Abstract
The utility model relates to a device for reserving bolt hole, including a plank sheathing system bolt box, it wraps up the one deck protection film at this plank sheathing system bolt box outer wall, the utility model discloses it is convenient more traditional simple wood system template bolt box ann to tear open, and work efficiency is high, low in labor strength, and the construction progress is fast. The embedded bolt box is simple to manufacture, can be repeatedly used, is easy to disassemble and remove, avoids pollution and ensures quality. Reducing chiseling, being beautiful and practical, being green in construction and saving labor cost. Can be repeatedly used, reduces repeated processing and manufacturing, saves materials and reduces cost.
Description
Technical field
The utility model belongs to industrial construction field, especially a kind of device for prepared screw-bolt hole.
Background technology
Current industrial construction industry equipment Foundations are pre-buried a large amount of bolt all, but for assurance equipment is installed the requirement to bolt installation accuracy, a lot of designs adopt prepared screw-bolt hole, it is to use composite board to make bolt box that traditional prepared screw-bolt hole stays equipment, method, corrugated bushing bolt preformed hole or tailor-made foam block bolt preformed hole etc., in construction, in dismounting and scale removal process, in various degree expose series of problems: 1, the simple cost of wooden form bolt box processed own is lower, but make and remove, need in a large number manually, especially when prepared screw-bolt hole is all darker, can only be with crooked chisel destructive dismounting by force after concrete construction completes, make the concrete local failure of prepared screw-bolt hole top simultaneously, muscle phenomenon is revealed in causing of having, the simple not reproducible utilization of wooden form bolt box processed, and inconvenient dabbing and cleaning in hole in addition, affects secondary and buries bolt and the concrete really power of holding after bolt underground, being affected to uplift force of bolt.2, after the construction of corrugated bushing bolt box, can not take out, cost is higher, increases cost.3, customized foam bolt preformed hole, the process-cycle is long, and cost is high, and dabbing is inconvenient, and in scale removal process, broken foam can not be well controlled, and causes environment pollution.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of device for prepared screw-bolt hole is provided, this apparatus cost is low, peace is torn open conveniently, can reuse, needn't dabbing, cleaning is convenient.
The utility model solves its technical problem and is achieved through the following technical solutions:
For a device for prepared screw-bolt hole, comprise wooden form bolt box processed, it is at this wooden form bolt box outer wall parcel processed layer protecting film.
And described diaphragm tightly wraps on wooden form bolt box outer wall processed by adhesive tape.
And described diaphragm is PE film, PE film thickness is 4.5mm.
And described diaphragm is waterproof film.
And described diaphragm is multilayer complex films.
Advantage of the present utility model and beneficial effect are:
This,, for the device of prepared screw-bolt hole, comprises wooden form bolt box processed, and it is at this wooden form bolt box outer wall parcel processed layer protecting film, and this is simple in structure, cost is low, peace is torn open conveniently, can reuse, needn't dabbing, clear up conveniently.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
For a device for prepared screw-bolt hole, comprise wooden form bolt box 2 processed, it is at this wooden form bolt box outer wall parcel processed layer protecting film 1, and diaphragm can tightly wrap on wooden form bolt box outer wall processed by adhesive tape.Diaphragm can be PE film, and PE film thickness is 4.5mm, and diaphragm can be waterproof film, and diaphragm can be multilayer complex films.
The utility model tightly swathes PE film with adhesive tape on the basis of simple wooden form bolt box processed, uncovered back cover while passing, after installation, clip fixing, after concrete initial set, before final set, extract wooden model bolt box and remove again PE film, by the design bolt preformed hole size customized bolt box of wooden form, with the thick PE film of 4.5mm, wrap up one deck, with adhesive tape, tightly wrap, from bed course life, set bolt box reinforcing bar is taken root fixingly to being wrapped with the bolt box of PE film, with flitch, steel pipe, bolt box is beared down on one fixing.According to the fixing bolt box of appeal method, when removing, only need to remove after bearing down on one and prize a little wooden form bolt box, rock from side to side, just can intactly bolt box be extracted, finally PE film is removed, the tub after use divides model to stack, and convenient have same size bolt box to reuse again.Because PE film is subject to concrete extruding, certain convex-concave can be produced, after bolt hole cleaning, needn't dabbing just good frictional interface can be formed.The more traditional simple wooden form bolt box peace of the utility model is torn open conveniently, and operating efficiency is high, and labour intensity is low, and construction speed is fast.Pre-embedded bolt box is made simple, can reuse, and readily removable removing, avoids polluting, and ensures the quality of products.Reduce dabbing, both artistic and practical, green construction, saves labour cost.Can reuse, reduce and repeat processing and fabricating, save material, reduction expense.
