Description

Technical Field

[0001] This invention relates to the field of building construction, specifically to a scaffolding system for building ceiling decoration and renovation and its construction method. Background Technology

[0002] Construction scaffolding for ceiling decoration and renovation typically refers to specialized tools, equipment, or systems used to assist or complete the installation, decoration, and renovation of interior ceilings. Currently, scaffolding is required during interior decoration work to facilitate ceiling construction. However, existing scaffolding is typically erected temporarily before construction begins and cannot be secured during setup. Using rivets for fixation would inevitably damage the interior walls. Conversely, rivets need to be embedded in the walls to secure the ceiling decoration framework during installation. Therefore, a scaffolding system that integrates with the ceiling framework can be installed, utilizing existing rivets embedded in the walls, to achieve good stability and ensure the safety of construction workers.

[0003] Secondly, when installing gypsum board for ceiling decoration, if special caulking plaster and joint tape are not used in the gaps between the boards, or if the screws are not evenly fixed from the center outwards during installation, uneven stress will be generated on the boards, eventually releasing and forming cracks on the wall paint surface between the boards. These cracks need to be repaired continuously. Therefore, a construction device that can stably support and install ceiling gypsum board is needed to prevent problems such as tilting and uneven stress during installation, and to avoid cracks between two gypsum boards. Summary of the Invention

[0004] This invention provides a scaffolding and construction method for building ceiling decoration and renovation, which overcomes the shortcomings described in the background art.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A construction scaffold for ceiling decoration and renovation includes a frame body and multiple threaded telescopic rods supported at the lower end of the frame body. Two adjacent threaded telescopic rods are connected by retaining members, and a supporting member is fixed on the retaining member. The supporting member and the threaded telescopic rod form an H-shaped connection.

[0007] The retaining member includes a connector, a fastening member, and a fixing plate. The connector is sleeved on the threaded telescopic rod by the fastening members provided at both ends of the connector, and the fixing plate is fixed to the outside of the fastening member.

[0008] The threaded telescopic rod includes a threaded rod and sleeves fitted on the upper and lower sides of the outer end of the threaded rod. Both sleeves are threadedly connected to the threaded rod, so that the distance between the two sleeves can be adjusted by rotating the threaded rod. The connecting piece is fitted on the outside of the threaded rod.

[0009] The fastener has an opening on its side, through which it is fitted onto the threaded rod. The side of the fastener closest to the opening protrudes outward, and the fixing plate is fitted onto the protrusion.

[0010] In a preferred embodiment, the support member includes a support plate and a support rod for supporting the support plate. The support plate has a first recessed groove in the middle, and the support plate is connected to the retaining member through the first groove. The side of the support plate near the support rod extends outward, and the side of the support plate away from the support rod is inclined and abuts against the wall surface.

[0011] In a preferred embodiment, each bend on the outer edge of the frame body is provided with an installation groove, and a seam repair strip is provided in the installation groove. The seam repair strip is attracted to the frame body by a magnetic plate provided at its bottom. The lower end of the seam repair strip is provided with an inwardly extending injection cavity, and the injection cavity is connected to the outside through a guide port provided on its side. The guide port extends along the length direction of the seam repair strip.

[0012] The edge repair strip is set at one end near the flow port with an inclined surface. Both ends of the gypsum board extend to the inclined edge of the edge repair strip on both sides. The gypsum board is provided with multiple equidistant guide grooves near the inclined surface of the edge repair strip. The flow port is provided with an inwardly recessed step edge on the side near the guide groove. When two edge repair strips are brought together at an angle, the step edges on the two edge repair strips form a flow channel, which is connected to the guide groove.

[0013] A preferred technical solution is that the upper and lower sides of the inner end of the frame body are provided with first locking plates. The surface of the first locking plate is provided with strip-shaped notches so as to fix it to the wall by bolts passing through the strip-shaped notches, or to fix the gypsum board by bolts passing through the strip-shaped notches and the gypsum board in sequence.

[0014] The frame body includes an upper plate and a lower plate. The first locking plate is respectively disposed on the adjacent surfaces of the upper plate and the lower plate. The side of the lower plate near the gypsum board has an outwardly protruding step edge. When the gypsum board is fixed on the lower plate, the lower end of the gypsum board is disposed on the surface of the step edge.

[0015] In a preferred embodiment, multiple support seats are arranged equidistantly within the lower plate, and each support seat is connected to the upper plate via an adjusting column.

[0016] The adjusting column includes a support bar, a locking tube, a threaded rod II, a telescopic rod, a spring, and a connecting block. The locking tube is sleeved on the outside of the threaded rod II and forms a threaded connection with the threaded rod II. The lower end of the threaded rod II is connected to the connecting block through the telescopic rod, and the connecting block is fixed to the surface of the support base. The spring is sleeved on the outside of the telescopic rod. The locking tube is connected to the upper plate body through a second locking plate provided at its upper end, and a second slot is also provided on the outside of the locking tube. The support bar is sleeved on the outside of the second slot.

[0017] The second locking plate has bolt holes on its surface.

[0018] A preferred technical solution is that the telescopic rod includes an inner tube and an outer tube, the outer tube being sleeved outside the inner tube, the inner tube being connected to the threaded rod two, and the outer tube being connected to the connecting block. A limiting strip extending along the length direction is provided on the outer side of the inner tube, and a sliding groove is provided in the outer tube corresponding to the limiting strip. The limiting strip abuts against the sliding groove. When the locking tube is rotated, the inner tube moves up and down with the threaded rod two.

[0019] A construction method for ceiling decoration and renovation, based on a scaffolding system for ceiling decoration and renovation, is characterized by comprising the following steps:

[0020] S1: Place the upper plate on the lower plate on which the adjusting column is installed, and fix the upper plate to the wall by passing the bolts through the support bar on the adjusting column and the first locking plate on the upper plate in sequence, and place the adjusting column against the ceiling surface at the construction site.

[0021] S2: Rotate the threaded rods on each adjusting column in sequence to adjust the position of the lower plate connected to the connecting block downwards until the lower plate is parallel to the horizontal line.

[0022] S3: Install the plasterboard onto the frame body, and lift the plasterboard by the step edge set at the lower end of the lower plate. Then, readjust each adjusting column to make the lower plate and plasterboard parallel to the horizontal line.

[0023] Compared with existing technologies, this technical solution has the following advantages:

[0024] In this invention, a scaffolding platform for construction workers to stand on can be assembled by means of a support member, a threaded telescopic rod, and a retainer. During use, more working space can be obtained by changing the length or size of the support member. After the work is completed, the threaded telescopic rod, retainer, and support member are removed in sequence, and the frame body is used as a skeleton to fix the plasterboard.

[0025] This invention fills the joint area between two gypsum boards with a sealant, which not only seals surface cracks but also significantly enhances the structural stability and overall rigidity of the joint area, thereby improving the long-term performance of the ceiling system. Specifically, when the sealant is pressed into the joint between the gypsum boards through the injection cavity and guide port of the edge repair strip, the material, guided by the inclined surface, fully fills the gap between the boards, forming a continuous and dense "structural sealant joint." After curing, this sealant joint has a certain tensile and shear strength, which can effectively restrain the relative displacement of the two gypsum boards and prevent the joint from opening or closing due to slight vibrations or changes in temperature and humidity.

[0048] like Figures 1 to 16 As shown, the present invention proposes a scaffold for building ceiling decoration and renovation construction, including a frame body 100 and a plurality of threaded telescopic rods 300 supported at the lower end of the frame body. Two adjacent threaded telescopic rods 300 are connected by a retainer 400. A support member 500 is fixed on the retainer 400. The support member 500 and the threaded telescopic rod 300 form an H-shaped connection.

[0049] The retaining member 400 includes a connector 401, a fastening member 402 and a fixing buckle 403. The connector 401 is sleeved on the threaded telescopic rod 300 through the fastening members 402 provided at both ends of it, and the fixing buckle 403 is fixed to the outside of the fastening member 402.

[0050] The threaded telescopic rod 300 includes a threaded rod and sleeves fitted on the upper and lower sides of the outer end of the threaded rod. Both sleeves are threadedly connected to the threaded rod, so that the distance between the two sleeves can be adjusted by rotating the threaded rod. The connecting piece 401 is fitted on the outside of the threaded rod.

[0051] The fastener 402 has an opening on its side. The fastener 402 is fitted onto the threaded rod through the opening. The side of the fastener 402 closest to the opening protrudes outward, and the fixing plate 403 is fitted onto the protrusion. As shown above, the frame body 100 can be fixed to the ceiling with rivets first, and the threaded telescopic rod 300, retainer 400 and support 500 can be installed in sequence to form a fixed scaffolding platform against the wall for construction workers to stand on. During use, more working space can be obtained by changing the length or size of the support 500. After the work is completed, the threaded telescopic rod 300, retainer 400 and support 500 can be removed in sequence, and the frame body 100 can be used as the skeleton for fixing the plasterboard 200.

[0052] The support member 500 includes a support plate 501 and a support rod 502 for supporting the support plate 501. The support plate 501 has a first recessed groove in the middle. The support plate 501 is connected to the retainer 400 through the first groove. The side of the support plate 501 near the support rod 502 extends outward. The side of the support plate 501 away from the support rod 502 is inclined and abuts against the wall surface.

[0053] Furthermore, a plasterboard 200 is installed on the frame body 100. Each bend on the outer edge of the frame body 100 is provided with an installation groove. An edge repair strip 3 is provided in the installation groove. The edge repair strip 3 is attracted to the frame body 100 by a magnetic plate 32 provided at its bottom. An inwardly extending injection cavity 31 is provided in the lower end of the edge repair strip 3, and the injection cavity 31 is connected to the outside through a guide port 311 provided on its side. The guide port 311 extends along the length direction of the edge repair strip 3.

[0054] The edge repair strip 3 is set with an inclined surface at one end near the guide port 311. Both ends of the gypsum board 200 extend to the inclined edge of the edge repair strip 3 on both sides. The gypsum board 200 is provided with a plurality of equidistant guide grooves 201 at the inclined surface near the edge repair strip 3. The guide port 311 is provided with an inwardly recessed step edge on the side near the guide groove 201. When two edge repair strips 3 are brought together at a 90° angle, the step edges on the two edge repair strips 3 form a flow channel, which is connected to the guide groove 201.

[0055] As shown above, when the two joint repair strips 3 meet at a 90° angle at the corner, the steps at the ends of their guide ports 311 interlock to form a closed flow channel, ensuring that the material filling the gap is stably transported under pressure. More importantly, the plasterboard 200 has multiple equidistant guide grooves 201 on the side near the joint repair strips 3. These guide grooves 201 are connected to the injection cavity 31 through the aforementioned flow channel, allowing the material filling the gap (such as wall paint, putty, etc.) to be squeezed out from the guide ports 311 to fill the main joint, while some of the material can be... The material flows in reverse into the guide channel 201 and solidifies, forming multiple internal "anchoring points," thereby tightly connecting the gypsum board 200, the edge joint repair strip 3, and the frame body 100 into a single unit, significantly improving the integrity and tensile strength of the joint area. In addition, since the edge joint repair strip 3 is fixed to the frame body 100 by magnetic attraction, and the gypsum board 200 is also installed on the same frame body 100, the two can achieve synchronous displacement when subjected to stress and deformation. Combined with the elastic buffering performance of the caulking material itself, stress concentration on a single joint line is avoided, which could lead to cracking.

[0056] Furthermore, the edge joint repair strip (3) described in this invention can be quickly replaced and repaired, is easy to operate, and does not affect the overall ceiling structure. The specific replacement steps are as follows: First, use a special tool (such as a scraper or suction cup) to smoothly remove the original edge joint repair strip 3 from the mounting groove of the frame body 100 in the horizontal direction. The magnetic plate 32 set at its bottom is detachably magnetically connected to the frame. The removal process does not require damage to the plasterboard 200 or the main keel structure. Then, clean the residual caulking material and dust in the mounting groove and surrounding area to ensure that the mounting surface of the new edge joint repair strip 3 is clean and flat. Next, align the new seam repair strip 3 with the mounting groove and secure it firmly using the magnetic plate 32. Ensure that the beveled surface of the flow port 311 is tightly fitted with the beveled end of the plasterboard 200, and check whether the steps of adjacent seam repair strips at the corners are aligned to form a continuous flow channel. Finally, inject caulking plaster or flexible sealant through the injection cavity 31. The material flows into the crack area between the boards through the flow port 311, and at the same time, some seeps into the guide groove 201 to form an anchoring structure. After curing, the joint repair is complete. This replacement operation does not require removing a large area of ​​wall paint or removing the plasterboard.

[0057] By filling the joint area between two gypsum boards 200 with caulking material, not only are surface cracks sealed, but the structural stability and overall rigidity of the joint area are also significantly enhanced, thereby improving the long-term performance of the ceiling system. Specifically, when the caulking material is pressed into the joint between the gypsum boards through the injection cavity 31 and the guide port 311 of the edge repair strip 3, the material, guided by the inclined surface, fully fills the gap between the boards, forming a continuous and dense "structural adhesive joint." After curing, this adhesive joint has a certain tensile and shear strength, which can effectively restrain the relative displacement of the gypsum boards on both sides and prevent the joint from opening or closing due to slight vibration or temperature and humidity changes. More importantly, some of the caulking material seeps back into the multiple guide ports 201 at the ends of the gypsum boards through the connecting channel between the guide port 311 and the guide groove 201, forming an independent "material anchor" in each guide groove.

[0058] The frame body 100 has a first locking plate 101 on both the upper and lower sides of its inner end. The surface of the first locking plate 101 has a strip-shaped notch, so that it can be fixed to the wall by bolts passing through the strip-shaped notch, or by bolts passing through the strip-shaped notch and the plasterboard 200 in sequence to fix the plasterboard 200. The frame body 100 includes an upper plate 1 and a lower plate 2. The first locking plates 101 are respectively set on the adjacent surfaces of the upper plate 1 and the lower plate 2. The side of the lower plate 2 near the plasterboard 200 has an outwardly protruding step edge. When the plasterboard 200 is fixed to the lower plate 2, the lower end of the plasterboard 200 is set on the surface of the step edge.

[0059] This structural design allows the gypsum board 200 to transfer its own weight and external load directly to the lower plate 2 via the step edge when subjected to vertical forces, effectively preventing the gypsum board 200 from sinking or slipping during installation or use. Simultaneously, because the step edge provides a stable lateral limiting reference, the gypsum board 200 is also constrained in the horizontal direction. Combined with the fixing of the gypsum board 200 by bolts passing through the first locking plate 101, the reliability of the connection is further enhanced. Therefore, as long as the lower plate 2 itself is firmly fixed to the wall by the first locking plate 101 without loosening or deformation, the step edge above it can continuously provide stable support for the gypsum board 200.

[0060] Furthermore, multiple support seats 21 are equidistantly arranged inside the lower plate 2, and each support seat 21 is connected to the upper plate 1 through an adjusting column 4. The adjusting column 4 includes a support bar 41, a locking tube 42, a threaded rod 43, a telescopic rod 44, a spring 45, and a connecting block 46. The locking tube 42 is sleeved outside the threaded rod 43 and forms a threaded connection with the threaded rod 43. The lower end of the threaded rod 43 is connected to the connecting block 46 through the telescopic rod 44, and the connecting block 46 is fixed to the surface of the support seat 21. The spring 45 is sleeved outside the telescopic rod 44. The locking tube 42 is connected to the upper plate 1 through a second locking plate 421 provided at its upper end, and a second slot 422 is also provided on the outside of the locking tube 42. The support bar 41 is sleeved outside the second slot 422. The surface of the second locking plate 421 is provided with bolt holes.

[0061] Furthermore, the telescopic rod 44 includes an inner tube 441 and an outer tube 442. The outer tube 442 is sleeved outside the inner tube 441, and the outer tube 442 is sleeved outside the outer tube 442. The inner tube 441 is connected to the threaded rod 43, and the outer tube 442 is connected to the connecting block 46. The outer side of the inner tube 441 is provided with a limiting strip 4411 extending along the length direction. The outer tube 442 is provided with a sliding groove corresponding to the limiting strip 4411. The limiting strip 4411 abuts against the sliding groove. When the locking tube 42 is rotated, the inner tube 441 moves up and down with the threaded rod 43.

[0062] By adjusting the telescopic rod 44 in column 4 in conjunction with the threaded structure, the height of the lower plate 2 and the gypsum board 200 fixed on it can be finely adjusted, thereby ensuring that the gypsum board 200 remains parallel to the horizontal line after installation. The specific adjustment process is as follows: the threaded rod 43 in column 4 is threadedly connected to the locking tube 42. When the locking tube 42 is rotated, since the locking tube 42 is fixed to the upper plate 1 through the second locking plate 421 at its upper end, and the second locking plate 421 is connected to the wall through bolts, the rotation of the locking tube 42 will drive the threaded rod 43 to move up and down axially. The lower end of the threaded rod 43 is connected to the connecting block 46 through the telescopic rod 44, and the connecting block 46 is fixed on the support seats 21 arranged at equal intervals inside the lower plate 2, thereby transmitting the movement to the lower plate 2, and thus adjusting the position of the lower plate 2 and the gypsum board 200.

[0063] Based on the above, this invention also proposes a construction method for ceiling decoration and renovation, based on the aforementioned scaffolding for ceiling decoration and renovation, characterized in that the construction method includes the following steps:

[0064] S1: Place the upper plate 1 on the lower plate 2 on which the adjusting column 4 is installed, and fix the upper plate 1 to the wall by passing the bolt through the support bar 41 on the adjusting column 4 and the first locking plate 101 on the upper plate 1 in sequence, and place the adjusting column 4 against the ceiling surface at the construction site.

[0065] S2: Rotate the threaded rods 43 on each adjusting column 4 in sequence to adjust the position of the lower plate 2 connected to the connecting block 46 downwards until the lower plate 2 is parallel to the horizontal line.

[0066] S3: Install the plasterboard 200 onto the frame body 100, and lift the plasterboard 200 by the step edge set at the lower end of the lower plate 2, and readjust each adjusting column 4 again so that the lower plate 2 and the plasterboard 200 are parallel to the horizontal line.

[0067] The above description is merely a preferred embodiment of the present invention, and therefore should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of the patent and the contents of the specification should still fall within the scope of the present invention.
