Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a prefabricated wind-resistant, earthquake-resistant, and energy-saving exterior window structure and its construction method. Background Technology

[0002] In the field of building construction, the structural strength of the bottom frame of an exterior window and the reliability of the connection between the window body and the bottom frame are the core factors that determine the overall stability of the exterior window installation and its safe use.

[0003] Traditional exterior windows often use a single flat frame structure at the bottom, which is insufficient in terms of bending and shear strength. Furthermore, the window body is only connected to the bottom frame by a simple sliding rail connection, lacking effective limiting and fastening structures. After installation, the window body is prone to loosening and displacement. At the same time, traditional exterior windows do not have a reasonable drainage and diversion structure at the bottom, and rainwater can easily accumulate in the gaps at the bottom of the window frame. Long-term soaking will corrode the bottom frame and connection parts, further weakening the structural strength. When subjected to external forces such as strong winds and earthquakes, the window body is prone to violent shaking or even falling off the frame, posing a significant threat to the safety of people and property inside the building. Summary of the Invention

[0004] To overcome the above shortcomings, this invention provides a prefabricated wind-resistant, earthquake-resistant, and energy-saving exterior window structure and its construction method, solving the core technical problems of low strength of the bottom frame structure of traditional exterior windows, unstable connection between the window body and the bottom, and poor drainage at the bottom leading to structural corrosion and detachment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a prefabricated wind-resistant, earthquake-resistant, and energy-saving exterior window structure, characterized in that it includes a bottom frame, a top frame, two side frames, and two window bodies; the bottom frame, top frame, and two side frames are connected end to end to form a U-shaped exterior window main frame;

[0006] The bottom frame includes an outer protective plate and an inner protective plate arranged in parallel. The height of the outer protective plate is lower than that of the inner protective plate. A drainage ramp is fixedly connected between the outer and inner protective plates. A reinforcing plate is fixedly connected between the side of the inner protective plate facing the outer protective plate and the bottom of the drainage ramp. Two support rails are fixedly connected to the top of the drainage ramp. Multiple through drainage holes are evenly opened along the length of the bottom sidewall of the support rails. The window body is fitted with glass. A sliding groove is opened at the bottom of the window body to slide and engage with the support rails.

[0007] The drainage ramp is used to guide rainwater to the drainage hole at the bottom of the support rail for discharge. The reinforcing plate is used to enhance the structural strength of the bottom frame to improve the overall wind and earthquake resistance of the exterior window. The snap-fit ​​structure between the sliding groove and the support rail is used to ensure the stability of the window body installation.

[0008] Furthermore, it also includes two central outer window frames and two side outer window frames. The two side outer window frames are respectively set on both sides of the two central outer window frames. The two central outer window frames are detachably connected by a connecting component. Multiple insert rods are fixedly connected to the side of the two central outer window frames that are far apart from each other. The side outer window frames facing the central outer window frames have slots that correspond to and engage with the insert rods.

[0009] Furthermore, the connecting assembly includes multiple first sliding sleeves, and multiple sliding rods are fixedly connected to the sides of the two middle outer window frames that are close to each other. The sliding rods slide through the interior of the corresponding first sliding sleeves. Connecting rods are fixedly connected to one side of the two first sliding sleeves located below and close to the outside. The other end of the connecting rod is slidably fitted with a second sliding sleeve. A strip plate is fixedly connected to the end of the second sliding sleeve away from the first sliding sleeve. A strip groove is opened on the side wall of the first sliding sleeve to engage with the strip plate. A through threaded hole is opened on the first sliding sleeve. A threaded groove is opened on the strip plate that is coaxial with the threaded hole.

[0010] Furthermore, the number of the insertion rods and the slots are equal and their positions correspond one-to-one, and the outer wall of the insertion rod is sealed and fitted to the inner wall of the slot.

[0011] Furthermore, it also includes at least two first fixing plates and multiple second fixing plates; a placement plate is fixedly connected to one side of the first fixing plate, and the top of the placement plate is provided with a placement arc groove that matches the shape of the first sliding sleeve. The placement arc groove is used to support and axially position the first sliding sleeve.

[0012] A support plate for supporting the side window frame is fixedly connected to one side of the second fixing plate. A positioning circular groove is opened on one side inner wall of the support plate, a positioning rectangular groove is opened on one side bottom inner wall of the support plate, and a T-shaped groove is opened on the side wall of the support plate.

[0013] Furthermore, it also includes a plurality of limiting blocks corresponding one-to-one with the support plate. One end of the limiting block is fixedly connected to a positioning rod that engages with the positioning circular groove, one side of the limiting block is fixedly connected to a T-shaped block that engages with the T-shaped groove, and the bottom of the limiting block is fixedly connected to a positioning rectangular plate that engages with the positioning rectangular groove.

[0014] Furthermore, the curvature of the arc-shaped groove is consistent with the outer circumferential curvature of the first sliding sleeve, and the depth of the arc-shaped groove is not less than 1 / 3 of the diameter of the first sliding sleeve.

[0015] Furthermore, the limiting block and the support plate are fixedly connected by fastening screws, which pass through the limiting block and are screwed into the preset threaded hole of the support plate.

[0016] Furthermore, both the first fixing plate and the second fixing plate are fixedly installed on the outer side of the building wall at a predetermined position using expansion bolts.

[0017] A construction method for a prefabricated wind-resistant, earthquake-resistant, and energy-saving exterior window structure includes the following steps:

[0018] Step S1: Place the prefabricated bottom frame and top frame between two parallel side frames, fix the two side frames to the preset installation position on the building wall, adjust the external protective plate and top frame to the preset height, and then fix them to the side frames and the building wall respectively to complete the installation of the internal window frame.

[0019] Step S2: On the outside of the building wall, at the position corresponding to the installation of the exterior window, fix the first fixing plate and the second fixing plate respectively using expansion bolts;

[0020] Step S3: Place the two ends of the two side window frames inside the support plates of the corresponding second fixed plates to complete the initial positioning of the side window frames; push the limiting block laterally into the support plate so that the positioning rod engages with the positioning round groove, the T-block engages with the T-groove, and the positioning rectangular plate engages with the positioning rectangular groove; then fix the limiting block to the support plate with the fastening screws.

[0021] Step S4: Insert the sliding rods of the two middle outer window frames into the interior of the corresponding first sliding sleeves, and place the first sliding sleeves in the placement arc groove of the first fixed plate; push the two middle outer window frames to both sides so that the insert rods on the middle outer window frames are fully engaged with the slots on the side outer window frames; slide the second sliding sleeve to drive the strip plate into the strip groove of the first sliding sleeve and place it between the two sliding rods; then pass the connecting screws through the threaded hole of the first sliding sleeve, the threaded groove of the strip plate, and the bottom inner wall of the placement arc groove in sequence to complete the fixed connection between the strip plate, the placement plate, and the first sliding sleeve.

[0022] Step S5: Push the window body upward into the internal groove of the top frame, then move the window body downward so that the sliding groove at the bottom of the window body slides and engages with the support rail at the top of the drainage slope, thus completing the overall installation of the prefabricated wind-resistant, earthquake-resistant, and energy-saving exterior window structure.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. In this invention, the bottom frame, through a composite structure of an external protective plate, an internal protective plate, a drainage ramp, and a reinforcing plate, significantly improves the bending and shear strength of the bottom frame; the window body adopts an embedded sliding snap connection between the sliding groove and the support rail, replacing the traditional simple overlapping method, realizing multi-directional limiting of the window body and solving the problem of loose and wobbling bottom connection; the coordinated design of the drainage ramp and the drainage hole at the bottom of the support rail can quickly drain the water accumulated at the bottom, avoid long-term immersion of rainwater and corrosion of the bottom structure, extend the stability of the external window, and reduce the risk of the window falling off under strong winds and earthquakes.

[0025] 2. In this invention, the interlocking of the central outer window frame and the side outer window frame, the cooperation of the sliding rod and the sliding sleeve, and the anti-retraction limit of the strip plate make the various components of the outer window form a rigid connection, which can evenly distribute the external load and further enhance the overall wind and earthquake resistance. The standardized positioning structure enables the rapid alignment of each component, and the installation can be completed on site with only interlocking and screw fixing. There is no need for complicated welding procedures, which reduces the construction difficulty while ensuring installation accuracy. Attached Figure Description

[0034] Example 1

[0035] Reference Figure 1-7 This embodiment provides a prefabricated wind-resistant, earthquake-resistant, and energy-saving exterior window structure, including a bottom frame, a top frame 4, two side frames 7, two window bodies 3, two central exterior window frames 6, two side exterior window frames 5, at least two first fixing plates 13, multiple second fixing plates 14, and matching limiting connectors; the bottom frame, top frame 4, and two side frames 7 are connected end to end to form a U-shaped closed internal main frame, which serves as the load-bearing foundation for the window body; the two central exterior window frames 6 and the two side exterior window frames 5 are spliced ​​together to form an external reinforced protective frame, which together with the internal main frame constitutes a double-layer load-bearing system; the first fixing plates 13 and second fixing plates 14 are rigidly anchored to the building wall by expansion bolts to achieve a reliable connection between the exterior window and the wall.

[0036] like Figure 3 As shown, the bottom frame adopts a composite structure with double protective plates, sloping drainage, and triangular reinforcement:

[0037] The outer protective plate 1 and the inner protective plate 9 are set in parallel. The height of the outer protective plate 1 is 20-30mm lower than that of the inner protective plate 9, forming an outer water barrier to prevent rainwater from flowing back into the room. A drainage slope 12 is welded between the outer protective plate 1 and the inner protective plate 9. The drainage slope 12 is inclined to the outside with a slope controlled at 3%-5% to ensure that rainwater is quickly guided to the outside under the action of gravity.

[0038] A triangular reinforcing plate 10 is welded between the side of the internal protective plate 9 facing the external protective plate 1 and the bottom of the drainage inclined plate 12 to form a triangular stable force-bearing structure, which can increase the bending and shear strength of the bottom frame by more than 40% and resist strong wind negative wind pressure and earthquake horizontal shear force.

[0039] like Figure 3As shown, two parallel support rails 11 are welded to the top of the drainage inclined plate 12. The support rails 11 are made of 6063-T5 aluminum alloy profiles and the surface is treated with anodized anti-corrosion. The bottom side wall of the support rails 11 has through drainage holes with a diameter of 8-10mm at equal intervals along the length direction, with a hole spacing of 150-200mm. The two ends of the outer protective plate 1 are also provided with drainage holes for draining the water flowing down from the drainage inclined plate 12, forming a cooperative drainage system with the drainage inclined plate 12 to prevent rainwater from accumulating in the rails and corroding the structure.

[0040] The window body 3 is made of thermally broken aluminum profile and is internally fitted with double-layer hollow Low-E glass 2. The window body 3 and the frame adopt a double embedded limiting design: the bottom of the window body 3 has a sliding groove 8 that matches the support rail 11. The depth of the sliding groove 8 is not less than 2 / 3 of the height of the support rail 11. The embedded sliding snap-fit ​​replaces the traditional simple overlap, realizing multi-directional limiting of the window body in the left, right and front and back directions, preventing lateral displacement and vertical jumping under strong winds. The bottom of the top frame 4 has a groove with a depth of 15-20mm, which precisely matches the top contour of the window body 3. During installation, the top of the window body is embedded in the groove and the bottom is snapped into the rail, forming a double constraint at the top and bottom, further improving the stability of the connection.

[0041] like Figure 4 , Figure 6 , Figure 7 As shown, the two central outer window frames 6 are detachably connected by a connecting component, and the central outer window frame 6 and the side outer window frame 5 are engaged by a plug-in slot structure to form an overall load-bearing external reinforcing frame.

[0042] Cylindrical inserts 23 are welded to the two central outer window frames 6 on their opposite sides. The inserts are 20-25mm in diameter and 50-60mm in length. Slots 34 corresponding to the inserts are opened on the side of the side outer window frame 5 facing the central outer window frame. A 3mm thick EPDM rubber sealing gasket is pasted on the inner wall of the slot. After the insert is inserted, it fits tightly with the sealing gasket, which not only ensures the connection is sealed, but also buffers the impact of external forces. The insertion depth of the insert is not less than 40mm to ensure the connection strength.

[0043] On the side of the two middle outer window frames 6 that are close to each other, a sliding rod 24 is welded. The sliding rod slides through the corresponding first sliding sleeve 25. The sleeve length is 150-200mm. The extension length of the sliding rod can be adjusted according to the actual width of the outer window to fit an outer window opening with a width of 1200mm-2400mm.

[0044] Two first sliding sleeves 25 located at the bottom and near the outside are welded with connecting rods 26 on their side walls. The other end of the connecting rods 26 is slidably fitted with a second sliding sleeve 31. A strip plate 32 is welded to the end of the second sliding sleeve 31. A strip groove 33 matching the strip plate 32 is opened on the side wall of the first sliding sleeve 25. After the strip plate 32 is inserted, it is located between the two sliding rods 24, which can effectively prevent the sliding rods 24 from retracting to the middle and prevent the middle outer window frame 6 from separating from the side outer window frame 5. Coaxial M8 threaded holes 29 and threaded grooves 30 are opened on the first sliding sleeves 25 and the strip plate 32, respectively. They are fixed by connecting screws, and the screws pass through the bottom of the placement plate 28 to achieve a rigid connection between the sleeve and the wall.

[0045] like Figure 5 As shown, both the first fixing plate 13 and the second fixing plate 14 are made of Q235 hot-dip galvanized steel sheet with a thickness of 5-8mm. They are fixed to the outside of the building wall with M10 expansion bolts. The expansion bolts are embedded in the wall to a depth of not less than 100mm to ensure anchoring strength.

[0046] A placement plate 28 is welded to one side of the first fixed plate 13. An arc-shaped groove 27 is opened on the top of the placement plate 28. The curvature of the arc-shaped groove 27 is consistent with the outer circumferential curvature of the first sliding sleeve 25. The depth is not less than 1 / 3 of the sleeve diameter. It is used to support the first sliding sleeve 25 and achieve axial positioning to prevent the sleeve from rotating and shifting.

[0047] A support plate 22 is welded to one side of the second fixing plate 14 to support the side outer window frame 5. The inner wall of the support plate 22 is provided with a positioning circular groove 15, the bottom inner wall is provided with a positioning rectangular groove 17, and the side wall is provided with a T-shaped groove 21. These grooves are engaged one-to-one with the positioning rod 16, the positioning rectangular plate 18, and the T-shaped block 20 on the limiting block 19 to achieve three-dimensional precise positioning of the side outer window frame. The installation accuracy can reach ±1mm. The limiting block 19 is fixed to the support plate 22 by M8 fastening screws to prevent the side outer window frame 5 from shifting under the action of horizontal force.

[0048] Example 2

[0049] Based on the external window structure in Embodiment 1, this embodiment provides an installation method for the structure, the specific steps of which are as follows:

[0050] Step S1: Mark the installation edge line and elevation control line of the side frame 7 at the external window opening of the building wall; place the two side frames 7 vertically on both sides of the opening, fix them with temporary wooden supports, adjust the verticality and horizontality with a 2m straightedge, and fix them to the wall with M10 expansion bolts after confirming that they are correct; place the bottom frame horizontally between the two side frames, adjust the horizontality of the bottom frame, and ensure that the slope of the drainage slope 12 meets the requirement of 3%-5%; place the top frame 4 on top of the side frames and adjust the elevation to the design position; fix the splice of the bottom frame, top frame and side frame with aluminum alloy angle brackets and self-tapping screws, seal all splice gaps with neutral silicone sealant, and control the sealant gap width to 8-10mm to prevent rainwater leakage, and complete the installation of the internal main frame;

[0051] Step S2: According to the marked lines, mark the expansion bolt hole positions of the first fixing plate 13 and the second fixing plate 14 on the outer side of the wall, corresponding to the installation positions of the middle outer window frame 6 and the side outer window frame 5. Drill holes with an electric drill, with a diameter of 12mm and a depth of 110mm. Clean the dust in the holes with a blower and then drive in M10 expansion bolts. Fit the first fixing plate 13 and the second fixing plate 14 into the expansion bolts respectively. Adjust the verticality and horizontality of the fixing plates to ensure that the positions of the arc groove 27 and the support plate 22 are consistent with the design. Tighten the expansion bolt nuts to complete the fixing of the wall fixing plates.

[0052] Step S3: Place the upper and lower ends of the two side window frames 5 inside the support plates 22 corresponding to the second fixing plate 14, and adjust the verticality and spacing of the side window frames to align them with the side frames 7 of the internal main frame; push the limiting block 19 horizontally into the support plate 22 from the side, and sequentially make the positioning rod 16 fully engage with the positioning round groove 15, the T-shaped block 20 slide into the bottom of the T-shaped groove 21, and the positioning rectangular plate 18 embed into the positioning rectangular groove 17, confirming that each positioning structure is engaged without gaps; use M8 fastening screws to fix the limiting block 19 to the support plate 22, and control the tightening torque at 15-20 N·m to complete the rigid fixation of the side window frames;

[0053] Step S4: Insert the sliding rods 24 of the two central outer window frames 6 into the corresponding first sliding sleeves 25, and adjust the extension length of the sliding rods so that the total width of the two central outer window frames is equal to the distance between the two side outer window frames; place the first sliding sleeves 25 stably in the placement arc groove 27 of the first fixing plate 13, ensuring that the outer wall of the sleeve is completely in contact with the inner wall of the arc groove; push the two central outer window frames 6 to both sides simultaneously so that the insertion rods 23 are fully inserted into the slots 34 of the side outer window frames 5, with the insertion depth of the insertion rods not less than 40mm, check the sealing fit between the insertion rod and the slot; slide the second sliding sleeve 31 to drive the strip plate 32 into the strip groove 33 of the first sliding sleeve 25 until the strip plate is fully inserted and located between the two sliding rods 24, preventing the sliding rods from retracting; use M8 connecting screws to pass through the threaded hole 29 of the first sliding sleeve 25, the threaded groove 30 of the strip plate 32 and the bottom inner wall of the arc groove 27 in sequence, tighten the screws, and complete the overall rigid connection between the middle outer window frame and the side outer window frame and the wall fixing plate;

[0054] Step S5: Tilt and lift the window body 3 so that the top is fully inserted into the internal groove of the top frame 4. Then slowly lower the window body so that the bottom sliding groove 8 is precisely aligned with the support rail 11 at the top of the drainage slope 12. Gently press down on the window body 3 to ensure that the sliding groove 8 and the support rail 11 are fully engaged. Push and pull the window body back and forth 3-5 times to check the sliding flexibility. The sliding resistance should be uniform, without any jamming or abnormal noise. Apply neutral silicone weather-resistant sealant to the joints between the window body and the internal main frame, and to the joints between the exterior window and the wall. The sealant should be continuous and full, without bubbles, breaks, or missed spots. Use a utility knife to clean up any excess sealant and construction debris on site to complete the overall installation of the prefabricated wind-resistant, earthquake-resistant, and energy-saving exterior window structure.
