Abstract
The utility model discloses a protection device of protective layer thickness of concrete simple beam, including setting up the support at the steel reinforcement cage tetrapod, the inboard of support sets up atress reinforcing bar recess, and atress reinforcing bar recess comprises vertical face, indent arcwall face and horizontal plane, the indent radius of indent arcwall face suits with the radius of vertical atress reinforcing bar of steel reinforcement cage, along vertical face, indent arcwall face and horizontal plane transversely set up the stirrup recess, the radius of stirrup recess suits with the radius of the stirrup of steel reinforcement cage. The thickness on inside reinforcing bar position of the fixed simple beam of the simple and convenient effectual accuracy of this protection device ability and control protection layer to the experimental result error that the simple beam reinforcing bar shifted and the protective layer inaccuracy arouses has been reduced.
Description
Technical field
The utility model relates to a kind of reinforced concrete simple-supported beam education experiment, particularly relates to a kind of protective device of protective layer thickness of concrete simply supported beam.
Background technology
Reinforced concrete beam is that component is commonly used in building structure, and when carrying out the design of beam, designer has larger flexibility when determining the sectional dimension of beam usually, and different sectional dimensions determines different quantity of reinforcement.Thus the thickness of its topping also there will be difference; certainly also because reinforced concrete simple-supported beam is for teaching and the representative meaning of application at ordinary times; in beam, the stress performance of control to beam that be fixing and topping of reinforcing bar is of crucial importance; and very huge on the impact of the result data of corresponding experiment, also serious on the impact of corresponding engineering.Concrete cover was controlled in the past and the reinforcing bar method of fixing mainly with the split heads form of mortar, steel, plastic cushion; just to determining bottom surface protective layer thickness; but space orientation and the lateral protection layer thickness of reinforcing bar cannot be determined; also the simply supported beam be not suitable in teaching test makes, and can cause certain error to experimental result.Traditional reinforcing bar fixing means is inapplicable in experiment or education experiment, adopts colligation cushion block, adds fixing accurate not to reinforcing bar of the modes such as plastic clip; And when carrying out reinforced concrete simple-supported beam experiment, because the thickness of topping does not reach perfect condition, the experimental data often obtained and finite element analysis software obtain result and differ huge.Therefore, need to adopt a kind of simple and fast and fix reinforcing bar in simply supported beam accurately, thus also ensureing the new equipment of reinforcing bar location and thickness of concrete cover.
Utility model content
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of protective device of protective layer thickness of concrete simply supported beam.Can reinforcing bar and control thickness of concrete cover in clamped beam accurately by the protective device of the protective layer thickness of this concrete simply supported beam, and impart knowledge to students in the concrete simply supported beam component used for civil engineering test.
In order to solve the problems of the technologies described above, the utility model have employed following technical scheme:
A protective device for the protective layer thickness of concrete simply supported beam, comprises the bearing being arranged on reinforcing cage tetrapod, and the inner side of described bearing arranges steel bar stress groove, and described steel bar stress groove is made up of vertical plane, indent arcwall face and horizontal plane; The radius of the indent radius of described indent arcwall face and the Reinforcement of reinforcing cage adapts; Along the horizontally set stirrup groove of vertical plane, indent arcwall face and horizontal plane, the radius of the described radius of stirrup groove and the stirrup of reinforcing cage adapts.
As a kind of preferred version of the present utility model, described bearing is the prefabricated units that cement mortar makes.
The beneficial effects of the utility model are: the inner reinforcement location of accurately fixing simply supported beam that this protective device can be simple and effective and the thickness of Control protection layer, thus reduce the displacement of simply supported beam reinforcing bar and the experimental result error caused by topping inaccuracy.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of protective device of protective layer thickness of concrete simply supported beam;
Fig. 2 is the structural representation that reinforcing cage is arranged on the protective device of the protective layer thickness of concrete simply supported beam.
In figure: 1-reinforcing cage; 2-bearing; 3-steel bar stress groove; 31-vertical plane; 32-indent arcwall face; 33-horizontal plane; 4-Reinforcement; 5-stirrup groove; 6-stirrup.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1; a kind of protective device of protective layer thickness of concrete simply supported beam; comprise the bearing 2 being arranged on reinforcing cage 1 tetrapod, the inner side of bearing 2 arranges steel bar stress groove 3, and steel bar stress groove 3 is made up of vertical plane 31, indent arcwall face 32 and horizontal plane 33.The radius of the indent radius of indent arcwall face 32 and the Reinforcement 4 of reinforcing cage 1 adapts; Along the horizontally set stirrup groove 5 of vertical plane 31, indent arcwall face 32 and horizontal plane 33, the radius of the radius of stirrup groove 5 and the stirrup 6 of reinforcing cage 1 adapts.
The prefabricated units that bearing 2 makes for cement mortar, effect is the thickness of the both sides concrete cover controlling beam and supports whole support, can effectively fix reinforcing cage 1, not allow it be shifted.
This protective device can carry out special according to requirements such as the sectional dimensions of beam, the reinforcing cage 1 that bearing completes for supporting colligation.The prefabricated units of its construction size are directly determined by beam section; be positioned over template two ends; reinforcing cage 1 is put on this protective device; just directly can be fixed and (with the position of the inner reinforcing cage of fixing simply supported beam, its Reinforcement 4 and stirrup 6 are fixed with locating; with overall controls local); as shown in Figure 2, with bearing bar cage 1 also fixing next simple and effective control thickness of concrete cover, convenient to operation.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
