Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and detailed description of the invention of the present utility model is described.
According to the structure of case beam base plate, web reinforcement, controlling base plate, the U-shaped cover reinforcing bar of web and the spacing of horizontal reinforcement well is guarantee the emphasis of reinforcing bar binding quality.In order to control amount of reinforcement and spacing, ensure the quality of products, improve construction speed, the utility model provides a kind of support 10 for prefabricated case beam reinforcing bar binding.As depicted in figs. 1 and 2, this support 10 comprises the base 1 for supporting processed reinforcing bar, and base 1 is extending longitudinally along it, has front-end and back-end, and the upside of base 1 is steel plate, and longitudinal bilateral symmetry of base 1 is provided with support unit.Each support unit comprises at least two inclined strut beams be obliquely installed 2, at least two inclined strut beams 2 are along the longitudinal from the front end interval setting successively to the back-end of base 1, every root inclined strut beam 2 angle of inclination is with respect to the horizontal plane identical, this angle of inclination is different according to processed case beam difference, the lower end of many inclined strut beams 2 is connected with base 1, can be weldingly fixed on base 1, and all tilt to the outside of base.The top of every root inclined strut beam 2 or middle part support to ground by a vertical beam 3, and vertical beam 3 upper end is welded and fixed with corresponding inclined strut beam 2, and lower end supports on the ground.Between adjacent two inclined strut beams 2, level is provided with horizontal shore 4, the position of the upper contiguous both sides of the upper surface (i.e. steel plate) of base 1 is respectively equipped with horizontal shore 5 under row, often the lower horizontal shore 5 of row is weldingly fixed on base 1, extending longitudinally along base 1.As shown in Figure 3, upper horizontal shore 4 and lower horizontal shore 5 are longitudinally respectively equipped with multiple for placing processed reinforcing bar and controlling the groove 90 of bar spacing along it, groove 90 on upper horizontal shore 4 and groove 90 one_to_one corresponding on lower horizontal shore 5, processed reinforcing bar correspondence is placed in groove 90, control the spacing between reinforcing bar by the spacing pre-setting groove 90, this is the position control measure of the U-shaped cover reinforcing bar of case beam.The inclined strut beam 2 and vertical beam 3 of every a pair correspondence are vertically provided with many spaced horizontal pulling reinforcing bars 6.Many horizontal pulling reinforcing bars 6 vertically interval are arranged, and the interval between adjacent two horizontal pulling reinforcing bars 6 sets according to the requirement of processed reinforcing bar, add man-hour directly processed reinforcing bar horizontal support on the horizontal pulling reinforcing bar 6 being positioned at sustained height.The setting that many horizontal pulling reinforcing bars 6 can slide in the horizontal direction, for the processed reinforcing bar that support level is placed.After binding processes the reinforcing bar of prefabricated case beam, need horizontal pulling reinforcing bar 6 horizontally outward pull, take out from support 10 the prefabricated case beam processed upwards is lifted.When reusing, horizontal pulling reinforcing bar 6 is pushed to the inside.This is the position control measure of case beam horizontal reinforcement.
Concrete, the inclined strut beam 2 of every a pair correspondence and vertical beam 3 are all welded with the sleeve pipe 7 that multiple axis horizontal is arranged, as the little steel pipe of well cutting, the multiple sleeve pipes 7 on inclined strut beam 2 and vertical beam 3 respectively vertically interval arrange, the interval of this interval and horizontal pulling reinforcing bar 6 is consistent.Be positioned at sustained height place and be respectively equipped with a sleeve pipe 7, sleeve pipe 7 coaxial line of these two sustained heights on inclined strut beam 2 with on vertical beam 3, the horizontal pulling reinforcing bar 6 highly corresponding with this slides through this two sleeve pipes 7.Conveniently the pull of many horizontal pulling reinforcing bars 6 slides, and adjacent two to three horizontal pulling reinforcing bars 6 can be connected is one group, and level of synchronization is slided.
Further, connected with bottom corresponding inclined strut beam 2 by the first tie-beam 8 bottom every root vertical beam 3; Connected by the second tie-beam 9 between the bottom of adjacent two vertical beams 3.First tie-beam 8 and the second tie-beam 9 are the reinforcing bar of diameter 25mm.
In the present embodiment, inclined strut beam 2 and vertical beam 3 adopt the channel-section steel of 5cm × 5cm, and upper horizontal shore 4 is angle steel with lower horizontal shore 5, and horizontal pulling reinforcing bar 6 adopts the spiral of diameter 12mm.Each support unit is provided with two inclined strut beams, 2, two vertical beams 3.
The concrete construction method of the utility model support is adopted to be: during the reinforcement installation of case beam, first to place U-shaped cover reinforcing bar over the mount 10, the bottom of U-shaped cover reinforcing bar is placed in the groove of lower horizontal shore 5, the side supports of U-shaped cover reinforcing bar, in the groove of upper horizontal shore 4, is fixed by support.Again the reinforcing bar of case beam horizontal distribution is placed on horizontal pulling reinforcing bar 6, carries out colligation to play the effect of fixing whole skeleton with U-shaped cover reinforcing bar.After colligation completes, pull out horizontal pulling reinforcing bar 6 and take out case beam.After adopting this support 10, tied framework reinforcing bar only needs 6 people within 3 hours, to complete the reinforcing bar of a slice case beam with regard to energy colligation.The advantage of this support is when carrying out reinforcing bar binding, U-shaped cover reinforcing bar directly can be placed in respective slot in order, horizontal reinforcement correspondence is placed on horizontal pulling reinforcing bar 6, both saved artificial (helping without the need to manpower), increase work efficiency, the quality of vertical reinforcement spacing can be ensured again.
From the above mentioned, support of the present utility model avoids can assembling reinforcement after the assembling of case beam exterior sheathing supports, and substantially reduces the engineering time, decreases recruitment quantity, improve construction quality.Colligation very specification is put and set up to the reinforcing bar of job site, and the unrest pendulum that largely avoid due to reinforcing bar leaves about the industrial accident caused.Avoid the potential safety hazard with bringing because ground is in bad order in crawler belt hanger program, safety is secure.
The foregoing is only the schematic detailed description of the invention of the utility model, and be not used to limit scope of the present utility model.Any those skilled in the art, equivalent variations done under the prerequisite not departing from design of the present utility model and principle and amendment, all should belong to the scope of the utility model protection.
