Description

Technical Field

[0001] This invention relates to road construction technology, and more particularly to an outdoor road steel formwork fixing device and its usage method. Background Technology

[0002] Currently, channel steel formwork is used for outdoor road hardening construction in building projects. However, during road construction, channel steel is not easy to reinforce during installation, which can easily lead to problems such as formwork displacement and bulging. Previously, steel nails were used for fixing, but this method is also prone to bulging and displacement during concrete pouring. Even small errors or deviations can affect the appearance quality of the road and the straightness of the concrete. Post-construction repairs are also troublesome, and used steel bars are difficult to recycle, requiring secondary cutting and processing, increasing labor costs and construction difficulty. This wastes both manpower and materials, and increases construction costs. Summary of the Invention

[0003] The technical problem to be solved by this invention is: how to achieve high-quality road construction.

[0004] The following technical solution:

[0005] An outdoor road steel formwork fixing device, comprising:

[0006] The steel formwork is provided in two sets, which are symmetrically distributed.

[0007] Support components are installed on the back of the steel formwork. An adjusting component is installed on the side of the support component away from the steel formwork. The adjusting component is used to adjust the distance between the two steel formworks.

[0008] The compacting component includes a fixed body and a movable body. The fixed body is fixed to the bottom of the steel template. A horizontally arranged connector is threaded on the back of the fixed body. An adjusting component is fitted on the connector. The bottom of the adjusting component is movably installed on the movable body. An adjusting nut is threaded on the connector on the back of the adjusting component. A roadbed base plate is slidably installed on the bottom of the movable body. The roadbed base plate is fixedly installed on the roadbed.

[0009] Anchors are fixedly installed on the roadbed substrate.

[0010] The lower pressure component vertically penetrates the end of the adjusting component away from the support component. The lower pressure component is threaded onto the anchor and vertically presses against the adjusting component to limit the height of the top of the steel formwork.

[0011] In a preferred embodiment, the adjusting component includes a plate body arranged vertically, and the plate body is provided with a through hole for installing a connector. A pin is provided at the bottom of the plate body, and a vertical groove is provided on the back of the movable body, with the vertical groove and the pin slidingly engaged.

[0012] In a preferred embodiment, the movable body is internally equipped with a locking structure. The locking structure includes a mounting hole located inside the movable body. The bottom of the mounting hole communicates with the top of the vertical slide groove. A locking pin is installed inside the mounting hole. The locking pin includes a locking head and a pressure bearing head. The locking head can freely penetrate the mounting hole and protrude from the top of the movable body. The pressure bearing head and the locking head are flexibly installed by a spring. The bottom of the fixed body is provided with a locking hole that can be fitted and installed to the top of the locking head.

[0013] In a preferred embodiment, a transmission gear and a locking body are installed inside the movable body. Both the locking body and the locking head are provided with teeth, which are used to mesh with the transmission gear. The locking head drives the locking body downward through the meshing of the teeth and the transmission gear to lock and fix the movable body and the roadbed base plate.

[0014] In a preferred embodiment, a resonant plate is installed inside the fixed body, and the resonant plate resonates when the movable body is locked.

[0015] In a preferred embodiment, the roadbed substrate is provided with positioning holes located outside the moving area of ​​the moving body, and anchoring steel bars are inserted into the positioning holes, with the bottom of the steel bars being pointed.

[0016] In a preferred embodiment, a slide bar is installed on the top of the roadbed substrate, and a groove adapted to the slide bar is installed on the bottom of the movable body;

[0017] A sealing gasket is installed on the bottom front of the movable body, which is used to seal the movable body during lateral movement relative to the roadbed base plate.

[0018] In a preferred embodiment, a dovetail guide bar is installed at the bottom of the steel template along its length, and a dovetail groove adapted to the dovetail guide bar is provided at the top of the fixing body.

[0019] A method for using an outdoor road steel formwork fixing device includes the following steps:

[0020] First, lay out the lines on the roadbed to mark the installation edge lines of the roadbed base plate. Install the roadbed base plate according to the installation edge lines and anchor it with steel bars with pointed bottoms.

[0021] Secondly, the movable body is installed laterally on the roadbed base plate after being adapted by the sliding strip and the sliding groove. The adjusting part is a double-headed threaded rod with an adjustment area in the middle and threaded sleeves at both ends. The threads at both ends of the double-headed threaded rod are opposite in direction. The pressing part vertically inserts the threaded sleeve at the end of the adjusting part away from the steel template. The lateral position of the steel template is initially fixed by adjusting the threads of the pressing part and installing it in the anchor. The steel template and the supporting side of the roadbed base plate are placed in the same vertical plane by adjusting the adjustment area through the threaded areas at both ends, thus determining the final lateral position. The top of the pressing part is equipped with an operating handle, which is adjusted to the design elevation to meet and limit the final elevation requirements of the steel template.

[0022] Next, a connector is threaded onto the back of the fixed body, a plate is fitted onto the connector, a pin at the bottom of the plate is inserted into a vertical groove, and an adjusting nut is threaded onto the connector to apply pressure to the plate.

[0023] Next, a release agent is sprayed on the front of the steel formwork fixing device, the concrete pavement base is laid and subjected to vibration treatment, and the adjusting nut is adjusted to the side closer to the steel formwork. The adjusting nut pressing plate is gradually brought closer to the fixing body. The pin at the bottom of the plate moves up along the vertical slide groove, acting on the bearing head of the locking pin, and gradually compressing the spring inside the locking pin. The top of the locking head abuts against the bottom of the fixing body. When the front of the movable body and the front of the fixing body are aligned, the locking head of the locking pin will enter the locking hole under the action of the spring. At the same time, the locking body is driven down through the transmission gear to lock the movable body and the roadbed base plate. The locking head will act on the resonant plate to make a resonant action. At this time, the operating handle at the top of the pressing part and the top of the through end of the adjusting part are in contact.

[0024] Finally, when dismantling the device, remove the connecting parts. Under the action of the spring inside the locking pin, the plate moves downward, releasing the locking action of the locking head and locking body. The movable body is forced to move outward while the fixed body moves downward to complete the demolding, ensuring the straightness of the road surface side.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] This invention employs a laterally adjustable structure, utilizing adjustable components to laterally adjust the position of the steel formwork. This adapts to the pouring construction of roads of varying widths or irregular shapes, and allows for selection of a suitable installation location based on the foundation surface. A compaction structure is used; during pavement layer construction, the movable body compresses the pavement concrete, compacting the loose areas at the bottom. Due to the significant force exerted by the concrete on the movable body after compaction, and the relatively small restriction on the top of the plate near the movable body, a self-locking structure is designed to prevent displacement and formwork bulging under pressure. Simultaneously, the self-locking structure secures the fixed body, movable body, and roadbed base plate, making the entire device a unified whole. Furthermore, after the self-locking structure is formed, the resonant plate resonates, further compacting the roadbed on one side of the device. For dismantling, removing the connecting components completes demolding. Demolding is performed by the steel formwork descending, ensuring the straightness of the pavement side. If the steel formwork were used ascending, it would cause corner defects at the top edges of the pavement layer. Using the downward approach also involves regularizing the sides of the roadbed. Compared to the direct transverse removal method, this can prevent the side pavement layer from easily adhering to the side, causing defects and pitting. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0035] Example 1: An outdoor road steel formwork fixing device, such as... Figure 2 As shown, it includes:

[0036] Steel formwork 1, there are two sets of steel formwork 1, the two sets of steel formwork 1 are symmetrically distributed;

[0037] Support 2 is installed on the back of steel formwork 1. An adjusting component 3 is installed on the side of support 2 away from steel formwork 1. The adjusting component 3 is used to adjust the distance between the two steel formworks 1 and to adjust the position of the steel formwork 1 laterally to ensure that it is flush with the side of the subgrade base plate 446 during the later road construction and to jointly support the road surface layer.

[0038] like Figure 3As shown, the compacting component 4 includes a fixed body 41 and a movable body 42. The fixed body 41 is fixed to the bottom of the steel template 1. A horizontally arranged connector 43 is threaded onto the back of the fixed body 41. An adjusting component 44 is fitted onto the connector 43. The bottom of the adjusting component 44 is movably mounted on the movable body 42. An adjusting nut 445 is threaded onto the connector 43 located on the back of the adjusting component 44. A roadbed base plate 446 is slidably mounted on the bottom of the movable body 42. The roadbed base plate 446 is fixedly mounted on the roadbed. By adjusting the adjusting nut 445, the adjusting component 44 is pressed, causing the movable body 42 to move towards the road surface layer. The bottom of the fixed body 41 and the top of the movable body 42 are both sloping structures. By adjusting the adjusting nut 445 laterally, the position of the movable body 42 and the height of the steel template 1 can be adjusted.

[0039] like Figure 2 As shown, the anchor 5 is fixedly installed on the roadbed base plate 446. The anchor 5 is a vertically arranged threaded sleeve.

[0040] like Figure 2 As shown, the lower pressure member 6 vertically penetrates the end of the adjusting member 3 away from the supporting member 2. The lower pressure member 6 is threaded onto the internal thread of the anchor 5. The lower pressure member 6 vertically presses against the adjusting member 3 to limit the height of the top of the steel template 1.

[0041] like Figure 3 As shown, the adjusting component 44 includes a plate 441, which is vertically arranged and has a through hole for installing the connector 43. A pin 442 is located at the bottom of the plate 441, and a vertical groove 422 is located on the back of the movable body 42. The vertical groove 422 and the pin 442 are slidably engaged. When adjusting the movable body 42, the pin 442 moves upward along the vertical groove 422, ensuring that the movable body 42 is compacted into the road surface layer.

[0042] The roadbed base plate 446 is provided with positioning holes, which are located on the outside of the moving area of ​​the movable body 42. An anchoring steel bars are inserted into the positioning holes, and the bottom of the steel bars is set with a pointed tip.

[0043] A slide bar is installed on the top of the roadbed base plate 446, and a slide groove adapted to the slide bar is installed on the bottom of the movable body 42;

[0044] A sealing gasket is installed on the bottom front of the movable body 42. The sealing gasket is used to seal the movable body 42 during lateral movement relative to the roadbed plate 446.

[0045] The bottom of the steel formwork 1 is equipped with a dovetail guide bar along its length, and the top of the fixing body 41 is provided with a dovetail groove that matches the dovetail guide bar.

[0046] Example 2, based on the above examples, such as Figure 3 , Figure 4 , Figure 5 As shown, a locking structure is installed inside the movable body 42. The locking structure includes a mounting hole 421 inside the movable body 42. The bottom of the mounting hole 421 is connected to the top of the vertical slide groove 422. A locking pin is installed inside the mounting hole 421. The locking pin includes a locking head 423 and a pressure bearing head 424. The locking head 423 can freely pass through the mounting hole 421 and is exposed at the top of the movable body 42. The pressure bearing head 424 and the locking head 423 are flexibly installed by a spring. A locking hole is provided at the bottom of the fixed body 41. The locking hole can be adapted to the top of the locking head 423 for installation.

[0047] The movable body 42 houses a transmission gear 425 and a locking body 426. Both the locking body 426 and the locking head 423 are equipped with teeth that mesh with the transmission gear 425. The locking head 423, through this meshing, drives the locking body 426 downwards to lock and fix the movable body 42 and the roadbed base plate 446. The weight of the locking head 423 is sufficient to cause the locking body 426 to move upwards. When the locking head 423 disengages from the locking hole, gravity causes the locking head 423 and the pressure head 424 to move downwards, while the spring returns to its original position. At this point, the locking pin, transmission gear 425, and locking body 426 are in a balanced state, i.e., in equilibrium. Figure 5 The state shown.

[0048] Example 3, based on the above examples, such as Figure 3 and Figure 6 As shown, the fixed body 41 has a compartment inside that can accommodate a resonant plate 411, and the compartment is connected to the lock hole. The resonant plate 411 resonates when the movable body 42 is locked, and the resonant action further compacts the parts, especially at the junction of the movable body 42 and the fixed body 41. When the lock hole and the locking head 423 are matched, the spring will cause the locking head 423 to move upward and impact the resonant plate 411.

[0049] A method for using an outdoor road steel formwork fixing device includes the following steps:

[0050] First, lay out the installation edge line of the roadbed base plate 446 on the roadbed. Install the roadbed base plate 446 according to the installation edge line of the roadbed base plate 446 and anchor it with steel bars with the bottom pointed.

[0051] Secondly, the movable body 42 is installed laterally on the roadbed base plate 446 after being adapted by the sliding strip and the sliding groove. The adjusting part 3 is a double-headed threaded rod 31 with an adjustment area in the middle and threaded sleeves 32 at both ends. The threads at both ends of the double-headed threaded rod 31 are opposite. The pressing part 6 vertically inserts the threaded sleeve 32 at the end of the adjusting part 3 away from the steel template 1. The lateral position of the steel template 1 is initially fixed by adjusting the threaded installation of the pressing part 6 in the anchor 5. The steel template 1 and the supporting side of the roadbed base plate 446 are in the same vertical plane by adjusting the adjustment area through the threaded areas at both ends, thus determining the final lateral position. The top of the pressing part 6 is provided with an operating handle, which is adjusted to the design elevation to meet and limit the final elevation requirements of the steel template 1.

[0052] Furthermore, a connector 43 is threadedly installed on the back of the fixing body 41, and a plate 441 is fitted onto the connector 43. The pin 442 at the bottom of the plate 441 is inserted into the vertical sliding groove 422, and an adjusting nut 445 is threadedly installed on the connector 43. The plate 441 is pressed by the adjusting nut 445.

[0053] Next, a release agent is sprayed on the front of the steel formwork fixing device, the concrete pavement base is laid and subjected to vibration treatment, and the adjusting nut 445 is adjusted to the side closer to the steel formwork 1. The adjusting nut 445 is pressed against the plate 441 and gradually brought closer to the fixing body 41. The pin 442 at the bottom of the plate 441 moves upward along the vertical slide 422, acting on the pressure head 424 of the locking pin, and gradually compressing the spring inside the locking pin. The top of the locking head 423 abuts against the bottom of the fixing body 41. When the front of the movable body 42 and the front of the fixing body 41 are aligned, the locking head 423 of the locking pin will enter the locking hole under the action of the spring. At the same time, the transmission gear 425 drives the locking body 426 to move downward to lock the movable body 42 and the roadbed base plate 446. The locking head 423 will act on the resonant plate 411 to make a resonant action. At this time, the operating handle at the top of the pressing part 6 and the top of the through end of the adjusting part 3 are in contact.

[0054] Finally, when the device is to be dismantled, the connector 43 is removed. Under the action of the spring inside the locking pin, the pin 442 drives the plate 441 to move downward. The locking action of the locking head 423 and the locking body 426 is released. The movable body 42 is forced to move outward while the fixed body 41 moves downward to complete the demolding, ensuring the straightness of the side of the road surface layer.

[0055] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made to the technical solutions and inventive concepts of the present invention should all be covered within the scope of protection of the present invention.
