Description

Technical Field

[0001] The utility model relates to the field of climbing frame attachment supports, in particular to a temporary steel structure system of climbing frame attachment supports used for staggered balconies. Background Art

[0002] As the requirements for residential quality become higher and higher, a type of two-story residential unit with staggered balconies has emerged. The balcony is usually set on the lower floor, and the balcony on the upper floor is eliminated, leaving only the inner beams of the balcony, so as to ensure that the lower balcony has better lighting and vision.

[0003] However, traditional methods of attaching climbing frames during construction often rely on the building's external structure. By installing the frame's attachment brackets at fixed locations on each floor, the frame is temporarily fixed and easily raised or lowered. This requires the building's external structure to be standard on each floor. Buildings with staggered balconies cannot meet these requirements and cannot be properly used with climbing frames.

[0004] In response to the above problems, the patent with publication number CN217759950U discloses a solution, which is to use different attachment supports at single and double-layer positions, use extended attachment supports at floors without balconies, and install the attachment supports inside the upper inner beams of the balcony (such as the attachment of the patent). Figure 1 This solution places the attachment support in a cantilevered state, which changes the structural stress and makes the single-layer and double-layer structures subject to different stresses. During the ascent of the climbing frame, the structural stress changes continuously, which is not conducive to safety control. In addition, the extended cantilever section of the attachment support also needs to be installed with an extended pull rod to prevent the cantilever end of the attachment support from sinking. The extended attachment support and pull rod are large in size, and there is no foothold on the floor without a balcony, which makes it inconvenient to install.

[0005] Therefore, it is necessary to design a solution that is suitable for split-level balconies, safe, reliable and easy to install. Utility Model Content

[0006] The utility model aims to provide a temporary steel structure system for a climbing frame attachment support at a staggered balcony, which is suitable for staggered balconies and is safe, reliable and easy to install.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a temporary steel structure system for climbing frame attachment supports at staggered balconies, including steel columns, which are supported on the lower balcony. A connecting arm is horizontally provided at the upper end of the steel column, and the connecting arm is used to connect with the attachment support. A balancing arm is horizontally provided between one end of the connecting arm away from the attachment support and the upper inner beam, and the balancing arm is used to balance the bending moment generated by the tension of the attachment support on the steel column.

[0008] The beneficial effects of this program are:

[0009] 1. Set up columns on the lower balcony so that the upper end of the steel column is at a height similar to the inner beam of the upper balcony. Set a connecting arm at the upper end of the steel column to facilitate the connection between the attachment support and the connecting arm. Since the attachment support is directly installed on the connecting arm, it does not need to be lengthened or a pull rod is required. It is suitable for staggered balconies, safe, reliable and easy to install.

[0010] 2. The height of the climbing frame usually covers more than four floors. The attached support at the top of the climbing frame mainly functions to prevent overturning and mainly balance the horizontal tension. Therefore, in this solution, the connecting arm and the balancing arm are both set horizontally to balance the horizontal tension brought by the attached support at the top of the climbing frame. At the same time, the balancing arm is connected to the upper inner beam to prevent the steel column from overturning.

[0011] 3. The lower balcony itself is also a cantilever structure. Therefore, the closer the steel column is to the inner beam of the balcony, the smaller the bending moment it generates on the lower balcony. However, in order to install the upper-level attachment support, the longer the length of the connecting arm is, the greater the bending moment generated by the connecting arm on the steel column. Therefore, a balancing arm is required to balance the bending moment generated on the steel column, prevent deformation of the steel column, and ensure construction safety.

[0012] Furthermore, the steel column, connecting arm and balancing arm are all lattice structures, and a diagonal brace is provided on both sides of the steel column, and the lower end of the diagonal brace is connected to the lower balcony.

[0013] Furthermore, a rubber shock-absorbing support is provided at the bottom of the steel column.

[0014] Furthermore, the connecting arm is a truss structure formed by connecting several rectangular tubes. A pair of clamps are provided at one end of the connecting arm close to the attachment support. The two clamps are connected by bolts and clamp the rectangular tube at the end of the connecting arm. The two clamps are provided with through holes at corresponding positions, and the through holes are used for the screw rod of the attachment support to pass through.

[0015] Furthermore, the height of the connecting arm is greater than the height of the balancing arm, and the upper surface of the connecting arm is flush with the upper surface of the balancing arm.

[0016] Furthermore, the top of the steel column and the lower surface of one end of the connecting arm are detachably connected, and the end of the balancing arm and the side surface of the same end of the connecting arm are detachably connected.

[0017] Furthermore, a set of climbing frames is equipped with one more connecting arms and balancing arms than steel columns.

[0018] This solution also has the following effects:

[0019] 1. The height of the climbing frame usually covers more than four floors, and the top floor is usually a newly poured floor. If there is no balcony on the top floor, and the strength of the newly poured concrete structure is insufficient, the balancing arm and the balcony inner beam cannot be directly connected; in this method, the steel column and the connecting arm can be erected first, and the balancing arm is not installed for the time being. A diagonal brace is installed on both sides of the steel column to prevent the steel column from overturning. The lower ends of the balcony and the diagonal brace are connected to the balcony on the lower floor. Compared with the top floor, the concrete of the next floor has a longer solidification time and higher concrete strength, which can provide effective support for the steel column, thereby balancing the tension of the corresponding attachment support of the top floor of the climbing frame.

[0020] 2. Rubber shock-absorbing supports are installed at the bottom of the steel columns to reduce the shaking of the overall structure when the climbing frame is faced with external forces such as wind loads.

[0021] 3. In the prior art, a screw is usually used to pass through the attachment support and the beam of the main structure at the same time, so that the attachment support is installed on the beam of the main structure. In this solution, a connecting arm is used instead of the beam as the installation point of the attachment support, and a screw is used to pass through the attachment support and the through-hole at the same time, and the attachment support can be installed by tightening it with a nut.

[0022] 4. The connecting arm not only needs to bear the tension of the attached support, but also needs to transfer the shear force to the steel column; while the connecting arm only needs to bear the tension of the attached support, so the cross-sectional area (height) of the connecting arm needs to be larger than the cross-sectional area (height) of the balancing arm; since the connecting arm and the balancing arm are mainly subjected to tension on the upper side, and the lower side is mainly subjected to compression under the support of the steel column, in order to better transfer the tension, the upper surface of the connecting arm is flush with the upper surface of the balancing arm.

[0023] 5. In the existing technology, usually no attachment support is set at the bottom of the climbing frame. However, in order to prevent the bottom of the climbing frame from tilting inward, an attachment support is sometimes set at the bottom. However, the attachment support here mainly bears pressure and almost does not need to bear vertical loads. Therefore, in this solution, after the climbing frame is climbed, the steel column at the bottom of the climbing frame can be removed in advance, leaving only the balancing arm and the connecting arm as horizontal support, and the steel column is moved to the top floor to build a new temporary steel structure system, thereby maximizing the material turnover rate.

[0024] Before the climbing frame is lifted again, disconnect the balancing arm and the connecting arm to completely dismantle the temporary steel structure system of that layer. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example

[0031] The temporary steel structure system for the climbing frame attachment support at the staggered balcony is suitable for the staggered balcony. The staggered balcony includes a lower balcony 10 and an upper inner beam 9. The upper inner beam 9 is retracted inward relative to the lower balcony 10. In this embodiment, the connection method between the steel structure and the concrete structures such as the lower balcony 10 and the upper inner beam 9 is: pre-embedded steel plates in the concrete, and then the steel structure and the steel plates are bolted together.

[0032] The embodiment is basically as follows Figure 1 As shown: A temporary steel structure system for a climbing frame 8 attached to a support 7 for a staggered balcony includes a steel column 1. The lower end of the steel column 1 is connected to and supported by a lower balcony 10. A connecting arm 2 and a balancing arm 3 are horizontally provided at the upper end of the steel column 1. The steel column 1, the connecting arm 2, and the balancing arm 3 are all truss structures formed by welding a plurality of rectangular tubes, which is also a lattice steel structure.

[0033] The upper end of the steel column 1 and the lower surface of the left end of the connecting arm 2 are bolted together. A pair of clamps 4 are provided at the right end of the connecting arm 2. The two clamps 4 are connected by bolts and clamp the rectangular tube at the right end of the connecting arm 2. The two clamps 4 are provided with through holes at corresponding positions. The through holes are used for the screw rod 6 of the attachment support 7 to pass through, so as to facilitate the installation of the attachment support 7.

[0034] The left end of the connecting arm 2 is bolted to the right end of the balancing arm 3, and the left end of the balancing arm 3 is connected to the upper inner beam 9. The balancing arm 3 is used to balance the bending moment generated by the tension of the attached support 7 on the steel column 1. The height of the connecting arm 2 is greater than the height of the balancing arm 3, and the upper surface of the connecting arm 2 is flush with the upper surface of the balancing arm 3.

[0035] The method of using the temporary steel structure system of the climbing frame 8 and the attachment support 7 for the staggered balcony is as follows:

[0036] 1. Use one set of this embodiment for every two floors (including the lower balcony 10 and the upper inner beam 9), such as Figure 2 As shown, when the top floor is a floor without a balcony, the steel column 1 and the connecting arm 2 are first erected, and the balancing arm 3 is not installed yet. A diagonal brace 5 is bolted to the front and back sides of the steel column 1 to prevent the steel column 1 from overturning. The diagonal brace 5 is a steel pipe, and the lower end of the diagonal brace 5 is connected to the lower balcony 10.

[0037] 2. After climbing, if Figure 3 As shown, when the lowest floor is a floor without a balcony, the steel column 1 at the corresponding position at the bottom of the climbing frame 8 is removed, leaving only the balancing arm 3 and the connecting arm 2 as horizontal supports, and the steel column 1 is moved to the top floor to set up a new temporary steel structure system, thereby maximizing the material turnover rate. Therefore, a set of climbing frames 8 is equipped with one more connecting arm 2 and balancing arm 3 than steel column 1.
