When the stair formwork supporting base is utilized, the engineering cost can be saved, and the engineering construction speed can be improved.
Description
Technical field
The utility model relates to construction formwork and supports field, more specifically, relates to a kind of stair template base for supporting.
Background technology
In construction work such as concrete engineering construction, because the stair template of frame construction has certain height apart from bottom surface, so need to the stair template of frame construction be supported.
At present, in the stair template support system of frame construction, traditional method for supporting be with steel pipe support on template or with steel pipe support to cement block, if with steel pipe support on template, after can causing concreting to be completed, the steel pipe of Transducers Embedded in Concrete part can't take out, steel pipe to be excised at itself and concrete surface place during stripping, cause the steel pipe waste, and can stay a lot of holes at surface of concrete structure, the later stage can be caused equally waste of material and drag slow engineering construction speed the shutoff in the hole that steel pipe forms; , if to cement block, the intensity of cement block is compared poor with the intensity of cast-in-situ concrete with steel pipe support, and does not guarantee the globality of cast-in-place concrete structure, also affect the quality of reinforced concrete structure the work items.
The utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of stair template base for supporting, after can guaranteeing that concreting is completed, the steel pipe that plays the support shuttering effect can the Transducers Embedded in Concrete member in, also can guarantee the globality of cast-in-place concrete structure.
The stair template base for supporting that the utility model provides, comprise horizontal reinforcing bar, lower horizontal reinforcing bar and vertical reinforcement; Wherein, lower horizontal steel bar welding is connected on an end of vertical reinforcement; Lower horizontal reinforcing bar is fixed on the bottom surface of stair template; Upper horizontal reinforcing bar and lower horizontal parallel reinforced steel bar are welded on the medium position of vertical reinforcement; Be socketed with supporting steel pipe on vertical reinforcement, and the length of upper horizontal reinforcing bar is less than the length of lower horizontal reinforcing bar and greater than the diameter that is socketed in the supporting steel pipe on vertical reinforcement; Distance between upper horizontal reinforcing bar and lower horizontal reinforcing bar is greater than the distance between stair template upper surface and lower horizontal reinforcing bar.
Wherein, preferred scheme is that lower horizontal reinforcing bar is fixed on the bottom surface of stair template by ingot iron.
Wherein, preferred scheme is that lower horizontal reinforcing bar is fixed by welding on the bottom surface of stair template.
Utilize above-mentioned according to stair template base for supporting of the present utility model, supporting steel pipe can be socketed on vertical reinforcement, after concreting is completed, steel pipe can the Transducers Embedded in Concrete member in, do not need excision while removing supporting steel pipe and directly supporting steel pipe is extracted and got final product,, because supporting steel pipe can not stay hole at surface of concrete structure, do not need the later stage manually to add stifled hole, thereby the saving engineering cost, improve engineering construction speed.
Description of drawings
By reference to the content below in conjunction with the description of the drawings and claims, and along with to of the present utility model, understanding more comprehensively, other purpose of the present utility model and result will more be understood and should be readily appreciated that.In the accompanying drawings:
Fig. 1 shows the structural representation according to stair template base for supporting of the present utility model.
Reference numeral wherein comprises: upper horizontal reinforcing bar 1, lower horizontal reinforcing bar 2, vertical reinforcement 3, stair template 4, supporting steel pipe 5.
Label identical in institute's drawings attached is indicated similar or corresponding feature or function.
The specific embodiment
Below with reference to accompanying drawing, specific embodiment of the utility model is described in detail.
Fig. 1 shows the structural representation according to stair template base for supporting of the present utility model.
As shown in Figure 1, the stair template base for supporting that the utility model provides comprises horizontal reinforcing bar 1, lower horizontal reinforcing bar 2 and vertical reinforcement 3, lower horizontal reinforcing bar 2 is welded on an end of vertical reinforcement 3, and by ingot iron or be weldingly fixed on stair template 4 bottom surfaces, upper horizontal reinforcing bar 1 is welded on the medium position of vertical reinforcement 3, and is parallel with lower horizontal reinforcing bar 2.At the supporting steel pipe 5 that also is socketed with on vertical reinforcement 3 for stair template above supporting, the lower end of supporting steel pipe 5 withstands on horizontal reinforcing bar 1.
In order to guarantee that upper horizontal reinforcing bar 1 is not embedded in stair template 4, the distance between upper horizontal reinforcing bar 1 and lower horizontal reinforcing bar 2 is greater than the distance between stair template 4 upper surfaces and lower horizontal reinforcing bar 2, goes up so horizontal reinforcing bar 1 and just can not be embedded in stair template.
Further, in order to guarantee that upper horizontal reinforcing bar 1 can block the supporting steel pipe 5 that is socketed on vertical reinforcement 3 and not be embedded in stair template 4, the length of upper horizontal reinforcing bar 1 is larger than the diameter of the supporting steel pipe 5 that is socketed on vertical reinforcement 2, and supporting steel pipe 5 is because not stopping of upper horizontal reinforcing bar 1 can be embedded in stair template 4 like this.
To bear the weight of top stair template due to lower horizontal reinforcing bar 2, so need to increase the lifting surface area that lower horizontal reinforcing bar 2 contacts with place flat bed stair template 4, guarantee that lower horizontal reinforcing bar 2 can more firmly support the top stair template, therefore, the length of lower horizontal reinforcing bar 2 is greater than the length of horizontal reinforcing bar 1.
The lifting surface area that contacts with supporting steel pipe 5 in order to increase upper horizontal reinforcing bar 1, can make supporting steel pipe 5 stressed more even around the vertical reinforcement 3 several horizontal reinforcing bars 1 of welding, plays better supporting role.
When building the stair template support system of frame construction, first lower horizontal reinforcing bar 2 use of stair template base for supporting definitely are fixed on the bottom surface of stair template 4, brace foundation as whole stair template, again supporting steel pipe 5 is socketed on the vertical reinforcement 3 of stair template base for supporting,, to support the stair template of top, carry out afterwards concreting, after concreting is completed, supporting steel pipe 5 is removed, removed with the reinforcing bar cutting that the angle grinding machine will expose surface of concrete structure finally.
The selection of the upper horizontal reinforcing bar 1 in the stair template base for supporting, lower horizontal reinforcing bar 2 and vertical reinforcement 3 is useless steel bar end, effectively save cost, the making of stair template base for supporting can be carried out at the construction field (site), and is easy and simple to handle, and installation, dismounting speed are fast, high safety.
Accompanying drawing has been described according to the stair template base for supporting that the utility model proposes in the mode of example above with reference to.But, it will be appreciated by those skilled in the art that the stair template base for supporting that proposes for above-mentioned the utility model, can also make various improvement on the basis that does not break away from the utility model content.Therefore, protection domain of the present utility model should be determined by the content of appending claims.
