Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to an auxiliary device for installing a basket-type inclined roof composite plate. Background Art

[0002] In construction, the sloping roof of the prefabricated composite slab is not placed horizontally. During the construction process, it will slide down to varying degrees due to its own weight and the effect of the cast-in-place concrete on the composite slab. This phenomenon will cause gaps and leakage in the middle area of ​​the composite slab, which will reduce the waterproof performance of the roof and affect the overall quality. If the slide is serious, it may even cause the instability of the roof structure and affect the safety performance of the entire building. In order to prevent the sloping roof composite slab from sliding down, the traditional method is to embed steel bars at 1 / 3 of the short side of the composite slab and weld them to the embedded steel bars on the frame beam. However, this auxiliary installation method adds a large number of processes, making the operation complicated and labor-intensive. For this reason, it is necessary to improve the traditional auxiliary device for installing sloping roof composite slabs.

[0003] The technical solution in patent CN201921415238.5 includes a balance beam and connecting beams connected to both ends of the balance beam. The balance beam is placed on the ridge, and the connecting beams on both sides of the balance beam are connected to the corresponding composite panels through multiple clamp units, and the composite panels are installed and fixed on the inclined roof below them. This solution mainly solves the problem of installing and fixing the existing composite panels on the sloping roof when the composite panels are installed on the sloping roof. By connecting and fixing the composite panels to the connecting beams arranged on the left and right, the composite panels on both sides of the ridge can be installed and fixed on the sloping roof by offsetting the unbalanced force through their own weight, avoiding the problem of sliding and shifting of the composite panels, and facilitating the installation of composite panels on sloping roofs.

[0004] However, this solution uses the deadweight of the composite plate to maintain the angle of the two connecting beams of the balance beam. In actual operation, due to the influence of working conditions and manual operation, the angle is easily changed, causing the composite plate to slide to one side, affecting the overall quality. At the same time, a large number of clamps are required to fix the connecting beams and composite plates in this solution. When installing the clamps, the upper and lower clamps need to be aligned, and then the clamps are fixed with several nuts. The overall installation is cumbersome and complicated. After the roof is poured, the clamps and connecting beams will be poured into the roof together. On the one hand, this increases the deadweight of the roof, and on the other hand, most of the structure of the device of this solution cannot be reused, which makes the cost high and the market application limited. Utility Model Content

[0005] The utility model aims to overcome the defects of the prior art auxiliary device for installing the sloping roof composite panels, such as poor fixing effect, complicated operation and installation, high cost and much material waste, and provides a basket-type auxiliary device for installing the sloping roof composite panels to overcome the above defects.

[0006] In order to achieve the purpose of the above invention, the utility model is implemented through the following technical solutions:

[0007] A basket-type inclined roof composite panel installation auxiliary device, comprising:

[0008] Open flower basket, with flower basket screws at both ends, the spacing can be adjusted by rotating the flower basket screws;

[0009] A turnbuckle screw having at least one bent draw hook connected thereto;

[0010] The bent hook is set perpendicular to the turnbuckle screw and extends a distance to hook the truss steel bars of the composite plate;

[0011] During construction, when installing composite panels on sloping roofs, the composite panels are prone to slide down due to their own weight. For the traditional method, although the stability of the composite panels can be ensured by welding the embedded steel bars to the frame beams, the steel bars need to be buried in advance and the welding needs to be done manually after installation, which makes the overall process complicated. The existing auxiliary device for installing composite panels on sloping roofs connects the left and right composite panels through a balance beam, and only controls the angle between the composite panels by the weight of the composite panels. During construction, it is necessary to ensure that the balance beam is accurately located on the central axis of the roof, which places high demands on construction. When there is an external force, the angle is prone to change. In addition, since the beam body and the clamp are close to the truss steel bars of the composite panel, it is difficult to remove them after the roof is poured, resulting in this auxiliary device being able to be used once only, which increases the cost.

[0012] The utility model includes an open-body flower basket, with flower basket screws threadedly connected at both ends. The length of the device can be controlled by rotating the flower basket screws, and due to the characteristics of the flower basket structure, the two ends can withstand a large tensile force. A bent hook is provided along the vertical direction extending a distance from the end of the flower basket screw. The bent hook can be provided at the left and right ends, or only at one end, and the other end is fixed by welding or the like. When in use, the bent hook hooks the truss steel bars of the composite plate to prevent the composite plate from sliding. After pouring the roof, since the hook extends a distance from the auxiliary device, it is only necessary to cut off the part of the hook buried in the pouring layer to disassemble the auxiliary device, and the main part of the auxiliary device can be reused. The above is composed of the open-body flower basket, the flower basket screw and the bent hook together to form a flower basket unit.

[0013] Preferably, the bending hook is detachably connected to the turnbuckle screw by a long nut. Connecting the bending hook and the turnbuckle screw by the long nut not only ensures the overall strength of the auxiliary device, but also allows the bending hook to be quickly disassembled, facilitating the replacement and maintenance of the device, as well as the cutting of the bending hook after casting.

[0014] Preferably, the threads on both sides of the open-body flower basket are arranged in opposite directions, so that the flower basket screws on both sides can be rotated into the open-body flower basket, and the overall length of the auxiliary device can be adjusted, which is convenient for the operator to adjust the spacing between the overlapping plates when tightening the overlapping plates.

[0015] Preferably, when the basket screw is connected with two bent hooks, the openings of the bent hooks are arranged in opposite directions. When two bent hooks are provided, the opening directions of the two bent hooks are opposite, which helps to disperse and balance the pulling force generated by the weight, reduce the problem of excessive local stress caused by concentrated pulling force, and help prevent the laminated plate from shaking when subjected to external force. In addition, when installing the auxiliary device, the openings in opposite directions can also prevent the auxiliary device from interfering with other devices, making it easier to install it in place.

[0016] Preferably, the bending hook has a bending angle of 90°, forming an L-shaped hook. Since the auxiliary device is installed with the composite plate after the composite plate reaches the installation position, the L-shaped hook can be directly hooked on the truss steel bar of the composite plate after the length of the basket screw is set, which is convenient for installation. In addition, the bending hook can be directly processed by bending the round steel twice by 90°, which is convenient for the manufacture of the auxiliary device.

[0017] Preferably, two basket units are connected, and a rotating steel sheet fixedly connected to the basket screw is provided on one side of the basket unit away from the bent hook; the two basket units are rotatably connected at the rotating steel sheet through an angle adjustment device. When installing two overlapping plates at the junction of the top of the sloping roof, the two bent hooks respectively hook the overlapping plates on both sides of the roof, thereby preventing the overlapping plates on both sides from sliding down.

[0018] As a further preferred embodiment, a connection hole is provided in the middle of the rotating steel sheet, and the angle adjustment device includes a tightening bolt with adjustable tightness; the tightening bolt cooperates with the connection hole, so that the two basket units are connected in rotation. After the two basket units hook the overlapping plate, during the process of rotating the basket screw, the two basket units may rotate relative to each other, affecting the clamped angle, so that the tension at the left and right ends is unbalanced, causing the overlapping plate to slide and deviate from the predetermined position. Therefore, a tightening bolt is provided on the angle adjustment device, and after the basket unit hooks the overlapping plate, the tightening bolt is tightened to limit the rotation of the angle adjustment device, thereby preventing the angle clamped by the two basket units from changing.

[0019] As a further preferred embodiment, the edge of the rotating steel sheet is also provided with teeth symmetrically arranged in the upper and lower parts, and the angle adjustment device further comprises a control card plate for matching with the teeth to adjust the angles of the two basket units. After tightening the fastening bolts, the control card plate is clamped at the teeth of the rotating iron sheet to further improve the torsion resistance of the angle adjustment device, and by observing the deformation of the control card plate, it can also be intuitively seen whether the angle of the auxiliary installation device has changed.

[0020] As a further preferred embodiment, the control card plate is symmetrically provided with trapezoidal notches that can be engaged with the tooth openings. When in use, the trapezoidal notches are engaged with the tooth openings to hinder the card plate from moving perpendicularly to the rotating steel sheet, making the overall structure more stable.

[0021] As a further preferred embodiment, when two basket units are used to install the roof composite board, the opening directions of the two bent hooks of the two basket units are arranged in opposite directions. When the auxiliary device is placed on the roof and the left and right ends are respectively hooked on the composite board, the auxiliary device is subjected to a large tensile force, and the opening directions of the two bent hooks are opposite, which helps to disperse and balance the tensile force generated by the heavy object, reduce the problem of excessive local stress caused by concentrated tensile force, and help prevent the composite board from shaking when subjected to external force.

[0022] Therefore, the utility model has the following beneficial effects:

[0023] (1) The utility model uses a basket-like structure to facilitate adjustment of the spacing between the laminated plates, and can withstand the tension generated by the laminated plates, thereby effectively preventing the laminated plates from sliding down;

[0024] (2) The utility model can adapt to the installation of composite panel roofs with different slopes by using the combination of two basket units of the preferred solution;

[0025] (2) The utility model has a relatively simple structure, is quick to install, and the materials used are easy to obtain. In addition, the main structure of the device can be reused after the roof is poured, which is low in cost and is conducive to promotion and application in production practice.

A person of ordinary skill in the art will be able to implement the utility model based on these descriptions. In addition, the embodiments of the utility model involved in the following description are usually only embodiments of a part of the utility model, rather than all of the embodiments. Therefore, based on the embodiments in the utility model, all other embodiments obtained by a person of ordinary skill in the art without making creative work should fall within the scope of protection of the utility model.

[0034] like Figure 1-2 As shown, the utility model includes a basket unit 1, which is connected by an open basket 2, a basket screw 3, a bent hook 4 and a long nut 5. The size of the openings at both ends of the open basket 2 is set to 16 mm, and the thread directions on both sides are opposite. The reason is that the diameters of the screws commonly used in construction are 12 mm, 14 mm and 16 mm. A 16 mm screw is selected as the basket screw, which facilitates the collection of device materials while the auxiliary device can withstand greater tension. The openings at both ends are respectively threadedly connected to the basket screw 3. The basket screws 3 at both ends are connected to the bent hook 4 with a bending angle of 90° through the long nut 5. The bent hook 4 extends in the vertical direction of the basket screw 3, and the openings of the bent hook 4 at both ends are installed in opposite directions.

[0035] The usage process of this embodiment is as follows:

[0036] When installing the sloping roof composite panels on the same plane, the bent hooks 4 at both ends of the auxiliary device are used to hook the truss steel bars of two adjacent composite panels on the same plane, and then the characteristics of the flower basket are used to rotate the flower basket screws 3 on both sides of the auxiliary device to adjust the spacing so that the two adjacent composite panels are tightened. Multiple auxiliary devices can be adjacently set on the composite panel truss steel bars, and the spacing is controlled at 1 meter. After the concrete is poured, the long nut 5 is rotated to remove the open body flower basket 2 and the flower basket screw 3 for reuse, and the exposed bent hook 4 is cut using a cutting machine.

[0037] As another embodiment, Figure 3-6As shown, two flower basket units 1 are connected for use. A rotating steel sheet 11 fixedly connected to the flower basket screw 2 is also provided on the side of the flower basket unit 1 away from the bending hook 4. A connecting hole 12 is provided in the middle of the rotating steel sheet 11. The two rotating steel sheets 11 are connected by a fastening bolt 13 with adjustable tightness, so that the two flower basket units 1 are connected in rotation. The edge of the rotating steel sheet 11 is also provided with a tooth opening 14 symmetrical up and down, and a control card plate 13 with a trapezoidal notch 16 is engaged with the tooth opening 14 through the notch. The bending hooks 4 on both sides are connected to the flower basket screw through long strip nuts, and the opening directions are set in opposite directions.

[0038] The specific use process of this embodiment is as follows:

[0039] When installing the two composite panels at the junction of the top of the sloping roof, first connect the two auxiliary devices, and then adjust the angle by loosening the fastening bolts 13 according to the slope of the sloping roof. After the angle adjustment is completed, tighten the fastening bolts 13, and use the control card plate 13 to clamp the tooth mouth 14 through the trapezoidal notch 16. At this time, the angle adjustment is completed. Then use the bent hooks 4 on both sides of the auxiliary device to hook the outermost trusses of the symmetrical sloping roof composite panels on the top, and then rotate the basket screw 3 to tighten and fix the composite panels on both sides. At this time, it can be determined whether the angle changes by controlling whether the card plate is deformed. After the auxiliary device is installed, concrete can be poured. After the pouring is completed, the long strip nuts 5 on both sides are rotated to remove the main body of the device, and the exposed bent hooks 4 are cut with a cutting machine.
