Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a method for supporting composite wall panels for passive windows. Background Technology

[0002] With the development of building technology, windows, as an important component of buildings, not only fulfill the basic functions of lighting and ventilation, but also play a vital role in building aesthetics, energy efficiency, and safety. The structural stability and safety of windows, especially window sills, are crucial in the design process.

[0003] Generally, most residential buildings are frame structures with windows on all four sides (east, south, west, and north). There are no full-height walls to secure the window frames; they are only fixed by the upper structural beams and the bottom composite wall panels. This results in relatively weak support for the window sills and lower safety. Furthermore, many existing building designs use passive windows, which have special frame and glass materials, and are large in area, making them significantly heavier than ordinary windows. When placed on composite insulated wall panels, under their own weight and prolonged wind loads, there is a risk of the wall panels undergoing compressive deformation, and there is also a risk of gaps appearing between the window frames and the upper and lower structural elements. Summary of the Invention

[0004] The purpose of this invention is to provide a method for supporting composite wall panels for passive windows, so as to solve the technical problem of poor load-bearing capacity of the supporting wall panels for passive windows in the prior art.

[0005] Based on the above concept, the technical solution adopted by this invention is as follows:

[0006] A method for supporting composite wall panels for passive windows, comprising:

[0007] Step 1: A positioning groove is made in the support plate, and the positioning groove passes through the support plate along the height direction of the support plate;

[0008] Step 2: Insert the reinforcing column into the positioning groove, with the top of the reinforcing column abutting against the windowsill and the bottom of the reinforcing column abutting against the floor slab;

[0009] Step 3: Set up templates on both sides of the support plate, and multiple templates together form an installation space;

[0010] Step 4: Pour concrete into the installation space;

[0011] Step 5: After the concrete has solidified, remove the formwork. The solidified concrete forms a supporting wall, and an installation end face is formed on the top of the supporting wall. A passive window is installed on the installation end face.

[0012] The positioning groove is located on the indoor side of the support plate, and the depth of the positioning groove is less than the thickness of the reinforcing column. In step 2, part of the reinforcing column protrudes from the positioning groove along the thickness direction.

[0013] The process between step 2 and step 3 includes:

[0014] Step 21: A reinforcing rib is provided on the support plate. The reinforcing rib connects the two sides of the positioning groove, and the inner wall of the reinforcing rib abuts against the protruding part of the reinforcing column.

[0015] Step 22: Lock the reinforcing column and the reinforcing rib with locking devices.

[0016] The reinforcing bars include longitudinal reinforcing bars and transverse reinforcing bars. The longitudinal reinforcing bars are connected to the support plate and abut against the side wall of the reinforcing column, and the transverse reinforcing bars are connected to the support plate and abut against the top wall of the reinforcing column.

[0017] The step between step 2 and step 3 includes:

[0018] Step 21: Install fixing ribs at the bottom of the reinforcing column;

[0019] Step 22: Lock the reinforcing column and the fixing rib with the locking device.

[0020] Step 3 includes:

[0021] Step 31: Directly erect the formwork on the outdoor side of the support plate;

[0022] Step 32: On the side of the support plate located indoors, an auxiliary plate is installed on the support plate so that the auxiliary plate is flush with the reinforcing column in the first plane;

[0023] Step 33: Install templates on the reinforcing column and the auxiliary plate.

[0024] Step 31 includes: first, setting multiple buffer pads on the support plate, and then supporting the template on the support plate.

[0025] In step 5, the installation of the passive window includes: first, reinforcing the window frame of the passive window to the installation end face with fasteners, and then applying thermal insulation mortar to the installation end face.

[0026] In step 5, the installation of the passive window includes: attaching a waterproof and breathable membrane to the outside of the passive window and attaching an air-tight membrane to the inside of the passive window.

[0027] The method further includes the following after step 5:

[0028] Step 6: Install a first protective layer on the outdoor supporting wall and a second protective layer on the indoor supporting wall.

[0029] The beneficial effects of this invention are:

[0030] The composite wall panel support method for passive windows proposed in this invention involves first creating positioning grooves on a support plate, extending along the height of the support plate. Reinforcing columns are then inserted into these grooves, with their tops abutting against the window sill cap and their bottoms against the floor slab. After the reinforcing columns are installed, templates are erected on both sides of the support plate, with multiple templates forming an installation space. Concrete is then poured into this installation space. After the concrete has solidified, the templates are removed, and the solidified concrete forms a support wall. The top of the support wall has an installation end face, on which the passive window is installed. The multiple reinforcing columns at the bottom of the window sill cap support the passive window, improving the load-bearing capacity of the support wall and resulting in better stability.

[0052] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0053] See Figures 1 to 9 The composite wall panel support method for passive windows provided in this embodiment of the invention includes: Step 1: A positioning groove 11 is opened on the support plate 10, and the positioning groove 11 penetrates the support plate 10 along the height direction of the support plate 10; Step 2: A reinforcing column 20 is snapped into the positioning groove 11, the top end of the reinforcing column 20 abuts against the window sill cap 102, and the bottom end of the reinforcing column 20 abuts against the floor slab 103; Step 3: Templates 50 are erected on both sides of the support plate 10, and multiple templates 50 together form an installation space; Step 4: Concrete is poured in the installation space; Step 5: After the concrete has solidified, the templates 50 are removed, and the solidified concrete forms a support wall 30. An installation end face 31 is formed on the top of the support wall 30, and the passive window 101 is installed on the installation end face 31. The passive window 101 is supported by multiple reinforcing columns 20 set at the bottom of the window sill cap 102, which improves the load-bearing capacity of the support wall 30 for the window sill cap 102 and has better stability.

[0054] See Figure 1 In this embodiment, the passive window 101 is applicable to scenarios where many people gather, such as hospitals, teaching buildings, and residences. To improve the comfort of the building, the exterior wall of the passive window 101 is designed with thermal insulation properties. Therefore, in this embodiment, the support plate 10 is made of thermal insulation composite board, and an insulation layer 12 is provided on the inner side of the support plate 10. Generally, thermal insulation foam is used. Perlite board 13 is wrapped around the outer periphery of the insulation layer 12. The perlite board 13 can effectively reduce heat exchange between the inside and outside of the building and reduce the energy consumption of the heating equipment. To improve the stability of the support plate 10, multiple limiting rods 14 are provided on the support plate 10. The multiple limiting rods 14 are arranged along the height direction on the support plate 10, and the two ends of the limiting rods 14 are respectively connected to the perlite boards 13 on both sides, thereby achieving a fixing effect and preventing the perlite boards 13 from falling off, thus providing better stability.

[0055] Furthermore, because different materials have different coefficients of thermal expansion, the support plate 10 is prone to cracks at the joints after plastering. Therefore, in this embodiment, a layer of wire mesh 15 is provided on the outer surface of the support plate 10. Adding a layer of wire mesh 15 allows the perlite board 13, the limiting rod 14 and other materials constituting the support plate 10 to form a whole under the constraint of the wire mesh 15, which is not easy to crack, thereby making the support plate 10 have better crack resistance and waterproofness.

[0056] See Figures 2 to 4 To facilitate the installation of the reinforcing column 20 and improve its stability after installation, a positioning groove 11 is provided on the support plate 10 for installing the reinforcing column 20. In this embodiment, a notch of the appropriate size is cut into the surface of the support plate 10 by gas cutting, thereby forming the positioning groove 11. In some embodiments, wire saw cutting or laser cutting methods may also be used.

[0057] For ease of construction, in this embodiment, the positioning groove 11 is located on the indoor side of the support plate 10, and the depth of the positioning groove 11 is less than the thickness of the reinforcing column 20. In step 2, a portion of the reinforcing column 20 protrudes from the positioning groove 11 along its thickness direction. The fact that the depth of the positioning groove 11 is less than the thickness of the reinforcing column 20 means that after the reinforcing column 20 is embedded in the positioning groove 11, a portion of the reinforcing column 20 protrudes from the positioning groove 11 along its thickness direction. This results in a larger supporting area for the top of the reinforcing column 20 against the windowsill cap 102, thereby improving the load-bearing capacity of the windowsill cap 102.

[0058] See Figure 5 and Figure 6 To improve the stability of the reinforcing column 20, the following is also included between step 2 and step 3:

[0059] Step 21: Install fixing ribs 41 at the bottom of the reinforcing column 20;

[0060] Step 22: Lock the reinforcing column 20 and the fixing rib 41 by locking the locking member 44.

[0061] The reinforcement effect of the reinforcing column 20 can be improved by fixing the ribs 41, preventing the reinforcing column 20 from tilting or even shifting, which would affect the support effect. After the fixing ribs 41 are installed, the reinforcing column 20 and the fixing ribs 41 are locked with locking devices 44, thereby further improving stability and preventing the fixing ribs 41 from falling off. In this embodiment, all fixing ribs 41 are set inside the wire mesh 15 of the support plate 10, thereby optimizing space utilization and avoiding interference with other construction operations outside the support plate 10. In this embodiment, the locking device 44 is made of binding wire, which is readily available and flexible to operate. The fixing ribs 41 at the bottom and the wire mesh 15 are firmly tied with binding wire. For better stability, the binding wire is tied with no less than two knots.

[0062] In addition, the upper part of the reinforcing column 20 needs to be fixed to the support plate 10 to improve stability. Therefore, the process between step 2 and step 3 also includes:

[0063] Step 21: Set reinforcing ribs on the support plate 10. The reinforcing ribs connect the two sides of the positioning groove 11, and the inner wall of the reinforcing ribs abuts against the protruding part of the reinforcing column 20.

[0064] Step 22: Secure the reinforcing column 20 and the reinforcing rib with locking device 44.

[0065] Because the support plate 10 has a positioning groove 11 for engaging the reinforcing column 20, a reinforcing rib is provided on the support plate 10. The reinforcing rib connects both sides of the positioning groove 11, and the inner wall of the reinforcing rib abuts against the protruding part of the reinforcing column 20. Thus, the reinforcing rib connects to both sides of the positioning groove 11, effectively limiting the reinforcing column 20 and preventing it from falling out of the positioning groove 11, resulting in better stability. The reinforcing column 20 and the reinforcing rib are locked together by the locking member 44 to prevent the reinforcing rib from falling off. In this embodiment, the locking member 44 is a tie wire. In some embodiments, steel wire, metal straps, etc., may also be used.

[0066] Because a notch needs to be cut in the support plate 10 to form the positioning groove 11, the wire mesh 15 on the support plate 10 may break due to the cutting. To improve stability, the reinforcing ribs include longitudinal reinforcing ribs 42 and transverse reinforcing ribs 43. The longitudinal reinforcing ribs 42 connect to the support plate 10 and abut against the side wall of the reinforcing column 20, while the transverse reinforcing ribs 43 connect to the support plate 10 and abut against the top wall of the reinforcing column 20. By connecting the longitudinal reinforcing ribs 42 and transverse reinforcing ribs 43 with the wire mesh 15, the support plate 10 and the reinforcing column 20 form a whole, which can improve stability and have a stronger load-bearing capacity.

[0067] See Figure 7 and Figure 8 After the support plate 10 and reinforcing column 20 are fixed, formwork 50 needs to be erected for pouring concrete. Step 3 includes:

[0068] Step 31: Directly erect the formwork 50 on the outdoor side of the support plate 10;

[0069] Step 32: On the side of the support plate 10 located indoors, an auxiliary plate 52 is installed on the support plate 10, so that the auxiliary plate 52 is flush with the reinforcing column 20 in the first plane;

[0070] Step 33: Erect formwork 50 on the reinforcing column 20 and auxiliary plate 52.

[0071] Since the outdoor side of the support plate 10 is uncut, it will not interfere with the template 50. Therefore, the template 50 can be directly erected and connected to the wire mesh 15 of the support plate 10, resulting in high installation efficiency. On the indoor side of the support plate 10, a positioning groove 11 is formed by a cut notch, and the reinforcing column 20 protrudes from the positioning groove 11, making the surface of the indoor side of the support plate 10 uneven. To improve the stability of the template 50 during erection and prevent the template 50 from shaking due to the protrusion of the reinforcing column 20, an auxiliary plate 52 is set on the support plate 10, making the auxiliary plate 52 flush with the reinforcing column 20 in the first plane, thereby improving stability. After the auxiliary plate 52 is laid, the template 50 is erected on the reinforcing column 20 and the auxiliary plate 52. In this embodiment, the auxiliary plate 52 is made of wood or steel pipe, which has high strength, a flat cross-section, and can be reused multiple times.

[0072] Specifically, step 31 includes: first, setting multiple buffer blocks 51 on the support plate 10, and then supporting the formwork 50 on the support plate 10. Generally, the gap between the wire mesh 15 and the formwork 50 on the outdoor side of the support plate 10 is 1cm. To prevent the formwork 50 from deforming during the reinforcement process, the buffer blocks 51 can reduce the impact on the formwork 50 and prevent the formwork 50 from shifting or deforming vertically during construction, thus affecting the support effect. At the same time, the multiple buffer blocks 51 can, to a certain extent, seal the gaps on the vertical surface of the formwork 50 to prevent concrete leakage.

[0073] Furthermore, to enhance the overall stability of the structure and improve the load-bearing capacity of the formwork 50, tie rods are used to reinforce both sides of the formwork 50. Tie rods 60 are inserted through both sides of the formwork 50, and the ends of the tie rods 60 are locked with U-shaped clips 61, thereby reinforcing the formwork 50 and improving its stability under load.

[0074] After the formwork 50 is stably erected, multiple formwork 50s are used together to form an installation space. First, the interior of the installation space is cleaned to ensure there are no debris or residues. The concrete is mixed strictly according to the design specifications to ensure uniform mixing without lumps or segregation. After mixing, the concrete is poured gradually, avoiding large amounts of concrete being poured at once to prevent displacement or damage to the formwork 50. The height of the poured concrete is controlled to prevent segregation. To improve concrete quality, a vibrator is used to compact the concrete, removing air bubbles and ensuring density. The effects of ambient temperature and humidity on concrete curing are considered, ensuring the concrete reaches sufficient strength before removing the formwork 50. The concrete then solidifies to form a supporting wall 30, with an installation end face 31 at the top. A passive window 101 is installed on the installation end face 31.

[0075] See Figure 9 Regarding the installation process of the passive window 101, specifically, in step 5, the installation of the passive window 101 includes: firstly, reinforcing the window frame of the passive window 101 to the mounting end face 31 using fasteners 74, and then applying thermal insulation mortar 73 to the mounting end face 31. Connecting the window frame of the passive window 101 to the mounting end face 31 using fasteners 74 significantly enhances the stability of the window frame on the supporting wall 30, ensuring that the passive window 101 is not easily loosened or deformed during long-term use. In this embodiment, expansion bolts are selected as the fasteners 74 to reinforce the window frame. Applying thermal insulation mortar 73 to the mounting end face 31 helps improve the overall building's energy efficiency. It further reduces heat leakage through the window frame, better maintains indoor temperature stability, reduces the infiltration of hot and cold air, and thus improves living comfort.

[0076] To improve the waterproofing performance of the passive window 101, step 5 includes the following steps during installation: applying a waterproof and breathable membrane to the outside of the passive window 101 and applying an air-barrier membrane to the inside of the passive window 101. The waterproof and breathable membrane applied to the outside of the passive window 101 prevents rainwater and external moisture from seeping into the building, thus protecting the window frame and walls from moisture. Simultaneously, the breathability ensures that moisture inside the walls can escape, preventing condensation. The air-barrier membrane applied to the inside of the passive window 101 helps prevent indoor heating or cooling from leaking to the outside, better maintaining indoor temperature stability.

[0077] After the passive window 101 is installed, the wall surface of the supporting wall 30 needs to be decorated, which includes the following after step 5:

[0078] Step 6: Install a first protective layer 71 on the outdoor supporting wall 30 and a second protective layer 72 on the indoor supporting wall 30.

[0079] Since the humidity and temperature environments faced by the wall are different when it is located indoors and outdoors, different protective layers are selected. In this embodiment, the first protective layer 71 is sprayed with heat-insulating and anti-corrosion materials to improve the durability and heat insulation of the supporting wall 30; the second protective layer 72 is made of protective materials such as ceramic tiles, which is both aesthetically pleasing and can protect the supporting wall 30.

[0080] The above embodiments merely illustrate the basic principles and characteristics of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
