Abstract

The utility model relates to a fixed bar, wherein the front end of the fixed bar forms a pointed cone, the rear end of the fixed bar forms a bayonet fixing apparatus. Using the bayonet fixing apparatus, the fixed bar is fixed in a fixing hole arranged on a sleeve barrel, which can be spurred by a power machine to drill holes on mould plates, or the fixed bar is fixed between two mould plates though the fixing apparatus breaks from the fixing hole. As using the fixed bar to drill holes, the fixed bar can be communicated with two mould plates once, and the utility model largely reduced the operate process.

Description

The structural improvement of template die fixed bar

Technical field

The utility model relates to the structural improvement of template die fixed bar, is intended to the boring of general template die and the program simplification of the secondary construction of fixed bar is set.

Background technology

Cause the demand property thereby the raising in house along with the increase of population; and the house of general reinforced concrete structure; all must be earlier when building fixedly behind the template die; be to charge with concrete in the middle of the template die; and template die is fixed; and during concrete placing; for increasing the intensity and the locating effect of template die; usually can between template die, be provided with fastening devices; and known engineering with the template die fastening devices as shown in Figure 1; its be in the two ends of a fixed bar 1 all car be provided with external screw thread 11; when construction; prior to being drilled with corresponding hole 21 on the two relative template dies 2,, and make its two end all protrude from the outside of two template dies 2 again with fixed bar 1 perforated holes 21; solid with nut 32 spiral shells again after being inserted in pad 31; utilizing fixed bar 1 that 2 of two template dies are fixedly gone out a required spacing, the bed knife of this fixed bar 1 because of be impulse power outside when charging concrete and pushing force in the same way, can reach preferable fixed effect really.

But, the time must be drilled with the program of hole 21 earlier in construction, just can wear fixed bar 1 then for the spiral shell fixed bit, twice construction sequence just can finish, if running into the construction point just must climb up when higher and climb down, comparatively bother in the construction simultaneously.

The utility model content

Main purpose of the present utility model is to solve above-mentioned disappearance, can and the program simplification of the secondary construction of fixed bar be set with general template die boring by fixed bar and sleeve.

For reaching above-mentioned purpose, fixed bar front end of the present utility model forms a pointed cone portion, the rear end then forms a holding division, but utilize this holding division holding to be fixed in the default embedding of the sleeve hole, its sleeve can be driven and start by power parts, be able to directly template die be holed, and simultaneously fixed bar is fixed between two template dies, and the holding division of fixed bar disengaging embedding hole gets final product, owing to can utilize fixed bar boring, fixed bar just can be arranged on two template dies in once constructing, can reduce the program of construction.

Description of drawings

Fig. 1 has fixed bar to be fixed in structural representation between two template dies for practising;

Fig. 2 is the structural perspective of fixed bar and sleeve in the utility model;

Fig. 3 to Fig. 5 is the structural representation of fixed bar construction action in the utility model.

[figure number explanation]

1 fixed bar, 31 pads

11 external screw threads, 32 nuts

12 pointed cone portions, 4 sleeves

13 holding divisions, 41 embedding holes

2 template dies, 411 internal threads

21 holes, 5 power parts

The specific embodiment

For the clear structure of the present utility model of your auditor is formed, and the overall operation mode, cooperate graphic being described as follows now:

The structural improvement of the utility model template die fixed bar, the structure of its fixed bar 1 as shown in Figure 2, its fixed bar 1 periphery is formed with external screw thread 11, its front end also forms a pointed cone portion 12, and the rear end then forms a holding division 13, but utilizes these holding division 13 holdings to be fixed in a sleeve 4 default embedding holes 41, in the present embodiment, in the present embodiment, embedding hole 41 form can with the fixed bar external screw thread 11 solid internal thread 411 of spiral shell mutually, fixed bar 1 is fixed on the sleeve 4.

During use, sleeve 4 is to be arranged on the power parts 5, after again desire bearing being aimed at by the pointed cone portion 12 of fixed bar 1, as shown in Figure 3, after activating 5 rotations of power parts, be that drive sleeve 4 is rotated thereupon, thereby drive fixed bar 1 rotation, because the rotation of fixed bar 1, the pointed cone portion 12 of its front end just can desire bearing and be drilled with out hole 21 on template die 2, and be drilled with out relative hole 21 back (as shown in Figure 4) at both sides template die 2, only need sleeve 4 is broken away from (as shown in Figure 5) by holding division 13 places of fixed bar 1, and the spiral shell that can carry out back pad 31 and screw 32 is again worked admittedly.

What deserves to be mentioned is, can directly utilize fixed bar boring, fixed bar just can be arranged on two template dies in construction once, can improve practise have must hole earlier with drill bit after, just can wear fixed bar between two template dies, must be with twice achievable shortcoming of construction sequence.

As mentioned above, the utility model provides a preferable feasible template die fixed rod structure improvement, so offer the application of novel patent in accordance with the law; Yet, above implementation and graphic shown in, be the utility model preferred embodiment, be not to limit to the utility model with this, be with, approximate with structure of the present utility model, device, feature etc., identical such as, all should belong to of the present utility model founding within purpose and the claim.
