Description

Technical Field

[0001] The utility model relates to the field of construction engineering auxiliary equipment, in particular to a prefabricated beam and slab reinforcement positioning device. Background Art

[0002] The construction technology of prefabricated beams is becoming more and more mature. When prefabricating beams and slabs, it is necessary to use steel bars to tie them into a steel cage, and then lift the tied steel cage into the prepared formwork. After that, pouring is carried out to allow the steel cage to be immersed in the concrete to form the top plate of the beam and slab. When tying the steel cage, external auxiliary devices are needed to help workers tie it.

[0003] In the prior art, a patent with announcement number CN219132734U discloses a combined stand for binding reinforcement bars of prefabricated beam and slab top plates, which includes a base; it also includes two groups of support plates, two groups of support plates, a platform, a placement plate, an adjustment device and a moving device. The two groups of support plates are fixedly mounted on the left and right parts of the upper end of the base, the platform is mounted on the base through a moving device, the moving device is used to move the platform left and right, the placement plate is fixedly mounted on the upper end of the platform, the two groups of support plates are mounted on the adjustment device, the adjustment device is used to adjust the distance between the two groups of support plates, and multiple groups of positioning grooves are provided on the two groups of support plates.

[0004] In the above device, since the positioning grooves on the support plate are fixed, the spacing between the positioning grooves cannot be adjusted. At the same time, since some beam and slab steel bars have dense areas and non-dense areas, the longitudinal steel bar spacing in each area of ​​the same beam and slab along its length is different, that is, the longitudinal steel bar spacing in the dense area is smaller than the steel bar spacing in the non-dense area. The above device can only bind steel cages with fixed spacing, has high limitations in use, and poor versatility. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a prefabricated beam and slab steel bar positioning device, which solves the problem that the prefabricated beam and slab steel bar positioning device in the prior art can only bind steel bar cages with fixed spacing and has poor versatility.

[0006] According to an embodiment of the utility model, a prefabricated beam and slab reinforcement positioning device comprises a base and four groups of positioning mechanisms, two of which are fixedly arranged at both ends of the base along the width direction of the base for positioning the transverse reinforcements, and the other two groups of positioning mechanisms are slidably arranged at both ends of the base along the length direction of the base for positioning the longitudinal reinforcements, the positioning mechanism comprises an adjustment component and a plurality of positioning blocks arranged side by side, the positioning blocks are provided with positioning grooves, the adjustment component is connected to each of the positioning blocks for synchronously adjusting the spacing between the positioning blocks.

[0007] The technical principle of the utility model is:

[0008] The spacing between the four groups of positioning blocks is adjusted respectively through the adjustment components on the four positioning mechanisms, so that the spacing between the positioning blocks on the two positioning mechanisms arranged along the width direction of the base is the same as the spacing between the transverse reinforcements of the precast beam and slab, and the spacing between the positioning blocks on the two positioning mechanisms arranged along the length direction of the base is the same as the spacing between the longitudinal reinforcements of the precast beam and slab. Then, the transverse reinforcements and the longitudinal reinforcements are placed in the positioning grooves respectively, and the intersection of the transverse reinforcements and the longitudinal reinforcements is tied tightly with iron wire. After completing the longitudinal reinforcement binding of a section of the area, the two positioning mechanisms arranged along the length direction of the base can be slid, and their positions can be changed and then the spacing between the positioning blocks therein can be adjusted to position and bind the next section of longitudinal reinforcement.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] By setting up four groups of positioning mechanisms, the transverse steel bars and the longitudinal steel bars can be positioned separately. By setting the adjustment components, the spacing between the positioning blocks in the positioning mechanisms can be synchronously adjusted to adapt to the binding requirements of different steel bar spacings, thereby improving the versatility of the device. At the same time, the two positioning mechanisms arranged along the length direction of the base are slidably connected to the base, which is convenient for segmented binding of the longitudinal steel bar encrypted areas and non-encrypted areas.

DETAILED DESCRIPTION

[0028] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 1 and Figure 2 As shown, a prefabricated beam and slab steel bar positioning device in the utility model comprises a base 1 and four groups of positioning mechanisms, two of which are fixedly arranged at both ends of the base 1 along the width direction of the base 1 for positioning the transverse steel bars, and the other two groups of positioning mechanisms are slidably arranged at both ends of the base 1 along the length direction of the base 1 for positioning the longitudinal steel bars, the positioning mechanism comprises an adjusting component and a plurality of positioning blocks 13 arranged side by side, the positioning blocks 13 are provided with positioning grooves 14, the adjusting component is connected to each of the positioning blocks 13 for synchronously adjusting the spacing between the positioning blocks 13.

[0030] Specifically, Figure 2 As shown, the adjustment assembly includes a lower support member 2, an upper support member 3 and a plurality of connecting plates 4, wherein the lower support member 2 is a channel steel, which is installed above the base 1, and a lifting component is fixedly arranged on the lower support member 2; the upper support member 3 is an angle steel, which is fixedly connected to the moving end of the lifting component; adjacent connecting plates 4 are rotatably connected by pins 5, wherein any pin 5 is fixedly connected to the upper support member 3 or the lower support member 2, and the remaining pins 5 are horizontally slidably connected to the upper support member 3 or the lower support member 2, and the positioning block 13 is fixedly connected to the pin 5 in the upper support member 3 or the lower support member 2. In this embodiment, in order to facilitate the installation of steel bars, the pin 5 in the upper support member 3 of the positioning block 13 is fixedly connected.

[0031] By adopting the above scheme, the upper support member 3 is driven to move vertically through the lifting component, which drives each connecting plate 4 to rotate around the pin shaft 5. Since the upper and lower ends of each connecting plate 4 are horizontally slidably connected to the upper support member 3 and the lower support member 2 respectively, the upper and lower ends of each connecting plate 4 are respectively maintained on the same horizontal line, the angles between each connecting plate 4 are the same, and the distances between adjacent pin shafts 5 are maintained the same, thereby realizing the equal spacing and synchronous adjustment of each positioning block 13.

[0032] like Figure 3 As shown, according to another embodiment of the utility model, guide grooves 6 are opened in the horizontal direction on the upper support member 3 and the lower support member 2, a positioning hole 7 is provided in the middle of the upper support member 3 or the lower support member 2, the number of connecting plates 4 is an even number, the pin shaft 5 between the two connecting plates 4 of the middle member is installed in the positioning hole 7, and the pin shafts 5 at both ends of the remaining connecting plates 4 are respectively located in the guide grooves 6 of the upper support member 3 and the lower support member 2.

[0033] like Figure 3 As shown, according to another embodiment of the utility model, the lifting component includes a guide seat 10, a screw rod 9 and a moving block 11, wherein the guide seat 10 is fixedly installed on the lower support member 2 along the vertical direction; the screw rod 9 is vertically and rotatably arranged on the guide seat 10; the moving block 11 is threadedly connected to the screw rod 9 and is slidably connected to the guide seat 10, the upper support member 3 is fixedly connected to the moving block 11, and a handle 12 is provided at the end of the screw rod 9 away from the lower support member 2.

[0034] like Figure 1As shown, according to another embodiment of the utility model, two groups of electric slide rails 15 are arranged on the base 1, and the electric slide rails 15 are arranged parallel to the length direction of the base 1. Each electric slide rail 15 is provided with a slider 8, which is respectively connected to two groups of positioning mechanisms arranged along the length direction of the bottom plate. Since the steel bar arrangement of the beam plate is generally provided with a densified area and a non-densified area, when the steel bars are tied, they can be tied in sections according to different steel bar spacings. It is only necessary to move the positioning mechanism to the corresponding position along the electric slide rail 15, and then adjust the distance between each positioning block 13, so as to complete the segmented binding of the densified area and the sub-densified area.

[0035] like Figure 2 As shown, according to another embodiment of the utility model, an electric telescopic rod 16 is fixedly arranged vertically on the slider 8, and two sets of positioning mechanisms arranged along the length direction of the bottom plate are respectively fixedly connected to the moving ends of the electric telescopic rod 16. The vertical height of the positioning mechanism is adjusted as a whole by the electric telescopic rod 16, so that the longitudinal steel bars in the positioning groove 14 overlap the transverse steel bars, which is convenient for the subsequent use of iron wires to tie the contact parts of the transverse steel bars and the longitudinal steel bars.

[0036] The electric slide rail 15 and the slider 8 of the prefabricated beam and slab reinforcement positioning device of the utility model are purchased on the market, and technicians in the industry only need to install and operate them according to the accompanying instruction manual, without the need for creative work by technicians in this field.
