Description

TECHNICAL FIELD

[0001] The present application relates to the field of building construction, in particular to a prefabricated wall column connecting and supporting device and a supporting method. BACKGROUND

[0002] At present, in the application of wall column pouring formwork, wall penetrating screws and back lath are generally used to reinforce the formwork. This method is prone to leave screws in the wall, and the screws left in the wall need to be removed by mechanical cutting in the later stage.

[0003] To solve the above problems, Chinese patent CN112127621A discloses a wall column formwork, which comprises two oppositely arranged formwork pieces and a connecting piece connecting the two formwork pieces. The formwork piece is formed by splicing a plurality of formworks. The wall column formwork further comprises: a first fastener fixed to the formwork piece; a second fastener fixed to the first fastener, and the second fastener is arranged at the splicing position between the plurality of formworks; a support assembly comprising a support and a tensioning member, the support has two ends fixed to the formwork piece and the ground, and the tensioning member has one end fixed to the formwork piece and the other end fixed to the support at the position where the support contacts the ground. The first fastener and the second fastener are arranged on the formwork piece in a cross manner, and the second fastener is arranged at the splicing seam position of the formwork piece to increase the stability of the formwork piece. The present application provides a support force outward and a tensioning force inward to the formwork piece through the support and the tensioning member arranged on the formwork piece, thereby further improving the stability of the formwork piece. Moreover, the formwork piece is connected, fixed and supported by the detachable device without penetrating the wall, so that the connecting piece will not be left in the wall.

[0004] The above device has the following problems: 1. A large number of various fastening devices are used to complete the installation through complicated installation steps, which is very time-consuming for construction projects that need to be completed on schedule; 2. In the actual construction process, the first fasteners of the formwork have no connection relationship between the upper and lower first fasteners, and can only be aligned by visual inspection. However, the alignment by visual inspection will deviate, which will cause the second fasteners to not be easily connected to the upper and lower first fasteners. Moreover, the higher the height of the wall column, the more formworks are needed, the more first fasteners are needed, and the more times the alignment by visual inspection is needed, which will cause the accumulation of deviation and further cause the problem that the second fasteners cannot be easily connected to the upper and lower first fasteners. SUMMARY

[0005] The present application provides a prefabricated wall column connecting and supporting device to solve the problem of complicated installation steps of the existing wall column formwork prefabricated wall column connecting and supporting device.

[0006] In order to achieve the above object, the present application adopts the following technical scheme: A prefabricated wall column connecting support device, comprising a support assembly and two oppositely arranged formwork pieces, the formwork piece comprises a plurality of vertically arranged formworks, the support assembly comprises a support piece and a tensioning piece, one end of the support piece is fixed to the formwork piece, the other end of the support piece is fixed to the ground, one end of the tensioning piece is fixed to the formwork piece at a position higher than the support piece, the other end of the tensioning piece is fixed to the position where the support piece contacts the ground, and the connecting support device further comprises a plurality of connecting support devices, the connecting support device comprises a first module and a second module, the first module is detachably connected with the formwork, one end of the first module is provided with a first groove, the other end of the first module is fixedly connected with the second module, and the second module can be slidably connected with the first groove.

[0007] The principle and advantages of the present application are as follows:

[0008] 1. The prior art needs to fix the first fastener on the formwork with a fixing buckle, and the multiple first fasteners in the vertical direction need to be manually aligned, and then the second fastener is passed through the multiple first fasteners. In this process, a large number of fixing buckles and first fasteners need to be installed on the formwork, and the multiple fixing buckles and first fasteners need to be aligned for the installation of the second fastener. This process is complicated and time-consuming. Compared with the prior art, the present application fixes the first module on the formwork, and then the second module on the formwork is inserted into the first groove on the adjacent formwork to connect the adjacent two formworks. By inserting the second module into the first groove, the following effects can be achieved: (1) the alignment of the adjacent two connecting support devices in the vertical direction; (2) the tightening effect on the adjacent two formworks, preventing the sliding between the adjacent two formworks; (3) the supporting effect on the adjacent two formworks, improving the structural stability and avoiding the bending of the formwork. The present application eliminates the manual alignment step and the separate tightening step of the prior art, making the operation more convenient and saving time.

[0009] 2. The multiple components used in the prior art have no connection relationship before installation, and need to be stored separately, which makes it more troublesome to store and more likely to lose parts in actual construction. The connecting support device of the present application is integrated and does not need to be stored separately, which is convenient to store and not easy to lose.

[0010] Preferably, as an improvement, a first circular hole is provided on the side wall of the first module, which is in communication with the first groove, and a knob column is further provided, which is threadedly connected with the first circular hole. After the knob column is screwed into the first circular hole, it will abut against the second block of the other connecting support device, increasing the stability of the connection between the two connecting support devices, and further increasing the stability of the connection between the upper and lower formworks.

[0011] Preferably, as an improvement, the knob column is provided with a handle.

[0012] Preferably, as an improvement, the second module is provided with a second circular hole capable of being screwed with the knob column. After the knob is screwed with the first circular hole and the second circular hole, the rotation of the knob column is limited to restrict the relative movement of the upper and lower connecting support devices, thereby increasing the stability of the connection between the upper and lower connecting support devices, and further increasing the stability of the connection between the upper and lower formworks.

[0013] Preferably, as an improvement, it further includes a steel wire rope, which connects the knob columns at the same height on both sides of the wall column. The use of the steel wire rope to connect the formworks on both sides of the wall column increases the stability between the formwork pieces on both sides of the wall column.

[0014] Preferably, as an improvement, the knob column is provided with a first rope hole and a second rope hole, and the steel wire rope has two ends, one end of which is connected to the first rope hole on one side of the wall column, and the other end of which is connected to the second rope hole on the other side of the wall column. The first rope hole and the second rope hole on the knob column are connected to the knob columns on both sides of the wall column, which generates a support force from the outside to the inside on the formwork pieces on both sides of the wall column. By rotating the knob column, the steel wire rope is wound and contracted on the knob column, further increasing the support force of the steel wire rope on the formwork pieces on both sides of the wall column, and further increasing the stability of the connection between the formwork pieces on both sides of the wall column.

[0015] Preferably, as an improvement, it further includes a first extension unit, which includes four extension blocks fixedly connected with the first module, two of which are located on both sides of the first module close to the first groove, and the other two of which are located on both sides of the first module close to the second module. The existing bolts are used to connect the adjacent extension blocks of the adjacent two first modules in the vertical direction, thereby increasing the fastening of the connection between the adjacent two first modules, and further increasing the fastening of the connection between the adjacent two formworks.

[0016] Preferably, as an improvement, it further includes a second extension unit, which includes two extension sheets, one on each side of the first module. The existing bolts are used to connect the two extension sheets with the formwork, thereby fixing the first module on the formwork, and further increasing the fastening of the connection between the first module and the formwork.

[0017] The present application provides a support method based on the connecting support device, which is used to support the entire wall column formwork, and solves the problem of fixing the formwork pieces in a more convenient way.

[0018] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a support method of an assembled wall column connecting support device, comprising the following steps:

[0019] Step (1): connect the extension piece to the template using existing bolts, so that the first module is connected to the template;

[0020] Step (2): extend the second module on the template into the first groove on the adjacent template, so that the first circular hole coincides with the second circular hole;

[0021] Step (3): screw the knob column into the first circular hole and the second circular hole;

[0022] Step (4): connect the adjacent extension blocks of the two adjacent first modules using existing bolts;

[0023] Step (5): connect the first rope holes on both sides of the wall column at the same height with a steel wire rope, connect the second rope holes on both sides of the wall column at the same height with another steel wire rope, and rotate the knob column so that the steel wire ropes are wound and tightened on the knob column;

[0024] Step (6): fix one end of the support member to the template member, fix the other end of the support member to the ground, fix one end of the tensioning member to the template member at a position higher than the support member, and fix the other end of the tensioning member to the support member at a position in contact with the ground.

[0025] The principle and advantages of the present scheme are: the support method utilizes the connection support device and the support assembly to greatly stabilize the overall structure of the wall column template; the present scheme eliminates the steps of manual alignment and separate operation for tightening in the prior art, making the operation more simple and saving time.
