Description

Technical Field

[0001] This invention relates to the field of building engineering technology, specifically to a device for repairing and fixing the shape lines of exterior wall panels. Background Technology

[0002] Exterior wall panels are commonly used exterior wall cladding components in prefabricated buildings. They offer stable overall performance and possess comprehensive properties such as lightweight, thermal insulation, fire resistance, and sound insulation. Exterior wall concrete moldings are cast-in-place concrete decorative and functional structural components located at floor levels, around window openings, or at eaves on the building facade. They serve multiple functions, including facade decoration, drainage, and facade finishing protection, and are ancillary cast-in-place concrete structures for the exterior walls.

[0003] When repairing the decorative lines of existing prefabricated building exterior wall panels, it is often necessary to cut the exterior wall panels. This can easily lead to rainwater seeping along the gaps between the decorative lines and the exterior wall panels, causing problems such as mold growth on the inside of the wall panels and peeling of the wall paint. Summary of the Invention

[0004] The purpose of this invention is to provide a device for repairing and fixing the decorative lines of exterior wall panels, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

A bend protrusion is provided between the insert rod and the hook. The binding elbow is welded to the upper side of the bend protrusion. The end of the insert rod is provided with an external thread and an internal thread for extraction. An extraction assembly is provided with the internal thread for extraction. The extraction assembly passes through the exterior wall panel and removes the hook bolt from the storage assembly to connect with the exterior wall panel. A horizontal reinforcing bar is tied to the binding elbow of the hook bolt. The hook bolt, together with the horizontal reinforcing bar, forms a decorative line after concrete is poured in the template.

[0007] As a further embodiment of the present invention: the storage component includes a storage rack, the storage rack having two parallel mating grooves, the bottom of the hook and the bottom of the binding elbow respectively mating with the parallel mating grooves, the edges of the two mating grooves having fixing grooves, the sides of the hook and the binding elbow mating with the fixing grooves, the bottom of the storage rack being connected to a moving component, the storage rack being placed on the surface of the template and moving horizontally along the edge of the outer wall panel in conjunction with the moving component.

[0008] As a further embodiment of the present invention: the movable component includes a side frame disposed on the edge of the outer wall panel, the two ends of the side frame being disposed on the inner and outer sides of the outer wall panel respectively, guide pulleys being rotatably mounted on the two ends of the side frame, a connecting rope being installed between the guide pulleys, the connecting rope forming a rectangular structure through the guide pulleys, a connecting protrusion being provided at the bottom of the storage rack, and the connecting rope being connected to the connecting protrusion.

[0009] As a further embodiment of the present invention: the bottom of the storage rack is provided with a connecting groove, two sets of movable plates are slidably installed in the connecting groove, a guide rope is provided between the side frames, the guide rope passes through the movable plates, the storage rack is placed on the surface of the template through the movable plates, and a support spring is provided on the guide rope between the movable plates.

[0010] As a further embodiment of the present invention: the extraction assembly includes an extraction rod, which passes through a countersunk hole in the outer wall panel from the inside out and engages with the extraction internal thread of the insertion rod. A tightening sleeve is sleeved on one end of the extraction rod located inside the outer wall panel, and a fixing nut is fitted inside the tightening sleeve. A rotating wrench perpendicular to each other is assembled and installed on the end of the extraction rod.

[0011] As a further embodiment of the present invention: the drilling mechanism includes a movable frame, on which multiple sets of abutment rods are provided, and at the end of each abutment rod is an abutment wheel. The abutment wheel contacts the inner side of the outer wall panel. A support plate is provided on the top of the movable frame, and a tilt adjustment component is provided on the support plate. The tilt adjustment component is connected to a drilling machine.

[0012] As a further embodiment of the present invention: the tilt adjustment assembly includes an adjustment frame disposed on the upper side of a support plate, a support column rotatably mounted at the end of the adjustment frame, an aiming spotlight rotatably mounted at the rotatable connection of the support column rotatably mounted, the bottom of the support column rotatably mounted and the support plate being fixedly connected, an adjustment groove disposed in the middle of the adjustment frame, a support column slidably mounted in the adjustment groove, an aiming spotlight rotatably mounted at the top of the support column rotatably mounted, the bottom of the support column rotatably mounted and the support plate being inserted into the support plate, an adjustment bolt disposed on the side of the support plate, the adjustment bolt abutting against the side of the support column rotatably mounted, an approach frame slidably mounted on the adjustment frame, and a drilling machine fixedly mounted on the approach frame.

[0013] As a further embodiment of the present invention: the template includes a fixed plate and a flip plate. The fixed plate is fixedly installed below the countersunk hole of the outer wall panel. The flip plate is rotatably installed on the edge of the fixed plate. The edge of the fixed plate is provided with a bracket. When the bottom of the flip plate contacts the bracket, the fixed plate and the flip plate are on the same horizontal plane.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) The hook bolts are placed in the storage assembly in batches. The storage assembly moves along the outer edge of the outer wall panel. When the hook bolt reaches the countersunk hole, the hook bolt in the storage assembly is extracted by the extraction assembly. The insertion rod of the hook bolt is inserted into the countersunk hole from the outside to the inside. The hook part contacts the surface of the outer wall panel to form a limit. After the insertion rod is inserted into the countersunk hole, it is fixed and installed by the washer and the fixing nut. The tie-up elbow part is tied with the horizontal steel bar by the tie wire to form the steel bar skeleton. After the template is combined with the cast-in-place, the shape line structure is obtained.

[0016] (2) Two parallel mating grooves cooperate with the hook and the bottom of the binding elbow. At the same time, a fixing groove is set on the side of the mating groove to limit the hook bolt. When the hook bolt moves with the storage rack, it prevents the hook bolt from tipping over. At the same time, it is convenient for the extraction component to extract the hook bolt. After extraction, the hook bolt is removed from the fixing groove. The continued movement of the storage rack will cause the hook bolt to separate from the storage rack, thus making it convenient for the extraction component to install the hook bolt into the countersunk hole.

[0017] (3) Connect the storage components with connecting ropes. When installing the hook bolts, manually pull the connecting ropes on the inside of the outer wall panel to move the storage components along the edge of the outer wall panel. Use the extraction components to extract the hook bolts in sequence. After extraction, fix the hook bolts to the countersunk holes. After the preliminary preparation work is completed, the operator can carry out the construction work on the inside of the outer wall panel to complete the fixed installation between the hook bolts and the countersunk holes. This avoids the operator working at height and near the edge for a long time, and is not affected by the external environment. The efficiency of hook bolt installation is greatly improved.

[0018] (4) Use two parallel marking lines to mark the tilt angle of the drilling machine so that the countersink is drilled outward at an tilt angle, further avoiding potential problems such as external water seepage. Before drilling, first bring the moving frame close to the inside of the outer wall panel, and then use the abutment rod and abutment wheel to abut against the inner surface of the outer wall panel. Adjust the height of the moving frame so that the drilling machine reaches the drilling height. At this time, align the first and second aligning lights with the two parallel marking lines on the outer wall panel in sequence, so that the drilling machine points at an tilt angle towards the outer wall panel. Manually control the approach frame and the drilling machine to perform countersinking on the wall panel. Attached Figure Description

Detailed Implementation

[0031] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0032] like Figures 1-4 , Figure 9 As shown, a device for repairing and fixing the molding lines of an exterior wall panel includes a template 1, hook bolts 3, and a storage assembly 2 mounted on the exterior wall panel. The hook bolts 3 are evenly placed in the storage assembly 2. A drilling mechanism 5 is provided on the inner side of the exterior wall panel, which drills multiple countersunk holes 300 from the inside to the outside of the exterior wall panel. The hook bolts 3 are inserted into the exterior wall panel from the outside to the inside along the countersunk holes 300 and then fixedly installed between the hook bolts and the exterior wall panel. The storage assembly 2 moves horizontally on the outer side of the exterior wall panel and releases the hook bolts 3 sequentially. The hook bolt 3 includes an insert rod 30 and a hook 3. 2. A binding elbow 33 is provided between the insert rod 30 and the hook 32. The binding elbow 33 is welded to the upper side of the elbow protrusion 320. The end of the insert rod 30 is provided with a connecting external thread 31 and an extraction internal thread 34. The extraction internal thread 34 is equipped with an extraction component. After the extraction component passes through the outer wall panel, it is taken out from the storage component 2 and connected to the outer wall panel. A horizontal steel bar is bound to the binding elbow 33 of the hook bolt 3. The hook bolt 3 and the horizontal steel bar are used to form a shape line after concrete is poured in the template 1.

[0033] Specifically, the hook bolts 3 are placed in batches in the storage component 2. The storage component 2 moves along the outer edge of the outer wall panel. When the hook bolts 3 reach the countersunk hole 300, the hook bolts 3 in the storage component 2 are extracted using the extraction component. This allows the insertion rod 30 of the hook bolt 3 to be inserted into the countersunk hole 300 from the outside in. The hook 32 contacts the surface of the outer wall panel to form a limit. After the insertion rod 30 is inserted into the countersunk hole 300, it is fixed and installed by the washer 35 and the fixing nut 36. The binding elbow 33 is tied with horizontal steel bars by binding wire to form a steel skeleton. After the template 1 is combined with the concrete cast-in-place, the shape line structure is obtained.

[0034] It should be noted that a bend protrusion 320 is provided at the connection between the hook 32 and the insertion rod 30. The outwardly extending bend protrusion 320 facilitates the welding positioning of the binding bend 33, ensuring the welding reliability of the binding bend 33, and thus ensuring the overall reliability after subsequent concrete pouring.

[0035] During construction, it is important to note that before drilling, a laser level should be used to mark the inside of the exterior wall panel to ensure that the height of the countersunk holes 300 is consistent. After drilling the countersunk holes 300, the dust inside the countersunk holes 300 needs to be cleaned. After the insertion rod 30 is installed, anti-rust paint should be injected into the countersunk holes 300 to protect the insertion rod 30 and prevent subsequent corrosion.

[0036] When the molding lines formed by traditional techniques are damaged and need to be repaired or recast, the old molding lines are first removed, holes are drilled using the aforementioned equipment, the steel reinforcement skeleton is tied, and then concrete is poured to complete the repair work of the molding lines.

[0037] Furthermore, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 As shown, the storage component 2 includes a storage rack 20. The storage rack 20 has two parallel mating grooves 21. The bottom of the hook 32 and the bottom of the binding elbow 33 respectively mate with the parallel mating grooves 21. The edges of the two mating grooves 21 are provided with fixing grooves 22. The sides of the hook 32 and the binding elbow 33 mate with the fixing grooves 22. The bottom of the storage rack 20 is connected to a moving component 4. The storage rack 20 is placed on the surface of the template 1 and moves horizontally along the edge of the outer wall panel in conjunction with the moving component 4.

[0038] Specifically, the hook bolts 3 are evenly placed inside the storage rack 20. They are engaged with the hook 32 and the bottom of the binding elbow 33 through two parallel mating grooves 21. At the same time, a fixing groove 22 is provided on the side of the mating groove 21 to limit the hook bolts 3. When the hook bolts 3 move with the storage rack 20, it prevents the hook bolts 3 from tipping over. It also facilitates the extraction component to extract the hook bolts 3. After extraction, the hook bolts 3 are separated from the fixing groove 22. The continued movement of the storage rack 20 will cause the hook bolts 3 to separate from the storage rack 20, so that the extraction component can install the hook bolts 3 into the countersunk hole 300.

[0039] Furthermore, such as Figure 1 , Figure 6 , Figure 7 As shown, the movable component 4 includes a side frame 42 disposed on the edge of the outer wall panel. The two ends of the side frame 42 are respectively disposed on the inner and outer sides of the outer wall panel. Guide pulleys 43 are rotatably mounted on both ends of the side frame 42. A connecting rope 40 is installed between the guide pulleys 43. The connecting rope 40 forms a rectangular structure through the guide pulleys 43. A connecting protrusion 24 is provided at the bottom of the storage rack 20. The connecting rope 40 is connected to the connecting protrusion 24.

[0040] Specifically, the storage component 2 is connected via connecting rope 40. When installing the hook bolt 3, the connecting rope 40 is manually pulled from the inside of the outer wall panel, causing the storage component 2 to move along the edge of the outer wall panel. This, combined with the extraction component, allows the hook bolt 3 to be extracted sequentially. After extraction, the hook bolt 3 is fixedly installed between itself and the countersunk hole 300. After the preliminary preparations are completed, operators can work from the inside of the outer wall panel to complete the installation of the hook bolt 3 between itself and the countersunk hole 300. This avoids long-term high-altitude, edge-prone work for operators and minimizes external environmental interference, significantly improving the installation efficiency of the hook bolt 3.

[0041] Furthermore, such as Figure 1 , Figure 5 , Figure 6 , Figure 7 As shown, the bottom of the storage rack 20 is provided with a connecting groove 23, and two sets of movable plates 25 are slidably installed in the connecting groove 23. A guide rope 41 is provided between the side frames 42. The guide rope 41 passes through the movable plates 25. The storage rack 20 is placed on the surface of the template 1 through the movable plates 25. A support spring 26 is provided on the guide rope 41 between the movable plates 25.

[0042] Specifically, in order to ensure that the storage rack 20 moves parallel to the outer wall panel, a guide rope 41 is set between the side frames 42. When the connecting rope 40 is pulled, the storage rack 20 carries the hook bolt 3 and moves along the guide rope 41 to prevent the storage rack 20 from deviating and to ensure that the subsequent extraction components can smoothly extract the hook bolt 3.

[0043] Furthermore, such as Figures 3-5 , Figure 9 As shown, the extraction assembly includes an extraction rod 60, which passes through a countersunk hole 300 in the outer wall panel from the inside out and engages with the extraction internal thread 34 of the insertion rod 30. A tightening sleeve 61 is sleeved on one end of the extraction rod 60 located inside the outer wall panel, and a fixing nut 36 is provided inside the tightening sleeve 61. A rotating wrench 62 perpendicular to each other is assembled on the end of the extraction rod 60.

[0044] Specifically, when the storage rack 20 carrying the hook bolt 3 is aligned with the countersunk hole 300, the extraction rod 60 is first inserted into the countersunk hole 300. By installing a rotary wrench 62 on the inner end of the extraction rod 60, the end of the extraction rod 60 is screwed into the extraction internal thread 34 of the insertion rod 30. Then, the moving component 4 drives the storage rack 20 to move. At this time, the hook bolt 3 is disengaged from the storage rack 20. The extraction rod 60 is used to insert the hook bolt 3 into the countersunk hole 300. The rotary wrench 62 is removed, and the washer 35, the fixing nut 36, and the tightening sleeve 61 are sequentially fitted onto the extraction rod 60. Then, the tightening sleeve 61 is rotated with the tool so that the fixing nut 36 and the connecting external thread 31 at the end of the insertion rod 30 cooperate with each other, thereby completing the fixed installation between the hook bolt 3 and the countersunk hole 300.

[0045] Furthermore, such as Figure 1 , Figure 10 , Figure 11 As shown, the drilling mechanism 5 includes a movable frame 50, on which multiple sets of abutment rods 51 are provided. The end of each abutment rod 51 is provided with an abutment wheel 52, which contacts the inner side of the outer wall panel. A support plate 53 is provided on the top of the movable frame 50, and a tilt adjustment component is provided on the support plate 53. The tilt adjustment component is connected to a drilling machine 54. The tilt adjustment assembly includes an adjustment frame 55 disposed on the upper side of the support plate 53. A support column 58 is rotatably mounted at the end of the adjustment frame 55. A directional spotlight 59 is disposed at the rotatable connection part of the support column 58. The bottom of the support column 58 is fixedly connected to the support plate 53. An adjustment groove 57 is disposed in the middle part of the adjustment frame 55. A support column 510 is slidably mounted in the adjustment groove 57. A directional spotlight 511 is disposed at the top of the support column 510. The bottom of the support column 510 is inserted into the support plate 53. An adjustment bolt 512 is disposed on the side of the support plate 53. The adjustment bolt 512 abuts against the side of the support column 510. An approach frame 56 is slidably mounted on the adjustment frame 55. The drilling machine 54 is fixedly mounted on the approach frame 56.

[0046] Specifically, before drilling, a laser level is used to mark the drilling area, and two parallel lines 301 are marked on the drilling area using the laser level. The two parallel lines 301 are used to calibrate the tilt angle of the drilling machine 54, so that the countersunk hole 300 is drilled outward at an tilt angle, further avoiding potential problems such as external water seepage later. Before drilling, the moving frame 50 is first brought close to the inner side of the outer wall panel, and the abutment rod 51 and abutment wheel 52 are used to abut against the inner surface of the outer wall panel. The height of the moving frame 50 is adjusted so that the drilling machine 54 reaches the drilling height. At this time, the first and second alignment spotlights 59 and 511 are aligned with the two parallel lines 301 on the outer wall panel in sequence, so that the drilling machine 54 is tilted towards the outer wall panel. Then, the approach frame 56 and the drilling machine 54 are manually controlled to process the countersunk hole 300 in the wall panel.

[0047] Furthermore, such as Figure 1 , Figure 8 , Figure 9 As shown, the template 1 includes a fixed plate 10 and a flip plate 11. The fixed plate 10 is fixedly installed below the countersunk hole 300 of the outer wall panel. The flip plate 11 is rotatably installed on the edge of the fixed plate 10. The edge of the fixed plate 10 is provided with a bracket 12. When the bottom of the flip plate 11 contacts the bracket 12, the fixed plate 10 and the flip plate 11 are on the same horizontal plane.

[0048] Specifically, during the processing of the hook bolt 3, the flip plate 11 is kept horizontal to facilitate the movement of the storage component 2 along the template 1, thereby installing the hook bolt 3. After the installation is completed, the storage component 2 and the moving component 4 are removed. Workers enter the scaffold to tie the horizontal steel bars to the hook bolt 3. Finally, the flip plate 11 is flipped up to form a pouring space. Then, concrete is poured in the template 1 to complete the repair work of the shape lines.

[0049] The working principle of this invention embodiment is as follows:

[0050] like Figures 1-11As shown, hook bolts 3 are placed in batches in storage assembly 2. As storage assembly 2 moves along the outer edge of the exterior wall panel, when the hook bolts 3 reach the countersunk hole 300, the extraction assembly is used to extract the hook bolts 3 from storage assembly 2. This allows the insertion rod 30 of the hook bolt 3 to be inserted into the countersunk hole 300 from the outside in. The hook 32 contacts the surface of the exterior wall panel to form a limit. After the insertion rod 30 is inserted into the countersunk hole 300, it is fixed in place by washer 35 and fixing nut 36. The binding elbow 33 is tied with horizontal reinforcing bars using binding wire to form a reinforcing steel skeleton. Subsequently, after being cast in place with template 1, the shaped linear structure is obtained. Before drilling, a laser level needs to be used to mark the inside of the exterior wall panel to ensure that the height of the countersunk holes 300 is consistent. After drilling the countersunk hole 300, the dust inside the countersunk hole 300 needs to be cleaned. After the insertion rod 30 is installed, anti-rust paint is injected into the countersunk hole 300 to protect the insertion rod 30 and prevent it from rusting later. The hook bolts 3 are evenly placed in the storage rack 20. They cooperate with the bottom of the hook 32 and the binding elbow 33 through two parallel mating grooves 21. At the same time, the fixing grooves 22 are set on the side of the mating grooves 21 to limit the hook bolts 3. When the hook bolts 3 move with the storage rack 20, they are prevented from tipping over. At the same time, it is easy for the extraction component to extract the hook bolts 3. After extraction, the hook bolts 3 are separated from the fixing grooves 22. The continued movement of the storage rack 20 will cause the hook bolts 3 to detach from the storage rack 20, so that the extraction component can install the hook bolts 3 into the countersunk hole 300. The storage component 2 is connected via connecting rope 40. When installing the hook bolt 3, the connecting rope 40 is manually pulled from the inside of the outer wall panel, causing the storage component 2 to move along the edge of the outer wall panel. This, combined with the extraction component, allows the hook bolt 3 to be extracted sequentially. After extraction, the hook bolt 3 is fixedly installed between itself and the countersunk hole 300. After the preliminary work is completed, the operator can work from the inside of the outer wall panel to complete the fixed installation between the hook bolt 3 and the countersunk hole 300, avoiding long-term high-altitude edge work for the operator and minimizing external environmental interference, thus greatly improving the installation efficiency of the hook bolt 3. To ensure that the storage rack 20 moves parallel to the outer wall panel, guide ropes 41 are installed between the side frames 42. When the connecting rope 40 is pulled, the storage rack 20 carries the hook bolt 3 along the guide rope 41, preventing the storage rack 20 from shifting and ensuring that the subsequent extraction component can smoothly extract the hook bolt 3.When the storage rack 20 carrying the hook bolt 3 is aligned with the countersunk hole 300, the extraction rod 60 is first inserted into the countersunk hole 300. By installing a rotary wrench 62 on the inner end of the extraction rod 60, the end of the extraction rod 60 is screwed into the extraction internal thread 34 of the insertion rod 30. Then, the moving component 4 drives the storage rack 20 to move. At this time, the hook bolt 3 is disengaged from the storage rack 20. The extraction rod 60 is used to insert the hook bolt 3 into the countersunk hole 300. The rotary wrench 62 is removed. The washer 35, the fixing nut 36, and the tightening sleeve 61 are then fitted onto the extraction rod 60 in sequence. Then, the tightening sleeve 61 is rotated with the tool so that the fixing nut 36 and the connecting external thread 31 at the end of the insertion rod 30 cooperate with each other, thereby completing the fixed installation between the hook bolt 3 and the countersunk hole 300. Before drilling, the drilling area is marked using a laser level, and two parallel lines 301 are marked on the drilling area using the laser level. The two parallel lines 301 are used to calibrate the tilt angle of the drilling machine 54, so that the countersunk hole 300 is drilled outward at an tilt angle, further avoiding potential problems such as external water seepage later. Before drilling, the moving frame 50 is first moved close to the inner side of the outer wall panel, and the abutment rod 51 and abutment wheel 52 are used to abut against the inner surface of the outer wall panel. The height of the moving frame 50 is adjusted so that the drilling machine 54 reaches the drilling height. At this time, the first and second alignment spotlights 59 and 511 are aligned with the two parallel lines 301 on the outer wall panel in sequence, so that the drilling machine 54 is tilted towards the outer wall panel. The approach frame 56 and the drilling machine 54 are manually controlled to process the countersunk hole 300 in the wall panel.
