Abstract
The utility model discloses a kind of cast-in-situ stair plate cushion block specials, including be parallel to each other horizontally disposed upper transverse bar and lower transverse bar, and the upper and lower transverse bar is half elliptic structure；Multiple vertical bars are welded with from left end to right end interval between upper and lower transverse bar, the lower end of each vertical bar extends downwardly out the lower section of lower transverse bar；Gap section has been cut respectively in the middle part of lower transverse bar between two neighboring vertical bar.The utility model advantage embodies in the following areas: 1, in staircase boards cast-in-place construction, being supported using the cushion block special to staircase boards reinforcing bar, it can be ensured that the thickness of cast-in-situ stair plate and the thickness of cover to reinforcement, construction is simple avoid worker operation fault.2, there is extremely strong stability, deform phenomenon after will not trampling.3, uniform force, leads that force mode is good, ensure that the load-bearing ability that staircase boards reinforcing bar will not bend with stair.4, solve the problems, such as to be staggered because of displacement staircase boards reinforcing bar leakage muscle caused by plate muscle abutting template.
Description
Technical field
The utility model relates to cushion blocks for building, more particularly, to cast-in-situ stair plate cushion block special.
Background technique
The template that cast-in-situ stair (as shown in Figure 3) uses is usually to be in tilted layout, and also has spiral stairs etc..Steel at the scene
Muscle binding is completed to carry out needing to arrange cushion block before casting concrete, upper and lower layer reinforcing bar is separately guaranteed that reinforcing steel bar bear meets and is set
Meter requires.At the scene since cast-in-situ stair supporting module is to be obliquely installed and mobile personnel is more in construction, so cushion block is put
Postpone easily to trample and topple over phenomenon, in concreting process as vibrated concrete and be subjected to displacement, thus
Cause cover to reinforcement that cannot be guaranteed, the stress and cast-type floor slab construction quality, later period for influencing reinforcing bar can not be drawn
Covering is rescued.
Currently, cast-in-situ stair is mostly supporting steel bar structure carrying out the cushion block of casting concrete arranged, supporting steel bar is used
Reinforcing bar at stair is supported, is supported the upper and lower layer reinforcing bar of cast-in-situ stair at easy supporting steel bar using steel bar meter,
It is laid with cushion block, guarantees cast-in-place stair plate thickness and staircase boards thickness of protection tier.Deficiency present in supporting steel bar structure is:
1, the shape of supporting steel bar is not easy to construct, and easily displacement occurs in the stream of people, and cast-in-situ stair is caused to pour back leak muscle and reinforcing bar protection
Thickness degree is insufficient；2, supporting steel bar field of load is smaller, and the quantity for needing to be arranged is more, if being not provided with sufficient amount of supporting steel bar meeting
Not set position plate muscle bending is caused to reduce the stress performance of reinforcing bar；3, since stair template is to be obliquely installed, supporting steel bar is in people
When trampling or concreting run-off the straight phenomenon often, reduces construction quality or lead to the injury of personnel.
Summary of the invention
The utility model aim is to provide the cast-in-situ stair plate cushion block special of a kind of stable structure, uniform force.
To achieve the above object, the utility model takes following technical proposals:
Cast-in-situ stair plate cushion block special described in the utility model, including be parallel to each other horizontally disposed upper transverse bar and lower cross
Muscle, the upper and lower transverse bar are half elliptic structure；Multiple vertical bars are welded with from left end to right end interval between upper and lower transverse bar,
The lower end of each vertical bar extends downwardly out the lower section of lower transverse bar；Part in lower transverse bar between two neighboring vertical bar
Other section has gap section.
The vertical bar being welded between the left and right end of upper and lower transverse bar is four.
The utility model advantage embodies in the following areas:
1, in staircase boards cast-in-place construction, staircase boards reinforcing bar is supported using the cushion block special, it can be ensured that cast-in-place
The thickness of staircase boards and the thickness of cover to reinforcement, construction is simple avoid worker operation fault.
2, there is extremely strong stability, deform phenomenon after will not trampling.
3, uniform force, leads that force mode is good, ensure that the load-bearing ability that staircase boards reinforcing bar will not bend with stair.
4, solve the problems, such as to be staggered because of displacement staircase boards reinforcing bar leakage muscle caused by plate muscle abutting template.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the overlooking structure diagram of Fig. 1.
Fig. 3 is the cast-in-situ stair structural schematic diagram being in tilted layout.
Fig. 4, Fig. 5 are the use state diagrams of the utility model.
Specific embodiment
It elaborates with reference to the accompanying drawing to the embodiment of the present invention, the present embodiment before being with technical solution of the present invention
It puts and is implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to down
State embodiment.
As shown in Figure 1, 2, cast-in-situ stair plate cushion block special described in the utility model, including be parallel to each other horizontally disposed
Upper transverse bar 1 and lower transverse bar 2, upper and lower transverse bar 1,2 is half elliptic structure；From left end between right end between upper and lower transverse bar 1,2
Every being welded with the first vertical bar 3, the second vertical bar 4, third vertical bar 5 and the 4th vertical bar 6；First vertical bar, the second vertical bar, third vertical bar and
The lower end of 4th vertical bar 3,4,5,6 extends downwardly out the lower section of lower transverse bar 2；In lower transverse bar 2 between adjacent two vertical bar
Portion has cut gap section 7 respectively.
In use, cushion block special is put before the upper and lower layer reinforcing bar binding of staircase boards is completed to carry out casting concrete at the scene
It sets among staircase boards reinforcing bar.As shown in figure 4, staircase boards lower layer reinforcing bar 8 is passed through from gap section 7, it is then as shown in figure 5, horizontal
Rotation cushion block special can be stablized, be firmly supported staircase boards reinforcing bar 8.
In the description of the present invention, it should be noted that term " on ", "lower", "left", "right", " vertical ", "horizontal"
The orientation or positional relationship of equal instructions is to be based on the orientation or positional relationship shown in the drawings, be merely for convenience of the description present invention and
Simplify description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with specific orientation construction
And operation, therefore be not considered as limiting the invention.
