Description

Technical Field

[0001] The present application belongs to the technical field of exterior wall insulation, and specifically relates to an exterior wall insulation structure. Background Art

[0002] With the promotion and application of energy-saving buildings, insulation boards are usually installed on the exterior walls of buildings today to improve the insulation performance of the buildings, reduce energy consumption and improve the living comfort of residents. At the same time, in order to increase the aesthetics of the exterior walls of the buildings, it is necessary to apply anti-cracking mortar on the outside of the insulation boards and apply wall paint on the anti-cracking mortar to improve the aesthetics of the exterior walls of the buildings.

[0003] At present, when installing the insulation board, it is necessary to first apply glue on the exterior wall, then install the insulation board to the exterior wall, then drill holes in the insulation board and the exterior wall, and use insulation nails to fix the insulation board, that is, one end of the insulation nail is passed through the insulation board and into the wall, so that the nail head of the insulation nail contacts the insulation board to achieve the fixation of the insulation board. However, when drilling holes in the insulation board, the insulation board will vibrate, which will affect the bonding effect between the insulation board and the exterior wall, and the dust generated by drilling holes in the exterior wall will enter between the insulation board and the exterior wall, thereby further affecting the bonding effect between the insulation board and the exterior wall, and then affecting the fixing effect of the insulation board. At the same time, during the installation of the insulation nails, if the pre-tightening force applied to the insulation nails is large, grooves will be generated in the insulation board. If the pre-tightening force applied to the insulation nails is small, it will affect the fixing effect of the insulation board and the nail head of the insulation nail will protrude from the outer side of the insulation nail. Regardless of whether the pre-tightening force applied to the insulation nails is large or small, the thickness of the anti-cracking mortar applied to the insulation board will be uneven. After a long time, the anti-cracking mortar will cause cracks, thereby affecting the service life of the anti-cracking mortar. Utility Model Content

[0004] The present application provides an exterior wall insulation structure, which increases the fixing effect of the insulation board and increases the service life of the anti-cracking mortar.

[0005] The technical solution adopted in this application is:

[0006] An exterior wall insulation structure comprises an insulation board and a fixing piece arranged at the end of the insulation board, the fixing piece comprises a fixing strip and an extrusion strip, and the fixing strip has a fixing section and a connecting section, the fixing section is fixedly connected to the exterior wall, the extrusion strip abuts against the outer side surface of the insulation board and is snap-fitted with the connecting section, and the insulation board is provided with avoidance notches corresponding to the fixing section and the extrusion strip, so that the fixing section is flush with the inner side surface of the insulation board and the extrusion strip is flush with the outer side surface of the insulation board.

[0007] By adopting the above technical scheme, when installing the insulation board, the fixed section is first fixedly connected to the exterior wall using an expansion tube, and then glue is applied to the exterior wall, and then the insulation board is installed so that the avoidance notch on the inner side of the insulation board is opposite to the fixed section, that is, the fixed section is located in the avoidance notch on the inner side of the insulation board, and the insulation board is bonded to the exterior wall by glue, and then the extrusion strip is installed so that the extrusion strip and the connecting section are snap-fitted together, and at the same time, the extrusion strip is located in the avoidance notch on the outer side of the insulation board and contacts the insulation board to apply a force toward the exterior wall to the insulation board. At this time, the outer side surface of the insulation board is flush with the extrusion strip to complete the installation of the insulation board. In this process, the need to punch holes in the insulation board after bonding the insulation board to the exterior wall is avoided, thereby increasing the bonding effect of the insulation board and the exterior wall, and at the same time, the situation in which dust enters between the insulation board and the exterior wall due to drilling holes in the exterior wall and affects the bonding effect of glue on the insulation board is avoided, so as to further improve the fixing effect of the insulation board.

[0008] In addition, the setting of the extrusion strip increases the fixing area of ​​the insulation board to further increase the stability of the insulation board. Moreover, the setting of the avoidance gap makes the extrusion strip flush with the outer side of the insulation board, so that the thickness of the anti-cracking mortar applied to the insulation board remains consistent, thereby avoiding the situation where the anti-cracking mortar is easy to crack, thereby increasing the service life of the anti-cracking mortar.

[0009] Optionally, the extrusion strip has an internally hollow clamping column, the clamping column is provided with a partition groove along its axial direction, and a clamping portion is provided at one end of the clamping column away from the extrusion strip, the connecting section has a connecting hole and a clamping hole, the aperture of the clamping hole is larger than the aperture of the connecting hole, when the extrusion strip is clamped together with the connecting section, the clamping column is passed through the connecting hole, and the clamping portion is clamped together with the end wall of the clamping hole.

[0010] By adopting the above technical solution, when installing the extrusion strip, first align the extrusion strip with the connecting section, then apply pressing force to the extrusion strip in the direction of the connecting section so that the clamping part contacts the hole opening of the connecting hole, and then continue to press the extrusion strip so that the clamping part applies pressure to the clamping column, the clamping column deforms, and the distance between the partition groove and the groove wall gradually decreases, so that the clamping part passes over the connecting hole and enters the clamping hole, and then the clamping column resumes deformation, and finally the clamping part is clamped and matched with the end wall of the clamping hole to complete the installation of the extrusion strip. In this process, it is only necessary to press the extrusion strip, thereby reducing the difficulty of installing the extrusion strip and improving the construction efficiency of the insulation board.

[0011] Optionally, the clamping portion is an annular structure extending along the circumference of the clamping column, and the diameter of the clamping portion gradually increases in a direction approaching the extrusion strip.

[0012] By adopting the above technical solution, since the clamping part is an annular structure extending along the circumference of the clamping column, the clamping area between the clamping part and the end wall of the clamping hole is increased, thereby increasing the clamping stability of the extrusion strip and the connecting section. At the same time, the diameter of the clamping part gradually increases in the direction close to the extrusion strip, so that when the extrusion strip is installed, the clamping part can guide the deformation direction of the clamping column to reduce the force required for installing the extrusion strip, thereby reducing the labor workload of the staff when installing the extrusion strip and alleviating the problem of the staff feeling easily fatigued.

[0013] Optionally, the diameter of the clamping portion at one end away from the extrusion strip is equal to the hole diameter of the connecting hole.

[0014] By adopting the above technical solution, the diameter of the clamping part away from the end of the extrusion strip is set to be equal to the aperture of the connecting hole, which can further reduce the force required for the staff to install the extrusion strip, thereby further reducing the workload of the staff and further alleviating the problem of the staff feeling easily fatigued.

[0015] Optionally, a locking rod and an elastic member acting on the locking rod are slidably connected in the locking hole, so that when the locking portion extends into the locking hole, the locking rod and the locking column elastically give way to each other, and when the locking portion is engaged with the end wall of the locking hole, the locking rod extends into the locking column under the action of the elastic member.

[0016] By adopting the above technical scheme, during the installation of the extrusion strip, the clamping column is deformed so that the clamping part enters the connecting hole. After the clamping part enters the connecting hole, the end of the clamping column contacts the end of the locking rod, and continues to apply pressing force to the extrusion strip to make the clamping column and the clamping part continue to move, so that the clamping column applies downward pressure on the locking rod, and the locking rod applies pressure on the elastic member, and the elastic member is elastically deformed so that the locking rod and the clamping column form a mutual avoidance. When the clamping part is clamped and matched with the end wall of the clamping hole, the elastic member restores the deformation and pushes the locking rod, and then the locking rod extends into the clamping column to avoid the situation where the clamping part is separated from the end wall of the clamping hole due to the deformation of the clamping column, thereby increasing the clamping stability of the extrusion strip and the connecting section, so as to further increase the fixing effect of the insulation board.

[0017] Optionally, the elastic member is a spring sleeved on the outside of the locking rod, a blocking portion is provided on the outside of the locking rod, and two ends of the spring act on the blocking portion and the end wall of the clamping hole respectively.

[0018] By adopting the above technical solution, after the clamping part enters the connecting hole, the end of the clamping column contacts the end of the locking rod and continues to apply pressing force to the extrusion strip. The clamping column applies pressure to the locking rod, and the locking rod drives the blocking part to move. The blocking part applies pressure to the spring, which then causes the spring to deform. The locking rod and the clamping column form an elastic avoidance. After the clamping part is clamped with the end wall of the clamping hole, the spring restores its deformation and pushes the blocking part. The blocking part drives the locking rod to move so that the locking rod extends into the clamping column. The elastic member is set as a spring sleeved on the outside of the locking rod, which increases the elastic movement effect of the locking rod, thereby reducing the difficulty of installing the extrusion strip and ensuring the clamping stability of the extrusion strip and the connecting section.

[0019] Optionally, the connecting section is provided with a guide hole connected to the engaging hole, and one end of the locking rod extends into the guide hole.

[0020] By adopting the above technical solution, when the locking rod moves under the action of the clamping column and the elastic member, the locking rod and the guide hole slide relative to each other, and then the hole wall of the guide hole guides the movement of the locking rod to increase the stability of the locking rod movement, while ensuring that the locking rod can accurately extend into the clamping column to ensure the clamping stability of the extrusion strip and the connecting section.

[0021] Optionally, a guide surface is provided along the circumference of one end of the locking rod close to the extrusion strip.

[0022] By adopting the above technical solution, since a guide surface is provided along the circumference of one end of the locking rod close to the extrusion strip, the diameter of the locking rod close to the extrusion strip is reduced, so that the locking rod can be more easily extended into the clamping column, thereby further ensuring the connection stability between the extrusion strip and the connecting section.

[0023] Optionally, the connecting section is provided with a positioning groove, and the extrusion strip is provided with a positioning rib extending into the positioning groove.

[0024] By adopting the above technical solution, when installing the extrusion strip, the positioning rib is first aligned with the positioning groove, and then a pressing force is applied to the extrusion strip in the direction of the connecting section so that the positioning rib enters and extends into the positioning groove, thereby aligning the clamping column with the clamping hole, thereby reducing the difficulty of assembling the extrusion strip and thereby improving the installation efficiency of the extrusion strip.

[0025] Optionally, two opposite groove walls of the positioning groove gradually decrease in a direction approaching the fixing section.

[0026] By adopting the above-mentioned technical scheme, since the two opposite groove walls of the positioning groove gradually decrease in the direction approaching the fixed section, during the installation of the extrusion strip, the extrusion strip can be automatically adjusted under the action of the groove walls of the positioning groove, so as to reduce the difficulty of positioning the extrusion strip, thereby further reducing the difficulty of installing the extrusion strip, and further improving the installation efficiency of the extrusion strip.

[0027] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

The exterior wall insulation structure in the present application includes an insulation board and a fixing member arranged at the end of the insulation board, the fixing member includes a fixing strip and an extrusion strip, and the fixing strip has a fixing section and a connecting section, the fixing section is fixedly connected to the exterior wall, the extrusion strip abuts against the exterior side of the insulation board and is engaged with the connecting section, and the insulation board is provided with an avoidance notch corresponding to the fixing section and the extrusion strip, so that the fixing section is flush with the interior side of the insulation board and the extrusion strip is flush with the exterior side of the insulation board. In the process of installing the exterior wall insulation structure in the present application, it is avoided that the insulation board needs to be punched after being bonded to the exterior wall, thereby increasing the bonding effect between the insulation board and the exterior wall, and at the same time, it is avoided that dust enters between the insulation board and the exterior wall due to drilling holes in the exterior wall, which affects the bonding effect of the glue on the insulation board, so as to further improve the fixing effect of the insulation board. By setting the extrusion strip, the fixing area of ​​the insulation board is increased, so as to further increase the stability of the insulation board. By setting the avoidance gap, the extrusion strip is flush with the outer side surface of the insulation board, so that the thickness of the anti-cracking mortar applied to the insulation board is kept consistent, thereby avoiding the anti-cracking mortar from cracking easily, thereby increasing the service life of the anti-cracking mortar.

[0030] 3. The clamping portion in the present application is an annular structure extending along the circumference of the clamping column, thereby increasing the clamping area between the clamping portion and the end wall of the clamping hole, thereby increasing the clamping stability of the extrusion strip and the connecting section.

[0045] Reference Figures 1 to 6 , discloses an exterior wall insulation structure, which includes an insulation board 1 and a fixing member 2 arranged at the end of the insulation board 1, the fixing member 2 includes a fixing strip 21 and an extrusion strip 22, and the fixing strip 21 has a fixing section 211 and a connecting section 212, the fixing section 211 is fixedly connected to the exterior wall, the extrusion strip 22 abuts against the outer side surface of the insulation board 1 and is snap-fitted with the connecting section 212, and the insulation board 1 is provided with an avoidance notch 11 corresponding to the fixing section 211 and the extrusion strip 22, so that the fixing section 211 is flush with the inner side surface of the insulation board 1 and the extrusion strip 22 is flush with the outer side surface of the insulation board 1.

[0046] When installing the insulation board 1, first use the expansion tube to fix the fixing strip 21 to the outer wall, that is, fix the fixing section 211 to the outer wall, and then apply glue to the outer wall, and then install the insulation board 1 so that the avoidance notch 11 on the inner side of the insulation board 1 is opposite to the fixing section 211, that is, the fixing section 211 is located in the avoidance notch 11 on the inner side of the insulation board 1, and the insulation board 1 is glued to the outer wall, and then install the extrusion strip 22 so that the extrusion strip 22 and the connecting section 212 are snap-fitted together, and the extrusion strip 22 is located at The avoidance notch 11 on the outside of the insulation board 1 is in contact with the insulation board 1 to apply a force to the insulation board 1 toward the outer wall. At this time, the outer side surface of the insulation board 1 is flush with the extrusion strip 22 to complete the installation of the insulation board 1. In this process, the need to punch holes in the insulation board 1 after bonding the insulation board 1 to the outer wall is avoided, thereby increasing the bonding effect of the insulation board 1 and the outer wall. At the same time, it is avoided that dust enters between the insulation board 1 and the outer wall due to drilling holes in the outer wall, affecting the bonding effect of the glue on the insulation board 1, so as to further improve the fixing effect of the insulation board 1.

[0047] By setting the extrusion strip 22, the fixing area of ​​the insulation board 1 is increased to further increase the stability of the insulation board 1. In addition, by setting the avoidance notch 11, the extrusion strip 22 is flush with the outer side of the insulation board 1, so that the thickness of the anti-cracking mortar applied to the insulation board 1 is kept consistent, so as to avoid the anti-cracking mortar from easily cracking, thereby increasing the service life of the anti-cracking mortar.

[0048] It should be noted that when installing the insulation board 1 , fixing members 2 need to be installed at both ends of the insulation board 1 to increase the stability of the insulation board 1 .

[0049] The present application does not specifically limit the shape of the fixing member 2. Preferably, refer to Figures 1 to 4 , the connecting section 212 is arranged perpendicularly to the fixing section 211, and the connecting section 212 is located in the middle position in the width direction of the fixing section 211, so that the fixing section 211, the connecting section 212 and the extrusion strip 22 together form an "I" shape, so that two adjacent insulation boards 1 can share a fixing member 2, so as to reduce the construction cost of the exterior wall insulation structure. In other embodiments, the connecting section 212 is arranged at the end of the fixing section 211 in the width direction, so that the fixing section 211, the connecting section 212 and the extrusion strip 22 together form a "C" shape.

[0050] The present application does not specifically limit the snap-fitting manner of the extrusion strip 22 and the connecting section 212, and it may adopt any one of the following embodiments:

[0051] Implementation method 1: In this implementation method, refer to Figure 4 and Figure 5The extrusion strip 22 has an internally hollow clamping column 221, and the clamping column 221 is provided with a partition groove 223 along its axial direction, and a clamping portion 222 is provided at one end of the clamping column 221 away from the extrusion strip 22. The connecting section 212 has a connecting hole 213 and a clamping hole 214. The aperture of the clamping hole 214 is larger than the aperture of the connecting hole 213, and the clamping hole 214 is located at one end of the connecting hole 213 close to the fixed section 211. When the extrusion strip 22 is clamped with the connecting section 212, the clamping column 221 is penetrated into the connecting hole 213, and the clamping portion 222 is clamped with the end wall of the clamping hole 214.

[0052] It can be understood that the length direction of the partition groove 223 is arranged parallel to the axial direction of the clamping column 221 , and a plurality of partition grooves 223 are arranged along the circumference of the clamping column 221 to increase the deformation capacity of the clamping column 221 .

[0053] When installing the extrusion strip 22, first align the extrusion strip 22 with the connecting section 212, and then apply pressing force to the extrusion strip 22 in the direction of the connecting section 212, so that the clamping portion 222 contacts the orifice of the connecting hole 213, and then continue to press the extrusion strip 22, so that the clamping portion 222 applies pressure to the clamping column 221, the clamping column 221 is deformed, and the distance between the partition groove 223 and the groove wall is gradually reduced, so that the clamping portion 222 passes over the connecting hole 213 and enters the clamping hole 214, and then the clamping column 221 restores the deformation, and finally the clamping portion 222 is clamped and matched with the end wall of the clamping hole 214 to complete the installation of the extrusion strip 22. In this process, you only need to press the extrusion strip 22, thereby reducing the difficulty of installing the extrusion strip 22 and improving the construction efficiency of the insulation board 1.

[0054] The present application does not specifically limit the structure of the clamping portion 222. Preferably, refer to Figure 5 The clamping portion 222 is an annular structure extending along the circumference of the clamping column 221, thereby increasing the clamping area between the clamping portion 222 and the end wall of the clamping hole 214, thereby increasing the clamping stability of the extrusion strip 22 and the connecting section 212; the diameter of the clamping portion 222 gradually increases in the direction approaching the extrusion strip 22, thereby enabling the clamping portion 222 to guide the deformation direction of the clamping column 221 when installing the extrusion strip 22, so as to reduce the force required for installing the extrusion strip 22, thereby reducing the labor workload of the staff when installing the extrusion strip 22, and alleviating the problem of the staff feeling easily fatigued.

[0055] In other embodiments, the clamping portion 222 may also be a block structure arranged at intervals along the circumference of the clamping column 221 .

[0056] Furthermore, the diameter of the clamping portion 222 away from one end of the extrusion strip 22 is equal to the aperture of the connecting hole 213, which can further reduce the force required for the staff to install the extrusion strip 22, thereby further reducing the workload of the staff and further alleviating the problem of the staff feeling easily fatigued.

[0057] In a preferred embodiment, referring to Figure 4 and Figure 6 A locking rod 216 and an elastic member 217 acting on the locking rod 216 are slidably connected in the snap-in hole 214, so that when the snap-in portion 222 extends into the snap-in hole 214, the locking rod 216 and the snap-in column 221 elastically give way to each other, and when the snap-in portion 222 is snap-fitted with the end wall of the snap-in hole 214, the locking rod 216 extends into the snap-in column 221 under the action of the elastic member 217.

[0058] Specifically, during the installation of the extrusion strip 22, the clamping column 221 is deformed under the extrusion of the clamping portion 222, so that the clamping portion 222 enters the connecting hole 213. After the clamping portion 222 enters the connecting hole 213, the end of the clamping column 221 contacts the end of the locking rod 216, and the pressing force is continuously applied to the extrusion strip 22, so that the clamping column 221 and the clamping portion 222 continue to move, so that the clamping column 221 applies downward pressure to the locking rod 216, and the locking rod 216 applies pressure to the elastic member 217, and the elastic member 217 is pressed downward. The elastic member 217 undergoes elastic deformation so that the locking rod 216 and the clamping column 221 avoid each other. When the clamping portion 222 is clamped together with the end wall of the clamping hole 214, the elastic member 217 recovers its deformation and pushes the locking rod 216, thereby causing the locking rod 216 to extend into the clamping column 221 to avoid the clamping column 221 from deforming and causing the clamping portion 222 to separate from the end wall of the clamping hole 214, thereby increasing the clamping stability of the extrusion strip 22 and the connecting section 212, so as to further increase the fixing effect of the insulation board 1.

[0059] Better, refer to Figure 4 and Figure 6 After the locking rod 216 extends into the clamping column 221 under the action of the elastic member 217, the locking rod 216 has a portion overlapping with the connecting hole 213 to increase the clamping stability between the clamping portion 222 and the end wall of the clamping hole 214. At the same time, when the extrusion strip 22 is not installed to the connecting section 212, the blocking portion 225 abuts against the end wall of the clamping hole 214 to limit the locking rod 216 to prevent the locking rod 216 from being separated from the connecting section 212, thereby increasing the stability of the locking rod 216.

[0060] The present application does not specifically limit the structure of the elastic member 217. Preferably, refer to Figure 4 and Figure 6The elastic member 217 is a spring sleeved on the outside of the locking rod 216. A blocking portion 225 is provided on the outside of the locking rod 216. The two ends of the spring act on the blocking portion 225 and the end wall of the snap-in hole 214 respectively. That is to say, one end of the spring abuts against the end of the blocking portion 225 away from the extrusion strip 22, and the other end of the spring abuts against the end wall of the snap-in hole 214 close to the fixing section 211.

[0061] The locking rod 216 is pressed against the locking post 221 to release the locking force.

[0062] The present application does not specifically limit the structure of the blocking portion 225. Preferably, refer to Figure 4 and Figure 6 The blocking portion 225 is an annular structure extending along the circumference of the locking rod 216 to increase the contact area with the spring, thereby increasing the elastic effect of the spring on the locking rod 216. In other embodiments, the blocking portion 225 can also be a block structure arranged at intervals along the circumference of the locking rod 216.

[0063] In other embodiments, the elastic member 217 may also be an elastic sheet, an elastic column, or other elastically deformable structures disposed at one end of the locking rod 216 close to the fixing section 211 .

[0064] Further, refer to Figure 4 and Figure 6 The connecting section 212 is provided with a guide hole 218 connected to the clamping hole 214, and one end of the locking rod 216 extends into the guide hole 218, so that when the locking rod 216 moves under the action of the clamping column 221 and the elastic member 217, the locking rod 216 and the guide hole 218 slide relative to each other, and then the hole wall of the guide hole 218 guides the movement of the locking rod 216 to increase the stability of the movement of the locking rod 216, and at the same time ensure that the locking rod 216 can accurately extend into the clamping column 221 to ensure the clamping stability of the extrusion strip 22 and the connecting section 212.

[0065] Better, refer to Figure 4and Figure 6 A guide surface 219 is provided along the circumference of one end of the locking rod 216 close to the extrusion strip 22, thereby reducing the diameter of the locking rod 216 close to the extrusion strip 22, so that the locking rod 216 can be more easily inserted into the clamping column 221, so as to further ensure the connection stability between the extrusion strip 22 and the connecting section 212.
