Composite thermal insulation formwork for building exterior walls (no removal required)

Abstract

This invention relates to the field of building exterior wall technology, specifically to a composite thermal insulation template for building exterior walls that does not require disassembly. It includes two mounting rods, with a positioning frame on the front of each rod and an insulation board on the front of the positioning frame. Through the linkage of the mounting rods, positioning frame, and insulation board, and the multi-dimensional positioning and clamping action of the insulation board installation, the insulation board and positioning frame can be firmly locked in the pre-set installation position on the wall before cement pouring. This effectively solves the problem of displacement of the positioning components due to internal pressure when the poured cement has not fully solidified. It avoids problems such as misalignment of fixing nails and excessive gaps in the insulation board splicing caused by positioning displacement. This ensures both the firmness of the template installation and the tightness of the insulation board splicing, guaranteeing the overall thermal insulation performance and structural stability of the exterior wall. A single installation action of pushing the insulation board simultaneously completes two processes: side clamping and fixing of the insulation board and overall locking of the positioning frame.

Description

Technical Field

[0001] This invention relates to the field of building exterior wall technology, and more specifically, to a composite thermal insulation formwork for building exterior walls that does not require dismantling. Background Technology

[0002] Composite insulation boards are exterior wall insulation components made by combining insulation materials with different functions and properties through physical or chemical methods. They can simultaneously take into account structural strength, thermal insulation performance and weather resistance, meeting the multi-dimensional usage needs of building exterior walls. In the current construction of building exterior wall insulation, the formwork-free method involves casting the insulation formwork and the structural wall at one time, which can be used directly as the exterior wall insulation layer without removing the formwork. This can effectively shorten the construction cycle and reduce construction costs.

[0003] According to patent document CN120061486B, a composite thermal insulation template for exterior walls that can be easily removed is disclosed. This invention solves the problem of insufficient bonding force between the internally threaded cylinder and the material in the inserted thermal insulation template, relating to the field of exterior wall insulation structure technology, and particularly to a composite thermal insulation template for exterior walls that can be easily removed. It includes a base wall, with a thermal insulation module on one side of the base wall. A pre-reserved positioning component is installed on the thermal insulation module. The pre-reserved positioning component has internal threads connected to fixing steel nails extending into the base wall. The pre-reserved positioning component includes a positioning cylinder inserted into the thermal insulation module during its fabrication. The tail end of the positioning cylinder is connected to a sealing structure for closing the tail end opening when it is directly inserted into the thermal insulation module before the material has solidified. This invention effectively achieves integration with the building's thermal insulation and structure while meeting the requirements of exterior wall insulation. Furthermore, the internally threaded cylinder forms a mechanical interlock within the thermal insulation module, effectively preventing the internally threaded cylinder from rotating or loosening under stress.

[0004] When installing composite insulation formwork for exterior walls, it is usually fixed by pouring cement on-site. However, if the cement has not fully hardened during the formwork pouring process, the pressure generated inside the cement may cause the pre-installed positioning components to shift. This shift can cause the fixing nails, which should be precisely aligned, to not be accurately aligned with the pre-drilled holes, thus affecting the secure installation of the formwork. This situation not only slows down the on-site construction progress but may also result in excessive gaps between the insulation boards, thereby affecting the overall insulation performance and structural stability of the exterior wall. Therefore, ensuring that the cement is fully hardened and the positioning components are firmly fixed and do not shift is crucial for ensuring construction quality and efficiency. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, this invention provides a non-removable composite thermal insulation template for building exterior walls. The technical problem this invention aims to solve is that when the poured cement has not fully solidified, the pressure generated inside the cement may cause the pre-reserved positioning components to shift. This shift can cause the fixing nails, which should be precisely aligned, to fail to accurately align with the pre-drilled holes, thus affecting the secure installation of the template. This situation not only slows down the on-site construction progress but may also result in excessively large gaps between the insulation boards, thereby affecting the overall thermal insulation performance and structural stability of the exterior wall.

[0012] As a further embodiment of the present invention: the limiting component includes a central upright plate, and guide rails are fixedly connected to the left and right sides of the top and bottom front sides of the central upright plate. Rotating rods are rotatably connected to the top and bottom front sides of the central upright plate. A stop block is fixedly connected to the side of the two sets of rotating rods on the front side that are close to each other. The outer sides of the two sets of rotating rods at the top and the two sets of rotating rods at the bottom are rotatably connected to the inner sides of the two sets of side slides at the top and bottom.

[0013] As a further embodiment of the present invention: the top and bottom of the left and right sides of the central upright plate are slidably connected to side sliding plates, the front sides of the inner sides of the two sets of side sliding plates at the top and bottom are fixedly connected to inverted L-shaped clamps, the left and right sides of the rear sides of the two inverted L-shaped clamps are fixedly connected to columnar connecting rods, the rear ends of the two sets of columnar connecting rods are fixedly connected to concave sliders, the outer sides of the two concave sliders are fixedly connected to columnar push-pull uprights, the outer ends of the two columnar push-pull uprights extend to the outer sides of the two central guide blocks, and the outer ends of the two columnar push-pull uprights are fixedly connected to top positioning plates.

[0014] As a further embodiment of the present invention: a sleeve block is fixedly connected to the outer wall of each of the two columnar push-pull uprights near the concave slider, an elliptical abutment plate is fixedly connected to the inner side of each of the two sleeve blocks, the rear side of each of the two concave sliders is slidably connected to the outer side of the two sets of guide rails, and the inner wall of each of the two concave sliders is sleeved on the outer wall of the two sets of abutment blocks.

[0015] As a further embodiment of the present invention: the connecting assembly includes a front plate, a central positioning block is fixedly connected to the middle of the rear side of the front plate, columnar horizontal push rods are fixedly connected to both sides of the top and bottom of the middle of the rear side of the front plate, the rear ends of the left and right sets of columnar horizontal push rods extend to the inner side of the two mounting rods, and the rear ends of the left and right sets of columnar horizontal push rods are fixedly connected to vertical push-pull plates.

[0016] As a further embodiment of the present invention: hinge blocks are fixedly connected to the top and bottom of the front sides of the two vertical push-pull plates, and second rotating rods are rotatably connected to the left and right sides of the front sides of the two hinge blocks, and retractable connecting arms are rotatably connected to the outer sides of the two sets of second rotating rods.

The rear side of the insulation board body is fixedly connected to the front side of the front board on one side inside the two insulation board positioning side plates.

[0019] The beneficial effects of this invention are as follows:

[0020] This invention, by incorporating an installation rod, a positioning frame, and an insulation board, achieves the linkage between the insulation board installation and pushing action and the multi-dimensional positioning and clamping action. Before cement pouring, the insulation board and the positioning frame can be firmly locked in the preset installation position on the wall. This effectively solves the problem of displacement of the positioning component due to internal pressure when the poured cement has not fully solidified. It also avoids the problems of the fixing nails not aligning with the holes and the excessive gaps in the splicing of the insulation board caused by the positioning displacement. This ensures both the firmness of the template installation and the tightness of the insulation board splicing, thus guaranteeing the overall thermal insulation performance and structural stability of the exterior wall.

[0021] By pushing the insulation board in a single installation action, the two processes of clamping and fixing the side of the insulation board and locking the overall position of the positioning frame can be completed simultaneously. There is no need for staff to manually calibrate and align or adjust multiple positioning components one by one. This greatly reduces the difficulty of on-site installation and positioning, effectively shortens the construction preparation time, and improves on-site construction efficiency.

[0022] The retraction distance between the two outer clamps can be flexibly changed by adjusting the push stroke of the insulation board, adapting to the installation requirements of insulation boards of different sizes. The entire adaptation process does not require replacement of positioning frame parts or modification of the existing structure, making the device more versatile and adaptable.

[0023] The positioning frame, as an internal support structure, can be directly retained inside the poured wall, eliminating the need for the demolding process after the traditional insulation formwork construction. This reduces the generation of construction waste, further simplifies the overall construction process, and lowers the labor and time costs of construction.

[0024] The device, through multi-layer clamping and locking combined with circumferential frame limiting, can firmly fix the insulation board in the preset installation position for a long time, effectively preventing the insulation board from loosening and shifting after long-term use. It significantly improves the overall stability and service life of the building's exterior wall insulation structure, and has multiple advantages such as high construction efficiency, structural stability, strong adaptability, and green environmental protection.

The inner sides of both upper and lower sets of vertical sliding plates 2117 are slidably connected to the multiple sides of the front of the central horizontal guide plate 2113. The limiting component 212 includes a central upright plate 2121. The top and bottom of the front of the central upright plate 2121 are...

Abutments 2126 are fixedly connected to the front sides of the two sets of rotating rods 2125 that are close to each other. The outer sides of the two sets of rotating rods 2125 at the top and the two sets of rotating rods 2125 at the bottom are rotatably connected to the inner sides of the two sets of side slides 2127 at the top and bottom. Side slides 2127 are slidably connected to the top and bottom of both the left and right sides of the central upright plate 2121. Inverted L-shaped clamps 2128 are fixedly connected to the front sides of the inner sides of the two sets of side slides 2127 at the top and bottom. Columnar connecting rods 2129 are fixedly connected to the left and right sides of the rear sides of the two inverted L-shaped clamps 2128. Each of the two concave sliders 21210 is fixedly connected to its rear end. A columnar push-pull rod 2122 is fixedly connected to the outer side of each of the two concave sliders 21210. The outer ends of the two columnar push-pull rods 2122 extend to the outer sides of the two central guide blocks 2116. A top positioning plate 2123 is fixedly connected to the outer ends of the two columnar push-pull rods 2122. A sleeve block 21211 is fixedly connected to the side of the outer wall of each of the two columnar push-pull rods 2122 near the concave slider 21210. An elliptical abutment plate 21212 is fixedly connected to the inner side of each of the two sleeve blocks 21211. The rear sides of the two concave sliders 21210 are slidably connected to the outer sides of the two sets of guide rails 2124. The inner walls of the two concave sliders 21210 are fitted onto the outer walls of the two sets of abutments 2126.The connecting assembly 22 includes a front plate 221. A central positioning block 228 is fixedly connected to the middle of the rear side of the front plate 221. Columnar horizontal push rods 222 are fixedly connected to both the top and bottom sides of the middle rear side of the front plate 221. The rear ends of both sets of columnar horizontal push rods 222 extend to the inner sides of two mounting rods 1. Vertical push-pull plates 223 are fixedly connected to the rear ends of both sets of columnar horizontal push rods 222. Hinges 224 are fixedly connected to the top and bottom of the front sides of the two vertical push-pull plates 223. Second rotating rods 225 are rotatably connected to the left and right sides of the front sides of the two hinge blocks 224. The two sets of second rotating rods 225... The outer sides are rotatably connected to retractable connecting arms 226. The front sides of both sets of retractable connecting arms 226 are fixedly connected to outer clamping plates 227. The rear sides of both outer clamping plates 227 are slidably connected to the left and right sides in front of the central horizontal guide plate 2113. The top and bottom of both outer clamping plates 227 are fixedly connected to the inner sides of the left and right sets of horizontal retractable rods 2118. The insulation board 3 includes an insulation board body 31. The left and right sides of the rear side of the insulation board body 31 are fixedly connected to insulation board positioning side plates 32. The rear side of the insulation board body 31 is fixedly connected to the front side of the front plate 221 on one side inside the two insulation board positioning side plates 32.

[0039] When it is necessary to install the insulation board 3, first fix the insulation board 3 to the front side of the front plate 221 with screws, and fix the two sets of side L-shaped connecting plates 2114 to the outside of the two mounting rods 1 with screws. At this time, the staff pushes the insulation board 3 to the rear side, and the insulation board 3 drives the front plate 221 to move backward in sync. The front plate 221 drives the two sets of columnar horizontal push rods 222 to slide backward. The columnar horizontal push rods 222 push the rear vertical push-pull plate 223 to move backward in sync. The vertical push-pull plate 223 pushes the second rotating rod 225 to rotate through the hinge block 224. The second rotating rod 225 drives the retractable connecting arm 226 to move in sync. The retractable connecting arm 226 pushes the two outer clamping plates 227 to retract towards each other along the middle horizontal guide plate 2113, so that the inner side of the two outer clamping plates 227 is attached to the two sides of the insulation board body 31. This can achieve the side clamping and fixing of the insulation board body 31 without the need for staff to manually align and calibrate, reducing the difficulty of installation and positioning.

[0040] As the vertical push-pull plate 223 moves backward, the outer clamping plate 227 simultaneously drives the left and right sets of horizontal retracting and expanding rods 2118 to move synchronously. The horizontal retracting and expanding rods 2118 drive the left and right sets of vertical sliding plates 2117 to slide towards each other along the horizontal guide rod 2111 via the retracting and expanding sliders 2119, completing the inward and outward retraction and positioning action. The two sets of horizontal retracting and expanding rods 2118 rotate inward, which drives the two sets of rotating rods 2125 to retract and rotate inward via the two sets of retracting and expanding sliders 2119, thereby driving the abutment blocks 2126 to rotate inward synchronously. The two abutment blocks 2126 apply force to the inner wall of the elliptical abutment plate 21212. Two sets of concave sliders 21210 are pushed to slide inward along the guide rail 2124, thereby driving two inverted L-shaped clamping plates 2128 to clamp the outer wall of the positioning block 228 in the middle of the rear side of the front plate 221. Two columnar push-pull uprights 2122 pull two top positioning plates 2123 to fit against the outer side of the upper and lower sets of side L-shaped connecting plates 2114. The two sides of the two top positioning plates 2123 are positioned with the two sets of guide rails 2124 by screws, further locking the overall installation position of the positioning frame 2, preventing the insulation board 3 from shifting after installation, and improving the overall installation stability.

[0041] When it is necessary to adapt and install insulation boards 3 of different sizes, it is only necessary to adjust the backward push stroke of the front plate 221. The greater the push stroke, the greater the backward movement distance of the vertical push-pull plate 223, the greater the rotation angle of the second rotating rod 225, and the smaller the gap between the two outer clamping plates 227 when they close towards each other. This allows for the adaptation of smaller insulation boards 3. Conversely, the smaller the push stroke, the greater the gap between the two outer clamping plates 227 when they close. This allows for the adaptation of larger insulation boards 3. The entire adaptation process does not require the replacement of any parts of the positioning frame 2. Multi-dimensional clamping and positioning are completed synchronously through the pushing action, resulting in stronger adaptability and higher installation efficiency.

[0042] After the overall installation is completed, the frame structure composed of the horizontal guide rod 2111, the vertical guide rod 2112 and the middle horizontal guide plate 2113 can circumferentially limit the installation position of the entire insulation board 3. The side L-shaped connecting plate 2114 and the rear connecting rod 2115 form a close clamp from the outside and inside of the installation rod 1 respectively. With the locking of the top positioning plate 2123, the positioning frame 2 can be firmly fixed between the two installation rods 1, preventing the insulation board 3 from loosening and shifting after long-term use, and improving the overall stability and service life of the wall insulation structure.

[0043] After installing multiple positioning frames 2 and insulation boards 3 on the outer wall of the mounting rod 1, ensuring that the multiple insulation boards 3 are in contact, cement pouring can then be carried out. The positioning frames 2, as an internal support structure, do not need to be removed and can remain directly inside the wall, avoiding the construction waste generated after the removal of traditional insulation templates. At the same time, the demolding process is eliminated, simplifying the overall construction process. The entire structure completes two processes simultaneously through the installation and pushing action: clamping the side of the insulation board 3 and locking the positioning frame 2 as a whole. The actions of each component are linked together, eliminating the need for additional manual adjustment of multiple clamping parts, greatly reducing the operational threshold of on-site construction, and effectively improving construction efficiency while ensuring the stability of the installation structure.

[0044] Working principle of the invention: When the insulation board 3 needs to be installed, the insulation board 3 is first fixed to the front side of the front plate 221 by screws, and the two sets of side L-shaped connecting plates 2114 are fixed to the outer sides of the two mounting rods 1 by screws. At this time, the worker pushes the insulation board 3 backward, and the insulation board 3 drives the front plate 221 to move backward in sync. The front plate 221 drives the two sets of columnar horizontal push rods 222 to slide backward. The columnar horizontal push rods 222 push the rear vertical push-pull plate 223 to move backward in sync. The vertical push-pull plate 223 pushes the second rotating rod 225 to rotate through the hinge block 224. When the second rotating rod 225 moves, it drives the retractable connecting arm 226 to move synchronously. The retractable connecting arm 226 pushes the two outer clamping plates 227 to retract towards each other along the central horizontal guide plate 2113, so that the inner sides of the two outer clamping plates 227 are attached to the two sides of the insulation board body 31. This achieves side clamping and fixing of the insulation board body 31, eliminating the need for manual alignment and calibration by the staff, and reducing the difficulty of installation and positioning. When the vertical push-pull plate 223 moves backward, the outer clamping plates 227 simultaneously drive the two sets of horizontal retractable rods 2118 to move synchronously. The retracting slider 2119 drives the two sets of vertical sliding plates 2117 to slide towards each other along the horizontal guide rod 2111, completing the inward and outward retraction and positioning action. The two sets of horizontal retracting rods 2118 rotate inward, which drives the two sets of rotating rods 2125 to retract and rotate inward through the two sets of retracting sliders 2119, thereby driving the abutment blocks 2126 to rotate inward synchronously. The two abutment blocks 2126 exert force on the inner wall of the elliptical abutment plate 21212, pushing the two sets of concave sliders 21210 to slide inward along the guide rail rod 2124, thereby driving the two inverted L-shaped clamping plates 2128 to clamp the rear side of the front plate 221. The outer wall of the central positioning block 228 is used to pull the two top positioning plates 2123 to fit against the outer side of the upper and lower sets of side L-shaped connecting plates 2114 through two columnar push-pull uprights 2122. The two sides of the two top positioning plates 2123 are then positioned with the two sets of guide rails 2124 by screws, further locking the overall installation position of the positioning frame 2, preventing the insulation board 3 from shifting after installation, and improving the overall installation stability. After the multiple positioning frames 2 and insulation boards 3 are installed on the outer wall of the installation rod 1 and the multiple insulation boards 3 are in contact, the cement pouring operation can then be carried out.
