Abstract
A kind of pre-buried support of derrick crane lower margin of the present invention belongs to Architectural Equipment field, overcome in traditional tower crane ground and pre-embedded bolt process of construction and simply simply use horizon rule and tape measure, positioning to the level and pre-embedded bolt of ground operates, it is unhorizontal to easily cause terrace, Bolt sizes are not accurate, tower crane has tilt phenomenon after installing, and causes potential safety hazard.Solves the support that the former deficiency has invented tower crane foundation ditch terrace level and pre-embedded bolt positioning, bolt is positioned using horizontal and vertical punching block standard size bolt hole, put down over the ground equipped with high-accuracy water level on horizontal and vertical punching block and carry out horizontal detection, it is ensured that tower crane installs perpendicular to the ground.
Description
Technical field
A kind of pre-buried support of derrick crane lower margin of the present invention belongs to Architectural Equipment field, and more particularly to terrace is horizontal when mounted and pre-embedded bolt accurate positioning for tower crane.
Background technology
Simply simply horizon rule and tape measure are used in traditional tower crane ground and pre-embedded bolt work progress, the level of ground and the positioning of pre-embedded bolt are operated, easily cause that terrace is not horizontal, and Bolt sizes are not accurate, tower crane has tilt phenomenon after installing, and causes potential safety hazard.
Patent of invention content
A kind of pre-buried support of derrick crane lower margin of the present invention, overcome in traditional tower crane ground and pre-embedded bolt process of construction and simply simply use horizon rule and tape measure, positioning to the level and pre-embedded bolt of ground operates, it is unhorizontal to easily cause terrace, Bolt sizes are not accurate, tower crane has tilt phenomenon after installing, and causes potential safety hazard.Solves the support that the former deficiency has invented tower crane foundation ditch terrace level and pre-embedded bolt positioning, bolt is positioned using horizontal and vertical punching block standard size bolt hole, put down over the ground equipped with high-accuracy water level on horizontal and vertical punching block and carry out horizontal detection, it is ensured that tower crane installs perpendicular to the ground.
Present invention is achieved through the following technical solutions：
A kind of pre-buried support of derrick crane lower margin：Longitudinal punching block 1, horizontal punching block 2, bolt positioning punching block 3, pre-embedded bolt 4, lateral level 5, vertical equity instrument 6, center fixing bolt 7 can be divided into, longitudinal punching block 1 is connected by center fixing bolt 7 with horizontal punching block 2, bolt positioning punching block 3 is respectively arranged in the both ends of longitudinal punching block 1 and horizontal punching block 2, pre-embedded bolt 4 is connected with bolt positioning punching block 3, lateral level 5 is installed on the centre position of horizontal punching block 2, and vertical equity instrument 6 is installed on the centre position of longitudinal punching block 1.
Brief description of the drawings
Fig. 1 is a kind of pre-buried support front view of derrick crane lower margin：
Embodiment
Further illustrate how the present invention is implemented in conjunction with accompanying drawing 1：
A kind of pre-buried support of derrick crane lower margin：Longitudinal punching block, horizontal punching block, bolt positioning punching block, pre-embedded bolt, lateral level, vertical equity instrument, center fixing bolt can be divided into, longitudinal punching block is connected by center fixing bolt with horizontal punching block, bolt positioning punching block is respectively arranged in the both ends of longitudinal punching block and horizontal punching block, pre-embedded bolt is connected with bolt positioning punching block, lateral level is installed on the centre position of horizontal punching block, and vertical equity instrument is installed on the centre position of longitudinal punching block.
A kind of pre-buried support of derrick crane lower margin of the present invention is in use,First foundation ditch is dug to defined standard,The concrete poured into again to foundation ditch,The bolt positioning punching block of the pre-embedded bolt supporting with tower crane base and horizontal location support is sequentially connected and installed,The bottom surface of horizontal stand is painted into releasing agent,Pre-embedded bolt and horizontal location support are integrally put into foundation ditch,The one of pre-embedded bolt band hook is upside down,The one side of horizontal location supporting band level meter is upward,Bottom surface and ground keep level of the vertical equity support with transverse horizontal support,It is defined by horizontal pointer,And it is suspended on foundation ditch center,Foundation ditch concrete is filled up,Vibratory concrete is reached into dense effect with vibrating head,And the horizontal and vertical level of horizontal stand is adjusted by level meter,Make being intimately associated for concrete and horizontal stand bottom surface,After treating 120 hours,Unload horizontal location support,Can construction and installation tower crane.
