Abstract
The invention discloses a method and a device for hole forming of reserved group bolt holes. The method comprises the following steps of 1, determining the size of a cantilever steel beam, and manufacturing a shaped hole forming device of the group bolt holes according to the size; 2, when the floor structure with steel beam anchoring is constructed, embedding the shaped hole forming device of the group bolt holes into a concrete slab; 3, before slab concrete is finally cured, plugging out the shaped hole forming device of the group bolt holes, so as to form the reserved holes. By adopting the technical scheme, the setting of the reserved holes is convenient, the relative position of the four bolt holes can be conveniently controlled, and the safety and reliability of subsequent steel beam anchoring are ensured.
Description
Technical field
The present invention relates to the realm of building construction, be specifically related to hole forming method and the device in a kind of reserved Bolt hole.
Background technology
The girder steel anchoring of existing builder's jack, adopts the method for bolt anchoring conventionally, and generally two anchor points need to be established in overhanging type steel end, i.e. four bolts hole.When floor concrete casting, bolt hole need to be reserved, but in work progress, the relative positioning of bolt hole is not easy to control, and causes follow-up girder steel anchoring not firm.Therefore need to adopt effective method, the relative position in reserved Bolt hole is met the requirements.
Summary of the invention
The deficiency existing for prior art, the object of the present invention is to provide a kind of easy to operately, can effectively control the relative position of four bolts hole, guarantees hole forming method and the device in the safe and reliable reserved Bolt hole of follow-up girder steel anchoring.
For achieving the above object, the invention provides following technical scheme: the hole forming method in a kind of reserved Bolt hole, comprises the following steps:
Step 1: determine the size of cantilever steel girder, and make regularization Bolt hole hole-forming device by this;
Step 2: during the construction of girder steel anchoring place floor structure, regularization Bolt hole hole-forming device is embedded in concrete floor;
Step 3; Before floorslab concrete final set, regularization Bolt hole hole-forming device is extracted, formed preformed hole.
By adopting technique scheme, preformed hole arranges conveniently, can effectively control the relative position of four bolts hole, guarantees the safe and reliable of follow-up girder steel anchoring.
The present invention is further set to: described regularization Bolt hole hole-forming device comprises rectangle framework, and four corner position places of described rectangle framework are fixedly installed four feets, described each feet respectively with vertical setting the in rectangle framework lower surface.By this setting, regularization Bolt hole hole-forming device is simple in structure, and cost is low, and reliable operation is easy to operate.
The present invention is also further set to: described four feet length and equal diameters.By this setting, the hole-forming device structure setting of regularization Bolt hole is more reasonable.
The present invention is also further set to: described four feets are all fixed by welding and rectangle framework lower surface.By this setting, each feet is connected reliably with rectangle framework.
The present invention is also further set to: the upper surface of described rectangle framework and lower surface are smooth plane.By this setting, rectangle frame body structure arranges rationally, makes work of the present invention more reliable.
Advantage of the present invention is: regularization Bolt of the present invention hole hole-forming device structure arranges rationally, adopts four contour feets of rectangle framework and lower surface welding thereof, and simple in structure, pore-forming is easy to operate.The relative position that can effectively control four bolts hole, guarantees the safe and reliable of follow-up girder steel anchoring.
Below in conjunction with specification drawings and specific embodiments, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present invention regularization Bolt hole hole-forming device.
The specific embodiment
Referring to Fig. 1, the hole forming method in a kind of reserved Bolt provided by the invention hole, is characterized in that: comprise the following steps:
Step 1: determine the size of cantilever steel girder, and make regularization Bolt hole hole-forming device by this;
Step 2: during the construction of girder steel anchoring place floor structure, regularization Bolt hole hole-forming device is embedded in concrete floor;
Step 3; Before floorslab concrete final set, regularization Bolt hole hole-forming device is extracted, formed preformed hole.
As preferably, the regularization Bolt hole hole-forming device described in the present embodiment comprises rectangle framework 1, and 1 four corner position places of described rectangle framework are fixedly installed four feets 2, described each feet 2 respectively with vertical setting the in rectangle framework 1 lower surface.
For making work of the present invention more reliable, easy to operate, as preferably, four feet 2 length described in the present embodiment and equal diameters.Described four feets 2 are all fixed by welding and rectangle framework 1 lower surface.
The upper surface of described rectangle framework 1 and lower surface are smooth plane.
The present invention can control the relative position of four bolts hole effectively, guarantees the safe and reliable of follow-up girder steel anchoring.
Above-described embodiment is to specific descriptions of the present invention; only be used to further illustrate the present invention; can not be interpreted as limiting the scope of the present invention, within the technician of this area makes some nonessential improvement according to the content of foregoing invention to the present invention and adjusts and all to fall into protection scope of the present invention.
