Description

Technical Field

[0001] The utility model belongs to the technical field of building exterior walls, and particularly relates to a heat preservation structure for an assembled building exterior wall. Background Technique

[0002] With the improvement of people's requirements for the comfort of living environment and the increasingly severe energy crisis, building energy conservation has become an important development direction in the building industry. The building envelope structure is one of the key factors affecting building energy consumption, and as an important part of the envelope structure, the heat preservation performance of the exterior wall is directly related to the energy-saving effect of the building.

[0003] The existing assembled exterior wall enables multiple wall panels to be quickly connected in a mutually intersecting manner, and a plurality of alloy rods are fixed between the wall panels to limit the position of the wall body, so as to ensure that the installation position of the wall body will not shift. A waterproof layer is arranged between the heat preservation layer of the wall panel and the exterior wall, so as to prevent the heat preservation layer from losing its heat preservation ability due to water vapor erosion.

[0004] After the above equipment is completed, due to the different regions where the wall panels need to be used and the different external temperatures and humidities they feel, the heat preservation materials in the wall panels may expand accidentally, resulting in problems such as deformation of the wall panels. Therefore, we propose a heat preservation structure for an assembled building exterior wall. Content of the Utility Model

[0005] The purpose of the utility model is to provide a heat preservation structure for an assembled building exterior wall. Through the heat preservation mechanism and the installation mechanism, the problems that due to the different regions where the wall panels need to be used and the different external temperatures and humidities they feel, the heat preservation materials in the wall panels may expand accidentally, resulting in problems such as deformation of the wall panels are solved.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a heat preservation structure for an assembled building exterior wall, including a housing. A connecting block is fixedly connected to the outer wall of the housing, and a limiting groove is opened on the inner wall of the housing;

[0008] A heat preservation mechanism is arranged on the inner wall of the housing. The heat preservation mechanism includes a plurality of exterior walls. The outer walls of the plurality of exterior walls are fixedly connected to the inner wall of the housing. A bottom plate is fixedly connected to the bottom outer wall of the exterior wall. A plurality of waterproof layers are fixedly connected to the top outer wall of the bottom plate. A partition plate is fixedly connected to the outer wall of the plurality of waterproof layers away from the exterior wall. A heat preservation plate is fixedly connected to the top outer wall of the bottom plate. A plurality of slopes are fixedly connected to the outer wall of the heat preservation plate. A plurality of water storage grooves are opened on the inner wall of the slopes. A drainage groove is opened on the inner wall of the bottom plate. A partition net is fixedly connected to the outer wall of the bottom plate. An installation mechanism is arranged on the outer wall of the housing.

[0009] Furthermore, the installation mechanism includes a limit block, the outer wall of the limit block is fixedly connected to the outer wall of the housing, a positioning hole is provided in the inner wall of the limit block, and a plurality of threaded sleeves are fixedly connected to the outer wall of the housing on the side away from the limit block.

[0010] Furthermore, a hollow fixed tube is threadedly connected to the inner wall of the threaded sleeve, a positioning shell is fixedly connected to the bottom outer wall of the hollow fixed tube, a plurality of limit holes are provided in the inner wall of the positioning shell, and a plurality of I-shaped chutes are provided in the inner wall of the hollow fixed tube.

[0011] Furthermore, a telescopic rod is slidably connected to the inner wall of the hollow fixed tube, a plurality of positioning blocks are fixedly connected to the outer wall of the telescopic rod, the outer wall of the positioning block is slidably connected to the inner wall of the I-shaped chute, and a push rod is fixedly connected to the top outer wall of the telescopic rod.

[0012] Furthermore, a compression spring is fixedly connected to the inner wall of the telescopic rod close to the push rod, and a spring is fixedly connected to the bottom of the inner wall of the hollow fixed tube.

[0013] Furthermore, one end of the spring away from the positioning shell is fixedly connected to a connecting plate, and a plurality of positioning seats are fixedly connected to the outer wall of the connecting plate.

[0014] Furthermore, a hollow rod is rotatably connected to the inner wall of the positioning seat, and a positioning rod is slidably connected to the inner wall of the hollow rod.

[0015] Furthermore, the outer wall of the positioning rod is fixedly connected to the outer wall of the positioning shell, and the outer wall of the hollow rod is clamped with the inner wall of the positioning hole.

[0016] The utility model has the following beneficial effects:

[0017] 1. By setting a slope and a drainage groove, the utility model uses a partition board to separate the heat preservation board from the exterior wall, and leaves a gap between the heat preservation board and the partition board. At the same time, when the indoor and outdoor temperatures are inconsistent, the water droplets generated by the heat and cold alternation will condense on the surface of the heat preservation board. Through the slopes on both sides of the heat preservation board, the water droplets can flow, and the water droplets are gathered together through a plurality of water storage grooves. At the same time, the drainage groove is communicated with the water storage groove, so as to isolate a certain space between the heat preservation board and the exterior wall through the partition board, and discharge the liquid through the drainage groove, preventing problems such as accidental expansion of the heat preservation material in the wall panel and deformation of the wall panel due to different external temperatures and humidities felt due to different locations where the wall panel needs to be used.

[0018] 2. In the present utility model, by providing a telescopic rod and a hollow rod, during the movement of the telescopic rod, the front end of the telescopic rod will push the connecting plate, and the connecting plate will squeeze the spring at the bottom. The elastic force of the spring restricts the movement range of the connecting plate. The movement of the connecting plate drives the movement of multiple positioning seats, and the positioning seats drive the movement of the hollow rod. Since the hollow rod is restricted by the positioning rod, the hollow rod will rotate around the positioning rod, and at the same time, the positioning rod slides along the chute inside the hollow rod, so that the front end of the hollow rod is inserted into the positioning hole, and the device is stuck in the limiting block, achieving the effect that the movement of the telescopic rod pushes the connecting plate and drives the positioning seat to move, thereby pushing the hollow rod to insert it into the limiting block, preventing the problem that the wall panels connected by splicing are prone to wear during use, and the two wall panels are no longer in contact, resulting in the wall panels being prone to violent shaking due to external forces.

[0019] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Please refer to Figures 1-5 As shown, the present invention is a thermal insulation structure for the outer wall of a prefabricated building, including an outer shell 1. A connecting block 102 is fixedly connected to the outer wall of the outer shell 1. A limit groove 101 is opened on the inner wall of the outer shell 1. By opening the limit groove 101 on the right side of the outer shell 1, the remaining devices can be inserted into the limit groove 101 by using the connecting block 102, so as to achieve rapid connection;

[0030] The inner wall of the outer shell 1 is provided with a heat preservation mechanism 2. The heat preservation mechanism 2 includes a number of outer walls 201. The outer walls of the number of outer walls 201 are fixedly connected to the inner wall of the outer shell 1. The bottom outer wall of the outer wall 201 is fixedly connected with a bottom plate 205. By connecting the outer wall 201 with the bottom plate 205, the outer wall 201 and the outer shell 1 form a framework to protect the structure inside the wallboard. The top outer wall of the bottom plate 205 is fixedly connected with a number of waterproof layers 202. By contacting the multiple waterproof layers 202 with the outer wall 201, the moisture on both sides is prevented from corroding the interior. The outer wall of the number of waterproof layers 202 away from the outer wall 201 is fixedly connected with a partition plate 203. The heat preservation plate 204 is separated from the waterproof layer 202 by the partition plate 203. The top outer wall of the bottom plate 205 is fixedly connected with a heat preservation plate 204. The outer wall of the heat preservation plate 204 is fixedly connected with a number of slopes 206. A number of water storage grooves 207 are provided in the inner wall of the slope 206. The water vapor formed by the cooling alternation of the heat preservation plate 204 is converged by the slope 206 and the water storage groove 207 and flows into the drainage groove 208. The drainage groove 208 is provided in the inner wall of the bottom plate 205. The outer wall of the bottom plate 205 is fixedly connected with a separation net 209. The liquid is discharged outwards through the drainage groove 208, and the separation net 209 is used to prevent objects from entering the drainage groove 208. An installation mechanism 3 is provided on the outer wall of the outer shell 1.

[0031] The installation mechanism 3 includes a limit block 301. The outer wall of the limit block 301 is fixedly connected to the outer wall of the outer shell 1. A positioning hole 302 is provided in the inner wall of the limit block 301. The moving distance of the positioning shell 305 in the limit block 301 is limited by the positioning hole 302. A number of threaded sleeves 303 are fixedly connected to the outer wall of the outer shell 1 away from the limit block 301. A hollow fixed tube 304 is threadedly connected to the inner wall of the threaded sleeve 303. By rotating the hollow fixed tube 304 inside the threaded sleeve 303, the hollow fixed tube 304 is connected to the threaded sleeve 303. The bottom outer wall of the hollow fixed tube 304 is fixedly connected with a positioning shell 305. A number of limit holes 307 are provided in the inner wall of the positioning shell 305. A number of I-shaped chutes 306 are provided in the inner wall of the hollow fixed tube 304. A telescopic rod 309 is slidably connected to the inner wall of the hollow fixed tube 304. A number of positioning blocks 310 are fixedly connected to the outer wall of the telescopic rod 309. By sliding the telescopic rod 309 in the hollow fixed tube 304, the positioning block 310 is driven to slide in the I-shaped chute 306. Due to the shape of the I-shaped chute 306, the position of the telescopic rod 309 in the hollow fixed tube 304 is changed, and the I-shaped chute 306 catches the positioning block 310. The outer wall of the positioning block 310 is slidably connected to the inner wall of the I-shaped chute 306. The top outer wall of the telescopic rod 309 is fixedly connected with a push rod 308. By the push rod 308, it is convenient to push the position of the telescopic rod 309 in the hollow fixed tube 304. A pressure spring 311 is fixedly connected to the inner wall of the telescopic rod 309 close to the push rod 308. A spring 316 is fixedly connected to the bottom of the inner wall of the hollow fixed tube 304.

[0032] One end of the outer wall of the spring 316 away from the positioning shell 305 is fixedly connected with a connecting plate 312. The movement of the telescopic rod 309 pushes the connecting plate 312 to move and squeezes the spring 316 at the bottom of the connecting plate 312. A plurality of positioning seats 313 are fixedly connected to the outer wall of the connecting plate 312. A hollow rod 314 is rotatably connected to the inner wall of the positioning seat 313. The movement of the connecting plate 312 drives the positioning seat 313 to move and drives the hollow rod 314 to move. A positioning rod 315 is slidably connected to the inner wall of the hollow rod 314. The outer wall of the positioning rod 315 is fixedly connected with the outer wall of the positioning shell 305. By restricting the positioning rod 315 on the positioning shell 305, the hollow rod 314 can rotate around the positioning rod 315 and slide along the positioning rod 315 at the same time. The outer wall of the hollow rod 314 is clamped with the inner wall of the positioning hole 302.

[0033] A specific application of this embodiment is:

[0034] When the staff needs to use the device, place multiple wall panels in one position. Then, make the connecting block 102 on the left side of one wall panel contact the limiting groove 101 on the right side of another wall panel, and let the connecting block 102 slide along the limiting groove 101, so as to quickly join the two wall panels together. Subsequently, push the two wall panels together vertically, and insert the hollow fixed tube 304 into the threaded sleeve 303. By twisting the hollow fixed tube 304, its surface moves downward along the thread inside the threaded sleeve 303. Then, the hollow fixed tube 304 pushes the positioning shell 305, making the positioning shell 305 fully inserted into the limiting block 301. Subsequently, rotate and push the push rod 308, so that the push rod 308 drives the telescopic rod 309 to move. Since the I-shaped chute 306 is opened inside the hollow fixed tube 304, and multiple positioning blocks 310 are connected to the outside of the telescopic rod 309 and are restricted in the I-shaped chute 306. Therefore, after the telescopic rod 309 rotates a certain angle, the positioning block 310 can slide downward along the I-shaped chute 306. By rotating the push rod 308 again, the positioning block 310 slides horizontally along the I-shaped chute 306, so that the I-shaped chute 306 limits the longitudinal movement ability of the positioning block 310. During the movement of the telescopic rod 309, the front end of the telescopic rod 309 will push the connecting plate 312, and let the connecting plate 312 squeeze the spring 316 at the bottom. The elastic force of the spring 316 restricts the movement range of the connecting plate 312. The movement of the connecting plate 312 drives multiple positioning seats 313 to move, and the positioning seats 313 drive the hollow rod 314 to move. Since the hollow rod 314 is restricted by the positioning rod 315, the hollow rod 314 will rotate around the positioning rod 315. At the same time, let the positioning rod 315 slide along the chute inside the hollow rod 314, so that the front end of the hollow rod 314 is inserted into the positioning hole 302, and the device is clamped in the limiting block 301. The same applies to the other four corners. At this time, the upper and lower two wall panels are installed. When in use, the waterproof layer 202 on the rear side of the outer wall 201 can prevent the moisture inside and outside the room from entering the interior of the wall panel. At the same time, use the isolation board 203 to separate the heat preservation board 204 from the outer wall 201, and leave a gap between the heat preservation board 204 and the isolation board 203 to relieve the problem that the heat preservation material expands due to the alternation of cold and heat and causes problems with the wall panel. At the same time, when the temperatures inside and outside the room are inconsistent, the water droplets generated by the alternation of cold and heat will condense on the surface of the heat preservation board 204. Through the slopes 206 on both sides of the heat preservation board 204, the water droplets can flow to the bottom of the slopes 206, and the water droplets are gathered together through multiple water storage grooves 207 opened on the slopes 206. By opening the drainage groove 208 in the bottom plate 205 and making the drainage groove 208 communicate with the water storage groove 207, and the drainage groove 208 slopes towards the outside of the wall panel. Therefore, the liquid flowing into the drainage groove 208 through the water storage groove 207 will flow outwards. And a separation net 209 is arranged at the part where the drainage groove 208 contacts the outside world, and the separation net 209 is used to prevent objects from entering the interior of the wall panel through the drainage groove 208.
