[0002] During the construction of the outer eaves slab in steel structure frame engineering, the profiled steel sheet used as the bottom formwork of the floor slab cannot meet the strength requirements of the large outer eaves. Based on this, the following measures are usually adopted in the existing technology: 1) Add steel beams at the outer eaves end, but this will increase the project cost; 2) Change the profiled steel sheet composite floor slab at the outer eaves end to a cast-in-place floor slab, but this will increase the cost of supporting frame and formwork erection, and the construction period for the installation and dismantling of the frame and formwork will be longer; 3) Weld and install diagonal steel supports on the lower side of the outer eaves section, but this will increase the amount of welding work, increase the project cost, and the installation of diagonal steel supports will occupy construction space and affect the functionality.
[0003] None of the above measures conform to the concept of green environmental protection. Therefore, there is a need to provide a detachable external eaves structure support rod that can solve the above technical problems. Summary of the Invention
[0004] The purpose of this utility model is to provide a detachable outer eaves structure support rod, which can solve the above-mentioned technical problems.
[0005] This utility model is implemented as follows:
[0006] A detachable exterior structure support rod includes an exterior steel beam, a profiled steel sheet installed on top of the exterior steel beam, and a concrete structural slab cast on the profiled steel sheet;
[0007] The detachable eaves structure support rod also includes an adjustable strut, a fixed top rod, and a detachable sleeve rod.

Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0022] Please see the appendix Figure 1 and attached Figure 2 A detachable exterior structure support rod includes an exterior steel beam 1, a profiled steel sheet 2 installed on top of the exterior steel beam 1, and a concrete structural slab 3 cast on the profiled steel sheet 2.
[0023] The exterior steel beam 1, profiled steel sheet 2, and concrete structural slab 3 are conventional components of the exterior structure, and are constructed in accordance with design requirements and conventional processes, which will not be elaborated here.
[0024] Please see the appendix Figure 1 and attached Figure 2 The detachable outer eaves structure support rod also includes an adjustable support rod, a fixed top rod 4, and a detachable sleeve rod 5. The fixed top rod 4 is fixedly installed on the bottom surface of the outer eaves end of the profiled steel plate 2, and the detachable sleeve rod 5 is detachably installed on the lower flange of the outer eaves steel beam 1. The upper end of the adjustable support rod abuts against the fixed top rod 4, and the lower end of the adjustable support rod is rotatably connected to the detachable sleeve rod 5, so that the adjustable support rod is obliquely supported between the outer eaves end of the profiled steel plate 2 and the lower flange of the outer eaves steel beam 1. The fixed top rod 4 and the detachable sleeve rod 5 are arranged parallel to each other along the length direction of the outer eaves steel beam 1, and several adjustable support rods are spaced apart between the fixed top rod 4 and the detachable sleeve rod 5.
[0025] By welding the fixed top rod 4 to the bottom surface of the outer eaves end of the profiled steel sheet 2, it serves as the upper support point for the adjustable strut. Similarly, by attaching the detachable sleeve rod 5 to the lower flange of the outer eaves steel beam 1, it serves as the lower support point for the adjustable strut. This design facilitates construction and prevents slippage. No additional steel beam is needed at the outer eaves end. The detachable sleeve rod 5 and the adjustable strut are detachable, allowing for easy assembly and disassembly, and easy reuse, aligning with green and sustainable development principles. Furthermore, it avoids the need to weld and install diagonal steel supports on the lower side of the outer eaves section. The concrete slab 3 on the profiled steel sheet 2 can be cast-in-place, eliminating the need for support frames and formwork, effectively controlling construction progress and costs.
[0026] Please see the appendix Figure 1 and attached Figure 2 The adjustable support rod includes an upper support rod 6, a lower support rod 7, and an adjusting bolt 8. The upper end of the upper support rod 6 abuts against the fixed top rod 4, and the lower end of the lower support rod 7 is rotatably connected to the detachable sleeve rod 5. The lower part of the upper support rod 6 and the upper part of the lower support rod 7 are adjustablely connected by the adjusting bolt 8.
[0027] Preferably, the upper support rod 6 and the lower support rod 7 can be made of angle steel arranged back to back, and the specifications and length of the angle steel can be selected according to actual needs. The upper support rod 6 and the lower support rod 7 are connected by bolts 8 to form adjustable support rods of different lengths, so as to provide reliable oblique support between the outer end of the profiled steel sheet 2 and the lower flange of the outer steel beam 1.
[0028] Please see the appendix Figure 1 and attached Figure 2 The lower part of the upper support rod 6 and the upper part of the lower support rod 7 are each provided with a number of adjustment holes 9 at intervals. The lower part of the upper support rod 6 and the upper part of the lower support rod 7 are connected in an adjustable manner through the adjustment holes 9 via multiple adjustment bolts 8.
[0029] Preferably, the adjusting bolt 8 can be a high-strength bolt selected according to the support force requirements, used to reliably connect the lower part of the upper support rod 6 and the upper part of the lower support rod 7. The diameter of the adjusting hole 9 is slightly larger than the diameter of the adjusting bolt 8. The number and spacing of the adjusting holes 9 can be adjusted according to the actual adjustment requirements. When the lower part of the upper support rod 6 and the upper part of the lower support rod 7 overlap back to back, their adjusting holes 9 coincide, so that the adjusting bolt 8 can be inserted into the adjusting hole 9, realizing the extension, shortening and disassembly of the adjustable support rod. It can be applied to various models (different heights and widths) of the outer eaves steel beam 1, which is convenient to install and disassemble and has high practicality.
[0030] Preferably, two adjusting bolts 8 can be spaced apart. When working together, the upper and lower support rods form a whole, resulting in good integrity, load-bearing capacity, and high structural strength. During disassembly, only one adjusting bolt 8 needs to be removed, and the other adjusting bolt 8 loosened, to allow relative rotation of the upper support rod 6 and lower support rod 7. This facilitates the installation and removal of the adjustable support rods and makes construction convenient.
[0031] Please see the appendix Figure 1 and attached Figure 2 The upper end of the upper support rod 6 is provided with an end rod 10. The cross-sections of the end rod 10 and the fixed rod 4 are both inverted L-shaped structures. The horizontal section of the fixed rod 4 is fixed to the bottom surface of the profiled steel plate 2. The outer side of the horizontal section and the outer side of the vertical section of the end rod 10 respectively abut against the horizontal section and the vertical section of the fixed rod 4.
[0032] Preferably, both the end support rod 10 and the fixed support rod 4 are made of angle steel. The L-shaped fixed support rod 4 limits the end support rod 10 to prevent slippage, ensuring that the adjustable support rod supports the profiled steel plate 2. The structure is simple, the construction is convenient, and the cost is saved.
[0033] Please see the appendix Figure 1 and attached Figure 2 An upper connecting plate 11 is provided between the inner side of the horizontal section and the inner side of the vertical section of the end rod 10. The upper end of the upper support rod 6 is rotatably connected to the upper connecting plate 11 by an upper rotating bolt 14.
[0034] The upper connecting plate 11 and the upper rotating bolt 14 are used to connect the upper end of the upper support rod 6 and the end rod 10, and can meet the rotation adjustment of the upper support rod 6, thereby realizing the adjustment requirement of the tilt angle of the adjustable support rod to adapt to the length of the outer eaves board. After the adjustment is in place, tighten the upper rotating bolt 14 to ensure the reliability of the connection between the upper support rod 6 and the end rod 10.
[0035] Please see the appendix Figure 1 and attached Figure 2 The detachable sleeve rod 5 has a C-shaped cross-section, and the opening height of the C-shaped structure is slightly greater than the thickness of the lower flange of the outer eave steel beam 1, so that the detachable sleeve rod 5 can be sleeved on the lower flange of the outer eave steel beam 1 through the opening of the C-shaped structure. The fastening bolt 12 is screwed through and screwed onto the lower flange of the detachable sleeve rod 5 and pressed against the bottom surface of the lower flange of the outer eave steel beam 1.
[0036] Preferably, the detachable sleeve rod 5 can be made of C-shaped steel. The specifications of the C-shaped steel can be adjusted according to the thickness of the lower flange of the outer eaves steel beam 1, making it easy to fit onto the lower flange of the outer eaves steel beam 1. The detachable sleeve rod 5 can be set to the same length as the fixed top rod 4, which facilitates the installation of an adjustable support rod between the detachable sleeve rod 5 and the fixed top rod 4.
[0037] The fastening bolt 12 is screwed through the lower flange of the detachable sleeve rod 5 and presses against the lower flange of the outer eaves steel beam 1, ensuring the reliability of the installation of the detachable sleeve rod 5 on the lower flange of the outer eaves steel beam 1, and making disassembly and assembly convenient and quick.
[0038] Please see the appendix Figure 1 and attached Figure 2 An anti-slip pad 16 is provided between the fastening bolt 12 and the lower flange of the outer eaves steel beam 1.
[0039] Preferably, the anti-slip mat 16 can be made of rubber, which has a good anti-slip effect and avoids damage to the surface layer of the lower flange of the outer steel beam 1, thus facilitating the protection of the finished product.
[0040] Please see the appendix Figure 1 and attached Figure 2The detachable sleeve rod 5 has a lower connecting plate 13 on its upper wing plate, and the lower end of the lower support rod 7 is rotatably connected to the lower connecting plate 13 by a lower rotating bolt 15.
[0041] The lower connecting plate 13 and the lower rotating bolt 15 are used to connect the lower end of the detachable sleeve rod 5 and the lower support rod 7, and can meet the rotation adjustment of the lower support rod 7, thereby realizing the adjustment requirement of the tilt angle of the adjustable support rod to adapt to the length of the outer eaves plate (i.e. the length of the profiled steel plate 2 and the concrete structure plate 3 extending out of the outer eaves steel beam 1). After adjustment, tighten the lower rotating bolt 15 to ensure the reliability of the connection between the lower support rod 7 and the detachable sleeve rod 5.
[0042] Please see the appendix Figure 1 and attached Figure 2 The method of use and working principle of this utility model are as follows:
[0043] First, weld the lower connecting plate 13 onto the detachable sleeve rod 5, and then use the lower rotating bolt 15 to connect the lower end of the lower support rod 7 to the lower connecting plate 13.
[0044] The second step is to weld the upper connecting plate 11 onto the end rod 10, and then use the upper rotating bolt 14 to connect the upper end of the upper support rod 6 onto the upper connecting plate 11.
[0045] The third step is to determine the position of the fixing rod 4 based on the length of the outer eaves of the outer eaves panel and the height of the outer eaves steel beam 1, and then weld the fixing rod 4 to the bottom of the profiled steel plate 1.
[0046] The fourth step is to determine the length of the adjustable strut composed of the lower strut 7 and the upper strut 6 based on the distance between the fixed angle steel 10 and the lower flange of the outer eaves steel beam 1, and then determine the position of the adjusting hole 9 for the adjusting bolt 8 to be inserted, and first insert one adjusting bolt 8.
[0047] Fifth step, attach the detachable sleeve rod 5 to the lower flange of the outer eaves steel beam 1, so that the end top rod 10 rests against the inside of the fixed top rod 4, and then insert and install the second adjusting bolt 8.
[0048] Step 6: Place rubber pad 16 between fastening bolt 12 and the lower flange of outer eave steel beam 1, tighten fastening bolt 12, and one adjustable support rod is installed. Install multiple adjustable support rods at intervals between detachable sleeve rod 5 and fixed top rod 4 to complete the installation of detachable outer eave structure support rods.
[0049] Step 7: After the concrete structure slab 3 above the profiled steel plate 2 is poured, loosen the fastening bolts 12 and adjusting bolts 8 to remove the detachable outer eaves structure support rods. The detachable outer eaves structure support rods can be reused.
[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model.
