The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The first embodiment is as follows: as shown in fig. 1 and 2, the prefabricated staircase with the pore channels comprises a staircase section plate 1 which is integrally cast, wherein a plurality of pore channels 2 are arranged in the staircase section plate, and the pore channels are distributed from the lower end of the staircase section plate to the upper end in an extending manner. In this embodiment, the cross-section of the duct is circular or oval or square or triangular or other shapes.
The prefabricated stair of foraminiferous way assembled of this embodiment is through setting up the pore on the bench board, and the pore is extended by the lower extreme of bench board toward the upper end and is distributed, so, can effectually alleviate the weight of prefabricated stair of assembled, need not the tower crane of great tonnage, can utilize ordinary loop wheel machine to hoist prefabricated stair of assembled to be convenient for be under construction, conveniently hoist and mount the operation, and improve the efficiency of construction. On the other hand, the prefabricated staircase with the hole channel can also reduce the concrete consumption.
Furthermore, the inclination angle of the pore canal is the same as the gradient of the bench plate. The channels are parallel to each other. The lower end of the pore canal is close to the lower end of the bench plate, and the upper end of the pore canal is close to the upper end of the bench plate.
Furthermore, a plurality of pipelines are embedded in the bench boards, the pipelines extend from the lower ends to the upper ends of the bench boards, and inner cavities of the pipelines form the pore channels. So, be convenient for take the actual production preparation of pore assembled prefabricated staircase.
In a second embodiment, the remaining structure of the present embodiment refers to the first embodiment, and the difference therebetween is that:
as shown in fig. 1 and 2, the prefabricated stairway with the assembled hole further comprises a sectional type pushing device 3. The sectional pushing devices correspond to the pore channels one by one. The upper end of the pore channel 2 is communicated with the upper end of the bench plate, a feed inlet is formed at the upper end of the bench plate, and the lower end of the pore channel is closed. The segmented biasing means 3 are arranged in the corresponding porthole. The sectional pushing device 3 comprises a plurality of sections of push rods 3.1 which are sequentially distributed along the length direction of the pore channel and spiral propelling blades 3.2 arranged on the push rods. Any two adjacent push rods are connected through a push rod connecting structure 3.3. The push rod connecting structure comprises a connecting sleeve 3.31 arranged at the end part of one push rod, one end of the other push rod is inserted into the connecting sleeve, and the connecting sleeve is in interference fit with the push rod inserted into the connecting sleeve. In this embodiment, the push rod and the connecting sleeve on the push rod are coaxially distributed.
When the torque transmitted between the connecting sleeve and the push rod inserted in the connecting sleeve is larger than a set value, the connecting sleeve and the push rod inserted in the connecting sleeve slip.
Further, the segmented biasing device further includes a drive shaft. The upper end of a push rod close to the feed inlet is provided with a plug hole. One end of the transmission shaft lever is inserted into the insertion hole, and the transmission shaft lever can move out of the insertion hole. The transmission shaft lever can not rotate in the connecting hole, and specifically, the cross section of one end of the transmission shaft lever is polygonal, such as a regular quadrangle or a regular hexagon, and the inserting hole is correspondingly polygonal, so that after the one end of the transmission shaft lever is inserted into the inserting hole, the transmission shaft lever can not rotate in the connecting hole. The other end of the transmission shaft lever is provided with a hexagon head or a quadrangle head which is used for being matched with the electric wrench. One end of the transmission shaft rod extends out of the feed port.
The installation method of the prefabricated staircase with the pore passage sequentially comprises the following steps:
firstly, hanging the prefabricated stairway with the hole channel in place;
secondly, injecting the stirred mortar into the corresponding hole channel through the feeding hole, and simultaneously driving a push rod close to the feeding hole to rotate through an electric wrench (specifically, the electric wrench drives a push rod close to the feeding hole to rotate through a transmission shaft rod), so as to drive each push rod in the same hole channel to rotate, so that the mortar near the feeding hole is pushed towards the lower end of the hole channel, and the hole channel is gradually filled with the mortar from the lower end of the hole channel upwards; the mortar of the embodiment is cement mortar;
then, the transmission shaft lever is pulled out;
and thirdly, returning to the second step, and gradually filling the pore passages with mortar in sequence.
The prefabricated staircase with the hole channel can be conveniently hoisted, constructed and installed, and the overall strength, the sound insulation performance and the like of the prefabricated staircase can be guaranteed; specifically, the hole prefabricated staircase of this embodiment is hanging and is put the back in place, pour into the mortar into the pore that corresponds through the feed inlet in, simultaneously, it rotates to drive a push rod that is close to the feed inlet through electric wrench, and then drive each push rod in the same pore and rotate, thereby impel near the mortar of feed inlet toward the lower extreme in pore, and make the mortar up fill gradually by the lower extreme in pore and be full of the pore, after the mortar solidification, each push rod together buries underground in the pore that corresponds, so, it can make things convenient for under the condition of assembled prefabricated staircase hoist and mount construction installation, can guarantee assembled prefabricated staircase's bulk strength again, sound insulation performance etc.
On the other hand, in the embodiment, the mortar near the feeding hole is pushed to the lower end of the pore passage by rotating the push rod, so that the pore passage is gradually filled with the mortar from the lower end of the pore passage to the upper end, and thus, the mortar can be gradually compacted in the pore passage from bottom to top, the compactness of the mortar in the pore passage is ensured, and the overall strength, the sound insulation performance and the like of the stair are ensured; however, in this process, after the mortar at the lower end portion of the pore channel is extruded and compacted, the push rod and the spiral propelling blade at the lower end portion of the pore channel are locked by the compacted mortar and cannot rotate, so that the mortar cannot be smoothly input into the pore channel, and the upper portion of the pore channel cannot be filled with the mortar; in order to solve the problem, the push rod connecting structure is arranged, when the torque force transmitted between the connecting sleeve of any one push rod connecting structure and the push rod inserted in the connecting sleeve is larger than a set value, the connecting sleeve and the push rod inserted in the connecting sleeve slip, so that after the mortar at the lower end part of the hole channel is extruded to be compact, the push rod at the lower end part of the hole channel and the spiral propelling blade are clamped by the compact mortar, and the slip occurs between the connecting sleeve between the clamped push rod and the push rod above the adjacent push rod and the push rod inserted in the connecting sleeve, so that the push rod above the clamped push rod can normally rotate, the mortar near the feeding port is propelled into the hole channel, and the mortar is filled in the hole channel and the compactness of the mortar in the hole channel.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and all simple modifications, alterations and equivalents of the above embodiments according to the technical spirit of the present invention are still within the protection scope of the technical solution of the present invention.
