Description

Technical Field

[0001] The present invention relates to the technical field of column base pouring, and particularly relates to a drawer-type circulating formwork for secondary pouring of steel column bases and a using method thereof. Background Art

[0002] The main purpose of secondary pouring of the steel column base is to prevent the anchor bolts from being damaged due to environmental erosion, which may lead to structural damage. When the anchor bolts are damaged, there are significant potential safety hazards in the overall structure. In addition, if the quality of secondary pouring is qualified, it will also participate in the structural force, thereby improving the structural safety.

[0003] During the pouring construction process, the conventional construction operation is to use wooden formwork to set up the formwork, then pour concrete, and use the self-flow of the concrete to fill the area under the column base. However, there are many problems with the above operations. First, the steel column will block the line of sight, so it is impossible to judge whether the area under the column base is poured densely. Especially in large buildings, the cross-sectional size of the steel column is large, and the area that is not poured densely may be larger. Second, due to the temporary setting up of the formwork, it is impossible to determine whether the amount of injected concrete is sufficient, and thus it is impossible to determine whether the area under the column base is poured densely based on the amount of concrete used. The conventional method is to determine that enough concrete has been injected when the concrete is flush with the column base. However, since it is impossible to determine whether the area under the column base is dense, the above method cannot guarantee the dense pouring of the column base. Third, if the secondary pouring material is fine aggregate concrete and only relies on the self-flow of the concrete to fill the column base, the phenomenon of non-dense pouring is more common. In actual construction, in order to avoid or improve the occurrence of this phenomenon, the common method is to use more expensive grouting material instead of fine aggregate concrete for grouting to ensure the dense pouring of the column base. However, if the secondary pouring material in the original design drawing is fine aggregate concrete and it cannot be adjusted to grouting material through drawing review or change, in order to ensure the pouring quality, if the construction unit adjusts it to grouting material by itself, it will increase the project cost additionally. In addition, the formwork material of the commonly used wooden formwork has a limited number of turnover times, and the setting up is time-consuming and laborious, which is not conducive to later recycling and reuse. The present invention provides a drawer-type circulating formwork for secondary pouring of steel column bases and a using method thereof to solve the above problems. Summary of the Invention

[0004] The present invention provides a drawer-type circulating formwork for secondary pouring of steel column bases and a using method thereof. The specification and size of the formwork are determined, so that the amount of injected concrete can be determined, and whether the area under the column base is poured densely can be determined according to the height of the concrete, thereby ensuring the structural stability of the column base.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: A drawer-type circulating formwork for the secondary casting of steel column bases, which is used for the secondary casting of the column bases of steel columns or composite columns, includes a casting formwork and a measurement partition. The casting formwork is arranged on the ground and is located on the outer periphery of the steel column base. The casting formwork includes a fixed formwork and a movable formwork. The fixed formwork and the movable formwork are oppositely arranged and are both U-shaped frames. The inner sides of the movable formwork and the fixed formwork overlap and fit with each other to form a rectangular frame. Before casting, the inner ends of the movable formwork and the fixed formwork are butted, and the measurement partition is placed at the inner end of the fixed formwork, separating the inner cavities of the fixed formwork and the movable formwork to form a casting cavity and a measurement cavity respectively. The casting cavity is used for closing the formwork to cast the column base, and the measurement cavity is used for injecting concrete and measuring the amount of concrete used. During casting, the measurement partition is removed, and the inner sides of the movable formwork and the fixed formwork overlap, and the casting cavity and the measurement cavity coincide.

[0006] Further, the fixed formwork includes a fixed side formwork and a fixed edge formwork. The fixed side formwork is arranged in pairs on the outer side of the fixed edge formwork to form a U-shaped frame. The movable formwork includes a movable side formwork and a movable edge formwork. The movable side formwork is arranged in pairs on the outer side of the movable edge formwork to form a U-shaped frame. The inner sides of the movable side formwork and the fixed side formwork overlap and fit with each other. Before casting, the fixed edge formwork, the fixed side formwork, the movable edge formwork and the movable side formwork enclose a rectangular inner cavity. When closing the formwork for casting, the fixed edge formwork, the fixed side formwork and the movable edge formwork enclose a rectangular inner cavity.

[0007] Further, a transfer assembly is arranged on the outer side of the fixed formwork, and the transfer assembly is arranged in groups on the outer side of the fixed edge formwork; a formwork closing assembly is arranged on the outer side of the movable formwork, and the formwork closing assembly is arranged on the outer side of the movable edge formwork.

[0008] Further, extension pieces are arranged on both the fixed formwork and the movable formwork, and the extension pieces are detachably arranged at the inner ends of the fixed side formwork and the movable side formwork.

[0009] Further, both the fixed side formwork and the movable side formwork are U-shaped groove structures. The movable side formwork is located in the groove of the fixed side formwork, and moving wheels are arranged in the groove of the movable side formwork.

[0010] Further, the fixed side formwork is connected to the fixed edge formwork by bolts, the movable side formwork is connected to the movable edge formwork by bolts, and adjusting holes are arranged at intervals at the outer ends of the fixed edge formwork and the movable edge formwork.

[0011] Further, the measurement partition includes a partition and a support handle. The support handle is arranged in groups on the outer side of the partition. The partition is vertically arranged between the two fixed side formworks, and the outer end of the partition contacts the inner wall of the fixed side formwork.

[0012] Furthermore, a connection plate is provided on the partition plate, and the connection plate is detachably arranged at the outer end of the partition plate.

[0013] Furthermore, marking lines are provided on the measurement partition plate.

[0014] A method for using a drawer-type circulating formwork for secondary pouring of steel column bases includes the following steps: S1, Adjustment preparation: Mark the positioning lines on the outer side of the steel column base to mark the pouring range, which serves as the placement position of the formwork. Then, adjust the sizes of the fixed formwork, movable formwork, and measurement partition plate according to the column base size. S2, Place the formwork: First, transfer the fixed formwork and lay it flat at the marked positioning place. Then, adjust the position of the movable formwork to align it with the fixed formwork, and push the movable formwork so that its inner end overlaps and fits with the inner end of the fixed formwork, and snap it to form a rectangle. Then, vertically clamp the measurement partition plate in the fixed formwork to separate the inner cavities of the fixed formwork and the movable formwork to form a pouring cavity and a measurement cavity respectively. S3, Quantitative feeding: Pour concrete into the measurement cavity formed by the measurement partition plate and the movable formwork. Determine the amount of poured concrete according to the marking lines on the measurement partition plate. Stop pouring concrete after the amount of concrete meets the standard. S4, Close the formwork and pour: Remove the measurement partition plate. The concrete flows into the pouring cavity under self-flow and manual assistance. During the flowing process of the concrete, manually push the movable formwork towards the fixed formwork. Under the push of the movable formwork and manual assistance, the concrete in the movable formwork is pushed into the pouring cavity. When the movable formwork and the fixed formwork completely overlap to complete the closing of the formwork, at this time, the concrete completely flows into the pouring cavity. S5, Demold the formwork: When the concrete reaches the demolding condition, demold the formwork. Push the movable formwork outwards until it disengages from the overlap with the fixed formwork, then remove the fixed formwork. Then, erect the fixed formwork and transfer the fixed formwork and the movable formwork to the next construction position.

[0015] The beneficial effects of the present invention are as follows: The structure and size of the steel formwork are fixed. With the cooperation of the measurement partition plate, the amount of injected concrete can be determined. After closing the formwork, if the concrete is flush with the steel column, it indicates that the pouring under the column base is dense, thereby ensuring the dense pouring of the column base and further ensuring the stability of the structure, avoiding potential safety hazards, and also avoiding the cost increase caused by using more expensive grouting materials. Adopting a split-type steel formwork and the method of first grouting and then closing the formwork can achieve precise control of the amount of injected concrete, and the operation of closing the formwork also has the function of filling the concrete, enabling the concrete to fully fill under the column base and improving the density of pouring. The steel formwork has the advantages of stable structure, reusable, and simple operation, which can effectively reduce the use cost and improve the construction efficiency.

Detailed Description of the Invention

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0020] As shown Figure 1 in 2 Figures 3 and 4, a drawer-type circulating formwork for the secondary casting of steel column bases, which is used for the secondary casting of the column bases of steel columns or composite columns, includes a casting formwork and a measuring partition 3. The casting formwork is arranged on the ground and is located on the outer periphery of the steel column base. The casting formwork includes a fixed formwork 1 and a movable formwork 2. The fixed formwork 1 and the movable formwork 2 are arranged oppositely and are both U-shaped frames. The inner sides of the movable formwork 2 and the fixed formwork 1 overlap and fit with each other to form a rectangular frame. Before casting, the inner end of the movable formwork 2 is docked with the inner end of the fixed formwork 1, and the measuring partition 3 is placed at the inner end of the fixed formwork 1 to separate the inner cavities of the fixed formwork 1 and the movable formwork 2 and form a casting cavity and a measuring cavity respectively. The casting cavity is used for closing the formwork to cast the column base, and the measuring cavity is used for injecting concrete and measuring the amount of concrete. During casting, the measuring partition 3 is removed, and the inner sides of the movable formwork 2 and the fixed formwork 1 overlap, and the casting cavity and the measuring cavity coincide.

[0021] As shown Figure 1 in 2 Figures 3 and 4, the specific principle of the present invention is as follows: The fixed formwork 1 and the movable formwork 2 are arranged oppositely and their inner sides overlap with each other to form a rectangular casting formwork. Before casting, the inner end of the movable formwork 2 is clamped with the inner end of the fixed formwork 1 to form a rectangular frame, and then the measuring partition 3 is vertically clamped between the two fixed side formworks 12 of the fixed formwork 1, and the inner cavity surrounded by the fixed formwork 1 and the movable formwork 2 forms a casting cavity and a measuring cavity. The measuring cavity is used to determine the amount of concrete injected. Before casting, the required amount of concrete has been calculated according to the specification size of the column base, and then the measuring function of the measuring cavity is used to ensure that the concrete injected into it is the required amount. When injecting concrete, when the height of the concrete reaches the corresponding marking line on the measuring partition 3, the amount of concrete injected at this time is the calculated required amount, and then the injection of concrete is stopped. Then the measuring partition 3 is removed, and the concrete is allowed to flow by itself, assisted manually and at the same time the movable formwork 2 is pushed towards the direction of the fixed formwork 1 to close the formwork, and then the concrete in the measuring cavity is pushed into the casting cavity. When the formwork is completely closed, all the concrete in the measuring cavity is also pushed into the casting cavity to cast the column base. Since the amount of concrete injected is the same as the calculated required amount, after the movable formwork 2 and the fixed formwork 1 are completely closed, when the height of the concrete is the same as the designed height after stirring and vibrating, it also proves that the space under the column base has been completely filled and the column base has been cast densely. If the height of the concrete is higher than the designed height, it means that there is still space under the column base that has not been cast densely, and it is necessary to continue vibrating and draining until the height of the concrete in the casting cavity is the same as the designed height. Whether the column base is cast densely is indirectly deduced in the above way, ensuring the stable safety of the structure.

[0022] As shown Figure 1 in2 As shown in the figure, in the first embodiment of the present invention, a fixed template 1 and a movable template 2 with fixed size specifications are adopted. The fixed template 1 includes a fixed edge template 11 and fixed side templates 12. The fixed edge template 11 is arranged vertically, and the fixed side templates 12 are arranged in pairs on the outer sides of the fixed edge template 11 to form a U-shaped frame. The movable template 2 includes a movable edge template 21 and movable side templates 22. The movable edge template 21 is arranged vertically, and the movable side templates 22 are arranged in pairs on the outer sides of the movable edge template 21 to form a U-shaped frame. During installation, the fixed template 1 and the movable template 2 are arranged opposite to each other. The inner sides of the movable side templates 22 and the inner sides of the fixed side templates 12 overlap and fit together to enclose a closed rectangular inner cavity. Before pouring, the fixed edge template 11, the fixed side templates 12, the movable edge template 21, and the movable side templates 22 enclose a rectangular inner cavity. At this time, the inner ends of the movable side templates 22 are clamped with the inner ends of the fixed side templates 12. When closing the mold and pouring, the movable side templates 22 are pushed inward until they completely overlap with the fixed side templates 12. At this time, the fixed edge template 11, the fixed side templates 12, and the movable edge template 21 enclose a rectangular inner cavity.

[0023] As Figure 5 、 7 As shown in the figure, further, a transfer component 13 is arranged outside the fixed template 1. The transfer component 13 is arranged in groups on the side walls outside the fixed edge template 11. The transfer component 13 is used to transfer the fixed template 1. During construction, the fixed template 1 is laid down flat and cooperates with the movable template 2 for concrete pouring. When transferring, the fixed template 1 is erected. At this time, the fixed template 1 stands on the ground through the transfer component 13, and the fixed template 1 is pushed to move by using the transfer component 13, effectively reducing the workload during transfer. A mold closing component 23 is arranged outside the movable template 2. The mold closing component 23 is arranged outside the movable edge template 21. The mold closing component 23 is used to push the movable template 2 for mold closing and transfer.

[0024] Further, the transfer component 13 is a roller group, and two groups of roller groups are arranged in total. The mold closing component 23 is a push handle arranged obliquely, which is convenient for personnel to operate.

[0025] As Figure 1 、 2As shown in FIGS. 5 and 7, in the second embodiment of the present invention, a fixed template 1 and a movable template 2 with adjustable size specifications are adopted, and their sizes are adjustable both horizontally and vertically. When adjusting horizontally, an extension piece 14 detachably arranged at the inner ends of the fixed side template 12 and the movable side template 22 is used. The horizontal length is adjusted by installing the extension piece 14 or replacing the extension piece 14 with the required specification. When adjusting, the extension pieces 14 on the fixed side template 12 and the movable side template 22 need to be replaced synchronously; when adjusting vertically, it is achieved by adjusting the position of the fixed side template 12 on the fixed edge template 11 and the position of the movable side template 22 on the movable edge template 21. When adjusting, the fixed template 1 and the movable template 2 need to be adjusted synchronously, and at the same time, the length of the measurement partition 3 also needs to be adjusted synchronously.

[0026] As Figure 5 , 7 shown, extension pieces 14 are provided on both the fixed template 1 and the movable template 2, and the extension pieces 14 are detachably connected to the inner ends of the fixed side template 12 and the movable side template 22 by bolts; the extension piece 14 at the inner end of the fixed side template 12 has the same structure as the fixed side template 12, and the extension piece 14 at the inner end of the movable side template 22 has the same structure as the movable side template 22.

[0027] As Figure 6 , 8 shown, further, both the fixed side template 12 and the movable side template 22 are U-shaped groove structures and are both arranged with the openings facing downwards. The movable side template 22 is located in the groove of the fixed side template 12 and moves along the groove shape of the fixed side template 12. Movable wheels are arranged in the groove of the movable side template 22.

[0028] Further, movable wheels can be arranged on the extension piece 14 at the inner end of the movable side template 22 according to the specification or requirement.

[0029] Further, both the fixed side template 12 and the movable side template 22 are vertically arranged steel plates, the movable side template 22 is attached to the outer wall of the fixed side template 12, and movable wheels are arranged on the outer side of the steel plate of the movable side template 22.

[0030] As Figure 5 , 7 shown, further, the fixed side template 12 is connected to the fixed edge template 11 by bolts, the movable side template 22 is connected to the movable edge template 21 by bolts, and adjustment holes are arranged at intervals at the outer ends of the fixed edge template 11 and the movable edge template 21. When adjusting, the position of the fixed side template 12 is adjusted along the length direction of the fixed edge template 11, and the position of the movable side template 22 is adjusted along the length direction of the movable edge template 21 to achieve the adjustment of the longitudinal dimension.

[0031] As Figure 9, 10 As shown in Fig. 11, further, the measurement partition 3 includes a partition 31 and a support handle 32. The support handles 32 are arranged in groups on the outer side of the partition 31, and the height of the support handle 32 is the same as the height of the partition 31, so that the measurement partition 3 is in a vertical state when placed, and thus the concrete volume can be accurately measured. When placed, the partition 31 is vertically arranged between the two fixed side formworks 12, and the support handle 32 is located on one side of the pouring cavity. When the concrete in the measurement cavity presses against the partition 31, the support handle 32 supports the partition 31 to keep the measurement partition 3 stable. The outer end of the partition 31 contacts and fits with the inner wall of the fixed side formwork 12 to prevent the concrete from flowing.

[0032] As Figure 9 , 10 shown in Fig. 12, further, a connecting plate 33 is provided on the partition 31 to cooperate with the adjustable sizes of the fixed formwork 1 and the movable formwork 2. The connecting plate 33 is detachably arranged at the outer end of the partition 31 by bolts.

[0033] Further, a marking line is provided on the measurement partition 3. The marking line is provided on the partition 31 for measuring the concrete volume. Before pouring, the specification size of the column foot is determined according to the scribed positioning, and then the amount of concrete required for pouring the column foot is calculated, and thus the amount of concrete to be injected into the measurement cavity can be determined. Since the area of the measurement cavity is a definite value after the formworks are assembled, only the height of the injected concrete needs to be calculated. When injecting concrete, when the surface of the concrete coincides with the corresponding marking line on the measurement partition 3, the amount of injected concrete at this time is the required amount of concrete.

[0034] As Figure 1 , 2 shown in Fig. 13, a method for using a drawer-type circulating formwork for secondary pouring of steel column feet includes the following steps. S1, adjustment preparation: Mark the pouring range on the outer side of the steel column foot by scribed positioning as the placement position of the formwork, and then adjust the sizes of the fixed formwork 1, the movable formwork 2, and the measurement partition 3 according to the column foot size. S2, formwork placement: First, transfer the fixed formwork 1 and place it flat at the scribed positioning position. Then, adjust the position of the movable formwork 2 to align it with the fixed formwork 1, and push the movable formwork 2 to overlap and fit its inner end with the inner end of the fixed formwork 1 and be mutually clamped to form a rectangular inner cavity. Then, vertically clamp the measurement partition 3 in the fixed formwork 1 to separate the inner cavities of the fixed formwork 1 and the movable formwork 2 to form a pouring cavity and a measurement cavity respectively. S3, quantitative feeding: Inject concrete into the measurement cavity formed by the measurement partition 3 and the movable formwork 2, and determine the amount of poured concrete according to the marking line on the measurement partition 3. Stop injecting concrete after the amount of concrete reaches the standard. S4, Mold Closing and Pouring: Remove the measurement partition 3. Under the action of self-flow and manual assistance, the concrete flows into the pouring cavity. During the flowing process of the concrete, manually push the movable formwork 2 towards the fixed formwork 1 to close the mold. At the same time, manually assist in pushing the concrete into the pouring cavity. Under the push of the movable formwork 2 and manual assistance, the concrete in the movable formwork 2 is pushed into the pouring cavity. When the movable formwork 2 and the fixed formwork 1 completely overlap, the mold closing is completed. At this time, the concrete completely flows into the pouring cavity, and then stirring and vibration are carried out. When the height of the stabilized concrete is the same as the designed height, it also proves that the space under the column base has been completely filled and the column base has been densely poured, and then the concrete is allowed to solidify; S5, Formwork Removal: When the concrete reaches the formwork removal condition, remove the formwork. First, withdraw the movable formwork 2 outwards until it disengages from the overlap with the fixed formwork 1, then remove the fixed formwork 1, and then erect the fixed formwork 1. Use the transfer component 13 to transfer the fixed formwork 1, and push the movable formwork 2 to move using the moving wheels below it to transfer the fixed formwork 1 and the movable formwork 2 to the next construction position for continuous construction until all column bases are constructed.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.

Then vertically clamp the measurement partition plate (3) in the fixed template (1) to separate the inner cavities of the fixed template (1) and the movable template (2) to form a pouring cavity and a measurement cavity respectively. S3, Quantitative feeding: Pour concrete into the measurement cavity formed by the measurement partition plate (3) and the movable template (2). Determine the amount of poured concrete according to the marking lines on the measurement partition plate (3). Stop injecting concrete after the amount of concrete meets the standard. S4, Close the mold and pour: Remove the measurement partition plate (3). The concrete flows into the pouring cavity under its own gravity and with manual assistance. During the flow of the concrete, manually push the movable template (2) towards the fixed template (1). Under the push of the movable template (2) and with manual assistance, the concrete in the movable template (2) is pushed into the pouring cavity. When the movable template (2) and the fixed template (1) completely overlap, the mold is closed. At this time, the concrete completely flows into the pouring cavity. S5, Demold the template: When the concrete reaches the demolding condition, demold the template. Push the movable template (2) outwards until it disengages from the overlap with the fixed template (1), then remove the fixed template (1), then erect the fixed template (1), and transfer the fixed template (1) and the movable template (2) to the next construction position.
