Description

Technical Field

[0001] The invention relates to the technical field of thermal insulation exterior wall panel installation, in particular to a prestressed steel tube truss thermal insulation exterior wall panel system and an installation method thereof. Background Art

[0002] During the installation of prestressed steel tube truss insulation exterior wall panels, the prestressed steel tube truss must first be placed vertically, and each insulation board (polyurethane insulation board, etc.) must be attached to the two sides of the prestressed steel tube truss in turn, and fixed with bolts and other fixing parts. Isolation boards are set up on the other two sides of the prestressed steel tube truss to form a cement pouring cavity with the installed insulation board and prestressed steel tube truss. At this time, cement is injected into it. After it is fully solidified, the isolation board and fixing parts are removed to form the predetermined exterior wall panels. The traditional prestressed steel tube truss insulation exterior wall panels still have the following problems during the installation process: First, since the side of the prestressed steel tube truss is a steel tube structure, multiple position corrections are required when laying the insulation board to align the insulation board with the side position of the prestressed steel tube truss. Multiple layers of insulation board need to be laid on the side of the prestressed steel tube truss, and the insulation board has a certain quality. Repeated laying work will increase the workload of the operators.

[0003] Second, in order to ensure stability during the pouring process, adhesive needs to be applied between the two insulation boards during the installation process. Since the insulation board will slide downward along the side of the installed insulation board during the laying process, the adhesive at the bottom end of the side of the insulation board will not adhere evenly, affecting the adhesion of the entire insulation board.

[0004] Third, after completing the installation of the insulation board, in order to determine the fit of the insulation board, it is necessary to measure the thickness through measuring equipment. This means that each time the insulation board is installed, a measurement is required, and the process is rather cumbersome.

[0005] In order to address the above problems, a prestressed steel tube truss thermal insulation exterior wall panel system and an installation method thereof are urgently needed. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 2 As shown, one of the purposes of the present invention is to provide a prestressed steel tube truss insulation exterior wall panel system, including a steel tube truss 10 and a plurality of insulation exterior panels 20 arranged on both sides of the steel tube truss 10, a bottom support plate 30 is placed at the bottom end of the steel tube truss 10, and side panels 40 are arranged on both sides of the top of the bottom support plate 30, and the side panels 40 include a pair of clamping plates 410 whose ends are plugged into each other, and the ends of the two clamping plates 410 are attached to each other to form an isolation surface, and the spliced ​​insulation exterior panels 20 and the steel tube truss 10 form a chamber for pouring cement; A limiting frame 50 is arranged between the two clamping plates 410 on the opposite sides. The limiting frame 50 includes a limiting horizontal plate 510 and a pair of sliders 520 arranged at both ends of the limiting horizontal plate 510. A gap for installing the insulation outer plate 20 is formed between the sliders 520 and the side surfaces of the steel tube truss 10 to locate the installation position of the insulation outer plate 20. A reset component is connected between the limiting horizontal plate 510 and the sliders 520 to apply a reaction force to the limiting horizontal plate 510 after horizontal displacement, so that it moves upward synchronously with the sliders 520, and the side surfaces of the insulation outer plate 20 after installation are squeezed to spread the adhesive between the side surfaces of the insulation outer plate 20 that are bonded to each other. Adjustment components are connected between the two ends of the slider 520 and the inner ends of the corresponding clamps 410, and during the horizontal displacement of the limiting cross plate 510 to form a gap, the adjustment components drive the corresponding clamps 410 to slide toward the middle position of the steel pipe truss 10, and the fitting state of the installed insulation outer panel 20 is determined by the displacement of the clamps 410.

[0021] During specific use, during the installation of the prestressed steel tube truss insulation exterior wall panel, first, the entire steel tube truss 10 is placed in the area formed between the top of the bottom support plate 30 and the side of the two side plates 40 to complete the position correction of the steel tube truss 10. At this time, the two limit frames 50 are respectively located on the other two sides of the steel tube truss 10, and a gap is reserved between the limit cross plate 510 and the side of the steel tube truss 10. The innermost insulation outer panel 20 is slid vertically downward along the gap formed by the two side plates 40, sliding downward in line with the side of the steel tube truss 10 and passing through the gap. The two side plates 40 are matched through the gap to form a limiting channel for the vertical sliding of the insulation outer panel 20. The position of the insulation outer panel 20 to be installed is corrected, and the insulation outer panel 20 is guided to the installation position without the need for secondary position correction, thereby improving the installation efficiency.

[0022] When installing the second insulation outer panel 20, since the limiting cross plate 510 is attached to the side of the insulation outer panel 20 under the action of the reset component, there is no gap between the two. At this time, it is necessary to slide the limiting cross plate 510 horizontally to make it slide along the sides of the two sliders 520 and re-form a gap with the sides of the installed insulation outer panel 20 for the installation of the second insulation outer panel 20. Since the two insulation outer panels 20 need to be coated with adhesive at their fitting positions during the splicing process, when the insulation outer panel 20 to be installed slides along the sides of the installed insulation outer panel 20, the adhesive will be affected by the friction generated by the contact surface between the two, causing the originally evenly laid adhesive to spread to its sides, and the lower the adhesive is, the more serious the diffusion range is. This is because the bottom end area of ​​the side of the insulation outer panel 20 has the widest contact range and is most affected. This makes the adhesion uniformity of the adhesive lower, so when installing the insulation outer panels 20 other than the innermost insulation outer panel 20 The limit cross plate 510 is then released to allow the limit cross plate 510 to be attached to the side of the insulation outer plate 20 at all times and to apply pressure to the contact position thereof. The limit cross plate 510 and a pair of sliders 520 connected thereto are driven by the weight of the insulation outer plate 20 itself to move vertically downward synchronously until the bottom end of the insulation outer plate 20 contacts the top end of the bottom support plate 30. At this time, the limit cross plate 510 is at the bottommost position. In order to install the next insulation outer plate 20, it is necessary to slide the limit cross plate 510 upward to drive the sliders 520 to move upward synchronously to the initial position. The reaction force provided by the reset component to the limit cross plate 510 will cause the limit cross plate 510 to always be attached to the side of the insulation outer plate 20 and to apply pressure to the side of the insulation outer plate 20. The adhesive adhered to the other side thereof is evenly spread through the insulation outer plate 20, thereby increasing the adhesion surface between the two insulation outer plates 20 and increasing the adhesion effect between the two.

[0023] In addition, by Figure 3-Figure 4As shown, the two clamping plates 410 are both slidably connected to the top of the bottom support plate 30, and a clamping plate 412 is provided on the side of one of the clamping plates 410, and a clamping slot 411 is provided on the side of the other clamping plate 410 to be plugged and matched with the clamping plate 412; Depend on Figure 5 As shown, the reset assembly includes a side groove 521, a limiting column 522 installed on the inner side of the side groove 521, and a limiting spring 523 sleeved on the outer side of the limiting column 522. Both ends of the limiting horizontal plate 510 are provided with side blocks that keep sliding with the inner ends of the side grooves 521 at corresponding positions. The side blocks are sleeved on the outer side of the limiting column 522, and one end of the limiting spring 523 is connected to the inner wall of the side groove 521, and the other end is connected to the side position of the side block. Depend on Figure 6-Figure 7 As shown, the positioning assembly includes a shift plate 530, which is fixed at the top position of the side block, and the shift plate 530 passes through the top of the slider 520 and extends into the inner end of the clamping plate 410. The inner end of the clamping plate 410 is provided with a limiting groove 420, and the slider 520 slides along the inner end of the limiting groove 420, and a plurality of wedge plates 421 are equidistantly arranged at the inner end of the limiting groove 420, and the wedge surface of the wedge plate 421 is aligned with the sliding direction of the limiting cross plate 510, the top cross-sectional dimension of the wedge plate 421 is smaller than the bottom cross-sectional dimension, and the width formed between the top side surface of the wedge plate 421 and the opposite side of the bottom end is exactly the same as the thickness of the insulation outer plate 20, and a protrusion is arranged at the top of the shift plate 530, and a groove for the sliding of the protrusion is reserved between the top of each wedge plate 421 and the top wall of the limiting groove 420.

[0024] When in use, when the limiting cross plate 510 slides horizontally away from the insulating outer panel 20 to form a gap, the limiting cross plate 510 will drive the side blocks set at its two ends to slide horizontally along the inner ends of the side grooves 521 at the corresponding positions, and apply pressure to the limiting springs 523 at the inner ends of the side grooves 521, causing them to be in a compressed state. At this time, the limiting springs 523 will provide a reaction force to the limiting cross plate 510 through the side blocks, causing the limiting cross plate 510 to fit the side of the insulating outer panel 20 to be installed, and when the limiting cross plate 510 clamps the insulating outer panel 20 to complete the installation work and reset, the reaction force is used to apply pressure to the side of the insulating outer panel 20, so that the adhesive adhered to the side of the insulating outer panel 20 is evenly spread; When the limit cross plate 510 is in the initial position, the protrusion at the top of the moving plate 530 is just located at the inner end of the slot, and the moving plate 530 can slide horizontally, and the moving plate 530 is fixed by the protrusion. At this time, the limit cross plate 510 can only drive the moving plate 530 to slide horizontally synchronously, and cannot move up and down, forming a gap with the installed insulation outer plate 20 until the insulation outer plate to be installed is The bottom end of the plate 20 extends into the gap, the limiting horizontal plate 510 is loosened, and the elastic force generated by the limiting spring 523 when it is reset drives the limiting horizontal plate 510 to the side of the insulation outer plate 20 to be installed, fixing the insulation outer plate 20 to be installed, and the moving plate 530 located above the limiting horizontal plate 510 will slide along the slot to the position above the top of the wedge plate 421. At this time, the side of the convex block at the top of the moving plate 530 is just aligned with the side of the top of the wedge plate 421. The limiting horizontal plate 510 in the clamping state 0 moves down synchronously with the slider 520, driving the shift plate 530 to slide along the wedge surface of the aligned wedge plate 421, and gradually applies thrust to the wedge surface during the downward movement, driving the entire limit groove 420 to slide in the sliding direction away from the limit horizontal plate 510, until the limit horizontal plate 510 clamps the insulation outer plate 20 to be installed to the top installation position of the bottom support plate 30, and the convex block at the top of the shift plate 530 just moves to the bottom of the side of the wedge plate 421. At this time, the entire limit groove 420 The moving distance is exactly equal to the thickness of the insulation outer panel 20 that has just been installed. At the same time, the card plate 412 on the side of the limit groove 420 extends to the inner end of the card groove 411 at the corresponding position, and the extension amount is also consistent with the thickness of the insulation outer panel 20 until the installation of all the insulation outer panels 20 is completed. At this time, the card plate 412 is just completely extended to the inner end of the card groove 411, and the sides of the two plywood 410 are completely fitted to form a closed isolation surface, that is, the length of the card plate 412 is an integer multiple of the thickness of the insulation outer panel 20.

[0025] Furthermore, a plurality of plug posts 413 are disposed at the inner end of the card slot 411, and an inner groove for plugging and matching with the plug posts 413 is formed at the inner end of the card plate 412, and the cross-section of the plug posts 413 and the inner groove is a T-shaped structure; A notch 430 is provided on the side of the top of the splint 410 , and a plurality of scale grooves are provided on the top of the notch 430 . A pair of L-shaped brackets 310 are provided on both sides of the top of the bottom support plate 30 . The L-shaped brackets 310 are L-shaped, and the top of the L-shaped brackets 310 are slidably connected to the notch 430 .

[0026] During the installation process, the two clamping plates 410 need to be separated from each other first to maximize the spacing between the two, and the side surfaces of the clamping plates 410 protrude from the side surfaces of the steel tube truss 10 to clamp and limit the two sides of the insulation outer plate 20. In order to ensure that the spacing between the two clamping plates 410 is the same each time, the positions of the clamping plates 410 are limited by setting the plug posts 413. When the two clamping plates 410 slide to the maximum spacing, the plug posts 413 just slide to the position of the inner groove port and cannot continue to slide, thereby limiting the sliding spacing of the plug posts 413 to maintain the same spacing during each installation process. At the same time, as the clamping plates 410 complete the sliding adjustment work, the corresponding The top of the L-shaped bracket 310 is perfectly fitted in the notch 430. During the installation of the insulation outer panel 20, each time the insulation outer panel 20 is installed, the splint 410 will be close to each other by the same distance as the thickness of the insulation outer panel 20 under the action of the shift plate 530 and the wedge plate 421. Correspondingly, the distance between the notch 430 at the top of the splint 410 and the top end face of the L-shaped bracket 310 is the thickness of the insulation outer panel 20. The operator can directly obtain the current installation status of the insulation outer panel 20 by reading the alignment position of the L-shaped bracket 310 and the scale groove, and determine whether the adhesion is completed, thereby eliminating the need for repeated measurements.

[0027] Furthermore, an end block 524 is provided at the end of the slider 520, a connecting groove is provided on the side of the L-shaped bracket 310 to maintain sliding with the end block 524, a column is provided at the top of the bottom support plate 30 near the other end of the slider 520, the column and the L-shaped bracket 310 are symmetrically arranged on both sides of the limiting cross plate 510, and a fixing groove is provided at the top of the slider 520 to maintain plug-in cooperation with the column.

[0028] During specific use, when the limiting cross plate 510 clamps the insulation outer plate 20 and moves it downward for installation, the end block 524 at one end of the slider 520 slides along the inner end of the connecting groove, and the fixed groove opened at the other end moves vertically downward along the column at the corresponding position, so that the two ends of the slider 520 are symmetrically supported and moved downward, thereby improving the stability of the limiting cross plate 510 during the downward movement and avoiding limited downward movement due to uneven force.

[0029] The second object of the present invention is to provide a water purification method for a prestressed steel tube truss thermal insulation exterior wall panel system, comprising the following method steps: S1, placing the entire steel tube truss 10 in the area formed between the top of the bottom support plate 30 and the side surfaces of the two side plates 40, and completing the position correction work of the steel tube truss 10; S2. A gap is reserved between the limiting horizontal plate 510 and the side of the steel tube truss 10, and the innermost insulation outer plate 20 is slid vertically downward along the gap formed by the two side plates 40, sliding downward in accordance with the side of the steel tube truss 10 and passing through the gap. The gap cooperates with the two side plates 40 to form a limiting channel for the vertical sliding of the steel tube truss 10, and the position of the steel tube truss 10 to be installed is corrected; S3, when installing the second insulation outer panel 20, slide the limit horizontal plate 510 horizontally, so that it slides along the sides of the two sliders 520 and re-forms a gap with the sides of the installed insulation outer panel 20; S4, the insulation outer panel 20 to be installed slides along the side of the installed insulation outer panel 20 and passes through the gap, and the limit horizontal plate 510 is loosened. Under the action of the reset component, the limit horizontal plate 510 is attached to the side of the insulation outer panel 20, and pressure is applied to its contact position. The gravity of the insulation outer panel 20 drives the limit horizontal plate 510 and a pair of sliders 520 connected thereto to move vertically downward synchronously until the bottom end of the insulation outer panel 20 contacts the top position of the bottom support plate 30; S5. Slide the limit horizontal plate 510 upwards, driving the slider 520 to move up to the initial position synchronously. The reaction force provided by the reset component to the limit horizontal plate 510 will cause the limit horizontal plate 510 to always fit the side of the insulation outer plate 20, and apply pressure to the side of the insulation outer plate 20, so as to evenly spread the adhesive adhered to the other side of the insulation outer plate 20.
