Description

Technical Field:

[0001] The present invention relates to the field of prefabricated component hoisting and positioning tools, and particularly to a device for installing and positioning the wall of an assembled integrated pipe gallery, as well as an installation and use method thereof. Background Art:

[0002] Compared with the traditional cast-in-situ integrated gallery construction, the assembled integrated pipe gallery construction has obvious advantages in terms of saving manpower, energy conservation and environmental protection, and construction period. The advantage of the segmented prefabricated integrated pipe gallery is that it reduces the hoisting quality of a single component. However, the positioning and installation during the installation of the segmented prefabricated building structure is more cumbersome than the overall segmented prefabricated installation. The cumbersome positioning and installation leads to low work efficiency. Therefore, fully exploring the rapid positioning and installation technology of the segmented prefabricated structure is of great significance for improving the construction quality of the assembled building structure and enhancing the social benefits.

[0003] At present, the research and application of the segmented prefabricated assembly technology in the field of prefabricated assembly of integrated pipe galleries are relatively few, and the hoisting and positioning methods are relatively primitive. It mainly uses manual assistance or traditional measuring tools for repeated positioning and verification, with quite low efficiency and difficult to control the accuracy. The positioning devices currently in use can solve the plane positioning problem, but it is difficult to solve the problems of verifying the verticality and longitudinal slope of the component while positioning and avoiding the collision of the component with the positioning device during hoisting. Summary of the Invention:

[0004] In view of the above problems, the present invention provides an installation and positioning device for the wall of an assembled integrated pipe gallery that can achieve rapid planar positioning of components and simultaneously quickly verify whether the verticality and longitudinal slope of the component installation meet the requirements, as well as an installation and use method thereof.

[0005] To solve the above problems, the technical solution adopted by the present invention is:

[0006] The present invention provides an installation positioning device for the wall of an assembled integrated pipe gallery. The device includes a starting scale, an ending scale, a calibration rope, a laser level, and a scale sleeve. The starting scale and the ending scale are symmetrically and parallelly arranged on both sides of the precast wall and vertically arranged on the installation base surface. The starting scale consists of a base, a starting scale rod, elevation adjustment bolts, a horizontal scale, a vertical scale, and a footweight. The starting scale rod is perpendicularly welded to the base, the elevation adjustment bolts are threadedly connected to the base, the vertical scale and the horizontal scale are placed on the base, and the footweight is installed on the base. The ending scale consists of a base, an ending scale rod, elevation adjustment bolts, a horizontal scale, a vertical scale, and a footweight. The ending scale rod is perpendicularly welded to the base, the elevation adjustment bolts are threadedly connected to the base, the vertical scale and the horizontal scale are placed on the base, and the footweight is installed on the base. The scale sleeve is sleeved at both ends of the calibration rope and also sleeved on the starting scale rod and the ending scale rod. The calibration rope includes a first calibration rope and a second calibration rope. The two calibration ropes pass through the small holes at the scale positions of the starting scale rod and end at the corresponding small holes at the scale positions of the ending scale rod. The laser level is placed on the starting scale rod.

[0007] The footweight of the starting scale is 3, and the elevation adjustment bolts are 3. The specification of the elevation adjustment bolts is M12*120. The footweight of the ending scale is 3, and the elevation adjustment bolts are 3. The specification of the elevation adjustment bolts is M12*120.

[0008] The scale sleeve is made of flexible plastic.

[0009] The length of the scale sleeve is the distance from the scale rod positioning point to the precast wall installation point.

[0010] The first calibration rope and the second calibration rope are made of strong elastic rubber ropes.

[0011] The first calibration rope passes through the small hole at the 0.5m scale position of the starting scale rod and ends at the small hole at the 0.5m scale position of the ending scale rod. The second calibration rope passes through the small hole at the 1.5m scale position of the starting scale rod and ends at the small hole at the 1.5m scale position of the ending scale rod.

[0012] The laser of the laser level passes through the small hole at the 1.0m scale position of the starting scale rod and projects onto the ending scale rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The device of the present invention is used for quickly positioning the plane during the installation of wall-type precast components under certain longitudinal slope conditions. While achieving the quick plane positioning of wall-type precast components, it can also quickly verify whether the verticality and longitudinal slope of the component installation meet the requirements, greatly improving the installation efficiency of the assembled integrated pipe gallery wall.

DETAILED DESCRIPTION OF THE EMBODIMENTS:

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] See Figures 1-3, the present invention provides an assembly-type integrated pipe gallery wall installation positioning device, which includes a starting scale, an ending scale, a calibration rope, a laser level 3, and a scale sleeve 6. The starting scale and the ending scale are symmetrically and parallelly arranged on both sides of the precast wall 11 and vertically arranged on the installation base surface. The starting scale is composed of a base, a starting scale rod 1, three elevation adjustment bolts 10 of M12*120, a transverse level 9, a longitudinal level 7, and three footweight counterweights 8; the starting scale rod 1 is vertically welded to the base, and the elevation adjustment bolt 10 is threadedly connected to the base for adjusting the base level; the longitudinal level 7 and the transverse level 9 are placed on the base for calibrating the base level; the footweight counterweight 8 is installed on the base to prevent the displacement of the starting scale rod 1. The ending scale is composed of a base, an ending scale rod 2, three elevation adjustment bolts 10 of M12*120, a transverse level 9, a longitudinal level 7, and three footweight counterweights 8; the ending scale rod 2 is vertically welded to the base, and the elevation adjustment bolt 10 is threadedly connected to the base for adjusting the base level and the scale height; the longitudinal level 7 and the transverse level 9 are placed on the base for calibrating the base level; the footweight counterweight 8 is installed on the base to prevent the displacement of the ending scale rod 2. The scale sleeve 6 is made of flexible plastic and is sleeved on both ends of the calibration rope and on the starting scale rod 1 and the ending scale rod 2, and its length is the distance from the scale rod positioning point to the installation point of the precast wall 11. The calibration rope is made of a strong elastic rubber band and includes a first calibration rope 4 and a second calibration rope 5; the two calibration ropes respectively pass through the small holes at the 0.5m and 1.5m scale positions of the starting scale rod 1 and end at the small holes at the 0.5m and 1.5m scale positions of the ending scale rod 2. The laser level 3 is placed on the starting scale rod 1, and the laser passes through the small hole at the 1.0m scale position of the starting scale rod 1 and projects onto the ending scale rod 2.

[0025] Installation steps of the quick positioning device:

[0026] If the length of the precast wall 11 is 570 cm and the height is 400 cm, the sectional control length for the installation of the precast wall 11 is 600 cm, and the longitudinal slope of the precast wall 11 is 0.3%. The quick positioning device is used to achieve quick and efficient positioning.

[0027] A. Preparation for setting out lines before hoisting: Set out lines on the base surface according to the design drawings, use a chalk line to mark the side lines and sectional control lines of the precast wall 11, and use a chalk line to draw a line at a position 0.5 m above the bottom surface of the precast wall 11, which is used as the longitudinal slope calibration line during installation.

[0028] B. Installation of starting scale: Install the starting scale at the starting control point on the base surface, which is the intersection of the side line and the sectional control line. Install the base, starting scale rod 1, elevation adjustment bolt 10, longitudinal level 7, transverse level 9, and foot pressure weight 8 respectively. Adjust the elevation adjustment bolt 10 to make the base under the starting scale rod 1 level. The longitudinal level 7 and the transverse level 9 are used as the calibration standards for whether the base is level.

[0029] C. Installation of ending scale: Install the ending scale at the ending control point on the base surface, which is the intersection of the side line and the sectional control line. Install the base, ending scale rod 2, elevation adjustment bolt 10, longitudinal level 7, transverse level 9, and foot pressure weight 8 respectively. Adjust the elevation adjustment bolt 10 to make the base under the ending scale rod 2 level. The longitudinal level 7 and the transverse level 9 are used as the calibration standards for whether the base is level.

[0030] D. Selection of scale sleeve 6: Since the distance between the scale rods = sectional control length, the length of the scale sleeve 6 is half of the sectional control length minus the length of the precast wall 11. In this embodiment, since the precast wall 11 is 570 cm long and the distance between the scale rods = sectional control length = 600 cm, the length of the scale sleeve 6 is 15 cm.

[0031] E. Installation of calibration ropes: Put 2 scale sleeves 6 on the first calibration rope 4 and the second calibration rope 5 respectively. The two ends of the first calibration rope 4 pass through the small holes at the 0.5 m high positions on the starting scale rod 1 and the ending scale rod 2 respectively, and are fixed on the two scale rods; the two ends of the second calibration rope 5 pass through the small holes at the 1.5 m high positions on the starting scale rod 1 and the ending scale rod 2 respectively, and are fixed on the two scale rods.

[0032] F. Lifting and positioning of precast wall 11: After making the above preparations, the lifting of the precast wall 11 can be started. This device uses the calibration ropes for the horizontal transverse positioning of the precast wall 11, and the flexible scale sleeves 6 at both ends of the calibration ropes for the horizontal longitudinal positioning; the vertical plane formed by the two calibration ropes is used as the calibration plane for whether the precast wall 11 is plumb; whether the calibration rope 4 is parallel to the ink line on the precast wall 11 is used to calibrate the longitudinal slope of the installation of the precast wall 11.

[0033] The use of this quick positioning device, the specific positioning, calibration, and adjustment methods are as follows:

[0034] 1. Planar positioning of precast wall 11: Before installing the precast wall 11, draw the outline of the precast wall 11 and the sectional control line of the pipe gallery on the base surface. The starting scale rod 1 and the ending scale rod 2 are erected at the intersection of the outline of the precast wall 11 and the sectional control line. Use the calibration rope between the starting scale rod 1 and the ending scale rod 2 as the planar lateral positioning device, and use the flexible scale sleeve 6 on the calibration rope as the planar longitudinal positioning device for the precast wall 11. The length of the scale sleeve 6 is the distance between the sectional control line and the precast wall 11. Both the longitudinal and lateral devices use flexible devices to prevent the standard position from shifting due to collision during hoisting.

[0035] 2. Longitudinal slope calibration: Before hoisting the precast wall 11, draw a straight line at a position 0.5 m above the bottom of the precast wall 11. When hoisted in place, if this line is parallel to the first calibration rope 4 at a height of 0.5 m between the scale rods, the longitudinal slope meets the requirement. If the two lines intersect, the installation needs to be readjusted.

[0036] 3. Verticality calibration: When the precast wall 11 is hoisted in place, both the first calibration rope 4 at a position of 0.5 m between the scale rods and the second calibration rope 5 at a position of 1.5 m are closely attached to the precast wall 11. If the distances between the two calibration ropes and the precast wall 11 are inconsistent, it means that the precast wall 11 is not installed vertically and needs to be adjusted.

[0037] 4. Longitudinal slope adjustment: If the required installation longitudinal slope is 0.3%, and the distance between the starting scale rod 1 and the ending scale rod 2 is 6 m, according to the calculation, the calibration rope hole position of the ending scale rod 2 should be 1.8 cm higher than the corresponding calibration rope hole position of the starting scale rod 1. At this time, adjust the elevation adjustment bolt 10 on the base under the ending scale rod 2 so that the horizontal laser projected from the 1.0 m position on the starting scale rod 1 is at the 0.982 m position on the ending scale rod 2.
