Description

Technical Field

[0001] The invention relates to the technical field of concrete pouring, in particular to a gate grille device for pouring concrete for stairs and a method for pouring concrete for stairs. Background Art

[0002] At present, most traditional stairs are built by pouring concrete. When pouring concrete for stairs, it is first necessary to install the template according to the size and shape of the stairs to be poured to form a pouring cavity, and then pump the concrete from the upper part of the template to the pouring cavity. When the height of the stairs to be poured is slightly higher, due to the certain height difference of the stairs, the flow rate of the concrete will gradually increase when it flows down from a high place. When the concrete flows to the lowest point, the flow rate quickly drops to zero, which will cause the concrete to accumulate at the bottom of the stairs, and produce a great horizontal tension on the template, causing the template to deform, shift, and break, and even bulge and burst, resulting in serious construction quality accidents, which poses a great threat to the safety and quality of stair concrete pouring.

[0003] The Chinese utility model patent with the authorization announcement number CN205976492U discloses a staircase concrete pouring formwork device, which mainly includes a bottom formwork, two side formworks and multiple transverse baffles. The bottom formwork is a rectangular thin plate, and a plurality of square wooden keels are arranged on the back of the bottom formwork, and the plurality of square wooden keels are arranged along the width direction of the bottom formwork, and two adjacent square wooden keels are arranged at intervals, and the two sides of the bottom formwork are respectively placed between the upper and lower adjacent floor conversion platforms. When in use, the two ends of the bottom formwork are respectively placed on the upper and lower adjacent floor conversion platforms, and the two side formworks are nailed to the two sides of the bottom formwork. The side formwork is also connected to the upper and lower adjacent floor conversion platforms. The bottom formwork, the two side formworks and the cross-sections of the two conversion platforms form a pouring chamber with an opening on the top. By installing the bottom formwork and the side formwork between the two conversion platforms, the height difference of the stairs is reduced, and the accumulation of concrete at the bottom of the stairs is reduced.

[0004] However, when using this method, the middle transfer platform needs to be cast first each time, and the stairs between the two adjacent transfer platforms can only be cast after the middle transfer platform solidifies. The operation is more troublesome and the efficiency is relatively low. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a gate grille device for pouring concrete on stairs, which can reduce the occurrence of concrete accumulation at the bottom of the stairs without the need to pour the transfer platform and the stairs separately. The operation is very simple and the work efficiency is greatly improved.

[0006] The second purpose of the present invention is to provide a method for pouring concrete on stairs, which can directly pour concrete on the stairs and also reduce the occurrence of concrete accumulation at the bottom of the stairs, thereby greatly improving the pouring efficiency.

[0007] One of the above-mentioned purposes of the present invention is achieved through the following technical scheme: a gate grille device for pouring concrete on stairs, comprising a mounting rod and an intercepting rod arranged on one side of the mounting rod, wherein the intercepting rod is perpendicular to the mounting rod and a plurality of intercepting rods are arranged at equal intervals along the length direction of the mounting rod.

[0008] By adopting the above technical solution, when the stairs to be poured have a certain height, the intercepting rod can be inserted into the pouring chamber by holding the installation rod. The intercepting rod can block the poured concrete and reduce the flow rate of the concrete. In addition, multiple intercepting rods can be installed at intervals according to the height of the stairs to gradually reduce the flow rate of the concrete. There is no need to cast the transfer platform and the stairs separately, which can reduce the accumulation of concrete at the bottom of the stairs. The operation is very simple and greatly improves work efficiency.

[0009] In a preferred example, the present invention may be further configured as follows: a handle is provided on the side wall of the mounting rod, and the handle is located on a side of the mounting rod away from the intercepting rod.

[0010] By adopting the above technical solution, when it is necessary to insert the intercepting rod into the casting chamber, the staff can directly hold the handle to carry out the installation work, which is more convenient to operate.

[0011] In a preferred example, the present invention can be further configured as follows: the mounting rod and the intercepting rod are detachably connected via a connecting assembly, the connecting assembly comprising a mounting hole provided on the side wall of the mounting rod and a limit block fixedly connected to one end of each of the intercepting rods, the intercepting rod slidingly cooperates with the mounting hole, a limit piece is provided on one side of the mounting rod, and the limit block is located between the mounting rod and the limit piece.

[0012] By adopting the above technical solution, when in use, the intercepting rod is directly inserted into the mounting hole, and then the limiting block can be fixed between the limiting member and the mounting rod through the limiting member, which makes disassembly and assembly very convenient.

[0013] In a preferred example, the present invention may be further configured as follows: a plurality of mounting holes are provided spaced apart along the length direction of the mounting rod.

[0014] By adopting the above technical solution, the staff can install the intercepting rod in the appropriate installation hole as needed, and the operation is more flexible.

[0015] In a preferred example, the present invention can be further configured as follows: a placement groove for accommodating the limit block is opened on one side of the installation rod, and the placement groove is communicated with one end of the installation hole.

[0016] By adopting the above technical solution, during installation, the end of the intercepting rod away from the limit block is inserted into the installation hole from the placement groove, and then the limit block can be placed in the placement groove. The tube fixes the position of the limit block in the placement groove through the limit piece, making the installation tighter.

[0017] In a preferred example, the present invention can be further configured as follows: the cross-section of the mounting rod is rectangular, the limiting member includes two clamping plates with U-shaped cross-sections which are sleeved on both ends of the mounting rod, the two clamping plates have openings facing each other, a connecting rod is fixed between the two clamping plates, and the connecting rod is located on the side of the mounting rod facing the limit block.

[0018] By adopting the above technical solution, after the intercepting rod is installed into the mounting hole, the two clamping plates are directly operated to slide from one side of the mounting rod to the mounting rod, and the connecting rod is located on the side of the mounting rod facing the limit block. The limit piece can be installed on the mounting rod, and the limit block can be clamped between the connecting rod and the mounting rod.

[0019] In a preferred example, the present invention may be further configured as follows: the handle is fixedly connected to a side of the connecting rod away from the clamping plate.

[0020] By adopting the above technical solution, when the limit member is installed on the mounting rod, the handle is also installed at the same time, which makes the installation simpler. At the same time, installing the handle after the intercepting rod does not affect the installation work of the intercepting rod.

[0021] In a preferred example, the present invention may be further configured as follows: a fixing bolt is threadedly connected to one side of the two clamping plates that are opposite to each other, and the fixing bolt is threadedly connected to the mounting rod.

[0022] By adopting the above technical solution, the fixing bolt can further fix the limiting member and the mounting rod, thereby preventing the limiting member from falling off the mounting rod under the action of external force.

[0023] The second objective of the present invention is achieved by the following technical solution: S1: erecting a support;

[0024] S2: Fix the bottom mold on the bracket;

[0025] S3: side molds are installed on both sides of the bottom mold, and a pouring chamber for concrete injection is formed between the bottom mold and the two side molds;

[0026] S4: Clean the debris in the bottom mold and side mold;

[0027] S5: The upper and lower steel meshes are fixed between the two side forms, and a gap of 2-4 cm is left between the lower steel mesh and the bottom form to form a steel protection layer.

[0028] S6: A baffle is fixed to the side of the two side molds away from the bottom mold, the baffle is located between the two side molds and the side away from the bottom mold is flush with the side of the side mold away from the bottom mold, and the height of two adjacent baffles is that the side of the upper baffle facing the bottom mold and the side of the lower baffle away from the bottom mold are on the same horizontal plane.

[0029] S7: passing the intercepting rod through the upper steel mesh and the lower steel mesh in sequence and making the end of the intercepting rod away from the mounting rod abut against the side of the bottom mold facing the baffle;

[0030] S8: injecting concrete from the upper part of the bottom form into the casting chamber through a concrete pump, and injecting concrete into the casting chamber from between the upper steel mesh and the lower steel mesh;

[0031] S9: After pouring is completed, the intercepting rod is pulled out;

[0032] S10: vibrating the poured concrete in the pouring chamber;

[0033] S11: After the concrete solidifies and takes shape, the bracket, bottom form, side form and baffle are removed to complete the concrete pouring work of the stairs.

[0034] By adopting the above technical solution, during pouring, a pouring chamber for pouring concrete can be formed by the bottom form, the side form and the baffle. When the concrete injected into the pouring chamber by the concrete pump flows downward along the bottom form, the intercepting rod can block the concrete and slow down the flow of the concrete, so that the speed of the concrete when it finally reaches the lower part of the stairs will not be too fast, thereby reducing the phenomenon of concrete accumulation at the lower part of the stairs.

[0035] In summary, the beneficial technical effects of the present invention are:

[0036] 1. The installation rod and the interception rod can block the concrete and reduce the flow rate of concrete. It is not necessary to cast the transfer platform and the stairs separately to reduce the accumulation of concrete at the bottom of the stairs. The operation is very simple and greatly improves the work efficiency.

[0037] 2. The mounting rod and the intercepting rod are detachably connected through a connecting assembly so that they can be reused and are very convenient to carry after use;

[0038] 3. The setting of the fixing bolt can make the connection between the limiter and the mounting rod more stable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0045] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0046] Embodiment 1:

[0047] Reference Figure 1 , is a gate grille device for pouring concrete on stairs disclosed in the present invention, comprising a mounting rod 1, an intercepting rod 2 vertically fixed to the side wall of the mounting rod 1, and a handle 3 fixed to the side wall of the mounting rod 1. A plurality of intercepting rods 2 are provided and are arranged at equal intervals along the length direction of the mounting rod 1, and the handle 3 is fixed to the side of the mounting rod 1 away from the intercepting rod 2. The cross section of the mounting rod 1 can be circular or rectangular, as long as it can connect multiple intercepting rods 2, and the shape of the mounting rod 1 is not limited here.

[0048] The implementation principle of this embodiment is: when in use, the staff directly holds the handle 3 to insert the interception rod 2 into the pouring chamber, and multiple interception rods can be installed at intervals according to the height of the stairs. The interception rod 2 can block the concrete and reduce the flow rate of the concrete, so that the concrete will not flow too fast when it flows to the lower part of the stairs, thereby reducing the phenomenon of concrete accumulation at the lower part of the stairs. In addition, due to the simple structure of the device, when in use, the staff can select steel bars of suitable sizes from the steel waste. Now it is welded and made, which is very simple to make, and it can also achieve the reuse of steel waste.

[0049] Embodiment 2:

[0050] Reference Figure 2 and Figure 3The difference between this embodiment and the first embodiment is that the mounting rod 1 and the intercepting rod 2 are detachably connected through a connecting assembly 4, the connecting assembly 4 includes a mounting hole 41 provided on the side wall of the mounting rod 1 and a stopper 42 fixedly connected to one end of each intercepting rod 2, a plurality of mounting holes 41 are provided at intervals along the length direction of the mounting rod 1, and a placement groove 43 for accommodating the stopper 42 is provided on the side wall of the mounting rod 1, the placement groove 43 is located at one end of the mounting hole 41 and communicated with each mounting hole 41. When the intercepting rod 2 and the mounting rod 1 need to be assembled, the end of the intercepting rod 2 away from the stopper 42 is directly inserted into the mounting hole 41 from the placement groove 43 until the stopper 42 is embedded in the placement groove 43. The mounting holes 41 are provided at intervals, and the staff can install the intercepting rod 2 into a suitable mounting hole 41 as needed, so as to adjust the distance between two adjacent intercepting rods 2. At the same time, in order to fix the position of the stopper 42 in the placement groove 43, a limiter 5 is provided on one side of the mounting rod 1 where the placement groove 43 is provided.

[0051] Reference Figure 3 The limiting member 5 includes a U-shaped clamping plate 51 clamped at both ends of the mounting rod 1 and a connecting rod 52 fixed between the two clamping plates 51. The connecting rod 52 is fixed to the side wall of the two clamping plates 51 close to the placement groove 43, and the handle 3 is fixed to the side of the connecting rod 52 away from the clamping plate 51. After the intercepting rod 2 is installed in the mounting hole 41 and the limiting block 42 is embedded in the placement groove 43, the two clamping plates 51 are directly slid from one side of the mounting rod 1 to the two ends of the mounting rod 1, and the connecting rod 52 is located on the side of the mounting rod 1 where the placement groove 43 is opened. At this time, the mounting rod 1 is clamped in the cavity formed by the two clamping plates 51 and the connecting rod 52.

[0052] At the same time, in order to prevent the limiting member 5 from sliding off the mounting rod 1 under the action of external force, a fixing bolt 53 is threadedly connected on the back side of the two clamping plates 51, and the fixing bolt 53 is threadedly connected to the mounting rod 1. The fixing bolt 53 can fix the limiting member 5 and the mounting rod 1 more firmly.

[0053] The implementation principle of this embodiment is: when in use, directly insert the end of the intercepting rod 2 away from the limiting block 42 into the mounting hole 41 from the side of the mounting rod 1 where the placement groove 43 is opened, so that the limiting block 42 is finally placed in the placement groove 43, and then operate the limiting member 5 to make the two clamping plates 51 slide from one side of the mounting rod 1 to the two ends of the mounting rod 1, and then connect the clamping plates 51 and the mounting rod 1 together through the fixing bolts 53. The staff can directly operate the handle 3 to insert the intercepting rod 2 into the casting chamber. The detachable connection between the mounting rod 1 and the intercepting rod 2 allows the gate grille to be reused and can be directly removed when not in use, which is very convenient for transportation.

[0054] Embodiment three:

[0055] Reference Figure 4 and Figure 5 , is a method for pouring concrete for stairs disclosed in the present invention, which comprises the following steps:

[0056] S1: Setting up a support 61 according to the size and shape of the stairs to be cast;

[0057] S2: Fixing the bottom mold 62 on the bracket 61;

[0058] S3: Fixing side molds 63 on both sides of the bottom mold 62, the side molds 63 are located on the side of the bottom mold 62 away from the bracket 61, and a casting chamber for concrete injection is formed between the bottom mold 62 and the two side molds 63;

[0059] S4: Clean the debris in the bottom mold 62 and the side mold 63 to ensure the working surface is clean;

[0060] S5: Two layers of steel mesh are fixed between the two side molds 63, which are respectively called upper steel mesh 64 and lower steel mesh 65, and a gap of 2-4 cm is left between the lower steel mesh 65 and the bottom mold 62 to form a steel protection layer.

[0061] S6: A baffle plate 66 is fixedly connected between the two side molds 63, and the side of the baffle plate 66 away from the bottom mold 62 is flush with the side of the side mold 63 away from the bottom mold 62, and the side of the upper baffle plate 66 of the two adjacent baffle plates 66 facing the bottom mold 62 is on the same horizontal plane as the side of the lower baffle plate 66 away from the bottom mold 62.

[0062] S7: Holding the handle 3, the interception rod 2 is passed through the upper steel mesh 64 and the lower steel mesh 65 in sequence, and the end of the interception rod 2 away from the installation rod 1 is abutted against the side of the bottom mold 62 facing the baffle 66. Here, multiple interception rods 2 can be inserted at intervals along the length direction of the staircase according to the length of the staircase;

[0063] S8: injecting concrete from the upper part of the bottom mold 62 into the casting chamber through a concrete pump, and injecting concrete into the casting chamber from between the upper steel mesh 64 and the lower steel mesh 65;

[0064] S9: After pouring is completed, the handle 3 is held to pull out the intercepting rod 2;

[0065] S10: vibrating the poured concrete in the pouring chamber;

[0066] S11: After the concrete is solidified, the support 61, the bottom form 62, the side form 63 and the baffle 66 are removed.

[0067] It is understandable that when the interception rod 2 is pulled out, the interception rod 2 at the corresponding position can be pulled out according to the pouring speed. When the pouring chamber under one interception rod 2 is poured, the corresponding interception rod 2 can be pulled out. Of course, when the staircase to be poured is relatively wide, the staff can also insert multiple interception rods 2 in parallel, so that multiple interception rods 2 can play a role in blocking the concrete.

[0068] Preferably, the intercepting rod 2 is inserted at the intersection of the inclined part of the bottom mold 62 and the plane of the conversion platform.

[0069] The implementation principle of the present invention is that the concrete delivered to the pouring chamber by the pump flows downward along the bottom mold 62. When it flows to the interception bar 2, the cross-sectional area for the concrete flow is reduced due to the obstruction of the interception bar 2, so the concrete flow rate is reduced. When the concrete flows out from the interception bar 2, the flow rate will not increase significantly due to reaching the horizontal conversion platform, thereby playing the effect of slowing down the concrete flow rate. After multiple obstructions by the interception bar 2, the concrete finally reaches the lower part of the stairs at a relatively uniform speed, reducing the phenomenon of concrete accumulation.

[0070] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
