[0023] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0024] The embodiment of the present application provides a cast-in-place component formwork for narrow spaces, which can solve the problems in the prior art that the formwork of components has poor compatibility and cannot be adapted to install the formwork of components in narrow spaces with different widths.

[0025] Since in the construction of narrow spaces with different widths, due to the difficulty in installing the formwork of components on both sides of the gap, the main methods currently adopted include staggered construction and formwork sandwich fillers. On the one hand, the poor compatibility means that it cannot adapt to gaps with different widths; on the other hand, the abutting force of the formwork on both sides is not enough to ensure the construction quality. Then a cast-in-place component formwork that can adjust the formwork spacing according to the gap width is implemented, and it can limit and abut the formwork on both sides when reaching the target spacing to complete positioning and high-quality construction, so as to solve some problems such as compatibility and construction quality in the current situation.

[0026] Please refer to Figures 1-4 , a cast-in-place component formwork for narrow spaces, which includes: a limiting beam 3, with panels 1 abutted at both ends thereof; a vertical moving component 4, which is connected to the limiting beam 3 and is located between the two panels 1; the vertical moving component 4 includes a vertical moving part 5; support rods 52 are hinged on both sides of the vertical moving part 5 in the length direction of the limiting beam 3, and the end of the support rod 52 far from the vertical moving part 5 is hinged to the corresponding panel 1.

[0027] With this connection structure, the vertical moving part 5 drives the panel 1 hinged to the other end of the strut 52 to move away from or close to the vertical moving part 5 by hinged rotation with the struts 52 on both sides in the length direction of the limit beam 3, so as to adjust the distance between the two panels 1 to adapt to the installation of the in-situ component formwork in gaps of different widths. Secondly, the vertical moving component 4 abuts against the two side panels 1 through the struts 52, and it can abut against and limit the vertical moving part 5, so as to fix the two side panels 1. Effectively solve the problems of distance adjustment of the in-situ component formwork and limit fixation of the two side panels.

[0028] In some preferred embodiments, stiffening ribs 2 are provided on the peripheral side of the panel 1; notch openings 31 are provided at both ends of the limit beam 3; the notch openings 31 at both ends of the limit beam 3 are clamped and abutted against the stiffening ribs 2 at the top of the panel 1. With this connection method, the load-bearing capacity of the panel 1 is improved, and the stability and stiffness of the structure are enhanced. The design of the stiffening ribs 2 and the notch openings 31 can ensure that the connection between the panel 1 and the limit beam 3 is firm and reliable. It should be noted that the abutting connection between the limit beam 3 and the stiffening ribs 2 ensures the up-and-down abutment between the limit beam 3 and the stiffening ribs 2, but fine adjustment can be made in the horizontal direction. By reasonably designing the dimensions and positions of the stiffening ribs 2 and the notch openings 31, the connection between the in-situ component formworks can be made more firm, and the safety and durability of the overall structure can be improved.

[0029] In some preferred embodiments, the width of the stiffening rib 2 is L3, and the wall thickness is L4; the depth of the notch opening 31 is L1, L1 > L3; the width of the notch opening 31 is L2, L2 = L4. The design of the notch opening 31 has certain requirements for depth and width. The depth L1 of the notch opening 31 is slightly greater than the width L3 of the stiffening rib 2, so as to ensure that the notch opening 31 can completely accommodate the stiffening rib 2 and ensure the stability of the connection. At the same time, the width L2 of the notch opening 31 is equal to the wall thickness L4 of the stiffening rib 2, so as to ensure the fit between the stiffening rib 2 and the notch opening 31 and the accuracy of the connection. The notch opening 31 designed in this way can better meet the requirements of the structure, ensure that the connection between the panel 1 and the limit beam 3 is smooth horizontally and firm and reliable longitudinally, and improve the stability of the overall structure. By reasonably designing the dimensions and positions of the notch opening 31, the dislocation or loosening phenomenon between the in-situ component formworks can be effectively prevented, and the load-bearing capacity and durability of the structure can be further enhanced.

[0030] In some preferred embodiments, a vertically downward through hole is provided at the central axis of the limit beam 3; the vertical moving assembly 4 includes a nut 41 and a limit bolt 42, and the nut 41 is fixedly arranged in the through hole; the limit bolt 42 is rotatably connected to the nut 41. The function of this design is to achieve an adjustable connection between the limit beam 3 and the vertical moving assembly 4 through the combination of the nut 41 and the limit bolt 42. Specifically, the nut 41 is fixedly arranged in the through hole at the central axis of the limit beam 3, and the limit bolt 42 is rotatably connected to the nut 41. By rotating the limit bolt 42, the vertical moving part located directly below it can be pushed downward, indirectly moving the two side panels 1 away from the vertical moving part 5. Secondly, after reaching the limited spacing, that is, when the two side panels respectively abut against the two side concrete walls 6, stop rotating the limit bolt 42 and abut against the limit vertical moving part, indirectly limiting and fixing the two side panels 1, and the formwork of the entire cast-in-place member reaches a tightened state. The advantage of this design is that the spacing adjustment of the panels and the limit fixation of the panels can be achieved through simple rotation and positioning operations, improving the installation and debugging efficiency. At the same time, the connection method between the nut 41 and the limit bolt 42 is stable and reliable, ensuring the stability of the limit.

[0031] In some preferred embodiments, the vertical moving part 5 is located directly below the limit bolt 42; the vertical moving part 5 includes a first moving part; the first moving part includes a abutting disk 51, and struts 52 are hinged on both sides of the abutting disk 51 in the length direction of the limit beam 3. In this design, the vertical moving part 5 is located directly below the limit bolt 42, so that the limit bolt 42 can push and abut against the vertical moving part 5. The abutting disk 51 is the main component of the first moving part. It is located between the two panels 1. The hinged structure of the abutting disk 51 enables it to be connected to the struts 52 and can achieve a certain degree of inclination and rotation. The vertical moving part flexibly adjusts the angle between the struts 52 and the abutting disk 51 by moving up and down to adjust the distance between it and the two panels 1, so as to adapt to the spacing requirements of different installation scenarios. Supported by the hinges on both sides, the struts 52 provide additional stability and support force, making the entire structure more solid and reliable.

[0032] In some preferred embodiments, a hinge portion 21 is provided on the stiffening rib 2 located on the side of the panel 1; one end of the strut 52 away from the first moving portion is hinged to the hinge portion 21 of the corresponding panel 1. The provision of the hinge portion 21 on the stiffening rib 2 can make the connection between the strut 52 and the panel 1 more flexible, and at the same time provide support and stability for the hinge point. One end of the strut 52 is connected to the hinge portion 21 on the stiffening rib 2 by means of a hinge. This connection method can enable the strut 52 to make a certain rotation and adjustment relative to the panel 1, which helps to adapt to different installation scenarios and angles that need to be adjusted, so as to adjust the distance between the two panels 1. By strengthening the design of the stiffening rib 2 and the hinge portion 21, the stability and load-bearing capacity of the entire structure can be increased. The hinge connection between the strut 52 and the hinge portion 21 can achieve the rotational adjustment of the panel 1 relative to the strut 52 when needed, providing more convenience for the use and maintenance of the entire structure.

[0033] In some preferred embodiments, a straight column 53 is provided at the bottom of the abutting disc 51, and a plurality of moving portions are provided on the straight column 53; the structure of each moving portion is the same as that of the first moving portion. By providing the straight column 53 at the bottom of the abutting disc 51 and installing a plurality of moving portions on the straight column 53, the stability and load-bearing capacity of the entire structure can be effectively improved. The structure of each moving portion is the same as that of the first moving portion, which can improve production efficiency and the universality of components, and reduce production costs and maintenance costs. Through this design, the stability and practicality of the structure are improved.

[0034] In some preferred embodiments, one end of the strut 52 of the moving portion away from the moving portion is hinged to the hinge portion 21 of the corresponding panel 1. This design can enable the moving portion to push or pull the two side panels 1 through a plurality of struts 52, thereby changing the distance between the two side panels, making the entire structure more stable and reliable, and increasing the stability and adjustability of the structure.

[0035] In some preferred embodiments, hinge holes 521 are provided at both ends of the strut 52. It is hinged to the abutting disc 51 through the hinge hole 521 at one end, and the hinge hole 521 at the other end is hinged to the hinge portion 21 of the panel 1. Such a design can achieve flexible connection between the strut 52, the abutting disc 51 and the panel 1, making the entire structure more stable and reliable during the movement process. Through this design, the strut 52 can rotate at the two hinge points, facilitating the adjustment of the distance and fixation. At the same time, the provision of the hinge holes 521 at both ends of the strut 52 also facilitates the installation and disassembly of the entire structure, facilitating maintenance and replacement of components.

[0036] In some preferred embodiments, a design distance is provided between the limit bolt 42 and the vertical moving part 5. This design is mainly used to control the moving range of the vertical moving part 5, avoiding the situation where the axial expansion and contraction of the limit bolt 42 cannot reach the vertical moving part. By setting the design distance between the limit bolt 42 and the vertical moving part 5, it can be ensured that the vertical moving part 5 always stays within the specified range during movement and will not exceed or be lower than the position required by the design. The limit bolt 42 is usually set at the extreme position of the moving part. When the vertical moving part 5 moves to the limit position, the limit bolt 42 will contact it, thereby restricting its further movement. Thus, the final position of the panel 1 is limited and fixed.

[0037] The beneficial effects brought by the present utility model include:

[0038] The main function is to realize the distance adjustment and fixation between the vertical moving part 5 and the panel 1 to meet the installation requirements for gaps of different widths, and at the same time maintain the stability and reliability of the structure during the adjustment process. Through the hinged connection between the support rod 52 on the vertical moving part 5 and the panel 1, the following functions and advantages can be achieved:

[0039] 1. Distance adjustment function: By adjusting the relative position between the vertical moving part 5 and the panel 1, the distance between the panels can be adjusted to meet the installation requirements for gaps of different widths. This flexible adjustment mechanism can improve the applicability and flexibility of construction.

[0040] 2. Fixing effect: The limit bolt 42 limits and holds the vertical moving part 5. The vertical moving part 5 holds the two side panels 1 against the concrete walls 6 on both sides of the installation through the support rod 52, and can hold and fix the panel 1 at the required position, ensuring that the panel 1 will not move or be displaced during the installation process, and improving the stability and reliability of the overall structure.

[0041] 3. Simplify the installation process: This connection structure design can bring a simplified installation process. By adjusting the length and position of the support rod, the distance adjustment and fixation between the panels can be achieved, reducing the complexity and cost during the construction process.
