[0025] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0026] like Figures 1-5 As shown, this utility model proposes a rapid installation and dismantling formwork system for a basement sump pit, including a bottom formwork 10, side formwork assemblies 20, internal supports 70, and corner formwork assemblies 30. The bottom formwork 10 is placed on top of the vibrated concrete bottom slab of the sump pit. The side formwork assemblies 20 are placed on top of the bottom formwork 10 to shape the four side walls of the sump pit. The internal supports 70 abut against the opposing side formwork assemblies 20, providing sufficient support to prevent the side formwork assemblies 20 from moving or deforming under the lateral pressure generated during concrete pouring. The corner formwork assemblies 30 are placed on top of the bottom formwork 10 and abut against the side formwork assemblies 20 on both sides to shape the four corners of the sump pit.

[0027] In one specific embodiment, the present invention proposes a rapid installation and dismantling formwork system for basement sump pits, used for the construction of sump pits with rectangular cross-sections. The sump pit includes a bottom surface, side walls, and corners. The side walls are perpendicular to the bottom surface, and adjacent side walls are vertically connected to form four corners. The present application uses a bottom surface formwork 10 to fix the side formwork components 20, and uses internal supports 70 to connect the side formwork components 20 into a whole. At the same time, the corner formwork components 30 are fixed to the side formwork components 20 by abutting against them, realizing a rapid and stable connection of the formwork system. During construction, the sump pit bottom slab concrete is poured first, and after being vibrated and compacted, the bottom surface formwork 10, side formwork components 20, and corner formwork components 30 are quickly installed. Subsequently, the sump pit side walls are poured. This effectively avoids the situation where the sump pit bottom slab concrete is not compacted, ensuring that the sump pit bottom slab and side walls are cast in one go, while improving construction efficiency.

[0028] Furthermore, the corner template assembly 30 includes a corner template 31, and the side template assembly 20 includes a side template 21. Both the corner template 31 and the side template 21 are set along the entire length of the height of the sump and are assembled to form a shape that matches the sump, so that the side wall of the sump has a good quality effect after molding. At the same time, the side template 21 and the corner template 31 are spliced ​​and connected, making it easier to install and disassemble.

[0029] Preferably, the joint between the side formwork 21 and the corner formwork 31 is inclined towards the corner formwork 31. That is, the side formwork 21 and the corner formwork 31 are connected by an inclined joint, which helps to prevent concrete from seeping into the inside of the formwork along the joint. It also allows the side formwork 21 to provide support for the corner formwork 31, preventing the corner formwork 31 from moving inward or tilting.

[0030] Specifically, both the corner template 31 and the side template 21 are made of multi-layer wooden templates, and their height is the height of the sump. The corner template 31 includes two vertically connected flat panels. Preferably, the corner template 31 is made of flat panels of the same specification. The length of the side template 21 and the length of the flat panels of the corner template 31 on both sides are the length of one side wall of the sump. By standardizing the processing and manufacturing of the corner template 31, it is beneficial to ensure the construction quality of the corner part of the sump and at the same time reduce the difficulty of template processing.

[0031] Preferably, the corner template 31 and the side template 21 are made by cutting and manufacturing templates that are compatible with the side wall of the sump.

[0032] The side formwork assembly 20 also includes timber 22 and steel pipes 23. The timber 22 is arranged between the steel pipes 23 and the side formwork 21. Multiple timber 22 are evenly distributed along the length of the side formwork 21 and are arranged vertically. Multiple steel pipes 23 are evenly spaced along the height of the timber 22, and their length is sufficient to connect all the timber 22 inside the same side formwork 21. An internal support 70 is provided between two oppositely arranged steel pipes 23.

[0033] Specifically, the internal support 70 includes a top plate, a threaded rod, and a sleeve. The threaded rod is threaded to both ends of the sleeve, and the top plate is connected to the other end of the threaded rod and abuts against the steel pipe 23. By rotating the sleeve, the overall length of the internal support 70 can be adjusted so that the top plate provides sufficient support to the steel pipe 23.

[0034] Preferably, the inner supports between the steel pipes 23 on opposite sides and the inner supports between the steel pipes 23 on the other two opposite sides are arranged in a crisscross pattern.

[0035] The rapid installation and dismantling formwork system for basement sump pits proposed in this application also includes a limiting component 60, which includes a first limiting member 61 and a second limiting member 62. The first limiting member 61 is disposed opposite to both ends of the side formwork 21, and the second limiting member 62 is disposed opposite to both ends of the corner formwork 31. The second limiting member 62 fits into the first limiting member 61, and the joint between the two is aligned with the joint between the side formwork 21 and the corner formwork 31.

[0036] Preferably, the first limiting member 61 and the second limiting member 62 are made of wooden beams 22 and are both set along the height direction of the sump. The length of the steel pipe 23 extends to the first limiting member 61 so that the first limiting member 61 is better fixed to the side template 21. The edge of the first limiting member 61 is aligned with the edge of the side template 21. Preferably, the first limiting member 61 has a slope, and the inclination angle of the slope is the same as the inclination angle of the joint between the side template 21 and the corner template 31. Similarly, the second limiting member 62 also has a slope with the same angle, so that the joint formed after the slope of the first limiting member 61 and the slope of the second limiting member 62 are fitted together is aligned with the joint between the side template 21 and the corner template 31. At the same time, the corner template assembly 30 abuts against the limiting assembly 60 so that the corner template 31 is spliced ​​with the side template 21 and the corner template assembly 30 is fixed to the side template assembly 20.

[0037] The aforementioned corner template assembly 30 also includes a right-angle pad 32, a connector 33, and a trapezoidal pad 34; wherein the right-angle pad 32 is attached to the outside of the corner template 31; the corner of the corner template 31 is provided with a connecting hole, the connector 33 passes through the connecting hole, one end of which is connected to the right-angle pad 32, and the other end passes through the trapezoidal pad 34 and is provided with a fastener; the small end of the trapezoidal pad 34 faces the corner, and the two inclined surfaces of the trapezoidal pad 34 respectively abut against the joint of the first limiting member 61 and the second limiting member 62.

[0038] Specifically, such as Figure 1 , Figure 3 As shown, the right-angle pad 32 is arranged along the height direction of the corner template 31, and its shape is adapted to the corner part of the corner template 31, so that it can fit against the outside of the corner part; multiple connectors 33 are arranged at intervals, and multiple reserved holes are provided from top to bottom at the corner part of the corner template 31. One end of the connector 33 is connected to the inside of the right-angle pad 32, and the other end passes through the reserved hole and through the trapezoidal pad 34. Its end is provided with a fastener. By tightening the fastener, the trapezoidal pad 34 can be moved towards the corner part, so that the two inclined surfaces of the trapezoidal pad 34 respectively clamp the joint of the first limiting member 61 and the second limiting member 62.

[0039] Specifically, the shape of the trapezoidal pad 34 is set according to the spacing of the joint between the first limiting member 61 and the second limiting member 62 at both ends. The length of its small end is less than the distance between the two joints, and the length of its large end is greater than the distance between the two joints, so that the trapezoidal pad 34 can be stuck between the two joints, making the joint between the corner template 31 and the side template 21 tightly connected, and at the same time playing a role in strengthening the support of this part.

[0040] Preferred, such as Figure 3 As shown, the side of the first limiting member 61 and the second limiting member 62 away from the side template 21 is parallel to the side template 21. The inclination angle of the two inclined surfaces of the trapezoidal pad 34 is 45 degrees. When the small end of the trapezoidal pad 34 faces the corner, its two inclined surfaces can be parallel to the sides of the first limiting member 61 and the second limiting member 62 at its two ends, respectively. By tightening the fasteners, the trapezoidal pad 34 is tightly fitted with the first limiting member 61 and the second limiting member 62, realizing the tight splicing of the corner template 31 and the side template 21. At the same time, the first limiting member 61 can provide support for the second limiting member 62 to prevent the corner template 31 from tilting or moving inward.

[0041] A reinforcing member 35 is also provided on the inner side of the corner. The two sides of the reinforcing member 35 are respectively attached to the corner template 31. The connecting member 33 passes through the reinforcing member 35 so that the reinforcing member 35 is fixed to the connecting member 33. This design improves the rigidity of the template at the corner, which is conducive to ensuring the construction quality of the corner of the sump.

[0042] Furthermore, such as Figure 4 As shown, the steel pipe 23 is fixed to the side template 21 by fastening bolts 24 and butterfly valves 25. Specifically, the side template 21 has several holes through which the fastening bolts 24 pass and through the gap between two parallel steel pipes 23. The ends of the fastening bolts 24 are provided with butterfly valves 25, which fasten the two steel pipes 23, making the connection between the steel pipes 23, the timber 22 and the side template 21 more stable.

[0043] Furthermore, such as Figure 5 As shown, the side template 21 is fixed to the bottom template 10 by angle steel 40 and connecting bolts 50. Specifically, the bottom of the side template 21 and the edge of the bottom template 10 are provided with holes. The horizontal and vertical surfaces of the angle steel 40 are provided with U-shaped grooves. The connecting bolts 50 pass through the holes and the U-shaped grooves of the angle steel 40 respectively. The horizontal surface of the angle steel 40 is fixed to the upper part of the bottom template 10 by fastening bolts 24, and the vertical surface of the angle steel 40 is fixed to the inner bottom of the side template 21, so as to realize the detachable connection between the side template 21 and the bottom template 10. Preferably, multiple angle steels 40 are provided along the length of the side template 21 to make the connection between the side template 21 and the bottom template 10 more stable.

[0044] The construction method using the aforementioned rapid installation and dismantling formwork system for basement sump pits includes the following steps:

[0045] Make corner template 31 and side template 21 according to the shape of the sump pit, and install right angle shims 32, connectors 33 and trapezoidal blocks 34 on corner template 31;

[0046] Preferably, a side wall template is first made according to the shape of the sump side wall, and the length and height of the side wall template are the same as those of the sump side wall. Then, the side wall template is cut into two flat plates and a side template 21. During the cutting, it is ensured that the cut surface is neat and can be tightly spliced. Then, the corresponding flat plates are vertically connected in pairs to form a corner template 31. Then, holes are drilled at the corner of the corner template 31, and one end of the connector 33 is welded to the inside of the right angle pad 32 so that the connector 33 passes through the reserved hole at the corner. Then, the trapezoidal pad 34 is installed on the other end of the connector 33 and initially fixed with fasteners.

[0047] Tie the bottom slab reinforcement of the sump pit, pour the bottom slab concrete, and fully vibrate the bottom slab concrete.

[0048] After the base slab concrete is vibrated and compacted, immediately install the bottom formwork 10 and place the bottom formwork 10 on the upper surface of the poured base slab concrete; fix the angle steel 40 to the preset position of the bottom formwork 10 with connecting bolts 50.

[0049] The corner template 31 is temporarily fixed on the upper part of the bottom template 10, so that the four corner templates 31 are tightly attached to the bottom template 10 and located at the preset position of the sump pit;

[0050] Install the side template 21 and fix the side template 21 to the angle steel 40 by connecting bolts 50, so that the side template 21 fits against the upper part of the bottom template 10;

[0051] Install the first limiting member 61 inside the side template 21 so that the first limiting member 61 is aligned with the edge of the side template 21; install the second limiting member 62 inside the corner template 31 so that the second limiting member 62 is aligned with the edge of the corner template 31.

[0052] Tighten the fasteners so that the trapezoidal pad 34 abuts against the joint between the first limiting member 61 and the second limiting member 62;

[0053] Install timber 22 and steel pipe 23 inside the side template 21, and install internal support 70 between two opposite steel pipes 23;

[0054] Pour concrete for the walls of the sump pit;

[0055] Once the concrete in the sump pit reaches the set strength, the internal support 70, corner formwork assembly 30, side formwork assembly 20, and bottom formwork 10 can be removed without damaging the already formed concrete.

[0056] This invention, by setting a bottom template, enables the rapid installation of side template components and corner template components after the bottom sump of the sump is poured. This effectively avoids the problem of insufficient compaction of the concrete in the bottom sump, while ensuring that the bottom sump and side walls are poured in one go, improving construction efficiency and saving time. The bottom template is used to fix the side template components, and internal supports are used to connect the side template components into a whole. At the same time, the side template components abut against the corner template components, achieving a rapid and stable connection of the template system. The overall operation is simple, and the installation and dismantling are quick, reducing the use of manual labor and machinery and lowering construction costs.
