Description

Technical Field

[0001] The invention relates to a cement-stabilized gravel base template supporting tool and a supporting frame, and relates to the technical field of road construction tools. Background Art

[0002] In road construction, cement-stabilized gravel base, a semi-rigid pavement base, has been widely used on highways of all grades due to its significant advantages. It possesses excellent plate properties, effectively distributing pavement loads; its high strength and rapid initial strength growth quickly meet the requirements of road construction and use; and its excellent mechanical properties, good water stability, and moderate frost resistance ensure long-term stable use in diverse environmental conditions. However, during the construction of cement-stabilized gravel base, to meet the construction requirements for pavement compaction, flatness, and thickness, formwork tools must be installed on both sides to enhance the support and stability of the cement. However, most of the existing formwork support workpieces are simple formwork formwork or support frames that are rigidly spliced ​​and built together. When faced with a roadbed path with a bend, these formwork and support frames cannot be well adapted to the direction of the splicing, resulting in difficulty in smooth construction on special roadbed sections. Moreover, the rigid connection between the side support formwork is not tight enough, which easily leads to large gaps. This poor rigid connection tightness easily leads to slurry leakage. During the cement pouring process, slurry will leak from these gaps, which not only causes material waste, but also affects the forming quality and appearance of the road surface. Generally, fillers are needed to block the gaps, and it is inconvenient to remove the cement forming mold in the later stage, especially for some bends where the formwork tools are difficult to lift out, which increases the time and cost of construction.

[0003] At the same time, the installation flexibility of the existing formwork tool support structure is not high. It is difficult to quickly adjust the direction and installation according to the actual situation (topography, space) during the construction process. The low installation flexibility cannot provide sufficiently stable support for the cement-stabilized gravel base, which may affect the quality of road construction. The entire support structure and strength are poor. Therefore, it is necessary to propose improvements to the cement-stabilized gravel base formwork support tool and support frame. Summary of the Invention

[0004] The present invention provides a cement-stabilized gravel base template supporting tool and a supporting frame, which overcome the deficiencies described in the background art.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a cement-stabilized gravel base formwork support frame includes a cement baffle and a flexible connecting piece, and the flexible connecting piece is detachable between the two cement baffles to realize the flexible connection of the cement baffles; a connecting box is fixed on the rear side of the cement baffle, and side panels are slidably embedded on both sides of the connecting box, and the side panels are extended to support one side of the flexible connecting piece; the side panels of the two adjacent cement baffles are extended relative to each other and locked together, forming the two cement baffles into a whole while supporting one side of the flexible connecting piece; the rear side of the connecting box is movably connected to a support assembly, and is fixedly connected to the ground through the support assembly.

[0006] Based on the above technical solution, preferably, the flexible connecting piece is H-shaped, and embedded card slots are respectively opened on both sides of the flexible connecting piece. The cement baffles are adapted to be inserted into the embedded card slots and are locked and connected to each other.

[0007] Preferably, based on the above technical solution, the flexible connecting piece is provided with first connecting holes on both the front and rear sides of the embedded slot, and second connecting holes corresponding to the first connecting holes are provided on both sides of the flexible connecting piece, and are fastened by bolts or wires.

[0008] Based on the above technical solution, preferably, both left and right sides of the flexible connecting piece are provided with inclined transition surfaces, and the thickness of the inclined transition surfaces gradually decreases from the middle to both sides.

[0011] Based on the above technical solution, preferably, the support assembly includes a first universal ball head bearing installed in the middle of the rear side of the flexible connecting plate, the first universal ball head bearing is universally connected to a universal ball head shaft, and the other end of the universal ball head shaft is universally connected to a second universal ball head bearing, the second universal ball head bearing is integrally connected to a support plate, and the support plate is annularly arrayed with ground nails, and the support plate is tightly attached to the ground and fastened to the ground through ground nails in all directions.

[0012] Based on the above technical solution, preferably, the support plate is provided with a plurality of hollow openings, and a side connecting plate is integrally provided on one side of the support plate.

[0013] Based on the above technical solution, preferably, two support assemblies are provided, and elastic tension strips are locked and connected between the side connecting plates on opposite sides of the support assemblies.

[0014] A cement-stabilized gravel base formwork support tool comprises the cement-stabilized gravel base formwork support frame.

[0015] By adopting the above technical solution, the present invention has the following advantages compared with the existing technology:

[0016] The structure of the present invention is very simple and ingenious. A flexible connecting piece is tightly sleeved between two cement baffles, and the flexible connecting piece is made of rubber material. The setting of the flexible connecting piece can be used to block the cement on the inner side of the roadbed, and the cement baffle can use the characteristics of the rubber material of the flexible connecting piece to flexibly turn, thereby adapting to the distribution of different road path directions. In addition, embedded slots are provided on both sides of the flexible connecting piece to connect with the cement baffles.

[0018] At the same time, the cement baffle is universally connected with a support assembly on the rear side to flexibly lock it with the corresponding terrain. Its support plate can rotate in multiple directions so that it is suitable for uneven or narrow terrain positions, and the support plate is driven into the ground or the side raised slope from all directions through multiple annularly distributed ground nails. It is very flexible to use, and there are two support assemblies. A rubber tension strip is connected between the two support assemblies to maintain a certain force transmission relationship, so that when one of the support assemblies slips outward, it can be elastically pulled by the other support assembly, and the elastic force of the rubber tension strip can enhance the tightness of the contact surface between the ground nails and the ground, so that the ground nails of the two support assemblies driven into the ground are tightly pulled by the lateral elastic force, which is conducive to avoiding loosening and nailing.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] like Figure 1-7 As shown, a cement stabilized gravel base formwork support frame includes a cement baffle 2 and a flexible connecting piece 1. The flexible connecting piece 1 can be detached between the two cement baffles 2 to realize the flexible connection of the cement baffles 2. Specifically, the flexible connecting piece 1 is H-shaped, and an embedding slot 10 is respectively opened on both sides of the flexible connecting piece 1. The cement baffle 2 is adapted to be inserted into the embedding slot 10, so that the front, side and back sides of the cement baffle 2 can be fully and tightly attached to the inner side of the embedding slot 10 of the flexible connecting piece 1, so that they form a whole. At the same time, the generation of gaps can be avoided, which greatly improves the tightness of the formwork and prevents cement slurry leakage. Moreover, the flexible connecting piece 1 is made of rubber material, so the setting of the flexible connecting piece 1 can also be used to block the cement on the inner side of the roadbed, such as Figure 7 As shown, the cement baffle 2 can make flexible turns by utilizing the flexible properties of the rubber material of the flexible connecting piece 1, so that the cement baffle 2 can adapt to the distribution of different road path directions during construction, greatly improving the flexible support effect and leak-proof performance of the template;

[0030] In the above technical solution, the first connection holes 11 are opened on both the front and rear sides of the embedded card slot 10 of the flexible connection piece 1, and the second connection holes 21 corresponding to the first connection holes 11 are opened on both sides of the flexible connection piece 1, and they are locked by bolts or tied with steel wires so that they are not easy to separate, thereby realizing a detachable connection between the cement baffle 2 and the flexible connection piece 1. This detachable connection is relatively convenient in the early installation and later demoulding, and can be reused to reduce costs.

[0031] A further design is that Figure 3 As shown, the flexible connecting piece 1 is provided with an inclined transition surface 12 on both sides. The thickness of the inclined transition surface 12 gradually decreases from the middle to the sides. The inclined transition surface 12 can transition the right angles or thicknesses on both sides of the flexible connecting piece 1, avoiding the edges being right angles or having a certain thickness. After the cement is formed, it will not be stuck on the cement due to the right angles or thickness, which facilitates the subsequent separation work and improves the quality and appearance of the cement after forming to a certain extent, thereby improving the use effect.

[0032] That is to say, through the design of the above-mentioned flexible connecting piece 1, the two adjacent cement baffles 2 can form an integral structure, the tightness and leakage prevention effect between the two cement baffles 2 can be improved, the cement baffles 2 can have a good turning distribution effect, the appearance effect of cement molding can be improved, and the flexibility and disassembly convenience of the entire structure can be enhanced.

[0033] In this embodiment, a connection box 3 is fixed to the rear side of the cement baffle 2, and side panels 4 are slidably embedded on both sides of the connection box 3. A protrusion 41 is integrally provided on the outer edge of the side panel 4. The protrusion 41 is respectively provided with a side through hole 42, and the two adjacent side panels 4 are locked and connected by bolts or steel wires inserted through the side through holes 42. Bolt locking is mainly used for the two side through holes 42 distributed on straight roads, and steel wires can be used for the two side through holes 42 distributed on straight or curved roads. When in use, the side panels 4 can be telescopically moved, and they have multiple functions. First, as Figure 1 As shown, before the side plate 4 is extended, interference with the installation of the flexible connecting piece 1 and the cement baffle 2 can be avoided, thereby avoiding affecting the installation efficiency; secondly, as shown in FIG. Figure 5 As shown, the side plate 4 is extended so that it is located at the rear side of the flexible connecting piece 1. Since the flexible connecting piece 1 is made of rubber, it may be deformed when supporting the cement on the roadbed. The side plate 4 can provide auxiliary support to the rear side of the flexible connecting piece 1, thereby improving the supporting strength of the flexible connecting piece 1; thirdly, as shown Figure 5As shown, while the above-mentioned side panels 4 support the flexible connecting piece 1, when the side panels 4 of the two adjacent cement baffles 2 are extended relative to each other and connected by bolt locking or steel wire binding, the two cement baffles 2 can be formed into an integral structure, thereby improving the overall structural strength, and the force can be simultaneously distributed to the connected cement baffles 2, thereby improving the overall support strength and support effect.

[0034] In this embodiment, Figure 4 and Figure 6 As shown, the rear side of the connecting box 3 is movably connected to a support assembly 5, and is fixedly connected to the ground through the support assembly 5. The support assembly 5 includes a first universal ball bearing 51 installed in the middle of the rear side of the flexible connecting piece 1, and the first universal ball bearing 51 is universally connected to a universal ball shaft 52, and the other end of the universal ball shaft 52 is universally connected to a second universal ball bearing 532, and the second universal ball bearing 532 is integrally connected to a support plate 53. Therefore, the universal ball shaft 52 can be universally rotated at the first universal ball bearing 51 of the connecting box 3, and the support plate 53 can be universally rotated at the outer end of the universal ball shaft 52. The effect of this rotation can be adjusted very flexibly to match the actual different terrain roads or side raised slopes, so that the ground The nails 54 drive the support plate 53 into the corresponding ground or slope, which is more flexible and more applicable than the existing fixed support rods. Moreover, the ground nails 54 are distributed in a circular array of six, and the force of the universal ball head shaft 52 acts on the middle of the support plate 53, that is, between the six ground nails 54. These six ground nails 54 are driven into the ground from multiple directions to improve the support stability in all directions, especially for roads that require turning distribution, the flexible support assembly 5 is more suitable; at the same time, the support plate 53 is provided with three hollow openings 531, and a side connecting plate 55 is integrally provided on one side of the support plate 53. The hollow opening 531 is mainly to adapt to the raised stone protrusions on the ground, allowing them to be stuck in the hollow opening 531, which can reduce obstacles, improve applicability, and is beneficial to the support effect.

[0035] Further, such as Figure 6 As shown, there are two support components 5, and an elastic tensioning strip 6 is locked and connected between the side connecting plates 55 on the opposite sides of the support plates 53 of the two support components 5. The rubber tensioning strip 6 allows the two support components 5 to maintain a certain force transmission relationship, so that when one of the support components 5 slips outward, it can be elastically pulled by the other support component 5, and the elastic force of the rubber tensioning strip 6 can enhance the tightness of the contact surface between the ground nails 54 and the ground, so that each ground nail 54 of the two support components 5 driven into the ground is tightly pulled by the lateral elastic force, which is conducive to avoiding loosening and nailing.

[0036] A cement-stabilized gravel base formwork support tool comprises the above-mentioned cement-stabilized gravel base formwork support frame.

[0037] The structure of the present invention is simple and ingenious. When it is implemented, the two adjacent cement baffles 2 are inserted into the embedded slots 10 on both sides of the flexible connecting piece 1, and the steel wire is passed through the first connecting hole 11 and the second connecting hole 21 to be tied tightly, so that the two cement baffles 2 are tightly formed into one body to prevent leakage. Under the elastic deformation of the flexible connecting piece 1, the two cement baffles 2 at this time can be adjusted in any direction according to the construction requirements of the road curvature. Then, the universal ball head shaft rods 52 and the support plates 53 of the two support assemblies 5 are adjusted to the terrain position such as the ground or slope that needs to be fixed, and the six directions of the ground are adjusted. The nails 54 fasten the support plates 53, during which the rubber tension strips 6 of the two support plates 53 can be stretched straight, so that they have a force transmission relationship, and the ground nails 54 driven into the ground by the two support plates 53 are tightened by the lateral elastic force to prevent them from loosening and falling off. Then the side panels 4 on both sides of the connecting box 3 are pulled out, so that the side panels 4 are located on the rear side of the flexible connecting piece 1 for support, and the side panels 4 of the two adjacent cement baffles 2 are tied with steel wire to prevent them from being separated from the position of the flexible connecting piece 1, and the two cement baffles 2 are formed as a whole to bear the force, thereby enhancing the overall support effect and structural strength.

[0038] It should be noted that the present invention mainly improves the above-mentioned structure. Functions, components, and structures not mentioned herein can be implemented by using components and structures in the prior art that can achieve the corresponding functions. The present invention has been described in detail above through specific embodiments, but these do not constitute a limitation of the present invention.
