The utility model discloses a reinforcing device for a columned template, which comprises a steel bar, a threaded sleeve, a screw rod, and a nut matched with the screw rod for use, wherein the threaded sleeve is fixedly mounted at one end of the steel bar; and the screw rod is fixedly mounted at the other end of the steel bar. During the use, the screw rod penetrates through the threaded sleeve, and the nut lock the section, extending out of the screw rod, of the threaded sleeve onto the threaded sleeve. According to the utility model, materials can be drawn easily, the operation is easy, the practical operability of workers is high, the frequency of construction turnover is high, the maintenance is flexile, and the cost is low; after the columned template is reinforced by the reinforcing device, the strength, rigidity and stability of the reinforcing system can be excellently controlled, the concrete column can be formed through one-time concreting, the situations such as template expanding, template shifting, template cracking can be avoided, and the appearance and quality are excellent after the template of the column is removed.
Description
Technical field
The utility model relates to the realm of building construction, particularly a kind of bracing means for column-form.
Background technology
Reinforced Concrete Circular Cylinder belongs to a kind of structure that building field generally adopts, and in construction works, concrete need be poured into a mould in the column-form, thereby be formed required Reinforced Concrete Circular Cylinder.Existing column-form mainly uses flitch to reinforce, and still, the mould that expands appears in this reinforcing mode intensity limited and less stable easily.
The utility model content
Technical problem to be solved in the utility model provide a kind ofly be convenient to draw materials, the bracing means that is used for column-form of with low cost, easy construction, easy operating.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of bracing means for column-form comprises reinforcing bar, screw shell, screw rod and the nut that is used with described screw rod, and an end of described reinforcing bar is fixed with described screw shell, and the other end of this reinforcing bar is fixed with described screw rod; During use, described screw rod passes described screw shell, and described nut is locked at the part that this screw rod stretches out described screw shell on this screw shell.
Preferably, described screw shell and screw rod are welded on the described reinforcing bar.Adopt solder technology, easy and simple to handle and bonding strength is higher.
Preferably, described reinforcing bar is screw-thread steel.Screw-thread steel can guarantee the intensity of reinforcing to have taken full advantage of the moulding of reinforcing bar again, can make reinforcing more solid and reliable well around cylinder.
Preferably, described screw rod is high-strength screw rod.High-strength screw rod can increase the number of times that turnover utilizes greatly, thereby saves cost.
The utility model is used for the bracing means of column-form, draw materials easily, easy operating, workman's actual operation are strong, construction number of turnover height, maintenance flexibly, with low cost.Adopt the column-form after this bracing means is reinforced, the intensity of reinforcement system, rigidity, stability have obtained better controlled, the concrete cylindrical one-time cast-forming, and the situations such as mould, race mould, sudden and violent mould that occur expanding, after the pillar form removal, presentation quality is good.
Description of drawings
The structural representation of the bracing means that is used for column-form that Fig. 1 provides for the utility model;
Screw rod and screw shell connection diagram when the bracing means that is used for column-form that Fig. 2 provides for the utility model uses;
The bracing means that is used for column-form that Fig. 3 provides for the utility model uses view when constructing.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
From Fig. 1 to the utility model embodiment shown in Figure 3 as can be known:
As depicted in figs. 1 and 2, the utility model is used for the bracing means of column-form, comprises reinforcing bar 1, screw shell 2, screw rod 3 and the nut 4 that is used with screw rod 3, and an end of reinforcing bar 1 is fixed with screw shell 2, and the other end of this reinforcing bar 1 is fixed with screw rod 3; During use, described screw rod 3 passes described screw shell 2, and the part that described nut 4 stretches out described screw shell 2 with this screw rod 3 is locked on this screw shell 2.
Preferably, screw shell 2 and screw rod 3 are welded on the reinforcing bar 1.Adopt solder technology, easy and simple to handle and bonding strength is higher.Screw shell 2 and screw rod 3 all adopt double welding with the welding of reinforcing bar 1, and fusion length satisfies 〉=5d (d is reinforcing bar 1 diameter).
Reinforcing bar 1 preferred screw-thread steel, particularly minor diameter screw-thread steel can guarantee the intensity of reinforcing to have taken full advantage of the moulding of reinforcing bar again, can make reinforcing more solid and reliable well around cylinder.
The diameter of reinforcing bar is according to pillar diameter, height and topple over the load that concrete produces, and is definite by calculating, and simultaneously according to field experience, can select according to following:
Post height≤3 meter, the reinforced steel diameter adopts three grade 8;
Post height＞3 meter, the reinforced steel diameter adopts three grade 10.
Reinforcing bar 1 cutting length design formulas is: L=π * (D+2*t+2*h)
Wherein: the diameter of D-cylinder; The thickness of t-column-form; The height of h-reinforcing flitch.
When actual blanking, cutting length to guarantee producing certain amount of tightening when tightening reinforcing with nut 4, makes the tighter of formwork reinforcement than the little 20-30mm of calculated length, more can guarantee the intensity of reinforcing.(this is the key of whole hardened system, adds will pay special attention to man-hour)
Screw rod 3 preferred high-strength screw rods.Can increase the number of times that turnover utilizes greatly, thereby save cost.Common Screw arbor with nut at both-ends is using under 3-4 time the situation, and screw thread will be erased, and can not continue utilization.Nut 4 can adopt round nut or castle nut etc. as long as diameter and high-strength screw rod are supporting when project construction.
Use of the present utility model (construction) method is as follows:
One, according to pillar and template parameter processing and fabricating bracing means;
Two, the job site cylinder is installed column-form 5;
Three, flitch 6 is reinforced in column-form 5 outer fixed installations;
Four, bracing means is installed around post;
Five, fastening nut 4;
Six, template and reinforcement system are inspected for acceptance;
Seven, concreting.
Construction back state as shown in Figure 3.
The utility model is used for the bracing means of column-form, draw materials easily, easy operating, workman's actual operation are strong, construction number of turnover height, maintenance flexibly, with low cost.Adopt the column-form after this bracing means is reinforced, the intensity of reinforcement system, rigidity, stability have obtained better controlled, the concrete cylindrical one-time cast-forming, and the situations such as mould, race mould, sudden and violent mould that occur expanding, after the pillar form removal, presentation quality is good.
In sum, content of the present utility model is not limited in the above-described embodiments, and those skilled in the art can propose other embodiment easily according to guiding theory of the present utility model, and these embodiments all are included within the scope of the present utility model.
