Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to a construction method for a stacked building formwork module and a column casting formwork. Background Technology

[0002] During the construction of building columns, it is necessary to erect pouring formwork. A common method is to splice steel plates around the designed location of the column. However, this method requires a long construction time, especially for some tall columns, where the efficiency of pouring formwork erection is low.

[0003] Regarding the aforementioned technologies, the applicant believes that the following defects exist: the efficiency of constructing the casting formwork for the columns is low. Summary of the Invention

[0004] To improve the efficiency of constructing the formwork for column casting, this application provides a method for constructing a stacked building formwork module and a formwork for column casting.

[0005] Firstly, the overlapping building formwork module provided in this application adopts the following technical solution:

[0006] A stackable building formwork module includes multiple formwork panels. Each formwork panel has a closed-end groove on both sides. The multiple formwork panels can be partially stacked. Adjacent formwork panels are connected to each other by sliding components. The sliding components are arranged sequentially downwards or upwards. Each sliding component includes two rollers, which are respectively installed in the grooves of two adjacent formwork panels. The rollers are connected to a rotating shaft, and the two rotating shafts are connected by a connecting rod.

[0007] By adopting the above technical solution, when the first template is pulled upwards on the side where the roller is at its highest point, the roller inside the first template drives the roller inside the second template to move upwards along the slide groove of the second template through the rotating shaft and connecting rod until the roller inside the second template moves to the upper end of the slide groove. Then, the first template is pulled upwards again, and the first template lifts the second template through the sliding component. The two rollers of the sliding component are subjected to vertical forces, and the connecting rod rotates to the vertical position, so that the first template moves above the second template and is in the same plane as the second template. Similarly, the subsequent templates are lifted and unfolded in the same plane in sequence, completing the unfolding of the template. When the stacked building template module of this application is erected, after the first template is lifted by a crane, the other templates will be lifted in sequence under the pulling force of the crane. Finally, all the templates are unfolded, and then the unfolded building template module can be installed in the design position, which improves the erection efficiency of the column casting template.

[0008] Secondly, the construction method for the casting formwork of the column provided in this application adopts the following technical solution:

[0009] A construction method for casting formwork of columns includes the following steps:

[0010] Prefabrication of building formwork modules: The formwork is processed according to the design drawings. Then, the number of formwork modules is selected according to the design height of the columns. The selected formwork modules are connected in sequence using the rollers, the rotating shaft and the connecting rod to complete the prefabrication of building formwork modules.

[0011] Building formwork module deployment: The building formwork module is transported to the construction site and the formwork is erected so that the slide is upright. Then, a crane is used to connect the upper end of the first formwork and lift the first formwork until all the formwork is lifted and is in the same plane; the other building formwork modules are deployed using the same method.

[0012] Construction formwork module installation: After all the construction formwork modules have been unfolded, all the construction formwork modules are hoisted to the design position, with the formwork of adjacent construction formwork modules abutting each other, and the construction formwork modules surround each other to form the pouring space for the column;

[0013] Building formwork module fixing: Multiple sets of fixing modules are installed around the building formwork module, and the fixing modules fix all the formwork.

[0014] By adopting the above technical solution, and because multiple sets of templates are unfolded before installation and splicing, mutual interference between the various building template modules can be avoided during the unfolding process. After the multiple sets of building template modules are unfolded and spliced, they surround to form the pouring space for the column, thus completing the construction of the column pouring template and improving the construction efficiency of the column pouring template. When dismantling the building template modules, the fixed modules are removed first, and then the top template is pried outward, so that the top template moves outward, and then moves downward until the upper end of the roller and the slide groove abuts, with the top template stacked on the outside of the next top template. The same method is used to stack the subsequent templates in sequence, thereby completing the dismantling of the building template modules, which is convenient and quick.

[0015] Preferably, the first templates of each building template module are connected by hinges that avoid the slide groove and the sliding assembly.

[0016] By adopting the above technical solution and connecting them with hinges, all building formwork modules can be unfolded at once. During the unfolding process, the distance between each formwork needs to be manually controlled to avoid interference between the building formwork modules and the sliding components.

[0017] Preferably, the rollers, the pivots, and the connecting rods of two adjacent sets of building template modules are vertically staggered.

[0018] By adopting the above technical solution, interference between the sliding components on adjacent building formwork modules is avoided when they are spliced ​​together, thereby improving the splicing efficiency of building formwork modules.

[0019] Preferably, the fixing module includes a first fixing plate and a second fixing plate, which are installed on the template at intervals. The first fixing plate and the second fixing plate are connected end to end to form a frame shape and surround the building template module.

[0020] By adopting the above technical solution, the first fixing plate and the second fixing plate fix the unfolded building template module, keeping the building template module stable in the unfolded state.

[0021] Preferably, each template has multiple connecting holes, the first fixing plate has a positioning pin that matches the connecting holes, the second fixing plate has a pin hole that aligns with the connecting holes, the positioning pin is installed in the connecting hole, the second fixing plate is connected to the template by a pin, and the pin is inserted into the pin hole and the connecting hole.

[0022] By adopting the above technical solution, the first fixing plate and the second fixing plate can be easily installed on the corresponding positions on the template through the cooperation of the positioning pin and the positioning hole.

[0023] Preferably, the second fixing plate has screws at both ends, the screws pass through the first fixing plate, and nuts are installed on the screws, the nuts pressing the first fixing plate.

[0024] By adopting the above technical solution, the nuts and screws fix the first fixing plate and the second fixing plate to each other. During installation, after aligning the first fixing plate and the second fixing plate, tighten the nuts to fix the first fixing plate and the second fixing plate, which facilitates installation.

[0025] Preferably, the second fixing plate has elbows at both ends, and the first fixing plate has through holes at both ends, with the elbows passing through the through holes.

[0026] By adopting the above technical solution, the elbow can restrict the axial movement of the second fixed plate and improve the connection between the first fixed plate and the second fixed plate.

[0027] In summary, this application includes at least one of the following beneficial technical effects: When the first template is pulled upwards on the side where the roller is at its highest point, the roller inside the first template drives the roller inside the second template to move upwards along the slide groove of the second template through the rotating shaft and connecting rod until the roller inside the second template moves to the upper end of the slide groove. Then, the first template continues to be pulled upwards, and the first template lifts the second template through the sliding component. The two rollers of the sliding component are respectively subjected to vertical forces, and the connecting rod rotates to the vertical position, so that the first template moves above the second template and is in the same plane as the second template. Similarly, the subsequent templates are lifted and unfolded in the same plane in sequence, completing the unfolding of the template. When the stacked building template module of this application is erected, after the first template is lifted by a crane, the other templates will be lifted in sequence under the pulling force of the crane. Finally, all the templates are unfolded, and then the unfolded building template module can be installed in the design position, which improves the erection efficiency of the column casting template.

[0036] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0037] This application discloses a construction method for a stacked building formwork module and a column casting formwork.

[0038] Reference Figure 1 and Figure 2 A stacked building formwork module includes multiple formwork panels 11, each made of steel plate. Each formwork panel 11 has a closed-end groove 12 on both sides, with a U-shaped cross-section. The multiple formwork panels 11 are stacked sequentially from left to right, with a predetermined vertical offset. Adjacent formwork panels 11 are connected to each other via sliding components 13. The leftmost and rightmost formwork panels 11 are connected to one set of sliding components 13, and the middle formwork panel 11 is connected to two sets of sliding components 13. The sliding components 13 are lowered sequentially from left to right. Among the two sets of sliding components 13 connected to the middle formwork panel 11, the sliding component 13 connecting the left formwork panel 11 is positioned above the sliding component 13 connecting the right formwork panel 11. The sliding assembly 13 includes two rollers 131, which are matched with slide grooves 12. The two rollers 131 are respectively installed in the slide grooves 12 of two adjacent templates 11. The slide grooves 12 can prevent the rollers 131 from disengaging. The rollers 131 are connected to rotating shafts 132, and the two rotating shafts 132 are connected by a connecting rod 133. The rotating shafts 132 rotatably connect to the connecting rod 133. The slide grooves 12 of the leftmost template 11 and the rightmost template 11 each contain only one roller 131, while the slide grooves 12 of the middle template 11 each contain two rollers 131, and these two rollers 131 belong to two different sets of sliding assemblies 13. The number of sliding plates is determined according to actual needs; in this embodiment, five sliding plates are preferred.

[0039] Reference Figure 1 and Figure 2The right side of the template 11 is the pouring surface, and multiple crisscrossing reinforcing ribs 14 are installed on the left side of the template 11. The multiple reinforcing ribs 14 are connected in a grid pattern, and the outer surfaces of each reinforcing rib 14 are coplanar with the sides of the template 11. The left corner of the reinforcing rib 14 located at the upper end of the template 11 is set as a rounded corner 15. The rounded corner 15 is tangent to the upper end surface of the reinforcing rib 14 and tangent to the left side surface of the reinforcing rib 14. The axis of the rounded corner 15 coincides with the axis of the roller 131 when it is in close contact with the upper end of the slide groove 12, so that the template 11 can move from one side of the template 11 to the top of the template 11 while closely following the rounded corner 15, reducing the occurrence of the template 11 getting stuck.

[0040] The implementation principle of a stacked building formwork module in this application embodiment is as follows: For ease of explanation, refer to... Figure 3The template 11 and sliding components 13 are numbered. The five sliding plates from left to right are numbered as template 11a, template 21b, template 31c, template 41d, and template 51e. The four sliding components 13 from left to right are numbered as sliding component 13a, sliding component 23b, sliding component 33c, and sliding component 44d. Sliding component 13a connects template 11a and template 21b. Sliding component 13b connects template 21b and template 31c. Sliding component 13c connects template 31c and template 41d. Sliding component 13d connects template 41d and template 51e. The building template modules 1 are stacked and transported to the construction site. During construction, a tower crane or electric hoist is used to pull the first template 11a upward. As the first template 11a moves upward, one roller 131 of the first sliding component 13a is restricted by the lower end of the sliding groove 12 of the first template 11a. Therefore, the first sliding component 13a moves upward with the first template 11a. The other roller 131 of the first sliding component 13a moves upward along the sliding groove 12 of the second template 11b. At this time, the second template 11b remains stationary. When the roller 131 of the first sliding component 13a located in the groove 12 on the second template 11b moves to the upper end of the groove 12 of the second template 11b, it is restricted by the end of the groove 12. As the first template 11a continues to be pulled upward, the first sliding component 13a applies an upward force to the second template 11b. Due to the different forces on the two rollers 131 of the first sliding component 13a, the connecting rod 133 rotates under torque, causing the first template 11a to move upward and to the right simultaneously until the forces on the two rollers 131 of the first sliding component 13a are on the same straight line. At this time, the first template 11 is above the second template 11b and the lower end of the first template 11a abuts against the upper end of the second template 11b. The right side of the first template 11a and the right side of the second template 11b are in the same plane. Continue pulling template 11a upwards. Template 11a, through sliding component 13a, moves template 11b upwards. Similarly, sliding component 13b moves upwards with template 11b, until the right side of template 11b and template 11c are in the same plane. Continue pulling template 11a upwards, and then pull up templates 11c and 11d in sequence, so that the right sides of templates 1 to 11e are in the same plane, completing the unfolding of building template module 1. When folding, first move template 11a to the left, so that template 11a moves along the rounded corner of the upper end of template 11b to the left side of template 11b, and then descends to the folding position corresponding to template 11b.The same operation is used to collapse templates 11b, 11c, and 11d, resulting in building template module 1, which consists of templates 11a, 11b, 11c, 11d, and 11e.

[0041] This application also discloses a construction method for a column casting formwork 11.

[0042] Reference Figure 4 and Figure 5 A construction method for a column casting formwork 11 includes the following steps:

[0043] Prefabrication of Building Formwork Module 1: Process formwork 11 according to the design drawings to prefabricate the above-mentioned building formwork module 1. The number of formwork 11 is selected according to the design height of the column, and the selected formwork 11 is connected in sequence by rollers 131, rotating shafts 132 and connecting rods 133 to complete the prefabrication of building formwork module 1. After the prefabrication is completed, the building formwork module 1 is stacked for easy transportation.

[0044] Formwork Module 1 Deployment: Formwork Module 1 is transported to the construction site, and the formwork 11 is erected so that the slide 12 is upright. Then, a tower crane is used to connect the upper end of the leftmost formwork 11 and lift it up until all the formwork 11s of Formwork Module 1 are lifted and are basically in the same plane, completing the deployment of Formwork Module 1. Other Formwork Modules 1 are deployed using the same method. This embodiment uses four Formwork Modules 1 for the casting of square columns.

[0045] Installation of building formwork module 1: After all building formwork modules 1 have been unfolded, all building formwork modules 1 are hoisted to the design position. The formwork 11 of adjacent building formwork modules 1 abut against each other, and the overlap width of adjacent formwork 11 is 3-5mm, avoiding interference from connecting rod 133 and rotating shaft 132. Each building formwork module 1 surrounds to form the pouring space of the column.

[0046] Building formwork module 1 fixing: Multiple sets of fixing modules 2 are installed around the building formwork module 1. The fixing modules 2 fix all the formwork 11 to prevent the building formwork module 1 from automatically collapsing.

[0047] The leftmost templates 11 of each building template module 1 are connected sequentially by hinges. Two building template modules 1 are disconnected from each other to prevent the building template modules 1 from being unfolded into a frame shape. The hinges avoid the slide groove 12 and the sliding component 13. When the building template modules 1 are unfolded, all building template modules 1 can be unfolded at once. After unfolding, the two disconnected building template modules 1 are connected to each other to form the pouring space of the column.

[0048] Reference Figure 6 The fixing module 2 includes a first fixing plate 21 and a second fixing plate 24. The first fixing plate 21 and the second fixing plate 24 are spaced apart and connected end to end to form a frame and tightly hold the unfolded building template module 1. The first fixing plate 21 and the second fixing plate 24 are both installed on the template 11. Each template 11 has a reinforcing rib 14 with multiple connecting holes for positioning the first fixing plate 21 and the second fixing plate 24. The multiple connecting holes are distributed in multiple rows and columns. The first fixing plate 21 is fixed with multiple positioning pins 22 that match the connecting holes. The multiple positioning pins 22 correspond one-to-one with the multiple connecting holes in the same row. The positioning pins 22 are inserted into the connecting holes and are interference-fitted with the connecting holes to keep the positioning pins 22 stable in the connecting holes. The cooperation between the positioning pins 22 and the connecting holes makes the first fixing plate 21 stable in the corresponding position of the template 11. The second fixing plate 24 has multiple through pin holes 25, which are aligned with multiple connecting holes in the same row. Pins 26 are connected to the pin holes 25, passing through the pin holes 25 and the connecting holes. The pins 26, pin holes 25, and connecting holes have the same diameter, and the pins 26 stabilize the second fixing plate 24 in the corresponding position on the template 11. The first fixing plate 21 has through holes 23 at both ends, and the second fixing plate 24 has screws 27 at both ends. The screws 27 pass through the through holes 23, and nuts 28 are installed on the screws 27. The nuts 28 press against the first fixing plate 21, and the first fixing plate 21 and the second fixing plate 24 are fixedly connected through the cooperation of the nuts 28 and the screws 27.

[0049] In another embodiment, the heights of the leftmost templates 11 of two adjacent sets of building template modules 1 are different, and the heights of the rightmost templates 11 of two adjacent sets of building template modules 1 are also different. Furthermore, the sum of the heights of the leftmost templates 11 and the rightmost templates 11 of all building template modules 1 is equal, and the heights of the middle templates 11 of each building template module 1 are all equal, so that the heights of each building template module 1 after unfolding are equal. After unfolding, the heights of the sliding components 13 on adjacent building template modules 1 are different, so that the sliding components 13 on adjacent building template modules 1 are staggered in the vertical direction to reduce interference.

[0050] In another embodiment, elbows are provided at both ends of the second fixing plate 24. The elbows are right-angled and pass through the through hole 23. During installation, one end of the elbow passes through the through hole 23 first, and then the second fixing plate 24 is rotated 90 degrees so that the other end of the elbow also passes through the through hole 23. The elbows can restrict the axial movement of the second fixing plate 24 and improve the connection between the first fixing plate 21 and the second fixing plate 24.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
