Abstract
A hollow plastic corner sectional material for a construction formwork system is characterized in that a plastic body with a right-angle cross section is included, and heat dissipation lightening holes are formed in the body. The sectional material mainly replaces a construction square timber, and therefore the problems of connection through the square timber in the constructing process of a construction formwork are fundamentally solved. For example, the sectional material can completely replace the square timber to seal a lap joint opening at a lap joint of wall corner formworks, construction common problems of mortar extrusion, mortar leakage, formwork displacement, non-flatness of structural lines and the like can be effectively avoided, the formwork is easy to disassemble, and the flat and square concrete surface effect of a corner is more attractive. When the hollow plastic corner sectional material is applied to a beam bottom formwork, the sectional material only needs to be located, and then forming is achieved as long as the formwork and a support are placed according to the size.
Description
Technical field
The utility model relates to a kind of template for construction form erecting system, relates in particular to and adopts architectural shape that hollow plastic the makes structure as template.
Background technology
In building engineering construction, concreting needs a large amount of lumps of wood.In the corner of wall, after both sides wooden form overlap joint, by the lumps of wood and wooden peg location, its shortcoming had three: one in the past, and the lateral pressure produced during pouring concrete can cause the wooden form displacement, and the situation of spillage, running pulp easily appears in seam crossing; The 2nd, wooden form easily is absorbed in concrete, causes form removal inconvenience, needs to use the powerful form removals of instrument such as crowbar, and damaged template is serious; The 3rd, due to the existence of spillage, running pulp phenomenon, affected the attractive in appearance of concrete component corner.In addition, when the formwork of beam bottom, need first template and the lumps of wood to be nailed together to the composition beam bottom board, then, by the beam bottom board location, efficiency of construction was low and waste of material is serious in the past.The lumps of wood is wasted resource, reclaims difficulty, and, also there are many deficiencies in the plastic formwork that building trade occurs recently, and some hardness is high, poor toughness, easy embrittlement, and bad processing, some rigidity is inadequate, yielding.
The utility model content
Technical problem to be solved by this invention is to overcome the deficiency of above-mentioned prior art, a kind of easy to use, the corner section bar of the hollow plastic for construction form erecting system that is difficult for spillage that provide.
According to a kind of corner section bar of the hollow plastic for construction form erecting system provided by the invention, comprise that a cross section is the right angle plastic body, is formed with the heat dissipation weight-reducing hole on described body.
Also there is following attached technical characterictic according to a kind of corner section bar of the hollow plastic for construction form erecting system provided by the invention:
Described body is foaming single or multiple lift structure.
Described body is extruded and is processed continuously by extruder integral body.
The bearing of trend in described heat dissipation weight-reducing hole is vertical with the cross section of described body, and runs through described body.
Described body is strip structure or block structure.
The 10%-30% of the cross section gross area that the section area in described heat dissipation weight-reducing hole is described body.
The cross-sectional height of described body and width are 80mm-160mm, and thickness is 40mm-80mm.
Be provided with three described heat dissipation weight-reducing holes on described body, lay respectively at the junction of two right-angle sides and two right-angle sides, the described heat dissipation weight-reducing hole that wherein is positioned at right-angle side is square opening, and the described heat dissipation weight-reducing hole that is positioned at junction is circular port.
A kind of corner section bar of the hollow plastic for construction form erecting system provided according to the utility model compared with prior art has following advantage:
1, section bar of the present utility model is mainly used in substituting the building lumps of wood, when solving construction formwork construction in the past at the bottom of side, uses the lumps of wood to connect problem and the defect occurred.For example, in wall corner formwork lap-joint, can replace the lumps of wood will overlap a mouthful sealing fully, can effectively prevent the appearance of the construction common faults such as running pulp, spillage, template are shifted, the works lines are not straight, be easy to the dismounting of template simultaneously, upright concrete face effect that corner is straight is more attractive in appearance; For at the bottom of beam during formwork, only need first this section bar location, then put template and support plastic according to size.
When 2, this section bar is for beam, post construction, without hammering into steel nail, connect, greatly improved the efficiency of construction of installation, dismounting, saved the use amount of small-sized consumptive material as auxiliary material such as steel nail, steel wires simultaneously, reduced construction cost, the industrial accident of also having avoided job site to cause because of unrestrained steel nail, steel wire everywhere.
3, this section bar is the entity plate, and middle perforate has effectively reduced the raw material consumption on the one hand, has reduced the section bar deadweight, is convenient to workman's carrying and installation at the construction field (site); In the section bar manufacturing process, calorific value is large on the other hand, and reserving hole easily dispels the heat, guaranteed the integrality of section bar, and the deformation of having avoided product to occur has aborning met in construction the requirement to the formwork keel glacing flatness.
4, foaming monolayer plastic architectural shape of the present utility model has been determined scientific matching, make after moulding that the section bar top layer is smooth, wear-resisting, fire-retardant, good toughness, lightweight, good rigidly, easily sawed, the construction processing such as boring, strong and unyielding combination, improved the combination property of section bar.
5, this Surface of profile is smooth smooth, easy to clean, and long service life, substitute the wooden lumps of wood with plastic material, is conducive to reusing and the reclaiming utilization of section bar, is conducive to reduce construction cost, saved valuable timber resources simultaneously, protected ecological environment.
