Description

Technical Field

[0001] The invention belongs to the technical field of walls, and in particular relates to an energy-saving heat-insulating fire-resistant wall and a preparation method thereof. Background Art

[0002] With the development of modern construction technology and the continuous improvement of people's requirements for building performance, walls, as an important part of building structures, are increasingly receiving attention for their energy saving, thermal insulation, fire resistance and installation convenience.

[0003] In traditional wall structures, single materials or simple structural forms are often used. For example, although ordinary brick walls have certain load-bearing and heat-insulating capabilities, their thermal insulation performance is limited. It is difficult to effectively prevent indoor heat loss in winter, and it is also difficult to effectively block outdoor heat input in summer, resulting in high energy consumption of indoor air conditioning and other cooling and heating equipment, which does not meet the requirements of modern building energy conservation. Moreover, the fire resistance of traditional brick walls is also uneven. When a fire occurs, it cannot provide sufficient time guarantee for personnel evacuation and fire rescue, posing a threat to the safety of life and property of indoor personnel.

[0004] On the other hand, some existing thermal insulation walls are insufficient in terms of structural stability. Due to the lack of reasonable frame structure design, they are easily affected by indoor and outdoor environmental factors during long-term use. For example, under the influence of wind pressure generated by air flow and external forces such as collisions between people, the walls may deform, shake or even crack, which not only affects the appearance and service life of the walls, but also may lead to a decrease in thermal insulation and sound insulation performance.

[0005] At the same time, the traditional wall installation method is often fixed and cumbersome, and has poor adaptability to indoor environments of different heights and spatial layouts. During the installation process, if there are problems such as component damage or size mismatch, it is difficult to flexibly adjust or replace, which undoubtedly increases the difficulty and cost of construction, prolongs the construction period, and brings many inconveniences to the smooth progress of the construction project.

[0006] In summary, in order to solve the defects of traditional walls in energy saving, heat preservation, fire resistance, structural stability and installation flexibility, the development of a new type of energy-saving heat-insulating fire-resistant wall has extremely important practical significance and market demand. The energy-saving heat-insulating fire-resistant wall of the present invention is proposed based on the above background, aiming to provide a wall solution with reasonable structure, excellent performance and convenient installation, so as to meet the requirements of modern buildings for various wall performances, improve the overall quality and safety of buildings, reduce energy consumption, and promote the sustainable development of the construction industry.

[0017] A method for preparing an energy-saving heat-insulating refractory wall comprises the following steps: Basic frame construction: Place the integrated structure of the base and the first profile at the preset partition wall position indoors; Installation of the second profile: install two sets of symmetrically arranged and L-shaped second profiles on the first profile to form an inverted T-shaped structure; Inner plate installation: fit the two rectangular plates of the inner plate to the corresponding positions of the L-shaped second profile respectively; Installation of outer panel: fit the lower wall of the outer panel to the bearing structure, fit the inner surface to the second profile and the inner panel, and then fix the outer panel to the second profile, so that the outer panel is closely connected to the inner panel and the frame, and the upper sides of the outer panel, inner panel and second profile are equal in height and have a gap with the indoor ceiling; Installation of the limit plate: Install the limit plate with an inverted U-shaped cross section so that the upper end of the outer plate is clamped in the limit plate; Operation of moving the bearing structure upward: applying an upward force to the bearing structure to make it move upward along the outer side of the first profile, and lifting the outer plate, the inner plate and the second profile upward as a whole; Fixing completed: Continue to move the bearing structure upward until the upper side of the limiting plate is squeezed onto the indoor ceiling.

[0019] 2. Insulation and fire resistance: The setting of the inner and outer panels forms a double-layer wall structure, which plays a good role in insulation. In winter, it can reduce the loss of indoor heat to the outside, and in summer, it can prevent the outdoor heat from entering the room, reducing the energy consumption of indoor air conditioning and other cooling and heating equipment, and achieving energy-saving effects. At the same time, the appropriate selection of inner and outer panel materials can have fire resistance. In the event of an emergency such as a fire, it can prevent the spread of the fire within a certain period of time, buy time for personnel evacuation and fire rescue, and improve the safety of the indoor space.

[0020] 3. Installation flexibility: Each component is installed in steps.

This installation method makes the wall installation process more flexible and can be adjusted according to the actual construction conditions and indoor space conditions. For example, in indoor spaces of different heights, the second profile of the appropriate height can be easily selected for installation. If a problem is found in a component during the installation process, it is also easy to disassemble and replace it separately, reducing the construction difficulty and cost.

[0023] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0024] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 7 As shown, an energy-saving heat-insulating fire-resistant wall provided by an embodiment of the present invention comprises a frame, an inner plate 5 and an outer plate 6, the frame comprises a base 1, a first profile 2 is fixedly connected to the base 1, the cross section of the first profile 2 is U-shaped, two groups of symmetrically arranged second profiles 3 are connected to the upper side of the first profile 2, the second profile 3 is L-shaped, and the two groups of the second profiles 3 form an inverted T-shaped structure, and a lifting and lowering bearing structure 4 is provided on the outer side of the first profile 2; the inner plate 5 is attached to the second profile 3; the lower wall of the outer plate 6 is attached to the bearing structure 4, the inner surface of the outer plate 6 is attached to the second profile 3 and the inner plate 5, and the outer plate 6 is fixedly connected to the second profile 3. The frame further comprises a limit plate 7, the cross section of the limit plate 7 is inverted U-shaped, and the upper end of the outer plate 6 is clamped in the limit plate 7.

[0026] The installation consists of the following stages: Initial stage of installation: First, since the base 1 and the first profile 2 are an integrated structure, when the wall is installed, they are placed as a whole at the preset partition wall position indoors to build a basic frame for the entire wall structure. Next, select a second profile 3 of appropriate height according to actual needs and the height of the indoor space, and install it on the first profile 2. At this time, two groups of symmetrically arranged and L-shaped second profiles 3 form an inverted T-shaped structure, which provides a stable support frame for the subsequent installation of the inner layer plate 5 and the outer layer plate 6. Then, the inner layer plate 5 is installed on the second profile 3, and the two rectangular plates of the inner layer plate 5 are respectively attached to the corresponding positions of the L-shaped second profile 3 to achieve the preliminary construction of the internal structure of the wall. Then install the outer plate 6, the lower wall of the outer plate 6 is attached to the bearing structure 4, the inner surface is attached to the second profile 3 and the inner plate 5, and the outer plate 6 is fixedly connected to the second profile 3, so that the outer plate 6 is closely connected with the inner plate 5 and the frame, and the outer plate 6, the inner plate 5, and the second profile 3 are of the same height and have a gap with the indoor ceiling. Finally, install the limit plate 7, the cross section of the limit plate 7 is an inverted U shape, and the upper end of the outer plate 6 is clamped in the limit plate 7. At this time, the entire wall structure is installed, but it has not yet reached the final installation and fixing state.

[0027] Final fixing stage: Move the bearing structure 4 upwards, and the bearing structure 4 moves upwards along the outer side of the first profile 2. Since the lower wall of the outer plate 6 fits the bearing structure 4, the inner plate 5 fits the second profile 3 and the outer plate 6 is fixed to the second profile 3, the outer plate 6, the inner plate 5 and the second profile 3 will be lifted upwards as a whole during the upward movement of the bearing structure 4. Until the upper side of the limiting plate 7 is squeezed onto the indoor top wall, the entire wall structure is fixed in the vertical direction, and the squeezing of the limiting plate 7 and the indoor top wall and the support of the bearing structure 4 from below keep the wall in a stable installation state in the vertical direction, completing the installation of the energy-saving thermal insulation fire-resistant wall.

[0028] Furthermore, a receiving groove is provided between the two groups of the second profiles 3 , and a U-shaped insert 8 is slidably connected in the receiving groove; a slot 9 is provided on the limiting plate 7 , and the U-shaped insert 8 can be inserted into the slot 9 .

[0029] With the above settings, the specific steps for use are as follows: Initial state and connection preparation: During the wall installation process, after the two sets of second profiles 3 are installed on the first profile 2, the receiving groove formed therebetween can be used to accommodate the U-shaped insert 8. The U-shaped insert 8 can slide upward in the receiving groove to adjust its position. After the outer layer plate 6 is installed and before the stop plate 7 is installed, the U-shaped insert 8 is in a movable state, waiting to be connected to the slot 9 on the lower side of the stop plate 7.

[0030] Connection and fixing stage: When the bearing structure 4 pushes the outer plate 6, the inner plate 5 and the second profile 3 upward until the upper side of the limiting plate 7 is pressed against the indoor ceiling, the U-shaped insert 8 is slid along the receiving groove to be accurately inserted into the slot 9 on the limiting plate 7. In this way, the U-shaped insert 8 connects and fixes the second profile 3 and the limiting plate 7 in the horizontal direction, further enhancing the stability of the entire wall structure in the vertical and horizontal directions.

[0031] Exemplarily, the bearing structure 4 includes a transverse plate 41, a gusset plate 42, and a lifting plate 43; the upper surface of the transverse plate 41 is in contact with the lower side of the outer plate 6; the gusset plate 42 is fixedly connected to the upper side of the outer edge of the transverse plate 41, and the gusset plate 42 is clamped to the lower edge of the outer plate 6; the lifting plate 43 is fixedly connected to the lower side of the inner edge of the transverse plate 41.

[0032] Furthermore, a slot 44 is provided on a side of the transverse plate 41 away from the buckle plate 42 , and the slot 44 is snap-connected to the lower edge of the second profile 3 .

[0033] The installation consists of the following stages: Initial fitting and clamping preparation: During the wall installation process, after the inner and outer panels 5 and 6 are installed on the second profile 3, the bearing structure 4 is installed. First, the upper surface of the horizontal plate 41 is fitted with the lower side of the outer plate 6, so that the horizontal plate 41 is in a position that can bear the weight of the outer plate 6 and related components. At the same time, the clamping groove 44 provided on the side of the horizontal plate 41 away from the gusset plate 42 is clamped to the lower edge of the second profile 3. During the clamping process, the clamping groove 44 is accurately placed on the lower edge of the second profile 3, realizing the initial positioning and connection of the horizontal plate 41 and the second profile 3 in the horizontal direction, laying the foundation for the subsequent overall bearing and fixation.

[0034] Overall fixing stage: The gusset plate 42 is fixedly connected to the upper side of the outer edge of the horizontal plate 41, and the gusset plate 42 is clamped to the lower edge of the outer plate 6. Through the clamping of the gusset plate 42 and the outer plate 6, and the clamping of the horizontal plate 41 and the second profile 3, the horizontal plate 41 can stably bear the weight of the outer plate 6, the inner plate 5 and the second profile 3. The lifting plate 43 is fixedly connected to the lower side of the inner edge of the horizontal plate 41. When the height of the wall needs to be adjusted, the lifting plate 43 is acted on to make the horizontal plate 41 rise or fall together with the outer plate 6, the inner plate 5 and the second profile 3. For example, in the process of lifting the bearing structure 4 upward, the horizontal plate 41 rises along with it. Due to its clamping and fitting relationship with various components, it can ensure the integrity of the entire wall structure until it reaches the predetermined height and the installation is completed.

[0035] Through the above arrangement, the cross plate 41, the gusset plate 42 and the lifting plate 43 of the bearing structure 4 work together to effectively bear the weight of the wall components such as the outer plate 6, the inner plate 5 and the second profile 3. The cross plate 41 is connected to the second profile 3 through the clamping groove 44 and the upper surface is fitted with the outer plate 6 to evenly distribute the weight of each component to prevent the component from being deformed or damaged due to excessive local force. The clamping of the gusset plate 42 to the outer plate 6 further enhances the bearing stability of the cross plate 41 on the outer plate 6, so that the outer plate 6 is reliably supported in the vertical direction. The lifting plate 43 provides the entire bearing structure 4 with a vertical adjustment function. During the wall installation process, it can be conveniently matched with the bearing plate and other components to achieve precise adjustment of the wall height, ensuring that the wall installation meets the design requirements. At the same time, during the use of the wall, it is also conducive to the later maintenance and adjustment of the wall. For example, when the wall height needs to be fine-tuned due to ground subsidence and other reasons, it can be achieved by acting on the lifting plate 43.

[0036] Furthermore, the first profile 2 is provided with a first slide 16, a sliding plate 17 is provided inside the first profile 2, the sliding plate 17 is fixedly connected with a slider 18, the slider 18 is slidably connected to the first slide 16, and the slider 18 is connected to the lifting plate 43; a lifting drive mechanism is provided in the first profile 2, and the lifting drive mechanism is attached to the lower surface of the sliding plate 17.

[0037] With this arrangement, the lifting drive mechanism first moves the sliding plate 17 upwards so that the U-shaped insert 8 can be inserted into the slot 9, and then the sliding plate 17 continues to rise, thereby driving the bearing structure 4 to rise. The lifting drive mechanism can be arranged as required, such as a screw, the lower end of which is rotatably connected to the first profile 2 through a bearing, and the screw is connected to the sliding plate 17 through a screw sleeve.

[0038] Furthermore, each group of the second profiles 3 includes two symmetrically arranged parts with a gap between the two parts; a positioning piece 19 is fixedly connected to the middle of the side wall edge of the inner layer plate 5, and the positioning piece 19 is inserted into the gap. Through this arrangement, the inner layer plate 5 can be positioned for accurate installation.

[0039] In one embodiment, the slider 18 is fixedly connected to the lifting plate 43 .

[0040] In another embodiment, the connection between the slider 18 and the lifting plate 43 is as follows: The lifting plate 43 is provided with a second slideway 20, and the lower side of the outer surface of the lifting plate 43 is provided with an inclined surface. The slider 18 is slidably connected to the second slideway 20, and the slider 18 is rotatably connected with a roller 21, and the roller 21 is rollingly connected to the inclined surface; the roller 21 is provided with a first positioning hole, and the inclined surface is provided with a second positioning hole, and the first positioning hole and the second positioning hole are fixed by a connecting member 22 (such as a screw).

[0041] When in use, the rise of the supporting structure 4 has two stages: In the first stage, the first positioning hole and the second positioning hole are fixed by a connecting member 22 (such as a screw). At this time, the slider 18 can drive the lifting plate 43 to rise synchronously through the roller 21 until the outer plate 6, the inner plate 5, and the second profile 3 reach the preset position; In the second stage, the connecting members 22 (such as screws) in the first positioning hole and the second positioning hole are removed. At this time, when the slider 18 continues to move upward, the roller 21 can roll along the inclined surface, so that the entire bearing structure 4 is close to each other. In this way, the outer plate 6 is clamped, and the two parts of the second profile 3 are also clamped. Finally, the first positioning hole and the second positioning hole are fixed by screws.

[0042] Specifically, the inner wall of the receiving groove is fitted with a connecting plate 10, and sealing strips 11 are clamped on both sides of the connecting plate 10, and the sealing strips 11 are fitted to the second profile 3. A U-shaped convex plate 12 is provided in the middle of the connecting plate 10, and a strip convex strip 13 is provided on the inner surface of the U-shaped convex plate 12. A groove 14 is provided at the position where the two groups of the second profiles 3 are close to each other, and a U-shaped clamping strip 15 is clamped inside the groove 14. The outer layer plate 6 is fitted to the U-shaped clamping strip 15, and the outer layer plate 6, the U-shaped clamping strip 15 and the connecting plate 10 are fixedly connected by screws.

[0043] A method for preparing an energy-saving heat-insulating refractory wall comprises the following steps: Basic framework construction: The integrated structure of the base 1 and the first profile 2 is placed at a preset partition wall position indoors, ensuring that it is placed stably and accurately, thereby constructing a basic framework of the entire wall structure.

[0044] Second profile installation: According to the actual indoor space height and design requirements, the second profile 3 of appropriate height is selected.

[0045] Two sets of symmetrically arranged and L-shaped second profiles 3 are installed on the first profile 2 to form an inverted T-shaped structure, providing a stable support frame for the subsequent installation of the inner layer plate 5 and the outer layer plate 6, and ensuring a firm connection during installation.

[0046] Inner board installation: The two rectangular plates of the inner layer plate 5 are respectively fitted to the corresponding positions of the L-shaped second profile 3 to realize the preliminary construction of the internal structure of the wall, ensuring a tight fit without gaps.

[0047] Outer panel installation: The lower wall of the outer panel 6 is fitted on the bearing structure 4, and the inner surface is fitted on the second profile 3 and the inner panel 5. Then the outer panel 6 is fixedly connected to the second profile 3, so that the outer panel 6 is tightly connected to the inner panel 5 and the frame, and it is necessary to ensure that the outer panel 6, the inner panel 5, and the second profile 3 are of the same height and have a gap reserved with the indoor ceiling wall.

[0048] Installation of the limiting plate: Install the limiting plate 7 with an inverted U-shaped cross section so that the upper end of the outer plate 6 is clamped in the limiting plate 7. At this time, the entire wall structure is installed, but has not yet reached the final installation and fixing state.

[0049] Operation of moving the bearing structure upward: an upward force is applied to the bearing structure 4 to make it move upward along the outer side of the first profile 2. Since the lower wall of the outer plate 6 fits the bearing structure 4, the inner plate 5 fits the second profile 3 and the outer plate 6 is fixed to the second profile 3, when the bearing structure 4 moves upward, the outer plate 6, the inner plate 5 and the second profile 3 are lifted upward as a whole.

[0050] Fixing completed: Continue to move the bearing structure 4 upward until the upper side of the limiting plate 7 is squeezed onto the indoor ceiling. At this time, the entire wall structure is fixed in the vertical direction, and the wall is kept in a stable installation state in the vertical direction through the squeezing of the limiting plate 7 and the indoor ceiling and the support of the bearing structure 4 from below, thereby completing the preparation of the energy-saving thermal insulation and fire-resistant wall.

[0051] Working principle of the present invention: When in use, first, since the base 1 and the first profile 2 are an integrated structure, when the wall is installed, it is placed as a whole at the preset partition wall position indoors to build a basic frame for the entire wall structure. Then, according to actual needs and the height of the indoor space, a second profile 3 of appropriate height is selected and installed on the first profile 2. At this time, two groups of symmetrically arranged and L-shaped second profiles 3 form an inverted T-shaped structure, which provides a stable support frame for the subsequent installation of the inner layer plate 5 and the outer layer plate 6. Then, the inner layer plate 5 is installed on the second profile 3, and the two rectangular plates of the inner layer plate 5 are respectively fitted to the corresponding positions of the L-shaped second profile 3 to achieve the preliminary construction of the internal structure of the wall. Then install the outer plate 6. The lower wall of the outer plate 6 fits on the bearing structure 4, and the inner surface fits the second profile 3 and the inner plate 5. The outer plate 6 is fixedly connected to the second profile 3, so that the outer plate 6 is closely connected to the inner plate 5 and the frame. At the same time, the outer plate 6, the inner plate 5, and the second profile 3 are of the same height and have a gap with the indoor ceiling. Finally, install the limit plate 7. The cross-section of the limit plate 7 is an inverted U shape. The upper end of the outer plate 6 is clamped in the limit plate 7. At this time, the entire wall structure is installed, but it has not yet reached the final installation and fixing state. Move the bearing structure 4 upward. The bearing structure 4 moves upward along the outer side of the first profile 2. Since the lower wall of the outer plate 6 fits the bearing structure 4, the inner plate 5 fits the second profile 3 and the outer plate 6 is fixed to the second profile 3, the outer plate 6, the inner plate 5, and the second profile 3 will be lifted upward as a whole during the upward movement of the bearing structure 4. Until the upper side of the limiting plate 7 is squeezed onto the indoor ceiling wall, the entire wall structure is fixed in the vertical direction. The wall is kept in a stable installation state in the vertical direction through the squeezing of the limiting plate 7 and the indoor ceiling wall and the support of the bearing structure 4 from below, thus completing the installation of the energy-saving thermal insulation and fire-resistant wall.
