A kind of building unit with preventing sagging device
Technical field
the present invention relates to a kind of building unit with preventing sagging device.
Background technology
the construction method of building unit is that sling four angles of building unit are moved and installed, in prior art, in the time slinging four angles, for fear of building unit particularly long side direction produce harmful sagging distortion and take following several countermeasure: 1. use larger bottom girder and the back timber in cross section: in the time that the long limit of cell cube is larger, while reaching the span of 40ft such as size, because needs use heavy in section beam, can make thus ceiling step-down; 2. adopt the unit (such as 20ft) of short and small span: can produce obstacle to forming large space and cost by little cell formation building; 3. the wall that increases unit is with the intensity of enhancement unit: for example container adopts the steel plate sidewall of notch cuttype, or carry out the intensity of enhancement unit by increasing braced structures etc., but the drawback causing is thus that large-scale window can not be installed, and be difficult to form continuous room by building unit side by side.For above problem, " with the building unit of sagging prevention device " (patent No.: 201110358967.3 201120448365.2) provided solution, can effectively guarantee the stability of building unit structure in whole transportation.
but also some worth improved place of former design:
1, need to, on the girder of the bottom of building unit, open the hole that 4 diameters are 92 millimeter, do so on the one hand, the amount of machining increases, and takes time and effort; Reduce on the other hand the intensity of bottom girder; On the one hand due to perforate on finished section bar, the preservative treatment of metal requires to promote again.
, each building unit needs the steel pipe that two diameters are 89 millimeter, 2.5 meters of left and right of length (hanging rod) in " with the building unit of sagging prevention device " as assistant conveyance instrument, do so on the one hand because the increase of steel can make expense increase.In transportation, to allow on the other hand steel pipe pass through the width of whole building unit, the building layout of bottom be limited to, then can destroy original attemperator on the one hand.
, intrinsic eccentric nut design, on the one hand offset only has 3 millimeters, adjustable amount is little; Due to structure, in assembling situation, implement to regulate very difficult on the other hand; Cannot self-locking after regulating on the one hand again.
Summary of the invention
the object of the invention is to provide a kind of building unit with preventing sagging device, can continue to keep former patent advantage, effectively guarantee the stability of building unit structure in whole transportation, effectively overcome above-mentioned three problem points, make former scheme more perfect simultaneously.
in order to reach above object, the technical solution used in the present invention is: a kind of building unit with preventing sagging device, it comprises supporting construction and the structural long limit of mounting support face, supporting construction comprises the pillar of vertical setting, the back timber that is horizontally disposed with and is connected with the upper end of pillar, the bottom girder that parallels with the length direction of back timber and be connected with the lower end of pillar, the gripper shoe that pillar and bottom girder are obliquely installed relatively, the upper end of gripper shoe and the top of pillar are fixedly connected, the lower end of gripper shoe is connected with the middle part of bottom girder, and the junction of gripper shoe and bottom girder is between the junction of pillar and bottom girder and the mid point of bottom girder, on bottom girder, be fixedly connected with a fixed cover, in gripper shoe, be connected with rotationally an adjusting sleeve, rotating shaft between the two is the first axle, adjusting sleeve is connected rotationally with fixed cover, rotating shaft between the two is the second axle, and the first axle parallels with the second axle and not on same straight line.
further, offer adjustment hole in adjusting sleeve, this adjustment hole is connected separatably with a regulating rod.
further, adjusting sleeve and fixed cover socket-connect, and offer stopper slot in adjusting sleeve, and this stopper slot is the circumference setting along adjusting sleeve around the second axle, and on fixed cover, tool is there being the limited block being movably located in stopper slot.
preferably, adjusting sleeve comprise with gripper shoe rotate the first noumenon that is connected and with rotate the second body of socket of fixed cover, adjustment hole is opened on the first noumenon, stopper slot is opened on the second body.
more preferably, regulating sleeve is rotated and is connected by trip bolt with gripper shoe.
owing to having adopted technique scheme, a kind of building unit with preventing sagging device of the present invention, replace eccentric nut with the fixed cover matching and adjusting sleeve, when adjusting, in the adjustment hole of adjusting sleeve, insert regulating rod, rotation adjusting sleeve to correct position, utilize in adjusting sleeve compared with large eccentricity distance, gripper shoe is strained.Without perforate on bottom girder, omitted and hung rod, and regulated quantity increases.

The specific embodiment
below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
referring to accompanying drawing 1 to accompanying drawing 4, a kind of building unit with preventing sagging device in the present embodiment, it comprises supporting construction and the structural long limit of mounting support face, supporting construction comprises the pillar 1 of vertical setting, the back timber 2 that is horizontally disposed with and is connected with the upper end of pillar 1, the bottom girder 3 that parallels with the length direction of back timber 2 and be connected with the lower end of pillar 1, the gripper shoe 4 that pillar 1 and bottom girder 3 are obliquely installed relatively, the top of the upper end of gripper shoe 4 and pillar 1 is fixedly connected, the lower end of gripper shoe 4 is connected with the middle part of bottom girder 3, and the junction of gripper shoe 4 and bottom girder 3 is between the junction of pillar 1 and bottom girder 3 and the mid point of bottom girder 3, on bottom girder 3, be fixedly connected with a fixed cover 5, in gripper shoe 4, be connected with rotationally an adjusting sleeve 6, rotating shaft between the two is the first axle, adjusting sleeve 6 is connected rotationally with fixed cover 5, rotating shaft between the two is the second axle, and the first axle parallels with the second axle and not on same straight line.
as shown in accompanying drawing 4 and accompanying drawing 5, adjusting sleeve 6 comprise with gripper shoe 4 rotate the first noumenon 61 that is connected and with rotate the second body 62 of socket of fixed cover 5.
the first noumenon 61 is a circular flat board, and the one side of this flat board is fixedly connected with one end of the second body 62, and another side contacts with gripper shoe 4.In the present embodiment, the first noumenon 61 is rotated and is connected by trip bolt 65 with gripper shoe 4, and the axial line of trip bolt 65 is the second axle.On the sidewall of the first noumenon 62, offer adjustment hole 63, this adjustment hole 63 is connected separatably with a regulating rod.
