Description

Technical Field

[0001] The utility model relates to the field of engineering construction, in particular to a steel bar bracket. Background Art

[0002] As the construction industry becomes increasingly sophisticated in its management, the demand for civilized on-site construction is growing. As a key management area within the entire construction site, the rebar yard, with its rational arrangement of raw rebar materials, has become a key focus of on-site civilized construction management. Currently, the commonly used rebar supports on construction sites are essentially constructed by connecting horizontal and vertical I-beams, with all rebar stacked atop the horizontal I-beams.

[0003] There are several problems with this type of steel support:

[0004] 1. There are many types of steel bars on site, with as many as 9 types ranging from HRB400-12 to HRB400-32. These types of steel bars are mixed together, which is inconvenient for steel workers to use. Especially for the steel bars at the bottom layer, they need to lift the upper layers of steel bars away before they can be used, which is time-consuming and labor-intensive.

[0005] 2. Each bundle of steel bars is pressed tightly together, and there is no gap at the bottom of the steel bars piled up above, which means that it is impossible to directly wear wire rope to lift the steel bars. Each time the steel bars are lifted, one end of the bundle of steel bars must be lifted first to leave a gap at the bottom of the steel bars, and then the wire rope must be passed through the bottom of both ends of the steel bars to lift the steel bars. When one end of the steel bar is lifted and the wire rope is worn, it is difficult to hook the bar, and the end of the steel bar is not firmly hung. The steel bar is easily unhooked and falls, hitting the workers, posing a safety hazard. On the other hand, wearing the wire rope is time-consuming, labor-intensive and inconvenient.

[0006] 3. All the steel bars are piled up together, making it inconvenient to take inventory of the number of remaining steel bars on site every month, especially for steel bars of similar models with small size differences, which are even more difficult to distinguish during inventory.

[0007] 4. All the steel bars are piled together and stacked in a disorderly manner. The overall civilized construction is poor and the image of the steel bar yard is not good. Utility Model Content

[0008] The purpose of the utility model is to solve the problems of chaotic steel bar stacking, inconvenience in inventory checking, hoisting and the like in the prior art, and to propose a steel bar bracket.

[0009] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0010] A steel bar support, comprising a plurality of prefabricated reinforced concrete components, and longitudinal steel sections, bottom-layer transverse steel sections, middle-layer transverse steel sections, and upper-layer transverse steel sections connecting two adjacent prefabricated reinforced concrete components;

[0011] A precast reinforced concrete component is connected to other precast reinforced concrete components adjacent to it laterally or longitudinally through longitudinal steel sections and bottom transverse steel sections, and the longitudinal steel sections and bottom transverse steel sections are connected to the lower part of the precast reinforced concrete component;

[0012] The precast reinforced concrete components are provided with a middle trough frame for accommodating the ends of the middle transverse steel sections and an upper trough frame for accommodating the ends of the upper transverse steel sections. The middle trough frame and the upper trough frame are trough structures with upper openings. The middle trough frame is deeper than the upper trough frame, and the middle trough frame and the upper trough frame are respectively provided with built-in baffles.

[0013] The middle-layer transverse steel and the upper-layer transverse steel are both located above the bottom-layer transverse steel and are parallel to it;

[0014] The space between the bottom transverse steel section and the middle transverse steel section, the space between the middle transverse steel section and the upper transverse steel section, and the space above the upper transverse steel section are all areas for placing bundled steel bars.

[0015] As a further preferred solution, connectors are respectively provided around the bottom of the prefabricated reinforced concrete component, and the ends of the longitudinal steel sections and the bottom transverse steel sections are fixed to the connectors.

[0016] As a further preferred solution, the connecting member is a T-shaped steel plate, and the two plates of the T-shaped steel plate are respectively provided with bolt holes for installation at the lower position of the prefabricated reinforced concrete component and the end of the longitudinal steel or the bottom transverse steel.

[0017] As a further preferred solution, the prefabricated reinforced concrete component is a quadrangular pyramid structure.

[0018] As a further preferred solution, the length direction of the prefabricated reinforced concrete member is parallel to the direction of the longitudinal steel section;

[0019] The width of the upper surface of the precast reinforced concrete component is a = 30 cm;

[0020] The length of the upper surface is composed of the length d from the edge of one side of the length to the edge of the middle trough frame, the length d from the edge of the middle trough frame to the edge of the upper trough frame, the length d from the edge of the upper trough frame to the edge of the other side of the length, and the width e of the middle trough frame and the width e of the upper trough frame. That is, the length of the upper surface is 3d+2e=40cm, where d=10cm and e=5cm;

[0021] The upper trough depth is h1 = 33 cm, the middle trough depth is h2 = 66 cm, and the height of the prefabricated reinforced concrete component is h3 = 100 cm;

[0022] The width of the lower surface of the prefabricated reinforced concrete component is b=50cm, the length is c=60cm, and the inclined heights of the four faces of the tetrahedral structure are all H=√10100 cm.

[0023] As a further preferred solution, the longitudinal steel, the bottom transverse steel, the middle transverse steel and the upper transverse steel are all I-shaped steel.

[0024] As a further preferred solution, the ratio of the spacing between the precast reinforced concrete components and the transversely adjacent precast reinforced concrete components to the spacing between the precast reinforced concrete components and the longitudinally adjacent precast reinforced concrete components is (0.27-0.75). Beneficial effects

[0025] 1. All steel bars are stacked neatly and orderly, the on-site image is more standardized, and standardized management of the steel bar yard is achieved.

[0026] 2. The amount of remaining steel bars on the steel support is clear at a glance, making inventory more convenient.

[0027] 3. The steel bar hook makes lifting more convenient and reduces safety hazards.

[0028] 4. It is convenient to take out steel bars. Each layer of steel bars can be directly extracted and used. Even if there are steel bars stacked on the two upper layers, the bottom layer of steel bars can be directly pulled out from both ends and used. Unlike in the past, if the bottom layer of steel bars needs to be used, the upper layer of steel bars must be removed, which reduces the workload. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] The core of this technical solution is to design a new type of steel bar stacking bracket, on which all steel bars are stacked in layers to ensure that the steel bars are stacked neatly and the lifting is safe and convenient.

[0035] like Figure 1As shown, a steel bar support of the present invention includes multiple prefabricated reinforced concrete components 1, and longitudinal steel sections 2, bottom transverse steel sections 31, middle transverse steel sections 32, and upper transverse steel sections 33 connecting two adjacent prefabricated reinforced concrete components 1.

[0036] A precast reinforced concrete component 1 is connected to other precast reinforced concrete components 1 adjacent thereto laterally or longitudinally via longitudinal steel sections 2 and bottom transverse steel sections 31 , which are connected to the lower portion of the precast reinforced concrete component 1 .

[0037] The precast reinforced concrete member 1 is provided with a middle channel frame 34 for accommodating the end of the middle transverse steel 32 and an upper channel frame 35 for accommodating the end of the upper transverse steel 33. The middle channel frame 34 and the upper channel frame 35 are slot structures with upper openings. The middle channel frame 34 is deeper than the upper channel frame 35. The middle channel frame 34 and the upper channel frame 35 are respectively built with baffles 36.

[0038] The middle transverse steel 32 and the upper transverse steel 33 are both located above the bottom transverse steel 31 and are parallel thereto;

[0039] The space between the bottom transverse steel section 31 and the middle transverse steel section 32, the space between the middle transverse steel section 32 and the upper transverse steel section 33, and the space above the upper transverse steel section 33 are all areas for placing bundled steel bars.

[0040] The longitudinal steel sections 2, bottom-layer transverse steel sections 31, middle-layer transverse steel sections 32, and upper-layer transverse steel sections 33 are all I-beams, using thickened No. 8 I-beams (specified at 80*50*8mm). Three transverse steel sections are laid between every two precast reinforced concrete components 1, and the I-beams connecting the precast reinforced concrete components 1 longitudinally are longitudinal steel sections 2. Therefore, a complete set of steel support brackets is composed of several precast reinforced concrete components 1, overlapped by transverse and longitudinal I-beams, forming a frame structure. The number of precast reinforced concrete components 1 and the number of I-beams depends on the size of the on-site reinforcement site.

[0041] The assembly process of the entire set of steel support is as follows: the horizontal distance between the bottom ends of each prefabricated reinforced concrete component 1 is set to 1 meter, and the longitudinal distance between each prefabricated reinforced concrete component 1 is set to 2.67 meters. A pre-buried T-shaped steel plate with two holes is fixed longitudinally at the middle position of the bottom of each prefabricated reinforced concrete component 1 in four directions, such as Figure 2 As shown, holes of the same size as the embedded steel plates are punched at both ends of the bottom transverse steel 31 and the longitudinal steel 2. The bottom transverse steel 31 and the longitudinal steel 2 are then connected to the embedded T-shaped steel plates on the bottom of the prefabricated reinforced concrete member 1 by bolts, so that the entire set of steel support brackets is fixed.

[0042] After the bottom layer of transverse steel sections 31 and longitudinal steel sections 2 are secured, the steel bars can be laid on top of the transverse steel sections 31. The middle layer of transverse steel sections 32 is then laid and horizontally installed in the middle layer of channel frames 34 on the same level between the two transverse precast reinforced concrete components 1. Similarly, the upper layer of transverse steel sections 33 is finally laid and horizontally installed in the upper layer of channel frames 35 on the same level between the two transverse precast reinforced concrete components 1. The middle layer of channel frames 34 is deeper than the upper layer of channel frames 35 and therefore lower in height than the upper layer of channel frames 35.

[0043] A small reinforced concrete baffle 36 is set in the middle position of the middle trough frame 34 and the upper trough frame 35 to clamp the middle transverse steel 32 and the upper transverse steel 33 to prevent the I-beam from being displaced under the pressure during the storage and retrieval of the steel bars. The length of the middle transverse steel 32 and the upper transverse steel 33 is set according to the horizontal distance between the baffles 36 of the corresponding trough frames in the two prefabricated reinforced concrete components 1. In this way, when the transverse I-beam is horizontally mounted on the notches of the two prefabricated reinforced concrete components, the position of the transverse I-beam is fixed due to the action of the middle baffle 36 of the notch, thereby preventing the horizontal displacement of the transverse I-beam.

[0044] like Figure 3 and 4 As shown, the prefabricated reinforced concrete component 1 is a tetrahedral structure with an upper surface width of a=30cm and a length of 3d+2e=40cm. As shown in the figure, the part d=10cm is opened in the middle of the trapezoidal body of the tetrahedral pyramid. The shallower groove has a width of e=5cm and a depth of h1=33cm. The deeper groove has a width of e=5cm and a depth of h2=66cm. The height between the upper and lower surfaces of the entire tetrahedral pyramid is h3=100cm. The width of the lower surface of the tetrahedral pyramid is b=50cm and the length is c=60cm. The inclined heights of the four faces of the tetrahedral pyramid are all H=√10100 cm.

[0045] Assume that the construction site receives 10 pieces of HRB400E-12 rebars, 9 pieces of HRB400E-14 rebars, 10 pieces of HRB400E-16 rebars, 6 pieces of HRB400E-18 rebars, 8 pieces of HRB400E-20 rebars, 5 pieces of HRB400E-22 rebars, and 5 pieces of HRB400E-25 rebars, a total of 7 types and specifications of rebars, totaling approximately 106 tons, which need to be unloaded and stacked.

[0046] First, assemble the steel support. Based on the number of steel bars, the precast reinforced concrete components 1 are set to 7 columns and 4 rows. The horizontal distance between the bottom layer of any two precast reinforced concrete components 1 is 1 meter, and the longitudinal spacing between the precast reinforced concrete components 1 is 2.67 meters. Any two precast reinforced concrete components 1 are connected to each other through the bottom layer of transverse I-beams and longitudinal I-beams. After the transverse I-beams and longitudinal I-beams are fixed to the precast reinforced concrete components with bolts, the entire steel support is fixed. Each transverse I-beam can lay 3 bundles of steel bars. Each column of transverse I-beams in this steel support has a total of three layers, which can store 3 layers * 3 bundles * 2 tons = 18 tons of steel bars. That is, this support can store a total of 18 * 6 = 108 tons of steel bars.

[0047] Each type of steel bar should be stacked on the same row of horizontal I-beams as much as possible for easy access. For example, HRB400E-12 steel bars can be stacked in the leftmost row of the steel bar support. There are three layers in total, and each layer can hold three bundles of steel bars. That is, nine bundles of HRB400E-12 steel bars can be stacked in the leftmost row, and another bundle can be stacked in the nearby row. This row can be stacked on the same row of beams with eight pieces of HRB400E-20 steel bars, and so on.

[0048] Once stacked, they can be directly hoisted with wire ropes when needed on-site. (Previously, hoisting rebar brackets was difficult because each piece of rebar was piled together, leaving no gaps between the rebar surfaces and making it impossible to lift with wire ropes.) If the first layer of rebar remains unused and a different type of rebar is needed from the next layer, the next layer can be directly pulled out from both ends. This eliminates the previous problem of having to remove the upper layer of rebar before using the lower layer of rebar, saving time and effort.

[0049] It can be seen that the utility model solves the current problems of chaotic stacking of steel bars, inconvenient inventory and lifting, etc. as a whole, making the lifting of steel bars safer and simpler, taking steel bars more convenient, making the inventory of the number of steel bars more convenient and clear at a glance, making the steel bars neatly stacked, and improving the image of civilized construction on site.

[0050] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
