support platform 62 in turn.

[0061] By gradually increasing the thickness of the adjusting gasket 63 in the downhill direction of the slope, the slope surface can be leveled by the adjusting gasket 63, so that the support platform 62 is in a horizontal state, so that the force transmitted by the diagonal brace 50 is decomposed into horizontal force and vertical force during construction, that is, the support composed of the horizontal frame body 611 and the vertical screw 612 is subjected to horizontal and vertical forces, compared with the same specification diagonal fixing member, the support can provide greater fixing force, so as to provide sufficient and stable support force for the diagonal brace 50, overcoming the problem that the triangular steel 42 frame is unstable and inconvenient to construct on the slope in the traditional way.

[0062] The present application constructs the formwork mechanism by the wooden formwork 12 and the aluminum formwork 11, fixes the bottom of the formwork mechanism by the diagonal bolt 41 and the triangular steel 42, levels the support platform 62 by the adjusting gasket 63, and simultaneously laterally supports the formwork mechanism by the diagonal brace 50, overcoming the problem that the triangular steel 42 frame is unstable and inconvenient to construct on the slope in the traditional way, meeting the formwork demand of the basement in the slope state while ensuring the stability of the formwork structure. In addition, the notched mounting back brace 21 and vertical pressing strip 22 are arranged on the formwork to be connected and fixed, avoiding the damage to the outer wall waterproof in the traditional way due to the arrangement of the pull tab.

[0065] S2, mounting the back brace 21 on the mounting slot 131 of the aluminum formwork 11 outer frame 13, and making the vertical pressing strip 22 pass through the first through hole and the second through hole respectively, then fixing the bottom end of the vertical pressing strip 22 on the wooden formwork 12, and fixing the top end of the vertical pressing strip 22 through the limiting piece 14, so as to fix the horizontal position of the back brace 21 by the vertical pressing strip 22;

[0066] S3, the vertical steel 32 is inserted and fixed on the steel pipe 31, and the horizontal steel 33 is installed on the vertical steel 32 to build a vertical frame body; the vertical frame body is fixed with the vertical pressing strip 22 through the connecting rod 34;
