Abstract
The utility model discloses a horizontal internal formwork supporting device which comprises a PVC (polyvinyl chloride) pipe sleeve and reinforcing steel. The reinforcing steel is disposed on the axial center line of the PVC pipe sleeve, and fine aggregate concrete is filled between the reinforcing steel and the PVC pipe sleeve. The PVC pipe sleeve, the reinforcing steel and the fine aggregate concrete are structurally integrated, two shortcomings including insufficient stability of the reinforcing steel and high brittleness of the concrete are overcome, small cost input has an active promotion effect on truly improving construction quality, and the size of a section is effectively controlled in a pouring process.
Description
Technical field
The utility model relates to beam, post, the horizontal inner supporting device of wall form.
Background technology
Form work engineering in the Structural Engineering subitem construction, when adopting split bolt control concrete pouring to the pressure of side form; Adopt the thickness of cushion block control topping; Adopt support and control sectional dimension in the template level.The planeness of support shuttering and stressed even before under these three kinds of different devices are auxiliary, just guaranteeing concreting.
In investigation, find, in the existing form work engineering, support lengths of rebar or the plain concrete control sectional dimension of the 8～10mm of employing in the level more.But the problem of the two existence is: the reinforcing bar slenderness ratio is excessive, and stability is not enough, is prone in the split bolt rundown process bend, and just do not play the effect in control cross section, and reinforcing bar easy-to-rust in air influences the steel concrete durability; Plain concrete fragility is big, under the condition that does not stress, just is prone to rupture, and this is ineffective often for horizontal support.Therefore to the improvement of supporting in the template level be and be necessary.
The utility model content
The utility model technical problem to be solved just provides the horizontal inner supporting device of a kind of template, in order to effectively the size in the cross section in the process of building is played the effect of control, overcomes the not enough and big problem of concrete fragility of reinforcing bar stability.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: the horizontal inner supporting device of a kind of template; It is characterized in that: comprise a pvc pipe cover and a reinforcing bar, reinforcing bar is located at pvc pipe and is overlapped on the axial center line, and reinforcing bar and pvc pipe inner room are filled pea gravel concreten.
As preferably, the horizontal inner supporting device of said template is a square, and sectional dimension is 20mm * 20mm or 22mm * 22mm.
As preferably, said reinforcing bar adopts the reinforcing bar of φ 8mm～φ 10mm.
As preferably, said pvc pipe sleeve wall thickness is 1mm.
The utility model device is made of one structure with pvc pipe cover, reinforcing bar and pea gravel concreten; Not enough and two the big problems of concrete fragility of reinforcing bar stability have been overcome; Positive impetus has been played in the solid improvement to construction quality of a little input of cost, effectively the size in the cross section in the process of building is played the effect of control.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described:
Fig. 1 is the application sketch map of the utility model;
Fig. 2 is the utility model cross sectional representation;
Fig. 3 is an I-I generalized section among Fig. 2;
The specific embodiment
To shown in Figure 3, be the embodiment of the horizontal inner supporting device of a kind of template of the utility model like Fig. 1, comprise 1 and reinforcing bar 3 of a pvc pipe cover, reinforcing bar is located at pvc pipe and is overlapped on the axial center line, and reinforcing bar and pvc pipe inner room are filled pea gravel concreten 2.The horizontal inner supporting device 7 of template is a square, and sectional dimension is 20mm * 20mm or 22mm * 22mm.Said reinforcing bar adopts the reinforcing bar of φ 8mm～φ 10mm.Said pvc pipe sleeve wall thickness is 1mm.
In the form work engineering work progress, to the pressure of side form 5, the horizontal inner supporting device of template is similar to the steel concrete of outsourcing square steel pipe, square sectional during 4 cast of split bolt 6 control concrete.Be respectively the 1mmPVC pipe from outside to inside, play the effect of stirrup; Pea gravel concreten plays the effect of resistance to compression and topping; φ 8～10mm reinforcing bar plays the vertical stressed effect of muscle, tries one's best symmetrically and evenly in the position of layout, and transposition is near Screw arbor with nut at both-ends 6.
