Embodiment Construction

[0010] Such as figure 1 As shown, the construction method for adjusting the steel plate embedded parts to achieve the design and construction accuracy of the present invention is: when installing each embedded steel plate 1, the lower surface of the embedded steel plate with the embedded steel plate anchor bar 2 is close to 4 right angles Weld four screw rods 4 at the bottom of the right angle. Each screw rod is first screwed into the leveling nut 5, and then penetrated into the sleeve 6. The sleeve 6 is welded to the fixed steel bar 3 through the sleeve fixed steel plate 7. Each screw is used The sleeve fixing steel bar 3 used to fix the sleeve is placed directly below the right angle of the position where the embedded steel plate is installed. The sleeve fixing steel bar is anchored on the base surface before the embedded steel plate is installed. Measure and adjust each leveling nut so that the The elevation of the top surface of the buried steel plate and the accuracy of t...

Abstract

The invention relates to a construction method for adjusting steel plate embedded parts to reach design and construction accuracy. The construction method comprises following steps: welding four screw rods in the vicinity of four right-angle positions under a pre-embedded steel plate having a pre-embedded steel plate anchor bar when each pre-embedded steel plate is installed; first screwing leveling nuts to each rotary screw rod and penetrating into sleeves; welding sleeves with sleeve fixation rebars; anchoring sleeve fixation rebars to a fundamental plane prior to installation of the pre-embedded steel plate; measuring and adjusting each leveling nut such that the elevation of top surface and horizontal plane accuracy of the pre-embedded steel plate satisfy the design requirement; and ultimately, screwing clamp nuts and fixing the pre-embedded steel plate in order to prevent the pre-embedded steel plate from being lifted by uplift pressure of concrete during the process of pouring foundation concrete. The construction method for adjusting the steel plate embedded parts to reach design and construction accuracy has following beneficial effects: when hole opening operation is not conveniently performed for the pre-embedded steel plate and no installation and leveling device is available, the method and a device are easy and practical; operation is performed easily; and easy operation, high installation accuracy and efficiency are obtained.

Description

technical field [0001] The invention belongs to the technical field of engineering construction, in particular to a construction method for adjusting steel plate embedded parts to achieve design and construction accuracy. Background technique [0002] In engineering construction, in order to meet the needs of later equipment installation, steel plates are often pre-embedded in poured concrete. The installation accuracy of steel plate embedded parts is directly related to whether the later equipment can be successfully installed. If the installation accuracy of steel plate embedded parts does not meet the requirements, the adjustment is very Difficult, it is generally necessary to chisel out the concrete, adjust the precision of the embedded parts and then pour the concrete again, which not only increases the construction cost, but also prolongs the construction period, which directly affects the on-schedule operation of the equipment. [0003] The biggest difficulty in the i...
