Abstract

The utility model relates to a popular concrete round hole slab, belonging to a member for buildings. The utility model is characterized in that a bottom die and side dies are welded into integration and are fixedly embedded in the semi round of a turnover frame, grooves are arranged on end dies, and pull hooks and screw threads are respectively arranged on two fixed square steels welded on the inner walls of the two side dies and arranged on the outer sides of the end dies. The utility model has small vibration, no crack to the member, high member quality, small investment, convenient use and easy popularization and use and ensures the positions of steel bars in concrete.

Description

Popular concrete circular hole slab

The utility model relates to a kind of popular concrete circular hole slab, belongs to the building member class.

At present, produce the non-concrete circular hole slab of answering in advance, main with the upset mould." the 455th page of practical concreter's handbook 1993 the 9th phase of publishing as: Shanghai Communications University, the wooden model of its disclosed concrete circular hole slab is to be placed on the rollover stand after assembled by side form, bed die, end mould, fix with timber wedge, this kind constructional device weak point: one, vibration is too big when upset, can be static immediately beyond side form lands earlier, and the another side of side form and rollover stand are fixed with timber wedge, loosely organized, speed during with upset also will travel forward because of inertia, very easily cause structure member crevices, component quality is reduced.Two, the cloth reinforcing bar position is very limited in the concrete core slab, and the net sheet muscle in the member can not be fixed, and has understood living displacement in smashing the process of shaking, and does not reach protective layer, and component quality can not guarantee.

The purpose of this utility model is to provide a kind of minimizing upset vibration, mold integral strong, not only can make component surface smooth smooth, free from flaw, and also it is accurate to make component inside lay reinforcing bar, it is convenient promptly to use, and can guarantee a kind of popular concrete circular hole slab of component quality again.

The purpose of this utility model is achieved in that

The utility model includes rollover stand, bed die, side form, end mould, it is characterized in that: bed die, side form are welded as a whole, and in the semicircle of fixedly embedded rollover stand, the end mould inserts in dovetail groove, and have groove in the top, and fixedly square steel is welded in the outside, end mould two ends respectively, and one fixedly has the hole on the square steel, the buckle screw thread is housed in the hole, and another fixedly is welded with pull hook on the square steel.

Fixedly the screw thread on the square steel and fixedly the hook on the square steel and net sheet muscle on same plane, and corresponding with the groove on the end mould.

The utility model is owing to be fixed as one side form and bed die, and be embedded in the semicircle of rollover stand, mould reduces the height of a thickness of slab, vibrate when having reduced upset, owing to whole device is fixed as one, after rollover stand lands, inertia during along with upset can move together with static, so the crack does not appear in member, has guaranteed component quality, and easy to use.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the front view of the utility model end mould.

The utility model bed die 2, side form 3 be welded as a whole the back fixedly embedded rollover stand 1 semicircle in, end mould 4 inserts in dovetail groove, and have groove 8 in the top, fixedly square steel 5,7 welds with two side forms, 3 inwalls respectively, and be individually fixed in two ends mould 4 outsides, fixedly have the hole on the square steel 5, buckle screw thread 9 is housed in the hole, fixedly be welded with pull hook on the square steel 7.When using the utility model, the equal heart of a small amount of concrete is layered on the bed die 2, behind the punching pipe, puts into bar-mat reinforcement after repaving an amount of concrete, after being placed on two ends on the reinforcing bar in the end die cavity 8 respectively, one end bar is connected with pull hook 6, and other end reinforcing bar is with after screw thread 9 is connected, after regulating screw thread 9 and fixing reinforcing bar, concrete casting is poured in the template, water foot back and smash with plate vibrator and shake, until smash shake closely knit, till trimming.Smashing shakes finish after, rollover stand 1 upset is landed for 180 °, take out the tube core mould unloading.
