Please note that, in order to clearly show the structure of the components of the embodiments of this utility model, the drawings are not drawn to the same scale. The same reference numerals are used to indicate the same parts.
[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The embodiments described are only for explaining this utility model and are not intended to limit the scope of this utility model. The following description, in conjunction with... Figs. 1-2 The preferred embodiments of this utility model will be described in further detail below:
[0021] like Figs. 1-2 As shown, this utility model preferably provides a steel stirrup suitable for thin floor slabs. The steel stirrup 4 includes longitudinal stirrup bars 401, transverse stirrup bars 402, and vertical stirrup bars 403. The longitudinal stirrup bars 401, transverse stirrup bars 402, and vertical stirrup bars 403 are perpendicular to each other and connected and fixed at their intersection. The intersection point is located at the junction of the longitudinal and transverse bars of the bottom reinforcement 2 of the floor slab. The longitudinal stirrup bars... 401 is parallel to the longitudinal reinforcement of the bottom reinforcement 2 of the floor slab and is connected and fixed to the longitudinal reinforcement of the bottom reinforcement 2 of the floor slab. The transverse stirrup 402 is parallel to the transverse reinforcement of the bottom reinforcement 2 of the floor slab and is connected and fixed to the transverse reinforcement of the bottom reinforcement 2 of the floor slab. The vertical stirrup 403 is set vertically and has a bent section at the top that bends to one side at 90°. The bent section at the top of the vertical stirrup 403 abuts against the bottom end of the transverse reinforcement of the top reinforcement 3 of the floor slab and is connected and fixed to the transverse reinforcement of the top reinforcement 3 of the floor slab.
[0022] There are many small diameter steel bars (6mm~14mm) waste materials in construction site, such as the remaining steel bar end after cutting and scrapped steel bar component, wherein the scrapped bending forming steel bar component cannot be used after straightening, and only the straight steel bar segment in the structure can be cut out for use, in order to fully utilize the short steel bar waste materials on site, the steel bar stirrup 4 formed by the combination of the longitudinal stirrup bar 401, the transverse stirrup bar 402 and the vertical stirrup bar 403 is designed, and the straight segment steel bar in the steel bar waste material can be used as the manufacturing material of the longitudinal stirrup bar 401, the transverse stirrup bar 402 and the vertical stirrup bar 403, and the steel bar stirrup 4 in the form of the combination of straight segment steel bars also reduces the manufacturing difficulty, and ensures that the construction site can be flexibly manufactured according to the requirement.
[0023] In the utility model, the floor bottom bar 2 is supported by the protection layer cushion block 5, and the steel bar stirrup 4 is directly bound on the floor bottom bar 2 to realize fixation, instead of being supported at the bottom die, so that the steel bar rust point in the lower part of the concrete floor in the later stage is avoided, the supporting height of the steel bar stirrup 4 is reduced to a certain extent, and the problem that the bottom end of the steel bar stirrup 4 is easily dislocated in the non-fixed form is also avoided, in order to ensure that the longitudinal stirrup bar 401 and the transverse stirrup bar 402 can be fixed firmly with the floor bottom bar 2, the length of the longitudinal stirrup bar 401 and the transverse stirrup bar 402 is at least 50mm larger than the arrangement spacing of the floor bottom bar 2, so that the longitudinal stirrup bar 401 and the transverse stirrup bar 402 have sufficient lap length with the floor bottom bar 2, and simultaneously, the length of the top bending segment of the vertical stirrup bar 403 is not less than 50mm, so that the vertical stirrup bar 403 can have sufficient lap length with the floor surface bar 3, and of course, in order to ensure that the vertical stirrup bar 403 can form effective support to the floor surface bar 3, the extension direction of the top bending segment of the vertical stirrup bar 403 needs to be perpendicular to the floor surface bar 3 which is fixed therewith;
[0024] In order to improve the structural stability of the steel bar stirrup 4, the longitudinal stirrup bar 401, the transverse stirrup bar 402 and the vertical stirrup bar 403 are preferably connected and fixed by welding, and simultaneously, the steel bar stirrup 4 is bound and fixed with the floor bottom bar 2 or the floor surface bar 3 by using the binding wire 6, considering the convenient installation angle;
[0025] Since the steel bar stirrup 4 in the utility model uses the vertical stirrup bar 403 in the form of single rod to support the floor surface bar 3, and considering that the vertical stirrup bar 403 is made of small diameter steel bar (6mm~14mm) waste material, the bearing capacity is limited, in order to ensure the construction quality, the utility model is applicable to the small thickness structure floor 1 with the thickness of 100mm~250mm.
[0026] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
