Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly relates to an auxiliary device for the construction of prefabricated buildings. Background Art

[0002] At present, the country is vigorously promoting and applying prefabricated buildings to achieve sustainable development of construction. The main components of prefabricated structures are prefabricated in factories and assembled on site. Its advantages lie in factory production, standardized operation, and high quality assurance rate, which conform to the national development strategies of energy conservation, emission reduction, and building industrialization, and solve the problems existing in the traditional building production methods, such as high building energy consumption, large consumption of resources and energy, low scientific and technological content in the construction industry, and low production efficiency.

[0003] During the construction of the exterior wall of prefabricated buildings, special hoisting equipment is required for installation. During the hoisting process, when the precast wall panel is about 300 mm above the ground, it needs to be statically stopped. By bending down to observe, it is necessary to ensure that the reserved insertion bars on the ground are aligned with the grouting sleeves on the wall panel one by one. When there is a position deviation, it is necessary for workers to lie on the ground and then use a crowbar to straighten the insertion bars so that the insertion bars are inserted into the sleeves. Since the distance between the exterior wall and the ground is relatively small, during the process of observation and straightening of the insertion bars, construction workers need to lie almost completely on the ground for operation, which is very inconvenient and prone to lumbar injuries due to repeated lying down and standing up, thus leading to occupational diseases. Summary of the Invention

[0004] The purpose of the present invention is to provide an auxiliary device for the construction of prefabricated buildings, which can assist workers in observing whether the insertion bars on the ground are aligned with the grouting sleeves of the exterior wall of prefabricated buildings during the installation process and correcting the insertion bars.

[0005] The present invention is achieved by the following measures: An auxiliary device for the construction of prefabricated buildings, characterized in that it includes a bottom plate and a mirror provided at the middle position of one end of the bottom plate. Columns are symmetrically provided on both sides of the bottom plate, and the upper ends of the two columns are connected by a connecting column. An installation frame is rotatably provided on the connecting column.

[0006] The installation frame includes an installation plate and side plates symmetrically provided on both sides of the installation plate. A guide rod is provided between the two side plates, and clamping rods capable of reciprocating along the axial direction of the guide rod are provided at both ends of the guide rod. The clamping parts of the two clamping rods are located outside the front end of the mirror and higher than the mirror. The installation plate is rotatably provided on the connecting column.

[0007] The guide rod is a bidirectional screw rod, and the bidirectional screw rod is rotatably provided on the two side plates;

[0008] The clamping rod includes a first horizontal part, a vertical part is fixedly arranged below the front end of the first horizontal part, a second horizontal part facing the front end is arranged at the lower end of the vertical part, the front ends of the two second horizontal parts extend out of the mirror and the clamping parts are arranged on the opposite surfaces of the extending ends, and the first horizontal part and the vertical part are both located on both sides of the mirror;

[0009] The first horizontal part is arranged at both ends of the bidirectional screw through threaded connection. A guide post is arranged at the front end of the mounting plate through a bracket, and a guide groove cooperating with the guide post is arranged at the lower part of the vertical part; Any end of the bidirectional screw extends out of the side plate and the extending end is connected to a driving device, which can be a motor or a handwheel. Generally, a handwheel is adopted, so as to avoid the device being too heavy.

[0010] The clamping rods are all arranged on the bidirectional screw through threaded connection. When the bidirectional screw rotates, the two clamping rods move along the axis of the bidirectional screw and the guide groove moves along the guide post;

[0011] When the two clamping parts clamp the inserted bar, the vertical part, the second horizontal part and the clamping part are all located outside the mirror, so that when correcting the inserted bar, it does not affect the construction personnel's observation of the situation inside the mirror.

[0012] Or the guide rod is a fixed rod, and the fixed rod is fixedly arranged on the two side plates;

[0013] The clamping rod includes a first horizontal part, a vertical part is fixedly arranged below the front end of the first horizontal part, a second horizontal part facing the front end is arranged at the lower end of the vertical part, the front ends of the two second horizontal parts extend out of the mirror and the clamping parts are arranged on the opposite surfaces of the extending ends, and the first horizontal part and the vertical part are both located on both sides of the mirror;

[0014] The first horizontal part is sleeved on the fixed rod and the two first horizontal parts are connected by a spring. A guide post is arranged at the front end of the mounting plate through a bracket, and a guide groove cooperating with the guide post is arranged at the lower part of the vertical part;

[0015] When the two first horizontal parts are clamped, the spring is compressed, and the two clamping rods move along the axis of the fixed rod and the guide groove moves along the guide post;

[0016] When the two clamping parts clamp the inserted bar, the vertical part, the second horizontal part and the clamping part are all located outside the mirror.

[0017] A lamp facing the front end is arranged at the middle position of the guide post. The position of the lamp is preferably adjustable and can be turned on and off according to the on-site situation to improve the reflection effect of the mirror in a dark environment.

[0018] The mounting bracket and the connecting column are connected by a movable frame. The movable frame includes a ball hinge seat arranged at the central position of the connecting column. The ball hinge seat is connected with a ball hinge rod. A movable plate is arranged on the ball hinge rod. The mounting bracket is rotatably arranged on the movable plate through a bearing. A shaft cooperating with the bearing is arranged at the lower end of the mounting plate. Through holes are arranged on both the mounting plate and the movable plate, including pins that can be inserted into the through holes.

[0019] It further includes a limiting member of the movable frame. Thrust screws are symmetrically arranged on the connecting column through threaded connection. A limiting hole cooperating with the thrust screw is arranged on the movable plate. The upper end of the thrust screw can extend out of the connecting column and be inserted into the limiting hole.

[0020] A rectangular opening is opened on the bottom plate. A plurality of rollers capable of rotating back and forth are rotatably arranged in the rectangular opening.

[0021] The bidirectional screw is arranged near the front end of the first horizontal part. A handheld part is arranged at the rear end of the first horizontal part.

[0022] The fixed rod is arranged near the front end of the first horizontal part. A handheld part is arranged at the rear end of the first horizontal part.

[0023] The mirror is arranged on the bottom plate through an adjusting frame. The angle of the adjusting frame is adjustable. The adjusting frame can be connected to the bottom plate through bolts. By loosening the nuts, the angle adjustment can be realized.

[0024] Working principle: Insert the front end of the device, that is, one end of the mirror, into the space between the precast exterior wall panel and the ground. During actual use, the angle of the mirror can be adjusted according to the actual situation so that the construction workers can observe whether the inserted steel bars and the grouting sleeves are aligned on the outside. If they are not aligned, the positions of the two clamping rods can be adjusted, and the inserted steel bars are clamped by the two clamping parts. After clamping, step on the bottom plate manually, and then adjust the inserted steel bars;

[0025] Since the position of the inserted steel bars has been corrected before hoisting, there will be no large deviation after hoisting. Therefore, only a slight bend of the inserted steel bars is needed. So according to the actual situation, the device is designed with the following two usage states:

[0026] When the adjustment range is small and only the left-right direction adjustment is required, the thrust screw is inserted into the limiting hole. At this time, the movable frame cannot move, but the mounting bracket is rotatably arranged on the movable frame, and the correction of the inserted steel bars is realized by the left-right swing of the mounting bracket on the movable frame.

[0027] Since there are generally few mirrors and it is not easy to observe when they are too high, in this application, the height of the column is generally 0.6m - 1.2m. During manual operation, it is generally in a squatting position for operation.

[0028] When the adjustment position is uncertain, the setscrew is screwed out of the limiting hole, and the pin is inserted into the through holes of the movable plate and the mounting plate. At this time, the mounting bracket cannot rotate, and the mounting bracket and the movable bracket become an integral body. Since the movable bracket is arranged on the connecting column through a spherical hinge, the mounting bracket and the movable bracket can swing arbitrarily in multiple directions at this time, thereby realizing the adjustment of the two clamping rods at any angle. In this way, when the two clamping parts clamp the inserted steel bar, the clamping rods can be swung according to the actual situation to correct the position of the inserted steel bar.

[0029] The beneficial effects brought by the technical solution provided by the embodiment of the present invention are: assisting manual observation of whether the ground inserted steel bar is aligned with the external wall grouting sleeve through a mirror and correcting the inserted steel bar through the clamping rod arranged outside the mirror.

A guiding column 701 is arranged at the front end of the mounting plate through a bracket 7. A guiding groove 3021 matching the guiding column is arranged at the lower part of the vertical part 302;

[0052] When the two first horizontal parts 301 are clamped, the spring is compressed, and the two clamping rods 3 move along the axis of the fixed rod and the guiding grooves 3021 move along the guiding columns;

[0053] When the two clamping parts 304 clamp the inserted steel bars, the vertical part 302, the second horizontal part 303 and the clamping part 304 are all located outside the mirror 2.

[0054] A lamp 11 facing the front end is arranged at the middle position of the guiding column. The position of the lamp 11 is preferably adjustable and can be turned on and off according to the on-site situation to improve the reflection effect of the mirror 2 in a dark environment.

[0055] The mounting frame 4 and the connecting column 102 are connected by a movable frame 5. The movable frame 5 includes a ball hinge seat 901 arranged at the central position of the connecting column 102. The ball hinge seat 901 is connected with a ball hinge rod 902. A movable plate is arranged on the ball hinge rod 902. The mounting frame 4 is rotatably arranged on the movable plate through a bearing 12. A shaft matching the bearing 12 is arranged at the lower end of the mounting plate. Through holes are arranged on both the mounting plate and the movable plate, including pins 10 that can be inserted into the through holes.

[0056] It also includes a limiting part of the movable frame 5. Thumbscrews 8 are symmetrically arranged on the connecting column 102 through threaded connections.

[0061] Working principle: Insert one end of the front end of this device, that is, the mirror 2, into the space between the precast exterior wall panel and the ground. During actual use, the angle of the mirror 2 can be adjusted according to the actual situation so that construction workers can observe whether the inserted steel bars and grouting sleeves are aligned outside. If not, rotate the bidirectional screw 6. Since the thread directions at both ends of the bidirectional screw 6 are different, the positions of the two clamping rods 3 can be adjusted, and the inserted steel bars are clamped by the two clamping parts 304. After clamping, manually step on the bottom plate 1, and then adjust the inserted steel bars;

[0062] Since the position of the inserted steel bars has been corrected before hoisting, there will be no large deviation after hoisting. Therefore, only a slight bend of the inserted steel bars is needed. So according to the actual situation, this device is designed with the following two usage states:

[0063] When the adjustment range is small and only the left-right direction adjustment is required, the setscrew 8 is inserted into the limit hole, and the movable frame 5 cannot move at this time. However, the mounting frame 4 is rotatably arranged on the movable frame 5, and the inserted steel bars are corrected by the left-right swing of the mounting frame 4 on the movable frame 5.

In this way, when the two clamping parts 304 clamp the inserted steel bars, the clamping rods 3 can be swung according to the actual situation to correct the position of the inserted steel bars.

[0066] Embodiment 2:

[0067] Refer to Figures 1 - 8 , the difference between this embodiment and Embodiment 1 lies only in the guide rod. In this embodiment, the guide rod is a fixed rod, and the fixed rod is fixedly arranged on the two side plates;

[0068] The clamping rod 3 includes a first horizontal part 301. A vertical part 302 is fixedly arranged below the front end of the first horizontal part 301.

[0069] The first horizontal part 301 is sleeved on the fixed rod and the two first horizontal parts 301 are connected by a spring. A guide post 701 is arranged at the front end of the mounting plate through a bracket 7. A guide groove 3021 matched with the guide post is arranged at the lower part of the vertical part 302;

[0070] Clamp the two first horizontal parts 301, the spring is compressed, and the two clamping rods 3 move along the axis of the fixed rod and the guide groove 3021 moves along the guide post;

[0071] When the two clamping parts 304 clamp the inserted steel bars, the vertical part 302, the second horizontal part 303 and the clamping part 304 are all located outside the mirror 2.

[0072] Working principle: Insert one end of the front end of this device, i.e., the mirror 2, into the space between the precast exterior wall panel and the ground. During actual use, the angle of the mirror 2 can be adjusted according to the actual situation so that the construction workers can observe whether the inserted steel bars and the grouting sleeves are aligned outside. If they are not aligned, the positions of the two clamping rods 3 can be adjusted. Hold the holding part by hand and squeeze it towards the middle. The two clamping rods move towards the middle. At this time, the spring is compressed. The inserted steel bars are clamped by the two clamping parts 304. After clamping, step on the bottom plate 1 manually, and then adjust the inserted steel bars. After the adjustment is completed, release the clamping rod 3 and it will reset under the action of the spring.
