Abstract

Disclosed is a mould removing clamp for a reserved bolt hole reinforcing mould. The mould removing clamp for the reserved bolt hole reinforcing mould comprises a left clamping handle and a right clamping handle which are hinged to each other through a pin shaft, a half clamping sleeve is respectively arranged at lower ends of the left clamping handle and the right clamping handle, each half clamping sleeve comprises an L-shaped sleeve body and clamping teeth, the clamping teeth are arranged on inner side surfaces of the L-shaped sleeve body, and a square is defined by the two half clamping sleeves. The mould removing clamp for the reserved bolt hole reinforcing mould has the advantages that the structure is simple, the operation is simple and convenient, during usage, a chain block is installed in a hanging hole, half clamping sleeves surround a square wood reinforcing mould, and a reserved bolt core is arranged on one side of the square wood reinforcing mould; the chain block is upwards lifted so that the half clamping sleeves clamp the square wood reinforcing mould through the clamping teeth; the chain block is upwards pulled through a hoisting device till the square wood reinforcing mould is completely pulled out of the reserved bolt hole, the labor intensity of workers can be greatly reduced, the mould removing efficiency is increased, and the mould removing clamp is safe and reliable.

Description

A kind of prepared screw-bolt hole adds solid model form removal fixture

Technical field

The utility model belongs to withdrawing pattern clamp technology field, and particularly a kind of prepared screw-bolt hole adds solid model form removal fixture.

Background technology

In architectural engineering, large equipment base plane geometry size is larger, base shape complexity, and basic end face absolute altitude is more, and pre-embedded anchoring bolts and pre-embedded bolt hole number are huge.In concrete pouring construction, in order to ensure the quality of prepared screw-bolt hole, can reserved bolt fuse one side arrange the lumps of wood reinforce mould, often occur the lumps of wood add solid model be extruded be out of shape or because extracting the phenomenon of can not pulling out not in time after building.At present, for said circumstances, adopt more way to be: use pneumatic pick, electric drill that the lumps of wood is added to solid model and pulverize, then chip is drawn out gradually, labour intensity is large, and operating efficiency is low, the particularly larger prepared screw-bolt hole of some degree of depth, form removal difficulty is larger.

Utility model content

The purpose of this utility model is to provide a kind of simple in structure, easy and simple to handle and safe and reliable prepared screw-bolt hole and adds solid model form removal fixture.

For achieving the above object, the technical solution of the utility model is: a kind of prepared screw-bolt hole adds solid model form removal fixture, comprise the left clamp holder and the right clamp holder that are hinged by bearing pin, left clamp holder and right clamp holder lower end are respectively equipped with half chuck, half chuck comprises the clamping tooth on L shaped body and L shaped body medial surface, and it is square that two halves chuck encloses formation.

Described left clamp holder and right clamp holder upper end offer lifting hole(eyelet).

Described clamping tooth is perpendicular to the L shaped body medial surface at place.

Compared with prior art, the utility model has the advantages that:

1, the utility model comprises the left clamp holder and the right clamp holder that are hinged by bearing pin, left clamp holder and right clamp holder lower end are respectively equipped with half chuck, half chuck comprises the clamping tooth on L shaped body and L shaped body medial surface, it is square that two halves chuck encloses formation, and it is simple in structure, easy and simple to handle, when use, jack is arranged in lifting hole(eyelet), and half chuck is enclosed in the lumps of wood and adds solid model surrounding, and the lumps of wood adds solid model one side for reserved bolt fuse; Upwards lift jack, make half chuck add solid model by clamping the tooth clamping lumps of wood; Upwards draw jack by hanging device, extract completely from prepared screw-bolt hole until the lumps of wood adds solid model, can greatly reduce labor strength, improve form removal efficiency, and safe and reliable.

2, clamp the L shaped body medial surface of tooth perpendicular to place, clamp tooth and can effectively prevent that the lumps of wood from adding solid model slippage, safe and reliable.

Brief description of the drawings

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

Fig. 2 is the structural representation of half chuck in Fig. 1;

Fig. 3 is use view of the present utility model.

Detailed description of the invention

Prepared screw-bolt hole as depicted in figs. 1 and 2 adds solid model form removal fixture, and it comprises the left clamp holder 1 and the right clamp holder 2 that are hinged by bearing pin 3, and the upper end of left clamp holder 1 and right clamp holder 2 offers lifting hole(eyelet) 4, and lifting hole(eyelet) 4 is for installing sling or rope.Be respectively equipped with half chuck 5 in the lower end of left clamp holder 1 and right clamp holder 2, half chuck 5 comprises the clamping tooth 52 on L shaped body 51 and L shaped body 51 medial surfaces, two halves chuck 5 can enclose to form with the lumps of wood and add square that solid model 7 adapts, and clamps L shaped body 51 medial surfaces of tooth 52 perpendicular to place.

Half chuck 5 is for being adjacent to the outer surface that adds solid model 7 at the lumps of wood, and left clamp holder 1 and right clamp holder 2, for adjusting the openings of sizes of half chuck 5, clamp tooth 52 and add solid model 7 for clamping the lumps of wood, to prevent that the lumps of wood from adding solid model 7 slippages.

In present embodiment, bearing pin 3 is the pin of Φ 22.

As shown in Figure 3, when the utility model uses, jack 6 is arranged in lifting hole(eyelet) 4, and half chuck 5 is enclosed in the lumps of wood and adds solid model 7 surroundings, and the lumps of wood adds solid model 7 one sides for reserved bolt fuse 8; Upwards lift jack 6, make half chuck 5 clamp the lumps of wood by clamping tooth 52 and add solid model 7; Upwards draw jack 6 by hanging device, extract completely from prepared screw-bolt hole until the lumps of wood adds solid model 7.
