Embodiment 1

[0043] Embodiment one, such as image 3 ,Such as Figure 4 As shown, a certain floor of the concrete cushion 17 has been prepared according to the "railway" laying method, and the position of the hole on the concrete cushion 17 is determined. The hole spacing on the angle iron 12 is 1900mm. Therefore, the concrete pad 17 is also dimensioned according to this.

Embodiment 2

[0044] Embodiment two, such as image 3 Figure 4 and Figure 5 As shown, a drill bit with a diameter of 12mm is used to drill holes according to the lofting position, and then the unthreaded end of the bolt 11 with a diameter of 14mm and welded with a supporting steel bar 15 is nailed into the concrete cushion 17. If the bolt 11 and the concrete cushion If there is looseness between the holes on the 17, nail it into the holes on the concrete cushion 17 for reinforcement, then screw the adjusting nut 14 on the threaded end of the bolt 11, and then screw 12 sets of angle irons that are punched. On the bolt 11, the fixing nut 13 is screwed on the bolt 11 at last. At this time, two angle irons 12 that are 6m long and have holes drilled according to the spacing of 1900mm in advance are placed on each bolt 11 that is nailed in after lofting. The angle iron 12 big samples of " rail formula " at that time just make and place and finish.

Embodiment 3

[0045] Embodiment three, such as image 3 , Figure 4 and Figure 5 As shown, a level is used to level the angle iron 12, and the surveyor uses the level to level the angle iron 12. The construction personnel lift and adjust the nut 14 according to the surveyor's instructions, and adjust the height of the angle iron 12 (the adjustment must be made for each bolt. 11 should be well prepared), so that each angle iron 12 is on the same horizontal plane. Generally, the laying of "railway type" angle iron 12 is set to 5m between two angle irons 12, so that the 6m ruler can be used for leveling Two angle irons 12 are on the same horizontal plane, and at this moment, the elevation point is just checked and passed.

Abstract

The invention relates to a control method for evenness and elevation of large-area abrasion-resistant ground. A device for the control method comprises a bolt provided with screw thread at one end and without screw thread at the other end and welded on a bearing bar, a fixing nut, an adjusting nut, and at least two angle irons with a length of 6 meters and drilled with holes at intervals of 1,900 millimeters. The control method comprises the following steps: lofting a concrete cushion layer, drilling a hole on the concrete cushion layer according to the lofting position, nailing the end without the screw thread of the bolt in the hole of the concrete cushion layer, screwing the adjusting nut at the end with the screw thread of the bolt, sleeving the drilled angle irons on the bolt, screwing the fixing nut on the bolt, levelling the angle irons by using a level gauge, adjusting the adjusting nut to adjust the height of the angle irons, tightening the fixing nut to fix the angle irons, casting ground concrete, levelling the ground concrete cushion layer by using a guiding rule of 6 meters, removing the angle irons, paving an abrasion-resistant surface layer which is polished to be even by a fan polisher and finished by a finisher, and maintaining. The method has the advantages of simplicity, simple facilities, high precision of ground control and remarkable effect.

Description

technical field [0001] The invention relates to a method for controlling the flatness and elevation of a large-area wear-resistant floor, in particular to a method for controlling the elevation by using specific elevation control bolts and cooperating with angle irons, which belongs to the technical field of floor construction. Background technique [0002] The floors of large-scale workshops and underground garages in construction projects often use wear-resistant floors, and the requirements for their flatness and elevation are also very high. Generally, the surface flatness is required to be ≤ 2mm, and the elevation is ≤ 10mm. Therefore, during construction It is very difficult to control the flatness and elevation. In the prior art, fine stone concrete is usually used to punch bars at 5m intervals, and a 6m ruler is used to control the leveling at preset elevations. Such as figure 1 and figure 2 It is the section view of the floor after construction using the prior a...
