[0002] In a salt lake or saline-alkali land area, the soil contains a large amount of sodium chloride, which has a certain corrosive effect on building materials such as concrete and steel bars, resulting in damage to buildings.

DETAILED DESCRIPTION

[0036] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of the present application. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other in any manner without conflict.

[0037] The template for installing artistic signs in saline-alkali land and the construction method will be described in detail below with reference to the drawings and embodiments.

[0038] Embodiment one

[0039] As shown in the drawings, Figures 1-5 The present embodiment provides a template for installing artistic signs in saline-alkali land, which comprises a plastic partition plate 2 and a plastic side plate 1. The plastic partition plate 2 is arranged on the bottom surface and is made of plastic material with good salt and alkali corrosion resistance. The plastic partition plate 2 is arranged on the bottom surface to isolate the saline-alkali land bottom salt water from directly contacting the subsequent poured cement structure, so as to avoid the erosion of salt water to the cement. The plastic side plate 1 is clamped on the side edge of the plastic partition plate 2. The clamping mode is convenient for quick assembly and disassembly of the template and meets the convenience requirement of on-site construction in saline-alkali land. The plastic side plate 1 surrounds the steel bars in the middle part thereof. The steel bars serve as the framework structure of the template and can enhance the overall anti-deformation ability of the template, preventing the template from swelling or breaking due to pressure when pouring cement. The plastic partition plate 2 and the plastic side plate 1 jointly constitute a pouring template. The two plates cooperate to form a closed pouring space, so as to ensure that the cement poured forms a foundation shape meeting the installation requirement of artistic signs.

[0040] The lower edge of the plastic side plate 1 is provided with a clamping part 11, and the plastic partition plate 2 is provided with a clamping groove part 21 matched with the clamping part 11 on four sides. The cooperation of the clamping part 11 and the clamping groove part 21 realizes the detachable connection of the plastic side plate 1 and the plastic partition plate 2, which is convenient for adjusting the size of the formwork or replacing the damaged parts on site. The inner side of the clamping part 11 is provided with an arc-shaped sealing part 111, which is arranged obliquely upward. The clamping groove part 21 is provided with a matched arc-shaped clamping groove 211 obliquely upward. The arc-shaped sealing part 111 can be smoothly slid into the arc-shaped clamping groove 211 along the inclined direction of the arc-shaped clamping groove 211, which reduces the installation difficulty. The top of the arc-shaped clamping groove 211 is provided with a limiting part 212. After installation, the arc-shaped sealing part 111 is located in the arc-shaped clamping groove 211 below the limiting part 212. The limiting part 212 can limit the arc-shaped sealing part 111 from separating upward from the arc-shaped clamping groove 211, which ensures the stability of the connection. The outer side surface of the arc-shaped sealing part 111 is attached to the inner side surface of the arc-shaped clamping groove 211. When initially installed, a preliminary sealing can be formed to prevent salt water from penetrating from the connection between the plastic side plate 1 and the partition plate. When the cement solidifies and shrinks, the cement will pull the plastic side plate 1 inward. At this time, the arc-shaped sealing part 111 will be further pressed into the arc-shaped clamping groove 211. The fitting surface will be more tightly squeezed. After pouring, an effective sealing space is formed, which can maintain good sealing effect even if the cement shrinks, avoiding the entry of salt water into the formwork to damage the cement structure.

[0041] The middle part of the plastic partition plate 2 is provided with a plurality of fixing holes 23. During installation, the steel bars pass through the fixing holes 23. The fixing holes 23 can position the position of the steel bars to prevent the steel bars from shifting due to the flow of cement during the pouring process, ensuring the shape accuracy of the steel bar framework. The plastic side plate 1 is provided with a plurality of connecting lugs. During installation, the steel bars pass through the connecting lugs horizontally and vertically. The horizontal and vertical steel bars pass through the connecting lugs alternately to form a mesh steel bar framework, which further enhances the overall strength and anti-deformation ability of the formwork. After pouring, the plastic partition plate 2, the plastic side plate 1 and the steel bars are connected as a whole. After the cement solidifies, the three are bonded into a stable structure. The plastic parts and the steel bars jointly bear the load, which improves the service life of the formwork and adapts to the complex environmental conditions of saline-alkali land.

[0042] In order to further increase the sealing of the connection by using the earth pressure, reduce the infiltration of salt water, the outer wall of the clamping part 11 is arc-shaped, which is fitted with the inner side of the arc-shaped clamping groove 211 during installation. The arc-shaped surface can increase the contact area of the clamping part 11 and the arc-shaped clamping groove 211, and improve the initial sealing effect. The outer side of the clamping part 11 is provided with an extrusion part 112, which protrudes from the outer side of the plastic side plate 1. The outermost side of the clamping groove part 21 is provided with an extrusion plate 213, which abuts against the extrusion part 112 during installation. The abutting structure of the extrusion part 112 and the extrusion plate 213 can convert the earth pressure into extrusion force on the clamping part 11. After the formwork is buried, the earth pressure acts on the outer side of the plastic side plate 1, and the extrusion part 112 extrudes the extrusion plate 213, so that the clamping part 11 is more tightly fitted with the arc-shaped clamping groove 211, further enhancing the sealing of the connection and effectively preventing salt water from infiltrating from the connection.

[0043] Further, in order to provide sufficient deformation space for the extrusion plate 213 and provide sufficient extrusion force, the side of the extrusion plate 213 close to the outer side of the plastic side plate 1 is parallel to it. The parallel structure can ensure that the extrusion plate 213 is uniformly stressed and avoid local stress from being too large to cause damage. The outermost side of the extrusion plate 213 is inclined, and the outer side of the extrusion plate 213 gradually approaches the plastic side plate 1 from bottom to top. The inclined outer side enables the earth pressure to be more effectively transmitted to the extrusion part 112, increasing the extrusion force of the extrusion part 112 on the arc-shaped clamping groove 211. The outermost side of the extrusion plate 213 is provided with a plurality of reinforcing rib plates 2131, which are perpendicular to the outer side of the extrusion plate 213. The reinforcing rib plates 2131 can improve the structural strength of the extrusion plate 213, prevent the extrusion plate 213 from deforming or breaking due to excessive earth pressure, and ensure the durability of the extrusion effect.

[0044] In order to make the steel bar and the plastic partition plate 2 connect stably, and avoid the steel bar from shaking and causing the plastic partition plate 2 to crack and damage, the fixing hole 23 is provided with a reinforcing ring 24 around it. The reinforcing ring 24 can increase the thickness and strength of the plastic partition plate 2 around the fixing hole 23, preventing the steel bar from causing wear or cracking to the edge of the fixing hole 23 when it shakes. The reinforcing ring 24 is provided with a rubber gasket 25, and the fixing hole 23 is provided in a conical shape. The conical structure can limit the rubber gasket 25, preventing it from falling out of the fixing hole 23. The rubber gasket 25 is in interference fit with the fixing hole 23, which makes the rubber gasket 25 tightly fitted with the inner wall of the fixing hole 23, enhancing the sealing effect of the fixing hole 23. During installation, the steel bar passes through the rubber gasket 25, and the inner diameter of the rubber gasket 25 is matched with the diameter of the steel bar. The elasticity of the rubber gasket 25 can buffer the impact force when the steel bar shakes, fill the gap between the steel bar and the fixing hole 23, prevent salt water from infiltrating from the gap, and avoid the steel bar from being corroded by salt water and reducing its strength.

[0045] In order to ensure the tight connection between the plastic side plates 1, one side edge of the plastic side plate 1 is provided with a plug-in slot 12, which is arranged in the vertical direction. The vertical plug-in slot 12 facilitates the up-down plug-in between the plastic side plates 1, improving the assembly efficiency. The other side of the plastic side plate 1 is provided with a sealing rod 13, which is clamped into the plug-in slot 12 during installation. The cooperation between the sealing rod 13 and the plug-in slot 12 realizes the connection between the plastic side plates 1, preventing the gap between the side plates. The outer side wall of the sealing rod 13 is in close contact with the inner side wall of the plug-in slot 12, and the close contact surface can form a seal to prevent salt water from penetrating from the connection between the side plates. The plastic side plate 1 is provided with a side pressing plate outside the plug-in slot 12, which abuts against the sealing rod 13. The side pressing plate applies an acting force to the sealing rod 13 to move into the plug-in slot 12, so that the sealing rod 13 is more closely attached to the inner wall of the plug-in slot 12, enhancing the sealing effect and preventing the sealing rod 13 from falling off the plug-in slot 12, ensuring the stability of the connection between the plastic side plates 1.

[0046] Preferably, in order to make the connection between the steel bars and the plastic side plates 1 stable, and to ensure that the plastic side plates 1 will not be separated after the cement is solidified, and to further strengthen the connection of the plastic side plates 1, the connecting lug includes a vertical lug 22 and a horizontal lug. The vertical lug 22 is arranged along the height direction of the plastic side plate 1 and can fix the longitudinal steel bars. The vertical lug 22 is provided with an extension part 221, which increases the contact length of the vertical lug 22 with the steel bars, improving the stability of the connection. The end of the vertical lug 22 away from the plastic side plate 1 is provided with a waist-shaped connecting hole 222. During installation, the steel bars located at the outermost side of the plastic partition plate 2 pass through the waist-shaped connecting hole 222 at the same time. The waist-shaped connecting hole 222 has a certain length allowance, which can adapt to the shrinkage deformation of the steel bars during the solidification of the cement, preventing the steel bars from tearing the plastic side plate 1 due to shrinkage. The length of the horizontal lug is less than that of the vertical lug 22. The horizontal lug is arranged along the horizontal direction of the plastic side plate 1 to avoid interference with the vertical lug 22. The horizontal lug is perpendicular to the vertical lug 22, forming a vertical structure with the vertical lug 22, and can fix the horizontal steel bars. The horizontal lug is provided with a horizontal steel bar, which is tied and fixed together with the steel bars in one row of the vertical lug 22. After the horizontal steel bar is tied with the longitudinal steel bar, a more stable mesh structure is formed, enhancing the overall strength of the steel bar framework, and making the connection between the plastic side plate 1 and the steel bars more closely, preventing the plastic side plate 1 from being separated from the steel bar framework after the cement is solidified.

[0047] In order to make the top not easy to be infiltrated by salt water, and further increase the connection sealing by earth pressure, the isolation cover plate 3 is further included, which covers the top of the formwork and can prevent salt water from directly infiltrating the cement structure from the top of the formwork; the edge of the isolation cover plate 3 is provided with a sealing clamping groove part 31, and a sealing ring 32 is arranged in the sealing clamping groove part 31, and the sealing ring 32 has elasticity and can enhance the sealing effect; the sealing clamping groove part 31 is clamped with the top of the plastic side plate 1, and the clamping mode facilitates the installation and disassembly of the isolation cover plate 3; when the isolation cover plate 3 is subjected to a force from top to bottom, such as the earth pressure acting on the isolation cover plate 3 when buried, the sealing clamping groove part 31 will extrude the sealing ring 32, the sealing ring 32 is deformed due to extrusion, fills the gap between the sealing clamping groove part 31 and the top of the plastic side plate 1, and enhances the sealing effect of the top; the reinforced connecting ring 33 is arranged at the middle position of the isolation cover plate 3, which can improve the structural strength of the isolation cover plate 3 and prevent the isolation cover plate 3 from being deformed due to excessive earth pressure; a plurality of embedded screw rods 34 are arranged on the reinforced connecting ring 33, and the embedded screw rods 34 are connected with the supporting legs of the artistic sign during installation, so that the artistic sign can be fixed on the formwork and the stability of the installation of the artistic sign is ensured.

[0048] Further, in order to facilitate the replacement of the artistic sign and achieve low-cost and simple replacement, the sealing protective cover 4 is further included, which is sleeved on the supporting leg of the artistic sign and can prevent salt water from directly contacting the supporting leg and avoid damage of the supporting leg due to corrosion; and covers the top of the embedded screw rod 34, which can prevent salt water from corroding the embedded screw rod 34 and prolong the service life of the embedded screw rod 34; when replacing the artistic sign, only the sealing protective cover 4 needs to be removed, and the connection between the embedded screw rod 34 and the supporting leg is loosened, so that the new artistic sign can be replaced, which is simple to operate and does not need to damage the formwork structure, thereby reducing the replacement cost.

[0052] Embodiment Two

[0053] The application also provides a construction method for installing artistic signs in saline-alkali soil, comprising the following steps:

[0054] S01, a foundation pit is dug out in the saline-alkali soil, and drainage treatment is done. The saline-alkali soil contains a large amount of salt water. Digging the foundation pit can remove the surface saline-alkali soil to provide a clean construction space for the installation of the formwork.
