Description

Technical Field

[0001] This utility model relates to the field of caisson construction equipment technology, and in particular to a template device for casting the walls of vertical shafts. Background Technology

[0002] In the construction of vertical shafts, cast-in-place concrete is often used to construct the shaft walls. Currently, the commonly used shaft wall formwork is spliced ​​formwork. For example, the patent with authorization announcement number "CN208023599U" discloses a caisson formwork, which includes several standard segment formworks. Each standard segment formwork includes a formwork unit and a support unit. The formwork unit includes: a panel, several main ribs, connectors, screw buckles, and back ribs. The support unit includes: diagonal supports, support shoes, and tie rods. Several main ribs are arranged in parallel on the panel. Back ribs are set on both sides of the top of the main ribs and are perpendicular to the main ribs. One side of the back rib is connected to the diagonal support through a connector. Two diagonal supports on the same standard segment formwork are connected by support shoes. Adjacent standard segment formworks are connected by screw buckles. Its structure is a typical splicing formwork. After a single pour is completed, the inner and outer formwork needs to be removed and reassembled at the next pouring ring. During the construction process, a large amount of formwork disassembly and assembly work will be generated, which consumes a lot of manpower and is inefficient. If the formwork connection is not firm during the installation process, the formwork is prone to bursting during the pouring process, which will affect the pouring quality and waste pouring materials. Utility Model Content

[0003] The purpose of this utility model is to overcome the technical problem of low work efficiency caused by the need for disassembly and reassembly of existing splicing templates before and after each pouring, and to provide a template device for pouring vertical shaft walls.

[0004] This utility model provides a template device for casting the wall of a vertical shaft, including several inner templates and several outer templates. The inner templates and outer templates are respectively arranged along the circumference of the vertical shaft, and an annular space is formed between the inner templates and outer templates for casting to form the shaft wall. Adjacent inner templates and adjacent outer templates are connected by slide rails. The slide rails are inclined, and the inclination directions of adjacent slide rails are opposite in the circumference of the vertical shaft. Adjacent inner templates and adjacent outer templates can slide relative to each other along the slide rails, so that the inner templates or the outer templates can move simultaneously along the axial and radial directions of the vertical shaft.

[0005] The template device of this application comprises several inner templates and several outer templates that are sliding splicing templates. Adjacent templates can be connected by slide rails, allowing them to slide relative to each other along the slide rails. The slide rails are inclined along the joints between adjacent templates, and the inclination directions of adjacent slide rails are opposite. Simultaneously, the slide rails act as radial limiters between adjacent templates, maintaining radial alignment and preventing radial misalignment. As adjacent templates slide along the slide rails and move axially, the circumference of the circle formed by the splicing of the templates changes in the circumferential direction due to the inclined arrangement of the slide rails. This, in turn, changes the direction of the circle. The process involves a change in diameter, meaning that each template on the circumference moves radially while simultaneously moving axially, thus enabling demolding or mold closing. After the lower section of the well wall is poured, designated templates spaced apart circumferentially are moved upwards. During this upward movement, the templates simultaneously move radially to demold; for example, the outer template can expand radially outwards for demolding, and the inner template can contract radially inwards for demolding. After the designated templates are in place, they are axially fixed, and the remaining templates are moved upwards. During this upward movement, the templates simultaneously move radially to close the mold. Specifically, the outer template can contract radially inwards for mold closing, and the inner template can expand radially outwards for mold closing. After mold closing, a new pouring space is formed between the inner and outer templates, allowing the pouring of the upper section of the well wall to continue. The template device of this application does not require complete disassembly during demolding. It can automatically complete the demolding and mold closing actions while climbing along the slide rail, eliminating the need for excessive manpower for demolding and assembly operations, saving operating costs and improving operating efficiency. In addition, the slide rail connection ensures that adjacent templates are aligned radially and that the joints are stably spliced, preventing mold bursting and grout leakage, and ensuring pouring quality.

[0006] Preferably, the inner template includes a first inner template and a second inner template, which are staggered in the circumferential direction of the shaft. The circumferential dimension of the top of the first inner template is greater than the circumferential dimension of the bottom of the first inner template, and the circumferential dimension of the top of the second inner template is smaller than the circumferential dimension of the bottom of the second inner template.

[0007] The first inner template resembles an inverted trapezoid, and the second inner template resembles a regular trapezoid. The first and second inner templates are staggered and enclose each other to form the overall inner template structure. During demolding, the first inner template can be moved upward along the shaft axis while keeping the second inner template fixed. Adjacent first and second inner templates slide relative to each other along the slide rail. At the same time, the first and second inner templates retract radially inward, leaving the inner wall surface of the shaft wall to achieve demolding. After the first inner template is moved into place, it is axially fixed. The second inner template is moved upward, and adjacent first and second inner templates slide relative to each other along the slide rail. At the same time, the first and second inner templates expand radially outward, allowing the lower part of the inner template to fit against the inner wall surface of the shaft wall to achieve mold closing. Simultaneously, the first and second inner templates are moved axially into place as a whole, forming a new pouring space with the outer template for pouring the next section of the shaft wall.

[0008] Preferably, the first inner template has a first positioning pin hole, through which a positioning pin can pass to connect the first inner template to the well wall; the second inner template has a first insertion hole, through which a connecting rod can pass to axially position the second inner template.

[0009] Preferably, the first inner template has a first insertion hole, through which a connecting rod can be inserted to axially position the first inner template; the second inner template has a first positioning pin hole, through which a positioning pin can be inserted to connect the second inner template to the well wall.

[0010] Locating pin holes or insertion holes can be opened on both the first and second inner templates, and axial positioning can be achieved by locating pins or connecting rods.

[0011] Preferably, the top of the inner template where the first positioning pin hole is located is provided with a pin hole forming block.

[0012] The pin hole forming block can protrude radially outward on the inner template and be located within the casting space. The well wall formed by casting can form pin holes at the position of the pin hole forming block. When the inner template is moved and fixed next time, the positioning pin can be driven into the first positioning pin hole on the inner template and the pin hole formed on the well wall to fix the inner template axially.

[0013] Preferably, the outer template includes a first outer template and a second outer template, which are staggered in the circumference of the shaft. The circumferential dimension of the top of the first outer template is smaller than the circumferential dimension of the bottom of the first outer template, and the circumferential dimension of the top of the second outer template is larger than the circumferential dimension of the bottom of the second outer template.

[0014] The first outer template resembles a regular trapezoidal structure, and the second outer template resembles an inverted trapezoidal structure. The first and second outer templates are staggered and enclose each other to form the overall structure of the outer template. During demolding, the first outer template can be moved upward along the axis of the shaft while keeping the second outer template fixed. Adjacent first and second outer templates slide relative to each other along the slide rail. At the same time, the first and second outer templates expand radially outward, leaving the outer wall surface of the shaft, thus achieving demolding. After the first outer template is moved into place, it is axially fixed. The second outer template is moved upward, and adjacent first and second outer templates slide relative to each other along the slide rail. At the same time, the first and second outer templates retract radially inward, allowing the lower part of the outer template to fit against the outer wall surface of the shaft, thus achieving mold closing. Simultaneously, the first and second outer templates are moved axially into place as a whole, forming a new pouring space with the inner template for pouring the next section of the shaft wall.

[0015] Preferably, the first outer template has a second positioning pin hole, through which a positioning pin can pass to connect the first outer template to the well wall; the second outer template has a second insertion hole, through which a connecting rod can pass to axially position the second outer template.

[0016] Preferably, the first outer template has a second insertion hole, through which a connecting rod can be inserted to axially position the first outer template; the second outer template has a second positioning pin hole, through which a positioning pin can be inserted to connect the second outer template to the well wall.

[0017] Locating pin holes or insertion holes can be opened on both the first and second outer templates, and axial positioning can be achieved by using locating pins or connecting rods.

[0018] Preferably, the top of the outer template where the second positioning pin hole is located is provided with a pin hole forming block.

[0019] The pin hole forming block can protrude radially inward on the outer template and be located within the casting space. The well wall formed by casting can form pin holes at the position of the pin hole forming block. This can be used to drive the positioning pin into the second positioning pin hole on the outer template and the pin hole formed on the well wall to fix the outer template axially when the outer template is moved and fixed next time.

[0020] Preferably, the first inner template and the first outer template are arranged radially correspondingly along the shaft, and the second inner template and the second outer template are arranged radially correspondingly along the shaft. The connecting rod can be simultaneously inserted into the first insertion hole and the second insertion hole to connect the second inner template and the second outer template. A driving mechanism is provided on the slide rail.

[0021] By correspondingly setting the second inner template and the second outer template, the connecting rod can pass through both the first and second insertion holes simultaneously. This allows the second inner template and the second outer template to be axially fixed to the poured well wall, preventing them from falling. The drive mechanism on the slide rail can be a hydraulic cylinder, a pneumatic cylinder, or similar mechanism, which can drive adjacent templates to slide relative to each other along the slide rail.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This utility model provides a formwork device for casting vertical shaft walls. The formwork device comprises several inner and outer formwork panels that are slidingly joined. Adjacent formwork panels can be connected by slide rails, allowing them to slide relative to each other. The slide rails are inclined along the joints between adjacent formwork panels, with opposite inclination directions. As adjacent formwork panels slide along the slide rails and move axially, the circumference of the circle formed by the splicing of the formwork panels changes in the circumferential direction, thus changing the diameter of the circle. The formwork panels on the circumference move radially while moving axially, enabling demolding or mold closing. Demolding does not require complete disassembly; the demolding and mold closing actions are automatically completed while the formwork ascends along the slide rails, eliminating the need for excessive manpower for demolding and assembly, saving operating costs and improving efficiency. Furthermore, the slide rail connection ensures radial alignment of adjacent formwork panels and stable splicing at the joints, preventing mold bursting and grout leakage, thus guaranteeing casting quality.

[0046] like Figures 1 to 11 As shown in the figure, the template device for casting the shaft wall described in this embodiment may include multiple inner templates and multiple outer templates. The multiple inner templates and multiple outer templates may be arranged along the circumference of the shaft. The multiple inner templates and multiple outer templates form an annular space for casting to form the shaft wall 9. That is, the multiple inner templates may be spliced ​​together to form a circular template structure, and the multiple outer templates may be spliced ​​together to form another circular template structure. The two circular template structures may form two concentric circles, and an annular space may be formed between the two circular template structures. Concrete may be poured in the annular space to form the shaft wall 9.

[0047] Adjacent inner formwork panels and adjacent outer formwork panels are connected by slide rails 5. The slide rails 5 are inclined, and the inclination directions of adjacent slide rails 5 are opposite in the circumferential direction of the shaft. Adjacent inner and outer formwork panels can slide relative to each other along the slide rails 5, allowing them to move simultaneously along the axial and radial directions of the shaft. In other words, the joint between two adjacent formwork panels is inclined, and the slide rails 5 are located at the joint and are also inclined along the direction of the joint. While the adjacent formwork panels move relative to each other, they can also move simultaneously along the axial and radial directions of the shaft using the inclined slide rails 5.

[0048] The template device of this application comprises multiple inner templates and multiple outer templates that are slidingly joined. Adjacent templates are connected by slide rails 5, allowing them to slide relative to each other along the slide rails 5. The slide rails 5 are inclined along the joints between adjacent templates, with opposite inclination directions. Simultaneously, the slide rails 5 act as radial limiters between adjacent templates, maintaining radial alignment and preventing misalignment. As adjacent templates slide along the slide rails 5 and move axially, the circumference of the circle formed by the joints changes due to the inclined arrangement of the slide rails 5, thus affecting the overall shape of the template. The change in the diameter of the circumference means that each template on the circumference will move radially while moving axially, thus enabling the demolding or mold closing process. After the lower section of the well wall 9 is poured, the designated templates that are spaced apart circumferentially can be moved upwards first. During the upward movement, the templates move radially to demold. For example, the outer template can be radially expanded to demold, and the inner template can be radially contracted to demold. After the designated templates are moved into place, they are axially fixed. The remaining templates are then moved upwards. During the upward movement of the remaining templates, the templates move radially to close the mold. Specifically, the outer template can be radially contracted to close the mold, and the inner template can be radially expanded to close the mold. After the mold is closed, a new pouring space can be formed between the inner and outer templates, and the pouring of the upper section of the well wall 9 can continue. The template device of this application does not require complete disassembly during demolding. It can automatically complete the demolding and mold closing actions while climbing along the slide rail 5, eliminating the need for excessive manpower for demolding and mold assembly, saving operating costs and improving operating efficiency. In addition, the connection through the slide rail 5 can ensure that adjacent templates are aligned radially and can also ensure stable splicing at the joint position, avoiding mold bursting and grout leakage, and ensuring the quality of pouring.

[0049] In this embodiment, the inner template may include a first inner template 1 and a second inner template 2. The first inner template 1 and the second inner template 2 are staggered around the circumference of the shaft. The circumferential dimension of the top of the first inner template 1 is larger than the circumferential dimension of the bottom of the first inner template 1, and the circumferential dimension of the top of the second inner template 2 is smaller than the circumferential dimension of the bottom of the second inner template 2. Similarly, the outer template includes a first outer template 3 and a second outer template 4. The first outer template 3 and the second outer template 4 are staggered around the circumference of the shaft. The circumferential dimension of the top of the first outer template 3 is smaller than the circumferential dimension of the bottom of the first outer template 3, and the circumferential dimension of the top of the second outer template 4 is larger than the circumferential dimension of the bottom of the second outer template 4. When the template is installed on the shaft wall 9, the first inner template 1 and the second outer template 4 can be regarded as similar to an inverted trapezoidal structure, and the second inner template 2 and the first outer template 3 can be regarded as similar to a regular trapezoidal structure. The first inner template 1 and the second inner template 2 can be staggered and enclosed to form the overall structure of the inner template, and the first outer template 3 and the second outer template 4 can be staggered and enclosed to form the overall structure of the outer template.

[0050] When demolding the inner template, the first inner template 1 can be moved upward along the axial direction of the shaft while the second inner template 2 remains fixed. The adjacent first inner template 1 and second inner template 2 slide relative to each other along the slide rail 5. At the same time, the first inner template 1 and the second inner template 2 retract radially inward, leaving the inner wall surface of the shaft wall 9 to achieve demolding. After the first inner template 1 is moved into place, it is axially fixed. The second inner template 2 is moved upward. The adjacent first inner template 1 and the second inner template 2 slide relative to each other along the slide rail 5. At the same time, the first inner template 1 and the second inner template 2 expand radially outward, so that the lower part of the inner template fits against the inner wall surface of the shaft wall 9 to achieve mold closing. At the same time, the first inner template 1 and the second inner template 2 are moved axially into place as a whole, which can form a new pouring space with the outer template for pouring the next section of the shaft wall 9.

[0051] Similarly, when demolding the outer template, the first outer template 3 can be moved upward along the shaft axis while the second outer template 4 remains fixed. The adjacent first outer template 3 and second outer template 4 slide relative to each other along the slide rail 5. At the same time, the first outer template 3 and the second outer template 4 expand radially outward, leaving the outer wall surface of the shaft wall 9 to achieve demolding. After the first outer template 3 is moved into place, it is axially fixed. The second outer template 4 is moved upward, and the adjacent first outer template 3 and second outer template 4 slide relative to each other along the slide rail 5. At the same time, the first outer template 3 and the second outer template 4 shrink radially inward, so that the lower part of the outer template fits against the outer wall surface of the shaft wall 9 to achieve mold closing. At the same time, the first outer template 3 and the second outer template 4 are moved axially into place as a whole, forming a new pouring space with the inner template for pouring the next section of the shaft wall 9.

[0052] Of course, the demolding process of the inner and outer formwork can be carried out separately or simultaneously; the demolding process of the inner and outer formwork can also be carried out separately or simultaneously; after the previous section of the well wall 9 is poured, the inner and outer formwork needs to be moved upward and closed into place, that is, after the annular space for pouring is formed, the next section of concrete is poured to form a new well wall 9.

[0053] In this embodiment, the first inner template 1 has a first positioning pin hole 11, through which a positioning pin 7 can pass to connect the first inner template 1 to the well wall 9; the second inner template 2 has a first insertion hole 21, through which a connecting rod 8 can pass to axially position the second inner template 2; the first outer template 3 has a second positioning pin hole 31, through which a positioning pin 7 can pass to connect the first outer template 3 to the well wall 9; the second outer template 4 has a second insertion hole 41, through which a connecting rod 8 can pass to axially position the second outer template 4.

[0054] Positioning pin holes 7 or insertion holes can be opened on the first inner template 1, the second inner template 2, the first outer template 3, and the second outer template 4, and axial positioning is achieved by positioning pins 7 or connecting rods 8. Before the first inner template 1 and the first outer template 3 are moved upward, the positioning pins 7 in the first positioning pin hole 11 and the second positioning pin hole 31 must be removed. After the first inner template 1 and the first outer template 3 are moved upward into place, positioning pins 7 need to be inserted into the positioning pin holes 7 and driven into the pin holes on the well wall 9 for axial positioning, thus fixing the first inner template 1 and the first outer template 3 axially. Then, the connecting rod 8 is removed from the insertion holes on the second inner template 2 and the second outer template 4, releasing the second inner template 2 and the first outer template 4. The second inner template 2 and the second outer template 4 are axially limited, and then the second inner template 2 and the second outer template 4 are moved upward. After the second inner template 2 and the second outer template 4 are moved into place, the connecting rod 8 is simultaneously passed through the first insertion hole 21 and the second insertion hole 41 to fix the second inner template 2 and the second outer template 4. Of course, in addition to the above-mentioned insertion hole of the positioning pin 7, the positioning pin 7 hole can also be opened on the second inner template 2 and the second outer template 4, and the second inner template 2 and the second outer template 4 can be axially positioned by the positioning pin 7. Alternatively, the insertion hole can be opened on the first inner template 1 and the first outer template 3, and the first inner template 1 and the first outer template 3 can be axially positioned by the connecting rod 8. This utility model does not specifically limit the axial positioning method of the template.

[0055] In this embodiment, a pin hole forming block 12 is provided on the top of the template where the positioning pin 7 hole is located. Specifically, if the positioning pin 7 hole is opened on the first inner template 1 and the first outer template 3, then the pin hole forming block 12 is provided on the top of the first inner template 1 and the first outer template 3. If the positioning pin 7 hole is opened on the second inner template 2 and the second outer template 4, then the pin hole forming block 12 is provided on the top of the second inner template 2 and the second outer template 4. The pin hole forming block 12 on the outer template protrudes radially inward and is located in the casting space. The pin hole forming block 12 on the inner template protrudes radially outward and is located in the casting space. The well wall 9 formed by casting can form a pin hole at the position of the pin hole forming block 12, which can be used to drive the positioning pin 7 into the first positioning pin hole 11 on the template and the pin hole formed on the well wall 9 to fix the template axially when the template is moved and fixed next time.

[0056] Optionally, the first inner template 1 and the first outer template 3 are arranged radially correspondingly along the shaft, and the second inner template 2 and the second outer template 4 are arranged radially correspondingly along the shaft. The connecting rod 8 can be simultaneously inserted into the first insertion hole 21 and the second insertion hole 41 to connect the second inner template 2 and the second outer template 4. By arranging the second inner template 2 and the second outer template 4 in a corresponding manner, the connecting rod 8 can be simultaneously inserted into the first insertion hole 21 and the second insertion hole 41, and the second inner template 2 and the second outer template 4 can be hung on the poured shaft wall 9 for axial fixation to prevent them from falling. Of course, the first inner template 1 and the first outer template 3 can also be arranged radially offset, that is, the first inner template 1 and the second outer template 4 are arranged in a corresponding manner, and the second inner template 2 and the first outer template 3 are arranged in a corresponding manner. In this case, the insertion holes opened on the second inner template 2 and the second outer template 4 can be replaced with positioning pin holes 7, that is, the positioning method of the connecting rod 8 is replaced with the positioning method of the positioning pin 7 for axial positioning. This utility model does not specifically limit the corresponding position of the inner and outer templates in the circumferential direction.

[0057] A drive mechanism 6 is provided on the slide rail 5. The drive mechanism 6 on the slide rail 5 can be a hydraulic cylinder, a pneumatic cylinder, or other mechanism, which can drive adjacent templates to slide relative to each other along the slide rail 5. Extending the hydraulic cylinder or pneumatic cylinder can drive the first inner template 1 and the first outer template 3 to move upward along the slide rail 5, and retracting the hydraulic cylinder or pneumatic cylinder can drive the second inner template 2 and the second outer template 4 to move upward. Of course, in addition to hydraulic cylinders and pneumatic cylinders, other types of drive devices can also be used for the drive mechanism 6. For example, a hoist or other lifting equipment can be used to apply an upward pulling force to the template to drive it to move upward. This utility model does not specifically limit the type of drive mechanism 6.

[0058] In summary, the template device for vertical shaft wall casting of this utility model comprises several inner templates and several outer templates that are sliding splicing templates. Adjacent templates can be connected by slide rails, allowing them to slide relative to each other along the slide rails. The slide rails are inclined along the joints between adjacent templates, and the inclination directions of the adjacent slide rails are opposite. When adjacent templates slide along the slide rails and move axially, the circumference of the circle formed by the splicing of each template changes in the circumferential direction, thereby changing the diameter of the circle. Each template on the circumference will move radially while moving axially, thus realizing the demolding or mold closing process. During demolding, there is no need for overall disassembly. The demolding and mold closing actions can be automatically completed while climbing along the slide rails, eliminating the need for excessive manpower for demolding and mold assembly operations, saving operating costs and improving operating efficiency. In addition, the slide rail connection can ensure that adjacent templates are aligned radially and can also ensure stable splicing at the joint position, avoiding mold bursting and grout leakage, and ensuring the casting quality.
