Detailed Description

As shown in the figure: this embodiment invisible joint seam and hoist and mount hole site steel fiber concrete pavement board and assembled road surface, including panel body 1, transversely be provided with preformed hole 2 on the panel body, the lateral wall intercommunication of preformed hole and the horizontal both sides of panel body. After the panel body is spliced to form the pavement, the longitudinal direction of the panel body is consistent with the length direction of the pavement, and the transverse direction of the panel body is consistent with the width direction of the pavement; as shown in fig. 1, the panel body is a prefabricated steel fiber concrete structure, two preformed holes which are transversely communicated are longitudinally arranged on the panel body, the preformed holes are formed in a reserved mode when the panel body is poured through concrete, the arrangement of the preformed holes cannot damage the upper surface structure of the panel body, namely the flatness of a road surface is not influenced, and the problem that the flatness of the road surface is reduced due to the fact that hoisting holes are reserved on the upper surface of the panel body is solved; in addition, the preformed hole can be used as a hidden hoisting hole, and the preformed hole does not need to be processed in the later period, so that the construction process is simplified; the preformed hole can be used as a hoisting hole, is beneficial to hoisting and assembling the panel body, solves the problem that the assembly type pavement panel is difficult to install, disassemble and hoist, and is beneficial to improving the construction efficiency; after the hoisting is finished, the transversely spliced panel bodies can be locked by the reserved holes to form a detachable connection structure, so that the assembly and the disassembly of each panel body are facilitated, and the later maintenance of a road is facilitated;

in this embodiment, the longitudinal two side walls of the panel body 1 are respectively provided with a positioning groove 3 and a positioning protrusion 4 which are used in cooperation with each other. The mutual matching of the positioning groove 3 and the positioning bulge 4 means that the positioning groove and the positioning bulge of the adjacent panel bodies are mutually embedded and matched, and the positioning groove and the positioning bulge on the same panel body 1 do not have a matching use relationship; in the process of splicing the panel bodies, the positioning bulges of one panel body are embedded into the positioning grooves of the other panel body, so that the assembly precision between the panel bodies is improved, and the connecting gap between the adjacent panel bodies can be reduced;

in this embodiment, a pipe 5 is embedded in the panel body 1 in the transverse direction to form a prepared hole. The corresponding pipeline is pre-buried in panel body pouring process, and the pipeline adopts the pipe, and the pipeline can be for PVC pipeline or steel pipe, has both done benefit to the shaping of preformed hole through the pipeline, also as the skeleton in the preformed hole, improves the structural strength and the rigidity of preformed hole department.

In the embodiment, a channel steel I6 is pre-embedded in one longitudinal side of the panel body 1, and a positioning groove 3 is formed outwards in a notch of the channel steel I. Combine fig. 6 to show, at the pre-buried channel-section steel I of panel body lateral part in pouring panel body forming process, do benefit to the shaping of constant head tank, I structural strength of channel-section steel itself is greater than the concrete moreover, at adjacent panel body concatenation in-process, does benefit to the structural strength and the support performance that improve seam crossing.

In this embodiment, the vertical opposite side fixedly connected with channel-section steel II 7 of panel body 1, II bulges in panel body lateral wall and notch inwards form the location arch in the channel-section steel. Combine fig. 6 to show, the whole height of channel-section steel II 7 is less than the height of channel-section steel I6 notch for II 7 of channel-section steel can be embedded in I6's notch, cooperation through I6 of channel-section steel and II 7 of channel-section steel improves constant head tank and the bellied structural strength in location and plastic deformation ability, after the two cooperation extrusion, can still keep complete structural style, do benefit to the later stage and dismantle the after-maintenance secondary assembly, the inslot of channel-section steel is the arc angle in addition, can reduce stress concentration phenomenon, prevent that the constant head tank from being conquamated.

In this embodiment, connecting pieces 8 are pre-embedded in the panel body 1 near the longitudinal two sides, and the channel steel I6 and the channel steel II 7 are fixedly connected to the corresponding connecting pieces. Combine shown in fig. 6, the inside anchor reinforcing bar that is close to the position of vertical both sides all pre-buried of panel body, direction of height at the channel-section steel is provided with two rows of anchor reinforcing bars, every row sets up a plurality of anchor reinforcing bars along the length direction of channel-section steel side by side, wherein the anchor reinforcing bar of channel-section steel I6 and corresponding side passes through welded fastening, the tank bottom of channel-section steel II 7 passes through welded fastening with the anchor reinforcing bar of corresponding side, can improve the joint strength of channel-section steel I6 and channel-section steel II 7 and panel body through this structure, and then improve the installation stability of the two.

This embodiment still provides an assembled road surface, the road surface by the aforesaid stealthy seam and the concatenation of hoist and mount hole site steel fiber concrete decking board form, wherein the preformed hole 2 that the panel body of horizontal concatenation corresponds is horizontal just right, and the panel body of horizontal concatenation is through running through the horizontal locking of retaining member in the preformed hole. Combine fig. 2 to show, the road surface of four panel bodies concatenation into field word structure, combine fig. 3 to show, the locking of transversely dismantling is realized through a retaining member in the preformed hole of two adjacent panel bodies, does benefit to the horizontal assembly precision that improves the panel body, improves because the rigidity seam leads to linking up the great problem in gap.

In this embodiment, when the vertically adjacent panel bodies are spliced, the positioning protrusion of one panel body is embedded in the positioning groove of the other panel body. As shown in fig. 5, this structure is advantageous in improving the longitudinal assembling accuracy of the panel body.

In this embodiment, the locking member includes a connecting column 9 sleeved in the preformed hole and locking sleeves 10 screwed at two ends of the connecting column 9, and the locking sleeves 10 lock the transversely spliced panel body transversely. As shown in fig. 3 and 4, in the embodiment, two panel bodies are transversely spliced, the connecting column adopts a steel bar, the external connection of the steel bar is approximately the same as the inner diameter of the preformed hole, the steel bar is used as a connecting piece and also used as a filler filled in the preformed hole, which is beneficial to forming support in the preformed hole, the preformed hole is prevented from collapsing when the pavement is pressed, external threads are arranged at two ends of the steel bar, counterbores at two ends of the preformed hole form a sunken groove for accommodating a locking sleeve, and one end of the locking sleeve is positioned in the sunken groove and transversely presses against the panel body at the bottom of the sunken groove to realize transverse locking of the two panel bodies when the locking sleeve is connected to the steel bar by threads, so that the structure; when three or more panel bodies are transversely spliced, the accurate matching of the panel bodies is realized by increasing the pretightening force of the locking sleeve, which is not specifically described;

in this embodiment, the joint between adjacent panel bodies is filled with an elastic sealing material.
