Description

Technical Field

[0001] The present invention relates to the technical field of casting and grouting construction, and particularly to an auxiliary device and construction method for grouting and casting of steel structure column feet. Background Art

[0002] Currently, during the grouting construction of steel structure column feet, the traditional method is as follows: ① Cleaning the foundation base to ensure that the surface of the grouting foundation is basically flat and has been roughened; ② Wetting the grouting contact surface, watering the grouting part within 24 hours before grouting, and sucking out the accumulated water 1 hour before grouting; ③ Erecting formwork, connecting the surrounding formwork into a whole with wooden squares and making it 10 cm larger than the perimeter of the original steel structure base. After the formwork erection is completed, tie the formwork to the whole steel column or column steel bars with wire; ④ Grouting with a chute, and vibration is strictly prohibited during the grouting process; ⑤ Curing, starting to cover and cure with plastic sheeting 2 - 5 hours after the grouting is completed, and the curing time is at least 14 days; ⑥ Removing the formwork and cleaning.

[0003] The existing construction has the following problems: First, the formwork erection process is cumbersome, the turnover rate of the formwork and wooden squares is relatively low, and the labor and material inputs during the construction process are large; Second, due to the strong fluidity of the grouting material, the formwork is prone to displacement during the pouring process, affecting the construction quality; Third, gaps are likely to appear at the joints between the formworks, and then leakage of grout will occur. It is necessary to plug the gaps again. During the plugging and reinforcement process, the inner surface of the formwork is likely to be uneven, affecting the pouring quality. Summary of the Invention

[0004] The present invention aims to solve the above problems, and thus provides an auxiliary device and construction method for grouting and casting of steel structure column feet that are convenient for construction, have a high turnover rate, and reduce construction costs.

[0005] The technical solution adopted by the invention to solve the above problems is:

[0006] An auxiliary device for grouting and casting of steel structure column feet includes a plurality of side formworks arranged around the base. The plurality of side formworks are connected end to end through connectors. A leak-proof rubber strip is provided at the joint between the side formworks. Each side formwork includes an inner plate and an outer plate. The inner plate and the outer plate are slidably connected and locked and fixed through a locking mechanism; a positioning protrusion is provided at the lower part of the inner plate, and the positioning protrusion is clamped on the upper edge of the base.

[0007] Further, an upper gear guide rail is provided on the outer side plate, and a lower gear guide rail is provided on the inner side plate. An insertion slot is provided between the rear half of the lower gear guide rail and the inner side plate. The outer side plate is slidably connected to the inner insertion plate through the insertion slot. An adjusting gear is meshingly connected between the upper gear guide rail and the lower gear guide rail, and an adjusting handle is connected to the adjusting gear. An outer shell is arranged outside the lower gear guide rail and the upper gear guide rail, and the end of the outer shell is fixed to the inner side plate. A long hole for rotating the adjusting handle is provided on the outer shell. By rotating the adjusting handle to rotate the adjusting gear, the relative position relationship between the inner side plate and the outer side plate can be adjusted, which is convenient for adjustment.

[0008] Further, the locking mechanism includes a base, a spring and a locking chuck. The base is fixed on the outer side plate. A vertically downward spring is connected to the base. The lower end of the spring is connected with a positioning chuck. Positioning teeth are provided on the lower edge of the positioning chuck. When the spring extends, the positioning teeth are meshed with the lower gear guide rail. When the spring shortens, the positioning teeth are separated from the lower gear guide rail. An adjusting hole for adjusting the position of the positioning chuck is provided on the outer shell; it is convenient to lock and fix from the outside.

[0009] Further, the connecting piece includes a hinge, a buckle, a fixing screw and a nut; there are four side templates. Three of the side templates are connected into a whole through hinges. Buckles are welded on both sides of the whole formed by connecting the three side templates. Fixing screws are welded on both sides of the other side template corresponding to the buckles; after the buckle is locked, the gap between the fixing ring of the buckle and the side template is larger than the diameter of the fixing screw and smaller than the diameter of the nut.

[0010] Further, U-shaped connecting grooves are provided along the upper edge and the lower edge of the inner side plate, and the outer side plate is slidably connected in the U-shaped connecting grooves; in order to make the inner side plate and the outer side plate closely fit during the sliding process, the U-shaped connecting grooves clamp the outer steel plate to prevent separation.

[0011] Further, it also includes an additional steel plate with the same thickness as the inner side plate. Hanging ears are provided along the upper edge of the additional steel plate. The additional steel plate is hung on the upper edge of the outer side plate through the hanging ears; the inner side plate and the outer side plate are installed with staggered joints, and there are high and low surfaces on the inner surface. By adding an additional steel plate, the inner surface of the whole side template is made flush.

[0012] Further, a rubber strip groove is also provided at the lower part of the inner side plate. A rubber strip is installed in the rubber strip groove. The rubber strip groove is located on the lower side of the positioning protrusion; the rubber strip on the lower side of the positioning protrusion fits with the concrete foundation, increasing the friction force and preventing the side template from moving during pouring.

[0013] Further, it also includes a horizontally arranged auxiliary slide rail. The left end of the auxiliary slide rail is fixedly connected to the inner side plate. An auxiliary groove is provided between the right part of the auxiliary slide rail and the inner side plate. The outer side plate is slidably installed in the auxiliary groove. An auxiliary block is slidably connected to the auxiliary slide rail, and the auxiliary block is fixedly connected to the outer side plate; it can guide the sliding direction of the inner side plate and the outer side plate, and ensure the stability of the inner side plate and the outer side plate during sliding.

[0014] The present invention also provides a construction method for grouting and pouring the steel structure column foot, which uses an auxiliary device for grouting and pouring the steel structure column foot for construction. The specific steps include:

[0015] S1: After cleaning and watering the surface of the foundation base to make it moist, connect three side templates into one body through hinges. Install vertical leak-proof rubber strips at the joints of the side templates. Adjust the included angle between the two leaves of the hinge to 90°. Adjust the length of each side template by sliding the inner plate and the outer plate so that the foundation base can slide into the opening formed by the three side templates. After the length adjustment is completed, lock and fix it through the locking mechanism.

[0016] S2: Slide the foundation base into the opening formed by the three side templates so that the positioning protrusions at the lower part of the side templates are stuck on the upper edge of the foundation base. Open the locking mechanism to adjust the connection length of the inner plate and the outer plate, contract the size of the side templates, so that the three side templates clamp the foundation base, and lock the locking mechanism.

[0017] S3: After adjusting the last side template to the appropriate size, paste leak-proof rubber strips on both sides of the last side template, and close the mold of the last side template and the three assembled side templates, and connect and lock them through connectors.

[0018] S4: Adjust the rectangular frame formed by the four side templates so that the rubber strips between the side templates are fixed and do not shake. Check the connection and locking conditions of each side template. After checking without errors, proceed to the next grouting process.

[0019] Furthermore, after each side template is adjusted to the size adapted to the foundation base and locked, attach additional steel plates to the inner side of the part where the outer plate extends beyond the inner plate.

[0020] The present invention adopting the above technical solution, compared with the prior art, its prominent features are:

[0021] This device can be reused during the construction of foundation bases with different sizes, has a high turnover rate. The side templates do not need to be tied to the whole steel column or column steel bars. The formwork support process is simple. The input of labor and materials during the construction process is small. During the pouring process, the formwork has high stability and will not displace, and the pouring quality is high.

[0041] The present invention will be further described below in conjunction with embodiments, and the purpose is only to better understand the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0042] As Figures 1 to 4 shown, the present invention provides an auxiliary device for grouting and pouring of a steel structure column foot, including four side formworks 2 arranged around the base of the foundation 1. The four side formworks 2 are connected end to end through connectors 3 to form a rectangular frame adapted to the base. At the four corners, an anti-leakage rubber strip 14 is provided at the joint of the side formworks 2. Each side formwork 2 includes an inner side plate 201 and an outer side plate 202. The inner side plate 201 and the outer side plate 202 are slidably connected and locked and fixed through a locking mechanism 9. A positioning protrusion is provided at the lower part of the inner side plate 201, and the positioning protrusion is clamped on the upper edge of the concrete foundation 1 of the base.

[0043] Furthermore, as Figures 11 to 13 , Figures 15 to 18 shown, the specific connection structure of the inner side plate 201 and the outer side plate 202 is that an upper gear guide rail 5 is provided on the outer side plate 202, and a lower gear guide rail 4 is provided on the inner side plate 201. An insertion groove is provided between the rear half of the lower gear guide rail 4 and the inner side plate 201, and the outer side plate 202 is slidably connected to the inner insertion plate through the insertion groove. An adjusting gear 6 is meshed and connected between the upper gear guide rail 5 and the lower gear guide rail 4, and an adjusting handle 7 is connected to the adjusting gear 6. The outer sides of the lower gear guide rail 4 and the upper gear guide rail 5 are clamped with an outer shell 8, and the left end of the outer shell 8 is fixed on the inner side plate 201 through a screw. A long strip hole 801 is provided on the outer shell 8. Through the long strip hole 801, the rotation of the adjusting handle 7 can be realized, and at the same time, the position of the adjusting gear 6 can be observed. Specifically, sliding grooves corresponding to the lower gear guide rail 4 and the upper gear guide rail 5 are provided on the inner side of the outer shell 8 up and down. During installation, the outer shell 8 slides from right to left to cover the lower gear guide rail 4 and the upper gear guide rail 5, and the left end is fixed on the inner side plate 201.

[0044] Furthermore, as Figure 17As shown, the locking mechanism 9 includes a base, a spring 902, and a locking chuck 901. The base is fixed on the outer plate 202. A vertically downward spring 902 is connected to the base. The lower end of the spring 902 is connected with a positioning chuck, and positioning teeth are provided on the lower edge of the positioning chuck. When the spring 902 extends, the positioning teeth catch the lower gear guide 4, and the adjusting gear 6 cannot rotate, locking the positions of the inner plate 201 and the outer plate 202. When the spring 902 contracts, the positioning teeth are separated from the lower gear guide 4, and the length of the side formwork 2 is adjustable. To facilitate the construction workers to operate the locking mechanism 9 from the outside, an adjustment hole 802 for adjusting the position of the positioning chuck is also provided on the housing 8.

[0045] Further, in order that the construction workers do not have to constantly push the locking chuck 901 by hand when adjusting the length of the side formwork 2, a locking projection is provided on the locking chuck 901, and a locking projection groove is provided on the housing 8. When the locking projection is lifted upward, the spring 902 contracts and the locking chuck 901 is separated from the lower gear guide 4. By snapping the locking projection into the locking projection groove, the locking chuck 901 can be always lifted upward. When it is necessary to lower the locking chuck 901 to lock the length of the side formwork 2, just pull the locking projection out of the locking projection groove.

[0046] Further, as Figure 1 , Figure 4 , Figure 9 , Figure 10 shown, the connecting member 3 includes a hinge 301, a buckle 304, a fixing screw 302, and a nut 303. Among them, the three side formworks 2 are connected into a whole through the hinge 301. The hinge 301 has two forms: opening and folding. When opening, the two side blades are in a 180° unfolded form, and when folding, the two side blades are in a 90° vertical form. Buckles 304 are welded on both sides of the whole formed by connecting the three side formworks 2. Each buckle 304 includes two buckle handles 3042 arranged at intervals up and down. A fixing ring 3041 is hinged on the lower buckle handle 3042, and a slot for clamping the fixing ring 3041 is provided on the upper buckle handle 3042. Fixing screws 302 are welded on both sides of another side formwork 2 corresponding to the buckles 304. After putting the fixing screw 302 between the two buckle handles 3042 and pulling the fixing ring 3041 up and locking it into the slot, a nut 303 is screwed on the fixing screw 302. The gap between the two buckle handles 3042, the fixing ring 3041, and the side formwork 2 is larger than the diameter of the fixing screw 302 and smaller than the diameter of the nut 303, so that after screwing on the nut 303, the last side formwork 2 is connected and fixed to the previous three side formworks 2.

[0047] Further, as Figure 12 , Figure 13 , on both the upper edge and the lower edge of the inner plate 201, U-shaped connecting grooves 13 are provided, and the outer plate 202 is slidably connected in the U-shaped connecting grooves 13. To enable the inner plate 201 and the outer plate 202 to fit tightly during the sliding process, the U-shaped connecting grooves 13 clamp the outer steel plate to prevent separation.

[0048] Furthermore, as shown in Figure 8 , it further includes an additional steel plate 203 with a thickness equal to that of the inner side plate 201. Hanging ears are arranged along the upper edge of the additional steel plate 203, and the additional steel plate 203 is hung on the upper edge of the outer side plate 202 through the hanging ears; the inner side plate 201 and the outer side plate 202 are installed with staggered joints, and there are high and low surfaces on the inner surface. Thus, by adding the additional steel plate 203, the inner surface of the entire side formwork 2 is made flush.

[0049] Furthermore, as shown in Figures 5 to 6 , a rubber strip groove is further provided at the lower part of the inner side plate 201, and a rubber strip is installed in the rubber strip groove. The rubber strip groove is located on the lower side of the positioning protrusion; the rubber strip on the lower side of the positioning protrusion fits with the concrete foundation 1, increasing the friction force and preventing the side formwork 2 from moving during pouring.

[0050] Furthermore, as shown in Figures 2 to 4 , it further includes a horizontally arranged auxiliary slide rail 10. The left end of the auxiliary slide rail 10 is fixedly connected to the inner side plate 201. There is an auxiliary groove between the right part of the auxiliary slide rail 10 and the inner side plate 201, and the outer side plate 202 is slidably installed in the auxiliary groove. An auxiliary block 1001 is slidably connected to the auxiliary slide rail 10, and the auxiliary block 1001 is fixedly connected to the outer side plate 202; it can guide the sliding direction of the inner side plate 201 and the outer side plate 202, ensuring the stability when the inner side plate 201 and the outer side plate 202 slide.

[0051] The present invention also provides a construction method for grouting and pouring the steel structure column foot. During specific construction, a steel structure column foot grouting and pouring auxiliary device needs to be used for construction. The construction steps include:

[0052] S1: As shown in Figure 7 and Figure 13 , after cleaning and watering the surface of the foundation 1 base, the three side formworks 2 are connected into one body through the hinge 301. A vertical leak-proof rubber strip 14 is added at the connection of the side formworks 2. The included angle between the two leaves of the hinge 301 is adjusted to 90°. By sliding the inner side plate 201 and the outer side plate 202, the length of each side formwork 2 is adjusted, so that the foundation 1 base can slide into the opening formed by the three side formworks 2 surrounding as a whole. After the length adjustment is completed, it is locked and fixed through the locking mechanism 9;

[0053] When adjusting the length of the side formwork 2, when the adjusting handle 7 is rotated clockwise, the adjusting gear 6 rotates clockwise and rolls to the right, and the inner steel plate and the outer steel plate move away from each other, and the side formwork 2 elongates; conversely, it shortens.

[0054] S2: As shown in Figure 6, slide the base 1 of the foundation into the opening formed by the three side templates 2 as a whole, so that the positioning protrusions at the lower part of the side templates 2 are stuck on the upper edge of the base 1 of the foundation; open the locking mechanism 9 to adjust the connection length between the inner plate 201 and the outer plate 202, shrink the size of the side templates 2, so that the three side templates 2 clamp the base 1 of the foundation, and lock the locking mechanism 9;

[0055] S3: As Figures 9 to 10 shown, after adjusting the last side template 2 to a suitable size, paste the leak-proof rubber strip 14 on both side edges of the last side template 2, and close the mold of the last side template 2 and the three assembled side templates 2, and connect and lock them through the connecting piece 3.

[0056] Furthermore, as Figure 8 , Figure 14 shown, after each side template 2 is adjusted to a size adapted to the base 1 of the foundation and locked, an additional steel plate 203 is hung on the inner side of the part where the outer plate 202 extends beyond the inner plate 201. There are hanging ears on the upper side of the additional steel plate 203, and the lower end of the additional steel plate 203 is flush with the upper edge of the positioning protrusion. At the same time, an I-shaped leak-proof rubber strip 14 is installed between the additional steel plate 203 and the inner plate 201..

[0057] S4: As Figure 1 shown, adjust the rectangular frame formed by the four side templates 2, and the rubber strip between the side templates 2 is fixed without shaking. Check the connection and locking conditions of each side template 2. After checking without errors, proceed to the next grouting process.

[0058] As Figure 6 , Figure 7 shown, this device can be reused during the construction of foundations 1 with different sizes, has a high turnover rate, the side templates 2 do not need to be tied to the bolts 11 or the steel structures 12, the formwork support process is simple, the labor and material inputs during the construction process are small, the formwork has high stability during the pouring process and will not displace, and the pouring quality is high.

[0059] The above are only the preferred and feasible embodiments of the present invention, and do not limit the scope of the rights of the present invention accordingly.
