Detailed Description
The present application is described in further detail below with reference to figures 1-2.
The embodiment of the application discloses novel steel split heads of height-adjustable, refer to figure 1, a novel steel split heads of height-adjustable includes owner muscle 1, support frame 2, flexible muscle 3 and high adjustment mechanism 4, 2 parallel mount on the support frame have a plurality ofly, support frame 2 is the isosceles triangle who forms by three steel bar welding, all install high adjustment mechanism 4 at the top of every support frame 2, 3 vertical installations on high adjustment mechanism 4 of flexible muscle, 1 welding of owner muscle is at the top of many flexible muscle 3. The main reinforcement 1 and the telescopic reinforcement 3 are both made of steel bars on the construction site.
When the interval of reinforcing bar net piece needs to be adjusted, a plurality of height adjustment mechanism 4 of synchronous adjustment adjust the height of main muscle 1 to be applicable to the not upper reinforcing bar of co-altitude.
Referring to fig. 1 and 2, height adjustment mechanism 4 includes a spacing section of thick bamboo 41, auto-lock subassembly 42 and adjusting part 43, and a spacing section of thick bamboo 41 is the hollow cylinder barrel, offers the through-hole 411 that supplies flexible muscle 3 to wear to establish at the both ends coaxial line of a spacing section of thick bamboo 41, and a vertical installation of a spacing section of thick bamboo 41 is on the top of support frame 2, and a spacing section of thick bamboo 41 respectively with the steel bar welding on two edges of support frame 2. The self-locking assembly 42 is arranged in the limiting cylinder 41 and connected with the telescopic ribs 3, and the adjusting assembly 43 is also arranged in the limiting cylinder 41.
Referring to fig. 2, the self-locking assembly 42 includes a self-locking plate 421, the self-locking plate 421 is a steel plate with one inclined end, the inclined lowest end of the self-locking plate 421 is fixedly connected to the inner wall of the limiting cylinder 41, and the inclined highest end of the self-locking plate 421 is abutted to the telescopic rib 3. Two opposite self-locking pieces 421 form a group, and two groups of self-locking pieces 421 are installed in the limiting cylinder 41 and on the same horizontal plane.
The telescopic ribs 3 are made of steel bars on a construction site, the steel bars on the construction site are usually hot-rolled ribbed steel bars, and the surfaces of the steel bars are all provided with bulges distributed at intervals. When the telescopic rib 3 is driven to move upwards along the length direction of the limiting cylinder 41, the telescopic rib 3 and the protrusions on the telescopic rib 3 jack up the self-locking plate 421, the gap between the self-locking plates 421 is enlarged, and the telescopic rib 3 can vertically move upwards; when the telescopic rib 3 moves in place, the self-locking plate 421 abuts against the telescopic rib 3 and the protrusion on the telescopic rib 3, and the telescopic rib 3 is tightly fixed at the current position; when the main reinforcement 1 bears load, the telescopic reinforcement 3 bears downward force, the telescopic reinforcement 3 has a tendency of moving downward along the limiting cylinder 41, at the moment, the protrusion on the telescopic reinforcement 3 is abutted against the top of the self-locking piece 421, and the inclined highest end of the self-locking piece 421 is bent towards the telescopic reinforcement 3, the distance between the self-locking pieces 421 becomes smaller, the telescopic reinforcement 3 is clamped and abutted tightly, and the larger the downward force borne by the telescopic reinforcement 3 is, the firmer the self-locking piece 421 abuts against the telescopic reinforcement 3; thereby be convenient for drive flexible muscle 3 along vertical direction rebound, flexible muscle 3 rebound back that targets in place will stretch out and draw back the muscle 3 fixed chucking automatically at the height that flexible muscle 3 stopped to can bear great power downwards.
Referring to fig. 2, the adjusting assembly 43 includes a sleeve 431 and a shift lever 432, the sleeve 431 is a cylindrical tube, the sleeve 431 is located in the limiting cylinder 41 and is sleeved outside the telescopic rib 3, and an inclined surface attached to the self-locking plate 421 is processed at the top end surface of the sleeve 431; an adjusting hole 412 is formed in the limiting cylinder 41 along the length direction of the limiting cylinder 41, the shifting rod 432 is a cylindrical rod body, the shifting rod 432 extends into the limiting cylinder 41 through the adjusting hole 412 and is fixedly connected with the sleeve 431, the shifting rod 432 is horizontally arranged, and a handle 433 is installed at one end, located outside the limiting cylinder 41, of the shifting rod 432.
Referring to fig. 2, a spring 5 is installed in the limiting cylinder 41, the spring 5 is sleeved on the telescopic rib 3, one end of the spring 5 is fixedly connected with the bottom of the sleeve 431, and the other end of the spring 5 is fixedly connected with the inner bottom wall of the limiting cylinder 41. The spring 5 causes the sleeve 431 to always have a tendency to move away from the stop piece.
When the length direction of the required flexible muscle 3 along spacing section of thick bamboo 41 moves down, the length direction rebound that holds handle 433 along adjusting hole 412 drives sleeve 431 rebound for sleeve 431 top and auto-lock piece 421 are contradicted towards the ground side, and will lift from the slope highest point of locking plate 421, and the gap grow between the auto-lock piece 421, flexible muscle 3 can freely move on vertical direction. The spring 5 enables the sleeve 431 to always have the tendency of moving away from the limiting piece, so that the phenomenon that the handle 433 is touched by mistake in actual production to cause unlocking of the self-locking piece 421 is avoided to a certain extent.
The implementation principle of this application embodiment a height-adjustable's novel steel split heads is: the telescopic ribs 3 are driven to move upwards along the vertical direction, the inclined highest ends of the self-locking plates 421 are jacked up, gaps among the self-locking plates 421 are increased, and the telescopic ribs 3 can move upwards freely; after the telescopic rib 3 stops moving, the self-locking plate 421 abuts against the telescopic rib 3 and the protrusion on the telescopic rib 3, so as to fix the telescopic rib 3 at the current position; when the main rib 1 is loaded, the telescopic rib 3 is stressed by a downward force, the telescopic rib 3 has a downward moving trend, the protrusion on the telescopic rib 3 is abutted against the inclined highest end of the self-locking piece 421, the inclined highest end of the self-locking piece 421 is bent towards the telescopic rib 3, the distance between the self-locking pieces 421 is reduced, and the telescopic rib 3 is clamped and abutted tightly; the handle 433 is pulled upwards, the sleeve 431 lifts the inclined highest end of the self-locking piece 421, the gap between the self-locking pieces 421 is enlarged, and the telescopic ribs 3 can freely move in the vertical direction.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
