Description

Technical Field

[0001] This invention relates to the field of reinforced concrete shear wall construction technology, and is applicable to the construction of inclined ultra-thick reinforced concrete shear wall formwork structures. Background Technology

[0002] The application of inclined, ultra-thick, rigid concrete shear wall formwork structures is becoming increasingly widespread; however, the unique characteristics of this structure make its high-formwork construction quite challenging. Before pouring the shear wall concrete, a guide wall is typically constructed according to the shear wall structure's axis. The completed large formwork is then fixed to the guide wall, and the gaps are sealed with materials such as plastic film to prevent grout leakage during concrete pouring. However, this joint remains a difficult point in controlling the shear wall construction process, and the connection between the guide wall and the newly constructed shear wall is prone to becoming a structural weak point. Furthermore, during the construction of inclined concrete shear walls, the large formwork on both sides of the shear wall is under unbalanced stress, making it prone to displacement and collapse due to insecure formwork fixing.

[0003] Therefore, there is an urgent need for a construction method for a reliable and stable formwork support structure for inclined ultra-thick rigid concrete shear walls. Summary of the Invention

[0004] In view of the above-mentioned shortcomings in the existing technology, the purpose of this invention is to provide a construction method for inclined ultra-thick rigid concrete shear wall formwork structure.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: A construction method for an inclined ultra-thick rigid concrete shear wall formwork structure includes the following steps:

[0006] S00, Construction Guide Wall:

[0007] During the construction of the base slab, guide walls are constructed according to the axis of the shear wall structure.

[0008] S10. Install the template bottom frame:

[0009] Install a formwork bottom frame around the perimeter of the guide wall to fix the bottom of the shear wall formwork;

[0010] The bottom frame of the template is a frame structure, and there is a gap between the bottom frame of the template and the guide wall to match the shear wall template.

[0011] S20, Fixed template bottom frame;

[0012] Anchor the bottom frame of the template to the base plate;

[0013] S30. Install shear wall stiffening plates:

[0014] The stiffening plates are arranged at intervals in both the longitudinal and transverse directions, and adjacent stiffening plates are connected by connecting rods;

[0015] S40. Install shear wall formwork and supporting structure:

[0016] S41. Template Installation:

[0017] The formwork on both sides of the shear wall is hoisted into place, with the bottom of the formwork extending into the reserved cavity of the bottom frame of the formwork.

[0018] S42. Installation of tie rods:

[0019] The templates on both sides are fixed by pulling and fixing them together using back ribs, round tubes, mountain-shaped clips and screws arranged at intervals;

[0020] S43, Right-side support installation:

[0021] The right-side template is supported by several struts, and the bottom of the struts is fixed by the strut bases anchored to the base plate.

[0022] S44, Left side bracing installation:

[0023] Connect the left template to the third base using a tie rod;

[0024] S50, Shear Wall Casting and Curing:

[0025] S51. Pour shear wall concrete into the cavity of the shear wall;

[0026] S52. Use the curing pipes installed inside the shear wall formwork for curing.

[0027] Furthermore, in step S10, the template bottom frame includes a lower left horizontal rib located at the junction of the left side of the guide wall and the bottom plate, and an upper left horizontal rib at the top of the left side of the guide wall. The lower left horizontal rib and the upper left horizontal rib are arranged in parallel, and a left vertical rib is arranged between the lower left horizontal rib and the upper left horizontal rib.

[0028] On the right side of this guide wall, a lower right horizontal rib is arranged at the junction of the right side of the guide wall and the bottom plate, and an upper right horizontal rib is arranged at the top of the right side of the guide wall. The lower right horizontal rib and the upper right horizontal rib are arranged in parallel, and a right vertical rib is arranged between the lower right horizontal rib and the upper right horizontal rib.

[0029] On the outer perimeter of the side panel on the side of the guide wall, there are upper frames connecting the upper left and upper right horizontal ribs, and lower frames connecting the lower left and lower right horizontal ribs. There are limiting blocks between the lower frames and the side panels.

[0030] Furthermore, in step S10, for the aforementioned template bottom frame, the lower left horizontal rib, upper left horizontal rib, left vertical rib, lower right horizontal rib, upper right horizontal rib, and right vertical rib all have matching shear wall template gaps with the guide wall.

[0031] Furthermore, in step S20, the lower frame extends to the right side of the guide wall, is pressed onto the base plate using the first base, and is anchored to the base plate using anchor rods. The lower frame extends to the left side of the guide wall, is pressed onto the base plate using the second and third bases, and is anchored to the base plate using anchor rods.

[0032] Furthermore, in step S30, internal threaded rods are arranged at intervals in a direction perpendicular to the stiffening plate and connected to the stiffening plate or connecting rod. Both ends of the internal threaded rods have internal sleeves, and the two opposing internal sleeves are the two sides of the shear wall casting cavity.

[0033] Furthermore, in step S42, the screw is divided into an inner screw and an outer screw. The same screw unit consists of one inner screw and two outer screws, and the inner screw and the outer screw are connected by a sleeve.

[0034] When installing the shear wall stiffening plate, the internal thread and sleeve have already been installed;

[0035] During the installation of the tie rod, each external threaded rod is inserted into each sleeve to form a complete threaded rod unit.

[0036] Furthermore, in step S42, the screw itself is used as a template tie rod, and the inner screw and the inner sleeves on both sides of the inner screw abut against the inner sides of the templates on both sides are used to form the template’s inner support, which is used to replace the traditional pad block inner support.

[0037] After the shear wall construction is completed, the outer threaded rods are removed, and the inner threaded rods are left inside the shear wall as permanent structures. The inner threaded rods are connected to the stiffening plates or connecting rods to serve as load-bearing structures.

[0038] Furthermore, in step S44, the third bases are arranged at intervals and connected by longitudinal braces. Each third base has a tie point at its top. The left template has several upper fixing points and several lower fixing points. Tie rods are used to connect the tie points to the fixing points or lower fixing points.

[0039] Furthermore, in step S52, the template has vertical pipes arranged at intervals, which run through the top and bottom of the template. The upper end of the template side has a water inlet pipe that connects to each vertical pipe, and the lower end of the template side has a water outlet pipe that also connects to each vertical pipe.

[0040] During the pouring of ultra-thick concrete shear walls, cooling water is circulated into the inlet of the inlet pipe. The cooling water flows into each vertical pipe and carries away the heat of hydration released by the concrete, and flows out from the outlet of the outlet pipe to achieve internal curing of the ultra-thick concrete shear walls.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. This invention utilizes the guide wall body and the base to install the template bottom frame, and uses the template bottom frame to install the bottom of the shear wall template, avoiding the use of pre-reserved holes in the guide wall for template tie fixing, and preventing the formation of quality hazards at the root of the shear wall due to perforation of the guide wall.

[0043] 2. This invention utilizes a combination of tension and bracing to fix the shear wall formwork, thereby improving the stability of the formwork.

[0044] 3. This invention, through the combined forming of a screw structure and installation method, allows the screw itself to serve as a template tie rod. Simultaneously, the inner screw and the inner sleeves on both sides of the inner screw abutting against the inner surfaces of the templates on both sides form an internal support for the template, replacing the traditional pad block internal support. Furthermore, since the screw is detachable, after the shear wall construction is completed, the outer screw can be removed, leaving the inner screw inside the shear wall as a permanent structure. Moreover, the inner screw is connected to the stiffening plate or connecting rod, thus it can be considered as a load-bearing structure.

[0045] 4. This invention utilizes internal pipes within the template for cooling water circulation and heat dissipation during curing, thus achieving internal curing of ultra-thick concrete shear walls. Attached Figure Description

Therefore, the above terms should not be construed as limitations on this application.

[0057] Please see Figure 1-7 As shown, the construction method for this inclined ultra-thick reinforced concrete shear wall formwork structure includes the following steps:

[0058] Step 1: Constructing Guide Wall 2. During the construction of the base slab 1, guide wall 2 is constructed according to the axis of the shear wall structure.

[0059] Step 2: Install the formwork base frame. Install the formwork base frame around the perimeter of the guide wall 2 to fix the bottom of the shear wall formwork 3.

[0060] The bottom frame of the template is a frame structure, with a gap between the bottom frame and the guide wall 2 to match the shear wall template 3. The bottom frame includes a lower left horizontal rib 16 located at the junction of the left side of the guide wall 2 and the base plate 1, and an upper left horizontal rib 17 at the top left side of the guide wall 2. The lower left horizontal rib 16 and the upper left horizontal rib 17 are arranged parallel to each other, and a left vertical rib 18 is arranged between the lower left horizontal rib 16 and the upper left horizontal rib 17. Similarly, on the other side, i.e. the right side of the guide wall 2, a lower right horizontal rib 24 located at the junction of the right side of the guide wall 2 and the base plate 1, and an upper right horizontal rib 25 at the top right side of the guide wall 2 are arranged. The lower right horizontal rib 24 and the upper right horizontal rib 25 are arranged parallel to each other, and a right vertical rib 23 is arranged between the lower right horizontal rib 24 and the upper right horizontal rib 25. Around the side plate 13 on the side of the guide wall 2, there are upper frame 14 connecting the upper left horizontal rib 17 and the upper right horizontal rib 25, and lower frame 11 connecting the lower left horizontal rib 16 and the lower right horizontal rib 24. There is a limiting block 12 between the lower frame 11 and the side plate 13.

[0061] For the bottom frame of the above template, there are gaps between the lower left horizontal rib 16, the upper left horizontal rib 17, the left vertical rib 18, the lower right horizontal rib 24, the upper right horizontal rib 25, and the right vertical rib 23 and the guide wall 2 to match the shear wall template 3.

[0062] Step 3: Secure the template bottom frame. To further ensure the template bottom frame from Step 2 is securely fixed, anchor the template bottom frame to the base plate 1.

[0063] The lower frame 11 of the template bottom frame extends to the right side of the guide wall 2, and is pressed and fixed to the base plate 1 by the first base 5. The first base 5 and the base plate 1 are anchored and connected by the anchor rod 9. The lower frame 11 of the template bottom frame extends to the left side of the guide wall 2, and is pressed and fixed to the base plate 1 by the second base 6 and the third base 7. The second base 6 and the third base 7 are anchored and connected to the base plate 1 by the anchor rod 9.

[0064] Step 4: Install shear wall stiffening plate 32:

[0065] The pre-reserved steel bars of the guide wall 2 are used to connect the stiffening plate 32 of the shear wall.

[0066] The rigid plates 32 are arranged at intervals in the longitudinal and transverse directions, and adjacent rigid plates 32 are connected by connecting rods 39. In the direction perpendicular to the rigid plates 32, internal threaded rods 37 are arranged at intervals to connect the rigid plates 32 or the connecting rods 39. Both ends of the internal threaded rods 37 have internal sleeves 36, and the two opposing internal sleeves 36 are the two sides of the shear wall casting cavity 4.

[0067] Step 5: Install shear wall formwork 3 and supporting structure.

[0068] S1. Installation of formwork 3. Hoist the formwork 3 on both sides of the shear wall into place, with the bottom of formwork 3 extending into the reserved cavity of the bottom frame of the formwork.

[0069] S2. Installation of tie rods. The templates on both sides 3 are fixed by tie rods 28, round tubes 29, mountain-shaped clips 30 and screws arranged at intervals.

[0070] The screw 31 consists of an inner screw 37 and outer screws 38. Each screw 31 unit comprises one inner screw 37 and two outer screws 38, connected by sleeves. The inner screw 37 and outer screws 38 are already installed when the shear wall stiffening plate 32 is installed. During the tie rod installation, each outer screw 38 is inserted into its respective sleeve to form a complete screw 31 unit.

[0071] By adopting this combined screw rod 31 structure and installation method, the screw rod 31 itself can serve as a tie rod 20 for the template 3. At the same time, the inner screw rod 37 and the inner sleeves 36 on both sides of the inner screw rod 37 abutting against the inner sides of the template 3 on both sides form the inner support of the template 3, which is used to replace the traditional pad block inner support. In addition, since the screw rod 31 is detachable, after the shear wall construction is completed, the outer screw rod 38 can be removed, and the inner screw rod 37 can be left inside the shear wall as a permanent structure. The inner screw rod 37 is connected to the stiffening plate 32 or the connecting rod 39, so it can be considered as a load-bearing structure.

[0072] S3. Right side support installation. Several struts 27 are used to support the right side template 3, and the bottom of the struts 27 are fixed by the strut bases 26 anchored to the base plate 1.

[0073] S4. Installation of left-side bracing. Connect the left-side template 3 to the third base 7 using tie rod 20.

[0074] Specifically, the third bases 7 are arranged at intervals and connected by longitudinal bracing 15. Each third base 7 has a tie point 8 at its top. The left template 3 has several upper fixing points 22 and several lower fixing points 21. The tie point 8 is connected to the upper fixing point 22 or the lower fixing point 21 by the tie rod 20.

[0075] Step 6: Shear wall pouring and curing.

[0076] S1. Pour shear wall concrete into the shear wall casting cavity 4.

[0077] S2. Use the curing pipes installed inside the shear wall formwork 3 for curing.

[0078] Specifically, the formwork 3 has spaced vertical pipes 35 that run through the top and bottom of the formwork 3. A water inlet pipe 33 is located at the upper side of the formwork 3, connecting to each vertical pipe 35. A water outlet pipe 40 is located at the lower side of the formwork 3, also connecting to each vertical pipe 35. During the pouring of the ultra-thick concrete shear wall, cooling water is circulated in through the inlet 34 of the water inlet pipe 33. The cooling water flows into each vertical pipe 35, carrying away the heat of hydration released by the concrete, and flows out from the outlet 41 of the outlet pipe 40, thus achieving internal curing of the ultra-thick concrete shear wall.

[0079] The installation of the inclined ultra-thick stiff concrete shear wall formwork structure is achieved through the construction method described above for the inclined ultra-thick stiff concrete shear wall formwork structure.

[0082] Although this article uses a lot of terms such as base plate 1, guide wall 2, formwork 3, shear wall casting cavity 4, first base 5, second base 6, third base 7, tie point 8, anchor rod 9, horizontal brace 10, lower frame 11, limiting block 12, side plate 13, upper frame 14, longitudinal brace 15, lower left horizontal rib 16, upper left horizontal rib 17, left vertical rib 18, tie rod 20, lower fixing point 21, upper fixing point 22, right vertical rib 23, lower right horizontal rib 24, upper right horizontal rib 25, strut base 26, strut 27, back rib 28, round pipe 29, mountain-shaped clip 30, screw rod 31, stiffening plate 32, water inlet pipe 33, water inlet 34, vertical pipe 35, inner sleeve 36, inner screw rod 37, outer screw rod 38, connecting rod 39, water outlet pipe 40, and water outlet 41, the possibility of using other terms cannot be ruled out. The use of these terms is merely for the convenience of describing and explaining the nature of this application; interpreting them as any kind of additional limitation would be contrary to the spirit of this application.
