Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, belong to the scope of the present invention.
Fig. 1 and 2 show a schematic structural diagram of a preferred embodiment of the present invention, and fig. 2 shows a sliding concrete pump pipe pedestal 10, which includes a pedestal 120, a horizontal sliding mechanism 110 and a telescopic supporting mechanism 130, where the horizontal sliding mechanism 110 is mainly composed of a concave pipe rack 1101 and a guide rail rack 1102 connected integrally from top to bottom, the guide rail rack 1102 is composed of two guide rails arranged horizontally in parallel and a cross bar vertically connected to the upper portion between the two guide rails, the upper portion of the pedestal 120 is provided with two sliding grooves matched with the guide rails, and the guide rails and the sliding grooves are designed such that the horizontal sliding mechanism 110 can freely slide horizontally relative to the pedestal 120, thereby effectively buffering the impact force of concrete on a pump pipe 20 during pumping. A U-shaped supporting plate for wrapping the pump pipe 20 is fixedly arranged inside the concave pipe frame 1101, and a movable buckle 1103 connected between gaps of the concave pipe frame 1101 is further arranged at the upper part of the U-shaped supporting plate; the retractable supporting mechanism 130 is fixedly connected to the lower portion of the base 120, and the height of the retractable supporting mechanism 130 is adjusted to adapt to the thickness of the cast-in-place slab.
The base 120 in this embodiment is formed by welding two layers of galvanized steel sheets in a two-way overlapping manner, and the whole base is rectangular. The concave pipe frame 1101 of the horizontal sliding mechanism 110 is preferably formed by bending a galvanized steel plate. In terms of material, the galvanized steel sheet has the advantages of corrosion resistance, attractive surface, easiness in soldering, high cost performance and the like.
In a preferred embodiment of this embodiment, the movable buckle 1103 is formed by machining an L-shaped galvanized steel plate, and both ends of the movable buckle are fastened to the left and right sides of the concave pipe frame 1101. After the pump pipe 20 is placed on the concave pipe rack 1101, the movable buckle 1103 of the L-shaped galvanized steel plate can be directly clamped on the side wall of the concave pipe rack 1101 above the pump pipe 20, and the pump pipe can be taken down directly by means of external force after use.
In another preferred embodiment of this embodiment, the movable buckle 1103 is composed of a clamping rod and a bayonet, and one end of the clamping rod is hinged to one side of the concave pipe frame 1101; the other side of the concave pipe frame 1101 fixedly connected with the bayonet piece is matched with the other end of the clamping rod. When the bayonet lock is used, the clamping rod can enter or leave the inside of the bayonet piece through rotating around the hinged point, and the opening and closing of the bayonet lock are realized.
As a further improved design of the embodiment, a U-shaped rubber pad is fixedly arranged on the inner surface of the U-shaped supporting plate. The rubber pad plays antidetonation antiskid effect, makes the rubber pad bending into the U-shaped, then hugs closely pump line 20, guarantees the antiskid antidetonation effect of bracket better. In order to optimize and improve the anti-skid performance in a further step, uniformly distributed particle bulges or strip-shaped bulges vertical to the horizontal direction are formed on the surface of the U-shaped rubber pad.
In this embodiment, the retractable supporting mechanism 130 includes a plurality of retractable supporting rods uniformly distributed at the lower part of the base 120. More specifically, the telescopic adjustable support rod comprises a threaded rod 1302 and a steel pipe 1301 which are in threaded fit, and the upper end part of the threaded rod 1302 or the steel pipe 1301 is connected with the base 120 into a whole.

Preferably, the legs 1303 may be designed as flat plates.
As shown in fig. 1, before use, the overall height of the sliding concrete pump pipe support 10 is adjusted by using the lower telescopic supporting mechanism according to the thickness of the slab surface to be poured to ensure that the sliding concrete pump pipe support 10 can be stably supported on the slab bottom formwork, then the movable buckle 1103 on the upper portion of the sliding concrete pump pipe support 10 is opened, the pump pipe 20 is placed on the rubber pad of the concave pipe rack 1101 as required to be fixed, then the movable buckle 1103 is clamped to perform concrete pouring, and the impact force of the concrete on the pump pipe 20 in the pouring process is buffered by using the horizontal sliding mechanism 110.

Through application tests, after the sliding concrete pump pipe support base 10 is used, the average qualification rate of the thickness of the upper layer steel bar protection layer of the plate surface within the radius range of 1 meter of the support base is increased to 90 percent from the original traditional 70 percent.
The economic benefit is mainly calculated as follows:
(1) total cost of cutting machinery and test input: 4100 yuan
(2) The cost is saved:
the process is assumed to be used by 5 monomers in total in the test project, the average layer of each building is calculated according to 10 layers, and the unit cost of labor is 300 yuan/working day. Through on-site actual measurement and data statistics, the steel bar protection layer needs 2 working days for each layer on average. The total cost is saved: 2 x 300 x 10 x 5 30000 yuan, project direct economic benefit: the total cost is saved, namely 30000 yuan to 4100 yuan to 25900 yuan.
