Description

Technical Field

[0001] The present invention relates to the field of construction, and particularly to an exterior wall panel window opening structure and a construction method for an exterior wall panel window opening. Background Art

[0002] In the construction of building facades, vertical plates are used for the installation of exterior wall panels. The wall panels at the window openings are truncated by the openings and usually need to be reinforced. The current practice is as follows: The wall panels at the upper and lower parts of the window opening are installed by horizontally arranging multiple vertical panels. To meet the force requirements of the wall panels at the opening, vertical reinforcement members directly connected to the main structure are provided on both the left and right sides of the window opening, and horizontal reinforcement members are provided on the upper and lower sides of the window opening. The horizontal reinforcement members are welded to the vertical reinforcement members on both sides, so that the horizontal loads received by the opening part are transmitted to the main structure through the horizontal and vertical reinforcement members.

[0003] However, the prior art has the following problems: First, when the width and height of the window opening are large, the construction is cumbersome and the cost is high. The standard width of the exterior wall panel is usually 600 mm. When the width of the opening is large, a large number of panel joints are required for the upper and lower side walls of the opening, and the construction is relatively cumbersome. Especially when the height of the window opening is large, the net height of the upper side wall of the opening is small, resulting in a small length of the upper side exterior wall panel. If vertical plates are still used for installation, the custom-made finished plates need to be frequently cut and a large number of connecting fittings need to be matched, and the cost is relatively high.

[0004] Second, the force transmission of the upper wall panel of the window opening is complex, the construction operability is poor, and the construction difficulty is large. The upper end of the upper wall panel of the opening is connected to the main structure, and the lower end is connected to the horizontal reinforcement member on the upper side of the opening. To enhance the hanging safety of the vertical panels on the upper side of the opening, it is required to add hanger bars in the joints of all vertical panels on the upper side of the opening. The upper end of the hanger bar is connected to the main structure, and the lower end is connected to the horizontal reinforcement member. This method not only has complex force transmission, but also requires the installation of horizontal reinforcement members and hanger bars first during construction, and then vertical panels are inserted into the gap formed by the hanger bars and horizontal reinforcement members, resulting in poor construction operability and large construction difficulty, and it is difficult to be popularized in engineering practice. Summary of the Invention

[0005] In view of the problems that the current structure of the exterior wall panel window opening in construction uses horizontal arrangement of vertical plates, the operations of cutting and splicing plates are time-consuming, and hanger bars need to be added in the plate joints to assist in force transmission, with complex force transmission, large construction difficulty, and being difficult to be popularized and applied, the present invention provides an exterior wall panel window opening structure with clear force bearing and simple force transmission, and convenient and fast construction, as well as a construction method for the window opening structure.

[0006] To solve the above problems, the technical solution adopted by the present invention is an exterior wall panel window opening structure, which includes an upper main structure and a lower main structure. There are several vertical panels between the upper main structure and the lower main structure. A certain distance is spaced between adjacent vertical panels, and they together with the upper main structure and the lower main structure enclose a window opening; vertical reinforcement members are respectively provided on the two vertical sides of the window opening; an upper horizontal panel is provided at the top of the window opening, and both ends of the upper horizontal panel are fixedly connected to the vertical reinforcement members on both sides through supporting members and / or connecting members; a lower horizontal panel is provided at the bottom of the window opening, and both ends of the lower horizontal panel are respectively fixedly connected to the vertical reinforcement members on both sides through connecting members. In this solution, horizontal panels are used instead of vertical panels at the upper and lower parts of the window opening, reducing the number of wall panels and connecting members, eliminating the need to add hanger bars, avoiding cumbersome and repetitive panel splicing operations, simplifying construction, and also reducing the cutting operations of exterior wall panels, saving construction costs; the self-weight of the horizontal panels is borne by the supporting members on the vertical reinforcement members on both sides of the window opening, and the horizontal loads are transmitted through the connecting members at both ends of the upper and lower horizontal panels and the vertical reinforcement members, with clear force and simple force transmission, and the installation and adjustment of the wall panels are convenient.

[0007] As a preferred implementation of an exterior wall panel window opening structure, the upper main structure is a floor slab or a structural beam of a building, and the lower main structure is a floor slab or a structural beam of a building. As a building load-bearing component, the building floor slab or structural beam provides a stable and reliable supporting body for the entire exterior wall panel window opening structure. Using it as the upper and lower main structures eliminates the need for additional design and construction of a complex support system, simplifies the construction process, reduces construction costs, and at the same time enhances the connection stability between the entire opening structure and the building main body.

[0008] As a preferred implementation of an exterior wall panel window opening structure, the vertical reinforcement member is one or more of C-shaped steel, flat pipe, flat steel, and angle steel; the upper end of the vertical reinforcement member is fixedly connected to the upper main structure, and / or the lower end of the vertical reinforcement member is fixedly connected to the lower main structure, and / or the vertical reinforcement member is fixedly connected to the corresponding side of the vertical panel. Materials such as C-shaped steel, flat pipe, flat steel, and angle steel have high strength and stability. As vertical reinforcement members, they significantly enhance the bearing capacity and anti-deformation ability on both sides of the window opening. Their multi-directional connection with the upper and lower main structures and the vertical panels forms a stable force system, effectively dispersing and transmitting the loads borne by the structure, and improving the safety of the entire exterior wall panel window opening structure.

[0009] As a preferred implementation solution of an exterior wall strip window opening structure, the supporting member is an L-shaped plate, including a first vertical plate and a supporting plate. The first vertical plate is fixedly connected to the vertical reinforcement member, and the supporting plate supports below the upper horizontal strip. The L-shaped supporting member is convenient for manufacturing and installation, improves construction efficiency, can effectively bear the self-weight of the upper horizontal strip, transfers the load to the vertical reinforcement member, makes the installation of the upper horizontal strip more stable, and ensures the stability of the structure.

[0010] As a preferred implementation solution of an exterior wall strip window opening structure, the connecting member is L-shaped, including a second vertical plate and a connecting plate. The second vertical plate is fixedly connected to the vertical reinforcement member. A connecting hole is provided on the connecting plate, and an anchor is provided in the connecting hole. The anchor is connected to the upper horizontal strip or the lower horizontal strip where it is located. The L-shaped connecting member and the anchor are used in combination to achieve a reliable connection between the upper and lower horizontal strips and the vertical reinforcement member, and can effectively transfer the horizontal load; at the same time, this connection method is flexible in installation, easy to operate, convenient for adjusting the positions of the upper and lower horizontal strips during construction, improves the construction accuracy and efficiency, and ensures the integrity and stability of the structure.

[0011] As a preferred implementation solution of an exterior wall strip window opening structure, the anchor includes a baffle. One side of the baffle is vertically provided with a bolt. The end of the bolt away from the baffle is processed with a thread and a nut is installed. The bolt passes through the upper horizontal strip or the lower horizontal strip where it is located and the corresponding connecting hole. The anchor adopts a tension structure, enhances the connection strength between the upper and lower horizontal strips and the connecting member, and can achieve a firm connection by tightening the nut, which is convenient for construction operation and ensures the reliability of the structural connection.

[0012] As a preferred implementation solution of an exterior wall strip window opening structure, first sinking grooves for accommodating the supporting plate are provided at both ends of the bottom surface of the upper horizontal strip. The supporting plate is buried in the first sinking groove, which ensures the flatness of the top surface of the upper exterior wall strip at the window opening and is convenient for plastering and leveling the bottom of the wall panel.

[0013] As a preferred implementation solution of an exterior wall strip window opening structure, second sinking grooves for accommodating the connecting plate are provided on the sides of the upper horizontal strip and the lower horizontal strip. The connecting plate is buried in the second sinking groove, which ensures the flatness of the building elevation at the window opening of the upper and lower horizontal strips, is convenient for plastering and leveling the inner side of the wall panel, and makes the building appearance more beautiful.

[0014] On the other hand, the present invention also provides a construction method for an exterior wall strip window opening, including the following steps: S1. Arrange vertical strips between the upper main structure and the lower main structure, and the interval distance between the vertical strips on both sides of the window opening is the width of the opening; S2. Determine the type of vertical reinforcement members according to the opening size and install them on both sides of the window opening; S3. According to the plate width design of the upper horizontal plate of the opening in the layout drawing, fixedly install the supporting member on the vertical reinforcement member; according to the layout drawings of the upper and lower horizontal strips of the window opening, fixedly install the connecting member on the vertical reinforcement member; S4. Hoist the pre-installed upper horizontal strip with anchor bolts to the upper part of the window opening, use the supporting member as a support, and fixedly connect the anchor bolts of the upper horizontal strip with the connecting member at the upper part of the vertical reinforcement member; hoist the pre-installed lower horizontal strip with anchor bolts to the lower part of the window opening, and fixedly connect the anchor bolts of the lower horizontal strip with the connecting member at the lower part of the vertical reinforcement member.

[0015] As an optimized implementation solution of a construction method for window openings of exterior wall strips, in step S2, the upper and lower ends of the vertical reinforcement member are respectively connected to the upper main structure and the lower main structure by means of mechanical anchor bolts or welding with embedded parts in the structure or direct welding; in step S3, the supporting member is welded to the vertical reinforcement member, and the connecting member is welded to the vertical reinforcement member.

[0016] It can be seen from the above technical solutions that the advantages of the present invention are as follows: The horizontal strips are used to replace the vertical strips for the window opening, greatly reducing the number of wall panels and connecting members, avoiding the addition of suspension bars and cumbersome panel splicing operations, reducing the cutting amount of exterior wall strips, and saving construction costs; using the building floor slab or structural beam as the main structure, without the need for an additional complex support system, simplifying the construction process. The installation of each component is convenient. For example, the L-shaped supporting member and the L-shaped connecting member cooperate with the anchor bolts, and the installation is flexible and convenient for adjusting the position of the horizontal strip, improving the construction accuracy and efficiency; the vertical reinforcement member uses high-strength materials such as C-shaped steel and flat tubes, and is connected to the upper and lower main structures and the vertical strips in multiple directions, enhancing the bearing and anti-deformation capabilities on both sides of the window opening, forming a stable force system, dispersing and transmitting the load, and improving the structural safety. The supporting member bears the self-weight of the upper horizontal strip, and the connecting member transmits the horizontal load, with clear force and simple force transmission. The tension structure of the anchor bolts enhances the connection strength between the strip and the connecting member, ensuring reliable structural connection; the first sinking groove on the bottom surface of the upper horizontal strip accommodates the supporting plate, and the second sinking grooves on the sides of the upper and lower horizontal strips accommodate the connecting plates, ensuring the flatness of the top surface of the window opening and the inner side surface of the building exterior wall, facilitating the plastering and leveling of the wall surface, improving the overall aesthetics of the building, and at the same time, the second sinking groove can also protect the connecting member and extend its service life.

[0024] To make the purpose, features, and advantages of the present invention more obvious and understandable, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in this specific embodiment. Obviously, the embodiments described below are only some embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this patent.

[0025] Embodiment 1 As Figure 1 、 2As shown in the figure, an exterior wall panel window opening structure includes an upper main structure 1 and a lower main structure 2. There are several vertical panels 3 between the upper main structure 1 and the lower main structure 2. The adjacent vertical panels 3 are spaced at a certain distance and together with the upper main structure 1 and the lower main structure 2 enclose a window opening. The spacing distance between the vertical panels 3 on both sides of the window opening is the width of the opening. A strengthening structure is arranged in the window opening. Specifically: Vertical strengthening members 4 are respectively arranged on the vertical edges on both sides of the window opening. The vertical strengthening members 4 can be one or more of C-shaped steel, flat tubes, flat steel, angle steel (and other forms that can be conceived by those skilled in the art). The upper end of the vertical strengthening member 4 is fixedly connected to the upper main structure 1, and / or the lower end of the vertical strengthening member 4 is fixedly connected to the lower main structure 2, and / or the vertical strengthening member 4 is fixedly connected to the corresponding side of the vertical panel 3. As a preferred solution, in this embodiment, the upper and lower ends, as well as the side edges of the vertical strengthening member 4 are fixedly connected to ensure the force requirements of the window opening strengthening structure. Before construction, select appropriate materials such as C-shaped steel, flat tubes, flat steel, angle steel as the vertical strengthening members according to the design requirements and carry out processing; during construction, first fix the upper end of the vertical strengthening member to the upper main structure (such as a floor slab or a structural beam) by means of welding, bolt connection, etc., and the lower end is also connected to the lower main structure. If the design requires the vertical strengthening member to be connected to the vertical panel, further use connectors such as self-tapping screws to fix the two together. When the entire structure bears the load, the vertical strengthening member has high strength and stability.

[0026] On the basis of the vertical strengthening members 4 on both sides, an upper horizontal panel 5 is arranged at the top of the window opening. Both ends of the upper horizontal panel 5 are fixedly connected to the vertical strengthening members 4 on both sides through a support member 6 and a connecting member 7: Such as Figure 3 、 4 As shown, the support member 6 is an L-shaped plate, including a first vertical plate 61 and a support plate 62. The first vertical plate 61 is fixedly connected to the vertical strengthening member 4, and the support plate 62 supports below the upper horizontal panel 5. Combining Figure 1 、 Figure 2, at both ends of the bottom surface of the upper horizontal strip plate 5, there are first sinking grooves 10 for accommodating the supporting plate 62. After the upper horizontal strip plate 5 is installed, the supporting plate is buried in the first sinking groove 10, ensuring the flatness of the upper horizontal strip plate 5 on the top surface of the window opening. The supporting member is installed after the vertical reinforcement member is installed: the first vertical plate of the L-shaped supporting member is fixed to the vertical reinforcement member by bolts or welding, etc., to ensure a firm connection. When installing the upper horizontal strip plate, place it on the supporting plate so that the supporting plate supports the self-weight of the upper horizontal strip plate. At this time, the gravity borne by the upper horizontal strip plate is transmitted to the first vertical plate through the supporting plate, and then from the first vertical plate to the vertical reinforcement member, and finally transmitted to the main building structure.

[0027] The connecting member 7 is L-shaped and includes a second vertical plate 71 and a connecting plate 72. The second vertical plate 71 is fixedly connected to the vertical reinforcement member 4. A connecting hole 73 is provided on the connecting plate 72. The connecting hole preferably adopts an oblong hole, and the length of the oblong hole extends horizontally, which can adapt to different installation positions or installation position errors of the anchor fittings on the horizontal strip plate. An anchor fitting 9 is provided in the connecting hole 73. The anchor fitting 9 is connected to the corresponding upper horizontal strip plate 5 or lower horizontal strip plate 8. A second sinking groove 11 for accommodating the connecting plate 72 is provided on the side surface of the upper horizontal strip plate 5. The connecting plate is buried in the second sinking groove 11, ensuring the flatness of the building elevation of the upper horizontal strip plate 5 at the window opening of the exterior wall strip plate. As Figure 5 shown, the anchor fitting 9 includes a baffle 91. One side of the baffle 91 is vertically provided with an anchor rod 92. The end of the anchor rod 92 far from the baffle 91 is processed with threads and is provided with a nut 93 and a gasket 94. The anchor rod 92 passes through the corresponding upper horizontal strip plate 5 or lower horizontal strip plate 8 and the corresponding connecting hole 73. After tightening the nut 93, one of the baffle 91 and the gasket 94 presses against the connecting plate 72, and the other presses against the surface of the lower horizontal strip plate 8. After the installation position of the upper horizontal strip plate or the lower horizontal strip plate is determined, the second vertical plate of the connecting member is fixedly connected to the vertical reinforcement member by welding or bolts. Then, the anchor fitting passes through the connecting hole of the connecting plate and the reserved hole on the corresponding strip plate. After the anchor fitting passes through the strip plate, install a gasket and a nut at the other end and tighten them to make the upper and lower horizontal strip plates fit tightly with the connecting plate, realizing a reliable connection between the upper and lower horizontal strip plates and the vertical reinforcement member. When the structure bears horizontal loads, the horizontal force is transmitted to the anchor fitting through the upper and lower horizontal strip plates, then from the anchor fitting to the connecting plate, and finally transmitted to the vertical reinforcement member through the second vertical plate, thereby effectively transmitting the horizontal load to the main building structure.

[0028] A lower horizontal strip plate 8 is provided at the bottom edge of the window opening. Both ends of the lower horizontal strip plate 8 are fixedly connected to the vertical reinforcement members 4 on both sides through connectors 7. The structure of the connectors 7 here is the same as that of the connectors used for the upper horizontal strip plate 5 mentioned above. A second sinking groove 11 for accommodating the connecting plate 72 of the connector 7 is also provided on the side surface of the lower horizontal strip plate 8. The connecting plate 72 is embedded in the second sinking groove 11, ensuring the flatness of the building elevation of the lower horizontal strip plate 8 at the window opening of the exterior wall strip plate.

[0029] The upper main structure 1 is a floor slab or a structural beam of a building, and the lower main structure 2 is a floor slab or a structural beam of a building. When the upper main structure and the lower main structure are floor slabs or structural beams made of reinforced concrete, embedded parts are pre-buried in the floor slab, and both ends of the vertical reinforcement member are welded to the embedded parts, or mechanical anchor bolts are used for connection; when the structural beams of the upper main structure and the lower main structure are steel beams, the vertical reinforcement member can be directly welded to the structural beam.

[0030] Embodiment 2 Based on the exterior wall strip plate window opening structure provided in Embodiment 1, this embodiment further provides a construction method for an exterior wall strip plate window opening to construct the aforementioned window opening structure.

[0031] The construction method includes the following steps: S1. Determine the type and specification of the vertical reinforcement member according to information such as the window opening size. According to the layout drawing, install the vertical strip plates sequentially from the opening to both sides, and reserve the positions of the opening and the vertical reinforcement member. S2. Fix the vertical reinforcement members on both sides of the opening. The upper and lower ends of the vertical reinforcement members are directly connected to the structural beam or the floor slab by means of mechanical anchor bolts, welding with the embedded parts in the structure, or direct welding, and the sides are connected to the vertical strip plates by self-tapping screws. S3. Install the supporting members. According to the plate width design of the upper horizontal strip plate of the opening in the layout drawing, weld the supporting members to the vertical reinforcement members to support the self-weight of the upper horizontal strip plate of the window. S4. Install the connectors. According to the layout drawing of the horizontal strip plates at the upper and lower parts of the window opening, weld the short sides of the connectors to the vertical reinforcement members, and ensure that the inner anchor bolts of the pre-installed horizontal strip plates are closely adjacent to the long side steel plates of the connectors. S5. Lift the upper horizontal strip plate of the window to the designated position of the opening, use the supporting members welded to the vertical reinforcement members as its support, and sequentially connect the upper horizontal plate of the window to the vertical reinforcement members from bottom to top by using connectors and anchor bolts. S6. Lift the lower horizontal plate of the window to the designated position of the opening, use the floor slab or the structural beam as the support, and sequentially connect the lower horizontal strip plate of the window to the vertical reinforcement members from bottom to top by using connectors and anchor bolts.

[0032] As can be seen from the above embodiments, the beneficial effects of the present invention are as follows: the window opening uses horizontal slats instead of vertically installed plates, reducing the number of wall panels and connectors, avoiding the addition of hanging bars and cumbersome panel splicing operations, reducing the cutting amount of exterior wall slats, and saving construction costs; using the building floor slab or structural beam as the main structure, without the need for an additional complex support system, simplifying the construction process. The installation of each component is convenient. For example, the L-shaped support and the L-shaped connector cooperate with the anchor to install flexibly and facilitate the adjustment of the slat position, improving the construction accuracy and efficiency; the vertical reinforcement members are made of high-strength materials such as C-shaped steel and flat tubes, and are connected to the upper and lower main structures and the vertical slats in multiple directions, enhancing the bearing and anti-deformation capabilities on both sides of the window opening, forming a stable force system, dispersing and transferring loads, improving the structural safety. The support bears the self-weight of the upper horizontal slat, and the connector transfers the horizontal load, with clear force and simple force transmission. The anchor's tension structure enhances the connection strength between the slat and the connector, ensuring reliable structural connection; the first sink on the bottom surface of the upper horizontal slat accommodates the support plate, and the second sink on the side surfaces of the upper and lower horizontal slats accommodates the connecting plate, ensuring the flatness of the top surface of the window opening and the inner facade of the building, improving the overall aesthetics of the building. At the same time, the second sink can also protect the connector and extend its service life.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention will not be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
