Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the invention clearer and easier to understand, the technical scheme of the invention is further explained in the following with the accompanying drawings and the embodiments.
As shown in fig. 1 to 3, an embodiment of the present invention provides a template for a shear key of a steel structure roof support, including a positioning rod 1, a balancing weight 2, and a shaping box 3 capable of accommodating the shear key; an opening is formed in the upper end of the shaping box 3, and the balancing weight 2 is placed in the shaping box 3; locating lever 1 is equipped with a plurality of, and the connection can be dismantled to a plurality of locating lever 1 level in the upper end of stereotype case 3, the one end that stereotype case 3 was kept away from to locating lever 1 is equipped with locating lever 1 fixes the fixed knot structure on the steel construction column cap.
The shaping box 3 provides a space for installing the shear key; the fixing device is characterized in that the fixing rods 1 are arranged and used for fixing the shaping box 3, at least two fixing rods 1 are arranged, and when the number of the fixing rods 1 is two, the end part, which is not connected with the shaping box 3, of each fixing rod 1 is limited on a column head through a fixing structure, so that the movement of the shaping box 3 in the horizontal direction is limited to a certain extent, the movement of the shaping box 3 is avoided, the position can be adjusted on site according to requirements, and the construction size and the accurate positioning of the shear key groove are well guaranteed; the shaping box 3 is detachably connected with the positioning rod 1, so that when the template is disassembled, the positioning rod 1 can be disassembled without disassembling the shaping box 3, and the condition that the template is not completely disassembled easily in the disassembling process is avoided; the fixing structure can be conveniently disassembled and repeatedly utilized for many times, so that the cost is saved; the balancing weight 2 can provide gravity, has played certain effect to the fixed of the position of design case 3 to, balancing weight 2 can play the extrusion to the concrete, not only can avoid former reservation template filler mode probably to cause the space outside, can better guarantee other position concrete compactness except that the shear force key recess.
The length, the width and the length of the groove of the shear key are reduced to manufacture the balancing weight 2 according to the requirement, so that the balancing weight 2 can be conveniently and smoothly placed in the shaping box 3; the shaping box 3 is made of a disassembly-free metal template and can be bound with the positioning rod 1 through a steel wire.
As shown in fig. 1 to 3, fixed knot constructs including slider 41, is equipped with the confession on the slider 41 the through-hole 411 that locating lever 1 passed, the vertical locating plate 42 that has set firmly on slider 41, locating plate 42 is close to one side of stereotype case 3 is close to with slider 41 one side of stereotype case 3 is in the coplanar, be equipped with the external screw thread on locating lever 1, the cover is equipped with position sleeve 43 on locating lever 1, be equipped with in the position sleeve 43 with the internal thread of external screw thread fit, just position sleeve 43 is located slider 41 is kept away from one side of stereotype case 3. The sliding block 41 can move on the positioning rod 1, and the positioning plate 42 is arranged, so that during positioning, the sliding block 41 and the positioning plate 42 are both in contact with the column head and are in threaded fit with the positioning rod 1 through the positioning sleeve 43, and the positioning sleeve 43 and the column head clamp and fix the positioning plate 42 to prevent the positioning rod 1 from driving the shaping box 3 to horizontally move.
As shown in fig. 1, the positioning rod 1 includes two groups of positioning rods fixed vertically, each group of positioning rods includes two positioning rods 1 parallel to each other, the four positioning rods 1 form a structure similar to a shape like a Chinese character 'jing', and the four positioning rods 1 are matched with a fixing structure arranged at the end part, so that the fixing effect can be improved; the four sides of the upper end opening of the shaping box 3 are respectively in one-to-one correspondence and detachably connected below the four positioning rods 1, so that the balancing weight 2 can be conveniently placed.
As shown in fig. 2, the fixed connection of four locating levers 1 below has and holds the positioning reinforcement skeleton 5 of balancing weight 2, positioning reinforcement skeleton 5 is located in the case 3 of finalizing the design. The positioning steel bar framework 5 is manufactured by a steel reduced rule with the diameter of 10mm being 20 mm; when demolising, having demolishd the design case 3 back, through rebound locating lever 1 alright take out positioning reinforcement skeleton 5 together with balancing weight 2, be convenient for remove balancing weight 2.
The invention also provides a method for erecting the template for the shear key of the steel structure roof support, which comprises the following steps:
s1: adjusting the fixing structure to perform primary positioning;
s2: and pouring concrete into the column cap, and reserving the concrete amount of the shear key groove.
S3: placing the shaping box 3 and the positioning steel bar framework 5 in a column head, and adjusting a fixing structure to perform accurate positioning;
s4: placing a balancing weight 2;
s5: and taking out the template.
In the step S1, 30mm is reserved between the positioning plate 42 and the column head during the initial positioning. And a reserved amount is reserved, so that the subsequent positioning is accurately adjusted.
Because in S2 step, can not accurately reserve shear key recess concrete volume, in order to compensate the not enough of concrete volume, in S4 step, after balancing weight 2 placed, the inspection column cap in the concrete condition, in time supply concreting. After the balancing weight 2 is placed, the concrete vibrating rod can be matched to extrude the surrounding concrete, so that the compactness of the concrete is ensured.
In the step S5, the fixing structure is firstly dismantled, then the balancing weight 2, the positioning rod 1 and the positioning steel bar framework 5 are taken out, the shaping box 3 does not need to be taken out, and quality risks that an original template and a filler clamp slag, and the removal is not clean are avoided.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
