Description

Technical Field

[0001] This application relates to the field of building construction, and in particular to a method for constructing exposed concrete walls. Background Technology

[0002] Exposed wall refers to a wall in construction projects where, after the wall is built, no additional decorative surface treatment such as plastering, tiling, or painting is required. Instead, the texture, color, and masonry pattern of the masonry material are directly preserved, showcasing a natural, simple, and primitive aesthetic effect.

[0003] In related technologies, to ensure the stability and airtightness of the wall, formwork is typically used to construct the wall's framework. These formworks are usually assembled using simple splicing and fixing methods. After the formwork is erected, concrete is poured into it, and the formwork is removed after the concrete has solidified. When dealing with details such as wall joints, temporary on-site splicing and filling methods are often used to ensure the wall's smoothness and aesthetics.

[0004] Regarding the aforementioned technologies, the inventors believe that during the construction process of the templates, the lack of precision in splicing adjacent templates can easily lead to uneven joints and misalignments on the wall surface, making subsequent repairs difficult. Summary of the Invention

[0005] To reduce the problem of uneven joints or misalignments in exposed concrete walls, this application provides a method for constructing exposed concrete walls.

[0006] This application provides a method for constructing a fair-faced concrete wall, employing the following technical solution: A method for constructing a fair-faced concrete wall includes the following steps: S1: Pour the bottom foundation; S2: Install the steel keel inside the fair-faced concrete wall on top of the bottom foundation; S3: Lay a leak-proof sealing layer on the bottom foundation surface; S4: Construct a molding template on top of the leak-proof sealing layer, including the following steps: S41. Multiple template units installed on the outside of the steel keel, each template unit including a first template corresponding to the outer wall surface and a second template corresponding to the inner wall surface, the first template and the second template being fixed by tie rods, the first template and the second template being arranged opposite to each other and forming a molding cavity for concrete pouring; S42. Two adjacent template units are spliced ​​together, and a third template for forming a boss is provided between two adjacent first templates. A forming groove is formed at the joint of the two adjacent first templates, which communicates with the forming chamber and is used for arranging the third template. The maximum thickness of the third template is less than the thickness of the forming groove. The third template has a demolding mechanism for separating the third template from the boss. S5: Pour concrete into the molding cavity so that the concrete fully fills the molding cavity and the molding groove; S6: Remove the template unit and operate the demolding mechanism to separate the third template from the outer wall surface; S7: Grind the protrusions on the exterior wall.

[0007] By adopting the above technical solution, in the construction process of fair-faced concrete wall, the bottom foundation is first poured in the construction area, a steel keel is erected on the top of the bottom foundation, and a leak-proof sealing layer is laid on the bottom foundation around the outer perimeter of the steel keel. Then, a forming template is built on top of the leak-proof sealing layer, and concrete is poured into the formed forming chamber and forming groove. After the concrete solidifies, the forming template is removed, and the third template is separated from the protrusion through a demolding mechanism. Finally, the protrusion on the outer wall surface of the fair-faced concrete wall is polished. This completes the entire process from construction to completion of the fair-faced concrete wall, effectively reducing the problem of uneven joints or misalignments in the fair-faced concrete wall.

[0008] Optionally, the first template includes a first substrate and a first liner disposed on the side of the first substrate facing the second template and adapted to the texture of the outer wall surface; the first substrate has a first through hole for arranging the tie rod, and the first liner has a first reserved hole opposite to the first through hole; the width of the first liner is smaller than the width of the first substrate, and the first substrate has a stepped structure formed on the outer edge of the first liner.

[0009] By adopting the above technical solution, a first liner mold adapted to the texture of the exterior wall is set to form the texture of the exterior wall. The first through hole and the first reserved hole facilitate the arrangement of tie rods. The stepped structure facilitates the docking of adjacent first templates to form a forming groove, which is beneficial to the subsequent forming of the boss.

[0010] Optionally, the step structure includes a first step surface and a second step surface symmetrically arranged on both sides of the first template; the first step surface and the second step surface of the adjacent first template are connected to form the forming groove.

[0011] By adopting the above technical solution, the specific structure of the stepped structure is further disclosed. Symmetrical first and second step surfaces are set on both sides of the first template, so that the first and second step surfaces of adjacent first templates can be connected to form a forming groove, which provides a basis for the subsequent arrangement of the third template and the forming of the boss, reduces the risk of misalignment at the joint of the fair-faced wall, and ensures the position and structural accuracy of the boss forming.

[0012] Optionally, the third template includes a support base and an elastic liner disposed on the support base for forming the raised surface of the fair-faced wall; the support base has a deformation chamber opening to a side away from the forming groove, and the elastic liner is disposed on the opening side of the deformation chamber; the outer edge of the elastic liner is provided with a sealing protrusion that abuts against the outer edge of the first liner in the circumferential direction.

[0013] By adopting the above technical solution, the elastic liner can better fit the forming of the exposed concrete wall protrusion, resulting in higher protrusion forming quality. The deformation chamber of the supporting base provides deformation space for the elastic liner. The sealing protrusion abuts against the first liner, which can reduce the risk of concrete leakage, ensure the forming accuracy of the protrusion, and improve the connection and sealing between the protrusion and the exposed concrete wall surface.

[0014] Optionally, the demolding mechanism includes two mounting side plates symmetrically arranged on both sides of the deformation chamber, and a support airbag arranged between the two mounting side plates for the elastic liner to abut against; the mounting side plates are provided with arrangement grooves along their length for arranging the support airbag; the support airbag has an air inlet pipe on the side facing the bottom of the deformation chamber, and the support base is provided with an arrangement through hole for arranging the air inlet pipe; the air inlet pipe has a limiting protrusion ring on the outside of the arrangement through hole.

[0015] By adopting the above technical solution, the elastic liner is supported by the cooperation of the mounting side plate and the supporting airbag, which facilitates the formation of the raised surface of the fair-faced wall by the elastic liner. The supporting airbag is inflated through the air inlet pipe. As the air enters, the internal air pressure of the supporting airbag increases and expands to the inside and outside of the deformation chamber, thereby pushing the elastic liner to bulge away from the deformation chamber, thus realizing the demolding of the third template from the raised surface. The limiting ring can reduce the risk of the air inlet pipe detaching from the arrangement through hole and entering the deformation chamber, which helps to ensure the stable operation of the demolding mechanism, thereby realizing the smooth separation of the third template from the outer wall surface.

[0016] Optionally, the mounting side plate has a snap-fit ​​protrusion extending along the length direction, and the support base has snap-fit ​​grooves on both side walls of the deformation chamber for arranging the snap-fit ​​protrusions of the two mounting side plates one by one; the snap-fit ​​protrusion has an arrangement hole on the side facing the bottom of the snap-fit ​​groove and a ball spring plunger is installed in the arrangement hole, and the bottom of the snap-fit ​​groove has a snap-fit ​​hole for arranging the plunger ball of the ball spring plunger.

[0017] By adopting the above technical solution, the snap-fit ​​protrusion of the mounting side plate cooperates with the snap-fit ​​groove of the support base, which facilitates the installation and positioning of the mounting side plate. At the same time, the ball-head spring plunger cooperates with the snap-fit ​​hole to achieve a stable connection of the mounting side plate on the support base, which facilitates the installation and disassembly of the demolding mechanism, improves construction efficiency and the reusability of the demolding mechanism.

[0018] Optionally, the support base has two limiting protrusions symmetrically arranged on the side facing the bottom of the forming groove. The two limiting protrusions extend along the length direction and are used to limit the two adjacent first templates one by one. The two first templates have guide grooves on the bottom side of the forming groove that correspond one by one to the two limiting protrusions.

[0019] By adopting the above technical solution, symmetrical limiting protrusions are set on the side of the support base facing the bottom of the forming groove. Together with the two guide grooves of the two adjacent first templates, they play a guiding role in the installation of the third template, making the installation of the adjacent first templates at the joint more accurate, which helps to reduce the risk of misalignment and improve the forming accuracy and construction quality of the fair-faced wall protrusions.

[0020] Optionally, the second template includes a second substrate and a second liner disposed on the side of the second substrate facing the first template; the second substrate has a second through hole that is directly opposite to the first through hole and is used for arranging the tie screw, and the second liner has a second reserved hole that is directly opposite to the second through hole.

[0021] By adopting the above technical solution, the second template can be better used in conjunction with the first template for fixing with tie rods. At the same time, the second through hole and the second reserved hole provide channels for the arrangement of tie rods, ensuring the accuracy and stability of template installation during construction, which is beneficial to subsequent concrete pouring operations.

[0022] Optionally, the first template is provided with a first sealing element at the first reserved hole for sealing installation of the tie rod, and the second template is provided with a second sealing element at the second reserved hole for sealing installation of the tie rod.

[0023] By adopting the above technical solution, a first sealing element and a second sealing element are respectively installed at the first reserved hole of the first template and the second reserved hole of the second template to seal the tie rod, which effectively reduces the risk of grout leakage from the connection between the tie rod and the template during concrete pouring.

[0024] In summary, this application includes at least one of the following beneficial technical effects: A method for constructing fair-faced concrete walls involves first pouring a bottom foundation in the construction area, then erecting a steel keel on top of the bottom foundation, and laying a leak-proof sealing layer on the bottom foundation around the outer perimeter of the steel keel. Next, a forming template is erected on top of the leak-proof sealing layer, and concrete is poured into the formed forming chamber and groove. After the concrete solidifies, the forming template is removed, and a demolding mechanism separates the third template from the protrusion. Finally, the protrusions on the outer surface of the fair-faced concrete wall are polished. This method realizes the entire process from construction to completion of the fair-faced concrete wall, effectively reducing the problem of uneven joints or misalignments in the fair-faced concrete wall. The use of elastic lining molds can better fit the forming of the exposed concrete wall protrusions, resulting in higher forming quality of the protrusions. The deformation chamber of the supporting base provides deformation space for the elastic lining molds. The sealing protrusion edge abuts against the first lining mold, which can reduce the risk of concrete leakage, ensure the forming accuracy of the protrusions, and improve the connection and sealing between the protrusions and the exposed concrete wall surface. The elastic liner is supported by the combination of the mounting side plate and the supporting air bladder, which facilitates the forming of the raised surface of the fair-faced wall. The supporting air bladder is inflated through the air inlet pipe. As the air enters, the internal air pressure of the supporting air bladder increases and expands to the inside and outside of the deformation chamber, thereby pushing the elastic liner to bulge away from the deformation chamber, thus realizing the demolding of the raised surface.

[0047] Reference Figures 1 to 8 A method for constructing a fair-faced concrete wall includes the following steps: S0: Measure and set out the area to be constructed; S1: Pour the bottom foundation 1 within the layout area; S2: Install the steel keel inside the exposed concrete wall body 2 on top of the bottom foundation 1; S3: Lay a leak-proof sealing layer 11 on the surface of the bottom foundation 1. The leak-proof sealing layer 11 is arranged around the steel keel to ensure the sealing of subsequent pouring. S4. Construct a molded template 3 on top of the leak-proof sealing layer 11, including the following steps: S41. Multiple template units 31 installed on the outside of the steel keel. Each template unit 31 includes a first template 311 corresponding to the outer wall surface 21 and a second template 312 corresponding to the inner wall surface 22. A release agent is applied to the first lining surface 421 and the second lining surface 422 of the first template 311 and the third lining surface 521 of the second template 312, respectively. The first lining mold 42 of the first template 311 and the second lining mold 52 of the second template 312 are arranged opposite to each other so that a forming chamber 33 for concrete pouring is formed between the first template 311 and the second template 312. The template unit 31 is fixed by tie rods 313, so that the first sealing element 3134 is arranged in the first reserved hole 423 and the second sealing element 3135 is arranged in the second reserved hole 522. The first nut 3132 and the second nut 3133 are tightened to lock the template unit 31. S42. Connect two adjacent template units 31 so that the first step surface 412 and the second step surface 413 of the two adjacent first templates 311 are opposite each other, and the first plane 4123 and the second plane 4133 are flush. The second side 4122 and the fourth side 4132 abut against each other to form a forming groove 414. Check the airtightness of the support airbag 62 and the surface integrity of the elastic liner 322. Then install the demolding mechanism 6 in the support base 321 and fill the support airbag 62 with a certain amount of gas so that the outer surface of the support airbag 62 abuts against the back side of the elastic liner 322. Insert the third template 32 for forming the boss 211 from the top of the forming groove 414. S43. Install a reinforcing back rib on the side of the first substrate 41 away from the first mold 42 and on the side of the second substrate 51 away from the second mold 52. S5: Concrete is poured into the molding chamber 33 so that the concrete fully fills the molding chamber 33 and the molding groove 414. Since the maximum thickness of the third template 32 is less than the thickness of the molding groove 414, a boss 211 can be formed at the molding groove 414 during the pouring process. During the pouring process, under the action of the concrete, the elastic liner 322 is recessed into the inside of the deformation chamber 3211, and the sealing protrusions 323 on both sides of the elastic liner 322 always abut against the second liner surface 422 to form a dynamic sealing structure of the molding groove 414, thereby making the boss 211 form a continuous arc surface 2111 and a connecting side surface 2112. S6: After the concrete has solidified, the reinforcing back ribs are removed, and then the formwork unit 31 is removed. At this time, the second lining surfaces 422 of the two first formworks 311 on both sides separate from the two connecting sides 2112 respectively, while the fourth lining surface 3221 of the third formwork 32 is attached to the arc surface 2111 of the boss 211. Air is injected into the supporting airbag 62 through the air inlet pipe 621, causing the elastic lining 322, which was originally concave inward, to expand in the direction away from the deformation chamber 3211, so that the fourth lining surface 3221 gradually separates from the arc surface 2111, thereby separating the third formwork 32 from the boss 211 and realizing the demolding of the third formwork 32 from the outer wall surface 21. S7: Grind the boss 211 to form a texture consistent with the outer wall surface 21, seal the tie bolt holes formed on the outer wall surface 21 and the inner wall surface 22 and repair local defects, clean the inner wall surface 22 and the outer wall surface 21 and apply a protective agent.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
