Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically a combined template for building engineering cost estimation. Background Technology

[0002] Construction engineering refers to a series of activities, including planning, designing, constructing, installing, and maintaining various buildings and structures, to achieve the construction and use functions of the buildings or structures. It includes various types such as industrial buildings (such as factory buildings and warehouses), civil buildings (such as residences, apartments, shopping malls, schools, and hospitals), public buildings (such as libraries, theaters, and stadiums), and infrastructure buildings (such as bridges, roads, tunnels, and water conservancy facilities). In construction engineering, the first step is to prepare a cost estimate, which involves publicizing the basic data, costs, and other detailed information of the construction engineering cost estimate. To facilitate the publicization of this data, a construction engineering cost estimate template is required.

[0003] A search revealed that Chinese Patent Publication No. CN223386970U discloses a combined template for construction project cost estimation, which relates to the field of construction engineering technology. It aims to solve the technical problem that current combined templates for construction project cost estimation are not convenient for quick replacement. The template includes a fixed support, on which an installation plate is arranged.

[0004] While the above-mentioned technical solutions can achieve the disassembly and replacement of templates, the template disassembly and assembly process relies on the collaborative operation of multiple structures. It is necessary to release the constraints of the quick-fixing components and the synchronous drive mechanism in sequence, which involves multiple steps of manual intervention, resulting in low maintenance efficiency. Furthermore, the rigidly fixed four-template layout cannot be dynamically adjusted according to the project scale. In small-scale repair projects or on-site rapid calculation scenarios, redundant templates occupy valuable operating space. The horizontal expansion characteristics of the overall structure are incompatible with the limited office environment, which is not conducive to temporary arrangement in narrow construction sites and increases storage and transportation costs. Therefore, it is necessary to design a combined template for construction cost estimation to improve the above problems. Utility Model Content

Thus, one, two, three, or four templates can be assembled and used according to usage requirements, avoiding resource waste, improving template utilization, reducing lateral space occupation, and making it suitable for on-site operations or office environments with limited space. It is also convenient to carry to different construction sites or meeting rooms for use. Attached Figure Description

[0046] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0047] Example:

[0048] Please see Figures 1-10 This embodiment provides a construction project cost estimate template, including a first mounting plate 1, a second mounting plate 2, a third mounting plate 3, and a template 4;

[0049] The second mounting plate 2 is disposed on one side of the first mounting plate 1, and the second mounting plate 2 and the first mounting plate 1 are rotatably connected by a hinge. Both the first mounting plate 1 and the second mounting plate 2 have internal receiving cavities 8, with the openings of the receiving cavities 8 on the first mounting plate 1 and the second mounting plate 2 located at opposite ends. Two third mounting plates 3 are disposed, and are slidably installed within the receiving cavities 8 of the first mounting plate 1 and the second mounting plate 2 respectively. Four templates 4 are disposed, and are respectively installed on the front end faces of the first mounting plate 1, the second mounting plate 2, and the two third mounting plates 3. The third mounting plates 3 are slidably installed within the receiving cavities 8 of the first mounting plate 1 and the second mounting plate 2. Inside the cavity 8, the third mounting plate 3 can be stored inside the first mounting plate 1 and the second mounting plate 2. Only the first mounting plate 1 and the second mounting plate 2 are used to install the template 4. The second mounting plate 2 is rotatably connected to the first mounting plate 1, and the second mounting plate 2 can be folded relative to the first mounting plate 1. Only the first mounting plate 1 is used to install the template 4. Thus, one, two, three, or four templates 4 can be assembled and used according to usage needs, avoiding resource waste, improving template utilization, reducing lateral space occupation, and making it suitable for on-site operations or office environments with limited space. It is also convenient to carry to different construction sites or meeting rooms for use.

[0050] As a preferred embodiment of this example, the four templates 4 can be used as different sections of the construction project cost estimate, such as a basic data entry area, a cost calculation area, a result display area, and a related information supplementation area, to realize the modular division of labor in the cost estimate process. Users can quickly locate the operation area and avoid data confusion or repeated filling.

[0051] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, a fixing structure is provided between the template 4 and the first mounting plate 1, the second mounting plate 2, and the two third mounting plates 3. The fixing structure includes positioning posts 401 fixedly connected to the four corners of the back of the template 4, and positioning holes 5 opened on the front surfaces of the first mounting plate 1, the second mounting plate 2, and the two third mounting plates 3, corresponding to the positions of the positioning posts 401. The positioning posts 401 and the template 4 can be fixed with bolts or integrally formed. A locking block 402 is fixedly connected to the bottom of the positioning post 401. A slot 501 is opened at the bottom of the positioning hole 5 for the locking block 402 to be inserted. The slot 501 is adapted to the shape of the locking block 402. The height of the positioning hole 5 is greater than the height of the positioning post 401 and the locking block 402, so that the positioning post 401... Both the template 4 and the locking block 402 can be inserted into the positioning hole 5. When assembling the template 4 with the first mounting plate 1, the second mounting plate 2 and the third mounting plate 3, the positioning pin 401 on the template 4 is aligned and inserted into the positioning hole 5. When the end face of the positioning pin 401 abuts against the inner wall of the positioning hole 5, the assembly is in place. At this time, the template 4 is lowered. Under the action of gravity, the template 4 moves slightly downward, so that the locking block 402 is locked into the slot 501, thereby fixing the position of the template 4. When disassembling and replacing the template 4, the template 4 can be lifted slightly upward to disengage the locking block 402 from the slot 501. Then the template 4 can be moved horizontally to disassemble and remove the template 4, making the replacement of the template 4 convenient and quick, and improving its practicality.

[0052] In this embodiment, as Figure 2 and Figure 6 As shown, the construction project cost estimate template also includes a first locking component 6, which is installed on the first mounting plate 1. The first locking component 6 is used to lock the second mounting plate 2 in the unfolded and folded positions.

[0053] The first locking assembly 6 includes a fixed frame 601, a first moving rod 602, a sliding plate 603, a first spring 604, and a connecting plate 605. A groove is formed on the top of the first mounting plate 1. The fixed frame 601 has an inverted U-shaped structure and is fixedly connected to the inside of the groove by bolts. The first moving rod 602 is vertically positioned and slidably passes through the fixed frame 601. A first through hole is formed on the fixed frame 601, through which the first moving rod 602 slidably passes. The sliding plate 603 is slidably connected to the fixed frame 601. Inside, the bottom end of the first moving rod 602 is fixedly connected to the sliding plate 603. The first moving rod 602 and the sliding plate 603 can be fixed by bolts, welding, etc. The first spring 604 is located between the fixed frame 601 and the sliding plate 603 and is sleeved on the outside of the first moving rod 602. The connecting plate 605 is fixedly connected to the top end of the first moving rod 602. The connecting plate 605 and the first moving rod 602 can be fixed by bolts, welding, etc. The connecting plate 605 has an L-shaped structure, and pins 606 are fixedly connected to both ends of the connecting plate 605. The pins 606 and the connecting plate 605 are integrally formed. The top of the second mounting plate 2 has a first insertion hole for the insertion of the pin 606. A first handle is fixedly connected to the top of the connecting plate 605. In use, pulling the first handle upwards moves the connecting plate 605, the first moving rod 602, and the sliding plate 603 upwards synchronously, thereby adjusting the longitudinal position of the pin 606. This causes the pin 606 to disengage from the first insertion hole in the second mounting plate 2, thus adjusting the position of the second mounting plate 2. The second mounting plate 2 has two states: one is the unfolded state, in which the second mounting plate 2 and the first mounting plate 1 are on the same plane. Another configuration is the folded state of the second mounting plate 2. In this state, the second mounting plate 2 is folded and stored on the back of the first mounting plate 1. When the second mounting plate 2 is unfolded or folded into place, the first handle is released. Under the action of the first spring 604, the connecting plate 605, the first moving rod 602, and the sliding plate 603 are pushed back to their original positions, so that the pin 606 is inserted into the first socket, thereby locking the position of the second mounting plate 2. Two pins 606 are provided, one for inserting into the first socket when the second mounting plate 2 is unfolded, and the other for inserting into the first socket when the second mounting plate 2 is folded.

[0054] In this embodiment, as Figure 2 and Figure 7 As shown, the construction project cost estimate template also includes a second locking component 7. The second locking component 7 has two sets installed on the first mounting plate 1 and the second mounting plate 2 respectively. The second locking component 7 is used to lock the third mounting plate 3 in the unfolded and retracted positions.

[0055] The second locking assembly 7 includes a connecting plate 701, a second moving rod 702, a limiting plate 703, and a second spring 704. The connecting plates 701 on both sets of the second locking assemblies 7 are respectively fixedly connected to the top of the first mounting plate 1 and the second mounting plate 2 at opposite ends. The connecting plates 701 are bolted to the first mounting plate 1 and the second mounting plate 2. The second moving rod 702 slides through the connecting plate 701. A second through hole is provided on the connecting plate 701, and the second moving rod 702 slides through the second through hole. Position plate 703 is fixedly connected to the second moving rod 702 near its bottom end. Limiting plate 703 and the second moving rod 702 are integrally formed. Second spring 704 is located between connecting plate 701 and limiting plate 703 and is sleeved on the outside of the second moving rod 702. Both ends of the top of the third mounting plate 3 have second insertion holes for the second moving rod 702 to be inserted. The portion of the second moving rod 702 below the limiting plate 703 forms a post, which is inserted into the second insertion hole. A second handle is fixedly connected to the top end of the second moving rod 702. In use, pulling the second handle upwards will cause the second moving rod 702 and the limiting plate 703 to move upwards synchronously, thereby adjusting the longitudinal position of the second moving rod 702 and disengaging it from the second insertion hole. This allows adjustment of the position of the third mounting plate 3. The third mounting plate 3 has two states: an unfolded state, in which the third mounting plate 3 is removed from the receiving cavity 8 on the first mounting plate 1 and the second mounting plate 2; and a retracted state, in which the third mounting plate 3 is retracted into the receiving cavity 8 on the first mounting plate 1 and the second mounting plate 2. After the third mounting plate 3 is adjusted to the unfolded and retracted positions, releasing the second handle will push the second moving rod 702 back to its original position under the action of the second spring 704, allowing the second moving rod 702 to insert into the second insertion hole, thus locking the position of the third mounting plate 3. There are two second insertion holes, one for inserting the second moving rod 702 when the third mounting plate 3 is unfolded, and the other for inserting the second moving rod 702 when the third mounting plate 3 is retracted.

[0056] In this embodiment, as Figure 5 As shown, the top and bottom of the cavity 8 are provided with mounting grooves. A guide rod 9 is fixedly connected in the mounting groove. The guide rod 9 is arranged horizontally and is fixed in the mounting groove by bolts. The top and bottom of the third mounting plate 3 located inside the cavity 8 are fixedly connected with guide sleeves 10 that are slidably connected to the guide rod 9. The guide sleeves 10 are slidably sleeved on the outside of the guide rod 9 and are fixedly connected to the third mounting plate 3 by bolts. During the movement of the third mounting plate 3, the guide sleeves 10 slide on the guide rod 9, which plays a limiting and guiding role for the third mounting plate 3, improving the stability and smoothness of the movement of the third mounting plate 3.

[0057] In this embodiment, as Figure 1 and Figure 8 As shown, the bottom of the first mounting plate 1 is fixedly connected to a first support base plate 12 via a support rod 11, and the bottom of the second mounting plate 2 is fixedly connected to a second support base plate 13 via a support rod 11. The ends of the first support base plate 12 and the second support base plate 13 that are close to each other are rotatably connected via a pivot. The bottom of the first support base plate 12 has a storage groove for accommodating the second support base plate 13. Both the bottom of the first support base plate 12 and the second support base plate 13 are equipped with casters 14, preferably universal casters with brakes. The support rod 11 and the first support base plate 12 provide stability for the first mounting plate 1. The support rod 11 and the second support base plate 13 provide stable support for the second mounting plate 2. The movable wheel 14 can push the combined template of the construction cost estimate to adjust its position, making it convenient to use. The first support base plate 12 and the second support base plate 13 are rotatably connected, so that the second support base plate 13 can be adapted to the unfolding and folding position adjustment of the second mounting plate 2, thereby adaptively adjusting its position. Of course, in other embodiments, the support rod 11 can be a support rod with telescopic function to adjust the height of the first mounting plate 1 and the second mounting plate 2 to suit different users.

[0058] Working principle: During use, the usage status of this construction project cost estimation and budgeting template can be adjusted according to the user's needs. The first usage status is as follows: Figure 10 As shown, the two third mounting plates 3 are housed inside the first mounting plate 1 and the second mounting plate 2. The second mounting plate 2 is in a folded state. At this time, only the first mounting plate 1 can be used to assemble the template 4. The second usage state is as follows... Figure 9 As shown, the two third mounting plates 3 are in a stowed state, and the second mounting plate 2 is in an unfolded state. The first mounting plate 1 and the second mounting plate 2 can be used with the template 4; the third usage state is as follows: Figure 1 As shown, the second mounting plate 2 is in the unfolded state, and the two third mounting plates 3 are in the unfolded state. At this time, the first mounting plate 1, the second mounting plate 2, and the two third mounting plates 3 can all be equipped with the template 4. In the fourth usage state, based on the third usage state, one of the third mounting plates 3 is in the unfolded state, and the other third mounting plate 3 is in the stowed state. At this time, the first mounting plate 1, the second mounting plate 2, and one of the third mounting plates 3 can be equipped with the template 4. Thus, the template utilization rate can be improved and the horizontal space occupied can be reduced according to the usage needs. It is suitable for on-site operations or office environments with limited space.

[0059] When assembling the template 4 with the first mounting plate 1, the second mounting plate 2, and the third mounting plate 3, the positioning pins 401 on the template 4 are aligned and inserted into the positioning holes 5. When the end face of the positioning pin 401 abuts against the inner wall of the positioning hole 5, the assembly is in place. At this time, the template 4 is lowered. Under the action of gravity, the template 4 moves slightly downward, so that the locking block 402 is locked into the slot 501, thereby fixing the position of the template 4. When disassembling and replacing the template 4, the template 4 can be lifted slightly upward to disengage the locking block 402 from the slot 501. Then, the template 4 can be moved horizontally to disassemble and remove the template 4, making the replacement of the template 4 convenient and quick.

[0060] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
