Description

TECHNICAL FIELD

[0001] The utility model relates to a plain concrete foundation pre -buried bolt hole mounting structure, concretely relates to a pre -buried bolt hole mounting structure suitable for monocrystal furnace and other large -volume plain concrete foundation, belongs to building engineering technical field. BACKGROUND

[0002] In prior art, the pre -buried bolt (hole) in industrial building is usually fixed in reinforced concrete structure, and positioning and fixing usually depend on the reinforcement in the structure, and there are few construction methods for fixing the pre -buried bolt hole in plain concrete. In actual construction, the pre -buried bolt hole is usually fixed in large -volume plain concrete by pouring plain concrete first, positioning by using plastic plate and other molds, and then implanting pipe fittings to form the pre -buried hole. There are the following problems:

[0003] 1) Many procedures, low efficiency. The plastic plate and other molds need to be cut according to the outer contour size of the large -volume plain concrete in advance, and the bolt hole position is calibrated and holed, then it is taken to the plain concrete foundation site for installation, and the size of the plain concrete foundation is usually larger than the mold size, which may involve splicing. If the positioning size changes, it needs to be recalibrated and cannot be reused.

[0004] 2) Material waste, cost increase. Since the concrete needs to be poured first and then the pipe fittings are pressed in, the excess scattered concrete will be discarded, and when there are many reserved holes, the cost of the discarded amount is particularly obvious. At the same time, the plastic plate is disposable.

[0005] 3) Large positioning error, affecting the quality of surface finishing. When the pipe fittings are pressed in, a protrusion will be formed near the excess concrete, and to finish the surface, the hole diameter will be larger than the outer diameter of the pipe fittings by more than 5-6 cm, and the protruding part of the concrete will overflow from this position, thereby affecting the surface finishing. In positioning, this part of the plane and the elevation positioning depend on the subjective sense of responsibility of workers, and at the same time, affected by the buoyancy, the pre -buried pipe fittings are easy to float up, thereby affecting the positioning elevation and subsequent equipment installation.

[0006] 4) Since the mold has a large contact area with the concrete, it needs to be cleaned in time when it is used repeatedly, which affects the service life, and also has the problems of inconvenience to carry, etc. UTILITY MODEL CONTENTS
