Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a through-beam bolt sleeve tool. Background Technology

[0002] During the construction of main structures such as equipment rooms and pump rooms in industrial plants, monorail suspension beams are installed to meet the needs of subsequent equipment installation and daily maintenance. Monorail suspension beams are generally suspended from the bottom of the concrete main beam by bolts that pass through it. In order to meet this installation requirement of monorail suspension beams, through bolt sleeves need to be pre-embedded in the monorail suspension beams.

[0003] The common practice for through-beam bolt sleeves is as follows: Positioning reinforcing bars are welded to the outer wall of the bolt sleeve. These positioning reinforcing bars extend in the same direction as the main reinforcing bars or stirrups of the monorail beam and are welded together. (See attached diagram.) Figure 1 In the above process, the welded connection area between the positioning reinforcement and the outer wall of the bolt sleeve (circular) is small, making it prone to weld breakage during concrete pouring and vibration. This can lead to displacement of the bolt sleeve, making it impossible to guarantee the high installation accuracy requirements of the bolt sleeve. In severe cases, it can affect the subsequent installation and use of the monorail beam. In addition, the positioning reinforcement extends and is welded to the main reinforcement or stirrups of the monorail beam in the same direction. To ensure the stability of the connection, a relatively long weld is generally used. Therefore, the heat generated by welding is relatively large, which can cause heat loss in the main reinforcement or stirrups of the monorail beam, thereby reducing its structural strength.

In the description of this utility model, it should be noted that unless otherwise expressly specified and limited, the terms "set" and "connected" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two elements. Those skilled in the art can understand the specific meaning of the above terms in this utility model through specific circumstances.

[0032] Reference Appendix Figure 1-4 This utility model provides a through-beam bolt sleeve tooling, which includes: bolt sleeve 1, positioning component 2 and end sealing component 3. The positioning component 2 is located on the outside of the bolt sleeve 1 and is used to suspend the bolt sleeve 1. The suspension method replaces the traditional "welding of positioning steel bars to the main reinforcement or stirrups 5 of the monorail beam", which can avoid heat loss of the main reinforcement or stirrups 5 of the monorail beam and ensure its structural strength. The end sealing component 3 is located at the axial end of the bolt sleeve 1 and is used to seal the port of the bolt sleeve 1 to prevent the concrete slurry of the monorail beam from entering the bolt sleeve 1 and blocking it, so as to avoid affecting the later use of the bolt sleeve 1.

[0033] To improve the connection stability between the positioning component 2 and the bolt sleeve 1, and the positioning accuracy of the bolt sleeve 1, this embodiment configures the positioning component 2 as including: a suspension belt 21 and a suspension rib 22. The bottom end of the suspension belt 21 is positioned at the axial end of the bolt sleeve 1, and the top end is bent to form a connecting bolt 23. The suspension belt 21 is made of steel, such as a steel strip, and its top end is bent to rest on the top surface of the monorail beam template 6. The connecting bolt 23 vertically penetrates the suspension belt 21 and connects to the monorail beam template 6 to ensure the positional stability of the suspension belt 21. The bottom end of the suspension rib 22 is sleeved on the bolt sleeve 1. The side wall has a top bend to form a hook 24. The suspension bar 22 is made of steel, and its bottom end forms a semi-enclosed connection with the bolt sleeve 1. Welding is then used to ensure the connection stability between the two. Compared with the traditional positioning bar connection method, the connection area between the suspension bar 22 and the bolt sleeve 1 in this technical solution is larger and the connection stability is higher. The hook 24 formed after the top of the suspension bar 22 is bent can be hung on the stirrup 5 at the top of the monorail beam. The middle part of the suspension bar 22 is vertical and tied to other stirrups 5 in the monorail beam to improve the positional stability of the suspension bar 22 and the bolt sleeve 1.

[0034] By adopting the above technical solution, not only is the connection stability between the suspension rib 22 and the bolt sleeve 1 improved, but also the bolt sleeve 1 is connected and positioned in multiple directions by the suspension belt 21 and the suspension rib 22, which can ensure the accuracy of its position, elevation and other parameters.

[0035] Reference Appendix Figure 3 The end-sealing assembly 3 includes a positioning tube 31, an end-sealing plate 32, and a sealing gasket 33. The end-sealing plate 32 is positioned at the axial end of the positioning tube 31, and the two are coaxially placed inside the bolt sleeve 1. The main function of the positioning tube 31 is to fix the end-sealing plate 32 to the end of the bolt sleeve 1. The sealing gasket 33 is positioned on the side of the end-sealing plate 32 away from the positioning tube 31, and its outer periphery abuts against the inner wall of the bolt sleeve 1. In practice, to facilitate the installation of the positioning tube 31 and the end-sealing plate 32, the inner diameter of the bolt sleeve 1 is greater than the diameter of the end-sealing plate 32 and greater than or equal to the outer diameter of the positioning tube 31. That is, the radial dimensions of the positioning plate and the end-sealing plate 32 are both smaller than the inner diameter of the bolt sleeve 1. This will result in a gap between the outer periphery of the end-sealing plate 32 and the inner wall of the bolt sleeve 1. In this case, a larger sealing gasket 33 is selected and placed on the outside of the end-sealing plate 32 (i.e., the side away from the positioning tube 31) to block the gap and prevent concrete slurry from seeping into the bolt sleeve. Generally, the diameter of the sealing gasket 33 can be slightly larger than the inner diameter of the bolt sleeve 1. Since the sealing gasket 33 is generally flexible, it can be smoothly filled into the bolt sleeve 1 and provide a good sealing effect for the gap.

[0036] The sealing gasket 33 can be either annular or circular. When an annular gasket is used, the bottom end of the suspension belt 21 can be welded to the end plate 32 or bolted to it. When a circular gasket is used, the bottom end of the suspension belt 21 can be bolted to the sealing gasket 33 and the end plate 32.

[0037] To facilitate installation and removal, two sets of positioning tubes 31 are arranged opposite each other. The opposite ends of the two sets of positioning tubes 31 are respectively fixedly connected to end-sealing plates 32, and the following conditions apply: the length of the two sets of positioning tubes 31 + the thickness of the two sets of end-sealing plates 32 < the length of the bolt sleeve 1 ≤ the length of the two sets of positioning tubes 31 + the thickness of the two sets of end-sealing plates 32 + the thickness of the two sets of sealing gaskets 33. In this way, the positioning tubes 31 can be installed and removed from both axial ends of the bolt sleeve 1, improving efficiency.

[0038] In addition, a flange ring plate 4 is fitted on the axial end of the through-beam bolt sleeve 1. The outer diameter of the flange ring plate 4 is greater than the outer diameter of the through-beam bolt sleeve 1. The flange ring plate 4 can increase the contact area with the concrete and improve the connection stability between the through-beam sleeve and the concrete.

[0039] Grouting holes 41 and overflow holes 42 can also be constructed on the flange ring plate 4. When the through-beam bolt sleeve 1 is in the installed state, the overflow hole 42 is higher than the overflow hole 42. After removing part of the cast formwork 6, grout can be injected from the grouting hole 41. When the grout overflows from the overflow hole 42, it means that the gap between the through-beam sleeve and the monorail beam concrete has been filled with grout. After the grout has solidified, the formwork can be completely removed.

[0040] When using the above-mentioned through-beam bolt sleeve tooling for construction, the following steps are included:

[0041] (1) The casting form 6 for the monorail lifting beam is set up, and the main reinforcement and stirrups 5 of the monorail lifting beam are arranged in it;

[0042] (2) Determine the size of the bolt sleeve 1 to be processed according to the screw specifications and the size of the monorail lifting beam; determine the size of the positioning tube 31 according to the size of the bolt sleeve 1, the thickness of the sealing plate, the thickness of the sealing gasket 33, etc., and process the positioning tube 31 into two sections to facilitate the removal of the positioning tube 31 after construction is completed; the diameter of the sealing plate is slightly smaller than the inner diameter of the bolt sleeve 1 to facilitate its installation into the bolt sleeve 1.

[0043] (3) Weld the positioning tube 31 and the sealing plate into two groups, and insert the positioning tube 31 of the two groups into the bolt sleeve 1 so that the ends of the two groups of positioning tube 31 abut against each other, and connect the sealing plate to the opposite ends of the two groups to prevent the sealing plate from shifting; weld the flange ring plate 4 to the axial end of the bolt sleeve 1.

[0044] (4) Install the sealing gasket 33 to the outside of the sealing plate, connect the suspension belt 21 to the sealing gasket 33 and the sealing plate; and put the suspension rib 22 on the outside of the bolt sleeve 1 and weld it.

[0045] (5) Lower the bolt sleeve 1 into the casting template 6 of the monorail beam so that the axial end face of the bolt sleeve 1 abuts against the inner wall of the casting template 6; after determining the position and elevation of the bolt sleeve 1, use the connecting bolt 23 to fix the suspension belt 21 to the top surface of the template 6, and suspend and tie the suspension bar 22 to the stirrup 5 of the monorail beam.

[0046] (6) Cast the monorail lifting beam, and remove the formwork after solidification. After removing the formwork, fill the grout through the grouting hole 41 on the flange ring plate 4. After the grouting solidifies, remove all the formwork.

[0047] Flange ring plate 4 and suspension rib 22 remain in the monorail lifting beam along with bolt sleeve 1; suspension belt 21, sealing gasket 33, sealing plate and positioning tube 31 can be removed from bolt sleeve 1 and reused.

[0048] Compared with the prior art, the beneficial effects of this utility model include at least the following: by replacing the traditional "welding method of positioning steel bars and main bars or stirrups 5 of monorail beam" with a suspension method, heat loss of main bars or stirrups 5 of monorail beam can be avoided, ensuring its structural strength; the end-sealing component 3 prevents concrete slurry of monorail beam from entering the bolt sleeve 1 and blocking it, thus avoiding affecting the later use of bolt sleeve 1; the setting of positioning component 2 in this device not only improves the connection stability between suspension bar 22 and bolt sleeve 1, but also ensures the accuracy of its position, elevation, etc. by forming a multi-directional connection and positioning of bolt sleeve 1 through suspension belt 21 and suspension bar 22.

[0049] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
