The demolding fixing base (5) is an assembly of a cone frustum and a cylinder, an axial thread blind hole which is the same as the thread of the screw rod is machined in the upper surface of the demolding fixing base, the screw rod (3) is in threaded connection with the demolding fixing base (5), the PVC pipe (2) is sleeved on the screw rod (3), and the PVC pipe (2) can be axially fixed by screwing the nut (1). The utility model discloses can make different series's fixing device according to the not equidimension reservation hole of concrete prefabricated component, the utility model discloses reuse rate is high, convenient operation, save engineering time, improved production efficiency. The utility model discloses an adopt drawing of patterns unable adjustment base to avoid the concrete prefabricated component drawing of patterns to lift by crane the influence that the concrete bonding that the in-process caused the component outward appearance destroyed, the screw rod uses the operating space who wipes face in having increased the production with the cooperation of nut.
Description
Technical Field
The utility model discloses a reserve hole fixing device that uses in the precast concrete component production process, specifically speaking are fixing device that is used for assembled precast concrete component to reserve hole.
Background
At present, in the production of an assembly type concrete prefabricated part, a reserved hole is generally fixed on a PVC pipe in a fixing tool, a magnetic base and other modes. The use of the above-described fixing means has the following drawbacks: due to oil stains and dust on the surface of the die table contacted with the magnetic base, after the magnetic base is used for several times, the magnetism of the magnetic base is weakened and is easy to move relative to the die table, so that the defects of inaccurate positioning, infirm fixation and the like of the reserved hole are caused; in addition, the manufacturing cost of the magnetic base is high, and the production cost of the concrete prefabricated part can be increased by using a large amount of the magnetic base. Simultaneously, still there are defects such as the surface unevenness that bonding concrete and cause during the prefabricated component drawing of patterns of concrete, and use fixed frock to influence workman's production operation, be unfavorable for later stage prefabricated component surface plastering.
Disclosure of Invention
In order to overcome the above-mentioned not enough that prior art exists, the utility model provides a fixing device for hole is reserved to assembled prefabricated component. The utility model discloses an adopt the unable adjustment base who has drawing of patterns angle and adjustable screw's combination, solved the assembled component and reserved the hole and led to the fact adverse effect's problem to component outward appearance and position accuracy, have and can satisfy multiple component and reserve advantages such as hole, construction easy and simple to handle and practice thrift manufacturing cost.
The utility model provides a fixing device for assembled concrete prefabricated component reserves hole, including drawing of patterns unable adjustment base, screw rod and nut, drawing of patterns unable adjustment base is the assembly of circular cone platform and cylinder, its upper surface processing with the same axial screw thread blind hole of screw rod screw thread, screw rod and drawing of patterns fixing base threaded connection, PVC pipe suit are in on the screw rod, the nut of screwing can make PVC tubular axial positioning, drawing of patterns unable adjustment base circular cone side and base plane's contained angle α become 60-80, the opening of two symmetries of drawing of patterns unable adjustment base's bottom processing.
Further, the demolding fixing base is fixed with the mold table through plug welding.
Furthermore, the demoulding fixed base, the screw rod and the screw cap are all made of common steel.
The utility model has the advantages that: the utility model can manufacture different series of fixing devices according to the reserved holes of the concrete prefabricated parts with different sizes, and is applied to the same reserved holes of the concrete members with different projects in a plug welding way, so that the repeated utilization rate is increased; the utility model adopts threaded connection except the welding of the demoulding fixed base and the mould platform, thereby facilitating the operation, saving the construction time and improving the production efficiency; the utility model discloses an adopt drawing of patterns unable adjustment base to avoid the concrete prefabricated component drawing of patterns to lift by crane the concrete bonding destruction that the in-process caused the component outward appearance, the screw rod uses the operating space who wipes face in having increased the production with the cooperation of nut.
Drawings
The present invention will be further explained with reference to the accompanying drawings.
FIG. 1 is a front view of a fixing device for prefabricated concrete prefabricated part hole reservation;
FIG. 2 is a front view of the stripper fixing base;
fig. 3 is a top view of the stripper shoe.
In the attached figure 1, 1-screw cap, 2-PVC pipe, 3-screw, 4-concrete, 5-demoulding fixed base and 6-mould table.
Detailed Description
The invention is described in further detail below with reference to the following detailed description and accompanying drawings:
a fixing device for prefabricated component hole of assembled is reserved, includes nut 1, screw rod 3 and 5 triplexes of drawing of patterns unable adjustment base, drawing of patterns unable adjustment base 5 is connected with screw rod 3, and screw rod 3 is connected with nut 1.
The screw cap 1, the screw rod 3 and the demoulding fixing base 5 are all made of No. 45 steel, the specification of the fixing device needs to be designed according to the diameter of a reserved hole of a concrete prefabricated part, and the angle a of the demoulding fixing base 5 is 65 degrees. In the production of the fabricated concrete prefabricated part, the fixing device is fixed on the mould table 6 firstly, and the procedures are as follows: firstly, after the position of a reserved hole is determined, two symmetrical notches are processed at the bottom of a demoulding fixing base 5 and are welded with a mould table 6 by using the reserved plug welding hole, a screw 3 is screwed into the demoulding fixing base 5 through screw threads after welding is finished, a PVC pipe 2 is sleeved into the screw 3, and finally a nut 1 is screwed to fix the PVC pipe 2 sleeved on the screw 3. And after the fixing device is installed, concrete is poured, after the pouring is finished and the strength of the fixing device reaches the strength required by the design, the screw cap 1 and the screw rod 3 are disassembled, finally, the concrete component is lifted, and the demolding fixing base 5 is left on the mold table 6 and is used for producing the next concrete prefabricated component continuously. If the position of the fixing device on the die table 6 needs to be changed, the welding point of the demoulding fixing base 5 is knocked off and then is welded to other positions.
