Description

Technical Field

[0001] The invention relates to the field of scaffolds, in particular to a scaffold structure for building exterior wall construction. Background Art

[0002] As an important temporary construction facility, the structural excellence of the scaffolding is nothing more than its firmness and ease of assembly and disassembly. The scaffolding is roughly divided into two types: attached scaffolding and ground-based scaffolding. Whether it is an attached scaffolding or a ground-based scaffolding, the main body is composed of a large number of vertical poles, horizontal poles and even diagonal braces, among which the common ones include clip-on scaffolding, disc-type scaffolding and bowl-type scaffolding.

[0003] As for the types of scaffolding mentioned above, the clip-on scaffolding is eccentrically connected and has a weaker bearing capacity, so it is gradually replaced by the disc-type and bowl-type scaffolding;

[0004] Whether it is a clip-on type, a disc-on type or a bowl-on type, in order to facilitate the disassembly and assembly of the scaffolding, the fasteners that mainly play a connecting role are all located on the outside of the vertical poles. Although more anti-corrosion measures are adopted, such as anti-corrosion coatings, etc., for more delicate structural parts such as clips, on the one hand, the adoption of anti-corrosion measures undoubtedly requires a large cost. On the other hand, the delicate structure is affected by external environmental factors and suffers a high degree of corrosion, resulting in an extremely high loss rate, which is not economical enough. For this reason, we propose a scaffolding structure for building exterior wall construction. Summary of the invention

[0005] [Technical issues solved]

[0016] Preferably, the fitting plate and the outer guard plate are integrally formed.

[0019] Preferably, a slot two is provided on the inner side of the outer guard plate at a position corresponding to the fitting seat one, and the fitting plate is detachably connected to the outer guard plate through the fitting seat one and based on the through hole two, and a bolt assembly is provided therebetween for adjusting the distance between the fitting plate and the outer guard plate. Because the fitting plate is connected to the outer guard plate based on the fitting seat one and the slot two, during use, more load is borne by the outer guard plate.

[0020] Preferably, the fitting seat 1 is provided with a mounting hole transversely, and the mounting hole is used to place a nut. During the assembly process, the nut can be prevented from falling off on the inner side of the vertical pole.

[0032] Preferably, the crossbar is replaced by a square tube.

[0033] Preferably, screw rods for reinforcing the connection are arranged inside the two connected vertical poles, and at least one of the two connected vertical poles is provided with a threaded seat threadably connected to the screw rod.

[0034] Preferably, the threaded seat is welded to the inner wall of the vertical pole.

[0035] Preferably, the screw rod is a double-head screw rod, in which case the inner walls of the two connected vertical rods are both provided with a threaded seat which is threadably connected to the screw rod.

[0036] Preferably, a limit seat is attached to the inner wall of the upper vertical rod, serving as a fixing reference for the screw rod.

[0037]

Beneficial Effects

[0038] Compared with the prior art, the present invention provides a scaffolding structure for building exterior wall construction, which has the following beneficial effects:

[0039] The scaffolding structure for building exterior wall construction is connected, reinforced and protected by two vertical poles of an outer guard plate. Because the outer guard plate covers the connection between the two vertical poles, it not only provides additional physical support between the vertical poles and the horizontal poles, but also effectively reduces the risk of loose connection caused by external force impact or long-term vibration, and indirectly simplifies daily inspection and maintenance work;

[0040] After the two uprights are fully connected with the outer guard plate, similar to the mortise and tenon structure, the fitting plate located on the inner side of the upright constitutes the radial movement restriction of the outer guard plate based on the upright, and the limit groove opened on the outer guard plate and the limit ring opened on the outer wall of the upright constitute the axial movement restriction between the two uprights, thereby ensuring the geometric dimensional accuracy of the scaffolding after the overall assembly, making the scaffolding more regular, stable and beautiful;

[0041] Furthermore, since the structural components that mainly serve to connect and fix are not located on the outside, they can be protected from erosion by external environmental factors during actual use, which indirectly extends the service life of the scaffolding materials;

[0042] In addition, this connection method allows for more efficient assembly of vertical poles and horizontal poles, further reducing on-site construction time, improving overall construction efficiency, and correspondingly effectively reducing the possibility of scaffolding assembly errors.

[0068] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0069] [Example 1]

[0070] In order to address the shortcomings of the existing technology, such as Figure 1As shown, the present invention provides a scaffolding structure for building exterior wall construction. To meet the grooving requirements of the vertical pole 1, the wall thickness should be controlled within 3.7 mm to 4.8 mm, and can be thicker.

[0071] It should be noted that those skilled in the art can understand that in the process of assembling the scaffolding, if it involves the wall thickness of the steel pipe, load calculation, etc., whether the scaffolding structure of the present invention is applied to an attached scaffolding or a ground-based scaffolding, etc., it should be strictly implemented in accordance with the relevant national standards and industry standards and other normative documents, and no further elaboration will be made in this embodiment.

[0072] Specifically, Figures 2~5 As shown, a vertical pole 1 and an outer guard plate 3 in a scaffolding structure for building exterior wall construction, a limiting ring 11 is a threaded steel bar, which is bent and welded to the outer wall of the vertical pole 1; the limiting ring 11 can be replaced by a flange 11-1, and the flange 11-1 is expanded by a tube shrinking machine or a tube expander; the through groove 12 is formed by cutting, or the vertical pole 1 is cast as a whole by a mold; the inner pipe 13 is formed by a tube shrinking machine;

[0073] The size of the limiting groove 32 is one quarter of the size of the limiting ring 11 , and the structure of the limiting groove 32 matches that of the limiting ring 11 ; the matching plate 31 and the outer guard plate 3 are formed in one piece.

[0074] It should be noted that the present invention is a scaffolding structure for building exterior wall construction. Through the provided upright poles 1 and outer guard plates 3, during the assembling process of the scaffolding, it is necessary to first insert the outer guard plates 3 attached to the cross bars 2 to be installed into the upper part of the upright poles 1:

[0075] Because the fitting plate 31 and the outer guard plate 3 are detachably connected by bolts, during the installation process, due to the structure of the through groove 12, it is necessary to first insert the fitting plate 31 into the inner side of the upper part of the vertical pole 1, and then make the fitting seat 312 attached to the fitting plate 31 face the through groove 12, and then place the outer guard plate 3 attached to it on the outer side corresponding to the upper part of the vertical pole 1, and fix them together by bolts.

[0076] Then, after the outer guard plate 3 attached to the crossbar 2 to be installed is connected to the vertical pole 1, another vertical pole 1 to be plugged in is plugged into the upper end of the previous vertical pole 1:

[0077] In the process of plugging in another vertical pole 1 located above, it is necessary to push the outer guard plate 3 in the axial direction relative to the vertical pole 1, such as Figure 4In the structural state shown, when the two uprights 1 are completely connected, the fitting plates 31 attached to the outer guard plate 3 should be located on the inner side of the upper upright 1, thereby constituting a radial movement restriction based on the upright 1. At the same time, the two limit grooves 32 opened on the outer guard plate 3 are respectively covered on the outer side of the corresponding limit rings 11, thereby constituting an axial movement restriction of the upright 1 based on the outer guard plate 3.

[0078] It is worth mentioning that the two vertical poles 1 are connected, reinforced and protected by the outer guard plate 3. Since the outer guard plate 3 covers the connection between the two vertical poles 1, it not only provides additional physical support between the vertical poles 1 and the crossbar 2, but also effectively reduces the risk of loose connection caused by external impact or long-term vibration, and indirectly simplifies daily inspection and maintenance work;

[0079] After the two uprights 1 are completely connected with the outer guard plate 3, similar to the mortise and tenon structure, the fitting plate 31 located on the inner side of the upright 1 constitutes the radial movement restriction of the outer guard plate 3 based on the upright 1, and the limit groove 32 opened on the outer guard plate 3 and the limit ring 11 opened on the outer wall of the upright 1 constitute the axial movement restriction between the two uprights 1, thereby ensuring the geometric dimensional accuracy of the scaffold after the overall assembly, making the scaffold more regular, stable and beautiful;

[0080] Furthermore, since the structural components that mainly serve to connect and fix are not located on the outside, they can be protected from erosion by external environmental factors during actual use, which indirectly extends the service life of the scaffolding materials;

[0081] In addition, with this connection method, the vertical poles 1 and the horizontal poles 2 can be assembled more efficiently, further reducing the construction time on site, improving the overall construction efficiency, and correspondingly effectively reducing the possibility of scaffolding assembly errors.

[0082] As a preferred embodiment, specifically, Figure 3 , 4 As shown, an outer guard plate 3 in a scaffolding structure for building exterior wall construction, the retracted section 311 is formed by opening a fitting plate 31, or is integrally cast.

[0083] It should be noted that the present invention is a scaffolding structure for building exterior wall construction. By setting the outer guard plate 3, the upper part of the inwardly contracted section 311 of the mating plate 31 is inwardly contracted toward the axis of the vertical pole 1. In the process of plugging the two vertical poles 1, the vertical pole 1 can be more accurately plugged into the mating plate 31 to apply force.

[0084] As an ideal structural state, those skilled in the art can understand that Figure 4In the structural assembly state shown, during the process of plugging in the upper vertical pole 1, the upper vertical pole 1 directly applies force to the outer guard plate 3 through the fitting plate 31. When the upper vertical pole 1 is plugged in vertically downward, the relatively erected outer guard plate 3 moves relative to each other synchronously. When the upper vertical pole 1 is plugged in and aligned with the vertical pole 1 located below, the limit groove 32 should be exactly matched with the limit ring 11.

[0085] Among them, Figure 4 As shown, based on this ideal operating state, since the relative movement of the upper pole 1 and the outer guard plate 3 is not in the same direction, the compensation edge 321 is to ensure that the outer guard plate 3 can smoothly connect with the pole 1 through the limit ring 11 based on the compensation gap formed by the compensation edge 321 during the insertion process of the pole 1;

[0086] In addition, after the assembly of one set of vertical poles 1 and outer guard plates 3 is completed, in order to facilitate the assembly of another set of vertical poles 1 and outer guard plates 3, technicians in this field can understand that, according to the actual assembly situation, it is possible to choose to loosen the bolts used to connect the outer guard plates 3 and the mating plates 31, so that the mating plates 31 can move to a small extent based on the radial direction of the outer guard plates 3 but not completely detach. In this way, after several sets of vertical poles 1 are connected, the bolts are tightened to ensure that the connection between the vertical poles 1 and the cross bars 2 is firm.

[0087] In this embodiment, it can be understood by those skilled in the art that, in the actual erection process, the lower end of the support pole 1 located at the lowest layer should be flattened or equipped with other external fixing measures and placed on the ground support to ensure the basic support stability of the scaffolding. In addition, in order to further ensure the waterproofness of the scaffolding, the unused second through groove 12 on the support pole 1 located at the corner side should be sealed to prevent rainwater from entering the interior of the support pole 1 during use.

[0088] In addition, the outer guard plate 3 can be always hung on the vertical pole 1 based on the fitting plate 31 attached to it, which is convenient for transportation and prevents loss. During the assembly process, the distance between the fitting plate 31 and the outer guard plate 3 is adjusted by rotating the bolts to achieve engagement with the vertical pole 1.

[0089] As a preferred embodiment, specifically, Figure 3 As shown, an outer guard plate 3 in a scaffolding structure for building exterior wall construction, because the fitting plate 31 is based on the fitting seat 1 312 and the slot 2 33 to dock with the outer guard plate 3, during use, more loads are borne by the outer guard plate 3;

[0090] The fitting seat 1 312 is laterally provided with an installation hole 313, and the installation hole 313 is used to place the nut 333. During the assembly process, the nut 333 can be prevented from falling off on the inner side of the vertical rod 1. The fitting seat 1 312 is provided with a through hole 1 314 connected to the installation hole 313, and the through hole 1 314 is opposite to the through hole 2 331 formed on the outer guard plate 3.

[0091] [Example 2]

[0092] The difference between the ground-type scaffolding and the attached scaffolding is that the arrangement of the vertical poles and horizontal poles required for the ground-type scaffolding is more dense, and the number of vertical poles and horizontal poles required is also more. Therefore, in the process of assembly, it is necessary to consider the convenience of assembling the scaffolding structure, and the ground-type scaffolding, apart from other loads, bears its own weight load basically from top to bottom. Therefore, based on the above-mentioned embodiment 1, in order to improve the convenience of assembling the scaffolding structure, this embodiment is proposed:

[0093] Specifically, Figure 6 , 7 As shown, a vertical pole 1 in a scaffolding structure for building exterior wall construction, a through groove 12 extends upward to form an open groove 12-1, and the open groove 12-1 is consistent with the structure of the second fitting seat 312-1.

[0094] It should be noted that the present invention is a scaffolding structure for the construction of the exterior wall of a building. Through the vertical pole 1, since the open groove 12-1 is an open design, during the assembly of the outer guard plate 3, the outer guard plate 3 can be directly plugged into the corresponding open groove 12-1 based on the fitting seat 2 312-1 attached thereto, and then one of the vertical poles 1 located above can be plugged into the other vertical pole 1 located below.

[0095] Among them, by replacing the through groove 12 with an open groove 12-1, the overall assembly convenience of the scaffolding structure is improved, and the fitting seat 1 312 is replaced by the fitting seat 2 312-1. The structural size of the fitting seat 2 312-1 becomes larger. Relatively speaking, the load-bearing capacity of the outer guard plate 3 is stronger. This embodiment is more suitable for ground-type scaffolding.

[0096] It is worth mentioning that the outer guard plate 3 is directly plugged into the vertical pole 1 from top to bottom through the fitting seat 2 312-1 based on the open groove 12-1, which simplifies the assembly process to the greatest extent. At the same time, the larger fitting seat 2 312-1 indirectly increases the contact area between the outer guard plate 3 and the vertical pole 1, making the structural connection of the scaffolding more secure.

[0097] It will be understood by those skilled in the art that Fig. 9In the structural state shown, the lower section of the vertical pole 1 can be formed by a square tube shrinking machine or by welding square tubes with a shrunken square tube 1-1. During the assembly process, the upper vertical pole 1 can be butt-jointed with the side edges 1-11 on the shrunken square tube 1-1 attached to its lower section and the open groove 12-1 on the lower vertical pole 1.

[0098] [Example 3]

[0099] Based on the above embodiments, in order to further improve the convenience of scaffold assembly, this embodiment is proposed:

[0100] Specifically, Figure 8 As shown, a crossbar 2 in a scaffolding structure for building exterior wall construction, the connector 21 is an I-beam welded to the outer guard plate 3; to ensure that the crossbar 2 is erected horizontally enough, the height difference between the two connectors 21 should be relative to the wall thickness of the crossbar 2.

[0101] It should be noted that the present invention is a scaffolding structure for building exterior wall construction. Through the provision of the cross bar 2, during the assembly of the cross bar 2, the two outer guard plates 3 to be installed at both ends of the cross bar 2 are first plugged in from bottom to top and from top to bottom through the connectors 21 thereon based on the slots 22 opened on the two side sections of the cross bar 2, and then the two outer guard plates 3 are respectively assembled to the corresponding vertical poles 1.

[0102] It is worth mentioning that the quick-release design is formed by connecting the left and right ends of the cross bar 2 with the connectors 21 in different directions and the slot 22. On the one hand, it simplifies the disassembly and assembly process while ensuring the structural strength, thereby reducing the labor cost. On the other hand, because the structural precision of the connector 21 and the slot 22 is not as good as that of bolts or clips, it is more convenient in the subsequent maintenance process, indirectly reducing the consumption of low-utilization materials, which is in line with the concept of sustainable development.

[0103] As a preferred embodiment, the cross bar 2 is replaced by a square tube 2-1. Compared with the traditional round or special-shaped cross bars, the square tube 2-1 has better rigidity and stability. Especially when bearing horizontal loads, the uniform force distribution on the four sides of the square tube 2-1 can effectively prevent twisting and deformation, thereby improving the anti-overturning ability of the entire scaffolding.

[0104] [Example 4]

[0105] Based on the above embodiments, in order to further improve the structural stability of the scaffolding, this embodiment is proposed:

[0106] Specifically, Fig.10As shown, a vertical pole 1 in a scaffolding structure for building exterior wall construction, a threaded seat 14 is welded to the inner wall of the vertical pole 1; the screw rod 4 is a double-headed screw rod, and at this time, the inner walls of the two connected vertical poles 1 are both provided with a threaded seat 14 threadedly connected to the screw rod 4; the inner wall of the vertical pole 1 located at the top is provided with a limit seat 15 as a fixed reference for the screw rod 4.

[0107] It should be noted that the present invention is a scaffolding structure for building exterior wall construction. By setting up the vertical pole 1, in order to further ensure the firmness of the connection between the two vertical poles 1, during the process of assembling the scaffolding, a screw 4 is inserted into the upper vertical pole 1, and the screw 4 is screwed into the threaded seat 14, and the end of the screw 4 is restricted by the limit seat 15, thereby forming a second guarantee for the connection of the scaffolding structure.

[0108] In the above embodiments, although the manufacturing process may require the support of specific equipment (such as a tube shrinking machine, a cutting machine, etc.), in the long run, by simplifying the assembly process, reducing on-site adjustment time and improving material utilization, the overall construction cost can be effectively reduced and the economic benefits of the project can be maximized.

[0109] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for illustrating the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed for protection.
