Description

Technical Field

[0001] This utility model relates to a lattice column positioning guide frame, belonging to the field of building construction technology. Background Technology

[0002] In deep foundation pit support engineering, lattice columns, as crucial supporting structural components, directly impact the stability and safety of the entire foundation pit support system through their installation accuracy. Traditional lattice column installation methods lack effective guiding devices when inserting the columns into their predetermined underground positions. They rely primarily on rough manual positioning and the assistance of large machinery, making it difficult to ensure the precise vertical and horizontal positioning of the lattice columns. This can easily lead to problems such as column tilting and displacement, resulting in difficulties in subsequent construction and even affecting the overall performance of the foundation pit support structure, increasing project risks and costs. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, this utility model provides a lattice column positioning guide frame, which can accurately guide the lattice column during installation and improve the installation accuracy of the lattice column.

[0004] This utility model is achieved through the following technical solution: a lattice column positioning guide frame, characterized in that: it includes an upper frame, a lower frame, and four columns. Both the upper and lower frames include two parallel first crossbeams and two parallel second crossbeams arranged between the two first crossbeams. The first and second crossbeams are both double-channel steel. The ends of the two second crossbeams are respectively connected to the two first crossbeams by bolts. A U-shaped space is formed between the first and second crossbeams. The four columns are respectively connected to the four corners of the upper and lower frames, and the upper and lower ends of the columns are respectively welded to the corresponding first crossbeams. The first and second crossbeams of the upper frame and the first and second crossbeams of the lower frame are each threaded with two horizontally arranged adjusting screws perpendicular to the crossbeams, corresponding to the U-shaped space.

[0005] When using this utility model for construction, the guide frame is fitted onto the outside of the lattice column and placed at the opening below the lattice column. The position of the lattice column can be adjusted by the adjusting screws set on the upper and lower frames, which can accurately position the lattice column and provide precise guidance during the installation process, thereby improving the installation accuracy of the lattice column.

[0006] Furthermore, to accommodate lattice columns of different specifications, multiple threaded holes that mate with adjusting screws are provided on the first and second crossbeams of the upper frame and the first and second crossbeams of the lower frame. Depending on the specifications of the lattice column, the threaded holes at the appropriate positions can be matched with the adjusting screws to adjust the lattice column.

[0007] Furthermore, to facilitate the connection between the first and second crossbeams, end plates with bolt holes are fixedly installed at both ends of the second crossbeam, and connecting plates with bolt holes are fixedly installed at the connection between the side of the first crossbeam and the second crossbeam.

[0008] Furthermore, to facilitate the extension of the crossbeam, an end plate with bolt holes is fixed to the end of the first crossbeam and / or a connecting plate with bolt holes is fixed to the outer sides of both ends of the first crossbeam. Through the bolt holes provided on the end plate and connecting plate, the extension piece can be quickly connected to the end or side of the first crossbeam.

[0009] Furthermore, horizontal supports are connected to both ends of the first crossbeam of the lower frame and / or to the outer surfaces of both ends of the first crossbeam. These horizontal supports are made of double-channel steel, and each end of the horizontal support is fixed with an end plate having bolt holes. The horizontal supports are bolted together with the end plates of the first crossbeam of the lower frame or the connecting plates on the outer surfaces of both ends of the first crossbeam. By providing horizontal supports, the size of the lower frame can be increased, facilitating the placement of the guide frame.

[0010] Furthermore, the column is a single channel steel.

[0011] The beneficial effects of this utility model are as follows: The adjusting screws on the guide frame provide precise guidance for the lattice column from all directions, effectively preventing tilting and offset during installation, greatly improving the installation accuracy of the lattice column, and ensuring the stability and reliability of the foundation pit support structure. This utility model simplifies construction, streamlines the installation process of the lattice column, reduces the time spent on repeated adjustments due to installation errors, and enables the lattice column to be installed quickly and accurately, improving the overall construction efficiency of the foundation pit support project. Using this utility model, while improving the installation accuracy of the lattice column, it reduces rework and repair work caused by improper installation, reduces waste of construction materials and labor costs, and significantly lowers construction costs. Furthermore, the guide frame of this utility model is reusable, further saving construction costs. This utility model adopts a detachable modular structure, which can easily adapt to the installation requirements of lattice columns of different specifications, has strong adaptability, improves the versatility and utilization rate of the equipment, and is suitable for the construction requirements of various foundation pit support projects.

[0030] The present invention will be further described below through non-limiting embodiments and in conjunction with the accompanying drawings:

[0031] As shown in the attached diagram, a lattice column positioning guide frame includes an upper frame, a lower frame, columns 5, and adjusting screws 3. The upper and lower frames have identical structures and dimensions. Both the upper and lower frames include two parallel first crossbeams 1 and two parallel second crossbeams 2 arranged between the two first crossbeams. Both the first and second crossbeams 1 and 2 are double-channel steel sections, arranged back-to-back with a gap between them for the adjusting screws 3 to pass through. The two crossbeams are connected as one unit by multiple welded plates on both sides. The ends of the two second crossbeams 2 are connected to the sides of the two first crossbeams 1 by connecting bolts 4, forming a U-shaped space in the middle after the two first crossbeams 1 and two second crossbeams 2 are connected. The upper and lower frames are arranged vertically and vertically. There are four columns 5, which are respectively connected to the four corners of the upper and lower frames. The upper and lower ends of the columns 5 are welded to the corresponding first crossbeams of the upper and lower frames, respectively. The columns 5 are preferably made of single channel steel with the back of the channel steel facing outward. On the first and second crossbeams 1 and 2 of the upper frame and the first and second crossbeams 1 and 2 of the lower frame, there are two horizontally arranged adjusting screws 3 corresponding to the U-shaped spatial threaded connection. The connecting plate 1.3 of the first crossbeam is provided with threaded holes 1.4 that cooperate with the adjusting screws 3, and the connecting plate 2.1 of the second crossbeam is also provided with threaded holes 2.2 that cooperate with the adjusting screws 3.

[0032] To facilitate the connection between the second crossbeam 2 and the first crossbeam 1, it is preferable that end plates 2.3 with bolt holes are fixedly installed at both ends of the second crossbeam 2, and the end plates 2.3 are welded to the ends of the second crossbeam 2; a connecting plate 1.5 with bolt holes is fixedly installed at the connection between the side of the first crossbeam 1 and the second crossbeam 2, and the connecting plate 1.5 is welded to the side of the first crossbeam 1, with the bolt holes on the side of the first crossbeam 1 corresponding to the through holes on the connecting plate 1.5.

[0033] During lattice column installation, the guide frame is fitted onto the outside of the lattice column. The guide frame can be placed on the protective casing, and the top surface of the protective casing needs to be adjusted to be level. The position of the lattice column can be precisely positioned by adjusting the position of the lattice column using the adjusting screws 3. When adjusting the position of the lattice column, the end of the adjusting screw 3 rests on the angle steel of the lattice column. During the lowering of the lattice column, it can be guided by the adjusting screws 3, which can avoid tilting and offset problems during the installation process and greatly improve the installation accuracy of the lattice column. When the guide frame cannot be fitted from above the lattice column, three sides of the guide frame can be installed first, and after fitting the uninstalled side into the lattice column, the remaining side of the crossbeam can be installed.

[0034] To accommodate lattice columns of different specifications, it is preferable that multiple threaded holes for cooperating with adjusting screws 3 are provided on the first and second crossbeams of the upper frame and the first and second crossbeams of the lower frame. The adjusting screws 3 can be installed in the threaded holes at appropriate locations according to the specifications of the lattice column.

[0035] When installing lattice columns, if the guide frame is not securely placed due to mud at the borehole opening, or if the diameter of the casing is too large to accommodate the guide frame, horizontal support legs 6 can be connected to the crossbeams of the lower frame to increase the size of the lower frame. (See attached...) Figure 11 As shown, a horizontal support leg 6 can be connected to each end of the two first crossbeams 1 of the lower frame; or as shown in the attached diagram. Figure 12 As shown, a horizontal support leg 6 is connected to each end of the two first crossbeams 1 of the lower frame, and to the outer side of each end of the two first crossbeams 1, forming a "well"-shaped structure to increase the size of the lower frame. The horizontal support legs 6 also use double-channel steel, and end plates 6.1 with bolt holes are welded to each end of the horizontal support legs 6. To facilitate quick splicing of the horizontal support legs 6 with the first crossbeams 1 of the lower frame, it is preferable to fix end plates 1.6 with bolt holes to both ends of the first crossbeams 1 of the lower frame, and to fix connecting plates 1.5 with bolt holes to the outer side of both ends of the first crossbeams 1 of the lower frame. To facilitate interchangeability between the upper and lower frames, end plates 1.6 with bolt holes can also be fixed to both ends of the first crossbeams 1 of the upper frame, and connecting plates 1.5 with bolt holes can also be fixed to the outer side of both ends of the first crossbeams 1 of the upper frame.

[0036] In this embodiment, the lengths of the first crossbeam 1 and the column 5 are 1m, and the length of the second crossbeam 2 is 0.56m. All components—the first crossbeam, the second crossbeam, and the column—are made of 22a channel steel. The dimensions of the guide frame and the profiles used can be varied depending on the actual construction conditions.

[0037] Using this invention for lattice column installation allows for precise guidance of the lattice columns from all directions, effectively avoiding problems such as tilting and offset during installation. This greatly improves the installation accuracy of the lattice columns, ensuring the stability and reliability of the foundation pit support structure. At the same time, it can significantly improve construction efficiency and effectively reduce construction costs.

[0038] The other parts in this embodiment are all existing technologies and will not be described in detail here.
