Description

Technical Field

[0001] The present invention relates to the field of construction technology, and particularly to a mold, a production method and a product for integrally forming a thin-walled concrete toilet structure. Background Art

[0002] The common method for forming a thin-walled concrete toilet structure is to use wall panels and a chassis produced by flat molds and connect them by mortise and tenon joints. The flat mold production process first produces the wall panel and chassis components, and then assembles the wall panel and chassis structures. Since the wall panel and chassis components are produced separately, the complexity of the mold for a single component is relatively low. The molds for both the chassis and the wall panels are composed of a core mold and a side mold. For example, an invention patent with the application publication number CN118498525A discloses an assembled integral toilet structure, including a chassis and an assembled wall panel connected to the chassis. The chassis is a square shell with a hollow interior composed of enclosing plates. A side drainage pipe is provided on one of the enclosing plates. A floor drain communicating with the side drainage pipe is arranged near the side drainage position. The bottom surface of the chassis slopes towards the floor drain through line sloping. The side drainage pipe is connected to the main vertical pipe through a U-shaped anti-water pipe. Both the toilet and the washing machine use the wall drainage mode, and the pipes of the toilet and the washing machine are also connected to the main vertical pipe. It installs the side drainage pipe on the enclosing plate and uses the side drainage method to connect to the main vertical pipe, which is more convenient to connect to the main vertical pipe and has the effect of optimizing the drainage performance of the assembled integral toilet. However, the flat mold process needs to consider the assembly of the chassis and wall panel components. When designing the mold, it is necessary to consider the accuracy of many assembly joints between the wall panels and between the wall panel and the chassis component to avoid conflicts between the wall panel and the chassis during assembly. Therefore, although the structure of a single mold is simple, for the entire toilet structure, there are too many nodes to be controlled, and it is easy to occur that the assembly cannot be completed or the nodes are damaged, resulting in a high cost of component processing. At the same time, structural glue needs to be injected into the assembly joints between the chassis and the wall panel and between the wall panels. The cost of injecting glue is relatively high. For a single toilet, 1 chassis mold and 4 wall panel molds are required, and the floor area occupied by the molds is relatively large. In view of the above pain points, it is urgent to develop a new vertical mold production process to eliminate the glue injection process for the assembly joints between the wall panels and between the wall panel and the chassis, and improve the overall prefabrication rate of the thin-walled concrete toilet structure.

A bottom grouting port is arranged on the inner bottom middle plate, and an observation port is arranged on the outer vertical template. The thin-walled concrete toilet structure is formed by grouting from bottom to top through the bottom grouting port.

[0005] Preferably, a chute is arranged on the cross-shaped sliding support. Reinforcing brackets are fixedly installed on the outside of the outer vertical template and the outer special template, and pulleys are installed at the bottom of the reinforcing brackets.

[0012] Preferably, an operation platform is arranged on the outer side of the outer formwork, and a staircase is arranged on one side of the operation platform.

[0013] A production method of a mold for integral forming of a thin-walled concrete toilet structure, the production method includes the following steps, Step 1, foundation preparation, level the surface of the installation area where the mold is located. After leveling, the deviation of the surface flatness is not greater than 1 mm. Then hoist the cross-shaped sliding support onto the installation area and fixedly install it through expansion bolts; Step 2, mold assembly, fixedly install the outer bottom formwork at the top center position of the cross-shaped sliding support; synchronously assemble the inner mold, fixedly install the four inner vertical formworks on the top of the inner bottom formwork, install the positioning and reinforcement steel beams on the top of the inner vertical formworks, then install adjustable support members in the inner cavity of the inner mold to internally support the inner mold; install nylon blocks on the outer bottom of the inner mold; install the door formwork and multiple cavity molds on the outer side of the inner mold. After installation, use a hoisting device to hoist the inner mold as a whole above the outer bottom formwork through the positioning and reinforcement steel beams; slidably install the outer vertical formwork and the outer special formwork on the cross-shaped sliding support, slide the outer vertical formwork and the outer special formwork to the edge of the outer bottom formwork and fix them to complete the installation of the outer mold; then fixedly connect the positioning and reinforcement steel beams to the top of the outer mold; Step 3, pouring and forming, grout the pouring cavity through the bottom grouting hole. When grouting, observe the grouting situation through the wall plate observation port and the top opening. After grouting is completed, a thin-walled concrete toilet structure is formed; Step 4, mold removal, after the thin-walled concrete toilet structure reaches the design strength, remove the mold; first remove the top connection bolts of the positioning and reinforcement steel beams and the outer mold, and disassemble the adjustable support members; then simultaneously remove the inner mold, the outer mold and the door formwork, and then slide the outer vertical formwork and the outer special formwork outwards; disassemble the inner bottom formwork and the cavity molds, and transfer the thin-walled concrete toilet structure to the designated position; clean and maintain the removed mold.

[0014] A product formed by a production method, the product being a thin-walled concrete toilet structure. The thin-walled concrete toilet structure includes a chassis, four wall panels integrally provided on the circumference of the chassis, vertical ribs integrally provided on the wall panels, horizontal ribs integrally provided on the wall panels, a drainage ditch provided on the chassis, a water outlet provided in the drainage ditch, and a chassis upstand provided on the chassis. One end of the water outlet passes through the wall panel and communicates with the outside.

[0015] In the present invention, the side of the outer mold is assembled by three outer vertical templates and one outer special template. The sizes of the three outer vertical templates are relatively large, which can adapt to the mold assembly of toilets with different sizes. When the size changes, only the outer special template and the outer bottom template need to be replaced, and the three outer vertical templates only need to adjust their positions, reducing the production cost and having strong versatility. The outer vertical templates and the outer special template are slidably installed on the cross-shaped sliding bracket, which is convenient for the operations of form removal and form closing.

[0016] The outer mold adopts the form of "four whole pieces". The main stress panel of the outer vertical template is made of steel plate, and the back is surrounded by a lattice shape by a number of vertical and horizontal steel plate stiffeners. After the outer vertical template on the opposite side of the outer special template is removed, it can be completely removed to meet the requirement of horizontally lifting out from this side after the finished product is demolded, greatly reducing the requirement of vertically lifting the finished product above the mold and then horizontally lifting it out, which occupies a large amount of the hoisting height.

[0017] The inner bottom template provided is composed of an inner bottom middle plate and a plurality of inner bottom edge plates installed on the outer circumference of the inner bottom middle plate, which minimizes the influence on the cracking of the chassis of the thin-walled concrete toilet during the form removal process. Adjacent two inner bottom edge plates are connected by an inner bottom inclined plate, which not only ensures the structural strength but also reduces the disturbance to the chassis of the thin-walled concrete toilet during removal.

[0018] The door template provided can integrally pour and form the toilet door opening, avoiding the subsequent operation of cutting the door opening. The cavity mold provided can integrally form the horizontal ribs and vertical ribs, increasing the structural strength. The nylon blocks provided can form the drainage ditch and the chassis upstand after subsequent removal, avoiding subsequent secondary construction. The door template is open, which is convenient for the operators to enter the inner cavity of the inner mold from the outside and also convenient for the operators to enter and exit to observe the grouting situation. The door template is composed of four door corner molds and vertical connection templates or horizontal connection templates fixedly installed between adjacent two door corner molds, which is convenient for disassembly and assembly and is convenient for adjusting the size.

[0019] The bottom grouting port provided is located on the inner bottom middle plate, and the grouting method from bottom to top is adopted to avoid the phenomena of incomplete gas discharge and uneven pouring caused by the traditional grouting from top to bottom, ensuring the uniformity of the overall structure pouring. During grouting, the grouting situation on different sides is observed through the observation port, which is convenient for the construction personnel to more comprehensively understand the pouring situation.

[0020] The set positioning and reinforcement steel beams can, on the one hand, strengthen the overall structural strength after the installation of the inner formwork and the outer formwork, and on the other hand, limit and fix the relative positions between the inner formwork and the outer formwork, ensure the consistency of the thickness of each side wall, and also facilitate the overall hoisting of the inner formwork, serving multiple purposes with one device. The set adjustable support members can support different vertical positions of the inner formwork to avoid formwork bulging.

[0021] The set three-sided operation platform can facilitate the grouting operation of the operators and the assembly and disassembly operations of the mold, and also facilitate the operators to observe the grouting situation from the top.

[0022] This method can integrally form a thin-walled concrete toilet structure with reinforcing ribs, eliminating the assembly process between the chassis and the wall panels, saving the cost of injecting glue at the assembly joints, significantly reducing the number of joints to be controlled, reducing the wall panel thickness to 1 cm, reducing the use of concrete materials, reducing the overall weight, and avoiding the disadvantages of high cost and large production floor area of concrete toilets produced by the mortise and tenon assembly method; adopting integral pouring and molding solves the problem that the tensile and shear weak areas of the connection joints of the mortise and tenon connection structure require high concrete strength for the chassis and wall panel structures, and at the same time, the strength of the thin-walled concrete toilet structure can be appropriately reduced, and the civilized construction of the production plant area will be greatly improved, making it more suitable for the advantages of large-scale production on the assembly line.

[0024] The present invention will be further described below with reference to the accompanying drawings: As Figures 1 to 19A mold for integral forming of a thin-walled concrete toilet structure as shown, including an outer mold 1. The outer mold 1 includes an outer bottom formwork 10, three outer vertical formworks 11 vertically arranged on the outside of the outer bottom formwork 10 in sequence, and an outer special formwork 12. The length of the outer special formwork 12 is the same as the length of the corresponding side of the outer bottom formwork 10; the length of the outer vertical formwork 11 is greater than the length of the corresponding side of the outer bottom formwork 10. When it is necessary to adjust the size of the outer mold 1, only the outer bottom formwork 10 and the outer special formwork 12 with corresponding sizes need to be replaced, and the three outer vertical formworks 11 are universal. Sealing members are arranged at the connecting positions between the outer bottom formwork 10, the outer special formwork 12 and the outer vertical formworks 11 to seal the joints.

[0025] Specifically, the outer vertical formwork 11 is composed of a steel plate and stiffening ribs arranged vertically and horizontally and fixedly installed on the back of the steel plate. Bolt holes adjacent to the outer bottom formwork 10 are arranged at the bottom of the steel plate, and a plurality of bolt holes are also arranged on the stiffening ribs arranged circumferentially on the steel plate. A plurality of triangular stiffening ribs are fixedly arranged between the top stiffening rib and the steel plate, and lifting lugs are fixedly installed above the top stiffening rib.

[0026] The outer bottom formwork 10 is composed of a steel plate and channel steel or I-beam fixedly installed on the back of the steel plate. Connecting plates are fixedly arranged circumferentially at the bottom of the steel plate, and bolt holes are arranged on the connecting plates, which are adjacent to the outer vertical formwork 11 through high-strength bolts.

[0027] The outer special formwork 12 is composed of a steel plate and stiffening ribs arranged vertically and horizontally and fixedly installed on the back of the steel plate. Bolt holes adjacent to the outer bottom formwork 10 are arranged at the bottom of the steel plate, and a plurality of bolt holes are also arranged on the stiffening ribs arranged circumferentially on the steel plate. A plurality of triangular stiffening ribs are fixedly arranged between the top stiffening rib and the steel plate, and lifting lugs are fixedly installed above the top stiffening rib.

[0028] The outer mold 1 is installed on a cross-shaped sliding support 3. Specifically, the outer bottom formwork 10 is fixedly installed on the cross-shaped sliding support 3 by welding. A plurality of sliding grooves 30 are arranged on the cross-shaped sliding support 3. Reinforcement brackets 31 are fixedly installed on the outside of the outer vertical formwork 11 and the outer special formwork 12, and pulleys 32 are installed at the bottom of the reinforcement brackets 31. The pulleys 32 are slidably installed in the sliding grooves 30. A set of pulleys 32 are installed on both sides of the reinforcement bracket 31 respectively, so that the outer vertical formwork 11 or the outer special formwork 12 can slide stably. The cross-shaped sliding support 3 includes a steel frame arranged in a cross shape, a reinforcement scissors support frame fixedly arranged on the steel frame, and a plurality of embedded plates arranged on the steel frame. The cross-shaped sliding support 3 is fixedly installed through the embedded plates.

[0029] An operation platform 13 is arranged on the outer side of the outer mold 1 through fasteners or welding. Specifically, an operation platform 13 is arranged on each of the outer vertical molds 11, and a staircase 14 is arranged on one side of the operation platform 13 arranged opposite to the outer special mold 12. Workers can climb onto the operation platform 13 through the staircase 14 to carry out operations.

[0030] An inner mold 2 is installed inside the outer mold 1, and a casting cavity with an open top is formed between the outer mold 1 and the inner mold 2. Concrete is cast in the casting cavity to form a wall concrete toilet structure. As Figure 2 shown, the shaded area between the outer mold 1 and the inner mold 2 is the forming range of the thin-wall concrete toilet structure. In Figure 3 , the arrow direction is the demolding direction of the finished thin-wall concrete toilet structure.

[0031] The inner mold 2 includes an inner bottom template 20 and four inner vertical templates 21 fixedly installed on the top of the inner bottom template 20 through high-strength bolts. Sealing members are arranged at the joints between the inner bottom template 20 and the inner vertical templates 21 and between adjacent two inner vertical templates 21 to seal the joints. The inner bottom template 20 includes an inner bottom middle plate 200 and multiple inner bottom side plates 201 fixedly installed on the outer circumference of the inner bottom middle plate 200. Specifically, six inner bottom side plates 200 are arranged, and adjacent two inner bottom side plates 200 are connected by inner bottom inclined plates. This increases the connection surface area and can also reduce the disturbance to the thin-wall concrete toilet chassis during demolition, reducing the impact on the cracking of the thin-wall concrete toilet chassis during the formwork removal process.

[0032] The inner vertical template 21 includes inner corner molds 210 arranged at the four corners of the rectangle and inner connection templates 211 fixedly installed between adjacent two inner corner molds 210. Connection inclined plates 212 are arranged at the connecting parts between the inner connection templates 211 and the inner corner molds 210. Since the wall thickness of the thin-wall toilet is relatively thin, by adopting the connection method of the connection inclined plates 212, the impact on the cracking of the thin-wall concrete toilet wall during formwork removal can be reduced. When using the connection inclined plates 212, the frictional stress during formwork removal is greatly reduced compared to using straight plate connections. When removing the formwork, first remove the inner connection templates 211 and then the inner corner molds 210. Demolishing the formwork in this order will minimize the disturbance impact of the connection frictional stress between adjacent two inner vertical templates 21 on the thin-wall.

[0033] Nylon blocks 15 are installed on the outer side of the inner bottom side plates 201. The width of the nylon blocks 15 is smaller than the thickness of the inner bottom template 20. After the nylon blocks 15 are removed later, drainage ditches or decorative surface layer installation platforms can be formed, avoiding subsequent secondary construction.

[0034] Install multiple cavity molds 7 on the inner vertical formwork 21. The gaps between adjacent cavity molds form transverse ribs and vertical ribs, which can increase the structural strength of the wall panel. Reserve a laying space for internal pipelines inside the cavity formed by the cavity mold 7. The cavity mold 7 is made of plastic thin shell products and is connected to the inner vertical formwork 21 with bolts, which is convenient for removal.

[0035] On the outer special formwork 12 and the inner mold 2, there are door openings corresponding to each other in position. At the door opening, a door formwork 4 is detachably installed with bolts. The door formwork 4 has a hollow open structure. Through the door opening and the door formwork 4, it is possible to enter the inner cavity of the inner mold 2, which is convenient for operators to enter the inner cavity of the inner mold 2 from the outside for operation. The fixedly installed door formwork 4 can integrally form a toilet door opening, avoiding subsequent cutting of the door opening operation.

[0036] The door formwork 4 includes door corner molds 40 arranged at the four corners of a rectangle and vertical connecting templates 41 or horizontal connecting templates 42 fixedly installed between adjacent two door corner molds 40; at the ends of the vertical connecting templates 41 and the horizontal connecting templates 42, wedge-shaped connecting parts 43 are provided, and at the end of the door corner mold 40, a connecting plate 44 is provided. The connecting plate 44 and the corresponding wedge-shaped connecting part 43 are detachably connected with bolts, which is convenient for disassembly and assembly. The door corner mold 40 is inclinedly connected to the vertical connecting template 41 or the horizontal connecting template 42, avoiding disturbing the wall panel during form removal and reducing the risk of damaging the wall panel.

[0037] Set a bottom grouting port 8 on the inner bottom middle plate 200 and an observation port 9 on the outer vertical formwork 11; use grouting equipment to grout from the bottom up through the bottom grouting port 8 to form a thin-walled concrete toilet structure. Adopt the grouting method from the bottom up to avoid the phenomena of incomplete gas discharge and uneven pouring caused by the traditional grouting method from the top down, and ensure the uniformity of the overall structure pouring. During grouting, observe the grouting conditions on different sides through the observation port 9, which is convenient for construction personnel to understand the pouring situation more comprehensively.

[0038] At the top of the outer mold 1 and the inner mold 2, a positioning and reinforcing steel beam 5 is detachably installed with bolts. The positioning and reinforcing steel beam 5 includes two first steel beams 50 arranged in parallel at intervals and two second steel beams 51 arranged perpendicular to the first steel beams 50. At the bottom ends of the first steel beams 50 and the second steel beams 51, connecting pieces 52 are fixedly installed, and the connecting pieces 52 are connected to the tops of the outer mold 1 and the inner mold 2 with bolts. On the one hand, the positioning and reinforcing steel beam 5 can strengthen the overall structural strength after the inner mold 2 and the outer mold 1 are installed, limit and fix the relative positions between the inner mold 2 and the outer mold 1, and ensure the consistency of the thickness of the four wall panels. On the other hand, it can also facilitate the overall hoisting of the inner mold 2.

[0039] Inside the inner mold 2, multiple adjustable support members 6 are installed. The inner mold 2 is supported at different vertical positions by the adjustable support members 6 to prevent mold swelling. The adjustable support member 6 includes a threaded sleeve 60, two adjusting screws 61 threadedly installed at both ends of the threaded sleeve 60, and a support seat 62 installed at the end of the adjusting screw 61. The support seat 62 is fixedly installed inside the inner mold 2 by bolts or welding, and the thread directions at both ends of the threaded sleeve 60 are opposite. When adjusting, the threaded sleeve 60 is rotated to make the two adjusting screws 61 extend or contract synchronously. Nuts are installed on the adjusting screws 61. After the reinforcement operation is achieved by adjusting the threaded sleeve 60, the threaded sleeve 60 and the adjusting screws 61 are fixed by the nuts to ensure the stability of the support reinforcement.

[0040] Such as Figures 1 to 23 shown in the production method of a mold for integral forming of a thin-walled concrete toilet structure. This production method includes the following steps. Step 1, foundation preparation. The ground surface of the installation area where the mold is located is leveled. After leveling, the deviation of the ground surface flatness is not greater than 1 mm. Then, the cross-shaped sliding support 3 is hoisted onto the installation area and fixedly installed by expansion bolts.

[0041] Step 2, mold assembly. The outer bottom template 10 is hoisted to the top center position of the cross-shaped sliding support 3. The position of the outer bottom template 10 is adjusted by measuring instruments to ensure that the outer bottom template 10 is located at the top center position of the cross-shaped sliding support 3. After adjustment, it is fixed by welding.

[0042] The inner mold 2 is assembled synchronously. Four inner vertical templates 21 are fixedly installed on the top of the inner bottom template 20, and the connection positions are sealed with sealing rubber strips. A positioning and reinforcement steel beam 5 is installed on the top of the inner vertical template 21 by high-strength bolts. Then, the adjustable support member 6 is installed inside the inner cavity of the inner mold 2 to provide internal support for the inner mold 2.

[0043] Nylon blocks 15 are installed at the outer bottom of the inner mold 2 by bolts. The door template 4 and multiple cavity molds 7 are installed on the outside of the inner mold 2, and the connection positions are sealed with sealing rubber strips. After installation, the inner mold 2 is integrally hoisted above the outer bottom template 10 by a hoisting device through the positioning and reinforcement steel beam 5, and the height is higher than the position during pouring to facilitate the mold closing operation.

[0044] The outer vertical template 11 and the outer special template 12 are slidably installed on the cross-shaped sliding support 3 through pulleys 32. The outer vertical template 11 and the outer special template 12 are slid to the edge of the outer bottom template 10 and fixed with high-strength bolts, and the connection positions are sealed with sealing rubber strips to complete the installation of the outer mold 1. Then, the positioning and reinforcement steel beam 5 is fixedly connected to the top of the outer mold 1 to complete the mold closing.

[0045] Step 3: Pouring and forming. Grout the pouring cavity through the bottom grouting hole 8. During grouting, observe the grouting situation through the observation port 9 and the top opening of the pouring space.
