Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to an assembled precast ecological board composite thermal insulation exterior wall. Background Technique

[0002] At present, people's awareness of energy conservation and saving has been gradually deepened. Especially in building construction, energy conservation has become a key point in construction work, and energy-saving buildings have emerged as the times require. And building exterior wall energy-saving insulation has become an extremely important construction technology. The building exterior wall is the main medium for heat exchange between the indoor and outdoor of the building, and more than half of it is achieved through the heat insulation performance of the building envelope exterior wall. The indoor temperature difference between using an energy-saving exterior wall and using an ordinary exterior wall can reach 4-10 degrees. Therefore, the energy-saving design of the wall is an aspect that cannot be ignored.

[0003] When the existing assembled precast ecological board composite thermal insulation exterior wall is under construction and installation, it is usually installed by stacking precast thermal insulation boards and then welding them to each other. In the case of a large exterior wall area, the excessively stacked thermal insulation boards will accumulate too much gravity, and finally the thermal insulation boards at the lower part will be compressed and deformed or even crushed by extrusion, affecting the thermal insulation system of the building. Summary of the Invention

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0015] An assembled prefabricated ecological board composite thermal insulation exterior wall disclosed by the present invention is mainly applied to the scenario where the existing thermal insulation boards are excessively stacked during installation, causing the lower thermal insulation boards to be damaged due to compression.

[0016] Referring to Figures 1-9 , an assembled prefabricated ecological board composite thermal insulation exterior wall includes two symmetric steel columns 1. Between the two steel columns 1, there is a thermal insulation board 2. And on the outside of the two thermal insulation boards 2, there are an outer leaf board 3 and an inner leaf board 4. On the side of the thermal insulation board 2 close to the inner leaf board 4, there is a steel section frame 6. On the side of the thermal insulation board 2 close to the outer leaf board 3, there is an angle steel frame cover 5. The opposite sides of the steel section frame 6 and the angle steel frame cover 5 are connected by bolts. And on both the outer leaf board 3 and the inner leaf board 4, there are a plurality of symmetric quick disassembly and assembly modules 8. On both the steel columns 1, there are transverse pressure equalizing modules 7.

[0017] Specifically, after placing the insulation board 2 on the steel section frame 6, place the angle steel frame cover 5 on the insulation board 2 and complete welding with the steel section frame 6. Then place the formed integral insulation board 2 between two steel columns 1. Use the transverse pressure equalizing module 7 to horizontally fix the insulation board 2 on the steel columns 1, so that the steel columns 1 bear the weight of the integral formed by the insulation board 2, the angle steel frame cover 5 and the steel section frame 6. After the insulation board 2 is fixed, cover the outer leaf plate 3 and the inner leaf plate 4 on the outside of the insulation board 2 and the steel columns 1 and use the quick disassembly and assembly module 8 for quick installation. When it is necessary to replace the outer leaf plate 3 or the inner leaf plate 4, use the quick disassembly and assembly module 8 again to quickly disassemble the outer leaf plate 3 or the inner leaf plate 4; the device can effectively utilize the strength of the steel columns 1 to support the insulation board 2 installed on the building by using the transverse pressure equalizing module 7, thereby effectively reducing the influence of the weight generated by the stack of multiple vertically installed insulation boards 2 on the insulation board 2 located at the lower part, avoiding the situation where the insulation board 2 is crushed due to pressure, and ensuring the integrity and service function of the building insulation layer.

[0018] Refer to Figure 3 , Figure 4 , Figure 5 and Figure 6, in a preferred embodiment, the transverse pressure equalizing module 7 includes a transverse pipe 701. There is the same orifice on the profiled steel frame 6 and the heat preservation board 2. The inner wall of the orifice on the profiled steel frame 6 is bolted with the transverse pipe 701. The transverse pipe 701 is slidably connected with the inner wall of the orifice on the heat preservation board 2. A movable rod 703 is slidably connected in the transverse pipe 701. A circular groove 704 is formed in the inner wall of one end of the transverse pipe 701 close to the heat preservation board 2. A disc 705 is slidably connected in the circular groove 704. One side of the disc 705 opposite to the movable rod 703 is bolted. And a first spring 706 is wound around the outside of the movable rod 703. One end of the first spring 706 is bolted with the outside of the disc 705, and the other end is bolted with the inner wall of one side of the circular groove 704 far from the disc 705; Fine holes are formed in the sides of the steel columns 1 far from the inner leaf plate 4. Rotating rods 707 are rotatably connected in the fine holes through bearings. Support seats 708 are rotatably connected to the outside of the rotating rods 707 through bearings. One side of the support seats 708 opposite to the inner wall of the steel columns 1 is bolted. One end of the rotating rod 707 far from the steel column 1 is bolted with a first gear 709. And fine openings are formed in the sides of the two steel columns 1 close to the heat preservation board 2 and far from the heat preservation board 2. The inner wall of the fine hole of the steel column 1 close to the heat preservation board 2 is slidably connected with the outside of the movable rod 703. A first notched ring 711 is rotatably connected to the inner walls of the two steel columns 1 through bearings. The first notched rings 711 are all located outside the movable rod 703. Second gears 712 are bolted to the outside of the first notched rings 711. The second gears 712 are all meshed with the first gears 709 on the same side; Support brackets 714 are arranged outside the second gears 712. The support brackets 714 are located outside the movable rod 703. One side of the support brackets 714 opposite to the inner wall of the steel column 1 on the same side is bolted. Symmetric second notched rings 713 are arranged on the upper sides of the first notched rings 711. Cuts 715 are formed in the outside of the support brackets 714. Slide plates 716 are slidably connected in the cuts 715. The slide plates 716 are bolted with the outside of the second notched rings 713 on the same side. A second spring 717 is bolted to the opposite sides of the slide plates 716 and the cuts 715. And the first notched rings 711 and the second notched rings 713 are all located inside the support brackets 714. Two symmetric grooves are formed in the outside of the movable rod 703. Clamping blocks 718 are slidably connected in the grooves. A third spring 719 is bolted to the opposite sides of the clamping blocks 718 and the inner walls of the grooves. The two clamping blocks 718 are in contact with the outside of the second notched ring 713 on the same side;The inner walls of the steel columns 1 are all connected with fixing frames 702 by bolts. The inner walls of the fixing frames 702 are all connected with mounting seats 710 by bolts. The inner walls of the mounting seats 710 are all slidably connected with the outer parts of the movable rods 703. Three chutes 721 evenly distributed in a circumferential manner are opened on one side of the mounting seat 710 close to the bearing bracket 714. Positioning rods 722 are all slidably connected in the chutes 721. One side of the positioning rod 722 close to the bearing bracket 714 is all connected with a short shaft 723 by bolts. And one side of the mounting seat 710 close to the bearing bracket 714 is all rotatably connected with a rotating frame 724 by bearings; Three curved surface grooves 725 evenly distributed in a circumferential manner are opened on the rotating frame 724. The inner walls of the curved surface grooves 725 are all slidably connected with the outer parts of the short shafts 723 on the same side. And the rotating frames 724 are all located outside the movable rods 703. An annular groove 720 is opened on the movable rod 703. The inner wall of the annular groove 720 is all clamped with the outer parts of the three positioning rods 722 on the same side. And the inner walls of the rotating frames 724 are all connected with torsion springs 726 by bolts. One end of the torsion spring 726 far from the rotating frame 724 is all connected with the outer part of the mounting seat 710 on the same side by bolts.;

[0019] Specifically, place the insulation board 2 between the two steel columns 1. Align the movable rod 703 in the transverse pipe 701 with the fine holes on the steel column 1 and insert it. Under the pressure of the inner wall of the fine hole, the clamping block 718 retracts against the elastic force of the spring three 719, so that the notch ring two 713 can smoothly pass through the notch ring one 711 and the notch ring two 713 in the fitting state. After passing through the notch ring one 711 and the notch ring two 713, the elastic force of the spring three 719 pops out the clamping block 718, so that the clamping block 718 is clamped with the outer part of the notch ring two 713. Use a flat-tip screwdriver to rotate the rotating rod 707. The rotating rod 707 drives the gear one 709 to rotate. Thus, the gear two 712 meshing with the gear one 709 drives the notch ring one 711 to rotate 180 degrees. The notch ring two 713 gradually moves to a position symmetrical to the notch ring one 711 under the prying of the inclined surface of the notch ring one 711. Thus, the notch ring two 713 pushes the clamping block 718 to drive the movable rod 703 to penetrate deeper into the steel column 1, so that the movable rod 703 can be inserted into the mounting seat 710. One end of the movable rod 703 entering the mounting seat 710 pushes the positioning rod 722 away from the axis of the mounting seat 710 after contacting the positioning rod 722, so that the movable rod 703 can continue to enter the mounting seat 710. After the notch ring one 711 rotates 180 degrees, the movable rod 703 stops moving. At this time, the annular groove 720 and the positioning rod 722 are on the same side plane. Under the torsion of the torsion spring 726, the curved surface groove 725 on the rotating frame 724 rotates. Thus, the inner wall of the curved surface groove 725 pushes the short shaft 723 and drives the positioning rod 722 to move towards the axis of the mounting seat 710. Finally, the positioning rod 722 is clamped with the annular groove 720, and the movable rod 703 is fixed on the steel column 1.

[0020] In a specific application scenario, the horizontal pressure equalizing module 7 is mainly applicable to the horizontal pressure equalizing link during the horizontal pressure equalizing process. That is, the horizontal pressure equalizing module 7 uses the horizontal pipe 701 and the movable rod 703 to penetrate the whole formed by the insulation board 2, the angle steel frame cover 5 and the profiled steel frame 6, so that the steel column 1 with higher strength can share the weight of the continuously stacked insulation board 2, thus ensuring the stability of the entire building wall, reducing the risk of the insulation layer falling off or even collapsing due to weight imbalance, and improving safety.

[0021] It should be noted that the rotating rod 707 is used to drive the first notch ring 711 to rotate. The rotating rod 707 is installed by drilling a small hole in the steel column 1, so that the overall strength of the steel column 1 as the main load-bearing structure is not affected, ensuring the normal use function of the steel column 1.

[0022] The quick disassembly and assembly module 8 includes a plurality of notches 801. A plurality of symmetric notches 801 are formed on the outer vane 3 and the inner vane 4. A connecting frame 803 is connected to each notch 801 through a bolt. The inner walls of the connecting frames 803 are connected to a cover plate 804 through hinges. And a fixing frame 802 is connected to the side of the connecting frame 803 away from the cover plate 804 through a bolt. The outside of the fixing frame 802 and the inner wall of the notch 801 are both connected through bolts; A plurality of symmetric circular notches 819 are formed on the steel column 1. The circular notches 819 and the notches 801 on the same side are located on the same axis. A groove-shaped ring 805 is connected to the inner wall of the fixing frame 802 through a bolt. A rough surface groove 807 is formed on the side of the groove-shaped ring 805 close to the cover plate 804. And a sleeve 818 is slidably connected to the inner wall of the groove-shaped ring 805. A collar 806 is connected to the side of the sleeve 818 close to the cover plate 804 through a bolt. The side of the collar 806 away from the cover plate 804 is slidably connected to the outside of the rough surface groove 807 on the same side; A threaded groove 809 is formed on the outside of the sleeve 818. A knob 810 is arranged on the outside of the sleeve 818. The inner wall of the knob 810 and the threaded groove 809 are rotationally connected through external threads. The knobs 810 are all located on the side of the groove-shaped ring 805 away from the cover plate 804. A same shaft rod 811 is rotationally connected through a bearing inside the sleeve 818 and the collar 806 on the same side. A rotating piece 812 is connected to the side of the shaft rod 811 close to the cover plate 804 through a bolt. The rotating pieces 812 are all located inside the opening 808. And the outside of the sleeve 818 is slidably connected to the inner wall of the circular notch 819 on the same side; A rectangular frame 814 is connected to the inner wall of the steel column 1 close to the shaft rod 811 through a bolt. A locking plate 815 is slidably connected inside the rectangular frame 814. An annular groove 813 is formed on the outside of the shaft rod 811. The outside of the locking plate 815 and the inner wall of the annular groove 813 on the same side are both clamped. Two symmetric spring fours 816 are connected to the opposite sides of the inner wall of the locking plate 815 and the rectangular frame 814 through bolts. And an arc-shaped push rod 817 is connected to the annular groove 813 through a bolt. The arc-shaped push rods 817 are all located on the inner wall of the annular groove 813 away from the locking plate 815.

[0023] Specifically, when installing the outer vane plate 3 and the inner vane plate 4 on the steel column 1, open the cover plate 804, rotate the rotating piece 812 so that the triangle on the rotating piece 812 corresponds to the triangle on the collar 806, so that the bevel on the shaft rod 811 faces the locking plate 815. Loosen the knob 810, and the knob 810 and the collar 806 no longer clamp the grooved ring 805. Adjust the position of the sleeve 818 according to the position of the circular notch 819 on the steel column 1. After the adjustment is completed, tighten the knob 810 so that the collar 806 fits tightly against the rough surface groove 807. The knob 810 and the collar 806 clamp the grooved ring 805. Align the sleeve 818 with the position of the circular notch 819 and insert it. The bevel at one end of the shaft rod 811 pushes the locking plate 815 away. After the shaft rod 811 completely enters the circular notch 819, under the push of the spring four 816, the locking plate 815 will insert into the annular groove 813, thereby fixing the outer vane plate 3 and the inner vane plate 4 on the steel column 1. When it is necessary to remove the outer vane plate 3 and the inner vane plate 4 from the steel column 1, open the cover plate 804 and rotate the rotating piece 812. The rotating piece 812 drives the annular groove 813 to rotate, so that the arc-shaped push rod 817 in the annular groove 813 contacts one end of the locking plate 815 during rotation and gradually pushes the locking plate 815 out of the annular groove 813 as it rotates. Finally, remove the outer vane plate 3 and the inner vane plate 4.

[0024] In a specific application scenario, the quick disassembly and assembly module 8 is mainly applicable to the quick disassembly and assembly link during the quick disassembly and assembly process. That is, the quick disassembly and assembly module 8 can quickly and conveniently install the outer vane plate 3 and the inner vane plate 4 on the steel column 1 by using the annular groove 813 and the locking plate 815, and ensure the strength of the outer vane plate 3 and the inner vane plate 4 fixed on the steel column 1. The rotatable shaft rod 811 can quickly complete the locking of the locking plate 815 to the shaft rod 811 by using the push of the rotating arc-shaped push rod 817 when disassembling the outer vane plate 3 and the inner vane plate 4. That is, it greatly reduces the disassembly time of the workers and improves the disassembly and assembly efficiency of the workers for the outer vane plate 3 and the inner vane plate 4.

[0025] Working principle: Place the insulation board 2 between two steel columns 1. Align the movable rod 703 in the transverse pipe 701 with the fine holes on the steel column 1 and insert it. Under the pressure of the inner wall of the fine hole, the clamping block 718 retracts against the elastic force of the third spring 719, enabling the notch ring two 713 to smoothly pass through the notch ring one 711 and the notch ring two 713 in the fitting state. After passing through the notch ring one 711 and the notch ring two 713, the elastic force of the third spring 719 pops out the clamping block 718, so that the clamping block 718 is externally clamped with the notch ring two 713. Use a flat-tip screwdriver to rotate the rotating rod 707. The rotating rod 707 drives the first gear 709 to rotate, so that the second gear 712 meshing with the first gear 709 drives the notch ring one 711 to rotate 180 degrees. The notch ring two 713 gradually moves to a position symmetrical to the notch ring one 711 under the prying of the inclined surface of the notch ring one 711, so that the notch ring two 713 pushes the clamping block 718 to drive the movable rod 703 deeper into the steel column 1, enabling the movable rod 703 to be inserted into the mounting seat 710. One end of the movable rod 703 entering the mounting seat 710 pushes the clamping rod 722 away from the axis of the mounting seat 710 after contacting the clamping rod 722, enabling the movable rod 703 to continue to enter the mounting seat 710. After the notch ring one 711 rotates 180 degrees, the movable rod 703 stops moving. At this time, the annular groove 720 and the clamping rod 722 are on the same side plane. Under the torsion of the coil spring 726, the curved surface groove 725 on the rotating frame 724 rotates, so that the inner wall of the curved surface groove 725 pushes the short shaft 723 and drives the clamping rod 722 to move towards the axis of the mounting seat 710, and finally the clamping rod 722 is clamped with the annular groove 720, fixing the movable rod 703 on the steel column 1. When installing the outer leaf plate 3 and the inner leaf plate 4 on the steel column 1, open the cover plate 804 and rotate the rotating piece 812 so that the triangle on the rotating piece 812 corresponds to the triangle on the collar 806, so that the bevel on the shaft rod 811 faces the locking plate 815. Loosen the knob 810. The knob 810 and the collar 806 no longer clamp the groove-shaped ring 805. Adjust the position of the sleeve 818 according to the position of the circular groove opening 819 on the steel column 1. After the adjustment is completed, tighten the knob 810 so that the collar 806 fits tightly with the rough surface groove 807. The knob 810 and the collar 806 clamp the groove-shaped ring 805. Align the sleeve 818 with the position of the circular groove opening 819 and insert it, so that the inclined surface at one end of the shaft rod 811 pushes the locking plate 815 away. After the shaft rod 811 completely enters the circular groove opening 819, under the push of the fourth spring 816, the locking plate 815 will insert into the annular groove 813, thus fixing the outer leaf plate 3 and the inner leaf plate 4 on the steel column 1. When it is necessary to remove the outer leaf plate 3 and the inner leaf plate 4 from the steel column 1, open the cover plate 804 and rotate the rotating piece 812,The rotating piece 812 drives the annular groove 813 to rotate, so that the arc-shaped push rod 817 in the annular groove 813 contacts one end of the locking plate 815 during rotation and gradually ejects the locking plate 815 from the annular groove 813 as it rotates. Finally, the outer vane plate 3 and the inner vane plate 4 are removed.,
