DETAILED DESCRIPTION

[0025] In order to make the objects, 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 some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection 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.

[0026] The template and construction method for installing artistic signs in saline-alkali land will be described in detail below with reference to the accompanying drawings and embodiments.

[0027] Example 1 like Figures 1-5 As shown, this embodiment provides a template for installing an art sign in saline-alkali land, including a plastic partition plate 2 and a plastic side panel 1. The plastic partition plate 2 is arranged on the bottom surface. The plastic material has good salt-alkali corrosion resistance. It is arranged on the bottom surface to isolate the salt water on the bottom surface of the saline-alkali land from directly contacting the subsequently poured cement structure, thereby avoiding the erosion of the cement by the salt water; the plastic side panel 1 is snapped onto the side of the plastic partition plate 2. The snap-on method facilitates the rapid assembly and disassembly of the template, and adapts to the convenience requirements of on-site construction in saline-alkali land; the plastic side panel 1 surrounds the steel bars in the middle, and the steel bars serve as the skeleton structure of the template, which can enhance the overall deformation resistance of the template and prevent the template from expanding or bursting due to pressure when pouring cement; the plastic partition plate 2 and the plastic side panel 1 together constitute a casting template, and the two cooperate to form a closed casting space to ensure that the basic shape that meets the installation requirements of the art sign is formed after the cement is poured.

[0028] The lower edge of the plastic side panel 1 is provided with a clamping portion 11, and the four sides of the plastic partition plate 2 are provided with a clamping groove portion 21 that cooperates with the clamping portion 11. The cooperation between the clamping portion 11 and the clamping groove portion 21 realizes the detachable connection between the plastic side panel 1 and the plastic partition plate 2, which is convenient for adjusting the template size or replacing damaged parts on site; an arc-shaped sealing portion 111 is provided on the inner side of the clamping portion 11, and the arc-shaped sealing portion 111 is arranged obliquely upward, and the clamping groove portion 21 is provided with a matching arc-shaped clamping groove 211 obliquely above. The obliquely upward arc-shaped sealing portion 111 matches the obliquely upward arc-shaped clamping groove 211 structure. During installation, the arc-shaped sealing portion 111 can slide smoothly into the oblique direction of the arc-shaped clamping groove 211, reducing the difficulty of installation; a limiting portion 21 is provided on the top of the arc-shaped clamping groove 211 2. After installation, the arc-shaped sealing portion 111 is located in the arc-shaped card groove 211 below the limiting portion 212. The limiting portion 212 can limit the arc-shaped sealing portion 111 from escaping from the arc-shaped card groove 211 upward to ensure the stability of the connection; and the outer side surface of the arc-shaped sealing portion 111 fits with the inner side surface of the arc-shaped card groove 211, and a preliminary seal can be formed during the initial installation to prevent salt water from seeping into the connection between the plastic side panel 1 and the partition plate; when the cement solidifies and shrinks, the cement will pull the plastic side panel 1 to shrink inward, and at this time the arc-shaped sealing portion 111 will be further squeezed into the arc-shaped card groove 211, and the fitting surface will be tighter due to the squeezing, effectively forming a sealed space after pouring. Even if the cement shrinks, a good sealing effect can be maintained to prevent salt water from entering the interior of the template and destroying the cement structure.

[0029] The middle of the plastic partition plate 2 is provided with a plurality of fixing holes 23, and the reinforcing steel bars pass through the fixing holes 23 during installation. The fixing holes 23 can position the positions of the reinforcing steel bars, prevent the reinforcing steel bars from being displaced due to cement flow during pouring, and ensure the shape accuracy of the reinforcing steel bar framework. The plastic side plate 1 is provided with a plurality of connecting lugs, and the reinforcing steel bars pass through the connecting lugs in the horizontal and vertical directions during installation. The horizontal and vertical reinforcing steel bars stagger through the connecting lugs to form a meshed reinforcing 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 reinforcing steel bars are connected as a whole, and after the cement solidifies, the three are bonded into a stable structure. The plastic parts and the reinforcing steel bars jointly bear the load, improve the service life of the formwork, and adapt to the complex environmental conditions of saline-alkali soil.

[0030] In order to further increase the sealing of the connection by using soil pressure and reduce the infiltration of salt water, the outer side wall of the clamping part 11 is an arc surface that fits with the inner side surface of the arc-shaped clamping groove 211 during installation. The arc 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 surface 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 soil pressure into extrusion force on the clamping part 11. After the formwork is buried, the soil 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 closely 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.

[0031] Further, in order to provide sufficient deformation space for the extrusion plate 213 and provide sufficient extrusion force, the side surface of the extrusion plate 213 close to the outer side surface 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 surface of the extrusion plate 213 is inclined, and the outer side surface of the extrusion plate 213 gradually approaches the plastic side plate 1 from bottom to top. The inclined outer side surface enables the soil 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 surface 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 soil pressure, and ensure the durability of the extrusion effect.

[0032] In order to ensure a stable connection between the steel bar and the plastic partition plate 2 and to prevent the plastic partition plate 2 from cracking and being damaged when the steel bar shakes, a reinforcement ring 24 is provided around the fixing hole 23. The reinforcement ring 24 can increase the thickness and strength of the plastic partition plate 2 around the fixing hole 23 to prevent the edge of the fixing hole 23 from being worn or cracked when the steel bar shakes; a rubber gasket 25 is provided in the reinforcement ring 24, and the fixing hole 23 is configured to be constricted. The constricted structure can limit the rubber gasket 25 to prevent the rubber gasket 25 from falling off from the fixing hole 23; the rubber gasket 25 and the fixing hole 23 have an interference fit, and the interference fit makes the rubber gasket 25 tightly fit the inner wall of the fixing hole 23, thereby enhancing the sealing effect of the fixing hole 23; when installing, the steel bar passes through the rubber gasket 25, and the inner diameter of the rubber gasket 25 is adapted to the diameter of the steel bar. The elasticity of the rubber gasket 25 can buffer the impact force when the steel bar shakes, and at the same time fill the gap between the steel bar and the fixing hole 23 to prevent salt water from seeping through the gap, thereby preventing the steel bar from being corroded by salt water and reducing its strength.

[0033] In order to ensure that the plastic side panels 1 are tightly connected, a plug-in groove 12 is provided on one edge of the plastic side panel 1. The plug-in groove 12 is provided in the vertical direction. The vertical plug-in groove 12 facilitates the up and down plugging of the plastic side panels 1, thereby improving assembly efficiency. A sealing rod 13 is provided on the other side of the plastic side panel 1. When installing, the sealing rod 13 is inserted into the plug-in groove 12. The cooperation between the sealing rod 13 and the plug-in groove 12 realizes the connection between the plastic side panels 1, thereby preventing gaps from appearing between the side panels. The sealing rod 13 is provided on the outside. The side wall fits with the inner wall of the plug-in slot 12, and the fitting surface can form a seal to prevent salt water from seeping into the connection between the side panels; the plastic side panel 1 is provided with a side pressure plate on the outside of the plug-in slot 12, and the side pressure plate is against the sealing rod 13. The side pressure plate applies a force to the sealing rod 13 to move into the plug-in slot 12, so that the sealing rod 13 fits more closely with the inner wall of the plug-in slot 12, thereby enhancing the sealing effect and preventing the sealing rod 13 from falling off from the plug-in slot 12, thereby ensuring the stability of the connection between the plastic side panels 1.

[0034] Preferably, in order to make the connection between the steel bar and the plastic side plate 1 stable, and to ensure that the plastic side plate 1 does not separate after the cement is solidified, and at the same time the plastic side plate 1 connection is further strengthened, 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 bar; the vertical lug 22 is provided with an extension part 221, which increases the contact length of the vertical lug 22 with the steel bar, and improves 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, and the steel bar located at the outermost side of the plastic partition plate 2 is simultaneously threaded through the waist-shaped connecting hole 222 during installation, the waist-shaped connecting hole 222 has a certain length allowance, which can adapt to the shrinkage deformation of the steel bar during cement solidification, and prevent the steel bar from pulling and cracking 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, and interference with the vertical lug 22 is avoided; the horizontal lug is perpendicular to the vertical lug 22, and the horizontal lug and the vertical lug 22 form a vertical structure, which can fix the horizontal steel bar; the horizontal steel bar is arranged in the horizontal lug, and the horizontal steel bar and the steel bar in the vertical lug 22 are tied together, and after the horizontal steel bar and the longitudinal steel bar are tied, a more stable mesh structure is formed, the overall strength of the steel bar framework is enhanced, and at the same time the connection between the plastic side plate 1 and the steel bar is more compact, preventing the plastic side plate 1 from separating from the steel bar framework after the cement is solidified.

[0035] In order to make the top not easy to be infiltrated by salt water, and to further increase the connection sealing performance by using earth pressure, a separation 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 separation cover plate 3 is provided with a sealing clamping groove part 31, and a sealing ring 32 is arranged in the clamping groove part 21, which 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 separation cover plate 3; when the separation cover plate 3 is subjected to a downward force from top to bottom, such as earth pressure acting on the separation cover plate 3 during burial, the sealing clamping groove part 31 will extrude the sealing ring 32, the sealing ring 32 will deform due to extrusion, fill the gap between the sealing clamping groove part 31 and the top of the plastic side plate 1, and enhance the sealing effect of the top; a reinforcing connection ring 33 is arranged at the middle position of the separation cover plate 3, which can improve the structural strength of the separation cover plate 3, and prevent the separation cover plate 3 from deforming due to excessive earth pressure; a plurality of embedded screw rods 34 are arranged on the reinforcing connection ring 33, which are connected with the legs of the artistic sign during installation, and can fix the artistic sign on the formwork, ensuring the stability of the installation of the artistic sign.

[0036] Further, in order to facilitate the replacement of the artistic sign, and to achieve low-cost simple replacement, the sealing protective cover 4 is sleeved on the leg of the artistic sign, which can prevent the salt water from directly contacting the leg and avoid the damage of the leg due to corrosion; and covers the top of the embedded screw 34, which can prevent the salt water from corroding the embedded screw 34 and prolong the service life of the embedded screw 34; when replacing the artistic sign, only the sealing protective cover 4 is removed, and the connection between the embedded screw 34 and the 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.

[0037] The lower edge of the sealing protective cover 4 is provided with a locking portion 41, and the outer side of the reinforced connecting ring 33 is provided with a connecting column 35, which provides a connecting position for the locking portion 41; the connecting column 35 is sleeved with a sealing gasket 36, which has elasticity; the locking portion 41 and the connecting column 35 are connected by screws, which can realize the detachable fixation of the sealing protective cover 4 and facilitate replacement; the sealing gasket 36 is extruded between the locking portion 41 and the isolation cover plate 3, and deforms due to extrusion, fills the gap between the locking portion 41 and the isolation cover plate 3, enhances the sealing effect of the connecting portion, and prevents the salt water from penetrating from the connecting portion; at the same time, the sealing gasket 36 can also buffer the pressure during screw connection, preventing the locking portion 41 or the isolation cover plate 3 from being damaged due to excessive pressure.
