Description

Technical Field

[0001] This utility model relates to the technical field of building construction, specifically to a side formwork support device for concrete pavement. Background Technology

[0002] Concrete pavement side formwork is a mold used to shape and fix the two sides of the pavement during concrete pavement construction. It plays a key role in ensuring the size, shape and overall quality of the concrete pavement. It is mainly made of wood, which is easy to process and can be flexibly customized in size and shape according to different pavement design requirements. The cost is relatively low, but wood is prone to deformation after absorbing water.

[0003] Existing molds may not be able to be flexibly adjusted according to different road widths and can only be used for road construction of specific widths. When encountering construction requirements of different widths, different molds need to be replaced, which increases construction costs and time. Furthermore, wooden molds will lose their support strength due to the influence of temperature and moisture. When bearing the weight and lateral pressure of concrete, they are prone to deformation or collapse, affecting the smoothness and overall quality of the road surface. Utility Model Content

[0004] The purpose of this invention is to provide a concrete pavement side formwork support device to solve the above-mentioned defects caused by the prior art.

[0005] A concrete pavement side formwork support device includes an alloy support, a side formwork, side limiting arms, and connecting rods. The alloy support has positioning holes evenly spaced on both sides. A side formwork is installed on one side of the alloy support, and strip grooves are evenly spaced on the outer side of the side formwork. A clamping mechanism is installed on one side of the side formwork. Two sets of side formwork apply pressure to both sides of the concrete pavement through the clamping mechanism on their backs. A threaded rod applies lateral clamping force to the side formwork to counteract the expansion force of the concrete. A positioning mechanism is installed directly above the side formwork, limiting the top of the side formwork and the alloy support. The limiting range of the two sets of side limiting arms is adjusted according to the width of the concrete pavement.

[0006] Preferably, the clamping mechanism includes a side template, rubber pads, threaded rods, and bearings. Rubber pads are evenly spaced and fitted onto the back of the side template. The inner end of the rubber pads is connected to the outer side of the bearing. The inner end of the bearing is connected to the threaded rod. The outer side of the threaded rod is connected to an alloy support.

[0007] Preferably, the threaded rod is connected to one end of the rubber pad via a bearing connected to the tail end, and the threaded rod as a whole has a frustum-shaped structure.

[0008] Preferably, the positioning mechanism includes fastening holes, a first slot, a side limiting arm, a second slot, a connecting rod, a fastener, and an inner guide groove. The fastening holes are evenly spaced on the outer side of the connecting rod. Side limiting arms are provided on both sides of the connecting rod. The bottom end of the side limiting arm is provided with a first slot, and the bottom of the side limiting arm is provided with a second slot. The side limiting arm is positioned directly above the two sets of alloy supports. A fastener is connected through the top end of the side limiting arm, and the inner guide groove is provided on one side of the side limiting arm.

[0009] Preferably, the side limiting arm is connected to the top of the alloy support through a slot at the bottom.

[0010] Preferably, the side limiting arm is connected to the top of the side template through a fastener, and the top of the side template is arranged parallel to the second slot.

[0011] Preferably, the side limiting arm is connected to both sides of the connecting rod through an internal guide groove, and both the side limiting arm and the connecting rod are provided with fastening holes.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The alloy support is positioned to the ground by bolts at the vertical top. The design of the alloy support provides good support and ensures that the side formwork remains stable during construction. The design of the positioning hole and the side limit arm can be flexibly adjusted according to different concrete pavement widths, which is highly adaptable. The clamping mechanism applies lateral clamping force to the side formwork through the threaded rod, which can effectively counteract the expansion force of the concrete and ensure the smoothness of the pavement.

[0014] 2. The tie structure formed by the side limiting arm and the connecting rod can effectively transmit and disperse these lateral pressures, enhance the stability of the entire side formwork support system, and prevent the side formwork from deforming, displacing or tilting under the action of concrete pressure. The limiting range of the side limiting arm can be adjusted according to the width of the concrete pavement, and the connecting rod can also be adjusted accordingly. This flexibility allows the tie structure to adapt to the construction needs of concrete pavements of different widths. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 5 As shown, a concrete pavement side formwork support device includes an alloy support 1, a side formwork 2, side limiting arms 11, and a connecting rod 13. Positioning holes 3 are evenly spaced on both sides of the alloy support 1. A side formwork 2 is provided on one side of the alloy support 1. Strip grooves 7 are evenly spaced on the outer side of the side formwork 2. A pressing mechanism 6 is provided on one side of the side formwork 2. Two sets of side formwork 2 apply pressure to both sides of the concrete pavement through the pressing mechanism 6 on their backs. A threaded rod 5 applies a lateral pressing force to the side formwork 2 to counteract the expansion force of the concrete. A positioning mechanism 10 is provided directly above the side formwork 2. The positioning mechanism 10 limits the top of the side formwork 2 and the alloy support 1. The limiting range of the two sets of side limiting arms 11 is adjusted according to the width of the concrete pavement.

[0024] Among them, the threaded rod 5 can precisely control the magnitude of the lateral clamping force applied to the side formwork 2 by rotating it. Construction personnel can adjust the pressure by rotating the threaded rod 5 according to the actual expansion of the concrete and construction requirements, thereby accurately counteracting the expansion force of the concrete.

[0025] The clamping mechanism 6 includes a side template 2, a rubber pad 4, a threaded rod 5, and a bearing 16. The rubber pad 4 is evenly spaced on the back of the side template 2. The inner end of the rubber pad 4 is connected to the outer side of the bearing 16. The inner end of the bearing 16 is connected to the threaded rod 5. The outer side of the threaded rod 5 is connected to an alloy support 1. The threaded rod 5 is connected to one end of the rubber pad 4 through the bearing 16 connected at its tail end. The threaded rod 5 has an overall frustum-shaped structure.

[0026] Among them, the side formwork 2 is fitted with a rubber pad 4 on its back. When the lateral clamping force is applied by the threaded rod 5, the rubber pad 4 plays a buffering role. During the pouring and hardening process of concrete, expansion force will be generated. The rubber pad 4 can absorb and disperse part of the impact force, so as to prevent the side formwork 2 from being damaged by sudden and excessive pressure and extend the service life of the side formwork 2.

[0027] The positioning mechanism 10 includes fastening holes 8, slot 1 9, side limiting arms 11, slot 2 12, connecting rod 13, fastener 14, and inner guide groove 15. The fastening holes 8 are evenly spaced on the outer side of the connecting rod 13. Side limiting arms 11 are provided on both sides of the connecting rod 13. Slot 1 9 is provided at the bottom end of the side limiting arm 11, and slot 2 12 is provided below the side limiting arm 11. The side limiting arms 11 are positioned directly above the two sets of alloy supports 1. The top of the side limiting arm 11 is... A fastener 14 is provided through the side, and an inner guide groove 15 is provided on one side of the side limiting arm 11. The side limiting arm 11 is connected to the top of the alloy support 1 through a slot 9 at the bottom. The side limiting arm 11 is connected to the top of the side template 2 through the fastener 14 at the top. The top of the side template 2 is parallel to the slot 12. The side limiting arm 11 is connected to both sides of the connecting rod 13 through an inner guide groove 15. Both the side limiting arm 11 and the connecting rod 13 are provided with fastening holes 8.

[0028] The top of the side limiting arm 11 is connected to the top of the side template 2 by fastener 14. The fastener 14 passes through the fastening hole 8 to tightly connect the side limiting arm 11 and the side template 2 together, ensuring that the positional relationship between the two is stable. The inner guide groove 15 is opened on one side of the side limiting arm 11. The two sides of the connecting rod 13 are connected to the side limiting arm 11 through the inner guide groove 15. The spacing between the two sets of side limiting arms 11 is adjusted according to the width of the concrete ground.

[0029] In practical applications, this type of concrete pavement side formwork support device includes the following tasks:

[0030] Step 1: The bolts on both sides of the alloy support 1 are used in conjunction with expansion bolts to fix it to the roadbed, or it is positioned with the wall or vertical channel steel on one side through the positioning holes 3 opened at equal intervals on both sides. According to the width of the concrete road surface, the operator then pulls the side limiting arms 11 on both sides so that the inner guide groove 15 opened inside the side limiting arm 11 is connected to the two sides of the connecting rod 13. The distance between the two sets of side limiting arms 11 is adjusted, and then the bolts are inserted into the fastening holes 8 to position the side limiting arms 11 and the two sides of the connecting rod 13.

[0031] Step 2: The operator connects the bottom slot 9 of the side limiting arm 11 to the top of the alloy support 1, and then connects the alloy support 1 and the side limiting arm 11 with bolts. The second slot 12 opened at the bottom of the side limiting arm 11 is then positioned with the top of the side template 2. The side template 2 and the top of the side limiting arm 11 are connected by fasteners 14. The strip groove 7 makes the contact between the side template 2 and the concrete no longer a complete planar contact. The contact area between the side template 2 and the concrete is relatively reduced. When demolding, the adhesion between the concrete and the side template 2 will also be reduced accordingly, making it easier to separate the side template 2 from the concrete.

[0032] Step 3: When it is necessary to press the side template 2, apply rotational torque to the threaded rod 5 through an external driving device (such as a wrench or other tools) to make the threaded rod 5 rotate around its axis. Since the threaded rod 5 is connected to the alloy support 1 and the alloy support 1 is fixed, the thread on the threaded rod 5 cooperates with the corresponding structure inside the alloy support 1. When rotating, it will generate axial thrust or pull. According to the positions of the two sets of side templates 2 that have been adjusted, the position of the rubber pad 4 is adjusted accordingly.

[0033] Step 4: The rotation of the threaded rod 5 causes it to move axially toward the side template 2. Since the tail end of the threaded rod 5 is connected to the rubber pad 4 through the bearing 16, the axial movement of the threaded rod 5 will drive the rubber pad 4 to move together. The rubber pad 4 is then attached to the back of the side template 2, thereby pushing the side template 2 to move in the pressing direction. As the threaded rod 5 continues to rotate and move axially, the side template 2 is gradually pressed, realizing the pressing and fixing of the workpiece placed on the side template 2. During the concrete pouring process, the newly poured concrete is restricted between the two side templates 2 and cannot flow and spread freely to both sides.

[0034] Step 5: During the clamping process, the rubber pad 4 plays a buffering role. When the side template 2 is pushed by the threaded rod 5 and comes into contact with the workpiece and is subjected to pressure, the rubber pad 4 can absorb part of the impact force, preventing the side template 2 from being damaged due to the large pressure at one moment. At the same time, the elasticity of the rubber pad 4 can make the clamping force more evenly distributed on the side template 2. Meanwhile, during the construction of the concrete pavement, the concrete will generate a large lateral pressure on the side template 2. The tie structure formed by the equally spaced side limiting arms 11 and the connecting rod 13 can effectively transmit and disperse these lateral pressures. It can also fix the moisturizing film on the connecting rod 13 to moisturize the concrete pavement.

[0035] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
