Background
If the vertical component of the fabricated concrete frame structure adopts a prefabricated building mode, prefabrication can be carried out from positive and negative zeros. The prefabrication splitting mode and the construction process necessarily relate to the conversion position from the cast-in-place foundation to the connection of the prefabricated columns on the first floor, namely the conversion from the cast-in-place to the prefabrication. The traditional method for converting the position of the assembly type frame structure is characterized in that a sleeve grouting connection technology is adopted, a prefabricated column longitudinal inserting rib is reserved on a cast-in-place foundation, a grouting sleeve is pre-buried at the bottom of the prefabricated column during production, then the prefabricated column is hoisted on site, the inserting rib of the cast-in-place foundation is inserted into the sleeve at the bottom of the prefabricated column, and finally sleeve grouting operation is carried out to realize the construction connection from the cast-in-place to the prefabricated converting position. However, there are many disadvantages to this conventional process:
(1) the embedded positioning error of the joint bars during the construction of the cast-in-place foundation is large, the position of a bottom grouting sleeve and the position of the embedded joint bars possibly have large deviation when the prefabricated column is hoisted, the hoisting of the prefabricated column is affected to be in place, the bending adjustment of the joint bars generally exists in a construction site, and the joint bars are broken off seriously;
(2) the sleeve grouting construction process quality is greatly influenced by personnel and environment, hidden dangers exist in the construction quality, the quality detection means is immature, and simple and rapid nondestructive detection cannot be realized.
Aiming at the situation, the connection between the first-layer prefabricated column of the assembly type concrete frame structure and the cast-in-place foundation at the present stage begins to adopt a cup-mouth foundation form, namely, the cast-in-place foundation adopts the cup-mouth foundation, the bottom of the prefabricated column is not embedded with a grouting sleeve, the prefabricated column is hoisted in place to the cast-in-place cup-mouth foundation during field construction, and then fine stone concrete is poured into the cup mouth to realize the connection between the prefabricated and the cast-in-place foundation after the verticality is adjusted and temporarily fixed. This connected mode can avoid because of cast in situ concrete construction error is great, the unable problem of installing of prefabricated post. But the connected form of prefabricated post rim of a cup basis also has several shortcomings, and it is comparatively difficult mainly that the location of prefabricated post for the axis position, the wooden wedge of processing scaling-off is generally adopted when traditional rim of a cup basis post hoists to take one's place, and the post hoists to take one's place the back and is squeezed into the wooden wedge all around and fix the post and adjust the straightness that hangs down, but this kind of mode is loaded down with trivial details and the wooden wedge can not reuse, and relative hoist installation effectiveness is lower.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the utility model provides a but provides a quick installation positioner of prefabricated post for rim of a cup basis specially, the device reuse, the simple and fast realization of while is prefabricated the post location in the rim of a cup basis, improves the efficiency of construction.
In order to achieve the above purpose, the utility model provides a technical scheme as follows:
a prefabricated column rapid mounting and positioning device for a cup rim foundation comprises an upper layer positioning frame and a lower layer positioning frame, wherein rectangular holes are formed in the upper layer positioning frame and the lower layer positioning frame; the four corners of the upper positioning frame and the lower positioning frame are fixedly connected through angle steels; the upper layer positioning frame and the lower layer positioning frame are formed by butting two sub-frames; the outer portions of the two sub-frames of the lower-layer positioning frame are provided with a section of outwards-extending channel steel plate with a scribing line and a size, and screw through holes are formed in the channel steel plate.

FIG. 1 is a top view of a precast column quick mount positioning device;
fig. 2 is a schematic view of the positioning device mounted at the cup opening device.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Examples
Shown in fig. 1 is a precast column rapid installation positioning device, which is installed on a cup foundation 70 and comprises an upper layer positioning frame 10 and a lower layer positioning frame 20, wherein rectangular holes 30 are respectively arranged in the upper layer positioning frame 10 and the lower layer positioning frame 20, and the size of the rectangular hole 30 is matched with that of a precast column. The four corners of the upper positioning frame 10 and the lower positioning frame 20 are fixedly connected through angle steel 40, so as to ensure the perpendicularity of the prefabricated column by utilizing the upper and lower positioning frames 20. Preferably, the angle iron 40 is fixed between the upper positioning frame 10 and the lower positioning frame 20 by a welding process.
