Description

Technical Field

[0001] This invention relates to the field of steel structure construction technology, and specifically to an installation process for the construction of steel structures with large inclination angles. Background Technology

[0002] During on-site construction of steel components, in order to complete the installation of steel components, hoisting structures and temporary connection measures are required to quickly position and fix the steel components. Existing steel component installation generally involves setting up lifting lugs at the top and temporary connection measures such as lugs and clamps at the bottom for the hoisting equipment to connect. For longer steel components, guy ropes are often strung around the perimeter after positioning. When installing steel components at large angles, temporary support measures (such as steel profiles or lattice frames) are usually set up around the structure where the steel components need to be installed, or temporary fixing without guy ropes is used. However, when the required tilt angle of the steel components is large, the number of steel components is large, and the upper installation space is limited, a large number of temporary support structures are required. The installation and dismantling of these support structures are cumbersome, requiring significant manpower and time, resulting in low component installation efficiency and high investment costs for temporary support structures. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is the low installation efficiency and high installation cost of large-angle steel components when hoisting and positioning them in a limited space in the prior art, and thus provides an installation process for the construction of large-angle steel components.

[0051] In this embodiment, as Figures 1-8As shown, the floor connecting points of the building 8 where the steel members 2 need to be connected are all provided with the code plates, and when the steel members 2 are installed, two steel members 2 to be installed can be connected to form a whole steel member 2 which is connected to the first connecting point 801, the middle connecting point 802 and the second connecting point 803 of the building 8. The first connecting point 801, the middle connecting point 802 and the second connecting point 803 are sequentially arranged from the lower layer of the building 8 to the upper layer of the building 8 and are all provided with the code plates. The upper end of the steel member 2 is installed on the second connecting point 803, and the lower end of the steel member 2 is installed on the first connecting point 801. The hoisting method of the lower end of the steel member 2 is the same as the hoisting method of the lower end of the steel member 2 described above, and the hoisting method of the upper end of the steel member 2 is the same as the hoisting method of the upper end of the steel member 2 described above, which will not be described here. Specifically, the third clamping plate 206 located at the connection position of the two steel members 2 is welded to the middle of the steel member 2. After the upper end and the lower end of the steel member 2 are fixed, the bolt is used in cooperation with the third clamping plate 206 to connect and fix the middle of the steel member 2 and the code plate on the middle connecting point 802. In this way, the connection stability between the two steel members 2 connected to form the steel member 2 and the connecting points of the building 8 can be ensured, and the connection strength can be enhanced.

[0052] In the embodiment, the first connecting point 801 is specifically the upper end of the installed steel member 2, the middle connecting point 802 is specifically the corresponding layer plate of the floor above the first connecting point 801, and the second connecting point 803 is specifically the end of the support structure installed on the floor layer plate of the second connecting point 803. In alternative embodiments, the first connecting point, the middle connecting point and the second connecting point can be located on the adjacent lower, middle and upper floor plates of the building, respectively.

In this way, the first clasp and the second clasp 204 can make the lifting connection between the automobile crane 1 and the steel member 2 more convenient, and the second clasp 204 can make the lower end portion slide on the rope more smoothly.

[0056] Specifically, in the S2 step of the embodiment, the end of the first steel wire rope 3 away from the steel member 2 is fixed by a rope clamp 5 to form a knot buckle 401, and a hemp rope 6 is connected on the knot buckle 401. The worker 0 pulls the end of the hemp rope 6 away from the first steel wire rope 3 and connects it to the floor of the first connection point 801.

[0057] In the S3 step of the embodiment, after the steel member 2 is lifted to the position corresponding to the floor of the second connection point 803, the worker 0 pulls the end of the hemp rope 6 on the floor of the first connection point 801 to make the end of the second steel wire rope 4 connected with the hemp rope 6 pulled to the floor of the first connection point 801, then disconnects the connection between the second steel wire rope 4 and the hemp rope 6, and then hangs the knot buckle 401 on the hook head of the electric hoist 7. In this way, the hemp rope 6 can be used for extension before the steel member 2 is lifted, and the first steel wire rope 3 can be pulled to the floor of the first connection point 801 after the steel member 2 is lifted to the corresponding height, so that the length of the first steel wire rope 3 does not need to be adjusted frequently, the time consumed for adjusting the length of the first steel wire rope 3 can be reduced, and the efficiency of hoisting the steel member 2 can be improved.

[0058] In the S4 step of the embodiment, the lower end portion is corrected by the jack and the electric hoist 7 to correspond to the position of the floor of the first connection point 801 to complete the positioning, and then the lower end portion is temporarily connected and fixed with the code plate on the first connection point 801 by using bolts. In this way, the connection accuracy between the lower end portion of the steel member 2 and the installation point can be ensured, so that the installation effect of the steel member 2 can be ensured.

[0059] In the S5 step of the embodiment, the first clamping plate 202 is welded on the side of the upper end opposite to the first lug plate 201, and the second clamping plate 205 is welded on the side of the lower end opposite to the second lug plate 203. After the upper end and the lower end are fixed, the first clamping plate 202 is used to fixedly connect the upper end and the floor of the second connecting point 803, and the second clamping plate 205 is used to fixedly connect the lower end and the floor of the first connecting point 801. In this way, the connection strength between the upper end and the floor of the second connecting point 803 can be further strengthened by the first clamping plate 202, and the connection strength between the lower end and the floor of the first connecting point 801 can be further strengthened by the second clamping plate 205.

After the lower end slides to the designated point and is temporarily fixed, the upper end of the steel member 2 is in place during lifting by the main hook 101, and after the lower end is temporarily fixed, the upper end is fixed at the designated point, and then the lower end is fixed, and then the connection between the main hook 101 and the auxiliary hook 102 of the truck crane 1 and the upper end and the lower end of the steel member 2 is released, that is, the hoisting and installation of the steel member 2 is completed. This installation process is completed by the main devices such as the truck crane 1, the slide cable and the electric hoist 7, without the need to build a support structure in advance, reducing the time investment in the early installation preparation work, effectively improving the hoisting efficiency of the inclined steel member 2, without the need to build a temporary support structure such as a steel member 2 or a lattice cradle, reducing the investment in temporary measures during installation, effectively saving manpower, reducing the time for building and dismantling the support structure, effectively improving the installation efficiency of the large-inclination steel member 2 in the case of limited upper installation space, and reducing the installation cost.
