Description

Technical Field

[0001] The present application relates to the technical field of retaining wall construction, and in particular to a rapid construction device for a cast-in-place retaining wall. Background Art

[0002] In the construction of retaining walls, it is usually necessary to roll the steel structure at the location where the retaining wall is cast, and then hoist the formwork to both sides of the steel structure to form a box structure with an opening on the top. After the formwork is installed stably, concrete can be poured into the gap between the formworks, thereby forming a retaining wall after the concrete slab is formed.

[0003] Since the template is generally heavy, the existing method of installing the template generally requires the use of an external crane to lift the template and cooperate with manual positioning and fixing to install the template. When the site is small and the crane cannot be moved to the lifting position, the template cannot be continuously lifted, which seriously affects the installation efficiency of the template. Utility Model Content

[0004] The purpose of the utility model is to solve or at least alleviate the problem that in the existing method of hoisting the formwork by a crane, when the site is small and the crane cannot be moved to the hoisting position, the formwork cannot be hoisted continuously, which seriously affects the installation efficiency of the formwork.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A rapid construction device for a cast-in-place retaining wall comprises two parallel bottom plates, the upper surfaces of the two bottom plates are fixedly connected with brackets, the brackets are equipped with adjustment structures, a lifting device is installed between the tops of the two adjustment structures, the lifting device comprises a same crossbeam passing between the tops of the two adjustment structures, a plurality of mounting holes are provided at the bottom of the crossbeam, two symmetrical mounting holes are equipped with electric hoists for lifting templates through connecting pieces, and a driving component for driving the overall device to move along the length line of the retaining wall is installed at the bottom of the bottom plate.

[0007] By adopting the above technical solution, when in use, the user first moves the bottom plates on both sides of the beam to the ground on both sides of the retaining wall respectively, and then adjusts the height of the beam according to the height of the template to be hoisted, and then fixes it with the positioning bolt, and then hangs the hook of the electric hoist on the end of the template to hoist the template. When the template under the beam is hoisted and fixed, the user can start the motor to drive the driving gear to rotate. Since the driving gear is meshed with the driven gear, when the driving gear rotates, it can drive the driven gear to rotate, thereby driving the driving wheel to roll along the ground. After adjusting the position of the entire device, repeat the above steps for continuous hoisting work, and try to avoid the existing method of hoisting the template by crane. When the site is small and the crane cannot be moved to the hoisting position, the template cannot be continuously hoisted, which seriously affects the installation efficiency of the template.

[0008] Optionally, the adjustment structure includes an adjustment tube that vertically penetrates the horizontal section of the bracket and has its bottom end fixedly connected to the upper surface of the base plate, an adjustment rod is slidably connected in the inner cavity at the top end of the adjustment tube, and the end of the cross beam vertically penetrates the adjustment rod at one end outside the adjustment tube and is slidably connected to the adjustment rod.

[0009] By adopting the above technical solution, when in use, the user can slide the adjustment rod up and down according to the height of the template to be hoisted, and adjust the beam installed at the top of the adjustment rod to a suitable height, so as to facilitate the staff to hoist templates of different heights.

[0010] Optionally, a section of the adjusting rod located in the inner cavity of the adjusting tube has multiple groups of positioning grooves symmetrically opened on both sides, and positioning bolts threadedly connected to the side walls of the adjusting tube are passed through the side walls of the adjusting tube, and a section of the positioning bolt located inside the adjusting tube is inserted into the corresponding positioning groove inner cavity.

[0011] By adopting the above technical solution, after adjusting the crossbeam to a suitable height, the user can screw the positioning bolt into the inner cavity of the adjusting tube, so that the end of the positioning bolt is inserted into the inner cavity of the corresponding positioning groove, thereby achieving relative fixation of the adjusting rod and the adjusting tube.

[0012] The optional crossbeam is in a T-shaped structure, and the mounting holes are opened on the vertical section of the crossbeam, and the plurality of mounting holes are evenly distributed along the length direction of the crossbeam.

[0013] By adopting the above technical solution and setting the beam as a T-shaped structure, the bending resistance of the beam can be greatly improved, and deformation of the beam during hoisting of the formwork can be avoided as much as possible. A plurality of equidistantly distributed mounting holes are set to facilitate users to adjust the distance between the two electric hoists according to the thickness of the retaining wall.

[0014] Optionally, the connecting piece includes a U-shaped mounting seat welded on the upper surface of the electric hoist, and bolts threadedly connected to the U-shaped mounting seat are passed through the side walls on both sides of the U-shaped mounting seat, and the middle section of the bolt is passed through the inner cavity of the corresponding mounting hole.

[0015] By adopting the above technical solution, a U-shaped mounting seat and bolts are provided for installing and fixing the electric hoist, and a screw connection method is adopted, which not only ensures a stable installation, but also facilitates the user to adjust the position of the electric hoist.

[0016] Optionally, the drive assembly includes two groups of drive wheels rotatably connected at the bottom of one end of two base plates, a driven gear is fixedly connected between the two drive wheels in each group, a protective cover is fixedly connected to the base plate above the driven gear, a driving gear is rotatably connected to the bottom of the inner cavity of the protective cover and meshes with the driven gear, and a motor for driving the driving gear to rotate is fixedly connected to one side of the protective cover.

[0017] By adopting the above technical solution, when the entire device needs to be moved, the motor can be started to drive the driving gear to rotate. Since the driving gear is meshed with the driven gear, when the driving gear rotates, it can drive the driven gear to rotate, thereby driving the driving wheel to roll along the ground and adjusting the position of the entire device.

[0018] Optionally, the driving assembly further includes universal wheels rotatably connected to the bottoms of the other ends of the two base plates.

[0019] By adopting the above technical solution, a universal wheel is rotatably connected to the bottom of the other end of the base plate, so that the user can adjust the forward direction of the entire device by rotating the angle of the universal wheel, which is convenient for the user to use.

[0020] In summary, the beneficial effects of this application are as follows:

[0021] The present application coordinates the structures such as the base plate, the crossbeam, the mounting holes, the electric hoist and the driving wheel. When in use, the user can move the base plates at both ends of the crossbeam to the two sides of the retaining wall respectively, and then adjust the distance between the two electric hoists and the height of the electric hoists to lift the formwork on both sides of the retaining wall at the same time. When the formwork under the crossbeam is lifted and fixed, the position of the entire device is adjusted by the driving wheel to carry out continuous lifting work, thereby avoiding as much as possible the problem that the existing method cannot realize continuous lifting of the formwork when the construction site is narrow, which seriously affects the installation efficiency of the formwork.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-3 This application is described in further detail.

[0027] See also Figure 1-3 A cast-in-place retaining wall rapid construction device comprises two parallel bottom plates 1, the upper surfaces of the two bottom plates 1 are fixedly connected with brackets 2, the brackets 2 are in an inverted U-shaped structure, and both ends of the brackets 2 are fixedly connected to the upper surface of the bottom plates 1 to improve the stability of the bottom plate 1 support.

[0028] An adjustment structure is installed on the bracket 2, and a lifting device is installed between the tops of the two adjustment structures. During use, the user can adjust the height of the lifting device according to the height of the retaining wall to be cast, so as to facilitate the lifting of templates of different heights.

[0029] The hoisting equipment includes a same crossbeam 7 passing through the tops of two adjusting structures, and a plurality of mounting holes 8 are provided at the bottom of the crossbeam 7, wherein two symmetrical mounting holes 8 are both equipped with electric hoists 9 for hoisting the formwork through connectors. Before use, the user can select appropriate mounting holes 8 to install the electric hoists 9 according to the thickness of the retaining wall to be cast, so that the distance between the two electric hoists 9 is equal to the distance between the retaining walls to be cast. After the electric hoist 9 is hoisted to one end of the formwork, it is convenient for the staff to fix the formwork.

[0030] A driving assembly is installed at the bottom of the base plate 1 for driving the entire device to move along the length line of the retaining wall. When the templates on both sides of a section of the retaining wall are hoisted to suitable positions and fixed by two electric hoists 9 respectively, the driving assembly can be used to drive the entire device to move to another position along the length direction of the retaining wall, and then the above steps are repeated for installation, thereby achieving continuity in the installation of the templates and greatly improving the installation efficiency of the templates.

[0031] Reference Figure 1 The adjustment structure includes an adjustment tube 3 that vertically penetrates the horizontal section of the bracket 2 and is fixedly connected to the upper surface of the bottom plate 1 at its bottom end. An adjustment rod 4 is slidably connected to the inner cavity at the top of the adjustment tube 3. The end of the crossbeam 7 vertically penetrates the adjustment rod 4 at one end outside the adjustment tube 3 and is slidably connected to the adjustment rod 4. When in use, the user can slide the adjustment rod 4 up and down according to the height of the template to be hoisted, and adjust the crossbeam 7 installed at the top of the adjustment rod 4 to a suitable height, so that the staff can hoist templates of different heights.

[0032] Reference Figure 3 The adjusting rod 4 is located in the inner cavity of the adjusting tube 3, and a plurality of positioning grooves 5 are symmetrically provided on both sides of the adjusting rod 4. The side walls of the adjusting tube 3 are provided with positioning bolts 6 that are screwed to the side walls of the adjusting tube 3. The positioning bolts 6 are located in the inner cavity of the adjusting tube 3 and are inserted into the corresponding positioning grooves 5. When the crossbeam 7 is adjusted to a suitable height, the user can screw the positioning bolts 6 into the inner cavity of the adjusting tube 3, so that the ends of the positioning bolts 6 are inserted into the corresponding positioning grooves 5, thereby achieving relative fixation of the adjusting rod 4 and the adjusting tube 3.

[0033] Reference Figure 1 The crossbeam 7 is in a T-shaped structure, and the mounting holes 8 are provided on the vertical section of the crossbeam 7. The multiple mounting holes 8 are evenly distributed along the length direction of the crossbeam 7. Setting the crossbeam 7 in a T-shaped structure can greatly improve the bending resistance of the crossbeam 7, and try to avoid deformation of the crossbeam 7 when the formwork is hoisted. Setting multiple evenly distributed mounting holes 8 facilitates the user to adjust the spacing between the two electric hoists 9 according to the thickness of the retaining wall.

[0034] Reference Figure 3 The connecting piece includes a U-shaped mounting seat welded on the upper surface of the electric hoist 9, and bolts threadedly connected to the U-shaped mounting seat are penetrated on the side walls of the U-shaped mounting seat, and the middle section of the bolt is penetrated in the inner cavity of the corresponding mounting hole 8. The U-shaped mounting seat and the bolt are used to install and fix the electric hoist 9. The threaded connection method is adopted, which is not only stable in installation, but also convenient for users to adjust the position of the electric hoist 9.

[0035] Reference Figure 1 and Figure 2 The driving assembly includes two groups of driving wheels 11 rotatably connected at the bottom of one end of two bottom plates 1, a driven gear 12 is fixedly connected between the two driving wheels 11 in each group, a protective cover 13 is fixedly connected to the bottom plate 1 above the driven gear 12, a driving gear 14 meshing with the driven gear 12 at the bottom is rotatably connected in the inner cavity of the protective cover 13, and a motor 15 for driving the driving gear 14 to rotate is fixedly connected to one side of the protective cover 13. When the whole device needs to be moved, the motor 15 can be started to drive the driving gear 14 to rotate. Since the driving gear 14 is meshingly connected with the driven gear 12, when the driving gear 14 rotates, it can drive the driven gear 12 to rotate, thereby driving the driving wheel 11 to roll along the ground to adjust the position of the whole device.

[0036] Reference Figure 3 The driving assembly also includes universal wheels 10 that are rotatably connected to the bottom of the other ends of the two bottom plates 1. The universal wheels 10 are rotatably connected to the bottom of the other end of the bottom plate 1, so that the user can adjust the forward direction of the entire device by rotating the angle of the universal wheels 10, which is convenient for the user to use.

[0037] The implementation principle of the present application is as follows: when in use, the user first moves the bottom plates 1 on both sides of the beam 7 to the ground on both sides of the retaining wall respectively, and then adjusts the height of the beam 7 according to the height of the template to be hoisted, and then uses the positioning bolt 6 to fix it, and then hangs the hook of the electric hoist 9 on the end of the template to hoist the template. When the template under the beam 7 is hoisted and fixed, the user can start the motor 15 to drive the driving gear 14 to rotate. Since the driving gear 14 is meshed with the driven gear 12, when the driving gear 14 rotates, it can drive the driven gear 12 to rotate, thereby driving the driving wheel 11 to roll along the ground. After adjusting the position of the entire device, repeat the above steps to perform continuous hoisting work, and try to avoid the existing method of hoisting the template by crane. When the site is small and the crane cannot be moved to the hoisting position, it is impossible to achieve continuous hoisting of the template, which seriously affects the installation efficiency of the template.
