[0002] With the development of the national infrastructure field, more and more subways, underground ramps and other buildings will appear. These buildings usually need to install formwork on the inner side of the two outer walls, and then reinforce the formwork to ensure that the building does not collapse; the traditional reinforcement method adopts single-sided formwork, that is, the two formworks are reinforced separately. The single-sided formwork consists of two parts: an embedded system and a frame. The core components include anchor bolts, connecting nuts, external connecting rods, single-sided brackets, external nuts and pressure beams, etc. The process flow can be summarized as: pre-embedded anchor bolts → steel bar binding → external wall formwork → single-sided bracket hoisting → installation of single-sided brackets → installation of reinforced steel pipes → installation of pressure beam channel steel and more than 10 processes; the hoisting of the single-sided formwork usually requires continuous use of a crane of at least 80t + forklift in conjunction with manual installation, and because the single-sided formwork only supports one side, the structural stability is relatively poor, the investment cost is high, and the construction hoisting volume is large; therefore, we propose a formwork reinforcement bracket and its construction method to solve the above problems. Summary of the invention

[0012] A further improvement of the template reinforcement bracket of the present invention is that each of the support plates includes a positioning plate connected to the corresponding telescopic device, a folding plate foldably connected to the top of the positioning plate, and a stopper fixed to the top of the positioning plate and used to support the folding plate in a vertical state to prevent the folding plate from folding inwards;

[0013] When the folding plate is in a vertical state, the side of the folding plate facing the template is flush with the side of the positioning plate facing the template.

DETAILED DESCRIPTION

[0029] In order to solve the problem of poor stability of the single-sided formwork structure, the present invention provides a formwork reinforcement bracket and a construction method thereof. The formwork reinforcement bracket and the construction method thereof are further described below with reference to specific embodiments and accompanying drawings.

[0030] See also Figure 1 to Figure 3 As shown, a template reinforcement bracket is used to simultaneously reinforce two templates 4 installed on the inner sides of two opposite exterior walls 3, and the template reinforcement bracket includes:

[0031] The base 1 is located between the two templates 4 and is connected and anchored to the bottom plate 2 through the embedded parts 9;

[0032] Two first supporting mechanisms are respectively arranged on both sides of the base 1 facing the two templates 4, and are used to support between the base 1 and the two templates 4 respectively. The first supporting mechanism includes a telescopic device fixed to the base 1 and a support plate 5 fixed to the telescopic device and used to abut against the template 4 under the drive of the telescopic device; and

[0033] The two fixing components 6 are used to connect and fix the two support plates 5 to the corresponding templates 4 respectively.

[0034] By starting the telescopic device to drive the support plates 5 at both ends to move toward the two opposite exterior walls 3 and abut against the formwork 4 installed on the exterior walls 3, and then connecting and fixing the formwork 4 and the support plates 5 through the fixing components 6, the double-sided formwork and reinforcement can be completed at the same time, making the structure stable, the operation simple and convenient, the cost low, and the construction hoisting amount small.

[0035] Among them, see Figure 2 As shown, a support frame is fixed on the side of the support plate 5 facing the telescopic device, and the lower part of the support frame is fixed to the telescopic device.

[0036] The supporting frame is driven by the telescopic device to reinforce the corresponding support plate 5 , so as to achieve the first reinforcement of the support plate 5 .

[0037] Among them, see Figure 2 As shown, the template reinforcement bracket also includes a second support mechanism 8, and the second support mechanism 8 includes a telescopic rod telescopically connected between the upper parts of the two support frames;

[0038] The telescopic rod includes a sleeve 802 in the middle and two sleeve rods 803 which are respectively inserted into the two ends of the sleeve 802 and are adjustable in depth. A bracket 801 is connected between the bottom of the sleeve 802 and the top of the base 1.

[0039] For details, see Figure 3 As shown, the telescopic rod also includes two fastening components for fixing the two sleeve rods 803 to the sleeve 802 respectively, and the fastening components include a first bolt 804 and a first screw hole 805 opened on the sleeve 802. The first bolt 804 passes through the first screw hole 805 and is tightly pressed against the sleeve rod 803 to fix the sleeve rod 803 to the sleeve 802;

[0040] In this embodiment, the bracket 801 includes two support rods, the first ends of the two support rods are connected to the bottom of the sleeve 802, and the second ends are connected to the top of the base 1, for supporting the sleeve 802; in another embodiment, the lengths of the two support rods are adjustable to control the height of the sleeve 802 for easy storage and transportation.

[0041] By matching the sleeve 802 with the sleeve rod 803, the two support frames can be supported to reinforce the support plates 5 on both sides. By raising the position of the sleeve 802 to the upper part of the support frame through the bracket 801, the support plate 5 can be supported together with the telescopic member 11 arranged at the lower end, and the supporting force is evenly distributed, so that the support reinforcement effect is better; by tightening the first bolt 804 and the sleeve rod 803, the connection between the sleeve rod 803 and the sleeve 802 can be made more firm, thereby improving the support effect; conversely, by loosening the first bolt 804, the depth of the sleeve rod 803 at both ends inserted into the sleeve 802 can be adjusted, which is convenient for the telescopic member 11 to adjust the distance between the two relative support frames and drive the sleeve rod 803 to adjust, so that the template reinforcement bracket can be applied to two relative exterior walls 3 with different distances;

[0042] Further, see Figure 3 As shown, a partition plate 806 is fixed to the end of one end of the sleeve rod 803 inserted into the sleeve 802. The size of the partition plate 806 is adapted to the interior of the sleeve 802. In actual application, the partition plate 806 can prevent the sleeve rod 803 from escaping from the sleeve 802, thereby playing a limiting effect.

[0043] Among them, see Figure 2 As shown, each telescopic device includes two telescopic parts 11 spaced apart along a direction perpendicular to the telescopic direction, each supporting frame includes two vertical rods 7, the number of telescopic rods in the second supporting mechanism 8 is two, and the two vertical rods 7 of each supporting frame are connected one by one to the ends of the two telescopic parts 11 of the corresponding telescopic device, and the vertical rods 7 of the two supporting frames are opposite to each other and are respectively connected to the two ends of the two telescopic rods.

[0044] Specifically, the telescopic member 11 may be a hydraulic telescopic rod; by arranging the telescopic members 11 at intervals, the force balance of supporting the vertical rod 7 may be improved.

[0045] Among them, see Figure 2 As shown, each support plate 5 includes a positioning plate 501 connected to the corresponding telescopic device, a folding plate 502 foldably connected to the top of the positioning plate 501, and a stopper 503 fixed to the top of the positioning plate 501 and used to support the folding plate 502 in a vertical state to prevent the folding plate 502 from folding inwards;

[0046] When the folding plate 502 is in a vertical state, the side of the folding plate 502 facing the template 4 is flush with the side of the positioning plate 501 facing the template 4 .

[0047] By designing the support plate 5 to be foldable, it is convenient for storage and transportation when not in use;

[0048] Further, see Figure 1 As shown, each fixing assembly 6 includes a second bolt, a second screw hole 601 passing through the folding plate 502 and the positioning plate 501, and a third screw hole opened on the side of the template 4 facing the support plate 5. The second bolt passes through the second screw hole 601 and is inserted into the third screw hole to connect and fix the support plate 5 to the corresponding template 4; the number of the second bolt, the second screw hole 601 and the third screw hole can be set according to actual applications.

[0049] The embedded part 9 includes a plurality of through slots 904 penetrating the base 1 and a plurality of position-limiting embedded parts 902 correspondingly arranged in the plurality of through slots 904 and anchored in the bottom plate 2;

[0050] A plurality of through grooves 904 are arranged at intervals on the base 1 and are divided into two through groove groups along the center line of the base 1. A plurality of limiting embedded parts 902 are divided into two limiting embedded parts groups corresponding to the two through groove groups. The formwork reinforcement bracket also includes two diagonal brace groups corresponding to the two limiting embedded parts groups, which are used to respectively support between the base 1 and the two support plates 5. Each diagonal brace group includes a plurality of diagonal braces 10 corresponding to the number of limiting embedded parts 902 in the corresponding limiting embedded parts group, and one end of each diagonal brace 10 is against the corresponding support plate 5, and the other end is against the corresponding limiting embedded part 902.

[0051] Specifically, the embedded part 9 also includes two hollow cone groups arranged at the bottom of the base 1 and corresponding to the two through-slot groups respectively. A filling slot 903 connected to all the through-slots 904 is opened on the top of the base 1. The end of the limiting embedded part 902 away from the bottom plate 2 extends out of the filling slot 903 and abuts against the diagonal brace 10. The design of the embedded part 9 can strengthen the base 1 and better grip the bottom plate 2, providing the basis of the support system. The limiting embedded part 902 can be a steel bar. By setting a certain number of diagonal braces 10, three reinforcements of the two support plates 5 can be achieved, greatly improving the support effect.

[0052] Furthermore, a positioning piece is provided at the end of the diagonal brace 10 , and a fourth screw hole is penetrated through the positioning piece. The second bolt passes through the fourth screw hole, the second screw hole and is inserted into the third screw hole in sequence to fix the support plate 5 and the diagonal brace 10 .

[0053] A construction method for a template reinforcement bracket comprises the following steps:

[0054] Providing a formwork reinforcement bracket as described above;

[0055] First, place the base 1 on the top of the concrete poured to form the bottom plate 2, then pass the first end of the limiting embedded part 902 through the filling groove 903, and respectively through the corresponding through grooves 904 and directly insert into the concrete, and extend the second end of the filling groove 903 to the top of the base 1, wait for the bottom plate 2 to solidify, and then connect and anchor the base 1 to the bottom plate 2;

[0056] The telescopic members 11 at both ends are activated to drive the two support plates 5 to move toward the templates 4 installed on the two opposite exterior walls 3 and to abut against the templates 4. During the process, the sleeve rods 803 at both ends are pulled to extend outwards.

[0057] Screw the first bolt 804 through the first screw hole 805 and tighten it against the sleeve rod 803 to fix the sleeve 802 and the sleeve rod 803;

[0058] Provide an oblique support 10, and place the positioning piece on the oblique support 10 against the support plate 5 so that the fourth screw hole corresponds to the second screw hole, and the other end of the oblique support 10 is tightly pressed against the second end of the limiting embedded part 902;

[0059] Then, the second bolt is passed through the fourth screw hole and the second screw hole 601 in sequence and inserted into the third screw hole to fix the support plate 5 to the template 4 and the diagonal brace 10 to the support plate 5 .

[0060] The embedded part 9 includes a plurality of through slots 904 and a plurality of position-limiting embedded parts 902;

[0061] After pouring the concrete of the bottom plate 2 and before the concrete solidifies, the base 1 is first placed on the top of the concrete, and then a plurality of limiting embedded parts 902 are respectively passed through a plurality of through grooves 904 and directly inserted into the concrete, so that the plurality of limiting embedded parts 902 are anchored in the concrete as the concrete solidifies, so as to realize the connection and anchoring of the base 1 with the bottom plate 2 through the embedded parts 9.
