Description

Technical Field

[0001] The invention belongs to the technical field of decorative structures, and particularly relates to a back-strip type dry-hanging brick construction method. Background Art

[0002] The dry hanging method of stone, also known as the air hanging method, is a new type of construction technology in wall decoration. This method uses metal hangers to hang the decorative stone directly on the wall or hang it on the steel frame without grouting or pasting. The principle is to set the main stress points on the main structure and fix the stone to the building through metal hangers to form a stone decorative curtain wall.

[0003] Problems with existing technologies:

[0004] The installation of traditional dry-hanging tiles has a slow construction cycle. On-site processing generally uses angle iron and channel steel to weld the steel frame. A large amount of dry-hanging glue is filled between the vitrified tiles and the back bolts, making it impossible to disassemble and repair. At the same time, the uneven welding technology leads to welding point control and weld scar treatment, which affects the construction quality. The processing dust and waste garbage generated greatly affect the on-site construction environment. In addition, in the traditional hanging tile structure, there is no way to directly and clearly know the stress conditions of the directly stressed components, and thus it is impossible to determine whether all the weight during hanging is evenly distributed. Such problems will cause the compressive stress on a certain part to be too large and cannot be detected. What's worse, there is a possibility that a part will break. Summary of the Invention

[0005] The purpose of the present invention is to provide a back-strip dry-hanging brick construction method, which can shorten the installation period, make the construction simpler, more convenient and environmentally friendly, and also facilitate the determination of whether each galvanized angle iron is under stress.

The pressure blocks are also directly above the top block and in press contact with the surface of the top block.

[0010] Embedded steel plates are equidistantly arranged on both sides of the original ground structure, and the two embedded steel plates at the same height are connected by a through-screw that penetrates the original ground structure.

[0011] The outer walls of the embedded steel plates are all fixedly mounted with hot-dip galvanized angle irons, and the hot-dip galvanized angle irons are simultaneously fixedly mounted on the side walls of the thick galvanized square tubes.

[0012] The galvanized angle iron 1 is fixedly installed on the outer wall of the thick galvanized square tube by a through-screw 2 which penetrates the thick galvanized square tube.

[0013] Springs are connected between the two ends of the top block and the upper surfaces of the baffles on both sides.

[0014] An upper surface of one end of the side sliding body penetrating through the two side walls of the galvanized angle iron is provided with an inclined surface, and a chamfer is provided at the bottom of the top block where it contacts the inclined surface.

[0015] An adjustment cavity for adjusting the expansion bolt is provided in the middle of the galvanized angle iron.

[0016] A baffle is integrally fixed on the outer surface of one end of the prompt rod close to the fluorescent coating, and when the baffle contacts the housing, the prompt rod just passes through the end hole, and at this time the top of the prompt rod is flush with the upper surface of the back bolt hanger.

[0021] (2) The present invention determines whether the galvanized angle iron No. 2 at a certain location is under stress by observing whether the fluorescent coating can be observed. If the fluorescent coating is exposed, it is determined that the galvanized angle iron No. 2 at that location is not under the pressure of the back bolt hanger. Then, by adjusting the adjusting bolt, the galvanized angle iron No. 2 at that location shares the gravity from the vitrified tile surface layer, ensuring that the gravity brought by the vitrified tile surface layer can be shared by all the galvanized angle irons No. 2 at the same time, effectively avoiding the stress concentration in the galvanized angle iron No. 2 at a certain location and avoiding the accident of fracture due to excessive stress at a certain location.

[0032] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0033] like Figure 1-8 As shown, a back-strip dry-hanging brick construction method includes an original ground structure 1 and a vitrified tile surface layer 10. The front of the original ground structure 1 is fixedly installed with thick galvanized square tubes 5 in an array. The outer wall of the thick galvanized square tubes 5 is fixedly installed with galvanized angle irons 7 in an array. The back of the vitrified tile surface layer 10 is fixedly installed with back bolt hangers 11 in an array. The back of the vitrified tile surface layer 10 is fixedly installed with galvanized angle irons 8. The back bolt hangers 11 are hung on the top of the galvanized angle irons 8. The galvanized angle irons 8 and the back bolt hangers 11 are fixedly installed on the back of the vitrified tile surface layer 10 by expansion bolts 12. The positions of the galvanized angle irons 8 and the galvanized angle irons 7 correspond to each other and the two are connected by a through-through screw 9. The top of the back bolt hanger 11 is equidistantly screwed with adjustment bolts 13 for adjusting the relative position between the galvanized angle irons 8 and the back bolt hangers 11.

[0034] Refer to the attached Figure 2 and Figure 5 Embedded steel plates 2 are equidistantly arranged on both sides of the original ground structure 1, and the two embedded steel plates 2 at the same height are connected by a through screw 3 that penetrates the original ground structure 1. The outer walls of the embedded steel plates 2 are fixedly installed with hot-dip galvanized angle irons 4, and the hot-dip galvanized angle irons 4 are also fixedly installed on the side walls of the thick galvanized square tube 5. The galvanized angle iron 7 is fixedly installed on the outer wall of the thick galvanized square tube 5 by a through screw 6 that penetrates the thick galvanized square tube 5.

[0035] 10mm thick beige vitrified tiles, and the back of the vitrified tiles is fixed with 2.5mm thick full-length aluminum alloy back bolt hangers 11 and aluminum alloy galvanized angle irons 8. After the vertical keel thick galvanized square tube 5 and the connecting piece galvanized angle iron 7 are installed, the vitrified tiles are punched and the full-length back bolt hangers 11 are installed through expansion bolts 12 and then directly put on the wall. The verticality and level of the vitrified tiles can be quickly adjusted through the connecting pieces and adjusting bolts 13 at various parts. This installation method assembles the various parts needed in advance and then combines them for installation, eliminating the need for traditional vitrified tiles to measure and cut the parts at the construction site, shortening the installation period, making construction simpler and more convenient, and making the construction site cleaner and more beautiful. It will not generate too much decorative material waste and is a more environmentally friendly decorative construction form.

[0036] Refer to the attached Figure 7 and Figure 8 A functional cavity 802 is fixedly provided on the top of the galvanized angle iron 802, and baffles 803 are fixedly provided on both sides of the interior of the functional cavity 802. A top block 804 is slidably assembled inside the functional cavity 802, and springs 805 are connected between the two ends of the top block 804 and the upper surfaces of the baffles 803 on both sides. A side sliding body 806 is movably installed inside the functional cavity 802 and below the top block 804. An end of the side sliding body 806 extending to the outside of the galvanized angle iron 802 is provided with an end hole. A sleeve 807 is fixedly provided on one side of the top of the galvanized angle iron 802, and a prompt rod 808 is slidably assembled through the sleeve 807. The top outer surface of the prompt rod 808 is coated with a fluorescent coating 809 for workers to observe.

[0037] Refer to the attached Figure 7 and Figure 8 The upper surface of one end of the side sliding body 806 that passes through the side wall of the galvanized angle iron 28 is provided with a bevel, and the bottom of the top block 804 and the contact with the bevel are provided with a chamfer. The middle part of the galvanized angle iron 28 is provided with an adjustment cavity 801 for adjusting the expansion bolt 12. The outer surface of the end of the prompt rod 808 close to the fluorescent coating 809 is integrally fixed with a baffle, and when the baffle contacts the sleeve 807, the prompt rod 808 just passes through the end hole, and at this time, the top of the prompt rod 808 is flush with the upper surface of the back bolt hanger 11.

[0038] Refer to the attached Figure 6 and Figure 7The upper surface of the back bolt hanger 11 is equidistantly penetrated with through holes 1101, and a pressure block 1103 is equidistantly installed inside the back bolt hanger 11 and located directly below the adjusting bolt 13. The pressure block 1103 is also located directly above the top block 804 and is in extrusion contact with the surface of the top block 804. Side slot holes 1102 are penetrated on both side walls of the back bolt hanger 11 and corresponding to the installation position of the pressure block 1103, and both ends of the pressure block 1103 are fixedly connected with side rods 1104, and the side rods 1104 are movably penetrated through the side slot holes 1102.

[0039] Refer to the attached Figure 7 and Figure 8 The prompt rod 808 corresponds to the position of the through hole 1101 and the top end of the prompt rod 808 is movable and passes through the through hole 1101.

[0040] According to the above structure, when the vitrified tile surface layer 10 is hung together with the back bolt hanger 11 and the galvanized angle iron 2 8, each galvanized angle iron 2 8 is aligned with the corresponding galvanized angle iron 1 7, and then the galvanized angle iron 2 8 and the galvanized angle iron 1 7 are fixed by the through screw 3 9, thereby completing the hanging work of the vitrified tile surface layer 10. After the vitrified tile surface layer 10 is vertically erected, when the corresponding galvanized angle iron 2 8 at a certain place is not subjected to force, the pressing block 1103 and the top block 804 are in contact but no extrusion occurs. At this time, the side sliding body 806 will be located inside the galvanized angle iron 8, the prompt rod 808 will be blocked by the side sliding body 806, and the top end containing the fluorescent coating 809 will pass through the through hole 1101 and extend to the top of the back bolt hanger 11. The setting of the fluorescent coating 809 is easy to detect during work. When the installer finds that the fluorescent coating 809 at a certain place is not hidden inside the back bolt hanger 11 as expected, at this time, the adjusting bolt 13 at that place is rotated, and the pressure block 1103 will be driven to move downward and squeeze the top block 804. During this process, the side rod 1104 will As it moves along the side slot 1102, the top block 804 will retract into the top of the galvanized angle iron 8 and squeeze the spring 805 at the same time. Then, due to the compression of the chamfered bottom of the top block 804 and the inclined surface of the upper surface of the side sliding body 806, the side sliding body 806 will slide sideways. When the end hole at one end of the side sliding body 806 is completely placed outside the galvanized angle iron 8, the prompt rod 808 will just pass through the end hole and the fluorescent coating 809 will just be hidden inside the back bolt hanger 11. Whether the fluorescent coating 809 can be observed 09 is used to determine whether the galvanized angle iron 8 at a certain place is under stress. When the fluorescent coating 809 is exposed, it is determined that the galvanized angle iron 8 at that place is not under the pressure of the back bolt hanger 11. Then, by adjusting the adjusting bolt 13, the galvanized angle iron 8 at that place shares the gravity from the vitrified tile surface layer 10, ensuring that the gravity brought by the vitrified tile surface layer 10 can be shared by all the galvanized angle irons 8 at the same time, effectively avoiding the stress concentration of the galvanized angle iron 8 at a certain place, and avoiding the accident of fracture due to excessive stress at a certain place.

[0041] The working principle of the present invention is as follows: the traditional dry-hanging installation of vitrified tiles is changed to a back-strip dry-hanging installation of vitrified tiles. 6# channel steel is used for welding the vertical thick galvanized square tube 5. The vitrified tile surface layer 10 is a 10mm thick beige vitrified tile. The back of the vitrified tile is fixed with a 2.5mm thick full-length aluminum alloy back bolt hanger 11 and an aluminum alloy galvanized angle iron 8. After the vertical thick galvanized square tube 5 and the connecting galvanized angle iron 7 are installed, the vitrified tile is punched and the full-length back bolt hanger 11 is installed with expansion bolts 12, and then it is directly mounted on the wall. The verticality and horizontality of the vitrified tile can be quickly adjusted through the connecting parts and adjustment bolts 13 at various parts.

[0042] When the vitrified tile surface layer 10 is hung together with the back bolt hanger 11 and the galvanized angle iron 2 8, each galvanized angle iron 2 8 is aligned with the corresponding galvanized angle iron 1 7, and then the galvanized angle iron 2 8 and the galvanized angle iron 1 7 are fixed by the through screw 3 9, thereby completing the hanging of the vitrified tile surface layer 10. After the vitrified tile surface layer 10 is vertically erected, when the corresponding galvanized angle iron 2 8 at a certain place is not subjected to force, the pressing block 1103 and the top block 804 are in contact but not squeezed. At this time, the side sliding body 806 will be located inside the galvanized angle iron 2 8, and the prompt rod 808 will be blocked by the side sliding body 806, and the top end containing the fluorescent coating 809 passes through the through hole 1101 and extends to the top of the back bolt hanger 11. The setting of the fluorescent coating 809 is easy to detect during work. When the installer finds that the fluorescent coating at a certain place is 809 is not hidden inside the back bolt hanger 11 as expected. At this time, by rotating the adjusting bolt 13 there, the pressure block 1103 will be driven to move downward and squeeze the top block 804. During this process, the side rod 1104 will move along the side slot hole 1102, and the top block 804 will retract into the interior of the top of the galvanized angle iron 2 8 and squeeze the spring 805 at the same time. Then, due to the compression of the chamfer at the bottom of the top block 804 and the inclined surface of the upper surface of the side sliding body 806, the side sliding body 806 will slide sideways. When the end hole at one end of the side sliding body 806 is completely placed outside the galvanized angle iron 2 8, the prompt rod 808 will just pass through the end hole and the fluorescent coating 809 will just be hidden inside the back bolt hanger 11. Whether the galvanized angle iron 2 8 at a certain place is subjected to force can be determined by whether the fluorescent coating 809 can be observed.
