Description

Technical Field

[0001] This invention relates to the technical field of reinforcement devices for fair-faced sloping walls, specifically to a formwork reinforcement system and construction method for large-angle fair-faced sloping walls. Background Technology

[0002] Fair-faced concrete is a highly decorative type of concrete with wide applications within certain scopes. Due to the diversity of architectural styles, fair-faced concrete sloping walls are now appearing in many building structures, combining the decorative effect of fair-faced concrete with the unique shape of the sloping wall itself, giving the building structure a more distinctive character.

[0003] However, the installation and removal of formwork for multi-angled fair-faced concrete sloping walls present significant challenges. The support and reinforcement system must not only be able to adjust the formwork angle to ensure its installation in the designed position, but also guarantee the stability of the support so that the formwork can withstand the pressure and thrust of the wall. Since large-angle fair-faced concrete sloping walls generate substantial horizontal forces, designing reliable stress nodes to ensure the reinforcement system remains immobile is a key factor in guaranteeing the fair-faced concrete effect of the sloping wall.

[0004] Existing technology CN205476445U discloses a formwork reinforcement system for a large-angle fair-faced sloping wall, including: a back rib structure; a vertical guide rail installed on the fair-faced sloping wall formwork; a first transition crossbar installed on the vertical guide rail via a height limiting block; a second transition crossbar installed on the foundation surface via a limiting anchor; and a sloping wall frame, including frame diagonal bars, frame uprights, and frame crossbars; the top of the frame diagonal bar is connected to the first transition crossbar via a first U-shaped top support, and the bottom of the frame diagonal bar is connected to the second transition crossbar via a U-shaped bottom support; the bottom of the frame upright is fixed to the foundation surface, and the top of the frame upright is connected to the first transition crossbar via a second U-shaped top support. This patent document reflects a commonly used technology in fair-faced sloping wall reinforcement systems, but it has the following drawbacks: the support reinforcement system has a complex structure and cumbersome construction steps, which leads to a decrease in construction efficiency and an increase in labor intensity. Although the disassembly and assembly of the formwork itself is simplified, the disassembly and assembly of the support system itself is very troublesome.

[0005] Furthermore, due to inherent structural defects, its construction methods are inefficient, and its subsequent turnover and maintenance costs are high. Summary of the Invention

[0006] This invention provides a formwork reinforcement system and construction method for large-angle fair-faced sloping walls. This reinforcement system not only facilitates the assembly and disassembly of the formwork, but also makes the assembly, disassembly, and transportation of the reinforcement device itself convenient, thereby improving the reinforcement efficiency of fair-faced concrete sloping wall formwork and reducing labor intensity.

[0007] To solve the above problems, the technical solution of the present invention is as follows:

[0008] A formwork reinforcement system for a large-angle fair-faced sloping wall includes an inner formwork, an outer formwork, and a reinforcement device. The inner and outer formworks are connected by a tie mechanism. The reinforcement device is located on the inner side of the inner formwork. The reinforcement device includes a cubic support body. The top of the support body is provided with several first telescopic mechanisms, and the front end is provided with several second telescopic mechanisms. The tops of the first and second telescopic mechanisms are respectively provided with guide grooves and fasteners. Several transverse back ribs are evenly distributed on the outer surfaces of the inner and outer formworks. Several longitudinal back ribs are evenly distributed along the longitudinal direction on the back of the transverse back ribs. The guide rail is provided, and the guide rail slides in conjunction with the guide groove and is fixedly connected by fasteners. The bottom end of the guide groove is hinged to the top of the first telescopic mechanism or the second telescopic mechanism. An angle adjustment mechanism is connected between the guide groove and the first telescopic mechanism or the second telescopic mechanism. Several guide grooves correspond one-to-one with several guide rails. When several angle adjustment mechanisms adjust the guide grooves to a set angle, they position the inclination angle of the inner template. The front end face of the support body is parallel to the wall base marking line on the inner side of the fair-faced sloping wall. A locking plate is hinged to the bottom end of the guide rail, and the locking plate is fixedly connected to the ground by anchor bolts.

[0009] Preferably, both the inner and outer templates are assembled from one or more template bodies. The transverse back ribs are made of channel steel, and the bottom end of the flange of the channel steel is fixedly connected to the outer surface of the inner or outer template. Several tie bolt holes are evenly distributed on the top of the transverse back ribs. The tie mechanism fixes the inner and outer templates through the corresponding tie bolt holes. The guide rail is a C-shaped steel structure with the open end of the C-shaped steel structure facing outward. Several connecting holes are evenly distributed on the bottom of the C-shaped steel structure. A threaded hole is opened at the top of the transverse back rib opposite to the connecting hole. The guide rail is fixedly connected to the transverse back rib by bolts that pass through the connecting hole and are screwed into the threaded hole.

[0010] Preferably, the length of the support body is consistent with the width of the inner template. The guide groove includes a channel steel body. Guide plates are welded to the inner surfaces of the two side walls of the channel steel body, respectively, and are arranged along the top direction of the channel steel body. The two ends of the opening of the C-shaped steel structure are slidably engaged with the outer surfaces of the guide plates on the same side. The width of the two ends of the opening is smaller than the width of the guide plates. The outer surface of the C-shaped steel structure is slidably engaged with the inner surface of the side wall of the channel steel body on the same side. The fastener includes a screw rod that penetrates the guide plate and is screwed to the side wall of the channel steel body near the top of the channel steel body. A fastening nut is screwed onto the rod body located on the outer side of the side wall of the channel steel body. An L-shaped pressure plate is fixedly connected to the end of the screw rod located on the inner side of the channel steel body. One end of the L-shaped pressure plate is interlocked and locked with the top of one side of the C-shaped steel structure. The other end of the L-shaped pressure plate is slidably engaged with the inner surface of the top of the channel steel body. Fasteners are provided on both side walls of the channel steel body. The two fasteners are used to fix the tops of the two sides of the C-shaped steel structure.

[0011] Preferably, both the first and second telescopic mechanisms include a fixed part and a telescopic part. The first telescopic mechanism is longitudinally arranged at the top of the support body, and the bottom end of the fixed part of the first telescopic mechanism is detachably and fixedly connected to the top of the support body. The second telescopic mechanism, perpendicular to the front end of the support body, is horizontally arranged at the front end of the support body, and the bottom end of the fixed part of the second telescopic mechanism is detachably and fixedly connected to the front end of the support body. The bottom end of the channel steel body is hinged to the top of the telescopic part, and an angle adjustment mechanism is connected between the outer end of the bottom of the channel steel body and the wall surface of the telescopic part. The device includes a sleeve, a first threaded rod, and a second threaded rod. The two ends of the inner wall of the sleeve are respectively provided with internal threads in opposite directions. One end of the first threaded rod and the second threaded rod are respectively screwed to the two ends of the inner wall of the sleeve. When the sleeve is rotated, the first threaded rod and the second threaded rod move simultaneously toward or away from the sleeve. The outer ends of the first threaded rod and the second threaded rod are respectively hinged to the lower surface of the channel steel body and the outer surface of the telescopic part. The length of the angle adjustment mechanism corresponds to the inclination angle of the bottom inner surface of the channel steel body. When the guide groove and the guide rail cooperate with each other, the inclination angle of the bottom inner surface of the channel steel body is the inclination angle of the inner template.

[0012] Preferably, the top and front ends of the support body have a plurality of bolt holes arranged in a matrix, the bottom end of the fixing part is connected to a base, the base is fixedly connected to the bolt holes by high-strength bolts, and a plurality of first stiffening ribs are fixedly connected between the outer surface of the fixing part and the upper surface of the base; the bottom of the front end and the bottom of the rear end of the support body are respectively provided with a first support plate and a second support plate, the lower surfaces of the first support plate and the second support plate are coplanar with the lower surface of the support body, and a plurality of second stiffening ribs are fixedly provided between the upper surfaces of the first support plate and the second support plate and the front or rear end of the support body, and the first support plate and the second support plate are fixedly connected to the ground by anchor bolts.

[0013] Preferably, the support body includes a cubic outer shell and an inner shell fitted inside the outer shell. Several supporting steel plates are evenly distributed between the outer surface of the inner shell and the inner surface of the outer shell. The inner shell and the outer shell are open at both ends. A sealing plate is welded between the outer edge of the open end of the inner shell and the inner edge of the open end of the outer shell on the same side. The open end of the inner shell is provided with a sealing door. The interior of the inner shell is divided into several storage chambers by cross-sectional partitions. The storage chambers are used to store the first telescopic tube mechanism or the second telescopic mechanism. The outer surface of the sealing plate is fixed with lifting lugs.

[0014] Preferably, hydraulic cylinders are provided at the left and right ends of the front and rear surfaces of the support body. The top of the hydraulic cylinder is fixedly connected to the front or rear end of the support body through a fixing plate, and a traveling wheel is fixedly provided at the bottom end. When the hydraulic cylinder extends, the traveling wheel abuts against the ground, and the four traveling wheels constitute the moving mechanism of the support body. When the hydraulic cylinder retracts, the traveling wheel moves to the upper side of the bottom end of the support body.

[0015] A method for reinforcing formwork on a large-angle exposed concrete sloping wall includes the following steps:

[0016] Step 1: Hoist the reinforcement device to the construction position using the lifting mechanism, open the hydraulic cylinder to make the traveling mechanism work, push the support body, and make the front end of the support body parallel to the wall base line pre-drawn on the fair water sloping wall; retract the hydraulic cylinder to make the traveling wheel return to the initial position, the bottom end of the support body contact the ground, and adjust the levelness of the top of the support body to be horizontal.

[0017] Step 2: Open the sealed door, take out the first telescopic mechanism and the second telescopic mechanism to be used, fix at least two first telescopic mechanisms side by side on the top of the support body, and then fix at least two second telescopic mechanisms side by side on the front end of the support body, so that the first telescopic mechanisms and the second telescopic mechanisms are facing each other. Connect the same guide rail in the guide groove of the facing first telescopic mechanisms and the second telescopic mechanisms. Before connecting the guide rail, adjust the guide groove to the same tilt angle, and adjust the first telescopic mechanism and the second telescopic mechanism to the set length. Place the guide rail in the guide groove of the facing first telescopic mechanism and the second telescopic mechanism respectively and lock it with fasteners. At the same time, make the bottom end of the guide rail abut against the ground where the wall base line is located.

[0018] Step 3: Lift the inner template using the lifting mechanism, align the connecting holes of the guide rail with the threaded holes of the transverse back ribs on the back of the inner template, and fix them together with bolts until the inner template is assembled; install the outer template and fix the inner and outer templates relative to each other using the tie mechanism.

[0019] Step 4: Add a first telescopic mechanism and a second telescopic mechanism according to the stress condition of the inner template. When adding, fix the fixing part of the first telescopic mechanism or the second telescopic mechanism to the preset position of the support body with high-strength bolts. Add several first telescopic mechanisms and second telescopic mechanisms to meet the stress requirements during the pouring of the fair-faced sloping wall. The guide grooves of several first telescopic mechanisms and second telescopic mechanisms are fixedly connected to the corresponding guide rails with fasteners.

[0020] Step 5: Pour the concrete for the sloping wall;

[0021] Step 6: After casting and molding, separate the guide groove from the guide rail, remove the first telescopic mechanism and the second telescopic mechanism from the support body, open the sealing cover, put the first telescopic mechanism and the second telescopic mechanism into the corresponding storage chamber, close the sealing cover, and lift the reinforcement device away using the lifting mechanism.

[0022] Step 7: Remove the guide rails, tie bolts, inner formwork, and outer formwork.

[0023] Preferably, the outer template installation process is the same as steps 1, 2, and 3, except that the support body located on one side of the outer template has several second telescopic mechanisms of different heights installed at its front end.

[0024] The formwork reinforcement system and construction method for a large-angle fair-faced sloping wall of the present invention have the following beneficial effects:

[0025] 1. This invention can effectively reduce the construction difficulty of reinforced fair-faced sloping wall formwork and improve construction efficiency.

[0026] 2. This invention not only facilitates the disassembly of the template, but also allows for the rapid installation and removal of the reinforcement device, thus simplifying the construction process as a whole.

[0027] 3. This invention can precisely adjust the tilt angle and lateral placement angle of the template. The reinforcement device not only reinforces the template, but also provides convenience for workers' operation.

[0028] 4. The reinforcement device of this invention is easy to store, move and transport. The first telescopic mechanism and the second telescopic mechanism can be quickly positioned through the support body. By setting two first telescopic mechanisms and two second telescopic mechanisms, the guide rail and template can be quickly positioned. Based on the construction drawings and the structural dimensions of the reinforcement device, the position of the support body, the installation position and length of the first telescopic mechanism and the second telescopic mechanism, and the inclination angle of the guide groove are calculated in advance, so as to achieve precise and fast construction of the reinforcement of the fair-faced sloping wall template.

[0029] 5. The present invention can also solve the reinforcement construction of fair-faced sloping wall formwork with continuous multi-angle slopes by adjusting the length of the first telescopic mechanism and the second telescopic mechanism, and can achieve various shaping effects.

[0043] Example 1

[0044] A formwork reinforcement system for large-angle finished fair-faced sloping walls, such as Figure 1-7As shown, the system includes an inner template 2, an outer template 1, and a reinforcing device. The inner template 2 and the outer template 1 are connected by a tie mechanism, typically using common tools such as tie rods or U-shaped clamps. The inner template 2 has a reinforcing device on its inner side, which includes a cubic support body 5. The support body 5 has several first telescopic mechanisms 6 at its top and several second telescopic mechanisms 13 at its front end. The tops of the first telescopic mechanisms 6 and the second telescopic mechanisms 13 are respectively provided with guide grooves 30 and fasteners. Several transverse back ribs 3 are evenly distributed on the outer surfaces of the inner template 2 and the outer template 1. Several longitudinally arranged guide rails 4 are evenly distributed along the back of the transverse back ribs 3. The guide rails 4 slide with the guide grooves 30 and are fixedly connected by fasteners. The bottom end of the guide groove 30 is hinged to the top of the first telescopic mechanism 6 or the second telescopic mechanism 13. An angle adjustment mechanism is connected between the guide groove 30 and the first telescopic mechanism 6 or the second telescopic mechanism 13. Several guide grooves 30 correspond one-to-one with several guide rails 4. When several angle adjustment mechanisms adjust the guide grooves to a set angle, they position the inclination angle of the inner template 2. This positioning method is also applicable to the outer template 1. When the front end face of the support body 5 is parallel to the wall root marking line (not shown in the figure) on the inner side of the fair-faced sloping wall, the inner template 2 is adjusted to the set horizontal placement angle by adjusting the length of the second telescopic mechanism. Usually, the length of the second telescopic mechanism can be pre-calculated and set. Before construction, the length of the second telescopic mechanism is pre-adjusted. After installation, it is directly inserted into the inner template to achieve the set horizontal placement angle (the bottom end of the inner template is aligned with the wall root marking line). The bottom end of the guide rail 4 is hinged with a locking plate 31. The locking plate 31 is fixedly connected to the ground by anchor bolts 32.

[0045] Example 2

[0046] Based on Example 1, this example discloses:

[0047] like Figure 1-7 As shown, both the inner template 2 and the outer template 1 are assembled from one or more template bodies. The transverse back rib 3 is made of channel steel, and the bottom end of the flange plate of the channel steel is fixedly connected to the outer surface of the inner template 2 or the outer template 1. Several tie bolt holes 16 are evenly distributed on the top of the transverse back rib 3. The tie mechanism fixes the inner template 2 and the outer template 1 through the corresponding tie bolt holes; that is, the tie bolt holes should pass through the inner template or the outer template. The guide rail 4 is a C-shaped steel structure with the open end facing outwards. Several connecting holes are evenly distributed at the bottom of the C-shaped steel structure. A threaded hole is provided at the top of the transverse back rib 3 opposite to the connecting hole. The guide rail 4 is fixedly connected to the transverse back rib 3 by bolts 17 that pass through the connecting hole and are screwed into the threaded hole. The guide rail and the transverse back rib provide the inner template with sufficient compressive strength.

[0048] Example 3

[0049] Based on Example 2, this example discloses:

[0050] like Figure 1-7 As shown, the length of the support 5 is the same as the width of the inner template 2. The guide groove 30 includes a channel steel body. Guide plates 20 arranged along the top direction of the channel steel body are welded to the inner surfaces of the two side walls of the channel steel body. The two ends of the opening of the C-shaped steel structure are slidably engaged with the outer surface of the guide plate 20 on the same side. The width of the two ends of the opening is smaller than the width of the guide plate 20, which facilitates the fixing of the guide rail 4 by fasteners. The outer surface of the C-shaped steel structure is slidably engaged with the inner surface of the side wall of the channel steel body on the same side. The fasteners include those that penetrate the guide plate 20 and are close to the guide plate 20. A screw 22 is threaded to the side wall of the channel steel body on one side of the top of the channel steel body. A fastening nut 23 is threaded onto the rod body of the screw 22 located on the outer side wall of the channel steel body. An L-shaped pressure plate 21 is fixedly connected to the end of the screw 22 located on the inner side of the channel steel body. One end of the L-shaped pressure plate 21 is interlocked and locked with the top of one side of the C-shaped steel structure. The other end of the L-shaped pressure plate 21 is slidably engaged with the inner surface of the top of the channel steel body. Fasteners are provided on both side walls of the channel steel body, and the two fasteners are respectively used to fix the top of the two sides of the C-shaped steel structure. After fixing, the up-down, left-right, and back-and-forth movement of the guide rail is restricted, which fully ensures the stability of the inner template (the principle of reinforcing the outer template is the same).

[0051] Example 4

[0052] Based on Example 3, this example discloses:

[0053] like Figure 1-7As shown, both the first telescopic mechanism 6 and the second telescopic mechanism 13 include a fixed part and a telescopic part. Typically, the first and second telescopic mechanisms can be selected from mechanical threaded sleeve structures, hydraulic cylinder structures, or pneumatic cylinder structures. If a mechanical threaded sleeve structure is selected (a support rod is threaded inside the sleeve; the sleeve is the fixed part, and the support rod is the telescopic part), the length can be pre-adjusted by rotation. The top of the support body 5 is longitudinally provided with the first telescopic mechanism 6, and the bottom end of the fixed part of the first telescopic mechanism 6 is detachably fixedly connected to the top of the support body 5. The front end of the support body 5 is horizontally provided with the second telescopic mechanism 13 perpendicular to the front end of the support body 5, and the bottom end of the fixed part of the second telescopic mechanism 13 is detachably fixedly connected to the front end of the support body 5. The bottom end of the channel steel body is connected to the telescopic part... The top of the telescopic section is hinged. An angle adjustment mechanism is connected between the outer end of the bottom of the channel steel body and the wall surface of the telescopic section. The angle adjustment mechanism includes a sleeve 24, a first threaded rod 26, and a second threaded rod 25. The two ends of the inner wall of the sleeve 24 are respectively provided with internal threads in opposite directions. One end of the first threaded rod and the second threaded rod are respectively screwed to the two ends of the inner wall of the sleeve. When the sleeve is rotated, the first threaded rod and the second threaded rod move simultaneously toward or away from the sleeve. The outer ends of the first threaded rod and the second threaded rod are respectively hinged to the lower surface of the channel steel body and the outer surface of the telescopic section. The length of the angle adjustment mechanism corresponds to the inclination angle of the inner surface of the bottom of the channel steel body. When the guide groove and the guide rail cooperate with each other, the inclination angle of the inner surface of the bottom of the channel steel body is the inclination angle of the inner template.

[0054] Example 5

[0055] Based on Example 4, this example discloses:

[0056] like Figure 4 As shown, the top and front ends of the support body 5 have a plurality of bolt holes 29 arranged in a matrix. The bottom end of the fixing part is connected to a base 19, which is fixedly connected to the bolt holes by high-strength bolts. A plurality of first stiffening ribs 7 are also fixedly connected between the outer surface of the fixing part and the upper surface of the base. The bottom of the front end and the bottom of the rear end of the support body 5 are respectively provided with a first support plate 14 and a second support plate 9. The lower surfaces of the first support plate 14 and the second support plate 9 are coplanar with the lower surface of the support body 5. A plurality of second stiffening ribs 8 are also fixedly provided between the upper surfaces of the first support plate 14 and the second support plate 9 and the front or rear end of the support body 5. The first support plate 14 and the second support plate 9 are fixedly connected to the ground by anchor bolts. For the sake of brevity, only part of the first telescopic mechanism and the second telescopic mechanism are shown in the figure. The number and installation position of the first telescopic mechanism and the second telescopic mechanism are adjusted according to actual construction needs. The function of the first support plate and the second support plate is to improve the stability and support capacity of the support body.

[0057] Example 6

[0058] Based on Example 5, this example discloses:

[0059] like Figure 1-7 As shown, the support body 5 includes a cubic outer shell 5-1 and an inner shell 5-2 nested inside the outer shell. Several supporting steel plates 5-3 are evenly distributed between the outer surface of the inner shell and the inner surface of the outer shell. The inner shell and the outer shell are open at both ends. A sealing plate 5-5 is welded between the outer edge of the open end of the inner shell and the inner edge of the open end of the outer shell on the same side. The open end of the inner shell is provided with a sealing door 5-6. The interior of the inner shell is divided into several storage chambers 5-8 by cross-sectional partitions 5-4. The storage chambers 5-8 are used to store the first telescopic tube mechanism or the second telescopic mechanism. The outer surface of the sealing plate 5-5 is fixed with lifting lugs (first lifting lug 15, second lifting lug 5-7), which are used to connect the lifting mechanism.

[0060] Example 7

[0061] Based on Example 6, this example discloses:

[0062] like Figure 1 , 2 As shown, hydraulic cylinders 11 are respectively installed at the left and right ends of the front and rear surfaces of the support body 5. The top of the hydraulic cylinder 11 is fixedly connected to the front or rear end of the support body 5 through a fixing plate 10, and the bottom end is fixedly equipped with a traveling wheel 12. When the hydraulic cylinder 11 extends, the traveling wheel 12 abuts against the ground, and the four traveling wheels 12 constitute the moving mechanism of the support body 5. When the hydraulic cylinder 11 retracts, the traveling wheel 12 moves to the upper side of the bottom end of the support body 5. The purpose of setting up the traveling mechanism is to facilitate the adjustment of the position of the support body during construction or the movement of the reinforcement device in other situations.

[0063] Example 8

[0064] Based on Example 7, this example discloses:

[0065] A method for reinforcing formwork on a large-angle exposed concrete sloping wall, such as... Figure 1-7 As shown, it includes the following steps:

[0066] Step 1: Hoist the reinforcement device to the construction position using the lifting mechanism, open the hydraulic cylinder to make the traveling mechanism work, push the support body, and make the front end of the support body 5 parallel to the wall base line pre-drawn on the fair water sloping wall; retract the hydraulic cylinder 11 to make the traveling wheel 12 return to the initial position, and the bottom end of the support body 5 contact the ground. Adjust the level of the top of the support body 5 to be level (leveling can be achieved by raising a local area).

[0067] Step 2: Open the sealed door, take out the first and second telescopic mechanisms to be used, and fix at least two first telescopic mechanisms side by side on the top of the support body. Then fix at least two second telescopic mechanisms side by side on the front end of the support body, so that the first and second telescopic mechanisms are opposite each other (i.e., the four guide grooves are arranged in a rectangle). Connect the same guide rail in the guide grooves of the opposite first and second telescopic mechanisms. Before connecting the guide rail 4, adjust the guide grooves to the same inclination angle and adjust the first telescopic mechanism 6 and the second telescopic mechanism 13 to the set length. This length should be calculated in advance according to the construction drawings. The length of the first and second telescopic mechanisms can be adjusted on site or in advance. Place the guide rail 4 in the guide grooves of the opposite first and second telescopic mechanisms respectively and lock it with fasteners. At the same time, make the bottom end of the guide rail abut against the ground where the wall base line is located, and fix it to the ground with the locking plate 31. After the two guide rails are fixed, the position of the template can be positioned.

[0068] Step 3: Lift the inner template 2 using the lifting mechanism, align the connecting holes of the guide rail 4 with the threaded holes of the transverse back rib 3 on the back side of the inner template, and fix them together with bolts until the inner template 2 is assembled; install the outer template 1, and fix the inner template 2 and the outer template 1 relative to each other using the tie mechanism; the tie mechanism, i.e., the connection method of tie bolts, is existing technology and will not be described in detail.

[0069] Step 4: Add a first telescopic mechanism and a second telescopic mechanism according to the stress condition of the inner template. When adding, fix the fixing part of the first telescopic mechanism or the second telescopic mechanism to the preset position of the support body with high-strength bolts. Add several first telescopic mechanisms and second telescopic mechanisms to meet the stress requirements during the pouring of the fair-faced sloping wall. The guide grooves of several first telescopic mechanisms and second telescopic mechanisms are fixedly connected to the corresponding guide rails with fasteners.

[0070] Step 5: Pour the concrete for the sloping wall;

[0071] Step 6: After casting and molding, separate the guide groove from the guide rail, remove the first telescopic mechanism and the second telescopic mechanism from the support body, open the sealing cover, put the first telescopic mechanism and the second telescopic mechanism into the corresponding storage chamber, close the sealing cover, and lift the reinforcement device away using the lifting mechanism.

[0072] Step 7: Remove the guide rails, tie bolts, inner formwork, and outer formwork.

[0073] Example 9

[0074] Based on Example 8, this example discloses:

[0075] like Figure 1-7As shown, the installation process of the outer template 1 is the same as steps 1, 2, and 3, except that the support 5 located on one side of the outer template 1 is only equipped with several second telescopic mechanisms of different heights at its front end. Since the outer template is also inclined, its installation is also very difficult. Therefore, by setting up a reinforcement device, the outer template can be installed quickly.

[0076] The working principle of this invention:

[0077] 1. For example Figure 9 As shown, in step 2, the two first telescopic mechanisms 6 and the two second telescopic mechanisms 13, a total of four guide grooves, position the two guide rails. Figure 9 As shown, after the two guide rails are positioned, their inner end faces are coplanar, allowing them to connect to the transverse back rib 3 on the back of the inner template 2. In other words, the template only needs to be connected to the guide rails, and the template will be positioned according to the set tilt angle. This invention, through the above design, greatly simplifies the template positioning process and ensures precise positioning.

[0078] 2. For example Figure 9 As shown, the guide rail is fixed to the ground by a locking plate, thus establishing a hinged relationship between the guide rail and the ground. Several first telescopic mechanisms 6 are arranged longitudinally, bearing the longitudinal component of the force applied by the fair-faced concrete sloping wall during casting and molding. Several second telescopic mechanisms are arranged horizontally, bearing the horizontal component of the force applied by the fair-faced concrete sloping wall during casting and molding. The first and second telescopic mechanisms cooperate to provide a solid support effect. Specifically, due to the longitudinal support force of the first telescopic mechanisms, there is no need to worry about the second telescopic mechanisms deforming due to excessive longitudinal pressure. Similarly, due to the horizontal support force of the second telescopic mechanisms, there is no need to worry about the first telescopic mechanisms deforming due to excessive horizontal thrust. To further consolidate the effect, the invention also includes a first stiffening rib 7, further strengthening the first and second telescopic mechanisms.

[0079] 3. Compared with the prior art which contacts the ground through rods, the contact area between the bottom of the support body 5, the bottom of the first support plate and the second support plate of the present invention and the ground is increased by several times. Moreover, the first telescopic mechanism and the second telescopic mechanism are connected into an integral structure through the support body, which can significantly improve the stability and support effect of the template reinforcement system.

[0080] 4. When the surface of the fair-faced concrete sloping wall consists of multiple continuous sloping surfaces due to special construction requirements, this invention can achieve a reinforcement effect by adjusting the height of the first or second telescopic mechanism. Taking two continuous sloping surfaces with different angles as an example... Figure 10As shown, the guide rail 4 is composed of an integrally formed first guide rail 4-1 and second guide rail 4-2 (i.e., the guide rail is composed of several guide rail segments connected together). After the first guide rail 4-1 is reinforced by the first telescopic mechanism 6 and the second telescopic mechanism 13, the second guide rail 4-2 can be reinforced by a portion of the first telescopic mechanism 6. Then, the inner template is assembled and connected on the guide rail 4 (which can be understood as the first telescopic mechanism and the second telescopic mechanism sequentially reinforcing and supporting each guide rail segment, and the inner template is installed after the guide rail is positioned). Therefore, based on the above design of the present invention, the reinforcement construction of the fair-faced sloping wall template for continuous multi-angle slopes can be realized, and various shaping effects can be achieved.

[0081] 5. The bolt holes on the support body of this invention are arranged in a matrix. Each bolt hole has its own coordinate position relative to the support body. The support body can also be set in a suitable position according to the architectural drawings of the fair-faced sloped wall. Since the structural dimensions of the support body are known, the workers can draw the reinforcement system of this invention into the drawings based on the fair-faced sloped wall drawings. This allows for detailed analysis and setting of the position, height, guide groove inclination angle, and stress conditions of several first and second telescopic mechanisms in the entire reinforcement system. Through engineering practice, the parameters of the reinforcement system are accumulated. These parameters include the number, position, height, and guide groove inclination angle of the aforementioned first and second telescopic mechanisms, thus providing the optimal solution for the reinforcement support of fair-faced sloped walls of various sizes and types. Once the solution is determined, it can be quickly assembled on-site, thus significantly improving the efficiency of the reinforcement support template.
