Abstract

The utility model discloses a sleeve fixator which is used for fixing a sleeve on a bottom pattern plate. The sleeve fixator comprises a cross-shaped pressing buckle, a hook bolt and a nut. The cross-shaped pressing buckle is composed of four L-shaped pressing plates, the L-shaped pressing plates comprise short sides and long sides, the short sides are bent to form a right angle with the long sides, strip-shaped through holes are arranged in the middle of the long sides, the long sides of two L-shaped pressing plates are oppositely overlapped to form a Pi-shaped pressing buckle, and two Pi--shaped pressing buckles are mutually staggered to form the cross-shaped pressing buckle. The lower end of the hook bolt is provided with a hook formed by a bent right angle, and the upper end of the hook bolt is provided with threads. The cross-shaped pressing buckle is arranged at the upper edge mouth of the sleeve, and short sides of the cross-shaped pressing buckle are buckled at the upper mouth edge of the sleeve. The upper end of the hook bolt passes through an opening hole of the bottom pattern plate, the hook is connected with the bottom pattern plate, and the upper end of the hook bolt passes through the strip-shaped through hole from the sleeve to be connected with the nut. The sleeve fixator has a simple structure, is convenient and fast to assemble and disassemble and can be reused.

Description

Anchor

[technical field]

The utility model relates to the building operations instrument, relates in particular to a kind of anchor, is used for fixing pre-buried sleeve pipe in Cast-in-place concrete floor slab construction process.

[background technology]

In building operations, service sleeve and preformed hole are important and frequent working procedures.Particularly in Cast-in-place concrete floor slab construction process, in order to satisfy the needs that water, electricity, vapour, air-conditioning duct etc. are installed, prior corresponding sleeve pipe of set aside pre-embedded of palpus or preformed hole during civil engineering.

Traditional set aside pre-embedded method is as follows:

1) before the concrete construction, service sleeve adopts direct pre-buried method, and reinforcing bar such as outside of sleeve and floor etc. nearby carry out respective fixation;

2) adopt the method for back perforate to set up sleeve pipe (or preformed hole) after the concrete structure construction finishes.

The weak point of traditional set aside pre-embedded method is:

1) outside of sleeve and floor etc. nearby reinforcing bar to fix its method improper, concrete is built in the process because the influence of lateral pressure can cause sleeve pipe to produce lateral displacement, can not guarantee the accurate position of set aside pre-embedded;

2) carrying out secondary perforate meeting after structure is finished again influences the concrete architecture quality, particularly when perforate is big, presses code requirement, can't increase reinforcing rib around the hole, causes local cracking easily.

[summary of the invention]

The technical problems to be solved in the utility model provides a kind of simple in structure, installs and removes anchor easily.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is that a kind of anchor is used for sleeve pipe is fixed on soffit formwork, comprises cross clinching, HOOK BOLTS and nut; Described cross clinching is made of four L shaped pressing plates, L shaped pressing plate comprises minor face and long limit, and the minor face bending meets at right angles with long limit, and the centre on long limit has the bar shaped groove, the long limit of two L shaped pressing plates is built up a font clinching in opposite directions, the clinching of the interlaced formation cross of two door fonts clinching; The HOOK BOLTS lower end is the eave tile of right angle bending, and there is screw thread the upper end, and the bar shaped groove that the cross pressing plate is passed in the upper end of HOOK BOLTS is connected with nut.

Above-mentioned nut edge joint weld spreading bar round steel.

The length of above-mentioned HOOK BOLTS and the height of sleeve pipe are suitable.

The beneficial effects of the utility model are that simple in structure, it is convenient to install and remove, and can reuse.

[description of drawings]

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the utility model anchor embodiment front view (installment state).

Fig. 2 is the utility model anchor embodiment vertical view (installment state).

Among the figure, 1-sleeve pipe, 2-HOOK BOLTS, 3-nut, the rectangular round steel of 4-, 5-L shape pressing plate, 6-L shape pressing plate, 7-L shape pressing plate, 8-L shape pressing plate, 9-soffit formwork.

[specific embodiment]

In Fig. 1, a kind of anchor is used in advance sleeve pipe 1 being fixed on soffit formwork 9 before the cast-in-situ floor construction, comprises cross clinching, HOOK BOLTS 2 and nut 3.

In Fig. 2, the cross clinching is made of four L shaped pressing plates, L shaped pressing plate comprises minor face and long limit, the minor face bending meets at right angles with long limit, the centre on long limit has the bar shaped groove, the long limit of L shaped pressing plate 5 and 6 is built up a font clinching in opposite directions, and the long limit with L shaped pressing plate 7 and 8 is built up the clinching of another one door font in opposite directions equally, again with the clinching of the interlaced formation cross of two door fonts clinching.

HOOK BOLTS 2 lower ends are the eave tile of right angle bending, and there is screw thread the upper end.

During installation, the cross clinching is contained in the upper edge hole place of sleeve pipe 1, the minor face of cross clinching is buckled in sleeve pipe 1 upper brim edge.The height that the length of HOOK BOLTS 2 will compare sleeve pipe 1 omits long.A strip hole is dug in the sleeve pipe center on soffit formwork, the lower end of HOOK BOLTS 2 tapping from soffit formwork is passed, eave tile is revolved again and turn 90 degrees the back and be connected with soffit formwork 9, the bar shaped groove that the upper end of HOOK BOLTS 2 is passed the cross pressing plate in the sleeve pipe 1 is connected with nut 3.

For convenient quick fastening nut 3, at nut edge joint weld spreading bar round steel 4, rectangular round steel serves as handle to be used.

Claims

1. an anchor is used for sleeve pipe is fixed on soffit formwork, it is characterized in that, comprises cross clinching, HOOK BOLTS and nut; Described cross clinching is made of four L shaped pressing plates, described L shaped pressing plate comprises minor face and long limit, the minor face bending meets at right angles with long limit, the centre on long limit has strip through-hole, the long limit of two L shaped pressing plates is built up a font clinching in opposite directions, the clinching of the interlaced formation cross of two door fonts clinching; Described HOOK BOLTS lower end is the eave tile of right angle bending, and there is screw thread the upper end, and the strip through-hole that the cross pressing plate is passed in the upper end of HOOK BOLTS is connected with nut.
