Description

Technical Field

[0001] This utility model relates to the field of curtain wall construction technology, specifically to a steel truss structure for installing curtain walls at doorways. Background Technology

[0002] In modern building curtain wall design, to achieve an aesthetically pleasing and transparent facade, the curtain wall needs a reliable supporting structure to withstand its own weight and external loads. However, during construction, traditional supporting structures often face a series of technical challenges when the curtain wall encounters doorways.

[0003] Typically, reinforced concrete structures or steel beams cast in two stages are used as lintels for doorways. However, neither can support the weight of the curtain wall, especially when the doorway is wide and has windows at the top. If the curtain wall is directly supported by the secondary structural beams above the doorway, it is difficult to meet the overall support requirements of the curtain wall, making it difficult to guarantee the stability of the curtain wall and posing a safety hazard.

[0004] To address the issue of insufficient support from secondary structural beams, existing curtain wall construction typically involves adding suspension components to the curtain wall structure above the doorway to provide additional support. However, these suspension components are often located in the space above the window, which can affect the installation of the window above the doorway and easily block natural light, impacting indoor lighting.

[0005] Therefore, it is necessary to study a steel truss structure for installing curtain walls at doorways. Utility Model Content

[0006] Therefore, the purpose of this utility model is to provide a steel truss structure for installing curtain walls in doorways, which can effectively solve the problem that existing doorway lintels cannot support the curtain wall structure and that setting up suspension components will affect window installation and lighting.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A steel truss structure for installing a doorway curtain wall includes a fixing plate, a rib seat, and a truss beam;

[0009] The fixing plate is used to fix the left and right inner walls of the door opening by anchors, and the end face of the fixing plate is vertically installed with rib seats at intervals above and below.

[0010] The truss beams are horizontally distributed between two fixed plates, and the ends of the truss beams are supported in the vertical direction between the vertically spaced rib seats.

[0011] The left and right ends of the truss beam are respectively fixed to the fixed plate, and are simultaneously fixedly connected to the corresponding upper and lower rib plate seats.

[0012] The outer side of the truss beam is provided with an installation structure for installing the curtain wall keel.

[0013] Furthermore, the truss beam includes at least two sets of truss bodies arranged at intervals, and a connecting frame is fixedly connected between the two sets of truss bodies.

[0014] Furthermore, both ends of the truss body are fixed to two sets of fixing plates, and rib plate seats are provided at the upper and lower ends of the two sets of truss bodies respectively.

[0015] Furthermore, the truss body includes an upper chord, a lower chord, and web members. The upper chord and the lower chord are parallel to each other, and multiple web members are connected end to end between the upper chord and the lower chord.

[0016] Furthermore, the rib plate seat is fixedly connected to the fixed plate via the first connector and to the truss beam via the second connector.

[0017] Furthermore, the installation structure includes multiple sets of curtain wall supports vertically fixed to the front end face of the truss beam, with vertical keels fixedly connected between two corresponding sets of curtain wall supports, and horizontal keels fixedly connected to the outer end faces of the curtain wall supports and the vertical keels on the same plane. The horizontal keels are located in front of the door opening and extend to the left and right.

[0018] Furthermore, the transverse keel includes an upper frame and a lower frame arranged at intervals, both of which are L-shaped and arranged facing each other.

[0019] The beneficial effects of the above technical solution are:

[0020] This invention utilizes truss beams instead of secondary structural beams such as reinforced concrete, resulting in better load-bearing capacity, making it particularly suitable for situations with large doorway spans. The two ends of the truss beams are fixedly connected to a fixing plate and reinforced with rib seats, improving the strength of the connection node and ensuring reliable connection. The fixing plate is secured to the left and right inner walls of the doorway using anchors, forming a reliable fixed foundation. In practical engineering applications, this provides a stable supporting foundation for the curtain wall, eliminating the need for a suspension structure to provide additional support at the doorway. This avoids the suspension structure occupying the construction space above the windows, thus preventing obstruction of window construction and lighting effects.

[0021] In summary, this utility model effectively solves the problem that existing doorway lintels cannot support the curtain wall structure, and that setting up suspension components would affect window installation and lighting. It ensures the purpose of the curtain wall suspension on the building facade while achieving the aesthetic effect and quality of the facade. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0028] This embodiment aims to provide a steel truss structure for a doorway 5 without a suspended structure. It is mainly used in curtain wall construction when the doorway 5 has a large span and has doors and windows. It addresses the problem that the existing lintels of the doorway 5 cannot support the curtain wall structure, and that setting up a suspended component would affect the installation of windows and lighting.

[0029] A steel truss structure for a doorway without a suspended structure, such as Figure 1 It includes a fixing plate 1, a rib seat 2, and a truss beam 3. The fixing plate 1 is a 12mm thick hot-dip galvanized steel plate with 8 through holes of 20mm in diameter. The fixing plate 1 is fixed to the left and right inner walls of the door opening 5 by anchors 4, specifically to the frame columns on both sides of the upper part of the door opening 5. The anchors 4 are M18*220mm chemical anchors.

[0030] Rib seat 2 is vertically welded at intervals on the end face of the fixing plate 1. The rib seat 2 is a 150*60 steel rib cut from a steel plate.

[0031] The truss beam 3 includes at least two sets of truss bodies 301 arranged at intervals from front to back, with the front-to-back direction being... Figure 1 In the front-to-back direction, a connecting frame 302 is welded between the two sets of truss bodies 301; the truss body 301 includes an upper chord 303, a lower chord 304, and web members 305. The upper chord 303 and the lower chord 304 are parallel to each other. Multiple web members 305 connected end to end are welded between the upper chord 303 and the lower chord 304. Multiple vertical web members 305 are also welded between the upper chord 303 and the lower chord 304. The upper chord 303 and the lower chord 304 are both 160*80*5 Q235B galvanized square tubes, and the web members 305 are 80*60*5 Q235B galvanized square tubes.

[0032] The truss beam 3 is hoisted to a designated elevation above the doorway 5 by a crane, positioning it horizontally between two spaced-apart rib seats 2. There are a total of eight rib seats 2, with four fixed to each fixed plate 1. Both ends of the truss body 301 are fixed to the two sets of fixed plates 1, and the upper and lower ends of the two sets of truss bodies 301 are correspondingly fixed with rib seats 2. Ultimately, the left and right ends of the truss beam 3 are welded to the two fixed plates 1, and simultaneously fixedly connected to the corresponding upper and lower rib seats 2. During welding, the lower rib seats 2 can be fixed first, and the truss beam 3 can be positioned by hoisting. Then, the upper rib seats 2 can be fixed, and finally, the truss beam 3 can be welded and fixedly connected to the fixed plates 1. This allows the truss beam 3 to be pre-positioned by the rib seats 2, ensuring that the truss beam 3 is in a stable state when welding to the fixed plates 1, reducing hoisting and positioning work, and improving the accuracy and quality of welding.

[0033] In this embodiment, the rib seat 2 is L-shaped and is fixedly connected to the fixing plate 1 via the first connector 6 and to the truss beam 3 via the second connector 7. Both the first connector 6 and the second connector 7 are high-strength bolt sets. The first connector 6 and the second connector 7 allow the rib seat 2 to be pre-positioned before being fully welded and fixed to the truss beam 3, making the subsequent welding process more stable, reliable, and convenient. In other embodiments, welding can also be used to fix the rib seat 2 to the fixing plate 1 and to the truss beam 3.

[0034] The outer side of the truss beam 3 is provided with an installation structure for installing the curtain wall keel. Specifically, multiple sets of curtain wall supports 8 are vertically welded to the front end face of the truss beam 3. Each set of curtain wall supports 8 includes two sets of hot-dip galvanized square steel pipes arranged at intervals on the left and right. Vertical keels 9 are fixedly connected between the two sets of curtain wall supports 8, which are also hot-dip galvanized square steel pipes. They are welded between the two sets of hot-dip galvanized square steel pipes arranged at intervals on the left and right in the curtain wall supports 8, so that the outer end faces of the curtain wall supports 8 and the vertical keels 9 are on the same plane. Horizontal keels 10 are welded and fixedly connected to the outer end faces of the curtain wall supports 8 and the vertical keels 9. The horizontal keels 10 are located in front of the doorway 5 and extend to the left and right. The horizontal keels 10 are used to install the curtain wall, so that there is a gap between the curtain wall and the front end face of the doorway 5, which has a good visual effect and construction space.

[0035] The horizontal keel 10 includes an upper frame 1001 and a lower frame 1002 arranged at intervals. Both the upper frame 1001 and the lower frame 1002 are L-shaped and arranged facing each other to facilitate the installation of curtain wall panels.
