Abstract
The invention discloses a building template counter-pulling structure in tension components of building industries. The counter-pulling structure comprises an embedded rod and pull rods. Two ends of the embedded rod are provided with sector retaining blocks in relative symmetry. The tip of each pull rod is provided with a sector protrusion. The size of each sector protrusion is matched with the sector gap between the sector retaining blocks. Counter-pulling is realized by the sector protrusions on the pull rods and the sector retaining blocks on the embedded part. The sector protrusions pass the sector gap between the sector retaining blocks and rotate at a certain angle, the sector protrusions and the sector retaining blocks overlap in the axial direction, counter-pulling of the two pull rods is achieved, and the form plate is stabilized. The building template counter-pulling structure is simple, bolt screwing is avoided during construction, counter-pulling can be achieved by rotating the pull rods less than one circle while bolt counter-pulling rods need to rotate multiple 360 degrees to achieve counter-pulling, construction time is shortened, and construction efficiency is increased.
Description
Technical field
The invention belongs to the tensional element of building trade, be specifically related to construction formwork to pull-up structure.
Background technology
In recent years, China, when the large-scale vertical member concrete pouring constructions such as shear wall, generally adopts and row formwork is tipped in to screw thread, nut and butterfly in pull bar two ends fixes.And to pull bar, need concentrate at the scene the processing of car silk, screw mandrel and nut in use easily damage, get rusty and lose.Because screw rod tooth distance is short, screw thread thin, easy stripped thread, be subject to external force collision flexible, it may cause quality, security incident in formwork loading process.Address this problem, to pull bar two ends, conventionally need to reinforce with double nut and Tripterospermum affine button, during installation fee, take material, effort, efficiency of construction is low.
Summary of the invention
The technical problem to be solved in the present invention is to provide construction formwork that a kind of efficiency of construction is high to pull-up structure.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: construction formwork is to pull-up structure, comprise pre-buried bar and pull bar, the two ends of pre-buried bar are provided with relatively symmetrical fan-shaped block, the termination of pull bar is provided with fan-shaped projection, and the size of fan-shaped projection is mated with the fan-shaped space between fan-shaped block.
Technique scheme realizes drawing by the fan-shaped projection on pull bar and the fan-shaped block on built-in fitting, fan-shaped projection is crossed the fan-shaped space between fan-shaped block, after rotating to an angle, fan-shaped projection and fan-shaped block are overlapping in the axial direction, thereby realize two pull bars to drawing, stablize template, change scenario-frame simple, in work progress, do not need to twist the step of bolt yet, pull bar rotates and can realize drawing less than one week, and bolt to pull bar also need to turn a plurality of 360 degree just can realize drawing, shortened the engineering time, improved efficiency of construction.
As the further restriction of technique scheme, in order to ensure can too much not rotating when the rotating tension bar, at the same side of fan-shaped block or fan-shaped boss, be provided with limited block.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structure diagram of construction formwork of the present invention to pull-up structure embodiment.
The specific embodiment
As shown in Figure 1, construction formwork provided by the invention is to pull-up structure, comprise built-in fitting 1 and pull bar 2, the two ends of built-in fitting 1 are provided with relatively symmetrical fan-shaped block 11, fan-shaped protruding 21 of pull bar 2 one end coordinate with fan-shaped block 11, fan-shaped protruding 21 is also relatively symmetrically arranged, gap between fan-shaped protruding 21 size and two fan-shaped blocks 11 matches, during tension template, by fan-shaped protruding 21 gaps of passing between fan-shaped block 11 of pull bar 2, half-twist and fan-shaped block shaft are to overlaping, thereby realization is to drawing.
Above-described is only the preferred embodiment of the present invention, should be understood that for a person skilled in the art, not departing under the prerequisite of structure of the present invention, can also make some distortion and improvement, these can not affect effect of the invention process and practical applicability.
Claims (2)
1. construction formwork, to pull-up structure, comprises pre-buried bar and pull bar, it is characterized in that: the two ends of pre-buried bar are provided with relatively symmetrical fan-shaped block, and the termination of pull bar is provided with fan-shaped projection, and the size of fan-shaped projection is mated with the fan-shaped space between fan-shaped block.
2. construction formwork according to claim 1, to pull-up structure, is characterized in that: the same side at described fan-shaped block or fan-shaped boss is provided with limited block.
