Description

Technical Field

[0001] The invention belongs to the technical field of concrete pouring, and in particular relates to a construction method for pouring concrete on the outer side of an exterior wall of a single steel plate wall. Background Art

[0002] Lateral force-resisting structures are functional components of a building's structure that resist lateral loads (such as wind and seismic loads). For high-rise and steel-framed buildings, lateral force-resisting structures are key to the overall structural design. Steel plate shear walls are a new type of lateral force-resisting structure in steel buildings. Compared to traditional steel bracing, concrete shear walls, or core tube structures, these structures offer advantages such as easier implementation of multiple seismic lines of defense, ease of fabrication and construction, and the potential for increased usable building area.

[0003] However, the compressive stability bearing capacity of flat steel plates is low and they generally cannot withstand vertical loads. In order to achieve better shear stiffness, the stability of the steel plates needs to be ensured. The stable bearing capacity of the steel plates can be improved by increasing the plate thickness, setting stiffening ribs, and attaching precast concrete slabs.

[0004] Prior art discloses a patented invention entitled "Corrugated Single Steel Plate Wall System and Construction Method" (Application Publication No.: CN107514075A). This invention features steel stiffening ribs welded to both sides of the corrugated steel plate. However, for high-rise corrugated single steel plate walls, placing concrete on the exterior of the wall can improve the steel plate's bearing capacity and is an ideal structure for such building construction. However, pouring concrete on the exterior of the wall presents a technical challenge for those skilled in the art.

[0005] The prior art discloses technical solutions for pouring concrete for exterior walls, such as the invention patent entitled "A Method for Pouring Exterior Wall Concrete with a Built-in Insulation Integrated System" (Application Publication Number: CN115162737A), which sets an exterior wall formwork and completes the pouring through a distribution hopper and a flat-mouth pump pipe installed on the exterior wall formwork. However, when the height of the single steel plate wall is high, the height of the concrete to be poured is high, resulting in loose concrete pouring. At the same time, the height of the formwork to be built is very high, posing a safety hazard. In addition, the built-in insulation board, self-compacting concrete, exterior wall formwork, and square timber keels are connected into an integral structure using tension bolts. After the concrete solidifies, the exterior wall formwork and square timber keels are set on the outside of the concrete, and other decorative components cannot be set on the outside of the concrete. Summary of the Invention

[0006] The present invention aims to address the aforementioned technical problems existing in the prior art by providing a construction method for pouring concrete on the exterior of a single steel plate wall. Concrete is poured layer by layer, reducing the concrete pouring height, facilitating dense concrete formation, improving the quality of the concrete pour, and effectively enhancing the bearing capacity of the single steel plate wall. Furthermore, the formwork is supported by a complete truss unit, increasing its load-bearing capacity. Even with high concrete fluidity, the formwork is less likely to deform, meeting the requirements of top-down concrete pouring. Furthermore, the concrete poured in this application is exposed, allowing for the placement of other decorative elements on the exterior of the concrete.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] The construction method of pouring concrete on the outer side of the single steel plate wall is characterized by comprising the following steps:

[0009] a. Processing to obtain steel plate walls, and then fixing the steel plate walls and steel beams to obtain an integrated steel component.

[0010] b. Adjust the horizontal and vertical positions of the integrated steel member, then fix the integrated steel member and the steel column, and simultaneously fix the upper and lower adjacent sections of the integrated steel member to obtain a single steel plate wall.

[0011] c. Measure and record the installation errors of steel columns and steel beams, and feed the errors back into the construction drawings and information models.

[0012] d. According to the measurement data and model information in step c, complete the processing and production of fixed support 1 and fixed support 2, then open through holes on fixed support 1 and fixed support 2, and weld connecting sleeves in the through holes. The connecting sleeves are provided with threaded holes. Then, fix fixed support 1 to the set position of the steel column, and fix fixed support 2 to the set position of the steel beam.

[0013] e. Process the first connecting support truss and the second connecting support truss, position the first connecting support truss on the fixed support 1, position the second connecting support truss on the fixed support 2, then screw the connecting rod into the connecting hole of the first connecting support truss, and screw the connecting rod into the corresponding threaded hole on the fixed support 1, then screw the connecting rod into the connecting hole of the second connecting support truss, and screw the connecting rod into the corresponding threaded hole on the fixed support 2.

[0014] f. Measure the distance between the first connecting support truss and the second connecting support truss, adjust the processing size of the horizontal support truss, and complete the processing and production of the horizontal support truss. Then fix the horizontal support truss between the first connecting support truss and the second connecting support truss, and then fix the edge support truss on the first connecting support truss to form the entire truss unit.

[0015] g. Fix the formwork on the entire truss unit.

[0016] h. Fix the baffle on the entire truss unit. The template and the baffle form a casting space. Then install the first lifting support on the top of the first connecting support truss and the second connecting support truss. Install the second lifting support on the uppermost fixed support 1 and fixed support 2. The second lifting support and fixed support 1 are arranged correspondingly. The first lifting support and the second lifting support are both provided with fixed pulleys. Then install a lifting device on the single steel plate wall, and wrap the rope of the lifting device around the fixed pulleys of the first lifting support and the second lifting support. Then install a grouting hopper on the truss unit. The grouting hopper is located above the casting space.

[0017] i. Grouting is poured into the pouring space through the grouting hopper to form the first concrete layer.

[0018] j. Unscrew the connecting rods of the first connecting support truss and the second connecting support truss, lift the entire truss unit to the upper floor through the rope of the lifting device, then screw the connecting rod into the connecting hole of the first connecting support truss, and screw the connecting rod into the threaded hole on the corresponding fixed support one, then screw the connecting rod into the connecting hole of the second connecting support truss, and screw the connecting rod into the threaded hole on the corresponding fixed support two, and grouting is done into the pouring space through the grouting hopper to form a second concrete layer. The second concrete layer and the first concrete layer form an integral structure.

[0019] k. Repeat step j to complete the concrete pouring.

[0020] Further, after step b is completed, a steel mesh is wrapped around the single steel plate wall.

[0021] Furthermore, in step e, when positioning the first connecting support truss and the second connecting support truss, according to construction requirements, gaskets are set between the first connecting support truss and the fixed support one, and between the second connecting support truss and the fixed support two, so that the first connecting support truss and the second connecting support truss are in the same horizontal position.

[0022] Furthermore, in step f, the first connecting support truss, the second connecting support truss, the horizontal support truss and the edge support truss are all fixed with corbels, and two adjacent corbels are fixed by bolts.

[0023] Furthermore, after the first connecting support truss and the second connecting support truss are processed, connecting plates are welded on both sides of the first connecting support truss and both sides of the second connecting support truss. When fixing the template, the template and the connecting plates are welded and fixed.

[0024] Furthermore, in step h, the grouting hopper installation specifically includes:

[0025] (1) A first sliding beam is fixed on the top of the entire truss unit, and the first sliding beam is arranged along the width direction of the single steel plate wall.

[0026] (2) The first sliding block and the second sliding beam are welded and fixed, and then the first sliding block is slid onto the first sliding beam. At this time, the second sliding beam is arranged along the length direction of the single steel plate wall.

[0027] (3) Connect and fix the grouting hopper and the second sliding block, and then slide the second sliding block onto the second sliding beam.

[0028] (4) Slide the first sliding block on the first sliding beam. After the adjustment is completed, turn the limit bolt on the first sliding block so that the limit bolt presses against the first sliding beam. Then slide the second sliding block on the second sliding beam. After the adjustment is completed, turn the limit bolt on the second sliding block so that the limit bolt presses against the second sliding beam.

[0029] Furthermore, L-shaped plates are welded at the upper and lower ends of the steel column. When step h is completed, the limit plates are fixed between the L-shaped plates by connecting bolts, and a limit groove is formed between the limit plate and the steel column. When installing the baffle, the horizontal plate and the vertical plate are welded into a connecting frame, and then the baffle is welded to the horizontal plate of the connecting frame, and then the threaded rod is welded on the inner side of the horizontal plate. According to the position of the threaded rod, a mounting hole is opened on the edge support truss, and then the threaded rod of the connecting frame is inserted into the mounting hole. At the same time, the baffle passes through the limit groove, and then the nut is screwed into the threaded rod and locked. When the entire truss unit is lifted, the baffle moves upward in the limit groove.

[0030] Furthermore, after step k is completed, mortar is applied to the embedded areas of the fixed support 1 and the fixed support 2 in the concrete.

[0031] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0032] (1) The present invention fixes the formwork on the entire truss unit, and the truss unit is a stable steel structure with a high bearing capacity. The entire truss unit is used to support the formwork, thereby increasing the force-bearing capacity of the formwork. When the concrete has a large fluidity, the formwork is not easily deformed, which meets the requirements of pouring concrete from top to bottom.

[0033] (2) The present invention fixes the entire truss unit separately on the single steel plate wall, first installs the first connecting support truss and the second connecting support truss, then measures the distance between the first connecting support truss and the second connecting support truss, adjusts the processing size of the horizontal support truss, and completes the processing and manufacturing of the horizontal support truss, and then fixes the horizontal support truss between the first connecting support truss and the second connecting support truss to avoid the installation error of the fixed support 1 and the fixed support 2 that makes the entire truss unit unable to be installed.

[0034] (3) The present invention winds the rope of the lifting device around the fixed pulleys of the first lifting support and the second lifting support, and lifts the entire truss unit to the upper floor through the rope of the lifting device, and pours concrete layer by layer, thereby reducing the concrete pouring height, facilitating the dense molding of concrete, improving the quality of concrete pouring, and effectively improving the bearing capacity of the single steel plate wall exterior wall.

[0035] (4) In this application, the baffle and the entire truss unit are removed, and the formwork is removed at the same time, so that the poured concrete is exposed and other decorative components can be set on the outside of the concrete. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0056] like Figures 1 to 18 As shown in FIG, the construction method of pouring concrete on the outer side of the single steel plate wall of the present invention comprises the following steps:

[0057] a. According to the construction drawings and information model data, a steel plate wall 1 is obtained by processing, and then the steel plate wall 1 and the steel beam 2 are welded and fixed in a workshop to obtain an integrated steel member 3.

[0058] b. Use measuring instruments to adjust the horizontal and vertical position of the integrated steel member 3, then weld the integrated steel member 3 to the steel column 4. Simultaneously, weld the two adjacent sections of the integrated steel member 3 together to form a single steel plate wall. Then, weld L-shaped plates 7 to the upper and lower ends of the steel column 4. Wrap the single steel plate wall with a steel mesh, which is secured to the wall with tie bars.

[0059] c. Measure and record the installation errors of the steel column 4 and the steel beam 2, and feed the errors back into the construction drawings and the information model.

[0060] d. According to the measurement data and model information in step c, complete the processing and production of fixed support 1 5 and fixed support 2 6, then open through holes on fixed support 1 5 and fixed support 2 6, and weld connecting sleeves 8 in the through holes. The connecting sleeves 8 are provided with threaded holes 9, and then fix fixed support 1 5 to the set position of steel column 4, and fix fixed support 2 6 to the set position of steel beam 2.

[0061] e. The first connecting support truss 10 and the second connecting support truss 11 are obtained by processing steel pipes, and connecting plates 16 are welded on both sides of the first connecting support truss 10 and the second connecting support truss 11. The first connecting support truss 10 is positioned on the fixed support 1 5, and the second connecting support truss 11 is positioned on the fixed support 2 6. When positioning the first connecting support truss 10 and the second connecting support truss 11, according to construction requirements, spacers are set between the first connecting support truss 10 and the fixed support 1 5, and between the second connecting support truss 11 and the fixed support 2 6, so that the first connecting support truss 10 and the second connecting support truss 11 are at the same horizontal position, ensuring that the first connecting support truss 10 and the second connecting support truss 11 can be connected into an integral structure later.

[0062] A threaded connecting rod 35 is screwed into the connecting hole of the first connecting support truss 10, and the connecting rod 35 is screwed into the threaded hole 9 on the corresponding fixed support 1 5. Then, a threaded connecting rod 35 is screwed into the connecting hole of the second connecting support truss 11, and the connecting rod 35 is screwed into the threaded hole 9 on the corresponding fixed support 2 6 to fix the first connecting support truss 10 and the second connecting support truss 11 to avoid positional displacement of the entire truss unit in the later stage.

[0063] f. Measure the distance between the first connecting support truss 10 and the second connecting support truss 11, adjust the processing dimensions of the horizontal support truss 12, complete the processing and manufacture of the horizontal support truss 12 using steel pipes, and then fix the horizontal support truss 12 between the first connecting support truss 10 and the second connecting support truss 11. Then, fix the edge support truss 13 to the first connecting support truss 10. The edge support truss 13 is welded using steel pipes. The first connecting support truss 10, the second connecting support truss 11, the horizontal support truss 12, and the edge support truss 13 are all fixed with brackets 14. Adjacent brackets 14 are fixed with bolts to form the entire truss unit 19. This allows the steel components that make up the entire truss unit 19 to be detachably connected and recyclable, reducing costs.

[0064] g. Set the template 15 on the entire truss unit 19, and weld the template 15 and the connecting plate 16 to fix them.

[0065] h. Fix a baffle 32 to the entire truss unit 19. The formwork 15 and baffle 32 enclose a pouring space 20. Then, install a first lifting support 17 on the top of the first connecting support truss 10 and the second connecting support truss 11. Install a second lifting support 21 on the topmost fixed support 1 5 and fixed support 2 6. The second lifting support 21 and fixed support 1 5 are arranged correspondingly. Both the first lifting support 17 and the second lifting support 21 are equipped with fixed pulleys 18. Then, install a lifting device on the single steel plate wall, and wind the lifting device rope around the fixed pulleys 18 of the first lifting support 17 and the second lifting support 21. Then, install a grouting hopper 27 on the truss unit. The grouting hopper 27 is located above the pouring space 20.

[0066] The grouting hopper 27 installation steps specifically include:

[0067] (1) A first sliding beam 26 is fixed to the top of the entire truss unit 19 , and the first sliding beam 26 is arranged along the width direction of the single steel plate wall.

[0068] (2) The first sliding block 24 and the second sliding beam 23 are welded and fixed, and then the first sliding block 24 is slid onto the first sliding beam 26. At this time, the second sliding beam 23 is arranged along the length direction of the single steel plate wall.

[0069] (3) Connect and fix the grouting hopper 27 and the second sliding block 31: The grouting hopper 27 is welded with a fixing portion 1 29, and the second sliding block 31 is welded with a fixing portion 2 30. A connecting arm 28 is provided between the fixing portion 1 29 and the fixing portion 2 30. The connecting arm 28 and the fixing portion 1 29 are connected by a rotating shaft and a nut. The connecting arm 28 and the fixing portion 2 30 are connected by a rotating shaft and a nut, which can adjust the tilt angle of the grouting hopper 27. Slide the second sliding block 31 onto the second sliding beam 23.

[0070] (4) Slide the first sliding block 24 on the first sliding beam 26. After the adjustment is completed, turn the limit bolt 25 on the first sliding block 24 so that the limit bolt 25 presses against the first sliding beam 26. Then slide the second sliding block 31 on the second sliding beam 23. After the adjustment is completed, turn the limit bolt 25 on the second sliding block 31 so that the limit bolt 25 presses against the second sliding beam 23.

[0071] The grouting hopper 27 can be adjusted and limited along the width and length of the single steel plate wall, so that the concrete can quickly fill the entire pouring space 20, shortening the concrete pouring time.

[0072] When step h is completed, the limit plate 36 is fixed between the L-shaped plates 7 by connecting bolts, and a limit groove 37 is formed between the limit plate 36 and the steel column 4. When installing the baffle 32, the horizontal plate 33 and the vertical plate 34 are welded into a connecting frame, and then the baffle 32 is welded to the horizontal plate 33 of the connecting frame, and then the threaded rod 38 is welded on the inner side of the horizontal plate 33. According to the position of the threaded rod 38, a mounting hole is opened on the edge support truss 13, and then the threaded rod 38 of the connecting frame is inserted into the mounting hole. At the same time, the baffle 32 passes through the limit groove 37, and then the nut 39 is screwed into the threaded rod 38 and locked.

[0073] i. Grouting is performed into the pouring space 20 through the grouting hopper 27 to form a first concrete layer 40. A steel mesh is arranged in the first concrete layer 40 to increase the strength of the poured concrete.

[0074] j. Unscrew the connecting rods 35 of the first connecting support truss 10 and the second connecting support truss 11, and lift the entire truss unit 19 to the upper floor using the ropes of the lifting device. When the entire truss unit 19 is lifted, the baffle 32 moves upward in the limiting groove 37. The baffle 32 limits the entire truss unit 19 to the steel column 4 during the lifting process, preventing the truss unit from shaking during the lifting and causing damage to the poured concrete structure. The baffle 32 also applies force to the truss unit on the steel column 4, reducing the pulling force of the ropes of the lifting device and preventing damage to the ropes. Then, screw the connecting rod 35 into the connecting hole of the first connecting support truss 10 and screw it into the threaded hole 9 on the corresponding fixed support 1 5. Then, screw the connecting rod 35 into the connecting hole of the second connecting support truss 11 and screw it into the threaded hole 9 on the corresponding fixed support 2 6. Grout is poured into the casting space 20 through the grouting hopper 27 to form the second concrete layer 22. The second concrete layer 22 and the first concrete layer 40 form an integrated structure.

[0075] k. Repeat step j to complete the concrete pouring.

[0076] After step k is completed, mortar is applied to the pre-embedded areas of the fixed support 1 5 and the fixed support 2 6 in the concrete to ensure the integrity of the concrete pouring.

[0077] After the concrete pouring is completed, the entire truss unit 19 is lowered to the ground using the rope of the lifting device, the rope is removed, and then the baffle 32, the limit plate 36 and the entire truss unit 19 are removed, and then the fixed support 1 5, the fixed support 2 6 and the L-shaped plate 7 are cut.

[0078] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all included in the scope of protection of the present invention.
