Description
Technical field
The utility model discloses a kind of multifunctional positioning piece for shearing force wall, belong to the building unit technical field.
Background technology
Shear wall structure is a highrise building concrete structure type body commonly used, and shear wall is that penetration concrete is built and formed then by cage of reinforcement peripheral hardware shuttering.Cage of reinforcement comprise double steel mesh reinforcement routinely the spacing of construction requirement be parallel to each other and set up, connect by location hook again between the double steel mesh reinforcement, the junction of location hook two ends and steel mesh reinforcement all is stranded bundle with thin wire, makes the spacing of left and right sides steel mesh reinforcement unanimous between the higher and lower levels.Require the gross thickness of definite good body of wall according to norm of construction after; outside cage of reinforcement, install template; and make template apart from every side bar space equalization; because location hook can only be controlled the spacing position between the double reinforcing bar; and the situation that uncontrollable cage of reinforcement integral body is moved to any lateral deviation of the template left and right sides; so often adopt cast-in-place mortar cushion block according to the distance pad of location hook setting between each location hook and template, guarantee the spacing of steel mesh reinforcement to template, promptly guarantee the thickness of topping.Concrete perfusion in template then, wait concrete strength to reach construction requirement after form removal get final product.Its shortcoming is; build the mortar cushion block and need waste the long time; and the mortar cushion block is stressed to be easy to fragmentation and to come off, and this will influence the thickness of shear wall topping, and this construction member makes the position of shear force wall reinforcing steel bar net and protective layer thickness all be difficult to be guaranteed.In this technical improvement, the existing multi-functional location hook of a kind of shear wall that discloses of Chinese patent net, its number of patent application is: 200720184724.1, and its structure is to be fixed with cushion block on the two end hooks shoulder of location hook, location hook and cushion block adopt and weld or bonding mode is connected.It has simple in structure, has also overcome the defective that is offset about location hook, but it is constructed when locating, need to tie up fixingly with steel mesh reinforcement the two ends of location hook respectively with thin wire, this makes troubles to construction, waste man-hour, this product adopts reinforcement fabrication in addition, and cost is bigger, if adopt the less reinforcement fabrication of diameter, then flexural strength is not enough, will influence construction precision, if select the big reinforcing bar of diameter for use, though reached construction requirement intensity, but the manufacturing cost costliness, thereby strengthen building costs.
The utility model content
The utility model is at the deficiencies in the prior art, and purpose is to provide that a kind of to collect functions such as steel mesh reinforcement location, protective layer thickness and the control of shear wall gross thickness be the multifunctional positioning piece for shearing force wall of one, and has easy construction, advantages such as low processing cost.
The purpose of this utility model is achieved in that a kind of multifunctional positioning piece for shearing force wall, it is characterized in that: comprise backstay, the two ends of backstay are provided with cushion block, and the backstay of two cushion block inboards is provided with grab.
The utility model further is set to:
The shape of described cushion block is the little round platform of outer imperial palace, and its interface shape is an isosceles trapezoid.The section area of cushion block outer end is greater than the section area of backstay, and cushion block is used to withstand template, thereby controls the distance of two side templates shoulder, is used to control the thickness of shear wall in other words.
Described grab is made up of two male type circular arc members of symmetry, and its end pin turns up towards bilateral symmetry respectively, and grab is begun by the drop point of cushion block on backstay at the initial end points on the backstay.After grab 3 blocked the reinforcing bar of steel mesh reinforcement, the reinforcing bar outside was the thickness of topping to the distance of cushion block outer face.Also be provided with circumferentially uniform some man-like shelf reinforcing ribs on the backstay within described two grabs.
The quantity of described man-like shelf reinforcing rib is 3～20, is provided with between the adjacent reinforcing rib to connect the footpath, preferably adopts 4 or 6, uniform setting on the backstay circumference.
The angle of described man-like shelf reinforcing rib is 100～170 degree, and the man-like shelf reinforcing rib is on 0.01～100 millimeter any point behind the drop point of grab at the initial end points on the backstay.
Described backstay, cushion block, grab and reinforcing rib are integral structure, adopt engineering plastics to be made.It is into a single integrated structure that the utility model keeper adopts engineering plastics to be that raw material passes through the equipment demoulding, it is little to have weight, the sixth that under the situation of same structure, is about iron weight, processability is good, the production efficiency height, the corrosion of water-fast and various chemicals, save prior art and need make the operation and the cost of antirust processing with reinforcement fabrication, saved the cost of production of prior art cushion block and main part welding, self lubricity is good, and friction factor is little, is convenient to construction and installation, economize on resources and the energy, reduce cost.
Described backstay is the hollow rod body or the solid body of rod.
After adopting above technical scheme; the beneficial effects of the utility model are: simple in structure, and remarkable to shear wall drawknot, locating effect, and make construction install convenience; effectively control the thickness and the overall thickness of shear wall of shear wall topping, reach the standard of construction requirement.This structure is easy to process, can produce in batches, has prevented the body of wall corrosion phenomena, has guaranteed the attractive in appearance of metope.
Below in conjunction with drawings and Examples the utility model is further described in detail, but is not that the interest field that the utility model is claimed is confined in following examples.
