Specific embodiments

[0049] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present invention belong to the scope protected by the present invention.

[0050] Embodiment 1:

[0051] As Figures 1 - 7 shown, the formwork support system of the high - altitude corridor structure provided in this embodiment includes a profiled steel main beam 4, a profiled steel connecting beam 5, a formwork bottom cushion assembly 6 and a support frame 7, wherein:

[0052] The steel girder main beam 4 extends horizontally, and both ends of the steel girder main beam 4 are respectively connected to the (N - 1)th floors of two buildings. It should be noted that the above-mentioned corridor structure is built between the Nth floors of two buildings, where N is an integer greater than or equal to 3, and the number of the steel girder main beams 4 is several, and several steel girder main beams 4 are arranged side by side longitudinally. The steel girder main beam 4 can be an I-beam. Specifically, the number of the above-mentioned steel girder main beams 4 can be three or four or five or more.

[0053] The steel girder connecting beam 5 extends longitudinally, the steel girder connecting beam 5 is connected to the steel girder main beam 4, and the number of the steel girder connecting beams 5 is several, and several steel girder connecting beams 5 are arranged side by side horizontally. The above-mentioned steel girder connecting beam 5 can also be an I-beam. As can be seen from the above, several steel girder connecting beams 5 are parallel and spaced. Optionally, the spacing between two adjacent steel girder connecting beams 5 is between 0.8 meters and 1 meter. For example, the spacing between two adjacent steel girder connecting beams 5 is 0.8 meters or 1 meter. Optimally, the spacing between two adjacent steel girder connecting beams 5 is 0.9 meters.

[0054] The formwork bottom cushioning assembly 6 is cushioned below the formwork 2 of the corridor structure, and the support frame 7 is erected between the steel girder connecting beam 5 and the formwork bottom cushioning assembly 6, so as to connect the formwork bottom cushioning assembly 6 to the steel girder connecting beam 5 by means of the support frame 7.

[0055] With the above structure, the steel girder main beam 4 and the steel girder connecting beam 5 located on the steel girder main beam 4 are erected on the layer below the corridor structure, so as to form a base. The support frame 7 is erected on the above-mentioned base, and then the formwork bottom cushioning assembly 6 is erected on the support frame 7, and then the formwork 2 of the corridor structure is installed on the formwork bottom cushioning assembly 6, and then the structural beam 1 of the corridor structure is poured by using the above-mentioned formwork. In this way, the entire support system only needs to be built on the lower layer of the corridor structure. Compared with the full hall scaffolding in the prior art, the support system uses less materials, is more convenient to erect and has higher efficiency, and well avoids the overhanging platform between the two buildings from hindering the erection work of the support system. Moreover, since the height of the entire support system is lower than that of the full hall scaffolding, its stability and safety are higher.

[0056] In order to enable the steel girder main beam 4 to provide sufficient supporting force, in this embodiment, when the building is constructed, holes need to be reserved in the wall of the building. Both ends of the steel girder main beam 4 are respectively inserted into the wall reserved holes of the (N - 1)th floors of the two buildings, so that the end of the steel girder main beam 4 is lapped on the floor slab 3 of the (N - 1)th floor of the building, and the depth of the steel girder main beam 4 inserted into the wall reserved hole is at least 1 meter, that is, at least one meter section of one end of the steel girder main beam 4 is lapped on the floor slab 3. In addition, U-shaped bolt retaining rings 12 are installed on the floor slab 3 of the floor, and the end of the above-mentioned steel girder main beam 4 is clamped on the floor slab 3 by means of the U-shaped bolt retaining rings 12.

[0057] Preferably, two diagonal bracing beams 10 are connected to the middle of the profiled steel main beam 4, and the two diagonal bracing beams 10 are respectively connected to two buildings. The diagonal bracing beam 10 is located below the profiled steel main beam 4. In this way, the load-bearing capacity of the profiled steel main beam 4 can be further enhanced. Specifically, one end of the diagonal bracing beam 10 is welded and fixed or fixed by bolts on the middle bottom of the profiled steel main beam 4, and the other end of the diagonal bracing beam 10 is connected to the outer wall of the building or a embedded steel plate 11 embedded in the outer wall.

[0058] An alternative implementation of this embodiment is as follows: The above-mentioned support frame 7 includes vertical steel pipes 71, horizontal steel pipes 72 and longitudinal steel pipes 73. The number of vertical steel pipes 71, horizontal steel pipes 72 and longitudinal steel pipes 73 is several. The several vertical steel pipes 71 are connected to several profiled steel connecting beams 5 through several connecting components 8. The several horizontal steel pipes 72 and several longitudinal steel pipes 73 are arranged vertically and horizontally, and the vertical steel pipes 71, horizontal steel pipes 72 and longitudinal steel pipes 73 are connected by fasteners. The above-mentioned formwork bedding component 6 is installed at the top of several vertical steel pipes 71. In this way, the vertical steel pipes 71 mainly play a load-bearing role, while the horizontal steel pipes 72 and longitudinal steel pipes 73 mainly play a role in enhancing the structural stability of the support frame 7, so as to provide a large enough supporting force for the formwork bedding component 6.

[0059] Of course, the above-mentioned support frame 7 can also be composed of several mechanical jacks and ejector rods. Several of the above-mentioned mechanical jacks are installed on each profiled steel connecting beam 5, and an ejector rod is installed at the top of each mechanical jack. The top of the ejector rod supports the above-mentioned formwork bedding component 6.

[0060] In order to further enhance the structural stability of the support frame 7, in this embodiment, vertical diagonal braces 74 are connected to the horizontal outer facade of the above-mentioned support frame 7 by fasteners, and horizontal diagonal braces (not shown in the figure) are also connected to the top of several profiled steel connecting beams 5. It should be noted that the above-mentioned horizontal diagonal braces and vertical diagonal braces 74 are both "X"-shaped structures formed by the intersection of two steel pipes and locked by fasteners.

[0061] An alternative implementation of this embodiment is as follows: The above-mentioned connecting component 8 includes an upper clamping plate 81, a lower clamping plate 82, a bolt connection pair and a column 84. The above-mentioned profiled steel connecting beam 5 is an I-beam composed of an upper flange, a lower flange and a web. The web is connected between the upper flange and the lower flange, and the lower flange of the profiled steel connecting beam 5 overlaps on the top surface of the profiled steel main beam 4

[0062] One end of the above-mentioned upper clamping plate 81 is integrally formed with a hook portion 811. The upper clamping plate 81 is lapped on the top surface of the upper wing plate, and the hook portion 811 is hooked to one side edge of the upper wing plate. The lower clamping plate 82 is placed below the upper wing plate. The lower clamping plate 82 and the hook portion 811 are respectively located on both sides of the web. The upper clamping plate 81 and the lower clamping plate 82 are connected by the above-mentioned bolt connection pair. When the bolt connection pair is tightened, the upper clamping plate 81 and the lower clamping plate 82 clamp the upper wing plate. The column 84 is integrally formed or fixedly welded on the top surface of the upper clamping plate 81. The column 84 is located directly above the web, and the column 84 is inserted into the lower part of the vertical steel pipe 71, so that the vertical steel pipe 71 is connected to the above-mentioned profiled steel connecting beam 5.

[0063] The above-mentioned connecting component 8 can be stably connected to the profiled steel main beam 4, and when the bolt connection pair is loosened, the position of the connecting component 8 can also be conveniently moved on the profiled steel main beam 4. Specifically, during installation, through measurement, the distance between the central axes of the columns 84 of two adjacent connecting components 8 is 0.8 m - 1 m. For example, the distance between the central axes of the columns 84 of two adjacent connecting components 8 is 0.8 m or 1 m. Optimally, the distance between the central axes of the columns 84 of two adjacent connecting components 8 is 0.9 m.

[0064] Of course, the above-mentioned connecting component 8 can also be a "C"-shaped member that is buckled and covers the upper wing plate, an airbag arranged in the "C"-shaped member, and a column 84 fixedly arranged on the top surface of the "C"-shaped member. After the connecting component 8 is moved in place, the airbag is inflated through the inflation mechanism, so that the airbag expands and presses tightly.

[0065] An alternative implementation manner of this embodiment is as follows: The above-mentioned formwork bedding component 6 includes a steel pipe main beam keel 61 and a square wood secondary beam keel 62. A height-adjustable jack 9 is connected to the top end of the above-mentioned vertical steel pipe 71. The steel pipe main beam keel 61 is connected to the jack 9. The square wood secondary beam keel 62 is lapped on the steel pipe main beam keel 61. The formwork is lapped on the square wood secondary beam keel 62 and fixed by iron nails. It should be noted that both the steel pipe main beam keel 61 and the square wood secondary beam keel 62 are existing technologies during the construction of the high-altitude corridor structure, so no detailed description will be given here.

[0066] Optionally, the above-mentioned jack 9 includes a nut sleeve 91, a screw rod 92, and a support groove 93, wherein:

[0067] The nut sleeve 91 includes a circular tube at the lower part and an inner convex tube at the upper part. The inner wall of the inner convex tube is provided with internal threads. The outer wall of the top end of the vertical steel pipe 71 is provided with a convex ring. The circular tube is rotatably sleeved outside the convex ring. The bottom wall of the inner convex tube is lapped on the top end of the convex ring. The nut sleeve 91 further includes a retaining ring at the bottom end. The retaining ring is sleeved outside the vertical steel pipe 71 and is bolted and fixed to the bottom end of the circular tube. In this way, an annular chamber is formed between the top surface of the circular tube, the retaining ring and the bottom surface of the inner convex tube. The convex ring is placed in the annular chamber, so that the nut sleeve 91 is rotatably installed at the top end of the vertical steel pipe 71. The inner hole of the nut sleeve 91 is coaxial with and communicated with the vertical steel pipe 71. A convex block is further provided on the outer wall of the circular tube to facilitate the construction workers to rotate the circular tube.

[0068] The screw rod 92 is screwed into the internal thread hole of the nut sleeve 91, and the screw rod 92 is inserted into the upper part of the vertical steel pipe 71. The support groove 93 is welded and fixed to the top end of the screw rod 92. The steel pipe of the steel pipe main beam keel 61 is placed in the support groove 93, so as to support the steel pipe main beam keel 61.

[0069] During installation, the construction workers can hold the support groove 93 by hand and then rotate the nut sleeve 91, so as to drive the screw rod 92 to drive the support groove 93 to lift. Of course, when the steel pipe of the steel pipe main beam keel 61 is placed in the support groove 93, the support groove 93 does not need to be held by hand. In this way, it is convenient for the construction workers to adjust the height of the position where the support groove 93 is located according to the situation, so as to make the top support 9 tightly hold the steel pipe main beam keel 61.

[0070] Of course, the nut sleeve 91 can also be made into an internal thread tube with ear plates arranged on the outer wall. The bottom end of the nut sleeve 91 is directly lapped on the top end of the vertical steel pipe 71. In this way, after the steel pipe main beam keel 61 is placed in the support groove 93, the steel pipe main beam keel 61 will limit the support groove 83 and the screw rod 82. In this way, when the nut sleeve 91 is rotated, the screw rod 92 will not rotate. Therefore, when the nut sleeve 91 is rotated, the height of the position where the screw rod 92 is located can also be adjusted, so as to adjust the height of the position where the support groove 93 is located.

[0071] Embodiment 2:

[0072] This embodiment provides a construction method for erecting the formwork support system of the high-altitude corridor structure provided in Embodiment 1 under the corridor structure. This method includes:

[0073] Step 1: Insert both ends of several steel girder main beams 4 into the wall reserved holes on the (N - 1)th floor of two buildings respectively, so that the ends of the steel girder main beams 4 overlap on the floor slab 3 of the (N - 1)th floor of the building, and then fix them with U - bolt snap rings 12. Specifically, when constructing the building, it is necessary to reserve holes in the building walls. Both ends of the steel girder main beams 4 are inserted into the wall reserved holes on the (N - 1)th floor of two buildings respectively, so that the ends of the steel girder main beams 4 overlap on the floor slab 3 of the (N - 1)th floor of the building. Moreover, the depth of the steel girder main beam 4 inserted into the wall reserved hole is at least 1 meter, that is, at least one - meter section of one end of the steel girder main beam 4 overlaps on the floor slab 3. In addition, install U - bolt snap rings 12 on the floor slab 3 of the floor, and the ends of the above - mentioned steel girder main beams 4 are clamped on the floor slab 3 by the U - bolt snap rings 12. After installing the steel girder main beams 4, install two diagonal bracing beams 10 below the steel girder main beams 4. Specifically, one end of the diagonal bracing beam 10 is connected to the bottom surface of the steel girder main beam 4, and the other end of the diagonal bracing beam 10 is connected to the exterior wall of the building or the embedded steel plate 11 preset in the exterior wall. The distance between the connection points between the two diagonal bracing beams 10 and the steel girder main beam 4 is A, the distance between the connection point between the diagonal bracing beam 10 and the steel girder main beam 4 and the corresponding end of the steel girder main beam 4 is B, and the length of the steel girder main beam 4 is L, where B = 2A and B + 2A = L.

[0074] Step 2: Lap several steel beam connectors 5 on several steel girder main beams 4 so that several steel beam connectors 5 are arranged side - by - side on the steel girder main beams 4. Specifically, through measurement, make the distance between adjacent two steel beam connectors 5 be 0.9 meters.

[0075] Step 3: Build a support frame 7 on the steel girder main beam 4. Specifically, first cover the upper splint 81 on the top surface of the upper flange of the steel beam connector 5, so that the hook part 811 of the upper splint 81 hooks on one side edge of the upper flange, then place the lower splint 82 below the upper flange, then install bolt connection pairs between the upper splint 81 and the lower splint 82, and then move the position of the connection assembly 8 so that the upright posts 84 above the upper splint 81 move to the appropriate position (specifically, the distance between the central axes of adjacent two upright posts 84 is 0.9m), and then tighten the bolt connection pairs. After all the connection assemblies 8 are installed in place, then insert several vertical steel pipes 71 into several upright posts 84 in turn, then install transverse steel pipes 72 and longitudinal steel pipes 73 between several vertical steel pipes 71, then install horizontal cross braces on several steel beam connectors 5, and then install several vertical cross braces 74 on the transverse outer facade of the support frame 7. Then install a jack 9 at the top of each vertical steel pipe 71 and rotate the nut sleeve 91 of the jack 9 to adjust the height of the position where the screw rod 92 and the support groove 93 are located, so that the support grooves 93 of all the jacks 9 are close to being flush.

[0076] Step 4: Build the template bottom component 6 on the support frame 7, and then install the template 2 of the corridor structure on the template bottom component 6. Specifically, lap the steel pipe main beam keel 61 on the top support 9, then place the square wood secondary beam keel 62 on the steel pipe main beam keel 61, and then fix the template 2 of the corridor structure on the square wood secondary beam keel 62 with iron nails.

[0077] Through this method, the formwork support system can be erected under the corridor mechanism in a relatively short time, thus saving the construction period, and materials can also be saved, reducing costs.

[0078] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope recorded in the present invention can easily think of changes or substitutions, which should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
