When there is a strong wind, the insulation layer is often blown off, and product quality problems such as cracks and hollow walls are very likely to occur. In addition, the external wall insulation is directly exposed to the outside, exposed to the sun and rain. Due to long-term direct exposure to the harsh environment, the adhesive and fixing materials will age and loosen due to wind and rain, and the insulation wall panels will have the risk of falling from high altitude and cracking, affecting the actual service life of the external insulation; in addition, since the insulation layer is between the base layer and the outer surface layer, although reinforcement measures have been taken, the expansion coefficient and specific volume of the insulation material will still affect the stability between them, resulting in the possibility of peeling off of the "wall skin" part of the wall panels during the long-term use of the external insulation wall panels.

[0015] Preferably, the outer surface of the outer mortar layer is screwed with a bolt connector for installing the outer decoration, and the bolt connector includes a tubular screw tube, and the outer surface of one end of the screw tube is equidistantly and integrally connected with a threaded plate, and the outer surface of the screw tube and the outer surface of the threaded plate are both provided with threads with the same pitch, and the other end of the screw tube is sleeved with a sealing ring gasket for waterproofing, and the inner wall of the screw tube is provided with an inner screw cavity for screwing the mounting bolts, and the outer end of the inner wall of the screw tube is connected to four fan-shaped plastic waterproof flaps.

[0016] Correspondingly, the present invention also provides a construction method for manufacturing the above-mentioned elevated floor insulation structure, the steps of which are:

[0017] S1: First, clean the outer surface of the building wall, then install a horizontal keel on the outer surface of the building wall, then apply mortar on the back of the insulation board and stick the insulation board to the outer surface of the building wall, wherein the insulation board at the bottom has its bottom inserted into the inside of the keel;

[0018] S2: After installing two insulation boards horizontally, insert the reinforcement piece into the corner groove joint space at the top of the junction. During the process, the hook-shaped steel bars inside the two corner grooves are just inserted into the two straight interfaces at the bottom of the reinforcement board. Then, insert the bottom of a slot rod into the inside of the L-shaped connecting rod mouth. Then, lay and install two more insulation boards on top of the two insulation boards, and insert the hook-shaped steel bar at one corner of the bottom into the inside of the other two straight interfaces, and the slot rod just passes through the side grooves of the side walls of the two insulation boards.

[0019] S3: On the basis of step S2, the sleeve is rotated to make the condensation plate move horizontally and linearly on one side of the reinforcement plate, so that the corresponding hook-shaped steel bar is stuck in the inner part of the locking rib opening. Here, one reinforcement plate can be connected with the hook-shaped steel bars inside four insulation plates at the same time. Then, a bolt is inserted into the sleeve and drilled into the inner part of the building wall.

[0020] S4: Install the next reinforcement member according to the process of step S2, and the reinforcement member is located directly above the previous reinforcement member. At the same time, the top of the slot rod installed in step S2 is inserted into the direct rod opening at the bottom of the reinforcement plate. After the insertion is completed, the blocking frame just blocks the slot rod and makes the slot rod and the reinforcement plate in a fixed connection relationship. Finally, the reinforcement member is fixed according to the method in step S3;

[0021] S5: After the insulation board is fixed and installed, mortar is applied on the outer surface of the insulation board to form a second mortar layer, and then a mesh board is laid on the outer surface of the second mortar layer, and the mesh board is fixed by screwing the screw cap and the sleeve, and finally, mortar is applied on the outer surface of the mesh board to form a third mortar layer. After the mortar solidifies, a connecting mortar body will naturally form in the mesh holes of the mesh board;

[0022] S6: According to the needs of decoration, after the external insulation measures are installed and formed, according to the decoration design, the bolt connectors are driven into the corresponding wall panel positions. After driving them in, the bolt connectors used to install the external decoration are screwed into the inside of the screw tube, changing the traditional way of driving the bolt connectors into the wall.

[0023] From the above, the beneficial effects of the overhead floor insulation structure and the construction method thereof of the present invention are as follows:

[0024] 1. The ring steel bars and hook steel bars installed inside the insulation board are used to increase the structural strength of the insulation board itself and reduce the possibility of the insulation board being broken or damaged during use.

[0025] 2. The reinforcement structure provided can connect the hook-shaped steel bars inside the four insulation boards. Therefore, after the insulation boards are laid and installed, there is a connection force not only between the insulation boards and the building walls, but also between adjacent insulation boards. Therefore, when an insulation board and the wall skin tend to peel off, the force driving it to fall will be dispersed to the surrounding insulation boards, avoiding the possibility of a single insulation board peeling off and falling off. At the same time, the overall structure of the insulation board exterior wall is more stable, solving the hidden dangers of high-altitude falling and cracking of wall panels due to aging and loosening of adhesive materials due to harsh environment, thereby ensuring the actual service life of the external insulation.

[0026] 3. Under the action of a groove rod, a certain connection relationship can be established between the upper and lower reinforcement members, thereby indirectly increasing the range of the connection effect between the insulation boards, while avoiding the possibility of a large area of ​​external insulation wall panels peeling off together, further improving the structural stability of the external insulation wall.

[0027] 4. Apply mortar on the outer surface of the insulation board to form a second mortar layer, then lay the mesh plate on the outer surface of the second mortar layer, and fix the mesh plate by screwing the screw cap and the sleeve. Finally, apply mortar on the outer surface of the mesh plate to form a third mortar layer. After the mortar solidifies, a connecting mortar body will naturally form in the mesh holes of the mesh plate. Here, by connecting the mesh plate and the sleeve, the outer mortar layer can be connected to the building wall through the sleeve and bolts, so that the outer mortar layer can be more firmly arranged on the outer surface of the insulation board to avoid the risk of peeling of the "wall skin" of the external insulation wall panel. In addition, the formation of the connecting mortar body also forms an integrated connection structure between the second mortar layer and the third mortar layer, which cooperates with the mesh plate to improve the structural strength of the outer mortar layer.

[0028] 5. A bolt connection is provided, and according to the decoration design, the bolt connection used to install the external decoration can be screwed into the inside of the screw tube, which changes the traditional method of directly driving the bolt connection into the wall. After the external decoration and the bolt connection are removed, the screw tube is left in the nail hole, and the four fan-shaped plastic waterproof flaps at the end of the screw tube just block the opening of the screw tube, thereby preventing moisture from entering the screw tube and penetrating into the inside of the wall. In addition, the sealing ring gasket can also prevent moisture from penetrating into the wall from the gap, further preventing moisture from penetrating, and effectively preventing the insulation wall from mold.

[0043] According to the above structure, the outer surface of the building wall 1 is first cleaned, and then a horizontal keel 6 is installed on the outer surface of the building wall 1, and then mortar is applied to the back of the insulation board 2 to form a first mortar layer 3, and then the insulation board 2 is pasted and fixed to the outer surface of the building wall 1. In addition, the serrated groove 205 is provided to increase the contact area and contact friction between the mortar and the insulation board 2, wherein the insulation board 2 at the bottom has its bottom inserted into the interior of the keel 6.

[0044] Embodiment 1

[0045] like Figure 4 and Figure 5 As shown, corner grooves 201 are provided at the four corners of the insulation board 2, a ring steel bar 203 is fixedly provided inside the insulation board 2, and hook-shaped steel bars 204 are integrally connected to the four sides of the ring steel bar 203, the ends of the hook-shaped steel bars 204 extend to the inside of the corner grooves 201 respectively, and the ends of the hook-shaped steel bars 204 are set to be L-shaped hooks.

[0046] According to the above structure, the ring steel bars 203 and the hook steel bars 204 arranged inside the insulation board 2 are used to increase the overall structural strength of the insulation board 2 and reduce the possibility of breakage and damage of the insulation board 2 during use.

[0047] like Figure 3 , Figure 4 and Figure 6 As shown, a reinforcing member 7 is arranged in the integrated space of the four corner grooves 201 at the joint of four adjacent insulation boards 2. The reinforcing member 7 includes a reinforcing plate 701. The upper and lower ends of the reinforcing plate 701 are symmetrically provided with linear interfaces 702 with a middle horizontal line, and the hook-shaped end of the hook-shaped steel bar 204 is inserted into the corresponding linear interface 702. A condensation plate 708 is movably assembled on one side of the reinforcing plate 701. The four corners of the condensation plate 708 are symmetrically provided with locking rib openings 709 for clamping the ends of the hook-shaped steel bars 204 with a middle horizontal line. A vertical guide groove 711 is penetrated in the upper middle of the condensation plate 708. Guide pins 707 are fixedly arranged at two diagonal positions of the side surface of the reinforcing plate 701. Guide pin grooves 712 are provided at two diagonal positions of the condensation plate 708. The guide pins 707 are movably inserted into the guide pin grooves 712. A transverse guide groove 710 for the sleeve 9 to pass through is provided in the middle of the condensation plate 708.

[0048] like Figure 6 and Figure 7 As shown, a sleeve 9 is movably inserted into the joint of four adjacent insulation boards 2, and the end of the sleeve 9 is rotatably connected with the center of the reinforcement plate 701, and the sleeve 9 movably passes through the middle of the condensation plate 708. A guide rod 901 is fixedly provided on one side of the outer wall of the end of the sleeve 9, and the guide rod 901 is movably inserted into the interior of the vertical guide groove 711, and a bolt 902 is inserted through the interior of the sleeve 9, and the end of the bolt 902 is drilled into the interior of the building wall 1.

[0049] According to the above structure, after the two insulation boards 2 are installed horizontally, the reinforcement piece 7 is inserted into the splicing space of the corner groove 201 at the top of the junction. During the process, the hook-shaped steel bars 204 inside the two corner grooves 201 are just inserted into the two straight interfaces 702 located at the bottom of the reinforcement board 701. Subsequently, two more insulation boards 2 are laid and installed above the two insulation boards 2, and the hook-shaped steel bars 204 at one corner of their bottom are inserted into the other two straight interfaces 702; then, the sleeve 9 is rotated. Since the guide rod 901 is inserted into the vertical guide groove 711, the condensation plate 708 will move horizontally and linearly on one side of the reinforcement board 701, causing the corresponding hook-shaped steel bar 204 to be stuck in the locking rib mouth 709, and finally a reinforcement is achieved. The fixing plate 701 is connected to the hook-shaped steel bars 204 inside the four insulation boards 2 at the same time. This reinforcing member 7 structure can connect the hook-shaped steel bars 204 inside the four insulation boards 2. Therefore, after the insulation boards 2 are laid and installed, there is not only a connecting force between the insulation boards 2 and the building wall 1, but also a connecting force between adjacent insulation boards 2. Therefore, when an insulation board 2 and the wall skin tend to peel off, the force driving it to fall will be dispersed to the surrounding insulation boards 2, avoiding the possibility of a single insulation board 2 peeling off and falling off, and making the overall structure of the exterior wall of the insulation board 2 more stable, solving the hidden dangers of high-altitude falling and cracking of the wall panels due to aging and loosening of the adhesive material due to the harsh environment, thereby ensuring the actual service life of the external insulation.

[0050] like Figure 4 and Figure 6 As shown, an L-shaped connecting rod opening 703 is provided in the middle of the top of the reinforcing plate 701, a direct rod opening 704 is provided in the middle of the bottom of the reinforcing plate 701, a blocking frame 705 is rotatably mounted on the outer wall of the reinforcing plate 701 and located on one side of the direct rod opening 704, and a blocking block 706 is provided at the bottom of the outer wall of the reinforcing plate 701 for blocking the blocking frame 705. A slotted rod 8 is connected between two reinforcing plates 701 located in the same vertical direction, the bottom end of the slotted rod 8 is connected to the inside of the L-shaped connecting rod opening 703 of the reinforcing plate 701 located at the bottom, and the top end of the slotted rod 8 is connected to the inside of the direct rod opening 704 of the reinforcing plate 701 located at the top.

[0051] like Figure 1 and Figure 4 As shown, the outer walls on both sides of the insulation board 2 are provided with side grooves 202 for the groove rods 8 to pass through, and the outer side of the keel 6 is equidistantly provided with notches 601 for providing installation space for the reinforcement member 7.

[0052] When the first reinforcement piece 7 is installed, the bottom of a slot rod 8 is inserted into the L-shaped connecting rod opening 703. When the next reinforcement piece 7 is installed above it, the top of the slot rod 8 installed in the previous step is inserted into the direct rod opening 704 of the next reinforcement plate 701. During the plugging process, the slot rod 8 will first push the retaining frame 705 to rotate. After the slot rod 8 is fully inserted, the retaining frame 705 will be separated from the top of the slot rod 8 and rotated to reset. Under the obstruction of the stop block 706, the horizontal retaining frame 705 just blocks the slot rod 8 and makes the slot rod 8 and the reinforcement plate 701 in a fixed connection relationship. At this time, under the action of a slot rod 8, a certain connection relationship can be established between the upper and lower reinforcement pieces 7, thereby indirectly increasing the range of the connection effect between the insulation board 2, while avoiding the possibility of a large area of ​​the external insulation wall panel area peeling off together, further improving the structural stability of the external insulation wall.

[0053] The working principle of the present invention is as follows: after two insulation boards 2 are horizontally installed, a reinforcing member 7 is inserted into the joint space of the corner groove 201 at the top of the junction. During the process, the hook-shaped steel bars 204 inside the two corner grooves 201 are just inserted into the two straight interfaces 702 at the bottom of the reinforcing plate 701. Then, the bottom of a groove rod 8 is inserted into the L-shaped connecting rod opening 703. Subsequently, two more insulation boards 2 are laid and installed above the two insulation boards 2, and the corners of the bottom of the two insulation boards 2 are inserted into the two straight interfaces 702 at the bottom of the reinforcing plate 701. The hook-shaped steel bar 204 is inserted into the inside of the other two linear interfaces 702, and the groove rod 8 just passes through the side grooves 202 of the side walls of the two insulation boards 2; then, the sleeve 9 is rotated, and since the guide rod 901 is inserted into the vertical guide groove 711, the condensation plate 708 will move horizontally and linearly on one side of the reinforcement plate 701, causing the corresponding hook-shaped steel bar 204 to be stuck in the inside of the locking rib mouth 709, and finally one reinforcement plate 701 is connected to the hook-shaped steel bars 204 inside the four insulation boards 2 at the same time.

[0054] Next, a bolt 902 is inserted into the sleeve 9 and drilled into the interior of the building wall 1, thereby creating a connecting force between the reinforcement 7 and the building wall 1; then the next reinforcement 7 is installed, and the reinforcement 7 is located directly above the previous reinforcement 7. At this time, the top of the slotted rod 8 connected in the previous step will be inserted into the direct rod opening 704 of the next reinforcement plate 701. During the plug-in process, the slotted rod 8 will first push the retaining frame 705 to rotate. After the slotted rod 8 is fully inserted, the retaining frame 705 will be separated from the top of the slotted rod 8 and rotated to reset. Under the obstruction of the stopper 706, the horizontal retaining frame 705 just blocks the slotted rod 8 and makes the slotted rod 8 and the reinforcement plate 701 in a fixed connection relationship. At this time, under the action of one slotted rod 8, a certain connection effect can also be created between the upper and lower reinforcements 7.

[0057] like Figure 7 As shown, one end of the sleeve 9 away from the building wall 1 is movably screwed with a screw cover 903 for fixing the mesh plate 5, and the inner wall of the sleeve 9 away from the building wall 1 is provided with a thread.

[0058] According to the above structure, mortar is applied on the outer surface of the insulation board 2 to form a second mortar layer 401, and then the mesh plate 5 is laid on the outer surface of the second mortar layer 401, and the mesh plate 5 is fixed by screwing the screw cap 903 and the sleeve 9. Finally, mortar is applied on the outer surface of the mesh plate 5 to form a third mortar layer 402. After the mortar solidifies, a connecting mortar body 403 will naturally be formed in the mesh holes of the mesh plate 5. Here, by connecting the mesh plate 5 with the sleeve 9, the outer mortar layer 4 can be connected to the building wall 1 through the sleeve 9 and the bolts 902, so that the outer mortar layer 4 can be more firmly arranged on the outer surface of the insulation board 2, thereby avoiding the hidden danger of peeling of the "wall skin" of the external insulation wall panel.

[0059] The working principle of the present invention is as follows: after the insulation board 2 is fixed and installed, mortar is applied on the outer surface of the insulation board 2 to form a second mortar layer 401, and then the mesh plate 5 is laid on the outer surface of the second mortar layer 401, and the mesh plate 5 is fixed by screwing the screw cover 903 and the sleeve 9, and finally, mortar is applied on the outer surface of the mesh plate 5 to form a third mortar layer 402. After the mortar solidifies, a connecting mortar body 403 will naturally form in the mesh holes of the mesh plate 5.

[0062] According to the above structure, in the process of driving the bolt connection 10 into the surface of the external insulation wall panel, the setting of the threaded plate 1002 can apply a squeezing force to the inside of the wall after the screw tube 1001 is driven into the wall, thereby ensuring the stable and long-term use of the screw tube 1001. According to the decoration design, the bolt connection used to install the external decoration is screwed into the inside of the screw tube 1001. After the external decoration and the bolt connection are removed, the screw tube 1001 can be left in the nail hole, and the four fan-shaped plastic waterproof flaps 1004 at the end of the screw tube 1001 just block the opening of the screw tube 1001, thereby preventing moisture from entering the screw tube 1001 and penetrating into the wall.

[0063] The working principle of the present invention is: according to the decoration needs, after the external insulation measures are installed and formed, according to the decoration design, the bolt connector 10 is driven into the corresponding wall panel position. After being driven in, the bolt connector used to install the external decoration is screwed into the inside of the screw tube 1001, changing the traditional method of directly driving the bolt connector into the wall.

[0064] Accordingly, the construction method of the overhead floor insulation structure of the present invention comprises the following specific steps:
