Abstract
The invention relates to a mortar hole-injection gun, which solves the problems of time and energy waste, high cost and poor stuffing effect while artificially stuffing as a result of no a building stuffing device for opposite drawing bolt holes currently. The mortar hole-injection gun comprises a tubular gun body, wherein, a front cover board and a back cover board are respectively fixed at the front end and the rear end of the gun body; a funnel communicated with the gun body is fixed on the cylindrical surface at the upper part of the gun body; the back cover plate is penetrated with a piston rod; a piston is arranged on one end of the piston rod in the gun body; the front end surface of the front cover plate is fixed with a cone-shaped tube communicated with the gun body; and the bottom of the funnel is penetrated with a push-and-pull plate capable of separating the cavity of the funnel from the cavity of the gun body. The mortar hole-injection gun fills in the gap that the building stuffing device for the opposite drawing bolt holes does not exist currently; and the gun has the advantages of saving time and energy and realizing full and dense stuffing of motar in the opposite drawing bolt holes, thus eliminating the phenomenon of cold bridge and greatly reducing cost as the motor added by the funnel is not easy to leak.
Description
Technical field
The present invention relates to the tamponade device in split bolt for building hole, be specially a kind of mortar hole-injection gun.
Background technology
Along with the development of building technology, high-layer shear force wall structure dwelling house and public building are more and more in recent years, and most of engineerings adopt the reinforcing of split bolt control shear wall sectional dimension and template in the shear wall concrete construction.Split bolt plays crucial effects to formwork reinforcement, therefore becomes very general and indispensable instrument in the building operations.About every 0.3m on concrete shear force wall
21 split bolt is just arranged, after finishing, concreting forms some split bolts hole, particularly the split bolt hole of exterior wall becomes one " cold bridge " of construction work in energy-conservation, under the overall situation of current " energy-saving and emission-reduction ", must take measures the split bolt hole is handled, but because its sectional dimension is less, stock size is 20, one 25 floor 20000m of φ 14～φ
2The split bolt hole reserved of residential building just reach 68000, therefore slight split bolt hole filling has just had very large difficulty.
When clogged in present split bolt hole, following several method is generally arranged: 1, with scuppit mortar is closed lightly in the hole bit by bit, filling speed was quite slow, has the time-consuming problem of time-consuming expense material; 2, not specially filling, be with trowel band mistake when plastering, what can be filled out just what are filled out, the scope of its filling only limits in the 10mm scope of split bolt aperture, so mortar leakiness, loosening easily, produces very easily herein " cold bridge ", can't reach insulation, heat insulation, sound insulation effect, and outdoor rainwater also can infiltrate indoorly along the split bolt hole, and the problem that causes body of wall humidity, wall skin to come off influences user's dwelling environment.
Summary of the invention
Existence was wasted time and energy when the present invention manually clogged in order to solve the tamponade device that does not have a kind of split bolt for building hole at present, cost is high and the problem of filling weak effect, and a kind of mortar hole-injection gun is provided.
The present invention adopts following technical scheme to realize: mortar hole-injection gun, comprise tubulose rifle body, the rear and front end of rifle body is fixed with front shroud and back shroud respectively, be fixed with the funnel that communicates with it on the face of cylinder on rifle body top, be installed with the end that piston rod and piston rod be positioned at the rifle body on the back shroud and be provided with piston, be fixed with the conical pipe that communicates with the rifle body on the front shroud front end face, the bottom of funnel is installed with the draw back plate that the cavity of the cavity of funnel and rifle body can be separated.During work, mortar is added in the funnel, mortar flows in the rifle body from funnel then, at this moment draw back plate is pushed to, the promotion piston rod travels forward, the effect that piston is subjected to piston rod is squeezed to conical pipe with the mortar in the rifle body, injects the split bolt hole then, have time saving and energy saving, cost is low and clog effective advantage.
The face of cylinder of piston rod is provided with screw thread, and be fixed with the nut that is connected with piston rod thread on the back shroud, driving piston by the rotary-piston bar pushes mortar, more laborsaving quick, improve the squeezing effect of piston, and when first split bolt hole is clogged, calculated the number of turns that the filling of split bolt hole is completely needed the rotating piston bar, when more remaining split bolt hole being clogged, only need to rotate the filling effect that the required number of turns can guarantee the split bolt hole.
The rear end of piston rod is fixed with handle, and is when holding the rotation of handle drives piston rod, more laborsaving.
The left and right sides inwall of funnel is fixed with the clamp that contacts with the draw back plate upper surface respectively, when promoting draw back plate, closely contact between clamp and the draw back plate, further improved the sealing between the funnel and rifle body when draw back plate is closed, the mortar when avoiding piston advances forward in the rifle body is squeezed and overflows from funnel.
Piston is to be formed by bolt by rubber tile and the steel plate that is positioned on the rubber tile front and rear surfaces, and the plunger designs of this kind structure not only can satisfy the rigidity requirement of piston, by having improved the toughness of piston, has prolonged the application life of piston.
The piston rod front portion is with the brace that is fixed on the piston rear surface, and the front end of piston rod is fixed with the flat dop of diameter greater than the brace aperture, when piston rod is rotated forward, the flat dop of piston rod front end withstands piston face and moves, but itself does not rotate piston, has time saving and energy saving advantage in the time of application life of having improved piston.
The present invention has filled up the blank of the tamponade device that does not have a kind of split bolt for building hole at present, not only has time saving and energy saving advantage, and full to the mortar in the internal thread broaching hole, the filling closely knit, eliminated " cold bridge " phenomenon, add mortar by funnel simultaneously and be difficult for omitting, reduced cost greatly; The split bolt hole long with φ 14,200mm is example, through overtesting, comprises mortar is poured into time in the mortar hole-injection gun, but everyone per hour 300 of filling perforations, and bit by bit in the hole, close lightly by original manual filling perforation method, but everyone per hour 25 of filling perforations, filling perforation speed improves 12 times; After institute reaches 28 days the back-up sand slurry time in the mortar hole-injection gun hole simultaneously, nail in the hole with hammer, nail has been bent, but mortar is not moving in the hole, and with syringe at the end in hole along hole wall jetting 2 hours, the water mark does not appear in the other end, and mortar can only be inserted in the internal thread broaching hole about 10mm with the filling perforation method that trowel is plastered, wait to reach 28 days after, one disclose gently with finger, the mortar post has just entered in the hole, does not reach the purpose of filling perforation.
