Description

Technical Field

[0001] This utility model relates to the field of building exterior wall technology, specifically a modular building exterior wall insulation structure. Background Technology

[0002] With the continuous development and widespread application of modular buildings, the importance of external wall insulation structures as a key component in improving building energy efficiency and living comfort is self-evident. The splicing of insulation panels is the core link in constructing external wall insulation structures, directly affecting the insulation effect and the overall quality of the building.

[0003] Currently, the splicing of insulation boards relies heavily on manual experience and visual inspection due to the lack of effective positioning and fixing mechanisms. This makes dimensional errors during splicing extremely common. A frequent issue is that the edges of adjacent insulation boards cannot be precisely aligned, resulting in unevenness or excessively large gaps. This necessitates repeated rework, requiring workers to expend extra time and manpower to adjust or re-splice the insulation boards. This not only delays construction progress but also increases costs, contradicting the efficient and economical principles of modular construction.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a modular building exterior wall insulation structure in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a modular building exterior wall insulation structure to solve the problem mentioned in the background art that, during the current insulation board splicing operation, due to the lack of an effective positioning and fixing mechanism, construction workers mainly rely on manual experience and visual observation to align the insulation boards.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A modular building exterior wall insulation structure includes a protective exterior wall, a positioning mechanism, and a connecting mechanism. The protective exterior wall has sound-insulating cotton on both sides of its interior, and an insulation core is located between a pair of sound-insulating cotton pieces inside the protective exterior wall. The connecting mechanism includes a first connecting block and a second connecting block, which are respectively disposed at the upper and lower ends of the protective exterior wall. The first connecting block has several mounting holes, and several positioning blocks are slidably inserted into both sides of the second connecting block. The positioning mechanism includes an I-beam, with several positioning holes on both sides of its upper interior that can engage with the positioning blocks. The bottom end of the I-beam is inserted into the first connecting block.

[0007] Furthermore, the connecting mechanism also includes a lead screw, which is disposed inside the second connecting block, and the two ends of the lead screw are rotatably connected to the two ends inside the second connecting block.

[0008] The beneficial effect of adopting the above scheme is that the lead screw of the connecting mechanism is installed inside the second connecting block, and its two ends are rotatably connected to the two ends inside the second connecting block. By rotating the lead screw, the position of the sleeve threadedly connected to it can be controlled, thereby adjusting the extension or retraction of the positioning block, which facilitates positioning operations during installation.

[0009] Furthermore, the lead screw is threaded with several sleeves, one end of each sleeve is slidably connected to the inner sides of the second connecting block, and a trapezoidal block is fitted onto one end of each sleeve.

[0010] The beneficial effects of adopting the above scheme are that the sleeve connected by the thread on the lead screw has one end and both sides of its sliding connection with the inside sides of the second connecting block, which ensures that the sleeve can only move along the axial direction of the lead screw when the lead screw rotates and will not rotate. The trapezoidal block fitted on one end of the sleeve can interact with the wedge block on the positioning block when the lead screw rotates and drives the sleeve to move, pushing the positioning block to extend outward or retract inward, thereby realizing the control of the position of the positioning block and improving the accuracy of module connection positioning.

[0011] Furthermore, connecting plates are installed on both opposite sides of the positioning block, and wedge blocks are symmetrically installed on both opposite sides of each pair of connecting plates. Both opposite sides of each pair of wedge blocks abut against the two sides of the trapezoidal block, and tension springs are fixedly installed between the upper and lower ends of both opposite sides of each pair of connecting plates.

[0012] The beneficial effects of the above scheme are that the connecting plate and the wedge block on the connecting plate installed on the opposite side of the positioning block abut against the trapezoidal block at one end of the sleeve. When the trapezoidal block moves under the drive of the sleeve, it pushes the positioning block to move through the wedge block. The tension springs fixedly installed between the upper and lower ends of each pair of connecting plates can pull the positioning block back when the trapezoidal block and the wedge block separate, which facilitates the disassembly and reinstallation of the module and also ensures the positional stability of the positioning block in the non-working state.

[0013] Furthermore, a reserved hole is provided at one end of the second connecting block, and an internal hexagonal connector is rotatably connected inside the reserved hole. The central shaft on one side of the internal hexagonal connector is connected to one end of the lead screw.

[0014] The beneficial effect of adopting the above solution is that the internal hexagonal connector rotatably connects to the pre-drilled hole at one end of the second connecting block, and its central shaft is connected to the lead screw on one side. By using an internal hexagonal wrench in conjunction with the internal hexagonal connector, the lead screw can be easily rotated, making the operation simple and convenient.

[0015] Furthermore, an L-shaped mating groove is provided at one end of the I-beam, the first connecting block, and the protective outer wall, and an L-shaped plug is installed at the other end of the I-beam, the first connecting block, and the protective outer wall for insertion into the L-shaped mating groove.

[0016] The beneficial effects of adopting the above scheme are that, during the module installation process, the L-shaped docking groove opened at one end of the I-beam, the first connecting block, and the protective outer wall, and the L-shaped insert installed at the other end, the L-shaped insert of the adjacent module can be inserted into the L-shaped docking groove to achieve a tight connection between the modules. This L-shaped structure not only enhances the connection strength between the modules, but also further improves the accuracy and stability of the module installation, making the entire insulation structure more robust.

[0017] Furthermore, the inner bottom end of the I-beam is provided with threaded grooves on one side of each of the mounting holes, and a number of fixing bolts are movably inserted into the bottom side of the I-beam, with one end of each fixing bolt passing through the mounting hole and threadedly connected to the threaded groove.

[0018] The beneficial effect of adopting the above scheme is that the threaded groove embedded at the bottom of the I-beam on one side of the mounting hole, together with the fixing bolt that is movably inserted on the bottom side, with one end of the fixing bolt passing through the mounting hole on the first connecting block and threadedly connected to the threaded groove, fixes the I-beam and the first connecting block together, which enhances the connection stability between the I-beam and the protective outer wall and ensures the reliability of the entire insulation structure during use.

[0019] Furthermore, the protective outer wall is made of galvanized steel sheet, and the insulation core is made of polyurethane foam.

[0020] The beneficial effects of adopting the above scheme are that the protective outer wall is made of galvanized steel plate, which has good corrosion resistance and strength, and can effectively protect the internal sound insulation cotton and heat insulation core, extending the service life of the heat insulation structure. The heat insulation core is made of polyurethane foam, which has excellent heat insulation performance, low density and light weight, which can not only ensure good heat insulation effect, but also reduce the weight of the entire building and reduce construction costs.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: the modular building exterior wall insulation structure uses the protective exterior wall as the outer layer of the entire insulation structure, and the sound insulation cotton on both sides inside can effectively block sound transmission and improve the sound insulation effect of the building. The insulation core located between the sound insulation cotton can reduce heat transfer and achieve good insulation performance. The first connecting block and the second connecting block of the connecting mechanism are respectively set at the upper and lower ends of the protective exterior wall, which facilitates connection without damaging the protective exterior wall. The mounting holes on the first connecting block facilitate the installation and connection of the I-beam plate. The positioning blocks slidably inserted on both sides of the second connecting block, together with the positioning holes on the I-beam plate of the positioning mechanism, can realize precise positioning between modules and ensure the accuracy and stability of installation. The bottom end of the I-beam plate is inserted into the first connecting block, which further enhances the connection strength of the structure. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1 Please see Figure 1 - Figure 6This utility model provides a technical solution: a modular building exterior wall insulation structure, including a protective exterior wall 100, a positioning mechanism 101, and a connecting mechanism 102. Sound insulation cotton 106 is provided on both sides of the interior of the protective exterior wall 100, and an insulation core 107 is provided between a pair of sound insulation cotton 106 inside the protective exterior wall 100. The connecting mechanism 102 includes a first connecting block 10201 and a second connecting block 10203, which are respectively disposed at the upper and lower ends of the protective exterior wall 100. The first connecting block 10201 has several mounting holes 10208, and several positioning blocks 10204 are slidably inserted into both sides of the second connecting block 10203. The positioning mechanism 101 includes an I-beam 10101, with several positioning holes 10102 on both sides of the upper end of the I-beam 10101 that can engage with the positioning blocks 10204. The bottom end of the I-beam 10101 is connected to the first connecting block 10208. 1. The protective outer wall 100 serves as the outer layer of protection for the entire insulation structure. The sound insulation cotton 106 on both sides of the interior can effectively block sound transmission and improve the sound insulation effect of the building. The insulation core 107 located between the sound insulation cotton 106 can reduce heat transfer and achieve good insulation performance. The first connecting block 10201 and the second connecting block 10203 of the connecting mechanism 102 are respectively set at the upper and lower ends of the protective outer wall 100, which facilitates connection without damaging the protective outer wall 100. The mounting hole 10208 on the first connecting block 10201 facilitates the installation and connection of the I-beam 10101. The positioning blocks 10204 slidably inserted on both sides of the second connecting block 10203, together with the positioning hole 10102 on the I-beam 10101 of the positioning mechanism 101, can achieve precise positioning between modules and ensure the accuracy and stability of installation. The bottom end of the I-beam 10101 is inserted into the first connecting block 10201, which further enhances the connection strength of the structure.

[0026] Please see Figure 1 - Figure 6The connecting mechanism 102 also includes a lead screw 10209, which is disposed inside the second connecting block 10203. Both ends of the lead screw 10209 are rotatably connected to the two ends inside the second connecting block 10203. A plurality of sleeves 10210 are threaded onto the lead screw 10209. One end of each sleeve 10210 is slidably connected to the two sides inside the second connecting block 10203. A trapezoidal block 10211 is fitted onto one end of each sleeve 10210. A connecting plate 10202 is installed on the two opposite faces of each pair of positioning blocks 10204. Wedge blocks 10207 are symmetrically installed on the two opposite faces of each pair of connecting plates 10202. The two opposite faces of each pair of wedge blocks 10207 abut against the two sides of the trapezoidal block 10211. Each pair of connecting plates 10202 has a tension spring 10212 fixedly installed between the upper and lower ends of the two opposite surfaces. A pre-drilled hole 10205 is provided at one end of the second connecting block 10203. An internal hexagonal connector 10206 is rotatably connected inside the pre-drilled hole 10205. The central shaft on one side of the internal hexagonal connector 10206 is connected to one end of a lead screw 10209. The lead screw 10209 of the connecting mechanism 102 is installed inside the second connecting block 10203, and its two ends are rotatably connected to the two ends inside the second connecting block 10203. By rotating the lead screw 10209, the position of the threaded sleeve 10210 can be controlled, thereby adjusting the extension or retraction of the positioning block 10204, facilitating positioning operations during installation. The sleeve 10210, threaded onto the screw 10209, has one end slidably connected to the two sides of the interior of the second connecting block 10203. This ensures that the sleeve 10210 can only move axially along the screw 10209 when the screw 10209 rotates, and will not rotate. A trapezoidal block 10211 fitted onto one end of the sleeve 10210 interacts with a wedge-shaped block 10207 on the positioning block 10204 when the screw 10209 rotates and drives the sleeve 10210 to move. This wedge pushes the positioning block 10204 to extend outwards or retract inwards, controlling the position of the positioning block 10204 and improving the accuracy of module connection positioning. The connecting plate 10202 and the connecting plate 10203 are mounted opposite to the positioning block 10204. The wedge-shaped block 10207 on the upper part abuts against the trapezoidal block 10211 at one end of the sleeve 10210. When the trapezoidal block 10211 moves under the action of the sleeve 10210, the wedge-shaped block 10207 pushes the positioning block 10204 to move. The tension spring 10212 fixedly installed between the upper and lower ends of the opposite surfaces of each pair of connecting plates 10202 can pull the positioning block 10204 back when the trapezoidal block 10211 separates from the wedge-shaped block 10207, which facilitates the disassembly and reinstallation of the module and also ensures the positional stability of the positioning block 10204 in the non-working state. The internal hexagonal connector 10206 is rotatably connected in the pre-drilled hole 10205 at one end of the second connecting block 10203, and its central shaft is connected to the lead screw 10209 on one side.By using an Allen wrench and an Allen connector 10206, the lead screw 10209 can be easily rotated, making operation simple and convenient.

[0027] Please see Figure 1 - Figure 6 One end of the I-beam 10101, the first connecting block 10201, and the protective outer wall 100 is provided with an L-shaped mating groove 105. The other end of the I-beam 10101, the first connecting block 10201, and the protective outer wall 100 is provided with an L-shaped insert 104 that can be inserted into the L-shaped mating groove 105. The inner bottom end of the I-beam 10101 is provided with a threaded groove 10104 on one side of several mounting holes 10208. Several fixing bolts 10103 are movably inserted into the bottom side of the I-beam 10101. One end of the fixing bolt 10103 passes through the mounting hole 10208 and is threaded into the threaded groove 10104. The protective outer wall 100 is made of galvanized steel plate, and the insulation core 107 is made of polyurethane foam. The I-beam 10101, the first connecting block 10201, and the L-shaped docking groove 105 opened at one end of the protective outer wall 100 and the L-shaped insert 104 installed at the other end allow the L-shaped insert 104 of adjacent modules to be inserted into the L-shaped docking groove 105 during module installation, achieving a tight connection between modules. This L-shaped structure not only This design enhances the connection strength between modules and further improves the accuracy and stability of module installation, making the entire insulation structure more robust. The threaded groove 10104 embedded at the bottom of the I-beam 10101, located on one side of the mounting hole 10208, works in conjunction with a fixing bolt 10103 movably inserted at the bottom. One end of the fixing bolt 10103 passes through the mounting hole 10208 on the first connecting block 10201 and is threadedly connected to the threaded groove 10104, thus fixing the I-beam 10101 and the first connecting block 10201 together, strengthening the insulation structure. The connection stability between the I-beam 10101 and the protective outer wall 100 is ensured, guaranteeing the reliability of the entire insulation structure during use. The protective outer wall 100 is made of galvanized steel plate, which has good corrosion resistance and strength, effectively protecting the internal sound insulation cotton 106 and insulation core 107, extending the service life of the insulation structure. The insulation core 107 is made of polyurethane foam, which has excellent thermal insulation performance, low density, and light weight, ensuring good thermal insulation effect while reducing the weight of the entire building and lowering construction costs.

[0028] Working principle The protective outer wall 100 has sound insulation cotton 106 installed on both sides inside, with a thermal insulation core 107 sandwiched in the middle. It has a first connecting block 10201 and a second connecting block 10203 at its upper and lower ends, respectively. During initial installation, the bottom end of the I-beam 10101 is first inserted into the first connecting block 10201. Then, using fixing bolts 10103, one end of the fixing bolt 10103 passes through the mounting hole 10208 on the first connecting block 10201 and is threaded into the threaded groove 10104 embedded at the bottom of the I-beam 10101, thus firmly fixing the I-beam 10101 to the wall. The first connecting block 10201 enhances the connection stability between the I-beam 10101 and the protective outer wall 100. Next, the modules are positioned and connected. Adjacent modules are initially connected via L-shaped inserts 104 and L-shaped mating slots 105. Specifically, the L-shaped inserts 104 at one end of the I-beam 101, the first connecting block 10201, and the protective outer wall 100 are inserted into the corresponding L-shaped mating slots 105 at the end of the adjacent module, achieving a tight connection between the modules. This L-shaped structure enhances the connection strength and installation accuracy between the modules. Then, precise positioning is performed. By rotating the internal hexagonal connector 10206 inside the pre-drilled hole 10205 at one end of the second connecting block 10203 with an internal hexagonal wrench, the internal hexagonal connector 10206 drives the lead screw 10209 to rotate. Since the sleeve 10210 is threaded onto the lead screw 10209, and the two sides of one end of the sleeve 10210 are slidably connected to the two sides inside the second connecting block 10203, when the lead screw 10209 rotates, the sleeve 10210 can only move along the axial direction of the lead screw 10209. The trapezoidal block 10211 fitted at one end of the sleeve 10210 moves with the sleeve 10210, and is fixed. The wedge blocks 10207 on the positioning block 10204 interact with each other. When the trapezoidal block 10211 moves, it pushes the wedge blocks 10207, which in turn drives the positioning block 10204 to extend outward, so that the positioning block 10204 is inserted into the positioning holes 10102 on both sides of the upper end of the I-beam plate 10101, ensuring the accuracy and stability of the installation. When the module needs to be disassembled, the internal hexagonal connector 10206 is rotated in the opposite direction, so that the lead screw 10209 is reversed, and the sleeve 10210 drives the trapezoidal block 10211 to move in the opposite direction, and the trapezoidal block 10211 separates from the wedge blocks 10207.At this time, the tension spring 10212 between the upper and lower ends of the positioning block 10204 and the connecting plate 10202 opposite to the surface of the positioning block 10204 comes into play, pulling the positioning block 10204 back, making it easy to disassemble the module for reinstallation or adjustment. During use, the protective outer wall 100 serves as the outer layer of protection. Because it is made of galvanized steel plate, it has good corrosion resistance and strength, which can effectively protect the internal sound insulation cotton 106 and thermal insulation core 107, extending the service life of the thermal insulation structure. The sound insulation cotton 106 can effectively block the transmission of sound and improve the sound insulation effect of the building. The thermal insulation core 107 is made of polyurethane foam. Due to its excellent thermal insulation performance, low density and light weight, it can not only ensure good thermal insulation effect, but also reduce the weight of the entire building and reduce construction costs.

[0029] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Based on the technical solution of the present utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the present utility model.
