A form assembly apparatus for concrete retaining wall construction

Abstract

This invention relates to the field of template technology and discloses a template assembly device for concrete retaining wall construction. The device includes a mold composed of two shells, multiple vibrating components housed within the shells, a mold-opening component on one side of the shells, a mounting plate on the side of the shells furthest from the mold-opening component, and a power component on the mounting plate for driving the vibrating and mold-opening components. The vibrating components continuously vibrate, loosening the contact surface between the retaining wall and the mold. The power component drives the mold-opening component, causing the mutually repelling components to continuously impact the wing plates on both sides of the mold. Simultaneously, the air pressure generated by the vibrating components during operation is introduced into an air storage tank through a manifold, and a one-way valve is installed to continuously increase the air pressure inside the air storage tank, further improving demolding efficiency. This also avoids continuous hammering of the mold during demolding, preventing cracks on the retaining wall surface and internal damage during demolding, thus ensuring the overall structural strength and quality of the demolded retaining wall.

Description

Technical Field

[0001] This invention relates to the field of template technology, specifically to a template component device for concrete retaining wall construction. Background Technology

[0002] Concrete retaining walls, also known as reinforced concrete retaining walls, are an important type of earth and rock structure engineering. They are composite material structures made of concrete and steel bars, used to resist the pressure of soil and water, and to ensure the safety and stability of the engineering structure.

[0003] During the mixing process, air inevitably gets trapped into the concrete mixture due to the rotation of the mixing blades and the tumbling of the mixing drum. This air cannot be completely expelled during mixing and ends up in the mold along with the concrete, resulting in more pores inside the cured concrete and affecting its compressive strength. Therefore, it is necessary to manually insert the handheld part of the concrete vibrator into the concrete to remove the air. However, due to differences in the skill and experience of the operators, the effect of air removal inside the concrete is inconsistent, resulting in some areas not being vibrated sufficiently while others are over-vibrated, affecting the uniformity and quality of the concrete. Furthermore, because it is impossible to precisely control the amount of cement in concrete manually, the shrinkage of concrete increases under high temperature conditions, resulting in greater friction between the formwork and the concrete. This increases the difficulty of demolding the concrete retaining wall. Moreover, when demolding manually by tapping the mold, quality problems such as cracks, damage, and pitting may appear on the concrete surface, affecting the aesthetic appearance of the retaining wall. At the same time, the tapping process may also cause tiny cracks and damage inside the concrete, leading to a reduction in the overall structural strength of the retaining wall.

[0010] As a preferred embodiment of the template assembly device for concrete retaining wall construction according to the present invention, the device comprises: an installation groove disposed within the flange; a receiving groove disposed within the installation groove; an installation block disposed within the installation groove; a spring four disposed on the side of the installation block near the flange; the end of the spring four away from the installation block being connected to the bottom of the installation groove; a hinge groove disposed within the installation block; a hinge block disposed within the hinge groove; a mating portion disposed at one end of the hinge block; and connecting shafts disposed on both sides of the end of the hinge block away from the mating portion.

[0011] As a preferred embodiment of the template assembly device for concrete retaining wall construction according to the present invention, wherein: the lever disposed in the storage groove has one end of the lever near the mounting block hinged to the side of the mounting block near the spring four, and the other end of the lever away from the mounting block hinged to the inner wall of the storage groove.

[0012] As a preferred embodiment of the formwork assembly device for concrete retaining wall construction according to the present invention, wherein: an air storage tank is disposed in the flange, a through hole is disposed in the air storage tank, a one-way valve is disposed in the through hole, and a manifold is disposed at the end of the one-way valve away from the through hole, and the manifold is connected to several branch pipes.

[0013] As a preferred embodiment of the template assembly device for concrete retaining wall construction described in this invention, wherein: the guide cylinder and the piston form a pneumatic chamber, an air inlet is provided on the side wall of the guide cylinder, the air inlet is connected to the interior of the pneumatic chamber, and a one-way valve is provided at the air inlet.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By arraying vibration components inside the shell, the power components drive the top column to continuously impact the box, thereby causing the shell to vibrate as a whole and vibrate the concrete poured into the mold. This causes the solid particles in the concrete to rearrange, reducing voids and improving the uniformity, density and durability of the concrete, which in turn improves the quality of the cured concrete retaining wall. 2. The continuous vibration of the vibrating component loosens the contact surface between the retaining wall and the mold. The power component drives the mold opening component, causing the mutually exclusive components to continuously impact the wing plates on both sides of the mold. The driving block forces the driven block to apply a force that moves the wing plates on both sides of the mold away from each other, which is beneficial for the demolding of the retaining wall. At the same time, the air pressure generated by the vibrating component during operation is introduced into the air storage tank through the manifold, and a one-way valve is set up to continuously increase the air pressure inside the air storage tank, further improving the demolding efficiency. This also avoids the continuous knocking of the mold during the demolding process, avoiding cracks on the surface of the retaining wall and internal damage during the knocking demolding process, and ensuring the overall structural strength and quality of the retaining wall after demolding. 3. By using mutually exclusive components to create a gap at the upper ends of the two shells, the hinge block pops out. The contact part continuously impacts the mating part, causing the mounting block to drive the lever. The lever then applies force to the lower ends of the two shells, preventing the concrete density at the lower ends of the shells from being too high, which would cause the lower end of the retaining wall to be too tightly connected to the lower end of the mold and thus prevent normal demolding. This further improves the demolding efficiency. Attached Figure Description

Detailed Implementation

[0026] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. Numerous specific details are set forth in the following detailed description to provide a thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention may be practiced without requiring some of these specific details. The following description of embodiments is merely intended to provide a better understanding of the invention by illustrating examples of the invention. The invention is by no means limited to any specific configurations and algorithms presented below, but covers any modifications, substitutions, and improvements to elements, components, and algorithms without departing from the spirit of the invention. Well-known structures and techniques are not shown in the drawings and the following description in order to avoid unnecessarily obscuring the invention. Example

[0027] Reference Figure 1-4According to the first embodiment of the invention, a template assembly device for concrete retaining wall construction is provided. This template assembly device for concrete retaining wall construction includes a mold, which consists of two shells 1, a flange disposed on the edge of the shell 1, a wing plate 11 disposed on the edge of the flange, a slider fixedly installed at the lower end of the shell 1, guide rails disposed at both ends of the slider, the slider being slidably disposed on the guide rails, a plurality of vibrating components 2 disposed inside the shell 1, a mold opening component 3 disposed on one side of the shell 1, a mounting plate 12 disposed on the side of the shell 1 away from the mold opening component 3, and a power component 4 disposed on the mounting plate 12 for driving the vibrating components 2 and the mold opening component 3. The power component 4 includes a motor, which is configured as a bidirectional motor, a bevel gear 1 on the output shaft of the motor, a bearing 1 located at the four corners of the two housings 1 facing away from each other, an eccentric rod 41 on the bearing 1, and several eccentric portions 42 on the eccentric rod 41. Each eccentric portion 42 includes two mounting plates, an eccentric shaft 43 located between the two mounting plates, the eccentric shaft 43 being located at the eccentricity of the mounting plates, and bevel gears 2 located at both ends of the eccentric rod 41. The bevel gear 2 located at one end of the eccentric rod 41 meshes with the bevel gear 1.

[0028] The oscillation component 2 includes two housings 1 with oscillation grooves 13 arranged in an array on opposite sides, a box 21 disposed within the oscillation grooves 13, a guide cylinder 22 disposed in the middle area of ​​the bottom of the box 21, a top column 23 disposed within the guide cylinder 22, a piston 24 disposed within the guide cylinder 22, a spring 25 disposed at the end of the top column 23 away from the housing 1, the end of the spring 25 away from the top column 23 being connected to the piston 24, a guide plate 26 disposed at the end of the piston 24 away from the housing 1, a connecting rod 27 disposed on the side of the guide plate 26 away from the piston 24, the end of the connecting rod 27 away from the guide plate 26 being hinged to an eccentric shaft 43, and a guide rod fixedly mounted at the bottom of the box 21, the end of the guide rod away from the box 21 passing through the guide plate 26, and the guide plate 26 moving linearly along the guide rod to limit the movement of the piston 24.

[0029] During use, first close the two boxes 21, then connect the flanges on both sides of the two shells 1 with bolts, then place the steel frame inside the mold, and then pour the mixed concrete into the mold. At this time, the motor is started, and the bidirectional output shaft of the motor drives the first bevel gear, which drives the second bevel gear, causing the eccentric rod 41 to rotate. Then, the eccentric shaft 43 drives the connecting rod 27 to rotate around the eccentric rod 41 as the axis, causing the guide rod to move linearly back and forth along the guide rod. At this time, the piston 24 drives the spring 25 and the top column 23 to strike the box 21. Under the action of several vibration components 2, the shell 1 vibrates. At this time, the air in the concrete inside the mold will be gradually discharged under the action of the mold vibration, and the solid particles in the concrete will also be rearranged and mixed evenly with the cement under the action of vibration. Example

[0030] Reference Figure 1-6 This is the second embodiment of the present invention, which differs from the first embodiment in that: The mold opening component 3 includes a mounting base 1, a linkage rod 31 mounted on the mounting base 1, a bevel tooth 3 mounted on one end of the linkage rod 31, the bevel tooth 3 meshing with a bevel tooth 2 mounted on the other end of the eccentric rod 41, and a paddle 32 mounted on the end of the linkage rod 31 away from the bevel tooth 3.

[0031] The mold opening component 3 also includes a second mounting base, a swing rod 33 mounted on the second mounting base, a second spring 34 mounted on the swing rod 33 away from the second mounting base, the end of the second spring 34 away from the swing rod 33 being connected to the housing 1, a side rod 35 mounted on the swing rod 33 near the second spring 34, and a mutual exclusion assembly 5 mounted on the side rod 35 near the second spring 34. A support rod is hinged to the side of the housing 1 near the mold opening component 3. During concrete pouring, the support rod will connect to the end of the swing rod 33 near the second spring 34, so that the swing rod 33 does not contact the lever at this time, thereby controlling the mold opening component 3 not to work during pouring.

[0032] The mutual exclusion component 5 includes a striking block 51, a movable cavity disposed within the striking block 51, discharge holes disposed on both sides of the striking block 51 and communicating with the movable cavity, driven blocks 52 disposed on both sides of the movable cavity, the driven blocks 52 having an isosceles triangular structure, a front insertion hole disposed at one end of the striking block 51 and communicating with the movable cavity, a front cone 53 disposed within the front insertion hole, a contact portion 54 disposed at the end of the front cone 53 away from the striking block 51, a driving block 55 disposed at the end of the front cone 53 away from the contact portion 54, the driving block 55 having an isosceles trapezoidal structure, and a limiting rod disposed at the end of the driving block 55 away from the front cone 53, the limiting rod penetrating the striking block 51. Spring 3 56 is located outside the limit rod and is located in the movable cavity. The end of spring 3 56 away from the drive block 55 is connected to the hammer block 51. One end of the driven block 52 is hinged to the hammer block 51. A torsion spring 1 is provided at the hinge point between the driven block 52 and the hammer block 51. One end of the torsion spring 1 is connected to the driven block 52 and the other end is connected to the hammer block 51. Under the action of the torsion spring 1, the driven block 52 is normally located in the movable cavity. Under the action of spring 3 56, the contact part 54 of the front cone 53 extends out of the hammer block 51. When the contact part 54 is subjected to external force, the driven block 52 will extend out of the discharge hole under the push of the drive block 55.

[0033] During use, after the concrete inside the mold has solidified, the support rod and the swing rod 33 are separated, and then the vibration component 2 is driven by the power component 4 to loosen the contact surface between the shell 1 and the solidified retaining wall. At the same time, the swing rod 33 is in contact with the paddle 32 under the tension of the second spring 34. The second bevel tooth drives the third bevel tooth, which in turn drives the linkage rod 31. This causes the paddle 32 to rotate around the linkage rod 31 as the axis. At this time, the paddle 32 will drive the swing rod 33 to swing around the hinge point with the mounting base 2 as the axis and gradually move away from the housing 1. Then, when the paddle 32 has rotated half a cycle, the paddle 32 will separate from the swing rod 33, causing the swing rod 33 to quickly approach the housing 1 under the pull of the second spring 34. This process is repeated. At this time, the side rod 35 will move synchronously with the swing rod 33, causing the mutual exclusion component to continuously strike the wing plate 11. When the contact part 54 contacts the flange at the closure of the two housings 1, under the action of the impact force, the front cone 53 will retract towards one end of the striking block 51. At this time, the driving block 55 will push the driven block 52, forcing the driven block 52 to rotate around the hinge point between one end of it and the striking block 51, and finally extend out of the discharge hole, so that the driven block 52 applies a pushing force to the wing plate 11, so that the mutual repulsion assembly applies a mutually repulsive force to the two adjacent wing plates 11. At the same time, the spring three 56 will deform and compress. When the mutual repulsion assembly gradually moves away from the housing 1, the front cone 53, the driving block 55 and the driven block 52 will be reset under the action of the spring three 56 and the torsion spring one.

[0034] The remaining structure is the same as that in Example 1. Example

[0035] Reference Figure 1-9 This is the third embodiment of the present invention, which differs from the second embodiment in that: The mounting groove 14 is provided in the flange, the receiving groove 15 is provided in the mounting groove 14, the mounting block 141 is provided in the mounting groove 14, the spring 142 is provided on the side of the mounting block 141 near the flange, the end of the spring 142 away from the mounting block 141 is connected to the bottom of the mounting groove 14, the hinge groove is provided in the mounting block 141, the hinge block 143 is provided in the hinge groove, the mating part 144 is provided at one end of the hinge block 143, the connecting shafts are provided on both sides of the end of the hinge block 143 away from the mating part 144, the end of the connecting shaft away from the hinge block 143 is hinged to the mounting block 141, the outside of the connecting shaft is fitted with a torsion spring 2, one end of the torsion spring 2 is connected to the mounting block 141, and the other end of the torsion spring 2 is connected to the hinge block 143.

[0036] The lever 151 is installed in the storage slot 15. The end of the lever 151 near the mounting block 141 is hinged to the side of the mounting block 141 near the spring 142, and the end of the lever 151 away from the mounting block 141 is hinged to the inner wall of the storage slot 15.

[0037] The air storage tank 16 is located inside the flange. When the two shells 1 are closed, the two air storage tanks 16 form a demolding cavity. A through hole is located in the air storage tank 16. A one-way valve 161 is located in the through hole. A manifold 17 is located at the end of the one-way valve 161 away from the through hole. The manifold 17 is connected to several branch pipes 171. The guide cylinder 22 and the piston 24 form a pressure chamber. An air inlet is located on the side wall of the guide cylinder 22 and is connected to the inside of the pressure chamber. A one-way valve 221 is located at the air inlet. An air outlet is located on the side wall of the guide cylinder 22 and is connected to the inside of the pressure chamber. The end of the branch pipe 171 away from the one-way valve 161 is connected to the air outlet. The air storage tank 16 has a vent hole that runs through it. A plug is installed at the vent hole. When the concrete is not cured, the vent hole is in the open state. When the concrete is cured and demolding is required, the vent hole is closed by the plug.

[0038] During use, when the concrete has solidified and been demolded, the vent hole is sealed with a plug. Then, during the operation of the vibrating component 2, the piston 24 will cooperate with the guide cylinder 22. When the piston 24 moves closer to the guide cylinder 22, the gas inside the air pressure chamber will be transported to the air storage tank 16 through the through hole via the branch pipe 171 and the manifold 17, and finally through the one-way valve 161. When the piston 24 moves away from the guide cylinder 22, the external gas is introduced into the air pressure chamber through the one-way valve 221. When a gap is formed at the mold-closing point at the upper end of the two shells 1, the hinge block 143 will rotate under the action of the torsion spring 2, so that the mating part 144 of the two adjacent hinge blocks 143 contacts. Then, under the impact of the contact part 54, the mounting block 141 will retract into the flange, so that the spring 4 142 is compressed and deformed. Then, the mounting block 141 will drive the lever 151 to rotate around the hinge point between its end away from the mounting block 141 and the inner wall of the receiving groove 15, so that the lever 151 prys the mold-closing part at the lower end of the two shells 1 to separate. Then, through the gradual increase of the air pressure inside the demolding cavity composed of the two air storage grooves 16 and the prying of the lever 151, the two shells 1 are separated, so as to quickly demold the concrete retaining wall without damaging the concrete retaining wall structure.

[0039] The remaining structure is the same as that in Example 2.
