Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an automatic assembly and pouring equipment for prefabricated steel truss floor slabs. Background Technology

[0002] Prefabricated buildings are an important development direction of building industrialization. Among them, steel truss concrete composite floor slabs (i.e. steel truss floor deck slabs) are a key horizontal component. They are widely used in various types of buildings because they combine the high efficiency and high quality of factory prefabrication with the good integrity and seismic performance of on-site assembly.

[0003] Steel truss floor decking typically consists of a precast concrete base slab, welded three-dimensional triangular steel trusses, and a post-cast composite layer of concrete. One of its core production processes is cutting the pre-welded continuous steel trusses to a predetermined length and arranging them precisely in an array at predetermined intervals, then fixing them to the precast concrete base formwork (or the already cast precast base slab). The precision of this step directly determines the structural performance and product quality of the floor decking.

[0004] Currently, when connecting steel trusses to the base slab, ensuring uniform spacing and accurate positioning (especially consistent end extension lengths) of dozens or even hundreds of trusses across the entire slab surface relies heavily on the experience and skill level of the operators during the arrangement process. This requires repeated manual measurement, comparison, and adjustment, resulting in low automation. Even with the use of auxiliary positioning fixtures, manual pre-alignment and fine-tuning are still necessary when placing each truss into the slot or clamp to prevent tilting or displacement before final fixing. This cumbersome process makes it difficult to significantly improve production efficiency, and the consistency of product quality is greatly affected by human factors. At this point, in addition to the existing issue of array arrangement precision, the technical challenge lies in reliably positioning or connecting the lower chord steel bars of the truss to the pre-set grooves or connectors on the base plate while maintaining their verticality and preventing them from tipping over, all while ensuring high efficiency. Existing methods often require pre-setting complex positioning components on the base plate or employing a large amount of manual labor for auxiliary positioning and temporary support. This not only increases the complexity and cost of the base plate mold but also fails to fundamentally solve the problems of automation and precision control in the assembly process. Summary of the Invention

[0005] This invention provides an automated assembly and pouring equipment for prefabricated steel truss floor slabs, which can solve the following problems existing in the prior art: 1) The steel truss layout process is highly dependent on the experience and skill level of the operators, requiring repeated manual measurement, comparison and adjustment, resulting in low automation; 2) During the fixing process, the steel truss is also prone to skewing.

[0006] An automated assembly and pouring equipment for prefabricated steel truss floor slabs includes a hoisting module, which is used to hoist multiple sets of steel trusses onto the base slab at equal intervals. The steel truss includes a set of upper chord steel bars and two sets of lower chord steel bars arranged in a triangular orientation. The two sets of lower chord steel bars are symmetrically arranged below the upper chord steel bars. The lower chord steel bars are arranged on the side closer to the bottom plate. Several sets of connecting plates are also fixedly arranged at the bottom of the two sets of lower chord steel bars and the connecting plates are fixed to the bottom plate. The hoisting module includes a first hoisting section and a second hoisting section, which are symmetrically arranged to hoist two sets of steel trusses onto the base plate respectively.

[0007] Preferably, both the first positioning part and the second positioning part include at least one set of clamping parts for clamping and fixing the upper chord steel bars.

[0008] Preferably, several sets of reinforcing bars are welded and fixed between the two sides of the upper chord reinforcing bar and the lower chord reinforcing bar, and each reinforcing bar is welded and fixed between the two sides of the upper chord reinforcing bar and the lower chord reinforcing bar in a head-to-tail manner.

[0009] Preferably, each group of positioning parts has three sets of clamping parts.

[0010] Preferably, each of the clamping parts includes two sets of clamping plates arranged symmetrically, and the two clamping plates are respectively provided with arc-shaped grooves for embedding the upper chord steel bars on the side that is close to each other. The arc-shaped grooves are semi-circular structures. The clamping plates on both sides are connected to an adjustment mechanism that drives them to move closer together or further apart.

[0011] Preferably, the clamping plates on both sides are fixedly connected to the L-shaped adjustment frame on the side facing away from each other. The adjustment mechanism includes two sets of positioning plates arranged in parallel and symmetrical arrangement. Several sets of guide rods corresponding to each clamping part are fixedly arranged between the positioning plates. The other end of each L-shaped adjustment frame is slidably connected to the guide rod. Telescopic springs are symmetrically arranged on the guide rod. One end of the telescopic spring is fixedly connected to the positioning plate, and the other end is fixedly connected to the L-shaped adjustment frame. Among them, the side of the L-shaped adjustment frame on both sides that is away from each other is fixedly connected by a limiting frame, and the limiting frames on both sides are connected to a pushing mechanism that drives them to move closer to each other or away from each other.

[0012] Preferably, the first hoisting part and the second hoisting part further include U-shaped support frames, and the positioning plates on both sides are fixedly connected to the U-shaped support frames through L-shaped brackets, and the U-shaped support frames on both sides are arranged in parallel and symmetrical manner.

[0013] Preferably, the pushing mechanism includes an adjusting electric cylinder fixed to both ends of the U-shaped support frame. An adjusting plate is fixedly arranged at the driving end of the adjusting electric cylinder, and adjusting rods are fixedly arranged at both ends of the adjusting plate. Guide wheels are rotatably arranged at the ends of the adjusting rods. Inclined guide grooves are respectively opened at both ends of the limiting frame, and the guide wheels roll against the inclined guide grooves.

[0014] Preferably, baffles are fixedly arranged on the L-shaped brackets on both sides, and the baffles on both sides are spirally sleeved on the screw. The threads on both sides of the screw have opposite directions, and the end of the screw is fixedly connected to the servo motor.

[0015] Preferably, the hoisting module further includes a translation mechanism, the drive end of the translation mechanism is fixed to the lifting cylinder, the drive end of the lifting cylinder is fixedly connected to the lifting plate, and the side baffles are slidably connected to the rails fixedly arranged on the lifting plate.

[0016] This invention provides an automated assembly and pouring equipment for prefabricated steel truss floor slabs, which has the following beneficial effects: 1) After the steel truss assembly and welding are completed, the present invention first hoists and fixes the two sets of steel trusses respectively through the first hoisting part and the second hoisting part, and then transfers them to the base plate. The two sets of steel trusses are then fixedly connected to the base plate through the connecting plate. After the two sets of steel trusses are fixed, the present invention hoists the steel trusses again through the first hoisting part or the second hoisting part. It should be noted that after the first hoisting part hoists a set of steel trusses, the second hoisting part does not need to hoist. The second hoisting part only plays a positioning role. Specifically, when the first hoisting part places the steel truss on the base plate, the placement position needs to be determined based on the position of the steel truss after the second hoisting part is fixed to the base plate. Using this positioning method, the spacing between the two sets of adjacent steel trusses can be kept consistent, and no manual measurement and positioning is required. 2) Before the connecting plate of the steel truss of the present invention is connected to the bottom plate, the hoisting part is not separated from the steel truss, so that the hoisting part can always play the role of positioning the steel truss. During the connection process between the connecting plate and the bottom plate, the steel truss will never deviate, resulting in higher stability and more accurate positioning.

[0019] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] Example 1

[0021] like Figures 1 to 4 As shown in the figure, an automatic assembly and pouring equipment for prefabricated steel truss floor decking provided by an embodiment of the present invention includes a hoisting module, which is used to hoist multiple sets of steel trusses 2 at equal intervals onto the base plate 1. It should be noted that in this embodiment, after the steel trusses 2 are assembled and welded, the steel trusses 2 are hoisted onto the base plate 1 by the hoisting module, and the steel trusses 2 are fixedly connected to the base plate 1.

[0022] Specifically, in practical applications, the number of steel trusses 2 set on a set of base plates 1 is not limited, as long as it meets the actual application requirements; in this embodiment, each set of base plates 1 is provided with five sets of steel trusses 2. Furthermore, there is no limitation on the number of adjacent steel trusses 2.

[0023] In one embodiment of this invention, the steel truss 2 includes a set of upper chord steel bars 202 arranged in a triangular orientation and two sets of lower chord steel bars 201. The two sets of lower chord steel bars 201 are symmetrically arranged below the upper chord steel bars 202 and are arranged on the side closer to the bottom plate 1. Several sets of connecting plates 204 are also fixedly arranged at the bottom of the two sets of lower chord steel bars 201. The connecting plates 204 are fixed to the bottom plate 1. Specifically, in this embodiment, the connecting plates 204 can be fixedly connected to the bottom plate 1 by welding or bolting to ensure the stability of the connection. Among them, several sets of reinforcing bars 203 are welded and fixed between the two sides of the upper chord bar 202 and the lower chord bar 201. Each reinforcing bar 203 is welded and fixed between the two sides of the upper chord bar 202 and the lower chord bar 201 in a head-to-tail manner. Specifically, the stability of the steel truss 2 can be further improved by the arrangement of several sets of reinforcing bars 203.

[0024] In one embodiment of this invention, the hoisting module includes a first hoisting section and a second hoisting section, which are symmetrically arranged to hoist two sets of steel trusses 2 onto the base plate 1 respectively. It can be noted that, in this embodiment, after the steel trusses 2 are assembled and welded, the first and second hoisting sections respectively hoist and fix the two sets of steel trusses 2, then transfer them to the base plate 1, and fix the two sets of steel trusses 2 to the base plate 1 via connecting plates 204. Once the two sets of steel trusses 2 are fixed, this embodiment... For example, the steel truss 2 can be hoisted again by the first hoisting unit or the second hoisting unit. It should be noted that after the first hoisting unit hoists a set of steel trusses 2, the second hoisting unit does not need to hoist. The second hoisting unit only serves as a positioning unit. Specifically, when the first hoisting unit places the steel truss 2 on the base plate 1, the placement position needs to be determined based on the position of the second hoisting unit and the steel truss 2 fixed on the base plate 1. Using this positioning method, the spacing between two adjacent sets of steel trusses 2 can be kept consistent, and manual measurement and positioning are not required. It should also be noted that before the connecting plate 204 of the steel truss 2 is connected to the bottom plate 1, the hoisting part is not separated from the steel truss 2, so that the hoisting part can always play the role of positioning the steel truss 2. During the connection process between the connecting plate 204 and the bottom plate 1, the steel truss 2 will never shift, resulting in higher stability and more accurate positioning.

[0025] Example 2

[0026] Based on Example 1, please refer to Figures 2-5Both the first positioning part and the second positioning part include at least one set of clamping parts for clamping and fixing the upper chord steel bar 202. Specifically, in this embodiment, by setting multiple sets of clamping parts in each positioning part, the upper chord steel bar 202 is clamped and fixed simultaneously by multiple sets of clamping parts when positioning and fixing the upper chord steel bar 202, which makes the clamping stability of the upper chord steel bar 202 higher and ensures the stability of subsequent transfer.

[0027] It should be noted that each positioning part in this embodiment has three clamping parts to ensure the clamping and fixing effect.

[0028] In this embodiment, each clamping part includes two sets of symmetrically arranged clamping plates 406. An arc-shaped groove 407 for embedding the upper chord reinforcing bar 202 is provided on the side of each clamping plate 406 that is close to each other. The arc-shaped groove 407 has a semi-circular structure. The clamping plates 406 are connected to an adjustment mechanism that drives them to move closer together or further apart. It can be noted that when clamping and fixing the upper chord reinforcing bar 202 in this embodiment, the clamping plates 406 can first be moved further apart by the adjustment mechanism to both sides of the upper chord reinforcing bar 202, and then the clamping plates 406 can be moved closer together by the adjustment mechanism to achieve the effect of clamping and fixing the upper chord reinforcing bar 202.

[0029] As a further embodiment, the two clamping plates 406 on the opposite sides are fixedly connected to the L-shaped adjusting frame 404. The adjusting mechanism includes two sets of parallel and symmetrically arranged positioning plates 408. Several sets of guide rods 403 corresponding to each clamping part are fixedly arranged between the positioning plates 408. The other end of each L-shaped adjusting frame 404 is slidably connected to the guide rod 403. Telescopic springs 405 are symmetrically arranged on the guide rods 403. One end of the telescopic spring 405 is fixedly connected to the positioning plate 408, and the other end is fixedly connected to the L-shaped adjusting frame 404. The two L-shaped... The side of the adjustment frame 404 facing away from the center is fixedly connected by a limiting frame 5. The limiting frames 5 on both sides are connected to a pushing mechanism that drives them to move closer together or further apart. It can be noted that in this embodiment, by setting two sets of limiting frames 5 to fix multiple L-shaped adjustment frames 404 on both sides respectively, when the limiting frames 5 on both sides are adjusted to move closer together or further apart by the pushing mechanism, the synchronous adjustment of multiple sets of L-shaped adjustment frames 404 can be achieved. This embodiment does not require setting multiple adjustment devices to adjust the L-shaped adjustment frames 404 separately, which reduces costs and improves synchronization and stability.

[0030] Specifically, the first and second hoisting parts also include U-shaped support frames 4, with positioning plates 408 on both sides fixedly connected to the U-shaped support frames 4 via L-shaped brackets 402. The U-shaped support frames 4 on both sides are arranged in parallel and symmetrically. The pushing mechanism includes adjusting electric cylinders 401 fixed at both ends of the U-shaped support frames 4. Adjusting plates 503 are fixedly arranged at the driving end of the adjusting electric cylinders 401, and adjusting rods are fixedly arranged at both ends of the adjusting plates 503. Guide wheels 502 are rotatably arranged at the ends of the adjusting rods. Inclined guide grooves 501 are respectively opened at both ends of the limiting frame 5, and the guide wheels 502 roll against the inclined guide grooves 501. It can be explained that, in the initial state, based on the setting of the telescopic spring 405, the two limit frames 5 are in a state of being far apart. When it is necessary to adjust the two limit frames 5 to move closer together, the two adjustment plates 503 are driven to move closer together by the two adjustment electric cylinders 401. The adjustment plates 503 are driven to move closer together by the guide wheel 502 rolling against the inclined guide groove 501. Then, the two clamping plates 406 are driven to move closer together by the L-shaped adjustment frame 404, so as to achieve the effect of clamping and fixing the upper chord steel bar 202.

[0031] Based on different construction requirements, the spacing between the two sets of adjacent steel trusses 2 set on the base plate 1 is different. Baffles 305 are fixedly arranged on the L-shaped brackets 402 on both sides. The baffles 305 on both sides are spirally sleeved on the screw rod 303. The threads on both sides of the screw rod 303 have opposite directions. The end of the screw rod 303 is fixedly connected to the servo motor 304. It can be noted that in this embodiment, when adjusting the clamping distance of the clamping parts on both sides, the servo motor 304 can drive the screw rod 303 to rotate. The baffles 305 on both sides can move closer to each other or further away from each other on the screw rod 303 to achieve the effect of adjusting the distance between the two sets of clamping parts.

[0032] In this embodiment, the hoisting module also includes a translation mechanism 3. The driving end of the translation mechanism 3 is fixed to the lifting cylinder 301, and the driving end of the lifting cylinder 301 is fixedly connected to the lifting plate 302. The two side baffles 305 are slidably connected to the rails 306 fixedly arranged on the lifting plate 302. It can be noted that in this embodiment, when the fixed steel truss 2 is hoisted onto the base plate 1, the lifting cylinder 301 can drive the lifting plate 302 to rise and fall. The lifting plate 302 can then drive the two side clamping parts to rise and fall through the two side baffles 305, so as to place the fixed steel truss 2 onto the base plate 1.

[0033] In addition, the translation mechanism 3 can drive the clamped and fixed steel truss 2 to translate on the base plate 1 to adjust the hoisting position of the steel truss 2 on the base plate 1. The translation mechanism 3 can adopt a synchronous belt drive mechanism, and there is no limitation on this.

[0034] A casting method for an automated assembly and casting equipment for prefabricated steel truss floor slabs includes the following steps: Please see Figures 1-4The two sets of steel trusses were erected and welded together. The two sets of steel trusses 2 are hoisted, fixed, and transferred to the base plate 1 by the first hoisting part and the second hoisting part respectively; The two sets of steel trusses 2 are fixedly connected to the base plate 1 by the connecting plate 204; After the two sets of steel trusses 2 are fixed, the steel trusses 2 are hoisted again by the first hoisting part or the second hoisting part.

[0035] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
