[0003] The utility model aims at the defects of prior art, provide a kind of cable trench mouth Z type steel laying positioning device.
[0004] To achieve the above object, the utility model can adopt the following technical solutions:
[0005] The cable trench mouth Z type steel laying positioning device, including the positioning cross brace of horizontal cross in two Z type steels, a pair of net width positioning members for clamping between two Z type steels is fixedly connected on the bottom surface of the positioning cross brace, the horizontal clamping plate for clamping Z type steel is connected on the bottom surface of the positioning cross brace outside two net width positioning members by bolt assembly, a pair of mounting brackets are fixedly connected on the side of the positioning cross brace, vertical screw rod for leveling positioning cross brace is screwed on two mounting brackets respectively.
[0006] Further, the positioning cross brace is composed of vertical fixed horizontal bottom plate and vertical vertical plate, at this time, net width positioning member is vertically fixed on the bottom surface of horizontal bottom plate, mounting bracket is vertically fixed on the back side of vertical vertical plate (i.e. the other side opposite to horizontal bottom plate), and bolt assembly is vertically passed from horizontal bottom plate, so that the top surface of horizontal clamping plate and the bottom surface of horizontal bottom plate form clamping part, and the upper roof of Z type steel can be stably clamped.
[0007] Further, pad can be provided between the horizontal clamping plate and the bottom surface of the positioning cross brace, the thickness of the pad should be consistent with the thickness of the upper roof of Z type steel, so that the horizontal clamping plate can horizontally clamp the upper roof of Z type steel.
[0008] Further, for the convenience of operation, a screwing handle can be fixedly connected to the upper end of each vertical screw rod, and the axis of the screwing handle should be perpendicular to the axis of the vertical screw rod, so as to facilitate the screwing adjustment of the vertical screw rod by gripping the screwing handle.
[0009] The utility model discloses the advantage lies in through the horizontal cross bracing of positioning of two Z -shaped steel, thereby make the net width positioning piece of setting on the positioning of horizontal cross bracing can be blocked in two Z -shaped steel between net width positioning, simultaneously still utilize the horizontal clamping plate of setting on the positioning of a pair of horizontal cross bracing to clamp two Z -shaped steel, guarantee Z -shaped steel when paving position fixed, afterwards can utilize vertical screw rod to adjust the height of positioning of horizontal cross bracing, and then ensure the flatness of two Z -shaped steel, whole device can be repeatedly used, need not weld the auxiliary angle steel between two Z -shaped steel, save the process of follow -up cutting auxiliary angle steel and polishing treatment, reduce the operation difficulty of Z -shaped steel paving, reduce manpower, material resources investment, guarantee the paving quality, improve the paving efficiency. BRIEF DESCRIPTION OF DRAWINGS
[0010] Figure 1 It is the structural schematic diagram of the utility model.
[0011] Figure 2 It is Figure 1 rear view.
[0012] Figure 3 It is Figure 1 left view (Z -shaped steel is hidden). DETAILED DESCRIPTION
[0013] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0014] As Figures 1-3The utility model discloses a cable trench mouth Z type steel laying positioning device, including the horizontal cross support of being horizontally crossed on two Z type steel 100, is fixedly connected with a pair of net width positioning piece 2 for the card stop between two Z type steel 100 on the bottom surface of positioning cross support 1, the bottom surface on the outer side of two net width positioning piece 2 is connected with a pair of horizontal clamping plate 4 for the clamping fixed Z type steel 100 through the bolt assembly 3 of being threaded on it, is fixedly connected with a pair of mounting bracket 5 on one side of positioning cross support 1, respectively screwing threaded with the vertical screw rod 6 for the leveling positioning cross support 1 of being threaded on two mounting bracket 5, for the convenient operation, still can be fixedly connected with a screwing handle 7 on the upper end of each vertical screw rod 6, the axis of this screwing handle 7 should keep perpendicular with the axis of vertical screw rod 6, thereby conveniently grasps screwing handle 7 to screw the vertical screw rod 6.
[0015] Specifically, positioning cross support 1 is composed of vertically fixed horizontal bottom plate 1.1 and vertical stand 1.2, which can be cut from angle steel of 50*50*5mm according to actual conditions. At this time, net width positioning piece 2 and mounting bracket 5 can also be cut from angle steel of 50*50*5mm. Net width positioning piece 2 is vertically fixed on the bottom surface of horizontal bottom plate 1.1, and mounting bracket 5 is vertically fixed on the back side of vertical stand 1.2 (i.e. the other side opposite to horizontal bottom plate 1.1). Bolt assembly 3 (composed of bolt and nut) is vertically threaded from horizontal bottom plate 1.1, so that a clamping part is formed between the top surface of horizontal clamping plate 4 and the bottom surface of horizontal bottom plate 1.1, which can stably clamp the top plate of Z type steel. In addition, a pad plate 8 can be arranged between horizontal clamping plate 4 and horizontal bottom plate 1.1. The thickness of pad plate 8 is consistent with the thickness of the top plate of Z type steel 100, so as to ensure that horizontal clamping plate 4 can horizontally clamp the top plate of Z type steel 100.
[0016] During use, positioning cross support 1 is horizontally crossed on two Z type steel 100 along the width direction of cable trench, and the two net width positioning pieces 2 arranged on positioning cross support 1 are just correspondingly clamped on the inner side of the connecting stand plates of two Z type steel 100. Meanwhile, the top plates of two Z type steel 100 are clamped and fixed by the pair of horizontal clamping plates 4 arranged on positioning cross support 1, so as to ensure that the positions of two Z type steel 100 are fixed during laying, and the net width meets the laying standard requirements. Then, two vertical screw rods 6 can be used to level positioning cross support 1, so as to ensure that the flatness of two Z type steel 100 meets the laying standard requirements, and it is not necessary to weld auxiliary angle steel between two Z type steel 100 during construction process, thereby omitting the subsequent processing procedures of cutting auxiliary angle steel and polishing Z type steel 100, reducing the laying operation difficulty of Z type steel 100, saving manpower and material resources, ensuring laying quality, improving laying efficiency, and additionally, the whole cable trench mouth Z type steel laying positioning device can be easily disassembled and repeatedly used, thereby reducing the investment of processing and manufacturing cost.
