Abstract
The utility model discloses a reinforcing bar spacer, which comprises a spacer body. A clamping groove is arranged on the spacer body, bayonets are arranged on the clamping groove, and a groove is arranged at the lower part of the spacer body. Ring-shaped grooves with opposite positions are arranged on the two side walls of the spacer body. The bayonets have a trapezoid shape, and the bayonet positioned on the outer side is larger and that positioned on the inner side is smaller. The reinforcing bar spacer has the advantages of simple structure, easy processing and manufacturing, and high dimensional precision. The reinforcing bar spacer can be installed by only being clamped on the reinforcing bar, without binding, resulting in convenient operation and low time and labor consumption. Due to high dimensional precision and accurate measurement data during construction, the thickness of the poured concrete is uniform and the construction quality is improved. During concrete pouring, the reinforcing bar spacer is pressure resistant and has low liability of fracture.
Description
Technical field
The utility model belongs to the building operations utensil, relates in particular to a kind of bar spacers.
Background technology
In the building iron laying construction, for making concrete the size of reinforcement cover is reached designing requirement, guarantee construction quality, generally adopt the mortar cushion block as locating piece, guarantee that the distance between concrete and the reinforcing bar reaches designing requirement.The preparation method of mortar cushion block is: make the mortar cushion block of different-thickness as locating piece with concrete in advance, on the reinforcing bar that keeps at a certain distance away, the mortar cushion block is fixed on the reinforcing bar lateral surface with steel wire, outerplanar with the mortar cushion block is that benchmark is adjusted template and mortar cushion block distance, will be apart from adjusting to after the designing requirement placing of concrete again.The defective that said method exists is: the mortar cushion block is in uneven thickness in making, and causes the pouring back concrete in uneven thickness, influences construction quality; The mortar cushion block is not withstand voltage in the concrete casting process, easily broken programming and the construction quality of influencing; The method that the mortar cushion block is fixed on the reinforcing bar adopts bundle rich usually, and the method is taken a lot of work, time-consuming consumptive material.
Summary of the invention
It is a kind of rational in infrastructure, easy to operate, reusable that the purpose of this utility model is to provide, more firm building form jig that can template is fixing.
The utility model is achieved through the following technical solutions:
A kind of bar spacers includes the card body, and the top of described card body is provided with draw-in groove, and the draw-in groove place is provided with bayonet socket, and the bottom of card body is provided with groove.
The two side of described card body is provided with the relative annular groove in position.
Being shaped as of described bayonet socket is trapezoidal, and the opening outside being positioned at is bigger, and it is less to be positioned at inboard opening.
Described card body is made of plastics.
The utility model has the advantages that: the utlity model has simple in structurely, be easy to processing and manufacturing, the dimensional accuracy height.The utility model need not bundle as long as it is stuck in promptly finishes installation on the reinforcing bar, and is easy to operate, the saving of labor, saves time.Because it is accurate to measure numerical value in the high construction of dimensional accuracy, make the concrete thickness in pouring back even, improve construction quality.The utility model is withstand voltage in the concrete casting process, is difficult for broken.
Description of drawings
Figure is the utility model structural representation.
The specific embodiment
Embodiment: bar spacers as shown in the figure, include card body 3, the top of described card body 3 is provided with draw-in groove 2, draw-in groove 2 places are provided with bayonet socket 1, and being shaped as of bayonet socket 1 is trapezoidal, and bayonet socket 1 be positioned at the outside opening bigger, it is less to be positioned at inboard opening, makes card body 3 be stuck in difficult drop-off on the reinforcing bar.The bottom surface 6 that to block body 3 during installation contacts with the template medial surface, and the size in the time of can guaranteeing to construct like this between concrete and the reinforcing bar reaches construction requirement, and the bottom of card body 3 is provided with groove 5, and the two side of card body 3 is provided with the relative annular groove in position 4.Above-mentioned groove 5 and annular groove 4 are in order to increase card body 3 and concrete contact area, and concrete can enter wherein when pouring thus, thereby is combined into one securely with stop.Described card body 3 is made of plastics.
