Technical Field

[0001] The utility model belongs to the technical field of construction formwork, and in particular relates to a single-side formwork and a supporting system for a wall. Background Art

[0002] Single-sided formwork is required in the construction of retaining walls, basement exterior walls, etc. The most common single-sided formwork is a triangular structure, with the vertical part used as formwork support, the horizontal part used as ground fixation, and the oblique part used as support and reinforcement between the two. Before pouring the formwork, the single-sided formwork needs to be fixed and installed in groups. After pouring, it will be dismantled for storage.

[0003] However, this single-sided formwork not only occupies a large ground space when stored, but is also inconvenient to carry because of the large size of the horizontal portion. Utility Model Content

[0004] The utility model aims to provide a single-sided formwork and support system for a wall, which can reduce the space occupied during storage through a variable-form installation method and is also more convenient for transportation.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a single-sided formwork for a wall, comprising:

[0006] A column, wherein a rotatable hook is installed in the middle part of the column;

[0007] A crossbar, the inner end of which is hingedly connected to the bottom end of the column;

[0008] An oblique rod, the bottom end of which is hingedly connected to the outer end of the cross rod, the top end of which is provided with a snap-fitting page, so that when the end abuts against the inner side of the column, it is snap-fitted and fixed by the snap hook, and the middle part of which is provided with a rotatable connecting rod clamp seat;

[0009] When the single-sided wall formwork is in use, the cross bar and the column are in a mutually perpendicular state, and the top end of the oblique bar can abut against the inner side of the column so that the hook can clamp and fix the hinge plate of the engaging leaf;

[0010] When the single-sided formwork of the wall is in a retracted state, the cross bar and the diagonal bar are both against the inner side of the column, and the connecting rod clamp seat can rotate toward one side of the column and be fixed to the column by a pin shaft.

[0011] Furthermore, the upright posts, cross bars and diagonal bars are rod-shaped components with the same structure but different lengths, and have cavities capable of accommodating the hooks or connecting rod clamp seats.

[0012] Furthermore, the uprights, cross bars and diagonal bars all include channel steel members spaced apart and arranged back to back, and fixing plates fixed at the ends of the channel steel members.

[0013] Furthermore, bolts are connected between the channel steel parts.

[0014] Furthermore, the connecting rod clamp seat can be selectively pin-connected and fixed with the diagonal rod and the column through a pin shaft.

[0015] Furthermore, it also includes:

[0016] A towing rod, the inner end of which is hingedly connected to the top end of the column;

[0017] A support rod, the top end of which is hingedly connected to the outer end of the towing rod, and the bottom end of which is selectively pinned and fixed to different pin holes on the column through a pin shaft;

[0018] When the bottom end of the support rod is fixedly connected with the upper pin hole on the column, the towing rod and the column are in a mutually perpendicular state;

[0019] When the bottom end of the support rod is fixedly connected with the lower pin hole on the column, the towing rod and the support rod are both accommodated in the column.

[0020] Furthermore, a limit hook is fixed on the outer end of the tow bar.

[0021] The present invention also provides a support system, comprising a plurality of wall single-sided formworks arranged side by side and fixed by connecting rods, characterized in that the wall single-sided formworks are the above-mentioned wall single-sided formworks.

[0022] Furthermore, it also includes a platform pedal; the single-sided formwork of the wall also includes:

[0023] A towing rod, the inner end of which is hingedly connected to the top end of the column;

[0024] A support rod, the top end of which is hingedly connected to the outer end of the towing rod, and the bottom end of which is selectively pinned and fixed to different pin holes on the column through a pin shaft;

[0025] When the bottom end of the support rod is pinned and fixed to the upper pin hole on the column, the towing rod and the column are in a mutually perpendicular state to support the platform pedal;

[0026] When the bottom end of the support rod is fixedly connected with the lower pin hole on the column, the towing rod and the support rod are both accommodated in the column.

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

[0028] 1) The single-sided support mold in the utility model has two forms. When in use, it can form a single-sided support for the template to meet the requirements of wall casting; when in the storage state, the overall width is greatly reduced to the width of two channel steel parts to reduce space occupancy and facilitate transportation.

DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the utility model are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] Embodiment 1

[0044] like Figures 1 to 9 As shown, this embodiment discloses a single-sided formwork 100 for a wall, including a column 1, a crossbar 2 and an inclined bar 3. In order to facilitate processing and manufacturing, as a preferred example, the column 1, the crossbar 2 and the inclined bar 3 are all rod-shaped components with the same structure but different lengths, and have a cavity capable of accommodating the hook 5 or the connecting rod clamp seat 4. More specifically, the column 1, the crossbar 2 and the inclined bar 3 all include channel steel members spaced apart in a back-to-back manner and a fixing plate fixed to the end of the channel steel member, and the channel steel member is a 14a hot-rolled channel steel with an interval of 40mm-50mm. Bolt assemblies 11 are also connected between the channel steel members to improve the connection strength between the channel steel members to prevent bending and deformation.

[0045] The column 1 is processed with a plurality of through holes, which are distributed in sequence along the length direction. Some of the through holes are used as pin holes to install the pin shaft, and the remaining through holes are used as mounting holes to install the pivot shaft. The pin holes on the column 1 are respectively a support rod fixing pin hole 101 and an inclined rod fixing pin hole 102 from top to bottom. There are two support rod fixing pin holes 101, and they are arranged one above and one below. The number of inclined rod fixing pin holes 102 is determined according to the number of connecting rod clamp seats 4.

[0046] The middle part of the column 1 is provided with a rotatable hook 5, which is installed in one of the through holes via a pivot. Since the two channel steel members of the column 1 are arranged at intervals, the hook 5 is installed in the space formed by the interval, so that it can be rotated in and out. Obviously, the hook 5 is rotated out to achieve the clamping connection, and is rotated in to achieve the storage. The setting position of the hook 5 needs to be determined according to the lengths of the cross bar 2 and the diagonal bar 3.

[0047] The inner end of the cross bar 2 is hingedly connected to the bottom end of the column 1 through a hinge joint 6. Therefore, the cross bar 2 is horizontally placed on the ground to be perpendicular to the column 1 in the use state, and in this state, the cross bar 2 is fixed to the ground by anchor bolts. This fixing method belongs to the prior art, so it is not repeated. When the cross bar 2 is in the retracted state, it can be attached to the side of the column 1 for easy storage.

[0048] The bottom end of the diagonal rod 3 is hingedly connected to the outer end of the cross bar 2 through a hinge joint 6, and a snap joint 7 is installed on the top end thereof, so that the end is snapped and fixed by the hook 5 when it abuts against the inner side of the column 1. Specifically, the hinge plate of the snap joint 7 will abut against the inner side of the column 1 after opening, and the hook 5 will clamp the hinge plate after rotating from top to bottom. The middle part of the diagonal rod 3 is installed with a rotatable connecting rod clamp seat 4, which is installed in the space between the two channel steel parts of the diagonal rod 3 by pivoting. The connecting rod clamp seat 4 rotates outward to achieve the fixation of the connecting rod 200, and rotates inward to achieve the fixation of the column 1. Obviously, a pin can be inserted into the diagonal rod fixing pin hole 102 of the column 1, and the clamping hole of the connecting rod clamp seat 4 is fixed by the pin to achieve the fixed connection between the diagonal rod 3 and the column 1.

[0049] As a preferred example, in order to improve the firmness of the connecting rod clamp seat 4, the connecting rod clamp seat 4 should be fixed on the diagonal rod 3 at a certain angle when fixing the connecting rod 200. Therefore, the connecting rod clamp seat 4 is configured to be selectively pinned and fixed with the diagonal rod 3 and the column 1 through a pin shaft. The connecting rod clamp seat 4 and the diagonal rod 3 are both provided with a clamp seat fixing pin hole 103. When the connecting rod clamp seat 4 is fixed to the connecting rod 200, the two clamp seat fixing pin holes 103 are aligned and the pin shaft is inserted.

[0050] As a preferred example, in some construction situations, it is necessary to set up a top platform to meet the traffic needs, and a supporting component is usually set at the top of the formwork for laying the platform pedal 300. Therefore, the single-sided wall formwork 100 in this example also includes a tow rod 8 and a support rod 9. The inner end of the tow rod 8 is hingedly connected to the top of the column 1. The top of the support rod 9 is hingedly connected to the outer end of the tow rod 8, and its bottom end can be selectively pinned and fixed with different pin holes on the column 1 through a pin shaft. Specifically, when the bottom end of the support rod 9 is pinned and fixed to the upper support rod fixing pin hole 101 on the column 1, the tow rod 8 and the column 1 are in a mutually perpendicular state. When the bottom end of the support rod 9 is pinned and fixed to the lower support rod fixing pin hole 101 on the column 1, the tow rod 8 and the support rod 9 are both accommodated in the column 1.

[0051] As a preferred example, the outer end of the towing rod 8 is fixed with a limit hook 10. After the platform pedal 300 is laid, the outer side of the platform pedal 300 is limited by the template, and the inner side thereof is limited by the limit hook 10, thereby preventing the platform pedal 300 from moving.

[0052] When in use, the cross bar 2 and the column 1 are in a mutually perpendicular state, the top end of the oblique bar 3 abuts against the inner side of the column 1, and the hook 5 is rotated outward to clamp and fix the hinge plate of the engagement page 7.

[0053] When storing, the pins fixing the connecting rod 200 clamp seat 4 and the support rod 9 are pulled out, and then the cross bar 2 and the diagonal bar 3 are both placed against the inner side of the column 1, and then the connecting rod clamp seat 4 flipped into the gap of the column 1 is pinned and fixed with the corresponding pin hole of the column 1 by the pin.

[0054] That is to say, in the use state, Figure 1 and Figure 5 As shown, the overall shape is the same as the single-sided formwork in the prior art, both forming a triangular support. Figure 6 and Figure 8 As shown, the towing rod 8 and the supporting rod 9 are completely stored in the space formed by the interval of the column 1. The crossbar 2 and the diagonal rod 3 are fixed close to the side of the column 1. The overall shape becomes a slender structure, and the horizontal dimension is greatly reduced to twice the width of the channel steel member. Taking the 14a channel steel member used in this example, its width is 140mm. When in use, the horizontal dimension of the single-sided formwork W1≈1301mm, and when in the folded state, the horizontal dimension of the single-sided formwork W2≈280mm. It can be seen that the horizontal dimension is reduced by about 74.5%. At this time, it can be stacked and stored horizontally, which greatly improves the space utilization rate.

[0055] Embodiment 2

[0056] like Fig.10 As shown, the present invention further provides a support system, comprising a plurality of wall single-sided formworks 100 arranged side by side and fixed by connecting rods 200, wherein the wall single-sided formworks 100 are the wall single-sided formworks 100 in the first embodiment.

[0057] When in use, the connecting rod 200 is fixed to the connecting rod clamp seat 4 of each wall single-side formwork 100, so as to achieve the fixation of all wall single-side formworks 100. The other side of the column 1 is connected to the template to form a support.

[0058] As a preferred example, the support system further includes a platform pedal 300. The number of the platform pedals 300 is determined according to the travel distance, and the platform pedals 300 are laid on the towing bar 8 to form a passage.
