[0031] This embodiment provides a rigid landfill construction template assembly, such as Figure 1-Figure 4 As shown, it includes a plurality of templates 1, and a mold-collecting mechanism 2 is arranged between adjacent templates. In this embodiment, four templates 1 are arranged, and two adjacent templates 1 are arranged vertically. The four templates 1 enclose a rectangular space. The arrangement of the template 1 and the mold-collecting mechanism 2 can adopt the existing technology, such as the template and the mold-collecting mechanism disclosed in patent CN214575646U. Specifically, the mold-collecting mechanism includes a corner column 2-1. Compared with the technical solution disclosed in patent CN214575646U, the cross-section of the corner column 2-1 in this embodiment is an isosceles trapezoid, and a shrinking mechanism is installed on the side where the long bottom side is located. The shrinking mechanism is connected to two adjacent templates 1, and is used to realize the inward contraction or outward expansion movement of the two adjacent templates.

[0032] like Figure 5 As shown, the retraction mechanism includes a rotating shaft 2-2, both ends of which are rotatably connected to the bearing seat, the bearing seat is fixed on the corner column 2-1, and two or more bidirectional screw segments are arranged on the rotating shaft 2-2, the bidirectional screw segment has a first thread segment and a second thread segment with opposite rotation directions, the first thread segment is slidably connected to the first slider 2-3, the second thread segment is slidably connected to the second slider 2-4, the first slider 2-3 is slidably connected to the corner column 2-1, and the second slider 2-4 is slidably connected to the corner column 2-1.

[0033] By rotating the rotating shaft 2-2, the first slider 2-3 and the second slider 2-4 can move toward or away from each other synchronously.

[0034] Both sides of the first slider 2-3 are hinged to one end of the first connecting rod 2-5 and the second connecting rod 2-6 respectively, the other end of the first connecting rod 2-5 is hinged to the first sliding member 2-7, the other end of the second connecting rod 2-6 is hinged to the second sliding member 2-8, the first sliding member 2-7 and the second sliding member 2-8 are slidably connected to the side surfaces corresponding to the long bottom sides of the corner column 2-1, the first sliding member 2-7 is fixedly connected to one of the two adjacent templates 1, and the second sliding member 2-8 is fixedly connected to the other template 1.

[0035] Correspondingly, both sides of the second slider 2-4 are hinged to one end of the third connecting rod 2-9 and the fourth connecting rod 2-10 respectively, the other end of the third connecting rod 2-9 is hinged to the first sliding member 2-7, and the other end of the fourth connecting rod 2-10 is hinged to the second sliding member 2-8.

[0036] By rotating the rotating shaft, the first slider 2-3 and the second slider 2-4 can move toward or away from each other synchronously, thereby making the multiple templates 1 approach or move away from each other.

[0037] The above technology can adopt the technology disclosed in patent CN214575646U, and the only difference is the cross-sectional shape of the corner column. The specific technical details are not described in detail here.

[0038] An oblique brace 3 is provided between the inner side surfaces of two adjacent templates, and the oblique brace 3 is detachably connected to the template 1 by bolts. By providing the oblique brace, the structural strength of the entire construction template assembly is increased.

[0039] Specifically, the end of the diagonal brace 3 is rotatably connected to a connecting plate, and the connecting plate is detachably fixedly connected to the template 1 by bolts.

[0040] The construction template assembly of this embodiment is provided with four templates 1, two of which are arranged opposite to each other, and the other two are arranged opposite to each other. The two templates 1 arranged opposite to each other in this embodiment refer to two templates 1 parallel to each other in the construction template assembly.

[0041] Among the two relatively arranged templates 1, one of the templates is provided with a first through hole 1-1 for installing a three-stage water-stop screw, and the number of the first through holes 1-1 can be set according to actual needs. The other template 1 is provided with second through holes 1-2 corresponding to the first through holes 1-1, and the number of the second through holes 1-2 is the same as that of the first through holes 1-1, and the corresponding first through holes 1-1 and second through holes 1-2 are coaxially arranged.

[0042] The diameter of the first through hole 1-1 matches the diameter of the screw portion of the three-stage water-stop screw, allowing the screw portion to pass through but not allowing the cone and the water-stop plate to pass through. In this embodiment, the diameter of the first through hole 1-1 is 18mm-22mm, preferably 20mm.

[0043] The diameter of the second through hole 1-2 is larger than the larger value between the maximum diameter of the conical body of the three-stage water-stop screw and the diameter of the water-stop plate, so that the entire three-stage water-stop screw can pass through the second through hole. In this embodiment, the diameter of the second through hole is 33mm-37mm, preferably 35mm.

[0044] With this arrangement, since the three-section water-stop screw can pass through the second through hole 1-2 as a whole, during construction, multiple pre-assembled rigid landfill construction assemblies can be directly hoisted as a whole into the corresponding area of ​​the rigid landfill, and then the three-section water-stop screw enters from the second through hole 1-2, and then passes through the template 1 close to each other between two adjacent template assemblies, and then the three-section water-stop screw is fastened between the two adjacent template assemblies. Therefore, during construction of the template assembly, there is no need to assemble it at the construction site, and it can be directly pre-assembled and hoisted into the corresponding position. The construction is convenient and quick, which improves the construction efficiency and avoids the safety hazards of on-site assembly.

[0045] Example 2

[0046] This embodiment provides a rigid landfill construction template system, such as Figure 6 As shown, it includes multiple rigid landfill construction template assemblies described in Example 1, and each rigid landfill construction template assembly corresponds to a landfill grid of a rigid landfill.

[0047] In the adjacent rigid landfill construction template assembly, a three-section water-stop screw 4 is arranged between two templates close to each other.

[0048] The three-stage waterstop screw can adopt the existing technology, including a waterstop rod segment 4-1, a waterstop plate 4-2 is arranged on the waterstop rod segment 4-1, one end of the waterstop rod segment 4-1 is threadedly connected to the first screw segment 4-3, and a first cone 4-4 is arranged on the periphery of the connection position between the first screw segment 4-3 and the waterstop rod segment 4-1, and the end of the first cone 4-4 with a larger area is arranged toward the first screw segment 4-3, the other end of the waterstop rod segment 4-1 is threadedly connected to the second screw segment 4-5, and a second cone 4-6 is arranged on the periphery of the connection position between the second screw segment 4-5 and the waterstop rod segment 4-1, and the end of the second cone 4-6 with a larger area is arranged toward the second screw segment.

[0049] The water stop section and the two cones are used to be buried inside the poured concrete wall to play a water stop role.

[0050] The diameter of the first through hole 1-1 matches the diameter of the first screw segment 4-3, and the diameter of the second through hole 1-2 is greater than the larger value between the maximum diameter of the cone and the diameter of the water stop plate 4-2.

[0051] In the two templates 1 close to each other of two adjacent construction template assemblies, the first screw segment 4-3 passes through the first through hole 1-1 of one of the templates 1, the first cone 4-4 fits with the outer side surface of the template 1, and the second screw segment 4-5 passes through the second through hole 1-2 of the other template 1. Since the diameter of the second through hole 1-2 is larger than the diameter of the second screw segment 4-5, a water-stop seal 5 is arranged between the second screw segment 4-5 and the hole surface of the second through hole 1-2.

[0052] The water-stop seal 5 is made of plastic or steel. Figure 7 As shown, it includes a sleeve portion 5-1, which is sleeved on the outer periphery of the second screw segment, and the two ends of the sleeve portion 5-1 are provided with a first fitting portion 5-2 and a second fitting portion 5-3, and the first fitting portion 5-2 and the second fitting portion 5-3 both adopt a disc-shaped structure, and the first fitting portion 5-2 is fitted with the outer side surface of the template 1, and the first fitting portion 5-2 is provided with a sealing ring 5-4, which extends between the second screw segment 4-5 and the second through hole 1-2, and the outer side surface of the sealing ring 5-4 is sealed and fitted with the hole surface of the second through hole 1-2, thereby playing a role of water-stopping seal.

[0053] In this embodiment, a back rib 6 is provided on the outer side of the two templates, wherein the first screw segment 4-3 passes through the template 1 and the back rib 6 and is threadedly connected with a fastener. The fastener is a mountain-shaped clip and a nut located on the outer side of the mountain-shaped clip. By rotating the nut, the mountain-shaped clip presses the back rib, thereby pressing the back rib against the outer side of the template.

[0054] A back rib 6 is arranged on the outer side of the water-stop seal 5, and the back rib 6 is fitted with the second fitting portion 5-3. The second screw portion 4-5 passes through the template 1, the water-stop seal 5 and the back rib 6 and is threadedly connected with a fastener. The fastener adopts a mountain-shaped clip and a nut located on the outer side of the mountain-shaped clip. The nut is rotated to press the mountain-shaped clip against the back rib 6, thereby pressing the back rib 6 against the outer side of the second fitting portion 5-2.

[0055] Furthermore, since a reinforcing rib is provided on the inner side surface of the template 1, a notch is provided in the first fitting portion 5-2 to leave space for providing the reinforcing rib.

[0056] The template system further includes a plurality of lifting mechanisms 7 . A plurality of lifting mechanisms 7 are disposed below each template assembly, and the lifting mechanisms 7 support the template assembly.

[0057] In this embodiment, a lifting mechanism 7 is provided at the bottom surface of the corner column 2 - 1 of the template assembly and the middle position of the bottom surface of each template 1 , and the template assembly can be supported and leveled through the lifting mechanism 7 .

[0058] Preferably, the lifting mechanism 7 adopts an existing scissor-type lifting mechanism, and its specific structure is not described in detail here.

[0059] like Figure 8 As shown, the construction method of the formwork system of this embodiment includes the following steps:

[0060] Step 1: Before construction, divide the rigid landfill into several partitions according to actual needs to form multiple landfill grids to facilitate construction operations and save template consumables.

[0061] Step 2: Before the formwork is installed, a 0.4-meter-high concrete wall 8 is poured along the edge of the landfill grid to facilitate the installation and fixation of the formwork assembly.

[0062] Step 3: Install the lifting mechanism 7 at the four corners and the center of the four sides of the landfill grid.

[0063] Step 4: After cleaning the template 1 of the pre-assembled rigid landfill construction template assembly, evenly apply the release agent on the inner side with a roller to prevent the release agent from flowing. If there is strong wind, rain or fog, the release agent needs to be reapplied.

[0064] Step 5: Use a wrench to rotate the four shafts 2-2 of the rigid landfill construction template so that the four templates 1 move inward until they are contracted to the minimum, and then use a tower crane to lift the multiple template assemblies to the lifting mechanism 7 of the corresponding landfill grid, and then rotate the shaft 2-2 to move the template 1 outward until the outer side surface of the template is flush with the side surface where the waist of the corner column 2-1 is located.

[0065] Step 6: Use a steel ruler and plumb bob to check the verticality and diagonal dimensions of the template, adjust the lifting mechanism 7 so that the template assembly meets the horizontality requirements, and then install diagonal braces between adjacent templates.

[0066] Step 7: Install the three-section water-stop screw 4 between two adjacent template assemblies. Specifically, Figure 6 As shown, in two templates 1 close to each other of two adjacent template assemblies, the three-stage water-stop screw 4 is passed through the second through hole 1-2 of one template 1, so that the first screw segment 4-3 of the three-stage water-stop screw 4 passes through the first through hole 1-1 of another template 1 and then a back rib 6 is set on the outer side of the template 1 where the first through hole 1-1 is set, the first screw segment 4-4 passes through the back rib 6, and then a mountain-shaped clip and a nut are put on the first screw 4-3, the nut and the mountain-shaped clip are turned to press the back rib 6 against the outer side of the template 1, a sealing water-stop component 5 is inserted between the second through hole 1-2 and the second screw segment, and then the back rib 6 passed by the second screw segment 4-5 is placed, and then a mountain-shaped clip and a nut are put on the second screw segment 4-5, the nut is turned to press the back rib 6 against the second fitting portion 5-3 of the sealing water-stop component 5.

[0067] Using the same method, multiple back ribs 6 and three-stage water-stopping screws 4 are installed in sequence until all the back ribs 6 and three-stage water-stopping screws 4 are installed.

[0068] Step 8: pour concrete between two adjacent formwork assemblies to form a concrete wall, and the water-stop section 4 - 1 of the three-section water-stop screw 4 is buried inside the concrete wall.

[0069] When pouring concrete, the method of pouring in layers and intervals is adopted.

[0070] By using the formwork system and method of this embodiment, the pre-assembled formwork assembly is directly hoisted into the corresponding position, and then the back ribs and three-stage water-stop screws are installed. The construction is convenient and fast, the construction efficiency is improved, and the safety hazards of on-site assembly are avoided.

[0071] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
