Detailed Description
Example 1:
the preferable scheme is as shown in figures 1 to 2, the detachable temporary support for municipal engineering groove construction comprises two side guardrails 1, and a support cross rod 2 is detachably arranged between the side guardrails 1; the edge guard 1 comprises a number of first profile plates 101 and a number of second profile plates 102, which first profile plates 101 and second profile plates 102 are arranged crosswise to each other.
The edge guard 1 is intended to be placed on both sides of the groove and the support rail 2 is intended to be dependent on the width of the groove.
Further, the first profile plate 101 and the second profile plate 102 are both channel steel, and the first profile plate 101 and the second profile plate 102 are perpendicular to each other and are welded and fixed.
Further, the cross brace rod 2 is a hollow steel tube. The hollow steel tube is translated from the end to the middle of the second profile plate 102.
Furthermore, an operation channel is arranged between the two side guardrails 1, the first profile plates 101 are vertically arranged, and the plurality of first profile plates 101 are arranged in parallel; the second profile plate 102 is disposed at the inner side of the operation channel, the second profile plate 102 is open to the inner side of the operation channel, and two end points of the support rail 2 are disposed in the groove of the second profile plate 102.
Example 2:
on the basis of the embodiment 1, the supporting cross rod 2 is improved, and the specific scheme is as follows:
as shown in fig. 3 to 6, the supporting cross bar 2 preferably includes a first concave bar 21 and a second concave bar 22, end portions of the first concave bar 21 and the second concave bar 22 are provided with ear plates, the first concave bar 21 and the second concave bar 22 are hinged to each other, a limiting plate 23 is connected to a bottom surface of a groove of the second concave bar 22, the first concave bar 21 is provided with a limiting member, and the limiting member is used for limiting the limiting plate 23 to rotate; the bottom surface of the groove of the second profile plate 102 is provided with a plurality of convex strips 3.
The support rail 2 is used to press the edge guard 1 against the side wall of the channel, and in embodiment 1, when the support rail 2 is translated from the end portion to the middle portion of the second profile plate 102, the friction force applied to the support rail 2 is large, and the pushing is difficult. In this embodiment, the first concave bar 21 and the second concave bar 22 are bent, the outer ends of the first concave bar 21 and the second concave bar 22 are aligned with the convex strip 3, the first concave bar 21 and the second concave bar 22 are pushed to be in a linear state, and the limit member is used to limit the bending of the support cross bar 2.
