Description

Technical Field

[0001] The present application relates to the field of building construction technology, and in particular to a shear wall structure for earthquake-resistant and energy-saving houses and a construction method thereof. Background Art

[0002] Prefabricated buildings are buildings assembled on-site using prefabricated components. They are characterized by rapid construction, minimal climatic constraints, and labor-saving features.

[0003] Currently, prefabricated wall panels are often used for shear wall assembly during prefabricated housing construction. Multiple prefabricated wall panels are pre-embedded with rebar at both ends of their length. During construction, the panels are hoisted sequentially onto the floor slab, leaving a gap between each pair. Workers then connect the pre-embedded rebar between adjacent panels using connecting rebar. The gaps are then filled with concrete using formwork, creating cast-in-place reinforced concrete columns that connect the adjacent prefabricated wall panels.

[0004] Regarding the above-mentioned related technologies, when connecting and fixing two adjacent prefabricated wall panels, workers are required to tie the connecting steel bars and the embedded steel bars and pour the concrete. The process of tying the steel bars and pouring the concrete is relatively cumbersome and time-consuming, which makes the construction efficiency of the shear wall low. Summary of the Invention

[0005] In order to improve the problem of low construction efficiency of shear walls, the present application provides a shear wall structure for earthquake-resistant and energy-saving houses and a construction method thereof.

[0006] On the one hand, the present application provides a shear wall structure for earthquake-resistant and energy-saving houses using the following technical solutions:

[0007] A shear wall structure for earthquake-resistant and energy-saving houses includes a plurality of prefabricated wall panels arranged at intervals, a positioning column fixed on the floor between each adjacent two prefabricated wall panels, a plurality of mounting tubes arranged at intervals along the height direction of the positioning column, a limiting rod slidably installed in the mounting tube, a plurality of insertion holes are arranged on the prefabricated wall panels corresponding to the mounting tubes, an adjustment mechanism is provided on the positioning column for driving the plurality of limiting rods to be inserted into the insertion holes, and a limiting member is provided on the positioning column for limiting the distance between the positioning column and the prefabricated wall panels.

[0008] By adopting the above technical solution, when constructing the shear wall, the staff will hoist the prefabricated wall panel on the floor slab, and then drive multiple limit rods to be synchronously inserted into the corresponding sockets through the adjustment mechanism, and then limit the distance between the prefabricated wall panel and the positioning column through the limit member, thereby realizing the rapid fixation of the prefabricated wall panel on the positioning column, saving the staff the trouble of operation and improving the construction efficiency of the shear wall.

[0009] Optionally, a through groove is provided on one end face of the positioning column, and the inner cavities of the multiple mounting cylinders are connected to the through groove. The adjustment mechanism includes an adjusting rod and multiple driving components, and the adjusting rod is slidably installed on the inner wall of the through groove; the multiple driving components correspond one-to-one to the multiple limiting rods, and when the adjusting rod slides and is inserted into the inner cavity of the through groove, the driving component drives the limiting rod away from one end of the positioning column and inserted into the socket.

[0010] By adopting the above technical solution, after the prefabricated wall panel is hoisted on the floor, the staff inserts the adjusting rod into the groove of the positioning column. The adjusting rod acts as a control component to drive the driving component to work, so that the driving component drives the limiting rod to be inserted into the socket, thereby realizing a quick connection between the prefabricated wall panel and the positioning column.

[0011] Optionally, the driving component includes:

[0012] A limiting sleeve and a sliding sleeve are arranged on the peripheral side of one end of the limiting rod close to the adjusting rod;

[0013] a locking member, disposed in the mounting cylinder and used to lock the sliding of the limiting sleeve;

[0014] A limit spring is compressed and sleeved around the limit rod, with one end fixedly connected to the limit sleeve and the other end fixedly connected to the limit sleeve;

[0015] A first insertion rod is slidably mounted in the mounting tube, a limiting groove is provided on the circumference of the limiting rod, a first cone head is fixedly provided at one end of the first insertion rod, and the first cone head is detachably inserted into the limiting groove, and the inclined surface of the head of the first cone head is slidably fitted with the inner wall of the limiting groove;

[0016] The sliding rod is slidably installed in the mounting tube, and one end of it away from the adjusting rod is elastically connected to the inner wall of the mounting tube, and the opposite end extends through the mounting tube, and one side of the sliding rod is slidably fitted with an end face of the first insertion rod away from the limit rod, and a first slot is provided on the sliding rod corresponding to the first insertion rod, and the distance between the side face of the first insertion rod facing the slot and the inner wall of the first slot facing the slot is equal to the length of one end of the sliding rod extending out of the mounting tube.

[0017] By adopting the above technical solution, when the adjusting rod is inserted into the through slot, the adjusting rod presses the sliding rod, and then the sliding rod slides away from the adjusting rod, so that the first slot on the sliding rod is opposite the first insertion rod; at this time, the side wall of the sliding rod no longer limits the sliding of the first insertion rod, and then under the action of the restoring force of the limit spring, the limit rod slides and inserts into the insertion hole. In this process, the sliding limit rod also pushes the first insertion rod to slide and insert into the first slot, and then the first insertion rod no longer locks the sliding of the limit rod, and the first insertion rod is inserted into the first slot to lock and position the sliding rod.

[0018] Optionally, the locking member is a second insertion rod slidably mounted in the mounting tube, a second cone head is fixed to one end of the second insertion rod facing the limiting rod, a limiting hole is formed on the circumference of the limiting sleeve for the second insertion rod to pass through, and the diameter of the limiting hole gradually increases from the inner wall of the limiting sleeve to the outer wall of the limiting sleeve;

[0019] The outer wall of the limit rod is provided with a long hole for the second cone head to be inserted into, and the extension direction of the long hole is consistent with the length direction of the limit rod. The long hole is inclined away from an inner wall of the first cone head, and the distance between the inclined surface and the first insertion rod gradually increases along the direction from the center line of the limit rod to the opening of the long hole. When the limit rod is inserted into the insertion hole, the inclined surface pushes against the inclined surface of the head of the second cone head.

[0020] By adopting the above technical solution, when the limit rod is inserted into the insertion hole, the inclined surface pushes the inclined surface of the head of the second cone head, so that the second cone head is pushed and slides away from the limit rod, and the end of the second cone head slides to the limit hole of the limit sleeve, and then the limit sleeve slides in the direction toward the positioning column under the action of the restoring force of the limit spring, and the sliding limit sleeve pushes the head of the second insertion rod through the inner wall of the limit hole to separate the second insertion rod from the limit sleeve, and then the limit sleeve is quickly inserted into the installation hole under the action of the restoring force of the limit spring, thereby realizing the rapid locking of the adjusting rod on the positioning column, so that the positioning column, adjusting rod, limit rod and prefabricated wall panel are connected as one.

[0021] Optionally, an elastic pad is fixedly provided on the circumference of one end of the limiting rod away from the limiting sleeve, and the outer periphery of the elastic pad can be detachably fitted to the inner circumferential wall of the insertion hole.

[0022] By adopting the above technical solution, the limit rod and the inner wall of the socket are elastically connected by an elastic pad, so that an installation adjustment gap is provided between the prefabricated wall panel and the limit rod, so that during an earthquake, the elastic pad can be used to reduce vibration and buffer the space between two adjacent prefabricated wall panels, thereby improving the seismic performance of the shear wall.

[0023] Optionally, positioning holes are opened at the bottom of the prefabricated wall panels, and fixing columns are fixed on the floor panels corresponding to the positioning holes, and the surrounding sides of the fixing columns are covered with an elastic layer.

[0024] By adopting the above technical solution, fixed columns are set to pre-position the prefabricated wall panels hoisted to the floor slabs, thereby improving the connection stability between the prefabricated wall panels and the floor slabs and making it easier for workers to fix the connection between the prefabricated floor slabs and the positioning columns.

[0025] Optionally, the diameter of the fixing column gradually increases from the upper end of the fixing column to the lower end of the fixing column.

[0026] By adopting the above technical solution, the top of the fixed column is in a frustum shape, so that when the staff uses the lifting equipment to lift the prefabricated wall panel to the fixed column, the prefabricated wall panel can be conveniently plugged and assembled with the fixed column.

[0027] Optionally, the limiting member is a detachable pressing plate arranged on the positioning column, a fitting groove is provided on a side of the prefabricated wall panel close to the pressing plate, and an insert block adapted to the fitting groove is fixed to one end of the pressing plate.

[0028] By adopting the above technical solution, the fitting groove of the prefabricated wall panel is plugged into and adapted with the plug-in block on the pressure plate, so that the prefabricated wall panel and the pressure plate are firmly connected, and then the prefabricated wall panel and the positioning column are connected to each other, thereby improving the connection stability between the prefabricated wall panel and the positioning column.

[0029] Optionally, a pull rod passing through the positioning column, the adjusting rod and the pressure plate is provided on the positioning column, and locking nuts are threadedly assembled on both ends of the pull rod.

[0030] By adopting the above technical solution, a pull rod and a locking nut are provided so that the pressure plate is fastened and locked on the positioning column.

[0031] On the other hand, the present application provides a construction method for a shear wall structure of an earthquake-resistant and energy-saving house, which comprises the following steps:

[0032] Step 1: Hoist the prefabricated wall panels so that the fixing columns are plugged into the positioning holes on the prefabricated wall panels;

[0033] Step 2: Insert the adjusting rod into the inner wall of the slot so that the adjusting rod presses the sliding rod;

[0034] Step 3: Adjust the pressing plate to insert the insert block on the pressing plate into the fitting groove on the prefabricated wall panel;

[0035] Step 4: Insert the tie rod into one side of the pressure plate, then tighten the lock nuts at both ends of the tie rod. By adopting the above technical solution, the prefabricated pressure plate is first pre-positioned on the floor slab using the positioning columns. Then, the adjustment mechanism is used to simultaneously insert multiple limit rods into the sockets of the prefabricated wall panels to achieve the mutual connection between the prefabricated wall panels and the positioning columns. The pressure plate is then assembled on the positioning columns to ensure a stable connection between the positioning columns and the prefabricated wall panels.

[0036] In summary, this application includes at least one of the following beneficial technical effects:

[0037] 1. The prefabricated pressure plate is first pre-positioned on the floor slab through the positioning columns. Then, the multiple limit rods are synchronously inserted into the sockets of the prefabricated wall panels through the adjustment mechanism to achieve the mutual connection between the prefabricated wall panels and the positioning columns. The pressure plate is then assembled on the positioning columns to ensure that the positioning columns and the prefabricated wall panels are stably connected as one.

[0038] 2. When the adjusting rod is inserted into the slot, the adjusting rod presses the sliding rod, and then the sliding rod slides away from the adjusting rod, so that the first slot on the sliding rod is aligned with the first insertion rod. Then, under the restoring force of the limit spring, the limit rod slides and pushes the first insertion rod away, so that the limit rod slides into the insertion hole;

[0039] 3. When the limit rod is inserted into the socket, the inclined surface pushes the inclined surface of the head of the second cone head, so that the second cone head is pushed and slides away from the limit rod. The sliding limit sleeve pushes the head of the second insertion rod through the inner wall of the limit hole to separate the second insertion rod from the limit sleeve. Then, the limit sleeve is quickly inserted into the mounting hole under the action of the restoring force of the limit spring, thereby realizing the rapid locking of the adjusting rod on the positioning column.

[0045] The following is combined with Figure 1-4 This application is described in further detail.

[0046] The embodiment of the present application discloses a shear wall structure for earthquake-resistant and energy-saving houses. Figure 1 and Figure 2 The shear wall structure for earthquake-resistant and energy-saving houses includes a plurality of prefabricated wall panels 1 arranged at intervals. A positioning column 2 is fixedly connected between each adjacent prefabricated wall panels 1 on the floor slab by expansion bolts. A plurality of mounting tubes 3 are arranged at intervals along the height direction of the positioning column 2 on both sides of the prefabricated wall panel 1. The plurality of mounting tubes 3 are all arranged horizontally and their length direction is consistent with the length direction of the prefabricated wall panel 1. A limit rod 4 is slidably installed on the inner wall of the mounting tube 3 along the length direction of the mounting tube 3. In order to achieve a quick connection between the prefabricated wall panel 1 and the positioning column 2, a socket 11 is opened on the side wall of the prefabricated wall panel 1 facing the positioning column 2, corresponding to each mounting tube 3. The positioning column 2 is provided with an adjustment mechanism for driving the plurality of limit rods 4 to be synchronously inserted into the socket 11. The positioning column 2 is provided with a limit member 5 for limiting the distance between the positioning column 2 and the prefabricated wall panel 1.

[0047] Reference Figure 1 and Figure 2 In this embodiment, the limiting member 5 is a fixed column 51 vertically fixed to the floor slab. The fixed column 51 is in the shape of a cone, and the diameter of the fixed column 51 gradually increases from the upper end of the fixed column 51 to the lower end of the fixed column 51. The circumference of the fixed column 51 is covered and fixed with a buffer layer 52 made of a corrosion-resistant rubber sheet or foam board. The bottom of the prefabricated wall panel 1 is provided with a positioning hole for the fixed column 51 to be inserted. When the staff hoist the prefabricated wall panel 1 to the floor slab using lifting equipment such as a tower crane or a truck crane, the staff inserts the prefabricated wall panel 1 into the fixed column 51 so that the prefabricated wall panel 1 is pre-fixed to the floor slab through the fixed column 51, so that the staff can quickly connect the prefabricated wall panel 1 to the positioning column 2.

[0048] In other embodiments, the positioning member 5 is a positioning platform fixed to the floor slab, with a slide groove defined on the upper surface of the positioning platform and a notch connected to the slide groove defined on the side of the positioning platform facing the interior. A slider is fixed to the bottom of the prefabricated wall panel 1. When installing the prefabricated wall panel 1, the slider on the prefabricated wall panel 1 slides along the notch into the slide groove, thereby pre-positioning the prefabricated wall panel 1 on the positioning platform.

[0049] Reference Figure 3 and Figure 4 The positioning column 2 is rectangular, with its length aligned with the length of the prefabricated wall panel 1. A through-slot 21 is defined on one end face of the positioning column 2 in the width direction, with the inner cavities of the multiple mounting cylinders 3 communicating with the through-slot 21. The adjustment mechanism includes an adjustment rod 61 and multiple drive assemblies. The adjustment rod 61 slides into the through-slot 21 in a direction parallel to the width of the positioning column 2, with the circumference of the adjustment rod 61 engaging with the inner circumferential wall of the through-slot 21.

[0050] An elastic pad 43 is fixedly mounted around the end of the limiting rod 4 away from the through-slot 21. The outer periphery of the elastic pad 43 is detachably attached to the inner wall of the insertion hole 11. Multiple drive assemblies correspond to multiple limiting rods 4. When the adjustment rod 61 slides into the inner cavity of the through-slot 21, the drive assembly drives the end of the limiting rod 4 away from the positioning column 2 to insert into the insertion hole 11, thereby achieving a quick connection between the limiting rod 4 and the prefabricated wall panel 1.

[0051] Reference Figure 3 and Figure 4 The drive assembly includes a limit sleeve 62, a locking member, a limit spring 64, a first insertion rod 65, and a sliding rod 66. The limit sleeve 62 is slidably mounted on the circumference of one end of the limit rod 4 close to the positioning column 2. The locking member is disposed in the mounting tube 3 and is used to lock the sliding of the limit sleeve 62. The limit spring 64 is compressed and mounted on the circumference of the limit rod 4. One end of the limit spring 64 is fixedly connected to the limit sleeve 62, and the other end is fixedly connected to the limit rod 4. A guide column is fixed on the inner wall of the mounting tube 3, and a guide hole is opened in the guide column. The first insertion rod 65 is slidably mounted in the mounting tube 3 through the guide column and slides along a direction perpendicular to the length of the limit rod 4.

[0052] Reference Figure 3 and Figure 4 In order to limit the installation position of the limit rod 4 by the first insertion rod 65, a limit groove 41 is provided on the circumferential side of the limit rod 4, and the opening of the limit groove 41 is in the shape of a trumpet; a first cone head 651 is integrally formed at one end of the first insertion rod 65 in the length direction, and the first cone head 651 can be detachably inserted into the limit groove 41, and the inclined surface of the head of the first cone head 651 can be detachably slidably fitted with the inner wall of the limit groove 41.

[0053] To adjust the installation position of the first insertion rod 65 and release the positional restriction imposed by the first insertion rod 65 on the limiting rod 4, a sliding rod 66 is slidably mounted within the mounting tube 3, with its sliding direction aligned with the longitudinal direction of the mounting tube 3. Its end distal to the through-slot 21 is elastically connected to an inner wall of the mounting tube 3. This elastic connection can be achieved by providing a connecting spring between the longitudinal end of the sliding rod 66 and the inner wall of the mounting tube 3. Alternatively, a highly elastic rubber pad is bonded to one longitudinal end of the sliding rod 66, with the end distal to the adjustment rod 61 abutting against the inner wall of the mounting tube 3. The end of the sliding rod 66 proximal to the through-slot 21 extends through the mounting tube 3 and into the through-slot 21. The end extending into the through-slot 21 is spherical. This spherical configuration of one end of the sliding rod 66 facilitates the subsequent insertion of the adjustment rod 61 into the positioning column 2 to press against the end of the sliding rod 66.

[0054] In this embodiment, a side surface of the slide bar 66 slides in contact with an end surface of the first insertion rod 65 facing away from the stop rod 4. A first slot 661 is defined on the slide bar 66 corresponding to the first insertion rod 65. The first slot 661 is offset from the first insertion rod 65 along the length of the slide bar 66. When the slide bar 66 is not actuated, the distance between the side surface of the first insertion rod 65 facing the through-slot 21 and the inner wall of the first slot 661 facing the through-slot 21 is equal to the length of the end of the slide bar 66 extending into the through-slot 21.

[0055] After the staff inserts the adjustment rod 61 into the through slot 21, the outer wall of the adjustment rod 61 presses against the ball end of the slide rod 66. The slide rod 66 is then pressed and slides away from the adjustment rod 61, causing the first slot 661 on the slide rod 66 to face the first insertion rod 65. The sidewall of the slide rod 66 then no longer restricts the sliding movement of the first insertion rod 65. Then, under the restoring force of the limit spring 64, the limit rod 4 slides and pushes the first insertion rod 65, forcing the first insertion rod 65 into the first slot 661. This forces the first insertion rod 65 into the first slot 661, locking the slide rod 66 in place. The restoring force of the limit spring 64 then pushes the limit rod 4 into the socket 11 of the prefabricated wall panel 1, achieving a quick connection between the positioning column 2 and the prefabricated wall panel 1.

[0056] Reference Figure 3 and Figure 4 In this embodiment, the locking member is a second rod 63 slidably mounted within the mounting tube 3. The length of the second rod 63 is perpendicular to that of the mounting tube 3, and a second conical head 631 is integrally formed on the end of the second rod 63 facing the limiting rod 4. A limiting hole 621 is formed on the circumference of the limiting sleeve 62 for the second rod 63 to pass through, and the diameter of the limiting hole 621 gradually increases from the inner wall of the limiting sleeve 62 to the outer wall of the limiting sleeve 62. An elongated hole 42 is formed on the outer wall of the limiting rod 4 for the second conical head 631 to insert into. The elongated hole 42 extends in the same direction as the length of the limiting rod 4. An inner wall of the elongated hole 42, away from the first conical head 651, is inclined, and the distance between the inclined surface and the first rod 65 gradually increases from the centerline of the limiting rod 4 to the opening of the elongated hole 42.

[0057] In other embodiments, the limiting member 5 is a locking bolt, the locking bolt thread passes through the outer wall of the mounting tube 3, and a threaded hole for the locking bolt threaded connection is opened on the outer peripheral side of the limiting sleeve 62. The limiting sleeve 62 can be locked on the mounting tube 3 by the threaded cooperation between the locking bolt and the threaded hole.

[0058] Correspondingly, a second slot 662 is defined around the periphery of the slide bar 66, which slidably engages with the end face of the second insertion rod 63 facing away from the stop rod 4. A mounting hole 611 is defined around the periphery of the adjustment rod 61 for receiving the stop sleeve 62. When the stop rod 4 is not inserted into the insertion hole 11, the second slot 662 and the second insertion rod 63 are offset along the length of the slide bar 66. When the adjustment rod 61 is inserted into the insertion hole 11, the adjustment rod 61 pushes the slide bar 66, and then the opening of the second slot 662 on the slide bar 66 faces the second insertion rod 63, causing the inclined surface of the slide bar 66 to press against the inclined surface of the head of the second cone 631.

[0059] After the limiting rod 4 is inserted into the insertion hole 11, the inclined surface on the limiting rod 4 pushes against the inclined surface of the head of the second cone 631, causing the second cone 631 to slide away from the limiting rod 4 under the force of the inclined surface. This allows the tip of the second cone 631 to slide into the limiting hole 621 of the limiting sleeve 62, and the second insertion rod 63 is inserted into the second slot 662. The limiting sleeve 62 then slides toward the positioning column 2 under the restoring force of the limiting spring 64. The sliding limiting sleeve 62 pushes the head of the second insertion rod 63 through the inner wall of the limiting hole 621, causing the second insertion rod 63 to slide away from the limiting sleeve 62. The limiting sleeve 62 then quickly inserts into the mounting hole 611 under the restoring force of the limiting spring 64, quickly locking the adjustment rod 61 to the positioning column 2, thereby connecting the positioning column 2, the adjustment rod 61, the limiting rod 4, and the prefabricated wall panel 1 as a whole.

[0060] Reference Figure 1 and Figure 2 After the limiting sleeve 62 is inserted into the mounting hole 611 of the adjusting rod 61 under the restoring force of the limiting spring 64, in order to improve the connection stability between the prefabricated wall panel 1 and the positioning column 2, two detachable pressure plates 7 are provided on the positioning column 2. The two pressure plates 7 are symmetrically arranged on both sides of the thickness direction of the prefabricated wall panel 1. Insert blocks 71 are integrally formed at both ends of the pressure plates 7 in the length direction and on the side close to the prefabricated wall panel 1.

[0061] Two engaging grooves 12 are respectively formed on both end faces of the prefabricated wall panel 1 in the thickness direction. The two engaging grooves 12 on one end face are spaced apart along the length direction of the prefabricated wall panel 1. Shock-absorbing pads 13 are bonded to the inner walls of the engaging grooves 12. The engaging grooves 12 are adapted to the insert blocks 71. During use, the engaging grooves 12 of the insert prefabricated wall panel 1 are plugged and adapted to the insert blocks 71 on the pressure plate 7, thereby firmly connecting the prefabricated wall panel 1 and the pressure plate 7, and further connecting the prefabricated wall panel 1 and the positioning column 2, thereby improving the stability of the connection between the prefabricated wall panel 1 and the positioning column 2.

[0062] Reference Figure 1 and Figure 2To enhance the installation stability of the pressure plate 7, a tie rod 8 is provided on the positioning column 2. Through holes are provided on one side of the positioning column 2 in the width direction, on the side wall of the adjustment rod 61 in the width direction, and on the side wall of the pressure plate 7 in the thickness direction. After the insert 71 on the pressure plate 7 is inserted into the fitting groove 12, the staff adjusts the tie rod 8 so that it passes through the pressure plate 7, the positioning column 2, and the adjustment rod 61 along the through hole. The staff then installs lock nuts 81 on both ends of the tie rod 8 along the length direction and presses the lock nuts 81 against the surface of the pressure plate 7, thereby securing the pressure plate 7 to the positioning column 2.

[0063] The implementation principle of the shear wall structure for earthquake-resistant and energy-saving houses in the embodiment of the present application is as follows: the staff first fixes the positioning column 2 and the fixing column 51 to the floor slab through connectors such as expansion bolts, and then the staff hoist the prefabricated wall panel 1 so that the prefabricated wall panel 1 is pre-positioned on the floor slab through the cooperation of the fixing column 51 and the positioning hole. The staff then inserts the adjustment rod 61 into the through groove 21 of the positioning column 2, and the adjustment rod 61 presses the slide rod 66, causing the slide rod 66 to slide away from the adjustment rod 61; under the restoring force of the limit spring 64, the limit rod 4 slides and pushes the first insertion rod 65, which is pushed to slide and insert into the first slot 661, and the limit rod 4 slides into the socket 11 of the prefabricated wall panel 1. At this time, the limit spring 64 is still in a compressed state, and the positioning column 2 and the prefabricated wall panel 1 are connected as one.

[0064] After the limiting rod 4 is inserted into the insertion hole 11, the inclined surface on the limiting rod 4 pushes against the inclined surface of the head of the second cone 631, causing the second cone 631 to slide away from the limiting rod 4 under the push of the inclined surface. Then, the limiting sleeve 62 slides toward the positioning column 2 under the continuous restoring force of the limiting spring 64. During the sliding process of the limiting sleeve 62, the inner wall of the limiting hole 621 pushes the head of the second insertion rod 63, separating the second insertion rod 63 from the limiting sleeve 62. Then, the installation tube 3 is quickly inserted into the installation hole 611 under the restoring force of the limiting spring 64, achieving a quick locking of the adjustment rod 61 on the positioning column 2, thereby connecting the positioning column 2, the adjustment rod 61, the limiting sleeve 62, the limiting rod 4, and the prefabricated wall panel 1 as a whole.

[0065] Then the staff inserts the plug 71 on the pressure plate 7 into the fitting groove 12, and then locks the pressure plate 7 to the positioning column 2 through the pull rod 8 and the locking bolt, and injects foam glue or quick-setting insulation filler into the gap between the prefabricated wall panel 1 and the floor slab, and the gap between the prefabricated wall panel 1 and the positioning column 2 to complete the installation and forming of the shear wall.

[0066] The present application also discloses a method for constructing a shear wall structure for an earthquake-resistant and energy-saving house. The method comprises the following steps:

[0067] Step 1: Hoist the prefabricated wall panel 1 so that the fixing column 51 is plugged into the positioning hole on the prefabricated wall panel 1;

[0068] Step 2: Insert the adjusting rod 61 into the inner wall of the through slot 21 so that the adjusting rod 61 presses the sliding rod 66;

[0069] Step 3: Adjust the pressing plate 7 so that the insert block 71 on the pressing plate 7 is inserted into the fitting groove 12 on the prefabricated wall panel 1;

[0070] Step 4: Insert the pull rod 8 into one side of the pressure plate 7 , and then tighten the lock nuts 81 at both ends of the pull rod 8 .

[0071] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
