[0044] In a specific embodiment, a basement sump quick installation and disassembly formwork system proposed by the present invention is used for the construction of a sump with a rectangular cross-section, the sump including a bottom surface, side walls and corners, the side walls are respectively perpendicular to the bottom surface, and two adjacent side walls are vertically connected to form four corners; the present application utilizes a bottom surface formwork 10 to fix the side formwork assembly 20, utilizes an internal support 70 to connect the side formwork assembly 20 as a whole, and at the same time, the corner formwork assembly 30 is fixed to the side formwork assembly 20 by abutting the side formwork assembly 20, thereby realizing a quick and stable connection of the formwork system; during construction, the sump bottom slab concrete is first poured, and after vibrating and compacting, the bottom surface formwork 10, the side formwork assembly 20 and the corner formwork assembly 30 are quickly installed, and then the sump side walls are poured, which can effectively avoid the situation where the sump bottom slab concrete is not vibrated densely, ensure that the sump bottom slab and the side walls are cast and formed in one time, and at the same time improve the construction efficiency.

[0045] Furthermore, the corner formwork assembly 30 includes a corner formwork 31, and the side formwork assembly 20 includes a side formwork 21. The corner formwork 31 and the side formwork 21 are both arranged along 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 forming; at the same time, the side formwork 21 and the corner formwork 31 are assembled and connected, which is more convenient for installation and disassembly.

[0046] Preferably, the joint between the side formwork 21 and the corner formwork 31 is inclined toward the direction close to the corner formwork 31. In other words, the side formwork 21 and the corner formwork 31 are connected by the oblique joint, which is conducive to preventing the concrete from leaking to the inside of the formwork along the joint between the two, and also enables the side formwork 21 to provide support for the corner formwork 31 to prevent the corner formwork 31 from moving or tilting inward.

[0047] Specifically, the corner template 31 and the side template 21 both use multi-layer wooden templates, and the height of the two is the height of the sump; the corner template 31 includes two vertically connected flat panels, and preferably the corner template 31 is made of flat panels of the same specifications, and the sum of the length of the side template 21 and the length of the flat panels of the corner templates 31 on both sides thereof is 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, while reducing the difficulty of template processing.

[0048] Preferably, the corner template 31 and the side template 21 are made by cutting and manufacturing a template that matches the side wall of the sump.

[0049] The side formwork assembly 20 also includes wooden beams 22 and steel pipes 23. The wooden beams 22 are arranged between the steel pipes 23 and the side formwork 21.

[0050] Specifically, the internal support 70 includes a top plate, a threaded rod and a sleeve. The threaded rod is threadedly connected to the two ends of the sleeve respectively, 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 can form sufficient supporting force on the steel pipe 23.

[0051] Preferably, the inner supports disposed between the steel tubes 23 on two opposite sides and the inner supports disposed between the steel tubes 23 on the other two opposite sides are arranged in a crisscross pattern.

[0052] The basement sump quick installation and disassembly formwork system proposed in the present application also includes a limit assembly 60, which includes a first limit member 61 and a second limit member 62. The first limit member 61 is relatively arranged at the two ends of the side formwork 21, and the second limit member 62 is relatively arranged at the two ends of the corner formwork 31; the second limit member 62 is attached to the first limit member 61, and the joint between the two is aligned with the joint between the side formwork 21 and the corner formwork 31.

[0053] Preferably, the first limit member 61 and the second limit member 62 are made of wooden beams 22 and are both arranged along the height direction of the sump. The length of the steel pipe 23 extends to the first limit member 61, so that the first limit member 61 can be better fixed to the side template 21; the edge of the first limit member 61 is aligned with the edge of the side template 21. Preferably, the first limit 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 limit member 62 also has a slope at the same angle, so that the joint formed by the slope of the first limit member 61 and the slope of the second limit member 62 are aligned with the joint between the side template 21 and the corner template 31; at the same time, the corner template assembly 30 presses against the limit 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.

[0054] The above-mentioned corner template assembly 30 also includes a right-angle gasket 32, a connecting piece 33 and a trapezoidal gasket block 34; wherein the right-angle gasket 32 ​​is attached to the outer side of the corner template 31; a connecting hole is provided at the corner portion of the corner template 31, and the connecting piece 33 passes through the connecting hole, one end of which is connected to the right-angle gasket 32, and the other end passes through the trapezoidal gasket block 34 and is provided with a fastener; the small end of the trapezoidal gasket block 34 faces the corner portion, and the two inclined surfaces of the trapezoidal gasket block 34 respectively press against the joint portion of the first limit member 61 and the second limit member 62.

By screwing the fastener, the trapezoidal pad 34 can be moved toward the corner part, and finally the two inclined surfaces of the trapezoidal pad 34 are respectively clamped to the joint parts of the first limit member 61 and the second limit member 62.

[0056] Specifically, the shape of the trapezoidal pad 34 is set according to the spacing of the joints between the first limit piece 61 and the second limit piece 62 at its two ends. The length of its small end is smaller than the distance between the two joints, and the length of its large end is larger than the distance between the two joints, so that the trapezoidal pad 34 can be stuck between the two joints, so that the joints of the corner template 31 and the side template 21 are tightly connected, and at the same time, it plays a role in strengthening support for this part.

[0057] Preferably, Figure 3 As shown, a side of the first limit member 61 and the second limit member 62 away from the side template 21 is parallel to the side template 21, and 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 is toward the corner, its two inclined surfaces can be respectively parallel to the sides of the first limit member 61 and the second limit member 62 at its two ends. By screwing the fasteners, the trapezoidal pad 34 is tightly fitted with the first limit member 61 and the second limit member 62, so that the corner template 31 and the side template 21 are tightly spliced. At the same time, the first limit member 61 can provide support for the second limit member 62 to prevent the corner template 31 from tilting or moving inward.

[0058] A reinforcement member 35 is also provided on the inner side of the corner, and the two side surfaces of the reinforcement member 35 are respectively attached to the corner formwork 31, and the connecting member 33 passes through the reinforcement member 35 to fix the reinforcement member 35 to the connecting member 33; this design improves the rigidity of the formwork at the corner, which is beneficial to ensure the construction quality of the corner of the sump.

[0059] Furthermore, if Figure 4 As shown, the steel pipe 23 is fixed to the side formwork 21 by fastening bolts 24 and butterfly valves 25. Specifically, the side formwork 21 is provided with a plurality of holes, through which the fastening bolts 24 pass, and through the gap between two steel pipes 23 arranged side by side, and a butterfly valve 25 is provided at the end thereof, which fastens the two steel pipes 23, so that the connection between the steel pipe 23, the wooden beam 22 and the side formwork 21 is more stable.

[0060] Furthermore, if Figure 5 As shown, the side formwork 21 is fixed to the bottom formwork 10 by angle steel 40 and connecting bolts 50. Specifically, holes are provided at the bottom of the side formwork 21 and the edge of the bottom formwork 10, and U-shaped grooves are provided on the horizontal and vertical surfaces of the angle steel 40. The connecting bolts 50 pass through the holes and the U-shaped grooves of the angle steel 40 respectively, and the horizontal surface of the angle steel 40 is fixed to the upper part of the bottom formwork 10 by tightening bolts 24, and the vertical surface of the angle steel 40 is fixed to the inner bottom of the side formwork 21, so as to realize the detachable connection between the side formwork 21 and the bottom formwork 10; preferably, a plurality of angle steels 40 are provided along the length direction of the side formwork 21, so that the connection between the side formwork 21 and the bottom formwork 10 is more stable.
