How to bury the hole of the anchor bolt is explained in detail

The anchor bolt reserved hole is generally divided into 4 processes:

1. Verticality of anchor boltsWhen installing anchor bolts, they should be vertical and not tilted. 2. The laying of anchor bolts in the process of anchor bolt installation, what is often encountered is the secondary grouting of dead anchor bolts, that is, when pouring the foundation, leave the reserved holes of anchor bolts on the foundation in advance, wear anchor bolts when installing equipment, and then use concrete or cement mortar to pour the anchor bolts to death. 3. Anchor bolt installation - tightening.

4. Do a good job in the construction records of the installation of the anchor bolts, and the corresponding construction records should be made in detail during the installation of the anchor bolts, and the models and specifications of the anchor bolts should be truly reflected, so as to provide effective technical information for future maintenance and replacement. Generally, the embedded with high installation accuracy must be made into a ground cage first (it needs to be worn on the embedded steel plate with bolt holes first, and the nut is installed and pressed. Before pouring, the embedded parts are tied to the template and fixed, so that the installation size of the foot bolts can be guaranteed.

If you want to save materials, you can also use steel bar welding to fix, and the geometric dimensions need to be calibrated after the welding is completed. At this point, the installation of the foot bolts is truly completed.

Hello, anchor bolt reserved hole burial method, also known as reserved hole method, secondary grouting buried anchor bolts. The anchor bolt hole is a very important part of the equipment installation. Anchor bolts are installed in the holes, corrected, and fixed with fine stone concrete or non-shrinkage fine stone concrete secondary grouting .

Although this method has low precision requirements (20mm) for reserved holes, simple construction technology, no fixed frame, and steel saving. Hope it helps, thank you.

Summary. 3. Embed the bolt group into the short column in advance, insert it into the reserved hole, and then weld it with the foundation beam to weld it firmly.

How to bury the hole of the anchor bolt is explained in detail

1. Carry out the wiring elevation according to the scheme to ensure that the horizontal position and elevation are correct.

2. Determine the height of the steel plate, position the formwork, you can start pouring concrete, and do not let the corner bolt shift when pouring concrete.

3. Embed the bolt group into the short column in advance, insert it into the reserved hole, and then weld it with the foundation beam to weld it firmly.

In the construction process, we basically need to use steel materials for construction, when we choose steel materials, we must pay attention to the quality of raw materials, to ensure that the quality of raw materials are clear, the quantity is together, can not cut corners, in order to return to enough to build a qualified construction project.

Steel structure anchor bolt embedding is a common way to fix the steel structure, the purpose of which is to bury the bolt into the concrete base to make it fixed on the base, so as to ensure the stability and safety of the building. The method of embedding steel structure anchor bolts is roughly divided into the following steps:

The first step is to make a pre-buried pit for the snail and hail bolts, and the shape and size of the pit should match the size of the bolts. At the bottom of the embedded pit, a layer of bottom cushion with a thickness of 10 20mm is laid so that the bolt can be evenly stressed.

The second step is to install the bolts, insert the pre-made bolts into the embedded pit, the position of the bolts needs to be accurate, and a certain gap needs to be maintained between the bolts and the embedded pit, so that the concrete can flow around the bolts.

The third step is to fix the bolts in the pit with plastic ropes or wooden poles to ensure that the bolts do not move or tilt when pouring concrete.

The fourth step is to pour concrete, pour concrete into the embedded pit, the concrete should evenly fill the entire embedded pit, and when filling the concrete, you also need to tap the bolts with a hammer to exclude air and loose concrete.

Finally, after waiting for the concrete to be fixed, the bolts can be lifted or locked.

The above is the basic steps of steel structure anchor bolt embedding, which effectively prevents the bolt from loosening or falling off, and improves the safety factor and stability of the building.

Summary. When the anchor bolt is not buried, we can take the following ways to solve it:1

Use expansion bolts: Insert the expansion bolt into the hole of the anchor bolt and rotate it with a wrench or wrench to make the bolt expand and fix in the concrete. 2.

Use a chemical anchor: Pour the chemical anchor into the anchor bolt hole, insert the bolt and rotate, wait for a while until the chemical anchor is fully cured, and the installation is ready to go. 3.

Use mechanical anchors: Use mechanical anchors, such as mechanical expansion anchors or mechanical clamps, to secure the bolts inside the holes. The above are some of the solutions I know about, I hope it can help you.

When the anchor bolt is not embedded, we can take the following ways to solve the problem: 1Use expansion bolts:

Hello, what are the details of the use of anchor bolts embedded in construction projects?

The quality of the embedded parts of the anchor bolt will affect the installation quality of the steel structure building, so we must master and control the position, verticality, length and elevation of the anchor bolt, so that the reaming and adjustment workload can be reduced, and the rework can also be prevented, so that the quality of steel structure installation can be improved. The anchor bolt embedding method here can take the direct pre-embedding method, or the reserved hole method. It should be emphasized here that the supervision engineer must strictly check the rationality and reliability of the construction method of the embedded bolt before pouring the foundation concrete, and whether the measured indicators are within the scope of the standard rules.

If the equipment is installed on a concrete beam, its anchor bolts are generally embedded. If the equipment foundation has other special requirements, it can also be embedded in the concrete beam through the civil engineering profession to facilitate the penetration of anchor bolts. The size of the casing here should be at least 10mm between the anchor bolt and the casing, so that the bolt position can be adjusted, sand filling and tamping during equipment installation.

Hope it helps, thank you.

Hello, anchor bolts are very important in the preliminary work of steel structure engineering. Doing this well will greatly shorten the construction period, as well as improve and ensure the quality of construction. Before construction, the specifications of anchor bolts and the positioning of the steel plate are prepared in advance, in addition to the pre-check of the anchor bolt related indicators, but also in each piece of positioning anchor bolt steel plate pre-carved positioning measurement of the crosshair.

It is also necessary to observe and record the positions of the x-axis and y-axis according to the theodolite. Based on the hole centerline of the anchor bolt for positioning, it is reasonably calculated that the corresponding cross line needs to be carved on the positioning steel plate, and carved out on the positioning plate with a hacksaw.

Another more important preparatory work is to weld the anchor bolt on each foundation column pier in advance with the steel bar of diameter 6, and the advantage of this is that the relative position of the anchor bolt can be determined, play the role of positioning. For example, if there are two anchor bolts, we use two positioning steel plates to cover the ends of the two anchor bolts, and then place the anchor bolt heads down on the horizontal, hard ground.

The other end positioning steel plate is welded with two anchor bolts with 6 steel bars, and then the screw buckle end positioning steel plate is pulled out. The outer end of the turning end positioning steel plate is drawn to this end of the bolt, after placing the anchor bolt, the second 6 steel bar should be welded on this positioning steel plate, and this steel bar is required to be able to be poured in concrete. Finally, the steel plate used for positioning is pulled out.

After the welding is completed, it is necessary to check whether the top of the 4 anchor bolts is on a plane and whether the relative position is correct. Hope it helps, thank you.

Hello, how to reserve the bolt hole of the anchor bolt?

This process is a very important part of the whole installation anchor bolt project. This process looks very simple, but it has a wide range of applications. The anchor bolt reserved hole generally uses the embedded easy-to-pull wooden plug and steel bar to realize the reserved anchor bolt hole, this method is very simple, but there will be a very bad problem, sometimes the loosening of the anchor bolt will directly affect the use of the entire anchor bolt.

The second method is the method of adopting the pull-out plug body structure, and the pre-embedding method of this anchor bolt reserved hole will greatly reduce the damage rate of the anchor bolt. This makes it easy to remove the entire plug and strengthens the adhesion between the anchor bolt and the foundation. Another method is to use a pre-embedded plug body construction method.

This method can save the process of removing the plug body and greatly reduce the consumption of materials, which can ensure the quality and improve the efficiency to the greatest extent. In the installation of equipment anchor bolts often need anchor bolt reserved holes, generally required reserved hole section greater than or equal to 175 mm times 175 mm such a size, embedded depth to be greater than 1,000 mm of reserved hole depth. Hope it helps, thank you.
