Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.
As shown in fig. 1 to 4, a cushion block for controlling thickness of protective layers of a beam, a wall bottom and lateral steel bars and positioning main steel bars comprises a cushion block bottom steel bar 1, cushion block side steel bars 3 and a concrete cushion block 2, wherein the cushion block bottom steel bar 1 is arranged in parallel with the width direction of the concrete cushion block 2, the cushion block side steel bars 3 are arranged in parallel with the height direction of the concrete cushion block 2, two cushion block side steel bars 3 are arranged at positions away from two ends of the cushion block bottom steel bar 1 by a certain distance, the cushion block bottom steel bar 1 and the cushion block side steel bars 3 are welded, the cushion block bottom steel bar 1 and the cushion block side steel bars 3 are wrapped by the concrete cushion block 2 to form a bar structure, the cushion block side steel bars 3 are exposed out of the concrete cushion block 2 by a certain.
Specifically, the cushion block is made of on-site concrete pouring residual waste, and the strength grade of the concrete is greater than or equal to that of the concrete at the construction part.
Specifically, the exposed length of the cushion block side rib 3 is 5 cm.
Specifically, the cushion block bottom rib 1 and the cushion block side rib 3 are made of phi 6 or phi 8 steel bars.
Specifically, welded cushion block bottom ribs 1 and cushion block side ribs 3 are placed on the concrete precast slab at equal intervals.
When the cushion block is manufactured: the material for manufacturing the cushion block is made of the residual waste materials of on-site concrete pouring, and the strength grade of the concrete is greater than or equal to that of the concrete at the construction part. In the manufacturing process, concrete is firstly paved and leveled on an empty ground. The paving thickness is determined according to the requirements of the thicknesses of the protective layers at different parts; the cushion block (see figure 1) is prefabricated on site (or in a processing plant), a cushion block bottom rib 1 and a cushion block side rib 3 are welded, and mortar is adopted to wrap the cushion block bottom rib 1 to form a strip-shaped structure. The exposed length of the cushion block side rib 3 is 5 cm. The cushion block bottom rib 1 and the cushion block side rib 3 are made of phi 6 or phi 8 steel bars. The phi 6 or phi 8 steel bars can be made of on-site waste materials, the length of the steel bars leaks by 50mm according to requirements, namely the diameter of the main bar of the extension beam or the distribution bar of the wall is ensured, and the full anchoring length is ensured during binding. And (3) directly placing the finished products welded by the manufactured cushion block bottom ribs 1 and the cushion block side ribs 3 on the concrete precast slab at equal intervals, wherein the placing positions of the cushion block bottom ribs 1 and the cushion block side ribs 3 in the placing process are placed in order, and the finished products are placed in the concrete at the position between the two sides of the thickness of the concrete precast slab. After the cushion block bottom ribs 1 and the cushion block side ribs 3 are placed, the concrete is uniformly divided according to the width required by the cushion block, and the surface is ensured to be flat. And after the strength of the concrete meets the requirement, installing the cushion blocks into the beam and the wall in a partitioning manner.
When the cushion block is applied to the beam 5 (see fig. 1 and 3), the length of the cushion block is the width of the beam, and the cushion block is placed to the bottom of the beam after the beam template is installed. The large beam adopts a construction method of mounting one side template of the beam bottom paved with the steel bar, and the cushion block is placed to the beam bottom after the one side template is mounted. The placement intervals are about 1 meter apart. And binding the beam reinforcing steel bars, binding the beam bottom stress reinforcing steel bars and the cushion block side reinforcing steel bars 3 together to form a whole, and ensuring that the thicknesses of the beam bottom and the beam side protective layer meet the requirements. And after the large steel bars are bound, closing the other side template.
When being applied to wall post 6 (see fig. 4), after the wall post reinforcement is accomplished, place the cushion to tie cushion side reinforcement 3 and post reinforcement together simultaneously, form an organic whole, guarantee the thickness of post tip and side reinforcing bar protective layer. During installation, the cushion block bottom ribs 1 and the cushion block side ribs 33 can be bound with wall column reinforcing steel bars (horizontal ribs and stirrups) or spot-welded, so that the thickness of the protective layers of the wall column end part and the side reinforcing steel bars is ensured.
Based on the above, the invention has the following beneficial effects: (1) erecting the structural steel bars and forming an integral with the structural steel bars, so as to ensure accurate positioning of the stressed steel bars and no deviation; (2) the thickness of the beam bottom (the end part of the wall column) and the lateral steel bar protection layer is ensured; (3) the mortar wraps the steel bars, and the cushion blocks are high in strength and not easy to crush; (4) and the cost is saved by adopting on-site waste steel bar manufacturing.
