Description

Technical Field

[0001] This invention relates to an external wall scaffolding lifting guide rail mechanism, lifting method, and wall nail positioning method, belonging to the field of building construction technology. Background Technology

[0002] Scaffolding is an essential temporary construction facility in the process of building construction, and it is directly related to the safety and efficiency of construction.

[0003] like Figure 1-4 As shown, in a typical type of residential and commercial high-rise building, the exterior of the third or fourth floor and above consists of vertical walls that go straight up and down. During construction, the main building structure 7, consisting of columns 701, beams, and floor slabs 702 (which serve as both the roof of the next floor and the floor of the floor above), is built from bottom to top. Then, the exterior walls and facades are enclosed from bottom to top or top to bottom. A characteristic of this type of building structure is that the outer perimeter of the floor slabs 702 on the third or fourth floor and above is on the same vertical plane and equally spaced, while the columns 701 are located inside the outer perimeter of the floor slabs 702.

[0004] To improve the construction efficiency of the aforementioned high-rise building, the existing technology designs the exterior wall scaffolding 6 as a whole scaffolding system that surrounds and attaches to the outer perimeter of the completed building structure. This exterior wall scaffolding 6 rises as the building height increases and can be moved vertically around the building structure after completion for further use in the cladding and finishing of the exterior walls. The exterior wall scaffolding 6 includes inner columns 601, outer columns 602, and tracks 605. The inner columns 601 are attached to the outer perimeter of the building structure's floor slabs 702 via the tracks 605. A platform 603 for workers to stand and walk on is provided between the inner columns 601 and the outer columns 602. A safety net 604 is installed on the outer columns 602. A wall-mounted support 606 is provided on the outer periphery of the floor slab 702. The wall-mounted support 606 is used for the vertical movement of the track 605 and for height positioning and horizontal restraint of the track. The wall-mounted support 606 has a base, supporting components for positioning the track 605, and complex anti-fall and anti-overturning mechanisms. The exterior wall scaffolding 6 includes a lower part and an upper part. The track 605 has a fixed section at the bottom and a temporary fixed section at the top. The fixed section of the track is fixed to the lower part of the exterior wall scaffolding 6. The exterior wall scaffolding 6 also has several electric hoists (generally electric hoists, not shown in the figure) that uniformly execute lifting commands.

[0005] The application principle of the aforementioned exterior wall scaffolding 6 is as follows: The fixed section of the track 605 is fixed to the lower part of the exterior wall scaffolding 6. The exterior wall scaffolding 6 is temporarily fixed to the outer perimeter of the three floor slabs 702 on the top of the already constructed three-story building via wall-mounted supports 606. The upper part of the exterior wall scaffolding 6 extends upwards to the height of the next floor to be constructed. After the workers construct the next floor using the upper platform 603 of the exterior wall scaffolding 6, they fix the wall-mounted supports 606 to the outer perimeter of the newly constructed floor slab 702 by drilling holes. Then, a temporary fixed section of the track 605, which cooperates with the wall-mounted supports 606, is installed above the fixed section of the track 605, connecting the temporary fixed section of the track 605 with the fixed section. Then, under the lifting force provided by several electric lifts that uniformly execute lifting commands, the exterior wall scaffolding 6 is raised one floor. After the raising is completed, the temporary fixed section of the track 605 is dismantled. After the floor slab 702 of the next floor is constructed, the above operation is repeated until the entire main structure of the building is completed. After the main structure of the building is completed, the external wall scaffolding 6 is lowered layer by layer in the reverse manner of raising it upwards, so as to complete the enclosure of the external wall and the decoration of the external wall surface from top to bottom.

[0006] The existing application of external wall scaffolding 6 has the following three problems:

[0007] 1. The wall-mounted support 606 used for track lifting and positioning is exposed on the outer periphery of the floor slab 702. When concrete pouring is carried out on the upper floor, concrete slurry inevitably splashes onto the wall-mounted support 606 and solidifies in a short time. This can easily cause the complex rotating mechanism of the wall-mounted support 606 to jam and fail, resulting in the inability to achieve the function of supporting and limiting the track. The number of wall-mounted supports used on the outer wall scaffolding 6 attached to the outer periphery of a building can reach hundreds. Each one must be carefully checked before each lifting and lowering, which requires a lot of manpower.

[0008] 2. It is difficult to determine the locking point of the external wall scaffolding track on the newly built floor slab 702 on the upper floor. The wall-mounted supports used for track lifting and locking are drilled and installed after the newly built floor slab 702 on the upper floor is built. Each wall-mounted support 606 requires at least three wall holes to be drilled for screwing in the fixing bolts. Due to the strong vibration force of the drilling electric drill, it is very easy to cause the drilling position to deviate, making it difficult to achieve accurate positioning of the wall-mounted support 606. This not only makes it difficult for the installation of the wall-mounted support 606 to meet the high-precision installation requirements, but also consumes a lot of time.

[0009] 3. The temporary fixed section of the track needs to be installed and removed every time it is raised or lowered, resulting in a huge workload;

[0010] 4. The structure of the wall-mounted support is too complex. Summary of the Invention

[0011] The problem this invention aims to solve is: how to prevent the device used for rail lifting and positioning from being adhered to by splashed concrete slurry.

[0012] To address the aforementioned problems, the technical solution proposed in this invention is: an external wall scaffolding lifting guide rail mechanism, comprising a guide rail, a locking support, and locking wall nails horizontally fixed to the outer perimeter of the concrete floor slab. The guide rail is fixed to the inner column of the external wall scaffolding and is divided into a lower locking fixing section and an upper positioning guide section. The guide rail has an internal space that is open vertically, and the front side facing the wall has a slot for the outer section of the locking wall nail to extend into the internal space and slide up and down. The locking support is located in the internal space of the locking fixing section of the guide rail and can be combined with the locking wall nail to temporarily fix the external wall scaffolding at a certain height.

[0013] The outer end of the positioning wall nail has a limiting handle, and its inner section has an external thread. The positioning wall nail also has a threaded sleeve that mates with the external thread of its inner section and is embedded in the concrete of the floor slab. The outer periphery of the threaded sleeve has raised textures to prevent axial movement.

[0014] The inner space of the guide rail has a vertical partition, which divides the inner space into a front vertical locking space and a rear anti-tilting limiting space. The partition has a second slot parallel to the first slot, which allows the locking wall nail to pass through and slide up and down. The outer end of the locking wall nail passes through the vertical locking space and enters the anti-tilting limiting space. The limiting handle at the outer end is located in the anti-tilting limiting space, and the diameter of the limiting handle is greater than the width of the second slot. The locking support is located in the vertical locking space.

[0015] The positioning support includes a slotted seat plate, a rotating shaft, and a support block. The slotted seat plate has an installation slot. The two ends of the rotating shaft are respectively installed on the slot walls on both sides of the installation slot. The support block is installed in the installation slot through the rotating shaft and can rotate around the rotating shaft. The lower part of the support block below the rotating shaft has a positioning notch that opens to the outside. The upper inner side of the support block above the rotating shaft has a tension spring between it and the bottom wall of the installation slot. The slotted seat plate is fixed to one side of the positioning space. When the outer side of the support block is in a vertical state, it is close to the slots 1 and 2. When the lower part of the support block is not pressed, the tension spring causes the lower part of the support block to pop out of the installation slot, so that the positioning wall nails passing through the slots 1 and 2 can be locked into the positioning notch, preventing the external wall scaffolding from falling.

[0016] The lower side of the notch of the support block to the lower end of the support block is an arc-shaped bidirectional guide surface. When the positioning support rises with the external wall scaffolding, the positioning wall nail stuck in the positioning notch can slide down from the upper part of the bidirectional guide surface from the positioning notch, and press the lower part of the support block into the mounting groove during the downward sliding process; when the positioning support falls with the external wall scaffolding, the positioning wall nail can slide up from the lower part of the bidirectional guide surface, and press the lower part of the support block into the mounting groove during the upward sliding process.

[0017] The locking support also includes a reverse closing tongue plate. A vertical mounting groove is provided in the middle of the bidirectional guide surface. One end of the reverse closing tongue plate is installed in the mounting groove through a rotating shaft and can rotate up and down around the rotating shaft. The tip of the reverse closing tongue plate can rotate upward to overlap the outer side of the support block above the locking notch, thus closing the locking notch. A torsion spring is provided between the rotating shaft and the reverse closing tongue plate. When no external force is applied, the torsion spring keeps the reverse closing tongue plate in an oblique outward and downward posture and forms an angle with the lower part of the bidirectional guide surface. When an external force is applied, the reverse closing tongue plate can rotate upward or downward.

[0018] The external wall scaffolding lifting guide rail mechanism also includes a wall nail locator; the guide rail has a mounting base plate, and the top of the positioning guide section of the guide rail has a compensating guide rail with the same structure as the guide rail that can slide up and down on the mounting base plate. The wall nail locator is hinged to the mounting base plate at the junction of the compensating guide rail and the positioning guide section via a hinge shaft. When the compensating guide rail slides upward, the wall nail locator can rotate around the hinge shaft into the gap between the compensating guide rail and the positioning guide section.

[0019] The wall nail locator has a large-diameter hole on the rear side that accommodates a limiting handle for locking the wall nail, and a small-diameter hole on the front side that connects the large-diameter hole and the front side of the wall nail locator. The diameter of the small-diameter hole is only large enough to allow the inner and outer sections of the locking wall nail to pass through.

[0020] A method for raising and lowering external wall scaffolding using an external wall scaffolding lifting guide rail mechanism, wherein raising the external wall scaffolding to one floor includes the following steps:

[0021] A1. Fix the positioning wall nails on the newly built floor slab of the next floor, and make the outer section of the positioning wall nails located in the inner space of the guide rail positioning guide section, so that the limiting handle is located in the anti-tilting limiting space of the inner space.

[0022] A2. Under the lifting force provided by the lifting mechanism, the external wall scaffolding rises, causing the wall nails of each floor in the supported state to slide down from the notches of the support blocks of the supported supports in the supported state.

[0023] A3. As the exterior wall scaffolding continues to rise, when the wall nails in the upper floor slide down to the outer side of the support block of the support that rises from the lower floor and enter the gap, the exterior wall scaffolding stops rising.

[0024] A4. The lifting mechanism releases the force on the external wall scaffolding, and under the action of gravity, the support block of the external wall scaffolding presses against the locking wall nail that enters the locking notch through the upper side of the locking notch;

[0025] Lowering the exterior wall scaffolding to one floor involves the following steps:

[0026] B1. Raise the external wall scaffolding, allowing the wall nails in the support position of each floor to slide down from the notch of the support block of the support position to below the support block, and stop the external wall scaffolding from rising.

[0027] B2. Lower the external wall scaffolding, and the locking wall nail slides upward along the lower part of the bidirectional guide surface of the support block that has just come out. After contacting the reverse closing tongue plate, the reverse closing tongue plate is forced to rotate upward to seal the locking notch, so that the locking wall nail slides upward past the support block.

[0028] B3. Continue to lower the exterior wall scaffolding until each support is close to the wall nail of the next floor. Then, stop lowering the scaffolding when the wall nail of the next floor slides upward past the reverse closing tongue plate of the support block to close the notch.

[0029] B4. Raise the exterior wall scaffolding, and when the wall nails of the next floor slide down to the positioning gap as described in method A3, stop raising the exterior wall scaffolding.

[0030] B5. Following the method in A4, press the support block onto the wall nail in the notch through the upper side of the notch.

[0031] A method for positioning wall nails using a wall nail locator includes the following steps:

[0032] C1. Before pouring the next floor slab, slide the compensating guide rail upwards;

[0033] C2. Rotate the wall nail locator around the hinge axis into the gap between the compensating guide rail and the positioning guide section;

[0034] C3. Drill template holes in the template through the large-diameter holes and small-diameter holes of the wall nail locator;

[0035] C4. Rotate the wall nail locator in the opposite direction around the hinge axis until there is an operating gap between the compensation guide rail and the positioning guide section.

[0036] C5. Enlarge the holes in the template;

[0037] C6. Pass the inner section of the wall nail with external threads through the large diameter hole, small diameter hole and template hole on the template in sequence. The small diameter hole limits the posture of the wall nail. Screw the threaded sleeve with anti-slip texture on the inner section of the wall nail.

[0038] C7. When pouring the upper floor slab, the threaded sleeve is poured into the concrete;

[0039] C8. After the concrete has hardened, unscrew the wall nails from the threaded sleeve and remove the formwork;

[0040] C9. Re-screw the retaining wall nail into the threaded hole of the threaded sleeve.

[0041] Beneficial effects: The positioning support, which serves as a lifting and positioning device, is set in the inner space of the guide rail, which can completely prevent concrete slurry from splashing onto the positioning support when the upper floor slab is poured, ensuring that all moving parts of the positioning support can work normally.

[0042] Meanwhile, a wall nail locator is installed above the guide rail. During the pouring of the previous floor slab, it is positioned and a threaded hole is left for the inner section of the wall nail to be screwed in. This enables precise positioning of the threaded hole, allowing the wall nail to be screwed in directly during application. This ensures that the wall nail is not only accurately positioned on the outer perimeter of the floor slab, but also installed very quickly. Since dozens or even hundreds of wall nails need to be installed to raise the external wall scaffolding to one floor, a significant amount of installation time is saved, thereby significantly improving the work efficiency of moving the external wall scaffolding.

The diagram shows that during the process of the locking support rising with the external wall scaffolding, the locking notch of its support block is aligned with the locking wall nail. Under the action of the tension spring, the lower part of the support block pops outward, and the locking wall nail enters the locking notch of the support block. The locking support stops rising with the external wall scaffolding.

Detailed Implementation

[0075] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0076] Example 1, as Figure 5-9 As shown.

[0077] The external wall scaffolding lifting guide rail mechanism includes a guide rail 1, a locking support 2, and locking wall nails 4 horizontally fixed to the outer perimeter of the concrete floor slab 702. The guide rail 1 is fixed to the inner column 601 of the external wall scaffolding 6, and is divided into a lower locking fixing section 101 and an upper positioning guide section 102. The guide rail 1 has an internal space 104 that is open vertically, and a slot 105 on the front side facing the wall for the outer section of the locking wall nail 4 to extend into the internal space 104 and slide up and down. The locking support 2 is located in the internal space of the locking fixing section 101 of the guide rail and can be combined with the locking wall nail 4 to temporarily fix the external wall scaffolding 6 at a certain height. By placing the locking support 2 in the internal space of the locking fixing section 101 of the guide rail, it is possible to completely prevent concrete slurry from splashing onto the locking support 2 during the pouring of the upper floor slab 702, ensuring that all moving parts of the locking support 2 can work normally.

[0078] It should be noted that the external wall scaffolding 6 involved in this application is an integral part attached to the perimeter of the building under construction, just like in the prior art (see [reference]). Figure 1 , 2 The exterior wall scaffolding 6 is temporarily fixed to the three floor slabs 702 at the top of the already constructed three-story building. The fixing method involves setting three locking supports 2 on the locking section 101 of each guide rail 1 corresponding to the three floor slabs 702, and setting locking wall nails 4 on the outer periphery of each of the three floor slabs 702 (the specific method can be described in Embodiment 4). The three locking supports 2 of each guide rail 1 are respectively locked onto the corresponding locking wall nails 4 (see...). Figure 23 This ensures that the exterior wall scaffolding 6 does not sag or tilt outwards. The upper part of the exterior wall scaffolding 6 extends upwards to the height of the next floor to be built. Workers use the upper platform 603 of the exterior wall scaffolding 6 to walk and construct the next floor. After the construction of the floor slab 702 of the next floor is completed, locking wall nails 4 are installed on the outer perimeter of the floor slab 702 and constrained by the positioning guide section 102 (see Embodiments 3 and 4 for specific methods). Then, under the lifting force provided by several electric lifters (not shown in the figure) that uniformly execute lifting commands, the exterior wall scaffolding 6 is raised one floor. In the above manner, the exterior wall scaffolding 6 is raised one floor after each floor is built until the main building 7 is completed. After the entire main building 7 is completed, the exterior wall scaffolding 6 can be lowered layer by layer using the locking wall nails 4 installed during the rising process (see Embodiment 3 for specific methods). In this way, the encapsulation of the exterior wall and the decoration of the exterior wall surface can be completed layer by layer from top to bottom.

[0079] As the external wall scaffolding 6 rises to each floor, the three locking supports 2 of the locking and fixing section 101 simultaneously disengage from the locking wall nails 4 on the corresponding floor slab 702 and lock against the locking wall nails 4 on the floor slab 702 of the next floor. In this way, after the uppermost locking support 2 rises after disengaging from the locking wall nail 4 it is locked against, it naturally locks against the locking wall nail 4 set on the newly built floor slab 702 above.

[0080] The outer end of the wall nail 4 has a limiting handle 401, and its inner section (located at one end inside the wall of the floor slab 702) has external threads.

[0081] like Figure 26-30As shown, preferably, the retaining wall nail 4 also has a threaded sleeve 5 that mates with the external thread of its inner section and is embedded in the concrete of the floor slab 702. The outer periphery of the threaded sleeve 5 has raised grooves to prevent axial movement. That is, the retaining wall nail 4 does not directly contact the concrete of the floor slab 702, but rather the threaded sleeve 5 is embedded in the concrete when the floor slab 702 is poured. The threaded hole 501 mentioned above is the threaded hole 501 of the threaded sleeve 5. The opening of the threaded hole 501 of the threaded sleeve 5 embedded in the concrete of the floor slab 702 is located on the outer peripheral surface of the floor slab 702. In application, as described above, the retaining wall nail 4 can be directly screwed into the threaded hole 501 of the threaded sleeve 5.

[0082] like Figure 7-9 As shown, the inner space 104 of the guide rail 1 has a vertical partition 1040, which divides the inner space 104 into a front vertical locking space 1041 and a rear anti-tilting limiting space 1042. The partition 1040 has a second slot 106 parallel to the first slot 105, allowing the locking wall nail to pass through and slide up and down. The outer end of the locking wall nail 4 passes through the vertical locking space 1041 and enters the anti-tilting limiting space 1042. The limiting handle 401 at the outer end is located in the anti-tilting limiting space 1042, and the diameter of the limiting handle 401 is larger than the width of the second slot 106. The locking support 2 is located in the vertical locking space 1041. The limiting handle 401 at the outer end of the locking wall nail 4 is located in the anti-tilting limiting space 1042, preventing the guide rail 1 from tilting forward or backward, thus preventing the external wall scaffold 6 from tilting.

[0083] like Figure 9-11As shown, the locking support 2 includes a slotted base plate 201, a rotating shaft 203, and a support block 202. The slotted base plate 201 has a mounting groove 2011. The two ends of the rotating shaft 203 are respectively mounted on the groove walls on both sides of the mounting groove 2011. The support block 202 is mounted in the mounting groove 2011 via the rotating shaft 203 and can rotate around the rotating shaft 203. The lower part of the support block 202 below the rotating shaft 203 has a locking notch 2021 that opens to the outside. The upper part of the support block 202 above the rotating shaft 203 has a locking notch 2021. A tension spring 206 is provided between the inner side of the part and the bottom wall of the mounting groove 1 2011. The grooved seat plate 201 is fixed on one side of the locking space. When the outer side of the support block 202 is in a vertical state, it is close to the groove 1 105 and the groove 2 106. When the lower part of the support block 202 is not pressed, the tension spring 206 causes the lower part of the support block 202 to pop out of the mounting groove 1 2011, so that the locking wall nail 4 passing through the groove 1 105 and the groove 2 106 can be locked into the locking notch 2021, so that the external wall scaffolding 6 cannot fall. During application, the locking support 2 rises with the external wall scaffolding 6. The locking wall nail 4, passing through slot one 105 and slot two 106, slides down the outer side of the support block 202. During the sliding process, it presses the support block 202 into the installation slot one 2011. When it slides to the locking notch 2021 at the bottom of the support block 202, the bottom of the support block 202 pops out, allowing the locking wall nail 4 to enter the locking notch 2021 (see...). Figure 14 (and corresponding accompanying illustrations).

[0084] The lower side of the notch 2021 of the support block 202 to the lower end of the support block 202 forms an arc-shaped bidirectional guide surface 2022. When the locking support 2 rises with the external wall scaffolding 6 (see...), Figure 12-15 (and corresponding attached diagrams). The locking wall nail 4, which is engaged in the locking notch 2021, can slide down from the upper part of the bidirectional guide surface 2022 from the locking notch 2021, and press the lower part of the support block 202 into the mounting groove 2011 during the downward sliding process. When the locking support 2 descends with the external wall scaffolding 6, the locking wall nail 4 can slide up from the lower part of the bidirectional guide surface 2022, and press the lower part of the support block 202 into the mounting groove 2011 during the upward sliding process. In this way, the locking wall nail 4 can slide down and up on the bidirectional guide surface 2022, and in both cases, it can press the lower part of the support block 202 into the mounting groove 2011.

[0085] The locking support 2 also includes a reverse closing tongue plate 204. A vertical mounting groove 2023 is provided in the middle of the bidirectional guide surface 2022. One end of the reverse closing tongue plate 204 is installed in the mounting groove 2023 through a rotating shaft 205 and can rotate up and down around the rotating shaft 205. The tip of the tongue plate 204 can rotate upward to overlap the outer side of the support block 202 above the locking notch 2021, thus closing the locking notch 2021. A torsion spring 207 is provided between the rotating shaft 205 and the reverse closing tongue plate 204. When no external force is applied, the torsion spring 207 keeps the reverse closing tongue plate 204 in an oblique outward and downward posture and forms an angle with the lower part of the bidirectional guide surface 2022. When an external force is applied, the reverse closing tongue plate 204 can rotate upward or downward.

[0086] When the support block 202 rises with the external wall scaffolding 6 (see...) Figure 12-15 (and corresponding attached diagrams), the locking wall nail 4, which slides out of the locking notch 2021, can continue to slide down along the reverse closing tongue plate 204, pressing the reverse closing tongue plate 204 into the mounting groove 2023. When the support block 202 descends with the external wall scaffolding 6 (see...), Figure 17-18 (and corresponding attached diagrams), the locking wall nail 4 located below the support block 202 can slide upward along the lower part of the bidirectional guide surface 2022 and contact the reverse closing tongue plate 204, pushing the reverse closing tongue plate 204 to rotate upward and block the locking notch 2021, so that the support block 202 can slide smoothly downward through the locking wall nail 4, ensuring that the downward movement of the external wall scaffold 6 is not obstructed by the locking support 2.

[0087] Example 2, as Figure 6 , 19 As shown in -22.

[0088] The external wall scaffolding lifting guide rail mechanism also includes a wall nail locator (3); the guide rail 1 has a mounting base plate 107, and the top of the positioning guide section 102 of the guide rail 1 has a compensating guide rail 103 with the same structure as the guide rail 1 that can slide up and down on the mounting base plate 107. The wall nail locator 3 is hinged on the mounting base plate 107 behind the junction of the compensating guide rail 103 and the positioning guide section 102 via a hinge shaft 303. When the compensating guide rail 103 slides upward, the wall nail locator 3 can rotate around the hinge shaft 303 into the gap 100 between the compensating guide rail 103 and the positioning guide section 102. The wall nail locator 3 has a large-diameter hole 301 on the rear side that is forward-facing to accommodate the limiting handle 401 of the wall nail 4, and a small-diameter hole 302 on the front side that passes through the large-diameter hole 301 and the front side of the wall nail locator 3. The diameter of the small-diameter hole 302 is only large enough to allow the inner and outer sections of the wall nail 4 to pass through.

[0089] The wall nail locator 3 precisely sets threaded holes 501 for the wall nails 4 on the newly built floor slab 702. The specific usage method is detailed in Embodiment 4 below, which describes the method of positioning the wall nails using the wall nail locator. Thus, by setting the wall nail locator 3 on the upper part of the guide rail 1, the wall nail locator is positioned during the pouring of the previous floor slab 702, leaving threaded holes 501 for the inner section of the wall nail 4 to be screwed in. This achieves precise positioning of the threaded holes 501, allowing the wall nails 4 to be screwed in directly during application. This ensures that the wall nails 4 are installed accurately on the outer perimeter of the floor slab 702, and the installation speed is also very fast. Since raising the external wall scaffolding 6 to one floor requires the installation of dozens or even hundreds of wall nails 4, a significant amount of installation time is saved, thereby significantly improving work efficiency.

[0090] The working principle of the compensating guide rail 103 is that after the positioning wall nail 4 is screwed into the threaded hole 501 set on the newly built floor slab 702 and the fixing installation of the positioning wall nail 4 is completed, the compensating guide rail 103 is moved down to connect with the positioning guide section 102. When moving down, the outer section of the positioning wall nail 4 enters the groove 105 and groove 106 of the compensating guide rail 103 from the lower port of the compensating guide rail 103, and the limiting handle 401 at the outer end of the positioning wall nail 4 is located in the anti-tilting limiting space 1042 of the compensating guide rail 103, so as to ensure that the positioning wall nail 4 can smoothly slide from the compensating guide rail 103 into the positioning guide section 102 of the guide rail 1 when the external wall scaffolding 6 rises. When the compensating guide rail 103 moves down and aligns with the positioning guide section 102, the outer segment of the locking wall nail 4 enters the slot 105 and slot 2 106 of the compensating guide rail 103 from the lower port of the compensating guide rail 103, and the limiting handle 401 at the outer end of the locking wall nail 4 is located in the anti-tilt limiting space 1042 of the compensating guide rail 103, it is considered that the outer segment of the locking wall nail 4 is already located in the inner space 104 of the positioning guide section 102, and its limiting handle 401 is located in the anti-tilt limiting space 1042 of the inner space 104 of the positioning guide section 102.

[0091] The compensating guide rail 103 can slide up and down on the mounting base plate 107. It has L-shaped angle iron pieces 108 symmetrically arranged on both sides of the mounting base plate 107. A groove 1081 is formed between the angle iron pieces 108 and the mounting base plate 107. Folded feet 1031 are provided on both sides of the compensating guide rail 103, which are located in the groove 1081 and can slide up and down in the groove 1081.

[0092] Example 3: A method for raising and lowering external wall scaffolding using the external wall scaffolding lifting guide rail mechanism described in Example 1, illustrated by raising and lowering the external wall scaffolding 6 by one floor. Raising the external wall scaffolding 6 by one floor includes the following steps:

[0093] A1. Fix the positioning wall nail 4 on the newly built floor slab 702 of the upper floor, and position the outer section of the positioning wall nail 4 within the inner space 104 of the guide rail positioning guide section 102, so that the limiting handle 401 is located within the anti-tilting limiting space 1042 of the inner space 104. See [reference needed]. Figure 30 ;

[0094] A2. Under the lifting force provided by the lifting mechanism, the external wall scaffolding 6 rises, causing the wall nails 4 on each floor, which are in a supported state, to slide downwards from the notches 2021 of the support blocks 202 of the supported supports 2, which are in a supported state. See [reference needed]. Figure 14 , 15 ;

[0095] A3. The exterior wall scaffolding 6 continues to rise. When the wall nail 4 on the upper floor slides down along the outer side of the support block 202 of the support bracket 2 rising from the lower floor and enters the positioning gap 2021, the exterior wall scaffolding 6 stops rising. See [link / reference]. Figure 12-14 ;

[0096] A4. The lifting mechanism releases the force on the external wall scaffolding 6. Under the action of gravity, the support block 202 of the external wall scaffolding 6 presses its upper side through the locking notch 2021 onto the locking wall nail 4 that enters the locking notch 2021. See Figure 14 .

[0097] In this way, the operation of raising the external wall scaffold 6 to one floor around the outer perimeter of the building structure 7 under construction is completed, and then the raised external wall scaffold 6 is used to continue the pouring construction of the next floor.

[0098] The steps for lowering the external wall scaffolding to one floor (6 stories) are as follows:

[0099] B1. Raise the exterior wall scaffolding 6, allowing the wall nails 4, which are in a supported state on each floor, to slide down from the notches 2021 of the support blocks 202 of their respective support brackets 2 to below the support blocks 202. The raising of the exterior wall scaffolding 6 will then stop. See below. Figure 14-16 ;

[0100] B2. Lower the external wall scaffolding 6. The locking wall nail 4 slides upward along the lower part of the bidirectional guide surface 2022 of the support block 202 that has just been dislodged. After contacting the reverse closing tongue plate 204, the reverse closing tongue plate 204 is forced to rotate upward to block the locking notch 2021, causing the locking wall nail 4 to slide upward past the support block 202. See [link / reference] Figure 17 , 18 ;

[0101] B3. Continue lowering the exterior wall scaffolding 6 until each locking support 2 is close to the locking wall nails 4 of the next floor. Following method B2, stop lowering when the locking wall nails 4 of the next floor slide upwards past the support block 202 to close the reverse closing tongue plate 204 of the locking notch 2021. At this point, the reverse closing tongue plate 204 automatically rotates downwards under the action of the torsion spring, releasing the closure of the locking notch 2021. See [link / reference]. Figure 13 The state of the reverse closed tongue plate 204 in the middle;

[0102] B4. Raise the exterior wall scaffolding 6. Following method A3, lower the wall anchoring nails 4 of the next floor until they enter the anchoring gap 2021. Then stop raising the exterior wall scaffolding 6. (See below) Figure 13 , 14 ;

[0103] B5. Following method A4, press the support block 202 against the locking wall nail 4 in the locking notch 2021 through its upper side within the locking notch 2021. (See above) Figure 14 .

[0104] In this way, the operation of lowering the external wall scaffolding 6 by one floor around the building under construction is completed, and the lowered external wall scaffolding 6 is used to enclose the exterior wall of the completed building structure 7 layer by layer downwards.

[0105] It should be noted that the sliding or rising of the wall-mounted locking nail mentioned many times in this article refers to the lifting or lowering of the locking support; in reality, the wall-mounted locking nail is fixed in place.

[0106] Example 4, as Figure 21-29 As shown.

[0107] A method for positioning wall nails using the wall nail locator 3 described in Embodiment 1 includes the following steps:

[0108] C1. Before pouring the next floor slab 702, slide the compensating guide rail 103 upwards, see [reference]. Figure 21 ;

[0109] C2. Rotate the wall nail locator 3 around the hinge axis 303 into the gap 100 between the compensating guide rail 103 and the positioning guide section 102. See Figure 21-24 ;

[0110] C3. Using drill bit 9, drill template hole 801 in template 8 through the large diameter hole 301 and small diameter hole 302 of wall nail locator 3. (See below) Figure 25 ;

[0111] C4. Rotate the wall nail locator 3 in the opposite direction around the hinge shaft 303 until an operating gap is left between the compensation guide rail 103 and the positioning guide section 102.

[0112] C5. Enlarge the template hole 801, because the template hole 801 drilled by the drill bit 9 cannot be directly inserted into the threaded sleeve 5.

[0113] C6. Pass the inner section with external threads of the positioning wall nail 4 through the large-diameter hole 301, the small-diameter hole 302 of the wall nail locator 3, and the template hole 801 on the template 8 in sequence. The small-diameter hole 302 defines the posture of the positioning wall nail 4. Screw the threaded sleeve 5 with anti-slip texture on its outer periphery onto the inner section of the positioning wall nail 4. See [link / reference] Figure 26 ;

[0114] C7. When pouring the upper floor slab 702, the threaded sleeve 5 is cast into the concrete, see [reference]. Figure 27 ;

[0115] C8. After the concrete has hardened, unscrew the locking wall nails 4 from the threaded sleeves 5, and remove the formwork 8. (See below) Figure 28 ;

[0116] C9. Re-screw the retaining wall nail 4 into the threaded hole of the threaded sleeve 5. See below. Figure 29 .

[0117] The above embodiments are only used to describe the present invention more clearly, and should not be regarded as limiting the scope of protection covered by the present invention. Any equivalent modifications should be regarded as falling within the scope of protection covered by the present invention.
