Description
Technical field
The utility model relates to the realm of building construction, more particularly to one kind based on strip leakage-proof structure between prefabricated board.
Background technique
Prefabricated board strip is strip crevice reserved before pouring en-block construction floor, is the structure for connecting two sides prefabricated board
It makes, generallys use template block in strip bottom, then casting concrete to form an entirety at strip.This construction
Key point be how to make the tight block of template in strip bottom, it is beautiful to pour rear structure for not spillage when guarantee pours.
Traditional hoisting die construction way is that prefabricated board is preset to tongue and groove (i.e. right-angle notch), then by the template of fit size
Insert plate band bottom, and so that template two sides is extended to tongue and groove, then template is shored fixation using bottom support column.Although this way
It is fairly simple, but have disadvantages that mainly there are following three disadvantages:
First is that being not easy to coincide at template and the EDGE CONTACT of prefabricated board, it is easy to appear gap, is held very much in vibrated concrete
Easily from gap spillage；
Second is that lateral pressure and concrete itself when the template at strip will receive the pressure of prefabricated board, vibrated concrete
The effect of the multiple pressures such as gravity, so that the support requirement to the template at strip is more harsh, if the support of template lower part is inadequate,
Easily cause the deformation of template and generate gap, mortar is caused to leak out；
Third is that since template is embedded in strip bottom, so after demoulding, it is also necessary to it is manually levelling to strip bottom, no
But it is beautiful to influence structure, and post-processing will also result in the waste of personnel, increases cost.
Summary of the invention
To solve the above problems, the utility model provides a kind of strip leakage-proof structure between being based on prefabricated board, to conventional method
It is improved, prefabricated board is changed to inclined-plane notch from original tongue and groove in advance, without reducing template for template insert plate band
With the contact at prefabricated board edge, keep template tighter to the block of strip, and reduces the artificial treatment in later period；In addition will
The mode by support column support shuttering originally is modified to the mode by split bolt formboard fastening and prefabricated board, makes the branch of template
Support is more firm.
The utility model is realized especially by following technical proposals: one kind is based on strip leakage-proof structure between prefabricated board, packet
It includes: being in the strip of strip crevice between prefabricated board, block is in the template of the strip lower openings, wherein
The prefabricated board predetermined slope notch, and the inclined-plane notch is connected to the strip, expands as the strip
Up-narrow and down-wide structure.
Size requirement using above-mentioned inclined-plane gap structure, it is not necessary that the template is embedded in the strip, to the template
It is more flexible, and the template only needs to be adjacent to the prefabricated board in vertical direction, reduce connecing for template and prefabricated board edge
Touching, keeps the template tighter to the block of the strip；In addition, strip is expanded as up-narrow and down-wide structure by inclined-plane notch,
The area for contacting template with concrete expands, and has dispersed the pressure of template receiving, keeps the support of template more firm, effectively anti-
Only concrete leaks outside and influences the beauty of structure, while reducing the waste of personnel and cost caused by post-processing.
The utility model it is a kind of based between prefabricated board strip leakage-proof structure further improvement lies in that, the inclined-plane notch is pre-
It is connected to set on the lower part of the prefabricated board, and with the strip lower part.
Inclined-plane notch only is opened up to the lower part of the prefabricated board, on the basis of not changing original effect, is reduced described oblique
The volume of face notch improves the load-bearing capacity of the prefabricated board.
The utility model it is a kind of based between prefabricated board strip leakage-proof structure further improvement lies in that, the inclined-plane notch
Inclined-plane and prefabricated board bottom surface angle are in 45 degree.
By the restriction of above structure, make the leakage-proof structure that the premise of spillage situation occur when reducing concreting
Under, while the load-bearing capacity of the prefabricated board is not influenced.
The utility model it is a kind of based between prefabricated board strip leakage-proof structure further improvement lies in that, comprising:
Cross bar, the cross bar are located at the upper opening of the strip；
The cross bar is fixed in split bolt, described split bolt one end, and the other end of the split bolt passes through described
Template is simultaneously fixed by nuts.
Using the above structure instead of traditional upright supports, keep the template tighter to the block of the strip, and
Reduce the cost of labor for setting up column.
The utility model it is a kind of based between prefabricated board strip leakage-proof structure further improvement lies in that, the prefabricated board and institute
It states the position pressure between template and close to the strip two sides and is equipped with sponge strip.
By adding sponge strip, the template is further increased to the tightness of the strip block, it is significantly more efficient anti-
The occurrence of leak-stopping is starched.
To sum up, the utility model include but is not limited to it is following the utility model has the advantages that
1, of simple structure and low cost, easy for construction；
2, shuttering supporting consolidate, be unlikely to deform, structure it is beautiful；
3, it effectively prevent spillage, improve construction quality.
