Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular, to a backtop support structure for a garage. Background Art

[0002] In construction projects, the construction site at the construction site is getting smaller and smaller. It is often necessary to carry out stacking, driving, and construction on the top slab of the completed underground garage. Since the design load of the construction garage often cannot meet the requirements of the construction load, it is necessary to carry out backtop support for the top slab of the underground garage. The design and implementation of the backtop plan for the underground garage top slab play a crucial role in the safety and stability of the basement. The design of the backtop plan for the underground garage should consider the load conditions of the underground garage to ensure that the system can withstand the forces of the garage itself and external loads. The design of the backtop plan for the underground garage should also ensure the stability during the long-term use of the underground garage, and avoid the deformation or damage of the top slab caused by load changes.

[0003] In the related art, when carrying out backtop support for the garage, the general method is an independent support system, which requires a large amount of manpower and material resources. The independent support system uses independent steel pipes to support the upper top slab and beams. After the concrete compressive strength reaches 100%, the full hall formwork is removed, and the independent support steel pipes are used for backtop support.

[0004] In the above solution, the support steel pipes are used for backtop support. Although the structural form is relatively simple, if the top slab load is too large during the subsequent use of the garage, resulting in vibration or the problem of garage floor settlement, it is very easy to cause the support steel pipes to tilt. The tilted steel pipes not only pose a great threat to the safety of personnel, but also cannot play a good support effect. Therefore, the support structure in the related art has the defect of poor stability. Summary of the Invention

[0029] The following further describes the present application in detail Figure 1-6 in conjunction with the accompanying drawings.

[0030] An embodiment of the present application discloses a support structure for a garage ceiling. Referring to Figure 1 , a support structure for a garage ceiling includes a plurality of strut assemblies 1 and a plurality of connection assemblies 2. The plurality of strut assemblies 1 are evenly distributed at intervals along the garage ceiling area, and adjacent two strut assemblies 1 are connected and fixed by one connection assembly 2, and the connection assembly 2 is located at the top of the strut assembly 1.

[0031] Referring to Figure 1 and Figure 2 , the strut assembly 1 includes a support steel pipe 11, a top adjusting member 12 and a bottom adjusting member 13.

[0032] Referring to Figure 1 , Figure 2 and Figure 3 , the support steel pipe 11 is vertically arranged in the ceiling area in the garage. The top adjusting member 12 includes an orifice plate 121, an adjusting screw 123, an adjusting nut 124, a support plate 125 and a cross beam steel 126. At least two perforations 1211 are formed through the orifice plate 121 in the thickness direction. In this embodiment, three perforations 1211 are formed. Correspondingly, three adjusting screws 123 and three adjusting nuts 124 are also respectively provided. In other embodiments, the adjusting screws 123 and the adjusting nuts 124 can be selected according to the number of openings on the orifice plate 121, and the number thereof is not a limitation to the present application.

[0033] Referring to Figure 2 , Figure 3 and Figure 4, the orifice plate 121 is located at the top of the support steel pipe 11. Three adjusting screws 123 are respectively installed in cooperation with three through holes 1211. One end of the adjusting screw 123 penetrates through the through hole 1211, and the end of the adjusting screw 123 passing through the through hole 1211 extends into the support steel pipe 11. The diameter of the orifice plate 121 is larger than the pipe diameter of the support steel pipe 11. The adjusting nut 124 is threadedly connected to a section of the adjusting screw 123 located on the orifice plate 121, and the outer diameter of the adjusting nut 124 is larger than the aperture of the through hole 1211 on the orifice plate 121. The support plate 125 is welded to the top of the adjusting screw 123.

[0034] Referring to Figure 1 and Figure 2 , the crossbeam steel 126 is horizontally arranged on the support plate 125. The top of the crossbeam abuts against the top of the garage. A concave hole 1261 corresponding to the support plate 125 is opened at the bottom of the crossbeam steel 126, and the support plate 125 is located in the concave hole 1261. By arranging the crossbeam steel 126, the contact area between the support structure and the garage roof can be increased, thereby enhancing the support stability of the support structure. Arranging the concave hole 1261 can improve the stability of the contact between the top of the support steel column and the crossbeam steel 126, and prevent the crossbeam steel 126 from falling off the support plate 125.

[0035] Referring to Figure 1 and Figure 2 , the bottom adjusting member 13 includes a sleeve 131 and a driving part. The sleeve 131 is vertically arranged at the bottom of the support steel pipe 11, and a square base 134 is integrally welded to the bottom of the sleeve 131. A slider 111 is fixedly connected to the side wall of the support steel pipe 11. A chute is axially opened on the inner wall of the sleeve 131, and the bottom of the support steel pipe 11 is slidably connected to the chute of the sleeve 131 through the slider 111.

[0036] Referring to Figure 1 and Figure 2 , the driving part includes a driving ring 132 and an operating ring 133. The driving ring 132 is coaxially rotatably connected to the top of the sleeve 131, and the driving ring 132 is threadedly connected to the bottom of the support steel column. The operating ring 133 is fixedly welded to the side wall of the driving ring 132. When it is necessary to drive the support steel pipe 11 to slide upward through the driving part so as to drive the top of the support steel pipe 11 to abut tightly against the garage roof, an operator can insert a steel pipe into the operating ring 133 and then rotate the steel pipe to drive the driving ring 132 to rotate through the operating ring 133. Since the support steel column slides vertically, when the driving ring 132 rotates, it drives the support steel pipe 11 to slide upward, thereby driving the top of the support steel pipe 11 to abut tightly against the garage roof, and then maintaining a good support effect.

[0037] Referring to Figure 1 and Figure 5The connection assembly 2 includes two inclined fork rods 21, two fixing rings 22 and a locking member 23. The ends of the two inclined fork rods 21 are hinged, and the two fixing rings 22 are respectively hinged to the ends of the two inclined fork rods 21 that are away from each other. The hinge axis between the fixing ring 22 and the ends of the inclined fork rods 21 and the hinge axis between the two inclined fork rods 21 are parallel to each other and are both horizontally arranged. The two fixing rings 22 are respectively sleeved on two adjacent supporting steel pipes 11, and the fixing rings 22 are threadedly connected with a top screw 221 for clamping the fixing rings 22 and the supporting steel pipes 11.

[0038] Reference Figure 5 and Figure 6 The locking member 23 includes a locking screw 231 and two locking nuts 232. A waist-shaped hole 211 is radially penetrated on the bevel fork rod 21. The locking screw 231 is sequentially penetrated through the waist-shaped holes 211 of the two bevel fork rods 21. The two locking nuts 232 are located at both ends of the locking screw 231 and are threadedly connected with the locking screw 231. The locking nuts 232 abut against the bevel fork rods 21. When the angle between the two bevel fork rods 21 needs to be fixed, the locking nuts 232 are rotated so that the locking nuts 232 abut against the bevel fork rods 21, thereby completing the angle fixing of the two bevel fork rods 21.

[0039] The implementation principle of a garage roof support structure in an embodiment of the present application is: when supporting the garage roof, the support steel pipe 11 is vertically abutted against the roof return plate, and then the height of the support plate 125 can be adjusted by rotating the adjusting nut 124, so that the support steel pipe 11 can form an effective support for the garage roof, and placing the crossbeam steel 126 on the support plate 125 can increase the contact area between the support steel pipe 11 and the garage roof.

[0040] Before installing the supporting steel pipe 11, first sleeve the fixing ring 22 on the two adjacent supporting steel pipes 11. The two hingedly arranged inclined fork rods 21 can be suitable for supporting steel pipes 11 with different spacings. When connecting and fixing the two adjacent supporting steel pipes 11 through the connecting assembly 2, first lift the connecting assembly 2 to the top of the supporting steel pipe 11, and then rotate the top screw 221 to fix the fixing ring 22 and the supporting steel pipe 11, and then fix the angle of the two inclined fork rods 21. By rotating the locking nut 232, the locking nut 232 is pressed against the inclined fork rod 21, thereby completing the angle fixation of the two inclined fork rods 21, that is, completing the return support.

[0041] When the garage floor sinks, the supporting steel pipe 11 cannot play a good supporting effect. At this time, the driving part drives the supporting steel pipe 11 to slide upward, thereby driving the top of the supporting steel pipe 11 to press against the garage roof, thereby maintaining a good supporting effect.

[0042] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
