Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of building material design, and particularly relates to a plastic steel plate and an assembled protection wall. Background Art
[0002] The construction difficulty and cost of a vertical roadbed constructed with cementitious fillers such as lightweight soil are greatly reduced because there is no need to use a high-strength retaining wall to withstand soil pressure. However, since the cementitious filler is fluid and needs to be left to solidify, although a high-strength retaining wall is not required, it is still necessary to build a protective wall with building materials such as plastic steel plates to enclose the cementitious filler. However, when using existing plastic steel plates to build a protective wall, the construction party often needs to use equipment such as nail guns to fix two adjacent plastic steel plates together, and each fixed plastic steel plate also needs to be nailed multiple times at multiple locations. The low installation efficiency leads to a long construction period of the protective wall, which seriously affects the progress of the project.
[0003] Therefore, the existing technology needs to be improved and developed. Utility Model Content
[0004] The purpose of the utility model is to provide a plastic steel plate and an assembled protection wall, which can be assembled into a protection wall without nailing or any equipment or tools, thereby greatly improving the construction period of the protection wall and helping to speed up the progress of the project.
[0005] In the first aspect, the utility model provides a plastic-steel plate used as a building material for a vertical roadbed with cementitious fillers, comprising a panel, a convex portion and a concave portion, wherein the convex portion and the concave portion are respectively arranged on opposite sides of the panel parallel to each other; the convex portion is used to be spliced with the concave portion of another piece of the plastic-steel plate; the concave portion is used to be spliced with the convex portion of another piece of the plastic-steel plate.
[0006] The plastic-steel plates provided by the utility model can be directly spliced through the concave parts and the convex parts, which greatly improves the installation efficiency of the plastic-steel plates, thereby significantly shortening the construction period of the protective wall and facilitating the acceleration of the project progress.
[0007] Furthermore, the convex portion and the concave portion extend in the same direction.
[0008] The convex and concave parts extending in the same direction make it easier to splice two plastic steel plates, which is beneficial to improving the splicing efficiency.
[0009] Furthermore, the convex portion and the concave portion both extend from one side of the panel to the other side opposite to the panel.
[0010] It can maximize the contact area when two plastic steel plates are spliced together, ensuring that the two plastic steel plates are firmly spliced together, thereby ensuring the strength of the protective wall.
[0011] Furthermore, an extension length of the convex portion is the same as an extension length of the concave portion.
[0012] It is beneficial to piece together multiple plastic steel plates into a regular protective wall, thereby improving the aesthetics of the protective wall.
[0013] Furthermore, the cross-sectional shape of the convex portion is an "H" shape; and the cross-sectional shape of the concave portion is a "C" shape.
[0014] Furthermore, it also includes T-shaped brackets, each of which is fixedly connected to the panel and forms an "I"-shaped cross-section with the panel.
[0015] Furthermore, the T-shaped bracket extends in a straight line direction, and the extending direction of the T-shaped bracket is the same as the extending direction of the protrusion.
[0016] Furthermore, the T-shaped bracket extends from one side of the panel to the other side opposite to the panel.
[0017] Furthermore, it comprises a plurality of the T-shaped brackets, and the plurality of the T-shaped brackets are arranged at intervals on the same side of the panel.
[0018] In the second aspect, the utility model provides an assembled protective wall, which is used as a component of a vertical roadbed with cemented filler, including a plurality of the above-mentioned plastic steel plates, any one of which is spliced up and down with at least one other plastic steel plate, and is spliced front to back with at least one other plastic steel plate; two adjacent plastic steel plates are connected by inserting the convex part of one of the plastic steel plates into the concave part of the other plastic steel plate; any two plastic steel plates connected front to back are staggered in the up and down directions.
[0019] From the above, it can be seen that the plastic steel plate of the utility model has recesses and protrusions, so that adjacent plastic steel plates can be spliced with each other through the recesses and protrusions. The splicing process does not require the aid of any equipment or tools, and there is no need to nail the plastic steel plates. This not only effectively shortens the construction period of the protective wall and is conducive to speeding up the progress of the project, but also prevents the plastic steel plates from being damaged.
[0020] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the embodiments of the utility model. The purpose and other advantages of the utility model can be achieved and obtained by the structures specifically pointed out in the written description and the drawings.

[0037] Reference Figure 1 , Attachment Figure 2 and attached Figure 7 The utility model provides a plastic steel plate used as a building material for a vertical roadbed with cementing fillers, comprising a panel 100, a convex portion 200 and a concave portion 300, wherein the convex portion 200 and the concave portion 300 are respectively arranged on opposite sides of the panel 100 which are parallel to each other; the convex portion 200 is used for splicing with the concave portion 300 of another plastic steel plate; the concave portion 300 is used for splicing with the convex portion 200 of another plastic steel plate.
[0038] In the present embodiment, in actual application, since the shapes of the protrusion 200 and the recess 300 are adapted to each other, the user can complete the splicing of the two plastic-steel plates 500 by inserting the protrusion 200 of one of the plastic-steel plates 500 into the recess 300 of the other plastic-steel plate 500. The splicing process is convenient and there is no need to connect the two plastic-steel plates 500 together by nailing or other means that damages the plastic-steel plates 500. This is not only conducive to shortening the construction period of the protective wall and speeding up the progress of the project, but also can prevent the plastic-steel plates 500 from being damaged and ensure the strength and integrity of the plastic-steel plates 500.
[0039] Furthermore, the panel 100 includes an interlayer 110 , which may be made of a glass fiber material. The provision of the interlayer 110 can effectively improve the overall fracture resistance of the plastic-steel plate 500 .
[0040] In some embodiments, the convex portion 200 and the concave portion 300 extend in the same direction. The convex portion 200 and the concave portion 300 extending in the same direction are more convenient for splicing two plastic-steel plates 500, which is beneficial to improving the splicing efficiency.
[0041] In some embodiments, the protrusion 200 and the recess 300 both extend from one side of the panel 100 to the other side opposite the panel 100, that is, the protrusion 200 and the recess 300 serve as opposite sides of the panel 100, which can maximize the contact area when the two plastic-steel plates 500 are spliced, ensuring that the two plastic-steel plates 500 are firmly spliced, thereby ensuring the strength of the protective wall.
[0042] In some embodiments, the extension length of the protrusion 200 is the same as the extension length of the recess 300. For example, in a rectangular panel 100, since the extension lengths of the protrusion 200 and the recess 300 are the same, it is beneficial to assemble multiple plastic steel plates 500 into a regular protective wall, thereby improving the aesthetics of the protective wall.
[0043] In certain embodiments, referring to Figure 2 and attached Figure 7 The cross-sectional shape of the convex portion 200 is an "H" shape; the cross-sectional shape of the concave portion 300 is a "C" shape. The "H"-shaped and "C"-shaped structures only involve grooves, which have a simple structure and low processing difficulty, and can avoid excessively increasing the cost of the plastic-steel plate 500, thereby avoiding a substantial increase in the construction cost of the protective wall.
[0044] In certain embodiments, referring to Figure 1 and attached Figure 2 The plastic steel plate further includes a T-shaped bracket 400 , each T-shaped bracket 400 is fixedly connected to the panel 100 and forms an “I”-shaped cross-section with the panel 100 .
[0045] In this embodiment, the plastic steel plate 500 is spliced into a protective wall and used to enclose the adhesive filler. The adhesive filler itself has fluidity and will flow to the position of the T-shaped bracket 400. When the adhesive filler solidifies into a base layer, the T-shaped bracket 400 increases the contact area with the base layer. At the same time, the T-shaped bracket 400 is equivalent to being buckled on the base layer, thereby greatly improving the fixing force of the protective wall and ensuring that the protective wall is firmly fixed on the base layer.
[0046] In some embodiments, the T-shaped bracket 400 extends in a straight direction and the extension direction of the T-shaped bracket 400 is the same as the extension direction of the protrusion 200. The extension direction of the T-shaped bracket 400 is unified with the protrusion 200 and the recess 300, which is more conducive to the processing of the plastic-steel plate 500, avoiding excessively increasing the cost of the plastic-steel plate 500, thereby avoiding a significant increase in the construction cost of the protective wall.
[0047] In some embodiments, the T-shaped bracket 400 extends from one side of the panel 100 to the other side opposite the panel 100. The T-shaped bracket 400 extends across the entire panel 100 to further increase the contact area between the plastic-steel plate 500 and the base layer, thereby further strengthening the fixing force of the protective wall on the base layer, which is beneficial to prevent the plastic-steel plate 500 from accidentally falling off from the base layer.
[0048] In certain embodiments, referring to Figure 1 and attached Figure 2The plastic steel plate includes a plurality of T-shaped brackets 400, and the plurality of T-shaped brackets 400 are spaced apart on the same side of the panel 100. Adding a plurality of T-shaped brackets 400 can further increase the contact area between the plastic steel plate 500 and the base layer, thereby further strengthening the fixing force of the protective wall on the base layer, which is beneficial to preventing the plastic steel plate 500 from accidentally falling off from the base layer.
[0049] Reference Figure 4 , Attachment Figure 5 , Attachment Figure 6 and attached Figure 7 The utility model provides an assembled protective wall, which is used as a component of a vertical roadbed with cemented filler, including the plastic-steel plate 500 of the above-mentioned embodiment, any plastic-steel plate 500 is spliced up and down with at least one other plastic-steel plate 500, and is spliced front to back with at least one other plastic-steel plate 500; two adjacent plastic-steel plates 500 are connected by inserting the convex part 200 of one of the plastic-steel plates 500 into the concave part of the other plastic-steel plate 500; any two plastic-steel plates 500 connected front to back are displaced in the up and down direction (the dislocation distance is, for example, 50 cm).
[0050] The plastic-steel plates 500 are assembled through the concave-convex structure, which has low difficulty in assembly and disassembly, is convenient and quick to assemble and disassemble, and has high bonding strength, which is conducive to improving construction efficiency, shortening construction period, reducing construction difficulty and ensuring the quality of the protective wall after construction. At the same time, the structure of the convex part 200 and the concave part 300 is simple, which will not make the structure of the plastic-steel plate 500 too complicated, and is conducive to maintaining the low price of the plastic-steel plate 500, and therefore will not increase the construction cost too much.
[0051] Furthermore, the staggered splicing of the front and rear connected plastic-steel plates 500 in the up and down directions can improve the splicing tightness between the plastic-steel plates 500 and the overall stability of the protective wall (the principle is similar to that of wall building and will not be repeated here), and make the overall surface of the protective wall smoother and more beautiful.
[0052] In certain embodiments, referring to Figure 8 and attached Fig. 9 A fastener 600 is arranged between two adjacent plastic-steel plates 500 spliced front and back, and the fastener 600 includes an elastic pad 610 and a spring 620. The cross-sectional shapes of the elastic pad 610 and the spring 620 are both "C"-shaped. The first end of the elastic pad 610 is crimped onto the convex portion 200 of one of the plastic-steel plates 500 and the second end of the elastic pad 610 is crimped onto the concave portion 300 of the other plastic-steel plate 500. The first end of the spring 620 is fixedly connected to the first end of the elastic pad 610 and the second end of the spring 620 is fixedly connected to the second end of the elastic pad 610. The spring 620 is used to provide opposing elastic forces to the first and second ends of the elastic pad 610 so that the elastic pad 610 is clamped on the corresponding convex portion 200 and concave portion 300.
[0053] In this embodiment, due to the limitation of processing accuracy, the dimensional accuracy of the protrusion 200 and the recess 300 is inevitably in error. At the same time, in order to reduce the difficulty of splicing the plastic-steel plate 500, the protrusion 200 and the recess 300 are generally clearance-matched. Therefore, the two adjacent plastic-steel plates 500 spliced front and back are always loose due to a certain gap between the protrusion 200 and the recess 300, so that the protective wall formed by the splicing appears tilted (that is, not perpendicular to the ground), which ultimately leads to the situation that the base layer does not meet the specified verticality, does not meet the specified height, etc.
[0054] In this regard, in order to strengthen the fastening force and tightness between the plastic-steel plates 500, fasteners 600 are arranged at the splicing positions of two adjacent plastic-steel plates 500 (i.e., the convex part 200 and the concave part 300), and opposite pressure is applied to the splicing positions by the fasteners 600, thereby avoiding the loosening of the protective wall due to the gap between the convex part 200 and the concave part 300, thereby ensuring that the base layer meets the design requirements.
[0055] The spring leaf 620 is mainly used to provide opposite elastic force, thereby driving the elastic pad 610 to press the protrusion 200 and the recess 300 from opposite sides, and the elastic pad 610 can be made of elastic materials such as rubber and silicone. The elastic material has good deformation ability and can adaptively change its shape under the elastic force of the spring leaf 620. On the one hand, it is convenient for users to install the fastener 600, and on the other hand, it can enable the fastener 600 to be better clamped on the protrusion 200 and the recess 300.
[0056] In actual application, the user uses the first end and the second end of the elastic pad 610 as force points to pry the elastic pad 610 outward, thereby overcoming the elastic force of the spring 620 and smoothly clamping the fastener 600 on the protrusion 200 and the recessed portion 300; the user can set multiple fasteners 600 at intervals at the same splicing position as needed, thereby ensuring the fastening force and tightness of each position of the two adjacent plastic steel plates 500.
[0057] In some embodiments, the reed 620 may be disposed inside the elastic pad 610 or outside the elastic pad 610 .
[0058] It should be noted that the fastener 600 will not be taken out after being clamped on the plastic-steel plate 500, and eventually the fastener 600 will be buried by the adhesive material and serve as a part of the base layer.
