Description

Technical Field

[0001] The utility model belongs to the technical field of road traffic engineering construction, and specifically relates to a simple tool for grouting prefabricated arched frames. Background Art

[0002] Arched prefabricated skeleton slope protection is a slope protection structure in civil engineering, which has the characteristics of strong bearing capacity, fast construction speed and good durability. It is widely used in slope protection projects such as highways and railways, and can effectively prevent disasters such as collapse and landslides.

[0003] Since on-site pouring requires the arrangement and disassembly of molds, the workload is large and the construction period is long. In order to improve construction efficiency and shorten the construction period, the current construction site mainly produces prefabricated blocks in a centralized manner in the prefabrication yard, transports them to the site with small construction vehicles, and then installs and splices them into an arch structure. After installation, in order to enhance the stability of the arch structure, improve the compressive strength of the material, and prevent the expansion of cracks, it is necessary to grout the gap between the two adjacent prefabricated panels that have been installed. However, at present, most construction workers directly apply grouting agent or cement mortar to the gap and grout the gap between the prefabricated panels. The grouting agent or cement mortar is easy to contaminate the prefabricated panels, affecting the appearance. Utility Model Content

[0004] The utility model aims to solve the above-mentioned problem and provides a simple tool for grouting of prefabricated arch frames, which utilizes a first grouting plate and a second grouting plate spaced apart from each other for auxiliary grouting, so that the grouting agent or cement mortar enters the gap between the prefabricated blocks only from the gap between the first grouting plate and the second grouting plate, i.e., the grouting auxiliary hole, thereby avoiding contamination of the prefabricated blocks.

[0005] The technical problem to be solved by the utility model is achieved by adopting the following technical scheme: a simple tool for grouting a prefabricated arch frame, the prefabricated arch frame comprises a prefabricated block, the simple tool comprises a first grouting plate, a second grouting plate and a pressing handle;

[0006] The first grouting plate and the second grouting plate are arranged at intervals from each other, and the gap between the first grouting plate and the second grouting plate is a grouting auxiliary hole;

[0007] The pressing handle is arranged above the first grouting plate and the second grouting plate, and the pressing handle is connected to the first grouting plate and the second grouting plate respectively;

[0008] The lower surfaces of the first and second jointing plates match the upper surfaces of the prefabricated blocks.

[0009] Preferably, the utility model further includes an auxiliary connecting frame, which is arranged above the first jointing plate and the second jointing plate, and the auxiliary connecting frame is respectively connected to the first jointing plate and the second jointing plate, so as to enhance the strength and stability of the simple tool.

[0010] Preferably, in the utility model, the auxiliary connecting frame is arranged at both ends of the first jointing plate and the second jointing plate, which helps to improve the connection strength between the first jointing plate and the second jointing plate.

[0011] Preferably, the pressing handle of the utility model is arranged in the middle position between the first jointing plate and the second jointing plate, so as to facilitate uniform pressing of the first jointing plate and the second jointing plate so that the first jointing plate and the second jointing plate are fitted on the surface of the prefabricated block.

[0012] Preferably, the pressing handle of the utility model is arched, which is helpful for holding.

[0013] Preferably, the first and second jointing plates of the utility model are formed by stamping steel plates. The steel plates are made into the first and second jointing plates by stamping process, so that the shapes of the first and second jointing plates are consistent with the mold shape of the prefabricated block, so that the first and second jointing plates can be attached to the surface of the prefabricated block, and the jointing agent or cement mortar is prevented from penetrating into the gap between the first or second jointing plate and the prefabricated block to cause pollution.

[0014] Compared with the prior art, the beneficial effect of the utility model is as follows: the utility model utilizes a pressing handle to connect the first grouting plate and the second grouting plate together, and since the lower surfaces of the first grouting plate and the second grouting plate match the upper surface of the prefabricated block, the lower surfaces of the first grouting plate and the second grouting plate can be fitted together with the upper surface of the prefabricated block by pressing the handle, and then the gap between the two adjacent prefabricated blocks can be grouted through the gap between the first grouting plate and the second grouting plate, which can effectively avoid contamination of the prefabricated blocks by the grouting agent or cement mortar.
