Description

Technical Field

[0001] This invention belongs to the technical field of grouting tools between steel columns and foundations, specifically relating to a grouting module between steel columns and foundations. Background Technology

[0002] Steel-concrete composite pipes, steel-concrete composite sections, and composite floor slabs are all used to varying degrees in landmark buildings, super high-rise buildings, and large convention centers, employing combined concrete and steel structures. Currently, the connection between steel columns and concrete foundations often involves pre-embedded anchor bolts in the foundation concrete, which are then bolted to the steel column base plates. The elevation and verticality of the steel columns are controlled by shims or bolts under the base plates. Finally, secondary grouting is performed between the column base plates and the foundation to ensure a tight bond between the steel columns and the foundation, meeting load transfer requirements. However, secondary grouting increases the difficulty of formwork erection, making it difficult to guarantee the quality of formwork installation, frequently resulting in bulging and grout leakage. This leads to significant waste of grouting materials, low formwork installation efficiency, and increased construction costs.

[0003] Steel columns are the main load-bearing components in building structures, requiring high installation precision, especially the precise connection between the first section of the steel column and the foundation. The method of fine-tuning to ensure the verticality of the steel column is crucial. Currently, methods for correcting the first section of the steel column mainly include pre-setting concrete or iron shims, inserting wedges around the column, and directly setting a single nut on the bottom of the steel column for correction. While these methods can adjust the deviation of the steel column within the allowable range, the construction is relatively complex. Grouting between the base of the steel column and the foundation requires temporary assembly of formwork, usually supported by square timber and fixed with nails, resulting in a large workload, low efficiency, and difficulty in disassembly and assembly, leading to low formwork reuse rates. When grouting using temporary formwork, it is difficult to ensure that the concrete thickness around the steel column is uniform. Using a single nut for correction is difficult to control due to the influence of the bolt holes in the steel column base plate, and it is also difficult to ensure that the thickness fully meets design standards. Summary of the Invention

[0004] In view of the defects and problems in the construction process between the base of steel columns and the foundation, the present invention provides a grouting module between steel columns and the foundation, which aims to reduce the amount of labor, improve work efficiency, simplify operation, and ensure that the grouting width is controllable and highly accurate.

[0005] The solution adopted by this invention to solve its technical problem is: a grouting module between a steel column and a foundation, comprising a template adjustment assembly, a slider assembly, and an L-shaped outer frame. The template adjustment assembly includes a template and a telescopic adjustment mechanism. The two vertical sidewalls of the L-shaped outer frame are respectively provided with grooves, each groove containing a corresponding slider assembly. A return spring for resetting the slider assembly is installed at the far end of each groove. A locking pin for locking the slider assembly inside is installed at the top of each groove. The outer ends of the two vertical sidewalls of each L-shaped outer frame are respectively connected to 45-degree connecting seats. After the connecting seats of two L-shaped outer frames are matched and connected, they are fixed together by connecting bolts to form a rectangular structure. The telescopic adjustment mechanism connects each template to the corresponding slider assembly. The templates located within the rectangular structure are joined end-to-end to form a rectangular shape.

[0006] The telescopic adjustment mechanism includes a sealed box, a free end plate, and a fixed connecting rod. Bearing seats are provided in the middle and on both sides of the inner wall of the sealed box, and corresponding bearings are installed thereon. A drive sprocket is installed in the middle bearing seat, and driven sprockets are installed in the bearing seats on both sides. A chain is looped between the drive sprocket and the driven sprocket. A fixed connecting rod connects the sealed box and the free end plate. Outer bearing seats are installed on the free end plate, and the outer ends of the driven sprockets on both sides are respectively installed in their corresponding outer bearing seats. A motor is fixed in the middle of the outer shell of the sealed box, and the motor shaft is coaxial with the shaft of the drive sprocket. A through hole is provided on the slider body, and a threaded sleeve is fixedly fitted thereon. Each screw shaft is installed in its corresponding threaded sleeve.

[0007] Fixed links are installed at the top and bottom of the chains on both sides, and a pressure wheel is fitted at the root of each fixed link. Each pressure wheel is supported on the outside of the chain, so that each pressure wheel simultaneously presses the chain inward, keeping each part of the chain in a state of inward compression.

[0008] The inner cavity of any side wall of the L-shaped frame has a sandwich layer, and transverse sliding grooves are opened on both sides of the sandwich layer. The slider assembly includes at least one slider body, which can be matched and fitted into the corresponding sliding groove. The upper and lower parts of the slider body converge inward and the middle part protrudes outward. The converged part is fitted into the sandwich layer, and the protruding part is matched and fitted into the sliding groove.

[0009] The slider body has multiple cavities inside, each of which can be used to house the battery and controller circuit board. The controller starts each motor according to the input signal and controls the stopping time of each motor by detecting the torque limit value of each motor. The two L-shaped frames are connected by a serial data cable and a plug. The controller is located inside one of the L-shaped frames or in the cavity of the slider body. The control panel connected to the input end of the controller has four pairs of start and stop buttons, corresponding to the start and stop control of the four motors. The control panel is fixed to the side wall or top of the L-shaped frame, or is independent of the frame.

[0010] A fixed seat is set on a 45-degree connecting seat, and a rotating shaft is vertically fixed on the fixed seat. There is a rotating sleeve at the root of the connecting bolt. At the same time, side slots are set on the outside of two adjacent 45-degree connecting seats. The connecting bolt carrying the nut can enter into the side slot or turn out of it by rotating. When the connecting bolt carrying the nut is turned into the side slot, the nut is tightened to fix the connection.

[0011] A lubricating oil box is installed inside the sealed box. Its opening is located at the outer end of the sealed box and is covered. An oil seepage pipe is connected to the bottom of the lubricating oil box. The distal outlet of the oil seepage pipe is fixed above the contact position between the chain and any sprocket.

[0012] Positioning tools are installed between each template and the side wall at the base of the steel column. These positioning tools are either lining plates, membrane width positioners, or flipping positioners.

[0013] The beneficial effects of this invention are as follows: This invention uses two L-shaped external frames to surround the base of the steel column and place them on the upper side of the foundation platform. The two L-shaped external frames are fixed together with bolts or fasteners, and the rotation of each motor is controlled by a control panel to ensure that each template is in a connected state. This allows for rapid assembly between the base of the steel column and the concrete foundation to form a surrounding mold, enabling precise adjustment and accurate grouting. The operation is simple, the construction efficiency is high, the grouting width can be precisely controlled at any time, and it is suitable for grouting construction between square or round steel columns of different widths or diameters and the foundation.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Example 1: A kind of Figure 1 The grouting module shown is designed to address the problems of high labor intensity, low work efficiency, and difficulty in accurately controlling the grouting thickness in existing construction methods for steel columns and foundations. The device is mainly composed of structural parts such as template adjustment component 10, slider component 20, and L-shaped external frame 30.

[0027] Specifically, from Figure 1 It can be seen that the ends of the two L-shaped outer frames 30 are fixed to form a square or rectangular outer frame, and the four template adjustment components 10 and the corresponding slider components 20 are combined to form the four sides of the square or rectangle, while keeping each template 11 simultaneously located inside the square or rectangular outer frame. Figure 2 As can be seen, the four templates 11 combine to form a square or rectangular structure.

[0028] Each of the four template components 10 includes a template 11 and a telescopic adjustment mechanism, such as Figure 5 As shown. The implementation of the telescopic adjustment mechanism is not limited, and its purpose is to move the template 11 closer to or further away from the slider assembly 20. Figure 4 An optimal implementation scheme for a telescopic adjustment mechanism is provided, but other implementation schemes are also possible, not limited to this one.

[0029] Figure 4As can be seen, after the inner wall of the sealed box is locally thickened in the middle and on both sides, bearing seats are set in the thickened areas and corresponding bearings are installed. A drive sprocket 13 is installed in the middle bearing seat, and driven sprockets 14 are installed in the bearing seats on both sides. A chain 18 is looped between the drive sprocket 13 and the driven sprockets 14. At the same time, fixed connecting rods 16 are installed at the upper and lower parts of the chain on both sides, and a pressure wheel 17 is fitted at the root of each fixed connecting rod 16. Each pressure wheel 17 is supported on the outside of the chain, so that each pressure wheel 17 simultaneously presses the chain inward, so that each part of the chain is kept in an inward compressed state.

[0030] like Figure 5 As shown, a motor 25 is fixed in the middle of the outer shell of the sealed box 12, and the motor shaft is coaxial with the shaft of the drive sprocket 13. Thus, when the drive sprocket 13 is rotated, the driven sprockets 14 on both sides can be driven to rotate synchronously. Figure 4 Combination Figure 5 It can be seen that each fixed connecting rod 16 has a free end plate 22 fixed to its outer end. An outer bearing seat 23 is installed on each free end plate 22, and the outer end of each screw shaft 15 is installed in its corresponding outer bearing seat 23. When each driven sprocket 14 rotates, it can drive its corresponding screw shaft 15 to rotate synchronously.

[0031] like Figure 1 and Figure 3 As shown, slide grooves 31 are respectively opened on the two vertical side walls of the L-shaped outer frame 30, and a corresponding slider assembly 20 is fitted in each slide groove 31. At the same time, a return spring 32 for resetting the slider assembly 20 is fitted in the far end of each slide groove. Figure 1 and Figure 3 It can also be seen that each slide groove 31 has a locking pin 33 installed on top to lock the internal slider assembly 20.

[0032] like Figure 1 and Figure 2 As shown, 45-degree connecting seats 34 are connected to the outer ends of the two vertical side walls of each L-shaped outer frame 30. After the connecting seats 34 of the two L-shaped outer frames 30 are matched and mated, they are fixed together by connecting bolts 35. The resulting assembly is square or rectangular in shape.

[0033] The telescopic adjustment mechanism is connected between each template 11 and the corresponding slider assembly 20. Specifically, as shown... Figure 1 Combination Figure 4 The inner cavity of any side wall of the L-shaped outer frame 30 has a sandwich layer, and transverse grooves 31 are formed on both sides of the sandwich layer. The slider assembly 20 includes at least one slider body, which can be fitted into the corresponding groove 31. Figure 4The image shows that the upper and lower parts of the slider body converge inward, while the middle part protrudes outward. The converged part is fitted into the interlayer, and the protruding part is fitted into the groove 31.

[0034] from Figure 1 It can also be seen that there is a clearance hole 27 at the center of the slider body of the slider assembly 20. The purpose of this hole is to avoid the motor, so that the slider assembly will not obstruct the motor after the template adjustment assembly 10 moves outward. Furthermore, from... Figure 1 and Figure 4 As can be seen, the slider body has through holes and is fixedly fitted with threaded sleeves 21. Each screw shaft 15 is installed within its corresponding threaded sleeve 21. Because each sliding sleeve assembly is confined within its corresponding groove, each threaded sleeve 21 is in a relatively fixed position. Therefore, when each screw shaft 15 rotates, it can move outward or inward along the threaded sleeve, thereby driving the template adjustment assembly to move outward or inward as a whole.

[0035] Figure 2 As can be seen, the templates within the rectangular structure are joined end-to-end to form a rectangular shape. When each motor drives the corresponding template adjustment assembly to move outward or inward, it simultaneously moves each template outward or inward. When any template moves inward, it simultaneously presses the adjacent template to move laterally, thus causing the corresponding slider assembly of that adjacent template to move laterally as well. When any template moves outward, the slider assembly of the adjacent template is pushed back laterally by the return spring, thereby always ensuring that the templates are in a joined-end state.

[0036] Inside the assembled formwork, after grouting, the pressure of the concrete on each formwork is perpendicular to the formwork itself, thus the formwork experiences almost no lateral pressure. To ensure the stability of the assembled formwork, perforations are made on the upper side of each slide groove 31, and vertical threaded sleeves are fitted inside. Locking pins 33 are installed within each vertical threaded sleeve. After achieving the optimal expansion and contraction state of the assembled formwork through the above adjustments, the four locking pins 33 are tightened to fix each slider assembly into its corresponding slide groove.

[0037] Figure 4 As can be seen, the slider body has multiple internal cavities, each of which can be used to house the battery and controller circuit board. The controller starts each motor based on the input signal and controls the stopping time of each motor by detecting the torque limit value of each motor (limiting pads are installed between each template and the side of the steel column base to ensure the distance between each template and the side of the steel column base).

[0038] In this embodiment, the above-described scheme involves placing two L-shaped outer frames 30 around the base of the steel column and on the upper side of the foundation platform. The two L-shaped outer frames 30 are fixed together with bolts or fasteners. The control panel controls the rotation of each motor, ensuring that each template is in a connected end-to-end state. One method of spacing is to use standard-width pads between each template and the side wall of the steel column base to limit the pouring width. Another method is to control the four templates to fit against the side walls of the steel column base and then expand outwards synchronously; in this case, it is necessary to ensure that the outer frames are fixed. The two L-shaped outer frames are connected via a series data cable 28 and a plug 29. The controller is located inside one of the L-shaped outer frames or in the inner cavity of the slider body. The control panel connected to the controller input has four pairs of start / stop buttons, corresponding to the start / stop control of the four motors. The control panel is fixed to the side wall or top of the L-shaped outer frame, or independent of the outer frame. The battery is sealed and fixed in the inner cavity of the L-shaped outer frame or the slider body; alternatively, an external power supply can be used via a socket. For larger L-shaped scaffolding, multiple lifting rings 36 located around the upper perimeter of the scaffolding can be used for hoisting and assembly, followed by alignment using handles 24 located on the outer side of the free end plate 22. For smaller L-shaped scaffolding, assembly and movement can be performed directly using the handles 24. This solution enables rapid assembly between the steel column base and the concrete foundation, allowing for precise adjustment and accurate grouting construction around the mold. It is simple to operate, highly efficient, and allows for precise control of the grouting width at any time. It is also suitable for grouting construction between square or round steel columns of different widths or diameters and the foundation.

[0039] Example 2: Based on Example 1, to further improve the connection efficiency of the two L-shaped frames, one end of the two L-shaped frames is hinged together by a pin, while the other end is connected by a movable fastener. For example... Figure 6 This diagram illustrates a movable fastening method where a fixing seat 37 is mounted on a 45-degree connecting seat, and a rotating shaft is vertically fixed to the fixing seat 37. A rotating sleeve 38 is located at the base of the connecting bolt 35. Side slots 39 are provided on the outer sides of two adjacent 45-degree connecting seats. The connecting bolt 35, carrying a nut, can be rotated into or out of the side slots 39. After the connecting bolt 35 with the nut is rotated into the side slot, the nut is tightened to secure the connection. This method allows for the rapid assembly and fixing of two L-shaped scaffolding units, and is particularly suitable for a series of pouring operations involving numerous steel columns and foundations.

[0040] Example 3: Based on Example 1, a lubricating oil box is further installed inside the sealing box 12. The opening of the lubricating oil box is located at the outer end of the sealing box and is covered. The bottom of the lubricating oil box is connected to an oil seepage pipe, and the far end outlet of the oil seepage pipe is fixed above the contact position between the chain and any sprocket.

[0041] Example 4: Based on Example 1, using as follows Figure 7 and Figure 8 The membrane width locator 40 shown replaces the pad and is used to quickly determine the standard distance between each template and the bottom of the steel column. As shown in the figure, the membrane width locator 40 includes two triangular plates 41, which are fixed together by a connecting rod 45. The inclined edge of the triangular plate 41 has markings 42, and a series of positioning holes 43 are evenly distributed on the inclined surface of the triangular plate 41. The inner root of the positioning holes 43 may have threads. When the positioning post 44 is fitted into different positioning holes, it can determine the depth of each triangular plate, thereby determining the distance between the template and the side of the steel column base.

[0042] In use, it is usually positioned directly between the template and the side of the steel column base, controlling the template to move outward until the positioning column falls and contacts the template surface. Another method is to fix a vertical plate on the outer shell of the sealing box, with a series of positioning holes distributed vertically on the plate. The positioning column 44 is inserted into the corresponding positioning hole to determine the original height of the triangular plate, thereby determining the distance between the template and the side of the steel column base, controlling each template to move inward until it is stopped by the membrane width positioning device 40 and cannot move further.

[0043] Figure 7 and Figure 8 As can be seen, a standard liner 46 (with the specified thickness) can be further installed on the right-angle side of the membrane width locator 40. Liners of different thicknesses can be replaced. The standard liner is temporarily assembled with the right-angle side via a plug 47 and a socket 48. The outer surface of the standard liner 46 can be flat or curved.

[0044] Example 5: Based on Example 1, using as follows Figure 9 and Figure 10 The flip-up locator 50 shown replaces the pad and is used to quickly determine the standard distance between each template and the bottom of the steel column.

[0045] Figure 10 In the flipping locator 50, a triangular plate 41 is included, with its hypotenuse facing outwards, one right-angled side facing inwards, and the other right-angled side facing upwards. A horizontal rotating sleeve 51 is fixed to the horizontal support rod 52 via a connecting plate 49. The horizontal rotating sleeve 51 is fitted onto the horizontal support rod 52, which is fixed to a fixing screw 54. The fixing screw 54 is fixed (welded or mounted on a support) to the outer shell of the sealing box, as shown below. Figure 9As shown. A support nut 55 is installed on the fixing screw 54, and a vertical rotating sleeve 53 is fitted on the upper part of the fixing screw 54. Adjusting the height of the support nut 55 can change the height of the vertical rotating sleeve 53, thereby changing the height of the triangular plate 41. The triangular plate 41 can be disengaged to the upper side of the grouting area by rotating the horizontal rotating sleeve 51, and can be moved out of the grouting area by rotating the vertical rotating sleeve 53. This embodiment is simple and convenient to operate, and can quickly determine the standard width between the template and the side of the steel column root. It is based on the simultaneous start of each motor to drive the corresponding template to move inward and automatically stop. The operation is simple and convenient to use.

[0046] Example 6: Based on Example 1, the sealing box 12 further includes an outer shell and a base plate, both of which are rectangular structures. The outer shell has flanges around its perimeter, and the outer shell is fixed to the base plate by the peripheral flanges and bolts. The outer shell is also fixed to the template by flanges and bolts.

[0047] Furthermore, based on Embodiment 1, a flexible protective cover, such as a ring-shaped or strip-shaped waterproof cloth, is fitted on the upper side between the combined outer frame of the grouting device and the template adjustment assembly.

[0048] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the present invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the present invention should be included within the protection scope of the present invention. For example, in Embodiment 1, the following... Figure 4 The telescopic adjustment mechanism shown can also be used by installing a telescopic component, such as an electric actuator, between the template 11 and the corresponding slider assembly 20, or by any other means to enable telescopic movement between the template 11 and the corresponding slider assembly 20. For example, the number of driven gears located within the template adjustment assembly 10 is not limited to two. It is not excluded to install pressure sensors on each screw shaft or screw sleeve to determine the template's limit movement state. For example, in Embodiment 1, when hoisting a large-volume L-shaped frame, it is not excluded to transfer and assemble the L-shaped frame by using a moving tool.
