Description

Technical Field

[0001] The invention relates to a prefabricated floor slab steel bar mould, in particular to a steel mesh binding tool. Background Art

[0002] After the mold of the prefabricated composite floor reinforcement is installed, the reinforcement needs to be laid and tied, and the next process can be carried out after the tying is completed. The prior art reinforcement laying and tying processes need to be completed on the assembly line, and the requirements for the reinforcement tying are as follows: full tying on all sides, and plum blossom tying in the middle, that is, tying every other one. For each tying point, the wire needs to be wrapped at least four times and cannot be broken. Since there are many tying points for a single floor slab and the tying time is too long, the production rhythm of the assembly line is seriously affected, causing congestion on the production line and delaying the output of the assembly line. In addition, due to different projects and different apartment types between projects, the sizes of the floor slabs in each apartment type are different, resulting in different sizes of starting bars for the floor slabs. The existing molds cannot meet the production of floor slabs with different sizes of starting bars. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a steel mesh binding tool to address the deficiencies in the prior art. The steel mesh binding tool can realize offline binding of steel mesh, reduce the operating hours of bottleneck joints in the assembly line, and can locate the distance between the first steel bar and the outer edge, thereby meeting the production of floor slabs with different starting bar sizes, thereby greatly improving the production efficiency of the assembly line.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A steel mesh binding tool comprises a rib, wherein the rib comprises a first rib, a second rib, a third rib and a fourth rib, the first rib and the second rib are arranged at a relative interval, the third rib and the fourth rib are arranged at a relative interval, the first rib, the second rib, the third rib and the fourth rib are enclosed to form a prefabricated area, and its structural characteristics are that a plurality of notches are provided on the first rib, the second rib, the third rib and the fourth rib, the first rib comprises a first standard part and a first compensating part, the second rib comprises a second standard part and a second compensating part, the first compensating part and the second compensating part are both arranged close to the fourth rib, the distance between the notch on the first compensating part closest to the fourth rib and the fourth rib is equal to the starting rib size, and the distance between the notch on the second compensating part closest to the fourth rib and the fourth rib is also equal to the starting rib size.

[0006] The second side guard is fixed on the trolley surface, and the other three side guards are arranged according to the corresponding position requirements. The four side guards are used to limit the steel bars. The four side guards enclose a prefabricated area. The notches on the side guards are conducive to the arrangement of the steel bars to ensure the horizontal and vertical distribution of the steel bars. The spacing between the notches is designed according to the requirements of the steel bar arrangement to ensure that the spacing between the steel bars meets the process requirements and design requirements. The main function of the first compensation part and the second compensation part is to locate the size of the first steel bar of the floor slab from the outer edge (that is, the starting bar size), and the distance between the notch closest to the fourth side guard and the fourth side guard is limited to the starting bar size. Therefore, by selecting different first compensation parts and second compensation parts, the production of floor slabs with different starting bar sizes can be met. When binding, the first compensation parts and second compensation parts that meet the project requirements can be selected for connection according to actual needs.

[0007] Further, the first standard part is composed of one standard part or at least two standard parts spliced ​​in sequence, and the first compensating part is composed of one compensating part or at least two compensating parts spliced ​​in sequence. When the first compensating part is spliced ​​in sequence by at least two compensating parts, the distance between the notch closest to the fourth rib on the compensating part closest to the fourth rib and the fourth rib is equal to the starting rib size. The second standard part is composed of one standard part or at least two standard parts spliced ​​in sequence, and the second compensating part is composed of one compensating part or at least two compensating parts spliced ​​in sequence. When the second compensating part is spliced ​​in sequence by at least two compensating parts, the distance between the notch closest to the fourth rib on the compensating part closest to the fourth rib and the fourth rib is equal to the starting rib size. The standard parts and compensating parts are used to form the tooling, and a certain number of standard parts and compensating parts are selected for use according to the needs and process requirements of different projects, and the required length is combined according to the actual situation, which greatly improves the versatility of the tooling.

[0008] Furthermore, each adjacent two standard parts, or two compensating parts, or one standard part and one compensating part are connected by bolts, or by snap-fitting, or by mortise and tenon, or by bonding.

[0009] Furthermore, the tooling also includes a protruding rib positioning plate and a limiting member, the protruding rib positioning plate is located outside the prefabricated area, and the protruding rib positioning plate is connected to the retaining edge through the limiting member.

[0010] During the binding process, it is necessary to determine the protruding length of the floor slab reinforcement and ensure that the protruding length is within the design allowable error range. Two protruding reinforcement positioning plates are placed outside the prefabricated area formed by the four retaining edges. The distance between the protruding reinforcement positioning plates and the relatively set retaining edges is ensured by limiting the distance between the protruding reinforcement positioning plates and the relatively set retaining edges, so that the distance between the protruding reinforcement positioning plates and the relatively set retaining edges meets the process requirements of the protruding reinforcement of the floor slab.

[0011] Furthermore, the protruding rib positioning plate includes a first positioning plate and a second positioning plate, the first positioning plate is relatively spaced apart from the first rib or the second rib, and the second positioning plate is relatively spaced apart from the third rib or the fourth rib.

[0012] Furthermore, the limiting member is provided with a limiting groove, and there are a plurality of limiting grooves, and the limiting grooves are connected with the retaining edge and / or the protruding rib positioning plate. Preferably, the limiting groove is abutted or clamped with the retaining edge and the protruding rib positioning plate, and the distance between the protruding rib positioning plate and the relatively arranged retaining edge is limited by the distance between the two limiting grooves. Generally, the protruding length of the floor slab reinforcement varies less, and a limiting member that meets the length dimension requirements can be designed according to the project characteristics.

[0013] Furthermore, the protruding rib positioning plate is an angle steel.

[0014] Furthermore, the distance between two adjacent slots in the plurality of slots is equal. The slot spacing can be designed according to the steel bar spacing required by the project to meet the steel bar spacing requirements.

[0015] Furthermore, the notch is a Y-shaped notch or a U-shaped notch, which is conducive to the fixation of the steel bars. The spacing between each two adjacent notches is preferably 150 mm, and 150 mm is the steel bar spacing requirement for most existing projects.

[0016] Furthermore, the tooling also includes a filling piece, which is arranged in the prefabricated area. The filling piece serves as a protective layer between the steel bars and the trolley surface, and mainly supports the steel bars to prevent the steel bars from bending and sinking under their own gravity, thereby causing insufficient extension length of the steel bars and insufficient thickness of the concrete protective layer. The filling piece is preferably a wooden board or a foam board.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1) The steel mesh binding tool of the present invention uses a compensating piece to locate the distance between the first steel bar of the floor slab and the outer edge (i.e., the starting bar size), and a compensating piece that meets the conditions can be designed according to project requirements. This overcomes the problem of different starting bar sizes of the floor slab due to different projects, different apartment types between projects, and different floor slab sizes in different apartment types. When binding, according to actual needs, compensating pieces that meet the project requirements are selected for connection, which can meet the production of floor slabs with different starting bar sizes.

[0019] 2) The first and second side guards of the present invention are formed by sequentially splicing standard parts and compensating parts. According to the needs and process requirements of different projects, a certain number of standard parts and compensating parts are selected for use in combination, and different lengths can be combined according to actual conditions, which greatly improves the versatility of the tooling.

[0020] 3) The steel mesh binding tool of the present invention can realize the off-line binding of the floor mesh, ensure the distribution of the steel bars in the floor mesh, reduce the operating hours of the bottleneck joints of the assembly line, and improve the production efficiency of the assembly line.

[0021] 4) The floor mesh is tied in advance under the assembly line and placed in the designated position according to the order of leaving the kiln. During actual production, the floor mesh is taken out according to the component number and placed in the corresponding tooling to shorten the online binding time of the floor and improve the production efficiency of the assembly line.

[0022] 5) Through experiments, it was found that the floor mesh binding time was 26 minutes using the original operation method. By using the steel mesh binding tool of the present invention and the method of binding under the assembly line, it only takes 10 minutes to complete the assembly of the floor mesh, which greatly improves the work efficiency on the assembly line. The per capita production efficiency increased from the original 1.26 to 2.1, an increase of 66.7%, which greatly promoted the improvement of the production efficiency of the assembly line.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0035] The present invention provides a steel mesh binding tool, such as Figure 1 , Figure 2 As shown, it includes a rib, and the rib includes a first rib 11, a second rib 12, a third rib 13 and a fourth rib 14. The first rib 11 and the second rib 12 are arranged at a relative interval, and the third rib 13 and the fourth rib 14 are arranged at a relative interval. The first rib 11, the second rib 12, the third rib 13 and the fourth rib 14 are enclosed to form a prefabricated area. Its structural characteristics are that a plurality of notches 6 are opened on the first rib 11, the second rib 12, the third rib 13 and the fourth rib 14, the first rib 11 includes a first standard part and a first compensating part, the second rib 12 includes a second standard part and a second compensating part, the first compensating part and the second compensating part are both arranged close to the fourth rib 14, the distance between the notch 6 on the first compensating part closest to the fourth rib 14 and the fourth rib 14 is equal to the starting rib size, and the distance between the notch 6 on the second compensating part closest to the fourth rib 14 and the fourth rib 14 is also equal to the starting rib size.

[0036] The tooling also includes a protruding rib positioning plate, which is preferably an angle steel. The protruding rib positioning plate is located outside the prefabricated area, and the protruding rib positioning plate is connected to the sidewall through the stopper 3. The protruding rib positioning plate includes a first positioning plate 21 and a second positioning plate 22, wherein the first positioning plate 21 is arranged relative to the first sidewall 11 or the second sidewall 12, and the second positioning plate 22 is arranged relative to the third sidewall 13 or the fourth sidewall 14.

[0037] Preferably, the first standard part is composed of one standard part 4 or at least two standard parts 4 are spliced ​​in sequence, and the first compensating part is composed of one compensating part 5 or at least two compensating parts 5 are spliced ​​in sequence. When the first compensating part is spliced ​​in sequence by at least two compensating parts 5, the distance between the notch closest to the fourth rib 14 on the compensating part 5 closest to the fourth rib 14 and the fourth rib 14 is equal to the starting rib size; the second standard part is composed of one standard part 4 or at least two standard parts 4 are spliced ​​in sequence, and the second compensating part is composed of one compensating part 5 or at least two compensating parts 5 are spliced ​​in sequence. When the second compensating part is spliced ​​in sequence by at least two compensating parts 5, the distance between the notch closest to the fourth rib 14 on the compensating part 5 closest to the fourth rib 14 and the fourth rib 14 is equal to the starting rib size.

[0038] The second side guard is fixed on the trolley surface, and the other three side guards are arranged according to the corresponding position requirements. Among them, the four side guards are used to limit the steel bars. The notches on the side guards are conducive to the arrangement of the steel bars to ensure the horizontal and vertical distribution of the steel bars. The spacing between the notches is designed according to the requirements of the steel bar arrangement to ensure that the spacing of the steel bars meets the process requirements and design requirements. Two protruding rib positioning plates are placed outside the prefabricated area formed by the four side guards. The distance between the protruding rib positioning plates and the relatively arranged side guards meets the process requirements for the protruding ribs of the floor slab. The distance between the notch closest to the fourth side guard on the first and second compensation parts and the fourth side guard is used to limit the size of the starting ribs. The first and second compensation parts that meet the requirements can be selected according to the requirements of the starting rib size for connection.

[0039] During the binding process, it is necessary to determine the length of the floor slab reinforcement extending out of the frame structure and ensure that the extended length is within the design allowable error range, and to use the limiter to ensure the distance between the extended reinforcement positioning plate and the relatively set retaining edge. At this point, the assembly work of the steel mesh binding tool has been completed, and offline binding can be carried out normally.

[0040] Preferably, every two adjacent standard parts 4, or two compensating parts 5, or one standard part 4 and one compensating part 5 are connected by bolts, or by snap-fitting, or by mortise and tenon, or by bonding. Figure 5An embodiment of a bolt connection is shown, Figure 7 An embodiment of a mortise and tenon connection is shown.

[0041] Combination Figure 4 There are multiple notches 6 on the plate edge of the standard part 4, and the distance between two adjacent notches 6 in the multiple notches 6 is equal. The notch spacing can be designed according to the steel bar spacing required by the project to meet the requirements of the steel bar spacing. The spacing between each two adjacent notches 6 is 150mm, and the notches 6 are Y-shaped notches or U-shaped notches. In actual use, the required length can be combined according to project requirements.

[0042] Furthermore, the limiting member 3 is provided with a limiting groove, and there are a plurality of limiting grooves, and the limiting grooves are cooperatively connected with the retaining edge and the protruding rib positioning plate. Preferably, the limiting groove is abutted or clamped with the retaining edge and the protruding rib positioning plate, and the distance between the protruding rib positioning plate and the relatively arranged retaining edge is limited by the distance between the two limiting grooves. A limiting member that meets the requirements can be designed according to the characteristics of the project. Generally, the protruding length of the floor slab steel bars varies less, and this solution can meet the needs of offline binding. In actual operation, a limiting member that meets the conditions can be selected according to the project requirements.

[0043] Preferably, the tooling further comprises a filling piece 7, which is arranged in the prefabricated area and is preferably a wooden board or a foam board. The filling piece mainly supports the steel bars to prevent the steel bars from bending and sinking under their own gravity, thereby causing insufficient extension length of the steel bars and insufficient thickness of the concrete cover.

[0044] by Figure 3 Taking the figure as an example, the actual selection of the steel mesh binding tool of the present invention is further explained:

[0045] The third flange 13 and the fourth flange 14 can be assembled by several standard parts as the full-length flange. For the first flange 11 and the second flange 12, it is only necessary to select standard parts and compensation parts of appropriate quantity and size for assembly to the target size.

[0046] Due to the diversity of floor slab sizes, the sizes of floor slab tooling (molds) are also diverse, so the first side 11 and the second side 12 are composed of standard parts + compensation parts. The length of a single standard part is 1.5m, and the length of the compensation part is between 0.1m and 1.5m. The compensation part takes 0.1m as a unit, and the sizes of common compensation parts are 0.1m, 0.2m, 0.3m, 0.4m, 0.5m and other five specifications. Standard parts and standard parts, standard parts and compensation parts, and compensation parts and compensation parts can be connected by bolts, or by snap-on connections, or by mortise and tenon connections, or by adhesive connections. Standard parts are not limited to Figure 5The bolt connection method shown is not limited to the compensation parts. Figure 7 The mortise and tenon connection method shown.

[0047] For the combination of standard parts and compensation parts:

[0048] If the length of the rib is 3.6m, the connection combination of standard parts + compensation parts is: 1.5m+1.5m+0.5m+0.1m;

[0049] If the length of the rib is 3.7m, the connection combination of standard parts + compensation parts is: 1.5m+1.5m+0.5m+0.2m;

[0050] If the length of the rib is 3.8m, the connection combination of standard parts + compensation parts is: 1.5m+1.5m+0.5m+0.3m;

[0051] If the length of the rib is 3.9m, the connection combination of standard parts + compensation parts is: 1.5m+1.5m+0.5m+0.4m;

[0052] If the length of the rib is 4.0m, the connection combination of standard parts + compensation parts is: 1.5m+1.5m+0.5m+0.5m;

[0053] If there are ribs with lengths of 3.65m, 3.68m, etc., consider increasing the types of compensation parts. Statistics show that the types of compensation parts for the floor slabs of various projects can generally be controlled within 10 types, so this assembly plan is feasible.

[0054] The improved technical solution can realize the offline binding of floor mesh, ensure the distribution of steel bars in the floor mesh, reduce the operating hours of bottleneck joints of the assembly line, and improve the production efficiency of the assembly line.

[0055] According to calculations, the per capita output is 1.26m 3 / person / 8h, increased to 2.1m 3 / person / 8h, lifting 0.84m 3 / person / 8h, the improvement is 66.7%. The annual benefit is about: 0.84*20*300*2500=12.6 million yuan. Note: 0.84 is the efficiency improvement value, 20 is the number of people on the production line, 300 is the annual working days, and 2500 is the average sales price of the floor. The formula means: the increase in production efficiency brings about an increase in output, thereby creating more value.

[0056] The steel mesh binding tool of the present invention uses a compensating piece to locate the distance between the first steel bar of the floor slab and the outer edge (i.e., the starting bar size), and a compensating piece that meets the conditions can be designed according to project requirements. This overcomes the problem that the starting bar sizes of the floor slabs are different due to different projects, different apartment types between projects, and different floor slab sizes in different apartment types. When binding, the compensating piece that meets the project requirements is selected for connection according to actual needs, so that the production of floor slabs with different starting bar sizes can be met.

[0057] The steel mesh binding tool of the present invention can realize the off-line binding of floor meshes. The floor meshes are bound in advance under the assembly line and placed in designated positions according to the kiln order. During actual production, the floor meshes are taken out according to the component numbers and placed in the corresponding tooling to shorten the online binding time of the floor, reduce the operating hours of the bottleneck joints of the assembly line, and improve the production efficiency of the assembly line.

[0058] The contents explained in the above embodiments should be understood as these embodiments are only used to more clearly illustrate the present invention, and are not used to limit the scope of the present invention.
