Description

Technical Field

[0001] The present invention belongs to the field of construction method boxes, and particularly relates to a construction method box for strengthening by pasting steel plates. Background Art

[0002] A construction method box is not a physical container in the traditional sense, but a tool or platform that integrates, encapsulates, and visually displays various construction methods through digital and modular means. For example, various teaching construction method boxes developed by Zhejiang Taixue Technology display corresponding building node structures through corresponding models and QR code systems to assist teaching and training. Among them, the model enables students to intuitively see the structure of the building node. Scanning the QR code pasted on or near the model can view the introduction and construction steps of the building node on the mobile phone; the "Integrated Construction Method Box" at the Shenzhen Creative Design Week integrates design and construction technologies in digital form and provides a full-case assembly solution.

[0003] The beam-column structure is a common building node. As shown in Figure 8 and Figure 9 , it includes two columns 1, and a cross beam 2 is provided between the two columns 1. When the connection strength between the cross beam 2 and between the cross beam 2 and the column 1 is insufficient, the columns 1 and the cross beam 2 are strengthened by pasting steel plates, and the steel plates are connected to the cross beam 2 or the column 1 through anchor bolts 7.

[0004] The steel plate includes a bottom plate 3 located at the bottom of the cross beam 2 and having the same length as the cross beam 2; a plurality of U-shaped bottom plates 4 arranged side by side at the end of the bottom plate 3, and the U-shaped bottom plates 4 cover the cross beam 2; pressing plates 19 located on both sides of the end of the cross beam 2, and the pressing plates 19 press the corresponding side arms of the plurality of U-shaped plates against the cross beam 2, and some of the anchor bolts 7 on the pressing plates 19 share the anchor bolts 7 on the U-shaped bottom plates 4; an L-shaped plate 20 located on the upper side of the end of the cross beam 2, and the L-shaped plate 20 connects the column 1 and the cross beam 2; a U-shaped side plate 21 located above the end of the cross beam 2, and the U-shaped side plate 21 presses the L-shaped plate 20 against the column 1, and the U-shaped side plate is fixed to the column 1.

[0005] For the cross beam, the top is stressed, resulting in the bending direction of the cross beam being downward in the middle and upward at both ends. The reinforcement effect of the cross beam mainly depends on the bottom plate and the U-shaped side plate. The number and spacing of the anchor bolts 7 on the bottom plate have an important impact on the reinforcement degree of the cross beam; the number and position of the anchor bolts 7 on a single U-shaped side plate are fixed, both are two, and are respectively located at both ends of the top of the U-shaped side plate. The number and spacing of the U-shaped side plates will also have an important impact on the reinforcement degree of the cross beam. Therefore, when designing the reinforcement scheme, after the thickness and size of different steel plates are designed, it is also necessary to adjust the number and spacing of the anchor bolts 7 on the bottom plate and the number and spacing of the U-shaped side plates on this basis to obtain a better solution.

[0006] In order to facilitate students to better master the structure of bonding steel plates for beam-column structures, there are already corresponding construction method boxes available. However, these can only allow students to visually see the structure after reinforcement, but cannot adjust the number and spacing of the anchor bolts 7 on the bottom plate, nor the number and spacing of the U-shaped side plates. Even if adjustments are forcibly made through violent disassembly and assembly, it is impossible to know the change in the reinforcement state of the crossbeam before and after the adjustment, which is not conducive to on-site teaching. Summary of the Invention

[0007] The purpose of the present invention is to provide a construction method box for bonding steel plates for reinforcement, which has the advantage of improving the effect of on-site teaching.

[0008] The technical solution of the present invention: The construction method box for bonding steel plates for reinforcement includes a model and a two-dimensional code system. The model includes two columns, a crossbeam is provided between the two columns, a bottom plate is provided at the bottom of the crossbeam, a plurality of U-shaped bottom plates arranged side by side are provided at the bottoms of both ends of the crossbeam, pressing plates for pressing the U-shaped bottom plates are provided on both sides of both ends of the crossbeam. The crossbeam is made of a flexible material, chutes are provided on both sides and the bottom surface of the crossbeam, sliders are provided in the chutes, anchor bolts 7 extending outward from the chutes are provided on the sliders, nuts are provided on the anchor bolts 7, and long holes through which the corresponding anchor bolts 7 pass are provided on the bottom plate and the pressing plates.

[0009] In the aforementioned construction method box for bonding steel plates for reinforcement, the nut, the anchor bolt 7, and the crossbeam are all made of insulating materials, the slider is made of a conductive material, and the cross-section of the chute is convex-shaped;

[0010] The model further includes a detection mechanism for the anchor bolt 7. The detection mechanism includes a controller. A plurality of detection points are provided in the chute, and the plurality of detection points are distributed along the long direction of the chute. Each detection point is composed of two detection contacts, and the two detection contacts are respectively located on the stepped surfaces on both sides of the chute. The detection contacts are connected to the input end of the controller.

[0011] In the aforementioned construction method box for bonding steel plates for reinforcement, flexible and insulating load plates are provided on the stepped surfaces on both sides of the chute, and the detection contacts are formed by electroplating at multiple places on the load plates.

[0012] In the aforementioned construction method box for bonding steel plates for reinforcement, the two-dimensional code system includes a signal conversion module. The controller is connected to a finite element analysis module through the signal conversion module, and the finite element analysis module is connected to a display module.

[0013] In the aforementioned construction method box for bonding steel plates for reinforcement, a groove is provided on the side wall of the slider facing the stepped surface of the chute, and an insulating elastic body is provided in the groove.

[0014] In the aforementioned construction method box for bonding steel plates for reinforcement, the elastic body is a strip-shaped elastic piece. The middle of the elastic piece is fixed to the slider, and the two ends of the elastic piece are respectively connected to the load plates on both sides of the slider.

[0015] Compared with the prior art, based on the existing construction method box for strengthening the beam-column structure by pasting steel plates, the present invention improves both the model and the two-dimensional code system. In the model, the anchor bolts on the bottom plate and the U-shaped bottom plate are both movable, so that the spacing of the anchor bolts 7 on the bottom plate and the spacing of the U-shaped side plates are adjustable. The anchor bolts are locked by nuts. By loosening the nuts, the fastening tension of the anchor bolts is lost, simulating the change in the reduction of the number of anchor bolts, so that the number of anchor bolts on the bottom plate is adjustable, and the number of U-shaped side plates is adjustable. After adjusting the number and spacing of the anchor bolts 7 on the bottom plate and the number and spacing of the U-shaped side plates, a load is applied to the cross beam. Since the cross beam is made of a flexible material, the degree of deformation of the cross beam is visually reflected, which is beneficial to teaching. At the same time, a signal conversion module is added to the two-dimensional code system, and the controller is connected to the finite element analysis module through the signal conversion module, which can display more specific information of the cross beam, further improving the teaching effect. In summary, the present invention has the advantage of being able to improve the on-site teaching effect. Description of the Drawings

Detailed Embodiments

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but it shall not be used as a basis for limiting the present invention.

[0027] Embodiment: The steel plate bonding reinforcement construction method box includes a model and a two-dimensional code system.

[0028] As Figure 1 shown, the model includes two columns 1, a cross beam 2 is arranged between the two columns 1, steel plates are arranged on the columns 1 and the cross beam 2 for reinforcement, and each steel plate is connected to the cross beam 2 or the column 1 through several anchor bolts 7.

[0029] The steel plate includes a bottom plate 3 located at the bottom of the cross beam 2 and having the same length as the cross beam 2; a plurality of U-shaped bottom plates 4 arranged side by side at the end of the bottom plate 3, and the U-shaped bottom plates 4 cover the bottom surface and both side walls of the cross beam 2; pressing plates 19 located on both sides of the end of the cross beam 2, and the pressing plates 19 press the corresponding side arms of the plurality of U-shaped plates towards the cross beam 2, and some of the anchor bolts 7 on the pressing plates 19 share the anchor bolts 7 on the U-shaped bottom plates 4; an L-shaped plate 20 located on the upper side of the end of the cross beam 2, and the L-shaped plate 20 connects the column 1 and the cross beam 2; a U-shaped side plate 21 located above the end of the cross beam 2, and the U-shaped side plate 21 presses the L-shaped plate 20 towards the column 1, and the U-shaped side plate is fixed to the column 1.

[0030] The cross beam 2 is made of rubber or silica gel material, sliding grooves 5 are provided on both sides and the bottom surface of the cross beam 2, sliders 6 are arranged in the sliding grooves 5, anchor bolts 7 extending outward from the sliding grooves 5 are arranged on the sliders 6, nuts 8 are arranged on the anchor bolts 7, and long holes 9 through which the corresponding anchor bolts 7 pass are provided on the bottom plate 3 and the pressing plates 19.

[0031] Both the nut 8 and the anchor bolt 7 are made of plastic material, the slider 6 is made of copper material, and the cross section of the sliding groove 5 is convex-shaped;

[0032] The model further includes a detection mechanism for the anchor bolts 7. The detection mechanism includes a controller 10 with networking function, such as XINJE XD3E series, Siemens S7-200 SMART series. A plurality of detection points are provided in the sliding groove 5 on the horizontal side of the cross beam and the sliding groove at the bottom of the cross beam. The plurality of detection points are distributed along the length direction of the sliding groove 5. The detection point is composed of two detection contacts 12, and the two detection contacts 12 are respectively located on the step surfaces on both sides of the sliding groove 5, and the detection contacts 12 are connected to the input end of the controller 10.

[0033] For the sliding groove 5 on the horizontal side of the cross beam and the sliding groove at the bottom of the cross beam, flexible and insulating load plates 13 are provided on the step surfaces, and the detection contacts 12 are formed by electroplating at multiple places on the load plates 13.

[0034] On the side wall of the slider 6 facing the step surface of the chute 5, there are two grooves 17, and an insulating elastic body 18 is arranged in the grooves 17. The elastic body 18 is a strip-shaped elastic sheet. The middle of the elastic sheet is fixed to the slider 6, and the two ends of the elastic sheet are respectively slidably connected to the load plates 13 on both sides of the slider 6.

[0035] The two-dimensional code system includes a two-dimensional code pasted on or near the model and a signal conversion module 14. The controller 10 is connected to the finite element analysis module 15 through the signal conversion module 14, and the finite element analysis module 15 is connected to the display module 16.

[0036] Working principle: The present invention is improved on the basis of the existing construction method box, and the main improvement points are as follows:

[0037] A chute 5 is arranged on the cross beam 2, and long holes are arranged on the bottom plate 3 and the pressing plate 19, so that the anchor bolts 7 on the bottom plate 3 can move, and the anchor bolts 7 on the pressing plate 19 can move, so that the distance changes. The movement of the anchor bolts 7 on the pressing plate 19 also means the movement of the corresponding U-shaped bottom plate 4, so that the distance changes.

[0038] When the nut 8 is loosened, the anchor bolt 7 does not play a fixing role and can be regarded as non-existent. At the same time, the elastic body 18 separates the slider 6 from the load plate 13, and the two detection contacts 12 on both sides of the slider 6 are not conducted. The controller 10 does not detect the input signal of the anchor bolt 7 on the corresponding input port, and the detection mechanism cannot detect the anchor bolt 7. Therefore, after the nut on the bottom plate 3 is removed or loosened, it can be regarded as a reduction in the number of anchor bolts on the bottom plate 3, and vice versa. For the U-shaped bottom plate 4, it can be removed and installed after removing the nut. Therefore, in the embodiment, the number of anchor bolts on the bottom plate 3 and the number of U-shaped bottom plates 4 are variable.

[0039] Since the positions of each detection point are fixed, the controller 10 can know the number and position of the anchor bolts on the bottom plate 3 and the number and position of the U-shaped bottom plates 4 according to the signal quantity and the signal output port.

[0040] Build a computational model of the model in the finite element analysis module 15. The finite element analysis module 15 can use software such as CalculiX, ABAQUS, SAP2000, 3D3S, etc. Set the dimensions and elastic modulus of the cross beam. Among them, the number and spacing of the anchor bolts 7 on the bottom plate and the number and spacing of the U-shaped side plates are variables. The controller 10 converts the number and position of the anchor bolts on the bottom plate 3 and the number and position of the U-shaped bottom plate 4 into the input format of the finite element analysis module 15 through the signal conversion module 14, inputs it into the finite element analysis module 15, attaches it to the cross beam, and uses the finite element analysis module 15 to perform a force analysis. Scan the QR code, and the corresponding analysis results are displayed to the students through the display module 16. For example, when scanning the QR code with a mobile phone, the results are displayed on the screen of the mobile phone. Hyperlinks can be set on the display interface. After clicking the hyperlink, the reinforcement process of the bonded steel plate is played or displayed. Thus, after adjusting the number and spacing of the anchor bolts 7 on the bottom plate and the number and spacing of the U-shaped side plates, students can quickly and intuitively perceive the reinforcement state of the cross beam.

[0041] In another way, apply a fixed load at the fixed position of the cross beam, change the number and spacing of the anchor bolts 7 on the bottom plate and the number and spacing of the U-shaped side plates, and students can also observe different deformation degrees of the cross beam and clearly perceive the reinforcement state of the cross beam.
