Detailed Description
The invention will be further explained with reference to the following figures and examples:
first embodiment
Referring to fig. 1-4, this cushion includes concrete cushion 1, concrete cushion 1 is concrete placement forming structure, and vertical reinforcing bar 2 has been buried to the upside of concrete cushion 1, and the lower extreme of vertical reinforcing bar 2 is located concrete cushion 1, and concrete cushion 1's inside is buried horizontal steel sheet 2a with the lower extreme welded of vertical reinforcing bar 2, and horizontal steel sheet 2 a's area is less than the cross-sectional area of concrete cushion 1, and vertical reinforcing bar 2 is welded the horizontal reinforcing bar 3 that is higher than concrete cushion 1 near the lower part of concrete cushion 1. When building construction, concreting, usable concrete tails preparation is with the concrete cushion 1 of reference numeral, and this cushion can adopt concrete placement shaping in the mould of prefabricating the regularization, and intensity is higher.
For the sake of simplicity and clarity of illustration, only one riser G and one cushion block of the formwork J are shown in fig. 3 and 4.
The working principle of the cushion block is as follows:
when a formwork support J of the inclined stepping template B1 of the two running stairs is erected, a cushion block is arranged at a corresponding position of each vertical pipe G of the formwork support J on the inclined stepping template B2 of the next running stair, the vertical steel bars 2 and the vertical pipes G which correspond to the positions are sleeved inside and outside, the lower ends of the vertical pipes G are in contact with corresponding horizontal steel bars 3, each vertical pipe G cannot move randomly and is limited in the height direction, and the adjacent vertical pipes G form a whole through horizontal connecting rods, so that the inclined stepping template B2 of the next running stair can be effectively stressed, the formwork support forming effect of the formwork support J is good, and the instability of the formwork support J can be prevented; concrete is poured on the inclined step template B2 of the next stair and is solidified and formed, the formwork support J is removed, the exposed section (generally with the height of about 20-30mm) of the vertical steel bar 2 outside the concrete is cut off, and the depth of the vertical steel bar G embedded into the concrete can be effectively limited by the arrangement of the horizontal steel bar 3.
The cushion block has the beneficial effects that:
by adopting the cushion block, the formwork support J of the inclined step formwork convenient for climbing the two-run stair is used for formwork support, the vertical pipe G of the formwork support J is easy to detach, and the formwork support is efficient, stable and reliable.
Second embodiment
Referring to fig. 5 and 6, this cushion includes concrete cushion 1, concrete cushion 1 is concrete placement forming structure, vertical reinforcing bar 2 has been buried to the upside of concrete cushion 1, the lower extreme of vertical reinforcing bar 2 is located concrete cushion 1, the inside of concrete cushion 1 is buried horizontal steel sheet 2a with the lower extreme welded of vertical reinforcing bar 2, horizontal steel sheet 2 a's area is less than concrete cushion 1's cross-sectional area, vertical reinforcing bar 2 is close to the lower part of concrete cushion 1 and has been welded horizontal reinforcing bar 3 that is higher than concrete cushion 1, the lower part of vertical reinforcing bar 2 is less than horizontal reinforcing bar 3 department and has been welded strengthening rib 5, strengthening rib 5 runs through the upside and the welding of horizontal steel sheet 2a of concrete cushion 1. When building construction, concreting, usable concrete tails preparation is with the concrete cushion 1 of reference numeral, and this cushion can adopt concrete placement shaping in the mould of prefabricating the regularization, and intensity is higher.
The quantity of vertical reinforcing bar 2 is 2, and two vertical reinforcing bar 2 interval parallel arrangement, two horizontal reinforcing bar 3 are parallel to each other and equal height, weld between the lower part of two vertical reinforcing bar 2 and arrange and equal height's with two horizontal reinforcing bar 3 pull rod 4, pull rod 4 is mutually perpendicular with two horizontal reinforcing bar 3 respectively.
The quantity of the reinforcing ribs 5 at the lower part of any vertical reinforcing steel bar 2 is 3, the three reinforcing ribs 5 at the lower part of any vertical reinforcing steel bar 2 are uniformly distributed along the circumferential direction of the vertical reinforcing steel bar 2, and all the reinforcing ribs 5 are the same in shape and are right-angled triangles.
The working principle of the cushion block is as follows: is substantially the same as the first embodiment, and is not described in detail here.
The two vertical steel bars 2 corresponding to the positions are sleeved with each corresponding vertical pipe of the formwork support from inside to outside, so that each corresponding vertical pipe cannot move randomly, and the constraint capacity of the cushion block on each corresponding vertical pipe can be effectively improved; the arrangement of the pull rod 4 can improve the transverse stability of the two vertical steel bars 2; the three strengthening rib 5 of arbitrary vertical reinforcing bar 2 lower part, circumference equipartition can improve the intensity of this vertical reinforcing bar 2, makes this vertical reinforcing bar 2 obtain better circumference and supports.
