Abstract
The utility model provides a fixed embedded part of a lifting scaffolding, which comprises a base and a lead screw. At least three through holes are drilled and evenly distributed at the edge of the base. One end of the lead screw is perpendicular to the base and is welded in the middle of the base. The cross section of the lead screw is much less than the area of the base. Trapezoidal threads are arranged at the other end of the lead screw and a round column is arranged at the end. The round column is concentric with the lead screw and the cross section of the round column is less than the cross section of the lead screw. The utility model has the advantages of high safety and reliability, convenient operation and high economy and practicability.
Description
Technical field
The utility model belongs to the construction safety technical field, particularly relates to a kind of preburied component of reusable building operations attachment type raise scaffold.
Background technology
As shown in Figure 1, in the attachment type raise scaffold work progress, usually need the bracing frame that adheres to of attachment type raise scaffold is fixed on the horizontal reinforcement concrete structure plate 8, this adopts often on the bottom support template 6 of horizontal reinforcement concrete structure plate 8 service sleeve 13 vertically is set, when after concreting, reaching specified intensity, with screw rod 12 with the support shuttering 6 of horizontal reinforcement concrete structure plate 8 and its bottom and adhere to that bracing frame 9 threes penetrate and mode that pressing plate 10 and nut 11 by screw rod 12 two ends is clamped together fixes attachment type raise scaffold.
In the prior art, service sleeve 13 is often because of the fixing not firm positioning that occurs, tilt phenomenon, particularly because of the demoulding cycle in demoulding cycle of the bottom support template 6 of horizontal reinforcement concrete structure plate 8 much larger than vertical reinforcement concrete structure facade template, and three to four work floors generally lag behind, and the permission cover height of attachment type raise scaffold is five work floors, for the protection cover height that guarantees lifting false work meets the construction safety requirement, certainly will cause adhering to bracing frame 9 and must being fixed on the horizontal reinforcement concrete structure plate 8 of attachment type raise scaffold like this, and at this moment its bottom support template 6 does not also remove, can only adopt screw rod 12 with the support shuttering 6 of horizontal reinforcement concrete structure plate 8 and its bottom and adhere to that bracing frame 9 threes penetrate and mode that pressing plate 10 and nut 11 by screw rod 12 two ends are clamped together fixes attachment type raise scaffold, could remove Deng behind the horizontal reinforcement concrete structure plate Final 8 degree arrival design objective, clamped by the pressing plate 10 at screw rod 12 two ends and nut 11 owing to bottom support template 6 this moment, construct the phenomenon of the bottom support template 6 of plate 8 so the workman often occurs for removing the horizontal reinforcement concrete with pressing plate 10 and nut 11 dismountings, serious threat attachment type raise scaffold safe in utilization, the major safety risks that exist the dead group of group to hinder are badly in need of solving.
Summary of the invention
The purpose of this utility model is to provide in a kind of safe and reliable, easy to operate, economical and practical attachment type raise scaffold in order to fixedly to adhere to the preburied component of bracing frame.
For addressing the above problem, the fixedly built-in fitting of a kind of lifting false work that the utility model provides, comprise base 1, screw mandrel 2, the edge of described base 1 is drilled with equally distributed at least three through holes 3, one end vertical center of screw mandrel 2 be welded on the base 1 and the bar cross section of described screw mandrel 2 much smaller than the plane of base 1, the other end of described screw mandrel 2 is provided with trapezoidal thread 5 and this end end and is processed with concentric and less than the circular column cap 4 in screw mandrel 2 bar cross sections with screw mandrel 2.
Described base 1 is square or rectangle preferably.
The utility model provides a kind of preburied component that bracing frame is fixed that adheres to of attachment type raise scaffold, the utility model compared with prior art has the following advantages: one, because by base 1, screw mandrel 2, through hole 3, the built-in fitting that circular column cap 4 and trapezoidal thread 5 are formed is embedded in the top of the bottom support template 6 of horizontal reinforcement concrete structure plate 8, can not clamp the bottom support template 6 of horizontal reinforcement concrete structure plate 8 during use, stopped workman's fixing screw rod 12 of lifting false work when removing the bottom support template 6 of horizontal reinforcement concrete structure plate 8, pressing plate 10, the appearance of major safety risks has thoroughly been eradicated in the great operation against rules that nut 11 is removed on the technical measures of product.They are two years old, owing to be drilled with at least three through holes 3 on the base 1, at least three common iron nails easy to use will be by fixedly securing on the bottom support template 6 of horizontal reinforcement concrete structure plate 8 that base 1, screw mandrel 2, through hole 3, round end column cap 4 are formed, effectively avoided the positioning of preburied component, avoid the appearance of doing over again, improved construction efficiency.They are three years old; because base 1, screw mandrel 2 are the firmly integral body of welding; significantly reduced because of bolt assembly scattered and volume less cause lose phenomenon; simultaneously owing to have the end of trapezoidal thread 5 to be processed with, coenosarc 2 concentric on the screw mandrel 2 and less than the circular column cap 4 in screw mandrel 2 bar cross sections with screw mandrel; trapezoidal thread 5 with protection screw mandrel 2 tops is not damaged when preburied component is removed in hammering downwards; prolonged the reusable number of times of preburied component; reduced the overlapping investment of member; reduce cost, improved economic benefit.
The utlity model has safe and reliable, easy to operate, economical and practical characteristics.

Number description:
The specific embodiment
In conjunction with the accompanying drawings 2,3, be elaborated in order to the preburied component that fixedly adheres to bracing frame in a kind of safe and reliable, easy to operate, the economical and practical attachment type raise scaffold that the utility model is provided:
As shown in Figure 2, after bottom support template 6 constructions of horizontal reinforcement concrete structure plate 8 finish, hammer in the through hole 3 with 4 iron nails, the assigned address that adheres to bracing frame 9 of lifting false work is installed at needs, will be by base 1, screw mandrel 2, through hole 3, the preburied component that round end column cap 4 and trapezoidal thread 5 are formed fixedly secures on the bottom support template 6 of horizontal reinforcement concrete structure plate 8, the trapezoidal thread 5 that has wrapped up screw mandrel 2 upper ends with plastic sheeting pollutes to prevent concrete, by the time the concreting of horizontal reinforcement concrete structure plate 8 finish reach specified intensity after, remove the parcel plastic sheeting of screw mandrel 2 upper end trapezoidal threads 5, what be inserted in lifting false work earlier adheres to bracing frame 9, be inserted in pressing plate 10 again, fastening nut 11, by by base 1, screw mandrel 2, through hole 3, the preburied component that round end column cap 4 and trapezoidal thread are 5 one-tenth is with horizontal reinforcement concrete structure plate 8, adhere to bracing frame 9 and firmly be tightened in together, reach the purpose that the utility model provides.
