A cross-layer climbing frame based on a complex large cantilever staggered structure and its construction method

Abstract

The present invention discloses a cross-layer climbing frame based on a complex large-cantilever staggered-level structure and a construction method thereof. The invention aims to solve the problem that during the construction of high-rise buildings with complex large-cantilever staggered-level structures, the large spacing between adjacent cantilevered staggered levels on the building facade cannot directly form a stable connection with the attached cross-layer climbing frame, which easily leads to insufficient overall stability. The cross-layer climbing frame based on the complex large-cantilever staggered-level structure includes a building wall, cantilevered floor panels integrally formed on the outer wall of the building wall and distributed at large spacings, and attached cross-layer climbing frames distributed along the outer side of the building wall and installed in a vertical stack. Staggered spaces are formed between adjacent cantilevered floor panels, and a vertical frame support mechanism is installed on the main beam of the cantilevered floor panels; a horizontal bracing support mechanism is provided below the upper cantilevered floor panels. The present invention is particularly suitable for the safe construction of buildings with large cantilevered staggered-level structures and has high social use value and application prospects.

Description

Technical Field

[0001] The present invention relates to the field of building technology, and in particular to a cross-layer climbing frame based on a complex large cantilever staggered structure and a construction method thereof. Background Art

[0002] As real estate customers have higher and higher expectations for residential lighting, large-spacing balconies that improve indoor lighting have appeared in the design of high-rise residential buildings, especially duplex villas. That is, balconies are only set up on a certain building floor of the same household. In this way, on the one hand, the distance between the balconies on the upper and lower floors of the residence is expanded, thereby expanding the angle of light entering the residence and making the residence brighter. On the other hand, according to the regulatory documents promulgated by the State Economic Commission in 1982, the large-spacing balconies do not include the area of ​​platforms without permanent roofs or beam grids between two natural layers, which increases the free space for real estate customers and is more popular with real estate customers.

[0003] During the construction of high-rise buildings with complex, large-cantilever, split-level structures, the large spacing between adjacent cantilevered, split-level structures on the building facade prevents a direct, stable connection between attached, cross-level climbing frames. When the climbing frames' connecting trusses are connected as a whole, the uneven support forces at each support point can easily lead to overall instability. To address this issue, we propose a cross-level climbing frame and its construction method for complex, large-cantilever, split-level structures. Summary of the Invention

[0011] Optionally, the free end of the horizontal steel structure beam is connected to the lower end of the vertical rigid tie rod to cooperate with the second wall-attached steel plate and the inner oblique rigid tie rod to position the horizontal steel structure beam at three points and maintain horizontality.

[0012] Optionally, the vertical frame and the diagonal support rods are both I-beam profiles.

[0014] The present invention also provides a construction method for a cross-layer climbing frame based on a complex large cantilever staggered structure, comprising the following steps:

[0015] S1. When the attached cross-layer climbing frame climbs above the lower edge of the corresponding staggered space, several wall-mounted supports are fixed to the main beam of the building's cantilevered floor through pre-buried bolt holes and connected to the attached cross-layer climbing frame to form the lower edge support of the staggered space.

[0020] Among them, the attached cross-layer climbing frame continues to climb as the building construction progresses and remains higher than the corresponding natural building layer for protection.

[0021] The present invention mainly has the following beneficial effects:

[0022] 1.

[0034] The following is combined with Figure 1-4 The present invention is further described with examples:

[0035] Example 1

[0036] A cross-layer climbing frame based on a complex large cantilever staggered structure, refer to the attached Figure 1, comprising a building wall 10, building cantilevered floor panels 101 integrally formed on the outer wall of the building wall 10 and distributed at large intervals, and attached cross-layer climbing frames 80 distributed along the outer side of the building wall 10 and installed in a vertical stack, with staggered spaces formed between adjacent cantilevered floor panels 101. A vertical frame support mechanism for fixing the attached cross-layer climbing frames 80 in the lower section of the staggered space is installed on the main beam of the cantilevered floor panel 10;

[0037] A horizontal bracing support mechanism is provided below the cantilevered floor plate 10 of the upper building for fixing the attached cross-layer climbing frame 80 in the upper position of the staggered space, and the horizontal bracing support mechanism is fixed to the free end of the cantilevered floor plate 10 of the upper building through a number of vertical rigid tie rods 70.

[0038] In this embodiment, Figure 1-2 As shown, the frame support mechanism includes a plurality of vertically arranged vertical frames 20 mounted on the main beam at the free end of the cantilevered floor plate 101 of the building, and a first wall-attached steel plate 201 is fixed to the side wall of the bottom end of the vertical frame 20, and the lower end of the first wall-attached steel plate 201 is attached to and fixed to the outer wall of the free end of the cantilevered floor plate 101 of the building through anchor bolts, and an oblique support rod 40 is obliquely mounted on the upper end of the vertical frame 20 close to the building wall 10, and a horizontal steel plate 401 is fixed to the other end of the oblique support rod 40, and the horizontal steel plate 401 It is fixed to the upper end of the cantilevered floor 101 of the building by anchor bolts; the first wall-attached steel plate 201 and the horizontal steel plate 401 both serve to increase and reinforce the bearing surface, ensuring the stable bolting effect of the anchor bolts; the upper end of the vertical frame 20 away from the building wall 10 is symmetrically and obliquely installed with two external oblique hard tie rods 50, and the other end of the external oblique hard tie rod 50 is fixed to the side wall of the free end of the cantilevered floor 101 of the building by anchor bolts. In this embodiment, the vertical frame 20 and the diagonal support rod 40 are both I-beam profiles.

[0039] In this embodiment, Figure 3-4As shown, the cross bracing support mechanism includes a number of horizontal steel structure beams 60 arranged at the same height in the upper section of the staggered space. In this embodiment, the horizontal steel structure beam 60 is an I-beam profile. A second wall-attached steel plate 601 is fixed to one end of the horizontal steel structure beam 60 close to the building wall 10, and the second wall-attached steel plate 601 is fixed to the outer wall of the building wall 10 by anchor bolts. The second wall-attached steel plate 601 increases and reinforces the bearing surface to ensure the stable bolting effect of the anchor bolts. The upper side of the free end of the horizontal steel structure beam 60 is obliquely connected to an inner oblique rigid tie rod 602, and the inner oblique rigid tie rod 602 is fixed to the outer wall of the building wall 10. The other end is fixed to the lower section of the bent steel plate 603, and the upper end of the bent steel plate 603 is fixed to the vertical section of the building cantilevered layer 101 close to the building wall 10 by anchor bolts. It can be understood that the bent part of the bent steel plate 603 is close to the bottom end of the building cantilevered layer 101 to ensure that the bent steel plate 603 will not be deformed after installation and extend the diagonal length; the free end of the horizontal steel structure beam 60 is connected to the lower end of the vertical pull hard rod 70 to cooperate with the second wall-attached steel plate 601 and the inner diagonal pull hard rod 602 to enable the horizontal steel structure beam 60 to be positioned at three points to maintain horizontality.

[0040] In this embodiment, Figure 1 、 3 As shown in FIG. 4 , the upper end of the vertical frame 20 facing away from the building wall 10 , the free end of the building cantilevered floor plate 101 , and the free end of the horizontal steel structure beam 60 are all equipped with wall-attached supports 30 for supporting and fixing the attached cross-layer climbing frame 80 .

[0041] In this embodiment, Figure 1-3 As shown, the outer oblique rigid tie rod 50, the inner oblique rigid tie rod 602 and the vertical rigid tie rod 70 have the same structure, and all include an internally threaded steel pipe, two adjusting screws respectively screwed on the head and tail ends of the internally threaded steel pipe, and a connecting end rotatably mounted on the free end of the adjusting screw; in this embodiment, the middle portion of the internally threaded steel pipe can be flat or provided with a flat handle to facilitate telescopic adjustment. It can be understood that rotating the internally threaded steel pipe can achieve synchronous extension or contraction of the two adjusting screws;

[0042] In this embodiment, in the vertical frame support mechanism, the vertical frame 20 is erected and fixed on the main beam of the cantilevered floor plate 101 of the building, and cooperates with the diagonal bracing rod 40 and the two external diagonal rigid tie rods 50 to form a four-directional reinforcement of the vertical position of the vertical frame 20 to avoid the displacement of the position of the vertical frame 20. The wall-attached support 30 is added to the upper part of the vertical frame 20, which effectively increases the support of the corresponding attached cross-layer climbing frame 80 in the lower part of the staggered space, and the external diagonal rigid tie rod 50 can freely adjust the telescopic length. During the construction process, the telescopic length of the external diagonal rigid tie rod 50 can be adjusted according to the vertical displacement of the vertical frame 20 to achieve the effect of telescopic support and diagonal pulling;

[0043] In the horizontal bracing support mechanism, the horizontal steel structure beam 60 is fixed on the building wall 10 at the upper section of the staggered space, and cooperates with the inner oblique rigid tie rod 602 and the vertical rigid tie rod 70 to maintain the horizontal steel structure beam 60 at three points and avoid the displacement of the horizontal steel structure beam 60. The wall-attached support 30 is added to the free end of the horizontal steel structure beam 60, which effectively increases the support of the corresponding attached cross-layer climbing frame 80 at the upper section of the staggered space. The inner oblique rigid tie rod 602 and the vertical rigid tie rod 70 can both be freely adjusted in telescopic length. During the construction process, the telescopic length of the inner oblique rigid tie rod 602 and the vertical rigid tie rod 70 can be adjusted according to the horizontal displacement combination of the horizontal steel structure beam 60 to achieve the effects of telescopic support and oblique and vertical pulling.

[0044] By installing vertical support mechanisms and horizontal support mechanisms in the same staggered-level space, the connection stiffness and bearing capacity of the climbing frames between complex large cantilevered staggered levels of buildings (residential buildings) can be greatly improved, and the height space between the large cantilevered staggered levels of the building can be effectively structurally anchored. At the same time, the upper, middle and lower three-section support and fixing effect of the attached cross-level climbing frame 80 can be achieved, ensuring stable support for the attached cross-level climbing frame 80 in large-spacing staggered spaces, and also improving the overall stability of the installation of the attached cross-level climbing frame 80.

[0045] In this embodiment, the anchor bolts are all M30 through-bolts, which effectively transfer the bearing capacity of the attached cross-layer climbing frame 80 to the building wall 10 and the main beam, so that the strength meets the design requirements.

[0046] Example 2

[0047] An embodiment of the present invention further provides a construction method for a cross-layer climbing frame based on a complex large cantilever staggered structure, comprising the following steps:

[0048] S1. When the attached cross-layer climbing frame 80 climbs above the lower edge of the corresponding staggered space, several wall-mounted supports 30 are fixed to the main beam of the cantilevered floor plate 101 through pre-buried bolt holes and connected to the attached cross-layer climbing frame 80 to form the lower edge support of the staggered space. At this time, the first natural building layer in the staggered space is constructed;

[0049] S2. When the building construction progresses to the second natural building layer in the staggered space, several vertical support mechanisms are fixed vertically along the outer edge of the building cantilevered layer 101 through pre-buried bolt holes on the main beam of the building cantilevered layer 101. Then, the vertical support mechanisms are connected to the attached cross-layer climbing frame 80 to form the support of the attached cross-layer climbing frame 80 for the second natural building layer in the staggered space;

[0050] Specifically, the vertical frame 20 and the diagonal brace 40 are first assembled on the main beam of the building cantilevered floor 101, and the first wall-attached steel plate 201 at the lower end of the vertical frame 20 is fixed along the outer edge of the building cantilevered floor 101 through the pre-buried bolt holes and anchor bolts so that the vertical frame 20 is fixed vertically. The upper end of the vertical frame 20 on the side away from the building wall 10 is connected to the attached cross-layer climbing frame 80 through the wall-attached support 30;

[0051] S3. When the building construction progresses to the third natural building layer in the staggered space, several cross-bracing support mechanisms are horizontally fixed on the building wall 10 through pre-buried bolt holes. The cross-bracing support mechanisms are then connected to the attached cross-layer climbing frame 80, forming a support for the attached cross-layer climbing frame 80 by the third natural building layer in the staggered space.

[0052] Specifically, the second wall-attached steel plate 601 of the horizontal steel structure beam 60 is fixed to the building wall 10 of the third natural building layer in the staggered space through pre-buried bolt holes and anchor bolts. Subsequently, an inner diagonal rigid tie rod 602 is installed on the upper side of the free end of the horizontal steel structure beam 60, and a bent steel plate 603 is installed on the other end of the inner diagonal rigid tie rod 602. The upper end of the bent steel plate 603 is fixed to the vertical section of the cantilevered floor plate 101 close to the building wall 10 through anchor bolts. The free end of the horizontal steel structure beam 60 is connected to the attached cross-layer climbing frame 80 through the wall-attached support 30.

[0053] S4. When the building construction progresses to the cantilevered deck 101 of the upper floor, a vertical rigid tie rod 70 is fixed to the free end of the horizontal support mechanism, and the other end of the vertical rigid tie rod 70 is fixed to the main beam of the cantilevered deck 10 of the upper floor by anchor bolts;

[0054] S5. As the building construction progresses, repeat steps S1-S4 to complete the support and climbing of the attached cross-layer climbing frame 80 on the complex large cantilevered staggered structure building;

[0055] Among them, the attached cross-layer climbing frame 80 continues to climb as the construction progresses and maintains a height higher than the corresponding natural building layer for protection, generally at least half a natural building layer higher. It can be understood that the climbing drive mechanism of the attached cross-layer climbing frame 80 is an electric hoist. This technology is existing technology and will not be repeated here.

[0056] For other structures not described, refer to Example 1.

[0057] According to the cross-layer climbing frame and its construction method based on the complex large cantilever staggered structure in the above-mentioned embodiment of the present invention, the vertical frame support mechanism and the cross-bracing support mechanism are installed in each staggered space, which can greatly improve the climbing frame connection stiffness and bearing capacity between the complex large cantilever staggered floors of the building (residence), effectively structurally anchor the height space between the large cantilever staggered floors of the building, and at the same time achieve the upper, middle and lower three-section support and fixing effect of the attached cross-layer climbing frame 80, ensure the stable support of the attached cross-layer climbing frame 80 in the large-spacing staggered space, and also improve the overall stability of the installation of the attached cross-layer climbing frame 80.
