Description

Technical Field

[0001] The utility model relates to a lattice beam template, in particular to an assembled lattice beam template, and belongs to the technical field of slope reinforcement equipment. Background Art

[0002] Slope refers to the slope surface with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. For severely weathered rock slopes and high soil slopes with stable slopes, slope frame beams are needed to protect the slopes. Existing slope frame beam templates mostly use wooden templates, which have problems such as long construction period, low installation efficiency, and high labor costs during on-site construction. In addition, due to the brittle texture of wooden templates, there is also a risk of easy mold breakage during on-site construction, which can easily lead to construction safety accidents. If a full steel structure template is used, there are problems such as heavy weight, high prefabrication cost, and inability to adjust according to on-site conditions, as well as the need for a crane to assist in installation during on-site installation. In addition, due to the inclination of the on-site slope construction, the steel template is difficult to vibrate, which can easily lead to substandard frame beam quality and safety accidents.

[0003] In addition, the existing lattice beams will inevitably be damaged and cracked after long-term use, and the shape and size of the lattice beams in different periods and regions are different. When they need to be repaired, preparing templates on site according to the terrain is not only time-consuming and labor-intensive, but the prepared templates are basically disposable and difficult to recycle, which greatly increases the repair cost.

The top plate is arranged horizontally, and two side plates are symmetrically arranged on the lower surface on both sides of the top plate in the width direction, that is, the top plate and the two side plates together form a U-shaped structure with the opening facing downward. A grouting and accessory interface is provided on the top plate. A mobile vibration device is detachably mounted on the grouting and accessory interface (when grouting is required, the grouting and accessory interface is used as a grouting port, and after the grouting is completed, the grouting and accessory interface is used as an installation connection port of the mobile vibration device). It should be noted that the mobile vibration device can be any existing vibrating equipment, except that a connecting seat matching the grouting and accessory interface is provided at the bottom thereof.

[0007] The top plate includes a left flat plate, a middle plate and a right flat plate. A side plate is hinged to the left lower surface of the left flat plate and the right lower surface of the right flat plate (i.e., the side plate can rotate, thereby facilitating the adjustment of the angle between the side plate and the top plate). The left flat plate is connected to the right flat plate through the middle plate, and the left flat plate and the middle plate, as well as the right flat plate and the middle plate are all slidably connected (i.e., the left flat plate and the right flat plate can slide relative to the middle plate, thereby adjusting the horizontal distance between the left flat plate and the right flat plate).

[0008] Preferably, a horizontal slide groove is provided at the right end of the left flat plate and the left end of the right flat plate. The two ends of the middle web are respectively installed in the horizontal slide groove at the right end of the left flat plate and the horizontal slide groove at the left end of the right flat plate, and can slide relative to the two horizontal slide grooves. The horizontal width of the middle web is not less than the total width of the two horizontal slide grooves.

[0009] Preferably, a fixed shaft tube is disposed on the upper surface of the left plate and the upper surface of the right plate, respectively, and the central axes of the two fixed shaft tubes overlap and extend along the width direction of the top plate. The two fixed shaft tubes are connected by a screw and an adjusting nut. The axial spacing between the left plate and the right plate is adjusted by the fixed shaft tube, the screw and the adjusting nut, thereby adjusting the width of the top plate.

[0010] Preferably, angle adjustment fixtures are provided at the junctions of the two side panels and the top panel, and the size of the inner angle formed between the side panels and the top panel is adjusted by the angle adjustment fixtures.

[0011] Preferably, the angle adjustment fixture comprises a fixed portion and a movable portion. The fixed portion is arranged on the upper surface of the top plate, and the outer end of the fixed portion extends to the edge of the top plate. The movable portion is arranged on the side plate, and the upper end of the movable portion is hinged to the outer end of the fixed portion. The fixed portion drives the movable portion to drive the side plate to rotate around the edge of the top plate with the upper end side of the side plate as the rotation axis.

[0012] Preferably, anchors are provided at the lower part of the outer surface of the side panels, and a plurality of anchors are evenly distributed along the length direction of the side panels.

[0013] Preferably, the anchor comprises a cutting tube and an anchor rod. The cutting tube is fixedly arranged at the lower part of the outer surface of the side plate. The anchor rod passes through the cutting tube and then is inserted downward into the soil. The upper end of the anchor rod is a "7"-shaped bending structure.

[0014] Preferably, the side panels include an upper side panel and a lower side panel. The upper end of the upper side panel is hinged to the lower surface of the top panel. The lower end of the upper side panel is hinged to the upper end of the lower side panel. The upper and lower parts of the upper side panel are foldable structures, and the folding points of the two upper side panels on both sides of the same top panel are at different heights, so that the two side panels are successively located below the lower surface of the top panel in the folded state.

[0015] Preferably, a pressure homogenizing liquid containing chamber is provided inside the upper side plate. An active cavity groove with an open lower end is provided inside the lower side plate, a movable side plate is arranged in the active cavity groove, and a sealing rubber ring is arranged between the upper end of the movable side plate and the inner wall of the active cavity groove. The top of the movable cavity groove is upwardly connected to the pressure homogenizing liquid containing chamber through a connecting pipe, and a connecting valve is arranged on the connecting pipe. The pressure homogenizing liquid containing chamber adjusts the amount of pressure homogenizing liquid entering and exiting the active cavity groove through the connecting valve, and then adjusts the lifting and lowering of the movable side plate in the active cavity groove to achieve the adjustment of the height of the side plate.

[0016] Preferably, the end portions at both ends of the top plate and / or the side plates in the length direction are respectively "convex" and "concave" structures that match each other.

[0017] Preferably, matching assembly joints and assembly buckles are respectively provided on the outer side walls at both ends of the top plate and / or the side plates in the length direction.

[0018] In the present invention, the width direction refers to the horizontal direction from the two ends of the top plate to the two side plates. The length direction refers to the horizontal direction perpendicular to the width.

[0019] In the present invention, the top plate includes a left flat plate, a middle plate and a right flat plate, and the middle plate is movably embedded in two horizontal slide grooves arranged opposite to the left and right flat plates. The width of the top plate in the horizontal plane is adjusted by the different depths (depths in the width direction) of the two ends of the middle plate embedded in the two horizontal slide grooves, so as to facilitate the casting and repair of frame beams of different widths. It should be noted that although the middle plate can slide in the horizontal slide groove, it cannot slide by itself without the action of external force, that is, the sliding of the middle plate requires a little additional external force.

[0020] Furthermore, in order to better adjust the width of the top plate, fixed shaft tubes with opposite axes are respectively arranged on the surfaces of the left flat plate and the right flat plate, and threads are arranged inside the fixed shaft tubes. The screw rod passes through the two fixed shaft tubes in turn to achieve a fixed connection between the left flat plate and the right flat plate (after fixation, the middle web plate cannot move freely without external force), and an adjusting nut is arranged on the screw rod so that the shaft rod is fixed on the fixed shaft tube after passing through the fixed shaft tube.

[0021] In the utility model, the top end of the side panel is hinged to the lower surface of the top panel (or the end in the width direction of the top panel), that is, the side panel can be rotated with its upper end as the rotation axis, so that the U-shaped inner groove formed by the side panel and the top panel is a rectangular or trapezoidal structure, thereby meeting the applicability to lattice beams of different external structures, thereby improving the recycling value and practicality of the template.

[0022] Furthermore, in order to improve the size adjustment and stability of the inner angle (i.e., the bottom angle of the U-shaped inner groove) after the side panel is rotated relative to the top panel, an angle adjustment fixture is provided on the side walls of the side panel and the top panel at their adjacent locations. The angle adjustment fixture is used to quickly adjust and fix the size of the inner angle, thereby improving construction efficiency.

[0023] In the utility model, at least one anchor is provided at the lower part of the outer wall of any side plate, and the anchor comprises a plugging tube and an anchor rod. The plugging tube is welded to the side plate, and the anchor rod passes through the plugging tube and then is inserted downward into the soil to achieve the fixation between the side plate and the soil. The upper end of the anchor rod is a "7"-shaped bending structure, so that workers can quickly insert the anchor rod into the soil by stepping on it.

[0024] In the present invention, the side panels include an upper side panel and a lower side panel, wherein the upper and lower parts of the upper side panel are foldable structures (any existing folding method can be used in the present invention), that is, through the folding action between the upper and lower parts of the upper side panel, the side panels can be folded below the lower surface of the top panel for easy transportation and storage. It should be noted that the heights of the folding points of the two upper side panels located on both sides of the same top panel are different (in the vertical direction, the distance between the two folding points in the vertical direction is slightly greater than the thickness of a single side panel), so that the two side panels are successively located below the lower surface of the top panel in the folded state.

[0025] In the utility model, a movable cavity (inverted U-shaped structure) with an open lower end is provided inside the lower side plate, and a movable side plate is arranged in the movable cavity. A sealing rubber ring is arranged between the upper end of the movable side plate and the inner wall of the movable cavity, that is, when the movable side plate moves in the movable cavity, a closed chamber is always formed between its upper end and the movable cavity. The closed chamber is also connected to the closed pressure homogenizing liquid containing chamber arranged inside the upper side plate through a connecting pipe and a connecting valve. By applying pressure (for example, external pressure), the liquid in the pressure homogenizing liquid containing chamber flows into the closed chamber of the lower side plate, thereby pushing the movable side plate downward to the outside of the lower end of the movable cavity of the lower side plate (conversely, it is recovered into the movable cavity of the lower side plate), thereby realizing the adjustment of the height of the entire side plate to meet the casting and repair operations of lattice beams with different heights.

[0026] In the present invention, the ends of the top plate and / or the side plate in the length direction are respectively "convex" and "concave" structures that match each other, and the outer side walls of the top plate and / or the side plate in the length direction are respectively provided with matching assembly joints and assembly buckles (any existing snap-fit ​​structures that can achieve fixed connection can be used). The design of the "convex" and "concave" ends can realize the rapid installation of the template, and the assembly joints and assembly buckles can be used for rapid fixation. In other words, the length of the template of the present invention can be adjusted in time, thereby meeting the casting and repair operations of lattice beams with different lengths.

[0027] Compared with the prior art, the beneficial technical effects of the utility model are as follows:

[0028] 1: The assembled lattice beam formwork of the utility model can be quickly disassembled and installed, and can be reused, which saves time and effort and has high production efficiency; in addition, through the adjustable settings of width, length, height and inner angle, it can meet the casting and repair operations of lattice beams with different widths, lengths, heights and inclined sides, and has strong applicability.
