Abstract
The utility model discloses a bolt pull rod sleeve for cast-in-place wall fixing template, which comprises a sleeve body. The sleeve body is a conical pipe with an axial inner hole. The bolt pull rod sleeve for the cast-in-place wall fixing template has the advantages of being simple in structure, convenient to disassemble, capable of being reused, saving, environment-friendly and the like.
Description
Technical field
The utility model relates to the cast-in-place wall fixed form that a kind of building operations uses and uses the bolt draw bar sleeve.
Background technology
Present cast-in-place wall form mostly adopts bolt draw bar to fix, and for the convenient bolt draw bar that takes out after concrete setting, just folder is established many sleeves between two templates, is installed in bolt draw bar in the sleeve.But sleeve can be bonded in the body of wall after the concrete setting, and on body of wall, forms many holes, if not with on the hole repairing, and the consequence that causes body of wall to leak in then can use afterwards.The bamboo pole that the sleeve of present domestic use generally adopts inside to empty, and bamboo pole is similar to cylinder owing to profile, and out-of-shape, bamboo pole is difficult to from body of wall, take out after the concrete setting, generally need ask the professional person to get bamboo pole, has increased cost.And owing to take out difficulty, bamboo pole can damage or fracture in the taking-up process, can not reuse; Void shape after the bamboo pole out-of-shape causes and takes out in addition is also irregular, may have the slit because of filling-up hole is imperfect, causes body of wall to leak.
The utility model content
The technical problem that the utility model will solve is: to the problem that prior art exists, the cast-in-place wall fixed form that a kind of simple in structure, convenient disassembly is provided, can reuse is used the bolt draw bar sleeve.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of cast-in-place wall fixed form is used the bolt draw bar sleeve, comprises sleeve body, and said sleeve body is for axially having the conical pipe of endoporus.
Further improvement as the utility model:
Said endoporus is a bellmouth.
Compared with prior art, the advantage of the utility model is:
1, the tube-in-tube structure of the utility model is simple, owing to adopt the conical pipe structure, only needs during dismounting to knock gently in the smaller diameter end of sleeve with hammer or other instruments, just can sleeve easily be taken out, and is convenient and strength-saving; And the sleeve that takes out is reusable, and economical environment-protective greatly reduces dress mould cost; Moreover the sleeve-shaped rule, the void shape after taking out is rule also, and work brings convenience to filling-up hole, guarantees that filling-up hole is complete, avoids body of wall to leak.
2, the endoporus of the sleeve of the utility model is made pyramidal structure, can save material, further reduces the cost of manufacture of sleeve.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is applied to the structural representation on the cast-in-place wall form for the utility model.
Marginal data: 1, sleeve body; 2, endoporus; 3, template; 4, bolt draw bar; 5, nut; 6, grapple.
The specific embodiment
Below will combine accompanying drawing and specific embodiment that the utility model is done further explain.
As shown in Figure 1, the cast-in-place wall fixed form of the utility model is used the bolt draw bar sleeve, comprises sleeve body 1, and sleeve body 1 is for axially having the conical pipe of endoporus 2.The material that bush material can adopt PVC or other low prices and have certain intensity, even sleeve in use damages, also recyclable its material further reduces the cost of manufacture of sleeve.The length of sleeve can be formulated according to the thickness of body of wall to be poured.As shown in Figure 2, during use, between the template 3 of two positioned opposite, with support shuttering 3, the position of corresponding sleeve has through hole on the template 3 with collet head; From through hole and sleeve, pass bolt draw bar 4 then, locking nut 5 is tightly grabbed on two templates 3 grapple 6 on the bolt draw bar 4, thereby fixing two templates 3.Just can be after template 3 is put up toward fluid concrete in the cavity between the template 3; After treating concrete setting, body of wall moulding; Take off bolt draw bar 4 and template 3 more successively; Knock gently in the smaller diameter end of sleeve with hammer or other instruments at last, sleeve is withdrawed from from the other end, unloading process is convenient and strength-saving; And the sleeve that takes out is reusable, and economical environment-protective greatly reduces dress mould cost; Moreover the sleeve-shaped rule, the void shape after taking out is rule also, and work brings convenience to filling-up hole, guarantees that filling-up hole is complete, avoids body of wall to leak.
In the present embodiment, the endoporus 2 of sleeve is a bellmouth, under the prerequisite that guarantees sleeve intensity, reduces wall thickness as far as possible, to save material, further reduces the cost of manufacture of sleeve.The wall thickness of the end that sleeve outer diameter is little should be bigger than external diameter the wall thickness of an end big slightly, with sleeve for convenience detach.
Below only be the preferred implementation of the utility model, the protection domain of the utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to the protection domain of the utility model.Should be pointed out that for those skilled in the art,, should be regarded as the protection domain of the utility model in the some improvement and the retouching that do not break away under the utility model principle prerequisite.
