[0002] In the traditional method, the way of implanting steel bars and welding tie bolts in the diaphragm wall is not positioned, the on-site template opening is messy, the verticality and flatness of formwork making are not easy to control, and the appearance quality of the concrete surface is poor. The on-site formwork making workload is large, and the cross-construction with welding affects the progress. Each floor construction takes about 15 days, and the progress is slow. The messy on-site opening makes the template can only be used once, resulting in high costs. It is not easy to control the verticality and flatness during template installation, the influence of the joint on the concrete surface is difficult to solve, and the waterproofing at the steel bar implantation part is difficult to guarantee.

[0003] To solve the above problems, a patent document with the publication number of "CN205777530U" discloses a support for single-sided formwork of a basement, including a steel panel, double-channel steel back ribs, connecting fasteners, supports, transverse connecting steel pipes, rear legs, moving casters, front legs, embedded parts devices, secondary ribs, bases, adjusting screw rods, outer connecting rods, channel steel pads, connecting nuts and embedded part bolts.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment: Refer to Figures 1 - 3 A support for single-sided formwork in the basement shown, which includes a steel panel 1 and channel steel back ribs 2 fixed on the back side of the steel panel 1. A plurality of support units are provided on the side of the channel steel back ribs 2 away from the steel panel 1. The support units include:

[0027] Two triangular support frames 3 rotatably connected by a rotational connection assembly 8, and the rotational connection assembly 8 is located in the middle of the sides of the two triangular support frames 3 away from the channel steel back ribs 2;

[0028] Movable support columns 4. There are two movable support columns 4 and they are installed at one end of the two triangular support frames 3 close to the channel steel back ribs 2. Both the upper and lower ends of the movable support columns 4 are rotatably connected to the two ends of the triangular support frames 3 through connecting parts respectively;

[0029] Connection fastener installation holes 401 for installing connection fasteners are provided on the movable support columns 4, and the movable support columns 4 are fixedly connected to the channel steel back ribs 2 by connection fasteners in a tensioning manner;

[0030] The back sides of the triangular support frames 3 of a plurality of support units are fixedly connected by a transverse connecting channel steel 6.

[0031] Based on the above structure, by rotatably connecting the two triangular support frames 3, a horizontal triangular support structure can be formed by the two triangular support frames 3, so that the operation space between the plurality of support units is enlarged. When installing a single support unit, the staff can carry out installation operations through the relatively large operation space on both sides of the single support unit, thereby eliminating the drawback of the small operation space that appears when using the existing formwork support, ensuring the smooth progress of the installation operation, and thus improving the installation efficiency when using the support for single-sided formwork in the basement while ensuring a stronger support effect;

[0032] At the same time, the movable support columns 4 are arranged in a rotational connection manner, which is also beneficial to vertically tension and fix the movable support columns 4 to the channel steel back ribs 2 by connection fasteners, so as to ensure that when the two triangular support frames 3 form an included angle with each other, the movable support columns 4 and the channel steel back ribs 2 will not form an included angle, avoiding the phenomena of unstable connection and easy damage of the fasteners after connection due to force.

[0033] Further, the rotating connection assembly 8 includes a connection holding plate 801, a connection block 802, and a connection bolt 803. The connection holding plate 801 is fixed to the middle of one side of the triangular support frame 3 away from the channel steel back rib 2. The connection block 802 is fixed to the middle of the other side of the triangular support frame 3 away from the channel steel back rib 2. The connection block 802 is rotatably clamped in the connection holding plate 801, and the lower end of the connection bolt 803 movably penetrates through the connection holding plate 801 and the connection block 802;

[0034] The connecting member includes a connecting bearing 7. Both the upper and lower ends of the movable support column 4 are rotatably connected to both ends of the triangular support frame 3 through the connecting bearing 7.

[0035] Through the arrangement of the rotating connection assembly 8 and the connecting bearing 7, the two triangular support frames 3 are rotatably connected. At the same time, a single movable support column 4 and a single triangular support frame 3 are also rotatably connected. Thus, it is convenient to flexibly adjust the distance between the two movable support columns 4 and the orientation of the movable support column 4 to meet the installation requirements of multiple densities (i.e., the installation density after adjusting the installation distance between the movable support columns 4), so as to provide a stronger support effect.

[0036] Further, a support rod 5 is fixed to the inner side of the inclined side wall of the triangular support frame 3 close to the channel steel back rib 2. One end of the support rod 5 away from the triangular support frame 3 is integrally formed with a support seat 501. An arc-shaped notch is provided at the front end of the support seat 501, and the arc-shaped notch of the support seat 501 is in sliding contact with the arc-shaped side wall of the movable support column 4;

[0037] Through the arrangement of the support seat 501, the movable support column 4 can be effectively supported on the premise that the movable support column 4 can rotate to adjust its own orientation. Thus, it plays the same strengthening role as the support rod in the prior art, ensuring the overall structural strength of the support for the single-sided formwork of the basement.

[0038] Further, a plurality of compensation springs 9 are fixed between the inclined side walls of the two triangular support frames 3 of the support unit. The plurality of compensation springs 9 are evenly distributed along the extending direction of the inclined side wall of the triangular support frame 3;

[0039] Through the arrangement of the compensation springs 9, a compensation support can be established between the two triangular support frames 3, thereby avoiding low support strength between the two triangular support frames 3. At the same time, it can also make the two triangular support frames 3 have a mutual influence tension after being opened, so as to disperse the pressure exerted by the basement wall form on a single triangular support frame 3, and further provide a more powerful single-sided support effect.

[0040] Among them, a transverse channel steel mounting seat 301 is fixed on the side wall of the inclined wall of the triangular support frame 3 away from the channel steel back rib 2. The transverse channel steel mounting seat 301 is an L-shaped support block. The transverse connecting channel steel 6 is placed on the transverse channel steel mounting seat 301 and fixed to the transverse channel steel mounting seat 301 through bolts, so as to facilitate connecting multiple triangular support frames 3 to form an overall stable single-side formwork structure.

[0041] The working principle of the present utility model: During daily use, first install the steel panel 1 on one side of the basement wall formwork, and install the channel steel back rib 2 on the other side of the steel panel 1 through bolts. Then, open a single connecting unit to an appropriate angle so that the distance between the two movable support columns 4 meets the installation requirements. After that, rotate the movable support column 4 so that the connecting fastener mounting hole 401 of the movable support column 4 forms a vertical state with the channel steel back rib 2. At this time, just fix the movable support column 4 and the channel steel back rib 2 in a tensioned manner through the connecting fastener to complete the installation of a single support unit. Finally, install and fix the transverse connecting channel steel 6 between the multiple triangular support frames 3 of multiple support units through bolts to complete the installation operation of the support for the single-side formwork of the basement.

[0042] During the installation process, since the two triangular support frames 3 are rotatably connected, the two triangular support frames 3 can form a horizontal triangular support structure, thereby expanding the operation space between multiple support units. When installing a single support unit, the staff can carry out the installation operation through the relatively large operation space on both sides of the single support unit, thus eliminating the disadvantage of the relatively small operation space that appears when using the existing formwork support, ensuring the smooth progress of the installation operation, and thus improving the installation efficiency when using the support for the single-side formwork of the basement while ensuring a stronger support effect.

[0043] In addition, the movable support column 4 is arranged in a rotatable connection manner, which is also beneficial to fix the movable support column 4 and the channel steel back rib 2 in a vertical tensioned manner through the connecting fastener, so as to ensure that when the two triangular support frames 3 are at an included angle with each other, the movable support column 4 and the channel steel back rib 2 will not form an included angle, avoiding the phenomena of unstable connection and easy damage of the fastener after connection due to force.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
