Description

Technical Field

[0001] This utility model relates to the field of embedded parts technology, and in particular to an adjustable embedded bolt assembly. Background Technology

[0002] In the field of industrial buildings, embedded bolts are required in the foundation or superstructure to fix the superstructure or equipment. Embedded bolts are widely used in industrial buildings and structures.

[0003] Once the pre-embedded bolts are installed after the foundation or upper concrete structure has been poured, they are no longer adjustable, the exposed thread length is fixed, and the material is not replaceable.

[0004] After the pre-embedded components of industrial buildings and structures are poured and installed, the increased load often leads to problems such as foundation settlement, increased load, or inconsistencies between the actual operating conditions and the design. This results in the pre-embedded bolts no longer meeting the operating requirements or becoming damaged, causing numerous issues for the use of the superstructure or equipment. To meet the current operating conditions, the existing structure needs to be reinforced and repaired, which incurs significant costs. Furthermore, in some projects, due to the difficulty of repair, no repair work is carried out, leaving the structure or equipment in a state of extreme use, posing significant safety hazards.

[0005] Therefore, there is an urgent need to develop an adjustable and replaceable pre-embedded bolt that can be adjusted or added or removed from the pre-embedded bolt assembly to meet normal operating conditions when the structure experiences overall or uneven settlement, or to replace the bolt when it is damaged. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide an adjustable pre-embedded bolt assembly, which allows the original bolts to meet normal working conditions by adjusting the bolts or adding or removing pre-embedded bolt assemblies, or to replace the bolts when they are damaged.

[0007] This utility model discloses an adjustable pre-embedded bolt assembly, including a bolt and an adjustment assembly for adjusting the pre-embedded depth of the bolt. The adjustment assembly includes a fixing member for fixing the pre-embedded position of the bolt and an isolation member for separating the pouring of concrete. The fixing member and the isolation member are connected by threads. The bolt passes through the adjustment assembly and is threadedly engaged with the fixing member of the adjustment assembly.

[0008] Furthermore, the adjustment component can adjust the bolt embedment depth by increasing or decreasing the number of the fixing / isolating components.

[0009] Furthermore, the fastener is hexagonal prism and has a bolt hole that fits onto the bolt and engages with its thread. One end of the fastener has a connecting thread for connecting the fastener or the isolation component, the diameter of which is not less than the diameter of the bolt hole. The other end has a connecting nut that engages with the connecting thread.

[0010] Furthermore, the fastener is selectively provided with a plurality of fixing mechanisms distributed circumferentially on the outer surface of the fastener, and the fastener is fixed to the pre-embedded position of the bolt by the fixing mechanisms.

[0011] Furthermore, the fixing mechanism includes a horizontal bar disposed on the outer surface of the vertical fixing member and a vertical bar disposed at the end of the horizontal bar along the vertical direction.

[0012] Furthermore, the isolation component is cylindrical and has a through hole with an inner diameter matching the diameter of the bolt. One end of the isolation component has a connecting thread for connecting the fixing component or the isolation component, and the diameter of the connecting thread is not less than the diameter of the through hole. The other end has a connecting nut that mates with the connecting thread.

[0013] Furthermore, it also includes an anti-pull-out wing plate installed at the bottom of the adjustment assembly. The anti-pull-out wing plate includes a wing plate and a connecting part disposed at the center of the wing plate. The end of the connecting part away from the wing plate is provided with a connecting nut / connecting thread, and the end of the connecting part near the wing plate is provided with a bolt nut that mates with the bolt.

[0014] Furthermore, it also includes sealing cap I or sealing cap II for sealing the adjustment components during pouring.

[0015] Furthermore, the sealing cover I is made of a rigid material and includes a cover plate I and a connecting thread / connecting nut disposed on one side of the cover plate I. The cover plate I is hexagonal prism-shaped, and the sealing cover I and the fixing member or isolation member on the top of the adjusting assembly form a seal through threaded engagement.

[0016] Furthermore, the sealing cover II is made of flexible material and includes a cover plate II and a sealing plug disposed on one side of the cover plate II. The diameter of the sealing plug is the same as the diameter of the bolt. The sealing cover II is inserted into the fixing member or isolation member at the top of the adjusting assembly through the sealing plug to form a seal.

[0017] The beneficial effects of this utility model include:

[0018] (1) During installation, the fastener is equipped with a fixing mechanism, which makes it easier to connect with the steel bars. The fixing mechanism can be welded to the surrounding steel bars, which is more conducive to the accurate positioning of the pre-embedded bolt assembly. This makes the pre-embedded bolt assembly less likely to be disturbed during the pouring process, and the pre-embedded accuracy is higher.

[0019] (2) The adjustment components can be freely assembled, and the fasteners and isolation components can be added or reduced as needed. The appropriate number of fasteners and isolation components can be selected and freely assembled according to the pull-out force.

[0020] (3) The bolts are installed after being pre-embedded, so they are not easily deformed or damaged.

[0021] (4) When the bolts do not meet the requirements due to settlement or displacement, the bolts can be removed, an adjustment component can be added, the casting can be re-poured, and then the bolts can be reinstalled. Alternatively, the bolt length can be adjusted directly.

[0022] (5) When a bolt is damaged, it can be removed and replaced with a bolt of the same material. At the same time, when there is a need to change the bolt material, it can also be replaced with a bolt of other materials.

[0023] (6) Bolts can be recycled when they are no longer needed or when they are disassembled and moved, saving costs.

[0024] (7) An adjustable pre-embedded bolt assembly of the present invention can effectively reduce the cost of using pre-embedded bolts, reduce the difficulty of maintaining pre-embedded bolts, and reduce maintenance costs. Attached Figure Description

The adjustment assembly includes a fixing member 2 for fixing the embedded position of the bolt 1 and a separating member 3 for separating the poured concrete. The fixing member 2 and the separating member 3 are connected by threads. The bolt 1 passes through the adjustment assembly and is threadedly engaged with the fixing member 2 of the adjustment assembly. Figure 12 As shown, it includes a bolt 1 and an adjustment assembly mounted on the bolt 1. The adjustment assembly can be used to adjust the pre-embedded depth of the bolt 1 to meet the usage requirements of different application scenarios. The adjustment assembly includes several fixing parts 2 for fixing the pre-embedded position of the bolt 1 and isolation parts 3 for separating the poured concrete. Each fixing part 2 and isolation part 3 is connected by threads to form a bolt hole for mounting the bolt 1. The bolt 1 and the fixing parts 2 of the adjustment assembly are fixedly installed by thread engagement.

[0042] In this embodiment, the adjustment component can adjust the pre-embedded depth of the bolt 1 by increasing or decreasing the number of the fixing parts 2 / isolating parts 3. As shown in the figure, the adjustment component can adjust the number of the fixing parts 2 and isolating parts 3 that make up the adjustment component, that is, increase or decrease the number of fixing parts 2 / isolating parts 3, to achieve different depth requirements for the pre-embedded bolt 1. Alternatively, when the depth cannot meet the requirements, the number of fixing parts 2 / isolating parts 3 of the adjustment component can be increased, and then the casting can be carried out again to form a pre-embedded bolt hole that meets the depth requirements.

[0043] In this embodiment, the fixing member 2 is hexagonal prism and has a bolt hole that fits onto the bolt 1 and is threaded therewith. One end of the fixing member 2 has a connecting thread 7 for connecting the fixing member 2 or the spacer 3, the diameter of the connecting thread 7 being not less than the diameter of the bolt hole, and the other end has a connecting nut 8 that mates with the connecting thread 7; Figure 1 , 2 As shown in Figures 3 and 4, the fixing component 2 is a hexagonal prism similar to a nut, which makes it easy for construction workers to tighten the fixing component 2 with other components through threads using a matching wrench during assembly. It also has a bolt hole that fits onto the bolt 1 and engages with its thread for locking the bolt 1. It is also convenient to rotate and unscrew the bolt 1 for replacement when it needs to be replaced. At the same time, the two ends of the fixing component 2 are respectively provided with connecting threads 7 and connecting nuts 8 for connecting other components (such as fixing component 2 and isolation component 3), and the connecting threads 7 and connecting nuts 8 are matched in size, so that the adjustment component can be assembled in multiple ways.

[0044] In this embodiment, the fastener 2 is selectively provided with a plurality of fixing mechanisms circumferentially distributed on the outer surface of the fastener 2A, and the fastener 2A is fixed to the pre-embedded position of the bolt 1 by the fixing mechanisms; such as Figure 11 , 12 As shown in Figure 14, some fasteners 2A located near the reinforcing bar 10 are selectively provided with several fixing mechanisms for fixing the fasteners 2A in the pre-embedded position. The fixing mechanisms are distributed circumferentially along the outer surface of the fasteners 2A.

[0045] In this embodiment, the fixing mechanism includes a horizontal rod 201A disposed on the outer surface of the vertical fixing member 2A and a vertical rod 202A disposed at the end of the horizontal rod 201A along the vertical direction; as shown Figure 3 , 4 As shown in Figures 13 and 14, the fixing mechanism includes a horizontal rod 201A set on the outer surface of the vertical fixing member 2A and a vertical rod 202A set at the end of the horizontal rod 201A along the vertical direction. The lengths of the horizontal rod 201A and the vertical rod 202A are adjustable and can be adjusted according to the actual site conditions to ensure that the fixing mechanism can be connected to the surrounding steel bars 10 and fixed by welding or wire binding, so that the fixing member 2A is fixed in the pre-embedded position.

[0046] In this embodiment, the isolation member 3 is cylindrical and has a through hole with an inner diameter matching the diameter of the bolt. One end of the isolation member 3 has a connecting thread 7 for connecting the fixing member 2 or the isolation member 3, the diameter of the connecting thread 7 being not less than the diameter of the through hole. The other end has a connecting nut 8 that mates with the connecting thread 7. Figure 5 and 6As shown, the isolation piece 3 is cylindrical and has a through hole that matches the bolt 1 for the bolt 1 to pass through. One end of the isolation piece 3 is provided with a connecting thread 7 for connecting the fixing piece 2 or the isolation piece 3. The diameter of the connecting thread 7 is not less than the diameter of the through hole and does not affect the bolt 1 from passing through the isolation piece 3. The other end of the isolation piece 3 is provided with a connecting nut 8 that mates with the connecting thread 7. At the same time, the length of the isolation piece 3 can be in various sizes as needed. When the adjustment assembly is assembled, the pre-embedded depth can be adjusted by increasing the number of fixing pieces 2 / isolation pieces 3, or by selecting isolation pieces 3 of different lengths to adjust the pre-embedded depth.
