Description
Technical Field
The utility model relates to a building technical field specifically is a pile foundation steel reinforcement cage location frock.
Background
The centering of the pile foundation reinforcement cage is an important quality standard in pile foundation construction, the phenomenon that the top deviation of the reinforcement cage exceeds the standard is more found in the construction process, and the centering is a common fault of pile foundation construction quality control, and the existing control method has the following problems:
the positioning of the reinforcement cage is realized through the prefabricated cushion block protective layer, and the method has the following defects: 1. the cushion block receptor has small area and is likely to deviate in a certain direction; 2. the part stretching into the casing at the top of the reinforcement cage cannot play a limiting role, and the top of the reinforcement cage cannot be effectively ensured to be centered.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a pile foundation steel reinforcement cage location frock to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a pile foundation steel reinforcement cage location frock, protects a section of thick bamboo, the setting of protecting on the steel reinforcement cage protects a prefabricated mortar waistband between section of thick bamboo inner wall and the steel reinforcement cage and the fixed reinforcement of fixed this prefabricated mortar waistband, prefabricated mortar waistband sets up to the adaptation and protects a section of thick bamboo and the steel reinforcement cage and reserve the loop configuration of clearance size, and this prefabricated mortar waistband is formed by the concatenation of the concatenation mortar waistband that two semicircle ring symmetric structures set up, be provided with the fixed muscle that runs through its semicircle loop length in the concatenation mortar waistband, the both ends of concatenation mortar waistband all are formed with and are used for realizing two the interface is pieced together to the L shape of concatenation mortar waistband concatenation.
The inner ring surface of the prefabricated mortar waistband is attached to the outer ring part of the steel reinforcement cage, the outer ring surface of the prefabricated mortar waistband is arranged close to the inner wall of the protective cylinder, and a gap which is not larger than 6cm is formed between the prefabricated mortar waistband and the inner wall of the protective cylinder.
And the fixed steel bars are bound on the steel bar cage and connected with the prefabricated mortar belt.
A fixing rib with the diameter of 6mm is arranged in the splicing mortar waistband.
According to the above technical scheme, the utility model discloses an adopt the prefabricated mortar waistband to realize the location to steel reinforcement cage, not only the location is accurate in the centre, and the effect is obvious, and mortar intensity is low simultaneously, the effectual degree of difficulty that reduces the pile head and abolishes, and after abolishing, the mortar material that abolishes has replaced the design and has surpassed and irritated partial concrete, has saved material cost.
Drawings
FIG. 1 is a top view of the present invention;
FIG. 2 is a side sectional view of the present invention;
FIG. 3 is a side sectional view of the mortar belt of the present invention.
In the figure: 1 protects a section of thick bamboo, 2 prefabricated mortar waistbands, 21 concatenation mortar waistbands, 211 piece mouth, 212 fixed muscle, 3 steel reinforcement cage, 4 fixed reinforcements, 5 clearances.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1-3, a pile foundation reinforcement cage positioning tool includes a casing 1 sleeved on a reinforcement cage 3, a prefabricated mortar belt 2 disposed between an inner wall of the casing 1 and the reinforcement cage 3, and a fixing steel bar 4 for fixing the prefabricated mortar belt 2, wherein the prefabricated mortar belt 2 is an annular structure adapted to a size of a gap reserved between the casing 1 and the reinforcement cage 3, and the prefabricated mortar belt 2 is formed by splicing two splicing mortar belts 21 disposed in a semicircular symmetrical structure; meanwhile, in order to prevent the splicing mortar belt 21 from being easily broken, a fixing rib 212 penetrating through the semicircular length of the splicing mortar belt 21 is arranged in the splicing mortar belt 21, and preferably, a fixing rib 212 with the diameter of 6mm is arranged in the splicing mortar belt 21.
It should be pointed out that two concatenation mortar waistbands 21 that have L shape concatenation mouth 211 that this kind of pile foundation steel reinforcement cage location frock adopted can be quick realize the butt joint, the complexity of frock process has been simplified, prefabricated mortar waistband 2 simultaneously does not can effectual restriction steel reinforcement cage 3 position in protecting a section of thick bamboo 1 because inner ring surface laminating steel reinforcement cage 3 sets up, reach good effect placed in the middle, and this prefabricated mortar waistband 2's outer ring surface and protect and reserve between 1 inner wall of a section of thick bamboo and have certain clearance 5, this clearance 5 also belongs to within the error band, the problem that the section of thick bamboo 1 can't embolia that protects that has avoided prefabricated mortar waistband 2 diameter too big and lead to has been avoided. It should be noted that the prefabricated mortar belt 2 described in this embodiment is formed by combining mortar with 6mm of fixed steel bars, and this arrangement can make the prefabricated mortar belt 2 small in strength and easy to break, reduce the difficulty of pile breaking and chiseling, and place the prefabricated mortar belt in the predetermined over-grouting range of pile head of pile foundation, replace concrete, and do not increase material cost.
In specific implementation, an aluminum alloy template is customized according to the appearance of the splicing mortar belt 21, mortar is manually stirred and then formed and hardened in the template, two splicing mortar belts 21 are prepared, and in order to prevent the splicing mortar belts 21 from being broken, a fixing rib 212 with the diameter of 6mm is placed in the splicing mortar belts 21 during prefabrication; make up into the circle with two concatenation mortar waistbands 21, lay in the outside of steel reinforcement cage 3, with fixed reinforcement 4 with two concatenation mortar waistbands 21 ligatures on steel reinforcement cage 3, and keep prefabricated mortar waistband 2's level, then along with steel reinforcement cage 3 transfers to protect in the section of thick bamboo 1, suspend in midair steel reinforcement cage 3 hoist and mount to appointed elevation position through the hoist and mount, when treating the broken stake of pile foundation pouring, break two concatenation mortar waistbands 21, this kind of concatenation mortar waistband 21 not only can play the positioning action placed in the middle in protecting section of thick bamboo 1 promptly, the effect of the broken stake chisel difficulty has been reduced again simultaneously.
The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
