Description

An adjustable combined support frame for vertically supporting foundation anchor bolts

technical field

The utility model relates to the field of building construction, in particular to an adjustable combined support frame for vertically supporting foundation anchor bolts.

Background technique

Steel structures are known as "green buildings" for their light weight, high strength, and low environmental pollution; they are also known as "sustainable buildings" because of their high material recovery rate and convenient recycling. In recent years, with the continuous improvement of design level and construction technology, super high-rise steel structure has been developed rapidly. The section of the column foot member of this kind of steel structure is very large, and there are dozens or hundreds of anchor bolts used for each column foot, forming an anchor bolt group. Tens of kilograms to hundreds of kilograms, without any connection between each other.

The traditional anchor bolt construction technology of single installation and temporary fixing can no longer meet the needs of this anchor bolt form. Using anchor bolt support frame (formwork) to combine several anchor bolts in sequence and install them in place as a whole is the solution to the problem of anchor bolt group. A very efficient method of construction. However, the anchor bolt support frame adopted in the past has the following problems:

1. The anchor bolt support frame is placed directly on the steel bar on the top layer of the steel mesh; when there are people walking around, material stacking and displacement, and other construction processes, the steel bar will be deformed, causing the support frame to tilt, etc. disturbance, and the higher the support frame, the greater the disturbance. When the support frame is adjusted due to interference and deviation, due to the high elasticity of the steel bar, it needs to be adjusted many times, and the adjustment accuracy is also affected. Even if there is a slight inclination, the anchor bolt will be deformed because it cannot automatically correct the deviation. During the construction of complex-shaped foundation pits, the height and position cannot be adjusted arbitrarily, which is greatly restricted by the construction conditions on site.

2. The technical scheme of placing the anchor bolt support frame on the foundation cushion; its disadvantage is that the support frame is assembled in one piece on site, which is inefficient and difficult to adjust and position.

3. The improvement plan for the support frame to be placed on the foundation cushion; it is a method of presetting a number of independent columns on the foundation cushion, and then connecting several columns of the upper prefabricated support frame to one of them. This technical solution still has the problems of cumbersome positioning and installation. For example, the positioning accuracy of the independent column itself is high, and it is inconvenient to connect with the upper prefabricated support frame column one by one, and the welding volume is large; Due to the influence of net deformation, it needs to be reinforced again after adjustment, so it is very cumbersome.

The most important thing to control the installation accuracy of anchor bolts is to firstly control the distance between adjacent anchor bolts. It is necessary to ensure that the anchor bolts have the function of automatic deviation correction within a certain vertical deviation range, so as to ensure that the anchor bolts can pass through the base plate of the column base or the base plate of the steel plate wall smoothly. Bolt holes; the second is to control the axis deviation of the anchor bolts to ensure that the plane position of the base plate of the column foot or the steel plate wall bottom plate is accurate; the third is to ensure that the height of the anchor bolts is consistent and that all anchor bolts are evenly stressed. In addition, in the construction, it is necessary to be able to overcome the influence of other civil engineering processes such as steel bar binding, concrete pouring, accidental collision, etc. on the installation accuracy of anchor bolts.
