Description

Technical Field

[0001] This utility model belongs to the field of anti-cracking structure technology, and more specifically, it relates to an anti-cracking structure for mid-span of a large-span beam. Background Technology

[0002] Long-span beams play an important role in building engineering. They are mainly divided into two types: structural units in long-span bridges and long-span beam-slab structures. As an important component of modern building engineering, long-span beams not only represent a structural form that spans a large space, but also reflect the continuous innovation and development of building engineering technology.

[0003] Based on the above, the inventors have discovered the following problem: Currently, large-span beams are constructed using anti-cracking mechanisms to prevent crossbeam cracking, and tensioned beam structures are one such example. However, tensioned beam structures require multiple support columns to be installed at the bottom of the crossbeam during installation, but existing tensioned beam structures cannot pre-fix these support columns during installation, resulting in low installation efficiency.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a mid-span anti-cracking structure for large-span beams, in order to achieve a more practical value. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a mid-span anti-cracking structure for large-span beams, thereby solving the problem of low installation efficiency of support columns on current large-span beams.

[0006] The purpose and effect of this utility model's mid-span crack prevention structure for large-span beams are achieved through the following specific technical means:

[0007] A mid-span crack prevention structure for long-span beams includes a pair of columns, a crossbeam mounted on the top of each column, and multiple support columns. A pair of mounting blocks are mounted on the bottom of each crossbeam. The surface of each mounting block has a groove, and the support column is located within the groove. Slider blocks are mounted on both sides of one end of each support column, and the sliders match the groove. A mechanism for facilitating the installation of the support column is mounted on the surface of one of the mounting blocks.

[0008] Furthermore, the mechanism for facilitating the installation of the support column includes a slot formed on the surface of the mounting block, in which an installation component is installed. Placement steps are provided on both sides of the slot, and connecting plates are installed on both sides of the installation component. The connecting plates are in contact with the placement steps. A first threaded hole is formed on the surface of the placement steps, and a first bolt is also included. The first bolt passes through the connecting plate and rotates into the first threaded hole.

[0009] Furthermore, the support column is connected to the crossbeam via a fixing mechanism.

[0010] Furthermore, the fixing mechanism includes a plurality of second threaded holes opened at the bottom of the crossbeam, and also includes a second bolt, which passes through the slider and rotates into the second threaded hole.

[0011] Furthermore, both ends of the mounting block are fixedly connected to the column.

[0012] Furthermore, the mounting block is made of alloy steel.

[0013] Furthermore, one side of the mounting block is connected to one side of the reinforcing plate, and the other side of the reinforcing plate is connected to the surface of the crossbeam.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model utilizes a combination of an installation block, a sliding groove, a slider, and a mechanism for facilitating the installation of support columns. In use, the first bolt can be unscrewed, allowing the installation component to be removed. The support column is then inserted into the sliding groove through a slot. It's important to note that the width of the support column is less than the width of the slot. When all support columns are positioned within the sliding groove, the connecting plate on the installation component can be aligned with the steps. The first bolt is then installed and tightened. At this point, the support column is suspended in the sliding groove on the installation block and can move within the groove. Therefore, simply move the support column to the appropriate position, fix it, and connect it with a steel cable. This design eliminates the need for support columns during installation, improving installation efficiency. Attached Figure Description

[0027] Example:

[0028] As attached Figure 1 To be continued Figure 3 As shown:

[0029] This utility model provides a mid-span anti-cracking structure for large-span beams, including a pair of columns 1, a crossbeam 2 installed on the top of the columns 1, and multiple support columns 3. A pair of mounting blocks 4 are installed on the bottom of the crossbeam 2. The surface of the mounting blocks 4 is provided with a sliding groove 5. The support columns 3 are located in the sliding groove 5. Slider blocks 6 are installed on both sides of one end of the support columns 3. The sliders 6 match the sliding groove 5. A mechanism 7 for facilitating the installation of the support columns is installed on the surface of one of the mounting blocks 4.

[0030] The mechanism 7 for facilitating the installation of the support column includes a slot 701 formed on the surface of the mounting block 4, in which an installation component 702 is installed. Placement steps 703 are provided on both sides of the slot 701. Connecting plates 704 are installed on both sides of the installation component 702. The connecting plates 704 are in contact with the placement steps 703. A first threaded hole 705 is formed on the surface of the placement steps 703. The mechanism also includes a first bolt 706, which passes through the connecting plate 704 and rotates into the first threaded hole 705.

[0031] By using the mounting block 4, the sliding groove 5, the slider 6, and the mechanism 7 for convenient installation of the support column, the first bolt 706 can be unscrewed first, and then the mounting part 702 can be removed. Then, the support column 3 can be inserted into the sliding groove 5 through the slot 701. It should be noted that the width of the support column 3 is smaller than the slot 701. When all the support columns 3 to be installed are located in the sliding groove 5, the connecting plate 704 on the mounting part 702 can be aligned with the step 703, and then the first bolt 706 can be installed and tightened. At this time, the support column 3 is suspended in the sliding groove 5 on the mounting block 4 and can move within the sliding groove 5. Therefore, it is only necessary to move the support column 3 to a suitable position, fix it, and then connect it with a steel cable. Through the above design, the support column 3 can be installed without supporting it, which improves the efficiency of the installation work.

[0032] The support column 3 is connected to the crossbeam 2 through the fixing mechanism 8.

[0033] The fixing mechanism 8 includes a plurality of second threaded holes 801 opened at the bottom of the crossbeam 2, and also includes a second bolt 802, which passes through the slider 6 and rotates into the second threaded hole 801.

[0034] By using the second threaded hole 801 and the second bolt 802, when in use, simply move the support column 3 to the position of the second threaded hole 801, and then pass the second bolt 802 through the through hole on the slider 6 and turn it into the second threaded hole 801 to complete the fixation of the support column 3.

[0035] The two ends of the mounting block 4 are fixedly connected to the column 1.

[0036] Through the above design, the mounting block 4 can also provide some support for the crossbeam 2.

[0037] The mounting block 4 is made of alloy steel.

[0038] One side of the mounting block 4 is connected to one side of the reinforcing plate 9, and the other side of the reinforcing plate 9 is connected to the surface of the crossbeam 2.

[0039] The support capacity of mounting block 4 can be improved by using reinforcing plate 9.

[0040] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
